Description

【発明の詳細な説明】 産業上の利用分野 本発明は、溶融鉛により極板耳と一体にストラップ及び
極柱を融着するいわゆるキャストオン法に係る鉛蓄電池
用極板群の製造方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a lead-acid battery electrode plate group according to a so-called cast-on method in which a strap and a pole are integrally fused with a plate ear by molten lead.

従来の技術 従来、キャストオン法によるストラップの形成は、次の
ような手順で行なわれていた。2. Description of the Related Art Conventionally, formation of a strap by the cast-on method has been performed by the following procedure.

まず、極板耳が所定の長さに切断され、極板耳部の先端

る。First, the electrode plate ears are cut to a predetermined length, the tip of the electrode plate ears are polished with a brush, etc., and then the anode plate, the cathode plate and the separator are stacked (stacking) to form a single cell. , Flux is applied to the tip of the electrode plate ear.

その後、ストラップと極柱を型取った鋳型内の所定の位

させてストラップとしている。After that, after holding the electrode plate ears at a predetermined position in the mold obtained by molding the strap and the pole, molten lead is injected and cooled and solidified to form a strap.

なわち、極端な場合には、ある極板の耳は溶け落ちそう

っているだけになるという欠点があった。Problems to be Solved by the Invention However, even within the same strap, due to the position from the inlet, the degree of adhesion of lead oxide, etc., the structure of the mold, etc., the fused state of the ears of each electrode plate becomes uneven. There was a tendency. That is, in an extreme case, there is a drawback in that the ears of one electrode plate are likely to melt down, while the ears of another electrode plate are barely fused and only covered with lead.

本発明は上記欠点を除去することを目的とするものであ
る。The present invention aims to eliminate the above-mentioned drawbacks.

問題点を解決するための手段 本発明は上記目的を達成するために、極板の耳の中間部

融鉛液面付近に位置させることにより、融着状態を均一
かつ良好にするものである。Means for Solving the Problems In order to achieve the above object, the present invention has a portion thicker than the thickness of the electrode plate lattice in the middle portion of the ears of the electrode plate, and the thick portion is located near the molten lead liquid level. This makes the fused state uniform and good.

作用 従来のキャストオン法では、前述のように、融着状態が
不均一になる傾向がある。これは、換言すると、鋳型・
溶融鉛などの温度条件が厳しいために、低すぎると融着
せず、高すぎると溶断してしまうということである。
又、電池の軽量化に伴なって格子も薄くなってきている
ため、温度条件はさらに厳しくなってきている。Function In the conventional cast-on method, the fused state tends to be non-uniform as described above. In other words, this is the mold
Since the temperature conditions of molten lead and the like are severe, if it is too low, it will not fuse, and if it is too high, it will melt.
In addition, the temperature condition has become more severe because the lattice has become thinner as the battery has become lighter.

本発明によれば、格子の耳の中間部が厚いため、溶融鉛
の液面付近で融着の際の溶け代をより大きく見積ること
ができる。従って、最適温度条件からのズレが吸収さ
れ、耳が溶けて切れることなく確実な融着が行なわれ
る。According to the present invention, since the middle portion of the ears of the lattice is thick, it is possible to further estimate the melting margin at the time of fusion in the vicinity of the liquid surface of the molten lead. Therefore, the deviation from the optimum temperature condition is absorbed, and the ears melt and the fusion is surely performed without being cut.

実施例 本発明の一実施例を説明する。Example An example of the present invention will be described.

る。A pole plate having a portion 4 thicker than the thickness of the pole plate grid 3 is used in the middle portion of the pole 1 of the pole plate, the ear 1 is inserted into the mold 3, molten lead is injected into the mold 3, and the strap 2 is integrated with the ear 1. Is formed.

（ａ）は耳１の先端が極板格子３の厚みより薄い極板、
（ｂ）は耳１の先端が極板格子３の厚みと同等の極板を
示している。(A) is an electrode plate in which the tip of the ear 1 is thinner than the thickness of the electrode plate grid 3,
(B) shows a pole plate in which the tip of the ear 1 has the same thickness as the pole plate grid 3.

る。As described above, according to the present invention, by thickening the middle part of the ears of the electrode plate, the electrode plate ears and the strap are prevented by melting down the base part of the ear strap when coming into contact with molten lead. A method for manufacturing a battery electrode plate group that ensures fusion with
It is also possible to support the thinning of the grid, which is expected to continue in the future.

防止されるなどの効果がある。Another completely different effect is that the plate ripening can be efficiently controlled. That is, usually, the electrode plate aging is carried out by closely adhering a large number of electrode plates, but since the electrode plate of the present invention cannot be completely adhered, oxygen is smoothly supplied (aged for a short time). Further, there is an effect that an excessive temperature rise (production of tetrabasic lead sulfate which causes a decrease in utilization rate of active material) is prevented.
