본 고안은 소형전해콘덴서에 삽입되는 전극리드단자의 화성(化成)장치에 관한 것으로, 특히 상.하로 대치된 서로 다른 극성을 지닌 자석 사이에서 형성되는 자력을 이용하여 리드단자를 간단하게 화성작업하기 위한 상태로 배열시켜, 화성공정의 안정화와 간소화 및 생산성 향상을 도모하도록 한 알루미늄박형 전해콘덴서용 전극리드단자의 화성장치에 관한 것이다.The present invention relates to a chemical conversion device of an electrode lead terminal inserted into a small electrolytic capacitor, and in particular, to easily convert a lead terminal by using a magnetic force formed between magnets having different polarities which are opposed to each other. The present invention relates to a chemical conversion device for electrode lead terminals for thin aluminum electrolytic capacitors, which is arranged in such a state as to stabilize and simplify the chemical conversion process and improve productivity.
일반적으로, 전해콘덴서는 제5도에 도시된 바와같이, 권취된 알루미늄전극박(61)과 접속된 1쌍의 리드단자(6)가 수직으로 돌출된 형상으로 되어, 상기 리드단자(6)를 통해 충.방전시키는 역할을 하는 것으로서, 상기 리드단자(6)는 제5도에 도시된 바와같이 리드선(cp선) ; (62)이 용접된 알루미늄봉(63)의 일부가 압착된 형상으로 이루어지고 철심 주위를 구리(Cu) 및 연질납(Sn+Pb)등이 둘러싸고 있어 자력을 가하면 자성을 띠도록 되어 있다.In general, as shown in FIG. 5, the electrolytic capacitor has a shape in which a pair of lead terminals 6 connected to the wound aluminum electrode foil 61 is formed to protrude vertically. As a function of charging and discharging through the lead terminal 6, the lead terminal 6 includes a lead wire (cp line); A portion of the aluminum rod 63 to which the 62 is welded is formed in a crimped shape, and copper (Cu) and soft lead (Sn + Pb) and the like are surrounded around the iron core.
이때, 리드단자는 화성작업을 거쳐 알루미늄봉 부위에 극히 얇은 산화피막을 형성시켜 누설전류를 감소시켜 주는 효과를 얻고 있다.At this time, the lead terminal has an effect of reducing the leakage current by forming an extremely thin oxide film on the aluminum rod portion through the chemical conversion work.
따라서, 상기한 효과를 얻기 위한 화성작업시 리드단자를 화성시키기에 적절한 상태로 하여주기 위해서는 리드단자를 효과적으로 배열할 수 있도록 한 화성장치 특히, 알루미늄봉 부위만을 전해액에 담그어 화성작업을 할 수 있도록 해주는 장치를 필요로 하게 되었다.Therefore, in order to bring the lead terminal into an appropriate state for converting the lead terminal in order to achieve the above-mentioned effect, a chemical conversion device for arranging the lead terminals effectively, in particular, so that only the aluminum rods can be immersed in the electrolyte solution. Needed a device.
그러나, 종래에는 제4도에 도시된 바와같이 양쪽측면에 일정한 간격으로 형성된 톱니를 갖춘 알루미늄 막대(41) 2개를 상하로 평행되도록 배열한뒤, 톱니막대(41) 사이에 자석띠(42)를 접착하여 이 자석띠(42)를 사이에 두고 상.하톱니(43)오목부에 안착되도록 리드단자(6)를 끼워주는 방식으로 삽입시키면 2개의 막대(41)사이에 접착된 자석띠(42)의 자력에 의해 자성체인 리드선이 상.하톱니(43)의 오목면에 접촉되어 부착되게 되고, 이렇게 부착된 리드단자의 높이를 일정하게 유지시키기 위한 방법으로 리드단자의 양쪽끝을 균일한 표면으로 된 금속판(도시되지 않음)으로 번갈아 한번씩 눌러주어, 일정한 높이로 수직정렬해 주도록 한 장치를 사용하였으나, 이러한 장치는 한정된 갯수의 톱니사이에만 리드단자를 끼워 줄 수 밖에 없으므로 단위면적단 리드단자(6)의 삽입수량(pcs/㎠)이 적어 생산성에 있어서 매우비현실적이로 또한, 삽입후 금속판으로 재정렬시켜주는 과정에서 리드단자(6)가 이탈되어 미화성품이 발생되고, 리드선의 변색으로 인한 외관불량 및 리드단자(6)의 접촉불량으로 인하여 발생되는 아아크열에 의한 화성장치의 손상과 같은 여러 문제점이 발생되고 있다.However, in the related art, as shown in FIG. 4, two aluminum rods 41 having teeth formed at regular intervals on both sides thereof are arranged in parallel to each other, and then the magnetic strip 42 is disposed between the tooth bars 41. FIG. The magnetic strip 42 is sandwiched between the upper and lower teeth 43 and the lead terminal 6 to be seated in the concave portion, and the magnetic strip bonded between the two rods 41 ( By the magnetic force of 42), the lead wire, which is a magnetic body, is brought into contact with the concave surface of the upper and lower teeth 43, and the both ends of the lead terminal are uniform in a manner to maintain the height of the lead terminal attached thereto. A device was used to alternately press vertically with a surface metal plate (not shown), and to vertically align it to a constant height. However, such a device can only lead lead terminals between a limited number of teeth. The insertion amount (pcs / cm 2) of the ruler 6 is very unrealistic in productivity, and in the process of realigning to the metal plate after insertion, the lead terminal 6 is detached to generate a non-chemical product, resulting in discoloration of the lead wire. Various problems such as damage to the chemical conversion apparatus due to arc heat generated due to poor appearance and poor contact of the lead terminal 6 are caused.
