It is preferable to form the mixed color preventing grooves 34 at predetermined depths between the portions 31.

이하, 상기와 같이 일실시예에 따라 구성되는 본 발명의 노즐장치를 제작 및 조립하는 단계를 설명하면 다음과 같다.Hereinafter, the steps of manufacturing and assembling the nozzle apparatus of the present invention configured according to one embodiment as described above are as follows.

노즐부(20)는 상측 중앙부를 기준으로 서로 대접되는 형태로 제 1노즐부(20a) 및 제 2노즐부(20b)를 제작하며, 각각의 노즐부(20a)(20b)에는 소정의 간격마다 반요홈의 노즐(31)을 다수 가공하되, 하측에는 좁은 직경의 직선부로 형성하고 상측부는 직경이 다소 넓은 형태로 가공하며, 상기 노즐(31)의 좁은 직경부와 넓은 직경이 접하는 부분에는 형광액의 흐름을 유도하기 위한 형광액 유도홈(33)을 가공한다. The nozzle unit 20 manufactures the first nozzle unit 20a and the second nozzle unit 20b in a form in which the nozzle unit 20 is welded to each other based on the upper center portion, and the nozzle units 20a and 20b are formed at predetermined intervals. A plurality of nozzles 31 of the recess groove are processed, but the lower side is formed of a straight line having a narrow diameter, and the upper side is processed into a somewhat wider shape, and the narrow portion of the nozzle 31 is in contact with the wide diameter of the fluorescent solution. Process the fluorescence guide groove 33 to induce the flow of.

이렇게 노즐(31)의 내부를 육안으로 확인하면서 가공함으로써, 미세한 노즐(31) 가공이 가능하며, 종래에는 불가능했던 형광액 유도홈(33)의 가공도 가능하며, 노즐(31) 내부의 연마가공 및 폴리싱 가공, 래핑가공도 가능하여 양호한 노즐(31)을 제공할 수 있다.By processing the inside of the nozzle 31 with the naked eye as described above, the fine nozzle 31 can be processed, and the fluorescent liquid guide groove 33 can also be processed. And polishing and lapping can also be performed, and the favorable nozzle 31 can be provided.

또한, 탱크부(20)는 제 1탱크부(20a)와 제 2탱크부(20b)로 각각 별도 제작하되, 제 1탱크부(20a)와 제 2탱크부(20b)의 내측에는 길이방향으로 길게 반요홈 형태로 이루어져 서로 대접되는 형광액 충진부(21)를 각각 형성 가공하고, 그 외의 면은 서로 밀착 접하도록 밀착면(22)을 형성한다. In addition, the tank portion 20 is separately manufactured as the first tank portion 20a and the second tank portion 20b, respectively, in the longitudinal direction inside the first tank portion 20a and the second tank portion 20b. Forming and processing each of the fluorescent liquid filling portion 21 is formed in a long recessed shape and abutted with each other, the other surface to form a close contact surface 22 to be in close contact with each other.

상기와 같이 제작된 제 1탱크부(20a)에는 제 1노즐부(30a)를 체결구(35)에 의해 견고히 체결하며, 마찬가지로 제 2탱크부(20b)에는 제 2노즐부(30b)를 체결구(35)에 의해 견고히 체결한다. 그리고, 이렇게 체결된 각각의 탱크부(20a)(20b) 및 노즐부(30a)(30b)의 밀착면(22)(32)을 서로 접하도록 하여 탱크부(20) 측이 지지구(10)의 삽입홈(11)에 삽입되도록 하고, 상기 지지구(10)의 외측에서는 삽입홈(11) 측으로 체결구(12)를 체결하고, 상측에서는 상기 탱크부(20a)(20b)와 나사 등의 체결구(13)로 체결하여 탱크부(20)와 노즐부(30)가 지지구(10)에 견고히 지지되도록 한다.The first nozzle part 20a is firmly fastened to the first tank part 20a manufactured as described above by the fastener 35, and similarly, the second nozzle part 30b is fastened to the second tank part 20b. It is fastened firmly by the sphere 35. Then, the tanks 20 side is supported by the supporter 10 so that the tanks 20a and 20b and the contact surfaces 22 and 32 of the nozzle units 30a and 30b are thus contacted with each other. The fasteners 12 are inserted into the insertion grooves 11 of the support grooves 10, and the fasteners 12 are fastened toward the insertion grooves 11 at the outer side of the support 10, and the tanks 20a and 20b and the screws are upwards. The fastener 13 is fastened so that the tank 20 and the nozzle 30 are firmly supported by the support 10.

