The present invention relates to a method for forming a pattern on the glasses and to a method for manufacturing the same, more specifically, a pattern, including a design required by the customer to create a more value-added product to avoid the monotonous pattern and color of the glasses It is about editing photos and pictures using a computer, and editing the edited patterns on a flatbed printer, and then editing the pictures and pictures on a computer with the colors and pictures that the customer wants, and then forming colors and patterns on the desired positions.

As a method of forming a pattern on the spectacle frame, a method of using screen printing, transfer, a water repellent, or the like is used. However, a large number of colors are used to form a complex picture and photo, and the process of forming a pattern in proportion to the number of colors is complicated.

In the case of screens, complex shapes such as pictures and photographs require as many screen meshes and work processes as multicolored colors. This is the cause of bad factors and price increases. In addition, adhesion failure occurs due to the lack of compatibility with the plastic material after screening.

In the case of transfer, multicolor colors can be realized on printing paper, but it takes 20 to 30 seconds at a temperature of 150 degrees or more to transfer patterns printed on surface layers of plastic and metal. This causes the deformation and aging of the spectacle frame, which results in instability of dimensions and quality when mounted on the actual product.

In the case of a veterinary company, printing is possible, but its physical properties are avoiding its use as a material that has problems with attachment for use in glasses.

In addition, in the case of printing with a conventional flatbed printer, agglomeration or spreading of the ink occurs due to the surface tension of liquid ink, and thus it is difficult to realize a picture and a picture of a desired shape.

Therefore, a technique for outputting a pattern on a material having a coating layer formed thereon regardless of a plastic or metal material of eyeglass frames will be required.

A first object of the present invention for solving the above problems is to provide a coated glasses formed with a coating layer expressed by ink spraying a computer-edited picture and photos with a flatbed printer.

In addition, a second object of the present invention is to provide a method of manufacturing coated glasses in which a pattern and a picture output to a flatbed printer are formed to form a coating layer in order to achieve the first object.

The present invention for achieving the first object, the spectacle frame made of synthetic resin or metal; A first coating layer formed on the spectacle frame; A printing layer formed on the first coating layer before drying or semi-curing of the first coating layer; And a coating layer formed on the printing layer and including a second coating layer for protecting the printing layer.

The present invention for achieving the second object, forming a frame of synthetic resin material; Polishing and cleaning the eyeglass frame; Forming a first coating layer on the spectacle frame; Forming a printing layer on the first coating layer before drying or semi-curing the first coating layer; Forming a second coating layer on the printed layer to protect the printed layer; And drying the spectacle frame on which the first coating layer, the printing layer, and the second coating layer are formed.

In addition, the second object of the present invention, forming a metal frame eyeglass frame; Polishing and cleaning the eyeglass frame; Plating the eyeglass frame; Forming a first coating layer on the spectacle frame; Forming a printing layer on the first coating layer before drying or semi-curing the first coating layer to prevent spreading and agglomeration of the ink; Forming a second coating layer on the printed layer to protect the printed layer; And drying the spectacle frame on which the first coating layer, the printing layer, and the second coating layer are formed, wherein the printing layer edits computer-designed patterns, photographs, and pictures, and ink through a nozzle using a flatbed printer. It can also be achieved through the provision of a method for manufacturing a coated glasses, characterized in that formed by spraying.

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

First Example

1 is a cross-sectional view showing a coating layer on which a picture and a photo are output by computer editing on a spectacle frame according to a first embodiment of the present invention.

Referring to FIG. 1, first, a printing of a buffer layer 200, a first coating layer 300, and a computer-edited pattern and color on a spectacle frame 100 made of metal or synthetic resin is output to a flatbed printer. The layer 400 and the second coating layer 500 which protects the printed layer are sequentially formed. However, according to the exemplary embodiment, the buffer layer 200 may be selectively interposed. The first coating layer 300 and the second coating layer 500 is composed of a pigment and a paint.

As the paint, acrylic paint, urethane paint, epoxy paint, acrylic urethane synthetic paint, UV cured paint, and the like are used.

FIG. 2 is a flowchart illustrating a method of forming a coating layer by outputting a picture and a photo edited by a computer to a flat plate printer on a spectacle frame of plastic material according to an embodiment of the present invention.

