본 발명은 액정모니터용 내부케이스의 나사홀 불량검사방법에 관한 것으로서, 이를 보다 상세히 설명하자면 액정모니터용 내부케이스에 형성되는 다수개의 나사홀을 자동으로 정밀 검사하여 나사홀에 대한 불량 유,무를 보다 신속하고 용이하게 검출함은 물론 그 작업시 인력의 낭비를 막아 생산성의 향상과 제품의 불량 납품을 미연에 예방하여 줄 수 있도록 함에 그 목적을 가지는 것이다.The present invention relates to a screw hole defect inspection method of the inner case for the liquid crystal monitor, to describe in more detail the automatic inspection of a plurality of screw holes formed in the inner case for the liquid crystal monitor to examine the presence or absence of defects on the screw hole Its purpose is to be able to detect quickly and easily, as well as to prevent waste of manpower during its operation, thereby improving productivity and preventing defective delivery of products.

일반적으로 액정모니터는 그 내부로 백라이트가 설치된 내부케이스가 설치되는데, 이때 상기 내부케이스의 표면으로 외부케이스 또는 각종 전자장치가 설치될 수 있도록 다수개의 나사홀을 형성하게 된다.In general, a liquid crystal monitor is provided with an inner case having a backlight installed therein, wherein a plurality of screw holes are formed on the surface of the inner case so that an outer case or various electronic devices can be installed.

즉, 액정모니터용 내부케이스는 그 전방부로 백라이트가 설치됨과 동시에 그 외주와 후방으로 외부케이스나 각종 전자장치가 결합나사로 상호 결합될 수 있도록 다수개의 나사홀을 형성한다.That is, the inner case for the liquid crystal monitor forms a plurality of screw holes so that the backlight is installed at the front portion thereof and the outer case or the various electronic devices can be mutually coupled with the coupling screws at the outer circumference and the rear thereof.

따라서 상기 내부케이스에 형성된 나사홀은 외부케이스 또는 각종 전자장치를 설치함에 있어 매우 중요한 부분으로, 만약 내부케이스에 형성된 나사홀이 불량일 경우 외부케이스는 물론 각종 전자장치가 안전하게 내부케이스에 결합설치될 수 없음은 물론 액정모니터의 불량을 초래하게 되는 크나큰 폐단을 가지게 된다.Therefore, the screw hole formed in the inner case is a very important part in installing the outer case or various electronic devices, and if the screw hole formed in the inner case is bad, the outer case as well as the various electronic devices are safely installed in the inner case. Of course, there is a huge closure that leads to a defect of the LCD monitor.
