Inline Coating AOI Inspection System High Precision Detect Over Coating Less Coating Thickness

The HP-AOI45B is a fully integrated inline automatic optical inspection system designed for seamless operation within automated SMT production lines. Featuring a standard SMEMA communication interface, it automatically handshakes with upstream coating equipment and downstream curing furnaces or unloaders—enabling true lights-out quality verification with minimal operator intervention.

The intelligent electric width adjustment (50-450mm) responds to program commands, eliminating manual changeovers between different PCB sizes, while the conveyor speed (0.5-3.5m/min) synchronizes precisely with line flow. With total power consumption of only 2KW (AC220V 50Hz) and robust construction weighing approximately 600KG, the HP-AOI45B integrates cleanly into facility infrastructure.

Features a 5-megapixel global color camera paired with a telecentric lens that captures distortion-free images with exceptional clarity. Telecentric technology ensures consistent magnification regardless of object distance, critical for accurate measurement of coating edges and defects. The dual-color annular light source combines UV light (for fluorescent tracer excitation) and white light, providing optimal illumination for detecting overcoat, undercoat, foreign matter, splashing, and edge clarity issues.

X, Y, and Z axes are driven by servo motors with fully closed precision screw modules, delivering ±0.02mm repeatability for precise camera positioning over inspection points. This ensures even the smallest defects are consistently captured and analyzed.

Professional AOI control software running on industrial control computer with comprehensive capabilities:

• Flexible detection area definition supporting round, rectangular, and polygonal shapes
• Advanced area management with copy, mirror, array, and rotation operations
• Intelligent algorithm comparing images against pre-set reference points
• SPC data statistics and traceability with barcode integration
• Storage for over 1,000 running programs

Ideal for post-coating inspection in various industries:
