Description

Technical Field

[0001] The utility model relates to the field of battery manufacturing, in particular to a battery tab cutting device. Background Art

[0002] Battery tabs refer to the metal parts of the battery used to connect to electrical devices, usually with positive and negative terminals. These metal parts are usually protruding, flat or have some design features to facilitate connection with the device. In order to adapt to the needs of specific devices or applications, the battery tabs usually need to be cut.

[0003] The existing method of cutting battery tabs is to place the battery on a fixed base so that the battery tabs are located on a lower cutter, and cut the tabs by pressing down with an upper cutter. However, due to the different sizes of batteries, the positions of the tabs on the batteries are also inconsistent. When the battery is placed on a fixed base, there may be a certain distance between the tabs and the lower cutter, resulting in burrs and unevenness on the tabs during cutting, which affects the production quality of the battery and is relatively inconvenient.

[0004] Therefore, a battery tab cutting device is now developed that can adjust the height of the lower cutter to facilitate cutting batteries of different sizes. Utility Model Content
