Overview

The square semi-automatic winding machine is mainly used for precision winding of square lithium-ion battery cells. The working process is as follows: manually guide the positive and negative electrodes into the winding section, stack them with the diaphragm, wind them according to the process requirements, automatically apply the termination tape, and automatically discharge the battery cells.

Product Details

1. Product Introduction

Square semi-automatic winding machineMainly used for precision winding of square lithium-ion battery cells. The working process is as follows: manually guide the positive and negative electrodes into the winding section, stack them with the diaphragm, wind them according to the process requirements, automatically apply the termination tape, and automatically discharge the battery cells.

2.Main Features

●Square semi-automatic winding machineAdopting a double needle structure.

●Manual import of polarizer, automatic winding, automatic needle changing, automatic application of termination tape, and automatic cutting;

●The adhesive tape is applied longitudinally (with the termination tape parallel to the pole ear), ensuring a smooth and precise position without pulling the battery cells tight; Adhesive stability and reliability;

●The needle winding speed can be adjusted;

●Two rolls of diaphragm are actively unwinding, encoder speed control technology, high-precision air proportional valve controls constant tension, and can automatically and smoothly adjust tension during the winding process;

●Equipped with a polar dust removal device;

●End wrapping of polarizer or diaphragm;

●The rolled out battery cells are free from damage, core pulling, and pole misalignment.

●Easy to operate, simple and fast to adjust and replace specifications;

4.Working process and debugging instructions

This device meets the process standards for winding square lithium-ion batteries: the separator is fully wrapped around the negative electrode sheet, and the negative electrode sheet is wrapped around the positive electrode sheet.

Diaphragm pre winding: The use of heating and welding gear cutting technology can save the length of pre rolled diaphragms, avoid diaphragm wire drawing, and prevent convex marks on the appearance of battery cells;

Roll in the negative electrode: manually guide the negative electrode into the winding section;

Roll in the positive electrode: manually guide the positive electrode sheet into the winding section; Winding and turntable flipping transfer station; Cut off the diaphragm, apply terminal adhesive, and cut the material.
