본 고안은 마스크와 프레임의 용접구조에 관한 것으로, 특히 크립과 홀더가 용접된 프레임에 마스크를 용접하기 위한 용접구조에 관한 것이다.The present invention relates to a welding structure of a mask and a frame, and more particularly, to a welding structure for welding a mask to a frame welded to a creep and a holder.
주지하는 바와 같이 프레임에 마스크를 고정하기 위하여 종래에는 제1도로 보인 바와 같이 마스크(101)의 스커트(1O2)와 프레임(103)이 겹치는 부위에 전기용접봉을 대고 전류를 흘려 줌으로써 용접이 이루어지도록 하였던 것이다.As is well known, in order to fix the mask to the frame, as shown in FIG. 1, the welding is performed by applying an electric welding rod to a portion where the skirt 102 and the frame 103 of the mask 101 overlap with each other. will be.
그러므로 그 두께가 매우 얇은 스커트(102)와 프레임(103)간에 점용접된 상태이어서 실제로는 제2도로 보인 바와 같이 2 개소에 용접을 실시함으로써 용접 상태의 안정을 도모하였던 것이다.Therefore, it is in the state of spot welding between the very thin skirt 102 and the frame 103, and as shown in FIG. 2, the welding is performed at two places to stabilize the welding state.
그러나 근본적으로 마스크(101)의 두께가 매우 얇으므로 진동등에 의하여 용접상태가 손상되는 경우가 있으며, 용접점이 두개소씩이므로 공수가 많게 되고 두개씩 용접함으로 인하여 변형 응력이 크게 발생되는 문제점이 있는 것이다.However, since the thickness of the mask 101 is very thin, there is a case where the welding state is damaged by vibration, etc., and there are problems in that deformation stress is largely generated by welding two by two places because of two welding points.
상술한 종래의 문제점을 감안하여 본 고안의 목적은 한점의 용접으로 마스크와 프레임을 두번 용접한 것과 대등한 효과가 발생하도록 한 마스크와 프레임의 용접구조를 제공하는 것이다.It is an object of the present invention in view of the above-mentioned conventional problems to provide a welding structure of a mask and a frame such that an effect equivalent to welding the mask and the frame twice by one point of welding occurs.
상술한 목적을 달성하기 위하여 본 고안은 마스크의 스커트가 프레임의 둘레에 끼워지도록 하고 이들의 둘레에 용접부가 형성되도록 하되, 프레임의 일측에 형성된 관통공과, 관통공에 마스크의 절곡된 스커트가 끼워지고 재차 절곡되어 "U"형 단면을 이룬 상태에서 용접이 실시되도록 하여서된 중첩용접부로 구성된 마스크와 프레임의 용접구조를 제안한다.In order to achieve the above object, the present invention allows the skirt of the mask to be fitted around the frame and the welded portion is formed around them, but the through hole formed on one side of the frame and the bent skirt of the mask are inserted into the through hole, We propose a welding structure of a mask and a frame composed of overlapping welds which are bent again to form a welding in a state of forming a “U” cross section.
상술한 구성에 의하여 본 고안은 한번의 용접으로 마스크와 프레임을 두번 용접한것과 대등한 상태가 되어 용접점이 진동등에 의하여 쉽게 손상될 우려가 없으며, 또한 용접점 수를 반으로 줄일 수 있게 되므로 공수를 크게 감소시켜 인건비 절감에 기여하고 생산성을 향상시킬 수 있게 되는 것이며, 응력을 감소시켜 마스크 변형을 최소화하여 제품의 화질 개선에도 기여할 수 있게 되는 등의 유용한 효과가 있다.According to the above-described configuration, the present invention is in a state equivalent to welding the mask and the frame twice by one welding, so that the welding point may not be easily damaged by vibration, and the number of welding points can be reduced by half. It can be greatly reduced to contribute to labor cost reduction and to improve productivity, and to reduce the stress to minimize the deformation of the mask to contribute to the improvement of product quality.
이하 첨부된 도면을 참조하여 본 고안을 더욱 구체적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
제3도에 본 고안에 의한 마스크(1)와 프레임(3)의 용접구조를 단면도로 보였다.3 shows a welded structure of the mask 1 and the frame 3 according to the present invention in cross section.
이에서 볼 수 있는 바와 같이 본 고안은 마스크(1)의 스커트(2)에 헝성된 2개의 절개부(7)와, 절개부(7) 사이를 "U"형으로 절곡하여서 된 절곡부(4)와, 절곡부(4)의 폭이상으로 형성된 관통공(6)을 구비하여서 된 프레임(3)과 관통공(6)으로 끼운 절곡부(4) 양측에서 용접작업을 실시함으로써 하나의 용접점이 형성되도록 하여서 된 것이다.As can be seen from the present invention, the present invention provides two cutouts 7 formed on the skirt 2 of the mask 1 and a bent portion 4 formed by bending the cutout portion 7 in a “U” shape. ) And a welding operation on both sides of the bent portion 4 fitted with the through hole 6 and the frame 3 having the through hole 6 formed over the width of the bent portion 4. It was made to form.
이와 같이 된 본 고안은 프레임(3)의 양측에 마스크(1)의 스커트(2)가 위치하며 일체로 용접된 중첩용접부(5)가 형성된 상태이므로 외부의 진동이 가하여 지더라도 프레임(3)을 중심으로 2지점의 스커트(2)가 용접된 상태이어서 용접상태가 손상됨을 방지할 수 있게 되는 것이며, 아울러 하나의 용접점을 형성하면 충분하므로 용접점 개소를 줄일 수 있어서 용접으로 인한 응력의 발생을 억제하여 마스크(1)의 변형을 방지할 수 있게 된다.In the present invention, the skirt 2 of the mask 1 is positioned on both sides of the frame 3, and the overlap welding portion 5 welded integrally is formed, so that the frame 3 is applied even when external vibration is applied. Since the skirt 2 of two points is welded to the center, it is possible to prevent the welding state from being damaged. In addition, since one welding point is sufficient, the welding point can be reduced, thereby generating stress due to welding. By suppressing, deformation of the mask 1 can be prevented.
