Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery winding machines, in particular to a tab bending device for a large cylindrical lithium battery winding machine. Background Art

[0002] Lithium battery winding machine is an important component of lithium battery production equipment. It has a great impact on the quality and life of the battery. The design of the lithium battery winding machine is an important factor affecting the quality of battery production. Among the winding machines, the tab bending mechanism used for large cylindrical lithium battery winding machines is a more critical component.

[0003] According to the Chinese patent announcement number: CN219123303U, a tab bending device for a large cylindrical lithium battery winding machine is disclosed. The device is provided with a driving mechanism and a smoothing wheel assembly. In order to effectively improve the efficiency and quality of the winding machine in bending the tabs, a deep groove ball bearing is used in conjunction with the smoothing wheel body to fold the tabs. During winding, the smoothing wheel body rotates synchronously and does not produce hard friction with the tabs, ensuring high-efficiency and high-precision production. In this technical solution, the position of the smoothing wheel support shaft on the smoothing wheel support block is fixed, and it is difficult for personnel to adjust the fixed position of the smoothing wheel support shaft, resulting in the smoothing wheel body being inconvenient for bending lithium battery tabs of different specifications. There are certain limitations in use. For this reason, we propose a tab bending device for a large cylindrical lithium battery winding machine. Utility Model Content
