Modeling and Simulation of Mounting Machine Based on VRML

Abstract

Mounting machine is the most critical bottleneck equipment in the SMT, the production efficiency of which restricts the entire assembly line's productivity dramatically. In order to enhance the virtual manufacture of paste simulation for PCB circuit modular, it is essential and critical for virtual reality simulation to build 3D model for the mounting machine in an efficient and accurate way. Based on the modeling principles, we have done extensive research on critical techniques on VRML geometric modeling. We have proposed the VRML based method that utilizes several modeling tools to build the geometric models efficiently. Using the boom mounting machine as an example, we have focused on the interior and the exterior cases of the mounting machine, to illustrate the construction of its static model that is based on VRML. The result of the simulation has proved the efficiency of the modeling methodology. The models generated have high degree of fidelity. This paper has built the foundation for visual system of mounting machine.
