The principle of the automatic material inversion cleaning device 1 is as follows: when the printing surface of the glass is on the reverse side, the glass is placed on the first vacuum adsorption plate 112, and the inversion cylinder 111 is activated, so that the printing surface of the glass is on the front side. The vacuum suction plate 112 is an L-shaped plate, and the notch faces the first vacuum suction platform 123 , which is very convenient for turning the vacuum suction plate 112 , and prevents the vacuum suction plate 112 from being blocked by the first vacuum suction platform 123 when it is turned over. At this time, the glass is located above the first vacuum adsorption platform 123 , and the glass is placed on the first vacuum adsorption platform 123 . The turning cylinder 111 is turned back to its original position again, so that the vacuum suction plate 112 is returned to its original position and waits for the next glass placement.

If the printing surface of the glass is on the front side, the glass does not need to be turned over by the turning mechanism 11 , and the glass can be directly placed on the first vacuum adsorption platform 123 . Since the printing direction of the glass is required, when the printing direction of the glass placed on the first vacuum adsorption platform 123 is not correct, the rotating cylinder 122 needs to be activated to rotate the glass to adjust the printing direction of the glass. If the printing direction of the glass is correct, the rotating cylinder 122 does not need to be activated to rotate the glass, and the X-direction linear module 121 drives the rotating cylinder 122 and the first vacuum adsorption platform 123 to move linearly together, so that the glass passes under the dust removal mechanism 13 .

The inclination direction of the inclined opening groove 1314 is toward the upper side of the turning mechanism 11 . The surfaces of the two ends of the movable bearing 1311 in sliding contact with the inclined opening grooves 1314 are flat surfaces. When the glass passes under the sticker roller 1312, the glass will push up the moving bearing 1311, so that the sticker roller 1312 is close to the glass. When the adhesive on the sticker roller 1312 cannot be used, the outermost sticker is torn off, and the inner sticker is exposed to continue sticking the dust of the glass.

The inclined opening slot 1314 has a U-shaped structure, that is, the upper and lower surfaces of the inclined opening slot 1314 are flat surfaces. In order to ensure that the movable bearing 1311 can only slide linearly in the U-shaped structure, the two ends of the movable bearing 1311 are in sliding contact with the inclined opening slot 1314. The surface of the roller is also set to be flat, so the moving bearing 1311 can only slide up in a straight line and obliquely, so as to ensure that only the sticker roller 1312 rolls, and the dust removal effect is better. The plasma cleaning machine 132 is a conventional device used for the second cleaning of the glass surface.
