제2도에 나타내 보인 본 고안에 따른 음극선관의 형광막 현상장치(10)는 캐리어(30)의 헤드에 장착되어 패널(P)의 전면에 위치되는 것으로서, 노즐지지판(11a)에 복수개의 분사노즐(11)이 배열설치되고, 상기 각 분사노즐(11)은 메니홀더(12)의 상부와 연결관(12a)에 의해 연결되며, 상기 메니홀더(12)의 일측에는 제1솔레노이드밸브(13a)가 설치된 공급관(13)이 연결된다.The fluorescent film developing apparatus 10 of the cathode ray tube according to the present invention shown in FIG. 2 is mounted on the head of the carrier 30 and is positioned on the front of the panel P, and a plurality of sprays are applied to the nozzle support plate 11a. The nozzles 11 are arranged and arranged, and each of the injection nozzles 11 is connected to the upper part of the manifold 12 by a connecting pipe 12a, and the first solenoid valve 13a is connected to one side of the manifold 12. Supply pipe 13 is installed is connected.
여기에서 상기 공급관(13)은 도면에 도시되어 있지 않으나 세정수 펌프의 토출관과 연결된다.Here, the supply pipe 13 is connected to the discharge pipe of the washing water pump, although not shown in the drawing.
그리고 상기 메니홀더(12)의 하부에는 본 고안의 특징에 따라 드레인관(15)이 설치되고 이 드레인관(15)에는 상기 제1솔레노이드밸브(13a)와 역으로 동작하는 제2솔레노이드밸브(15a)가 설치된다.In addition, a drain pipe 15 is installed in the lower portion of the manifold 12 in accordance with a feature of the present invention, and the drain pipe 15 has a second solenoid valve 15a that operates in reverse with the first solenoid valve 13a. ) Is installed.
이와 같이 구성된 본 고안에 다른 음극선관의 형광막 현상장치(10)의 작동을 설명하면 다음과 같다.The operation of the fluorescent film developing apparatus 10 of another cathode ray tube according to the present invention configured as described above is as follows.
노광작업이 완료된 패널(P)이 캐리어(30)에 의해 이동되어 현상장치의 전면에 위치하게 되면 상기 제1솔레노이드밸브(13a)가 열려 상기 공급관(13)으로 부터 현상수가 메니홀더(12)에 공급된다.When the panel P, in which the exposure operation is completed, is moved by the carrier 30 and positioned at the front of the developing apparatus, the first solenoid valve 13a is opened, and the developing water from the supply pipe 13 is transferred to the manifold 12. Supplied.
이때에 상기 메니홀더(12)의 드레인관(15)에 설치된 제2솔레노이드밸브(15a)는 제1솔레노이드밸브(13a)가 열림과 동시에 닫히게 된다.At this time, the second solenoid valve 15a installed in the drain pipe 15 of the manifold 12 is closed simultaneously with the opening of the first solenoid valve 13a.
그리고 상기 메니홀더(12)에 공급된 현상수는 노즐지지판(11a)에 설치된 분사노즐(11)을 통하여 패널의 내면에 동일 압력으로 분사되어 형광막을 세정하게 된다.The developing water supplied to the manifold 12 is sprayed at the same pressure on the inner surface of the panel through the spray nozzle 11 installed on the nozzle support plate 11a to clean the fluorescent film.
이와 같은 작동으로 패널(P)내면의 형광막 세정이 완료되게 되면 상기 공급관(13)의 제1솔레노이드밸브(13a)가 닫히는 동시에 드레인관(15)의 제2솔레노이드밸브(15a)가 열려 공급관(15)으로부터 현상수의 공급이 중단되는 동시에 메니홀더(12)내부의 현상수가 드레인관(15)을 통해 외부로 배출되게 된다.When the fluorescent film cleaning on the inner surface of the panel P is completed by such an operation, the first solenoid valve 13a of the supply pipe 13 is closed and the second solenoid valve 15a of the drain pipe 15 is opened to supply the supply pipe ( The supply of developing water from 15) is stopped, and the developing water inside the manifold 12 is discharged to the outside through the drain pipe 15.
따라서 상기 공급관(15)으로부터 현상수의 공급이 중단됨과 동시에 분사노즐(11)로부터 현상수의 분사가 정지되게 되어 종래와 같이 공급관으로부터 현상수의 공급이 중단되어도 메니홀더(12) 또는 연결관 내부의 잔여압에 의해 현상수가 공급되는 것을 방지할 수 있으며 나아가서는 상기 잔여압으로 분사되는 현상수에 의해 패널(P)내면의 형광막 현상이 불균일하게 이루어지는 것을 방지할 수 있다.Therefore, the supply of the developing water from the supply pipe 15 is stopped and the injection of the developing water from the injection nozzle 11 is stopped, so that the supply of the developing water from the supply pipe as in the prior art is carried out in the manifold 12 or the connection pipe. The developing water can be prevented from being supplied by the residual pressure of the film, and further, the development of the fluorescent film on the inner surface of the panel P can be prevented from being made uneven by the developing water injected at the residual pressure.
이와 같이 본 고안 음극선관의 형광막 현상장치는 형광막이 형성된 패널 내면에 균일한 압력으로 현상수를 분사함과 동시에 세정장치내의 잔여압에 의해 현상수가 공급되는 것을 방지하여 형광막 현상에 따른 불량을 대폭 줄일 수 있는 이점을 가진다.As described above, the fluorescent film developing apparatus of the cathode ray tube of the present invention sprays developing water at a uniform pressure on the inner surface of the panel on which the fluorescent film is formed, and at the same time, prevents the developing water from being supplied by the residual pressure in the cleaning apparatus, thereby preventing defects caused by the phenomenon of the fluorescent film.
