본 고안은 평판(平板) 압착(壓着)장치에 대한 것으로, 액정표시소자(Liquid Crystal Display; LCD)등의 평판소재의 압착에 적합한 압착장치에 관한 것이다.The present invention relates to a flat plate pressing device, and a pressing device suitable for pressing a flat plate material such as a liquid crystal display (LCD).

평판소재를 접착제등에 의해 상호 접합시키기 위해서는 접합될 평판소재를 균일한 압력으로 압착시켜 주지않으면 안된다.In order to bond the plate materials to each other with an adhesive or the like, the plate materials to be joined must be pressed at a uniform pressure.

예를 들어 LCD제조공정을 살펴보면, 두 원판에 각각 표면과 배면 전극 패턴등을 복수로 형성한뒤 봉합재(sealant)로 접합한뒤 이를 각 단위소자로 절단하여 액정을 주입 및 밀봉함으로써 LCD를 제조하고 있다. 따라서 이 봉합에 의해 표면전극과 배면전극 간의 거리, 즉 셀갭(cell gap)이 결정되므로, 균일하고 정확한 셀갭을 얻기 위해서는 봉합과정중에 있어 원판을 균일한 압력으로 압착시켜 주지 않으면 안된다.For example, in the LCD manufacturing process, LCDs are manufactured by forming a plurality of surface and back electrode patterns on each of two original plates, bonding them with a sealant, cutting them into unit devices, and injecting and sealing liquid crystals. Doing. Therefore, since the distance between the surface electrode and the back electrode, that is, the cell gap, is determined by the sealing, the original plate must be pressed at a uniform pressure during the sealing process in order to obtain a uniform and accurate cell gap.

제1도에 이러한 LCD의 봉합에 사용되는 핫 프레스(hot press)를 도시하였다. 이것은 각각 하이터가 내장되어 액튜에이터(actuator : 21)로 구동되는 두 가열판(hot plate : 20)으로 프레스를 구성하여 그 사이에 접합될 복수의 LCD원판(22)들을 가열 및 가압하도록 된 구성이다. 가열판(20)은 과도한 온도상승을 방지하기위해 통상 알루미늄 재질로 구성되어 프레스의 다른 부분에 전열에 의한 영향을 주지않도록 각각 방열핀(fin)이형성된 복수의 알루미늄제 지지핀(support pin ; 23)에 지지된다.1 shows the hot press used to seal such LCDs. This is configured to heat and press the plurality of LCD discs 22 to be joined therebetween by forming a press with two hot plates 20 each having a built-in heater and driven by an actuator 21. The heating plate 20 is formed of a plurality of aluminum support pins 23, which are usually made of aluminum to prevent excessive temperature rise, and each having heat radiating fins formed thereon so as not to be affected by heat transfer to other parts of the press. Supported.

이에 따라 장치의 구성이 매우 복잡해질 뿐아니라, 취약한 알루미늄 재질로 된 가열판(20)과 지지핀(23)이변형되어 가열판(20)이 평활도를 유지하기 어렵게 되므로 압력이 국부적으로 불균형되어 균일한 셀갭은 얻을 수 없는 문제점이 있었다. 또한 액튜에이터(21)로 구동되므로 별도의 압력공급 장치를 구비하여야 하며, 가열판(20)이 유리제의 LCD 원판(22)에 충돌하여 이를 손상시키지 않도록 하기 위해서는 액튜에이터(21)의 작동속도를 완만하게 하여야 한다. 그럼에도 불구하고 압착력의 부적절에 의해 LCD원판(22)을 파손시키는 문제점이 발생하였다.As a result, the configuration of the device becomes very complicated, and the heating plate 20 and the support pins 23 made of a weak aluminum material are deformed, so that the heating plate 20 is difficult to maintain smoothness. There was an issue that could not be obtained. In addition, since it is driven by the actuator 21, a separate pressure supply device must be provided, and in order to prevent the heating plate 20 from colliding with the glass LCD plate 22 and damaging it, the operating speed of the actuator 21 must be made gentle. do. Nevertheless, there is a problem of damaging the LCD disc 22 due to inadequate pressing force.

본 고안은 이러한 종래의 문제점을 감안하여, 장치의 구성이 매우 간단하면서도 균일한 가압이 가능하고 가압되는 평판소재 손상시키지 않는 평판의 압착장치를 제공하는 것을 목적으로 한다.The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a compaction apparatus of a flat plate which is very simple and uniform in pressurization and which does not damage the pressurized flat plate material.

이러한 목적을 달성하기 위해 본 고안에 의한 평판 압착장치는 하나 또는 복수로 적층된 평판을 압착하는 장치에 있어서, 평판을 적재하는 진공실을 구비하는 기판과, 진공실을 덮는 탄성막을 구비하는 커버를 구비하여, 진공실을 배기하여 진공상태로 함으로써 탄성막상에 걸리는 대기압에 의해 평판을 압착시키는 것을 특징으로한다.In order to achieve the above object, the flat plate pressing device according to the present invention is a device for compressing one or a plurality of stacked flat plates, comprising: a substrate having a vacuum chamber for loading the flat plate and a cover having an elastic film covering the vacuum chamber. The vacuum chamber is evacuated to a vacuum state, and the plate is pressed by atmospheric pressure applied to the elastic membrane.

