본 발명은 TV 생산공정중의 PCB 자동조정장치에 관한 것으로 특히 TV 화면의 상·하폭을 조정하기 위해 변압기를 이용한 수직크기(V-SIZE) 자동조정장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic PCB adjusting device during a TV production process, and more particularly, to a vertical automatic adjusting device (V-SIZE) using a transformer to adjust the upper and lower widths of a TV screen.

종래에는 TV PCB 생산공정을 조정하는데 있어 작업자가 동작지그용 TV에 사내신호 패턴을 수신하여 TV화면에 나타난 상태에서 TV 화면을 보고 상·하폭을 가변하여 일정한 크기로 조정을 하고 있었으나, 이럴 경우에는 TV 화면을 직접 보고 작업을 수행함에 따라 작업자의 시각이 필요해져 작업능률이 떨어지므로 생산성이 저하되어 기종마다 별도의 동작검사용지그(JIG)를 필요로 하였던 것이다.Conventionally, in adjusting the TV PCB production process, the operator receives the in-house signal pattern on the TV for the operation jig and adjusts it to a certain size by changing the upper and lower widths while watching the TV screen in the state shown on the TV screen. As the user directly sees the TV screen and needs to see the operator's vision, the work efficiency decreases, thus reducing productivity and requiring a separate operation test jig for each model.

따라서 본 발명은 상기한 제반 문제점을 해결하기 위하여 안출한 것으로서, 디플렉션 요크 더미의 수직전압을 트랜스를 통해 10분의 1로 감소시키고 부하저항의 양단전압을 A/D변환시켜 컴퓨터의 제어에 의해 모터를 회전되게 하여 PCB의 조정점을 일정한 값으로 조정할 수 있도록 하여 작업능률을 향상시키고 각 기종마다 사용되는 별도의 동작검사용 지그가 필요 없는 장치를 제공하는데 있다.Accordingly, the present invention has been made to solve the above-mentioned problems, the vertical voltage of the deflection yoke pile is reduced to one tenth through the transformer and A / D conversion of the voltage across the load resistance by computer control By rotating the motor to adjust the adjustment point of the PCB to a certain value to improve the work efficiency and to provide a device that does not require a separate operation test jig used for each model.

이를 첨부도면에 의해 설명한다.This will be described with reference to the accompanying drawings.

The deflection yoke pile 10 for deflecting the electron beam is connected to the pin board 70 'through a transformer TS primary side coil L 1 , but is connected to the pin board 70' through a separate cable to the PCB 70. A) for connecting the FBT dummy 90 connected to the connector and stabilizing the transformer (TS) two-sided coil (L 2 ) with a resistor (R) and a signal, and converting an analog output voltage into digital. PCB 70 is controlled by connecting the computer 40 to the computer 40 controlling the data operation and the whole part through the / D changer 30 and controlling the motor 50 'through the motor driver 50.

이하 첨부된 도면에 의해 본 발명의 작용 및 효과를 설명한다.Hereinafter, the operation and effects of the present invention will be described with reference to the accompanying drawings.

먼저 조정하고자 하는 대상체인 PCB(70)에 RF신호공급기(60)로 부터 조정에 필요한 채널 주파수신호를 공급하고 상부의 핀과 PCB(70)와의 접촉을 통해서 각종 신호공급 및 신호를 추출하는 핀보드(70')를 통해 전원공급기(80)에서 발생된 동작전원을 PCB(70)에 공급하며 상기 PCB(70)상에서 분리되어 별도의 케이블을 통해 PCB(70)와 연결시키는 FBT 더미(90)가 핀보드(70')를 통해 PCB(70)와 연결된다. 따라서 상기 PCB(70)에서 추출된 신호가 핀보드(70')와 디플렉션 요크 더미(10)를 경유하여 TV 상에서 CRT 전자빔을 편향시켜 수직크기(V-SIZE) 자동조정시에 이용되는 수직편향(VD) 전압을 변압기(TS) 1차측 코일(L1)에 출력한다.First, a pin board for supplying a channel frequency signal for adjustment from the RF signal supplier 60 to the PCB 70, the object to be adjusted, and extracting various signals and signals through contact between the upper pin and the PCB 70. FBT dummy 90 which supplies the operating power generated from the power supply 80 to the PCB 70 through the 70 'and is separated on the PCB 70 and connected to the PCB 70 through a separate cable It is connected to the PCB 70 through the pin board 70 '. Therefore, the signal extracted from the PCB 70 is deflected by the CRT electron beam on the TV via the pin board 70 'and the deflection yoke pile 10 so that the vertical deflection is used for automatic adjustment of the V-size. The voltage (VD) is output to the transformer TS primary side coil L 1 .

