The purpose is to stabilize quality.

の極板２を挿入挾持して巻回するものである。Conventionally, in batteries using spiral electrodes, such as sealed nickel-cadmium storage batteries, a pair of positive and negative thin plates is generally connected via a separator using a winding device having a winding axis as shown in Figure 1. The wound electrode plate group was removed from the winding shaft and stored in the battery container. The one shown in Figure 1A has a vertical slit S corresponding to the thickness of the pole plate or separator wound around one side of the shaft, and B
The one shown in 2 shows a winding shaft in which a slit is formed by subtracting the thickness of the electrode plate, etc. into two parts and aligning the blades attached to the left and right rotating shafts. The electrode plate 2 is inserted and held and wound.

を得なかった。The connection between the electrode plate group wound in the above method and the positive and negative electrode terminals of the battery is made by pressure contact between one electrode plate, which will be on the outer periphery after winding, and the inner periphery of the metal battery container, and the other. A lead piece is provided on the electrode plate, and this is attached to a metal sealing plate by a method such as welding. In this case, as shown in the cross-sectional view of FIG. 3B, the electrode plate group that is wound and stored so as to fill the battery container is located between the center Q1 (solid line) of the battery container and the electrode plate group. There is always some deviation from the winding axis Q2 (dotted line). In the winding method shown in FIG. 1, the winding shaft is provided on the winding device side, so in production, the winding shaft must be able to be used continuously many times and must also have good operability. For this purpose, the diameter of the winding shaft must be at least three sides, preferably four or more sides. However, when it comes to small batteries with a small diameter, for example, an outer diameter of 12 mm or less, the winding shaft must be made as thin as possible in order to not reduce the capacity per volume of the battery. Therefore, in the conventional winding method described in -1-, the battery capacity had to be reduced or the ease of assembly had to be sacrificed.

えられている。As shown in Fig. 2, a method of winding a spiral electrode is to provide a winding core 1C that also serves as the lead and lead of one electrode plate on the battery sealing lid y itself, and wind it using this. is considered.

るが、各極板。In this case, as shown in A and B, one end of the lead/winding core 1C is cut into the center of the metal Kawaguchi plate 1a to hold one of the electrode plates 2 or the separator. It was integrated by L-welding 1d. The electrode plate 2 held between the sulins 1 to S of the winding core 1C is the sealing plate 1a.
Or the insulating gasket part 1b molded on its outer periphery
is held in a chuck of a winding device and rotated, thereby being wound as shown in C. Subsequently, a separator and other electrode plates are inserted and wound to form an electrode plate group. This method can be applied to batteries with a low height, but the winding core 1C
is provided at the center of the sealing lid 1, so when the electrode group is housed in a battery container and sealed, the center of the container and the center of the electrode group coincide as shown in Q, as shown in FIG. 3A, but the battery The inner periphery of the container 5 and the negative electrode plate 2. Separator 3. A space is formed between the positive electrode plate 4 and the outer periphery of the electrode plate group made up of the positive electrode plate 4 over half the circumference or more, which impairs the volume utilization rate of the container 5. On the other hand, the electrode wound using the conventional method is as shown in FIG. 3B, and when the two are compared, it can be seen that the electrode plate length is shorter in the case of FIG. 3A. As an improvement to the ones in Figures 2 and 3A, based on Figure 3B, calculate the position where the axis of the □ winding core of the wound electrode plate group deviates from the center Q of the battery container, and make a prediction. It is also possible to fix the damply wound core 1C eccentrically, but each electrode plate.

後で短絡する原因になりやすい。The one shown in FIG. 4 is another improvement plan, in which a nail-shaped winding core 11 is provided with a large diameter head 11a on one part of a thin round bar, and the core material of one of the electrode plates 2, For example, the tip of a metal porous plate, net, etc. is fixed by spot welding 12, etc., and the head 1 of the winding core is
1a is fixed to a chuck of a winding device and wound. After winding, the electrode plate group is passed through a guide corresponding to the inner diameter of the battery container, and the head 17a of the winding core is welded to a metal sealing plate. This is a method of fixation. With this method, there is no problem even if the winding axis of the electrode plate group and the center of the battery container are slightly misaligned, and there is an advantage that even a relatively thin winding core can be used. However, in this method, when winding, only the head 11a is supported on a cantilever, so when applied to a small battery with a small diameter, the head becomes small, so a strong supporting force cannot be obtained, and vibration occurs. This tends to cause problems or loosening during winding. In order to improve this, it is conceivable to provide an extension shaft part 110C on the nail-shaped winding core 110 to support the opposite side, as shown in Figure C, and cut it off after 9 windings, but it is also small in diameter and tall. When the electrode plate group is low, it is not easy to cut it during the process, and even if it is cut, the small pieces may adhere to the electrode group or damage the group.
This may easily cause a short circuit later.
さらに同図に示す１１０ｂのようなネックを入れてもあ
まり改善できなかった。Furthermore, even if a neck like 110b shown in the same figure was added, little improvement could be made.

の原因になるなどの問題があった。In addition, since the tip of the core material of the electrode plate 2 is fixed to the surface of the winding core by welding or the like as shown in D, the tip corner 2a may bulge or burr during assembly, causing the separator to get stuck in the separator and cause an internal short circuit. There were problems such as:

なく缶内スペースを有効に活用することができる。The length r of the winding core shown in Figure 6B can be set to the length required after battery assembly from the beginning, and there is no risk of short circuits due to metal powder or deformation of the electrode plate group caused by cutting in the later process. None. Furthermore, when winding the electrode plate group, the winding core 2o is supported at both ends as previously explained in FIG. 8, so it does not become eccentric. Since the portions 3CjC are folded into the slits S of the winding core, there is no slippage during winding, so that a uniform electrode plate group configuration can always be achieved with an appropriate degree of tightness. Furthermore, since the winding core 2o is initially separated from the sealing plate 26, the center of the electrode plate group can be shifted from the winding core of the group, as shown in cross section in FIG. 3B, and the center of the battery. Therefore, the space inside the can can be effectively utilized without creating a space.
