This equipment requires a stable compressed air supply and a level, rigid floor for safe operation. The cutting process generates fine particulate matter, necessitating containment or local exhaust ventilation.
- Compressed Air Supply: The cutter requires a compressed air supply regulated between 0.5 MPa and 0.8 MPa for pneumatic shaft unwinding and tension control.
- Electrical Supply: The equipment operates on a 220V AC, 50Hz single-phase power source with a rated power of 1.2 kW.
- Material Width Constraint: The cutter is designed for electrode sheets with a maximum width of 300 mm.
- Cutting Tolerance: The cutting burr tolerance is maintained within ±0.05 mm, requiring periodic blade inspection and alignment.
This procedure covers the standard operational sequence for setting up and running a cutting cycle. Always consult the machine manual for detailed safety and maintenance instructions.
Required Equipment: Lithium Battery Electrode Sheet Single Cutter (Model: Atomfair-Cutter367), Compressed air supply (0.5-0.8 MPa), AC 220V/50Hz power source
- Connect utilities
Connect the machine to the appropriate AC 220V/50Hz power source and a compressed air supply regulated to 0.5-0.8 MPa. - Load electrode material
Load the electrode sheet roll onto the pneumatic unwinding shaft, ensuring the material is centered and the shaft is properly secured. - Thread the material
Thread the electrode sheet through the guide rollers and feed it into the cutting mechanism, ensuring it is flat and free of wrinkles. - Set cutting parameters
Use the PLC interface to set the desired cutting length, quantity, and speed within the specified ranges (1-5 m/min). - Start the cutting cycle
Initiate the cutting cycle and monitor the first few cuts to verify cutting quality and dimensional accuracy. - Monitor the operation
Monitor the unwinding tension and cutting process for any signs of slippage, misfeed, or excessive burr formation.
What is the cutting burr tolerance and how does it affect electrode sheet quality?
The Atomfair-Cutter367 maintains a cutting burr tolerance of ±0.005mm, which is critical for preventing internal short circuits and ensuring consistent electrode performance in lithium-ion cells. This precision is achieved through the machine's rigid construction and controlled cutting process, as specified in the technical parameters.
Can the cutter integrate with existing lithium battery production lines for continuous unwinding?
Yes, the cutter supports independent cutting operation with automatic unwinding and automatic constant tension control, allowing flexible integration into production processes. It offers two continuous cutting modes—fixed-length and cursor tracking—with settable front and rear compensation, enabling seamless multi-section cutting without manual intervention.
What are the infrastructure requirements for installing and operating this cutter?
The machine requires a standard AC220V/50Hz power supply with a rated power of 1.2KW, and compressed air at 0.5Mpa to 0.8Mpa for pneumatic shaft unwinding. It has a compact footprint of 1100(L) × 800(W) × 700(H) mm and weighs approximately 240kg, so a stable floor and adequate clearance for material handling are necessary.
The Atomfair-Cutter367 is a PLC-controlled single-sheet electrode cutter for lithium battery production, offering fixed-length and cursor-tracking cutting with automatic tension-controlled unwinding. Its 10N minimum control tension and ±0.005mm burr tolerance support precise electrode processing, but the 300mm width limit and 0.8Mpa compressed air requirement define its operational envelope.
Positive
- High-precision cutting with low burr tolerance: The ±0.005mm cutting burr tolerance ensures clean edges on electrode sheets, which is critical for preventing short circuits and maintaining consistent electrochemical performance in lithium battery cells.
- Flexible cutting modes with automatic tension control: Supports both fixed-length and cursor-tracking cutting modes with settable front/rear compensation, while the pneumatic shaft unwinding with automatic constant tension (minimum 10N) ensures stable material feeding and reduces waste during multi-section processing.
Trade-offs
- Requires compressed air infrastructure: The unwinding system depends on a compressed air supply of 0.5-0.8Mpa, so facilities without a dedicated air compressor or with insufficient pressure capacity will need additional infrastructure investment before operation.
- Limited to 300mm electrode width: The applicable width is capped at 300mm, which restricts the cutter to narrower electrode formats; wider electrode designs used in high-capacity cells would require a different machine or custom modification.
