Abstract
본 고안은 칼라브라운관의 판넬측면 노광장치에 관한 것으로, 판넬의 블랙코팅공정중에서 판넬의 전면만 노광이 되고, 판넬의 측면이 노광되지 못하여 후에 무반사 흑색도료가 판넬의 측면을 브러쉬로 닦아 주어야 하는 문제점을 해결하기 위하여 판넬의 전면이 노광이 되고 난 후에 광케이블이 설치된 판을 판넬의 내측에 상하로 이동이 가능하도록 설치함으로써 브러싱공정을 삭제하여 무반사 흑색도료의 제거작업을 용이하게 함과 아울러 흑색도료가 제거되고 난 후에도 판넬의 측면을 미려하게 하기 위한 것이다.The present invention relates to a panel side exposure apparatus of a color brown tube, in which the front side of the panel is exposed during the black coating process of the panel, and the side of the panel is not exposed, so that the anti-reflective black paint has to brush the side of the panel with a brush later. In order to solve the problem, after the front of the panel is exposed, the panel installed with the optical cable can be moved up and down inside the panel, eliminating the brushing process to facilitate the removal of the anti-reflective black paint and the black paint. This is to make the side of the panel beautiful even after it is removed.

본 고안은 칼라브라운관의 판넬측면 노광장치에 관한 것으로, 특히 판넬측면에 도포된 무반사 흑색도료를 제거하기 쉽도록 레지스트가 도포된 상태에서 판넬의 전면을 노광시키고 난 후에 판넬측면을 별도로 노광시키는 판넬측면노광장치에 관한 것이다.The present invention relates to an apparatus for exposing a panel side of a color brown tube, and in particular, a panel side for exposing the panel side separately after exposing the front side of the panel in a state where a resist is applied so as to easily remove the antireflective black paint applied to the panel side. It relates to an exposure apparatus.
브라운관 화면부의 3색 형광막을 형성시키는 공정으로서 스크린 공정은 블랙코팅공정과 스크린 공정으로 구분할 수 있는데 그중에서 블랙코팅공정은 형광체 스트라이프 상호간격의 사이에서 생기는 산란전자에 의한 불필요한 발광을 흡수하거나 외광을 흡수하여 밝고 어두운 부분의 명암비를 명확히 함으로써 선명한 화상을 얻게 하기 위해 무반사 흑색도료를 판넬내면에 도포하는 공정을 말한다.The screen process can be divided into black coating process and screen process. Among them, the black coating process absorbs unnecessary light emission by scattered electrons generated between the phosphor strips and absorbs external light. This is a process of applying an anti-reflective black paint to the inner surface of the panel to obtain a clear image by clarifying the contrast ratio of the bright and dark parts.
이와 같은 종래의 블랙코팅공정에 있어서 판넬내면에 도포 건조된 레지스트막을 소정의 형상으로 노광시키는 노광공정 중에는 판넬전면만 노광이 되고 판넬 측면이 노광되지 않으므로 레지스트현상고정 중에 판넬측면의 레지스트가 제거되어 판넬측면에 불필요한 무반사 흑색도료가 도포된다.In the conventional black coating process, during the exposure process in which the resist film coated on the inner surface of the panel is exposed to a predetermined shape, only the front surface of the panel is exposed and the panel side is not exposed. Therefore, the resist on the panel side is removed during fixing of the resist development. Unnecessary antireflective black paint is applied to the sides.
따라서 종래에는 상기한 바와 같이 불필요하게 도포된 흑색도료를 제거하기 위하여 전동브러쉬로 흑색도료를 제거하는 림 브러싱공정이 필요하였다.Therefore, in order to remove the black paint applied unnecessarily as described above, a rim brushing process for removing the black paint with an electric brush is required.
그러나 회전하는 전등브러쉬로 작업자가 흑색도료의 제거작업을 할 경우에 그 제거작업이 용이하지 않을 뿐만 아니라 세척액을 별도로 사용하여야 하고 브러쉬를 사용하므로 흑색도료가 제거가 된 후의 면의 상태도 좋지 않은 문제가 있었다.However, when the worker removes the black paint with the rotating light brush, the removal work is not easy and the cleaning condition must be used separately and the brush is used, so the state of the surface after the black paint is removed is not good. There was.