2 and 1, first, the synthetic frame is molded to form the spectacle frame 100 (S100). In order to mold the spectacle frame 100, a synthetic resin is added to a mold, and then a conventional plastic spectacle frame manufacturing process is performed.

In addition, when the molding of the spectacle frame 100 is completed, polishing and cleaning are performed (S110). The polishing and cleaning is performed as a preliminary work for forming the first coating layer 300 on the spectacle frame 100.

Polishing removes protruding parts or foreign matter during molding. Preferably the cleaning is carried out after the polishing process. Cleaning is performed to remove foreign matter or synthetic resin powder remaining on the surface of the spectacle frame 100 by a polishing process. In particular, when the synthetic resin powder formed by polishing remains on the surface, the adhesion of the mixed coating is lowered, so the cleaning process uses a wet cleaning process. That is, the glasses frame 100, which has been polished, is completely precipitated in the cleaning solution, and foreign substances or synthetic resin powder on the surface of the glasses frame is removed using ultrasonic waves.

After the cleaning is completed, the spectacle frame is mounted on a jig and spray coating is performed. There are two ways to perform spray coating on the spectacle frame.

First, a buffer layer 200 is formed on an eyeglass frame (S120), and then a first coating layer 300 is formed on the buffer layer 200 to prevent spreading and agglomeration of ink (S130). The buffer layer 200 is used to improve the adhesion between the first coating layer 300 and the spectacle frame 100, and also the first coating layer due to the difference in the coefficient of thermal expansion between the spectacle frame 100 and the first coating layer 300. It is for preventing the phenomenon that 300 is peeled off from the spectacle frame 100.

The buffer layer 200 uses a thermosetting resin, and preferably epoxy resins, urethane resins, acrylic resins, acrylic urethane synthetic resins, UV curing paints, etc., depending on the type of resin. In addition, the buffer layer 200 is preferably formed by mixing the resin with a volatile solvent such as thinner or alcohol and spray coating in a solution state.

After the buffer layer 200 is formed, the first coating layer 300 is formed (S130).

Formation of the first coating layer 300 is based on spray coating. That is, the paint and the organic solvent are mixed, and the mixed solution is sprayed onto the spectacle frame to form the first coating layer 300. The formed first coating layer 300 is cured before curing or semi-cured to prevent spreading and agglomeration of the ink.

As the paint, acrylic paint, urethane paint, epoxy paint, acrylic urethane synthetic paint, UV cured paint, and the like are used. The paints are used in one or two parts. One-part paint refers to forming a layer with only the paint and drying it. Two-part paint refers to mixing the paint and the curing agent to perform faster curing by the action of the curing agent.

Therefore, the first coating layer 300 made of paint is formed.

In addition, in the present embodiment, the second method of forming the first coating layer 300 on the spectacle frame 100 is to form the first coating layer 300 directly on the spectacle frame 100 where the cleaning process is completed (S130). Such a case is greatly affected by foreign matter on the surface of the spectacle frame, and thus high precision is required in the polishing and cleaning process.

That is, the paint and the organic solvent are mixed, and the mixed solution is sprayed onto the spectacle frame to form the first coating layer 300 (S130). Since only the solvent is volatilized or the drying process until the semi-cured state (S160) is completed, the first coating layer 300 is composed of paint only.

When the first coating layer 300 is formed by the two methods described above, a process for forming the printed layer 400 is performed (S140). In the present invention, the print layer 400 is formed by printing a picture and a photo edited by a computer directly on the surface of the first coating layer 300 using a flatbed printer. At this time, the ink can be any ink as long as it can be sprayed by the nozzle of the printer, regardless of the oil ink, water ink, transfer ink, pigment ink, dye ink. In this case, the first coating layer 300 supporting the print layer 400 maintains the pre-cured state or the semi-cured state in which the organic solvent is volatilized.

When the printing layer 400 is formed by the above-described method, a process for forming the second coating layer 500 is performed (S150). The second coating layer 500 is formed of a transparent layer in which no pigment is added to the paint as a protective layer against discoloration and external impact of the ink, or a translucent layer in which a small amount of the pigment is added to the paint. Formation of the second coating layer 500 is according to the spray coating. That is, the coating material and the organic solvent are mixed, and the mixed solution is sprayed on the printing layer 400 to form the second coating layer 500. In addition, when the semitransparent layer is to be formed, a method of mixing a pigment and an organic solvent in a paint and spraying the mixed solution on the printing layer 400 may be used.

