Description

UV curing machine using LED {ULTRA VIOLET CURE APPARATUS USING A LED}

The present invention relates to an ultraviolet curing machine, and more particularly, to an ultraviolet curing machine using LEDs.

Ultraviolet ray paints are increasingly used due to environmental friendliness, economical efficiency, workability and productivity improvement, and energy saving effects. These ultraviolet paints are characterized by ultraviolet (UV) curable materials. 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, the conventional lamp type ultraviolet curing machine cannot obtain high illuminance because of the wide angle of the lamp, and therefore, it takes a long time to cure the curable material. In addition, a lot of heat is released because the lamp must be illuminated for a long time, and other problems are caused by the heat.

Secondly, when optical coating is performed with a thin PET or PVC film using a conventional lamp type UV curing machine, there are increasing companies that suffer from many problems due to thermal 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.

Third, the conventional lamp type ultraviolet curing machine cannot obtain uniform hardness characteristics because the illuminance is different for each position of the object to be cured by a wide orientation angle.

The present invention has been proposed to solve the above-described problems, and to provide a UV curing machine using an LED, the lens is attached to the top of the LED mounted on the substrate as a technical problem.

UV curing machine using an LED according to the present invention for achieving the above technical problem, at least two LEDs, the substrate on which the LEDs are mounted, the light condensing lenses mounted on the LEDs, respectively, and the An optical unit including a cylinder lens mounted on the condenser lenses to cover the condenser lenses; A radiator supporting the substrate and dissipating heat generated from the substrate to the outside; And a cover covering the radiator and the optical unit.

The present invention attaches a condensing lens to each of the upper ends of the LEDs mounted on the substrate, and condenses the light output from the LEDs in a predetermined direction, thereby providing an effect of narrowing the directing angle of the light.

In addition, the present invention provides an effect that the illuminance of the light output from the ultraviolet curing machine can be uniformly formed at each position by mounting a cylinder lens on top of the condenser lenses.

UV curing machine 10 using the LED according to the present invention, as shown in Figure 1, by outputting the ultraviolet ray on the surface of the product 20 is coated with the ultraviolet paint, to cure the ultraviolet paint, As shown, at least two LEDs 120, a substrate 110 on which the LEDs are mounted, and condensing lenses 130 mounted on top of the LEDs, respectively. And an optical unit 100 including a cylinder lens 140 mounted on top of the condenser lenses to cover the condenser lenses, a radiator for supporting the substrate and dissipating heat generated from the substrate to the outside. And a cover 400 covering the radiator and the optical unit. On the other hand, although not shown in the drawings, the UV curing machine using the LED according to the present invention may include a control unit. That is, the controller performs a function of controlling the driving of the optical unit 100 to allow the present invention to cure the ultraviolet paint applied to the product 20.

First, the radiator 200 is to emit heat generated by the LED 120 and transferred to the substrate 110 to the outside, and may be formed of an air-cooled radiator 231 or a water-cooled radiator. This air-cooled radiator may be formed integrally with the cover. The water-cooled radiator has a tube formed therein through which cool refrigerant can flow.

Next, the cover 400 is to form the appearance of the ultraviolet curing machine using the LED according to the present invention, it may be connected to the radiator 200 as shown in FIG. The cover 400 may be formed in various shapes to form a box shape. A rectangular through hole 410 is formed in an output surface on which the light emitted from the LEDs 120 is output among the surfaces of the cover 400.

The optical unit 100 is mounted in an inner space formed by the cover 400 and the radiator 200. That is, the substrate 110 of the optical unit 100 is mounted on the plane of the inner space formed by the cover 400 and the radiator 200 through a screw or the like, the cylinder lens 140 of the optical unit, On the output surface where the through hole 410 is formed, it is supported by the cover.

Lastly, the optical unit 100 performs a function of generating ultraviolet rays for curing the ultraviolet paint, and as described above, the LEDs 120, the substrate 110, and the condenser lens 130. And a cylinder lens 140.

The substrate 110 is mounted to the radiator 200 through a fastening means such as a screw. A plurality of LEDs are mounted side by side on the substrate 110, and a plurality of condensing lenses 130 are mounted side by side to surround each LED.

The LED 120 is a kind of semiconductor device that allows electricity to flow in a forward direction and does not flow in a reverse direction. The LED 120 emits light by recombination of minority carriers (electrons and holes) injected using a PN junction structure of a semiconductor. do. That is, the LED 120 emits light when a constant voltage is applied in the forward direction. The LED 120 has a light emitting efficiency because it is smaller than a conventional lamp, has a long lifetime, and electrical energy directly changes into light energy. In addition, LEDs are characterized by price competitiveness and high luminous efficiency. On the other hand, the wavelength of the LED may be variously changed depending on the characteristics of the ultraviolet ray paint and the degree of curing.

The condenser lens 130 condenses the light output from each LED 120 in the direction in which the cylinder lens 140 is formed. To this end, as shown in FIG. 4, the condenser lens 130 is formed in a concave shape, and a convex lens 130d is formed at the center of the convex lens, and is formed of a transparent material. The upper end 130c, the main body 130b supporting the upper end 130c, and the lower end of the main body 130b to support the main body and to be attached to the substrate 110. ) Is included. That is, the condenser lens 130 condenses the light output from the LED 120 to the cylinder lens 140 disposed on the condenser lens.

