Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery disassembly, in particular to a lithium battery disassembly and fixing device. Background Art

[0002] Recycling of used lithium batteries can be done through professional disassembly and processing techniques.

[0003] When the lithium battery is disassembled, it will be fixed by a fixing device, and then four incisions are formed at the edge of the upper side of the lithium battery by a cutter, and four incisions are formed at the four corners of the lithium battery by a cutter to separate the outer shell of the lithium battery from the internal battery cell. In the specific disassembly process of the lithium battery, we found that after the above-mentioned cutting of the outer shell of the lithium battery to form a total of eight incisions, due to the clamping of the external fixing device during disassembly, the outer shell only has a gap with the internal battery cell, and no larger separation space is generated. Therefore, further disassembly operation completely separates the outer shell from the internal battery cell, resulting in low disassembly efficiency of the lithium battery. For this reason, the present application proposes a lithium battery disassembly and fixing device to solve the above problems. Utility Model Content
