Description

브라운관의 특성 자동 검사장치CRT automatic inspection device

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명의 측정구간 표시도, 제2도는 본 발명의 자동 특성 검사장치의 내부 구성도.1 is a view showing the measurement interval of the present invention, Figure 2 is an internal configuration of the automatic characteristic inspection device of the present invention.

Claims (2)

브라운관의 특성 검사장치에 있어서, 측정구간을 3색신호에 따라 캐소드 컷 오프 전류 측정구간(COE2)과 캐소드 최대전류 측정구간(MIK)으로하는 측정구간 수단과, 3색신호 각각의 특성 검사를 위한 각각의 이상유무 판단 처리 회로(100),(200),(300)를 구성하며, 상기 처리회로를 PC(400)에 연결하여 PC에 의해 제품의 양.불 표시를 하도록 한 것을 특징으로 하는 브라운관의 특성 자동 검사장치.In the CRT characteristic inspection apparatus, measuring section means for measuring the cathode cut-off current measurement section (COE2) and the cathode maximum current measurement section (MIK) according to the three-color signal, and each of the three color signals for the characteristic inspection. An abnormality determination processing circuit 100, 200, and 300, and the processing circuit is connected to the PC 400, the characteristics of the CRT, characterized in that the display of the product by the PC to indicate whether or not the product Automatic inspection device. 제1항에 있어서, 3색신호 각각의 이상유무 판단 처리회로는 브라운관에 캐소드 컷 오프 전류 및 최대전류 절환을 위한 릴레이와, 캐소드 전류를 전압으로 바꾸기 위한 전류 검출용 가변저항과, A/D변환기가 내장되고 가변식으로 정격 전류치를 세팅할 수 있는 DVM과, DVM의 세팅전압 이상 일때만 동작하는 릴레이와, 전원부를 각각 연결하여 구성한 것을 특징으로 하는 브라운관의 특성 자동 검사장치.The circuit for detecting abnormality of each of the three color signals includes a relay for switching the cathode cut-off current and the maximum current, a variable resistor for current detection for converting the cathode current into a voltage, and an A / D converter. CVM's built-in and variable variable current rating setting, the relay operating only when the setting voltage of the DVM and the power supply unit, characterized in that the configuration of the CRT. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
