Abstract

The invention relates to the technical field of battery pole piece processing equipment, in particular to a winding device for a battery cell winding lamination machine. The winding device for the battery cell winding lamination machine comprises a sheet loading assembly, a sheet cutting assembly, a first winding assembly, a second winding assembly and a battery cell unloading assembly, wherein the sheet loading assembly is used for loading a diaphragm sheet; an anode piece and a cathode piece are pasted on two sides of the diaphragm sheet respectively; the sheet cutting assembly is used for cutting a diaphragm of the sheet; the first winding assembly and the second winding assembly are used for clamping the sheet and driving the sheet to rotate to wind the sheet into a battery cell; the battery cell unloading assembly is used for unloading the battery cell; the first winding assembly and the second winding assembly are symmetrically arranged at two sides of a connection line for the sheet loading assembly and the sheet cutting assembly; the first winding assembly and the second winding assembly are located at the rear part of the sheet cutting assembly; and the battery cell unloading assembly is located at the rear parts of the first winding assembly and the second winding assembly. The winding device for the battery cell winding lamination machine is simple in structure, high in work efficiency, stable to run and good in lamination effect.

Description

technical field [0001] The invention relates to the technical field of battery pole piece processing equipment, in particular to a winding device for a battery core winding lamination machine. Background technique [0002] Lithium-ion battery is a new generation of green high-energy battery with excellent performance, and has become one of the focuses of high-tech development. Lithium-ion batteries have the following characteristics: high voltage, high capacity, low consumption, no memory effect, no pollution, small size, small internal resistance, less self-discharge, and more cycles. Because of the above-mentioned characteristics, lithium-ion batteries have been applied to many civilian and military fields such as mobile phones, notebook computers, video cameras, and digital cameras. [0003] In the manufacturing process of lithium batteries, a laminating machine is usually used to assemble the positive and negative electrodes and separators of lithium battery cells into ...

AI Technical Summary

Problems solved by technology

[0004] On the one hand, the stacking table can only pick up one pole piece at a time between the positive and negative poles. The long loading time leads to slow lamination speed. The lamination speed is about 50p / m, and the work efficiency is low. Second, the whole machine The structure is complex, and the stacking table moves back and forth between the positive and negative electrodes and the operation is unstable, resulting in poor lamination effect
