Abstract
Description
TECHNICAL FIELD The present invention relates to an ultraviolet curing machine, and more particularly, to an ultraviolet curing machine having a line beam using an LED.
Ultraviolet paints are increasingly used due to their environmental friendliness, economical efficiency, workability, productivity, and energy savings. The ultraviolet paint has a feature of ultraviolet (UV) curable material. That is, the ultraviolet ray paint means a material which undergoes a photochemical reaction by the energy of ultraviolet rays (100 to 400 nm) and cures from a liquid phase to a solid phase. The ultraviolet ray paint has characteristics that the reaction time and physical properties of the coating film are changed depending on the relationship with the ultraviolet ray curing machine. Such UV paints and UV curing machines are widely used not only for the production of large furniture and flooring materials, but also for the production of home appliances such as semiconductors and mobile phones.
On the other hand, the conventional ultraviolet curing machine generally uses a lamp. Many users of such lamp-type UV curing machines have many problems such as thermal deformation, reduced productivity, increased tack time, reduced quality, and poor adhesion. These problems are as follows.
First, when the optical coating with a thin PET or PVC film using a conventional ultraviolet curing machine, there are an increasing number of companies that suffer from many problems due to heat deformation. That is, in the conventional lamp type ultraviolet (UV) curing machine, when the ultraviolet lamp (UV lamp) is turned on, not only ultraviolet (UV) but also a lot of heat is emitted. Since the internal temperature of the UV lamp is as high as 4500 degrees, the heat from the lamp is very strong. The heat transfer at this time is conduction, convection, and radiant heat, which causes the temperature of the product to rise rapidly. The temperature rise of the product varies depending on the number of lamp kW, the number of lamps, the speed of the conveyor, and the material of the product.However, since the internal temperature of the lamp is higher than 4500 ° C, the product passing under the lamp must receive heat unconditionally. When heated, there are bound to be various types of defects.
Second, the conventional ultraviolet curing machine is used to cure the ultraviolet paint using only ultraviolet light having one wavelength. However, among the ultraviolet paint, the contact portion in contact with the product and the portion except the contact portion may have different curing characteristics. Therefore, when curing the UV paint using a conventional UV curing machine having only one wavelength, the degree of curing at each part may be different, in particular, the curing at the contact portion between the UV paint and the product may be poor. have.
The present invention has been proposed to solve the above problems, and provides a line beam UV curing machine using LEDs, in which two kinds of light emitting diodes (LEDs) having different wavelengths are arranged to face each other at a predetermined angle. It is technical problem to do.

And a cover having a rectangular through hole, wherein the LEDs arranged in the optical part of the first module and the LEDs arranged in the optical part of the second module generate light having different wavelengths. The LEDs arranged in the optical section of one module have a wavelength of 365 nm, and the LEDs arranged in the optical section of the second module have a wavelength of 385 nm or 405 nm.
The present invention can solve problems such as heat deformation, reduced productivity, and reduced quality, which have been generated in the conventional ultraviolet curing machine.