한편, 최근에는 미화성품의 발생을 줄이고 특히 생산성을 높이기 위한 방법의 하나로써, 이송벨트 윗면에 전자석을 부착시키고 리드단자를 제작하기 전에 알루미늄봉 부위를 1차화성한뒤 이 화성처리된 알루미늄봉과 리드선을 용접한 다음 알루미늄 봉을 프레스 가공하고, 프레스된 부분을 재화성시키는 방법이 이용되고 있기는 하나, 이 장치에 있어서도, 알루미늄 봉을 재화성하기 위한 많은 어려움이 따르며 상기한 방법 역시, 리드단자의 이탈 및 리드선부위의 변색을 방하지는 못하고 있는 실정이다.On the other hand, in recent years, as one of the methods for reducing the occurrence of unburned products and increasing productivity, the aluminum rods and lead wires which have been chemically treated after attaching an electromagnet to the upper surface of the transfer belt and forming the lead terminal firstly Although the method of welding the aluminum rod and then press-processing the aluminum rod and rebuilding the pressed portion is used, this apparatus also has many difficulties for rebuilding the aluminum rod. It is not possible to prevent the departure and discoloration of the lead wire portion.
이에 본 고안에 상기한 바와의 문제점을 해결하기 위하여 안출된 것으로, 서로 다른 극성을 갖는 자석판을 소정의 간격을 두고 상.하로 대치시켜 이들자석판사이에 형성되는 자장의 자력을 이용하여 리드단자를 간단하게 화성작업하기 위한 상태로 수직배열시켜 줌으로써, 설비의 오동작을 방지하도고 공정의 간소화 및 설비의 자동화를 통한 생산성향상을 이루도록 한 화성장치를 제공함에 그 목적이 있다.In order to solve the problems as described above in the present invention, the lead terminal by using the magnetic force of the magnetic field formed between these magnetic plates by simply replacing the magnetic plates having different polarity up and down at a predetermined interval. By vertically arranging in a state for working with Mars, the purpose of the present invention is to provide a Mars apparatus that prevents a malfunction of a facility and improves productivity by simplifying a process and automating a facility.
상기와 같은 목적을 달성하기 위한 본 고안은 손잡이가 설치된 상부지지판이 하부지지판과 소정의 간격을 두고 배열설치되고, 상기 상.하부지지판의 서로 대칭하는 안쪽면 각각에 양극중의 한쪽극만을 갖도록 된 자석판이 각각 부착되어, 이들 양쪽 상.하자석판 사이에 자장이 수직방향으로 형성되도록 한 구조로 되어 있다.The present invention for achieving the above object is that the upper support plate is installed with a handle is arranged at a predetermined interval with the lower support plate, to have only one pole of the positive electrode on each of the inner surface symmetrical of the upper and lower support plates The magnetic plates are attached to each other so that a magnetic field is formed in the vertical direction between the upper and lower magnetic plates.
이러한 구조로 된 본 고안 화성장치의 양쪽 상.하부지지판 사이로 리드선을 일정방향으로 넣어 주기만 하면, 상.하자석판의 자장을 따라 리드선이 배열되면서 윗쪽 자석판에 수직으로 매달리도록 되어 있다. 따라서 아랫쪽으로 향한 리드단자의 알루미늄봉 부위가 전해조에 잠기게 한 상태로 화성작업을 할 수가 있다.The lead wires are arranged in a predetermined direction between both upper and lower support plates of the present invention apparatus having such a structure, and the lead wires are arranged perpendicularly to the upper magnetic plate while the lead wires are arranged along the magnetic field of the upper and lower magnetic plates. Therefore, it is possible to perform the work of Mars with the aluminum rod part of the lead terminal facing downward locked in the electrolytic cell.
