실리콘이 경화되면 우레탄 필름과 일체가 되는 바, 미리 아크릴등으로 사출 성형되어 있는 사출키와 이를 결합시키면서 상기한 사출키와 우레탄 필름을 본딩재로 견고하게 결합하게 된다.When the silicone is cured, the urethane film is integrated, and the injection key and the urethane film are firmly bonded to each other by bonding the injection key, which is injection-molded with acrylic or the like, with a bonding material.

그러나, 상기한 바와 같이 키패드를 제작할 때 상기한 우레탄 필름을 핫프레스로 키패드처럼 성형하여 실리콘을 충진하고, 별도로 사출 성형된 사출 키와 본딩재로 결합시키게 되면, 상기한 키패드의 제작하는 공정에서 본딩재 도포, 경화등과 같이 공정이 너무 복잡하게 되는 문제점이 있다.However, when manufacturing the keypad as described above, when the urethane film is molded in a hot press like a keypad and filled with silicon, and combined with an injection-molded injection key and a bonding material, bonding is performed in the manufacturing process of the keypad. There is a problem that the process is too complicated, such as reapplication, curing.

따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 휴대기기용 키패드의 제조 공정을 단순화하고 경비를 절감할 수 있도록 구성한 휴대기기용 키패드 및 이에 적합한 제조 방법을 제공함에 있다.Accordingly, an object of the present invention is to provide a keypad for a portable device and a method for manufacturing the same, which are configured to simplify the manufacturing process of the keypad for a portable device and to reduce the cost.

상기한 목적을 실현하기 위하여 본 발명은, 돔 스위치를 누를 수 있도록 필름에 실리콘이 충진 경화되는 키패드와, 상기한 키패드의 상면에 결합되는 사출 키패드를 포함하는 휴대기기용 키패드에 있어서, 상기한 키패드에 형성된 하나 이상의 구멍과, 상기한 구멍에 삽입된 상태에서 종단이 융착되어 키패드와 사출 키패드를 결합시키도록 사출 키패드에 형성된 결합부를 포함함을 특징으로 한다.In order to achieve the above object, the present invention, in the keypad for a mobile device comprising a keypad filled with silicone filled hardening so as to press the dome switch, and an injection keypad coupled to the upper surface of the keypad, said keypad At least one hole formed in the, characterized in that it comprises a coupling portion formed in the injection keypad so that the end is fused in the state inserted into the hole to combine the keypad and the injection keypad.

또한, 본 발명에 따른 키패드 제조 방법은 필름을 키패드 형태로 굴곡 성형한 후 필름에 실리콘을 충진시켜 경화하고, 키패드를 사출 성형하여 상기한 실리콘이 충진된 필름과 결합시키는 것을 포함하는 휴대기기용 키패드 제조 방법에 있어서,In addition, the keypad manufacturing method according to the present invention after bending the film in the form of a keypad, the silicone filled in the film is cured, and the keypad for a mobile device comprising the injection molding of the keypad and bonding to the film filled with silicon. In the manufacturing method,

상기한 필름과 실리콘이 결합된 상태에서 키패드 형태로 프레스 가공할 때 하나 이상의 구멍을 가공하는 단계와,Processing one or more holes when press working in the form of a keypad in a state in which the film and silicon are combined;

상기한 구멍에 삽입되어 일정 부분 돌출되는 결합부가 일체 형성된 사출 키패드를 상기한 키패드에 밀착시키면서 구멍에 결합부를 삽입하는 단계와,Inserting the coupling portion into the hole while closely contacting the keypad with the injection keypad formed integrally with the coupling portion inserted into the hole and protruding from the predetermined portion;

도1은 본 발명에 따른 휴대기기용 키패드 제조 방법을 도시한 공정도로서, 본 발명에 따른 휴대기기용 키패드는 아크릴등으로 소정 형상 사출 성형된 사출 키패드(1)와, 우레탄등과 같은 재질의 필름(2)을 키패드 형상으로 굴곡 형성하고 여기에 실리콘(3)을 충진시켜 구성한 키패드(4)와, 상기한 사출 키패드(1) 및 키패드(4)를 결합시키기 위하여 사출 키패드(1)에 일체로 돌출 형성된 결합부(5) 및 키패드(4)에 형성된 구멍(6)에 의해 견고하게 결합되도록 구성되어 있다.1 is a process chart showing a keypad for a portable device according to the present invention, the keypad for a portable device according to the present invention is an injection keypad (1) molded injection molded in a predetermined shape, such as acrylic, and a film of a material such as urethane The keypad 4 formed by bending (2) in the shape of a keypad and filled with silicon 3 therein, and integrally with the injection keypad 1 in order to couple the above-described injection keypad 1 and the keypad 4 to each other. It is comprised so that it may be firmly couple | bonded by the protrusion 6 and the hole 6 formed in the keypad 4 formed.

즉, 종래와 같이 사출 키패드(1)와 우레탄 필름으로 제작된 키패드(4)를 본딩재로 부착시키지 않고, 결합부(5) 및 구멍(6)의 결합에 의해 고정되도록 함으로써, 키패드의 제작 공정을 단순화시킬 수 있게 되는 것이다.That is, the keypad manufacturing process of the keypad is made by bonding the coupling part 5 and the hole 6 without attaching the injection keypad 1 and the keypad 4 made of the urethane film with a bonding material as in the prior art. It will be possible to simplify.

상기한 키패드의 조립 공정을 설명하면 사출 키패드(1)를 아크릴등으로 사출 성형할 때 사출 키패드(1)의 배면에서 비교적 작은 직경인 결합부(5)가 성형되도록 한다.Referring to the assembly process of the keypad described above, when the injection keypad 1 is injection molded with acrylic or the like, the coupling part 5 having a relatively small diameter is formed on the rear surface of the injection keypad 1.

