Description

[0001] COATING DESIGN COATING AND PATTERNING SYSTEM [0002]

The present invention relates to design coatings and patterning systems.

Design means choosing elements such as shape, color, material, ornament and making them aesthetic and drawing according to the use. As technology has been leveled up in modern society, the value of design combined with multifunctional attributes such as functionality, aesthetics, symbolism, and economy is continuously increasing. In addition, as the importance of design to consumers' purchasing behavior increases, companies producing products use differentiated product design as a corporate survival strategy and have devised various methods to implement it. Painting is a common way to express colors, materials, etc., which are visual elements that have an important influence on design. Painting is the painting of a fluid material such as paint or enamel on the surface of a target object, which can express various colors easily. However, since the adhesion between the object and the paint is weak, the paint is easily peeled off. Is required. Plating is mainly used in conjunction with such a painting method. Plating involves coating a thin layer with a separate material on the surface of the object, such as electroplating, dissolving metal immersion plating, spraying spraying, and the like. The purpose of the original plating is to improve the surface state of the object, but recently it has been used to make a thin layer having desired properties. Electroplating, which is the most important method of plating, can be used not only for pure metals but also for alloys, and is used in various fields. An apparatus for performing such electroplating is disclosed in the following prior art documents. A typical electroplating is to deposit a desired metal ion on the surface of an article by placing the metal to be plated as a negative electrode into an electrolyte containing metal ions to be electrodeposited with the metal to be electrodeposited as an anode and electrolyzing. Such electroplating also has some problems. First of all, there is a limit in the material to be plated and the material of the coat layer, and a long time is required for the process, resulting in low productivity. Further, it is difficult to control the color tone and the transmittance of the coating layer, so that it is also difficult to express various colors and materials.

Accordingly, there is a desperate need for a method for improving the problem of the conventional design expression method.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, detailed description of related arts which may unnecessarily obscure the gist of the present invention will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a design coating and patterning system according to an embodiment of the present invention.

1, a design coating and patterning system according to an embodiment of the present invention includes a vacuum chamber 10 in which the interior is kept in a vacuum state, a vacuum chamber 10 disposed inside the vacuum chamber 10, A crushing section 30 for crushing the solid paint to a predetermined size to produce a powder paint 3 and a powder storage section 3 for storing the powder paint 3 transported from the crushing section 30 A gas tank 50 which receives the process gas and is connected to the powder storage unit 40 by the gas pipe 51, a process unit which is disposed inside the vacuum chamber 10 and flows into the powder storage unit 40 A spray nozzle 60 for spraying the powder coating material 3 flowing by the gas in the direction of the coating material 1 and forming a coating layer 5 on the surface of the coating material 1, And a gas flow rate regulator 70 for regulating the flow rate of the process gas to adjust the color and permeability of the coating layer 5.

The design coating and patterning system according to the present embodiment is an apparatus for implementing a design by coating a powder coating material 3 on a coating material 1 and includes a vacuum chamber 10, a stage 20, a crushing unit 30, A reservoir 40, a gas tank 50, a spray nozzle 60, and a gas flow rate regulator 70.

Here, the coating material 1 is a coating object on which the coating layer 5 is formed by the powder coating material 3, and includes various objects such as a substrate, a cellular phone case, and the like. The design coating and patterning system according to the present embodiment performs the coating in such a manner that the powder coating material 3 is sprayed onto the coating material 1, and no organic solvent or water is used at all. Therefore, volatile solvent is not included, so there is little risk of poisoning by the solvent or fire, and pollution problems caused by air pollution or waste water after coating do not occur. Further, when forming the coating layer (5), there is no wrinkle or flow phenomenon, and viscosity control is unnecessary, so that the coating work is easy and efficient. Since the powder paint (3) that has arrived is almost 100% close to the coating film, it is possible to coat the back coat and it is not necessary to perform the double coating with the high performance coating film, thereby shortening the time required for the coating process. Here, the coating process is performed in the vacuum chamber 10.

The inside of the vacuum chamber 10 is maintained in a vacuum state by using a vacuum pump 11. A coating material (1) is disposed inside the vacuum chamber (10) to perform a coating process in a vacuum state. At this time, since the spraying process for spraying the powder coating material 3 on the coating material 1 proceeds at room temperature, the coating material 1 of a polymer material susceptible to heat can be used. Although the lamination behavior varies depending on the type of the coating material 1 due to the nature of the process, lamination is possible regardless of the material. Therefore, it is possible to carry out the coating process irrespective of the material such as household electric appliances in which reinforced plastic is mainly used, structural steel products, automobile steel plates, and building walls. At this time, the coated material 1 is fixed by the stage 20.

