[0046] In an embodiment of the present invention, a guiding frame 6 is provided between the loading frame 4 and the unloading frame 41. Guide plates 61 are arranged on both sides of the guiding frame 6, and a guiding channel 62 for guiding the tray is formed between the two guide plates 61. Both ends of the guiding channel 62 are respectively communicated with the loading frame 4 and the unloading frame 41.

[0047] Specifically, both ends of the guiding channel 62 are respectively communicated with the loading frame 4 and the unloading frame 41. After the material handling and unloading of the tray are completed, the pushing linear module 71 drives the pushing plate 73 on the pushing frame 72 to push the empty tray on the clamping mechanism 5 along the guiding channel 62 to the unloading frame 41. The guiding channel 62 can play a role in carrying and guiding the empty tray, enabling it to accurately fall on the unloading frame 41, avoiding the possible position deviation phenomenon of the tray during the guiding process, and enabling the conveyed tray to be smoothly transported.

[0048] In an embodiment of the present invention, the loading frame 4 and the unloading frame 41 have the same structure. The loading frame 4 includes a plurality of support plates 42, and the plurality of support plates 42 enclose to form a loading frame. An inlet 43 is arranged on the loading frame.

[0050] In an embodiment of the present invention, the receiving component 8 includes a receiving frame. A lifting module 81 is arranged on the receiving frame. The lifting module 81 is drivingly connected with a receiving support 82. A plurality of receiving plates 83 are arranged on the receiving support 82, and the plurality of receiving plates 83 form a loading station for placing the trays.

[0051] Specifically, the lifting module 81 drives the receiving plate 83 on the receiving support 82 to move upward, so that the loading stations formed by multiple receiving plates 83 integrally lift the stacked trays, making the gap between the two uppermost trays of the stacked trays opposite to the material taking support plate 54. Its structure is simple and the cost is low, greatly improving the production efficiency.

[0052] In an embodiment of the present invention, the loading track 11 and the unloading track 12 have the same structure.

[0054] Usage process

[0055] Stack the material-carrying trays loaded with materials on the loading track 11. The track motor 15 drives the drive shaft 14 to rotate to synchronously drive the two belt conveyors 13 to run, and transfer the stacked trays to the feeding port 43. The centering cylinder 44 drives the centering plate 45 to perform on-line centering and positioning on the stacked trays on the loading track 11, ensuring the position accuracy of the stacked trays, and can more accurately transfer the stacked trays into the loading frame. The lifting module 81 drives the receiving plate 83 on the receiving bracket 82 to move upward, so that the bearing stations formed by multiple receiving plates 83 integrally lift the stacked trays, making the gap between the two uppermost trays of the stacked trays opposite to the material-taking support plate 54. The clamping cylinder 52 drives the material-taking support plate 54 to be inserted into the gap between the two trays. The lifting module 81 drives the receiving plate 83 on the receiving bracket 82 to move downward to place the stacked trays on the loading track 11. The piston rod of the pushing cylinder 55 passes through the clamping bracket 53 and is drivingly connected to the pushing plate 56. The pushing cylinder 55 drives the pushing plate 56 to tightly press and position the two sides of the tray. The driving linear module 21, the lifting linear module 23 and the transverse linear module (not shown) form a three-axis linear module, driving the material-taking gripper 3 to move above the tray. The lifting cylinder 36 drives the material-taking gripper 3 on the lifting bracket 35 to move towards the material direction. After the positioning pin 34 first contacts the positioning position (hole, groove or protrusion, etc.) on the material, the jaw cylinder 31 drives the two clamping plates 32 to clamp the material positioned by the positioning pin 34. Driven by the three-axis linear module, the material is transferred to the loading position. When the material handling and unloading of the tray are completed, the pushing cylinder 55 drives the pushing plate 56 to move away from the tray. The pushing linear module 71 drives the pushing plate 73 on the pushing frame 72 to push the empty tray on the clamping mechanism 5 along the guiding channel 62 to the unloading frame 41. The receiving component 8 on the unloading frame 41 is used to receive the empty tray and stack the empty trays one by one on the unloading frame 41. The receiving component 8 on the unloading frame 41 then discharges the stacked empty trays onto the unloading track 12, and the unloading track 12 unloads the stacked empty trays, thus completing the loading and unloading operations of the processing.
