Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as modes for carrying out the present invention.

(A) Configuration of Electronic Component Mounting Device FIG. 1 shows an electronic component mounting device 10. The electronic component mounting apparatus 10 includes one system base 12 and two electronic component mounting machines (hereinafter, may be abbreviated as “mounting machines”) 14 adjacent on the system base 12. Yes. The direction in which the mounting machines 14 are arranged is referred to as the X-axis direction, and the horizontal direction perpendicular to the direction is referred to as the Y-axis direction.

Each mounting machine 14 mainly includes a mounting machine main body 20, a transport device 22, a mounting head moving device (hereinafter also referred to as “moving device”) 24, a mounting head 26, a supply device 28, and a nozzle station 30. ing. The mounting machine main body 20 includes a frame portion 32 and a beam portion 34 that is overlaid on the frame portion 32.

The transport device 22 includes two

conveyor devices

40 and 42. The two

conveyor devices

40 and 42 are disposed in the frame portion 32 so as to be parallel to each other and extend in the X-axis direction. Each of the two

conveyor devices

40 and 42 conveys a circuit board supported by the

conveyor devices

40 and 42 in the X-axis direction by an electromagnetic motor (not shown). The circuit board is held at a predetermined position by a board holding device (not shown).

The moving device 24 is an XY robot type moving device. The moving device 24 includes an electromagnetic motor (not shown) that slides the slider 50 in the X-axis direction and an electromagnetic motor (not shown) that slides in the Y-axis direction. A mounting head 26 is attached to the slider 50, and the mounting head 26 is moved to an arbitrary position on the frame portion 32 by operation of two electromagnetic motors.

The mounting head 26 mounts electronic components on the circuit board. A suction nozzle 60 is provided on the lower end surface of the mounting head 26. As shown in FIG. 2, the suction nozzle 60 includes a body cylinder 64, a flange portion 66, a suction pipe 68, and a latch pin 70. The body cylinder 64 has a cylindrical shape, and the flange portion 66 is fixed so as to overhang the outer peripheral surface of the body cylinder 64. The suction pipe 68 has a thin pipe shape, and is held by the trunk cylinder 64 so as to be movable in the axial direction while extending downward from the lower end portion of the trunk cylinder 64. The latch pin 70 is provided at the upper end portion of the trunk cylinder 64 so as to extend in the radial direction of the trunk cylinder 64. The suction nozzle 60 is detachably attached to the mounting head 26 using the latch pin 70 with one touch. Further, the mounting head 26 includes a spring (not shown), and the spring applies an elastic force to the suction pipe 68 of the suction nozzle 60 attached to the mounting head 26. Thereby, the suction pipe 68 is urged in a direction extending downward from the lower end portion of the body cylinder 64 by the elastic force of the spring built in the mounting head 26.

Also, the suction nozzle 60 communicates with a positive / negative pressure supply device (not shown) via negative pressure air and positive pressure air passages. Each suction nozzle 60 sucks and holds the electronic component with a negative pressure, and detaches the held electronic component with a positive pressure. The mounting head 26 has a nozzle lifting / lowering device (not shown) that lifts and lowers the suction nozzle 60. The mounting head 26 changes the vertical position of the electronic component to be held by the nozzle lifting device.

The supply device 28 is a feeder-type supply device, and has a plurality of tape feeders 76. The tape feeder 76 accommodates the taped component in a wound state. The taped component is a taped electronic component. Then, the tape feeder 76 sends out the taped parts by a feeding device (not shown). Thereby, the feeder type supply device 28 supplies the electronic component at the supply position by feeding the taped component.

The nozzle station 30 accommodates a plurality of suction nozzles 60 and has a nozzle tray 78. As shown in FIG. 3, the nozzle tray 78 includes a base plate 80 and a cover plate 82, and the cover plate 82 is slidably disposed on the base plate 80. A 2D code 84 is written on the corner of the upper surface of the base plate 80, and the 2D code 84 is exposed when the cover plate 82 slides with respect to the base plate 80. On the other hand, as shown in FIG. 4, the 2D code 84 is covered by the cover plate 82 in a state where the base plate 80 and the cover plate 82 are entirely overlapped.

A plurality of mounting holes 86 are formed in the base plate 80. As shown in FIG. 5, which is a cross-sectional view taken along line VV in FIG. 3, the mounting hole 86 is a stepped through hole and has a step surface 88. The inner diameter of the step surface 88 is slightly larger than the outer diameter of the flange portion 66 of the suction nozzle 60, and the flange portion 66 of the suction nozzle 60 is placed on the step surface 88. Thereby, the suction nozzle 60 is placed in the placement hole 86.

Further, the cover plate 82 is also formed with a hole 90 corresponding to the plurality of mounting holes 86 of the base plate 80. The extraction hole 90 is configured by a circular hole portion 96 and a slot portion 98. The circular hole portion 96 is circular and has an inner diameter slightly larger than the stepped surface 88 of the mounting hole 86. The slot portion 98 is a portion cut out at the edge of the circular hole portion 96 and is a cutout portion slightly larger than the outer diameter of the body cylinder 64 of the suction nozzle 60.

In the nozzle tray 78 having the above structure, the cover plate 82 is slid with respect to the base plate 80 to switch between a state in which a part of the mounting hole 86 is exposed and a state in which the entire mounting hole 86 is exposed. Specifically, as shown in FIG. 4, in the state where the entire mounting hole 86 is exposed (hereinafter referred to as “totally exposed state”), the center of the mounting hole 86 and the circular hole portion 96 of the extraction hole 90 are formed. The center coincides and the stepped surface 88 of the mounting hole 86 is completely exposed. For this reason, it is possible to place the suction nozzle 60 in the placement hole 86 or to take out the suction nozzle 60 from the placement hole 86 in the fully exposed state.

On the other hand, as shown in FIG. 3, in a state where a part of the mounting hole 86 is exposed (hereinafter referred to as a “partially exposed state”), the center of the mounting hole 86 and the circular hole portion 96 of the extraction hole 90. The cover plate 82 covers a part of the step surface 88 of the mounting hole 86. For this reason, in the partially exposed state, it is not possible to place the suction nozzle 60 in the placement hole 86 or to remove the suction nozzle 60 from the placement hole 86. However, in the partially exposed state, the center of the mounting hole 86 coincides with the center of the slot portion 98 of the extraction hole 90, and the body of the suction nozzle 60 mounted in the mounting hole 86 as shown in FIG. The cylinder 64 extends from the slot portion 98 above the cover plate 82.

Further, the cover plate 82 is urged in a direction in which it is partially exposed by a spring (not shown). In other words, normally, the suction nozzle 60 is not allowed to be accommodated in the nozzle tray 78 or taken out from the nozzle tray 78. However, the nozzle station 30 has a moving mechanism (not shown) that slides the cover plate 82 in the fully exposed state against the elastic force of the spring. Accordingly, the cover plate 82 is slid by the operation of the moving mechanism, whereby the suction nozzle 60 can be accommodated in the nozzle tray 78 or can be taken out from the nozzle tray 78. The nozzle tray 78 is detachable from the nozzle station 30, and the collection of the suction nozzle 60 accommodated in the nozzle station 30, the replenishment of the suction nozzle 60 to the nozzle station 30, etc. can be performed outside the mounting machine 14. .

(B) Mounting Work by Mounting Machine With the above-described configuration, the mounting machine 14 can perform the mounting work by the mounting head 26 on the circuit board held by the transfer device 22. Specifically, the circuit board is transported to the work position in accordance with a command from a control device (not shown) of the mounting machine 14, and is held by the board holding device at that position. Further, the tape feeder 76 sends out the taped parts and supplies the electronic parts at the supply position in accordance with a command from the control device. Then, the mounting head 26 moves above the supply position of the electronic component and sucks and holds the electronic component by the suction nozzle 60. Subsequently, the mounting head 26 moves above the circuit board and mounts the held electronic component on the circuit board.

In the mounting machine 14, as described above, the electronic component supplied by the tape feeder 76 is sucked and held by the suction nozzle 60, and the electronic component is mounted on the circuit board. For this reason, when a malfunction occurs in the suction nozzle 60, there is a possibility that the mounting operation cannot be performed properly, and it is necessary to manage the suction nozzle 60 appropriately. Therefore, the suction nozzle 60 is managed by the nozzle management device described below.

