Through continuous pancake conveying, laser is used to quickly remove active materials on defined coating area on top/bottom side of pancake, accompanied with air suction dedusting to lay bare the current collector and meet tab welding requirements.

1. Top/bottom simultaneous multi-nozzle dedusting, with one-click to switch to different dedusting positioning modes;
2. Time for pancake motion positioning + vacuum suction + de-suction<1.0s，yield rate ≥99.5%;
3. Multiple dedusting and foreign objects removal including fork type brush, vacuum dedusting, FFU, assisting dedusting fan, to ensure no dust residual and high safety
