Description

Technical Field

[0001] The utility model relates to the field of cutting mechanisms, in particular to an R-angle cutting mechanism. Background Art

[0002] Battery tab processing refers to the process of processing the battery tab. In battery production, the tab is an important component of the battery, which connects the positive and negative poles of the battery, enabling the battery to connect to the external circuit and transmit electrical energy.

[0003] When processing the battery's lugs, it is necessary to perform R-angle cutting on the lugs. R-angle cutting can reduce the sharp angle of the lug edge, thereby reducing the possibility of stress concentration. During battery operation, the battery lugs are subjected to changes in current and voltage. Sharp edges will cause stress concentration, increasing the risk of fatigue damage and fracture of the lugs. By performing R-angle cutting, the lug edge can be made smoother, reducing the possibility of stress concentration and improving the durability and reliability of the lug. Sharp edges can easily cause injuries to operators during the production process. By performing R-angle cutting, the lug edge can be made smoother, reducing the risk of accidental injury and improving the safety of production operations.

[0004] In the prior art, when cutting the battery tab, the tab is generally fixed first, and then a cylinder is used to drive the punching cutter to move downward, so that the R-angle punching and cutting of the battery tab can be performed. However, when cutting the tab, both ends of the tab need to be cut. After the cylinder punches one end of the tab, the tab needs to be rotated 180 degrees and then the tab is fixed to punch the other end of the tab, which makes the tab R-angle cutting process more complicated and the cutting efficiency is low.
