[0001] The invention belongs to the technical field of battery box film coating, and in particular relates to a film pressing leather wheel mechanism for battery box film coating. Background Art

[0002] After the processing of the lead-acid battery box is completed, a protective film will be applied to the surface of the battery box; this can prevent the lead-acid battery box from being scratched during subsequent transportation and assembly. In the traditional battery production industry, the coating operation of the pole groups coming out of the stacked plates is generally completed on a simple platform and relies on manual coating. Generally, the rectangular structure of the battery is coated on four or six sides. This traditional operation method has low work efficiency, high labor intensity, and cumbersome operation. The automatic coating equipment and methods currently used in the market generally automatically coat the battery box for at least one circle, but the structure and process are relatively complicated, which reduces the process operation efficiency and increases the equipment cost.
