Description

Technical Field

[0001] The utility model relates to the technical field of tab crimping, and more specifically to a lithium battery tab crimping device. Background Art

[0002] With the transformation of the global energy structure, new energy vehicles have been increasingly widely used around the world. As a high-energy, long-life, and environmentally friendly battery, lithium batteries have become the core component of new energy vehicles, directly determining the vehicle's range and power performance.

[0003] The tab is an important component in lithium batteries. Its main function is to connect the positive and negative electrodes of the battery to external devices, ensuring the normal operation of the battery to provide power.

[0004] During the production and processing of lithium batteries, the lithium battery tabs need to be crimped. Lithium battery tab crimping refers to the process of connecting the lithium battery tabs to other parts (such as battery cells, circuit boards, etc.). Crimping is a connection technology that connects two or more components together by applying pressure to them.

[0005] The existing lithium battery tab crimping device usually places the lithium battery tab directly on the crimping device for crimping. During the crimping process, since the lithium battery tab is not fixed, it is easy to move, resulting in poor crimping effect; at the same time, since the crimping head of the crimping device is a fixed point, the crimping point is fixed each time, and the lithium battery tab models are different, and the position where each lithium battery tab needs to be crimped is different. When placing the lithium battery tab, it is difficult to place and prepare, and it is not convenient to accurately adjust the crimping point, resulting in inconvenient adjustment of the crimping point. In view of this, we propose a lithium battery tab crimping device. Utility Model Content

At this time, the bottom of the clamping plate 306 is pulled away from the top surface of the crimping table 202 to create a placement space. The lithium battery pole ear that needs to be pressed is placed in it, and the position is adjusted. Then the pull rod 303 is slowly released. At this time, the top plate 305 is acted upon by the downward elastic force of the top spring 304, and cooperates with the gravity of the clamping plate 306 itself, so that the clamping plate 306 presses the lithium battery pole ear downward, so that the lithium battery pole ear is fixed on the crimping table 202. Further, by rotating the threaded rod 205, the crimping table 202 is moved along the slide groove The balance plate 108 is moved in the direction of 208, and then the position of the crimping table 202 is adjusted, that is, the position of the lithium battery pole ear placed on the crimping table 202 is adjusted to ensure more accurate crimping of the crimping point. The hydraulic motor 102 is controlled by the switch 400 to work, and the hydraulic motor 102 drives the hydraulic rod 104 to press downward, and further drives the balance plate 108 to move downward along the two fixed columns 103. The downward movement trajectory of the balance plate 108 is limited by the fixed columns 103, so that the balance plate 108 is relatively stable when moving downward, and will not deviate, and further the lower pressure head 107 under the balance plate 108 is pressed against the lithium battery pole ear on the crimping table 202 to perform the crimping work.
