[Prior Art] Conventionally, there is a cast-on method as one of the methods for forming a strap for a lead-acid battery plate group. A conventional example of strap formation using this cast-on method will be briefly explained with reference to FIG. A mold 3 in which a so-called strap recess 4 is dug is placed, molten lead 9 is poured into the strap recess 4, and the plate lug 2 is immersed in the molten lead to form the straps and poles of the plate group. At the same time, the edges of the electrode plates are connected by straps. In addition, in the figure, 13 is a pouring port, and pouring port 1
3 has a pouring groove 14 dug therein for receiving the molten lead 9 flowing out from the melting pot 7 and injecting it into the strap recess 4. Further, 6 is a weir, which is provided on the spout 13 side of the strap recess 4.
Its role is to allow excess molten lead to overflow and to maintain a constant thickness of the strap.

[Problems to be Solved by the Invention] However, when the conventional mold 3 as described above is used to form the strap of the electrode plate group by the cast-on method, there are the following drawbacks.

(a) In order to keep the strap thickness constant, the mold 3 is provided with an overflow dam 6 on the spout side of the strap recess 4. However, if the overflowing molten lead 9 does not drain properly, As shown in the figure, the lead solidified at the weir connects with the strap, resulting in the formation of so-called external burrs 17. Also, molten lead 9 from pouring port 13
As shown in FIG. 7, the injected molten lead hits the wall of the strap recess 4 opposite to the pouring spout 13, and the lead solidified on the wall is poured into the strap recess 4 of the mold 3. This has the disadvantage that so-called internal burrs 18 are more likely to occur. As mentioned above, if external or internal burrs adhere to the strap, it may cause problems when using the storage battery.
This may cause an electrical short circuit. However, because the shape, volume, and attachment location of external and internal burrs are uncertain, it is extremely difficult to develop equipment that completely removes these burrs.Currently, the only method available is manual labor, which is the key to labor savings. It's summery.

(b) Since the molten lead 9 must be poured into the strap recess 4 of the mold 3 at a distance from the pouring spout 13, the molten lead 9 may be contaminated due to adhesion of lead oxide in the pouring groove 14 of the pouring spout 13. If the flow rate decreases, a portion of the molten lead 9 that should be poured into the strap recess 4 will scatter, and a certain amount of molten lead 9 will not be injected into the strap recess 4, resulting in a thin strap. There are drawbacks that are formed. If the thickness of the strap is thinner than the required thickness, the connection between the pole plate tab and the strap will be insufficient, which may cause problems during use of the battery.
The electrode plate ears may come off from the strap, causing a defect.

(c) If the plate lug is the middle lug, it is necessary to move the mold 3 inward in order to match the strap recess 4 of the mold 3 with the plate lug 2. However, due to the position of the pouring port 13, It hit Group 1 and could not be moved inward, making it extremely difficult to inject molten lead 9 into the strap recess 4 of the mold 3, making it impossible to form a strap using the cast-on method.

In addition, the electrode plate ears are the middle ear, that is, the middle ear electrode plates, in order to lower the current collecting resistance of the grid, as shown in Fig. 4 2.
Refers to a plate with a structure in which the plate ears are aligned to the center of the grid. On the other hand, a so-called end-edge electrode plate is one in which a current collecting resistor is not taken into consideration, and electrode plate lugs are provided in the vicinity of the side edges of the grid as shown in FIG. 5.

