A vacuum pumping robot for soft package lithium battery packaging

Abstract

The invention relates to a vacuum pumping robot for packaging a soft-packed lithium battery, comprising a support base plate, a clamping mechanism, a smoothing device and an extracting device. On the top of the right end of the support base plate, the extraction device is installed on the top of the outer end of the support base plate; the clamping mechanism includes two clamping claws, a clamping angle push rod, a clamping electric slider, a clamping vertical plate, a clamping Transfer frame and transfer rollers. The invention can solve the problem that the aluminum-plastic film on the soft-pack battery needs to be straightened manually when the vacuum treatment is performed on the existing soft-pack lithium battery, shaking occurs when the aluminum-plastic film is cut, and the cutting size of the aluminum-plastic film is difficult to control and requires manual labor. Insert the vacuum tube into the aluminum-plastic film, and the aluminum-plastic film will leak when pumping air.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a vacuum pumping robot for packaging a soft-packed lithium battery. Background technique [0002] In the production of soft-packed lithium batteries, the battery core and electrolyte are packaged through aluminum-plastic film and then they need to be chemically treated. After the soft-pack battery is formed, a chemical reaction will occur between the battery core and the electrolyte in the aluminum-plastic film. A certain amount of gas is generated, and these gases are generally concentrated in the space reserved by the aluminum-plastic film. It is only necessary to pump out the gas in the pouch battery so that the pouch battery is in a state of near vacuum. The processing is generally carried out in a semi-automatic manner. The existing problems in the vacuum treatment of soft-pack lithium batteries are as follows. The aluminum-plastic film on the soft-pack ba...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a vacuum pumping robot for the packaging of soft-packed lithium batteries, which can solve the problem that the aluminum-plastic film on the soft-packed battery needs to be manually straightened and the aluminum-plastic film existing when the existing soft-packed lithium battery is vacuum treated. There will be shaking when the film is cut, it is difficult to control the cutting size of the aluminum-plastic film, it is necessary to manually insert the vacuum tube into the aluminum-plastic film, and the aluminum-plastic film will leak when the air is pumped; it can realize the right end of the soft pack battery. The aluminum-plastic film can be cut and vacuum-processed, and the aluminum-plastic film on the pouch battery can be straightened mechanized, the aluminum-plastic film will not shake when cutting, the cutting size of the aluminum-plastic film can be easily controlled, and the vacuum tube can be automatically inserted into the The advantages of aluminum-plastic film and aluminum-plastic film will not leak when pumping air
