Automatic Li-ion Battery Electrode Slitting Machine Continuously slit lithium battery electrode coil to required sizes and quality.

The types of electrodes can be slit:

electrode type to slit

Work Principle of the Automatic Electrode Slitting Machine:

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.
