[0002] With the rapid development of the lithium battery industry, large cylindrical batteries have an irreplaceable position due to their obvious advantages in terms of economy, safety and recycling value. Affected by its production process, it is necessary to carry out the negative pressure formation process, that is, to conduct continuous charge and discharge tests on the battery and adjust the battery performance, and to extract the gas generated during the charge and discharge process in time to ensure the stability and consistency of the SEI film. The negative pressure cap used to seal the battery needs to be replaced because it will be affected by its lifespan, so replacing the negative pressure cap is an inevitable problem in battery production. Moreover, because the number of batteries on a single tray has increased in line with production needs, higher requirements are also put forward for the automatic replacement of negative pressure caps.

[0003] Conventional disassembly of negative pressure caps is done manually. Because there are many caps to be disassembled and it is necessary to enter the interior of the equipment for disassembly, the labor cost is high and there are also great safety hazards. In addition, manual disassembly can only be done one at a time. Because the number of negative pressure caps on a single device exceeds 100, the time cost of disassembly is also very high, which will indirectly affect the operating efficiency of the equipment.
