유리기판 성형장치Glass Substrate Forming Equipment
본 발명은 유리기판 성형장치에 관한 것으로서 더욱 상세하게는 유리기판을 3차원 형상으로 성형 시 평면을 이루게 될 일 영역과 곡면을 갖게 될 가장자리 영역인 타 영역을 순차적으로 성형함으로써, 품질이나 외관 불량을 최소화하면서 유리기판을 성형할 수 있는 유리기판 성형장치에 관한 것이다.The present invention relates to an apparatus for forming a glass substrate, and more particularly, by forming a glass substrate in a three-dimensional shape, by sequentially molding one region to form a plane and another region, which is an edge region to have a curved surface, to reduce quality or appearance defects. The present invention relates to a glass substrate molding apparatus capable of molding a glass substrate while minimizing it.
IT 및 디스플레이용 3차원 형상의 유리 제품 성형을 위해, 현재 크게 세 가지 정도의 방법이 이용되고 있다. 하지만, 현재 이용되고 있는 각각의 방법들은 그 특징에 따른 제약 사항을 안고 있다.Three types of methods are currently used for shaping three-dimensional glass products for IT and displays. However, each of the methods currently in use has its limitations.
예를 들어, 진공압을 이용한 3차원 형상 성형 방법은 진공압을 이용함으로 인해, 형상이 복잡하거나 형상 변화가 좁은 범위에서 급격하게 일어나는 제품 디자인은 그 형상을 구현하는데 한계가 있다. 또한, 상, 하 2개의 금형을 이용하는 성형 방법은 진공 성형 방법에 비해 다소 복잡한 형상의 구현이 가능하나, 상, 하 2개의 금형이 세트로 구성되어 있어, 금형 내부에 위치되는 유리기판의 온도를 성형 가능한 수준까지 올리는데 긴 사이클 타임(cycle time)이 필요하며, 특히, 비대칭적 형상 구조를 가지는 제품 디자인은 유리기판의 로딩 및 성형이 매우 어려워, 형상 구현이 어려운 한계가 있다. 그리고 프레스(press)를 이용한 성형 방법은 상기 2개의 성형 방법에 비해, 형상 구현이나 사이클 타임 측면에서 유리한 방법이나 성형 구간의 고온 환경 하에서 상, 하부 금형의 얼라인먼트(alignment)를 정교하게 유지하는데 한계가 있으며, 얼라인먼트가 조금이라도 벗어나게 되면, 제품 표면에 긁힘(scuff) 등의 불량이 유발되거나, 치수 품질 편차가 유발될 수 있다.For example, in the three-dimensional shape forming method using vacuum pressure, due to the use of vacuum pressure, a product design that occurs rapidly in a complicated shape or a narrow shape change has a limitation in implementing the shape. In addition, the molding method using two upper and lower molds can implement a somewhat more complicated shape than the vacuum molding method, but the upper and lower molds are composed of a set, and thus the temperature of the glass substrate placed inside the mold can be adjusted. It takes a long cycle time to raise to the moldable level, and in particular, the product design having an asymmetrical shape structure is very difficult to load and form a glass substrate, there is a limit that the shape implementation is difficult. In addition, the molding method using a press has a limit in maintaining alignment of upper and lower molds precisely in a high temperature environment of a molding section or an advantageous method in terms of shape implementation or cycle time, compared to the two molding methods. If the alignment is slightly out of order, a defect such as a scuff or the like on the surface of the product may be caused, or a dimensional quality deviation may be caused.

Or it is an apparatus for shaping more sides into a curved surface. The glass substrate molding apparatus 100 is formed to include a molding furnace 110, the upper mold 120 and the lower mold 130.

