Applying the ultraviolet ray to aforementioned work in

摘要

PROBLEM TO BE SOLVED: To provide an ultraviolet irradiation device and ultraviolet irradiation method capable of reducing consumption energy of the entire process by effectively using energy such as an infrared ray which has been wasted conventionally when ultraviolet is irradiated to cure with respect to a workpiece with lower heat resistance, and capable of preventing damage on the workpiece from occurring.;SOLUTION: The ultraviolet irradiation device includes: a light source 31 for emitting the light including at least the ultraviolet; a first reflection member 31 which reflects the ultraviolet emitted from the light source 31 to the workpiece W side to form a first irradiation area on the workpiece W, and causes the light with the wavelength longer than the ultraviolet to penetrate; and a second reflection member 32 which reflects the light with the wavelength longer than the ultraviolet penetrating the first reflection member 31 to the workpiece side to form a second irradiation area on the workpiece. The second irradiation area is formed separately in the upper stream with respect to the predetermined direction D rather than the first irradiation area.;COPYRIGHT: (C)2013,JPO&INPIT
