BARE CELL FILM WRAPPING DEVICE AND METHOD AND BATTERY PRODUCTION SYSTEM

This application relates to a bare cell film coating apparatus and method, and a battery manufacturing system. The bare cell film coating apparatus includes: a supporting assembly, configured to support a cell assembly, where the cell assembly includes a bare cell and an end cap component connected to the bare cell; and a film coating assembly, configured to apply a coating of an insulation film to the bare cell in the cell assembly placed on the supporting assembly. The film coating assembly includes a mounting bracket and two clamping assemblies configured to clamp the insulation film. Both clamping assemblies are rotatably disposed on the mounting bracket around a rotation axis consistent with a first direction and are spaced out along a second direction. The second direction is perpendicular to the first direction. The insulation film in an unfolded state faces a first end face of the bare cell. The first end face is a surface that is of the bare cell and that is away from the end cap component. The two clamping assemblies are configured to coat the first end face and two first lateral faces of the bare cell with the insulation film in a state of having rotated to a first position toward the first lateral faces of the bare cell. The two first lateral faces intersect the first end face.
