[Abstract]:Mounting machine is the symbol of modern electronic manufacturing equipment. It covers a wide range of disciplines, such as machinery, optics, electronics, automation and computer. It involves high-speed and high-precision control, precision machining, and so on. Precision vision inspection and computer integrated manufacturing are typical high-tech fields of mechanical and photoelectric integration. The system integration development of SMT machine is a complex project, which involves the organization of each module and the platform construction of system hardware and software. Firstly, the paper briefly introduces the current situation and future development trend of the SMT control system at home and abroad, gives the design basis of the SMT control system, and introduces the foundation of the SMT machine, including the working principle of the SMT machine. Workflow and mechanical structure. The structure characteristics of the core component of the mounting machine-the sticker head are analyzed. The hardware platform of SMT control system is designed, and the developed motion control system based on PC motion control card is established. The design idea and operation flow of task management software for mounting machine, including main interface, sub-menu, debugging interface and so on, are analyzed. In this paper, the mathematical modeling of the mounting process of the double-head multi-nozzle arch mounting machine is carried out, ignoring the influence of the secondary factors, the object to be studied is summarized as the solution of the TSP problem. By comparing the advantages and disadvantages of three intelligent optimization algorithms (simulated degradation algorithm, ant colony algorithm, genetic algorithm), the genetic algorithm which is the most suitable for this subject is selected for modeling and analysis, and the simulation is carried out by MATLAB software, and the results are obtained. Finally, combined with the hardware platform and control system software, the mount machine is simulated and tested, and the operation flow of each control module is analyzed, and the performance results satisfying the requirements are obtained.
