본 고안은 액정 유리기판의 표면 건조장치에 관한 것으로서, 특히 액정 유리기판을 세정한 후 압축공기를 분사하여 건조시키는 에어 나이프(air knife)의 기류 가이드를 부착하여 워터 마크(water mark) 및 파티클(particle)을 방지하도록 하는 액정 유리기판의 표면 건조장치에 관한 것이다.The present invention relates to a surface drying apparatus of a liquid crystal glass substrate, and in particular, a water mark and a particle (attached) by attaching an air knife guide of an air knife to clean and dry the liquid crystal glass substrate by spraying compressed air. It relates to a surface drying apparatus of a liquid crystal glass substrate to prevent particles).
종래의 액정 유리기판의 표면 건조장치는 제1도에 도시된 바와 같이 액정 유리기판(1)을 반송시키는 구동롤러(2)와, 상기 액정 유리기판(1)에 압축공기를 분사하여 액정 유리기판(1) 표면의 수분을 제거/건조시키는 에어 나이프(3)로 구성된다.The surface drying apparatus of the conventional liquid crystal glass substrate has a driving roller (2) for conveying the liquid crystal glass substrate (1) as shown in FIG. 1 and a liquid crystal glass substrate by spraying compressed air onto the liquid crystal glass substrate (1). (1) It consists of the air knife 3 which removes / drys the surface moisture.
상기와 같이 구성된 액정 유리기판의 표면 건조장치는 제2도에 도시된 바와 같이 세정된 액정 유리기판(1)은 구동롤러(2)에 의해 반송되면서 에어 나이프(3)에서 분사되는 압축공기에 의해 표면의 수분(4)이 기판의 외곽으로 이동되고 그후 건조된다.In the surface drying apparatus of the liquid crystal glass substrate configured as described above, the liquid crystal glass substrate 1 cleaned as shown in FIG. 2 is conveyed by the driving roller 2 and is compressed by the compressed air sprayed from the air knife 3. Moisture 4 on the surface is moved to the outside of the substrate and then dried.
그러나, 상기한 종래의 액정 유리기판의 표면 건조장치는 에어 나이프(3)에서 분사되는 압축공기에 의해 액정 유리기판(1) 표면의 수분(4)이 건조되는 과정에서 액정 유리기판(1)의 표면 위로 기류층(5)이 형성된다. 상기 기류층(5)은 상기 액정 유리기판(1)의 외곽으로 이동중인 수분(4)을 증발시킨다. 이로 인해 액정 유리기판(1)의 표면에는 워터 마크가 발생한다는 문제점이 있었다.However, the above-described surface drying apparatus of the liquid crystal glass substrate of the liquid crystal glass substrate 1 in the process of drying the moisture (4) on the surface of the liquid crystal glass substrate (1) by the compressed air injected from the air knife (3) The airflow layer 5 is formed on the surface. The air flow layer 5 evaporates the water 4 moving to the outside of the liquid crystal glass substrate 1. For this reason, there was a problem in that a water mark is generated on the surface of the liquid crystal glass substrate 1.
또한, 에어 나이프(3)에서 분사되는 압축공기가 액정 유리기판(1)의 표면에 강하게 부딪치어 액정 유리기판(1)의 표면에 난류(6)가 형성된다. 상기 난류(6)는 수분(4)이 액정 유리기판(1)의 외곽으로 밀리는 것을 방해하고, 수분(4)의 표면장력을 약하게 하여 일부 수분 방울을 수분(4)으로부터 분리시켜 액정 유리기판(1) 표면을 유동하게 만들기 때문에 액정 유리기판(1)의 미건조 및 파티클을 발생시킨다는 문제점이 있었다.In addition, the compressed air jetted from the air knife 3 strongly strikes the surface of the liquid crystal glass substrate 1, so that turbulence 6 is formed on the surface of the liquid crystal glass substrate 1. The turbulence 6 prevents the moisture 4 from being pushed to the outside of the liquid crystal glass substrate 1, weakens the surface tension of the moisture 4 to separate some drops of moisture from the moisture 4, and thus the liquid crystal glass substrate ( 1) Since the surface is made to flow, there is a problem in that the liquid crystal glass substrate 1 is undried and generates particles.
따라서, 본 고안은 상기한 종래기술의 문제점을 해결하기 위해 안출된 것으로서, 압축공기를 에어 나이프를 통해 분사하여 액정 유리기판을 건조시킬때 발생되는 기류층과 난류를 억제하고, 이로 인해 중간 건조와 미건조를 방지하여 워터마크 및 파티클이 발생하지 않도록 하여 고품질의 액정 유리기판을 생산할 수 있도록 하는 액정 유리판의 표면 건조장치를 제공하는데 그 목적이 있다.Therefore, the present invention is devised to solve the above problems of the prior art, and suppresses the air flow layer and turbulence generated when the liquid crystal glass substrate is dried by injecting compressed air through an air knife, and thus intermediate drying and It is an object of the present invention to provide a surface drying apparatus of a liquid crystal glass plate that prevents undrying and prevents watermarks and particles from being generated to produce high quality liquid crystal glass substrates.
