이동통신 단말기의 내장형 배터리팩용 접착테이프{ADHESIVE TAPE FOR THE INNER BATTERY PACK OF CELLULAR PHONE}Adhesive tape for built-in battery pack of mobile communication terminal {ADHESIVE TAPE FOR THE INNER BATTERY PACK OF CELLULAR PHONE}

본 발명은 이동통신 단말기의 내장형 배터리팩을 제작하기 위한 접착테이프에 관한 것이고, 더 상세하게는 작업자의 수작업시 접착면의 접착력이 약화되는 것을 방지하면서 보이드에 의한 제품의 신뢰도가 약화되는 것을 방지할 수 있는 이동통신 단말기의 내장형 배터리팩용 접착테이프에 관한 것이다.
The present invention relates to an adhesive tape for manufacturing a built-in battery pack of a mobile communication terminal, and more particularly, to prevent the reliability of a product from being weakened by voids while preventing the adhesive force of the adhesive surface from being weakened during the manual operation of an operator. It relates to an adhesive tape for a built-in battery pack of a mobile communication terminal.

종래, 휴대전화와 같은 이동통신 단말기에는 전원공급을 위한 하드형태의 배터리팩이 결합되었다. Conventionally, a hard battery pack for power supply is combined with a mobile communication terminal such as a cellular phone.

최근에는 기술이 발달함에 따라서, 이동통신 단말기의 전원공급용 배터리팩은 도 1에 도시된 바와 같이 배터리와 보호회로가 실장된 회로기판(미도시)이 외장체(10)의 수납부(14)에 수납되고, 이러한 수납부(14)를 한정하는 외장체(10)의 테두리(12)의 상부는 접착테이프(20)가 커버하고 있는 형태의 내장형 배터리팩이 사용되고 있다. 접착테이프(20)는 배터리팩의 쇼트방지를 주목적으로 하며, 외부의 충격으로부터 회로기판을 보호하는 역할을 수행한다.Recently, with the development of technology, a battery pack for power supply of a mobile communication terminal has a circuit board (not shown) mounted with a battery and a protection circuit as shown in FIG. 1. The built-in battery pack of the form in which the adhesive tape 20 covers the upper part of the edge 12 of the exterior body 10, which is accommodated in the housing unit 14, is defined. The adhesive tape 20 mainly serves to prevent short circuit of the battery pack, and serves to protect the circuit board from external shock.

통상적인 접착테이프(20)는 그의 접착면에 이형지(22)가 부착되어 있으며, 접착테이프(20)와 이형지(22)는 거의 동일한 크기로 유지되었고, 이러한 크기는 외장체(10)의 외형 크기와 거의 동일하였다. 그리고, 접착테이프(20)의 접착면은 편평한 평면상태를 유지하고 있었다.In the conventional adhesive tape 20, the release paper 22 is attached to the adhesive surface thereof, and the adhesive tape 20 and the release paper 22 are maintained at about the same size, and this size is the outer size of the exterior body 10. Was almost the same as The adhesive face of the adhesive tape 20 was kept in a flat plane state.

이러한 내장형 배터리팩을 제작하는 과정에서, 작업자(미도시)는 한 손으로 접착테이프(20)를 파지한 상태에서 다른 손으로 이형지(22)를 제거한 후 접착테이프(20)의 편평한 접착면을 외장체(10)의 테두리(12) 상부와 수납부(14)에 수납된 회로기판의 표면에 부착시켰다.In the process of manufacturing the built-in battery pack, a worker (not shown) removes the release paper 22 with the other hand while holding the adhesive tape 20 with one hand, and then covers the flat adhesive surface of the adhesive tape 20. It was attached to the upper part of the edge 12 of the sieve 10 and the surface of the circuit board accommodated in the accommodating part 14.