성형로(110)는 성형될 유리기판(G)을 성형 가능 온도까지 가열하는 장치이다. 또한, 성형로(110)는 유리기판(G)의 성형 공정이 이루어지는 장소를 제공한다. 이에 따라, 성형로(110)의 일측과 타측에는 유리기판(G)의 인입 및 인출을 위한 인입구(미도시)와 인출구(미도시)가 각각 형성된다. 또한, 성형로(110) 내부에는 상부 금형(120) 및 하부 금형(130)이 배치된다. 이때, 도시한 바와 같이, 본 발명의 일 실시 예에서는 인-라인(in-line) 방식으로 유리기판(G)을 성형하므로, 성형로(110)의 바닥면에는 다수의 하부 금형(130) 이송을 위한 컨베이어 벨트(111)가 설치된다. 하지만, 이는 일례일 뿐, 성형 공정은 로터리(rotary) 방식이나 배치(batch) 방식으로도 이루어질 수 있다.The molding furnace 110 is a device for heating the glass substrate G to be molded to a moldable temperature. In addition, the forming furnace 110 provides a place where the forming process of the glass substrate (G) is made. Accordingly, an inlet (not shown) and an outlet (not shown) are formed at one side and the other side of the molding furnace 110 for the inlet and outlet of the glass substrate G, respectively. In addition, the upper mold 120 and the lower mold 130 are disposed in the molding furnace 110. At this time, as shown, in one embodiment of the present invention, because the glass substrate (G) is molded in an in-line (in-line) method, a plurality of lower mold 130 is transferred to the bottom surface of the molding furnace 110 Conveyor belt 111 for is installed. However, this is merely an example, and the molding process may be performed in a rotary or batch manner.
또한, 성형로(110) 내부에는 컨베이어 벨트(111)를 타고 이송되는 하부 금형(130)에 탑재되어 있는 유리기판(G)을 성형 가능 온도로 가열하기 위한 발열체와 같은 가열장치(112)가 하부 금형(130)의 이송 방향을 따라 설치된다. 그리고 도시한 바와 같이, 본 발명의 일 실시 예에서는 상부 금형(120)만 성형로(110) 내부에 고정 설치되고, 하부 금형(130)은 컨베이어 벨트(111)를 타고 성형로(110) 내부를 이동 가능하게 형성된다.In addition, inside the molding furnace 110, a heating device 112 such as a heating element for heating the glass substrate G mounted on the lower mold 130 transported on the conveyor belt 111 to a moldable temperature is provided in the lower portion. It is installed along the conveying direction of the mold 130. And, as shown, in one embodiment of the present invention, only the upper mold 120 is fixedly installed in the molding furnace 110, the lower mold 130 is a conveyor belt 111 to ride the inside of the molding furnace 110 It is formed to be movable.

도 2 내지 도 4에 도시한 바와 같이, 본 발명의 일 실시 예에 따른 상부 금형(120)은 성형로(110) 내부에 장착되어, 유리기판(G)을 탑재한 채 컨베이어 벨트(111)에 의해 이송되는 하부 금형(130)이 하측에 얼라인된 경우, 하부 금형(130)과 함께 평판형의 유리기판(G)을 3차원, 즉, 유리기판(G)의 4변 중 적어도 어느 하나의 변이 곡면을 이루도록 성형시킨다. 본 발명의 일 실시 예에 따른 상부 금형(120)은 2개의 분할된 구조로 이루어진다. 즉, 본 발명의 일 실시 예에서, 상부 금형(120)은 코어부(121) 및 사이드부(122)를 포함하여 형성된다.2 to 4, the upper mold 120 according to an embodiment of the present invention is mounted in the molding furnace 110, on the conveyor belt 111 with the glass substrate (G) mounted. When the lower mold 130 to be transferred is aligned at the lower side, the plate-shaped glass substrate G together with the lower mold 130 is three-dimensional, that is, at least one of four sides of the glass substrate G. The sides are molded to form a curved surface. Upper mold 120 according to an embodiment of the present invention is composed of two divided structures. That is, in one embodiment of the present invention, the upper mold 120 is formed including the core portion 121 and the side portion 122.
