본 발명은 폴더형 이동전화 단말기의 덮개부 외장 커버의 제조방법 및 그 외장 커버에 관한 것으로, 더 상세하게는 외장 커버의 구조를 알루미늄 소재의 커버부재와 알루미늄 소재의 고정부재를 용접하는 방법으로 제조하므로써 외장 커버자체의 강도를 높일 수 있도록 하고, 덮개부와 외장 커버의 조립성을 향상시키면서 그 결속력을 높일 수 있도록 하며, 외장 커버및 덮개부의 생산성을 향상시키고, 제조 원가를 낮출 수 있으며, 외관이 더욱 미려해 질 수 있도록 하는데 특징이 있는 것이다.The present invention relates to a method for manufacturing a cover part exterior cover of a clamshell mobile phone terminal and an exterior cover thereof. More particularly, the structure of the exterior cover is manufactured by welding a cover member of aluminum material and a fixing member of aluminum material. Thus, the strength of the exterior cover itself can be increased, and the binding force can be increased while improving the assembly of the cover portion and the exterior cover, the productivity of the exterior cover and the cover portion can be improved, and the manufacturing cost can be lowered. It is characteristic to make it more beautiful.

일반적으로 폴더형 이동전화 단말기는 도 1에서 보는 바와 같이 다수의 조작 버튼을 가지는 본체부(10)와, 내면(또는 외면)에 액정화면을 가지는 덮개부(20)로 이루어지며, 이들은 힌지부(30)를 통해 서로 절첩 가능하도록 결합되어 있다.In general, the foldable mobile phone terminal is composed of a main body portion 10 having a plurality of operation buttons and a cover portion 20 having an LCD screen on an inner surface (or an outer surface), as shown in FIG. 30) is coupled to each other foldable.

그리고 상기한 덮개부(20)는 액정화면을 중앙에 조립할 수 있도록 합성수지재의 몰드물로 형성하는데 이러한 몰드물은 외장을 미려하게 가공하는데 한계가 있기 때문에 대부분 그 바깥쪽 표면을 외장 커버(21)로 덧붙여 구성하고 있다.In addition, the cover part 20 is formed of a molding material of a synthetic resin material so that the LCD screen can be assembled in the center. Since the mold is limited in processing the exterior beautifully, most of its outer surface is the exterior cover 21. In addition, we configure.

이와 같이 구성된 종래의 외장 커버(21)를 도 2 및 도 3에서 볼 수 있다.The conventional exterior cover 21 configured as described above can be seen in FIGS. 2 and 3.

도 2의 경우는 금속재질의 외장 커버(21)와 별도의 몰드 커버(22)를 이중으로 준비한 후, 그 사이에 양면 접착제(23)를 개입시킨 상태에서 고열로 열처리하여 접착하는 것으로서 다음과 같은 단점이 있다.In the case of FIG. 2, the outer cover 21 and the separate mold cover 22 of metal are prepared in duplicate, and then bonded by heat treatment at high temperature in the state of intervening the double-sided adhesive 23 therebetween. There are disadvantages.

즉, 가능한 덮개부(20) 전체의 두께를 얇고 가볍게 할 목적으로 금속재질의 외장 커버(21)를 얇게 만들게 되고, 이와 같이 얇은 외장 커버(21)는 그 내측면에 체결용 나사구멍 등을 형성할 수 없어 몰드 커버(22)를 추가로 구성하게 된다.That is, in order to make the thickness of the entire cover portion 20 as thin and light as possible, the metal outer cover 21 is made thin. Thus, the thin outer cover 21 forms a screw hole for fastening on the inner side thereof. The mold cover 22 can be further comprised because it cannot.

따라서 덮개부(20) 본래의 몰드부와, 몰드 커버(22)와, 외장 커버(21)로 구성하기 때문에 부품 수는 물론, 제조 공정이 늘어나고, 원가가 높아지며, 생산성이 떨어진다.Therefore, since the cover part 20 consists of the original mold part, the mold cover 22, and the exterior cover 21, the number of parts as well as the manufacturing process are increased, the cost is high, and the productivity is low.

도 3의 경우는 외장 커버(21)를 리퀴드 메탈로 제조한 것으로서, 그 강도가 높고 표면처리를 미려하게 할 수 있는 장점이 있으나, 가격이 높고 무게가 무겁다는 단점이 있다.In the case of Figure 3, the outer cover 21 is made of a liquid metal, it has the advantage of high strength and beautiful surface treatment, but has the disadvantage of high price and heavy weight.

따라서 본 발명은 상기와 같은 종래의 문제점을 감안하여 새로운 외장 커버를 제공하고자 하는 것으로, 발명의 주된 목적은 외장 커버의 구조를 알루미늄 소재의 커버부재와 알루미늄 소재의 고정부재를 용접하는 방법으로 제조하므로써 외장 커버자체의 강도를 높일 수 있도록 하는 한편, 덮개부와 외장 커버의 조립성을 향상시키고, 그 결속력을 높일 수 있도록 하는데 있으며, 더 나가서 외장 커버및 덮개부의 생산성을 향상시키고, 제조 원가를 낮추며, 외관을 더욱 미려하게 가공할 수 있도록 하는데 목적이 있는 것이다.Therefore, the present invention is to provide a new exterior cover in view of the conventional problems as described above, the main object of the invention by manufacturing a method of welding the cover member of the aluminum material and the fixing member of the aluminum material by the structure of the exterior cover In order to increase the strength of the outer cover itself, while improving the assembling of the cover portion and the outer cover, and to increase the binding force, further go out to improve the productivity of the outer cover and cover portion, lower the manufacturing cost, The purpose is to make the appearance more beautiful.

