Abstract

Car circuit in the base of the injector is one of the important parts, such parts are mainly used for precision cylindrical parts with the welding assembly precision measurement of the diameter size of the parts needed to keep the assembly precision. In China, has been relying on manual sampling methods on the base of the injector testing, traditional detection methods have been unable to meet the needs of production flexibility and the degree of automation of the. In this paper, the characteristics of the inner diameter of the base of the injector detection method of visual detection technology the injector base diameter measurement and design of automatic test equipment can automatically detect the inside diameter of the base of the injector. The main content of the chapters in this article are as follows: the first chapter on the background and significance of the technology of machine vision inspection, and then introduced the development and application of machine vision technology status and visual detection technology applications in various industries in the basis of the status quo, an overview of The purpose of this study and the main work. The second chapter in the introductory injector base automatic test equipment basic structure and working principle based on the system's hardware systems (mechanical and motion control systems and visual systems) carried out a detailed analysis and design. Chapter designed the injector base automatic control system; details PLC definition, hardware structure, software and works, while the hardware configuration, the PLC program by Mitsubishi FX series programming software GX-Developer Design. In addition, detailed IO card selection and programming methods. Chapter modular design concept, and object-oriented technology, software development in VC 6.0 environment, automatic test equipment on the inside diameter of the base of the injector, the initialization module, image acquisition module, image processing modules, motion control module, output the print module module. The fifth chapter in the anti-jamming measures introduced in this article detection equipment, the equipment the injector base line measurement in the industrial field, and according to the measurement results of the measurement system accuracy. The measurement results show that the device detection accuracy of ± 8μm, detection speed of up to 2 seconds 3. Chapter summary of the full text of the work, and to propose ideas for further research on the basis of the study of the text.
