Description

[0001] UV IRRADIATION DEVICE [0002]

The present invention relates to a UV irradiation apparatus used for curing, and more particularly, to a UV irradiation apparatus used for curing, in which a light emitting unit is provided at the center in the longitudinal direction of a housing so that a light source can be irradiated, A plurality of water-cooling members provided on the reflector so as to improve the efficiency of the air circulation by air circulation through the air supply center of the conventional air supply center or the exhaust air center, and a heat radiation unit So that it is more effective to maintain the plasma stabilization inside the lamp gap by cooling more quickly and uniformly. In addition, the stable plasma can stabilize the UV light and improve the UV irradiation quality. And more particularly to a UV irradiation apparatus which is excellent in curing quality by strengthening the cooling efficiency so as to be easy to use in a long arc.

In general, maintaining a constant lamp tube wall temperature in a UV irradiation apparatus is a technology that greatly affects lamp life and UV emission. In addition, a large amount of electric energy is converted to UV light by about 20%, and the remainder is converted into heat. If this heat management is not successful, the lamp life is shortened, or blackening or whitening occurs on a part of the lamp, which is why the light uniformity does not come out well. In addition, heat dissipation means for cooling the lamp is necessary to prevent the lamp from causing a malfunction when the lamp is overheated.

Such conventional technology is disclosed in Korean Utility Model Registration No. 20-0282156 entitled " Chiller Cooling System of UV Curing Machine "

In the conventional art, a cooler is separately provided on the outside of the body of the ultraviolet ray curing device to connect with a cooler in the body to produce cold air that has been doubly cooled. The method of injecting the cool air into the drying chamber includes, in addition to a conventionally used conveyor lower inlet, A cold air inlet tube having a plurality of injection holes in the direction of the UV lamp may be installed on the circumferential wall of the drying chamber or a partition for injecting cold air may be provided between the UV lamps as a bottom cover, or a jet body may be provided between the UV lamps, The cold air in the cold air room is injected into the drying room by various methods such as forming a cold air blowing hole in the downward and lateral directions thereof or installing a corrugated pipe connected to the air conditioner in the upper part of the drying room, The fan is installed and controlled by the control box dedicated to the cooling system. And a chiller cooling system of an ultraviolet light curing machine which maintains the characteristics according to the characteristics.

However, the above-mentioned prior art suggests a technique of naturally curing a product by simply supplying UV light and cold air by supplying cold air to a drying chamber which is cured by using a UV lamp using an external cooler.

Also, as a conventional technique, there is a " UV curing device equipped with a heat sink ", which is registered in Korean Patent No. 10-1464355,

The conventional technique includes a conveyor belt for conveying a cured object, a plurality of rollers for moving the conveyor belt, a frame supporting the rollers, a frame having a first frame hole and a second frame hole, A lower plate of the intermediate plate, which is fastened to the frame and is fixed to the frame and is formed with an intermediate plate lower hole, and a lower plate formed on the upper side of the frame And a second space connected to the second frame hole and to which a second ventilation device is mounted and an upper second outlet is formed, so that the heat transferred to the conveyor belt and the intermediate plate passes through the heat sink, The present invention proposes a UV curing device which is emitted to the outside.

However, in the related art, the heat dissipation effect using the heat dissipating plate is limited because it is a technique of cooling the heat using the heat dissipating plate, and it is difficult to expect an excellent heat dissipating effect.

In addition, there is a prior art No. 10-0847520 entitled " edge exposure apparatus for substrate "

The prior art includes a chamber provided with a reflector for reflecting light generated from the lamp to the bottom,

A cooling chamber for keeping the temperature raised by the reflector and the reflector constant, and a cooling chamber provided below the cooling chamber

A pair of second reflection mirrors for reflecting the light transmitted from the second reflecting mirror in a downward direction,

A pair of lenses for condensing the transmitted light, and a condenser for condensing the condensed light,

And a light source control unit for transmitting light to the edge. The lamp has an edge exposure apparatus for a substrate in the form of a rod installed in the longitudinal direction.

However, the conventional technique reduces the heat of the heat sink due to the water-cooled circulation pipe, which is also excellent in reducing the heat of the heat sink, but can not directly reduce the heat of the lamp, and thus the heat can be overheated.

In addition, there is a conventional UV-LED apparatus having a public-type cooling means, as disclosed in Japanese Patent Application Laid-Open No. 10-2015-0089100,

The above-described conventional technique has a UV-LED unit comprising a plurality of UV-LED modules, an LED mounting part for mounting the UV-LED unit, and a first fluid passage having an inlet and an outlet between the LED mounting part, And an air supply means for supplying air to the inlet of the first fluid passage, the heat sink being disposed at the rear of the LED mounting portion to discharge heat transferred from the LED mounting portion to the outside air, LED device.

However, the above-mentioned prior art is configured to have a heat radiating effect by forming a fluid passage in the heat radiating plate to supply cool air. Such a cool air indirectly takes heat and reduces the heat of the heat radiating plate, it's difficult.
