Description

Technical Field

[0001] The utility model relates to the technical field of disassembly devices, in particular to a self-adaptive and efficient disassembly device for a lithium battery shell. Background Art

[0002] The commonly used lithium-ion power battery is a very important battery system, which is mainly composed of shell hardware, positive and negative electrodes, diaphragms and electrolytes. Since most of its internal materials are non-degradable, random disposal will cause great damage to the environment, especially the internal electrolyte, which is highly corrosive to the environment. Therefore, the recycling of lithium-ion batteries is very important. If lithium batteries are to be recycled, they must first be disassembled. When disassembling lithium batteries, it is necessary to cut off a section of the lithium battery with an electrode head (i.e., the top cover), and then take the battery cell out of the lithium battery shell. The existing lithium battery shell disassembly device is in progress. When disassembling lithium batteries, a cutter is usually used to disassemble the battery shell. However, due to the different battery models and different diameters, the traditional disassembly device needs to first clamp and position the shell, and then cut off the end of the shell. The travel distance of the cutter is constant, but when disassembling lithium batteries of different diameters, if the battery diameter is the smallest, a certain amount of equipment idling is required before the cutter contacts the lithium battery, thereby reducing the working efficiency of the device. It is impossible to ensure that the distance between the cutter and the battery cross section is constant before displacement, which makes the device prone to idling, reducing its disassembly efficiency. Utility Model Content
