유리기판의 모서리 가공장치 및 그를 이용한 가공방법Glass substrate edge processing device and processing method using the same
본 발명은 유리기판의 모서리 가공장치 및 그를 이용한 유리기판 모서리의 가공방법에 관한 것이다.The present invention relates to an edge processing apparatus for a glass substrate and a method for processing a glass substrate edge using the same.
평판표시장치 등에 사용되는 유리기판의 가공에는 일반적으로 유리기판을 원하는 형태로 절단한 후 절단된 유리기판의 모서리를 연삭 및/또는 연마하여 날카로운 구석을 제거하는 공정이 수반된다.Processing of glass substrates used in flat panel displays or the like generally involves cutting a glass substrate into a desired shape and then grinding and / or polishing the edges of the cut glass substrate to remove sharp corners.
상기와 같은 일반적인 가공방법에 의하면 유리기판의 모서리를 가공하는 동안 발생된 입자들이 유리기판의 표면을 오염시키므로, 이를 세척하기 위하여 세정과 건조 공정이 요구되게 되며, 이에 따라 유리기판의 제조비용이 증가된다. 또한, 가공시 벨트와 유리기판 사이에 잡힌 입자들과 칩들이 유리기판의 표면을 심각하게 손상시키므로, 종종 일련의 가공단계를 중단시키는 원인을 야기한다. According to the general processing method as described above, since particles generated during processing of the edge of the glass substrate contaminate the surface of the glass substrate, cleaning and drying processes are required to clean the glass substrate, thereby increasing the manufacturing cost of the glass substrate. do. In addition, particles and chips caught between the belt and the glass substrate during processing seriously damage the surface of the glass substrate, often causing a series of processing steps to be interrupted.
대한민국 특허출원 제2001-0085114호에서는 다이아몬드 휠을 이용하여 유리기판의 모따기를 진행하면서, 모따기 가공 부위에 인접하게 노즐을 설치하고, 노즐을 통해서 송풍해서 가루를 날려주고, 모따기 가공 중 발생한 미세 유리입자가 포함된 압축공기를 흡입하는 방법을 개시하고 있다.In Korean Patent Application No. 2001-0085114, while chamfering a glass substrate using a diamond wheel, a nozzle is installed adjacent to the chamfering process, blown through the nozzle to blow powder, and fine glass particles generated during chamfering processing Disclosed is a method of sucking the contained compressed air.
그러나, 연삭 혹은 모따기를 이용하여 모서리를 가공하는 경우, 유리가루의 발생을 피할 수 없고, 연삭과정에서 모서리의 깨짐불량, 유리가루 분진에 의한 표면 긁힘 문제, 및 작업자가 유리 분진에 노출되는 문제 등을 피할 수 없다.However, when the edges are processed by grinding or chamfering, the generation of glass powder cannot be avoided, and the cracking of the edges during the grinding process, the surface scratching problem caused by the glass dust, and the worker's exposure to the glass dust, etc. Can not be avoided.
대한민국 특허출원 제2012-0002573호에서는, 도 1에 도시된 바와 같이, 냉각된 유리기판의 모서리에 가열된 부재를 접촉시키면서 이동시킴으로써 모서리를 스트립 형태로 절취할 수 있는 방법을 개시하고 있다. 이 방법은 유리기판의 모서리 연마시 발생되는 유리 분진을 원천적으로 방지할 수 있어서 이 분야에서 유용하게 사용될 수 있을 것으로 보인다. Korean Patent Application No. 2012-0002573 discloses a method of cutting a corner in a strip form by moving a heated member in contact with a corner of a cooled glass substrate, as shown in FIG. 1. This method can prevent the glass dust generated during the polishing of the edge of the glass substrate inherently, and may be useful in this field.
