The operator also removes the screws magnetically adsorbed on the replaceable screwdriver head 13 to avoid affecting the removal of the next group of screws. After all the screws are removed, the battery pack moves to the bottom of the top cover removal mechanism 20, and the third servo electric cylinder 24 is controlled to push the suction cup mounting plate 25 down. The suction cup array 26 adsorbs the top cover of the battery pack, and then the third servo electric cylinder 24 can be controlled to drive the suction cup mounting plate 25 together with the suction cup array 26 and the battery pack top cover to rise, and the linear drive 22 can be controlled to drive the connecting fixing frame 23 to move forward, and the battery pack top cover is transferred to the top of the receiving platform 27, and then the suction cup array 26 is released from the adsorption of the battery pack top cover, and the battery pack top cover can be placed on the receiving platform 27. After a certain number of stacking, it is convenient for workers to carry it in a centralized manner. The battery pack with the top cover removed continues to be conveyed to the right by the conveyor belt 2 to the battery module disassembly station. In summary, this device can automatically remove the screws used to fix the top cover and the battery pack body of the battery pack through the cooperation of the automatic screw removal device 3 and the guide anti-bias device 16, and can automatically remove the top cover of the battery pack through the top cover removal mechanism 20, thereby improving the efficiency of battery disassembly and reducing the workload of workers.
