Description

Technical Field

[0002] For electric vehicles, the power battery pack is an important component, which generally consists of a battery pack shell and several battery cells.

[0003] When disassembling a power battery pack, the pole piece core in the battery cell needs to be removed from the battery cell shell. Therefore, the battery cell shell needs to be destroyed, and then the copper and aluminum foil connecting pieces between the shell top cover and the pole piece core need to be cut off to separate the pole piece core from the shell for subsequent recycling. When the battery cell shell is disassembled by the saw blade of the disassembly equipment, metal dust is easily generated. During the cutting process, the cutting position between the battery cell top cover and the pole piece core is not accurate, and the saw blade of the disassembly equipment is likely to damage the pole piece core, thus affecting the subsequent recycling of the pole piece core.

In this embodiment, the conveyor belt 211 drives the battery to move toward the shell placement groove 2201, and the battery pushes open the battery cell shell of the shell placement groove 2201, so that the battery cell shell falls from the shell placement groove 2201 into the shell collection box 281, and the battery cell top cover falling along the guide groove bucket 264 falls into the top cover collection box 283. After the core pushing slide 272 pushes the pole piece core away from the core placement groove 2301, the pole piece core enters the core conveyor belt 282 along the discharge chute bucket 284, and the core conveyor belt 282 transfers the pole piece core to the next process for further processing, so that the various parts of the battery cell are classified and collected, which is convenient for further processing of the battery cell.

[0051] Compared with the prior art, the present disclosure has at least the following advantages:

[0052] 1. The battery cell disassembly equipment 10 mentioned above uses a CNC machine tool 110 to perform a circular cut on the top of the battery along the outer edge of the battery, thereby separating the battery cell top cover from the battery cell shell. The CNC machine tool 110 has high precision in circular cutting the battery cell shell, which reduces the generation of metal dust and avoids damage to the battery cell electrode core, allowing the electrode core to be completely recycled.

[0053] 2. Multiple intermediate plates 1231 divide the installation slot 1201 into multiple placement slots 1202, so that the fixture 120 can clamp multiple battery cells for milling at one time, thereby improving the disassembly speed of the battery cells;

[0054] 3. The sliding clamping plate 1232 can clamp the bulging battery cell under the action of the spring 1233, so that the fixture 120 can clamp battery cells of different sizes, expand the range of clamping battery cells, and improve the efficiency of ring cutting the battery cell shell.

[0055] 4. The battery after ring cutting is transferred to the first pressing mechanism 220 through the conveyor belt mechanism 210. The first pressing mechanism 220 presses the battery cell shell, and the clamping mechanism 240 clamps the battery cell top cover and rises, so that the electrode core connected to the battery cell top cover is separated from the battery cell shell. The clamping mechanism 240 moves the battery cell top cover and the electrode core to the second pressing mechanism 230, and then the cutting mechanism 250 cuts off the connecting piece between the battery cell top cover and the electrode core, so that the battery cell shell, the battery cell top cover and the electrode core are separated and collected, thereby improving the disassembly efficiency of the battery cell.

[0056] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
