Manual Battery Cell Winding Machine MW-358 ATOMFAIR®

This machine is intended for manual winding of aluminum foil flexible packaging battery cells and requires a stable 220V/50Hz power supply. Operation is limited to cylindrical cells within Φ30 mm, and the machine must be placed on a level, stable surface to ensure winding precision.

• Cell Dimension Constraint: The winding process is limited to cylindrical cells with a maximum diameter of 30 mm.
• Power Supply Requirement: The machine requires a 220V/50Hz power source and consumes 40W during operation.
• Mechanical Stability: The machine must be placed on a stable, level surface to maintain winding accuracy and prevent operational vibration.

This procedure describes the safe setup and operation of the manual winding machine for producing battery cells. Follow the steps in order to ensure correct winding tension and alignment.

Required Equipment: Manual winding machine (Atomfair-MW-358), Positive and negative electrode strips, Separator material

1. Prepare the machine
   Place the machine on a stable, level surface and connect it to a 220V/50Hz power outlet.
2. Adjust the winding guide plate
   Adjust the upper, lower, left, right, front, and rear positions of the winding guide plate to match the electrode and separator widths.
3. Set the rotational speed
   Set the rotational speed to the desired value within the 0-170 rpm range using the stepless speed regulator.
4. Load the electrode and separator
   Feed the positive electrode, separator, and negative electrode into the winding needle, ensuring proper alignment and tension.
5. Start the winding process
   Start the machine and manually rotate the handle to wind the electrodes and separator into a cell, maintaining even tension.
6. Reverse if necessary
   If winding defects are observed, use the reverse rotation function to unwind and rewind the cell as needed.
7. Remove the wound cell
   Stop the machine and carefully remove the wound cell from the winding needle, then inspect for proper alignment and tightness.

The Atomfair-MW-358 manual winding machine is a compact, benchtop unit designed for the manual winding of aluminum foil flexible packaging battery cells, offering adjustable guide plate positioning, auxiliary support wheels, and stepless speed control up to 170 rpm for cylindrical cells within Φ30 mm.

Positive

• Adjustable guide plate for precision: The upper, lower, left, right, front, and rear positions of the winding guide plate are adjustable, enabling precise alignment of electrodes and separator during manual winding, which is critical for cell quality.
• Stepless speed and bidirectional control: Rotational speed is continuously adjustable from 0 to 170 rpm with forward and reverse rotation capability, providing operational flexibility for different winding tensions and material handling requirements.

Trade-offs

• Manual operation limits throughput: As a manually operated machine, production throughput is inherently dependent on operator skill and speed, making it unsuitable for high-volume manufacturing but appropriate for R&D or small-batch production.
• Restricted to small cylindrical cells: The machine is limited to cylindrical cells within Φ30 mm, which constrains its applicability to larger-format cells or non-cylindrical form factors without additional customization.
