Problems solved by technology

[0006] However, as disclosed in the above-mentioned JP Patent No. 2651036 (Patent Document 1), the method of adding a probe that emits light as a function of the curing degree of the curable material to the ultraviolet curable resin is generally difficult. Difficult to apply to general-purpose UV curing methods
That is, adding a special material like the above-mentioned probe is not cost-effective, and in addition, from a quality point of view, adding that kind of probe is usually not allowed

[0075] (Schematic structure of the ultraviolet irradiation system)

[0076] FIG. 1 is a schematic configuration diagram of an ultraviolet irradiation system 1 according to a first embodiment of the present invention.

[0077] As shown in FIG. 1 , the ultraviolet radiation system 1 according to the first embodiment of the present invention is composed of a light source device 200 and a curing reaction detection device 100, wherein the light source device 200 is used for radiation curing ultraviolet ray 54, and the curing ultraviolet ray 54 is used for The curing reaction of the ultraviolet curable resin is promoted, and the curing reaction detection device 100 is used to detect the curing reaction of the ultraviolet curable resin when it receives ultraviolet rays for curing. Furthermore, the ultraviolet irradiation system 1 is disposed, for example, on a production line in which the adherend 8 is disposed on the base material 6 and the two are bonded together using an ultraviol...

Abstract

The invention provides an ultraviolet irradiation apparatus, curing reaction detector used for the same and method for curing an ultraviolet curing resin using the curing reaction detector. The measured fluorescence amount and a previously set threshold value alpha 1 are compared and when the measured fluorescence amount exceeds the threshold value alpha 1 , a message such as 'curing reaction completion' is issued. Note that when this 'curing reaction completion' is issued, an irradiation end instruction is given to a light source part from a curing reaction detector, and irradiation of a curing ultraviolet ray is stopped. Along with the stop of the curing ultraviolet ray, the irradiation of an exciting ultraviolet ray is also stopped.

Description

technical field [0001] The present invention relates to an ultraviolet irradiation system for curing ultraviolet curable resins, a curing reaction detection device used in the system, and a curing method for ultraviolet curable resins using the ultraviolet irradiation system, in particular to a method for judging ultraviolet curable resins in real time The technology of the curing reaction state. Background technique [0002] In recent years, an ultraviolet curing method (Ultra Violet Curing) has been adopted as a curing method for adhesives and coating agents in many industrial fields. Compared with the thermal curing method that uses heat energy, the ultraviolet curing method has many advantages such as no harmful substances released into the atmosphere, short curing time, and can also be applied to heat-sensitive products. [0003] In the ultraviolet curing method, an ultraviolet curable resin is used which is mainly liquid before ultraviolet ray irradiation but becomes ...
