본 고안은 음극선관의 제조공정에 있어서, 패널면에 형성된 형광막의 상층에 중간막을 도포한 다음, 이송중에 도포된 중간막을 건조시키는 벌브 건조장치에 관한 것이다.The present invention relates to a bulb drying apparatus for applying an intermediate film to the upper layer of the fluorescent film formed on the panel surface in the manufacturing process of the cathode ray tube, and then drying the applied intermediate film during transport.

음극선관의 제조에 있어서, 특히 흑백브라운관의 제조공정을 제1도로서 설명하면 다음과 같다.In the production of the cathode ray tube, the manufacturing process of the black-and-white brown tube will be described with reference to FIG.

벌브 세정공정에서 패널과 퍼늘, 그리고 넥크를 일체로 접합시켜 만들어진 벌브의 내면이 불산과 순수로 깨끗이 세척되고, 다음에 형광체 침전공정에서 패널의 내측면에 형광막이 침전 형성되며, 이 형광막은 열풍에 의해 건조되어 다음의 중간막 도포공정으로 이송된다.In the bulb cleaning process, the inner surface of the bulb formed by integrally joining the panel, perm, and neck is cleaned with hydrofluoric acid and pure water, and then, in the phosphor precipitation process, a phosphor film is formed on the inner surface of the panel, and the phosphor film is exposed to hot air. It is dried and conveyed to the next interlayer coating process.

중간막 도포공정에서 형광막의 상층으로 래커가 도포되며, 이 래커는 이후에 도포되는 알미늄 증착막이 형광막을 손상시키지 않게 한다.Lacquer is applied to the upper layer of the fluorescent film in the interlayer coating process, so that the later deposited aluminum deposited film does not damage the fluorescent film.

중간막이 도포된 벌브는 패널면을 제외한 내측면에 잔류하는 래커를 세정하고 건조시킨 다음, 내장흑연 도포공정으로 보내진다.The bulb coated with the interlayer is washed with dry lacquer remaining on the inner surface except the panel surface, dried and then sent to the embedded graphite coating process.

내장흑연은 벌브와 네크가 접합되는 부위에 국부적으로 도포되는 것이며, 이렇게 내장흑연이 도포된 벌브는 다시 건조된 후, 알미늄 증착공정으로 보내진다.Built-in graphite is locally applied to the site where the bulb and the neck are joined, and the bulb coated with the built-in graphite is dried again and then sent to an aluminum deposition process.

알미늄이 중착된 벌브는 소성로에서 소성되고, 이어서 형광막의 양부를 검사받은 다음, 전자총이 네크에 봉입되고, 배기, 밀봉공정을 거쳐 음극선관으로 완성된다.The aluminum-encapsulated bulb is fired in a kiln, followed by inspection of the fluorescence film, and then the electron gun is sealed in the neck, and exhausted and sealed to complete the cathode ray tube.

상술한 음극선관의 제조공정에서, 중간막이 도포된 벌브는 별도의 건조기에 의해 열풍 건조됨이 통상이나, 이방식은 건조기의 설치공간을 필요로 하고, 건조에 소요되는 시간이 길어서 작업능률의 향상에 장애로 되는 문제점을 갖는다.In the manufacturing process of the cathode ray tube described above, the bulb coated with the intermediate film is usually hot-air dried by a separate dryer, but this method requires an installation space for the dryer, and the time required for drying is long, thereby improving work efficiency. There is a problem that becomes an obstacle.

본 고안은 음극선관의 제조공정에서 각각의 벌브가 컨베이어에 의해 공정 별로 이송되고 있음에 착안하여 완성된 것으로서, 그 목적으로 하는 바는 전기한 컨베이어의 경로 상에 설치할 수 있는 벌브 건조장치를 제공함에 있다.The present invention was completed in view of the fact that each bulb in the manufacturing process of the cathode ray tube is transported by the conveyor by process, the object is to provide a bulb drying apparatus that can be installed on the path of the electric conveyor. have.

상기 목적에 따라 본 고안은 양측에 입구와 출구가 열려진 덕트와, 이 덕트의 내주면에 대향 배치되는 적어도 1쌍의 적외선 히이터로 구성됨을 특징으로 한다.According to the above object, the present invention is characterized in that it consists of a duct, the inlet and the outlet is opened on both sides, and at least one pair of infrared heaters arranged opposite to the inner peripheral surface of the duct.

