When the defective tray is conveyed by the two second conveyor belt structures 320 of the defective tray stacking assembly 302 above its tray lifting structure 340, the defective tray can be lifted by its tray lifting structure 340 into the upper tray storage bin 330.

A cover cavity for accommodating covers is formed by enclosing between the plurality of bin limit plates 414 and the bin bottom plate 412. The cover cavity is located above the tray conveying mechanism 200 or the tray stacking mechanism 300 (such as the defective tray stacking assembly 302), and the cover adsorption structure 430 of the cover fastening mechanism 400 is located above the cover cavity. The cover cavity formed by enclosing between the plurality of bin limit plates 414 and the bin bottom plate 412 can stack and store a plurality of covers. When it is necessary to cover a plurality of stacked trays with covers, the pick-and-place driving structure 420 can be used to drive the cover adsorption structure 430 to move to the position of the cover in the cover cavity, adsorb and grab the cover through the cover adsorption structure 430, and drive the cover adsorption structure 430 and the adsorbed cover to move to the plurality of trays stacked by the tray stacking mechanism 300 through the pick-and-place driving structure 420, and fasten the cover on the plurality of stacked trays.

A plurality of covers can be stacked and stored in the cover cavity of the cover storage bin. When it is necessary to cover a plurality of stacked trays with covers, the cover ejection structure can be used to eject the cover in the cover storage bin, and the pick-and-place driving structure 420 can be used to drive the cover adsorption structure 430 to pick up the ejected cover, and transfer and fasten the cover to the plurality of trays stacked by the tray stacking mechanism 300 (qualified tray stacking assembly 304).

[0049] Moreover, the loading and unloading driving structure 420 may include a cover plate horizontal driving member 422 disposed on the frame 100, and a cover plate lifting driving member 424 disposed on the cover plate horizontal driving member 422.

The cover plate horizontal driving member 422 is configured to drive the cover plate adsorption structure 430 to reciprocate horizontally between the cover plate bin structure 410 and the tray storage bin 330. By means of the cover plate horizontal driving member 422, the cover plate lifting driving member 424 and the cover plate adsorption structure 430 can be driven to move horizontally to directly above the cover plate bin structure 410, and the cover plate lifting driving member 424 can be used to drive the cover plate adsorption structure 430 to descend to the position of the cover plate stored in the cover plate bin structure 410, adsorb and grasp the cover plate. Then, the cover plate lifting driving member 424 can be used to drive the cover plate adsorption structure 430 and the adsorbed cover plate to rise. Further, the cover plate horizontal driving member 422 can be used to drive the cover plate adsorption structure 430 and the cover plate to move horizontally to above the tray storage bin 330 of the tray stacking mechanism 300 (qualified tray stacking assembly 304). Then, the cover plate lifting driving member 424 can be used to drive the cover plate adsorption structure 430 and the cover plate to descend to a preset height, so that the cover plate adsorption structure 430 releases the adsorbed cover plate, and the cover plate is closed to the top surface of the multiple stacked trays stored in the tray storage bin 330.

[0050] Further, the cover plate horizontal driving member 422 may include a horizontal driving base 4222 disposed on the frame 100, two horizontal guide rails 4224 arranged side by side on the horizontal driving base 4222, and a cover plate linear driving structure 4226 disposed on the horizontal driving base 4222. The cover plate lifting driving member 424 is slidably disposed on the two horizontal guide rails 4224. The cover plate linear driving structure 4226 is connected to the cover plate lifting driving member 424. Both of the two horizontal guide rails 4224 extend between the cover plate bin structure 410 and the tray storage bin 330. By means of the cover plate linear driving structure 4226, the cover plate lifting driving member 424 and the cover plate adsorption structure 430 thereon can be driven to reciprocate horizontally along the horizontal guide rails 4224 extending between the cover plate bin structure 410 and the tray storage bin 330.

[0051] Moreover, the linear driving structure 4226 of the cover plate includes a horizontal driving motor 42262 provided on the horizontal driving base 4222, and a synchronous belt transmission structure 42264 or a synchronous chain transmission structure connected to the horizontal driving motor 42262. The synchronous belt transmission structure 42264 or the synchronous chain transmission structure is arranged along the extending direction of the horizontal guide rail 4224. Moreover, the lifting driving member 424 of the cover plate may include a lifting base 4242 connected to the synchronous belt transmission structure 42264 or the synchronous chain transmission structure, and a cover plate lifting driving module 4244 provided on the lifting base 4242. The cover plate adsorption structure 430 is arranged at the driving end of the cover plate lifting driving module 4244. The lifting base 4242 is slidably arranged on the two horizontal guide rails 4224. The cover plate adsorption structure 430 is arranged corresponding to both the cover plate bin structure 410 and the tray storage bin 330 up and down. Specifically, one side of the lifting base 4242 may be connected to the transmission belt of the synchronous belt transmission structure 42264 or the transmission chain of the synchronous chain transmission structure, so that the lifting base 4242 can move along with the transmission belt or the transmission chain.

[0052] The operation of the synchronous belt transmission structure 42264 or the synchronous chain transmission structure can be driven by the horizontal driving motor 42262, and the lifting base 4242 of the cover plate lifting driving member 424 can be driven to move along with the synchronous belt transmission structure 42264 or the synchronous chain transmission structure, so that the cover plate lifting driving member 424 and the cover plate adsorption structure 430 can be driven to move together. Thus, the cover plate lifting driving member 424 and the cover plate adsorption structure 430 can reciprocate between the cover plate bin structure 410 and the tray storage bin 330. Moreover, the cover plate adsorption structure 430 can be driven to lift by the cover plate lifting driving module 4244, which is convenient for sucking the cover plates stored in the cover plate bin structure 410 and for placing the sucked cover plates into the tray storage bin 330.
