Abstract

This paper describes a system implementation for the automatic inspection on the ventilating electronic device based on the reliability improvement. To be enhancement, the inspection error is minimized by the automatic inspection system on the ventilating apparatuses against the manual inspecting system. The system consists of the control system, software structure and monitoring system to be scanning the inspection processing. The inspection system for reliability improvement is evaluated in Gage Repeatability and Reproducibility. The experimental results are improved about 2 times inspecting speed, measured error ${\pm}0.02V$, effectiveness of discriminating performance 15%, missing probability 17% and false alarm probability 12% respectively in comparing with the manual inspection based on the wind pressure sensor. The system will be also improved more by making database and product bar codes for the total quality control system to the effective reliability enhancement in the future.

본 연구는 신뢰성 향상 기반의 송풍전자장치 자동검사 시스템을 구현하기 위한 연구이다. 신뢰성향상을 위해 수동검사 시스템에서 자동검사 시스템은 전자제품 검사의 오류를 최소화한다. 송풍전자장치 자동화 검사 시스템은 제어시스템과 모니터링시스템으로 구성되어 되어 실시간으로 검사결과를 공유한다. 검사시스템의 신뢰성은 Gage R&R 분석기법을 적용하여 평가한다, 평가결과는 수동검사에 비해 풍압센서를 기반으로 검사속도 2배 이상, 측정오차 ${\pm}0.02V$, 판정 능력의 유효성 15%, 누락확률 17%, 허위경보확률 12% 등으로 향상되었다. 따라서 전자제품 자동검사 시스템은 제품 바코드와 연동시켜 데이터베이스화하면 효율적인 신뢰성 향상의 품질관리시스템으로 발전시킬 수 있다.
