이와 같은 본 발명의 전자기기 금속버튼 및 그 제조방법에 대한 실시 예를 설명하면 다음과 같다.Referring to the embodiment of the electronic device metal button and the manufacturing method of the present invention as follows.

도 1및 도 2에 도시된 바와 같이, 각종 전자기기에 사용되는 금속버튼을 제조하기 위해서는 단계(S10)∼단계(S80)를 거치게 되는 바, 먼저, 단계(S10)를 통하여 Ni, Cu, Sus, Cr, Al, Zn 등의 금속으로 이루어지는 금속키캡을 제조한 후, 금속키캡의 배면 내 표면에 공기와 모래를 이용한 센딩작업을 통해 표면을 거칠게 처리하여 센딩부(3)를 성형한다.As shown in Figure 1 and 2, in order to manufacture a metal button used for various electronic devices through the step (S10) to step (S80), first, Ni, Cu, Sus through the step (S10) After manufacturing a metal keycap made of metals such as Cr, Al, Zn, and the like, the sender 3 is formed by roughly treating the surface by using sand and sanding on the inner surface of the metal keycap.

상기 키캡부에 센딩부(3)를 형성하는 방법은 에어와 모래가 혼합된 에어분사 센딩방법, 물과 모래가 혼합된 워터 센딩방법이나 또는, 샌드페이퍼 등으로 할 수 있다.The method of forming the sending unit 3 in the keycap unit may be an air spraying method of mixing air and sand, a water sending method of mixing water and sand, or sandpaper.

상기와 같이, 키캡부 저면에 센딩부를 형성한 후에는 센딩부(3)에 붓이나 스프레이 방식으로 프라이머 접착제를 도포한 후, 상기 센딩처리된 금속키캡과 대응되는 모양의 금형 틀에 안착시킨다.As described above, after the sender is formed on the bottom of the keycap part, the primer adhesive is applied to the sender part 3 using a brush or a spray method, and then placed on a mold mold having a shape corresponding to the metal keycap.

상기 프라이머 접착제는 차후 실시되는 실리콘, 고무 우레탄, 연질합성수지 중 어느 하나로 이루어진 쿠션부재(5)를 키캡 내면에 부착되도록 하고, 센딩부는 접착력을 증강시키기 위한 것이다.The primer adhesive is to be attached to the inner surface of the keycap cushion member (5) made of any one of silicone, rubber urethane, soft synthetic resin to be carried out later, the sending portion is to enhance the adhesive force.

이때, 상기 금형틀에는 금속키캡의 외표면을 보호하고 용이한 탈형을 위하여, 단계(S30)를 통해 이형제가 도포된다.At this time, the mold is applied to the mold release agent through step (S30) to protect the outer surface of the metal keycap and easy demoulding.

이와 같이, 금형틀에 금속키캡이 안착되면, 별도의 주입기를 이용하여 소정량의 쿠션부재 액을 금속키캡의 센딩처리된 면에 주입한 다음, 금형틀을 상하부 금형틀에 위치시킨 후, 프레스로 가압·성형하게 되면, 주입된 쿠션부재가 금속키캡에 틈새 없이 완전 밀착된 상태를 이루게 된다.As such, when the metal keycap is seated in the mold, a predetermined amount of cushion member liquid is injected into the metalized surface of the metal keycap by using a separate injector, and then the mold is placed on the upper and lower molds. When pressurized and molded, the injected cushioning member is brought into close contact with the metal keycap without a gap.

이때, 상기 금속키캡에 주입된 쿠션부재는 센딩처리된 면에 균일하게 분산, 압착되고, 프레스에 의해 진공상태로 가압되는 것이다.At this time, the cushion member injected into the metal keycap is uniformly distributed and pressed on the surface subjected to the sending, and is pressed in a vacuum state by a press.

이 상태에서, 상기 금속키캡을 가열 압착하여 열 경화시키게 되면, 쿠션부재가 열 경화되면서, 금속키캡에 견고하게 완전 밀착된 상태로 결합되고, 열 경화 처리된 금속키캡을 소정 시간동안 자연 냉각시킨 후, 금형틀에서 탈형시키게 되면, 금속버튼의 제조가 완료되는 것이다.In this state, when the metal keycap is thermally cured by heat pressing, the cushion member is thermally cured, and is firmly bonded to the metal keycap in a tightly adhered state, and the metal keycap is naturally cooled for a predetermined time. If the mold is demolded, the manufacture of the metal button is completed.

