Problems solved by technology

[0003]Existing lithium batteries are mostly rectangular aluminum-cased lithium batteries, but in the production process of aluminum-cased lithium batteries, no matter whether they are formed by opening or sealing the liquid injection hole first According to the method of chemical formation, since the battery will generate gas during the formation of the SEI film during chemical formation, and the gas generated is likely to stay between the pole pieces and the pole pieces, so it is necessary to vacuum seal the lithium battery again. After vacuum pumping and sealing, it must be transported to the folding mechanism for folding
[0004]However, the functions of vacuum pumping, sealing and edge trimming and hemming used in the manufacture of batteries in the market cannot realize integrated production, due to the The process is complicated, and some of the process operations require high precision, because more manpower and time will be required in the production process
In the actual production process, due to human reasons, some of the processes are often not well monitored and judged, and some of the precision requirements are difficult to meet the needs of actual products, which increases equipment costs and wastes production. Working hours affect production efficiency and also affect product quality
