Research and Design of the Vision Positioning System of High-Precision Surface Mounting Machine

According to the requirements of functions for high precision surface mounting machine, this paper designs the working flow of vision system in the one-ann surface mounting machine, presents the research on system structures, hardware arrangement, and imaging optical path, and designs an imaging system for the one-ann surface mounting machine. Finally, an experimental vision system is established based on the discussions in the paper and an experiment has been conducted to simulate the working conditions of surface mounting machine. The result shows that the vision imaging system can satisfy the requirements of system controllability and imaging precision.