여기서, 코어부(121)는 성형로(110) 내부에 승강 가능하게 장착되어 있다. 이에 따라, 하측에 하부 금형(130)이 얼라인된 경우, 하강하여 유리기판(G)의 일 영역, 즉, 성형 후 평면을 이루게 되는 유리기판(G)의 중심 영역을 가압한다. 그리고 성형 완료 후 성형로(110)의 천장 쪽으로 상승하여, 성형된 유리기판(G)이 탑재된 하부 금형(130)이 컨베이어 벨트(111)를 통해 성형로(110)의 인출구(미도시) 측으로 이송되도록 하고, 성형될 유리기판(G)이 탑재된 다른 하부 금형(130)이 컨베이어 벨트(111)를 통해 상부 금형(120) 하측에 얼라인되도록 한다.Here, the core portion 121 is mounted to the inside of the molding furnace 110 to be elevated. Accordingly, when the lower mold 130 is aligned on the lower side, the lower mold 130 is lowered to press one region of the glass substrate G, that is, the center region of the glass substrate G to form a flat surface after molding. After the molding is completed, the mold is raised toward the ceiling of the molding furnace 110, and the lower mold 130 on which the molded glass substrate G is mounted is moved to the outlet (not shown) of the molding furnace 110 through the conveyor belt 111. The lower mold 130 on which the glass substrate G to be molded is mounted is aligned with the upper mold 120 under the conveyor belt 111.
또한, 사이드부(122)는 코어부(121)의 측부에 위치된다. 상부 금형은 초기 상태로부터 제1단계 하강 및 제2단계 하강을 수행한다. 초기 상태에서, 사이드부는 코어부보다 높은 위치에 위치된다. 제1단계 하강에서는, 사이드부(122)는 코어부(121)의 승강 운동에 종속되어 함께 승강된다. 하지만, 제2단계 하강에서는, 사이드부(122)는 코어부(121)의 측부에서 독립적으로 승강 가능하다. 이에 따라, 상부 금형(120)은 코어부(121)에 의한 1단계 하강과 사이드부(122)에 의한 2단계 하강으로 동작하게 된다. 사이드부(122)는 코어부(121)에 상대 승강 이동 가능하게 결합될 수 있다. 이러한 사이드부(122)는 코어부(121)에 의해 가압되는 유리기판(G)의 중심 영역 이외의 타 영역 즉, 유리기판(G)의 가장자리 영역의 일부 또는 전부를 가압한다. 이때, 도시한 바와 같이, 사이드부(122)는 코어부(121)가 하강하여 유리기판(G)의 중심 영역에 밀착되고 이를 가압한 후, 하강하여 가장자리 영역을 가압한다. 즉, 평판형의 유리기판(G)은 사이드부(122)에 의해 4변 중 적어도 한 변이 곡면을 이루는 3차원 형상으로 성형된다.In addition, the side portion 122 is located at the side of the core portion 121. The upper mold performs the first step descending and the second step descending from the initial state. In the initial state, the side portion is located at a position higher than the core portion. In the first step descending, the side part 122 is lifted together depending on the lifting motion of the core part 121. However, in the second step descending, the side part 122 can be independently lifted on the side of the core part 121. Accordingly, the upper mold 120 is operated by one step descending by the core part 121 and two step descending by the side part 122. The side part 122 may be coupled to the core part 121 so as to be movable relative to each other. The side part 122 presses a part or all of other areas other than the center area of the glass substrate G pressed by the core part 121, that is, the edge area of the glass substrate G. At this time, as shown in the drawing, the side part 122 descends the core part 121 to be in close contact with the center area of the glass substrate G and presses it, and then descends to press the edge area. That is, the flat glass substrate G is molded into a three-dimensional shape in which at least one of four sides forms a curved surface by the side portion 122.
여기서, 성형되는 유리기판(G)은 탄성 변형되므로, 코어부(121)와 사이드부(122)의 전체 가압 면적이 유리기판(G)과 같을 필요는 없다. 또한, 코어부(121) 및 사이드부(122)의 가압면의 형상이 성형될 유리기판(G)의 형상과 동일할 필요 또한 없다. 때문에, 사이드부(122)는 코어부(121)의 측부에 밀착되는 형태로 형성되거나 이격되는 형태로도 형성될 수 있고, 사이드부(122)의 가압면은 하기에서 설명될 하부 금형(130)의 성형부(131)의 벽면과 동일 곡률로만 형성되면 된다.Here, since the glass substrate G to be molded is elastically deformed, the entire pressurized areas of the core portion 121 and the side portion 122 need not be the same as the glass substrate G. In addition, the shape of the pressing surfaces of the core portion 121 and the side portion 122 need not be the same as the shape of the glass substrate G to be molded. Therefore, the side portion 122 may be formed in a form that is in close contact with the side portion of the core portion 121, or may be formed in a form that is spaced apart, the pressing surface of the side portion 122 will be described below the lower mold 130 It has to be formed only with the same curvature as the wall surface of the shaping part 131 of FIG.

