Typically, a high-pressure UV lamp 112 is used, and the high-pressure UV lamp 112 used is a high-pressure mercury lamp (Hg UV LAMP), a metal lamp (METAL LAMP), and a gallium lamp (Gallium Lamp) .

A high-pressure mercury lamp is a lamp that encloses a high-pressure mercury vapor of 1 to several atmospheric pressure inside a light emitting tube, discharges between the two electrodes to emit light, and contains argon gas at a wavelength of 320 to 420 nm, ultraviolet It emits blue green by line spectrum. It has high starting voltage due to high vapor pressure in the arc tube, takes a long time to start, but has a long life and a large light speed per lamp.

The metal lamp has a structure similar to that of a high-pressure mercury lamp and has a characteristic of broadening the main wavelength from 370 nm to 380 nm by adding a metal (Fe-based) based on a mercury lamp with a wavelength of 320 to 420 nm. Cargo is a lamp that radiates continuous ultraviolet light, generating metal-specific light when decomposed by metal atoms and halogen atoms.

The Gallium Lamp is a lamp having a wavelength of 420 nm and purple color, and a gallium (Ga) base is added to the mercury lamp to move the main wavelength to near 403 nm and 417 nm.

High-pressure mercury lamps are generally used for coating, drying, curing, adhesion, printing processes for coatings and curing thicknesses of less than 10 microns. Metal lamps are generally used for thick coatings over 15 microns and thick coatings for curing, Since the gallium lamp is suitable for curing thick paints or coating liquids of 30 microns or more, the type of the UV lamp 112 is determined according to the purpose of use.

The lamp housing 114 includes a cold mirror, a hot mirror, and a dual structure lamp house for cooling.

A cold mirror reflects ultraviolet light (200nm ~ 380nm), visible light (381nm ~ 650nm) and transmits infrared light (651nm ~), and acts as a reflector.

Reflectors are mirrors that reflect ultraviolet rays (254nm, 365nm, 405nm, 436nm) and transmit visible light and infrared rays. They are used in low-temperature applications and can be coated on flat, elliptical, spherical and cylindrical outer surfaces.

50 to 70% of the ultraviolet rays emitted from the UV lamp 112 are radiated toward the reflection gods. Therefore, when the reflection gods are selected, it is determined that ultraviolet rays should be used in the condensing type or parallel reflection type as needed.

Depending on the type of reflector, the reflection efficiency and the curing efficiency of the creature are different depending on the type of reflector. Determine the type of reflector according to the characteristics of the creature.

Convergence type focusing ultraviolet light in one place is most commonly used for UV curing machine. The diffusion type UV reflector which diffuses UV light is lossy and the parallel light type reflector which reflects UV light in parallel is suitable for UV curing machine and the like.

The hot mirror has a spectral characteristic opposite to that of a cold mirror, and transmits visible light and reflects infrared light. And a UV filter for transmitting ultraviolet rays to reflect visible light.

By using a cold mirror and a hot mirror, heat (infrared rays) is emitted to the outside when the UV lamp 112 emits light, and the ultraviolet reflection effect is maximized, thereby preventing deformation of the created object.

Since the high-pressure UV lamp 112 of the lamp housing 114 generates high heat due to light emission, it is designed to maximize the cooling efficiency from the lamp housing 114 in consideration of the irradiation efficiency and cooling, do.

The cooling system is a forced air-cooling system that simultaneously performs intake and exhaust, and also forms a structure that the intake air surrounds the exhaust air, so that an air curtain film can be formed between the heating part and the creature, minimizing the interference with the heat of the creature, It is possible to prevent the lifting phenomenon.

The operation of the irradiating apparatus 100 and the pressurizing apparatus 200 through the mechanical sensor is performed by sensing the sensors (not shown) installed at predetermined positions of the rails 195 while moving the respective apparatuses on the rails 195 do.

When a predetermined position on the rail 195 of each of the devices is determined and the position is determined by the mechanical sensor, each position signal is calculated by each operation signal to perform predetermined operations according to the position.

For example, when the irradiating apparatus 100 driven by the manipulator 140 comes close to the creature, the sensing unit on the rail 195 installed at the point where the end of the creature is located is moved to the lower end of the irradiator 120, 128) is detected, and the position signal is converted into the operation signal.

The irradiation height is determined by the height varying section 116 by the input operation signal and a predetermined operation is performed at a specific position such as the irradiation of the irradiation device 110 is started.

Although the irradiation height and the pressing height of the irradiation device 100 and the pressing device 150 and the movement and the movement of the irradiation device 110 and the pressing roller device 160 are adjusted by the mechanical sensor in this embodiment, As a matter of course, it is a matter of course that a suitable known measuring element can be applied to the change of the height of the irradiation and the pressurization.
