Abstract

In this paper, a quality inspection system was developed to identify the defective assembly of connectors used in automobile wiring. For waterproof connectors, an internal seal must be inserted for waterproofing. However, there are cases where it is omitted or double-inserted during production. An automatic inspection jig was designed using photosensors and touch switches to classify good and bad connector components. In the case of the existing visual inspection, 6,400 connectors were inspected when 5 people inspected for 8 hours. However, when using the inspection jig developed under the same conditions, 20,000 pieces were inspected. In other words, the productivity is greatly improved compared to the conventional visual inspection.

본 논문에서는 자동차 배선에 사용되는 커넥터의 조립 불량 상태를 식별하는 품질 검사 시스템을 개발하였다. 방수용 커넥터는 방수를 위하여 내부 Seal을 필수적으로 삽입하여야 하는데 생산 과정에서 누락되거나 이중 삽입되는 경우가 있다. 이를 구분하기 위하여 포토센서와 터치스위치를 사용하여 자동화 검사 지그를 설계하였다. 기존 육안검사의 경우 5인이 하루 8시간 검사하였을 때 6,400개의 커넥터를 검사하였으나 개발된 검사 지그를 사용할 때는 20,000개를 검사하므로 기존의 육안 검사와 비교하여 생산성이 크게 향상되었다.
