電池の組立工程の中にあり、注液速度が遅いと、
工程全体に与える影響が大きい。このようなこと
から従来より注液方法について検討が行なわれ、
その代表方法として以下のようなものがあつた。Conventional Structure and Problems Injecting electrolyte into a battery is an important step in terms of battery reliability, as it has a great effect on battery performance depending on the accuracy and method of injection. In addition, liquid injection is usually part of the battery assembly process, and if the liquid injection speed is slow,
It has a large impact on the entire process. For this reason, liquid injection methods have been studied for some time.
The following are representative methods:
(1) 電解液を何回かに分割して注液する。(1) Inject the electrolyte in several doses.
(2) 電池に振動を与えながら注液する。(2) Inject liquid while applying vibration to the battery.
(3) 電解液を加温して注液する。(3) Warm and inject the electrolyte.

よつては、適用出来ないものもある。これら(1)〜
(3)の方法は、前述したとおり電池の信頼性、組立
工程上において問題があつた。 Method (1) above is currently widely used, but it requires several injection machines, and if the injection speed is slow for batteries, the number of divisions must be increased, which is proportional to the number of times the injection is performed. Therefore, it is necessary to add more liquid injection machines.
Equipment costs will be high. Method (2) is easy to implement in terms of equipment, but the electrolyte tends to scatter due to vibration, which tends to cause leakage resistance problems. Method (3) involves lowering the viscosity and surface tension of the electrolyte to increase the injection speed, but this method may not be applicable depending on the type of battery. These (1)～
As mentioned above, method (3) had problems in battery reliability and assembly process.

整することが出来る。Structure of the Invention In order to achieve the above object, the present invention includes a drive unit that generates centrifugal force, and a bar-shaped rotating unit that transmits the centrifugal force to a battery support and a funnel-shaped liquid injection tube disposed on the top of the battery support. Equipped with a liquid injection device consisting of a
A centrifugal force is applied to the electrolyte in the funnel-shaped liquid injection tube whose liquid injection port is closed by the upper part of the electrode group in the battery can or resin case supported by the battery support, and the acceleration G applied to the electrolyte is Therefore, the feature is that the liquid is injected into the electrode group inserted into the battery can or resin case. According to this method, the
There is no need to divide the injection as in (1), and there is no scattering of the electrolyte as in (2), so injection can be completed instantly. Furthermore, there is no need to heat the electrolytic solution to change physical properties such as viscosity as in (3). The acceleration applied to the electrolyte can be easily changed by changing the number of revolutions at which the battery is rotated and the distance from the rotating shaft to the injection part, so it can be adjusted according to the structure of the battery and the physical properties of the electrolyte.

径を100mm、回転速度500rpmとした。 Figure 1 shows a non-sintered positive electrode plate 1 whose main active material is nickel hydroxide, and a paste-type negative electrode plate 2 whose main active material is cadmium oxide, with a separator 3 made of nylon nonwoven fabric interposed between the two electrodes. , after winding it in a spiral shape to form the electrode group 4, this is placed in the battery case 5.
This is a nickel-cadmium battery 12 inserted into the battery. FIG. 2 is a side view of the centrifugal liquid injection device used in the present invention. The battery 12 with the electrode group inserted is mounted on the battery support 13 shown in the figure, and the funnel-shaped liquid injection tube 6 placed above the battery 12 is inserted so that the liquid injection port 6a is above the electrode group as shown in FIG. After adhering to the liquid injection tube support 11 in a closed state, the required amount of electrolyte is injected into the liquid injection tube. When the motor 8 is then rotated, the rotating shaft 9 of the motor 8 and the bar-shaped rotating portion 7 connected thereto are rotated. When rotation begins, centrifugal force moves the battery support 13 around the support holding shaft 10 to a position parallel to the bar-shaped rotating part 7, and the electrolyte in the liquid injection tube 6 is filled with the battery support 13. The liquid is injected using the acceleration G based on the centrifugal force that acts. A comparison was made between the conventional liquid injection method and the liquid injection method according to the present invention using the above-mentioned nickel-cadmium battery. The electrolytic solution used has a specific gravity of 1.30 KOH, and 2 c.c. of the electrolyte is injected into the electrode group.The method of injecting the electrolyte is the divided injection method of the conventional example (1), and the centrifugal method of the present invention. A comparison was made with a method of injecting liquid using acceleration due to force. The apparatus shown in FIG. 2 was used in the method of the present invention. The conditions of the apparatus were that the radius of the bar-shaped rotating part 7 was 100 mm and the rotation speed was 500 rpm.

て注液完了後の封口作業も確実に実施できる。 For comparison, in order to eliminate variations in the injection rate due to the degree of dryness of the separator, the electrode groups of both batteries were preliminarily dried in vacuum at a temperature of 60° C. for 1 hour before injection. As a result, the method of the present invention can inject a predetermined amount of electrolyte in 3 seconds, whereas conventional example (1), which divides the injection method, takes 120 to 180 seconds to complete injection. I can do it. In addition, when pouring the liquid in parts, the electrolyte forms beads on the separator due to surface tension.
The electrolyte tends to come into contact with the sealing part of the battery can, but since the injection was completed instantaneously using centrifugal force, there was almost no contact with the sealing part of the battery can. Therefore, the sealing operation after the completion of liquid injection can be carried out reliably.

As a result, mass productivity can be improved.
