Automatic Aluminum Foil Electrode Slitting Machine 0.2 X 700
Automatic Aluminum Foil Electrode Slitting Machine 0.2 x 700
Battery Electrode Slitting Machine Continuously slit lithium battery electrode coil to required sizes and quality.
To slit cathode / anode electrode (copper foil, aluminum foil with continuous or intermittent lithium ion coating on), the electrode surface without obvious defects like wrinkle or swollen edge.
Slitting process:
Fully automatic closed tension control unwinding, two sets CCD appearance detector to detect defects on both sides(face side and back side) of electrode strip, slit electrode driven by servo motor, two tension measuring guide rollers(upper guide roller and lower guide roller) measure the real-time tension, label defective product and rewind slit electrode strips into coils.
Rewinding speed is independently controlled by servo motor, automatic measure coiling diameter and control coiling tension.