이때 상기 변압기(TS)가 1차측코일(L1)에 인가된 수직편향(VD) 전압을 1/10로 감소시켜 2차측 코일(L2)을 통해 출력하여 출력측 부하저항인 저항(R)과 커넥터(20)를 거쳐 1/10로 감소된 출력신호가 안정되어 A/D변환기(30)를 통해 출력된 아날로그전압이 디지탈전압으로 변환되어 컴퓨터(40)에 처리가능한 데이타를 전송한다.At this time, the transformer TS reduces the vertical deflection (VD) voltage applied to the primary coil L 1 to 1/10 and outputs it through the secondary coil L 2 to output an output load resistance resistor R and The output signal reduced to 1/10 through the connector 20 is stabilized so that the analog voltage output through the A / D converter 30 is converted into a digital voltage to transmit the processable data to the computer 40.

따라서 상기 컴퓨터(40)에서 PCB(70)에서 출력된 전압을 비교하여 측정된 전압이 설정된 기준저압 보다 크면 모터드라이버(50)를 통해 모터(50)를 시계방향(CW)으로 회전시켜 PCB(70)의 조정점을 돌려 조정하고 상기 컴퓨터(40)에서 비교된 측정전압이 설정된 기준전압보다 작으면 모터드라이브(50)를 통해 모터(50')를 시계반대방향(CCW)으로 회전시켜 PCB(70)의 조정점을 돌려 조정한 후 상기 컴퓨터(40)에서 비교적 측정전압과 설정된 기준전압이 일치하면 모터드라이버(50)를 통해 모터(50') 구동을 멈추게 하여 PCB(70)의 조정점의 조정을 멈추어 조정을 완료한다.Therefore, when the measured voltage is greater than the set reference low pressure by comparing the voltage output from the PCB 70 in the computer 40 by rotating the motor 50 clockwise (CW) through the motor driver 50 PCB (70) The control point by adjusting the adjustment point of < RTI ID = 0.0 >) < / RTI > and when the measured voltage compared by the computer 40 is smaller than the set reference voltage, the motor 50 ' After adjusting by adjusting the adjustment point of), if the measured voltage and the reference voltage are relatively matched in the computer 40, the driving of the motor 50 'is stopped through the motor driver 50 to adjust the adjustment point of the PCB 70. Stop to complete the adjustment.

상술한 바와같이 본 발명은 디플렉션 요크 더미를 통해 출력되는 PCB의 수직편향(VD)전압을 변압기를 통해 1/10로 감소시켜 컴퓨터의 제어에 의해 모터를 구동하여 PCB의 조정점을 자동으로 정확하게 조정하여 TV PCB 생산공정에서 작업능률을 향상시켜 제품생산성을 증가하고 각 기종마다 별도의 동작검사가 필요없는 유익한 발명이다.As described above, the present invention reduces the vertical deflection (VD) voltage of the PCB output through the deflection yoke pile to 1/10 through a transformer to drive the motor under computer control, thereby automatically correcting the adjustment point of the PCB. It is a profitable invention that improves the work efficiency in the TV PCB production process by adjusting the product productivity and does not require a separate operation test for each model.
