Description

알루미늄 합금 압출재를 이용한 디스플레이 패널용 보강 프레임Reinforcement frame for display panel using aluminum alloy extrusion
본발명은, "ㄱ"자, "ㄷ"자, "1"자 또는 "ㅁ"자형 단면 형상을 가진 알루미늄 합금 압출재 4본을 동일 평면 상에서 사각틀 형상으로 밀착시킨 상태에서, 프레임부재와 디스플레이 패널 본체와 맞닿는 부분이 맞닿지 않는 부분보다 높게 단차가 형성된 알루미늄 합금 압출재를 이용한 디스플레이 패널용 보강 프레임에 관한 것이다.The present invention is a frame member and a display panel main body in a state in which four aluminum alloy extruded materials having a cross-sectional shape of "a", "c", "1", or "ㅁ" are in close contact with each other in a rectangular frame shape on the same plane. It relates to a reinforcing frame for a display panel using an aluminum alloy extruded material having a step higher than a portion in contact with the non-contact portion.
생활 수준의 향상과 전자 기술의 괄목할 만한 발전으로 고화질의 대형 표시 장치가 개발되었고, 지속적인 대형화가 이루어지고 있는 바, 브라운관으로도 불리우는 씨알티(CRT, cathod ray tube) 장치는, 각종 정보의 최종 전달 매체인 대표적인 디스플레이(display) 장치로서 텔레비젼, 컴퓨터 등에 널리 사용되어 왔으나, 여러가지 측면 특히, 40인치 이상의 대형화에서 기술적 한계를 드러내고 있다. 즉, 40인치 이상의 브라운관은 제조하기도 어려울 뿐 아니라, 대형화 시 그 두께가 과다하게 두꺼워지고 전체적인 체적이 지나치게 커짐으로써 설치 장소에 제한을 받게 됨은 물론, 과다한 크기와 중량에 의해 운반이나 핸들링에도 무리가 따르게 된다.With the improvement of living standards and the remarkable development of electronic technology, large display devices of high quality have been developed, and the continuous enlargement has been made, and the CRT (cathod ray tube) device, also called CRT, is the final information of various information. As a representative display device that is a transmission medium, it has been widely used in televisions, computers, and the like, but it exhibits technical limitations in various aspects, particularly in the enlargement of 40 inches or more. In other words, 40-inch or larger CRTs are not only difficult to manufacture, but also become too thick when they are enlarged, and their overall volume becomes too large, limiting the installation site, and causing excessive load and handling due to excessive size and weight. do.
따라서, 두께가 얇아 벽걸이형으로 설치가 가능하기 때문에 설치 장소에 거의 제한을 받지 않으며, 40인치 이상의 대화면 구현이 가능한 평판형 디스플레이 패널이 다양하게 개발되고 있는바, 평판형 디스플레이 패널은, 크게, 에프이디(FED, field emission display) 패널, 이엘(EL, electro-luminescence) 패널, 피디피(PDP, plasma display panel) 패널 등과 같이 스스로 발광하는 디스플레이 패널 장치와, 엘씨디(LCD, liquid crystal display) 패널, 이씨디(ECD, electro-chromic display) 패널 등과 같이 스스로 발광하지 못하는 디스플레이 패널 장치의 두 가지로 분류될 수 있다.Therefore, since the thickness is thin and can be mounted on a wall, the installation location is hardly limited. Various flat panel display panels capable of realizing a large screen of 40 inches or more have been developed. Display panel devices that emit light by themselves such as FED (field emission display) panels, EL (electro-luminescence) panels, plasma display panels (PDPs), liquid crystal display (LCD) panels, LCD It may be classified into two types of display panel devices which do not emit light by themselves, such as electro-chromic display (ECD) panels.
