본 고안은 알루미늄(Al) 증착장치, 더욱 상세히는 판넬내면에 알루미늄을 증착하기 위한 알루미늄증착장치에 관한 것이다.The present invention relates to an aluminum (Al) deposition apparatus, and more particularly to an aluminum deposition apparatus for depositing aluminum on the inner surface of the panel.
브라운관의 제작시 판넬(Panel)의 내면에는 형광면의 휘도증가 및 형광면 전위의 강하방지등의 목적으로 알루미늄막을 증착하게 된다.In manufacturing the CRT, an aluminum film is deposited on the inner surface of the panel for the purpose of increasing the luminance of the fluorescent surface and preventing the drop of the fluorescent surface potential.
상술한 목적으로 사용되는 종래의 알루미늄(Al) 증착장치는 통상 더미콘(Dummy Cone)이라고 칭하는 박스형의 부재내에서 급. 배기를 실시하면서 반복적으로 수행한다.Conventional aluminum (Al) deposition apparatus used for the above-mentioned purposes is generally supplied in a box-shaped member called a dummy cone. It is performed repeatedly while exhausting.
증착은 배기후 고진공상태에서, 히터에 의하여 알루미늄본을 기화시켜 실시하게 되며 증착후에는 급기하는 과정을 거쳐야 한다. 따라서 더미콘내의 환경은 매우 열악한 고온·저온의 반복상태이다.Deposition is carried out by evaporating the aluminum bone by a heater in a high vacuum state after exhausting, and must be supplied with air after deposition. Therefore, the environment in the dummy cone is a very bad high temperature and low temperature repetition state.
이러한 종래의 알루미늄(Al)증착장치에 있어서는 증착후에 급기를 할때, 급기되는 공기는 거의 상온이고 히터의 증착후의 순간온도는 거의 섭씨 150 내지 1600도에 이르게 된다.In this conventional aluminum (Al) deposition apparatus, when air is supplied after deposition, the air to be supplied is almost room temperature, and the instantaneous temperature after deposition of the heater is almost 150 to 1600 degrees Celsius.
따라서 상온의 공기는 히터에 직접 부딪히게 되며 히터의 급격한 냉각경화와 재가열등으로 인한 균일과 절단 등이 발생하는 등의 급격한 환경변화로 인한 히터수명의 단축과 알루미늄증착상태가 저하되어 빈번한 수리와 교체를 요하기 때문에 원가와 생산성 및 제품품질면에서 바람직하지 못한 문제점이 있다.Therefore, the air at room temperature hits the heater directly, and due to the rapid environmental change such as the rapid cooling hardening and reheating of the heater, the shortening of the heater life due to the rapid change in the environment and the deterioration of the aluminum deposition state, the frequent repair and replacement There is an undesirable problem in terms of cost, productivity and product quality.
본 고안은 이러한 종래의 문제점을 해결하기 위하여 안출된 것으로서 개선된 알루미늄(Al)증착장치를 제공함으로서 상대적으로 저온의 외기가 직접 히터에 접하지 않게 하는 것을 목적으로 한다.The object of the present invention is to provide an improved aluminum (Al) deposition apparatus devised to solve such a conventional problem, so that relatively low temperature outside air does not directly contact the heater.
이러한 목적을 달성하기 위하여 본고안에 의한 알루미늄(Al)증착장치는 흡배기구에 유입되는 공기의 흐름을 굴절시켜 과도적인 온도조절시간을 부여하게 하는 필터를 가지는 것을 특징으로 한다.In order to achieve this purpose, the aluminum (Al) deposition apparatus according to the present invention is characterized in that it has a filter that gives a transient temperature control time by refracting the flow of air flowing into the intake and exhaust.
이하 첨부된 도면을 참조로 하여 본고안의 바람직한 하나의 실시례를 상세히 설명한다. 제1도는 본고안의 알루미늄(Al)증착장치의 개략적인 측단면도, 제2도는 본고안의 알루미늄(Al)증착장치에 사용되는 흡배기구필터의 일실시례를 도시한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a schematic side cross-sectional view of the aluminum (Al) deposition apparatus of the present invention, and FIG. 2 shows one embodiment of the intake and exhaust filter used for the aluminum (Al) deposition apparatus of the present invention.
팩킹(5)등으로 밀봉, 안착되는 판넬(4)은 더미콘(1)상방에 놓여지며 더미콘(1)의 측방에는 배기관(2)과 급기관(3)이 일체로 연결되는 급배기구(6)가 마련된다.The panel 4 sealed and seated by the packing 5 is placed above the dummy cone 1, and an exhaust pipe 2 and an air supply pipe 3 are integrally connected to the side of the dummy cone 1. 6) is provided.
종래의 기술에서는 상술한 단일의 급배기구(6)로 순차적으로 배기. 흡기가 이루어지고 이 과정에서 더미콘(1)내의 장치(히터(7))가 상온의 급기와 직접 접하게 된다.In the prior art, the exhaust gas is sequentially exhausted by the single supply / exhaust mechanism 6 described above. Intake is made, and in this process, the device (heater 7) in the dummy cone 1 is in direct contact with the air supply at room temperature.
본 고안의 알루미늄(Al)증착장치에서는 급배기구(6)상에 일차적인 공기흐름을 제어할 수 있는 급배기구필터(10)가 부착된다.In the aluminum (Al) deposition apparatus of the present invention, the air supply and exhaust pipe filter 10 that can control the primary air flow on the air supply and exhaust pipe (6) is attached.
본 고안의 알루미늄(Al)증착장치에 사용되는 일실시례의 급배기구필터(10)는 제2도에 도시된 바와같은 개략『ㄷ』형상의 판상금속부재로서 급배기구(6)에 부착되어 일차적인 공기의 흐름을 변경시킨다. 즉, 상대적으로 저온인 급기 공기를 히터에 직접 부딪히지 않고 일단 급배기구필터(10)에 부딪히게 한다.The air supply / exhaust filter 10 of one embodiment used in the aluminum (Al) deposition apparatus of the present invention is a plate-shaped metal member having a roughly '?' Shape as shown in FIG. Changes the flow of air. In other words, the relatively low temperature of the supply air does not directly hit the heater once hits the air supply and exhaust filter (10).
급배기구필터(10)는 도시한 형상이외의 다양한 형상의 것이 될 수 있음은 물론이다.The supply and exhaust vent filter 10 may be of various shapes other than the shape shown.
이상과 같은 알루미늄(Al)증착장치는 급기시에 상대적으로 저온인 공기가 직접 더미콘(1)내의 히터(7)등의 장치와 부딪히지 않고 일차적으로 급배기구필터(10)에 부딪힌 후에 와류가 다시 더미콘(1)의 저면 및 벽면을 따라서 급기되기 때문에 종래의 알루미늄(Al) 증착장치에서와 같이 급격한 온도변화를 장치물에 유발시키지 않기 때문에 수명의 연장, 품질의 향상등의 효과를 가진다.As described above, in the aluminum (Al) deposition apparatus, the vortex flows again after the relatively low-temperature air hits the air supply and exhaust filter 10 without first colliding with a device such as a heater 7 in the dummy cone 1. Since air is supplied along the bottom surface and the wall surface of the dummy cone 1, it does not cause a sudden temperature change in the apparatus as in the conventional aluminum (Al) deposition apparatus, and thus has an effect of extending the life and improving the quality.
