Abstract

The invention relates to a polymer soft-pack lithium battery extrusion vacuum pumping system and a vacuum pumping process thereof, the system comprises a support bottom plate, a smoothing device and apumping device. The smoothing device is installed on the top of the right end of the support bottom plate, and the pumping device is installed on the top of the outer end of the support bottom plate.The smoothing device comprises a smoothing side plate, a smoothing electric sliding block, a smoothing support plate, a smoothing mechanism, a smoothing sliding plate and a smoothing push rod; The smoothing mechanism comprises a smoothing fixing column, a smoothing telescopic column, a telescopic column pushing rod, a smoothing correction plate, a smoothing suction plate, a smoothing sucking disc, a smoothing air pump and a smoothing air pipe. The invention can solve the problems that during vacuum treatment of an existing soft-pack lithium battery, an aluminum-plastic film shakes when beingcut, a vacuumizing tube needs to be manually inserted into the aluminum-plastic film, and air leakage occurs when the aluminum-plastic film is subjected to air extraction.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to an extrusion vacuuming system for a polymer soft-pack lithium battery and a vacuuming process thereof. Background technique [0002] In the production of polymer soft-pack lithium batteries, the battery core and electrolyte need to be chemically processed after being packaged through aluminum-plastic film. The chemical reaction produces a certain amount of gas. These gases are generally concentrated in the space reserved by the aluminum-plastic film. Only the gas in the pouch battery needs to be extracted, so that the pouch battery is in a state close to a vacuum. The vacuum treatment is generally carried out in a semi-automatic way. The existing problems in the vacuum treatment of soft-pack lithium batteries are as follows. The aluminum-plastic film on the soft-pack battery needs to be straightened manually, and the lower end of the aluminum-plastic film canno...
