Description

Technical Field

[0002] Machine vision has wide applications, and the rapid development of manufacturing and the upgrading of industrial automation have brought new opportunities and challenges to machine vision. Users and manufacturers have increasingly higher requirements for product quality, demanding not only good performance but also a good appearance, i.e., good surface quality. However, surface defects are often unavoidable during product manufacturing. Surface defects are areas of uneven physical or chemical properties on the product surface, such as scratches, spots, and holes on metal surfaces, color differences and indentations on paper surfaces, and inclusions, breakage, and stains on non-metallic surfaces such as glass. Surface defects not only affect the aesthetics and comfort of products but also adversely impact their performance.

[0003] A rotating camera device for inspecting product surfaces is provided, enabling automated machine vision inspection. It boasts significant advantages such as safety, reliability, a wide spectral response range, long-term operation in harsh environments, and high production efficiency. The machine vision inspection system acquires surface images of products using appropriate light sources and a vision camera. It then extracts feature information from the images using corresponding image processing algorithms. Based on this feature information, it performs operations such as locating, identifying, and classifying surface defects, as well as statistical analysis, storage, and retrieval.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0007] A dovetail block, which is slidably connected to the inside of a dovetail groove, and a camera is provided at the upper end of the dovetail block;

[0008] A fixing mechanism is provided on the inner side of the annular guide rail;

[0009] The product to be tested is located inside the annular guide rail and is fixed by a fixing mechanism.

[0010] Furthermore, an assembly is provided at one end of the outer frame.

[0011] Furthermore, a light source is provided on one side of the upper end of the annular guide rail, and three sets of dovetail blocks are slidably connected inside the dovetail groove of each layer of the annular guide rail.

[0012] Furthermore, the annular guide rail is equipped with a clamp, which is used to fix the fixing mechanism.
