Cylindrical Cell Winding Machine 300 r/min ATOMFAIR®

Operational constraints for the Atomfair-SACW-619 include a required compressed air supply of 0.5–0.7 MPa and a 1 kW power supply. The machine is designed for semi-automatic winding of cylindrical lithium-ion cells within specified cell dimensions and winding precision limits.

• Pneumatic Supply Requirement: The machine requires a compressed air supply of 0.5–0.7 MPa for pneumatic components to function correctly.
• Electrical Power Requirement: The machine operates on a 1 kW power supply, which must be properly grounded and rated for the local electrical code.
• Cell Dimension Compatibility: The winding system is compatible with cylindrical cells having a diameter of 17–32 mm and a length of 25–70 mm.
• Winding Precision Tolerance: The winding alignment precision is maintained within ±0.5 mm to ensure consistent cell quality.

This procedure outlines the safe and correct steps to set up and operate the Atomfair-SACW-619 for semi-automatic winding of cylindrical lithium-ion cells. It covers initial setup, parameter configuration, and the winding process.

Required Equipment: Atomfair-SACW-619 Semi-Automatic Cylindrical Winding Machine, Touch screen HMI control panel, Automatic tape dispenser

1. Connect utilities
   Connect the machine to a 1 kW power supply and a compressed air source regulated to 0.5–0.7 MPa.
2. Load separator and electrodes
   Load the separator roll onto the shaft and position the sheet electrodes in the adjustable guide, ensuring the electrode width is within the guide's adjustable range.
3. Set winding parameters
   Set the winding speed, cell length, and other parameters on the touch screen HMI, ensuring the cell dimensions are within the machine's specified range.
4. Thread the separator
   Thread the separator through the winding needle and guide rollers, ensuring proper tension is applied by the constant tension system.
5. Initiate automatic winding
   Start the automatic winding cycle via the HMI; the machine will automatically feed the separator, wind the cell, and cut the separator at the end of the cycle.
6. Apply tape manually
   After the winding cycle stops, manually apply tape to secure the cell end using the automatic tape dispenser.
7. Remove the finished cell
   Remove the finished cell from the winding needle and inspect the alignment to ensure it meets the ≤0.5 mm precision specification.

The Atomfair-SACW-619 semi-automatic cylindrical winding machine provides a practical upgrade from manual winding for R&D and small-batch production of cylindrical lithium-ion cells, with constant tension separator feeding and automatic separator cutting that improve winding uniformity and reduce operator variability. Its adjustable electrode guide width and cell size range of 17–32 mm diameter and 25–70 mm length offer flexibility for diverse electrode formats, though the semi-automatic design requires manual tape application and a compressed air supply of 0.5–0.7 MPa, and the 800 kg weight necessitates dedicated lab space.

Positive

• Constant tension separator feeding: Maintains consistent separator tension during winding, which directly improves cell winding regularity and reduces defects in cylindrical lithium-ion cells, a critical factor for lab-scale process development.
• Adjustable electrode guide width: The guide width is adjustable to accommodate a wide range of electrode widths, enabling flexible use across different cell designs and R&D experiments without requiring dedicated tooling changes.

Trade-offs

• Manual tape application step: The machine automates separator feeding, winding, and cutting, but tape application is manual (with an automatic dispenser), which introduces operator dependency and may reduce throughput in continuous production settings.
• Requires compressed air supply: Operation depends on a compressed air source at 0.5–0.7 MPa, so the lab must have adequate air infrastructure; without it, the machine cannot function, adding an installation and utility requirement.