The stage 20 is a support for supporting the coated material 1 and is disposed inside the vacuum chamber 10 to fix the coated material 1 in various manners such as supporting the coated material 1 or coming in close contact with the side surface . Here, the stage 20 can move in the X-axis, Y-axis, and Z-axis directions. The three-axis movable stage 20 moves in three dimensions to realize various patterns of designs on the surface of the coated material 1.

The crushing unit 30 is an apparatus for crushing a solid paint, and produces a powder coating material 3 for forming a coating layer 5 on the coating material 1. Here, as the solid paint, for example, a ceramic having high brittleness may be used. The material is not necessarily limited to ceramics, and either a metal or a polymer may be used. It is also possible to use at least two or more of ceramics, metals and polymers as a solid coating material. The solid paint is pulverized to a predetermined size by the pulverizer 30 to become the powder paint 3. At this time, the powder coating 3 can be granulated to a submicron level, preferably to a size of 5 μm or less, so as to be aerosolized. Such an aerosolized powder coating 3 is easily coated on the coating material 1, but the size is not necessarily limited thereto.

Specifically, the crushing section 30 may be a machine for performing ball milling. At this time, the ball milling process performed by the crushing section 30 not only reduces the size of the powder coating material 3 by pulverizing the solid paint, but also applies stress in the powder particles to improve the lamination efficiency. Also, during the ball milling process, the color tone of the powder coating material 3 gradually changes to dark, and the color tone and the transmittance of the coating layer 5 can be adjusted using this color change. The powder coating material 3 produced in the crushing unit 30 is transported to the powder storage unit 40.

The powder storage part 40 is a container for storing the powder coating material 3 and is connected to the crushing part 30 by a transport pipe to store the powder coating material 3 transported from the crushing part 30. The powder coating 3 stored in the powder storage part 40 is sprayed by the process gas, which is accommodated in a gas tank 50 disposed outside the powder storage part 40.

The gas tank 50 is a container for receiving a process gas. Here, the process gas is preferably an inert gas. At this time, since the coating process is performed at a vacuum room temperature using an inert gas, the coating layer 5 can be formed by preserving the mechanical characteristics and color of the particles without additional oxidation and phase transformation of the powder coating 3 , It is relatively simple and easy to use as compared with other deposition methods. In addition, since the process speed is high, desired coatings and patterns can be formed in a short time. As the process gas, for example, helium may be used as the inert gas, but not always limited thereto, and various gases such as nitrogen, oxygen, and air may be used.

On the other hand, the gas tank 50 is connected to the powder storage part 40 by a gas pipe 51. Accordingly, the powder paint 3 flows through the gas pipe 51 by the process gas flowing into the powder storage unit 40. The powder paint 3 thus flowing is sprayed by the spray nozzle 60.

The spray nozzle 60 is a tube for spraying the powder coating material 3 and is disposed in the vacuum chamber 10 to spray the powder coating material 3 flowing by the process gas onto the surface of the coating material 1. A design pattern is realized while the powder paint 3 thus sprayed forms the coating layer 5 on the surface of the coating material 1. [ Specifically, the injection nozzle 60 has a convergent portion whose diameter or cross-sectional area becomes smaller toward the coated material 1. The powder paint 3 is sprayed together with the process gas. The process gas which has been compressed in the converging portion expands and rapidly accelerates while passing through the spray nozzle 60, and reaches the ultrasonic state, Energy. The coating layer 5 is formed as the powder coating material 3 collides with the coating material 1 due to the kinetic energy thus generated, and plastic deformation and fracture occurs at this time.

Meanwhile, the injection nozzle 60 may have various shapes such as a slit or a spherical shape. The spray nozzle 60 may be interchangeably coupled to the powder reservoir 40 so that the slit-shaped spray nozzle 60 and the spherical spray nozzle 60 may be used interchangeably.

The pressure of the process gas in the gas tank 50 may be 0.4 to 0.6 MPa. Under the pressure within this range, the speed of the powder paint 3 sprayed from the spray nozzle 60 can be easily controlled. However, the pressure of the process gas is not limited thereto. If the pressure of the process gas is excessively large, the production cost increases and the equipment becomes complicated. If the pressure of the process gas is too low, it is difficult to control the flow rate of the process gas by the gas flow rate control unit 70 described later. And can be determined appropriately. The speed of the powder paint 3 accelerated through the spray nozzle 60 can range from 150 to 600 m / s. However, it is not necessarily limited to such a speed range, but the speed of the process gas can be controlled by changing the process conditions such as the kind of the process gas and the pressure. For example, when helium is used as the process gas, the density of helium is relatively lower than other gases, so that the process gas and the powder coating 3 can be made faster and their speeds can be easily controlled. In addition, the flow rate of the process gas can be controlled to control the speed of the powder coating 3, wherein the apparatus used is the gas flow rate regulator 70.

