[0002] Rechargeable batteries generally include nickel-cadmium, nickel-metal hydride and lithium-ion batteries. Cadmium in nickel-cadmium batteries is one of the heavy metal elements strictly controlled by environmental protection. The organic electrolytes in lithium-ion batteries, the alkalis in nickel-cadmium and nickel-metal hydride batteries, and heavy metals such as copper, an auxiliary material for manufacturing batteries, all pose environmental pollution. Recycling of waste rechargeable batteries can not only effectively protect the environment, but also the recycled metal substances can be reused, which can save the waste of resources to a certain extent.

When the cutting part of the cutting mechanism 3 moves for cutting, the traction mechanism 6 can pull the slider 73 of the linkage mechanism 7 to move towards one end of the placement platform 4. Furthermore, the connecting arm 731 on the top of the slider 73 will push the clamping part of the clamping mechanism 2 to move from the movable platform 41 to the fixed platform 42, so that the waste battery fixed in the clamping part of the clamping mechanism 2 can be pulled and split to both sides along the opening of the cutting groove on the shell, enabling the battery core to freely fall onto the movable platform 41 and realize separation from the battery shell. During the movement of the slider 73, it will push the linkage frame 74 to drive the gears inside the gear box 75 to rotate, so that the movable platform 41 can rotate around its rotation axis under the action of the gears inside the gear box 75, so that the battery core falling onto the movable platform 41 can fall into the core collection box 52 along with the flipped movable platform 41, and the battery shell fixed at the clamping part of the clamping mechanism 2 can move to the shell collection box 51 and drop, enabling the device to realize the classified collection of the battery shell and the battery core after disassembling the waste battery, reducing the cumbersome operation brought by manual peeling of the battery shell, improving the disassembly rate of the battery module, and avoiding personal injuries caused by manual peeling of the battery shell.
