본 고안은 브라운관의 판넬(panel)내면에 도포된 형광막을 검사하는 검사대용 조명장치에 관한 것으로, 더 상세히는 시각적으로 용이하게 검사할 수 있도록 간접조명을 적용한 간접 조명장치에 관한 것이다.The present invention relates to a lighting device for the inspection table for inspecting the fluorescent film applied to the inner surface of the panel (panel) of the CRT, and more particularly to an indirect lighting device to which indirect lighting is applied to be easily visually inspected.
통상의 브라운관 제조공정에 있어서 브라운관의 판넬 내면에 형광막을 도포한 후 그에 대한 검사과정을 거치게된다. 이 검사는 주로 판넬 내면과 그둘레부분에 형광막이 고르게 도포되었는지 또는 이물질이 묻어 있는지를 조명아래에서 사람의 시각으로 행하는 브라운관의 외관검사이다.In a typical CRT manufacturing process, a fluorescent film is applied to an inner surface of a CRT panel and then inspected. This test is mainly a visual inspection of the CRT, which is carried out by human vision under the illumination of whether the fluorescent film is evenly applied to the inside of the panel and its periphery.
그런데, 종래에는 제1도에 도시한 바와같이, 이러한 브라운관(3)의 검사를 직접조명되는 조명장치(2)아래에서 행하였다. 다시말해서, 브라운관(3)의 판넬 내면에 형광막이 도포된 후 도시하지 않은 행거(hanger)등의 이송수단에 의해 검사대(1)에 이르러 이송되는 중 또는 일시 정지상태에서 검사대(1)의 상부에 설치된 조명장치(2)의 광에 의해 육안검사를 행하였다.By the way, conventionally, as shown in FIG. 1, the inspection of the CRT 3 was performed under the illuminating device 2 directly illuminated. In other words, after the fluorescent film is applied to the inner surface of the panel 3 of the CRT 3, the fluorescent film is applied to the upper side of the inspection table 1 while being conveyed to the inspection table 1 by a conveyer such as a hanger or the like not shown. Visual inspection was performed by the light of the installed lighting device 2.
그러나, 이러한 종래의 조명장치는 직접조명이기 때문에 브라운관의 외관검사시에 광이 고르게 분포되지 않고 일부에 집중되기도하며, 필요시 조명장치를 2조이상 설치하여야 할 경우에는 조명장치간의 이격된 거리에 의하여 브라운관의 판넬표면을 상대적으로 흐르게 비추는 부분이 생긴다. 그러므로 검사의 정확성을 기하지 못하는 제품의 불량을 초래하는 문제점이 있었다.However, since the conventional lighting device is a direct light, the light is not evenly distributed during the inspection of the CRT and may be concentrated in a part, and when two or more sets of lighting devices are required, if necessary, at a spaced distance between the lighting devices. This creates a part that reflects the panel surface of the CRT relatively. Therefore, there was a problem that causes the failure of the product does not give the accuracy of the inspection.
본 고안의 목적은 상술한 문제점을 해결하기 위한 것으로, 조명장치의 빛을 브라운관에 고르게 비추도록하여 검사자가 검사하는데 있어서 최적의 조명상태를 확보하는데 있다.An object of the present invention is to solve the above problems, to ensure that the light of the lighting device evenly illuminates the CRT to ensure the optimal lighting state for the inspector.
이와같은 목적을 달성하기 위하여 본 고안은 조명장치의 광이 난반사를 일으킬 수 있도록 조명장치와 브라운관 사이에 반투명판넬을 설치하는 간접조명 장치를 제공한다.In order to achieve the above object, the present invention provides an indirect lighting device that installs a translucent panel between the lighting device and the CRT so that light of the lighting device causes diffuse reflection.