상기와 같은 여러 종류의 평판형 디스플레이 패널들 중 최근에 가장 각광을 받고 있는 것은 피디피와 엘씨디 패널로서, 두 장치는 다른 장치들에 비하여 기술 개발 속도가 빨라 이미 50인치 이상의 크기로 대형화가 이루어져 텔레비젼에 적용되고 있다. 엘씨디 패널이 보편화되면서 제조 업체간 경쟁이 과열됨에 따라 제조 원가 절감 및 벽걸이용으로 더욱 적합하도록 경량화가 더욱 절실이 요구되고 있는 바, 종래의 엘씨디 패널이나 피디피 등의 디스플레이 패널의 보강에 사용되고 있는 금속 보강 프레임은 다음과 같은 문제점이 있다.Among the various types of flat panel display panels, such as PDP and LCD panels are the most popular in recent years, the technology of the two devices is faster than other devices, and the size has been enlarged to 50 inches or more. Is being applied. As LCD panels are becoming more common, competition among manufacturers is overheating, which requires more weight savings to reduce manufacturing costs and make them more suitable for wall-mounting. Therefore, metal reinforcement is used to reinforce display panels such as conventional LCD panels and CDs. Frames have the following problems:
엘씨디 패널이나 피디피 등의 디스플레이 패널은, 도 1에 도시된 바와 같이, 디스플레이 패널 본체(11)와; 디스플레이 패널 본체(11)의 전체 측면에 걸쳐 결합되며, 합성수지 재질로 이루어진 사각틀 형상의 내측 프레임(12)과; 내측 프레임(12)의 전면(SF)과 측면(SS)에 밀착되도록 "ㄱ"자의 단면 형상을 갖는 사각틀 형상의 보강 프레임(13) 등으로 구성된다.As shown in FIG. 1, a display panel such as an LCD panel, a PD, etc., includes a display panel body 11; An inner frame 12 coupled to the entire side of the display panel body 11 and formed of a synthetic resin material; It consists of a square frame-shaped reinforcement frame 13 and the like having a cross-sectional shape of the letter "a" so as to be in close contact with the front face (S F ) and the side (S S ) of the inner frame (12).
미설명 부호 "H"는 보강 프레임(13)을 내측 프레임(12)에 결합시키기 위한 "볼트공"이다.Reference numeral "H" is a "bolt ball" for coupling the reinforcing frame 13 to the inner frame 12.
종래의 디스플레이 패널에 사용된 보강 프레임(13)은, 전기 아연도금 강판 또는 아연-알루미늄도금 강판인 갈바륨 강판 등을 프레스 가공하여 제조하는바, 도금 강판을 사각틀의 형상으로 가공하기 위하여 테두리부를 제외한 도금 강판 대부분의 면적을 차지하는 중앙부가 버려짐으로써 제조 비용을 상승시키게 된다. 또한, 도금 강판을 사용함으로써 디스플레이 패널의 경량화에 도움이 되지 못할 뿐 아니라, 운송이나 적재 보관 중 표면 도금층이 박리되는 경우 외부로 노출되는 강판 표면에 녹이 발생할 수도 있는 등의 문제가 있다.The reinforcing frame 13 used in the conventional display panel is manufactured by pressing a galvanium steel sheet, which is an electro galvanized steel sheet or a zinc-aluminum coated steel sheet, and the like. The central part, which occupies most of the area of the steel sheet, is discarded, thereby increasing the manufacturing cost. In addition, the use of the plated steel sheet may not only help to reduce the weight of the display panel, but also may cause rust on the surface of the steel sheet exposed to the outside when the surface plating layer is peeled off during transportation or loading and storage.
이러한 문제로 인하여 디스플레이 패널용 보강 프레임을 도금 강판과 같은 판재가 아닌, 압출재를 이용함으로써 보강 프레임 제조 공정 중 프레스 가공 시 버려지는 원자재 즉 판재의 손실을 최소화하여 원가 절감을 할 수 있도록 하는 동시에, 디스플레이 패널의 경량화에 도움이 되는 디스플레이 패널용 보강 프레임을 제작하였다.Due to this problem, the display panel reinforcement frame is made of extruded material, not plated steel plate, such as plated steel sheet, thereby minimizing the loss of raw materials, namely, plate materials, which are discarded during press processing during the reinforcement frame manufacturing process, and at the same time reducing display costs. A reinforcing frame for a display panel was produced to help reduce the weight of the panel.