그러나, 상기 방법은, 도 2에 도시된 바와 같이, 유리기판의 절단시 모서리에 칩핑(Chipping)이 발생한 경우(도2, (a)), 칩핑에 의해 모서리에 형성된 요철로 인하여 가열된 부재가 모서리에서 튕겨지는 현상이 발생하게 되며, 이에 의해 균일한 가공이 어려워지는 단점을 갖는다. 또한, 유리기판의 절단면에 포함된 변과 이웃하는 다른 변이 이루는 각이 90°에 근접하지 않는 경우에는 가열된 부재와 유리기판의 모서리가 닿는 부분과 닿지 않는 부분이 존재하게 되어(도2, (b)) 미절취 구간이 발생하게 되거나, 튀어나온 모서리 부분이 가열된 부재와 너무 강하게 닿게 되어 파손되는 부분이 발생하게 되는 단점을 갖는다. However, the method, as shown in Figure 2, when chipping (Chipping) occurs in the corners when cutting the glass substrate (Fig. 2, (a)), the heated member due to the irregularities formed in the corners by the chipping The phenomenon is caused to bounce off the corners, thereby making it difficult to uniformly process. In addition, when the angle formed by the edge included in the cut surface of the glass substrate and other neighboring edges does not approach 90 °, there is a part that does not touch the part where the edge of the heated member and the glass substrate touches (Fig. 2, ( b)) the uncut section may be generated or the protruding edge portion may come into contact with the heated member so strongly that a broken portion may occur.
또한, 도 3에 도시된 바와 같이, 유리기판의 두께에 편차가 존재하는경우에도 미절취 구간이 발생하게 되는 문제를 야기한다. In addition, as shown in Figure 3, even if there is a deviation in the thickness of the glass substrate causes a problem that the uncut section occurs.
본 발명은 종래기술의 상기와 같은 문제를 해결하기 위하여 안출된 것으로서, The present invention has been made to solve the above problems of the prior art,
유리기판 절단시 모서리에 칩핑이 발생하여 요철이 형성된 경우에도 모서리를 균일하게 절취하는 것이 가능하며,When cutting glass substrates, it is possible to evenly cut edges even when irregularities are formed due to chipping at the edges.
유리기판의 절단면이 정확한 각도(90 )로 절단되지 않은 경우에도 모서리의 균일한 절취가 가능하며,Even if the cut surface of the glass substrate is not cut at the correct angle (90), even cutting of the edge is possible.
유리기판의 두께에 편차가 존재하는 경우에도 미절취 구간이 발생하지 않게 모서리를 절취하는 것이 가능한 유리기판의 모서리 가공장치 및 그를 이용한 가공방법을 제공하는 것을 목적으로 한다. It is an object of the present invention to provide an edge processing apparatus for a glass substrate and a processing method using the same, which can cut corners so that an uncut section does not occur even if there is a deviation in the thickness of the glass substrate.

상기 가열부재유닛과 가열부재유닛 지지대는 압력부재에 의하여 연결되며, 상기 압력부재는 가열부재유닛의 측면에 2개 이상이 구비되며, 개수에 따라 가열부재유닛의 수직방향 중심축을 기준으로 힘의 합이 0이 되는 가열부재유닛의 측면 지점에 각각 일단부가 고정되고, 타단부는 상기 중심축과 상기 압력부재의 일단부가 고정된 가열부재유닛 측면의 동일선상의 외곽에 위치하는 가열부재유닛 지지대에 고정되며,The heating member unit and the heating member unit support are connected by a pressure member, the pressure member is provided with two or more on the side of the heating member unit, the sum of the forces based on the vertical central axis of the heating member unit according to the number One end is fixed to each side point of the heating member unit which becomes 0, and the other end is fixed to the heating member unit support which is located on the same line of the heating member unit side to which the central axis and one end of the pressure member are fixed. ,
상기 가열부재유닛은 가열된 상태에서 냉각된 유리기판의 절단부에 접촉되도록 가압되고, 상기 압력부재는 상기 가압에 의해 유발되는 압력에 대한 반작용으로 가열부재유닛을 바로 세우는 방향으로 압력을 유발시키는 수단인 것을 특징으로 하는 유리기판의 모서리 가공장치에 관한 것이다. The heating member unit is pressurized to be in contact with the cut portion of the cooled glass substrate in a heated state, and the pressure member is a means for inducing the pressure in the direction of straightening the heating member unit in response to the pressure caused by the pressing. The present invention relates to an edge processing apparatus for a glass substrate.
