[Abstract]:The research and development, manufacture and application of industrial robots are the important symbols to measure the level of scientific and technological innovation and high-end manufacturing in a country, and the key to the realization of Chinese manufacturing 2025. Industrial robot has a wide range of applications, high control accuracy, low labor costs and many other advantages. But there are still some problems to be solved in the Chinese market. Due to the technology monopoly of developed countries such as Europe and Japan, the cost of industrial robots is high, and the underlying procedures can not be developed and transplanted to meet the flexible production requirements and cost control requirements of enterprises. The path planning algorithm is one of the core technologies of industrial robot software monopoly in developed countries such as Europe and Japan. The non-development of the path planning algorithm limits the flexibility of the production process and increases the cost of introducing robots into small and medium-sized processing enterprises. Aiming at the above problems, combining the forward and reverse kinematics principle of industrial manipulator and the two basic path planning algorithms of straight line and arc, the corresponding MFC program based on dialog box is developed on VS2010 platform with C language. The algorithm is developed and simulated in detail in various environments. The algorithm has the advantages of high portability and high precision. Then, we developed an open SCARA four-axis manipulator with an industrial PC motion control card. Combined with the principle of geometric kinematics analysis, the bottom development of PTP path planning algorithm is realized on the GTS-400-PV-G motion controller of Gugao Company, and it is successfully applied to the work platform based on vision guidance. Good real-time and reliable accuracy and stability. In this paper, the development and research trends of industrial robot are introduced, and the theoretical knowledge of robot kinematics and path planning algorithm is described in detail. Combined with theoretical knowledge, the software implementation and simulation of two path planning algorithms, straight line and arc, on VS2010 platform are studied. Then, a SCARA four-axis manipulator is designed and developed, and the detailed hardware system design and software code are given. Finally, three applications of SCARA four-axis manipulator based on machine vision are explained. Through the analysis of experiment and simulation results, it is shown that the self-developed industrial robot can meet the requirements of visual guidance accuracy, work stability, flexible program development, and greatly reduce the cost. Promote the promotion and use of industrial robots in small and medium-sized processing enterprises.
