Description

진동식 형광체 코팅장치Vibrating Phosphor Coating Equipment

본 고안은 패널에 형광체를 도포하는 공정에 있어서 스핀방식이 아닌 진동식 형광체 코팅 장치에 관한 것이다.The present invention relates to a vibrating phosphor coating device that is not a spin method in the process of applying a phosphor to a panel.

주지하는 바와 같이 음극선관 제조공정에 있어서 패널에 형광체를 도포하는 것인 바, 이 공정에서는 일반적으로 케리어헤드에 고정된 패널의 내면에 노즐로 분사되는 형광체를 도포하였다.As is well known, a phosphor is coated on a panel in a cathode ray tube manufacturing process. In this step, a phosphor sprayed by a nozzle is applied to an inner surface of a panel fixed to a carrier head.

이러한 종래의 방법을 도 1 의 (가), (나), (다)에서 보였다.This conventional method is shown in (a), (b) and (c) of FIG.

이에서 알 수 있는 바와 같이 종래에는 노즐(101)에 의하여 분사되는 형광체(103)를 패널(102)내면에 도포한 뒤, 약 155°의 각도를 갖는 캐리어헤드(104)에 패널을 고정시킨 뒤, 이를 회전시켜 형광체를 패널내면에 고르게 도포하는 방법이었다.As can be seen in the related art, after the phosphor 103 sprayed by the nozzle 101 is applied to the inner surface of the panel 102, the panel is fixed to the carrier head 104 having an angle of about 155 °. By rotating this, the phosphor was evenly applied to the inner surface of the panel.

그러나 상술한 종래의 방법서는 도 2 의 (가), (나)에서 보는 바와 같이 패널이 회전하면서 코팅되기 때문에 형광체가 코너부에 집중되어 기포가 발생될 수 있으며, 또한 형광체 자체의 비중차에 의해 막두께가 차이가 발생되는 것이었다.However, in the above-described conventional method, since the panel is coated while rotating as shown in FIGS. 2A and 2B, bubbles may be generated by concentrating the phosphor at the corners, and also due to the specific gravity difference of the phosphor itself. The difference in film thickness was to occur.

또한 코너부의 형광액이 건조되어 기포가 발생되어 제품의 품질이 저하되는 문제점이 있었다.In addition, there is a problem in that the fluorescent solution of the corner portion is dried and bubbles are generated to deteriorate the quality of the product.

상술한 문제점을 감안하여 본 고안에서는 형광체 도포과정에서 패널의 내면에 균일한 막두께를 유지하고 형광체의 점도에 따른 도포막의 두께편차를 최소화할 수 형광체 코팅장치를 제공함을 목적으로 한다.In view of the above problems, the present invention aims to provide a phosphor coating apparatus capable of maintaining a uniform film thickness on the inner surface of a panel during a phosphor coating process and minimizing a thickness variation of a coating film according to the viscosity of the phosphor.

도 1 은 종래의 형광체 도포방법을 나타낸 것으로,1 shows a conventional phosphor coating method,

* 도면의 주요 부분에 대한 부호의 설명 *Explanation of symbols on the main parts of the drawings

1 : 형광체2 : 패널1: phosphor 2: panel

3 : 분사노즐4 : 로봇암3: injection nozzle 4: robot arm

5 : 트랜스듀셔5: Transducer

이를 위해 본 고안에서는 형광체를 패널내면에 도포하기 위한 로봇암과, 상하진동력을 제공하기 위한 트래스듀셔를 구비하는 진동식 형광체 코팅장치를 제안한다.To this end, the present invention proposes a vibrating phosphor coating device having a robot arm for applying the phosphor to the inner surface of the panel, and a trassider for providing up and down vibration force.

상술한 본 고안은 형광체의 비중이나 점도 등의 관리가 다소 불균일 하더라도 회전방식보다 관리의 여유가 생길 뿐만 아니라 기포의 발생을 최소화하여 균일한 형광막의 코팅작업이 가능해지는 효과가 있다.The present invention described above, even if the management of the specific gravity, viscosity, etc. of the phosphor is somewhat uneven, there is an effect that not only the management can be afforded more than the rotation method, but also minimize the generation of bubbles to uniform coating of the fluorescent film.

이하 본 고안을 첨부한 도면에 의하여 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 3 의 (가), (나), (다)는 본 고안인 진동식 형광체 코팅장치의 도포과정을 보였다.Figure 3 (a), (b), (c) showed the application process of the vibrating phosphor coating device of the present invention.

이에서 알 수 있는 바와 같이 본 고안은 형광체(1)를 패널(2)의 내면 전체에 도포하기 위한 다수 개의 분사노즐(3)이 구비된 로봇암(4)과,As can be seen from the above, the present invention provides a robot arm 4 equipped with a plurality of injection nozzles 3 for applying the phosphor 1 to the entire inner surface of the panel 2,

패널(2)의 하방에서 상하 진동력을 제공하기 위한 트랜스듀셔(5)로 구성된 것이다.It is composed of a transducer (5) for providing a vibration force up and down under the panel (2).

이상과 같은 본 고안은 우선, 도포공정의 위치에 도달한 패널(2)의 내면에 로봇암(4)이 도면상 패널내면의 좌측 분사위치에 도달하게 되면 분사노즐(3)을 통하여 형광체(1)가 분사하기 시작하며, 점차 우측으로 이동하면서 분사작업이 완료하게 된다.In the present invention as described above, first, when the robot arm 4 reaches the left injection position of the inner surface of the panel on the inner surface of the panel 2 that has reached the position of the coating step, the phosphor 1 is discharged through the injection nozzle 3. ) Will begin to spray, and gradually move to the right to complete the spray.

상술한 과정이후에 다시 로봇암(4)이 상승하여 초기 위치에 도달하게 되면, 패널(2)의 하방에 위치한 트랜스듀셔(5)가 상하로 빠른 진동력으로 진동하기 시작하여 형광체 좌우로 확산되어 도 3 의(다)로 보인 바와 같이 고른 두께로 패널 내면에 도포되어 지는 것이다.After the above-described process, when the robot arm 4 is raised again to reach the initial position, the transducer 5 located below the panel 2 starts to vibrate with a fast vibration force up and down, and is diffused to the left and right of the phosphor. As shown in (c) of FIG. 3, it is applied to the inner surface of the panel with an even thickness.

그러므로 상술한 과정에 의한 본 고안은 형광체의 비중이나 점도등이 다소 뷸균일 하더라도 회전방식의 형광체 코팅방법보다 균일한 막두께의 형성이 가능한 것이다.Therefore, the present invention by the above-described process, even if the specific gravity or viscosity of the phosphor is somewhat uniform, it is possible to form a uniform film thickness than the phosphor coating method of the rotation method.

상술한 본 고안은 회전코팅시보다 형광체의 점도나 비중을 별도로 관리하지 않아도 되며, 또한 상하의 미세 진동으로 코팅되므로 균일한 막두께의 형성이 가능하며, 형광체가 밀려다니지 않아 기포의 발생우려가 저하되는 것이어서, 스크린 코팅의 품위를 향상시켜 화질개선에 기여할 수 있는 것이다.The present invention does not have to separately manage the viscosity or specific gravity of the phosphor than the rotation coating, and also because it is coated with a fine vibration of the upper and lower, it is possible to form a uniform film thickness, the possibility of the bubble is reduced because the phosphor is not pushed Therefore, it is possible to contribute to the improvement of image quality by improving the quality of the screen coating.
