Intelligent Electrode Tab Forming and Die Cutting Line for Lithium-Ion Battery
1. Equipment Overview
1.1 Equipment Function Overview
This equipment is primarily used for cutting cathode and anode sheets (continuous coating process) in the stacking process of power lithium-ion batteries.
The electrode roll is mounted on the unwinding air shaft of the machine by AGV or manually. The equipment performs automatic unwinding, with an automatic edge alignment system correcting the material during unwinding. Tension is controlled by the tension control system. Before die cutting, a secondary alignment (full web correction) is performed.
After unwinding and buffering, the tab forming station uses a hardware die to punch and form the tabs. A CCD system detects defects on both front and back sides. Then, the material is pulled to the cutting position by the feeding mechanism. After cutting, the sheets are collected in the finished product tray via a conveyor belt. Defective products are automatically rejected into the NG collection box.

1.4 Equipment Highlights
l Unwinding Module: Specially designed air shaft to reduce friction with the roll, enabling quick and easy material change. Automatic unwinding driven by servo motor, using roll diameter algorithm to determine roll usage. When the material is nearly exhausted, the system alarms and stops automatically.
l Feeding Mechanism: Uses patented servo feeding system with ±0.2 mm accuracy.
l Cutting Mechanism: Uses patented non-contact cutting structure, low dust and burrs. The cutter position is adjustable via servo motor according to the sheet size to improve width accuracy.
l Integrated Functions: Optional CCD inspection can be integrated to improve equipment utilization.
l High-Speed Precision Metal Die Punching Mechanism: Servo and eccentric wheel mechanism, fast cutting speed, low noise, stable pressure. Quick die change system with forward/backward, left/right, and angle adjustment. Equipped with independent alignment.
l Tape Bypass Function: When adhesive tape is detected, the cutting knife automatically avoids it, preventing cutter and die damage.
l Die Cooling: Built-in cooling system to reduce blade temperature and prolong die life.
l Precision Granite Cutting Platform: Flatness up to 0.01 mm.
l Stacking Neatness: Servo-driven stacking mode, sheet stacking accuracy ±0.5 mm.
l MES Communication: Two network ports reserved. Hierarchical operation control for convenience.
