Description

Technical Field

[0001] The utility model relates to the technical field of battery pole piece processing, in particular to a battery pole piece laminating device. Background Technique

[0002] Battery pole pieces are generally divided into single-crystalline silicon, polycrystalline silicon, and amorphous silicon. Single-crystalline silicon solar cells are the fastest-developed solar cells at present. Their structures and production processes have been finalized, and the products have been widely used in space and on the ground. During the processing and production of battery pole pieces, a laminating device is usually required to perform laminating operations on the formed battery pole pieces.

[0003] In the existing laminating device, generally, a release roller is used to unwind the protective film, and the other end of the protective film is fixed on the laminating seat. Subsequently, the battery pole piece is placed on the laminating seat, and by moving back and forth, the protective film wraps the battery pole piece. Then, the battery pole piece is placed again to stack the battery pole pieces. Since the height of the release roller cannot be adjusted, the protective film becomes slack and gets entangled, or the protective film becomes taut and tears, which affects the working efficiency of the laminating device and reduces the working quality of the laminating device.

[0004] According to a solid-state battery pole piece stacking device provided by the publication number: CN220722803U, which relates to the technical field of battery cell preparation, including a base. The top of the base is provided with a stacking platform driven by a driving mechanism to lift and lower. Both sides of the stacking platform are provided with pole piece racks. The bottom of the pole piece rack is provided with a jacking plate, and the jacking plate is driven by an electric lifting guide rail to lift and lower; the top of the pole piece rack is provided with a reciprocating movable frame, and suction cups for adsorbing pole pieces are fixedly connected to the positions corresponding to both ends of the movable frame and the pole piece rack; the top of the base is rotatably connected with a release drum, and the bottom of the release drum is provided with a protective film limiting member composed of two limiting rollers. The protective film unwound from the release drum falls on the stacking platform through the gap between the two limiting rollers. By using this solid-state battery pole piece stacking device to stack pole pieces, pole piece wear can be avoided, and the stacking efficiency is high.

[0005] According to the above-described stacking device, since the height of the release roller cannot be adjusted, the protective film becomes slack and gets entangled, or the protective film becomes taut and tears, which affects the working efficiency of the laminating device and reduces the working quality of the laminating device. Therefore, we need to propose a battery pole piece laminating device. Summary of the Utility Model
