Assembly Line Inspection Of Brake Master Cylinder Piston Based On Machine Vision

In the process of mass industrial production，whether Artificial visual measuredthe brake master cylinder piston assembly is qualified or not，it is lower efficiency andlower pass rate，however，Machine vision inspection method can greatly improveproduction efficiency and the degree of automation，moreover Machine Vision is easyto implement information integration. Considering the problems above, This topic hasdeveloped a device with Assembly line inspection of brake master cylinder pistonBased on machine vision.Detection device is mainly composed of three parts: mechanical parts,controland visual part. The machine vision is the core of this device, It is able to achieveimage of target parts and image processing.the results is transmitted to the PLC by machine vision for system control, whichimplements the system integration, thus greatly reduces the human factors, raised thequalification rate of products and production efficiency.First, this paper introduces the research background and research significance ofthis topic, as well as the application and development status of machine vision.Secondly, this paper introduces the overall design of the apparatus, including thedesign of transmission mechanism，working principle of brake master cylinder, aswell as the method of PLC control of stepping motor and the specific wiring diagram.In the aspect of hardware design，This article embarks from the selection principle，Detailed introduces the product selection and specific parameters of machine visionpart and control part.Then, introduced the writing principle of machine vision applications and controlprocedures through the program flow chart，and introduces the concrete algorithm interms of relevant program design. In Chapter five, introduced Calibration of thesoftware.as well as image enhancement and image segmentation algorithm, inaddition, elaborate effects with way the lighting for machine vision detection.Finally, we test large quantities of products by this device， verify that the deviceare reliable and stable.And based on the research of this paper, this paper puts forwardthe further idea.