한편, 상기와 같이 제작된 디스플레이 패널용 보강 프레임은 본체와 결합할 경우 프레임 내부와 디스플레이 패널 본체가 결합되는 프레임 내측에 테이프(14)를 부착하게 된다. 상기 테이프는 도전성을 갖는 테이프로써, EMI 차폐 및 본체에서 발생한 열을 프레임으로 방출시키는 역할 및 본체와 프레임 간의 충격 완화를 위한 목적으로 부착하는 것이다. 하지만, 이와 같이 테이프를 부착하는 공정은 공수가 많이 들고, 공정의 자동화에 역행한다는 문제점이 있었다.On the other hand, when the reinforcing frame for the display panel manufactured as described above is combined with the main body is attached to the tape 14 to the inside of the frame is coupled to the inside of the frame and the display panel body. The tape is a conductive tape and is attached for the purpose of EMI shielding and dissipating heat generated from the main body to the frame and for mitigating impact between the main body and the frame. However, the process of attaching the tape in this way takes a lot of labor, and there is a problem that the process is automated.

도 2에 도시된 바와 같이, 본 발명의 알루미늄 합금 압출재를 이용한 디스플레이 패널용 보강 프레임(2)은,As shown in Figure 2, the reinforcement frame 2 for a display panel using the aluminum alloy extruded material of the present invention,
"ㄱ"자형 단면을 가진 알루미늄 합금 압출재이며, 서로 평행하게 배열된 한 쌍의 바형 장척프레임부재(21)와; An aluminum alloy extruded material having an "a" shaped cross section and having a pair of bar elongated frame members 21 arranged in parallel with each other;
ㄱ"자형 단면을 가진 알루미늄 합금 압출재이며, 양 단부가 동일 평면 상에서 상기 두 장척프레임부재(21)의 양 동일측 단부 각각에 밀착된 상태로 회전마찰 용접에 결합되어 서로 평행하게 되는 한 쌍의 바형 단척프레임부재(22)와 상기 장·단척프레임부재(21)(22)와 디스플레이 패널 본체와 맞닿는 부분이 맞닿지 않는 부분보다 높게 단차(23)가 형성된 것을 포함하여 구성된 것을 특징으로 한다.A pair of bar-shaped aluminum alloy extruded materials having a cross-section, coupled to rotational friction welding and parallel to each other, with both ends being in close contact with each of the two same side ends of the two long frame members 21 on the same plane; The stepped frame member 22 and the long and short frame member 21, 22 and the display panel main body is characterized in that it comprises a step 23 is formed higher than the non-contacting portion.
그 외에, 본 발명의 보강 프레임은, 필요에 따라, 내측 프레임의 전면과 측면 및 배면을 보강할 수도 있는바, 이 경우, 상기 장·단척프레임부재는 "ㄱ"자형 단면이 아닌 "ㄷ"자형 단면 형상을 갖게 되며, 측면만을 보강하고자 하는 경우에는 "1"자 또는 "ㅁ"자 형상의 단면을 가질 수도 있다. 즉, 본원발명의 보강 프레임은, 알루미늄 바형 합금 압출재를 회전 마찰 용접으로 결합시킨 구조를 가짐에 특징이 있으며, 장·단척프레임부재의 단면 형상은 그 형상이 반드시 고정된 형태가 아닌, 필요에 따라 자유롭게 변화될 수 있다.In addition, the reinforcement frame of the present invention, if necessary, may reinforce the front, side and back of the inner frame, in this case, the long and short frame member is not a "b" shaped cross-section "c" shaped, It will have a cross-sectional shape, and in the case of reinforcing only the side surface, it may have a cross section of "1" or "ㅁ" shape. That is, the reinforcing frame of the present invention is characterized in that it has a structure in which an aluminum bar alloy extruded material is joined by rotational friction welding, and the cross-sectional shape of the long and short frame members is not necessarily fixed. Can be changed freely.