상기한 목적을 달성하기 위한 본 고안의 액정 유리기판의 표면 건조장치는 액정 유리기판을 반송시키는 구동롤러와, 상기 액정 유리기판에 압축공기를 분사하여 액정 유리기판 표면의 수분을 제거/건조시키는 에어 나이프와, 상기 에어 나이프의 상면에 부착되어 상기 압축공기에 의한 기류층 및 난류 형성을 억제시키는 기류 가이드로 구성된 것을 특징으로 한다.The surface drying apparatus of the liquid crystal glass substrate of the present invention for achieving the above object is a drive roller for conveying the liquid crystal glass substrate, and air to remove / dry the water on the surface of the liquid crystal glass substrate by spraying compressed air to the liquid crystal glass substrate And an airflow guide attached to an upper surface of the air knife to suppress the formation of an airflow layer and turbulence by the compressed air.
이하, 첨부한 도면을 참조하여 본 고안의 실시예를 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 고안에 의한 액정 유리기판의 표면 건조장치는 제3도에 도시된 바와 같이 액정 유리기판(11)을 반송시키는 구동롤러(12)와, 상기 액정 유리기판(11)에 압축공기를 분사하여 액정 유리기판(11) 표면의 수분(16)을 제거/건조시키는 에어 나이프(13)와, 상기 에어 나이프(13)의 상면에 부착되어 상기 압축공기에 의한 기류층 및 난류 형성을 억제하는 기류 가이드(14)로 구성된다.The surface drying apparatus of the liquid crystal glass substrate according to the present invention has a driving roller 12 for conveying the liquid crystal glass substrate 11 and compressed air to the liquid crystal glass substrate 11, as shown in FIG. An air knife 13 for removing / drying water 16 on the surface of the glass substrate 11 and an air flow guide attached to an upper surface of the air knife 13 to suppress the formation of an air flow layer and turbulence by the compressed air ( 14).
또한, 상기 에어 나이프(13)는 기류 가이드(14)로 상하로 이동하는 통로인 가이드와, 상기 기류 가이드(14)를 상기 에어 나이프(13)에 고정시키는 고정볼트(15)를 포함하여 구성하므로, 압축공기에 의해 형성되는 층류가 액정 유리기판(11) 표면으로부터 수평하고 상기 층류의 높이가 조절될 수 있도록 상이 기류 가이드(15)가 상하로 이동할 수 있도록 한다.In addition, the air knife 13 comprises a guide which is a passage for moving up and down by the airflow guide 14 and a fixing bolt 15 for fixing the airflow guide 14 to the air knife 13. In order to allow the laminar flow formed by the compressed air to be horizontal from the surface of the liquid crystal glass substrate 11 and the height of the laminar flow can be adjusted, the different air flow guides 15 can move up and down.
상기와 같이 구성된 본 고안의 액정 유리기판의 표면 건조장치는 세정된 액정 유리기판(11)은 구동롤러(12)에 의해 반송된다. 에어 나이프(13)에서 분사되는 압축공기는 기류 가이드(15)에 의해 액정 유리기판(11)표면에서 난류가 발생되지 않도록 기판의 표면에 수평한 층류로 형성된다. 수평한 층류로 형성된 상기 압축공기는 액정 유리기판(11)표면의 수분을 외곽으로 이동시킨 후 건조시킨다.In the surface drying apparatus of the liquid crystal glass substrate of the present invention configured as described above, the cleaned liquid crystal glass substrate 11 is conveyed by the driving roller 12. The compressed air jetted from the air knife 13 is formed by a laminar flow horizontal to the surface of the substrate so that turbulence does not occur on the surface of the liquid crystal glass substrate 11 by the airflow guide 15. The compressed air formed by the horizontal laminar flow is dried after moving the moisture on the surface of the liquid crystal glass substrate 11 to the outside.
상기 기류 가이드(14)는 고정볼트(15)에 의해 고정되는데 상기 고정볼트(15)를 반시계 방향으로 회전시킨 후 기류 가이드(15)를 상하로 조정하고 시계방향으로 회전시켜 고정한다. 고정볼트(15)가 시계 방향으로 회전하면서 기류 가이드(14)의 홈부분의 나사선을 타고 체결된 후 고정볼트(15)가 에어 나이프(13)의 하단면과 밀착되면 상기 에어 나이프(13)와 기류 가이드(14)는 고정된다.The airflow guide 14 is fixed by the fixing bolt 15. After the fixing bolt 15 is rotated in the counterclockwise direction, the airflow guide 15 is adjusted up and down and fixed by rotating in the clockwise direction. When the fixing bolt 15 is rotated in the clockwise direction and fastened by screwing in the groove of the airflow guide 14, and the fixing bolt 15 is in close contact with the bottom surface of the air knife 13, the air knife 13 and The airflow guide 14 is fixed.
상기한 본 고안에 의한 액정 유리기판의 표면 건조장치는 압축공기를 에어 나이프를 통해 분사하여 액정 유리기판을 건조시킬때 발생되는 기류층과 난류를 억제하고, 이로 인해 중간 건조와 미건조를 방지하여 워터마크 및 파티클이 발생하지 않도록 하여 고품질의 액정 유리기판을 생산할 수 있다는 효과가 있다.The surface drying apparatus of the liquid crystal glass substrate according to the present invention suppresses the air flow layer and turbulence generated when the liquid crystal glass substrate is dried by spraying compressed air through an air knife, thereby preventing intermediate drying and undrying. There is an effect that can produce a high-quality liquid crystal glass substrate by preventing the generation of watermarks and particles.