As the paint, acrylic paint, urethane paint, epoxy paint, acrylic urethane synthetic paint, UV cured paint, and the like are used. The paints are used in one or two parts. One-part paint refers to forming a layer with only the paint and drying it. Two-part paint refers to mixing the paint and the curing agent to perform a faster curing by the action of the curing agent.

Thus, the second coating layer 500 including the paint is formed. In particular, the paints used for the first coating layer 300 and the second coating layer 500 may be divided into natural drying paints, baking drying paints, cooling solidification paints, catalytic curing paints, ultraviolet curing paints or electron beam curing paints according to a drying method. Can be.

Natural drying paint is a paint that is dried without any external force in a natural state, and a baking paint is dried by applying heat. In addition, the cooling hardened paint is dried by cooling of the paint, and the catalyst hardened paint uses drying using a catalyst. In addition, the ultraviolet curable paint to dry the coating by irradiation with ultraviolet rays, the electron beam curable paint is to dry the paint using an electron beam.

Preferably, the paint is a baking dry paint. As the above-mentioned dry paint, the thermosetting resin is used as above-mentioned, and it heats and it dries, and it is excellent in rust prevention ability, and can form a beautiful appearance by forming a hard and uniform film quality. Therefore, the pigment is mixed with the baking coating and spray-coated to form a coating layer. The calcined dry paint is a melamine-based, acrylic or fluororesin-based.

When the second coating layer 500 is formed, a drying process is performed (S160).

Thus, pictures and photographs edited by a computer are formed on a plastic spectacle frame including a coating layer formed by ejecting ink by a nozzle using a flatbed printer.

2nd Example

3 is a flowchart illustrating a method of forming a coating layer by outputting a picture and a photo edited by a computer to a flat plate printer on a metal frame according to a second embodiment of the present invention.

Referring to FIG. 3, the metal material is cut and pressed to form a metal frame of the metal material (S200). In addition, the uniformity of the surface of the spectacle frame is increased by polishing (S210).

Subsequently, a plating process is performed on the spectacle frame (S220). In the plating process, it is preferable to perform nickel plating on the first plating and the first plating on the surface of the spectacle frame. In addition, nickel plating may be used as the primary plating, and chromium plating may be secondarily formed on the nickel plating formed as the primary.

In the case of the initial plating, a phenomenon in which the plating layer is peeled off due to surface uniformity may occur by directly forming a metal layer on the surface of the spectacle frame by polishing. Therefore, it is preferable to use nickel plating or chromium plating after the initial plating.

After the plating process is completed, the spectacle frame is mounted on a jig and spray coating is performed. Spray coating on the spectacle frame is divided into two methods.

The method of claim 11, wherein the adhesion between the first coating layer and the eyeglass frame is improved between forming the eyeglass frame and forming the first coating layer, or a difference in thermal expansion coefficient between the eyeglass frame and the first coating layer. And forming a buffer layer to prevent the first coating layer from peeling off.

First, a buffer layer 200 is formed on an eyeglass frame (S225), and then a first coating layer 300 is formed on the buffer layer 200 to prevent spreading and agglomeration of ink (S230). The buffer layer 200 is used to improve the adhesion between the first coating layer 300 and the spectacle frame 100, and also the first coating layer due to the difference in the coefficient of thermal expansion between the spectacle frame 100 and the first coating layer 300. It is for preventing the phenomenon that 300 is peeled off from the spectacle frame 100. The buffer layer 200 uses a thermosetting resin, and preferably epoxy resins, urethane resins, acrylic resins, acrylic urethane synthetic resins, UV curing paints, etc., depending on the type of resin.

In addition, the buffer layer 200 is preferably formed by mixing the resin with a volatile solvent such as thinner or alcohol and spray coating in a solution state.

After the buffer layer 200 is formed (S225), the first coating layer 300 is formed (S230).

