Abstract

본 발명은 브라운관 제조에 쓰이는 로광대의 셋팅정도를 확인하는 방법에 관한 것으로, 특히 검사용 기준판넬을 제작하고, 이 기준판넬을 이용하여 로광대의 셋팅정도를 확인하는 방법이다.The present invention relates to a method for confirming the setting degree of the furnace lamp used in the manufacture of CRT, and in particular, to produce a reference panel for inspection, and a method of confirming the setting degree of the furnace lamp using this reference panel.

종래에는 로광대의 셋팅이 정확한 지를 알기 위해서는 브라운관 튜브를 완성하여 검사할 수 밖에 없으므로 튜브 작동의 복합적인 요인에서 로광대 셋팅정도만을 구분하여 확인하기 어렵고 완성된 튜브들이 불량처리되는 문제점이 있었다.Conventionally, in order to know whether the setting of the furnace stand is accurate, the CRT tube cannot be inspected by completing the tube.

본 발명은 브라운관 제조에 쓰이는 로광대의 셋팅 정도를 확인하는 방법에 관한 것으로, 특히 검사용 기준 판넬을 제작하고, 이 기준판넬을 이용하여 로광대의 셋팅정도를 확인하는 방법에 관한 것이다.The present invention relates to a method for confirming the setting degree of the furnace lamp used in the manufacture of CRT, and more particularly, to a method for manufacturing a reference panel for inspection and to determine the setting degree of the furnace lamp using this reference panel.

로광대는 수은램프를 광원으로 하여 전자빔의 궤적에 해당하는 광선의 경로를 얻기위해 보정렌즈, 보정필터, 셔터 등을 구비하고 섀도우 마스크를 장착하여 패널내면을 로광하는 장치이다.The furnace lamp is a device that emits the inner surface of the panel by using a mercury lamp as a light source and having a correction lens, a correction filter, a shutter, etc., and a shadow mask to obtain a path of light rays corresponding to the trajectory of the electron beam.

종래에는 로광대의 셋팅 정도를 확인하기 위해서는 브라운관 튜브를 완성하여 형광체에 전자빔을 조사해 보아야만 로광대가 정확하게 셋팅되어 있는지 여부를 확인할 수 있었다.Conventionally, in order to check the setting degree of the furnace band, it is necessary to complete the CRT tube and irradiate the electron beam to the phosphor to confirm whether the furnace band is correctly set.

그러나 이러한 종래의 방법은 완성된 튜브가 로광의 정밀도 이외에 여러 복합적인 요소들로 작용하므로 로광대의 셋팅정도만을 구분하여 확인하기가 어렵고 로광이 부정확할 경우 완성된 튜브들이 불량처리되는 문제점이 있었다.However, this conventional method is difficult to identify only the setting degree of the furnace as the finished tube acts as a complex element in addition to the precision of the furnace, there is a problem that the finished tube is poorly processed if the furnace is inaccurate.

이에 본 발명은 검사용 기준 판넬을 제작하고 이 기준판넬을 이용하여 로광대의 셋팅정도를 확인할 수 있는 로광대 셋팅정도 확인 방법을 제공하는 것을 목적으로 한다.Accordingly, an object of the present invention is to provide a method for confirming the setting of the light guide bar to check the setting degree of the light guide bar by manufacturing a reference panel for inspection and using the reference panel.

위와 같은 목적을 달성하기 위하여 본 발명은 판넬에 포토레지스터(Photoresister)를 도포하고, 실온에서 서냉한후, 로광하고 현상·건조하고, 블랙스트라이프 재료를 도포·건조하고, 포토레지스터를 분해하여 블랙스트라이프를 현상하고, 적·녹·청색중 한가지 형광체를 도포·건조하고, 섀도우 마스크가 없는 상태에서 로광하여 기준판넬을 제작하고, 기준판넬에 섀도우 마스크를 장착하여 로광대에 안치시키고 숍 마스크로스코프(Shop Microscope)로 패널 외면에서 보아 광원이 블랙스트라이프 사이의 중심점에 오는지를 관찰하는 과정으로 이루어진다.In order to achieve the above object, the present invention is applied to the panel by a photoresist (Photoresister), and then slowly cooled at room temperature, and then blasted and developed and dried, the black stripe material is applied and dried, the photoresist is decomposed to black stripe Develop, apply and dry one of red, green and blue phosphors, and make a reference panel by emitting light in the absence of a shadow mask, and attach a shadow mask to the reference panel and place it on a lamp stand and store a shop mask scope ( Shop Microscope is the process of observing the light source coming from the center of the black stripe from the outside of the panel.

