[0008] Compared with the prior art, the present invention has the following beneficial effects: the tray can automatically collect the plates, saving labor, and has high control accuracy. The front and rear trays are basically connected without gaps, so there is no accident of falling plates in the process of changing trays, which ensures the yield rate of the plates and improves the collection efficiency of the plates. In addition, when the front tray is full of plates and the rear tray is replaced to connect the plates, the two narrow conveyor belts and the wide conveyor belt drive the two trays to run at double speed for 1 second. After the front tray is quickly displaced, the rear tray follows closely and quickly displaces the length of the area with a short length of the long adsorption device. During this time period, the area with a short length of the long adsorption device no longer adsorbs the plates. The position where the plates fall in the tray is moved back by the length of the area with a short length of the long adsorption device, so that the position where the rear tray connects to the plates no longer receives the plates repeatedly, so that the plates are received and arranged in an orderly manner, and the plates are no longer damaged, which greatly improves the yield rate of the plates.

[0016] A long adsorption device is arranged above the tray electrode connection device. A long length zone and a short length zone are arranged on the long adsorption device, and the vacuum air paths are respectively controlled by two solenoid valves.

[0017] Operation control process: Press the switch, the solenoid valve is turned on, the bracket lifting cylinder Ⅰ drives the bracket to rise, and the reduction motor Ⅰ starts to drive the left and right conveyor chains to run at a low speed. The proximity switch Ⅰ detects that the push plate is in the initial position. When the reduction motor Ⅰ runs and drives the pallet to descend to the bracket, the laser diffuse reflection sensor Ⅰ detects the pallet and sends a signal to the reduction motor Ⅰ, which decelerates and stops, and the pallet completely detaches from the pallet storage rack; the other solenoid valve is turned on, and the magnetically coupled rodless cylinder drives the push plate to push the pallet out of the bracket until it is pushed to the receiving bracket. At this time, the receiving bracket is in an elevated state (there is no pallet on the two narrow conveyor belts at this time or the pallet continues to run without blocking the laser sensor Ⅲ). After the laser sensor Ⅰ detects the pallet, the other solenoid valve is reversely connected, and the magnetically coupled rodless cylinder is withdrawn; when the laser sensor Ⅳ is not blocked, the third solenoid valve is turned on, the receiving bracket descends, and the pallet is placed on the two narrow conveyor belts and transported backwards. The front and rear pallets are docked together. At this time, the rear pallet blocks the laser sensor Ⅱ, laser sensor Ⅲ and laser sensor Ⅳ; when the rear pallet continues to run until it does not block the laser sensor Ⅱ, the two narrow conveyor belts and the wide conveyor belt simultaneously drive the front The rear two trays double the speed within one second to accelerate the distance of the short zone of the long adsorption device. In this embodiment, the front and rear trays run 75 mm in one second (the original speed is 35 mm per second). At the same time, the solenoid valve of the short zone of the long adsorption device is opened for one second, and the electrode plate is no longer adsorbed, so that the position of the dropped electrode plate is moved back to the distance of the short zone of the long adsorption device. In this embodiment, it moves back 75 mm, and the short zones of the two long adsorption devices restore the vacuum state; at the same time, the proximity switch Ⅰ detects that the initial position of the push plate is in place, and the reduction motor Ⅰ runs, driving the tray to descend to the bracket. After the laser diffuse reflection sensor Ⅰ detects the tray, the reduction motor Ⅰ slows down and stops, and the tray is completely separated from the tray storage rack; when the tray continues to run without blocking the laser sensor Ⅲ, the receiving tray rises and the magnetically coupled rodless cylinder drives the push plate to push the tray out of the bracket until it is pushed to the receiving tray. After the laser sensor Ⅰ detects the tray, the magnetically coupled rodless cylinder withdraws and repeats the above steps.

[0018] Of course, the present invention has many other embodiments. Without violating the spirit and essence of the present invention, technicians familiar with the field can make corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should be regarded as improvements of equivalent technologies and belong to the protection scope of the claims of the present invention.
