도4는 키패드의 구성도4 is a block diagram of a keypad

본 발명은 휴대폰 키패드를 형성하는　키를 러버에 부착하는 작업시, 각각의 키의 접착 강도를 균일하게　 배분 가능하게　발명된 한쌍의 지그를 이용하여 난 접착제로 형성된 물체간의 접착력을 향상시키고 안정적으로 접착시킬 수 있는 휴대폰 키패드용 지그에 관한 것이다. 　The present invention improves the adhesion between the objects formed of the egg adhesive and stably bonds by using a pair of jig that has been developed so as to uniformly distribute the adhesive strength of each key in the operation of attaching the key forming the mobile phone keypad to the rubber. A jig for a mobile phone keypad that can be made.

일반적으로 휴대폰 등에는 선택된 신호를 인지하도록 PCB 기판의 접점과 대응되게 하나 이상의　키를 포함하는 키패드가 장착된다.In general, a mobile phone or the like is equipped with a keypad including one or more hot keys to correspond to the contacts of the PCB substrate to recognize the selected signal.

이와 같은 종래 기술에 의한 휴대폰용 키패드는, 먼저 금형을 통하여 각각의 키를 사출성형 후 별도의 절단장치로 절단하여 개별화시킨 다음 지그를 이용하여 실리콘 등으로 이루어진 러버에 접착 제작된다.Such a keypad for a mobile phone according to the prior art is first manufactured by injection molding each key through a mold and then cut and separated by a separate cutting device and then bonded to a rubber made of silicon using a jig.

도 2에서 도시된 바와 같이 종래 기술에 의한 휴대폰용 키패드는　사출성형된 각각의 키의 높이의 차이와 휴대폰 키패드 배열과 동일하게 제작된 키 삽입홈에 상호 대응되는　사출 성형된　각각의 키의　사이즈 차이로 인하여 하부지그에　키를　삽입후 표면에 접착제가 도포 되고　상부 지그에　러버를 고정하여 상부지그를 밀착시킬때 각각의 키에 가해지는 힘의 차이에 의해 각각의 키가　동일한 접착 강도를 가지지 못하여 불량 발생률이 증가　되며 이와 동시에 접착력이 떨어져 러버로 부터 키가 쉽게 분리되어 품질 및 신뢰성이 떨어지는 문제점을 갖는다.As shown in Fig. 2, the keypad for a mobile phone according to the related art has a difference in the height of each injection molded key and a difference in the size of each injection molded key corresponding to a key insertion groove made in the same manner as the arrangement of the mobile phone keypad. Due to this, adhesive is applied to the surface after inserting the key into the lower jig, and when the upper jig is fixed by fixing the rubber to the upper jig, each key does not have the same adhesive strength due to the difference in the force applied to each key. At the same time, there is a problem that the adhesive strength is reduced and at the same time the key is easily separated from the rubber, thereby degrading quality and reliability.

본 발명의 목적은, 휴대폰용 키패드를 형성하는　키를 러버에 부착하는 작업 시 각각의　키의 접착 강도가 균일하게　접착 가능하게　발명된 한쌍의 지그를 이용하여 난 접착제로 형성된 물체간의 접착력을 향상시키고 안정적으로 접착 시킬 수 있는 휴대폰 키패드용 지그를 제공함에 있다　It is an object of the present invention to improve the adhesion between objects formed of an egg adhesive by using a pair of jig invented so that the adhesive strength of each key is uniformly adhered when attaching the key to the phone. To provide a jig for a mobile phone keypad that can be reliably bonded

It comprises a lower jig (1) formed with a groove 15 is formed to correspond to the shape, the upper jig 10 is provided with a seating groove 14 to be able to seat the elastic material 11 and the rubber 12 Will be.

여기서, 탄성물체(11)와 러버(12)의　안착홈(14)이 요철 성형되고 상기 하부 지그(1) 상부에서 하강하는　상부지그(10)가 더 구비되며, 상기 하부 지그(1)에는　상부지그(10)의 삽입을 가이드 하기 위한 가이드 핀(17)이 복수개소 돌출 형성되고 상기　상부지그(10)는 상기 가이드핀에 대응하는 가이드홀(18)이 형성됨이 바람직하다.Here, the top seat jig 10 of the elastic body 11 and the rubber 12 of the rubber seat 12 is unevenly formed and descends from the top of the bottom jig 1, and the bottom jig 1 is further provided on the bottom jig 1. A plurality of guide pins 17 for guiding the insertion of the jig 10 are formed to protrude, and the upper jig 10 has a guide hole 18 corresponding to the guide pin.

