Abstract

일체형으로 사출성형된 키를 라바와 조립한 후 리브를 제거하기 때문에 조립전 제거하는 것에 비하여 모체가 파괴되는 것을 방지하고, 조립하는 시간을 절약할 수 있어 제작비용을 절감할 수 있는 전화기용 키패드 제조방법을 제공하는데 있다. 이러한 키패드를 제조하기 위하여 복수 개로 형성되고 플랜지를 갖고 리브를 포함하는 키를 사출하는 공정과, 사출된 키의 바닥 면에 숫자 또는 문자를 인쇄하는 공정과, 인쇄면을 갖는 키를 라바와 조립하는 공정과, 조립된 키패드에 형성된 리브를 제거하는 공정을 포함한다. 상기한 리브는 키와 라바를 조립한 후, 레이저 빔으로 제거하는 것을 특징으로 한다.Since the ribs are removed after assembling the one-piece injection molded key with the lava, it prevents the mother from being destroyed and saves the time to assemble, compared to the removal before assembly. To provide a method. In order to manufacture such a keypad, a process of injecting a key having a plurality of flanges and having ribs, printing a number or letter on the bottom surface of the ejected key, and assembling a key having a printing surface with a lava And removing the ribs formed on the assembled keypad. The rib is characterized by removing the laser beam after assembling the key and the lava.
