Description

Automatic unloading equipment for high temperature formation of batteries

technical field

Background technique

Lithium-ion batteries have the advantages of high working voltage, high specific energy, and long cycle life. They are widely used in mobile communication equipment and portable electronic equipment. They are the main development direction of major battery manufacturers.

The lithium-ion battery that has just been manufactured needs to be charged with a small current for the first time. The purpose of charging is to form a layer of SEI film on the surface of the negative electrode, which has a significant impact on the performance of the lithium-ion battery. This is the formation process. The cells need to be charged when they are formed. After the cells are formed, the formed cells need to be removed from the tray, and the voltage should be tested. The unqualified products measured will be removed. At the same time, it is necessary to scan the QR code on the cell to track the cell. After completing the voltage detection, the next process is the second sealing process. The second sealing machine is used to seal the soft pack of the battery cells. Since the battery cells are all facing up when scanning the code and detecting the voltage, that is, the battery cells are not flat. The side of the battery is facing up, but on the second sealing machine, the uneven side of the cell needs to be facing down, so the battery needs to be turned 180° before sending it into the second sealing machine.
