Abstract

The embodiment of the invention provides a battery winding device, and relates to the field of battery manufacturing. The battery winding device comprises: a positive pole piece unreeling module which is used for unreeling a positive pole piece; a negative pole piece unwinding module which is used for unwinding a negative pole piece; an upper diaphragm unwinding module which is used for unwinding an upper diaphragm; a lower diaphragm unwinding module which is used for unwinding a lower diaphragm; a turret module which is used for winding the positive pole piece, the negative pole piece, the upper diaphragm and the lower diaphragm; a dust collection module which is used for carrying out electrostatic dust collection on the positive pole piece, the negative pole piece, the upper diaphragm and the lower diaphragm; and a glue outlet rolling module which is used for spraying glue and rolling. According to the embodiment of the invention, the battery performance and safety can be improved; compared with a lamination process, the embodiment of the invention can also reduce waste and has better economic benefits.

Description

technical field [0001] The invention relates to the field of battery manufacturing, in particular to a battery winding device. Background technique [0002] The specific advantages of power batteries, such as high energy density, high cycle life, good safety performance, and flexible design, have enabled them to achieve leapfrog development in the automotive industry. Power batteries are roughly divided into: soft-pack batteries, cylindrical batteries and square batteries. A very critical process in the battery production process is winding or lamination. Among them, lamination is mostly used in soft-pack lithium batteries, and winding is mostly used in cylindrical batteries. Batteries and square batteries. [0003] The stacking process is carried out with a stacking machine, which is to stack the die-cut positive electrode, negative electrode, and separator into a single battery cell, and then go through welding, packaging, liquid injection, chemical formation and other pr...
