After the cylindrical lithium battery is filled, the electrolyte of the lithium battery shell always leaves the electrolyte, and the process of filling the liquid to the seal is in a low-temperature and dry environment. The electrolyte on the shell is easy to crystallize, and the electrolyte crystallizes lightly on the shell. The battery case is rusted due to the corrosion of the electrolyte; in other words, the seal is not tight due to crystalline crystal particles, which causes the battery to leak, which poses a serious safety hazard. Therefore, in order to ensure that the electrolyte of the lithium battery is free from residual electrolyte or Five electrolyte crystals. Most manufacturers usually use a cotton swab to wipe the battery case.

This operation method can remove some electrolyte and electrolyte crystals, but it cannot completely remove the electrolyte and electrolyte crystals, and manually wipe the lithium battery case. Low, the manipulator wipes the lid of the lithium battery case, and it is easy to bump or damage the ears, which will adversely affect the subsequent laser welding process.

An integrated lithium battery production line is provided, which is composed of an oven, a cooling glove box, a liquid injection glove box, a buffer glove box, a squeeze (static) vacuum box, a sealed glove box, and a discharge vacuum box.

Advantages: The oven and the glove box are seamlessly connected. After baking, the battery core is always kept in the glove box environment without water and oxygen. The entire production line includes a cooling glove box, which has a fast cooling speed and low cost, ensuring that the battery cells are baked from filling to filling, and the sealing process is operated in a controlled anhydrous and oxygen-free environment, providing the most solid protection for the quality of the battery. It can realize the automatic production of batteries, greatly improve production efficiency, save human capital, and configure the MES manufacturing execution system, which enables information production customers to avoid the need to build a drying room and purchase a rotary dehumidification system, saving investment costs and operating costs.

Lithium battery production lines avoid the impact of the appearance and sealing effect of the lithium battery due to the electrolyte or the crystallization of the electrolyte, and will not damage the shell of the lithium battery, which will help improve the production efficiency and product quality of the product.
