Metal shaft detection based on machine vision technology

The automotive manufacturing industry has always been the main field of machine vision applications. With the continuous improvement of the industry's automation level, the scope of application of machine vision has been unprecedentedly expanded. In addition to traditional welding applications, machine vision is used to load and unload machine tools, and to stack materials. , Sanding, painting, testing, assembly and other fields have also been widely used.

As a common component in the automobile manufacturing industry, metal shafts play a very important role in the entire automobile manufacturing industry. Therefore, in the production and assembly process, it is necessary to ensure that all types of metal shafts are qualified to ensure that the main components of the automobile, such as engines, etc. The parts can work normally.

Aiming at the quality of metal shafts, traditional testing methods are difficult to meet the testing needs of automated production lines. Therefore, machine vision-based metal shaft testing has been quickly recognized by the industry because of its high speed and high efficiency.

Metal shaft detection effect chart Today, Vevision image will take the detection of the angle of the hole at the end of the metal shaft as the starting point to bring you a preliminary vision of metal shaft detection based on machine vision. The camera used in this test is MV-EM510M Gigabit Small An industrial camera with a resolution of 5 megapixels. It is an industrial camera equipped with a CCD in the MV-EM series of cameras.

Detection object: detect the angle value between the 6 holes on the end face of the metal shaft to determine whether it meets the requirements.

Detection method: The metal shaft is fixed by a fixed mechanism, and the industrial camera is taken on the conveyor belt to take a picture. The software automatically obtains the relevant angle value and compares it with the standard value to determine whether it is consistent. The 5 megapixel industrial camera selected for this camera has a frame rate of 15 frames / s higher than similar cameras, so while ensuring resolution, the number of metal shafts that can be detected can reach 6-10.
