Abstract

PURPOSE: A method for making a rotational supporter in an LCD(Liquid Crystal Display) monitor is provided to improve a dimensional tolerance of the rotational supporter by making the rotational supporter through a die-casting process, not a press process. CONSTITUTION: The rotational supporter(10) is made by the die-casting process using a precise mold. The precise mold makes a left and a right bent part(12) have the same height by bending both bent parts from a main body part(11) at the same angle. As the height of tilt parts(20) installed to the both bent part have the same height, the screen is not inclined, and is uniformly moved when the monitor is rotated to a front or rear direction.

Description

ＬＣＤ 모니터 내부의 회전지지체 제조방법{Method of producing a pivotable support in LCD monitor}Method of producing a rotating support inside an LCD monitor {Method of producing a pivotable support in LCD monitor}

본 발명은 LCD 모니터 내부의 회전지지체의 제조방법에 관한 것으로, 상기 회전지지체를 다이캐스팅에 의하여 한 번에 찍어내는 회전지지체의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a rotary support inside an LCD monitor, and more particularly, to a method for manufacturing a rotary support for cutting out the rotary support at a time by die casting.

최근, 일반적인 CRT 모니터에 비해 전자파 발생과 전력소모가 작은 LCD 모니터가 각광받고 있다. 특히, LCD 모니터는 부피가 작아 설치공간을 줄일 수 있다는 점에서, 점점 그 사용량이 증가하고 있다.Recently, LCD monitors, which generate less electromagnetic waves and consume less power than conventional CRT monitors, have been in the spotlight. In particular, since LCD monitors have a small volume and can reduce installation space, their usage is increasing.

이러한, LCD 모니터의 내부에는 화면부와 전면커버 및 후면커버를 지지하는 회전지지체가 설치되어 있다.The inside of the LCD monitor is provided with a rotating support for supporting the screen, the front cover and the rear cover.

도 1은 종래의 LCD 모니터 내부의 회전지지체(10)의 구조를 나타내는 개략도이다.1 is a schematic view showing the structure of a rotating support 10 inside a conventional LCD monitor.

상기 회전지지체(10) 상부 본체부(11)의 좌우측에는 절곡부(12)가 각각 형성되어 있다. 상기 절곡부(12)에는 모니터 화면의 전후방향 경사를 조절하는 틸트부(20)가 회전가능하게 장착된다.Bending parts 12 are formed at left and right sides of the upper body part 11 of the rotatable support 10, respectively. The bent part 12 is rotatably mounted with a tilt part 20 for adjusting the inclination of the monitor screen.

또한, 상기 회전지지체(10)는 받침대(30)에 회전가능하게 지지되고 있어, 지지체 자체의 좌우 회전이 가능하도록 되어 있다.In addition, the rotatable support 10 is rotatably supported by the pedestal 30 so that the support body itself can be rotated left and right.

그런데, 상기한 종래의 회전지지체(10)는 T자형의 판을 프레스로 성형함으로써, 만들어진다.By the way, the above-mentioned conventional rotary support 10 is made by shape | molding a T-shaped board by a press.

그러나, 프레스 공정으로 상기 틸트부(20)가 결합되는 절곡부(12)를 성형할 경우, 상기 절곡부(12)가 본체부(11)와 정확하게 수직이 되지 못하는 경우가 많았다.However, in the case of forming the bent part 12 to which the tilt part 20 is coupled by the pressing process, the bent part 12 is often not perpendicular to the main body part 11 in many cases.

따라서, 상기 좌우의 절곡부(12)가 평행하게 유지되지 못하고, 받침대(30)로부터의 높이(H,H')가 다르게 되므로, 상기 절곡부(12)에 장착되는 좌우의 틸트부(20)도 평행을 이루지 못하게 되어 모니터의 화면이 기울어질뿐 아니라, 틸트부(20)를 회전시켜 화면의 전후경사를 조절할 때도, 한 쪽으로 기울어지게 화면이 이동하게 되는 단점이 있었다.Therefore, since the left and right bent portions 12 are not maintained in parallel and the heights H and H 'from the pedestal 30 are different, the left and right tilt portions 20 mounted to the bent portions 12 are different. In addition, the screen of the monitor is not tilted, and the screen is moved to be tilted to one side even when the tilt portion 20 is rotated to adjust the tilt of the screen.

