The first cylinder 712 and the second cylinder 713 are both mounted on the tray 6. The first clamping plate 711 is mounted above the first cylinder 712 and the second cylinder 713, forming a compact structure. The first cylinder 712 and the second cylinder 713 drive the two ends of the first clamping plate 711 with the tray 6 as the fulcrum, causing the first clamping plate 711 to move closer to or away from the vertical side surface 81 of the material tray 8. At least one wedge plate 715 is provided at the bottom of the first clamping plate 711. There are two wedge plates 715, which are symmetrically located on both sides of the negative pressure adsorption part 714, so that it has... A material tray 8 of a certain length is evenly supported; the middle of the first clamping plate 711 is provided with air holes 716 facing the vertical surface 81 on the side of the material tray 8, and the number of air holes 716 is not less than 3. The 3 air holes 716 help to adsorb the vertical surface 81 within a certain size range, ensuring the stability of the material tray 8 during the transfer process; the plane 7151 of the wedge plate 715 supports the bottom of the thin edge 82 of the material tray 8, the first clamping plate 711 lightly contacts the vertical surface 81 on the side of the material tray 8, and the negative pressure adsorption part 714 adsorbs the vertical surface 81 on the side of the material tray 8 through the air holes 716; the first clamping plate 715 supports the vertical surface 81 on the side of the material tray 8. The components 71, 72, 73, and 74 have the same structure, that is, each clamping component has a first clamping plate 711, a first cylinder 712, a second cylinder 713, and a negative pressure adsorption part 714. When the first clamping component 71, 72, 73, and 74 approach the material tray simultaneously, the vertical surface 81 of the material tray 8 is lightly contacted by the first clamping plates 711 around the tray. The plane 7151 of the wedge plate 715 supports the bottom of the thin edge 82 of the material tray 8. The negative pressure adsorption part 714 adsorbs the vertical surface 81 on the side of the material tray 8 through the air hole 716.
[0030] Specifically, see Figure 5 and Figure 6 The material tray 8 has a number of regularly arranged protrusions 83 that support the material sheet. The tray 8 has vertical surfaces 81 and sheet edges 82 around its perimeter. See also Figures 1 to 8The support plate 1 is provided with a discharge port 11, and a plurality of guide plates 111 are provided around the discharge port 11. The tray lifting assembly 3 lifts a plurality of stacked trays 8 through the discharge port 11 to the loading port 61. The support plate 1 is provided with a return port 12, which is aligned with the tray recycling assembly 5. The tray transfer assembly 4 transfers a single tray 8 to the return port 12 through the slide rail 2. A plurality of guide plates 121 are provided around the return port 12. The tray recycling assembly 5 receives empty trays 8 one by one through the return port 12.
[0031] See Figures 1 to 8 The feeding, transfer, and recycling process of the material tray 8 is as follows: First, the material tray lifting assembly 3 lifts several stacked material trays 8 to the feeding port 61.

Second, the first cylinders 712 and second cylinders 713 located around the material tray 8 extend synchronously, and the first clamping plates 711 simultaneously approach and lightly touch the vertical surface 81 on the side of the material tray 8. The planes 715 of the wedge plates 715 at the bottom of the first clamping plates 711... 151 supports the thin edge 82 of the uppermost tray 8. The negative pressure adsorption part 714 adsorbs the vertical surface 81 on the side of the tray 8 through the air hole 716. Specifically, the wedge plate 715 has a pointed part, which is composed of a flat surface 7151 and an inclined surface 7152. The pointed part protrudes from the vertical surface 7111 of the first clamping plate 711. When the first clamping plate 711 is close to the vertical surface 81 on the side of the tray 8, the pointed part is inserted into the gap between the two stacked trays 8 and passes through the air hole 716. The inclined plane 7152 gradually binds the lower tray 8 to its original position, and the lower tray 8 remains in place under the combined action of gravity and the inclined plane 7152; in the third step, the robotic arm (not shown) picks up the material pieces placed on the tray 8 through a suction cup (not shown); in the fourth step, the tray transfer assembly 4 transfers the tray 8 to the tray recycling assembly 5. Specifically, a rodless cylinder 13 is provided on one side of the support plate 1, and the rodless cylinder 13 drives the tray 6 to move along the slide rail 2 to the return port 12 through the connecting plate 131, located on the fourth side of the tray 8.

Under the action of gravity, the material tray 8 falls through the return port 12 to the material tray recycling component 5; in the fifth step, the material tray transfer component 4 returns to the position above the discharge port 11, and the material tray lifting component 3 lifts the remaining material tray 8 to a predetermined height; according to the first to the fifth steps above, the cycle repeats, continuously supplying the material pieces carried by the material tray 8. Example 2

Step S2: The first cylinders 712 and the second cylinders 713 located around the material tray 8 extend synchronously, and the first clamping plates 711 simultaneously approach and lightly touch the vertical surface 81 on the side of the material tray 8. The planes 7151 of the wedge plates 715 at the bottom of the first clamping plates 711 support the thin edge 82 of the uppermost material tray 8. The negative pressure adsorption part 714 adsorbs the vertical surface 81 on the side of the material tray 8 through the air holes 716. Specifically, the wedge plates 715 have The tip is composed of a plane 7151 and an inclined plane 7152. The tip protrudes from the vertical plane 7111 of the first clamping plate 711. When the first clamping plate 711 is close to the vertical plane 81 on the side of the material tray 8, the tip is inserted into the gap between the two stacked material trays 8, and the inclined plane 7152 gradually binds the lower material tray 8 to its original position. The lower material tray 8 stays in its original position under the combined action of gravity and the inclined plane 7152. Step S3: The robotic arm (not shown) picks up the material sheet placed in the material tray 8 using a suction cup (not shown); Step S4: The tray transfer assembly 4 transfers the tray 8 to the tray recycling assembly 5. Specifically, a rodless cylinder 13 is provided on one side of the support plate 1. The rodless cylinder 13 drives the tray 6 to move along the slide rail 2 to the return port 12 through the connecting plate 131. The first cylinders 712 and the second cylinders 713 located around the tray 8 retract synchronously, and the first clamping plates 711 move away from the tray 8 synchronously, so that the tray 8 is removed from the suction of the air hole 716 and the support of the wedge plate 715. Under the action of gravity, the tray 8 falls into the tray recycling assembly 5 through the return port 12.