FIG. 1 shows an embodiment of the method for manufacturing a strap for a storage battery plate group according to the present invention, in which reference numeral 1 denotes a plate group, which is inverted so that the plate ears 2 are at the bottom. Further, the electrode plate group 1 is clamped by a clamp mechanism (not shown in the figure) that can be raised and lowered. Reference numeral 3 denotes a mold, in which a strap recess 4 and a runner 5 are dug, as shown in FIG. It is arranged below the board group 1. Further, the runner 5 of the mold 3 is dug in connection with the strap recess 4, and its width L1 is made sufficiently smaller than the width L of the strap recess 4. Further, the end of the runner 5 is located outside the side edge of the electrode plate group 1. Reference numeral 6 denotes a weir attached to the end of the runner 5, which functions to overflow excess molten lead and keep the thickness of the strap constant. However, if the amount of molten lead injected is stable and always constant,
There is no need to inject extra molten lead to cause overflow. A melting pot 7 is equipped with a heater 8 inside and is filled with molten lead 9. Normally, the molten lead 9 is discharged by lowering a valve seat 10 on the bottom of the melting pot 7 and a needle valve 12 that moves up and down. Prevents leakage. Further, a pouring port 13 is installed below the melting pot 7, and a hole 11 in the valve seat 10 and a pouring groove 14 are provided.
are made to match. The tip of the pouring spout 13 is spaced at an appropriate distance A so that the plate group 1 does not hit even if the plate group 1 descends, and the entire amount of molten lead 9 passing through the pouring spout 13 is placed in the strap recess of the mold 3. It is better to install it inside the weir 6 (B≧0) so that it is injected into the weir 4 and the runner 5.

Next, strap formation according to an embodiment of the present invention will be explained. First, when the needle valve 12 is raised using a cylinder or the like (not shown in the figure), the molten lead 9 in the molten metal pot 7 reaches the valve seat 1.
The amount of molten lead 9 that flows out forcefully from the hole 11 of 0, passes through the pouring groove 14 of the pouring port 13, and is injected into the runner 5 and the strap recess 4 in the mold 3 is set in advance using a timer or the like. Then, when the set time is over, the needle valve 12 is lowered and brought into close contact with the valve seat 10 to stop the molten lead 9 from flowing out. Immediately after the injection of molten lead 9 is completed, the plate group 1 is lowered and the plate lug 2 is immersed in the molten lead in the strap recess 4. After cooling for a certain period of time, when the plate group 1 is raised, a strap 15 is formed on the plate lug 2, and a runner lead 16 is formed integrally with the strap 15, as shown in FIG.
In the next step, the runner lead 16 is cut from the strap 15 to complete the process.

In this way, in the embodiment of the present invention, the mold 3 provided with the runner 5 is used, and the molten lead 9 is once dropped into the runner 5 and then injected into the strap recess 4. The force with which the molten lead 9 is injected is necessarily small, so that internal burrs do not form on the strap 15. Furthermore, since the runner 5 is provided, the strap 15 is only formed with the runner lead 16, and external burrs do not occur as in the conventional case. Note that the runner lead 16 corresponds to the conventional external burr, but since the shape and attachment location of the runner lead 16 are constant, cutting the runner lead 16 is mechanically easy. can be done. In addition, since the runner lead 16 integrally formed on the strap 15 is very small,
Even when cut, the amount of lead residue is small, and even when the lead residue is melted and used again, the thermal energy required for melting can be reduced, resulting in extremely high productivity. Furthermore, since the tip of the pouring spout 13 can be provided above the runner 5, the entire amount of molten lead 9 can be injected into the runner 5 and the strap recess 4, so that a thin strap can be formed. Nothing happens. Furthermore, the strap 15 obtained in the embodiment of the present invention includes runner lead 16
Since the straps are integrally molded, there is an advantage that the thickness of the strap 15 can be mechanically inspected at the runner lead 16.

FIG. 4 shows another embodiment of the method for manufacturing a strap for a storage battery plate group according to the present invention. In the figure, the same reference numerals as in FIG. 2' is a plate lug. That is, this embodiment shows an example of a method for forming a strap on the plate lugs of a plate group using middle ear plates, and the mold 3
The strap recess 4 is moved inward compared to the embodiment shown in FIG. 1 in order to match the plate lug 2' of the middle ear plate group 1'. However, since the pouring spout 13 corresponds to the middle ear electrode plate group 1', it is necessary to leave an appropriate distance A therebetween, as in the case of the outer ear electrode group. Further, in order to inject the entire amount of molten lead 9 passing through the pouring spout 13, the tip of the pouring spout 13 needs to be located inside the weir 6 (B≧0). Therefore, the runner 5 is made longer than the embodiment shown in FIG. 1 by that amount. The steps from injection of molten lead to strap formation are the same as in the embodiment shown in FIG. As described above, according to this embodiment, the strap can be easily formed even in the middle ear electrode plate group by the cast-on method.
