액정표시소자의 배향용액 인쇄장치Alignment solution printing device for liquid crystal display device

본 발명은 액정표시소자의 배향용액 인쇄장치에 관한 것으로, 특히 용액 점도 변화에 따른 배향막 두께 변화 및 인쇄 얼룩 불량을 해소하도록 한 액정표시소자의 배향용액 인쇄장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alignment solution printing apparatus for a liquid crystal display device, and more particularly, to an alignment solution printing apparatus for a liquid crystal display device to solve a change in thickness of an alignment film caused by a change in solution viscosity and a defect in printing.

투명전극을 갖는 2매의 유리기판 사이에 봉입된 액정을 일정한 각도로 배향시키기 위하여 배향제를 인쇄하는 배향용액 인쇄장치의 전형적인 일 실시형태가 제 1도에 도시되어 있는 바, 이를 간단히 살펴보면 다음과 같다.An exemplary embodiment of an alignment solution printing apparatus for printing an alignment agent to orient liquid crystals enclosed between two glass substrates having transparent electrodes at a predetermined angle is shown in FIG. 1. same.

제 1도에 도시한 바와 같이, 일반적인 액정표시소자의 배향용액 인쇄장치는 투명전극을 형성한 유리기판(1)위에 인쇄롤러(2)가 위치해 있고, 이 인쇄롤러(2)의 표면에 인쇄수지판(3)이 부착되어 있으며, 상기 인쇄롤러(2)의 상부에는 배향용액이 균일한 두께로 인쇄되도록 눌러주는 아니록스롤러(4)가 위치해 있고, 배향용액을 주사시키는 주사기(5)와, 상기 주사기(5)를 좌,우로 이동시키기 위한 모터(6)를 포함하는 이동수단과, 주사된 배향용액을 균일하게 분포시키기 위한 닥터블레이드(7) 및 상기 닥터블레이드(7)가 유동하지 않도록 고정하는 닥터블레이드고정대(8)가 상기 아니록스롤러(4)의 상단에 배치된 구조로 되어 있다.As shown in FIG. 1, in a general liquid crystal display device alignment liquid printing device, a printing roller 2 is placed on a glass substrate 1 on which a transparent electrode is formed, and a printing resin is placed on the surface of the printing roller 2. A plate 3 is attached, and an anilox roller 4 for pressing the alignment solution is printed on the printing roller 2 so as to have a uniform thickness, and a syringe 5 for injecting the alignment solution, Moving means including a motor (6) for moving the syringe (5) to the left and right, and the doctor blade (7) and the doctor blade (7) to uniformly distribute the injected alignment solution is fixed so as not to flow The doctor blade fixing stand 8 has a structure arranged on the upper end of the anilox roller 4.

상기 모터(6)는 한쌍의 레일(9)을 따라 좌,우 이동하도륵 설치되어 있고, 상기 모터(6)의 하부에 주사기(5)가 부착되어 좌,우 방향으로 이동하게 되어 있는 것이다.The motor 6 is installed to move left and right along the pair of rails 9, and the syringe 5 is attached to the lower part of the motor 6 to move in the left and right directions.

상기와 같이 구성된 종래 배향용액 인쇄장치에 의한 인쇄방법을 제 2도를 참조하여 살며보면 다음과 같다.Looking at the printing method by the conventional alignment solution printing apparatus configured as described above with reference to Figure 2 as follows.

배향용액(10)이 주사기(5)를 통하여 주사되면, 이 주사기(5)는 모터(6)에 의해 도면의 우측으로 이동하면서 아니록스롤러(4)에 배향용액을 주사하게 된다.When the alignment solution 10 is injected through the syringe 5, the syringe 5 moves to the right side of the drawing by the motor 6 to inject the alignment solution into the anilox roller 4.

배향용액 주사가 완료되면 모터(6)에 의해 주사기(5)는 도면의 좌측으로 이동하여 원위치하게 되고, 이어서 유리기판(1)이 글래스 진행방향으로 투입된다.When the injection of the alignment solution is completed, the syringe 5 is moved to the left side of the drawing by the motor 6, and then the glass substrate 1 is introduced in the glass advancing direction.

상기와 같이 유리기판(1)이 투입되면, 아니록스롤러(4)와 인쇄롤러(2)가 각각 회전[아니록스롤러(4)는 글래스 진행방향의 반대방향, 인쇄롤러(2)는 글래스 진행방향으로 회전한다]하게 되는데, 이때 배향용액은 아니록스롤러(4)의 상단에 위치한 닥터블레이드(7)에 의해 아니록스롤러(4)에 흡착되어 균일하게 전사된다.When the glass substrate 1 is inserted as described above, the anilox roller 4 and the printing roller 2 are rotated respectively (the anilox roller 4 is in the opposite direction of the glass advancing direction, and the printing roller 2 is glass advancing). Direction of rotation], wherein the alignment solution is adsorbed to the anilox roller 4 by the doctor blade 7 located at the top of the anilox roller 4 and is uniformly transferred.

