Description

Watch flaw machine vision detection grading device Technical Field The utility model relates to the technical field of watch flaw visual detection, in particular to a watch flaw machine visual detection grading device. Background A visual inspection device is an apparatus that utilizes machine vision technology to inspect a product or component. It typically includes hardware parts (e.g., industrial cameras, light sources, lenses, etc.) and software parts (image processing algorithms). The vision inspection device can simulate human vision to identify, analyze and detect defects or anomalies in the product, thereby improving production efficiency and product quality. The visual detection device has wide application in manufacturing industry, including size and shape detection, surface quality detection, position and gesture detection, automatic sorting and identification, product defect detection and the like, and the machine visual detection is not influenced by human factors, so that tiny flaws can be accurately identified, and the detection accuracy and consistency are greatly improved. With the maturity of machine vision detection technology, many research institutions and enterprises in China already apply the machine vision technology to the detection classification of watches, and the working principle is that the watches move at a uniform speed below a vision detection device, one or more line scanning cameras in the vision detection device are used for scanning and capturing images of the watches so as to identify flaws which do not accord with preset standards, such as scratches, pits, uneven colors and the like, and then the images are led into an identification model to detect flaws and classify the detected flaws. When the device is specifically used, the watch is directly placed on the conveying belt and then moves at a uniform speed below the visual detection device, and due to the lack of the limiting structure, the watch is easy to misplace or skew along with the movement of the conveying belt, so that the difficulty in scanning detection is increased, and the detection grading efficiency is affected.
