本発明は強紫外線を用いて光硬化性接着剤を硬化させる
紫外線照射装置において、紫外線の漏れ防止に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to prevention of leakage of ultraviolet rays in an ultraviolet irradiation device for curing a photocurable adhesive using strong ultraviolet rays.

めに搬送用のベルトコンベアー上のワークに紫外線を照
射して連続的に硬化処理を行っている。UV-curable adhesives have traditionally been used as adhesives or fixing agents for lead wire extraction parts of optical components such as lenses and prisms, and electronic components such as ICs, and have been used to improve workability. Therefore, the workpieces on the conveyor belt are continuously hardened by irradiating them with ultraviolet rays.

すのである。FIG. 5 is a schematic explanatory diagram showing a conventional ultraviolet irradiation device.
3 is a conveyor belt, 3 is an ultraviolet lamp, and 2 is a light shielding plate. In such ultraviolet irradiation devices, the ultraviolet rays are often reflected by the surface of the belt conveyor 1 and leaked to the outside from the openings of the light shielding plate 2 and the conveyor belt (light rays P). For this reason, there was a concern that it would have an adverse effect on the eyes of workers. As a countermeasure to this problem, a lid 4 as shown by the broken line in the figure has been attached to the exposed portion of the belt conveyor, but this poses a problem in terms of workability. That is, the lid must be opened and closed every time a workpiece is placed on or taken off the belt conveyor, resulting in a decrease in work efficiency.

くしたものである。Kouji (7)”L! The present invention is an ultraviolet irradiation device that irradiates ultraviolet rays from above a belt conveyor that continuously conveys works such as optical components coated with a photocurable adhesive. This is to reduce the leakage of ultraviolet rays.
皇−１−週 以下、実施例によって本発明を具体的に説明する。Emperor-1-week Hereinafter, the present invention will be specifically explained with reference to Examples.

照射されることにより、接着剤を硬化させるのである。FIG. 1 is a schematic cross-sectional view showing a first embodiment of the present invention, in which 1 is a conveyor belt, 2 is a light shielding plate, and 3 is an ultraviolet lamp, which is coated with a prefabricating adhesive. The workpieces, such as lenses and prisms, are placed on a belt conveyor 1 and conveyed continuously, and the adhesive is cured by being irradiated with ultraviolet light by an ultraviolet lamp 3.

光板７とよりなる多重遮光装置を設けたものである。2 is the light-shielding plate mentioned above, but in order to further reduce the light P reflected from the surface of the belt 1 and leaking from the light-shielding plate 2 and the opening of the entrance/exit of the belt converter, the skirt part of the light-shielding plate is fitted as shown in the figure. Inner light shielding plate 6. A multiple light-shielding device is provided, which includes an external light-shielding plate 7 as an auxiliary light-shielding plate.

７は通電の反射防止処理が施されていることは勿論であ
る。The light shielding plate 2 also serves as a covered cylindrical lamp housing, and a donut-shaped space is formed by multiple light shielding devices provided on the skirt portion. Therefore, the ultraviolet rays P leaking from the light shielding plate 2 and the entrance/exit opening of the belt conveyor are absorbed by the surface of the light shielding plate by being repeatedly reflected on the inner surface of the outer light shielding plate (auxiliary light shielding plate) 7 and the outer surface of the inner light shielding plate. This reduces the amount of leakage to the outside. In addition, the light shielding plate 6.
7 is of course subjected to anti-reflection treatment when energized.
また、第２図に示すように本実施例の外側遮光板（補助
遮光板）７の外側に更に遮光８を重ねることにより更に
遮光効果を高めることができる。Further, as shown in FIG. 2, the light shielding effect can be further enhanced by layering a light shield 8 on the outside of the outer light shield plate (auxiliary light shield) 7 of this embodiment.
重ねる補助遮光板の数は必要に応じて増せば、それだけ
遮光効果が高まるわけであるが、照射装置の大きさや実
用上の点からみて数枚程度が適当である。If the number of auxiliary light-shielding plates to be stacked is increased as necessary, the light-shielding effect will be increased accordingly, but in view of the size of the irradiation device and practical considerations, it is appropriate to use only a few sheets.

うち、光線密度が最も大きい角度と垂直に交わる角度に
傾けである。FIG. 3 shows a second embodiment of the present invention, in which the outer light shielding plate (auxiliary light shielding plate) in the first embodiment is tilted. Reference numeral 7a indicates the tilted outer light shielding plate, and since the other parts are the same as those in the first embodiment, the explanation will be omitted. a is an angle that intersects perpendicularly to the angle at which the light beam density is the highest among the leaked and reflected light P.

部を通過した光は、傾いた外側遮光板（補助遮光板）７
ａにより、その大部分が入射方向に反射されることにな
るので、第１実施例よりも更に遮光効果が大きい。Therefore, the light passing through the opening between the inner light shielding plate 6 and the belt conveyor l is transmitted to the inclined outer light shielding plate (auxiliary light shielding plate) 7.
Since most of the light is reflected in the incident direction by a, the light shielding effect is even greater than that of the first embodiment.
更に、遮光効果を高めるためには、第１実施例で説明し
たように、補助遮光板を多重にすればよい。Furthermore, in order to enhance the light shielding effect, the auxiliary light shielding plates may be multiplexed as described in the first embodiment.

This light-shielding plate has a structure in which the skirt portion of the light-shielding plate 2 has a bellows-type multiple light-shielding device in cross section, as shown by reference numeral 9, and has the same effect as that shown in FIG.
