This machine requires a 3-phase 380V/50A power supply and compressed air at 0.5 MPa and 400 L/h. Electrode slitting generates fine conductive dust, mandating an onboard dust collection system rated ≥1200 m³/h with ≥99% purification.
- Electrical Supply Constraint: A dedicated 3-phase 380V/50A circuit with proper overcurrent protection and grounding is required.
- Compressed Air Constraint: Compressed air supply must maintain 0.5 MPa pressure at 400 L/h for the pneumatic expanding shaft and tension control system.
- Dust Collection Constraint: The integral dust collector must operate at a minimum air volume of 1200 m³/h to maintain a purification efficiency of ≥99%.
- Floor Loading Constraint: The machine weighs 4 tons and requires a reinforced floor capable of supporting the static and dynamic load.
This procedure describes initialization, setup, and slitting operation for Li-ion battery electrodes. Follow all electrical and pneumatic safety protocols before starting.
- Connect utilities
Connect the machine to a 3-phase 380V/50A power source and compressed air supply at 0.5 MPa with 400 L/h flow rate. - Load electrode roll
Load the electrode roll onto the pneumatic expanding unwind shaft and secure it to prevent axial movement. - Set slitting parameters
Set the slitting width, speed (0–60 m/min), and unwind tension (0–300 N) via the HMI touchscreen interface. - Activate edge correction
Activate the automatic edge correction system and verify it maintains the web within ±75 mm with ±0.1 mm accuracy. - Start slitting process
Start the drive motor and monitor the slitting process, ensuring burr remains ≤10 μm vertical and ≤13 μm horizontal. - Unload slit rolls
After completion, stop the machine and remove the slit electrode rolls from the Nishimura type differential rewind shafts.
How does the Atomfair-ASM-620 achieve a slitting accuracy of ≤±0.05 mm while maintaining burr levels below 10 μm vertical and 13 μm horizontal across electrode thicknesses from 5 to 300 μm?
The machine uses a Nishimura type disc cutter set and floating cutter slitting to minimize mechanical play and ensure consistent edge quality. The specification confirms burr control of vertical ≤10 μm and horizontal ≤13 μm, with slitting accuracy ≤±0.05 mm across the full thickness range of 5–300 μm. The automatic closed-loop tension system (0–300 N) and edge correction accuracy of ±0.1 mm further support this precision.
What are the utility requirements for installing the Atomfair-ASM-620 in a battery electrode slitting facility?
The machine requires a 3-phase 380V/50A/50Hz power supply with 5 kW total power, and compressed air at 0.5 MPa with a consumption rate of 400 L/h. The dust collection system needs a capacity of 1200 m³/h with ≥99% purification efficiency. The floor must support a 4 T weight and the unit's dimensions of 850 mm × 600 mm × 1200 mm.
What precautions are needed when operating the automatic winding system on the Atomfair-ASM-620 with electrode rolls up to 600 mm diameter and 500 kg load?
The unwind shaft is a pneumatic expanding shaft with a load capacity of 500 kg and a maximum roll diameter of 600 mm. Operators must ensure the automatic closed-loop tension system (0–300 N) is calibrated to prevent foil breakage or slippage during unwinding. The rewind uniformity of ±0.5 mm requires proper setup of the Nishimura type differential shaft to maintain consistent winding tension and edge alignment.
The Atomfair-ASM-620 automatic slitting machine combines high slitting precision (≤±0.05 mm) with full PLC automation for efficient Li-ion battery electrode processing, but its 4-ton weight and need for 3-phase power and compressed air impose significant facility requirements.
Positive
- High precision slitting ≤±0.05 mm: The machine achieves slitting accuracy of ≤±0.05 mm and burr control of ≤10 μm vertical and ≤13 μm horizontal, critical for Li-ion battery electrode quality.
- Full PLC automation with HMI: The PLC-controlled system with user-friendly HMI enables fully automated operation, reducing labor cost and improving consistency for high-volume electrode slitting.
Trade-offs
- Heavy 4-ton machine mass: The 4-ton weight requires reinforced flooring and specialized equipment for transport and installation, limiting deployment flexibility in some labs.
- Requires 3-phase power and compressed air: The machine demands a 5 kW, 3-phase 380V/50A/50Hz power supply and 400 L/h compressed air at 0.5 MPa, necessitating dedicated infrastructure.
