본 고안은 LCD 기판의 배향막 러빙 (Rubbing) 가공시 발생되는 정전기를 제거하는 장치에 관한 것이다.The present invention relates to an apparatus for removing static electricity generated during the rubbing processing of an alignment film of an LCD substrate.
LCD의 제조공정중, 러빙천에 의한 배향막의 가공후에는 러빙천의 연마에 따른 정전기가 기판에 많이 발생된다. 이 발생된 정전기는 기판을 작업 바닥면에서 분리할때 방전이 일어나 유리기판, 기판에 형성시킨 전극 및 배향막에 손상을 가져오고 심할경우 기판이 파손되는 경우도 발생한다. 그리고 그 정전기는 주위의 기기들에도 나쁜 영향을 미치고 있다.During the manufacturing process of the LCD, after processing the alignment film by the rubbing cloth, a lot of static electricity generated by polishing of the rubbing cloth is generated on the substrate. The generated static electricity discharges when the substrate is separated from the work floor, which causes damage to the glass substrate, the electrodes formed on the substrate, and the alignment layer, and in some cases, the substrate is broken. And the static electricity is bad for the devices around it.
이를 예방하기 위한 종래의 정전기 예방기구로는 제전바를 별도로 설치하여 극소적으로 기판과 접촉시키거나 이온블로우어 (ION BLOWER)를 설치하여 방전을 예방하고 정전기를 일부제거하여 왔으나, 이것 역시 정전기를 완전히 제거하지는 못하는 문제가 있었다.Conventional anti-static mechanisms to prevent this have been installed separately from the antistatic bar to contact the substrate or by installing an ion blower (ION BLOWER) to prevent the discharge and remove some of the static electricity, but this also completely There was a problem that could not be removed.
본 고안은 상술한 문제점을 감안하여 안출한 것으로, 본 고안의 목적은 러빙작업후에 발생한 정전기를 완전히 제거할 수 있는 장치를 제공하는 것이다.The present invention has been made in view of the above problems, and an object of the present invention is to provide an apparatus capable of completely removing the static electricity generated after the rubbing operation.
상술한 목적을 달성하기 위한 본 고안의 주요수단은, 리빙롤(4)에서 발생되는 정전기를 중화시키는 제전부재(6)와, 러빙롤(4)에 의해 작업완료된 기판(1)의 한쪽면을 작업대(2)에서 들어올리는 푸셔핀(8)과, 들어올려진 기판(1)과 작업대 (2) 사이에 송풍작동하도록 설치하는 에어블로우어(9)로 구성되는 것을 주요특징으로 한다.The main means of the present invention for achieving the above object is, one side of the substrate 1 completed by the antistatic member 6 and the rubbing roll 4 to neutralize the static electricity generated in the living roll (4) The main feature of the present invention consists of a pusher pin (8) lifting from the work table (2), and an air blower (9) installed to blow air between the lifted substrate (1) and the work table (2).
이하 본 고안의 구성을 첨부도면에 의거 설명하면 다음과 같다.Hereinafter, the configuration of the present invention will be described based on the accompanying drawings.
제 1 도 및 제 2 도는 본 고안의 정전기 제거장치에 따른 작동도이다.1 and 2 is an operation diagram according to the static eliminator of the present invention.
유리기판 (1) 이 작업대 (2) 에 놓이고, 기판위에 형성된 배향막(3)은 러빙롤(4)에 의해 가공된다. 이때 러빙롤(4)의 회전에 의해 배향막(3)이 가공될때 마찰에 의한 정전기가 발생되는바, 이를 방지하기 위해 러빙롤(4)의 측부에 긴 바 형태의 제전부재(6)를 설치하였다. 제전부재(6)에는 + 또는 - 이온을 방출하는 여러 탐침을 설치하였다. 따라서, 도시하지 않은 정전기 감지장치가 음 또는 양전기의 발생을 감지하면, 제전부재(6)에서 역으로 양 또는 음이온을 선택적으로 방출토록하여 발생된 전기를 중화시켜 버린다.The glass substrate 1 is placed on the work table 2, and the alignment film 3 formed on the substrate is processed by the rubbing roll 4. At this time, when the alignment film 3 is processed by the rotation of the rubbing roll 4, static electricity generated by friction is generated. In order to prevent this, a long bar-type antistatic member 6 is installed on the side of the rubbing roll 4. . The antistatic member 6 was provided with various probes for releasing + or-ions. Therefore, when the electrostatic sensing device (not shown) detects the generation of negative or positive electric charges, the antistatic member 6 reverses the positive or negative ions, thereby neutralizing the generated electricity.
상술한 작동후에는 기판(1)의 아래쪽에 설치한 푸셔핀(8)에 의해 기판(1)의 한쪽 모서리가 들려올려진다. 이때 기판(1)과 작업대(2) 두 면 사이에 발생되어 있는 정전기는 올려진 기판(1)과 작업대(2) 사이에 위치시킨 에어블로우어(9)의 송풍에 의해 기판(1)의 대전입자가 작업대(2)로 쏠리게 하는데 (접지) 보조하여 주고 상술한 제전부재(6)의 작동에 의해 발생된 정전기를 완전히 중화시켜 버린다. 에어블로우어(9)의 뒤에는 깨끗한 공기의 송풍을 위해 공기필터(5)를 설치한다.After the above-described operation, one edge of the substrate 1 is lifted by the pusher pin 8 provided below the substrate 1. At this time, the static electricity generated between the two surfaces of the substrate 1 and the work table 2 is charged by the air blower 9 positioned between the raised substrate 1 and the work table 2. It assists (grounding) the particles to be directed to the work table 2 and completely neutralizes the static electricity generated by the operation of the antistatic member 6 described above. Behind the air blower (9) is installed an air filter (5) for blowing clean air.
이상과 같은 본 고안의 장치구성에 의하면 러빙공정에 의해 발생되는 정전기를 완전제거할 수 있어, 작업대(2)와 기판(1)의 분리시 발생되는 방전에 의한 패턴손상들의 기판상의 손상이나 기판에 미치는 나쁜영향을 완전히 방지 할 수 있는 효과가 있다.According to the device configuration of the present invention as described above, it is possible to completely eliminate the static electricity generated by the rubbing process, and to damage the substrate or the substrate damage of the pattern damages caused by the discharge generated when the worktable 2 and the substrate 1 are separated. The effect is to completely prevent the bad effect.
상술한 본 고안은 설명은 한가지의 구조예를 들어 구체적으로 설명하였지만 본 고안의 기술 사상범위내에서 여러 변형 실시할 수 있음은 물론이다. 한 예로서, 제전부재(6)의 설치구조나 위치 등은 장치의 구조 또는 구성상 편의에 따라 여러 변형이 가능하고 구성요소의 장치 자체의 구조도 여러 변형가능하다. 그리고 상술한 장치의 설명은, 설명상 주요구성 요소에 대하여만 설명하였지만 이를 하나의 케이스체 형태로 장치를 형성시켜 사용하는 것이 바람직하다.The present invention described above has been described in detail by taking one structural example, but of course, various modifications can be made within the technical idea of the present invention. As an example, the installation structure or position of the antistatic member 6 may be variously modified according to the structure or configuration convenience of the device, and the structure of the device itself of the component may be variously modified. In addition, although the description of the apparatus described above has been described only for the main components, it is preferable to use the apparatus in the form of a case body.
