The liquid injection machine has the advantages of long standing time, full- automatic production and small occupancy area.

Description

technical field [0001] The invention relates to a liquid injection machine for a soft-pack lithium battery, in particular to a liquid injection machine for a soft-pack lithium battery with a long standing time. Background technique [0002] During the production process of the soft pack lithium battery, the electrolyte needs to be injected into the air bag through the liquid injection device, and then the static device is used for vacuum standing, and finally packaged by the packaging device. In the standing step, the length of standing time is very important to the infiltration of the electrolyte and the discharge of air bubbles. If the standing time is short, the quality of the lithium battery will be affected if the infiltration of the electrolyte and the discharge of air bubbles are not complete. If the standing time is too long, the length of the production line will be extended. Moreover, the existing liquid injection machines are generally produced in a linear assembl...

AI Technical Summary

Problems solved by technology

In the standing step, the length of standing time is very important to the infiltration of the electrolyte and the discharge of air bubbles. If the standing time is short, the quality of the lithium battery will be affected if the infiltration of the electrolyte and the discharge of air bubbles are not complete. If the standing time is too long, the length of the production line will be extended. Moreover, the existing liquid injection machines are generally produced in a linear assembly line, and the length of the production line is already very large, resulting in a large floor area of ​​the factory building, which greatly increases the production cost.

In addition, the existing liquid injection machine still needs manual operation in the production process, and has not realized fully automatic production, and the production efficiency is not high
