The device requires a stable single-phase 220VAC±10% (or 110VAC) power supply at 50/60Hz and continuous operation mode. Installation must account for the split-unit dimensions and combined weight of approximately 290kg.
- Power Supply Constraint: The device requires a single-phase 220VAC±10% (or 110VAC) power supply at 50/60Hz, with no other voltage or frequency configurations specified.
- Installation Space Constraint: The split-unit design requires separate floor space for the unwinding unit (W450mm*D900mm*H500mm, approx. 120kg) and the winding unit (W500mm*D900mm*H500mm, approx. 170kg).
- Operational Speed Constraint: The mechanical operation speed is limited to a maximum of 6m/min, and the tension control is capped at 50N.
This procedure covers the initial setup and operation of the Atomfair-WUD6820 for winding and unwinding coil materials. It includes steps for installation, material loading, parameter setting, and operation.
Required Equipment: Atomfair-WUD6820 device, Coil material (e.g., electrode, film), Manual tension adjustment mechanism
- Position the device
Position the unwinding and winding units on a stable, level surface, ensuring adequate clearance for the specified installation dimensions and material path. - Connect power supply
Connect the device to a single-phase 220VAC±10% (or 110VAC) power source with the correct frequency (50/60Hz) and ensure proper grounding. - Load the coil material
Load the coil material onto the unwinding shaft, threading it through the guide rollers and onto the winding core, ensuring proper alignment and tension. - Set tension and speed parameters
Set the desired tension (up to 50N) and winding speed (up to 6m/min) using the automatic tension control system and manual adjustment support. - Start the winding process
Start the device and monitor the winding process, ensuring the correction function maintains winding neatness and the tension remains stable. - Monitor and adjust during operation
Monitor the winding and unwinding operation, making manual tension adjustments as needed and verifying the material tracks correctly on the guide rollers. - Stop and unload the finished roll
Stop the device once the winding is complete, then carefully remove the finished roll from the winding shaft and prepare for the next cycle.
What is the maximum tension and winding precision of the Atomfair-WUD6820 for lithium-ion battery electrode rewinding?
The Atomfair-WUD6820 provides a maximum tension control of 50N and a winding precision of ±0.5mm, ensuring consistent tension and neat winding for lithium-ion battery electrode plates. This precision is critical for maintaining electrode integrity during the rolling process.
Can the Atomfair-WUD6820 be integrated with existing roller presses or other coil processing lines?
Yes, the device features an independent electrical control system and can operate in linkage with other equipment via a relay interface. Its split-structure design for unwinding and winding units allows flexible integration with roller presses for lithium-ion battery electrode processing or other coil material lines.
What are the installation space and power supply requirements for the Atomfair-WUD6820?
The unwinding unit measures W450mm x D900mm x H500mm and weighs approximately 120kg, while the winding unit measures W500mm x D900mm x H500mm and weighs approximately 170kg. It requires a single-phase 220VAC±10% power supply (110VAC customizable) at 50/60Hz, with a maximum mechanical operation speed of 6m/min.
The Atomfair-WUD6820 automatic winding and unwinding device is engineered for precision coil material handling in lithium-ion battery electrode processing and optical/functional film slitting, featuring active winding with automatic tension control up to 50N and ±0.5mm winding precision. Its split-unit design and relay interface enable flexible integration with roller presses or standalone operation, though the 250mm maximum coil diameter and 300mm guide roller width impose clear material size constraints.
Positive
- Active tension control with correction: Active winding design with automatic tension control up to 50N and end-correction function ensures consistent tension and excellent winding neatness, critical for uniform electrode rolling and film slitting quality.
- Split-unit design with relay interface: Unwinding and winding units are structurally separate, and the built-in independent electrical control system can link with other equipment via relay interface, enabling flexible integration into roller press lines or standalone operation.
Trade-offs
- Limited coil diameter and width: Maximum winding/unwinding diameter is 250mm and guide roller width is 300mm, restricting the device to smaller coil formats and requiring upstream/downstream equipment to match these dimensions.
- Manual tension adjustment on unwinding: The passive unwinding mode requires manual tension adjustment, which may reduce process repeatability and demand operator expertise to maintain consistent tension during high-precision applications.
