Lithium battery soft package and hard package

lithium battery is divided into soft pack and hard pack two forms. The main difference between the two is the material of the lithium battery shell. The flexible packaging battery is a liquid lithium ion battery with a layer of polymer shell, which is softer than the aluminum shell lithium battery pack.

The key materials used in soft-packed lithium batteries-cathode materials, anode materials and separators-are not much different from the traditional steel-aluminum-shell lithium batteries. The biggest difference lies in the flexible packaging material (aluminum-plastic composite film). This is the most critical and technically difficult material in soft-packed lithium batteries.

Mobile phone lithium battery

in fact, soft pack lithium battery is no stranger in our life. In addition to the application in power batteries, energy storage batteries, the most common used in the battery components of 3C electronic products. For example, the application is integrated in the mobile phone and cannot be disassembled without permission.

when the soft-pack lithium battery is manufactured, it is necessary to trim, fold, and glue the shell polymer material to make the docking part more tightly and not cause leakage of liquid inside the lithium battery.

Fully automatic double folding edge dispensing equipment

dickwell's remote IO module has been deeply involved in the lithium-electric industry for many years, providing a complete remote IO solution for lithium-electric equipment.

For example, the fully automatic double folding equipment developed by a well-known lithium battery equipment manufacturer is mainly used for the double folding molding process of soft-packed lithium batteries, including trimming, double folding, dispensing, ironing and other processes. The device uses Dulkwell's EX series of expandable remote IO modules.

Equipment basic structure:

the

feeds through the mechanical arm, enters each station to complete the folding and dispensing process of the lithium battery of the mobile phone in turn, enters the blanking area to load the plate and enters the AGV to enter the next process.

1. The control part mainly adopts KV8000 series PLC and expands the EtherCAT master station module.

2. Control servo motion and Deckwell EX series plug-in remote IO module through EtherCAT bus

3. Communication with manipulator through PLC ontology EtherNet/IP protocol

4. The equipment has more points and is divided into three IO slave stations. Two of the stations are: EtherCAT adapter 2 × 32DI 2 × 32DO, and the other station is: EtherCAT adapter 1 × 32DI 1 × 32DO.

The device has more cylinders, mainly through the remote IO input module to collect magnetic switch and photoelectric switch signal, and through the output module to control the solenoid valve to control the cylinder action.
