Description

Detailed Description of the Invention: Industry 1- Utilization/3 Fields Invention d, Ultraviolet rays used when performing botting seals, coatings, adhesion, etc. using photochromic resins [1, (((irradiation) Regarding equipment/) 6゜Conventional configurations and their problems In recent years, botting agents, sol agents, and Ni-no-Denogu have been used in a wide range of areas including light electrical equipment, optical equipment, equipment, and 9. As an agent or adhesive, it can be used for a long time or a short time.
,(/,:'t',i') Ultraviolet 61Jj-curing resins, which do not require cleaning the environment, are increasingly being used4.

Hereinafter, a conventional ultraviolet 11 device for irradiating such ultraviolet curable resin with ultraviolet rays will be described.

In Fig. 1, 1d is a cover to prevent ultraviolet 411 of the entire device, 2 is a 1'1□'', pressurized mercury plate that emits ultraviolet rays, 3a is a concave reflector that focuses all of the ultraviolet rays, and 4 is a nyatter. 6 is '/ Yatsuta opening/closing cylinder, 6゜γ
8 is a curing part, 8 is a stand for parts 6 and 7, and 9 is a part 6.
Norinder for supplying and extracting γ, 10 (r:j two ultraviolet ray sealing materials, 11V'1 glossy 112!d, base of the entire device, 18 is a support column for ultraviolet rays [1 ( The operation of the irradiation device will be explained below. 3. Sunzu high-pressure mercury lamps 2 to 11 (The irradiated ultraviolet rays are focused downward by the anti-pulling plate 3a. Next, parts 6 and 7 are assembled. The support is mounted on the stand 8 and inserted into the housing using the cylinder 9. Next, the shutter 4 is opened using the cylinder 5 and the entire parts 6 and 7 are irradiated with ultraviolet rays to harden the photocurable resin. At this time, the shutter material 10, the shutter 11, and the cover 1 completely prevent the leakage of ultraviolet rays to the outside when the shutter 4 is opened.

However, in the above conventional configuration, the sealing material 10, the shutter 11, and the metal side cover 1 for the entire device are used to prevent leakage of ultraviolet rays.
This requires a complicated mechanism, which increases the size of the entire device, and has the disadvantage that the entire part is irradiated with ultraviolet rays, which causes the irradiation of ultraviolet rays in unnecessary places, which can have a negative impact on the parts.

Purpose of the Invention The present invention solves all of these conventional problems, has a simple configuration, and irradiates ultraviolet rays to the required spots in a spot-like manner. The overall purpose is to provide an α-shooting device.

Structure of the Invention The present invention consists of a high-pressure mercury lamp for ultraviolet irradiation, a reflector for concentrating ultraviolet rays, an inner cover with all slotted holes that serve as a guide when sliding under the reflector, and a JQ board. It has an outer cover with a torsion guide elongated hole that lowers while rotating the outer surface, and depending on the rotational position of the inner surface -h...- and the outer tlfi-i cover, it can be used from the ultraviolet irradiation hole provided on the double force bar. Ultraviolet rays are irradiated in spots only to the necessary areas, and UV rays II (2) are used to cover the entire high-pressure mercury lamp and reflector to prevent ultraviolet rays from leaking to the outside. - Figure 4 does not show the ultraviolet irradiation hole @ in one embodiment of the present invention.In Figure 2, 2 is a high-pressure mercury lamp that irradiates ultraviolet rays, 3b is a concave reflector plate that condenses ultraviolet rays, Reference numeral 13 denotes an inner cover having a long hole 13a that slides and guides the inner surface of the reflector 3b in the vertical direction and a hole 13b for ultraviolet irradiation on the lower surface, and 14 a twist guide elongate hole that unifies while rotating the outer surface of the reflector 3b. 142L is an outer cover having a hole 14b for ultraviolet irradiation on the lower surface. 15 is a guide pin fixed to the reflector 3b that guides the inner cover 13 and the outer cover 14, and is combined with a bearing 16. 17 is a 7 is the IFFJ turning lever of the outer cover 14, a cradle for holding the J4% products 6 and 7, 9 is a loader for taking out the parts 6 and 7, 12 is the base of the entire device, and 18 is a support. be.

The operation of the ultraviolet curing apparatus of this embodiment configured as described above will be explained below.

In Figure 2, the ultraviolet light irradiated by the high-pressure mercury lamp 2
! (The light is condensed downward by the side pull plate 3b. Next, the parts 6 and 7
The receiver is mounted on the stand 8, inserted into the surface of the ultraviolet irradiation device using the cylinder 9, and when the rotary lever 17 is turned counterclockwise, the outer cover 14 is twisted and the elongated hole 14a serves as a gold guide and the guide pin 16 is inserted. It is lowered by the bearing 16 while rotating α0, and the receiver covers the entire parts 6 and 7 of the table 8-to. The inner cover 13 also slides in the vertical direction as a guide for the elongated hole 13a'i by means of the guide pin 15 and the bearing 16, and descends by its own weight.

As shown in FIGS. 2 and 4, when the inner cover 13 and outer cover 14 are in the upper row, the ultraviolet 11α radiation hole 13b
, 14b, the rotation angle of the outer cover 14 is shifted by α0, so the holes 13b, 14b do not overlap and the ultraviolet rays do not emit 1 m, but when descending as shown in FIG. coincide with each other, and the ultraviolet rays are irradiated in spots on the ultraviolet curable resin coated parts of the parts 6 and 7, thereby curing the resin. Next, when the lever 17 is rotated α0 clockwise, the outer cover 14 rises by -L, and the inner cover 13 also rises along with it. 1, the ultraviolet ray irradiation holes 13b and 14b are shifted and there is no leakage of irradiation.

As described above, according to this embodiment, the ultraviolet rays can be set arbitrarily depending on the overlapping condition of the ultraviolet irradiation holes 13b and 14b, and the ultraviolet rays can be set arbitrarily in accordance with the overlapping condition of the ultraviolet irradiation holes 13b and 14b. Since the entire part 6.7 is covered by the grooved outer surface cover 14, there is no leakage of ultraviolet rays to the outside, and therefore conventional shutters, sealing materials, etc. can be eliminated.

In this example, the adhesive fixing metal side of parts 6 and 7 is mentioned, but even when coating or botting with ultraviolet curable resin, if the holes for ultraviolet irradiation are formed in advance according to the cured shape, it will be easier to do so. It is possible to cure the shape of.

Effects of the Invention The present invention can perform UV irradiation in any shape by combining the ultraviolet irradiation holes of the inner cover and the outer cover, and since the outer cover covers the entire article to be irradiated, the outer cover High-precision UV irradiation can be achieved with a compact and simple mechanism without any UV leakage.
