Test material: mobile phone appearance defect detection.
Customer detection requirements description: mobile phone screen; Metal phone frame.
Innovation:
Fan Sheng's original optical scheme, take the bad picture, by calculating the contrast, get the location of the defect, calculate the length, width, area, variation, circular degree and other attributes of the defect, analyze whether the defect exceeds the standard;
With the camera instead of the human eye detection, the missed detection rate is 0.3%, the overdetection rate is 5%, and the beat of 6s/pcs greatly improves the output while reducing the missed detection rate, fully automatic loading and unloading, and the feeding method can be used according to customer needs, pallet unloading or film unloading, effectively reducing labor costs.
