In high-end manufacturing, coating quality is a critical determinant of product reliability and service life. Whether for PCB conformal coating, semiconductor encapsulation materials, automotive electronic coatings, or medical/biotechnical coatings, even minor coating defects can pose potential risks of product failure.

Guangdong Anda Automation Solutions Co., Ltd. has introduced the Dual-Sided On-the-Fly Imaging Coating AOI system, which integrates AI vision and on-the-fly imaging technology to deliver an efficient and accurate solution for coating inspection.

Adopting on-the-fly imaging technology to complete image acquisition during motion, the single-field inspection time is 0.23 seconds, and the minimum detectable diameter is 0.1mm, improving inspection throughput while ensuring precision.

This measurement method is based on the principle of chromatic confocal sensing. A white-light point source  emits a broad-spectrum beam. A lens group then creates  axial chromatic aberration, meaning different wavelengths  focus at different points along the optical axis. When the  light irradiates the film surface, only the specific wavelength  that satisfies the confocal condition is reflected back and  passes through the pinhole. A spectrometer analyzes this  wavelength to precisely determine the corresponding film  thickness or surface height.

The system supports full-process automation from product scanning and image capture to result output, enabling rapid changeover to meet the needs of multi-variant production.

The system can be flexibly configured to support two typical production line layouts:

Including Auto-Elevating Conveyor, Buffering Conveyor, iCoat-3 Coating Machine, ACI-F1200/500 Single-Sided On-the-Fly Imaging Coating AOI, Curing Oven and other equipment, realizing full-process automation of coating, inspection and curing.

Supports manual board loading/unloading. The production line configuration includes two coating machines (iCoat-3 and iCoat-5), two curing ovens, Dual-Sided On-the-Fly Imaging Coating AOI, and multiple buffering and elevating equipment, suitable for high-efficiency and complex processes of dual-sided coating.

Both solutions have quick changeover capabilities to adapt to multi-variety and small-batch production needs, and can conduct data interaction with MES systems to achieve quality traceability and process control.

Anda is committed to promoting the intelligent development of the manufacturing industry through technological innovation. Integrating machine vision, motion control and AI algorithms, the system provides reliable quality assurance for precision coating processes.
