The feeding robot 38 sucks the screen from above the second screen transfer tray 29, and places the screen in a tray in the good tray feeding mechanism 36 or the bad tray feeding mechanism 37 according to the detection result. After the screen is full of the trays, the trays are discharged by the good tray discharging mechanism 36 or the defective tray discharging mechanism 37. The method comprises the following steps of processing images collected by a camera: and extracting the partial image to be measured by threshold segmentation. The graph after the division is a figure. And preliminarily judging whether the acquired image is correct or not according to the area of the image obtained by the segmentation, popping up a warning message if the acquired image is correct, and carrying out the next step if the acquired image is correct. And performing expansion and corrosion operations on the extracted partial image to be detected, filling up pores in the image, and filtering noise interference. And extracting the outer edge profile of the image to be detected. And converting the partial image to be detected into a convex polygon. And calculating the difference value between the convex polygon and the partial image to be detected. And carrying out corrosion operation on the difference value to remove a small noise part. And calculating connectivity, and dividing the connectivity into different areas according to the connectivity. And calculating the area of each part, and judging whether defects exist according to a preset threshold value. If the defect exists, the defect is marked as a defective product, the actual length and width of the defect are marked at the defect position, and the position and the type of the defect are recorded. If no defect exists, the product is marked as good. After the overall image detection is completed, in order to ensure the detection accuracy, the parts with multiple defects (four side lines and four corners of the piece to be detected) need to be subjected to key detection. The detection step is illustrated in the lower left corner. Firstly, selecting a lower left corner region of an image to be sequenced according to the length and width of a graph to be tested, and calculating the area, the length and the width and the like of the region; then, carrying out inscribed circle calculation on the image to be measured at the lower left corner to obtain the radius of the inscribed circle; and selecting area and radius thresholds according to actual product requirements, and judging whether the lower left corner is flawless. And similarly, processing the other key detection areas of the workpiece and judging whether the workpiece has defects.