상기한 바와같은 방법에 따라, 서로 다른 극성을 지닌 자석판 사이에 형성되는 자력선을 따라, 일정한 간격과 높이로 수직배열된 리드단자를 화성액이 단기 전해조에 잠기게 하여 화성작업을 함으로써, 별도로 리드단자를 재정렬해줄 필요가 없고, 리드단자의 이탈로인한 리드선의 변색과 같은 결점이 제거가 가능해져 화성공정의 간소화와 자동화로 관리의 효율화에 기여함으로서, 생산성 향상의 효과가 매우 크다.According to the method as described above, the lead terminals vertically arranged at regular intervals and heights along the lines of magnetic force formed between the magnetic plates having different polarities are separated by the chemical conversion work so that the chemical liquid is submerged in the short-term electrolytic cell, There is no need to rearrange the wires, and defects such as discoloration of the lead wires due to the lead terminals can be eliminated, thereby contributing to the efficiency of management by simplifying and automating the chemical conversion process.
이하 본 고안을 첨부되 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.1 is described in detail based on the accompanying drawings of the present invention.
제1도는 본 고안에 제1실시예에 따른 화성장치의 사시도로서, 직사각 형상의 상부지지판(1)에 한쪽 전극을 띤 자석판(2a)이 내장되고, 이 상부지지판(1)은 소정의 간격을 두고 한쪽전극을 띤 또다른 자석판(2b)이 부착된 하부지지판(3)과 보울트(도시되지 않음)등으로 되어 있다.1 is a perspective view of a chemical conversion apparatus according to a first embodiment of the present invention, in which a rectangular upper support plate 1 includes a magnet plate 2a having one electrode, and the upper support plate 1 has a predetermined interval. It is composed of a lower support plate 3 and a bolt (not shown) attached with another magnet plate 2b having one electrode.
여기에서, 상기 상부지지판(1)의 아랫면 중앙부에는 하부지지판(3)과 마주보도록 설치된 한쪽전극을 띠 자석판(2a)이 홈안에 삽입되어 스테인레스(5)으로 덮어져 하부지지판(3)과 대향하도록 설치되어 있고 또한, 이 상부지지판(1)은 테이프론으로 된 4개의 절연봉(4)을 사이에 두고 윗면에 한쪽전극을 띤 또다른 자석판(2b)이 삽입되어 스테인레스판(5)으로 덮어져 설치된 하부지지판(3)과 보울트(도시되지 않음)등으로 체결되어 있다. 한편, 상기 상부지지판(1)의 양쪽에는 손잡이(7)가 보울트(도시되지 않음)등으로 체결되어 있다.Here, one electrode installed to face the lower support plate 3 is disposed at the center of the lower surface of the upper support plate 1 so that the strip magnet plate 2a is inserted into the groove and covered with the stainless steel 5 so as to face the lower support plate 3. The upper support plate 1 is provided with another magnetic plate 2b having one electrode on the upper surface with four insulating rods 4 made of taperons interposed therebetween and covered with a stainless plate 5. The lower support plate 3 and the bolt (not shown) are installed. On the other hand, the handle 7 is fastened by bolts (not shown) or the like on both sides of the upper support plate (1).
그리고, 상기 상.하부 자석판(2a,2b)은 상부지지판(1)과 하부지지판(3) 사이에서 서로 마주보며 대향되도록 설치되어 있어, 각 자석판(2a,Sb)이 상.하로 대치되는 사이에서 일정한 자장이 수직방향으로 형성되도록 되어 있다. 여기서, 대응하는 자력선에 의한 리드단자(6)의 정렬간격은 유지되어 매달리는 힘은 자력 또는 상.하로 대치되는 두자석판(2a,2b)의 간격에 의해 결정되는데, 제1실시예의 경우, 리드단자(6)의 공급 정렬수량은 실험에 의하여 3~30pcs/㎠가 적당하다.The upper and lower magnetic plates 2a and 2b are disposed to face each other between the upper support plate 1 and the lower support plate 3 so that the respective magnet plates 2a and Sb are opposed to each other up and down. A constant magnetic field is formed in the vertical direction. Here, the alignment interval of the lead terminal 6 by the corresponding magnetic force line is maintained and the hanging force is determined by the magnetic force or the distance between the two magnetic plates 2a and 2b which are replaced up and down, in the case of the first embodiment, the lead terminal (6) The number of feed sorting quantity is 3 ~ 30pcs / ㎠ by experiment.