The gas flow rate regulator 70 is mounted on the gas pipe 51 connecting the gas tank 50 and the powder reservoir 40 to regulate the flow rate of the process gas flowing along the gas pipe 51. Specifically, the gas flow rate regulator 70 may be a mass flow controller (MFC) that measures and controls the flow rate of liquid or gas. The gas flow rate regulator 70 detects the flow rate of the process gas, opens and closes the gas valve, and adjusts the flow rate of the process gas. However, the gas flow rate regulator 70 is not limited to the MFP, and includes all known controllers as long as the flow rate of the process gas can be controlled.

The gas flow rate regulator 70 adjusts the flow rate of the process gas to adjust the color and transmittance of the coating layer 5. Specifically, by controlling the flow rate of the process gas, the speed of the sprayed powder coating 3 can be controlled. For example, when the flow rate of the process gas is increased, the spraying speed of the powder coating 3 is increased. At this time, if the speed of the powder coating material 3 becomes too high, the powder coating material 3 can not form the coating layer 5 and is scattered. Therefore, it is necessary to adjust the flow rate of the process gas so that the coating layer 5 can be formed, and it is appropriate that the flow rate is about 1.0 to 20.0 L / min. However, the flow rate of the process gas is not limited thereto, and may be determined in consideration of other process conditions. The flow rate of the process gas is a factor affecting the color tone and permeability of the coating layer 5. As the flow rate of the process gas becomes larger, the speed of the powder coating material 3 becomes higher, thereby causing the coating material 1 to collide with the coating material 1 with a higher energy. At this time, since defects are generated in the particles of the powder coating material (3), the color of the coating layer (5) becomes dark and the transmittance decreases at the same time. In this way, the gas flow rate control section 70 controls the speed of the powder coating material 3 to adjust the color tone and the transmittance of the coating layer 5.

Meanwhile, the design coating and patterning system according to the embodiment of the present invention may further include a control unit 110 for controlling the gas flow rate control unit 70. The controller 110 checks the flow rate of the process gas detected by the sensor of the gas flow controller 70 and controls the gas flow controller 70 in such a manner as to adjust the opening and closing degree of the gas valve. In addition, the control unit 110 may control the valve for opening and closing the injection nozzle 60 to control the spraying of the powder coating material 3.

In general, the design coating and patterning system according to the present embodiment can be applied to the coating layer (3) through the pulverization time or size of the powder coating material 3 in the pulverizing section 30, or the flow rate control of the process gas using the gas flow control section 70 5) can be adjusted.

The color tone and the transmittance of the coating layer 5 can be adjusted not only by controlling the milling time and the size and the flow rate of the process gas but also by the speed of the stage 20, mixing of different powder coating materials 3, or heat treatment. Describe in detail.

2 is a block diagram of a design coating and patterning system according to another embodiment of the present invention.

As shown in FIG. 2, the horizontal axis movement speed of the three-axis movable stage 20 of the design coating and patterning system according to another embodiment of the present invention may be variable. Here, the horizontal axis moving speed is a speed when the stage 20 moves along the X axis or Y axis direction, and the X axis or Y axis direction is perpendicular to the direction in which the powder paint 3 is sprayed from the jetting nozzle 60 In direction. The moving speed of the coated material 1 in the lateral direction with respect to the horizontal axis moving speed of the stage 20 is related to the growth rate of the coating layer 5 and a thin and transparent coating layer 5 is formed when the horizontal axis moving speed is increased. By controlling the horizontal axis moving speed in this manner, the color and transmittance of the coating layer 5 can be adjusted.

If the distance between the spray nozzle 60 disposed in the Z axis direction of the stage 20 and the coating material 1 is excessively short, the powder coating material 3 is not coated on the coating material 1, To avoid damaging or scattering, it is necessary to maintain proper distance. Generally, a distance of about 0.5 to 15 mm is preferable, but it is not limited to this and may be determined in consideration of other process conditions and the like.

The design coating and patterning system according to this embodiment may further comprise a mixing portion 80 for mixing different powder coatings 3. The grinding units 30a and 30b and the powder storing units 40a and 40b may be a plurality of grinding units for grinding a plurality of different solid coating materials and storing a plurality of powder coating materials 3 generated therefrom. The mixing portion 80 is connected to the respective powder storing portions 40a and 40b and mixes the plurality of powder coating materials 3 in a predetermined ratio. At this time, the mixing portion 80 may include a rotating blade (not shown), or may include a powder coating 3 including a vibration device (not shown). However, the mixing process by the mixing unit 80 is not limited to the case of blades or vibrations, and mixing may be performed in various ways. By mixing various powder coating materials 3 having different sizes or colors or the like, the color and transmittance of the coating layer 5 are changed. The mixing ratio can be determined in consideration of the color and permeability of the coating layer 5 and by opening and closing the control valve 81 of the transport pipe connecting the powder storage portions 40a and 40b and the mixing portion 80 , And different powder coating materials (3) are mixed according to the ratio. Here, the control valve 81 can be automatically opened and closed by the control unit 110 as well as manually.