상기한 덕트는 벌브에 도포된 중간막이 반송되는 동안에 건조될 수 있는 길이를 갖고, 또 벌브를 반송하기 위한 컨베이어 상에 설치된다.Said duct has a length which can be dried while the intermediate film apply | coated to the bulb is conveyed, and is installed on the conveyor for conveying a bulb.

그러므로 중간막이 도포된 벌브는 상기의 덕트를 지날때, 가열에 의해 건조된다.Therefore, the bulb coated with the interlayer is dried by heating when passing through the duct.

이하, 본 고안의 바람직한 실시예를 첨부도면 제2도를 참조하여 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도면에서 부호(2)는 양측에 입구에 출구가 열려진 덕트이며, 부호(4)는 이 덕트(2)의 내주면에 적어도 1쌍으로 대향 설치된 적외선 히이터이다.In the drawing, reference numeral 2 denotes a duct in which an outlet is opened at an inlet on both sides, and reference numeral 4 denotes an infrared heater provided in at least one pair on the inner circumferential surface of the duct 2.

벌브(6)은 반송컨베이어(8)상에 현수된 캐리어(10)에 의해 반송된다.The bulb 6 is conveyed by the carrier 10 suspended on the conveyance conveyor 8.

따라서, 벌브(6)은 반송 중에 상기한 덕트(2)를 통과하면서 적외선 히이터(4)에 의해 가열된다.Therefore, the bulb 6 is heated by the infrared heater 4 while passing through the above-mentioned duct 2 during conveyance.

한편, 벌브(6)의 내면에 도포된 중간막은 래커를 주성분으로 하기 때문에 가열되면 래커에 함유된 시너가 증발하여 중간막이 서서히 고착되기 시작한다.On the other hand, since the interlayer film applied to the inner surface of the bulb 6 has lacquer as a main component, when heated, the thinner contained in the lacquer evaporates, and the interlayer film gradually starts to adhere.

그러므로, 덕트(2)의 길이(L)은 벌브(6)의 반송속도와 건조시간, 그리고 가열온도에 따라 설정하여, 벌브(6)이 덕트(2)를 통과함에 맞추어 중간막이 건조될 수 있는 길이로 하는 것이 좋다.Therefore, the length L of the duct 2 is set according to the conveying speed and drying time of the bulb 6 and the heating temperature, so that the intermediate film can be dried as the bulb 6 passes through the duct 2. It is good to make the length.

또, 덕트(2)는 예시한 실시예와 같이 반드시 직선상으로 연장된 컨베이어(8)에 설치되는 것으로 한정되는 것은 아니다.In addition, the duct 2 is not limited to being installed in the conveyor 8 extended linearly like the illustrated embodiment.

즉, 컨베이어(8)이 커브를 그리거나 또는 S자상으로 우회연장되었다 하더라도 덕트(2)를 전기한 컨베이어(8)의 연장형태와 동일하게 만곡시켜 설치할 수도 있고, 필요하다면 2개소 이상에 나누어 배열하여도 무방하다.That is, even if the conveyor 8 is curved or detoured in an S-shape, the duct 2 may be curved and installed in the same manner as the extension type of the conveyor 8 in which the conveyor 8 is installed. You may.

이와 같은 본 고안의 건조장치는 종래와는 달리 반송용 컨베이어 상에 설치되는 것이므로 별도의 설비공간이 필요치 않고, 또 벌브의 이송 중에 중간막을 건조시키는 것이므로 공정수와 시간을 단축할 수 있음과 동시에, 인력을 절감할 수 있는 이점이 있으며, 또 건조 종료 즉시 내장흑연 도포공정에 투입될 수 있어서 음극선관의 제조에 소요되는 시간이 단축되어 생산성을 높일 수 있는 장점을 갖는다.Since the drying apparatus of the present invention is installed on a conveyor for conveyance unlike the related art, a separate installation space is not required, and since the intermediate film is dried during the transport of the bulb, the number of processes and time can be shortened, There is an advantage to reduce the manpower, and can be added to the built-in graphite coating process immediately after the end of drying has the advantage that the time required for manufacturing the cathode ray tube is shortened to increase the productivity.