(C) Configuration of Nozzle Management Device As shown in FIG. 6, the nozzle management device 100 has a generally rectangular parallelepiped shape, and a nozzle tray 78 is accommodated in the nozzle management device 100 on the front or the nozzle management device 100. A door 102 is provided for taking out the nozzle tray 78 from the door. Above the door 102, a display panel 106 for displaying various types of information is disposed.

As shown in FIG. 7, the nozzle management device 100 includes a management device main body 110, a pallet storage device 112, a nozzle transfer device 114, a nozzle inspection device 116, a nozzle cleaning device 118, and a control device (see FIG. 9) 120. ing. FIG. 7 is a perspective view showing a state in which the outer shell member of the nozzle management apparatus 100 is removed, and shows the internal structure of the nozzle management apparatus 100.

The management apparatus main body 110 is configured by a frame part 126 and a beam part 128 overlaid on the frame part 126. The frame portion 126 has a hollow structure. The pallet accommodating device 112 is disposed in the frame portion 126, and the upper end portion of the pallet accommodating device 112 is exposed on the upper surface of the frame portion 126.

The pallet storage device 112 includes a plurality of pallet placement shelves 130 and a support arm 132. The pallet mounting shelf 130 is a shelf for mounting the nozzle pallet 136, and a plurality of pallet mounting shelves 130 are arranged in the vertical direction inside the frame portion 126. A plurality of suction nozzles 60 are accommodated in the nozzle pallet 136. The support arm 132 moves in the vertical direction in front of the plurality of pallet placement shelves 130 by the operation of an arm moving device (not shown), and approaches and separates from the pallet placement shelves 130. As a result, the support arm 132 performs the storage of the nozzle pallet 136 on the pallet mounting shelf 130 and the removal of the nozzle pallet 136 from the pallet mounting shelf 130. The nozzle pallet 136 taken out from the pallet mounting shelf 130 moves to the upper surface side of the frame portion 126 as the support arm 132 moves upward.

The nozzle transfer device 114 is a device for transferring the suction nozzle 60 between the nozzle tray 78 and the nozzle pallet 136 and the like, and is disposed in the beam unit 128. The nozzle transfer device 114 includes a transfer head 150 and a head moving device 152. A camera 156 facing downward and a holding chuck 158 for holding the suction nozzle 60 are attached to the lower end surface of the transfer head 150.

The holding chuck 158 includes a main body 160 and a pair of holding claws 162 as shown in FIG. The pair of holding claws 162 are slidably held on the lower surface of the main body 160, and approach and separate. Then, when the pair of holding claws 162 approach, the suction nozzle 60 is held in the trunk cylinder 64, and when the pair of holding claws 162 are separated, the held suction nozzle 60 is released.

In addition, an air flow path 166 is formed in the main body 160 of the holding chuck 158. One end of the air flow path 166 opens between the pair of holding claws 162, and the other end is connected to the air supply device 168. For this reason, in the state where the holding chuck 158 holds the suction nozzle 60, the air is supplied to the air flow path 166 by the air supply device 168, whereby the air is blown into the suction nozzle 60. As a result, air is blown from the body cylinder 64 of the suction nozzle 60, and air is blown from the tip of the suction pipe 68.

Further, the head moving device 152 is an XYZ type moving device that moves the transfer head 150 in the front-rear direction, the left-right direction, and the up-down direction above the frame portion 126, as shown in FIG. A plurality of fixed stages 170 on which the nozzle tray 78 is placed are provided on the upper surface on the front side of the frame portion 126. The fixed stage 170 has a moving mechanism (not shown) that slides the cover plate 82 of the mounted nozzle tray 78 in a fully exposed state. As a result, the suction nozzle 60 is transferred between the nozzle tray 78 that is fully exposed by the fixed stage 170 and the nozzle pallet 136 of the pallet storage device 112 by the operation of the nozzle transfer device 114.

