The present invention relates to an illumination device for inspection using a non-lens ultraviolet LED.

Generally, when producing products such as shoes, adhesives are used to attach rubber products such as outsole. Prior to applying the adhesive, the primer is applied. The primer serves to help the adhesive be evenly applied. Such a primer should be applied thinly and evenly, and then the operation of applying the adhesive can be performed without fail.

Therefore, it is necessary to inspect whether the primer is evenly applied to the whole area to be coated. However, since the primer is generally transparent or has a weak color, it is difficult to visually check whether or not the primer is well applied even after application.

Conventionally, an inspection apparatus for irradiating ultraviolet rays was used to inspect the application state of the primer. As an inspection device for generating ultraviolet rays, conventionally, an inspection device including a general fluorescent lamp with a filter for passing only ultraviolet rays or an ultraviolet fluorescent lamp for generating ultraviolet rays has been used.

However, when the quality of the primer-coated state is inspected using ultraviolet rays, there is a problem that ultraviolet rays are exposed to the worker and adversely affect the human body of the worker.

Since the ultraviolet rays are harmful to the human body, a specially designed UV lens may be used to narrow the irradiation angle of ultraviolet rays to prevent the ultraviolet rays from reaching the human body. However, the special UV lens has a problem in that the manufacturing cost is increased due to a large manufacturing cost, the amount of ultraviolet rays absorbed while passing through the lens is reduced, and the amount of ultraviolet rays reaching the object to be inspected is reduced.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Like parts are designated with like reference numerals throughout the specification.

Hereinafter, the inspection illumination device using the non-lens ultraviolet LED according to the embodiments of the present invention will be described in detail.

An illumination device for inspection using a non-lens UV LED according to embodiments of the present invention is a lighting device for inspecting a coating quality state of a primer containing a fluorescent material in a coating material and reacting with ultraviolet rays. The primer is a pretreatment liquid and is applied before the adhesive is applied to the adhesive surface of the adherend such as the shoe sole, thereby helping the adhesive to be evenly coated. However, the quality evaluation object of the present invention is not limited to the primer applied to the shoe sole but can be used in general liquid coating agents, phosphors, forgery discrimination, and the like.

The illumination device for inspection using the non-lens ultraviolet LED according to the first embodiment of the present invention will be described with reference to Figs. 1 and 2. Fig.

FIG. 1 is a perspective view of an inspection illumination device using a non-lens UV LED according to a first embodiment of the present invention, and FIG. 2 is a side view of an inspection illumination device using a non-lens UV LED according to the first embodiment of the present invention to be. Referring to FIGS. 1 and 2, the inspection illumination device using the non-lens UV LED according to the first embodiment of the present invention includes an inspection illumination using a non-lens UV LED for inspecting the application state of a primer responsive to ultraviolet rays An LED lamp 20, a white LED lamp 30 and a reflector 40. The base plate 10, the LED lamp 20,

The base substrate 10 is a plate-shaped member and is a member on which a UV LED lamp 20 and a white LED lamp 30 are mounted. . The base substrate 10 may be formed of plastic made of a synthetic resin material, or may be formed of a metal material.

Although not shown, when a large amount of heat is generated during operation of the UV LED lamp 20 and the white LED lamp 30, a heat sink may be provided on the base substrate 10. The heat radiating plate may be formed of an aluminum material. When the heat radiating plate is provided, the heat radiating from the UV LED lamp 20 and the white LED lamp 30 is emitted to the outside, Thereby preventing the problems caused by the heating of the circuit and each lamp.

The UD LED lamp 20 is provided on one side of the base substrate 10. At least one UV LED lamp 20 may be provided on one surface of the base substrate 10, and a plurality of UV LED lamps 20 may be spaced apart from each other according to the length of the base substrate 10. The UV LED lamps 20 may be arranged in a line in the longitudinal direction of the base substrate 10, but they may be arranged in a zigzag shape, and may be arranged at different intervals, but may be different from each other. That is, the arrangement state of the UV LED lamp 20 can be freely selected according to the indoor environment and the use environment in which the inspection illumination device using the non-lens UV LED according to the embodiment of the present invention is to be installed.

The UV LED lamp 20 may have a wavelength range of 260 to 420 nm.

Ultraviolet rays are classified into UV-A (320 to 400 nm), UV-B (280 to 320 nm) and UV-C (100 to 280 nm) depending on their wavelengths. In general, UV-A is used for counterfeit discrimination, UV-B is used for inspection equipment, and UV-C is used for sterilization and deodorization. Since the inspection illumination device using the non-lens ultraviolet LED according to the embodiment of the present invention may be used for various inspections, it is necessary to emit all three types of ultraviolet rays, and the wavelength range of the ultraviolet rays emitted varies depending on the purpose of use . For example, when the present invention is used in counterfeit discrimination and the like, a UV LED lamp that emits a wavelength region corresponding to UV-A can be used. When a reaction material reactive with ultraviolet rays having a wavelength of 300 to 350 nm is to be inspected, A UV LED lamp that emits ultraviolet rays in the range of ~ 350 nm can be used.

