본 고안은 액정표시소자(LCD)의 제조에 관한 것으로, 더 상세하는 LCD와 이 LCD구동용 회로모듈(module)을 조립하는 장치에 관한 것이다.The present invention relates to the manufacture of a liquid crystal display (LCD), and more particularly to an LCD and a device for assembling a circuit module for driving the LCD.
저(底)구동전압 및 저 소비전력으로 전자기기의 경박단소(輕薄短小)화에 부응하고 있는 LCD는 점차 그 사용영역이 확대되고 있다. LCD는 일반적으로 그 구동회로가 형성된 회로모듈상에 일체로 결합되어 LCD조립체가 되는데, 양자의 기계적 조립에는 후술하는 구성의 홀더(holder)가 사용되고, 양자의 전기적 접속에는 소위 제브라 커넥터(Zebra connector)가 사용된다. 제브라 커넥터는 도전성 고무등으로 된 다수의 도전셀(導電cell)이 상호 절연된 상태로 횡방향으로 배열된 유연한 띠(band)형태의 전기적 접속부품으로서 다수 전극간의접속에 유용하게 사용된다.With the low driving voltage and the low power consumption, LCDs, which are responding to the light and small size of electronic devices, are increasingly being used. LCDs are generally integrated into a circuit module on which a drive circuit is formed to form an LCD assembly. A holder of a configuration described below is used for both mechanical assembly, and a so-called zebra connector for electrical connection between the two. Is used. The zebra connector is a flexible band-type electrical connection part which is arranged in the transverse direction with a plurality of conductive cells made of conductive rubber or the like insulated from each other, and is useful for connecting between a plurality of electrodes.
제1도에는 종래의 조립장치의 일례가 도시되어 있다. LCD(L)와 회로모듈(M)은 홀더(H)에 의해 일체로조립되며 그 사이에 개재된 제브라 커넥터(Z)에 의해 접속되도록 되어 있다. 홀더(H)에는 상방으로 돌출된 복수의 훅(hook; h)이 구비되어, 이 훅(h)을 회로모듈(M)의 기판에 형성된 복수의 결합구멍(m)을 통해 삽입한뒤 이를 비틀어줌으로써 조립이 이뤄진다. 이에 따라 이 조립장치는 적재판(11)에 놓여진 하부블록(lowerblock; 13)상에 홀더(H)-(LCD (L)-제브라 커넥터(Z)-회로모듈(M)순으로 조립될 구성부품들을 순차적으로 얹은 뒤, 상부 블록(12)을 덮는다. 다음 이 상, 하부 블록(12, 13)을 안내부(18)를 따라 승강판(14)상으로 이동시킨뒤, 액류에이터(actuator; 15)를 상승시킴으로써 승강판(14)과 지지판(16)사이에서 상, 하부블록(12,13)을 누름으로써 조립될 각 부품을 밀착 고정시킨다. 이 상태에서 상부블록(12)에 형성된 조립구멍(12a)에 공구(T)를 삽입하여 홀더(H)의 훅(h)을 비틀어 LCD와 모듈간의조립을 완료한다.1 shows an example of a conventional assembly apparatus. The LCD L and the circuit module M are integrally assembled by the holder H, and are connected by the zebra connector Z interposed therebetween. The holder (H) is provided with a plurality of hooks (h) protruding upwards, the hook (h) is inserted through a plurality of coupling holes (m) formed in the substrate of the circuit module (M) and twisted Assembly is done by giving. Accordingly, the assembly device is a component to be assembled in the order of holder (H)-(LCD (L)-zebra connector (Z)-circuit module (M) on the lower block (13) placed on the mounting plate (11) After placing them sequentially, they cover the upper block 12. Next, the lower blocks 12 and 13 are moved along the guide portion 18 onto the lifting plate 14, and then an actuator 15 ) By pressing the upper and lower blocks 12 and 13 between the elevating plate 14 and the support plate 16 to securely close each component to be assembled. Insert the tool T into 12a) and twist the hook h of the holder H to complete the assembly between the LCD and the module.
