Abstract
칩 마운터의 노즐부의 조명상태를 검사하는 방법에 관한 것으로, 화상 인식 카메라로 부터 노즐의 영상을 입력받고, 상기 영상에서 확산판 영역에 대하여 노즐 중심에서 8방향으로 조도의 분포를 검출하여, 상기 노즐부분의 조도의 평균(NZA(n))과 확산판 부분의 조도의 평균(DFA(n))을 구하고, 상기 노즐 부분의 조도의 평균(NZA(n))의 최대와 최소를 구하여 그 차가 설정범위 이내인가를 판단하여 선정 범위이내가 아니면 불량이라고 판단하고, 상기 확산판 부분의 조도의 평균(DFA(n))의 최대와 최소를 구하여 그 차가 설정범위 이내인가를 판단하여 실정 범위이내가 아니면 불량이라고 판단하며, 상기 노즐 부분의 조도의 평균(NZA(n))과 상기 확산판 부분의 조도의 평균(DFA(n))의 차를 구하여 그 차가 설정범위 이내인가를 판단하여 설정 범위이내가 아니면 불량이라고 판단하고, 상기 단계에서 불량이라고 판단되지 않으면 조명상태 양호를 표시하고, 상기 단계에서 뷸량이라고 판단하면, 불양 부분을 모니터에 표시한다.A method of inspecting an illumination state of a nozzle unit of a chip mounter, the method comprising: receiving an image of a nozzle from an image recognition camera, detecting an illuminance distribution in an eight-direction direction from a nozzle center with respect to a diffuser plate region in the image; The average of the roughness of the portion (NZA (n)) and the average of the roughness of the diffuser plate portion (DFA (n)) are obtained, and the maximum and minimum of the average of the roughness of the nozzle portion (NZA (n)) are obtained and the difference is set. If it is within the selected range, it is determined that it is not within the selected range, and if it is not within the selected range, the maximum and minimum values of the roughness (DFA (n)) of the roughness of the diffuser plate are obtained, and the difference is within the set range. It is judged that the defect is, and the difference between the average of roughness of the nozzle portion (NZA (n)) and the average of the roughness of the diffuser plate portion (DFA (n)) is determined, and it is determined whether the difference is within the setting range. Or bad It said judgment and, if the does not judged to be defective in the above step shows the good lighting condition, and the determination in the step amount byul, and displays the bulyang portion on the monitor.
