The material tray circulation device provided in the embodiment of the present application includes a circulation mechanism and a positioning component.

[0047] The circulation mechanism comprises a feeding area and a discharging area arranged adjacent to each other, wherein a plurality of material trays are stacked in the feeding area and the discharging area, and the material trays can circulate back and forth between the feeding area and the discharging area;

[0048] The positioning component is arranged above the loading area and is used to position the uppermost material tray in the loading area during the material tray circulation process to prevent the material tray from moving during loading.

[0049] The embodiment of the present application can realize the back and forth circulation of the material tray in the loading area and the unloading area through the circulation mechanism, and the empty material tray can be filled with material during the circulation process, and the material tray can flow into the next process after it is full of material. The embodiment of the present application can omit the assembly line with a large floor space, so that the production space can be reasonably utilized and the production cost is reduced;

[0050] Furthermore, the positioning assembly can position the material tray above the loading area to prevent the material tray from moving during loading, while supporting the material tray during loading to prevent the material from being too heavy and causing damage to the material tray located in the loading area.

[0051] The circulation mechanism in the embodiment of the present application may include two upper robots and a lower robot respectively arranged above or below the loading area and the unloading area. The upper robot can place the uppermost material tray in the loading area on the positioning component for positioning. After the material tray is full of material, the full material tray is placed above the material tray in the unloading area. The lower robot can move the lowermost material tray in the unloading area to below the lowermost material tray in the loading area, so as to realize the circulation of the material tray.

[0052] Preferably, the circulation mechanism comprises a cabinet 1, a rack assembly 2 and a circulation device:

[0053] The cabinet 1 includes a first transplanting area 11, a positioning area 12 and a second transplanting area 13 in sequence along the vertical direction, wherein the positioning area 12 includes a loading port 121 and a unloading port 122;

[0055] The circulation device includes a first transplanting component 3 and a second transplanting component 4. The first transplanting component 3 is arranged in the first transplanting area 11. The first transplanting component 3 is used to transplant the material tray of the upper material area 21 from the upper material port 121 to the lower material area 22 below the lower material port 122. The second transplanting component 4 is used to transplant the material tray at the bottom of the lower material area 22 to below the material tray at the bottom of the upper material area 21.

[0056] The positioning assembly 5 is disposed at the loading port 121 of the positioning area 12, and is used to position the uppermost material tray of the loading area 21 to prevent the material tray from moving during loading.

[0057] After the rack assembly 2 with full and empty trays is pushed into the first transfer area 11 of the cabinet 1 in the embodiment of the present application, the first transfer assembly 3 places the empty tray at the top of the loading area 21 of the rack assembly 2 on the positioning assembly 5 in the positioning area 12. After the tray at the top of the loading area 21 of the rack assembly 2 is full of materials, the first transfer assembly 3 transfers the full tray from the loading port 121 of the positioning area 12 to the unloading port 122, and stacks the full tray above the top tray in the unloading area 22 of the rack assembly 2. The second transfer assembly 4 transfers the bottom tray in the unloading area 22 to the bottom tray in the loading area 21. In this way, the tray circulation is realized. After multiple cycles, the empty trays on the rack assembly 2 can be filled with materials, and then the rack assembly 2 can be moved out to enter the next process. The embodiment of the present application can omit the assembly line with a large floor space, so that the production space is reasonably utilized and the production cost is reduced.

[0058] Furthermore, the positioning component 5 can position the material tray after the first transplanting component 3 moves the material tray of the loading area 21 to the loading port 121 of the positioning area 12 to prevent the material tray from moving during loading, while supporting the material tray during loading to prevent the material from being too heavy and causing damage to the material tray in the loading area 21.

[0059] The loading area 21 and the unloading area 22 of the rack assembly 2 in the embodiment of the present application are arranged adjacent to each other in the horizontal direction. After the rack assembly 2 is transferred into the second transfer area 13 of the cabinet 1, the loading area 21 and the unloading area 22 correspond to the loading port 121 and the unloading port 122 of the positioning area 12, respectively. A partition is arranged between the loading area 21 and the unloading area 22, and a through slot is arranged below the partition.

When the rotating drive assembly drives the two eccentric clamping assemblies to rotate, the spacing between the eccentric clamping assemblies decreases, and the eccentric clamping assemblies can abut against the side wall of the material tray to clamp the material tray. The material tray will not fall during the transportation of the clamp due to the static friction between the eccentric clamping assemblies; when the rotating drive assembly drives the two eccentric clamping assemblies to rotate in the opposite direction, the spacing between the eccentric clamping assemblies becomes larger, and the eccentric clamping assemblies do not abut against the side wall of the material tray to release the material tray; when the clamp of the embodiment of the present application clamps the material tray, the eccentric clamping assembly only contacts the side of the material tray, and does not contact the transport device or adjacent material tray located below the material tray.
