産業上の利用分野
本発明は密閉形鉛蓄電池の製造法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for manufacturing a sealed lead-acid battery.
従来の技術
密閉形鉛蓄電池の電槽に要求される特性の一つ
として、酸素および水蒸気の透過度が小さいこと

いる。BACKGROUND ART One of the characteristics required of a case for a sealed lead-acid battery is low oxygen and water vapor permeability. However, in order to satisfy these characteristics with a single container material, the thickness of the container becomes large, which is disadvantageous in terms of volumetric efficiency. Therefore, various attempts have been made to create battery cases using multilayer laminate films that have low oxygen and water vapor permeability and are thin.

トバーをあてるとフイルムのみが薄いために早く
溶けすぎてしまい、良好な溶着ができない。Problems to be Solved by the Invention Among these, in the case where the above-mentioned film is attached to the terminal sealing part (hereinafter referred to as "block") made by injection molding of plastic in the external terminal part, If the material is polyolefin resin, it is difficult to bond with adhesive, and even when heat welding, if you place a plastic film on top of the block and apply a heat bar over it, only the film will be thin. It melts too quickly, making it impossible to achieve good welding.
本発明はこれらの問題点を解決するものであ

とを特徴とするものである。Means for Solving the Problems The present invention has been made to achieve the above object, and consists of placing a light-transmitting plastic film on a light-absorbing block and pressing this with a glass plate. However, the block is further characterized by applying light from above to heat and melt the block before the plastic film, thereby thermally welding it to the plastic film.

溶着部が得られるものである。Function The present invention has the above-mentioned characteristics, so that instead of only the plastic film being melted and welded to the block, the plastic film is also melted by the heat of the previously melted block, and both are welded together in a molten state. As a result, a highly reliable weld can be obtained.

の上に光源５を配置する。Example An example of the present invention will be described. As shown in FIG. 1, an external terminal 2 is injection molded from a polypropylene resin colored with a black pigment to obtain a block 1. A transparent plastic film 3, which becomes a part of the battery case, is brought into contact with this, and a transparent glass plate 4 is pressed against it from above, and a light source 5 is placed on top of it while applying pressure.

られた。 When light is irradiated from the light source 5 in this state, the light passes through the transparent glass plate 4 and the plastic film 3 and is absorbed only by the black block 1. Therefore, only the block 1 begins to melt, and the plastic film 3 that is in contact with the block 1 melts due to the heat. After the two melts were mixed together under pressure, they were cooled and solidified to form the welded part 7, yielding the battery shown in FIG. 2.

品と比べて溶着部の信頼性が飛躍的に向上した。 In the conventional method of thermally welding the block 1 and the plastic film 3 using the heat bar 6 shown in Fig. 3, the order of melting the block and film is reversed, and the block is melted first and then the film is melted. However, the product of the present invention in which both are welded has dramatically improved reliability of the welded part compared to conventional products.
発明の効果
上述したように、本発明によれば、薄いプラス

不良や、溶着強度の低下が防止されて電池の密封
性が向上するという効果がある。Effects of the Invention As described above, according to the present invention, since the thick block part is melted before the thin plastic film part to weld the film and the block, it is possible to reduce the melting degree of the film part. This has the effect of preventing poor welding due to excessive melting of the film and a decrease in welding strength, thereby improving the sealing performance of the battery.
