In this way, the second pole piece 330 and the diaphragm 310 can be quickly separated, the separation efficiency is improved, the separation cost is reduced, and the second pole piece 330 cannot be damaged in the process, so that the loss of battery materials in the second pole piece 330 cannot be caused, and the recovery rate of the battery materials can be effectively ensured.

Referring to fig. 5, the pole roller mechanism 160 includes a first driving member 161, a sliding shaft 162, and a roller tube 163. The first driving member 161 is mounted on the frame 110 and is in transmission connection with the sliding shaft 162, and the first driving member 161 is used for driving the sliding shaft 162 to move. The roller 163 is rotatably sleeved outside the sliding shaft 162, the roller 163 can rotate relative to the sliding shaft 162, and the sliding shaft 162 can limit the roller 163. Specifically, the first driving member 161 can drive the roller 163 to displace by the sliding shaft 162, so that the roller 163 rolls relative to the preset separator segment 340, thereby facilitating the detachment of the first pole piece 320 from the preset separator segment 340.

In this embodiment, the frame 110 is provided with a yielding groove 111, and the yielding groove 111 is used for allowing the first pole piece 320 to fall down, so as to facilitate collection and storage of the first pole piece 320.
