Abstract

Gentry, an SMT equipment, is a device that absorbs electronic components from the feeder and mounts them correctly on the PCB. At this time, the gantry stops in front of the camera to check whether the parts are correctly adsorbed. In this paper, we propose a method to shorten the moving time by moving the gantry without stopping in front of the camera. This method shows that the moving time is shorter than that of the conventional method by finding a path that can be moved in the fastest time among the various moving paths. The proposed method (moving-motion) reduces the gantry travel time by 20% compared to the conventional method (stop-motion).

SMT장비 인 겐트리는 전자 부품을 피더에서 흡착하여 기판위에 정확히 실장하는 장비이다. 이 때 부품이 정확히 흡착되었는지를 검사하기 위해 카메라 앞에서 겐트리는 잠시 멈춘다. 본 논문에서는 이동 시간을 단축하기 위해 카메라 앞에서 겐트리가 정지하지 않고 움직이면서 검사를 할 수 있는 방법을 제시한다. 이 방법은 여러 이동 경로 중 가장 빠른 시간에 이동할 수 있는 경로를 찾아 기존 방법보다 이동 시간이 단축됨을 보여준다. 제시된 방법(moving-motion)은 기존 방법(stop-motion)보다 겐트리의 이동 시간을 20%나 단축시킨다.
