최근에는 화면이 오목한 곡면을 가짐으로써 화면 양끝의 영상이 매우 선명한 특징을 보이는 곡면 디스플레이 패널이 생산되고 있다.Recently, a curved display panel having a concave curved surface and displaying very sharp images at both ends of the screen has been produced.
곡면 디스플레이 패널을 제작하는 데에는 곡면 디스플레이의 화면 크기를 결정하고 화면 외곽을 보호하기 위한 곡면 프레임의 제작 또한 중요하다. 가장자리에 플랜지를 구비하는 곡면 프레임의 경우, 플랜지가 휘어지거나 울지 않고 일정한 곡률을 갖는 것이 제품 품질을 평가하는데 중요한 요인이 된다.In manufacturing a curved display panel, it is also important to determine the screen size of the curved display and to manufacture a curved frame for protecting the periphery of the screen. In the case of a curved frame having a flange at the edge, it is an important factor in evaluating product quality that the flange has a constant curvature without bending or crying.
또한, 판상의 프레임을 곡면 프레임으로 가공한 다음 바(bar) 형태의 플랜지를 곡면 프레임의 곡률에 맞게 절단한 후, 이를 곡면 프레임의 가장자리에 용접하여 접합할 수 있다. 하지만, 이러한 일련의 용접 공정을 통해서는 일정한 곡률을 갖는 플랜지를 형성하는데 어려움이 있었으며, 벤딩 공정 후 추가적인 용접 공정을 진행함에 따라, 제작 공정이 복합하고 제작 시간이 오래 소요되는 등의 품질 및 공정 상의 여러 문제가 있었다.In addition, after processing the plate-shaped frame into a curved frame, cutting a bar-shaped flange according to the curvature of the curved frame, it can be welded to the edge of the curved frame. However, it was difficult to form a flange with a constant curvature through this series of welding processes, and as an additional welding process was performed after the bending process, the manufacturing process was complex and took a long time to manufacture, resulting in quality and process problems. There were several problems.

도 18은 본 발명의 일 실시예에 따른 곡면 디스플레이용 곡면 프레임 벤딩장치에서 평면 프레임과 절곡라인 형성부를 개략적으로 도시한 평면도이다.18 is a plan view schematically illustrating a flat frame and a bending line forming unit in a curved frame bending device for a curved display according to an embodiment of the present invention.
도 18을 참조하면, 곡면 프레임 벤딩장치(100)는 평판 프레임(10a)의 양측에 플랜지부(12)가 절곡될 부분에 절곡라인부(11)를 형성하는 절곡라인 형성부(150)를 더 포함한다. 절곡라인 형성부(150)는 이송 롤러부(110)에 평판 프레임(10a)이 공급되는 위치에 설치될 수 있다. 절곡라인 형성부(150)로는 펀치부나 레이저 커팅기 등이 적용될 수 있다. Referring to FIG. 18, the curved frame bending device 100 further includes a bending line forming unit 150 for forming a bending line unit 11 at a portion where the flange unit 12 is to be bent on both sides of the flat frame 10a. include The bending line forming unit 150 may be installed at a position where the flat frame 10a is supplied to the conveying roller unit 110 . As the bending line forming unit 150, a punch unit or a laser cutting machine may be applied.

In addition, the bending line portion 11 may be formed in a straight groove shape or a dotted line groove shape so as not to penetrate the flat frame 10a. Since the bending line portions 11 are formed on both sides of the flat frame 10a before the flat frame 10a is supplied to the conveying roller unit 110, the flange portion 12 of the flat frame 10a is smoother and It can be bent easily.
상기와 같이 구성되는 본 발명의 일 실시예에 따른 곡면 디스플레이용 곡면 프레임의 제조방법에 관해 설명하기로 한다.A method of manufacturing a curved frame for a curved display according to an embodiment of the present invention configured as described above will be described.
도 19는 본 발명의 일 실시예에 따른 곡면 디스플레이용 곡면 프레임의 제조방법을 개략적으로 도시한 플로우차트이다.19 is a flowchart schematically illustrating a method of manufacturing a curved frame for a curved display according to an embodiment of the present invention.