본 발명은 상기의 문제점을 해결하기 위하여 안출된 것으로서, 상기 회전지지체를 프레스 공정이 아닌, 다이캐스팅 공정에 의하여 제조함으로써, 회전지지체의 치수안정성을 개선한 LCD 모니터 내부의 회전지지체의 제조방법을 제공하는 것을 목적으로 한다.The present invention has been made to solve the above problems, by manufacturing the rotary support by a die casting process, not a pressing process, thereby providing a method of manufacturing a rotary support inside the LCD monitor to improve the dimensional stability of the rotary support. For the purpose of

상기의 목적을 달성하기 위하여, 본 발명의 LCD 모니터 내부의 회전지지체 제조방법은, LCD 모니터 내부의 회전지지체를 제조하는 방법에 있어서,In order to achieve the above object, the method of manufacturing a rotating support inside the LCD monitor of the present invention, in the method of manufacturing a rotating support inside the LCD monitor,

상기 회전지지체 상부의 본체부와 상기 본체부 양측으로부터 연장되는 절곡부가 수직을 이루도록 다이캐스팅 공정에 의하여 상기 회전지지체를 제조하는 것을 특징으로 한다.The rotatable support body is manufactured by a die casting process such that a main body portion of the upper portion of the rotatable support portion and a bent portion extending from both sides of the rotatable support body become vertical.

다이캐스팅이란, 정밀한 금형을 사용하여 자동 또는 수동방식으로 소정 형상의 제품을 주조하는 방식으로 정밀도가 높아서 사후적인 기계적 다듬질 등 후처리가 거의 필요하지 않는 제품생산방법을 말한다.Die-casting refers to a method of producing a product in which a precise mold is used to cast a product of a predetermined shape in an automatic or manual manner, so that the precision is high and the post-processing such as mechanical finishing is hardly required.

이하에서는, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 대해서 자세히 설명하기로 한다. 제품의 구성요소는 종래의 회전지지체와 동일하므로, 각 구성요소에 대한 부호는 동일하게 사용하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention. Since the components of the product are the same as the conventional rotary support, the symbols for each component will be used the same.

도 2는 본 발명에 따른 회전지지체의 구조를 나타내는 사시도로서, 상기 회전지지체는 다이캐스팅에 의하여 도 2와 같은 회전지지체 형태의 금형에서 찍어낸 것이다.Figure 2 is a perspective view showing the structure of the rotary support according to the present invention, the rotary support is taken out from the mold of the rotary support form as shown in Figure 2 by die casting.

본 발명에 따른 회전지지체(10)는 상기와 같이, 좌우의 절곡부(12)가 동일한 각도로 본체부(11)로부터 절곡되어 좌우 절곡부(12)의 높이가 동일하게 되는 정밀한 금형 내에서 한 번에 찍어내어 만들어지므로, 치수안정성이 종래의 회전지지체에 비하여 아주 우수하다.As described above, the rotating support 10 according to the present invention is formed in a precise mold in which the left and right bent portions 12 are bent from the main body portion 11 at the same angle so that the height of the left and right bent portions 12 is the same. Since it is made by dipping at a time, the dimensional stability is very excellent compared to the conventional rotary support.

따라서, 좌우 절곡부(12)에 설치되는 틸트부(20)의 높이도 동일하게 되어 화면이 기울지 않으며 전후방향으로 회전 시에도 화면이 균일하게 움직이게 된다.Therefore, the heights of the tilt portions 20 installed on the left and right bent portions 12 are also the same so that the screen does not tilt and the screen moves uniformly even when rotated in the front and rear directions.

이상에서 설명한 바와 같이, 본 발명의 회전지지체 제조방법에 의하면, 회전지지체의 좌우 절곡부의 높이가 동일하게 유지되는 등 치수안정성이 개선되어 화면이 균일하게 전후이동되는 효과가 있다.As described above, according to the method of manufacturing the rotary support of the present invention, the dimensional stability is improved, such as the height of the left and right bent portions of the rotary support is maintained to be the same, and the screen is uniformly moved back and forth.

또한, 회전지지체를 한 번에 찍어내어 만들 수 있어, 복잡한 프레스 성형공정에 비하여 보다 저렴하고 편리하게 정교한 형상의 회전지지체를 만들 수 있는 장점이 있다.In addition, the rotary support can be made by cutting at a time, there is an advantage that can be made inexpensive and convenient elaborate shape of the rotary support compared to the complicated press molding process.