조립이 완료된 LCD조립체는 기능검사공정으로 이송되어 접속상태의 이상유무가 검사된다.The assembled LCD assembly is transferred to a functional test process and the connection status is checked.
그런데 LCD는 점차 대형화되어 가고 있으며 표시정보밀도가 증가하고 있어 이에 따라 접속된 전극패드(pad)의 전극수도 증가하므로 그 전극간의 피치(pitch)가 더욱 줄어들어 있다. 이에따라 긴 제브라 커넥터를 사용하거나 전극 피치가 조밀한 전극패드를 접속하는 경우에는 제브라 커넥터에 의한 접속이 정확히 이뤄지기어렵게 된다. 그러나 종래에는 조립이 완료되어 기능검사 공정을 거치기 전에는 조립체의 접속이 정확히 이루어졌는가를 확인 할수가 없어서, 기능검사공정에서 불량처리된 조립체는 해체하여 접속상태를 바로잡는 수리를 행한 뒤 재조립해야 하는 불편이 있었다. 특히 기능검사 공정에서의 불량이 제브라 커넥터의 접촉불랴이 아닌 부품의 이상에 기인하는 것인 경우에도 이를 발견해낼수 없어서 조립-검사-해체-수리-재조립을 반복하여야 하므로 공정의 효율이 더욱 저하되었다. 예를 들어 제브라 커넥터가 긴, 대형 LCD를 조립하는 경우 기능검사를 통과하는 양품률은 겨우3.40%에 지나지 않았으며, 이 불량품을 해체 및 수리하여 재조립하는 수리담당자가 별도로 필요한 문제점이 있었다.However, LCDs are gradually becoming larger and display information densities are increasing. Accordingly, the number of electrodes of the connected electrode pads is also increased, so that the pitch between the electrodes is further reduced. Accordingly, when using a long zebra connector or connecting an electrode pad with a dense electrode pitch, connection by the zebra connector becomes difficult to be made accurately. However, in the prior art, it is impossible to confirm whether the assembly is correctly connected before the assembly is completed and the functional inspection process is performed. Therefore, the defective assembly is dismantled in the functional inspection process to repair and repair the connection state. There was inconvenience. In particular, even if the defect in the functional inspection process is due to the abnormality of the parts, not the contact plug of the zebra connector, it cannot be found. . For example, when assembling a large LCD with a long zebra connector, the yield rate that passed the functional test was only 3.40%, and there was a problem that a repair person who dismantled and repaired and reassembled the defective product was required separately.
본 고안은 이러한 종래의 문제점을 감안하여, LCD조립의 적정성 여부를 조립과정에서 파악하여 적절히 접속된 LCD모듈만을 조립할수 있는 LCD모듈 조립장치를 제공하는 것을 목적으로 한다.The present invention is to provide an LCD module assembly device that can assemble only the appropriately connected LCD module by grasping the appropriateness of the LCD assembly in the assembly process in view of such a conventional problem.
이러한 목적을 달성하기 위해 본 고안에 의한 LCD모듈 조립장치는 조립장치에 신호공급장치와 반사경을 구비하여 작업자가 LCD와 회로모듈을 가조립한 상태에서 신호공급장치로 LCD에 기준정보를 표시하고 이 표시되는 화상을 반사경을 통해 관찰하여 이상이 없을 때최종조립을 행하도록 하는 것을 특징으로 한다.In order to achieve this purpose, the LCD module assembly apparatus according to the present invention has a signal supply device and a reflecting mirror on the assembly device, and the operator displays the reference information on the LCD with the signal supply device while the LCD and the circuit module are assembled. It is characterized in that the final assembly is observed when there is no abnormality by observing the image through the reflector.

