도광판의 패턴가공용 레이저장치{ Laser machine for engraving pattern on a light guide plate}Laser machine for engraving pattern on a light guide plate

본 고안은 레이저장치에 관한 것으로, 특히 TFT-LCD 패널용 도광판의 표면에 패턴을 형성하기 위한 레이저장치에 관한 것이다.The present invention relates to a laser device, and more particularly, to a laser device for forming a pattern on the surface of a light guide plate for a TFT-LCD panel.

현재 컴퓨터나 TV의 디스플레이장치로서, TFT-LCD가 널리 사용되고 있고, 전자통신제품의 종류가 다양해짐에 따라 상기 LCD패널의 크기도 다양해지고 있다. 이러한 LCD패널의 일부를 구성하는 도광판은 현재 주로 투명 아크릴판을 사용하고, 표면에는 여러가지 방법으로 패턴을 형성하고 있다. 도광판의 표면에 패턴을 형성하는 방법에는 인쇄에 의한 방식과, 절삭에 의한 방식과, 레이저로써 가공하는 방식이 있다.Currently, TFT-LCD is widely used as a display device of a computer or a TV. As the types of electronic communication products are diversified, the size of the LCD panel is also diversified. The light guide plate constituting a part of the LCD panel is currently mainly using a transparent acrylic plate, and forms a pattern on the surface in various ways. The method of forming a pattern on the surface of the light guide plate includes a printing method, a cutting method, and a laser processing method.

중형 또는 대형 LCD패널에 사용되는 중대형 도광판은 주로 인쇄에 의한 방법이 사용되고 있으나, 인쇄에 의한 방법은 패턴을 형성하지 않을 부분에 마스킹을 하고 그 위에 인쇄방식으로 패턴을 형성하는 과정중에 마스크와 도광판표면 사이로 패턴액이 스며들어 발생하는 불량율이 높아서 작업에 숙련자가 필요하고, 휘도가 낮은 단점이 있다.The medium to large sized light guide plate used for the medium sized or large sized LCD panel is mainly used by printing. However, the printing method uses a mask and the surface of the mask and the light guide plate during the process of forming the pattern on the portion that will not form the pattern. The defect rate caused by the penetration of the pattern liquid is high, the skilled person is required for the work, there is a disadvantage that the brightness is low.

그리고 V형 커터로써 기계적인 절삭에 의한 방식은 가공시간이 길어 생산능률이 낮고, 절삭커터의 제어방향이 단순하여 단순한 패턴 형성에는 어느정도 적합하나 다양한 형태의 패턴을 형성하기는 어려운 단점이 있다.In addition, the V-type cutter is mechanically cut because of a long processing time, low production efficiency, and a simple control direction of the cutting cutter, which is suitable for simple pattern formation, but it is difficult to form various patterns.

따라서 현재에는 레이저가공에 의한 패턴형성방법이 선호되고 있다. 그런데 종래 레이저가공에 의한 방식에는 레이저헤드의 이동시킬 때 볼스크류에 의한 이동제어방식을 채택하고 있어 중대형 도광판의 경우, 예컨대 17인치 모니터용 도광판에 패턴을 형성하는 데 작업속도가 매우 느려(통상 5~6분/개) 양산에 적합하지 않은 단점이 있다. 또 만약 작업속도를 높이기 위해 레이저헤드를 V벨트 구동방식을 채택하는 경우도 있지만 이 경우는 작업속도는 높일 수 있지만 패턴을 직선형 패턴이외의 패턴으로 형성하기는 불가능하다.Therefore, the pattern formation method by laser processing is currently preferred. However, in the conventional laser processing method, the movement control method by the ball screw is adopted when the laser head is moved. In the case of the medium-large light guide plate, for example, the work speed is very slow to form a pattern on the light guide plate for a 17-inch monitor. ~ 6 minutes / piece) There is a disadvantage that is not suitable for mass production. In addition, if the V-belt driving method is adopted in order to increase the working speed, in this case, the working speed can be increased, but it is impossible to form a pattern other than a straight pattern.

