業を短時間で行えるようにした。(Summary of the Invention) A first aspect of the present invention is a group of electrode plates for a lead-acid battery that forms a strap for connecting the ears of each electrode plate of the same polarity when configuring the electrode plates of a lead-acid battery. In the method for forming a strap, a precast molded product for a strap made of lead or lead alloy is formed with each lug insertion hole formed in the molded product fitted into the lug of each pole plate of the same polarity. When welding is performed using flux, the precast molded product for the strap and each ear inserted into each ear insertion hole are welded together to form a strap. It is sufficient to apply 7 lux to each edge of the electrode, and unlike conventional methods, excess flux may flow down the plate surface of the electrode plate and corrode the active material, causing a decrease in battery performance, or corrode the metal. I tried to eliminate such things. Also, even if the ears are small,
In the present invention, since it is only necessary to melt a small amount of lead, it is possible to achieve good welding without melting off the ears, and to perform the welding work in a short time.

A precast molded product for a strap for carrying out the forming method, which includes a base made of lead or a lead alloy, and an ear insert into which the ears of each plate of the same polarity of the plate group are inserted into the base. Since most of the strap is made up of the precast molded parts for the strap, only a small part of the strap is melted, which shortens the melting time of the part to be welded and the time for the molten part to solidify. This is designed to shorten the welding time.

A pole plate and a plurality of cathode plates are housed, and each pole plate of the same polarity is connected by a strap at each ear. One conventional method for forming straps involves placing multiple electrode plates housed in a common cell chamber with each ear facing downwards into a lake of molten lead in a mold. There is a cast-on method in which the material is immersed in water and then released from the mold after it has solidified to form a strap. This cast-on method is relatively easy to automate;
Recently, this method has been used in many cases of strap molding, but due to the high equipment cost, it is mainly suitable for mass production, and moreover, it is suitable for batteries with medium capacity. However, the cast-on method is not suitable for small electrode plates, thin electrode plates, large electrode plates, etc.

For lead-acid batteries that require a strap with a lead alloy composition (e.g., Pb-2%Sn alloy) that is completely different from the lead alloy (e.g., Pb-2%Sn alloy), the cast-on method is used because it is extremely difficult to set the welding conditions. The strap is not used and the strap is formed by burner welding. In the conventional method of forming a strap by such a burner welding method, as shown in FIG. Insert it and set the lower pad 4 for regulating the width of the strap. After that, while melting the additional lead 6 with the burner 5, each ear part 2 is also melted, and the molten additional lead 6 and each ear part 2 are melted.
A part of the amount is caused to flow into the space surrounded by the lower deposit 3 and the lower deposit 4. Next, add lead 6 which was left in this state and melted.
A strap was formed by solidifying a portion of each ear portion 2.

った。(Problem to be solved by the present invention) However, in recent years, there has been a trend toward maintenance-free lead-acid batteries, and electrode grids have been changed from conventional antimony-based lead alloys with good weldability to those that do not substantially contain antimony. Antimony-free lead alloys (e.g., Pb-Ca alloys, Pb-C
A-8N alloy, etc.), a thin and dense oxide film is formed on the surface of the molten antimony-free lead alloy, and the strap is not formed sufficiently and the strap falls off from the electrode plate ear. was there. Therefore, when using 7lux to improve weldability, when using the conventional barb welding method, a large amount of flux is required and the flux flows down the electrode plate ears, and this flowing flux causes the electrode plate lattice to be formed. There is also a problem that the active material is corroded, resulting in a decrease in battery performance. There was also the problem that the flux that flowed down corroded the deposit and the like.

There is no risk of depreciation or loss of funds. Further, even if the ear portion 22 is small, only a small amount of lead needs to be melted, so that good welding can be achieved without melting off the ear portion 22, and the welding action can be performed in a short time.

Since the strap is formed with holes 15, most of the strap is occupied by the strap precast molded product 11, and only a small portion is melted, so that the welding time for the welded parts can be shortened.

間の短縮を図ることができる利点がある。Further, according to the second aspect of the present invention, since most of the strap can be made of a precast molded product for straps, only a small portion is melted, and the melting time of the welded portion is shortened. There is an advantage that the solidification time can be shortened and the welding time can be shortened.
