Abstract

프린트 기판에 부품이 삽입되었는지의 여부를 판단하는 기준이되는 미삽 검사 데이타 베이스를 자동으로 생성하기 위하여 시각장치를 이용하여 삽입전의 프린트 기판을 촬영하고, 각 홀의 데이타 베이스를 추출하여 각 홀에 해당되는 블록을 검출한 후, 그 블록의 기준홀을 중심으로 상대좌표를 산출하고, 상대좌표, 블록번호, 기타 인식에 필요한 값들로 데이타 베이스를 생성하고, 상기 데이타 베이스를 상기 프린트 기판의 기준홀에 대한 좌표로 변환하여 저장한다.In order to automatically generate an uninserted inspection database which is a standard for determining whether a part is inserted into a printed board, the printed board before the insertion is photographed using a visual apparatus, and the database of each hole is extracted and After detecting the block, a relative coordinate is calculated based on the reference hole of the block, a database is generated with relative coordinates, block numbers, and other values necessary for recognition, and the database is compared to the reference hole of the printed board. Convert to coordinates and save.
