Description

Technical Field

[0001] This utility model relates to a soft-pack lithium battery forming equipment, and particularly to a skirt hot pressing shaping mechanism on a soft-pack lithium battery forming equipment. Background Technology

[0002] In the production process of pouch lithium batteries, the skirt of the outer packaging film of the pouch battery needs to be shaped in order to apply UV adhesive to the skirt film. A typical pouch battery is cuboid, and the skirt film is a straight strip corresponding to the perimeter of the pouch battery. During shaping, the skirt that needs to be shaped is simply ironed flat using a straight hot press head. However, when the hot press head is driven and controlled by a conventional cylinder, the pressure holding force cannot be set. If the pressure is too high, it is easy to cause the skirt to char, while if the pressure is too low, the skirt shaping effect will be poor. Summary of the Invention
