Description

  The present invention relates to a transport jig for transporting a battery component made of a magnetic material in a manufacturing process of a cylindrical battery or the like, and in particular, an improved flat battery transport jig which can efficiently transport a flat battery. It is about.

  In recent years, a disk-shaped and thin battery such as a coin-type battery or a button-type battery represented by a flat battery has been used as a drive power source for memory backup, communication equipment, watches, and the like. The demand for coin-type batteries that can maintain long-term reliability, such as a 10-year warranty that can withstand harsh environments as the main power source of these electronic devices, tends to increase. There is a demand for high-quality manufacturing with little variation. In particular, the amount of electrolyte to be injected is an important factor in determining the storage characteristics for ensuring the long-term storage stability of the battery, and there is a need for a management standard for strict accuracy of the amount of injection with little variation. . A coin-type battery is prepared by injecting a non-aqueous electrolyte into an upper case that houses an electrode body having a laminated structure of a negative electrode body, a positive electrode body, and a separator, and then covering the upper case with the lower case and covering the opening of the lower case. It is manufactured by caulking and sealing.

The flat battery is transported by a battery transport jig that holds a flat battery 70 that is caulked and sealed inside by a transport jig main body 71 shown in FIG. 8A. A plurality of magnets 72 are provided on the cross section of the conveying jig main body 71 on the inner surface of the cylindrical shape at the center of the conveying jig main body 71 shown in FIG. A method has been proposed in which the magnets 72 are arranged so as to be point-symmetric with respect to the center 74 of the hollow portion, and the flat battery 70 is held and transported by the magnets 72 (see, for example, Patent Document 1). .
Japanese Patent Laid-Open No. 10-64496

  However, with the prior art shown in the above-mentioned patent document, the battery battery components after sealing can only be transported alone, and it is difficult to simultaneously store and transport the battery components in one battery transport jig. The need for one transport jig for each battery component hinders productivity improvement, and in particular for coin-type batteries, the upper case is covered with the lower case and the opening of the lower case is covered. Before caulking and sealing, it takes a long time to inject the non-aqueous electrolyte into the upper case and impregnate the non-aqueous electrolyte into the electrode body made of a high-density active material. If left for a long time, the non-aqueous electrolyte is highly volatile, and the non-aqueous electrolyte evaporates due to vaporization of the non-aqueous electrolyte, resulting in variations in the amount of the non-aqueous electrolyte and changes in components. Therefore, in order to suppress evaporation of the non-aqueous electrolyte, it is necessary to immediately fit a lower case that covers the upper case.

  However, if the upper case and the lower case are fitted together before the non-aqueous electrolyte is sufficiently impregnated in the electrode body, the non-impregnated non-aqueous electrolyte scatters out of the upper case, resulting in the storage characteristics of the coin-type battery. Variations in the amount of non-aqueous electrolyte, which are factors, and dirt on the exterior of the coin-type battery occur. In the battery transfer jig jig of the prior art, the non-aqueous electrolyte evaporates when transporting the upper case filled with the non-aqueous electrolyte, and the electrode case is still impregnated by covering the upper case with the lower case The non-aqueous electrolyte which is not scattered will be scattered outside the upper case.
