In high-end manufacturing, the quality of coating processes directly impacts product reliability and service life. Whether it is protective coatings on PCBs, semiconductor encapsulation materials, automotive electronics coatings, or medical bio‑coatings, even the slightest coating defect can become a potential failure risk.
XinHua Intelligent Equipment Co., Ltd. has launched its Double‑Sided On‑the‑Fly Coating AOI system, which combines AI vision with fly‑scan technology to deliver an efficient and accurate solution for coating inspection.

Full Coverage of Six Inspection Items
The system supports six key inspection categories: over‑coating, under‑coating, splashing, bubbles, foreign particles, and thickness measurement. It enables end‑to‑end process control – from visual alignment to thickness evaluation.

Fly‑Scan Technology Boosts Efficiency
With on‑the‑fly imaging, the system captures images during motion without stopping. The inspection time per field of view is just 0.23 seconds, and the minimum detectable defect size is 0.1 mm. This ensures high precision while significantly improving throughput.

AI Algorithms Enhance Defect Recognition
-
The system leverages the SAM (Segment Anything Model) for coating area extraction.
-
Supports anomaly detection even under zero‑defect sample conditions.
-
When sufficient defect samples are available, ACC‑Unet is employed for high‑precision defect segmentation.
-
The entire workflow – from product barcode scanning and image acquisition to result output – is fully automated. Quick changeover capability accommodates mixed‑model production with ease.

Integrated In‑Line Solutions
The system can be flexibly configured to support two typical production line layouts:
-
Single Coater + Single Oven:
Includes an automatic loader/unloader, conveyor sections, an iCoat‑3 coater, an ACI‑F1200/500 single‑sided on‑the‑fly coating AOI, and a curing oven – enabling automated coating, inspection, and curing in one continuous line. -
Dual Coaters + Dual Ovens:
Supports manual board loading/unloading. The line consists of two coaters (iCoat‑3 and iCoat‑5), two curing ovens, a double‑sided on‑the‑fly coating AOI, plus multiple conveyors and lifting units. This configuration is ideal for high‑efficiency processing of complex, double‑sided coating applications.
Both solutions offer rapid changeover capabilities to handle multi‑product, small‑batch production, and can interface with MES systems for quality traceability and process control.
XinHua Intelligent Equipment Co., Ltd. is committed to driving the intelligent evolution of manufacturing through technological innovation. This system integrates machine vision, motion control, and AI algorithms into a robust platform, providing reliable quality assurance for precision coating processes.