상기 금속키캡에 쿠션부재를 주입하는 단계(S50)와, 프레스를 이용하여 진공·가압하는 단계(S60) 및 열경화하는 단계(S70)는 한 공정에서 순차적으로 이루어 지며, 쿠션부재 재질을 이용함에 따라, 금속버튼의 기구적인 안정감과 자연스럽고 원활한 작동감을 이룰 수 있으며, 생산에 따른 작업성과 기구적 불안성을 해결할 수 있는 것이다.The step of injecting the cushion member into the metal keycap (S50), the step of vacuum-pressing using a press (S60) and the heat curing step (S70) is made in one step in order to use the cushion member material Accordingly, the mechanical stability of the metal button and a natural and smooth operation can be achieved, and workability and mechanical instability due to production can be solved.

상기와 같은 제조방법에 의해 제조된 금속버튼(1)은 도 3 내지 도 5에 도시된 바와 같이, 전주가공에 의해 Ni, Cu, Sus, Cr, Al, Zn 등의 금속소재로 이루어진 키캡 배면이 센딩 처리되어 센딩부(3)가 형성되고, 쿠션부재가 주입되어 가압·부착 및 열 경화처리 되어 쿠션부재(5)가 부착된 구조로 이루어진 것이다.As shown in FIGS. 3 to 5, the metal button 1 manufactured by the manufacturing method as described above has a keycap rear surface made of metal material such as Ni, Cu, Sus, Cr, Al, Zn, etc. by electroforming. It is made of a structure in which the cushioning member (5) is formed by being sent, the cushioning member is injected, pressurized, adhered, and heat cured to attach the cushioning member (5).

이때, 상기 키캡부(2) 배면에 형성된 센딩부(3)에는 접착제가 도포되어 접착 층(4)이 형성되고, 쿠션부재(5)가 진공·가압된 상태로 부착되어 열 경화됨에 따라, 견고하게 부착된 상태를 이루게 된다.At this time, an adhesive is applied to the sending part 3 formed on the back of the keycap part 2 to form an adhesive layer 4, and as the cushion member 5 is attached in a vacuum and pressurized state to be thermally cured, it is firm. Attached state is achieved.

그리고 상기 쿠션부재(5)에는 돌기(5')가 일체로 돌출되며, 돌기(5')에 의해 금속버튼 작동시, 전자기기에 내설된 인쇄회로기판(PCB, 도면에 도시되지 않음)의 접점을 이루게 되는 것이다.A protrusion 5 'is integrally protruded from the cushion member 5, and when the metal button is operated by the protrusion 5', a contact point of a printed circuit board (PCB, not shown in the drawing) embedded in the electronic device is provided. Will be achieved.

이상에서와 같이, 본 발명의 금속버튼은 금속소재를 사용하여 제조되므로, 사용시 내구성이 우수하고, 열, 항온, 항습 등 환경적 요소에 의한 치수 및 모양의 변형이 거의 없으며, 대량 복제 생산이 가능하므로, 정밀한 디자인과 균일한 제품의 생산이 가능한 것이다.As described above, since the metal button of the present invention is manufactured using a metal material, it has excellent durability in use, almost no deformation of dimensions and shapes due to environmental factors such as heat, constant temperature, and humidity, and mass production is possible. Therefore, it is possible to produce a precise design and a uniform product.

이와 같이, 본 발명에 따른 전자기기의 금속버튼 및 그 제조방법을 이용함에 따라, 센딩단계에 의해 센딩부가 형성되어 쿠션부재가 완전 밀착된 상태로 견고하 게 가압·부착됨으로서, 장기간 사용에 따른 쿠션부재의 이탈을 방지할 수 있고, 제품에 대한 품질과 신뢰성을 향상시킬 수 있는 효과가 있다.As described above, according to the metal button of the electronic device and the method of manufacturing the same, a sending part is formed by the sending step so that the cushioning member is firmly pressed and attached in a state where the cushioning member is completely in contact with each other. The separation of the member can be prevented, and the quality and reliability of the product can be improved.

또한, 금속키캡에 쿠션부재를 직접 부착 하므로서, 제조공정을 최소화 하여 작업성과 생산성을 향상시킬 수 있고, 소요되는 제조원가를 절감할 수 있어 경제적이며, 금속버튼의 다양화와 기구적 불안정을 해소하여 제품의 품질과 부가가치를 높일 수 있는 효과를 얻을 수 있는 것이다.In addition, by directly attaching the cushion member to the metal keycap, the manufacturing process can be minimized to improve workability and productivity, and the required manufacturing cost can be reduced, and it is economical, eliminating the diversification of metal buttons and mechanical instability. The effect can be to increase the quality and added value of.
