Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to spectacle frames and methods for fabricating the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eyeglass frame and a method of manufacturing the same, and more particularly, to an eyeglass frame and an eyeglass frame manufacturing method using the UV printer.

In general, glasses are used for the purpose of restoring visual acuity or preventing visual deterioration. Glasses are also used to protect the eye from strong ultraviolet rays.

In recent years, eyeglasses have been used as a means of fashion, and the use of eyeglasses has been gradually diversified. As the glasses become more common for various purposes, not only the function of the glasses but also the interest of the aesthetics of the appearance of the glasses is increasing day by day.

In order to enhance the aesthetics of the appearance of the glasses, various patterns and / or colors can be added to the spectacle frame. At this time, the eyeglass frame may have various patterns and / or colors to form concavities and convexities to show the effects of negative and embossing.

In this way, injection molding, metal mold, corrosion, or CNC machining are widely used as a method of forming patterns and / or colors on the spectacle frame and showing the effects of negative and positive angles.

However, since the above methods perform processing directly on the raw material, there is a restriction that the use of colors such as 1 degree or 2 degrees is not free. Therefore, it is difficult to use colorful colors. Further, in order to use various colors, a separate follow-up work is required, so that a longer processing time is required, additional processing costs are incurred, and a defect rate is high.

In addition, methods such as screen printing, transferring or transferring are used as a method of forming a pattern and / or a color on an eyeglass frame and showing the effects of negative and positive angles.

However, in the case of screen printing, in order to print a complex shape such as a photograph, a screen network and a work step corresponding to the number of colors of multicolor are required. Therefore, there is a problem that the manufacturing cost is increased and the defect rate is high.

Transcription requires a temperature of at least 150 ° C, which can cause deformation and aging of the spectacle frame, resulting in instability of dimensions and quality when mounted on actual products. Further, in the case of a water-transferred yarn, there is a problem that it is a material which is difficult to adhere to its own properties for use in an eyeglass frame.

On the other hand, the embossed layer with patterns and / or colors is mainly located on the outermost surface of the frame. Therefore, there is a problem that the aesthetics of the glasses are drastically deteriorated due to the damage of the printed layer due to wearing of the glasses for a long time.

A problem to be solved by the present invention is to provide a coated spectacle frame which can easily and easily exhibit the effects of negative and positive effects on the spectacle frame using various patterns and / or colors, Method.

According to an aspect of the present invention, there is provided an eyeglass frame. The spectacle frame includes a frame body, a first coating layer disposed on the frame body, a second coating layer disposed on the first coating layer, a print layer disposed on the second coating layer, And a second coating layer disposed on the second coating layer.

The concavities and convexities formed on the surface of the print layer are concave and convex in embossed form, and the print layer may contain UV ink.

The frame body may be made of a metal or an alloy, and may further include a plating layer between the frame body and the first coating layer.

The frame body may be made of synthetic resin, and may further include a semi-cured coating layer between the printing layer and the third coating layer.

The semi-cured coating layer contains a second liquid coating material to which a curing agent is added, and can maintain a semi-cured state.

And an adhesive layer between the second coating layer and the print layer to improve adhesion between the second coating layer and the print layer.

The first coating layer may be an electrodeposition coating layer or a paint coating layer, and the second coating layer or the third coating layer may contain any one selected from an epoxy paint, a urethane paint, an acrylic-urethane synthetic paint, an acrylic paint, and a UV paint have.

According to an aspect of the present invention, there is provided a method of manufacturing an eyeglass frame. The method includes the steps of forming an eyeglass frame body, sequentially forming first and second coating layers on the eyeglass body, forming an adhesive layer on the second coating layer, forming concavities and convexities on the adhesive layer Forming a print layer, and forming a third coating layer on the print layer.

The print layer may be formed by using a UV printer to form a concavity and convexity by spraying UV ink only on a portion where concave and convex portions are to be formed.

The eyeglass body may be formed of a metal or an alloy, and the method may further include forming a plating layer on the eyeglass body before the step of forming the first coating layer on the eyeglass body.

The frame body may be formed of a synthetic resin and may further include a step of forming a semi-cured coating layer on the print layer between the step of forming the print layer and the step of forming the third coating layer.

At least one of the second coating layer, the adhesive layer, the semi-cured coating layer, and the third coating layer may be formed using a spray coating.