본 고안은 상기와 같은 제반 문제점을 해결하기 위하여 안출된 것으로, 상기 림 브러쉬공정을 없애고 노광공정과 레지스트 현상공정사이에 노광공정에서 노광이 되지 않은 판넬의 측면을 노광시키는 판넬측면 노광장치를 설치하여 판넬의 측면에 도포되는 불필요한 무반사 흑색도료의 제거를 용이하게 함을 목적으로 한다.The present invention was devised to solve the above problems, and by removing the rim brush process and installing a panel side exposure apparatus for exposing the side of the panel not exposed in the exposure process between the exposure process and the resist development process. It is intended to facilitate the removal of unnecessary antireflective black paint applied to the side of the panel.
상기와 같은 본 고안의 목적은 판넬이 상면에 안치된 안치대와, 상기 안치대의 내측으로 이동가능하도록 설치된 판과, 상기 판을 상하로 이동시킬 수 있도록 판의 하부에 설치되어 있는 로드를 구비한 실린더와, 상기 판의 상부에는 변둘레를 따라 설치된 발광수단으로 이루어진 판넬측면 노광장치를 제공함으로써 달성된다.An object of the present invention as described above is provided with a panel settled on the upper surface of the panel, a plate installed to be movable to the inside of the settable, and a rod provided on the lower portion of the plate to move the plate up and down It is achieved by providing a panel side exposure apparatus comprising a cylinder and light emitting means provided on an upper edge of the plate.
이하 본 고안의 바람직한 일실시예를 첨부도면에 의하여 상세히 설명한다.Hereinafter, a preferred embodiment of the present invention will be described in detail by the accompanying drawings.
제1도는 본 고안의 일실시예를 도시한 사시도이고, 제2도는 본 고안의 일실시예의 작동상태도이다.1 is a perspective view showing an embodiment of the present invention, Figure 2 is an operating state diagram of an embodiment of the present invention.
본 고안의 일실시예는 판넬(10)이 상면에 안치된 안치대(11)와, 상기 안치대(11)의 내측으로 이동가능하도록 설치된 판(20)과, 상기 판(20)을 상하로 이동시킬 수 있도록 상기 판(20)의 하부에 설치되어 있는 로드(21)를 구비한 실린더(22)와, 상기 판(20)의 상부에 변둘레를 따라 설치된 발광수단으로 이루어진 것이다.One embodiment of the present invention, the panel 10 is settled on the upper surface of the set 11, the plate 20 is installed to be movable inside of the set 11, and the plate 20 up and down It consists of a cylinder 22 having a rod 21 installed on the lower portion of the plate 20 so as to be movable, and light emitting means provided along the perimeter of the plate 20.
상기 발광수단은 광케이블(30)로 되어 있다.The light emitting means is an optical cable 30.
전면 노광이 완료된 판넬(10)이 이송되어 안치대(11)의 상면에 안치되면 실린더(22)의 로드(21)가 전진하여 상기판(20)을 안치대(11)의 내측으로 이송시킨다. 이상태에서 상기 광케이블(30)에 의하여 판넬의 내측면이 노광이 된다.When the panel 10 having been subjected to the entire surface exposure is transferred to be placed on the upper surface of the set 11, the rod 21 of the cylinder 22 is advanced to transfer the plate 20 to the inside of the set 11. In this state, the inner surface of the panel is exposed by the optical cable 30.
제3도는 본 고안의 또 다른 실시예를 도시한 종단면도인데, 광케이블(30)로부터 나온 빛이 판넬 측면으로 집중되도록 광케이블(30)의 상부에 반사갓(31)을 설치하여서 된 것이다.3 is a longitudinal cross-sectional view showing another embodiment of the present invention, by installing a reflection shade 31 on the upper portion of the optical cable 30 so that the light from the optical cable 30 is concentrated to the side of the panel.
상술한 바와 같은 본 고안에 따르면 판넬측면에 도포된 레지스트가 노광이 되므로 레지스트 현상공정에서 레지스트가 제거되지 않은 상태로 무반사 흑색도료가 도포되어 레지스트 분해공정에서 손쉽게 무반사 흑색도료가 제거될 수 있다.According to the present invention as described above, since the resist coated on the panel side is exposed, the antireflective black paint is applied without removing the resist in the resist developing process, so that the antireflective black paint can be easily removed in the resist decomposition process.
따라서 본 고안에 의하면 림브러싱공정이 삭제되어 무반사 흑색도료의 제거작업이 용이함과 아울러 흑색도료가 제거되고 난 후에도 판넬의 면이 미려해지는 효과가 있다.Therefore, according to the present invention, the rim brushing process is eliminated to facilitate the removal of the anti-reflective black paint, and the panel surface is beautiful even after the black paint is removed.
