Abstract

The gantry is a device that moves fine chips from the feeder to the PCB. While the gantry is moving the part, the camera checks the condition of the part. The purpose of this paper is to find the path with the shortest travel time of the gantry and calculate the travel time according to the path. stop_motion is a way to check the status of the parts currently in use. This paper presents the moving_motion method and the fly_motion method with maximum speed in front of the camera. In addition the signature method was used to inspect the condition of the parts. When comparing the moving time of the three types of gantry, the moving_motion method improved by 9.42% and the fly_motion method by 17.73% compared to stop_motion. When the fly_motion method proposed in this paper is used for the gantry movement path, it is expected that productivity will be improved.

갠트리는 미소 칩을 피더에서 기판까지 이동하는 장비이다. 갠트리가 부품을 이동하는 중에 카메라는 부품의 상태를 검사한다. 본 논문의 목적은 갠트리의 이동시간이 가장 짧은 경로를 찾고 그 경로에 따른 이동시간을 계산한다. 현재 사용되고 있는 부품의 상태를 검사하는 방법은 stop_motion 방식이다. 본 논문은 moving_motion 방식과 카메라 앞에서 최대속도를 갖는 fly_motion 방식을 제시한다. 또한, 부품 상태의 검사는 시그니처 방법을 사용하였다. 3가지 방식의 갠트리가 이동하는 시간을 비교했을 때, stop_motion보다 moving_motion 방식은 9.42%, fly_motion 방식은 17.73% 향상되었다. 본 논문에서 제시한 fly_motion 방식을 갠트리 이동 경로에 사용할 경우 생산성이 향상될 것으로 생각한다.