이때, 작업자가 수작업으로 접착테이프(20)의 양단을 파지하는 과정에서 접착면에 이물질 등이 묻어서 접착력이 약화되었고 또한 접착테이프(20)의 테두리를 외장체(10)의 테두리(12)에 일치시키기 위하여 정신을 집중하므로 작업피로도가 증가하였다. 이는 내장형 배터리팩의 제품 신뢰도를 저하시켰고 또한 작업능률을 저하시키는 요인으로 작용하였다.At this time, in the process of the worker holding both ends of the adhesive tape 20 by hand, the adhesive force is weakened by burying foreign substances on the adhesive surface, and the edge of the adhesive tape 20 coincides with the edge 12 of the exterior body 10. Work fatigue increased as the mind was concentrated to make it work. This lowered the product reliability of the built-in battery pack and also acted as a factor to reduce the work efficiency.

한편, 작업자의 수작업하에서는 접착테이프(20)의 접착면과 외장체(10)의 수납부(14)에 수납된 회로기판의 표면 사이에 보이드(void)가 생성될 수 있으며, 이는 이동통신 단말기의 사용과정에서 회로기판의 표면에서 발산하는 열에 의하여 보이드가 확대되고, 심한 경우 접착테이프(16)의 접착력을 심하게 약화시켜서 내장형 배터리팩의 수명을 단축시키는 요인으로 작용하였다.On the other hand, a void may be generated between the adhesive surface of the adhesive tape 20 and the surface of the circuit board accommodated in the accommodating portion 14 of the exterior body 10 under the manual operation of the operator. In the process of use, the voids are enlarged by the heat radiating from the surface of the circuit board, and in severe cases, the adhesive force of the adhesive tape 16 is severely weakened, thereby acting as a factor of shortening the life of the internal battery pack.

대한민국 공개특허공보 제1997-0008705호(제1특허문헌)에는 인위적인 방법에 의해 테이프를 부착시키기 때문에 생산성이 크게 떨어질 뿐만 아니라 정확하게 태핑하기가 어렵고 절연불량이 많이 발생되는 문제점을 해결하기 위한 자동태핑장치가 개시되어 있다. 상기 제1특허문헌의 기술에 따르면, 작동암과 핑거의 작동에 의해서 태핑을 실시하므로 접착면의 접착력이 약화되는 것을 방지할 수 있지만 보이드의 생성에 의한 접착테이프의 접착력이 약화되는 것을 근본적으로 방지할 수 없었고 또한 그 구조가 복잡하다는 문제점이 있었다.
Korean Patent Laid-Open Publication No. 1997-0008705 (first patent document) is an automatic tapping device to solve the problem that not only the productivity is greatly reduced, but also it is difficult to accurately tap and many insulation defects are caused by attaching the tape by an artificial method. Is disclosed. According to the technique of the first patent document, since the tapping is performed by the operation of the operating arm and the finger, it is possible to prevent the adhesive force of the adhesive surface from being weakened, but it is essentially prevented from weakening the adhesive force of the adhesive tape due to the generation of voids. There was also a problem that the structure was complicated.

이하, 첨부도면을 참조하여 본 발명에 따른 이동통신 단말기의 내장형 배터리팩용 접착테이프에 대하여 설명한다. Hereinafter, an adhesive tape for a built-in battery pack of a mobile communication terminal according to the present invention will be described with reference to the accompanying drawings.

먼저, 이동통신 단말기의 내장형 배터리팩용 접착테이프는 배터리와 보호회로가 실장된 회로기판(미도시)이 수납되는 수납부와 상기 수납부를 한정하는 테두리를 갖는 외장체의 개방상부를 덮기 위한 부재로서, 배터리팩의 쇼트방지를 주목적으로 하며, 외부의 충격으로부터 회로기판을 보호하는 역할을 수행한다.First, the adhesive tape for a built-in battery pack of a mobile communication terminal is a member for covering an open part of an outer body having an accommodating part and an edge defining the accommodating part, in which a battery board and a circuit board (not shown) on which a protection circuit is mounted are accommodated. Its main purpose is to prevent short-circuits of battery packs and protects circuit boards from external shocks.

