휴대기기 케이스 및 그 제조방법{Case for portable device and manufacturing method thereof}Case for portable device and manufacturing method

본 발명은 휴대기기 케이스에 관한 것으로, 특히 외측에 다양한 문양을 갖는 필름을 몰딩에 의한 성형시에 일체로 부착하여 미려함을 높인 휴대기기 케이스 및 그 제조방법에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile device case, and more particularly, to a mobile device case and a method of manufacturing the same, in which a film having various patterns on the outside is integrally attached during molding by molding.

최근에는 휴대기기 즉, 스마트폰, 태블릿 PC 등이 많이 보급되어 사용자가 휴대하면서 전화통화는 물론 인터넷을 통한 각종 정보 취득 및 소셜 네트워크 서비스까지 이용할 수 있게 되었다.In recent years, mobile devices, such as smart phones and tablet PCs, have been widely distributed, so that users can carry and use various kinds of information acquisition and social network services through the Internet as well as telephone calls.

그러나 이러한 휴대기기는 매우 고가로서 파손이 발생되면 많은 경제적 부담이 뒤따르며, 외관에 흠집이 발생되는 경우 미관상 보기 좋지 않기 때문에 이를 보호하기 위하여 별도로 휴대기기 케이스가 많이 사용되고 있다.However, such a mobile device is very expensive, and if a breakage occurs, a lot of economic burdens follow, and if a scratch occurs in appearance, it is not aesthetically pleasing, so a case of a mobile device is used a lot separately.

이러한 본 발명을 도면을 참조하여 상세히 설명한다.This invention will be described in detail with reference to the drawings.

도1은 본 발명에 의해 제조된 휴대기기 케이스(100)의 외관을 보인 도로서, 하나의 예로 스마트폰의 후면을 덮을 수 있는 케이스로서, 그 외측에 문양이 형성된 문양필름(110)이 사출성형시에 일체로 부착됨으로써 박리되지 않고 견고히 부착된 상태를 갖는다. 1 is a view showing the appearance of a mobile device case 100 manufactured by the present invention, as an example of a case that can cover the back of the smart phone, the pattern is formed on the outside of the pattern film 110 injection molding By being integrally attached at the time, it has a state which is firmly attached without peeling.

도2는 문양필름(110)을 휴대기기 케이스(100)의 사출성형시에 일체로 형성하는 과정을 설명하기 위한 도로서, 하부금형(200)의 바닥에 상부면이 상측을 향하도록 위치시킨 다음 상부금형(210)을 체결시킨 후 멜트형태의 합성수지재를 투입함으로써 휴대기기 케이스(100)의 외측에 문양필름(110)이 열에 의해 부착되어 일체화된다.Figure 2 is a view for explaining the process of integrally forming the pattern film 110 during the injection molding of the mobile device case 100, the upper surface is positioned on the bottom of the lower mold 200 facing upwards After fastening the upper mold 210 by inserting a synthetic resin material in the form of a melt, the pattern film 110 is attached to the outside of the mobile device case 100 by heat to be integrated.

이때, 휴대기기 케이스(100)는 TPU, 실리콘, 우레탄, 고무 등 연질의 재질로 성형되며, 문양필름(110)은 PET, PC, PVC 등의 재질로 형성된다.At this time, the mobile device case 100 is molded of a soft material such as TPU, silicon, urethane, rubber, the pattern film 110 is formed of a material such as PET, PC, PVC.

이렇게 문양필름(110)이 휴대기기 케이스(100)의 외측에 견고히 부착되도록 하기 위하여 아래와 같은 처리과정을 거친다.
The pattern film 110 is subjected to the following process in order to be firmly attached to the outside of the mobile device case 100.

