This project is called "precision SMT processing equipment based on machine vision", which aims to develop a set of high-precision and high-efficiency surface mount technology (SMT) equipment based on machine vision technology. With the rapid development of electronic information industry, electronic products are becoming more and more miniaturized and integrated. The traditional perforated plug-in components have been unable to meet the needs of modern electronic products, and surface mount technology (SMT) has become the mainstream. SMT technology is widely used in smart phones, tablet computers, security electronic components and other fields, with high precision and high speed. However, at present, China still relies on imports in the core technology of SMT equipment, which seriously restricts the development of the electronic industry. Therefore, the research and development of precision SMT processing equipment with independent intellectual property rights has important practical significance. The research content of this project mainly includes the visual inspection system of high-speed and high-precision placement machine, the image processing technology of Mark point positioning and component recognition in the placement production, and the multi-objective optimization of the placement process. By integrating electronic control technology, servo control technology, pneumatic control and visual inspection technology, the project team is committed to achieving fast and accurate surface mount production. The project adopts machine vision technology and image processing algorithms to ensure high precision and high efficiency in the mounting process. At the same time, the project team used SolidWorks modeling and simulation to optimize the equipment structure and improve the installation speed and accuracy.