도 19를 참조하면, 이송 롤러부(110)에 평판 프레임(10a)이 공급된다(S11). 평판 프레임(10a)은 사각틀 형태로 형성된다. 이때, 절곡라인부(11)가 양측에 형성되지 않은 평판 프레임(10a)이 이송 롤러부(110)에 공급될 수 있다. Referring to FIG. 19 , the flat frame 10a is supplied to the conveying roller unit 110 (S11). The flat frame 10a is formed in a rectangular frame shape. At this time, the flat frame 10a without the bending line part 11 formed on both sides may be supplied to the conveying roller part 110 .
이송 롤러부(110)에 평판 프레임(10a)이 공급기 이전에, 절곡라인 형성부(150)가 평판 프레임(10a)의 양측에 절곡라인부(11)를 형성할 수 있다. 따라서, 절곡라인부(11)가 양측에 형성된 평판 프레임(10a)이 이송 롤러부(110)에 공급될 수 있다.Before supplying the flat frame 10a to the transfer roller unit 110, the bending line forming unit 150 may form the bending line unit 11 on both sides of the flat frame 10a. Accordingly, the flat frame 10a having the bending line parts 11 formed on both sides may be supplied to the conveying roller part 110 .
이송 롤러부(110)가 절곡 리테이너(120)와 절곡 롤러부(130) 사이에 평판 프레임(10a)을 공급한다(S12). 이때, 평판 프레임(10a)에는 플랜지부(12)가 아직 형성되지 않은 상태이다.The conveying roller unit 110 supplies the flat frame 10a between the bending retainer 120 and the bending roller unit 130 (S12). At this time, the flange portion 12 is not yet formed in the flat frame 10a.
절곡 롤러부(130)가 평판 프레임(10a)을 절곡 리테이너(120) 측으로 가압함에 따라 평판 프레임(10a)의 양측에 플랜지부(12)를 형성한다(S13). 이때, 평판 프레임(10a)의 양측이 절곡 가이드부(123)의 절곡 슬릿부(124a)에 삽입된 상태에서 이동됨에 따라 플랜지부(12)를 형성한다. 즉, 평판 프레임(10a)의 양측이 절곡 슬릿부(124a)에서 삽입된 상태에서 이동되면, 평판 프레임(10a)의 양측이 절곡 슬릿부(124a)를 따라 이동되면서 수직하거나 거의 수직하게 절곡된다. 또한, 제1절곡 가이드부(124)는 유입측이 절곡 서포터부(121)와 수평하게 연장되고, 절곡 롤러부(130) 측으로 갈수록 점차적으로 세워지므로, 평판 프레임(10a)의 양측이 부드럽게 세워지면서 절곡됨에 따라 플랜지부(12)가 형성될 수 있다.As the bending roller unit 130 presses the flat frame 10a toward the bending retainer 120, flange portions 12 are formed on both sides of the flat frame 10a (S13). At this time, both sides of the flat frame 10a form the flange portion 12 as it is moved while being inserted into the bending slit portion 124a of the bending guide portion 123. That is, when both sides of the flat frame 10a are moved while being inserted in the bending slit portion 124a, both sides of the flat frame 10a are bent vertically or almost vertically while moving along the bending slit portion 124a. In addition, since the inflow side of the first bending guide part 124 extends horizontally with the bending supporter part 121 and is gradually erected toward the bending roller part 130, both sides of the flat frame 10a are gently erected. As it is bent, the flange portion 12 may be formed.
절곡 롤러부(130)가 플랜지부(12)가 형성된 평판 프레임(10a)을 벤딩 롤러부(140)에 공급한다(S14). 이때, 평판 프레임(10a)은 절곡 리테이너(120)의 상측에서 슬라이딩되면서 이동된다. 또한, 평판 프레임(10a)의 플랜지부(12)는 절곡 리테이너(120)의 절곡 가이드부(123)에 의해 지지된다.The bending roller unit 130 supplies the flat frame 10a having the flange unit 12 to the bending roller unit 140 (S14). At this time, the flat frame 10a is moved while sliding on the upper side of the bending retainer 120 . Also, the flange portion 12 of the flat frame 10a is supported by the bending guide portion 123 of the bending retainer 120 .
