Description

technical field [0001] The invention relates to the production of a lithium battery, in particular to an automatic production line for liquid injection and pre-sealing of a power soft pack lithium battery. Background technique [0002] In the process of processing the power soft-pack lithium battery, there is a process of liquid injection pre-sealing operation. The existing liquid injection pre-sealing process generally involves manually opening the soft-pack aluminum-plastic film with the battery core and then injecting it. The liquid nozzle is extended into the opened aluminum-plastic film, and then the liquid injection pump is manually opened to inject the electrolyte; the battery filled with the electrolyte is manually transferred to the pre-sealing device; Clamp and heat seal the opening of the battery soft bag, and make the opening of the battery adhere to achieve the purpose of sealing. The production process routes are independent of each other and are connected to ...
