[0041] The purpose of the present invention is to: position the battery pack incoming material trolley; wind and peel off the battery pack bottom plate to expose the module; automatically press out multiple modules in the battery pack onto the incoming material trolley; have a visual addressing and positioning function, and can realize the extrusion of modules of various sizes through the tooling plate of the changing extrusion mechanism.

[0042] The working process of the present invention is briefly described as follows:

[0043] During production, the trolley with the battery pack is moved into the device manually or by AGV. The trolley guide structure 109 is used for limiting the guide when the trolley moves. After the in-place detection sensor 103 detects that the trolley is in place, the trolley clamping cylinder 110 acts to clamp the trolley to prevent the trolley from moving. Then the lifting cylinder 106 extends, and the trolley is lifted and positioned by the lifting positioning mechanism 1. The head of the battery pack bottom plate is manually tilted up by one corner and inserted into the slot of the stripping roller 33 for fixing. Start the equipment, and the motor of the winding drive module 32 rotates, driving the stripping roller 33 to wind and peel. During the stripping process, as the bottom plate is wound on the stripping roller 33, the outer diameter of the stripping roller 33 increases, and the lifting electric cylinder 36 acts to lift the stripping roller to adapt to the change in the outer diameter of the stripping roller 33 to ensure that the product is not squeezed. During the process of the stripping roller 33 winding the bottom plate, the stripping mechanism 3 moves forward on the frame base mechanism 2 due to the winding tension until the bottom plate is completely stripped. After the stripping is completed, the motor of the synchronous drive mechanism 49 drives the gear to drive the extrusion mechanism 4 to move on the frame base mechanism 2, and pushes the stripping mechanism 3 to the equipment loading port. At this time, the stripping mechanism 3 is located at the head of the equipment, exposing the battery pack module extrusion area. The synchronous drive mechanism 49 is actuated, moves the extrusion mechanism 4, moves the visual system 48 to the mark points at the three corners of the battery pack to take pictures, and the visual software calculates the position deviation of the battery pack in the equipment and feeds it back to the PLC. The PLC corrects the module extrusion position according to the position. The extrusion mechanism 4 moves so that the extrusion tooling plate 47 is directly above the module. The extrusion electric cylinder 45 descends, and the speed slows down when approaching the module. The extrusion tooling plate 47 slowly contacts the module, and the module is pressed out of the battery pack box under the action of the extrusion electric cylinder 45. After the module is detached, it falls directly into the incoming material trolley. After the extrusion is completed, the extrusion mechanism 4 is reset to the origin. The lifting cylinder 106 retracts, the lifting frame 104 descends, the trolley positioning pin 105 disengages from the trolley to release the trolley, and the trolley is pulled away manually or by AGV. The end of the bottom plate wound on the stripping roller 33 is fixed to the unwinding column 26 manually using a hook, the equipment is started, the extrusion mechanism 4 drives the stripping mechanism 3 to move, and at the same time, the motor of the winding drive module 32 drives the stripping roller 33 to reverse, so that the bottom plate on the stripping roller 33 is flattened, and the bottom plate is taken away manually after flattening, and the module of the battery pack is taken out.

[0044] For modules of different sizes, matching is performed by replacing the extrusion tooling plate 47. The tooling plate to be replaced is placed on the mold changing table 29, and the extrusion mechanism 4 can be automatically moved to the mold changing table 29 to facilitate the replacement of the extrusion tooling plate 47.

[0045] The battery pack bottom plate is peeled off through the mechanism, and after the module is exposed, the module is automatically pressed out through the extrusion mechanism in conjunction with visual positioning. The automatic peeling of the battery pack water cooling plate is achieved through the trolley positioning mechanism, the peeling mechanism, the extrusion mechanism, etc., and it has flexible functions for different product applications. In actual production, it is efficient and safe, there is no need to remove the structural glue through cumbersome steps, the damage to the battery is minimal, and the recycling yield is greatly improved.