본 발명에 따르면, 배터리팩용 접착테이프(100)는 소정 면적의 접착면을 갖는 접착시트(130)를 포함한다. 접착시트(130)는 외장체의 개방상부에 직접 접착하는 부분으로서, 테두리 상부와 상기 수납부에 수납되는 회로기판의 표면에 직접 접촉하게 된다. 상기 접착면은 접착시트(130)의 일면에 통상의 접착제를 도포함으로써 형성된다. 접착제의 종류에 대한 상세한 설명은 생략한다.According to the present invention, the adhesive tape 100 for a battery pack includes an adhesive sheet 130 having an adhesive surface of a predetermined area. The adhesive sheet 130 directly adheres to the open upper portion of the exterior body and directly contacts the upper edge of the edge and the surface of the circuit board accommodated in the housing. The adhesive surface is formed by applying a general adhesive on one surface of the adhesive sheet 130. Detailed description of the type of adhesive will be omitted.

배터리팩용 접착테이프(100)는 접착시트(130)의 접착면에 대면하는 평면을 갖고 상기 접착면의 면적보다 큰 제1면적의 제1이형지(110)와, 접착시트(130)와 제1이형지(110) 사이에 위치하고 상기 제1면적보다 작은 제2면적을 가지며 상기 접착면에 접촉하는 접촉면은 엠보싱처리되어 있는 제2이형지(120)를 더 포함한다.The adhesive tape 100 for the battery pack has a plane facing the adhesive surface of the adhesive sheet 130 and has a first release paper 110 having a first area larger than that of the adhesive surface, and the adhesive sheet 130 and the first release paper. The contact surface between the 110 and having a second area smaller than the first area and in contact with the adhesive surface further includes a second release paper 120 which is embossed.

제1이형지(110)와 제2이형지(120)는 접착시트(130)의 접착면을 보호하기 위한 부재로서, 상기 접착면을 상기 외장체의 개방상부에 접착시키기 위하여 미리 상기 접착면으로부터 분리된다. 접착시트(130)의 접착면에 직접 접촉하는 제1이형지(110)와 제2이형지(120)의 접촉면은 추후 분리작업이 용이하게 수행될 수 있도록 표면가공된다.The first release paper 110 and the second release paper 120 are members for protecting the adhesive surface of the adhesive sheet 130, and are separated from the adhesive surface in advance in order to adhere the adhesive surface to the open upper portion of the exterior body. . The contact surface of the first release paper 110 and the second release paper 120 in direct contact with the adhesive surface of the adhesive sheet 130 is surface processed to facilitate the separation operation later.

접착시트(130)의 접착면에 접촉하는 제1이형지(110)의 접촉면은 평면상태로 유지되어 있으므로, 제1이형지(110)의 접촉면과 접촉하는 접착시트(130)의 접착면의 접촉부분은 평면부를 유지한다. 한편, 제2이형지(120)의 엠보싱처리된 접촉면이 접촉하는 접착시트(130)의 접착면의 접촉부에는 엠보싱 형상이 전사되어 엠보싱부를 형성한다. 결과적으로, 제1이형지(110)와 제2이형지(120)를 분리한 상태에서 접착시트(130)의 접착면은 도 3에 표시된 바와 같이 평면부와 엠보싱부로 구분될 수 있다.Since the contact surface of the first release paper 110 in contact with the adhesive surface of the adhesive sheet 130 is maintained in a flat state, the contact portion of the adhesive surface of the adhesive sheet 130 in contact with the contact surface of the first release paper 110 is Keep the flat part. Meanwhile, an embossed shape is transferred to the contact portion of the adhesive surface of the adhesive sheet 130 to which the embossed contact surface of the second release paper 120 contacts, thereby forming an embossed portion. As a result, the adhesive surface of the adhesive sheet 130 in the state in which the first release paper 110 and the second release paper 120 are separated may be divided into a flat portion and an embossed portion, as shown in FIG. 3.