상기 유리기판의 모서리 가공장치는 유리기판의 모서리에 가열된 가열부재유닛을 접촉시킬 경우, 유리내부의 온도차에 의하여 상기 접촉부에서 스트립이 절취되므로 유리분말의 발생 없이 모서리를 균일하게 가공할 수 있다. When the edge processing apparatus of the glass substrate contacts the heated heating member unit at the edge of the glass substrate, the strip is cut at the contact portion due to the temperature difference inside the glass so that the edge may be uniformly processed without the generation of glass powder.
상기 가열부재유닛은 가열부재 자체를 의미하거나, 도 4에 도시된 바와 같이, 가열부재와 상기 가열부재를 가열부재유닛 지지대와 연결시키기 위한 수단으로서 가열부재의 외주에 결합되는 헤드부로 구성된 유닛을 의미한다. 상기 압력부재는 직접 가열부재에 결합될 수도 있지만, 가열부재가 고온으로 가열되므로 압력부재의 소재에 따라서는 가열부재에 직접결합하는 것이 바람직하지 않을 수도 있다. 따라서, 이러한 경우에는 도 4에 도시된 바와 같이, 헤드부를 매개하여 압력부재를 가열부재에 연결시키는 것이 바람직할 수 있다. The heating member unit means the heating member itself, or as shown in Figure 4, means a unit consisting of a head portion coupled to the outer periphery of the heating member as a means for connecting the heating member and the heating member with the heating member unit support. do. The pressure member may be directly coupled to the heating member, but since the heating member is heated to a high temperature, it may not be desirable to directly couple the heating member depending on the material of the pressure member. Therefore, in this case, as shown in Figure 4, it may be desirable to connect the pressure member to the heating member via the head portion.
상기 가열부재유닛은 유리기판 모서리와 접촉되는 부분이 외주면에서 중심축을 향하여 테이퍼진 형상을 가질 수 있다. 상기 외주면에서 중심부를 향하여 테이퍼진 형상은, 특별히 한정되는 것은 아니지만, 원뿔과 유사한 형태를 예로 들 수 있다.The heating member unit may have a tapered shape toward the central axis of the portion in contact with the edge of the glass substrate toward the outer peripheral surface. The shape tapered from the outer circumferential surface toward the center is not particularly limited, but examples thereof include a cone-like form.
상기와 같이 테이퍼진 형상을 가질 경우, 유리기판 모서리와의 접촉 및 코너링에 유리할 수 있다. In the case of having a tapered shape as described above, it may be advantageous for contacting and cornering the edge of the glass substrate.
상기 테이퍼진 부분의 윗부분은 특별히 한정되는 것은 아니지만 원통형의 형상일 수 있다. The upper portion of the tapered portion is not particularly limited but may have a cylindrical shape.
상기 가열부재는 이 분야에서 통상적으로 사용되는 수단에 의해서 가열될 수 있다. 예컨대, 전기저항방식, 고주파유도가열방식 등이 사용될 수 있다. 상기 고주파유도가열방식은 고주파 전류가 흐르는 코일의 중간에 위치한 가열부재가 전자 유도 작용으로 일어나는 와전류(EDDYCURRENT)및 일부의 HYSTERESIS의 열손실에 의해서 급속히 가열되는 방식에 의해 가열되는 방식의 의미한다. The heating member may be heated by means commonly used in the art. For example, an electric resistance method, a high frequency induction heating method, or the like can be used. The high frequency induction heating method refers to a method in which a heating member located in the middle of a coil in which a high frequency current flows is heated by a method of heating rapidly by the eddy current EDDYCURRENT generated by the electromagnetic induction action and the heat loss of some HYSTERESIS.
상기 고주파유도가열방식은 코일을 관통하는 가열부재에 에너지를 효과적으로 집중시킬 수 있어, 빠른 온도 상승이 가능하고 냉각 부재와의 접촉에 의한 가열부재의 온도저하를 방지하는데 특히 유리하므로, 본 발명에서 바람직하게 사용될 수 있다.The high frequency induction heating method can effectively concentrate energy on the heating member penetrating the coil, so that it is possible to increase the temperature quickly and is particularly advantageous in preventing the temperature drop of the heating member due to contact with the cooling member. Can be used.
