【発明の詳細な説明】
本発明は鉛蓄電池用格子体の製造法の改良に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved method for manufacturing a grid for lead-acid batteries.
近年鉛蓄電池を軽量化する目的で、合成樹脂基体の研究
がなされているが、実用化には至っていない。In recent years, research has been conducted on synthetic resin bases for the purpose of reducing the weight of lead-acid batteries, but this has not yet been put to practical use.
この原因の一つとして、合成樹脂基体に導電性を保持せ
しめる技術の開発が完成されていないことが挙げられる
。One of the reasons for this is that the development of technology for making synthetic resin substrates maintain electrical conductivity has not been completed.
従来合成樹脂基体に導電性を保持せしめるには、合成樹
脂基体鉛格子体を重ねて熱溶着して一体化する方法、あ
るいは合成樹脂基体に鉛をコーティングする方法等を採
用していた。Conventionally, in order to maintain electrical conductivity in a synthetic resin base, methods such as stacking synthetic resin base lead lattice bodies and thermally welding them into one body, or coating the synthetic resin base with lead, etc. have been adopted.
然し乍ら、前者にかいては多くの工数を要するにも拘わ
らず、従来の鉛合金格子体に比べて差程軽くはならない
。However, although the former method requires many man-hours, it is not significantly lighter than a conventional lead alloy grid.
また後者においてはコーディング部を厚くできないため
電気抵抗が大で 且つ使用するに伴なって合成樹脂基体
とコーティング部分が剥離するため一層電気抵抗が欠点
を有していた。In the latter case, the coating part cannot be thickened, so the electrical resistance is high, and the coating part peels off from the synthetic resin base as it is used, so the electrical resistance is even more disadvantageous.
本発明は上記の如き欠点を除去するもので、電気抵抗が
小さく、且つ使用後にむいても電気抵抗が増加しない鉛
蓄電池用基１本の製造方法を提供するものである。The present invention eliminates the above-mentioned drawbacks and provides a method for manufacturing a lead-acid battery base that has low electrical resistance and does not increase in electrical resistance even when peeled off after use.
本発明の一実施例を説明する。An embodiment of the present invention will be described.
合成樹脂格子体１を射出成形等により作製し、合成樹脂
格子体１よりやや大なる寸法を有する。The synthetic resin lattice body 1 is produced by injection molding or the like, and has dimensions slightly larger than the synthetic resin lattice body 1.
鉛または鉛合金からなる薄板２の１す目が、合成樹脂格
子体１の１す目の中央部に位置するようにして合成樹脂
格子体１を薄板２で挾み、両側から２枚の金形３で加圧
する。Sandwich the synthetic resin lattice body 1 between the thin plates 2 so that the first corner of the thin plate 2 made of lead or lead alloy is located in the center of the first corner of the synthetic resin lattice body 1. Apply pressure using Type 3.
金形３は合成樹脂格子体１が十分大る余裕をもった溝４
′ｉ、＝よび電極５を有している。The mold 3 has a groove 4 in which the synthetic resin lattice body 1 has a sufficiently large margin.
'i, = and an electrode 5.
かくして２枚の薄板２により合成樹脂格子体１は完全に
包み込まれるようになる。In this way, the synthetic resin lattice body 1 is completely enveloped by the two thin plates 2.
包み込んだ２枚の薄板２の重なるところは電極５によっ
て圧着されているので、次に電極５を通して、大電流を
短時間流し、その時生ずる発熱によって、２枚の薄板２
を溶接し、合成樹脂格子体１に固着させて電導性を保持
せしめる。The overlapping parts of the two wrapped thin plates 2 are crimped by the electrodes 5, so next, a large current is passed through the electrodes 5 for a short time, and the heat generated at that time causes the two thin plates 2 to overlap.
are welded and fixed to the synthetic resin grid body 1 to maintain electrical conductivity.
上記の如くして得られた格子体は、コーティングにより
電導性を保持せしめた従来の格子体に比べて、電気抵抗
は約１７３に減少し、かつ２枚の薄板２との密着強度が
きわめて強いために、従来のコーティングにより電導性
を保持せしめた格子体のように、使用中にむいてコーテ
ィング部と合成樹脂部が剥離し、電気抵抗が増加する現
象は全くなくなった。The lattice body obtained as described above has an electrical resistance reduced to about 173 compared to a conventional lattice body whose conductivity is maintained by coating, and has extremely strong adhesion strength to the two thin plates 2. Therefore, there is no longer a phenomenon in which the coated part and the synthetic resin part peel off during use, causing an increase in electrical resistance, unlike in conventional grid bodies that maintain electrical conductivity through coating.
また薄板２の重合部は、第４図に示す如く、格子の中央
部の突起として残存するのするので、−ペーストを充填
しても、従来の鉛合金格子体や合成樹脂格子体に比べて
極めて落ち難く、充填作業やその後の作業が非常に容易
である。In addition, the overlapping portion of the thin plates 2 remains as a protrusion at the center of the grid, as shown in Fig. 4, so even if the paste is filled, the overlapping part of the thin plate 2 remains as a protrusion in the center of the grid, so even if the paste is filled, the overlap will be smaller than that of the conventional lead alloy grid or synthetic resin grid. It is extremely difficult to fall off, making filling work and subsequent work very easy.
上述せる如く、本発明によれば、製造が容易であり、捷
た電気抵抗が小さく、さらにペーストの脱落を防止する
ことができる等工業的価値甚だ大なるものである。As described above, the present invention has great industrial value, such as ease of manufacture, low electrical resistance due to cracking, and ability to prevent paste from falling off.