Also, the nozzle inspection device 116 has a load cell 178. The load cell 178 is disposed on the upper surface of the frame part 126, and the load cell 178 is used to inspect the expansion / contraction state of the tip of the suction nozzle 60. Specifically, the suction nozzle 60 to be inspected is held by the holding chuck 158, and the tip of the suction nozzle 60 held by the holding chuck 158 is brought into contact with the load cell 178. As described above, the tip end portion of the suction nozzle 60 can be expanded and contracted, and the extension state of the tip portion of the suction nozzle 60 is inspected based on the load measured by the load cell 178. That is, the load when the tip of the suction nozzle 60 contracts from the extended state is measured, and the stretched state of the tip of the suction nozzle 60 is inspected based on the load.

Note that, in the suction nozzle 60 held by the holding chuck 158, the suction tube 68 normally extends from the body cylinder 64 by its own weight, so that the tip of the suction nozzle 60 is extended. However, when the sliding state between the body cylinder 64 and the suction pipe 68 is poor, the tip of the suction nozzle 60 may not be extended. For this reason, before the inspection by the load cell 178 is performed, air is supplied to the air flow path 166 by the air supply device 168 in the holding chuck 158 holding the suction nozzle 60. At this time, air is blown out of the body cylinder 64 into the suction nozzle 60 held by the holding chuck 158. As a result, air is blown out from the tip of the adsorption tube 68, and the adsorption tube 68 extends from the body cylinder 64 by blowing out air. That is, the tip of the suction nozzle 60 extends. Thereby, it is possible to appropriately perform the inspection by the load cell 178.

Further, the nozzle cleaning device 118 is a device for cleaning and drying the suction nozzle 60 and is disposed next to the pallet housing device 112. The nozzle cleaning device 118 includes a cleaning / drying mechanism 180 and a cleaning pallet moving mechanism 182. The cleaning / drying mechanism 180 is a mechanism for cleaning and drying the suction nozzle 60 inside. Further, the cleaning pallet moving mechanism 182 moves the cleaning pallet 188 between the exposed position where the cleaning pallet 188 is exposed (the position where the cleaning pallet 188 is illustrated in FIG. 7) and the inside of the cleaning / drying mechanism 180. It is a mechanism to make. That is, in the nozzle cleaning device 118, the cleaning pallet 188 on which the suction nozzle 60 is placed is moved into the cleaning / drying mechanism 180, and the suction nozzle 60 is cleaned and dried while being placed on the cleaning pallet 188. Is done.

Note that a mark (not shown) is marked on the cleaning pallet 188, and the position of the cleaning pallet 188 is recognized by capturing the mark with the camera 156. However, since the cleaning pallet 188 is cleaned by the nozzle cleaning device 118 together with the suction nozzle 60, water droplets may adhere to the mark. In such a case, there is a possibility that the mark cannot be properly imaged with water droplets and the position of the cleaning pallet 188 cannot be properly recognized. Therefore, before the mark on the cleaning pallet 188 is imaged by the camera 156, the holding chuck 158 is moved above the cleaning pallet 188, and air is ejected toward the cleaning pallet 188 by the operation of the air supply device 168. Is done. At this time, water droplets adhering to the cleaning pallet 188 are blown off by the air. As a result, the mark on the cleaning pallet 188 can be appropriately imaged and the position of the cleaning pallet 188 can be recognized.

Further, although the nozzle cleaning device 118 is also dried, moisture may remain inside the suction nozzle 60. In particular, in the suction nozzle 60, the body cylinder 64 and the suction pipe 68 slide, so that moisture may remain on the sliding surface between the body cylinder 64 and the suction pipe 68. Therefore, the suction nozzle 60 that has been cleaned is held by the holding chuck 158, and air is supplied to the air flow path 166 by the air supply device 168 in the holding chuck 158 that holds the suction nozzle 60. As a result, air is blown out from the body cylinder 64 into the suction nozzle 60 held by the holding chuck 158, and the moisture on the sliding surface between the body cylinder 64 and the suction pipe 68 can be removed.

Further, as shown in FIG. 9, the control device 120 includes a controller 200, a plurality of drive circuits 202, a control circuit 204, and a memory 206. The plurality of drive circuits 202 are connected to the pallet storage device 112, the nozzle transfer device 114, the nozzle inspection device 116, and the nozzle cleaning device 118. The controller 200 includes a CPU, a ROM, a RAM, and the like, mainly a computer, and is connected to a plurality of drive circuits 202. Thereby, the operations of the pallet storage device 112, the nozzle transfer device 114, and the like are controlled by the controller 200. Further, the controller 200 is connected to the display panel 106 via the control circuit 204, and a predetermined image is displayed on the display panel 106 according to a command from the controller 200. Further, a memory 206 is connected to the controller 200, and the controller 200 writes information to the memory 206 and reads information from the memory 206.