이를 도3을 참조하여 설명하면, 먼저 투명의 필름(111)에 문양을 인쇄나 음양 등의 다양한 방법에 의해 형성시킨 다음 그 문양이 형성된 면의 상부에 투명 잉크를 실크 스크린에 의해 인쇄하게 되며, 이는 문양이 형성된 필름(111)의 상부면에 부착력을 강화화기 위한 작업공정으로서, 투명잉크에 경화제 8~12중량%와 희석용제 28~32중량%를 혼합한 다음 250목의 실크 스크린에 의해 5~10㎛의 두께를 갖도록 인쇄하여 1도 인쇄층(112)을 형성한다.Referring to FIG. 3, first, a pattern is formed on the transparent film 111 by various methods such as printing or yin yang, and then transparent ink is printed on the upper surface of the pattern on which the pattern is formed by a silk screen. This is a work process for strengthening the adhesive force on the upper surface of the patterned film 111, by mixing 8 to 12% by weight of the curing agent and 28 to 32% by weight of the diluent solvent in a transparent ink and then 5 by silk screen of 250 neck 1 degree printed layer 112 is formed by printing to have a thickness of ˜10 μm.

1도 인쇄층(112)의 형성후에 콘베이어 건조기를 이용하여 80~90℃(바람직하게는 85℃)의 온도에서 1차 건조를 행하고, 이후 밀페된 오븐 건조기에서 75~85℃(바람직하게는 85℃)의 온도로 30분간 추가로 2차 건조를 행한다.After formation of the first degree printing layer 112, the primary drying is carried out at a temperature of 80 to 90 ° C. (preferably 85 ° C.) using a conveyor dryer, and then 75 to 85 ° C. (preferably 85 to an airtight oven dryer). Second drying is further performed at a temperature of (° C) for 30 minutes.

다음으로 1도 인쇄층(112)의 상부면에 2도 인쇄층(113)을 형성하게 되는데, 원하는 색의 컬러잉크를 250목의 실크 스크린에 의해 5~10㎛의 두께를 갖도록 인쇄하여 2도 인쇄층(113)을 형성한다.Next, a second degree printing layer 113 is formed on the upper surface of the first degree printing layer 112. The color ink of a desired color is printed by a silk screen of 250 necks so as to have a thickness of 5 to 10 μm, and the second degree is printed. The printed layer 113 is formed.

이때, 컬러 잉크에는 경화제 8~12중량%와 희석용제 8~12중량%가 혼합되어 있으며, 이 컬러잉크의 색이 투명잉크로 인쇄된 1도 인쇄층(112)과 투명의 필름(111)을 통하여 외부로 표출되어 문양필름(100)이 색감을 가지게 되는 것이다.In this case, 8 to 12% by weight of the curing agent and 8 to 12% by weight of the diluent solvent are mixed in the color ink, and the first-degree printing layer 112 and the transparent film 111 in which the color of the color ink is printed with a transparent ink are prepared. Exposed to the outside through the pattern film 100 will have a color.

2도 인쇄층(113)의 형성후에 콘베이어 건조기를 이용하여 80~90℃(바람직하게는 85℃)의 온도에서 표면건조를 행한다.After formation of the second degree printing layer 113, surface drying is performed at a temperature of 80 to 90 ° C (preferably 85 ° C) using a conveyor dryer.

이러한 2도 인쇄층(113)은 실크 스크린에 의해 인쇄됨으로써 자세히 들여다 보면 도트 형태로 인쇄되어 빈 공간이 있으므로 인쇄품질이 조밀하지 못하며, 다양한 색감을 구성하기가 힘들다.The second degree printing layer 113 is printed by a silk screen, so if you look closely, it is printed in the form of dots, so that there is a blank space, the print quality is not dense, and it is difficult to construct various colors.

따라서 2도 인쇄층(113)의 상부면에 다시 동일 색상의 컬러잉크 또는 다른 색상의 컬러잉크에 의해 3도 인쇄층(114)을 형성하게 되는데, 이때도 마찬가지로 컬러 잉크에 경화제 8~12중량%와 희석용제 8~12중량%가 혼합한 다음 250목의 실크 스크린에 의해 5~10㎛의 두께를 갖도록 인쇄하여 3도 인쇄층(114)을 형성한다.Accordingly, the third degree printing layer 114 is formed on the upper surface of the second degree printing layer 113 by color inks of the same color or color inks of different colors. In this case, 8 to 12% by weight of a curing agent is applied to the color ink. After mixing with 8 to 12% by weight of the diluting solvent and then printed to have a thickness of 5 ~ 10㎛ by 250 neck silk screen to form a three-degree printing layer (114).

