Problems solved by technology
refer to figure 1 , the traditional bayonet blade 1 is sheet-shaped, and a strip-shaped incision 530 ( figure 2 As shown), when the traditional bayonet blade 1 is pulled out from the air bag 520, the blade surface of the blade is always in contact with the strip cutout 530, which will bring out the electrolyte, causing the electrolyte to splash, contaminate the battery surface, and bring out the electrolyte If the amount is large, it may also cause poor net liquid volume
[0006] Therefore, it is necessary to design a pouch battery air bag piercing device to solve the problem of electrolyte brought out during the traditional bayonet degassing process

The invention provides a piercing device for an air bag of a soft package battery. The piercing device for the air bag of the soft package battery comprises a base and a piercing unit, in some embodiments, the piercing device for the air bag of the soft package battery further comprises a driving unit. The driving unit drives the piercing unit to move in the target direction and pierce the soft package battery air bag. The piercing unit comprises a bayonet. The bayonet comprises a piercing part (knife head). And the piercing part (tool bit) is a cone (cone). Therefore, after the puncture part(tool bit) punctures the air bag, the notch is round, the puncture part (tool bit) of the bayonet is not in contact with the air bag in the pulling-out process, electrolyte cannot be splashed out, andthe problem of poor appearance caused by the fact that the electrolyte punctures the air bag and splashes onto the battery body is effectively reduced.
Description
technical field [0001] The present application relates to the field of lithium-ion battery equipment, in particular to a pricking device for an air bag of a soft pack battery. Background technique [0002] As mobile device technology advances, the demand for rechargeable batteries continues to increase. Low-capacity rechargeable batteries can be used in mobile phones, notebook computers, and portable video cameras, etc., while large-capacity rechargeable batteries can be used in power supplies for electric vehicles, etc. [0003] Lithium-ion power batteries are widely used in the field of electric vehicles. The mainstream lithium-ion power batteries in the industry mainly include three types: square, soft pack and cylindrical. Among them, the soft pack lithium-ion battery has the advantages of high safety, light weight, small battery internal resistance, good cycle performance, strong shape plasticity and simple production process. [0004] The structure of the soft-pack ...