도 2 내지 도 4에 도시한 바와 같이, 본 발명의 일 실시 예에 따른 하부 금형(130)은 유리기판(G)이 탑재되는 일면에 성형부(131)가 형성되어 있다. 이러한 하부 금형(130)은 상부 금형(120)에 의한 유리기판(G) 가압 시 성형부(131)의 형상을 따라 변형되는 유리기판(G)을 지지한다. 본 발명의 일 실시 예에서, 성형부(131)는 음각 구조로 이루어진다. 즉, 성형부(131)는 홈 형태로 형성되는데, 코어부(121) 및 사이드부(122) 하강 시 코어부(121) 및 사이드부(122)를 내측에 수용 가능한 크기의 홈으로 형성된다. 이때, 평판형의 유리기판(G)은 상부 금형(120)에 의해 가압되어, 하부 금형(130)의 성형부(131) 형상을 따라 변형되어, 3차원 형상을 갖게 되므로, 성형부(131)의 적어도 한 벽면은 곡면으로 형성되는데, 이 곡면의 곡률은 사이드부(122)의 가압면의 곡률과 동일할 수 있다.2 to 4, in the lower mold 130 according to the exemplary embodiment of the present invention, a molding part 131 is formed on one surface on which the glass substrate G is mounted. The lower mold 130 supports the glass substrate G that is deformed along the shape of the molding part 131 when the glass substrate G is pressed by the upper mold 120. In one embodiment of the present invention, the molding unit 131 is formed of a negative structure. That is, the molding part 131 is formed in the shape of a groove, and when the core part 121 and the side part 122 descend, the core part 121 and the side part 122 are formed into grooves having a size that can accommodate the inside. At this time, the plate-shaped glass substrate (G) is pressed by the upper mold 120, is deformed along the shape of the molding portion 131 of the lower mold 130, and has a three-dimensional shape, the molding portion 131 At least one wall surface of the is formed of a curved surface, the curvature of the curved surface may be the same as the curvature of the pressing surface of the side portion (122).
여기서, 유리기판(G)의 2변에 곡면을 주고자 하는 경우, 사이드부(122)는 코어부(121) 양측에 2개 장착되고, 성형부(131)도 이와 대응되는 2개의 벽면이 곡면으로 형성된다. 즉, 사이드부(122)의 형성 개수 및 성형부(131)의 곡면 벽면 수는 곡면으로 형성하고자 하는 유리기판(G) 변의 수에 따라 결정된다.In this case, in order to give a curved surface to two sides of the glass substrate G, two side parts 122 are mounted on both sides of the core part 121, and two wall surfaces corresponding to the molding part 131 also have curved surfaces. Is formed. That is, the number of side portions 122 formed and the number of curved wall surfaces of the molded portion 131 are determined according to the number of sides of the glass substrate G to be formed into a curved surface.

이하, 본 발명의 일 실시 예에 따른 유리기판 성형장치의 작용에 대해 설명하기로 한다.Hereinafter, the operation of the glass substrate forming apparatus according to an embodiment of the present invention will be described.