제2도에서, 본 고안에 의한 조립장치에서 액튜에이터(5)에 의해 승강하는 지지대(4)에 복수의 조립구멍(2a)이 형성된 상부블록(2)이 설치되고, 적재판(1)상에는 홀더(H)-LCD(L)-제브라 커넥터(Z)-회로모듈(M)이 순차적으로 적재되는 하부블록(3)이 위치하는데, 이 하부블록(3)은 안내부(8)를 따라 적재판(1)상을 이동할수 있게 되어 있다. 하부블록(3)은 적재판(1)전방의 적재위치와 상부블록(2)하부의 조립위치간을 이동할 수 있게 되어 있으며 개구부(opening; 3a)가 형성되어 적재된 LCD(L)를 하부에서 관찰 할수있도록 되어 있다.In FIG. 2, in the assembling apparatus according to the present invention, an upper block 2 having a plurality of assembling holes 2a is provided in the support 4 which is lifted by the actuator 5, and on the mounting plate 1, a holder is provided. (H) -LCD (L) -zebra connector (Z) -circuit module (M) on which the lower block (3) is placed, which is placed on the lower plate (3) along the guide (8) (1) We can move phase. The lower block 3 is able to move between the loading position in front of the loading plate 1 and the assembly position of the lower part of the upper block 2, and an opening 3a is formed and the LCD L loaded thereon is opened from below. It can be observed.
적재판(1)의 조립 위치 하부에는 이 개구부(3a)에 대응하는 투사개구부(1a)가 형성되고 그 하부에는 반사경(6)이 설치되어 있으며, 개구부(3a) 및 투사개구부(1a)의 반사경 (6)에 의한 광 반사경로상의 적재판(1)에는관찰 개구부(1b)가 형성되어 있다. 즉 하부블록(3)상에 얹힌 LCD(L)의 화상은 하부블록(3)의 개구부(3a) 및적재판(1)의 투사개구부(1a), 그리고 반사경(6)을 통해 작업자가 관찰 개구부(1b)로 관찰할수 있도록 구성되어 있다. 한편 조립을 위해 적재되는 회로모듈(M)은 커넥터(C)를 통해 신호공급장치(7)에 접속되도록 되어 있다. 또한 적재판(1)의 하부에는 관찰의 편의를 위해 조명등(9)이 구비된다.A projection opening portion 1a corresponding to this opening portion 3a is formed at the lower portion of the mounting plate 1, and a reflecting mirror 6 is provided at the lower portion thereof, and a reflection mirror of the opening portion 3a and the projection opening portion 1a is provided. The observation opening 1b is formed in the mounting plate 1 on the light reflection path by (6). That is, the image of the LCD L mounted on the lower block 3 is viewed by the operator through the opening 3a of the lower block 3, the projection opening 1a of the stacking plate 1, and the reflector 6. It is configured to observe as 1b). On the other hand, the circuit module (M) to be loaded for assembly is to be connected to the signal supply device (7) through the connector (C). In addition, the lower part of the mounting plate 1 is provided with a lamp (9) for the convenience of observation.
이러한 조립장치에 사용되는 신호공급장치(7)는 후속공정인 기능검사 공정에 사용되는 기능검사 회로에 비해간략한 구성을 가지는데, 신속하게 접속상태의 정확성을 판단할 수 있을 정도의 기준 정보를 표시할 수 있으며족하다.The signal supply device 7 used in such an assembly apparatus has a simple configuration compared to the functional test circuit used in the functional test process, which is a subsequent process, and displays reference information such that the accuracy of the connection state can be quickly determined. You can do it.
이러한 구성의 본 고안 조립장치로 LCD-모듈의 조립을 행하는 과정을 제3도를 통해 설명한다.The process of assembling the LCD module with the present invention assembly device of such a configuration will be described with reference to FIG.
