Description

A large tab production line for soft pack power batteries

technical field

The utility model relates to the technical field of mechanical automation, in particular to a production line for large tabs of soft pack power batteries.

Background technique

Power tabs are a raw material for soft-pack power battery products. Power tabs are made of two parts, film and metal belt. The traditional method of making power tabs is to use a cutting machine to cut the rolls one by one. The metal strip is cut into pieces to the required size. Manually place the metal pieces one by one on the sheet-arranging mold to arrange the sheets, stick double-sided adhesive tape to fix them, manually stick the upper and lower layers of ear glue, and then stick the film to fix them. Manually take them to the hot pressing machine Welding, after the hot-press welding is completed, manually cut the hot-press welded plates into individual tab materials, manually tear off the film and use it to punch the 4 rounded corners of the metal sheet of the tab, and finally detect the existence of the shipment The problem is that manual operation requires a lot of labor, and it is difficult to ensure the consistency and accuracy of the metal strip spacing when arranging the films, which will waste a lot of excess materials and increase costs, adding unnecessary processes and adding new problems. The surface of the belt is easy to get dirty, and high-quality power lugs cannot be made.
