How This Coating Machine Works
Step 1: Substrate Loading
The substrate (aluminum foil for cathodes or copper foil for anodes) is loaded onto the unwinding structure. The auto rectify deviation system ensures perfect alignment before coating begins.
Step 2: Tension Control
The coated floating roller tension structure maintains constant tension as the substrate moves through the machine, preventing stretching or wrinkling.
Step 3: Coating Application
The coating structure applies slurry using the selected method:
- Slot die extrusion for precision intermittent or patterned coating
- Doctor blade for continuous coating
The PLC‑controlled feeding system ensures consistent slurry delivery, while FOS sensors monitor position for accurate coating start/stop.
Step 4: Drying
The coated electrode passes through the drying system with hot air circulation. Temperature is precisely controlled via thermocouples and heaters, ensuring complete solvent removal.
Step 5: Take‑up and Rewinding
After drying, the take‑up structure with float roller tension and tension sensor maintains consistent tension. The wrap‑up system with auto rectify deviation ensures the finished electrode is rewound perfectly aligned.
Step 6: Quality Monitoring
Throughout the process, the PLC touch screen displays real‑time parameters, and operators can adjust settings as needed. The high‑precision mechanical components guarantee coating accuracy and repeatability.