이하, 첨부된 도면을 참조하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제2도 및 3도에 도시한 바와같이, 본 고안은 검사대(1)의 내부 상부에 조명등(2)을 설치한 것에 있어서, 조명등(2)하방에 반투명판(6)을 설치하고, 이를 위하여 2개의 고정편(4)을 검사대 내부 양측벽에 고정한 것이다.As shown in FIG. 2 and FIG. 3, the present invention is to install a lamp (2) in the upper portion of the interior of the inspection table (1), to install a translucent plate (6) below the lamp (2), for this purpose Two fixing pieces 4 are fixed to both side walls inside the test table.
고정대(4)는 바람직하기로는 합성수지재의 "ㄴ"자형 부재로서, 다수의 고정공(4')을 형성하여 고정볼트(5)에 의해 검사대(1)의 내부 양측벽에 각각 고정된다.Fixing table 4 is preferably a "b" shaped member of a synthetic resin material, and forms a plurality of fixing holes (4 ') are fixed to the inner side walls of the test table 1 by fixing bolts 5, respectively.
반투명판넬(6)은 바람직하기로는 아크릴판으로 하여 고정대(4)의 수평부에 걸칠 수 있도록 길이를 정하고, 브라운관(3)에 간접광을 조사하기에 충분한 너비로 선정하거나, 다수의 반투명판넬편을 마련하여 연결한 너비가 소정의 크기를 갖도록 하여도 좋다. 또한, 반투명판넬(6)은 되도록 두께가 얇고 휘어지지 않는 것이 좋으며, 조명장치(2)와 대응하는 면을 거칠게 하여 조명빛이 난반사를 일으키도록 하면 더욱 효과적이다.The translucent panel 6 is preferably an acrylic plate, the length of which is fixed to the horizontal portion of the fixing stand 4, and the width of the translucent panel is selected to be sufficient to irradiate the CRT 3 with indirect light, or a plurality of translucent panel pieces It may be provided so that the connection width has a predetermined size. In addition, the semi-transparent panel 6 is preferably as thin as possible and not bent, and it is more effective to roughen the surface corresponding to the lighting device 2 so that the illumination light causes diffuse reflection.
이와 같은 구성된 본 고안의 설치시에는, 먼저 검사대(1)에 설치된 조명장치(2)의 아래쪽에 위치되게 검사대(1)의 양측 벽면에 수평을 맞추어 고정대(4)의 고정공(4')을 통하여 고정볼트(5)로서 고정한다.In the installation of the present invention configured as described above, the fixing holes 4 'of the fixing stand 4 are horizontally aligned with both side walls of the inspection stand 1 so as to be positioned below the lighting device 2 installed on the inspection stand 1. Fix it as a fixing bolt (5).
이와같이 고정된 고정대(4)에 반투명판넬(6)의 양단을 걸쳐서 올려놓게 되며, 반투명판넬(6)은 고정대(4)에서 전후로 이동이 가능하며 사용중에 먼지등의 이물질이 묻게되면 빼내어 청소를 할 수 있다. 또한, 필요시 반투명판넬(6)을 여러개 마련하여 고정대(4)상에 겹쳐 사용할 수도 있다.The translucent panel 6 is placed on both ends of the translucent panel 6, and the translucent panel 6 can be moved back and forth from the fixture 4, and when foreign matter such as dust gets in use, the dust can be removed and cleaned. Can be. In addition, if necessary, a plurality of translucent panels 6 may be provided and used on the fixing table 4.
따라서, 브라운관(3)의 판넬부에 대한 외관검사시에, 조명장치(2)의 빛이 반투명판넬(6)에서 1차로 난반사하여 통과된 간접조명이 브라운관(3)의 판넬부에 고르게 비추어지게 됨으로써 형광막의 도포상태나 이물질의 부착여부를 좀더 명확히 판별할 수 있게되며, 검사자의 시력보호와 피로감소의 효과를 주게된다.Therefore, at the time of visual inspection of the panel portion of the CRT 3, the indirect illumination passed through the first diffuse reflection of the light of the lighting device 2 in the semi-transparent panel 6 is evenly reflected on the panel portion of the CRT 3. As a result, the coating state of the fluorescent film and the adhesion of foreign matters can be more clearly distinguished, and the vision of the inspector and the fatigue reduction effect are provided.
