Introduction to the functions and principles of the equipment:
Lithium metal anode making machine is applicable to the preparation and molding/shaping of lithium metal anode. It can perform lithium metal strip fixed-length cutting and copper strip fixed-length tab cutting, so as to realize (lithium electrode sheet+copper tab) pressing and making anode electrode process.
This device completes the pole film production process of laminated lithium ion battery, plastic shapes the pole film and cuts it into slices, and then the pole slice is automatically collected. Manual winding installed on the air expansion shaft of the equipment, the equipment automatically winding, the correction mechanism for the winding process, and control the tension of the electrode sheet through the tension control system, the servo motor traction mechanism will transport the electrode sheet to the hardware mold for the pole ear cutting station with the continuous pole cutting into a single electrode sheet sent to the material box for collection.
