Description
この発明は、積層型電気二重層キャパシタのアルミラミネートフィルム熱溶着装置に関するものである。 The present invention relates to an aluminum laminate film heat welding apparatus for a multilayer electric double layer capacitor.
図２は特許文献１に示された従来の積層型電気二重層キャパシタ本体8の断面図を示し、活性炭電極を接着した２枚の集電極板１の間に、アルミ箔基材２ａの両面に活性炭電極２ｂを接着した中間電極２とイオンが移動可能なセパレータ３とを交互に重ねて挟み込み、中間電極２及びセパレータ３の外周には内部の電解液等が漏れないように、また中間電極２間を絶縁するためにシール機能を有するゴムパッキン４を設けている。又、集電極板１の外面側には加圧板５を設け、絶縁スペーサ６を介してボルト７で締め付けることにより、密閉構造で加圧力を加えた構造としている。 FIG. 2 is a cross-sectional view of a conventional multilayer electric double layer capacitor body 8 disclosed in Patent Document 1, and is disposed on both surfaces of an aluminum foil base 2a between two collector plates 1 to which activated carbon electrodes are bonded. The intermediate electrode 2 to which the activated carbon electrode 2b is bonded and the separator 3 to which ions can move are alternately stacked and sandwiched so that the inner electrolyte 2 and the separator 3 do not leak to the outer periphery, and the intermediate electrode 2 A rubber packing 4 having a sealing function is provided to insulate the gap. Further, a pressure plate 5 is provided on the outer surface side of the collector electrode plate 1 and is tightened with a bolt 7 via an insulating spacer 6 so that pressure is applied in a sealed structure.
図３（ａ），（ｂ）は従来の積層型電気二重層キャパシタ本体８の平面図及び正面図を示し、実際には集電極板１には一対の集電端子９が突出して設けられている。又、図４（ａ），（ｂ）に示すように、キャパシタ本体８は外気遮断のためにアルミラミネートフィルム１０により包装され、アルミラミネートフィルム１０の内部は真空引きされ、集電端子９はアルミラミネートフィルム１０の端部と熱溶着される。なお、積層型電気二重層キャパシタ本体８は実際には見えない。
図５はキャパシタ本体８の一部拡大図を示し、メンテナンス性の向上から集電端子９は集電極板１とは別の部品で構成され、集電端子９の一部は集電極板１と加圧板５との間に挿入される。しかし、このように、別々の部品としたことによって、キャパシタ本体８の組立段階において、集電端子９の間隔が多少ずれたまま組み立てられてしまうことがある。 FIG. 5 shows a partially enlarged view of the capacitor main body 8, and the collector terminal 9 is constituted by a part different from the collector electrode plate 1 for improvement of maintainability, and a part of the collector terminal 9 is part of the collector electrode plate 1. It is inserted between the pressure plate 5. However, by using separate components as described above, the assembly of the capacitor body 8 may be assembled with the gap between the current collecting terminals 9 slightly deviated.
一方、図６及び図７は積層型電気二重層キャパシタのアルミラミネートフィルム熱溶着装置における真空包装用熱溶着器による熱溶着の様子を示す斜視図及び集電端子と下側圧着板との関係を示す説明図を示し、熱溶着器１１は鉄製の上側圧着板１２と下側圧着板１３とを有し、約１９０℃に加熱された一対の圧着板１２，１３によりアルミラミネートフィルム１０の端部は５気圧の圧力で圧着される。この際、アルミラミネートフィルム１０が集電端子９によって損傷しないように、下側圧着板１３には集電端子９を収納するための集電端子収納溝１３ａ，１３ｂが集電端子９の厚さに合わせた深さで一対設けられており、集電端子９の位置ずれに対応するために集電端子収納溝１３ａ，１３ｂの幅に裕度を持たせて集電端子９の幅より若干広めにしているが、集電端子９の間隔のずれが大きいと、集電端子９は集電端子収納溝１３ａ，１３ｂに収まったとしても、アルミラミネートフィルム１０と集電端子９との間に隙間が生じてシール不良を起こすことがある。 On the other hand, FIGS. 6 and 7 are perspective views showing the state of heat welding by a vacuum packaging heat welder in an aluminum laminate film heat welding apparatus of a multilayer electric double layer capacitor, and the relationship between the current collector terminal and the lower crimping plate. The thermal welder 11 has an iron upper crimping plate 12 and a lower crimping plate 13, and an end portion of the aluminum laminate film 10 by a pair of crimping plates 12 and 13 heated to about 190 ° C. Is pressure-bonded at a pressure of 5 atm. At this time, in order to prevent the aluminum laminated film 10 from being damaged by the current collecting terminal 9, current collecting terminal housing grooves 13 a and 13 b for housing the current collecting terminal 9 are formed in the lower crimping plate 13. A pair with a depth corresponding to the current collector terminal 9 is provided, and the width of the current collector terminal receiving grooves 13a and 13b is given a margin to be slightly wider than the width of the current collector terminal 9 in order to cope with the displacement of the current collector terminal 9. However, if the gap between the current collecting terminals 9 is large, the gap between the aluminum laminated film 10 and the current collecting terminals 9 is not reduced even if the current collecting terminals 9 are accommodated in the current collecting terminal receiving grooves 13a and 13b. May cause seal failure.
