이하에서는 이러한 버스 바 제조장치의 제조과정에 대해서 설명하기로 한다.Hereinafter, a manufacturing process of such a bus bar manufacturing apparatus will be described.
도 5에는 본 발명의 일실시예에 따른 버스 바 제조과정을 나타내는 흐름도가 모식적으로 도시되어 있다.5 is a flowchart schematically illustrating a bus bar manufacturing process according to an embodiment of the present invention.
도 5를 도 1 내지 도 4와 함께 참조하여 설명하면, 먼저, 전도성 재료가 코팅된 금속재의 제1 전도성 재료(S)가 준비된다. 제1 전도성 재료(S)는 제1 릴(110) 상에서 일측으로부터 일방향으로 연속적으로 공급될 수 있다(S100). 이 때, 제1 전도성 재료(S)는 폭 방향으로 동일한 두께를 갖도록 가공될 수 있다.Referring to FIG. 5 with reference to FIGS. 1 to 4 , first, a first conductive material S of a metallic material coated with a conductive material is prepared. The first conductive material (S) may be continuously supplied in one direction from one side on the first reel (110) (S100). At this time, the first conductive material (S) may be processed to have the same thickness in the width direction.
이어서, 평면상에서 공급되는 제1 전도성 재료(S)는 적어도 하나 이상의 절삭부(120) 및 연삭부(130)를 통과하면서 평면가공이 수행될 수 있다. 이 때, 제1 전도성 재료(S)는 기설정된 조건에 따라서 적어도 하나 이상의 절삭부(120) 및 연삭부(130)를 통하여 동시 또는 선택적으로 적어도 1회 이상의 절삭 및 연삭 가공이 수행될 수 있다(S200). 여기서, 본 발명에 따르면, 이러한 절삭 및 연삭 공정이 수행되는 경우, 제1 전도성 재료(S)는 폭 방향으로 불규칙적이고 비균일한 두께(t)를 갖도록 가공됨으로써, 제2 전도성 재료(S2)로 가공될 수 있다(S300).Subsequently, the first conductive material (S) supplied on the plane may be subjected to plane processing while passing through at least one cutting part 120 and the grinding part 130 . At this time, the first conductive material S may be simultaneously or selectively subjected to at least one cutting and grinding process through at least one cutting unit 120 and grinding unit 130 according to a preset condition ( S200). Here, according to the present invention, when such a cutting and grinding process is performed, the first conductive material (S) is processed to have an irregular and non-uniform thickness (t) in the width direction, thereby forming the second conductive material (S2). It can be processed (S300).
본 발명이 도시하는 도면에는 제1 전도성 재료(S)가 절삭 및 연삭될 수 있는 예시를 나타내고 있으나 전도성 재료로써, 예를 들어 금속판재의 물성을 변화시키지 않는 범위에서 폭 방향으로 상이한 두께를 갖는 형상을 달성할 수 있는 가공 방식이면 특별히 한정되지 않는다.Although the drawings shown by the present invention show examples in which the first conductive material (S) can be cut and ground, as a conductive material, for example, a shape having a different thickness in the width direction within a range that does not change the physical properties of the metal plate material It is not particularly limited as long as it is a processing method that can achieve
이 후, 제2 전도성 재료(S2)는 비균일한 두께(t)를 갖도록 가공된 상태로 제2 릴(150)에 회수될 수 있다. 이 때, 전술한 바와 같이, 제2 전도성 재료(S2)는 폭 방향으로 비균일한 두께를 가지고 있으므로 제2 릴(150) 상에 불규칙한 두께를 가지고 권취될 수 있다.Thereafter, the second conductive material S2 may be recovered to the second reel 150 in a processed state to have a non-uniform thickness t. At this time, as described above, since the second conductive material S2 has a non-uniform thickness in the width direction, it may be wound on the second reel 150 with an irregular thickness.
그 다음으로, 제2 릴(150)에 권취되어 있는 제2 전도성 재료(S2)는 다시 공급되면서 프레스부(140)를 통하여 프레싱 가공될 수 있다. 이를 통하여 버스 바(100)를 제조하기 위한 외형이 최종 결정될 수 있다.Next, the second conductive material S2 wound on the second reel 150 may be pressed through the press unit 140 while being supplied again. Through this, an outer shape for manufacturing the bus bar 100 may be finally determined.
경우에 따라서, 이러한 프레스 가공 진행 후, 배터리 단자와 연결될 수 있는 단자 연결부(미도시)에 도금처리 및 열처리 될 수 있다. 배터리 단자 연결부의 도금처리 및 열처리를 위해 그전에 마스킹(masking)이 포함될 수 있다. 마스킹을 위해 상기 단자 연결부 및 기 결정된 부분을 제외한 영역에 도금처리를 위한 마스크(미도시)가 도포될 수 있다. 도금처리 및 열처리를 위해 그전에 행하는 마스킹 처리는 상기 마스크 이외의 테이프(미도시)를 부착하는 방식으로 행할 수도 있다.In some cases, after such press working, the terminal connection part (not shown) that can be connected to the battery terminal may be plated and heat treated. For plating and heat treatment of the battery terminal connection part, masking may be included before that. For masking, a mask (not shown) for plating may be applied to an area excluding the terminal connection portion and a predetermined portion. The masking treatment performed before the plating treatment and heat treatment may be performed by attaching a tape (not shown) other than the above mask.