한편, 제2실시예에 따른 화성장치는 제2도의 도시되 바화 같이 상기한 1실시예와는 달리, 상기 상부지지판(1)과 하부지지판(3)에 다수개의 자석판(2c,2d)을 각 극성이 서로 대향되도록 수평으로 배치하여 줌으로써, 자석의 경계에서 형성되는 좀 더 큰 자력으로 많은 리드단자(6)을 자동정렬해 줄 수 있도록 되어 있는데 이 실시예의 경우, 리드단자(6)의 삽입수량은 3~30pcs/㎤가 최적수준이다.On the other hand, unlike the above-described one embodiment, as shown in FIG. 2, the growth growth value according to the second embodiment is a plurality of magnet plates 2c and 2d on the upper support plate 1 and the lower support plate 3, respectively. By arranging the polarities horizontally so as to face each other, it is possible to automatically align many lead terminals 6 with a larger magnetic force formed at the boundary of the magnet. In this embodiment, the amount of insertion of the lead terminals 6 is The optimum level is 3 ~ 30pcs / cm3.
따라서, 상기한 실시예에 따라 화성장치의 상.하부 지지판(1,3)에서 서로 마주보도록 설치된 상.하자석판(2a,2b)사이로 리드선을 일정방향으로 넣어주게 되면, 각 자석판(2a,2b)사이에 수직방향으로 형성되는 자력에 의해 리드단자(6)가 일정한 간격과 일정한 높이로 자동배열이 되면서 상부지지판(1)에 부착된 자석(2a)에 수직으로 매달리게 되고 이렇게 리드단자(6)가 수직으로 매달려 있는 화성장치를 전해조(9)에 담궈주기만 하면, 제3도에 도시된 바와같이 아래쪽으로 향한 리드단자의 알루미늄봉부위가 전해액(8)에 잠기게 되어 화상작업이 이루어지도록 되어 있는데 이때, 전해조(9)에 담긴 전해액(8)의 양을 상기 화성장치에 매달린 리드단자(6)의 알루미늄봉(cp 선이하)부위까가지만 잠기게 되도록 적당량의 전해액(8)을 채워주어 화성작업시 리드선이 전해액(8)에 담궈지는 것을 방지하도록 하는 것이 중요하다.Therefore, when the lead wire is put in a predetermined direction between the upper and lower magnetic plates 2a and 2b installed to face each other in the upper and lower support plates 1 and 3 of the chemical conversion apparatus, the respective magnetic plates 2a and 2b. By the magnetic force formed in the vertical direction between the lead terminal 6 is automatically arranged at a constant interval and a constant height while being suspended vertically to the magnet (2a) attached to the upper support plate (1) and thus the lead terminal (6) If you just immerse the vertically suspended chemical apparatus in the electrolytic cell 9, as shown in FIG. 3, the aluminum rod portion of the lead terminal facing downward is immersed in the electrolytic solution 8 to perform the image work. At this time, the amount of the electrolyte (8) contained in the electrolytic cell (9) is filled with an appropriate amount of the electrolyte (8) so as to be locked only to the aluminum rod (less than cp line) of the lead terminal (6) suspended on the chemical conversion device Lead wire delivered It is important to prevent immersion in the liquid (8).
따라서, 본 고안에 따른 화성장치를 사용함으로써 리드단자의 배열방법을 개선하여 줌과 동시에, 설비의 오동작을 방지 하여 주는 한편, 리드선의 변색으로 인한 외관불량을 방지할 수 있다.Therefore, by using the chemical conversion apparatus according to the present invention, it is possible to improve the arrangement method of the lead terminals, to prevent malfunction of the equipment, and to prevent appearance defects due to discoloration of the lead wires.
이상에서 설명한 바와 같이 본 고안에 따른 알루미늄박형 전해 콘덴서용 전극리드단자의 화상장치는 리드단자의 이탈을 방지하고 리드단자의 배열을 효율적인 방법으로 하게 됨으로써, 화성공정을 간소화 시킬 수 있게 해주어, 생산성 향상에 기여함을 물론, 관리의 효율화 및 리드단자의 생산원가를 절감할 수 있는 효과가 있다.As described above, the imaging device of the electrode lead terminal for the aluminum thin electrolytic capacitor according to the present invention prevents the detachment of the lead terminal and arranges the lead terminals in an efficient manner, thereby simplifying the chemical conversion process, thereby improving productivity. Of course, the efficiency of the management and the lead cost of the lead terminal can be reduced.