(D) Adsorption nozzle management by the nozzle management device In the nozzle management device 100, the adsorption nozzle 60 is cleaned in order to appropriately manage the adsorption nozzle 60 with the above-described configuration. Specifically, the operator places the nozzle tray 78 in which the suction nozzle 60 to be cleaned is accommodated on the fixed stage 170 of the nozzle management apparatus 100. In the nozzle management apparatus 100, when the nozzle tray 78 is placed on the fixed stage 170, the cover plate 82 of the nozzle tray 78 is slid by the moving mechanism, and the nozzle tray 78 is changed from the partially exposed state to the fully exposed state.

Next, all the suction nozzles 60 accommodated in the nozzle tray 78 are transferred to the cleaning pallet 188 of the nozzle cleaning device 118 by the nozzle transfer device 114. At this time, the cleaning pallet 188 is moved to the exposure position by the operation of the cleaning pallet moving mechanism 182. When the transfer of the suction nozzle 60 to the cleaning pallet 188 is completed, the cleaning pallet 188 is moved into the cleaning / drying mechanism 180 by the operation of the cleaning pallet moving mechanism 182, and the suction nozzle 60 is cleaned and dried. Done. When the cleaning and drying of the suction nozzle 60 by the cleaning / drying mechanism 180 is completed, the cleaning pallet 188 is moved from the cleaning / drying mechanism 180 to the exposed position by the operation of the cleaning pallet moving mechanism 182.

Further, by transferring the suction nozzle 60 to the cleaning pallet 188, the nozzle tray 78 that does not contain the suction nozzle 60 is cleaned by the ejection of air from the holding chuck 158. Specifically, the holding chuck 158 is moved above the nozzle tray 78 while the suction nozzle 60 is being cleaned and dried in the nozzle cleaning device 118. Then, by the operation of the air supply device 168, air is ejected toward the inside of the mounting hole 86 and the extraction hole 90 of the nozzle tray 78. At this time, the nozzle tray 78 is fully exposed, and the holding chuck 158 is moved so that air is ejected to all of the mounting holes 86 and the extraction holes 90 of the nozzle tray 78. As a result, when foreign matter such as dust adheres to the inside of the mounting hole 86 and the extraction hole 90, the foreign matter is blown away by air, and the nozzle tray 78 is cleaned.

Next, when the cleaning of the nozzle tray 78 by the ejection of air is completed, the camera 156 is moved above the nozzle tray 78. The nozzle tray 78 is imaged by the camera 156, and the imaged data is input to the controller 200. The controller 200 determines whether or not the nozzle tray 78 is properly cleaned based on the imaging data. At this time, when the nozzle tray 78 is not properly cleaned, an image indicating that the nozzle tray 78 is not properly cleaned is displayed on the display panel 106. Thereby, an operator can confirm that the nozzle tray 78 is not properly cleaned, and the nozzle tray 78 can be re-cleaned.

Further, when the nozzle tray 78 is properly cleaned, the holding chuck 158 is moved above the exposed position of the nozzle cleaning device 118. In the nozzle cleaning device 118, when the cleaning and drying of the suction nozzle 60 is completed and the cleaning pallet 188 is moved to the exposure position, the suction nozzle 60 placed on the cleaning pallet 188 is moved by the holding chuck 158. Retained. Subsequently, the suction nozzle 60 held by the holding chuck 158 is transferred to the nozzle tray 78 placed on the fixed stage 170. When all the suction nozzles 60 placed on the cleaning pallet 188 are transferred to the nozzle tray 78, an image indicating that the cleaning of the suction nozzles 60 is completed is displayed on the display panel 106. Upon confirming the image, the operator removes the nozzle tray 78 from the fixed stage 170 and takes it out of the nozzle management apparatus 100. Then, the operator sets the nozzle tray 78 in the nozzle station 30 of the mounting machine 14. Thereby, in the mounting machine 14, the mounting operation is executed by the cleaned suction nozzle 60.