또한, 우레탄 필름(2)을 키패드의 형상에 적합하게 핫프레스로 성형한 후, 상기한 필름(2)을 소정 금형에 투입하게 된다.Moreover, after shape | molding the urethane film 2 by hot press suitable for the shape of a keypad, the said film 2 is put into a predetermined metal mold | die.

키패드와 같은 형상으로 성형된 필름(2)을 금형에 투입한 후, 상기한 필름(2)의 굴곡부에 실리콘(3)을 충진시키면서 돔 스위치(50)를 누를 수 있도록 형성하게 된다.After the film 2 formed in the shape of a keypad is put into a mold, the dome switch 50 may be pressed while the silicon 3 is filled in the bent portion of the film 2.

실리콘(3)이 필름(2)에 충진되면서 경화되면 상기한 필름(2)과 실리콘(3)이 결합된 키패드(4)에 구멍(6)이 형성되어 있는 상태가 되는 바, 상기한 구멍(6)은 상기한 우레탄 필름의 프레스 작업 시 동시에 형성되도록 한다.When the silicon 3 is filled into the film 2 and cured, the hole 6 is formed in the keypad 4 in which the film 2 and the silicon 3 are bonded to each other. 6) is to be formed at the same time during the press operation of the urethane film.

물론, 상기한 구멍(6)을 형성하는 작업은 생산 공정에 가장 적합하게 하는 바, 별도의 천공 공정으로 이를 수행해도 된다.Of course, the operation of forming the hole 6 is most suitable for the production process, it may be carried out in a separate drilling process.

상기한 구멍(6)은 비교적 직경이 작도록 형성하게 되는 바, 키패드(4)에 형성된 구멍(6)에 상기한 사출 키패드(1)의 결합부(5)를 삽입함과 아울러 구멍(6)으로 돌출된 결합부(5)를 초음파 융착으로 고정시키게 된다.The hole 6 is formed to have a relatively small diameter. The hole 6 is inserted into the coupling part 5 of the injection keypad 1 in the hole 6 formed in the keypad 4. The engaging portion 5 protruding to be fixed by ultrasonic fusion.

즉, 상기한 사출 키패드(1)를 키패드(4)에 결합시키기 위하여 상기한 결합부(5)를 구멍(6)에 삽입하면서 결합부(5)의 종단을 초음파등으로 융착하여 융착부(7)를 형성함으로써, 구멍(6)보다 직경이 크게 형성된 융착부(7)에 의해 사출 키패드(1)와 키패드(4)가 견고하게 결합된다.That is, in order to couple the injection keypad 1 to the keypad 4, the end of the coupling portion 5 is fused by ultrasonic waves or the like while the coupling portion 5 is inserted into the hole 6 to form a fusion portion 7. ), The injection keypad 1 and the keypad 4 are firmly coupled by the fusion portion 7 having a larger diameter than the hole 6.

상기한 키패드(4)와 사출 키패드(1)를 결합할 때는 도시되지 않은 소정 형상의 지그에 키패드(4)와 사출 키패드(1)를 안착시킨 상태에서 이를 초음파 융착기로 융착시키게 되는 것이다.When the keypad 4 and the injection keypad 1 are combined, the keypad 4 and the injection keypad 1 are seated on a jig having a predetermined shape, which is not shown, to be fused with an ultrasonic welding machine.

물론, 상기한 결합부(5)의 융착을 초음파 융착기로 하지 않고 다른 융착기로 이를 융착시켜도 되는 바, 상기한 사출 키패드(1)는 통상적으로 아크릴을 많이 사용하기 때문에 비교적 쉽게 융착이 가능하게 된다.Of course, the fusion of the coupling unit 5 may be fused with another fusion machine without using an ultrasonic fusion machine. Since the injection keypad 1 typically uses a lot of acrylic, the fusion is relatively easy.

여기서, 상기한 키패드는 항상 눌리는 힘을 받고 상부로 당기는 힘을 받지는 않기 때문에, 상기한 결합부(5)의 융착부(7)에 큰힘이 필요하지 않게 됨으로써 상기한 키패드(4)와 사출 키패드(1)의 결합이 매우 견고하게 유지된다.Here, since the keypad is not always pressed and pulled upwards, the keypad 4 and the injection keypad is not required because a large force is not required at the fusion portion 7 of the coupling portion 5. The bond of (1) is kept very tight.

상기한 바와 같이 본 발명의 키패드는 필름(2)과 실리콘(3) 사출물(충진재)를 결합시키기 위하여 종래와 같이 본딩재(53)를 도포하지 않아도 되는 바, 본딩재(53) 도포에 따른 별도의 도포 장치가 필요치 않게 된다.As described above, the keypad of the present invention does not need to apply the bonding material 53 as in the related art in order to bond the film 2 and the silicone 3 injection molding material (filling material). Application device is not necessary.

이상과 같이 본 발명은 우레탄 필름에 실리콘을 사출 성형한 키패드와 아크릴등으로 사출 성형된 사출 키패드를 조립할 때, 사출 키패드에 돌출 형성된 결합부를 키패드의 구멍에 삽입/융착시켜 고정함으로써, 본딩재 사용에 따른 공정의 복잡함을 단순화시키고 이에 따른 제조 경비를 절감할 수 있는 잇점이 있는 것이다.As described above, the present invention, when assembling the injection-molded keypad and the injection-molded injection keypad made of acrylic and the like in the urethane film, by inserting / fusion fixing the joint formed in the injection keypad in the hole of the keypad, There is an advantage that can simplify the complexity of the process and thereby reduce the manufacturing cost.