또한, 본 발명은 장·단척프레임부재(21)(22)와 디스플레이 패널 본체와 맞닿는 부분이 맞닿지 않는 부분보다 높게 단차(23)를 형성시킴으로써, 종전의 테이프 부착 공정을 생략하더라도 상기 테이프 부착의 효과를 대체할 수 있다. 단차의 높이는 0.4~0.6 mm 높게 형성시키는 것이 바람직하다. 알루미늄 합금 압출재를 이용하여 단차를 형성시킴으로써, 종전의 테이프 소재에 비하여 열전도도가 좋아져서열 방출 효과가 더욱 향상되고, 전자파 차폐 특성을 향상시켜줄 뿐만 아니라, 디스플레이 패널 본체와 보강 프레임 간의 충격완화의 기능을 한다. In addition, the present invention forms the step 23 higher than the portion where the long / short frame members 21 and 22 and the part in contact with the display panel body are not in contact with each other. It can replace the effect. It is preferable to form the height of a step 0.4-0.0.6 mm high.

즉, 상기와 같이 장·단척프레임부재(21)(22)와 디스플레이 패널 본체와 맞닿는 부분이 맞닿지 않는 부분보다 높게 단차를 형성시킴으로 인하여 기존의 테이프 부착 공정을 생략함으로써, 공정을 단순하게 하여 원가절감에 큰 효과가 있고, 전자파 차폐 효과를 얻을 수 있을 뿐만 아니라, 열 방출이 용이해져서 품질 향상에도 기여할 수 있는 것이다.That is, since the step is formed higher than the portion where the long / short frame members 21 and 22 and the display panel main body come into contact with each other as described above, the existing tape attaching process is omitted, thereby simplifying the process. It has a great effect on savings, not only to obtain the electromagnetic shielding effect, but also to facilitate heat dissipation, thereby contributing to quality improvement.
이상에서 살펴본 바와 같이, 본 발명의 알루미늄 합금 압출재를 이용한 디스플레이 패널용 보강 프레임은, 도금 강판을 프레스 가공하여 제조함으로써 원자재인 도금 강판의 60% 이상이 버려지는 종래의 보강 프레임에 비하여 원자재 손실이 거의 없으며, 보강 프레임의 경량화가 가능한 장점이 있으며, 표면 스크레치 등에 의해서도 녹 발생 등이 없는 장점이 있다.As described above, the display panel reinforcement frame using the aluminum alloy extruded material of the present invention has almost no raw material loss compared to the conventional reinforcement frame in which 60% or more of the plated steel sheet, which is a raw material, is discarded by pressing a plated steel sheet.

상기와 같이 바형 알루미늄 합금 압출재를 절단하여 얻어진 프레임부재 4본을 용접 결합시킨 본 발명의 보강 프레임은,As described above, the reinforcing frame of the present invention in which four frame members obtained by cutting a bar-shaped aluminum alloy extruded material are welded to each other,
압출하는 단계와; 열처리 하는 단계와; 압출재를 절단하여 프레임부재를 얻는 단계와; 프레임부재를 프레스 가공하는 단계와; 두 쌍의 바형 프레임부재를 사각틀 형상으로 지그(jig)에 고정시키는 단계와; 사각틀의 네 모서리부를 용접하는 단계와; 네 모서리부의 용접 버(burr)를 제거하는 단계 등의 순차적인 과정을 통하여 제작되는바, 여러 공정 중 가장 중요한 열처리 단계와 용접 단계를 살펴보면 다음과 같다.Extruding; Heat-treating; Cutting the extruded material to obtain a frame member; Pressing the frame member; Fixing two pairs of bar-shaped frame members to jigs in a rectangular frame shape; Welding four corners of the square frame; Produced through the sequential process, such as the step of removing the welding burr of the four corners, the most important heat treatment step and welding step of the various processes are as follows.
