食させるなどの問題があった。Conventional technology Conventionally, an insulating material has been interposed between the positive and negative terminals of a battery that are exposed on the same surface to prevent short circuits due to contact with external metal parts or liquid junctions due to condensation. Efforts were made to prevent this. Especially lithium batteries,
When a high-output battery such as an alkaline battery is short-circuited, a large current flows, causing the battery itself to generate heat and deform the battery seal, or cause internal electrolyte to leak and damage the equipment used, or cause moisture etc. When there is a liquid junction between the two electrode terminals, electrolysis of water occurs in batteries such as lithium batteries that exhibit a potential of 3V, causing problems such as corrosion of the terminal metal. .

されつつある。Alternatively, two-component adhesive compositions are the main type, but they take time to harden, and solvent-soluble adhesive compositions require a process to splash the solvent on the production line, making it difficult to manufacture batteries. This resulted in higher costs. On the other hand, UV-curable adhesive compositions are solvent-free and have the effect of instantaneous adhesive curing upon irradiation with UV rays, so they are becoming more widely used.

う問題があった。Problems to be Solved by the Invention When an ultraviolet curable resin is used between the exposed parts of the positive and negative terminals of a battery, the ultraviolet curable resin instantly becomes useful by absorbing ultraviolet rays. The higher the transparency level of the color before curing, the more easily it absorbs ultraviolet rays, and therefore the faster it is cured. However, recent consumer needs favor products with rich designs in terms of appearance, and in terms of quality control, by adding a slight color to the resin, the exposed parts of the battery's terminals can be completely UV-cured. It is effective to apply some kind of coloring so that it can be determined that it is covered with resin. In addition, the colored UV-curable resin is cured by irradiating it with UV rays, but on the production line, the UV irradiation part is completely hidden from view so that the irradiated UV rays cannot be seen directly. It is shielded, so in the unlikely event that the output of the mercury lamp, which is the source of ultraviolet light, decreases,
Alternatively, if the life of the adhesive has expired, there is a problem in that the ultraviolet curable adhesive is produced in a state that has not completely hardened.

題点を解決するものである。Means for Solving the Problems The present invention provides the following features: - The use of a coloring agent having a chromophore whose color tone changes sharply due to ultraviolet rays as the coloring agent for the ultraviolet curable resin, and the use of an ultraviolet curable resin in the culm.

By irradiating ultraviolet rays, radical groups are generated within the molecule to radically polymerize and harden the polymer. For example, unsaturated polyester resin,

If the output of the mercury lamp, which is the light source of the battery, decreases, by setting up a process to monitor the change in color tone visually or using a colorimeter, etc., it is possible to prevent the production of uncured resin products. This eliminates the possibility of uncured resin adhering to the surface or contaminating the production line with uncured resin, making it possible to provide a battery manufacturing method that is extremely effective in terms of quality control and production control.
