た。Conventionally, the method of chemically forming electrode plates for lead-acid batteries has been to alternately use unformed negative and anode plates and maintain appropriate spacing so that adjacent negative and anode plates do not touch each other, and to form an acid-resistant chemical compound filled with dilute sulfuric acid. After inserting it into the tank, welding connecting lead alloy bars for energization to the respective ears of the negative and anode plates for energizing chemical conversion, or a metal feeding method having a groove in the bottom of the acid-resistant chemical conversion tank. After providing a gold connecting conductor and filling it with dilute sulfuric acid, insert the unformed negative and anode plates into the groove alternately and maintaining appropriate intervals so that adjacent negative and anode plates do not come into contact with each other. A method was adopted in which a connecting conductor and a current-carrying circuit were formed and chemical formation was performed. However, the above method has three points: ■ inserting the unformed negative and anode plates into the chemical conversion tank alternately at appropriate intervals, ■ connecting the connecting part and the ears of the electrode plates by welding, Manual work is required to insert the anode plates alternately into the grooves of the connecting conductors at the bottom of the chemical conversion tank, and to pull up the negative and anode plates after chemical formation has been completed so as not to burn them out. This was a major obstacle in automating the process.
本発明は上記の欠点を解消して、化成工程を完全自動化
したものであり、以下一実施例により詳細に説明する。The present invention eliminates the above-mentioned drawbacks and completely automates the chemical conversion process, and will be explained in detail below using an example.

必要な機械的強度を充分備えているのみならず、一般の
10〜20時間程度の短い化成時間では溶着不充分のた
めに溶着部が腐食して破壊することはない。As described above, in the present invention, the ears of the negative and 5M electrode plates are connected by cast-on welding, so the spacing between the ears of the negative and anode plates may vary during stacking, and the tips of the ears may Even if the height varies slightly, it is not a problem because the molten lead that serves as the current-carrying part melts the ears, so the stacking process can be easily automated. In addition, even if an oxide film adheres to the ear and makes it difficult to weld, at least the ear is wrapped in the current-carrying part, so if it has sufficient mechanical strength necessary for handling the electrode plate group, First, the welded portion will not corrode and be destroyed due to insufficient welding during the short chemical formation time, which is generally about 10 to 20 hours.
また、耳部とキャストオン溶接部とは機械的に竪固に結

ることができる。In addition, since the ear part and the cast-on welding part are mechanically and rigidly connected, the entire electrode plate group can be carried in suspension by grasping an appropriate part of the cast-on welding part. It becomes possible to mechanically insert the group into the chemical conversion tank and to pull up the electrode plate group after chemical conversion from the chemical conversion tank without short-circuiting the negative and anode plates, and the transportation process can be automated.

かった接続不充分による化成不良を解消することができ
る。Furthermore, the contact between the cast-on weld at the bottom of the electrode plate group and the protruding part of the acid-resistant conductive connector is ensured at several points due to the weight of the electrode group, making the connection impossible to completely eliminate in the past. It is possible to eliminate chemical formation defects caused by insufficient chemical formation.
