Abstract

The invention relates to a laser die-cutting clamping device. The laser die-cutting clamping device comprises a support platform with an inner cavity. The support platform comprises a top plate for containing a battery pole piece to be cut. A die-cutting circuit is defined on the top plate. At least one hole penetrating the top plate and communicating with the inner cavity is formed in the top plate along the die-cutting circuit and dust generated when the battery pole piece is cut by lasers along the die-cutting circuit enters the inner cavity of the support platform through the holes. The invention further provides a battery pole piece laser die-cutting method. The laser die-cutting clamping device and the battery pole piece laser die-cutting method have the beneficial effects that the cleanliness of the battery pole piece can be kept, and the yield of an electric core made of the battery pole piece is increased greatly.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of lithium battery manufacturing, in particular to a laser die-cutting clamping device and a battery pole piece laser die-cutting method. [0003] 【Background technique】 [0004] Laser cutting is widely used in the cutting of battery pole pieces in the field of lithium battery manufacturing due to its high cutting precision, fast cutting speed, no scratches on the surface of the workpiece, no mechanical stress on the incision, and no shear burrs. However, when laser cutting the battery pole piece, a large amount of dust will be generated, which will adhere to the battery pole piece and is not easy to remove, resulting in defects such as high self-discharge, short circuit, and poor safety of the battery cell made of the battery pole piece, which greatly affects the quality of the product. Rate. [0005] 【Content of invention】 [0006] In order to overcome the above-mentioned problems that a large amount of du...