The white LED lamp 30 is disposed on the other surface of the base substrate 10 and disposed in a direction opposite to the LED lamp 20 with respect to the base substrate 10. The arrangement of the white LED lamps 30 may be arranged at equal intervals as in the case of the LED lamps 20 but may be arranged in a line along the longitudinal direction of the base substrate 10 However, it can be arranged in various shapes such as a zigzag shape or an irregular shape as necessary.

The reflector 40 is installed on one side of the base substrate 10 to surround the UV LED lamp 20. At this time, the center of the cross section of the reflection plate 40 may be located on the same line as the center of the cross section of the base substrate 10.

1, the reflector 40 may be long in one direction along the longitudinal direction of the base substrate 10. However, if necessary, a plurality of lamps 20 may be installed in correspondence with the number of the UV LED lamps 20 in a shape that surrounds the UV LED lamps 20. The width of the reflection plate 40 may be longer than the width of the base substrate 10 and may be formed to be similar to the width of the base substrate 10 corresponding to the width of the base substrate 10 as necessary.

The reflector 40 may be any one selected from the group consisting of aluminum, silver, titanium, platinum, and palladium.

When the ultraviolet rays emitted from the UV LED lamp 20 are refracted or reflected by using a lens, since the ultraviolet rays are absorbed by the lens, the intensity of the ultraviolet rays reaching the subject is weakened and the inspection efficiency is lowered. However, when a reflective plate made of a metal such as aluminum is used as in the embodiment of the present invention, most of the light emitted from the UV LED lamp 20 can be utilized without absorbing ultraviolet light, thereby increasing the accuracy of the inspection.

The UV LED lamp 20 provided on the base substrate 10 emits light toward the reflection plate 40 and the light is refracted by the reflection plate 40 and directed downward.

The reflection plate 40 can refract the direction of the light emitted from the UV LED lamp 20 to change the direction of the light so that the angle of the ultraviolet light irradiated to the subject can be adjusted within a range of about 10 degrees.

The irradiation angle? Described in the present invention is an angle formed by the progress direction line of light after the ultraviolet ray is refracted by the reflector 40 when the vertical line of the bottom surface of the base substrate 10 is set as the reference line.

The reflection angle of the reflection plate 40 can be adjusted by the radius of curvature of the reflection plate 40 provided on the base substrate 10, and the like. For example, the end surface of the reflector 40 may have a parabolic or equivalent structure so that ultraviolet light reflected from the UV LED lamp 20 may be refracted at a narrow irradiation angle.

When the irradiation angle of ultraviolet rays is larger than 10 degrees, ultraviolet rays may be exposed to the skin of a person to be inspected of the subject in addition to the subject, and it may be harmful to the human body.

3 is a side view of an inspection illumination device using a non-lens ultraviolet LED according to a second embodiment of the present invention. Referring to FIG. 3, the inspection illumination device using the non-lens UV LED according to the second embodiment of the present invention has a configuration different from that of the first embodiment in the shape of the reflection plate 40, Do.

The valleys of the reflection plate 40 are formed at positions corresponding to the base substrate 10. The ultraviolet light reflected by the UV LED lamp 20 is reflected by the reflection plate 40 and is refracted downward. That is, as described in the present embodiment, the shape of the reflection plate 40 is not limited to a simple parabolic shape, and it is possible to refract the irradiation angle [theta] of the ultraviolet ray reflected by the UV LED lamp 20 within 10 DEG It can be replaced with another shape.

Therefore, only the different configurations will be described, and the configurations and operation effects not described will be applied to the same or similar modifications as those described in the preceding embodiments.

The reflector 40 is provided on the other surface of the base substrate 20 so as to surround the base substrate 10 and the UV LED lamp 20. The center of the cross section of the reflection plate 40 is offset to one side with respect to the center of the cross section of the base substrate 10.

4, one surface of the base substrate 10 on which the UV LED lamp 20 is disposed is inclined at an angle of more than 0 DEG and less than 90 DEG with respect to the other surface of the base substrate 10 have. In this case, ultraviolet rays reflected by the UV LED lamp 20 are directed to the diagonal direction reflection plate 40, and ultraviolet rays reaching the reflection plate 40 are refracted by the reflection plate 40 and directed downward.

The angle of the one surface of the reflector 40 and the base substrate 10 may be adjusted so that the irradiation angle of the ultraviolet light reflected by the UV LED lamp 20 can be controlled within 10 degrees. In other words, the radius of curvature of the reflection plate 40 is designed to correspond to the angle of the base substrate 10 on which the UV LED lamp 20 is installed, so that the irradiation angle? .

5 is a side view of a lighting device for inspection using a non-lens ultraviolet LED according to a fourth embodiment of the present invention. 5, the illumination device for inspection using the non-lens ultraviolet LED according to the fourth embodiment of the present invention is different from the first embodiment in the shape of the base substrate 10, same. Therefore, only the different configurations will be described, and the configurations and operation effects not described will be applied to the same or similar modifications as those described in the preceding embodiments.

