Abstract: 본 발명은 전자제품 PCB의 회로검사를 하는 장치에 관한 것이다.일반적으로 전자제품에 사용되는 PCB의 회로검사 방법은 전기적인 신호로 검사하는 방법과 눈으로 검사하는 방법을 병행하고 있다. 전기적인 신호로 검사하는 방법은 두 가지 종류로 구분되는데 하나는 PCB에 조립된 부품에 미세 신호를 인가하여 부품의 전압,전류특성을 읽어서 판단하는 ICT(In Circuit Test)검사와, PCB에 실제 사용되는 전압을 인가하여 완전 조립된 제품을 소비자가 직접 사용하는 것과 동일한 상태가 되도록 Simulation하여 ICT검사로 불량을 검출할 수 없는 부품(IC, Micom등)을 검사하는 FCT 검사방법이 있다. 이와 같이 눈으로 검사하는 공정, ICT 검사공정, FCT 검사공정 3단계에 검사자 및 검사장비를 투입함으로써 생산성이 떨어지고 비용이 상승 된다. 특히 FCT검사는 PCB 전 모델을 검사할 수 있게 표준화가 되어 있지 않아서 생산하고 있는 모델의 PCB에 대응하는 전용장비를 전부 구비해야 하므로 더욱 많은 문제점을 안고 있다. 전기적인 신호로 검사할 수 없는 부품을 검사자가 육안으로 검사하는 방식도 품질관리에 문제가 되고 있다. 따라서 컴퓨터와 CCD 카메라를 이용하여 PCB 이미지를 분석하여 눈으로 검사하는 항목을 대신하고 ICT(In Circuit Test) 검사용 하드웨어를 구축하여 개별의 부품 특성을 검사하며 FCT(Function Circuit Test)검사는 전 모델의 PCB를 검사할 수 있도록 입력조건, 측정조건 등을 발명하여 표준화시킨다. 이 결과 물로 이미지검사, ICT검사, FCT검사를 하나의 공정에서 하나의 장비로 검사하여 생산성 향상, 비용절감, 품질을 향 상시키는데 목적이 있는 발명품이다.

Abstract: 철심형 코어를 갖는 리니어 모터는 자성 부재인 코어의 치, 슬롯과 영구 자석간의 상호작용으로 인하여 발생하는 코깅력(cogging force)을 가지고 있다. 이러한 코깅력은 모터가 구동할 때 이동자에 진동을 유발시키고 힘의 불균형을 불러일으킨다. 특히 큰 추력을 얻기 위하여 다수의 이동자를 직ㆍ병렬로 배치하는 경우에는 코깅력 또한 매우 커지게 되어 성능에 치명적인 악영향을 끼치게 된다. 정밀 구동이 요구되는 모터의 성능 저하를 불러일으키는 코깅력을 없애기 위하여 치와 슬롯의 크기 및 모양에 변화를 주거나 이동자 사이의 간격에 변화를 주는 등의 방법들이 연구되고 있다. 하지만 기존에 제안된 방법들은 코어의 치와 슬롯의 형상에 변화를 주어 추력을 감소시키는 부작용이 있거나, 코깅력을 없애기 위하여 반드시 다수의 이동자를 일정한 간격으로 배치해야하는 구조상의 단점이 존재한다. 본 발명에서는 코깅력을 하드웨어 상에서 근본적으로 제거하고자, 영구 자석의 자극 피치(pole pitch)를 τ p 라고 하고 U-V-W 3상 코일을 한 단위로 하였을 때, 코일 한 단위와 다른 단위의 간격을 1/3×τ p (전기각 60°)씩 총 3쌍의 코일 단위를 하나의 코어 내에 구비함으로써 각각의 코일 단위에서 발생하는 총 3쌍의 코깅력을 합쳤을 때 결과적으로 서로 상쇄되어지도록 구성한다. 본 발명에서 제안하는 코어(이하 단측식 코어)를 구비한 리니어 모터는 코깅력의 완전한 제거가 가능해지고 아무리 많은 코어를 직ㆍ병렬로 구비하여도 코깅력이 존재하지 않는 장점을 가진다. 또한 단측식 코어를 양쪽으로 대칭이 되도록 배치한 것과 유사한 모양의 코어(이하 양측식 코어)는 작은 부피의 코어로써 보다 큰 추력 발생이 가능하여진다.