적재위치에 위치한 하부블록(3)상에 흘더(H)-LCD(L)-제브라 커넥터(Z)-회로모듈(M)의 순서로 조립될 부품을 적재한다. 다음 이 회로모듈(M)에 신호공급장치(7)의 커넥터(C)를 연결한다. 다음 조립될 부품들이 적재된 하부블록(3)을 안내부(8)를 따라 조립위치로 이동시킨 뒤 액튜에이터(5)를 기동하여 지지대(4) 및 상부블록(2)이 하브블록(3)상으로 하강하도록 한다. 그러면 조립부품은 신호공급장치(7)에 접속된 상태로 상, 하부블록(2,3) 사이에서 밀착고정된다. 이 상태에서 조명등(9)을 켜고, 신호공급장치(7)를 조작하여 LCD(L)에 소정의 문자 정보가 표시되도록 한다. 그러면 LCD(L)에 표시된 문자정보의 화상은 하부블록(3)의 개구부(3a)-적재판(1)의 투사개구부(1a)-반사경(6)-적재판(1)의 관찰개구부(1b)를 통해 작업자에게 관찰된다. LCD(L)에 표시되는 정보에 이상이 없으면 정확한 접속히 이뤄진 것이므로 작업자는 상부블록(2)의 조립구멍(2a)에 공구(T)를 삽입하여 홀더(H)의 훅(h)을 비틀어 줌으로써 LCD와 모듈의 조립을 수행한다. 다음 액튜에이터(5)를 다시 기동하여 상, 하부블록(2, 3)이 열리게 한뒤, 커넥터(C)를 해체하고 LCD조립체를 반출하여 커넥터(C)를 해체하면 조립이 완료되는 것이다.The parts to be assembled are loaded in the order of Hder-LCD (L) -Zebra Connector (Z) -Circuit Module (M) on the lower block 3 located at the loading position. Next, connect the connector C of the signal supply device 7 to the circuit module M. Next, the lower block 3 loaded with the parts to be assembled is moved along the guide 8 to the assembly position, and then the actuator 5 is started to support the support block 4 and the upper block 2 on the hub block 3. To descend. Then, the assembly is tightly fixed between the upper and lower blocks 2 and 3 while being connected to the signal supply device 7. In this state, the lamp 9 is turned on, and the signal supply device 7 is operated so that predetermined character information is displayed on the LCD (L). Then, the image of the character information displayed on the LCD (L) is the opening 3a of the lower block 3-the projection opening 1a of the loading plate 1-the reflecting mirror 6-the observation opening 1b of the loading plate 1 Observed by the operator. If there is no abnormality in the information displayed on the LCD (L), the connection is made correctly. The operator inserts the tool (T) into the assembly hole (2a) of the upper block (2) and twists the hook (h) of the holder (H). Perform assembly of LCD and module. After the actuator 5 is started again, the upper and lower blocks 2 and 3 are opened, the connector C is dismantled, the LCD assembly is taken out, and the connector C is dismantled.
만일 이 검사과정에서 이상이 발견되며 상, 하부블록(2,3)을 열어 제브라 커넥터(Z)의 접촉상태를 수정한뒤 전술한 과정을 행하게된다.If an abnormality is found in this inspection process, the upper and lower blocks 2 and 3 are opened to correct the contact state of the zebra connector Z, and then the above-described process is performed.
이와 같이 본 고안에서는 구성부품들을 가조립상태에서 접촉상태를 미리 검사하여 접속이 완전한 경우에 영구조립을 행하게 된다. 이에 따라 후속공정인 기능검사공정을 통과하는 양품율이 현저하게 증가하여 종래의3.40%에 비해 2배이상인 80%이상에 이르게 된다. 이 경우 불량의 대부분은 조립접촉의 불량에 의한 것이 아니라 구성부품 자체의 불량에 의한 것이므로 실질적으로 조립접촉불량은 본 고안 조립장치에 의해 거의 방지된다고 할수 있다. 또한 별도의 수리전문 작업자도 불필요하게 되므로, 본 고안은 특히 대형, 고 정보밀도의 액정표시장치의 생산성 향상과 원가절감에 매우 현저한 효과가 있는 것이다.Thus, in the present invention, the components are inspected in advance in contact with each other in a preassembled state, and permanent assembly is performed when the connection is completed. As a result, the yield rate that passes the functional inspection process, which is a subsequent process, is remarkably increased, reaching 80% or more, which is more than twice that of the conventional 3.40%. In this case, since most of the defects are not caused by the assembly contact, but by the defect of the component itself, the assembly contact failure can be almost prevented by the assembly device of the present invention. In addition, since there is no need for a separate repair specialist, the present invention has a very remarkable effect on productivity and cost reduction of a large, high information density liquid crystal display device.