そのため、従来では、図８に示すように、下側圧着板１３の長さを半分にし、集電端子収納溝１３ａも一つだけとして、1回目の溶着作業では一方の集電端子９を含む半分のアルミラミネートフィルム１０の端部の溶着を行い、２回目の溶着作業では他方の集電端子９を含む残り半分のアルミラミネートフィルム１０の端部の溶着を行い、溶着を確実に行うようにしていたが、溶着作業が二度手間となるという欠点があった。 Therefore, conventionally, as shown in FIG. 8, the length of the lower pressure-bonding plate 13 is halved, the current collecting terminal receiving groove 13a is only one, and one current collecting terminal 9 is included in the first welding operation. The end of the half aluminum laminate film 10 is welded, and in the second welding operation, the end of the other half of the aluminum laminate film 10 including the other current collecting terminal 9 is welded to ensure the welding. However, there was a drawback that the welding work was troublesome twice.
この発明は上記のような課題を解決するために成されたものであり、１回の溶着作業でアルミラミネートフィルムと集電端子との溶着をシール不良を生じることなく確実に行うことができる積層型電気二重層キャパシタのアルミラミネートフィルム溶着装置を得ることを目的とする。 The present invention has been made to solve the above-described problems, and is a laminate that can reliably perform welding between an aluminum laminate film and a current collecting terminal without causing a sealing failure in one welding operation.

実施最良形態１
以下、この発明を実施するための最良の形態を図面とともに説明する。図１はこの発明の実施最良形態１による積層型電気二重層キャパシタのアルミラミネートフィルム熱溶着装置における真空包装用熱溶着器の熱溶着の説明図であり、溶着器１１の鉄製の下側圧着板１４を長さ方向に２分割して分割部分１４ａ，１４ｂとし、その間にシリコンゴムからなる弾性材１５を挟んで一体化して下側圧着板１６を形成する。下側圧着板１６においては、弾性材１５の両側で集電端子９の幅とほぼ同じ幅で集電端子９の厚さとほぼ同じ深さの集電端子収納溝１６ａ，１６ｂを集電端子９の間隔より広い間隔で一対設ける。
Best Embodiment 1
The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view of heat welding of a heat-sealing device for vacuum packaging in an aluminum laminate film heat-welding device for a multilayer electric double layer capacitor according to Embodiment 1 of the present invention. 14 is divided into two parts 14a and 14b in the length direction, and an elastic material 15 made of silicon rubber is sandwiched between them to form a lower pressure-bonding plate 16. In the lower crimping plate 16, the current collecting terminal receiving grooves 16 a and 16 b having the same width as the current collecting terminal 9 and the same depth as the current collecting terminal 9 are formed on both sides of the elastic material 15. A pair is provided with an interval wider than the interval.
溶着に際しては、下側圧着板１６を長さ方向に圧縮して集電端子収納溝１６ａ，１６ｂの間隔を集電端子９の間隔と一致させ、集電端子９を集電端子収納溝１６ａ，１６ｂに収納し、アルミラミネートフィルム１０の端部及び集電端子９を上側圧着板１２と下側圧着板１６とにより挟んで加熱圧着して溶着する。 At the time of welding, the lower crimping plate 16 is compressed in the length direction so that the distance between the current collecting terminal receiving grooves 16a and 16b is equal to the distance between the current collecting terminals 9, and the current collecting terminal 9 is connected to the current collecting terminal receiving grooves 16a, 16b, the end of the aluminum laminate film 10 and the current collecting terminal 9 are sandwiched between the upper pressure-bonding plate 12 and the lower pressure-bonding plate 16, and are heat-pressed and welded.
実施最良形態１においては、下側圧着板１４を長さ方向に２分割し、間にシリコンゴムからなる弾性材１５を介して一体化して下側圧着板１６を形成しており、アルミラミネートフィルム１０の端部及び集電端子９を圧着する際に、集電端子９の間隔が集電端子収納溝１６ａ，１６ｂの間隔とずれていても、下側圧着板１６を長さ方向に圧縮することにより集電端子収納溝１６ａ，１６ｂの間隔を集電端子９の間隔に合わせることができる。このため、１回の溶着作業で集電端子９等の溶着をシール不良を生じることなく、確実に行うことができる。 In the first embodiment, the lower pressure-bonding plate 14 is divided into two in the length direction, and the lower pressure-bonding plate 16 is formed integrally with an elastic material 15 made of silicon rubber therebetween. When the end portion of 10 and the current collecting terminal 9 are crimped, the lower pressure-bonding plate 16 is compressed in the length direction even if the distance between the current collecting terminals 9 is shifted from the distance between the current collecting terminal housing grooves 16a and 16b. Thus, the interval between the current collecting terminal housing grooves 16 a and 16 b can be adjusted to the distance between the current collecting terminals 9. For this reason, welding of the current collector terminals 9 and the like can be reliably performed without causing a sealing failure in one welding operation.

Embodiment 2
In the first embodiment, silicon rubber is used as the elastic material 15, but in the second embodiment, fluorine rubber is used as the elastic material 15. Fluororubber has a higher elastic modulus than silicon rubber, and the change in the interval between the current collecting terminal receiving grooves 16a and 16b when compressed in the length direction is large. For this reason, even when the gap | interval gap | deviation of the current collection terminal 9 is large, it can respond flexibly. In addition, the same effects as in the first embodiment are obtained.
