AI Technical Summary
In existing technologies, after laser die-cutting devices cut the electrode sheets, the waste material is not completely separated from the electrode tabs or conveyor belts, which affects production quality.
An air blowing device is installed downstream of the laser generator, using air knives to blow air onto the conveyor belt, forming an electrode conveying channel to ensure effective separation of waste from the electrode. A pressure regulating mechanism is used to create negative and positive pressure zones in different areas to achieve reliable separation of waste.
This effectively avoids the overlap of waste materials with the electrode tabs, improves the quality and efficiency of cell production, and reduces the cost of manual recycling.