The cross section in the vertical direction of the main body portion 130b constituting the condensing lens 130 is formed to be rounded so that the upper end portion is wider than the lower end portion to guide the light output from the LED to the upper end portion 130c. It is. Therefore, the light emitted from the LED 120 disposed below the main body 130b is introduced into the main body through the bottom of the main body 130b and then directed upward along the inner surface of the main body 130b. Can be.

The support part 130a constituting the condensing lens 130 is formed with at least three support parts, and the support parts are mounted on the substrate while surrounding the LEDs. That is, the support 130a does not simply perform the function of mounting the condenser lens 130 on the substrate, but rather surrounds the LED. In this way, the light output from the LED is not dispersed to the outside of the condensing lens, and as described above, may be introduced into the main body through the lower end of the main body and guided toward the upper end of the main body. In addition, the light guided to the upper direction of the main body portion may be guided toward the cylinder lens 140 in a focused state through the upper end 130c.

The upper end portion 130c constituting the condensing lens 130 has a circular shape, and the upper end surface constituting the circular shape has a concave shape toward the center direction. Therefore, the light guided to the upper end 130c through the main body 130b may be focused toward the upper end of the condenser lens by the upper end formed in the concave shape. However, when the entire surface of the upper end 130c is formed in a concave shape, a focus is formed at the upper end of the condensing lens 130, so that the light passing through the upper end may be focused on the focus. Therefore, in order to prevent this, the convex lens 130d is formed at the central portion of the upper end 130c. That is, the light entering the upper end through the main body and passing through the upper end by the concave upper end 130c and the convex lens 130d formed convexly in the middle thereof is focused on the upper end of the upper end 130c. As a result, the focus is not formed. On the other hand, of the upper end portion 130c forming a circle, both side surfaces 130e facing each other are cut parallel to each other. This is to bring the plurality of condenser lenses 130 mounted on the substrate to be in close contact with each other. That is, the condensing lenses 130 may be mounted on the substrate in a more intimate state by being mounted on the substrate such that the cut side surfaces 130e face each other. In addition, since the condensing lenses 130 are in close contact with the side surface 130e as described above, the condensing efficiency of the condensing lens may be increased. Meanwhile, not only the upper end 130c but also the side surfaces of the main body 130b in contact with the side surface 130e may be cut in the same manner as the side surface 130e.

The cylinder lens 140 is supported by the cover 400 on the output surface on which the through hole 410 is formed, and has a cross section cut in a direction perpendicular to the longitudinal direction of the cylinder lens. A semicircular shape is formed, and the semicircular rounded portion is mounted to the cover 400 to be disposed in a direction facing the condensing lenses 130.

 The cylinder lens 140 evenly spreads the light collected through the condenser lens 130 to the upper end of the condenser lens on the output surface on which the through hole 410 is formed. That is, the light collected at the lower end of the cylinder lens 140 by the condenser lens 130 forms a point light source under the influence of each condenser lens 130. However, in order to be used as a light source of the curing machine, such a light source must be evenly distributed on the output surface. To this end, the present invention is to mount the cylinder lens 140 on the condenser lens 130, so that each point light source collected through the condenser lens 130 is changed to a surface light source form. That is, each point light source collected through the condenser lens is changed into a surface light source while passing through the cylinder lens 140, and is emitted to the outside through the through hole 410.

To this end, the cylinder lens 140 is formed such that a cross section cut in a direction perpendicular to the longitudinal direction of the cylinder lens has a semicircular shape, and the semicircular rounded portion faces the condensing lenses 130. It is attached to the cover to be disposed in the viewing direction.

That is, as shown in Figure 3, the upper end surface of the cylinder lens 140 is a plane, the lower end of the cylinder lens 140 is formed to be round in a semi-circular shape. The lower end of the semicircular shape is in close contact with the condensing lenses 130.

Therefore, the point light sources collected by the condenser lens 130 are introduced into the lower end of the semicircular cylinder lens 140, and then are reflected by the inner surfaces of the cylinder lens while being led to the upper end of the cylinder lens. In an evenly distributed state, it may be output through the top surface.

In detail, the condensing lens 130 performs the function of condensing the light output from the LED 120 on an upper end of the LED, and the cylinder lens 140 is formed by the condensing lens 130. The light condensed in the form of a light source is distributed evenly on the output surface.

Therefore, the ultraviolet rays output by the present invention as described above are evenly distributed over the entire output surface. For this reason, this invention can obtain uniform illuminance on the whole output surface. In addition, since the ultraviolet rays output by the present invention as described above are condensed and dispersed in the output plane direction by the condensing lens 130 and the cylinder lens 140, the ultraviolet rays form a narrow directivity angle. Doing.

Therefore, the present invention may have excellent curing performance than the conventional ultraviolet curing machine.

Third, the present invention has the feature that can reduce the carbon dioxide emissions.

Fourth, the present invention has the characteristics that the direct illuminance and the uniformity can be improved by using the condenser lens 130 and the cylinder lens 140 as described above.

It can be designed to satisfy.

Fifth, the LED applied to the present invention can maintain a lower temperature than the UV lamp, generate a low power consumption (KW class), can be used in the Low PW Consumption method, and has a lifetime of 10,000 ~ 50,000 hours It is an eco-friendly material, and has a feature of short lamp warm up time (Instanteous on / off). In addition, the LED applied to the present invention is characterized by low heat and single band WL.

Sixth, the present invention has a feature that there is no film heat deformation because there is no hot wire, and since no heat is generated at all, the bubble problem can be solved mostly, and thus an improvement in adhesive strength can be expected.
