密気密に封口される。2. Description of the Related Art Conventionally, this type of sealed lead-acid battery has a structure as shown in FIG. In FIG. 3, reference numeral 1 denotes a frame made of polyolefin resin such as polypropylene, which houses therein an electrode plate group 6 consisting of a positive electrode plate 2, a negative electrode plate 3, and a separator 4. The opening of the frame 1 surrounding the electrode plate group 6 is sealed by heat welding the periphery of a metal plate 7 for a battery case, the inner surface of which is laminated with polyethylene quill or the like. Reference numeral 5 indicates a pole column portion, and reference numeral 10 indicates an exhaust valve provided in the frame 1 and having a function of opening when the internal pressure of the battery increases. The pole section 6 is sealed liquid-tightly by coating it with epoxy-based synthetic resin or polyethylene-based synthetic resin in advance and thermally welding it between the frame 1 and the metal plate 7.
発明が解決しようとする課題
しかし従来のような、鋳造によって極柱部を作る場合次
のような問題点かあ−た。Problems to be Solved by the Invention However, when the pole part is made by casting as in the past, the following problems arise.

の圧迫によりラミネートフィルムが溶けすぎて極柱部の
溶着強度に問題があった。(1) When pole columns are made by casting, there is a variation of ±0.1ff, so if the thickness of the pole column is the thinnest possible, the pole column can be made by heat welding between the frame and the metal plate. It was difficult to completely seal the seal, making it difficult to improve the yield of liquid-tightness. In addition, if the thickness of the pole column is thick, thermal welding may cause the melted frame resin to protrude to the outside of the battery, reducing the accuracy of battery dimensions, or the laminate film may melt too much due to the pressure of the pole. There was a problem with the welding strength of the poles.
＠）極柱部に鋳造の地肌の表面酸化層が残っていると極
柱腐食しやすく、極柱の腐食に対する信頼性にも問題が
あった。@) If the surface oxidation layer of the casting surface remains on the pole column, pole column corrosion is likely to occur, and there is also a problem with the reliability of the pole column against corrosion.
（３）極柱を鋳造によって作ると、以後の工程における
ハンドリング時の極柱のまがりや、折れ等による歩留り
に問題があった。(3) When pole columns are made by casting, there are problems with yield due to curling or bending of the pole columns during handling in subsequent steps.
本発明は、このような問題点を解消するものである。The present invention solves these problems.

ある。Means to Solve the Problem In order to solve this problem, the present invention has changed from the method of using the cast pole pole as it is, to casting the pole plate ear part to a large size in advance, and adjusting it to the desired thickness using a haiku machine or the like. Sharpen,
Furthermore, pole columns are made by punching out the desired width.

なくなり、電池寸法は安定し、さらに極柱部の溶着強度
も安定する。Function: (1) It is possible to improve the dimensional accuracy of the pole plate ears, improve the yield of liquid-tight airtightness during thermal welding when the pole pole is thin, and improve the yield of the frame resin when the pole is thick. There is no melting, the battery dimensions are stable, and the welding strength of the poles is also stable.
（２）極柱耳部を削って作ることにより、表面酸化層を
とり除いて金属鉛面を露出させることができ、極柱の腐
食に対する信頼性を向上できる。(2) By carving out the pole pole ears, the surface oxidation layer can be removed to expose the metal lead surface, and the reliability of the pole pole against corrosion can be improved.
倹）極柱部を大きく鋳造できることにより、これを削る
以前の工程における極柱部の強度は大きく、ハンドリン
グ時の極柱のまがりや折れ等による歩留りを向上できる
。(Saving) By being able to cast a large pole column, the strength of the pole column is high in the process before it is cut, and the yield can be improved due to curling or breaking of the pole column during handling.

This is a state after forming an ear portion 12' having a desired shape and size by cutting and punching from the state shown in FIG. For example, by cutting the ear portion 12 to a desired thickness and punching it to a desired width, the thickness is 0.7±○, the width is 2.6±0.05 f
The pole lugs 12' can be manufactured with an accuracy of f, and the yield for sealing the pole lugs when manufacturing the battery shown in FIG. 3 using the conventional pole lugs is 99.2%. On the other hand, when the electrode plate according to the present invention was used, the yield improved to 99.9%. In addition, when examining the degree of corrosion of the pole column by a trickle test of 7ot2.3V/cell for 10 days, it was found that in batteries using conventional pole ears, both the anode and cathode poles were 0.5.
However, in the battery using the electrode plate according to the present invention, the swelling could be suppressed to less than 0.1 ff. Furthermore, the yield rate due to the bending of pole pillars has been reduced from 99.5% to 9.
This improved to 9.9%.
