1. Device function description
This equipment is mainly used for online inspection of PCB three-proof paint spraying area. The general defects are missing spraying, multi-spraying, splashing paint on protective parts, etc. It can be placed in front of the furnace (wet film station) and after the furnace (dry film worker). bit), the front and back can be tested at the same time. It mainly uses conformal paint to produce different color characteristics under the irradiation of purple light for visual analysis. Detected items include
uDetect multi-spray, splash paint and missing spray, see the figure below
uSet the QR code, see the figure below .
The operation method is: put it in the customer's assembly line, the tested product flows into the testing equipment, moves to the designated photoelectric position, takes pictures of the upper and lower CCD camera signals, and has a professional image software analysis platform - GOI platform for intelligent analysis of the image, Instead of manual visual inspection. And separate GOOD and NG pieces, discharge.
The entire testing process is automated, fast, intelligent, and standardized. The entire testing process achieves uniform quality and standardized rapid testing.
Since the entire testing process is automated, one person can control multiple devices, which can save a lot of manpower while improving efficiency.
