2. Description of the Related Art In a wristwatch, for example, a button type battery is generally used as a driving power source. FIG.
1 is a cross-sectional view showing the configuration of the main part of a button-type battery as the driving power source, wherein 1 is a container that also serves as an anode, 2 is an opening of the container 1 fitted through an insulating packing 3. A lid (or container) which also serves as a cathode for liquid-tightly sealing the opening, 4 is an anode active material (silver oxide-manganese mixed system) filled in the container 1, 5 is a separator 6 in the container 1. It is a cathode active material (zinc particles) filled and filled via the. In the above structure, the insulating packing 3 electrically insulates the anode 1 and the cathode 2 and secures the liquid tightness of the button type battery. Further, the separator 6 functions to separate both active materials 4 and 5 and to proceed while controlling electric energy conversion between both active materials 4 and 5.

By the way, in the button type battery,
In order to ensure the required battery function sufficiently and efficiently, it is important in terms of quality that the filling amount of the anode active material 4 and the cathode active material 5 is appropriate, and that there is no void including the separator 6. To be done. That is, first of all, if the filling amount of the anode active material 4 and the filling amount of the cathode active material 5 are not controlled with high accuracy in accordance with the capacity and standard of the button-type battery, as a result, the anode and the cathode will end up. However, there is a problem in that the balance is lost, gas is generated after discharge, and the battery is easily destroyed. Secondly, if a void portion exists in the button-type battery (for example, the region of the separator 6), the void portion becomes an air trap and the discharge characteristic is deteriorated. In the active materials 4 and 5, the filling amount (for example, 30 mg ± 1 mg) of the zinc particles (cathode active material) 5 that easily influences the electromotive function and the like is emphasized.

However, the zinc particle weighing means is not only satisfactory in stability (reproducibility) and reliability, but also complicated in operation and is not satisfactory in terms of mass productivity. That is, the particle size (particle size) of the zinc particles (zinc particles) used as the active material of the button-type battery generally differs depending on the manufacturing method, manufacturing lot, etc. Even if there is, the filling amount is different. In other words,
It is often recognized that even if the apparent volumetric weighing of zinc particles by the constant weighing plate 9 is the same, a certain allowable range cannot be secured due to a difference in mass. Therefore, when the weighing plate 9 provided with the measuring through holes 9a is used, the measuring through holes are used each time corresponding to the manufacturing lot of zinc particles.
It is necessary to measure the filling amount in 9a and change / adjust to the weighing plate 9 provided with an appropriate through hole 9a for weighing. But,
In the sliding / advancing / retreating construction of the weighing plate 9, since it is necessary to weigh zinc particles with high precision, high precision is required mechanically. Therefore, proper selection / change / adjustment of the weighing plate 9 is required. The work is inevitably complicated. In other words, the zinc particles can be accurately weighed by properly selecting, changing, and adjusting the weighing plate 9, but on the other hand, the adjustment work is complicated and the mass productivity cannot be sufficiently improved. There is.

Moreover, it is possible to perform measurement with good reproducibility. In other words, when changing the lot of zinc particles to be used, other than selecting the required through-hole for measurement by confirming whether the amount of zinc particles weighed / filled is within the specified range or not by so-called sampling. In addition, the amount of zinc particles as the battery active material can be accurately and easily measured without requiring complicated operations and mechanical adjustments and without requiring a skilled worker. . And, it can be said that such switching of the through holes for measurement and shortening of adjustment time, and elimination of skill required greatly contribute to the improvement of productivity of button type batteries.
