This document outlines the operational constraints for the Atomfair-CEC-5729 continuous coater. These constraints are derived from the equipment's technical specifications and functional features.
- Compressed Air Supply Constraint: The coater requires a compressed air supply of 0.5 to 0.7 MPa for pneumatic components.
- Power Supply Constraint: The equipment operates on an AC220V/50Hz power supply with a maximum power consumption of 5 kW.
- Drying Temperature Constraint: The drying unit operates within an adjustable temperature range from room temperature up to 120°C.
- Coating Thickness Constraint: The achievable coating thickness is dependent on slurry characteristics and ranges from 40 to 200 μm.
- Environmental and Process Constraint: The equipment is designed for continuous operation and requires a stable substrate tension and alignment for optimal coating accuracy.
This guide provides the essential steps for operating the Atomfair-CEC-5729 continuous coater. The procedure covers setup, coating, and shutdown processes.
Required Equipment: Atomfair-CEC-5729 Continuous Coater, Compressed air supply (0.5-0.7 MPa), AC220V/50Hz power source
- Prepare the coater
Verify that the compressed air supply is connected and set to 0.5-0.7 MPa, and that the power cord is plugged into an AC220V/50Hz outlet. - Load the substrate
Thread the substrate through the unwinding unit, around the guide rollers, and onto the winding core, ensuring proper tension and alignment. - Set the drying temperature
Adjust the drying temperature controller to the desired value within the range of room temperature to 120°C, based on the coating solvent and substrate. - Set the coating parameters
Use the touch screen interface to set the desired coating speed, coating thickness, and tension control parameters according to the process requirements. - Start the coating process
Initiate the coating process by pressing the start button on the touch screen, and monitor the operation for any irregularities. - Monitor and adjust
Continuously monitor the coating quality and substrate alignment, and make fine adjustments to the coating thickness or tension as needed. - Shut down the coater
After completing the coating run, stop the machine, turn off the power, and disconnect the compressed air supply.
What is the maximum coating speed and how does it affect coating accuracy on the Atomfair-CEC-5729?
The maximum mechanical speed is 900 mm/min, but coating accuracy is specified as ±3 μm (with edge error ±5 μm) across the entire speed range. However, the actual coating thickness is determined by slurry characteristics and ranges from 40 to 200 μm, so higher speeds may require adjustments to drying temperature and tension to maintain accuracy.
What are the substrate width and tension requirements for the Atomfair-CEC-5729 coater?
The guide roller width is 330 mm, and the maximum coating width is 300 mm. The coater supports a maximum tension of 60 N (adjustable) and includes a substrate tension control system with deviation correction to ensure stable tape running. This makes it suitable for a variety of substrates used in lithium-ion battery R&D.
What are the utility and installation requirements for the Atomfair-CEC-5729?
The coater requires compressed air at 0.5–0.7 MPa and a power supply of AC220V/50Hz with a maximum power consumption of 5 kW. The overall dimensions are L1800×W1200×H1200 mm, and the equipment weighs approximately 1 ton. Ensure adequate space and utility connections are available before installation.
The Atomfair-CEC-5729 Continuous Experimental Coater is a three-roll transfer coating system engineered for R&D and pilot-scale secondary battery electrode production, delivering mass-production-level coating accuracy of ±3 μm (±5 μm edge error) with a maximum coating width of 300 mm and mechanical speeds up to 900 mm/min, supported by PLC-controlled tension and hot-air drying.
Positive
- High coating accuracy with comma scraper: The comma scraper metering structure combined with precision adjustment achieves ±3 μm coating accuracy (±5 μm at edges), suitable for consistent electrode fabrication in battery R&D.
- Integrated tension and drying control: Substrate tension control (up to 60 N) with deviation correction ensures stable web handling, while the hot-air oven with double-sided synchronous blowing provides uniform drying for quality electrode films.
Trade-offs
- Requires compressed air supply: Operation depends on an external compressed air source at 0.5–0.7 MPa, which may require additional laboratory infrastructure and increases installation complexity.
- Limited drying temperature range: The maximum drying temperature of 120°C restricts processing of solvent systems requiring higher evaporation temperatures, potentially limiting compatibility with certain slurry formulations.