따라서 본 발명의 청구항은 제1항의 제작된 기준판넬과, 제2항의 기준판넬을 이용한 로광대 셋팅정도 확인 방법으로 이루어진다.Therefore, the claim of the present invention consists of a reference panel manufactured according to claim 1, and a setting method of the furnace band setting degree using the reference panel of claim 2.

이하 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 판넬에 블랙스트라이프를 형성시키고 적·녹·청색중 한가지 형광체를 도포한후 섀도우 마스크없이 로광하여 기준판넬을 제작하고, 제작된 기준판넬을 섀도우 마스크와 함께 로광대에 안치시켜 광원이 블랙스트라이프 사이의 중심점에 오는지를 숍 마이크로스코프로 확인하는 과정으로 이루어진다.The present invention forms a black stripe on the panel and applies one of red, green, and blue phosphors, and then emits the light without a shadow mask to produce a reference panel, and places the manufactured reference panel together with a shadow mask on a light table so that the light source is black. This is done by checking with the shop microscope whether it is at the center point between the stripes.

판넬에 블랙스트라이프를 형성시키기 위해 먼저 감광성 수지막인 포토레지스터를 도포하고, 실온에서 서냉건조시킨다. 브라운관 제작시에는 히터로 건조시키지만 본 발명에서 서냉 건조시키는 이유는 블랙스트라이프의 크기를 크게하여 숍 마이크로스코프로 관찰할 때 잘 식별되도록 하기 위한 것이다. 실제로 실온에서 포토레지스터를 서냉 건조한 후 블랙스트라이프를 형성시키면 폭이 항상 제작된 판넬보다 10~20㎛증대한다는 것이 확인되었다. 다시 서냉된 포토레지스터막을 로광하고 현상·건조한후, 포토레지스터를 분해하여 블랙스트라이프를 형성시킨다.In order to form a black stripe on the panel, a photoresist, which is a photosensitive resin film, is first applied and then slowly cooled at room temperature. The CRT is dried with a heater, but the slow cooling drying in the present invention is to increase the size of the black stripe so as to be well identified when observed with a shop microscope. In fact, when the black resist was formed after the photoresist was slowly cooled at room temperature, it was confirmed that the width always increased by 10 to 20 μm over the manufactured panel. After the slow cooled photoresist film is lowered, developed and dried, the photoresist is decomposed to form a black stripe.

이 상태의 판넬에 적·녹·청색중 한가지 형광체를 도포·건조하고 제품제작과 달리 섀도우 마스크가 없는 상태에서 로광하여 기준 패널을 완성시킨다.The panel in this state is coated with one of red, green, and blue phosphors, and dried. The product is then processed in the absence of a shadow mask to produce a reference panel unlike a product.

기준 판넬이 완성되면 섀도우 마스크를 장착하여 로광대를 안치시키고 제1도에 도시된 바와 같이 숍 마이크로스코프(40)로 판넬글라스(11)외면에서 보아 광원(30)이 섀도우 마스크(20)의 구멍으로 형광체(13)에 비추어져 양쪽 블랙스트라이프(12)사이에 정확히 위치하는지를 숍 마이크로스코프(40)의 중심선과 일치시켜보아 로광대의 셋팅정도를 확인한다.When the reference panel is completed, the shadow mask is mounted to set the furnace band, and as shown in FIG. 1, the light source 30 is viewed from the outside of the panel glass 11 with the shop microscope 40 so that the hole of the shadow mask 20 is visible. By matching the center line of the shop microscope 40 to see if it is accurately positioned between the two black stripe 12, which is illuminated by the phosphor 13, the setting degree of the furnace band is checked.

이와 같이 본 발명은 기준판넬을 이용하여 로광대의 셋팅 정도를 확인하므로 로광대의 셋팅 정도를 정확히 알 수 있고 로광대의 부적당한 셋팅에 의한 제품의 불량을 막고 품질을 향상시키는 효과가 있다.As described above, the present invention checks the degree of setting of the furnace lamp using a reference panel, so that the degree of setting of the furnace lamp can be accurately known, and there is an effect of preventing product defects and improving quality due to improper setting of the furnace lamp.