However, the wavelength of the LED applied to the present invention is not limited to the wavelength as described above. That is, the wavelength of the LEDs provided in the first module and the second module may be changed in various ways depending on the characteristics of the ultraviolet paint and the degree of curing.
Lastly, as described above, the
For example, the
In detail, each of the first surface of the first module (surface of the optical unit 120) and the first surface of the second module (surface of the optical unit 220) may be perpendicular to the output surface. It is connected to the
The reason why the first module and the second module are configured as described above is to increase the intensity of light by collecting the ultraviolet rays emitted from the respective optical units. That is, the present invention, by arranging the first module and the second module in the inclined state as described above, the light emitted from the LEDs on the curing target surface (surface of the product) disposed at the focal length of the LEDs mounted on each module Can be collected in the form of a beam to generate very high irradiation intensity.
That is, the present invention is characterized in that the two wavelengths emitted from the two modules are inclined at a constant angle so that the two wavelengths can be collected at the focal length point where the light intensity is the highest.
Because of this, the present invention can have a curing time within a very short time, for example within 5 seconds, and thus can cure the desired irradiation area for a short time. That is, as the light is collected as described above, the irradiation intensity of the ultraviolet light is increased, thereby, the curing time of the cured product is shortened quickly, and the production efficiency can be improved.
In addition, as shown in Figure 5, the UV curing machine according to the present invention is configured to enable a uniform line-shaped beam irradiation by arranging a pair of LED modules in a row so as to be controlled as a unit by a control controller, respectively Half the price of conventional UV curing heads and 200mw / cm 2 light intensity Above, BEAM UNIFORMITY more than 80%, irradiation area is 5mm * 500mm or more, the curing time can be exhibited within 5 seconds.
On the other hand, the control controller, by controlling the drive of the optical unit, performs a function to allow the present invention to cure the ultraviolet paint applied to the product.
The following summarizes the features of the present invention as described above.
First, briefly summarize the features of the present invention.
The present invention relates to an ultraviolet curing machine using LED, which is capable of implementing complex wavelengths for curing, and emits ultraviolet rays by using LED, and configures a
In the conventional ultraviolet curing machine, the wavelength used for curing is a single wavelength, or a whole wavelength band not involved in curing is irradiated to generate heat or to be incompatible with a resin or an adhesive. However, the present invention greatly improves the conventional uncured problems and heat dissipation by implementing dual wavelengths (365 nm, 385 nm) or (365 nm, 405 nm). Through this, the present invention can increase the production efficiency of the cured product, it is possible to improve the construction and cost reduction of the environment-friendly production line.
Second, the present invention provides an effect that can solve problems such as heat deformation, productivity decrease, quality deterioration that occurred in the conventional ultraviolet curing machine.
That is, while the conventional UV curing machine of the UV lamp type generates a lot of heat, the present invention does not generate heat at all. In addition, since the present invention is 5-50 times stronger in UV intensity, the number of UV curing machines required to cure the same product can be reduced. Since the UV intensity is more than 10 times stronger and the number of curing devices (the same concept as the number of UV lamps) is reduced, there is almost no heat transferred to the product, and all the problems generated in the conventional UV curing machine can be solved. That is, not only the thermal deformation problem, but also most problems with the technique of UV curing can be solved by the present invention.
Third, the advantages of the present invention are as follows.

The present invention not only compensates for the shortcomings of the conventional UV Lamp, but also solves the problems of UV LED curing machine products which are currently commonly used. That is, since the ultraviolet light-emitting diode (UV LED) curing machine currently generally used hardens a product using only a single wavelength, such as 365 nm or 385 nm, in many cases, it is not compatible with resin or an adhesive agent. However, since the present invention implements dual wavelengths (365 nm, 385 nm) or (365 nm, 405 nm), the problem of not being cured as in the prior art can be solved.
The present invention is composed of an optical cylinder lens and an asymmetric aspherical lens, it is possible to efficiently collect the UV energy or to make a beam of the desired shape.
The present invention is excellent in heat dissipation effect by the air-cooled and water-cooled integrated heat dissipation structure.
The present invention is 50% cheaper in terms of price than the conventional UV LED curing machine, the light irradiation intensity is 200mw / ㎠ or more, the beam uniformity is 80% or more (uniformity), the irradiation area is 10mm x 500mm Above, the curing time may be within 5 seconds.
Fourth, the utilization of the present invention is as follows.
The present invention is to reduce the manufacturing cost and simplify the equipment by changing the light source of the industrial curing medium (coating, curing, etc.) or UV curing machine used for the curing of industrial products to ultraviolet light emitting diodes (UV LED), thereby simplifying the conveyor, It can be applied to the type of medium curing device.
In the case of heat deformation and temperature sensitive optical film manufacturing process such as PP, PE, PVC, PET, optical film, and lowering by only 1 ° C determines product quality and productivity, the UV curing machine according to the present invention is applied to such a manufacturing process. Can be.
In addition, the present invention is applicable to medical DNA and protein UV analysis equipment.

It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