도금은 니켈(Ni), 금(Au), 구리(Cu) 및 주석(Sn) 중 적어도 하나의 금속으로 도금 될 수 있다. 도금은 전기 도금으로 진행될 수 있으며, 도금처리가 진행된 후, 금속판(10)에 도포된 상기 마스크 및 테이프는 제거될 수 있다.The plating may be performed with at least one of nickel (Ni), gold (Au), copper (Cu), and tin (Sn). Plating may be performed by electroplating, and after plating is performed, the mask and tape applied to the metal plate 10 may be removed.
상기와 같이 제조방법으로 제조된 버스 바는 가공시의 소성변형을 최소화하면서 얇은 두께의 제조가 가능할 뿐만 아니라, 가공 후에도 물성의 큰 변화 없이 높은 전기 전도성을 유지할 수 있다.The bus bar manufactured by the manufacturing method as described above can be manufactured with a thin thickness while minimizing plastic deformation during processing, and can maintain high electrical conductivity without significant change in physical properties even after processing.
나아가, 본 발명에 따른 버스 바 제조방법 및 이를 통해 제조되는 버스 바는 종래의 단조 방식에서 발생되는 문제점들을 해결할 수 있다. 즉, 종래에는 단조 공정을 적용하여 도전성 재료인 금속판재의 두께 대비 대략 30% 정도로만 가공이 가능하였으나 단조 공정을 제거하고 연삭 및 절삭을 통하여 상기 금속판재 두께의 상대적으로 더욱 얇게 제조할 수 있다. 즉, 본 발명에 따르면, 도전성 재료인 금속판재의 두께 대비 대략 70% 이하, 예를 들어 2T 이하의 두께를 갖도록 가공이 가능한 점에 특징이 있다. 이는 버스 바 제조 시에, 도 4 내지 도 5에 도시된 바와 같이, 소망하는 다양한 형상의 구현이 가능하도록 함으로써, 상기 금속판재의 폭 변경부에 대한 정밀도가 향상될 수 있다. 이는 종래의 단조 가공에서 발생되는 단차 부위의 만곡 되는 형상의 라운드 부위를 제거함으로써, 평탄도를 크게 향상시킬 수 있다.Furthermore, the method for manufacturing a bus bar according to the present invention and the bus bar manufactured through the method can solve problems occurring in the conventional forging method. That is, conventionally, the forging process was applied to process only about 30% of the thickness of the conductive material, compared to the thickness of the metal plate, but the forging process is eliminated and the metal plate can be manufactured to be relatively thinner than the thickness of the metal plate through grinding and cutting. That is, according to the present invention, it is characterized in that it can be processed to have a thickness of about 70% or less, for example, 2T or less, compared to the thickness of the metal plate, which is a conductive material. This makes it possible to implement various desired shapes when manufacturing the bus bar, as shown in FIGS. 4 to 5 , thereby improving the precision of the width change part of the metal plate material. This can greatly improve the flatness by removing the round portion of the curved shape of the step portion generated in the conventional forging process.
또한, 본 발명에 따른 제조방법은 종래의 대량으로만 생산이 가능한 단조 방식을 생략함으로써, 릴 투 릴 방식으로 대량 생산뿐만 아니라 소량 생산도 가능할 수 있다.In addition, the manufacturing method according to the present invention omits the conventional forging method that can only be produced in large quantities, so that not only mass production in a reel-to-reel method but also a small amount of production is possible.
이상, 본 발명에 따른 버스 바의 제조방법 및 이를 통해 제조된 버스 바, 및 릴의 일 실시예를 첨부된 도면을 참조하여 상세하게 설명하였다. 그러나, 본 발명의 실시예가 반드시 상술한 일 실시예에 의하여 한정되는 것은 아니고, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의한 다양한 변형 및 균등한 범위에서의 실시가 가능함은 당연하다고 할 것이다. 그러므로, 본 발명의 진정한 권리범위는 후술하는 청구범위에 의하여 정해진다고 할 것이다.In the above, an embodiment of a method for manufacturing a bus bar according to the present invention and a bus bar and a reel manufactured through the same have been described in detail with reference to the accompanying drawings. However, the embodiment of the present invention is not necessarily limited by the above-described embodiment, and it is natural that various modifications and implementations within an equivalent range are possible by those skilled in the art to which the present invention pertains. will be. Therefore, the true scope of the present invention will be determined by the claims to be described later.
