In today’s industrial manufacturing, due to the limitations of science and technology, manual inspection methods are still used to detect product surface defects. Due to manual limitations and backward technology, this method is not only slow and inefficient in detecting products, but also in the detection process. Errors are easy in the process, which leads to unqualified test results. With the development of computer technology; surface defect detection technology based on machine vision technology has emerged. The emergence of this technology has greatly improved the efficiency of production operations, and avoided manual factors affecting the accuracy of inspection results due to operating conditions and subjective judgments. Machine vision can better detect surface defects and quickly identify product surface defects. defect. For example, screws and nuts have strict quality requirements, and the amount of screws and nuts used is generally large, and they are produced in large quantities. At this time, it is very difficult to rely on manual inspection for appearance inspection, so optical image inspection equipment is used for appearance. Testing should be more appropriate.

Machine vision inspection is to use machines instead of human eyes for measurement and judgment. The machine vision system refers to the conversion of the captured target into an image signal through a machine vision product (ie, image capture device, divided into CMOS and CCD), which is transmitted to a dedicated image processing system, and transformed according to pixel distribution and information such as brightness and color. Digital signals; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the actions of the equipment on the spot according to the results of the discrimination.

Screw appearance size inspection equipment detects surface defects and flaws, and performs statistics, classification and analysis of defect information, optimizes production process control, classifies products, and classifies qualified and unqualified products to improve customer trust and satisfaction . In today's fiercely competitive manufacturing market, with the acceleration of production speed and increasing user requirements, ensuring continuous and stable product quality is crucial to the manufacturing industry.