Note that after the suction nozzle 60 is cleaned, the suction nozzle 60 is inspected, that is, the load is measured by the load cell 178, and only the suction nozzle 60 with a good inspection result is transferred to the nozzle tray 78 of the fixed stage 170. Good. Incidentally, the suction nozzle 60 having a poor test result is discarded in a disposal box 208 disposed next to the fixed stage 170.

In the nozzle management device 100, the suction nozzle 60 is replaced in addition to the cleaning and inspection of the suction nozzle 60. Specifically, in the mounting machine 14, the suction nozzle 60 to be used is determined in advance according to the type of mounting work. For this reason, the suction nozzle 60 accommodated in the nozzle tray 78 is replaced before the predetermined mounting operation is completed and the next mounting operation is executed. Therefore, when the predetermined mounting operation is completed, the worker removes the nozzle tray 78 from the nozzle station 30 in the mounting machine 14. Then, the operator sets the nozzle tray 78 on the fixed stage 170 of the nozzle management apparatus 100.

In the nozzle management device 100, all the suction nozzles 60 of the nozzle tray 78 set on the fixed stage 170 are transferred to the nozzle pallet 136 of the pallet accommodation device 112. When all the suction nozzles 60 in the nozzle tray 78 are transferred to the nozzle pallet 136, the holding chuck 158 is moved above the nozzle tray 78. Then, the nozzle tray 78 is cleaned by the ejection of air from the holding chuck 158. The cleaning of the nozzle tray 78 by the ejection of air is the same as the method described above, and thus the description thereof is omitted.

In the pallet accommodating device 112, when all the suction nozzles 60 of the nozzle tray 78 are transferred to the nozzle pallet 136, the nozzle pallet 136 is lowered and stored in the pallet mounting shelf 130. Further, the type of suction nozzle 60 required for the mounting operation by the mounting machine 14 is input to the nozzle management apparatus 100, and the nozzle pallet 136 on which the suction nozzle 60 required for the mounting operation is mounted is mounted on the pallet. It is taken out from the shelf 130 by the support arm 132.

Next, the nozzle pallet 136 on which the suction nozzle 60 necessary for the mounting operation is placed is moved above the frame portion 126. Subsequently, the suction nozzle 60 necessary for the mounting operation is transferred from the nozzle pallet 136 to the nozzle tray 78 set on the fixed stage 170. When all the suction nozzles 60 necessary for the mounting operation are transferred to the nozzle tray 78, an image indicating that the replacement of the suction nozzles 60 is completed is displayed on the display panel 106. Upon confirming the image, the operator removes the nozzle tray 78 from the fixed stage 170 and takes it out of the nozzle management apparatus 100. Then, the operator sets the nozzle tray 78 in the nozzle station 30 of the mounting machine 14. Thereby, in the mounting machine 14, a new mounting operation is executed by the replaced suction nozzle 60.

As described above, the nozzle tray 78 is cleaned in the nozzle management device 100 before the nozzle tray 78 is set in the nozzle station 30 of the mounting machine 14. Thereby, it is possible to prevent foreign matters such as dust from entering the mounting machine 14. In particular, in the nozzle tray 78, since the base plate 80 is covered by the slide of the cover plate 82, it is difficult to remove foreign matters such as dust. However, in the nozzle management device 100, air is placed in the mounting hole 86 and the like in the fully exposed state. Erupted. Thereby, it is possible to suitably remove foreign matters such as dust from the nozzle tray 78.

In the nozzle management device 100, the nozzle tray 78 is cleaned while the suction nozzle 60 is being cleaned. That is, the nozzle tray 78 is cleaned using the time required for cleaning the suction nozzle 60 and the like. Thereby, time can be used effectively.

Furthermore, as described above, the air supply device 168 used for cleaning the nozzle tray 78 is the object to be cleaned that has been cleaned by the nozzle cleaning device 118, that is, water droplets attached to the suction nozzle 60 and the cleaning pallet 188. Used for blowing away. The air supply device 168 is also used when the tip of the suction nozzle 60 is extended. That is, the air supply device 168 is not a device provided exclusively for cleaning the nozzle tray 78 but a device provided for performing other operations. Thereby, it becomes possible to suppress an increase in cost by diverting an existing device without adding a new device.