열처리 단계는, 알루미늄 합금 빌렛을 가열 압출한 압출재의 재질을 균질화하는 동시에 적절한 기계적 성질을 부여하기 위한 공정으로서, 두께에 따라 150∼210℃에서 1∼20시간 동안 가열하게 되는데, 온도나 사간이 하한값에 미치지 못하면 압출재의 균질성이 떨어져 내구성이 저하되며, 상한값을 초과하게 되면 강도가 부족하게 된다. 이때, 압출재의 두께는 0.8∼3.0mm 범위이다.The heat treatment step is a process for homogenizing the material of the extruded material extruded by heating the aluminum alloy billet and imparting appropriate mechanical properties. The heat treatment is performed at 150 to 210 ° C. for 1 to 20 hours depending on the thickness. If it is less than this, the homogeneity of the extruded material is lowered, the durability is lowered, and if the upper limit is exceeded, the strength is insufficient. At this time, the thickness of the extruded material is in the range of 0.8 to 3.0 mm.
용접 단계는, 동일 평면 상에서 서로 직각을 이루도록 밀착된 두 프레임부재의 밀착 경계부 즉, 사각틀의 모서리부를 용접하는 과정으로서, 알루미늄 합금의 용접에는, 레이저 용접, 미그 용접 등이 사용될 수도 있으나, 레이저 용접은, 용접 장치가 고가인 단점이 있으며, 미그 용접의 경우에는, 쉴드 가스를 공급해야 하는 등 장치가 복잡해지는 등의 단점이 있는바, 본 발명에서는 회전마찰 용접 방법이 적용된다.The welding step is a process of welding the close boundaries of the two frame members closely contacted with each other on the same plane, that is, the corners of the square frame. Laser welding, MIG welding, or the like may be used for welding the aluminum alloy. There is a disadvantage in that the welding apparatus is expensive, and in the case of mig welding, there is a disadvantage in that the apparatus is complicated, such as supplying a shield gas, and the rotation friction welding method is applied in the present invention.
상기 회전마찰 용접이란, 평탄한 원형 저면의 중심부에 돌기가 하향 돌출되어 있고, 고속으로 회전하는 용접 헤드를 이용하는 용접 방법으로써, 사각틀의 형상을 이루도록 각 모서리부에서 밀착된 두 프레임부재의 밀착 경계부 표면에, 용접 헤드를 압착시켜 용접 헤드 저면의 돌기가 프레임부재의 내부로 삽입되면서 용접 헤드 저면이 프레임부재의 표면에 밀착되도록 하는 단계와; 용접 헤드를 고속으로 회전시키는 동시에 밀착 경계부를 따라 용접 헤드를 이동시키는 단계 등을 통하여 용접이 이루어진다. 즉, 밀착된 두 프레임부재의 각 표면에 저면이 동시에 밀착된 용접 헤드가 고속으로 회전함에 따라 두 프레임부재의 표면과 용접 헤드 저면 사이에 마찰열이 발생하게 되고, 이 마찰열에 의해 두 프레임부재가 함께 용해되면서 서로 혼합 및 냉각됨으로써 두 프레임부재의 밀착 경계부가 용접된다. 이때, 용접 헤드 저면 중앙부의 돌기에 의해 두 프레임부재의 밀착 경계부 표면은 물론, 그 내부까지도 용접이 이루어지게 되며, 사각틀의 네 모서리부는 순차적으로 용접될 수도 있으나, 생산성 향상을 위하여 4개의 용접 헤드를 사용하여 네 모서리부를 동시에 용접할 수도 있다.The rotation friction welding is a welding method using a welding head which protrudes downward in the center of a flat circular bottom surface and rotates at a high speed. The friction welding of the two frame members closely contacted at each corner portion to form a rectangular frame is performed. Compressing the welding head so that the projection of the bottom of the welding head is inserted into the frame member so that the bottom of the welding head is brought into close contact with the surface of the frame member; Welding is performed by rotating the welding head at high speed and moving the welding head along the tight boundary. That is, the frictional heat is generated between the surface of the two frame members and the bottom of the welding head as the welding head rotates at a high speed at the same time the bottom surface is in close contact with each surface of the two frame members in close contact with each other, the two frame members together by the friction heat By melting and mixing with each other and cooling, the close contact between the two frame members is welded. At this time, the welding is performed not only on the surface of the close contact boundary of the two frame members, but also inside thereof by the projection of the bottom of the welding head, and the four corners of the square frame may be welded sequentially, but four welding heads may be used to improve productivity. You can also weld four corners at the same time.