먼저, 본 발명에 의해 생산된 외장 커버(21)는 도 4에서 보는 바와 같이 알루미늄 재질의 커버부재(21a)와, 그 내측면에 용접의 방법으로 부착한 고정부재(21b)를 포함하여 이루어지는 것이 특징이고, 이때의 상기한 고정부재(21b)는 덮개부와 조립을 할 목적으로 복수의 나사구멍(21c)들이 형성되어있는 것이다.First, the exterior cover 21 produced by the present invention comprises a cover member 21a made of aluminum and a fixing member 21b attached to the inner side by welding as shown in FIG. 4. In this case, the fixing member 21b is a plurality of screw holes 21c are formed for the purpose of assembling the cover portion.

다음은 본 발명의 제조방법을 설명한다.The following describes the manufacturing method of the present invention.

본 발명의 제조방법은 커버부재 성형과정과, 고정부재 성형과정과, 접합재 도포과정과, 고정부재 접합과정과, 브레이징 용접과정과, 표면처리과정을 차례로 거친다.In the manufacturing method of the present invention, the cover member forming process, the fixing member forming process, the bonding material applying process, the fixing member bonding process, the brazing welding process, and the surface treatment process are sequentially performed.

즉, 임의의 형상을 가진 커버부재(21a)를 제조하기 위하여 판상의 알루미늄 소재를 프레스 가공의 방법으로 성형하는 커버부재 성형과정, 그리고 상기 커버부재의 내측면에 부착하기 위한 고정부재(21b)를 제조하기 위하여 판상의 알루미늄 소재를 프레스 가공의 방법으로 성형하는 고정부재 성형과정에서 각각의 커버부재(21a)와 고정부재(21b)를 성형한다.That is, the cover member forming process of forming a plate-shaped aluminum material by the press working method to manufacture the cover member 21a having an arbitrary shape, and the fixing member 21b for attaching to the inner surface of the cover member. In order to manufacture the cover member 21a and the fixing member 21b in the process of forming a fixing member for molding a plate-shaped aluminum material by a press working method.

이어서, 상기 고정부재 성형과정에서 생산된 고정부재의 측면에 알루미늄 용접용 접합재를 도포하는 접합재(21d) 도포과정과, 상기 접합재 도포과정을 거친 고정부재를 상기 커버부재 성형과정에서 생산된 커버부재의 내측면에 부착하는 고정부재 접합과정과, 상기 고정부재 접합과정을 거친 커버부재를 브레이징로에 넣고 가열하여, 상기한 알루미늄 용접용 접합재(21d)의 융착으로 용접하는 브레이징 용접과정을 거친다.Subsequently, a process of applying the bonding material 21d for applying an aluminum welding bonding material to the side of the fixing member produced in the forming of the fixing member and the fixing member having undergone the applying of the bonding material of the cover member produced in the forming of the cover member The fixing member bonding process attached to the inner side, and the cover member subjected to the fixing member bonding process is put into a brazing furnace and heated, and undergoes a brazing welding process of welding by welding the bonding material 21d for aluminum welding.

이때, 상기한 알루미늄 용접용 접합재는 알루미늄, 아연, 실리콘 등의 합금재이며, 이는 커버부재 및 고정부재의 용융온도보다 약간 더 낮은 용융점을 가지기 때문에 브레이징 로에서 적정한 온도로 알루미늄 소재들을 가열하였을 경우, 먼저 용융되어 용접 접합재의 역할을 하는 것이다.At this time, the bonding material for welding aluminum is an alloy of aluminum, zinc, silicon, etc., which has a melting point slightly lower than the melting temperature of the cover member and the fixing member, when the aluminum material is heated to an appropriate temperature in the brazing furnace, It is melted first to serve as a weld joint.

다음으로 상기 브레이징 용접과정을 거친 커버부재의 표면을 가공하는 표면처리과정을 거치면 외장 커버의 직접적인 생산과정이 끝단다.Next, if the surface treatment process for processing the surface of the cover member subjected to the brazing welding process, the direct production process of the outer cover is finished.

참고로 이후에는 폴더형 단말기를 이루는 덮개부의 합성수지재 몰드부와 조립을 하게 되는 바, 이때는 나사를 상기한 고정부재(21b)의 나사구멍(21c)에 체결되도록 조립하는 것이다.For reference, after the assembly with the synthetic resin mold part of the cover portion constituting the foldable terminal, in this case is to assemble the screw is fastened to the screw hole (21c) of the fixing member (21b).

이상 설명한 바와 같이 본 발명의 제조방법에 의해 제조된 외장 커버는 그 구조를 알루미늄 소재의 커버부재와 알루미늄 소재의 고정부재를 용접하는 방법으로 제조하였기 때문에 알루미늄 커버부재의 외관을 더욱 미려하게 가공할 수 있는 것은 물론, 외장 커버자체의 강도가 크게 향상되는 장점이 있고, 덮개부와 외장 커버를 조립하는데 있어서, 나사구멍을 이용하여 나사조립하기 때문에 조립성이 우수할 뿐만 아니라 체결력이 양호하며, 더 나가서 외장 커버및 덮개부의 생산성을 향상시킬 수 있게 되었고, 제조 원가를 크게 낮출 수 있는 장점이 있다.As described above, since the outer cover manufactured by the manufacturing method of the present invention is manufactured by welding the cover member of the aluminum material and the fixing member of the aluminum material, the outer cover of the aluminum cover member can be more beautifully processed. Of course, the strength of the exterior cover itself is greatly improved, and in assembling the cover part and the exterior cover, the screw holes are assembled using the screw holes, thereby providing excellent assemblability and good fastening force, It is possible to improve the productivity of the outer cover and the cover portion, there is an advantage that can significantly reduce the manufacturing cost.