특히, 도광판의 패턴형성용을 사용되는 종래의 레이저가공기는 범용 레이저 가공기로써 1대의 장비에서 1개의 도광판만을 패턴가공할 수 있을 뿐이므로 작업능률이 다른 패턴형성방법에 비하여 현저히 낮은 문제점을 가지고 있다.In particular, the conventional laser processing machine used for pattern formation of the light guide plate is a general-purpose laser processing machine, and since only one light guide plate can be patterned in one device, the work efficiency is significantly lower than that of other pattern formation methods.

이에 본 고안은 상기 종래 도광판의 패턴 가공장치가 가진 단점을 해소하기 위하여 고안된 것으로, 레이저로써 다양한 패턴을 도광판에 형성할 수 있으며, 작업능률도 배가하여 생산효율을 높일 수 있고, 제작단가도 저렴한 도광판 패턴가공용 레이저장치를 제공함에 목적이 있다.The present invention is designed to solve the disadvantages of the conventional pattern processing apparatus of the light guide plate, it is possible to form a variety of patterns on the light guide plate as a laser, to increase the production efficiency by doubling the work efficiency, manufacturing cost is also low cost light guide plate An object of the present invention is to provide a laser device for pattern processing.

Therefore, as the belt drive motor 15 rotates forward or reverse, the belt 14 is driven on the x-axis guide rail 13 in the x-axis direction. In addition, one laser head 16 is attached to the upper surface of the belt 14. Accordingly, the belt 14 transfers the laser head 16 attached thereon along the x axis direction while moving along the x axis direction by the rotation of the belt drive motor 15.

그리고 상기 x축가이드레일(13)의 가장자리에는, 상기 레이저발생기(10)에서 조사되는 레이저빔을 반사하여 x축가이드레일(13)상에 설치된 레이저헤드(16)로 전달하는 반사거울(17)이 고정설치되어 있다.On the edge of the x-axis guide rail 13, a reflection mirror 17 reflecting the laser beam irradiated from the laser generator 10 and transmitting it to the laser head 16 installed on the x-axis guide rail 13 This is fixed.

또한 상기 x축가이드레일(13)의 저면에는 집진용 덕트(18)가 구비되어 상기 테이블(1)위에 설치된 도광판(W1,W2)에 레이저빔으로써 패턴성형시 발생하는 연기를 흡입하여 외부로 배출하게 되어 있다.In addition, the bottom surface of the x-axis guide rail 13 is provided with a dust collecting duct 18 to suck the smoke generated during the pattern molding by the laser beam to the light guide plate (W1, W2) provided on the table (1) to discharge to the outside It is supposed to be done.

상기한 바와 같이 구성된 본 고안의 도광판 패턴가공장치에 의하면, 테이블위에 2개의 도광판을 로딩하고, x축가이드레일에 구비된 각각의 레이저헤드에서 각 도광판에 레이저빔을 조사하면서 상기 2개의 레이저헤드를 x축이송장치와 y축이송장치로써 동시에 이송제어함으로써 2개의 도광판에 동일한 패턴을 동시에 성형할 수 있으므로 작업능률을 2배로 증대시킬 수 있어 생산성을 향상시킬 수 있다.According to the light guide plate pattern processing apparatus of the present invention configured as described above, the two laser heads are loaded while two light guide plates are loaded on a table, and each laser head provided on the x-axis guide rail is irradiated with a laser beam to each light guide plate. By simultaneously controlling the feed by the x-axis feeder and the y-axis feeder, the same pattern can be simultaneously formed on two light guide plates, thereby increasing the work efficiency twice and improving productivity.

그리고 x축 이송속도는 빠르고, y축 이송속도는 볼스크류로써 정밀하게 제어함으로써 단순한 직선 패턴에서 벗어나 다양한 패턴을 빠르게 형성할 수 있는 장점이 있다.In addition, the x-axis feedrate is fast, and the y-axis feedrate is precisely controlled by using a ball screw, which has the advantage of rapidly forming various patterns away from a simple straight line pattern.
