초록

SMT장비는 전자 부품을 흡착하여 PCB상에 정확히 실장 하는 장비이다. 이를 위해서는 중간 위치에 설치된 카메라 앞에서 정지하여 비전 검사를 한 후 실장 위치로 이동한다. 그 이동 경로의 타입은 16가지가 되며, 그 중에서 (sLa-Camera-pLb)경로에 대해 가장 빠른 시간에 실장 할 수 있는 알고리즘을 본 논문에서는 제시한다. 이를 위해서는 카메라 위치에서 정지하지 않고 이동하면서 비전 검사할 때 수많은 궤적 중 어떤 궤적이 가장 빠른 시간에 검사 후 실장 할 수 있는 경로인지를 찾는 알고리즘을 제시한다. 그 결과 카메라 앞에서 정지하여 검사 후 이동하는 방식보다 16%의 시간 단축 효과가 있음을 시뮬레이션을 통해 입증하였다.

SMT is an equipment that picks up electronic components and does precise placing onto PCBs. In order to do this, it stops in front of a camera installed in the middle to go over vision inspection. And after that it is move for placing. There are 16 different types of routes in this process. This paper presents the fastest algorithm to place (sLa-Camera-pLb) among all these routes. In order to do this, instead of stopping in front of camera the object should move on while going over the vision inspection. Among all possible tracks, this thesis will provide algorithm to find out the fastest tracks to do vision inspection and placing. And as a result, this thesis have demonstrated that this method can save about 16% of time compared to going over inspection while the object is standing still through simulation.