접착시트(130)의 접착면에 있어서, 평면부는 상기 외장체의 테두리에 직접 접착되어 밀착성을 향상시킨다. 엠보싱부는 상기 외장체의 수납부의 크기에 대응하는 크기를 갖는 것이 바람직하다. 이는, 상기 외장체의 수납부에 수납되는 회로기판과 상기 접착면 사이에 보이드가 형성된 상태에서 상기 회로기판으로부터 열이 발산하여도, 상기 접착면의 엠보싱부에 의해서 상기 보이드는 팽창하지 않고 소멸될 수 있기 때문이다.In the adhesive surface of the adhesive sheet 130, the flat portion is directly bonded to the edge of the exterior body to improve the adhesion. Preferably, the embossed portion has a size corresponding to the size of the housing portion of the exterior body. This means that even if heat is emitted from the circuit board in a state where voids are formed between the circuit board accommodated in the housing part of the exterior body and the adhesive surface, the voids are eliminated without expansion by the embossing portion of the adhesive surface. Because it can.

한편, 작업자가 제1이형지(110)를 파지한 상태에서 접착시트(130)의 접착면을 상기 외장체의 개방상부에 용이하게 접착시킬 수 있도록, 제1이형지(110)와 제2이형지(120)에는 적어도 2개의 절단부(C)를 형성할 수 있다. 이때, 작업자는 절단부(C)들 사이에 위치하는 절취부(R)를 제거함으로써 노출되는 접착시트(130)의 접착면을 상기 외장체의 개방상부에 먼저 접착시킨 후 제1이형지(110)와 제2이형지(120)의 나머지 부분을 제거하면서 상기 외장체의 개방상부에 접착시킨다. 이는 작업자의 손이 접착시트(130)의 접착면에 직접 접촉하는 것을 방지하므로, 상기 접착면의 접착력이 약화되는 것을 방지할 수 있다.On the other hand, the first release paper 110 and the second release paper 120 so that the worker can easily adhere the adhesive surface of the adhesive sheet 130 to the open upper portion of the exterior body in a state of holding the first release paper 110. At least two cut portions (C) can be formed. At this time, the operator first adheres the adhesive surface of the adhesive sheet 130 exposed by removing the cut portion R positioned between the cut portions C to the open upper portion of the exterior body, and then the first release paper 110 and the first release paper 110. The remaining part of the second release paper 120 is attached to the open upper portion of the exterior body. This prevents the operator's hand from directly contacting the adhesive surface of the adhesive sheet 130, and thus may prevent the adhesive force of the adhesive surface from weakening.

제1이형지(110)에는 복수개의 정렬구멍(112)이 형성되고, 이는 작업자가 상기 외장체의 개방상부에 대한 접착시트(130)의 접착면의 정렬작업을 원활하게 수행할 수 있도록 조력한다. 이때, 상기 외장체에는 제1이형지(110)의 정렬구멍(112)에 대응하는 정렬부가 제공된다. 따라서, 작업자는 상기 외장체의 정렬부에 제1이형지(110)의 정렬구멍(112)을 결합시키면 상기 외장체의 개방상부에 대한 접착시트(130)의 접착면의 정렬작업이 자동으로 수행되며, 이는 작업자의 정신적 피로를 덜어준다.A plurality of alignment holes 112 are formed in the first release paper 110, which helps the operator to smoothly align the adhesive surface of the adhesive sheet 130 to the open upper portion of the exterior body. In this case, the exterior part is provided with an alignment part corresponding to the alignment hole 112 of the first release paper 110. Therefore, when the operator couples the alignment holes 112 of the first release paper 110 to the alignment portion of the exterior body, alignment of the adhesive surface of the adhesive sheet 130 to the open upper portion of the exterior body is automatically performed. This reduces the mental fatigue of the worker.

제2이형지(120)의 제2면적은 제1이형지의 제1면적보다 작게 유지되고 또한 접착시트(130)의 접착면의 면적보다 작게 유지할 수 있다. 결과적으로, 접착시트(130)의 접착면에 있어서, 제2이형지(120)의 접촉면과 접촉함으로써 형성되는 엠보싱 형상은 제2이형지(120)의 면적과 접촉부위에 따라서 다양하게 형성될 수 있다.The second area of the second release paper 120 may be kept smaller than the first area of the first release paper and smaller than the area of the adhesive surface of the adhesive sheet 130. As a result, in the adhesive surface of the adhesive sheet 130, the embossed shape formed by contacting the contact surface of the second release paper 120 may be variously formed according to the area and the contact portion of the second release paper 120.
