Description

Technical Field

[0001] The utility model relates to the technical field of soft-pack battery tabs, in particular to an automatic shaping and cutting device for soft-pack battery tabs. Background Art

[0002] The tabs are usually made of metal sheets and are a component of soft-pack lithium-ion battery products. Batteries are divided into positive and negative electrodes. Tabs are metal conductors that lead the positive and negative electrodes out of the battery core. In layman's terms, the tabs of the positive and negative electrodes of the battery are the contact points during charging and discharging. In the production process of lithium batteries, in order to maintain battery performance, the tabs of the battery need to be shaped and cut.

[0003] In existing factory production, the tabs are usually shaped and then cut by cutting equipment. The two processes cannot be completed at the same time, which easily reduces the production and processing efficiency and increases the cost of tooling. In addition, on existing production lines, tab processing usually has two methods: robotic arm and manual loading and unloading. The cost of loading and unloading by robotic arm is relatively high, while the efficiency of manual loading and unloading is relatively low and there are certain safety hazards.