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

제2도에서, 본 고안에 의한 압착장치는 평판소재가 적층되어 지지되는 기판(1)과, 이 기판(1)과, 이 기판(1)에 그 일단이 힌지(hinge)결합되며 탄성막(7)을 구비하는 커버(cover; 2)로 구성된다.In FIG. 2, the crimping apparatus according to the present invention has a substrate 1 on which a flat plate material is stacked and supported, and one end thereof is hinged to the substrate 1 and the substrate 1, and an elastic membrane ( And a cover 2 having 7).

기판(1)에는 상방으로 측벽(3)이 연장되어 압착될 평판이 복수로 적층되는 진공실(4)이 형성되는데, 진공실(4)의 하부에는 배기구멍(5)이 도시되지 않은 부압원(負壓源)에 연결된다. 한편이 진공실(4)은 필요에 따라 구획벽(6)으로 분리되는데 도시된 실시예에서는 평판소재를 2열로 적재하도록 2부분으로 구획되어 있다.The substrate 1 is formed with a vacuum chamber 4 in which a plurality of flat plates to be squeezed are formed by extending the side wall 3 upwardly. A negative pressure source (not shown) in which the exhaust hole 5 is not shown is provided in the lower part of the vacuum chamber 4. Connected to the source. On the other hand, the vacuum chamber 4 is separated into partition walls 6 as necessary. In the illustrated embodiment, the vacuum chamber 4 is divided into two parts so that the plate material is loaded in two rows.

한편 커버(2)는 탄성막(7)의 설치를 위해 바람직하기로는 상판(8)과 하판(9)으로 형성되어, 그 사이에 탄성막(7)을 끼운채 볼트(11)로 상호결합된다. 탄성막(7)의 소재는 예를 들러 실리콘 고무등 고탄성 내열(耐熱)재질인 것이 바람직하다.On the other hand, the cover 2 is preferably formed by the upper plate 8 and the lower plate 9 for installation of the elastic membrane 7, and is mutually coupled with the bolt 11 with the elastic membrane 7 sandwiched therebetween. . It is preferable that the raw material of the elastic membrane 7 is high elastic heat-resistant material, such as silicone rubber, for example.

커버(2)와 기판(1)을 결합상태로 로킹(locking)시키기 위해 도시된 실시예에서는 커버(2)상에 각각 레버(lever; 13)에 의해 회전 가능한 복수의 반달록(crescentlcok; 12)을 설치하고, 기판(1)의 대응위치에 로킹흠(14a)을 구비하는 로킹블록(locking block; 14)을 설치한다.In the illustrated embodiment for locking the cover 2 and the substrate 1 in an engaged state, a plurality of crescentlcoks 12 rotatable by levers 13 respectively on the cover 2 are provided. And a locking block 14 having a locking flaw 14a at a corresponding position of the substrate 1.

나머지 부호 10은 커버(2)와 기판(1)간의 밀봉을 위한 가스켓(gasket), 15와 16은 각각 커버(2)와 기판(1)의 힌지결합을 위한 브라켓(bracket)들이다.The remaining 10 is a gasket for sealing between the cover 2 and the substrate 1, and 15 and 16 are brackets for hinge coupling of the cover 2 and the substrate 1, respectively.

이와 같은 본 고안 압착장치의 작동을 제3도를 참조하여 설명한다. 먼저 기판(1)의 측벽(3)내의 진공실(4)에 압착될 복수의 평판(P)을 적층시킨다. 다음 커버(2)를 덮고 각 레버(13)룰 돌려 반달록(12)이 기판(1)의로킹블록(14)의 로킹 홈(14a)에 걸려 커버(2)를 기판(1)에 결합고정시킨다. 다음 배기구멍(5)을 통해 진공실(4)내를 진공상태로 만들면 커버(2)의 탄성막(7)이 이진공부압에 의해 평판(P)의 상면에 밀착된다. 탄성막(7)의 하면은 진공이고 상면에는 균일한 대기압이 걸리고 있으므로 평판(P)의 상면에는 대기압, 즉 약 10m의 수주(水柱)에 해당하는 1, 013kg/cm2의 압력이 걸리게 된다. 이 대기압은 탄성막(7)의 상면에 균일하게 걸리고 있는 상태이므로 적층된 평판(P)은 균일한 압력으로 압착된다. 또한 탄성막(7)은 고탄성의 재질이므로 압착되는 평판(P)을 손상시키거나 과도한 압력을 가하는 일이 없다.The operation of the present invention crimping device will be described with reference to FIG. First, a plurality of flat plates P to be compressed are stacked on the vacuum chamber 4 in the side wall 3 of the substrate 1. Then cover the cover (2) and turn the lever (13) to turn the half moon 12 is caught in the locking groove (14a) of the locking block 14 of the substrate 1 to secure the cover 2 to the substrate 1 Let's do it. Next, when the inside of the vacuum chamber 4 is made into a vacuum state through the exhaust hole 5, the elastic membrane 7 of the cover 2 is brought into close contact with the upper surface of the flat plate P by the vacuum vacuum pressure. Since the lower surface of the elastic membrane 7 is vacuum and the upper surface is subjected to a uniform atmospheric pressure, the upper surface of the flat plate P is subjected to atmospheric pressure, that is, a pressure of 1,013 kg / cm 2 corresponding to a water column of about 10 m. Since the atmospheric pressure is uniformly applied to the upper surface of the elastic membrane 7, the laminated flat plates P are pressed at a uniform pressure. In addition, since the elastic film 7 is a material of high elasticity, the elastic plate 7 is not damaged or exerted excessive pressure.
