Description

Technical Field

[0001] The invention relates to the technical field of lithium battery connecting piece processing, and in particular to a lithium battery shell cover connecting piece manufacturing device and a manufacturing process. Background Art

[0002] In the manufacturing process of lithium batteries, the processing of connecting plates is a key step, especially in the drilling operation. As an important part of the battery assembly, the connecting plate is usually made of metal materials and is used for the structural stability and electrical connection of the battery shell.

[0003] Publication number "CN218611404U" discloses a lithium battery connector stamping die, which is equipped with a rebounder and a spring pressure rod. When stamping, the hydraulic rod is turned on to press the stamping block downward. When the bottom of the stamping block continuously generates pressure on the support plate, the entire support plate will continue to move downward. At this time, the stamping groove and the stamping bottom plate will stamp the battery connector into shape, and then the stamping block will be lifted up. Under the action of the rebounder and the spring pressure rod, the support plate will also be reset. The stamped connector will be brought out of the stamping die through the joint action, avoiding the danger of workers taking it directly with their hands, and the next connector can be stamped quickly.

[0004] In actual use, when using a mechanical drill to drill holes, metal chips generated by cutting may be scattered in the working area, causing secondary pollution of the equipment and potential mechanical failure. The disorderly scattering of metal chips may also scratch or damage the surface of the completed connecting piece, affecting the overall quality and appearance of the product. In addition, the accumulation of metal chips during the cutting process may also increase the difficulty and frequency of equipment maintenance, thereby reducing production efficiency and increasing operating costs.
