産業上の利用分野
本発明は、密閉形鉛蓄電池の製造法の改良に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improved method for manufacturing sealed lead-acid batteries.
従来の技術

、排気口３より電解液を注入していた。Conventionally, as shown in FIG. 3, this type of sealed lead-acid battery has a frame body 1 surrounding a group of electrode plates consisting of a positive electrode plate, a negative electrode plate, and a separator, and a heat-fusible resin layer on the inner surface. The electrolytic solution was injected through the exhaust port 3 after the electrode plate group was sealed by thermally welding the metal side plates 2 and the metal side plate 2 provided with the electrode.
発明が解決しようとする課題
このような従来の構成では、電池内部にほとんどデッド

３より溢液し、生産性が悪いという問題があった。Problems to be Solved by the Invention In such a conventional configuration, in the case of a battery with almost no dead space inside the battery, the electrolyte injected from the nozzle V passes through the separator to the positive electrode plate and the negative electrode plate. Because the electrolyte diffuses and replaces the air inside the battery at the same time, it takes a long time to inject the liquid.If the injection speed is increased, the electrolyte that is not absorbed by the electrode plate group and is released will flow into the exhaust port 3 along with the air inside the battery. There was a problem of more liquid overflowing and poor productivity.
このため、電池内部に遊離した電解液をためておくデッ
ドスペースを大きくとらなければならず、電池の体積効
率が低下するという問題があった。Therefore, it is necessary to provide a large dead space for storing the liberated electrolyte inside the battery, resulting in a problem that the volumetric efficiency of the battery decreases.
本発明はこのような課題を解決するもので、注液速度を

ドスペースを排除し体積効率を向上させることを目的と
したものである。The present invention is intended to solve these problems, and in addition to improving productivity by increasing the injection speed, the present invention aims to improve volumetric efficiency by eliminating dead space inside the battery.

。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a structure made of synthetic resin that contains an electrolytic solution in both or one of the positive electrode plate and the negative electrode plate and the separator, and then houses the electrode plate group. The frame body and the metal side plates are heat-welded to each other and sealed.

実施例
以下本発明の実施例について第１図、第２図を参照して
説明する。EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2.
第１図は、枠体１と、正極板あるいは負極板のどちらか

を相互に熱溶着して密閉するものである。In Figure 1, a frame 1 and a metal side plate 2, which has either a positive electrode plate or a negative electrode plate fixed to it and a heat-fusible resin layer provided on the inner surface, are heat-welded to each other. . After heat welding, insert the separator 4 with the electrode plate surface as the upper surface, inject a predetermined amount of electrolyte from the separator surface, and then place the other negative or positive electrode plate forming the electrode plate group together with the electrode plate and separator, The other metal side plate 2 and the frame 1 are thermally welded to each other and sealed.

していた。FIG. 2 shows the relationship between the ratio of dead space to the battery internal volume and the time required for liquid injection. The amount of electrolyte is constant at 78 cm, which is the internal space volume of the positive electrode plate, negative electrode plate, and separator under group pressure. In the conventional method, if the dead space is made smaller, the liquid released during injection will overflow from the exhaust port 3, which increases the time required for injection. It took more than a minute.

れにより電池の体積効率は約１０チ向上した。According to the present invention, the electrolyte is injected into the inside of the battery that houses the electrode plate group in an open state, and then the resin frame 1 and the metal side plate 2 are thermally welded to each other and sealed. Diffusion of the electrolyte into the plate group and replacement of the electrolyte with air inside the electrode plate group occur very quickly. Therefore, it becomes possible to increase the liquid injection rate, and at the same time, there is no need to provide a dead space for retaining the liberated electrolyte inside the battery. In the case of this example, the time required for injection is 3 to 6 seconds, which is 10 to 20 times faster than the conventional method.
In addition to being able to improve productivity, the dead space inside the battery, which conventionally required more than 10%, has been eliminated, and the volumetric efficiency of the battery has improved by approximately 10 cm.
