Abstract
A SMT machine is used to place electronic components on a PCB precisely. To place it precisely, after a component inspection, it finds an offset value using a vision camera, and places the precise position on the PCB. In general, to inspect the components with a vision camera, the components stop in front of the camera for inspection, then move to the placement position. On the other hand, if they do not stop in front of a camera, the inspection time will be shortened and the productivity would be increased. In this thesis, when inspecting without stopping in front of a camera, the fastest way among various routes is described. For the gantry passing over a vision camera, both the distance and speed of a gantry moving trajectory were studied, and there was approximately 5% speed increment when using the method suggested in this thesis.
