Laser electrode cleaning machine is positioned by the continuous belt running of the electrode piece, combined with the dust removal system optimized by hydrodynamics simulation, and uses high-speed laser scanning to quickly remove the coating film on the front and back sides of the anode plate of lithium battery, exposing the metal conductive current collector in the middle, which is convenient for the requirements of tab welding in the later process.
·High cleaning efficiency, single station efficiency > 15 ppm.
·The cleaning quality is good, and the residue and pinhole are less than 0.10 mm.
·The dimensional accuracy is accurate, and the dimensional error of groove position is less than 0.15 mm.
Automatic deviation correction rewinding and unwinding mechanism to ensure unwinding balance
·Real-time detection of pole piece edge deviation before cleaning, and real-time compensation of laser path to ensure cleaning area
·Adapt to the pole piece before and after rolling, the cleaning effect will not be affected.
