Definitions

  • This invention relates to devices for welding thermoplastic parts by generating and aiming infrared energy.
  • Heat welding can be used to join two or more laminar plastic parts together at discrete points.
  • the discrete points can be at points between layered parts, or at points along edges of the parts, or where the two parts abut one another. This process is often used to join overlying parts of automotive door panels.
  • Lasers provide a focused beam of light, but are expensive, and there are dangers associated with laser radiation. Personnel working with lasers usually require a laser radiation shield which adds further expense to the operation of a laser system. Lasers also generate a substantial amount of heat at the laser diode. This heat must be removed, and is therefore not available at the point of welding.
  • thermoplastic parts and plunge sealing film and fabric materials by ultrasonic energy is well known.
  • the workpiece is supported on an anvil.
  • An electroacoustic transducer coupled to a horn dimensioned to be resonant for high frequency vibrations of predetermined frequency is brought into forced engagement with the workpiece for a fixed time interval or an interval which may be determined by process variables such as ,energy transfer or horn travel distance.
  • ultrasonic energy is transmitted to the workpiece to soften the thermoplastic material of the workpiece.
  • the softened and flowed material rigidities, thereby establishing a bond or a weld.
  • the term "ultrasonic” refers to vibrations having a frequency ranging generally between about 10 KHz to about 100 KHz.
  • the ultrasonic power transmitted to the thermoplastic parts is dependent on four parameters: namely, the frequency of the electroacoustic transducer, the force or clamping pressures applied to the thermoplastic parts by the horn, the motional amplitude of the horn as it transmits the energy to the thermoplastic parts and the duration of the energy transfer. It will be appreciated that there are other parameters which can affect an ultrasonic weld as well.
  • the trigger force i.e., the force between the horn and the thermoplastic part below which no ultrasonic energy is initially applied, the feed or down speed of the horn, and the time during which power is increased or decreased may all affect the weld.
  • ultrasonic methods heat up larger areas, and require more intimate contact between parts to be joined.
  • thermoplastics that is energy efficient and that is simple and compact in construction, and which overcomes the problems associated with prior devices.
  • the present invention provides a welding apparatus for joining thermoplastic parts.
  • the invention includes an energy source for generating infrared energy, and an energy directing means for collecting and aiming or directing the infrared energy to a spot on an adjacent thermoplastic part or combination of parts.
  • the apparatus forms a small spot on the exposed and underlying parts to soften and fuse them together in a localized fashion.
  • a preferred embodiment utilizes at least one broadband incandescent lamp as the infrared energy source. This lamp is preferably a halogen lamp.
  • the energy directing function can be performed by one or more reflectors which are preferably gold plated to provide a preferentially high reflectivity of the infrared radiation, thus increasing the percentage of total energy produced reaching the spot to be welded.
  • the illustrative embodiments hereinafter described are packaged in generally cylindrical form with a cylindrical body which houses one or more lamps and one or more reflectors which direct infrared energy out through an aperture.
  • the aperture may be formed in an endcap which is brought into proximity with the workpieces when welding is to be performed.
  • the apparatus may also include a spacer that provides for placing the welder the correct distance from the surface or surfaces to be welded.
  • the apparatus includes two reflectors.
  • the first reflector is disposed in surrounding relationship to the incandescent lamp, and directs the energy to a second reflector.
  • the second reflector then redirects the infrared energy through the aforementioned aperture.
  • the two reflector design provides for easier access to the incandescent lamps or lamps in the body of the device.
  • the apparatus includes a light pipe which acts as an extension of the end cap to provide greater control in directing the radiant energy.
  • the extension also allows for the concentration of energy in areas, such as depressions, which are difficult to reach.
  • the apparatus includes fiber optic cables for directing and focusing the infrared energy.
  • the fiber optic cables are arrayed to direct all energy exiting the cables to a single spot.
  • Figure 1 is a side elevation view of an infrared welder according to a first embodiment of the invention
  • Figure 2 is a cross-sectional view taken along line 2-2 of Figure
  • Figure 3 is a side elevation view of a secondary reflector in the infrared welder of Figures 1 and 2;
  • Figure 4 is an exploded view of the infrared welder of Figures 1 and 2;
