があった。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the welding method according to the above method, the film bag 2 is stretched by heating the film bag 2, and the side surface 5 including the bow and stern of the molding cap 1 is pressed at the same time. There is a problem that slack occurs, and after welding, wrinkles 10 shown in FIG. 6 remain on the welded surface, and airtight leakage occurs from this portion, resulting in a very poor manufacturing yield.

る。Means for Solving the Problems The present invention has been made to eliminate the above-mentioned drawbacks,
While sandwiching the film with a hot plate having the same inner surface shape as the side surface excluding the left and right ends of the molding cap to weld it, and then sandwiching it further with the hot plates that contact the left and right ends of the molding cap to form a concave shape. It is characterized by welding.

好な溶着を可能にするものである。Action Due to the above features of the present invention, since the film is not welded at the left and right ends of the molding cap in the initial stage of welding, the stretch and slack of the film escape to the left and right ends of the molding cap, and wrinkles occur on the welding surface. It enables uniform welding without any problems, and at the next stage of welding the left and right ends of the molding cap,
Since the number of welded portions is small, the film is not stretched or loosened, which enables good welding.

成しつつ２００℃で１秒間加熱して溶着を行う。First, the welding of the film bag 2 and the molding cap 1 in the sealed lead acid battery using the film bag 2 made of a thermoplastic synthetic resin such as polypropylene and the molding cap 1 shown in FIG. 1 is shown in FIG. 3, side surface 5 of the molding cap 1 as shown in Fig. 3 (1) that can be welded leaving the stern 4
With the hot plate 6 having the same shape as the above, the film bag 2 is arranged between the molding cap 1 and both hot plates 6, and the molding cap 1 is sandwiched with the hot plate 6 as shown in FIG. Heat for 6 seconds to weld. Next, as shown in FIG. 4, the R portion 8 whose inside of the tooth end is R-shaped by the clog-shaped hot plate 7 is pressed against the bow 3 and the stern 4 of the molding cap 1 as shown in FIG. 4 (2). While forming the concave surface shape, heating is performed at 200 ° C. for 1 second to perform welding.

がある。EFFECTS OF THE INVENTION As described above, according to the present invention, the welding of the molding cap and the film bag is divided into a plurality of stages, and the side of the molding cap excluding the bow and stern is first welded, and the bow and stern are later welded. Since this method is adopted, wrinkles do not occur on the welding surface, and there is an effect that there is no airtight leakage in the battery at the welding surface between the molding cap and the film bag, which is 60% in the manufacturing process.