아니록스롤러(4)의 표면에 흡착된 배향용액은 인쇄롤러(2)에 부착된 인쇄수지판(3)의 표면에 접촉하면서 재흡착되고, 이와 같이 배향용액이 흡착된 인쇄수지판(3)과 유리기판(1)이 서로 접촉하면서 유리기판(1)의 표면에 배향용액을 인쇄시키게 되며, 유리기판(1)의 인쇄가 완료되면 다시 배향용액이 주사기(5)를 통하여 주사되는 과정으로 공정이 진행되는 것이다.The alignment solution adsorbed on the surface of the anilox roller 4 is resorbed while contacting the surface of the printing resin plate 3 attached to the printing roller 2, and the printing resin plate 3 on which the alignment solution is adsorbed is thus adsorbed. And the glass substrate 1 are in contact with each other to print the alignment solution on the surface of the glass substrate 1, and when the printing of the glass substrate 1 is completed, the alignment solution is injected again through the syringe (5) This is going on.

그러나 상기한 바와 같은 종래의 배향용액 인쇄장치에 있어서는, 배향용액이 아니록스롤러(4)의 상단부에서 주사되고, 주사기(5)와 아니록스롤러(4)와의 간격이 5cm 이상으르 유지되어 있으므로 용액이 주사되고 난 후, 용액의 점도가 변하게 되고, 아니록스롤러(4)의 상단부에 잔존되어 있는 용액 위에 새로운 용액이 주사되어 부분적으로 용액의 양과 점도의 차이가 발생되므로 인쇄방향으로의 줄무늬 및 막의 얼룩이 발생하는 등의 문제가 있었다.However, in the conventional alignment solution printing apparatus as described above, the alignment solution is injected at the upper end of the anilox roller 4, and the distance between the syringe 5 and the anilox roller 4 is maintained at 5 cm or more. After the injection, the viscosity of the solution is changed, and a fresh solution is injected onto the remaining solution at the upper end of the anilox roller 4 so that a partial difference in the amount and viscosity of the solution is generated. There was a problem such as staining.

또 종래의 장치는 닥터블레이드(7)가 고정되어 있어 아니록스롤러(4)에 결점이 생길 경우 그 형상이 그대로 인쇄면에 전사되므로 인쇄불량을 야기시키는 문제가 있었다. 이는 액정표시소자의 특성에 가장 중요한 화면의 균일성(uniformity)에 영향을 끼치므로 이의 제거가 요구되었다.In addition, in the conventional apparatus, when the doctor blade 7 is fixed and a defect occurs in the anilox roller 4, its shape is transferred to the printing surface as it is, which causes a problem of printing failure. Since this affects the uniformity of the screen which is most important to the characteristics of the liquid crystal display device, it is required to remove it.

이를 감안하여 창안한 본 발명의 목적은 주사기를 통하여 주사되는 배향용액이 아니록스롤러의 잔존용액 중에 주사되게 함으로써 인쇄방향의 줄무늬 불량 및 막의 얼룩 불량을 제거하여 보다 균일한 두께의 배향막을 얻을 수 있도록 한 액정표시소자의 배향용액 인쇄장치를 제공함에 있다.In view of this, an object of the present invention is to inject the alignment solution injected through the syringe into the remaining solution of the anilox roller so as to remove streaks in the printing direction and defects in the film to obtain an alignment film having a more uniform thickness. The present invention provides an alignment solution printing apparatus for a liquid crystal display device.

이하, 상기한 바와 같은 본 발명에 의한 액정표시소자의 배향용액 인쇄장치의 작용 및 효과를 설명한다.Hereinafter, the operation and effects of the alignment solution printing apparatus of the liquid crystal display device according to the present invention as described above will be described.

본 발명 장치의 기본적인 인쇄방법은 종래와 동일하다.The basic printing method of the apparatus of the present invention is the same as in the prior art.

즉, 배향용액(10)이 주사기(5)를 통하여 주사되면, 이 주사기(5)는 모터(6)에 의해 도면의 우측으로 이동하면서 아니록스롤러(4)에 배향용액을 주사하게 된다.That is, when the alignment solution 10 is injected through the syringe 5, the syringe 5 moves to the right side of the drawing by the motor 6 to inject the alignment solution into the anilox roller 4.

배향용액 주사가 완료되면 모터(6)에 의해 주사기(5)는 도면의 좌측으로 이동하여 원위치하게 되고, 이어서 유리기판(1)이 글래스 진행방향으로 투입된다.When the injection of the alignment solution is completed, the syringe 5 is moved to the left side of the drawing by the motor 6, and then the glass substrate 1 is introduced in the glass advancing direction.
