Description

Technical Field

[0001] The utility model relates to the technical field of workpiece detection, in particular to a high-reflective workpiece visual detection device. Background Art

[0002] Visual inspection refers to the process of converting the captured target into an image signal and transmitting it to the image processing system through an appearance visual inspection machine, and then converting it into a digital signal based on information such as pixel distribution, brightness, and color, so as to achieve visual judgment of the product. However, in actual application, for tubular materials with smooth surfaces and high reflectivity, such as copper tubes and stainless steel tubes, when performing visual positioning inspection, due to the high reflectivity of the workpiece itself, a mirror reflection effect will be produced at the edge of the cylinder, and the light cannot be reflected into the camera, making it difficult to achieve contour recognition. Secondly, because tubular materials are mostly set in a pipe system, and the pipe system is complexly arranged, there will be other tubular workpieces interlaced at the back, and the light source emitted from the front will be reflected by multiple overlapping workpieces, making it difficult for the camera to distinguish the workpiece to be inspected, and the light source cannot be placed behind the workpiece due to the presence of other workpieces, which makes visual inspection of tubular materials more difficult.
