In the production process of lithium-ion batteries, lithium-ion battery bag box vacuum sealing machine is a key equipment to ensure battery performance and safety.
The way it works is not complicated. First of all, the bag box equipped with lithium ion batteries is placed on the workbench of the sealing machine, and after the equipment is started, the air in the bag box is quickly extracted through the vacuum pump, so that the inside of the bag box reaches the predetermined vacuum degree. In a vacuum environment, the gas in the bag box is discharged, effectively avoiding problems such as battery oxidation and electrolyte decomposition that may be caused by the presence of air. Then, the heating device of the sealing machine begins to work, heating the sealing part of the bag box to melt its material. Under the action of pressure, the melted parts fuse together and form a tight seal after cooling, thus completing the entire vacuum sealing process.
From the structural point of view, it is mainly composed of vacuum system, heating system, control system and mechanical structure. The vacuum system is responsible for pumping air, and the performance of the vacuum pump directly affects the pumping speed and vacuum degree; The heating system accurately controls the temperature to ensure the sealing quality; The control system is easy to operate, can set vacuum degree, heating time, temperature and other parameters; The mechanical structure ensures the stability and reliability of the equipment operation.
This device has obvious advantages. It can effectively improve the service life and safety of lithium-ion batteries, and reduce the contact between the battery and air through vacuum sealing, reducing the risk of battery failure. At the same time, its efficient work efficiency can meet the needs of large-scale production and improve production capacity. Moreover, the sealing quality is reliable, the sealing performance is good, and the problems such as electrolyte leakage are avoided.
During operation, the personnel must first check the device status to ensure that all components are normal. According to the material and size of the battery bag box, set the appropriate parameters in the control system. When placing the bag box, pay attention to the accurate position, and then start the equipment for vacuum sealing operation. After sealing is completed, take out the product in time and check the sealing quality.
Lithium-ion battery bag box vacuum sealing machine is widely used in all kinds of lithium-ion battery manufacturers, covering consumer electronics, energy storage, electric vehicles and other fields, providing an important guarantee for the production of lithium-ion batteries.
