AI Technical Summary
In the existing technology, during the laser cutting process of lithium battery tabs, smoke and dust affect the laser focus, and the electrode sheet is prone to micro-vibration due to machine vibration or ventilation, which affects the quality of the tab.
The cutting device, which uses a transparent pressure plate connected to a cylinder, achieves centralized negative pressure supply and sequential air path distribution through the design of a pressure valve and a strip-shaped bladder filled with magnetic fluid. This ensures that the electrode sheet is firmly fixed before cutting and that dust is stably removed during the cutting process.
This ensures precise electrode forming dimensions and high cross-sectional quality, reduces the impact of electrode micro-movements, lowers the risk of pipeline blockage, extends the maintenance-free time of the exhaust fan, and achieves stability of the laser optical path and dust removal efficiency.
