Abstract

The invention relates to the technical field of lithium battery production. A lithium battery pole piece laminating device comprises a diaphragm feeding mechanism and a pole piece receiving mechanism,and the diaphragm feeding mechanism is located above the pole piece receiving mechanism. The diaphragm feeding mechanism comprises a mounting base, a material rolling wheel, a guide wheel, an adjusting plate, an adjusting bolt, a pressing air cylinder, a pressing wheel, a roller carrier, a cutter and a cutting air cylinder. The pole piece receiving mechanism comprises a lifting air cylinder, a sliding base, a first linear moving module, a lifting receiving base, a rotating receiving base, a rotating motor and a pressing assembly. The pressing assembly comprises an installation side plate, a pressing motor, a bidirectional lead screw, a vertical plate, a pressing air cylinder, a pressing plate and a second linear moving module. According to the invention, lamination is conducted in the mode that the rotating receiving base swings towards the two sides, and the pole piece placing speed is increased; loosening is prevented, and the flatness of a diaphragm is improved; and the diaphragm is pressed by the pressing plate, so that the wrinkling phenomenon is avoided, and the pressing force is constant.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a lithium battery pole piece stacking device. Background technique [0002] The manufacturing process of the pouch battery core pack is in the middle and front stage of the pouch battery manufacturing process, and it is an indispensable process in the pouch battery production. Since the composition of the core pack is composed of a certain length of diaphragm and multiple positive and negative plates stacked according to a certain logical relationship, each stacking of the diaphragm, positive plate and negative plate is a lamination cycle, and because a core pack It is composed of multiple pole pieces, so each core package requires multiple pole piece lamination cycles, and each core package takes a lot of time to make, so that the core package production process becomes the production capacity of the entire process section. One of the bottlenecks of promotion...
