TECHNICAL FIELD

[0001] The utility model relates to lithium battery production technical field especially is related to a laser cutting down waste device. BACKGROUND

[0002] In the production process of battery cell, after the pole piece is coated with material, the pole lug needs to be cut. With the development of industrial technology, the existing pole piece pole lug cutting method is mainly laser cutting. The pole lug is cut by laser cutting, which not only has high cutting efficiency and greatly improves the production efficiency of the pole piece, but also has accurate and controllable cutting trajectory, effectively ensuring the yield of the product.

[0003] However, in the existing pole lug laser cutting process, the pole piece is usually directly emitted with laser on the pole piece on the unwinding table surface during the movement of the unwinding table surface to cut the pole lug. Therefore, the intensity and cutting time of the laser need to be more accurately controlled during the cutting process to avoid burning the worktable surface. In addition, since one side of the pole piece is attached to the unwinding table surface, the dust and waste generated during the cutting process are not easy to collect and are likely to remain on the worktable surface, affecting the pole lug cutting process of the next pole piece. At the same time, the dust adhered to the pole lug on the unwinding table surface will have an adverse effect on the quality of the battery cell produced. SUMMARY

The cutting clearance hole 215 is aligned with the laser mechanism 1, and the cutting clearance hole 215 allows the area of ​​the electrode to be cut to the electrode tab to be cut. The suspension allows the electrode to be laser-cut stably while suspended, making it easier for dust and waste to be collected by the dust hood 213 and hollow roller 212, effectively ensuring the quality of the produced battery cells.