The design coating and system according to the present embodiment may further include a heat treatment unit 100 so that the coating layer 5 can be heat-treated. Residual stress may be generated in the coating layer 5 due to extreme deformation and breakage of the powder coating 3 during the formation of the coating layer 5. At this time, residual stress is removed through heat treatment through the heat treatment part 100, The color and the transparency of the coating layer 5 can be restored. Specifically, the heat treatment unit 100 can be disposed on the stage 20 as a heat ray, and can heat the coating layer 5 via the coating material 1 through heat transfer. However, the heat treatment unit 100 is not necessarily limited to heat rays, but includes all the heating means for applying heat to the coating layer 5, for example, a method of irradiating light with a lamp.

Meanwhile, the design coating and system according to the present embodiment may further include a pattern mask 90 to form a predetermined design pattern. Here, the pattern mask 90 is formed in a flat plate shape, and has a pattern hole 90. The pattern hole 90 is a hole formed in the pattern mask 90 with a predetermined design pattern. When the pattern mask 90 is disposed between the injection nozzle 60 and the coating material 1, the powder coating material 3 passes through the pattern hole 90 and the pattern hole 90 is formed on the surface of the coating material 1. [ The coating layer 5 is formed.

Various patterns of design can be implemented by modifying the shape of the stage 20 as well as the pattern mask 90, which will be described below.

3 is a front view of a stage of a design coating and patterning system according to another embodiment of the present invention.

As shown in FIG. 3, the stage 20 of the design coating and patterning system according to another embodiment of the present invention may rotate about at least one of the X axis, the Y axis, and the Z axis. Since the stage 20 for fixing the coating material 1 rotates, the circular or arc shape can be expressed around the rotation axis, and the coating layer 5 can be easily formed on the front surface, the rear surface, or the side surface.

Specifically, the rotatable stage 20 may include a base 21, a fixing table 23, and first and second motors 25 and 27. Here, the base 21 supports a pair of fixing bars 23 protruding from both sides of one side, and the pair of fixing bars 23 fixes one side and the other side of the coating material 1. [ The first motor 25 is disposed on the fixing table 23 to rotate the coating material 1 around the X axis to the Y axis and the second motor 27 is connected to the other surface of the base 21, 21 to rotate the coated material 1 about the Z-axis.

As described above, the design coating and patterning system according to the present invention can be applied to the coating layer 5 through the pulverization time or size of the powder coating 3, the flow rate of the process gas, the mixing of different powder coatings 3, Adjust color and transparency, and pattern the design. Hereinafter, the change in color and transmittance in each case and the patterned result are shown.

4A to 4C are photographs showing the color change of the powder coating material according to the ball milling time.

4A to 4C, white Al 2 O 3 (see FIG. 4A), red Co (Al, Cr) 2 O 4 (see FIG. 4B), blue C 9 H 13 CdN 2 O 4 SSe (see FIG. 4C) are gradually darkened in proportion to the ball milling time, respectively. This is probably due to the defect in powder paint as the ball milling time passes.

5 is a graph showing a change in the permeability of the coating layer depending on the flow rate of the process gas.

As shown in FIG. 5, as the flow rate of the process gas increases, the color of the coating layer becomes darker, and the transmittance decreases.

6 is a photograph showing the flow rate of the process gas and the change in color tone and permeability of the coating layer due to mixing of other powder coating materials.

As shown in FIG. 6, it was confirmed that the color and transmittance of the coating layer were different from each other through the mixing of the flow rate of the process gas and the powder coating material.

7 is a graph showing changes in the transmittance of the coating layer due to heat treatment.

As shown in FIG. 7, as a result of heat treatment of a coating layer without heat treatment (As-coated), a coating layer HT_1 subjected to heat treatment at 400 占 폚 for 10 minutes, and a coating layer HT_2 subjected to heat treatment for 30 minutes, And the transmittance is improved.

8 is a photograph of a patterned design on a substrate by a design coating and patterning system in accordance with an embodiment of the present invention.

As shown in FIG. 8, various designs having different colors and transmittances can be formed through the design coating and patterning system according to the embodiment of the present invention.
