Abstract

본 발명은 전자부품 검사장치에 관한것으로, 플랫 패케이지 아이씨의 높이를 고려하지 않고 씨씨디 카메라 렌즈를 고정시킨 상태에서 영상을 취득하므로 플랫 패케이지 아이씨의 높이에 따라서 취득된 플랫 패케이지 아이씨의 영상이 선명하지 못한 경우가 발생하여 이러한 경우에 위치결점 및 리드검사의 정밀도가 떨어지는 문제점이 있었다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electronic component inspection device. The image of the flat package IC obtained according to the height of the flat package IC is obtained by acquiring an image while the CD camera lens is fixed without considering the height of the flat package IC. There was a problem that this was not clear, in this case there was a problem that the accuracy of the position defect and the lead inspection falls.

본 발명은 이와같은 종래장치의 문제점을 감안하여 장착하고자 하는 플랫 패케이지 아이씨들의 각각의 높이에 따라 씨씨디 카메라 렌즈의 촛점거리를 자동으로 변화시킴으로서 선명한 플렛 패케이지 아이씨의 영상을 취득하여 위치결정 및 리드검사의 정밀도를 향상시키는 전자부품 검사장치를 창안한 것이다.In view of the problems with the conventional apparatus, the present invention automatically changes the focal length of the CD camera lens according to each height of the flat package ICs to be mounted, thereby acquiring a clear flat package IC image and positioning and An electronic component inspection device was developed to improve the accuracy of lead inspection.
