Problems solved by technology

When the irradiation target is located at a position corresponding to an irradiation distance other than the specified irradiation distance, the ultraviolet rays from the head are irradiated on the irradiation target in a state deviated from the focus (that is, in a defocused state), and there is The problem of not being able to irradiate in the optimal irradiation state
In addition, when aligning the focal point at a position corresponding to an irradiation distance other than the specific irradiation distance, it is necessary to replace it with a condenser lens having a focal length corresponding to the irradiation distance, so it is necessary to prepare lenses with various focal lengths. There is a problem that the cost required for the ultraviolet irradiation device increases due to multiple condenser lenses

Abstract

The present invention provides an ultraviolet irradiation device that can easily adjust the focus at the irradiation distance.Ultraviolet irradiation device (2) has the head (4), and the power control department for light control control to the head (4).Head (4) has: light emitting diode (8), which illuminates ultraviolet rays; the first installation agency (10), the installation of the light emitting diode (8); the concentration lens (12), the gathering of the light emitting diode (8) illuminationUltraviolet rays; second installation agencies (14), the installation of conservation lens (12); cylindrical outer body (16), which maintains the first installation mechanism (10) and the second installation agency (14);18), it is used to regulate the spacing distance between the light -emitting diode (8) and the concentrated lens (12), and the distance between the interval between the adjustment mechanism (18) to make the first installation mechanism (10) in the interior of the tube -shaped external body (16)Axial movement.

Description

technical field [0001] The present invention relates to an ultraviolet irradiation device for curing an ultraviolet curable resin. Background technique [0002] For example, ultraviolet curable resins have been conventionally used for bonding components such as optical lenses, and an ultraviolet irradiation device for curing the ultraviolet curable resins has been used (for example, refer to Patent Document 1). This ultraviolet irradiation device includes a head that irradiates ultraviolet rays, and a power control unit that controls lighting of the head. The head has a light emitting diode for irradiating ultraviolet light, a first mounting mechanism for mounting the light emitting diode, a condenser lens for collecting ultraviolet rays irradiated from the light emitting diode, and a second mounting mechanism for mounting the condenser lens. The first mounting mechanism and the second mounting mechanism are fixed to each other by, for example, fixing screws or the like, th...