상기 탄성물체 안착홈(14)이 요철성형된　상부지그(10)는, 러버모양으로 제작된 탄성물체(11)가 먼저 안착되고, 그 위에 러버(12)가 안착되며,　상부지그(10)에는 탄성물체(11)와 러버(12)가 정확하게 안착되도록 가이드 하기 위한 가이드 핀(13)이 복수개소 돌출 형성되어 있다.The elastic upper body jig 10 in which the elastic object seating groove 14 is unevenly formed is first mounted on the elastic body 11 made of a rubber shape, and the rubber 12 is seated thereon, and the upper upper jig 10 A plurality of guide pins 13 for guiding the elastic object 11 and the rubber 12 to be accurately seated are formed to protrude.

이때, 전술한 상부지그(10)에 밀착 고정되는 탄성물체(11)는 탄성 복원력이 뛰어난 ( 일실시예로서, 특수 스펀지, 실리콘,　고무 둥)물체로 사용함이 바람직하다At this time, the elastic object 11 that is tightly fixed to the above-described upper jig 10 is preferably used as an excellent elastic restoring force (in one embodiment, a special sponge, silicone, rubber).

또한 상기 탄성물체(11)는 러버(12)와 동일한 크기로 제작되며 쉽게 탈,부착이 가능하게 제작됨이 바람직하다.In addition, the elastic object 11 is preferably made of the same size as the rubber 12, it is preferably manufactured to be easily detachable.

이하에서, 본 발명에 따른 키패드용 지그장치(100)를 이용하는 키패드 조립과정을 살펴본다.Hereinafter, a keypad assembly process using the jig device 100 for a keypad according to the present invention will be described.

먼저 상기 하부지그(1)의 키 삽입홈(15)에 키(22)를 거꾸로 삽입 배열한 후 키의 이면에 접착제를 도포한다.First, the key 22 is inserted upside down into the key insertion groove 15 of the lower jig 1, and then an adhesive is applied to the back surface of the key.

이후, 상기 탄성물체(11)과 러버(12)의 가이드홀(16)과　상기 상부 지그(10)의 가이드 핀(13)을 이용하여 상부지그(10)의 안착홈(14)에 안정적으로 탄성물체(11)가 러버(12)가 안착 되게 된다.Subsequently, the elastic body 11 and the rubber 12 have a guide hole 16 and the guide pin 13 of the upper jig 10 is stably elastic to the seating groove 14 of the upper jig 10. The object 11 is to be seated rubber 12.

이후, 상부지그(10)로 하부지그(1)을 가압하면 상기 탄성물체(11)가 불균일하게 제작된 키(22)로 인해 발생되는 지그의 상면의 굴곡　부분은 압축되면서 각각의 키(22)에 균일하게 압력이 가해져 각각의 키들이 균일한 접착 강도를 가지도록 키의 접착이 이루어진다. (도3 참조)Subsequently, when the lower jig 1 is pressed by the upper jig 10, the bent portion of the upper surface of the jig generated by the key 22 that the elastic object 11 is unevenly manufactured is compressed and each key 22 is pressed. Pressure is applied uniformly to each key so that each key has a uniform adhesive strength. (See Fig. 3)

이후, 상기 상부지그(10)를 상승시켜 키패드(40)를 탈거시킴으로써 키의 조립이 완료된다.Then, the assembly of the key is completed by lifting the upper jig 10 to remove the keypad 40.

이와 같은 본 발명은 특히 상부지그(10)과 하부지그(1)를 가압시, 불균일하게 제작된 키(22)로 인해 발생되는 지그 상면의 굴곡을 상부지그(10)에 탄성물체(11)를 안착시킴으로써 각각의 키(22)들이 균일한 접착 강도를 가지는 키패드(40)가 제작가능하다.In the present invention as described above, when the upper jig 10 and the lower jig 1 are pressed, an elastic object 11 is applied to the upper jig 10 by bending the upper surface of the jig caused by the non-uniformly produced key 22. By seating, a keypad 40 can be manufactured in which each of the keys 22 has a uniform adhesive strength.

본 발명은 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 있어 본 발명의 기술적 사상을 벗어나지 않는 범위내에서 여러가지 치환, 변형 및 변경이 가능함으로 전술한 실시예 및 도면에 한정되는 것은 아니다.As those skilled in the art to which the present invention pertains, the present invention is not limited to the embodiments and drawings described above as various substitutions, modifications, and changes are possible without departing from the technical spirit of the present invention.

이상에서 상세히 살펴본 바와 같이, 본발명에 따른 키패드용 지그장치는, 불균일하게 제작된 키(22)로 인해 발생되는 지그 상면의 굴곡을 상부지그(10)에 탄성 물체(11)를 안착시킴으로써 각각의 키(22)들이 균일한 접착 강도를 가지는 키패드(40)가 제작 가능하게 하는 이점이 있다.As described in detail above, the keypad jig device according to the present invention, by mounting the elastic object 11 to the upper jig 10 to the bending of the upper surface of the jig generated due to the non-uniformly produced key 22, There is an advantage that the keypad 40 can be manufactured, in which the keys 22 have a uniform adhesive strength.
