Description

Technical Field

[0001] The utility model relates to the field of visual inspection of equipment parts, in particular to a visual inspection control device for equipment parts. Background Art

[0002] In the assembly of automotive heat exchange systems, time is a severe challenge. Due to the extremely limited assembly time, it is difficult for us to accurately judge the slight differences in the installation of parts in a short time. This leads to frequent product scrapping in production, resulting in a large waste of manpower and material resources. In order to solve this problem, the relevant technology adopts a detection method combining sensors and cylinders to ensure accurate identification of the difference between parts through their synergy. Sensors play an important role in detecting protruding parts or detection points where the difference between the two is large, while cylinders play a key role in accurately locating the grooves of parts. Although this method can determine whether the parts are installed correctly to a certain extent, there are still some shortcomings. Points: First, the existing detection methods only focus on a few detection points, which is difficult to fully reflect the installation status of the parts and may lead to misjudgment; secondly, when accurately positioning the grooves of the parts, the accuracy of the cylinder has an important influence on the detection results, but the accuracy of the cylinder may be affected by many factors, resulting in failure of precise positioning; in addition, the existing detection methods mainly focus on the protruding and grooved parts of the parts, and it is difficult to detect other important features, such as threads, scales, etc.; finally, due to the reliance on the synergy of sensors and cylinders, the existing detection methods have a relatively slow detection speed, which may lead to reduced production efficiency. In order to solve these problems, the utility model proposes a visual inspection control device for equipment parts. Utility Model Content