Formation of the first coating layer 300 is based on spray coating. That is, the paint and the organic solvent are mixed, and the mixed solution is sprayed onto the spectacle frame to form the first coating layer 300. The formed first coating layer 300 is cured before curing or semi-cured to prevent spreading and agglomeration of the ink.

As the paint, acrylic paint, urethane paint, epoxy paint, acrylic urethane synthetic paint, UV cured paint, and the like are used. The paints are used in one or two parts. One-part paint refers to forming a layer with only the paint and drying it. Two-part paint refers to mixing the paint and the curing agent to perform a faster curing by the action of the curing agent.

In addition, in the present embodiment, the second method of forming the first coating layer 300 on the spectacle frame 100 is to form the first coating layer 300 directly on the spectacle frame 100 on which the cleaning process is completed (S230). Such a case is greatly affected by foreign matter on the surface of the spectacle frame, and thus high precision is required in the polishing and cleaning process.

That is, the paint and the organic solvent are mixed and the mixed solution is sprayed onto the spectacle frame to form the first coating layer 300 (S230). After the solvent is only volatilized or the drying step to the semi-cured state (S260) is completed, the first coating layer 300 is composed of a paint.

When the first coating layer 300 is formed by the two methods described above, a process for forming the print layer 400 is performed (S240). In the present invention, the print layer 400 is formed by printing a picture and a photo edited by a computer directly on the surface of the first coating layer 300 through a flatbed printer. At this time, the ink may be any ink, ink, water, transfer ink, pigment ink, dye ink can be sprayed by the nozzle of the printer. In this case, the first coating layer 300 supporting the print layer 400 maintains a state before curing or a semi-cured state in which the organic solvent is not completely volatilized.

When the printing layer 400 is formed by the above-described method, a process for forming the second coating layer 500 is performed (S250). The second coating layer 500 acts as a protective layer against discoloration and external impact of the ink, and is formed as a transparent layer without a pigment or a translucent layer with a small amount of the pigment. Formation of the second coating layer 500 is according to the spray coating. That is, the coating material and the organic solvent are mixed, and the mixed solution is sprayed on the printing layer 400 to form the second coating layer 500. Moreover, in order to form a translucent layer, you may use it, mixing a pigment and an organic solvent with paint. When the second coating layer 500 is formed, a drying process is performed (S260).

As the paint, acrylic paint, urethane paint, epoxy paint, acrylic urethane synthetic paint, UV cured paint, and the like are used. The paints are used in one or two parts. One-part paint refers to forming a layer with only the paint and drying it. Two-part paint refers to mixing the paint and the curing agent to perform a faster curing by the action of the curing agent.

In particular, the paints used for the first coating layer 300 and the second coating layer 500 may be divided into natural drying paints, baking drying paints, cooling solidification paints, catalytic curing paints, ultraviolet curing paints or electron beam curing paints according to a drying method. Can be.

Natural drying paint is a paint that is dried without any external force in a natural state, and a baking paint is dried by applying heat. In addition, the cooling hardened paint is dried by cooling of the paint, and the catalyst hardened paint uses drying using a catalyst. In addition, the ultraviolet curable paint is irradiated with ultraviolet light to dry the paint, the electron beam curable paint is to dry the paint using an electron beam.

Preferably, the paint is a baking dry paint. As the above-mentioned dry paint, the thermosetting resin is used as above-mentioned, and it heats and it dries, and it is excellent in rust prevention ability, and can form a beautiful appearance by forming a hard and uniform film quality. Therefore, the pigment is mixed with the baking coating and spray coating to form a coating layer. The calcined dry paint is a melamine-based, acrylic or fluororesin-based.

Thus, pictures and photographs edited by a computer are formed on a metal eyeglass frame including a coating layer formed by ejecting ink by a nozzle using a flatbed printer.

According to the present invention, the printing layer formed by the flatbed printing is formed when the first coating layer is in the pre-cured state or the semi-cured state. When the printed layer is formed while the first coating layer is completely cured, bleeding or agglomeration of ink occurs and a predetermined pattern cannot be smoothly formed on the first coating layer. When the first coating layer is in the semi-cured state, bleeding phenomenon of the ink forming the printing layer does not occur, and in the subsequent process, the hardening of the first coating layer together with the hardening of the first coating layer results in a sharper pattern in close contact with the first coating layer. Can be formed.