이로인해 2도 인쇄층(113)과 3도 인쇄층(114)이 동일한 색상인 경우 조밀한 인쇄가 되어 인쇄면에 빈 공간이 메꿔지게 되며, 서로 다른 색상인 경우 그 색상의 조합에 의해 조밀하면서도 다양한 색상이 표출되는 것이다.As a result, when the second degree printing layer 113 and the third degree printing layer 114 have the same color, the printing becomes dense and the empty space is filled on the printing surface. Various colors are expressed.

3도 인쇄층(114)의 형성후에 콘베이어 건조기를 이용하여 80~90℃(바람직하게는 85℃)의 온도에서 1차 건조를 행하고, 이후 밀페된 오븐 건조기에서 85~95℃(바람직하게는 90℃)의 온도로 30분간 추가로 2차 건조를 행한다.After formation of the third degree printing layer 114, primary drying is performed at a temperature of 80 to 90 ° C (preferably 85 ° C) using a conveyor dryer, and then 85 to 95 ° C (preferably 90) in a sealed oven dryer. Second drying is further performed at a temperature of (° C) for 30 minutes.

계속해서 3도 인쇄층(114)의 상부면에 4도 인쇄층(115)을 형성하게 되는데, 투명잉크에 경화제 8~12중량%와 희석용제 28~32중량%를 혼합한 다음 150목의 실크 스크린에 의해 5~10㎛의 두께를 갖도록 인쇄하여 4도 인쇄층(115)을 형성한다.Subsequently, the fourth degree printing layer 115 is formed on the upper surface of the third degree printing layer 114. The transparent ink is mixed with 8 to 12% by weight of the curing agent and 28 to 32% by weight of the diluent solvent, and then 150 necks of silk By printing to have a thickness of 5 ~ 10㎛ by a screen to form a 4 degree printed layer 115.

이는 이후의 5도 인쇄층(116)과의 부착력을 높이기 위한 작업공정이다.This is a working process for increasing the adhesion with the subsequent 5 degrees printed layer 116.

4도 인쇄층(115)의 형성후에는 콘베이어 건조기를 이용하여 80~90℃(바람직하게는 85℃)의 온도에서 1차 건조를 행하고, 이후 밀페된 오븐 건조기에서 85~95℃(바람직하게는 90℃)의 온도로 30분간 추가로 2차 건조를 행한다.After formation of the fourth degree printing layer 115, the primary drying is carried out at a temperature of 80 to 90 ° C. (preferably 85 ° C.) using a conveyor dryer, and then 85 to 95 ° C. (preferably in a sealed oven dryer). Secondary drying is further performed at a temperature of 90 ° C. for 30 minutes.

마지막으로 4도 인쇄층(115)의 상부면에 5도 인쇄층(116)을 형성하게 되는데, 접착액에 희석용제 30~40중량%를 혼합한 다음 150목의 실크 스크린에 의해 5~10㎛의 두께를 갖도록 인쇄하여 5도 인쇄층(116)을 형성한다.Finally, the 5 degree printing layer 116 is formed on the upper surface of the 4 degree printing layer 115. The diluent solvent is mixed with 30 to 40% by weight of the adhesive solution, and then 5 to 10 μm by 150 neck silk screen. The printed layer 116 is formed by printing to have a thickness of 5 degrees.

5도 인쇄층(116)은 금형내에서 휴대폰 케이스(100)의 사출성형시 연질의 휴대폰 케이스(100)의 외측면에 문양필름(110)이 견고히 부착되도록 하는 층으로서, 금형내로 멜트형태로 투입되는 합성수지재의 열에 의해 녹아 휴대폰 케이스(100)와 일체형으로 견고히 부착되는 것이다.The fifth degree printing layer 116 is a layer for firmly attaching the pattern film 110 to the outer surface of the soft mobile phone case 100 during injection molding of the mobile phone case 100 in the mold, and is introduced into the mold in a melt form.