먼저, 성형부(131) 상에 유리기판(G)을 탑재한 하부 금형(130)이 성형로(110)의 인입구(미도시)를 통해 성형로(110) 내부로 인입되면, 컨베이어 벨트(111)가 작동되어 하부 금형(130)을 상부 금형(120)이 설치되어 있는 쪽으로 이송시킨다. 이때, 가열장치(112)는 하부 금형(130)에 탑재된 유리기판(G)이 상부 금형(120)에 도달되기 전까지 유리기판(G)을 성형 가능 온도로 가열한다. 그 다음, 하부 금형(130)이 상부 금형(120) 하측에 위치되면, 컨베이어 벨트(111)는 작동을 멈추고, 하부 금형(130)이 상부 금형(120) 하측에 얼라인되도록 한다. 그 다음 유리기판(G)을 성형하기 위해, 상부 금형(120)의 코어부(121)가 하강하여 유리기판(G)의 중심 영역을 가압한다. 그 다음, 상부 금형(120)의 사이드부(122)가 하강하여 성형부(131)의 형상을 따라 유리기판(G)의 가장자리 영역이 변형되도록 유리기판(G)의 가장자리 영역을 가압한다.First, when the lower mold 130 on which the glass substrate G is mounted on the molding part 131 is introduced into the molding furnace 110 through an inlet (not shown) of the molding furnace 110, the conveyor belt 111 may be used. ) Is operated to transfer the lower mold 130 toward the upper mold 120. In this case, the heating apparatus 112 heats the glass substrate G to a moldable temperature until the glass substrate G mounted on the lower mold 130 reaches the upper mold 120. Then, when the lower mold 130 is positioned below the upper mold 120, the conveyor belt 111 stops operation and causes the lower mold 130 to be aligned below the upper mold 120. Then, in order to mold the glass substrate G, the core portion 121 of the upper mold 120 is lowered to press the central region of the glass substrate G. Next, the side portion 122 of the upper mold 120 is lowered to press the edge region of the glass substrate G so that the edge region of the glass substrate G is deformed along the shape of the molding portion 131.
이와 같이, 영역별 순차적인 가압 방식으로 이루어지는 유리기판(G)에 대한 성형 완료 후, 상부 금형(120)과 하부 금형(130)이 서로 이격되도록, 하강 반대 순으로, 사이드부(122)가 상승한 다음 코어부(121)가 상승한다. 그 다음, 다시 컨베이어 벨트(111)가 작동하여 성형 완료된 유리기판(G)을 탑재한 하부 금형(130)을 성형로(110)의 인출구(미도시) 측으로 이동시키고, 성형될 유리기판(G)을 탑재한 다른 하부 금형(130)을 상부 금형(120) 하측에 위치시킨다. 즉, 본 발명의 일 실시 예에 따른 유리기판 성형장치(100)는 인-라인 방식으로 다수의 유리기판(G)을 연속적으로 3차원 형상으로 성형한다.As such, after completion of the molding of the glass substrate G formed by the sequential pressing method for each region, the side portions 122 are raised in the opposite order of descending so that the upper mold 120 and the lower mold 130 are spaced apart from each other. The core portion 121 then rises. Then, the conveyor belt 111 is operated again to move the lower mold 130 on which the molded glass substrate G is mounted to the outlet (not shown) side of the molding furnace 110, and the glass substrate G to be molded. Another lower mold 130, which is mounted thereon, is positioned below the upper mold 120. That is, the glass substrate molding apparatus 100 according to an embodiment of the present invention continuously molds the plurality of glass substrates G in a three-dimensional shape in an in-line manner.

상술한 바와 같이, 본 발명의 일 실시 예에 따른 유리기판 성형장치(100)는 성형 후 평면을 이루게 되는 유리기판(G)의 일 영역을 가압하는 코어부(121)와, 유리기판(G)의 가장자리 영역으로 성형 후 곡면을 갖는 타 영역을 가압하는 사이드부(122)로 분할된 구조를 갖는 상부 금형(120)을 구비한다. 이를 통해, 본 발명의 일 실시 예에 따른 유리기판 성형장치(100)는 유리기판(G)의 일 영역인 중심 영역과 가장자리 영역을 순차적으로 가압, 성형함으로써, 품질이나 외관 불량을 최소화하면서 유리기판(G)을 3차원 형상으로 성형할 수 있다.As described above, the glass substrate forming apparatus 100 according to an embodiment of the present invention is the core portion 121 for pressing a region of the glass substrate (G) to form a plane after molding, and the glass substrate (G) The upper mold 120 having a structure divided into a side portion 122 for pressing the other region having a curved surface after molding to the edge region of the.