Unlike the above-described embodiment, the base substrate 10 of this embodiment is not a flat plate but has a polygonal cross-section. Therefore, the side surface of the base substrate 10 is inclined at an angle of more than 0 DEG and less than 90 DEG with respect to the bottom surface of the base substrate 10. Both side surfaces of the base substrate 10 may be formed such that the inclined angles around the bottom surface are the same and are inclined at different angles from each other.

And a UV LED lamp 20 is provided on a side surface of the base substrate 10. The UV LED lamp 20 may be formed on both sides of the base substrate 10, as shown in FIG. However, in the case where the base substrate 10 is biased to one side with respect to the reflection plate 40, the LED lamp 20 may be formed only on one side of the base substrate 10.

On the bottom surface of the base substrate 10, a white LED lamp 30 is provided. The white LED lamp 30 is provided on the bottom surface of the base substrate 10 and reflects light downward.

The reflector 40 is connected to the upper side of the base substrate 10, unlike the embodiment described above. In this case, the radius of curvature of the reflection plate 40 can be designed in consideration of the reflection angle of the ultraviolet ray so that the irradiation angle of the ultraviolet ray reflected from the UV LED lamp 20 can be controlled within 10 degrees.

Meanwhile, in the illumination device for inspection using the non-lens ultraviolet LED according to the embodiment of the present invention, a switch part may be further connected to the base substrate 10 or the reflection plate 40.

The switch unit may selectively light one of the UDY lamp 20 and the white LED lamp 30 or the UDY lamp 20 and the white LED lamp 30 at the same time.

The inspection illumination device using the non-lens ultraviolet LED according to an embodiment of the present invention may be configured such that only the UV LED lamp 20 is lit or the white LED lamp 30 is lit when necessary . In this case, there is an effect that it is not necessary to prepare a separate inspection tool for inspecting the inspected object. Further, when the white LED lamp is lit in the same manner, there is an advantage that the irradiation can proceed in a bright environment.

When the inspected object is not inspected, only the white LED lamp 30 is turned on and used as illumination. In this case, since the UV LED lamp 20 is not turned on, the electricity can be saved.

Further, a bulb 50 may be further provided on the other side of the base substrate 10. The bulb 50 is a member that protects the white LED lamp 30 and allows light emitted from the white LED lamp 30 to pass therethrough. The bulb 50 may be formed of a lens material or may be formed of a general transmissive glass.

The bulb 50 for protecting the white LED lamp 30 may be individually provided in each white LED lamp 30 and may be formed to be long along the longitudinal direction of the base substrate 10 like the reflection plate 40 Can be. When the bulb 50 is formed as long as the reflector 40, the bulb 50 is formed to have a small width corresponding to the area of the base substrate 10 so as not to interfere with the transparency of the light emitted from the LED lamp 20 . When the bulb 50 is formed corresponding to the white LED lamp 30 so as to surround each white LED lamp 30, the bulb 50 may be provided on the base substrate 10, or alternatively, And may be provided on the surface of the white LED lamp 30 as required.

Hereinafter, the operation and effect of the illumination device for inspection using the non-lens ultraviolet LED including the above-described configuration will be described.

In the inspection illumination device using the non-lens ultraviolet LED according to the embodiment of the present invention, when inspecting the inspection object of the inspection object, the inspection target can be inspected by turning on the UV LED lamp 20. At this time, the working environment may be dark or the white LED lamp 30 may be turned on simultaneously as needed.

Since the UV LED lamp 20 is disposed toward the ceiling with the base substrate 10 as a center, ultraviolet rays are emitted toward the ceiling. The radiated ultraviolet rays reach the reflection plate 40, are refracted and refracted downward, and ultraviolet rays reach the subject. At this time, the angle of irradiation is adjusted to be within about 10 degrees by the reflector 40 so that most ultraviolet rays reach the subject and do not touch the human body.

Since ultraviolet rays are refracted by the reflection plate 40, ultraviolet rays are not absorbed when refracted, unlike when refracted by a lens, so that most of the ultraviolet rays emitted from the UV LED lamp 20 reach the subject and the inspection accuracy is excellent It will be canceled.

When ultraviolet rays reach the object to be inspected, ultraviolet rays have a property of causing fluorescence emission of the liquid material applied to the surface of the substance, so that it is possible to evaluate the coating quality of the primer or the like on the subject depending on whether or not the fluorescent light is emitted.

When the inspection is completed, the illumination of the UV LED lamp 20 is turned off using only the switch unit and only the white LED lamp 30 is turned on to perform other general process operations, or the operator can perform other operations as needed.

Accordingly, the white LED lamps 30 and the LED lamps 20 can be selectively turned on according to need, so that the brightness of the working environment can be easily controlled and the electricity can be saved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, Of the right.
