【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、時計の製造方法に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a method of manufacturing a watch.
本発明は時計用ガラスの接着において、時計ケースとエ

としたものである。The present invention involves applying an epoxy resin adhesive to the watch case, installing the glass, and then filling it with a low-viscosity UV-curable adhesive and irradiating it with UV rays to achieve a high filling rate and waterproofing. This was an attempt to obtain a watch case with high quality.
従来の時計用ガラス接着方法としては、エポキシ樹脂接

ラス側面とケース間に生しる隙間に再度エポキシ樹脂を
充填し硬化を行っていた。Conventional watch glass bonding methods use epoxy resin adhesives, and after bonding the case and glass, the gap between the side of the glass and the case is filled with epoxy resin again and cured. .
〔発明が解決しようとする課題）
しかし、上記のような方法においては、接着剤の硬化処

低粘度のエポキシ樹脂がないため充填作業が困難である
欠点を有していた。[Problem to be solved by the invention] However, in the above method, the adhesive needs to be cured twice, and the adhesive needs to be adjusted twice due to the bot life of the epoxy resin. In addition,
It had the disadvantage that filling work was difficult because it did not contain a low-viscosity epoxy resin.

上記の様な構成によれば、接着剤の硬化処理工程が１回

の界面の強度も高めることができる。According to the above configuration, the adhesive curing process is performed only once, and the working time can be shortened. Furthermore, the low viscosity that cannot be obtained with epoxy resin adhesives improves fluidity, which increases the filling rate of the adhesive and improves the waterproofness of the bonded area. Furthermore, since the uncured ultraviolet curing resin comes into contact with the epoxy resin before it is completely cured, the strength of the interface between the two adhesive layers can also be increased.

In the figure, a stainless steel watch case 1 is electrolytically cleaned to completely remove the oxide film on the surface, and then a glass 3 is installed on which a bisphenol A-based epoxy resin adhesive 2 is applied. Further, a modified acrylic ultraviolet curable adhesive with a viscosity of 950 cps was applied to the gap created between the watch case 1 and the glass 3 using a dispenser, and was cured by irradiating ultraviolet rays with a high pressure mercury lamp.

It was found that adhesive strength as high as tA was maintained. Furthermore, in order to investigate the waterproofness, a pressurization test at IO atmospheric pressure was conducted, and the waterproofness was found to be good both at the initial stage and after the aforementioned durability test.
