A soft-pack lithium battery secondary packaging clamping device and a soft-pack lithium battery processing method

Abstract

The invention relates to a soft-pack lithium battery secondary packaging and clamping device and a soft-pack lithium battery processing method, including a support base plate, a clamping device and a positioning device, and the clamping device is installed on the left side of the upper end surface of the support base plate , the positioning device is located on the right side of the clamping device, and the positioning device is installed on the upper end surface of the supporting base plate; the positioning device includes a positioning electric slider, a positioning telescopic column, a positioning push rod, a positioning connector, a positioning roller, a stretching mechanism and clamping mechanism. The present invention solves the difficulty in adjusting the position of the soft-pack battery existing in the secondary packaging of the existing soft-pack lithium battery, which cannot be locked in all directions for the structure of the soft-pack battery, and the aluminum-plastic film at one end of the soft-pack battery cannot be fixed. Stretching and tightening, unable to automatically smooth the aluminum-plastic film and other problems; it can be realized that the soft-pack lithium battery can be firmly fixed during the secondary packaging, and the aluminum-plastic film at the right end of the soft-pack battery can be straightened and tightened Function.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a secondary packaging and clamping device for a soft-pack lithium battery and a processing method for a soft-pack lithium battery. Background technique [0002] There will be a multi-step packaging process in the production of soft-pack lithium batteries. The packaging is mainly divided into top sealing, one sealing and two sealing. The top sealing is to put the winding core of the battery into the aluminum plastic film. The tabs are heat-sealed with the aluminum-plastic film, and then the aluminum-plastic film at the lower end of the winding core is packaged, and the aluminum-plastic film is packaged after adding electrolyte in the aluminum-plastic film, so that the pouch battery is in a sealed state. After the pouch battery is formed, a certain amount of gas will be generated in the aluminum-plastic film due to the formation. The second seal is to extract the...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a soft-packed lithium battery secondary packaging clamping device and a soft-packed lithium battery processing method, which can solve the position adjustment of the soft-packed lithium battery that exists when the existing soft-packed lithium battery is used for secondary packaging Difficult, unable to lock the structure of the pouch battery in an all-round way, the aluminum-plastic film at one end of the pouch battery cannot be stretched and tightened, and the aluminum-plastic film cannot be automatically smoothed, etc.; it can be realized in the soft-packed lithium The function of firmly fixing the battery during secondary packaging and straightening and tightening the aluminum-plastic film at the right end of the pouch battery is that it is easy to adjust the position of the pouch battery and can be fully adjusted according to the structure of the pouch battery The locking, the aluminum-plastic film at one end of the pouch battery can be stretched and tightened, and the aluminum-plastic film can be automatically smoothed, etc.
