Abstract

Gentry is responsible for moving the fine chip in the device that mounts the chip on the PCB. However, it is not easy to increase productivity because of the mechanical limitations of the gantry. Therefore, in this paper, we try to solve the method to increase the productivity by software. For this purpose, we propose a method to improve the productivity by shortening the movement time of the gantry. First, we calculated the total travel time for the current method(stop-motion). In addition, the total travel time is also calculated for the travel time reduction method presented in this paper. This method reduces the travel time by checking parts without stopping in front of the camera. As a result, we showed that the proposed method shortened the time of 16%. In the future, we will study time calculation methods for other types.

미소칩을 PCB상에 실장하는 장비에서 그 칩을 이동해주는 역할은 겐트리가 하고 있다. 그런데 겐트리의 기계적 한계 때문에 생산성을 증가시키는 것은 쉽지 않다. 따라서 본 논문에서는 생산성을 높일 수 있는 방법을 소프트웨어적으로 해결하고자 한다. 이를 위해 겐트리의 이동 시간을 단축함으로써 생산성을 향상시킬 수 있는 방법을 제시한다. 먼저, 현재 사용하고 있는 방법(stop-motion)에 대해 총 이동 시간을 계산해 보았다. 그리고 본 논문에서 제시하는 이동 시간 단축 방법(moving-motion)에 대해서도 총 이동 시간을 계산해 보았다. 이 방법은 카메라 앞에서 멈추지 않고 부품 검사를 함으로써 이동 시간을 줄이는 것이다. 그 결과 본 논문에서 제시한 방법이 16%의 시간을 단축하였음을 보여주었다. 향후에는 다른 타입에 대해서도 시간 계산 방법을 연구하는 것이다.