이렇게 결합된 본 발명의 노즐장치(N) 하부에 패널(1)을 재치하고, 하나의 형광액, 즉, R 형광액을 상기 패널(1)에 도포하게 되는 바, 도면에는 도시되지 않은 공지의 형광액 토출장치에 의해 형광액을 주입관(12)을 통해 탱크부(20)의 형광액 충진부(21)로 서서히 충진시킨다. The panel 1 is placed on the lower part of the nozzle apparatus N of the present invention thus coupled, and one fluorescent material, that is, an R fluorescent liquid is applied to the panel 1, and thus, a known device not shown in the drawings. The fluorescent liquid is gradually filled by the fluorescent liquid discharge device into the fluorescent liquid filling part 21 of the tank part 20 through the injection tube 12.

그리고, 충진이 어느 정도 되면, 2차 가압을 하여 형광액을 가압하여 토출하게 되며, 형광액 충진부(21)에 충진된 형광액은 하부의 노즐부(30)의 노즐(31)을 통해 패널(1)에 도포되기 시작하며, 서서히 이동하는 노즐장치(N)에 의해 1피치 간격마다 동일 형광액이 균일하게 도포된다.Then, when the filling is to some extent, the secondary pressure is applied to pressurize and discharge the fluorescent liquid, and the fluorescent liquid filled in the fluorescent liquid filling part 21 is panel through the nozzle 31 of the lower nozzle part 30. The same fluorescent liquid is uniformly applied every one pitch interval by the nozzle apparatus N which starts to apply to (1) and is gradually moved.

이때, 노즐(31) 내부가 유선형으로 완만하게 연삭가공됨으로써, 형광액의 분출이 용이하며, 아울러, 형광액 유도홈(33)에 의해 형광액의 흐름이 노즐(31)의 하부측을 일시적으로 막게 되는 문제가 발생하지 않게 된다.At this time, by gently grinding the inside of the nozzle 31 in a streamlined manner, the ejection of the fluorescent liquid is easy, and the flow of the fluorescent liquid is temporarily directed to the lower side of the nozzle 31 by the fluorescent liquid guide groove 33. The problem of being prevented will not occur.

이렇게 동일 형광액을 다수의 노즐(31)에 의해 여러 반복작업을 수행하여 도포작업을 마친 후, 패널(1)을 이동하여 다른 형광액, 즉, G 형광액을 도포하기 위한 노즐장치(N)의 하부에 패널(1)을 재치한 후, 상기 R 형광액이 도포된 옆 라인을 따라 상기와 같은 도포작업을 수행하게 되며, 마찬가지로 B 형광액의 도포작업도 수행하여 형광액의 도포작업을 마무리한다.In this way, after repeating the coating work by performing the same repetitive work by the plurality of nozzles 31 with a plurality of nozzles 31, the nozzle 1 for moving the panel 1 to apply another fluorescent solution, that is, a G fluorescent solution (N) After the panel 1 is placed on the lower portion of the panel 1, the coating operation is performed along the side line on which the R phosphor is applied, and similarly, the B phosphor is applied to finish the phosphor coating. do.

그리고, 작업도중 노즐(31)이 막히거나 불량이 발생할 경우는 탱크부(20)와 노즐부(30)를 분리하여 내부를 청소하여 간편하게 수리할 수도 있다.In addition, when the nozzle 31 is clogged or defective during the operation, the tank unit 20 and the nozzle unit 30 may be separated to clean the inside, and may be easily repaired.

이상에서 설명한 것은 본 발명의 일 실시 예를 들어 설명한 것에 불과한 것으로써, 본 발명은 상기한 실시 예에 한정되지 않고, 이하의 특허청구의 범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능한 범위까지 본 발명의 기술적 사상이 미친다고 할 것이다.