본 발명에 있어서, 상기 가열부재의 가열 온도는 유리의 Tg 이상으로 상승되는 것을 의미한다. 유리의 Tg는 유리의 종류에 따라 750℃에서 1300℃까지 다양하다. 본 발명의 실시에 있어서, 가열부재의 온도는 가공부의 적절한 절취를 위해서, 유리의 Tg 보다 50℃이상, 바람직하게는 100℃ 이상, 보다 더 바람직하게는 200-500 ℃ 정도 높게 유지되는 것이 바람직하다.In the present invention, it means that the heating temperature of the heating member is raised above the Tg of the glass. Tg of glass varies from 750 degreeC to 1300 degreeC according to the kind of glass. In the practice of the present invention, the temperature of the heating element is preferably maintained at 50 ° C or higher, preferably 100 ° C or higher, even more preferably 200-500 ° C or higher than the Tg of the glass in order to appropriately cut the processed portion. .
상기 압력부재는 스프링, 같은 극의 척력을 이용하는 한 쌍의 자석, 벨로스 같이 공기의 압축과 그에 따른 반작용을 이용하는 수단일 수 있다. The pressure member may be a spring, a pair of magnets using the same repulsive force, a means of using the compression of air and the resulting reaction, such as bellows.
상기 압력부재가 2개로 이루어지는 경우, 도 4에 도시된 바와 같이,가열부재유닛 측면 중, 가열부재유닛의 수직방향 중심축을 기준으로 서로 마주보는 지점에 각각 일단부가 고정되고, 타단부는가열부재유닛지지대에고정될수있다. When the pressure member is composed of two, as shown in Figure 4, one end is fixed to each of the points facing each other on the basis of the central axis in the vertical direction of the heating member unit, the other end of the heating member unit Can be fixed to the support
상기 가열부재유닛 지지대는 상기 중심축과 상기 압력부재의 일단부가 고정된 가열부재유닛 측면의 동일선상의 외곽에 위치할 수 있다.The heating member unit support may be located on the same line of the side of the heating member unit side fixed to the central axis and one end of the pressure member.
상기 가열부재유닛 지지대는 압력부재를 매개하여 가열부재유닛을 고정할 수 있는 구조를 갖는 것이라면 그 형태는 특별히 한정되지 않으며, 이 분야에서 공지된 형태가 사용될 수 있다. The heating member unit support is not particularly limited as long as it has a structure capable of fixing the heating member unit via a pressure member, a form known in the art can be used.
상기 유리기판 지지대는 유리기판을 고정할 수 있는 구성요소로서, 이 분야에서 공지된 다양한 형태의 고정수단을 구비할 수 있다. 특히, 유리기판 지지대는 유리기판을 냉각시키기 위한 냉각수단을 더 구비할 수 있다. 상기 냉각수단은 예컨대, 저온의 냉매가 흐르는 관로가 형성되어 있는 냉각판이 지지대 바닥에 형성된 것일 수 있다. The glass substrate support is a component capable of fixing the glass substrate, and may be provided with various forms of fixing means known in the art. In particular, the glass substrate support may further include cooling means for cooling the glass substrate. The cooling means may be, for example, a cooling plate formed with a pipe through which a low temperature refrigerant flows is formed at the bottom of the support.
본 발명의 유리기판 절단부의 가공장치에 있어서, 가열부재유닛이 유리의 Tg 이상으로 가열되므로, 유리기판의 온도가 0~50℃인 상태에서도 유리내부의 온도차이에 의해서 스트립의 절취가 가능하다. In the processing apparatus of the glass substrate cutout part of the present invention, since the heating member unit is heated to Tg or more of the glass, the strip can be cut by the temperature difference inside the glass even when the temperature of the glass substrate is 0 to 50 ° C.
