Abstract

PURPOSE:To prevent the resin sealing between a partition wall and an intercell- connecting part from becoming incomplete by manufacturing a strap and the intercell-connecting part simultaneously by casting molten lead in a mold for a storage battery. CONSTITUTION:The lags of anode plates 1 and cathode plates 2 are immersed in molten lead 8, and extracted after the molten lead is solidified. As a result, a movable mold 7 opens, and a strap, an intercell-connecting part and an electrode pole are formed, thereby completing an electrode group. Here, since the four sides of the intercell-connecting part are surrounded by a fixed mold 5 and a movable mold 7, the intercell-connecting part can be formed into a given shape, and any defective sealing of this part can be prevented. Next, after the electrode group is completely inserted into a container 4, the intercell-connecting part is subjected to resin formation, and a lid is installed over the electrode group so as to complete a storage battery.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a storage battery in which a strap and an intercell connection part are simultaneously cast and integrated with a plate lug.

The above-mentioned method of manufacturing an electric storage battery has been proposed in the past, but due to the bulge of molten lead at the connection between the cells, it has not been possible to achieve a fixed result.

For this reason, there have been disadvantages in that the twilled portion of the capacitor comes into contact with the cell partition wall, or that the resin sealing between the capillary partition wall and the inter-cell connection portion is incomplete.

The present invention has been made in view of the above points.

In a method for manufacturing a storage battery having a value number of cells.

The anode plate and the cathode □ plate are laminated through seven pallets, and the lug of one of the anode plate or cathode plate of the - cell is electrically connected to the cathode plate of the adjacent cell. and the ears of the other plate.

The part corresponding to the connecting part between - and # is placed in a mold surrounded on all four sides over a length of at least 1 cm, and
This method is characterized by simultaneously manufacturing the striped wrap and the inter-cell connections by pouring molten lead into the test lid.

The present invention will be explained below with reference to drawings showing one embodiment thereof. In other words, in Figure #11, the anode plate 1 and the cathode plate 2 are stacked with the separator #5 in between, and this is inserted into the battery case 4 at a point t, turned upside down, and connected to the strap and the inter-cell connection. A fixed J15 with a pole and pole engraved on it, and a movable J15 with a pressed width of 2 sIl so as to be in contact with the part corresponding to the connection between the cells of the cast A15. FIG. 2 is a perspective view at a time when molten lead 8 is poured into a cast iron and the lugs of the anode plate 1 and cathode plate 2 described above are about to be immersed in the molten lead 8.

In the turning section, fh tools for the electrode plate and battery case, moving devices, moving devices for the mold, a device for casting into the armor layer, etc. are omitted so that the present invention can be more clearly understood.

When the lugs of the anode plate 1 and the cathode plate 2 are immersed in molten lead 8, and pulled out after the molten lead 8 has solidified, it becomes movable! 7 is opened and the straps, intercell connections and pole posts are carved, thus completing the pole group.

In this case, the four circumferences of the cell section are the fixed armor layer 5 and the movable armor layer 5 and the movable layer 1 [7, so l! Since it is sealed, it can be formed into a fixed shape, thereby preventing incomplete sealing of the menstrual region.

Thereafter, the electrode group is completely inserted into the battery case 4, the connecting portion between the cell rods 1 and 1 is molded with resin, and a lid is provided, thereby completing the storage battery.

Although one embodiment of the present invention has been described above in detail, the present invention is not limited thereto, and various embodiments can be considered without departing from the gist thereof. For example, in the above embodiment, the strap and the cell 1/#M section were manufactured after inserting the positive and negative electrode plates and the seventh separator halfway into the battery case. The lugs of these plates were placed in a single layer and molten lead was poured into them, and the strap and inter-cell connections were manufactured and detailed. may be inserted.

Value 9: The present invention has extremely high value.
