Automatic Die Cutting Machine for Lithium Battery Electrode with ±0.05mm Slitting Width Precision and Z-stacking Continuous Coating

The Automatic Die Cutting Machine is designed for continuous die cutting and forming of cathode and anode electrodes used in lithium-ion stacked batteries.

The machine supports rolled electrode feeding, automatic unwinding and correction, adjustable tension, continuous punching and automatic electrode handling. Different cutter molds can be provided according to customer requirements to produce battery electrodes in different shapes and sizes.

A precision punching system and synchronous PET film feeding system are used to achieve automatic punching and forming of rolled electrode materials, including tab structures.

• Designed for lithium-ion battery electrode die cutting
• Suitable for cathode and anode electrodes
• Continuous punching of rolled electrode materials
• Automatic electrode unwinding and correction
• Adjustable feeding tension
• Automatic waste material collection
• Servo motor driven die-cutting system
• Adjustable cutting amount and cutting speed
• Automatic electrode handling by robotic arm
• Quick cutter installation and replacement
• PET film carrier feeding system
• Small burrs and reduced powder loss
• Manual and automatic operation modes
• HMI control with fault display and alarm functions

The equipment is specifically designed for the pre-stacking process and uses a precision punching system to help control burrs and powder shedding from electrode sheets.

The machine uses a roll feeding mechanism. The electrode is fixed using an air expanding shaft, while rolling bearings allow convenient installation and material replacement.

Motor-driven automatic unwinding and precision correction help position the electrode accurately during feeding. High-precision sensors are used to correct feeding errors.

The die-cutting mechanism is driven by a servo motor and guided by linear bearings. The cutting die moves vertically to punch and form the electrode into the required shape.

The cutter can be quickly installed and replaced. A safety grating is also installed at the cutting workstation.

After die cutting, the electrode handling mechanism uses a servo motor and precision ball screw for accurate positioning. Suction cups are used to transport the electrodes while helping protect the electrode material.

The machine uses an HMI control system with adjustable speed parameters, fault location display, manual and automatic operation modes, fault alarms and three-color warning lights.

The software includes interlocking functions between different operating units to help prevent incorrect operation.