그러나, 스트립 절취의 효과를 높이기 위해서 유리기판을 냉각시키는 것도 가능하다. 상기 "냉각"은 강제적인 방식에 의해서 유리기판의 온도가 주변부보다 낮은 상태로 하는 것을 의미한다.However, it is also possible to cool the glass substrate in order to increase the effect of strip cutting. "Cooling" means that the temperature of the glass substrate is lower than the peripheral portion by a forced method.
상기 냉각은 유리기판을 전체적으로 냉각시키거나, 유리기판의 가공부만을 선별적으로 냉각시키는 것도 가능하지만, 안정적인 제어를 위해서 유리기판 전체를 냉각하는 것이 바람직하다.The cooling may cool the glass substrate as a whole or selectively cool only the processed portion of the glass substrate, but it is preferable to cool the entire glass substrate for stable control.
상기 유리기판의 냉각은 저온으로 유지되는 작업 환경에 유리기판을 일정시간 적치하여 이루어질 수 있으며, 또한 저온으로 유지되는 냉각 판에 유리기판을 접촉시킴으로써 이루어질 수도 있다. 바람직하게는 작업 중 유리의 온도가 상승하는 것을 피할 수 있도록 일정온도로 유지되는 냉각 판에 고정한 상태로 절취 작업이 이루어지는 것이 좋다.Cooling of the glass substrate may be performed by placing a glass substrate in a working environment maintained at a low temperature for a predetermined time, or by contacting the glass substrate to a cooling plate maintained at a low temperature. Preferably, the cutting operation is performed in a state of being fixed to a cooling plate maintained at a constant temperature so as to avoid an increase in the temperature of the glass during the operation.
본 발명에서 유리기판의 냉각 온도는 상온(=25 ℃)보다 낮은 온도, 보다 바람직하게는 가열부재유닛과 접촉된 유리기판이 분진 없이 절단되어 분리될 수 있도록 상온보다 10℃이상 낮은 온도로 냉각되는 것이 좋다. 본 발명의 실시에 있어서, 상기 유리기판의 온도는 10℃ 이하가 바람직하며, 과다한 냉각에 소비되는 에너지를 줄일 수 있도록 0~10℃ 범위가 더욱 바람직하다. In the present invention, the cooling temperature of the glass substrate is cooled to a temperature lower than room temperature (= 25 ℃), more preferably at least 10 ℃ lower than the normal temperature so that the glass substrate in contact with the heating member unit can be separated by cutting without dust. It is good. In the practice of the present invention, the temperature of the glass substrate is preferably 10 ℃ or less, more preferably in the range 0 ~ 10 ℃ to reduce the energy consumed for excessive cooling.
상기 유리기판의 온도가 높을 경우에는 모서리로부터 절취되는 양이 많아져 박판 유리에 대한 정밀한 모서리 절취가 어려워지며, 상기 유리기판의 온도가 지나치게 낮을 경우 과다한 에너지 소비를 유발하게 되며 일정 공정 제어가 어려워질 수 있다.When the temperature of the glass substrate is high, the amount of cutting from the edges increases, making it difficult to precisely cut edges of the thin glass. When the temperature of the glass substrate is too low, excessive energy consumption is caused and it becomes difficult to control a certain process. Can be.
본 발명에 있어서, 상기 가열부재유닛과 유리기판은 상대적으로 이동할 수 있다. 즉, 가열부재유닛이 이동하거나, 유리기판이 이동하거나, 유리 기판과 가열부재유닛이 동시에 이동하는 것일 수도 있다. 상기 가열부재유닛 및 유리기판의 이동은 각각 가열부재유닛 지지대 및 유리기판 지지대의 작동에 의해서 이루어질 수 있다. In the present invention, the heating member unit and the glass substrate can be relatively moved. That is, the heating member unit may move, the glass substrate may move, or the glass substrate and the heating member unit may move simultaneously. Movement of the heating member unit and the glass substrate may be made by operation of the heating member unit support and the glass substrate support, respectively.