The first coating layer may be formed using an electrodeposition coating method or a paint coating method.

According to the present invention, the unevenness can be formed on the spectacle frame simply and easily by using the characteristics of the UV ink, and the effect of negative and emboss can be exhibited. That is, various complicated patterns such as colorful colors and / or gradients can be formed in the embossed form on the spectacle frame by using the UV printer only once or twice.

1 is a sectional view showing an eyeglass frame according to a first embodiment of the present invention.

Referring to Fig. 1, an eyeglass frame body 10a is located. The frame body 10a may be made of a conductive material. For example, the frame body 10a may be made of a metal and / or an alloy.

For example, the metal may be Ni, Cu, Al, Ti, Fe, or the like, and the alloy may be a Ni alloy, a Cu alloy, an Al alloy, or an Fe alloy. Specifically, the Ni alloy in the alloy may be a Ni-Cr-based alloy such as a Hi-Nickel or a Ni-Cu-based alloy. The Cu alloy may be the same as the Cu-Ni-Zn-Sn alloy blank Z or the Cu-Be alloy beryllium, which is a brass, bronze, phosphor bronze, Cu-Ni-Zn alloy. Further, the Al alloy may be duralumin, and the Fe alloy may be stainless steel.

A plating layer (20) is placed on the frame body (10a). The plating layer (20) can prevent corrosion of the surface of the frame body (10). The plating layer 20 may be formed of Ni plating, Au plating, Rh plating, Cr plating, or Sn-Ni plating depending on the material of the frame body 10.

The first coating layer 30 is positioned on the plating layer 20. The first coating layer 30 may be made of a material that can be easily bonded to the plating layer 20. [ For example, the first coating layer 30 may be an electrodeposition coating layer or a paint coating layer.

The electrodeposition coating layer may be formed by an electrodeposition coating method. At this time, an acrylic paint or an epoxy paint can be used as the electrodeposition paint. The paint coating layer may be formed by a paint coating method. At this time, an aqueous paint may be used as the paint.

A second coating layer (40) is placed on the first coating layer (30). The second coating layer 40 may be formed on the entire surface of the first coating layer 30 to protect the first coating layer 30. The second coating layer 40 is preferably a hard coating layer having a hardness of 3H (Hard) or less.

The second coating layer 40 may be a transparent layer or a translucent layer. That is, the second coating layer 40 may be a transparent layer to which no pigment is added or a translucent layer to which a small amount of pigment is added.

The second coating layer 40 may contain a coating material and / or a pigment. For example, the paints may be any one selected from lacquer paints, epoxy paints, urethane paints, acryl-urethane synthetic paints, acrylic paints, and ultraviolet curing paints (UV paints).

The coating material may be a first liquid type coating material, a second liquid type coating material or a drying type coating material. When the first liquid type paint is used, a layer can be formed only by the paint and then dried. When the second liquid type paint is used, a three-dimensional molecular structure can be formed by the action of the curing agent by mixing a paint and a curing agent. The drying type paint is similar to the first liquid type paint, but can be dried by volatilizing the solvent in a state dissolved by a solvent.

An adhesive layer (50) is placed on the second coating layer (40). The adhesive layer 50 can improve the adhesion between the second coating layer 40 and a print layer 60 described later. The adhesive layer 50 may be formed of a suitable paint depending on the material of the second coating layer 40 in a lacquer coating, an epoxy coating, a urethane, an acryl-urethane synthetic coating, an acrylic coating, and an ultraviolet curing coating (UV coating) You can choose. The adhesive layer 50 may have a thickness of about 5 占 퐉 to 20 占 퐉.

A printing layer (60) is placed on the adhesive layer (50). The printing layer 60 may be a patterned and / or colored layer. The printing layer 60 may include irregularities 61. That is, the print layer 60 may be a layer printed with embossed patterns and / or colors.

The printing layer 60 may be formed using a UV printer. That is, the print layer 60 may be printed directly on the surface of the adhesive layer 50 through a UV printer. At this time, an ultraviolet curable ink (UV ink) can be used as the ink. The UV ink may be ejected by a nozzle of the UV printer.

Since the UV ink contains almost no solvent and has a very high solid content, there is an advantage that irregularities can be formed in the print layer 60 even by printing once or twice. The irregularities may be formed to a height of 0.2 mm to 1 mm.

