This equipment requires a compressed air supply of 0.5–0.7 MPa and a 220V/50Hz power source, with a maximum power draw of 5 kW. The drying unit operates at temperatures up to 120°C, and the coater must be installed on a stable, level surface capable of supporting its approximate 1.5-ton weight.
- Compressed Air Requirement: The coater requires a compressed air supply of 0.5–0.7 MPa for pneumatic components and tension control.
- Electrical Supply: The equipment operates on AC220V/50Hz with a maximum power consumption of 5 kW, requiring a dedicated electrical circuit.
- Drying Temperature Limit: The hot air drying unit is adjustable from room temperature up to 120°C, and exceeding this limit may damage the oven or substrate.
- Weight and Installation: The coater weighs approximately 1.5 tons and must be placed on a reinforced, vibration-free floor to maintain coating precision.
This procedure covers the standard startup, coating, and shutdown sequence for the Atomfair-IEC-5719 intermittent coater. Always verify all connections and settings before initiating the coating process.
Required Equipment: Touch screen control panel, Compressed air supply (0.5–0.7 MPa), Substrate roll, Coating slurry
- 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 a 220V/50Hz outlet. - Load the substrate
Mount the substrate roll onto the unwinding shaft and thread it through the guide rollers, ensuring proper tension and alignment. - Set coating parameters
Use the touch screen to select continuous or intermittent mode, and input the desired coating thickness, speed, and drying temperature. - Apply the coating
Start the coating process and monitor the slurry transfer, adjusting the micrometer or tension controls as needed to achieve uniform thickness. - Dry the coated substrate
Allow the coated substrate to pass through the hot air drying unit, ensuring the temperature is within the set range and the drying is uniform. - Wind the finished roll
Guide the dried coated substrate onto the winding roll, maintaining constant tension and checking for any defects. - Shut down the coater
After completing the run, stop the coating process, turn off the drying unit and power, and clean the rollers and coating head.
What is the maximum coating speed and precision of the Atomfair-IEC-5719 intermittent coater?
The Atomfair-IEC-5719 achieves a maximum mechanical speed of 900 mm/min with a coating precision of ±3 μm (edge error ±5 μm). This precision is enabled by the comma cutter metering and precision adjustment mechanism, ensuring high accuracy for R&D and small-scale production.
Can the Atomfair-IEC-5719 handle both continuous and intermittent coating modes, and what are the implications for electrode patterning?
Yes, the coater freely switches between continuous and intermittent modes, allowing selective coating for patterned electrodes. This flexibility is critical for lithium-ion battery R&D where precise electrode geometries are required, and it is supported by the three-roll transfer structure and PLC-controlled operation.
What are the substrate tension and drying capabilities of the Atomfair-IEC-5719, and how do they affect coating quality?
The coater provides adjustable tension up to 60 N with a winding precision of ±0.5 mm, ensuring stable tape running. Drying is performed by a hot air oven with upper and lower double-sided air blowing at temperatures from room temperature to 120°C, delivering uniform drying essential for thick coatings (40–200 μm).
The Atomfair-IEC-5719 three-roll transfer coater delivers ±3 μm coating precision with a 40–200 μm wet thickness range, making it well-suited for R&D and pilot-scale electrode fabrication in lithium-ion, supercapacitor, and nickel battery development. Its dual-sided hot-air drying and tension-controlled web handling support uniform coating at speeds up to 900 mm/min, though the 120°C drying ceiling and manual thickness adjustment define key operational boundaries.
Positive
- High coating precision: Comma cutter metering with precision adjustment achieves ±3 μm coating accuracy (edge error ±5 μm), enabling reproducible electrode films for battery R&D.
- Dual-sided hot-air drying: Upper and lower simultaneous air blowing in the oven provides uniform drying, reducing defects in thick or solvent-based coatings.
Trade-offs
- Limited drying temperature: Maximum drying temperature of 120°C restricts processing of high-boiling-point solvents or thermally sensitive binders, requiring lower web speeds or alternative drying strategies.
- Manual thickness adjustment: Coating thickness is set manually via micrometer (1 μm resolution), which increases setup time and operator dependency for reproducible batch-to-batch results.