상기 가열부재유닛 및/또는 유리기판의 이동 속도는 생산성, 절취 깊이, 온도차, 및 압력차를 고려해서 조절될 수 있다.The moving speed of the heating member unit and / or the glass substrate may be adjusted in consideration of productivity, cutting depth, temperature difference, and pressure difference.
본 발명에 있어서, 상기 가열부재유닛 지지대 및 유리기판 지지대는 둘 중 하나는 고정되고, 나머지 하나는 가열부재와 유리기판 절단부의 가공부가 접촉을 유지하면서 이동할 수 있도록 설치될 수 있다. 바람직하게는 가열부재유닛 지지대가 고정되고 유리기판 지지대가 이동을 하는 것이 좋다. 왜냐하면, 가열부재유닛 지지대가 움직일 경우 움직임에 의한 대류 현상으로 인하여 가열부에 온도 변화가 발생하여 균일한 스트립의 절취가 어렵기 때문이다. In the present invention, one of the heating member unit support and the glass substrate support is fixed, the other one may be installed so as to move while maintaining the processing portion of the heating member and the glass substrate cut. Preferably, the heating member unit support is fixed and the glass substrate support is preferably moved. This is because, when the heating member unit support moves, a temperature change occurs in the heating part due to the convection phenomenon caused by the movement, which makes it difficult to cut the uniform strip.
본 발명에 있어서, 가열부재유닛과 유리기판 모서리의 접촉은 가열부재유닛에 0.1-3.0 Kgf/㎠, 보다 바람직하게는 0.5-1.5 Kgf/㎠정도의 압력이 가해지도록 가압되는 것에 의하여 이루어지는 것이 바람직하다. 압력이 지나치게 높을 경우 절취되는 양이 많아져 박판 유리의 모서리 가공에는 적합하지 않을 수 있으며, 압력이 지나치게 낮을 경우 모서리에 요철이 형성되거나, 모서리가 정확한 각도로 절단되지 않은 경우에 모서리를 균일하게 절취할 수 없다. 즉, 본 발명의 모서리 가공장치는 모서리에 요철이 형성된 경우라 하더라도, 상기 가열부재유닛에 가해지는 압력 및 압력부재의 가열부재유닛에 발생하는 변이 수용능력에 의해 가열부재유닛이 요철의 굴곡을 따라 이동하게 되므로 모서리의 균일한 절취가 가능하게 된다. In the present invention, the contact between the heating member unit and the edge of the glass substrate is preferably made by being pressed to apply a pressure of about 0.1-3.0 Kgf / cm 2, more preferably about 0.5-1.5 Kgf / cm 2. . If the pressure is too high, the amount of cut may increase, which may not be suitable for processing edges of thin glass. If the pressure is too low, irregularities are formed in the edges, or even edges are cut evenly if the edges are not cut at the correct angle. Can not. That is, in the corner processing apparatus of the present invention, even when irregularities are formed in the corners, the heating member unit is formed by the pressure applied to the heating member unit and the displacement capacity generated in the heating member unit of the pressure member along the curvature of the irregularities. Since it moves, even cutting of the edges is possible.
또한, 유리기판의 모서리가 정확한 각도로 절단되지 않거나, 유리기판의 두께가 일정하지 않은 경우에도 상기와 같은 메커니즘에 의해 모서리의 균일한 절취가 가능해진다. In addition, even when the edges of the glass substrate are not cut at the correct angle or the thickness of the glass substrate is not constant, even cutting of the edges is possible by the above mechanism.
본 발명에 있어서, 상기 유리기판의 모서리를 가공하는 경우, 특별히한정되는 것은 아니나, 수평면과 수직면이 교차되는 모서리에서 수평면과 수직면을 따라 50 ㎛-5 mm의 범위로 절취될 수 있다. 절취되는 모서리는 스트립 형태로 절취되어 유리 분진이나 유리 조각에 의한 2차 피해를 방지할 수 있다. In the present invention, when processing the edge of the glass substrate is not particularly limited, but may be cut in the range of 50 ㎛-5 mm along the horizontal plane and the vertical plane at the corner where the horizontal plane and the vertical plane intersect. The cut edges may be cut into strips to prevent secondary damage by glass dust or glass chips.