한편, 상기의 프레스 가공 단계와 지그 고정 단계 및 용접 버 제거 단계를 간략하게 설명한다. 프레스 가공은 디스플레이 패널의 내측 프레임(도 1의 11) 전면과 측면에 밀착되는 상태로 최종 제작된 보강 프레임이 결합될 수 있도록, 볼트공 등이 포함된 다수의 각종 통공(H)을 형성시키기 위하여 장·단척프레임부재(21)(22)를 프레스 가공하는 단계이다. 지그 고정 단계는 회전 마찰 용접을 하기 위하여 각각 한 쌍씩의 장·단척프레임부재(21)(22)를 사각틀의 형상으로 고정하는 단계이다. 이렇게 각각 한 쌍씩의 장·단척프레임부재(21)(22)를 사각틀의 형상으로 고정시킨 후, 고정된 사각틀의 네 모서리부 각각에서 서로 밀착된 두 장·단척프레임부재(21)(22)의 밀착 결합부 4곳을 회전마찰 용접법으로 용접 결합시키고, 사각틀의 네 모서리부에 발생된 용접 버를 앤드밀로서 제거하는 단계를 통하여 제조된다.On the other hand, the press working step, the jig fixing step and the welding burr removing step will be briefly described. Press processing is to form a plurality of various holes (H) including a bolt hole, so that the final produced reinforcement frame can be coupled in close contact with the front and side of the inner frame (11 in Figure 1) of the display panel The long and short frame members 21 and 22 are press-processed. The jig fixing step is a step of fixing the pair of long and short frame members 21 and 22 in the shape of a square frame in order to perform rotational friction welding. After fixing the pair of long and short frame members 21 and 22 in the shape of a square frame, the two long and short frame members 21 and 22 are in close contact with each other at the four corners of the fixed square frame. Four closely coupled portions are weld-bonded by a rotational friction welding method, and are manufactured by removing the welding burrs generated at the four corners of the square frame as an end mill.
상기와 같이 한 쌍씩의 장·단척프레임부재(21)(22)를 사각형상으로 밀착시킨 사각틀(2)의 네모서리부를 용접하게 되면, 각 모서리부 표면에는 다양한 형태의 요철 즉, 용접 버가 돌출 형성되며, 각 모서리부의 용접 버는 앤드 밀로 제거할 수 있는 바, 상기 용접과 같이, 하나의 앤드밀로서 각 모서리의 용접 버를 순차적으로 제거할 수도 있으며, 각 모서리부에 하나의 앤드밀 즉, 두 쌍의 앤드밀을 구비하여 네 모서리부의 용접 버를 동시에 제거할 수도 있다.As described above, when the four corner portions of the rectangular frame 2 in which the pair of long and short frame members 21 and 22 are closely adhered in a rectangular shape are welded, various shapes of irregularities, that is, welding burrs protrude from the surface of each corner portion. The welding burr of each corner portion may be removed by an end mill. As in the above welding, the welding burr of each corner may be sequentially removed as an end mill, and one end mill, that is, two pairs of each end portion, may be removed. An end mill may be provided to simultaneously remove the welding burrs at the four corners.
즉, 한 쌍씩의 장·단척프레임부재(21)(22)를 지그에 사각틀(2)로 고정한 상태에서 네 모서리부를 동시에 용접한 후, 용접된 사각틀(2)을 지그와 함께 이동시킨 다음 앤드밀로서 네 모서리부의 용접 버를 동시에 제거하는 것이 생산성 측면에서 바람직하며, 용접 버 제거 과정 후 탄화수소계 세척제를 이용한 세척 및 건조를 거쳐 본 발명의 보강 프레임(2) 제품이 얻어진다.That is, the four corner portions are welded at the same time while the pair of long and short frame members 21 and 22 are fixed to the jig by the square frame 2, and then the welded square frame 2 is moved together with the jig and then as end mill. It is preferable from the viewpoint of productivity to remove the welding burr at the four corners at the same time, and after the welding burr removing process, the product of the reinforcing frame 2 of the present invention is obtained by washing and drying with a hydrocarbon-based cleaner.
