The Online PCBA Coating Robot is built for continuous, high-precision conformal coating in SMT production lines. Multi-axis arms with adjustable spray valves deliver uniform adhesive and protective layers across single- or double-sided PCBs. Integrated online conveyors provide smooth transport with precise positioning. IR/UV curing zones with independent cooling ensure consistent curing without thermal stress. CCD vision monitors coating quality in real time. PLC-based control allows operators to adjust speed, spray height, and coating volume, enabling high throughput and uniform quality across PCBA assemblies and LED modules.
The online robot uses multiple axes to apply coatings accurately on complex PCB surfaces. Adjustable spray valves accommodate various material viscosities, including UV adhesives and conformal coatings. Edge recognition and height detection ensure uniform application, while preventing under- or over-coating. Supports single- and double-sided boards. This guarantees repeatable coverage for dense SMT PCBs, LED assemblies, and high-value electronics in continuous production.
The system features robust aluminum and stainless steel conveyors driven by stepper motors, ensuring precise, stable PCB transport. Width and height are adjustable for different board dimensions. Push and buffer mechanisms prevent misalignment and maintain position during coating. Fiber optic sensors detect board presence and prevent collisions. Optional return and spacing adjustment allows flexible line configuration. The design supports high-throughput online coating while maintaining uniform coverage and board integrity.
Integrated IR/UV curing zones provide consistent energy to rapidly cure coatings, while independent cooling protects components. PLC-based control allows real-time adjustment of conveyor speed, curing intensity, and zone configuration. CCD vision monitors coating uniformity and detects defects before PCBs exit the line. Full automation reduces manual intervention, ensures repeatable quality, and maintains reliable conformal coating on PCBs and LED modules for large-scale SMT production.
