Abstract

A plate member manufacturing method for a mobile terminal with inserted hides is provided to obtain high touch sense and appearance by inserting various hides. A plate member manufacturing method for a mobile terminal with inserted hides includes the steps of: coating a hardener(20) for hides at one surface of a hide(10); changing the shape of the hide by hardening the hardener with a heater(40) after pressurizing the hardener coated hide between a pair of forming molds(30) of a predetermined surface shape; trimming an unnecessary part by using a punch by fixing the hardener hardened hide on a die; forming a first resin layer by injecting high temperature resin on the hardener layer by fixing the trimmed hide on an injection mold; and completing the plate member by forming a second resin layer by injecting the high temperature resin to cover the edge of the first resin layer and the hide after fixing the hide with the first resin layer on the other injection mold.

이하에서는 본 발명인 판부재 제조방법을 도면을 참조하여 상세히 설명한다.Hereinafter, a method for manufacturing a plate member of the present invention will be described in detail with reference to the drawings.

도 1 내지 도 3은 본 발명의 일 실시예인 판 부재 제조공정을 나타낸 도면이다.1 to 3 is a view showing a plate member manufacturing process which is an embodiment of the present invention.

먼저, 도 1과 같이 피혁(10)의 일면에 피혁 경화용 경화제(20)를 도포하여 경화제(20) 층을 형성한다.First, as shown in FIG. 1, a hardening agent 20 for curing leather is applied to one surface of a leather 10 to form a hardening agent 20 layer.

피혁(10)으로는 천연 가죽이나 인조 가죽이 사용된다.As the leather 10, natural leather or artificial leather is used.

그 다음, 경화제(20)가 도포된 피혁(10)을 특정의 표면 형상을 갖는 한 벌의 포밍 금형(30) 사이에 압착시키고, 히터(40)로 가열하여 경화제(20)를 경화시킴으로써 경화제(20)의 강성으로 피혁(10)의 형상을 변형시킨다.Then, the leather 10 to which the curing agent 20 is applied is pressed between a pair of forming molds 30 having a specific surface shape, heated with a heater 40 to cure the curing agent 20, and then the curing agent ( The shape of the leather 10 is deformed by the rigidity of 20).

경화제(20)로는 고온에서는 액상이나 겔 상태였다가 저온이 되면서 경화되는 실리콘이나 에폭시 등의 경화제로서의 통상적인 재료를 사용할 수 있으며, 그 밖에 통상적인 휘발성의 재료를 사용할 수 있다.As the curing agent 20, a conventional material as a curing agent such as silicone or epoxy that is cured at a high temperature in a liquid state or a gel and then becomes a low temperature can be used. In addition, a conventional volatile material can be used.

그 다음, 경화제(20)가 경화된 피혁(10)을 다이(50)에 고정하고 펀치(60)를 사용하여 불필요한 부분을 트리밍 한다.Next, the hardened leather 10 is fixed to the die 50, and the unnecessary portion is trimmed using the punch 60.

그 다음, 트리밍 된 피혁(10)을 제 1사출 금형(70)에 고정시키고, 경화제(20) 층의 위에 고온의 수지를 사출하여 제 1수지층(80)을 성형함으로써 판부재를 완성한다.Then, the trimmed leather 10 is fixed to the first injection mold 70, and a high temperature resin is injected onto the hardener 20 layer to form the first resin layer 80 to complete the plate member.

이러한 제 1수지층(80)은 휴대 단말기용 판부재를 제조하는 재료인, PC 또는 ABS 등이 사용된다.The first resin layer 80 is a material for manufacturing a plate member for a portable terminal, such as PC or ABS is used.

그 다음, 제 1수지층(80)이 형성된 피혁(10)을 제 2사출 금형(90)에 고정시키고, 제 1수지층(80)에 고온의 수지를 사출하여 제 2수지층(100)을 성형한다. 제 2수지층(100) 또한 제 1수지층(80)과 동일한 재료나 유사한 재료를 사용한다.
이때, 상기 제 2수지층(100)은 도 3에 도시된 바와 같이, 상기 피혁(10) 및 상기 제 1수지층(80)의 가장자리를 감싸도록 고온의 수지를 사출함으로서, 상기 피혁(10)과 경화제(20)와 제 1수지층(80)의 접착면의 가장자리가 쉽게 분리되는 것을 방지하도록 한다.Next, the leather 10 having the first resin layer 80 formed thereon is fixed to the second injection mold 90, and a high temperature resin is injected into the first resin layer 80 to form the second resin layer 100. Mold. The second resin layer 100 also uses the same or similar material as the first resin layer 80.
In this case, as shown in FIG. 3, the second resin layer 100 injects a high temperature resin so as to surround edges of the leather 10 and the first resin layer 80, thereby providing the leather 10. And the edge of the adhesive surface of the curing agent 20 and the first resin layer 80 to prevent the separation.

이와 같이 하여 피혁(10)이 인서트 된 휴대 단말기용 판부재가 완성된다.In this way, the board member for portable terminals in which the leather 10 is inserted is completed.

이러한 판부재는 휴대 단말기의 외부로 드러나는 케이스나 돌출부 버튼 등에 적용할 수 있다.The plate member may be applied to a case or a protrusion button exposed to the outside of the portable terminal.

이상에서 설명한 바와 같이 본 발명은, 인체에 유익하고 촉감과 미관이 좋은 가죽 등의 피혁을 휴대 단말기용 판 부재에 인서트 함으로써, 사용자들의 기호를 충족할 수 있는 효과가 있다.As described above, the present invention has an effect of satisfying users' preferences by inserting leather, such as leather, which is beneficial to the human body and has good touch and aesthetic appearance to a plate member for a portable terminal.

이상에서는 본 발명을 특정한 실시예로써 설명하였으나, 본 발명은 상기한 실시예에 한정되지 아니하며, 특허청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형이 가능할 것이다.The present invention has been described above by way of specific embodiments, but the present invention is not limited to the above-described embodiments, and those skilled in the art without departing from the gist of the present invention claimed in the claims. Anyone can make a variety of variations.
