The lifting platforms 183a, 183b, and 183c are lowered, and at this time, the pressure plates 189a, 189b, and 189c press the tabs P1 of the LCD panel P so that the tabs P1 and PCB boards 163a, 163b, 163c) comes into intimate contact (see Fig. 5 [c]).

위와 같은 일련의 과정을 통해 검사대(16)에 거치된 엘씨디 패널(P) 및 피씨비 보드(163a,163b,163c)와 백라이트(162)는 하나의 엘씨디 모듈을 구현하는 것이며, 엘씨디 패널(P)에 장착된 탭(P1)가 이상이 없을 경우에는 피씨비 보드(163a,163b,163c)의 구동 프로그램에서 정상적인 신호값이 송출되고 위 신호를 전송받은 검사 유니트(미도시됨.)의 프로그램 보드(미도시됨.)가 백라이트(162)를 점등시켜 주도록 함으로써 엘씨디 패널(P)에 장착된 탭(P1)의 이상유무를 검사하게 되는 것이다.The LCD panel (P) and PC boards (163a, 163b, 163c) and the backlight 162 mounted on the inspection table 16 through the above series of processes implement one LCD module, and the LCD panel (P) If the mounted tap P1 is intact, the program board of the inspection unit (not shown) that receives a normal signal value from the drive programs of the PCB boards 163a, 163b, and 163c and receives the above signal is not shown. By turning on the backlight 162, it is to check the abnormality of the tab (P1) mounted on the LCD panel (P).

엘씨디 패널(P)의 탭(P1)에 대한 검사가 완료된 다음 기동 스위치를 조작하면 승강 실린더(184a,184b,184c)의 승강 작동에 의해 승강대(183a,183b,183c)가 승강하여 가압 플레이트(189a,189b,189c)에 의한 엘씨디 패널(P)의 탭(P1) 및 피씨비 보드(163a,163b,163c)의 접촉상태가 해제되고, 이송 실린더(187a,187b,187c)의 작동에 의해 이송 블럭(186a,186b,186c)이 후진하게 되며, 위 상태에서 엘씨디 패널(P)을 검사대(16)로부터 분리·제거하면 엘씨디 패널(P)의 탭(P1)에 대한 검사작업이 마무리되는 것이다.When the start switch is operated after the inspection of the tab P1 of the LCD panel P is completed, the lifting platforms 183a, 183b and 183c are raised and lowered by the lifting operation of the lifting cylinders 184a, 184b and 184c to pressurize the pressure plate 189a. The contact state of the tab P1 of the LCD panel P and the PCB boards 163a, 163b, and 163c by the 189b and 189c is released, and the transfer block (187a, 187b, 187c) is released. 186a, 186b, and 186c are reversed, and when the LCD panel P is separated and removed from the inspection table 16 in the above state, the inspection work on the tab P1 of the LCD panel P is completed.

본 발명에서 제시하는 엘씨디 패널 탭 검사장치는 엘씨디 패널을 거치한 후 기동 스위치를 조작하면 엘씨디 패널의 탭에 대한 이상유무를 자동으로 검사하여 줄 수 있도록 한 것으로, 소규격의 엘씨디 패널에 대한 검사에 유용하게 사용할 수 있으며, 이동대차의 위치를 가변시킬 수 있도록 함으로써 다양한 규격의 엘씨디 패널에 대한 검사작업에 탄력적으로 사용할 수 있는 등의 효과가 있다.The LCD panel tap inspection device proposed by the present invention is to allow the LCD panel tab to be automatically inspected for abnormalities on the tabs of the LCD panel when the start switch is operated after passing through the LCD panel. It can be usefully used, and by varying the position of the moving cart, there is an effect such that it can be used flexibly for inspection work on LCD panels of various standards.

또한, 본 발명은 엘씨디 패널의 탭에 대한 이상유무의 검사를 단시간 내에 완료할 수 있도록 함으로써 생산성을 향상할 수 있을 뿐만 아니라 검사에 따른 인력 소요를 최소화할 수 있도록 함으로써 궁극적으로는 엘씨디 패널의 제조에 따른 생산원가를 절감할 수 있는 등 본 발명은 그 기대되는 효과가 실로 유익한 발명이다.In addition, the present invention can not only improve the productivity by allowing the inspection of the abnormality of the tab of the LCD panel in a short time, but also to minimize the manpower requirements due to the inspection, ultimately in the manufacture of the LCD panel The present invention, such as to reduce the production cost according to the invention is the invention that the expected effect is really beneficial.