A third coating layer 70 is positioned on the printing layer 60. The third coating layer 70 is preferably a hard coating layer having a hardness of 3H (Hard) or less.

For example, the third coating layer 70 may contain any paint selected from an epoxy paint, a urethane paint, an acrylic-urethane synthetic paint, an acrylic paint, and an ultraviolet ray curing paint (UV paint). Further, the paints may be a first liquid type paint, a second liquid type paint or a dry type paint.

The third coating layer 70 not only prevents discoloration of the ink used in the printing layer 60, but also acts as a protective layer against external impact. Therefore, the third coating layer 70 can prevent the print layer 60 from being damaged by physical shock or mechanical deformation at a low temperature of minus 10 ° C or less.

2 is a flowchart showing a method of manufacturing the spectacle frame according to the first embodiment of the present invention.

Referring to FIG. 2, an eyeglass frame body is formed (S100). The frame body may be made of a conductive material. For example, the eyeglass frame body can be formed by cutting a metal or an alloy material and pressing it. Further, it is possible to improve the surface uniformity of the frame body by polishing the formed frame body. At this time, after the polishing, the frame body can be cleaned.

Thereafter, a plating layer is formed on the frame body (S200). For example, the plating layer formation can be achieved by performing rough plating on the surface of an eyeglass frame and performing Ni plating on the roughly plated surface. The primer plating can be performed to prevent the plating layer from being peeled off due to surface uniformity when Ni plating is directly performed on the surface of the polished frame body.

However, the present invention is not limited thereto, and a plating layer can be formed on the frame body by Ni plating, Au plating, Rh plating, Cr plating or Sn-Ni plating alone or in combination thereof depending on the material of the frame body.

A first coating layer is formed on the plating layer (S300). For example, the first coating layer may be formed by filling a tank with a dye or pigment and an electrodeposited paint diluted to a low concentration, and flowing an electric current through the frame body using the frame body as an electrode. The electrodeposition coating may be an acrylic paint or an epoxy paint. At this time, in order to uniformly form the first coating layer, it is preferable that the surface of the plating layer is wiped off before forming the first coating layer so that electricity can be evenly distributed. The first coating layer may be formed on the surface of the layer made of the conductive material, and therefore, the first coating layer may be formed on the entire surface of the plating layer.

A second coating layer is formed on the first coating layer (S400). The second coating layer may contain a coating material and / or a pigment. For example, the coating material may be any one selected from lacquer coatings, epoxy coatings, urethane coatings, acrylic-urethane synthetic coatings, acrylic coatings and UV coatings. The coating material may be a first liquid type coating material, a second liquid type coating material or a drying type coating material. The second coating layer may be formed of a transparent layer or a semi-transparent layer.

The second coating layer may be formed by mixing the selected coating material with a volatile solvent such as a thinner or an organic solvent to form a solution type ink, and spraying the solution type ink onto the first coating layer. At this time, a spray coating may be performed for the spraying. Thereafter, a drying process can be performed. The second coating layer is preferably formed of a hard coating layer having a hardness of 3H (Hard) or less.

An adhesive layer is formed on the second coating layer (S500). The adhesive layer may be formed by selecting a suitable paint according to the material of the second coating layer in a lacquer coating, an epoxy coating, a urethane, an acrylic-urethane synthetic coating, an acrylic coating, and a UV-curing coating, which are drying coatings. The adhesive layer may be formed by mixing the selected paint with a volatile solvent such as a thinner or an organic solvent and spraying the mixed solution onto the second coating layer using a spray coating. Thereafter, a drying process can be performed. The adhesive layer may be formed to have a thickness of about 5 탆 to 20 탆.

A print layer is formed on the adhesive layer (S600). The print layer may be a laminated layer having irregularities on its surface. The irregularities may be formed to a height of 0.2 mm to 1 mm.

The printing layer may be formed using a UV printer. More preferably, a UV flatbed printer can be used. In addition, UV inks may be used in the UV flat panel printer. Since the UV ink hardly contains a solvent, the solid content is very high, so that the printing layer can be printed in a relief form once or twice. The UV ink is preferably a soft ink made of a soft material.

Before printing the print layer, a graphic, a photograph, or a design for forming a pattern and / or a color to be implemented on the print layer may be edited using a computer or the like. At this time, it is possible to remove the hue of the portion to be formed with the engraved, except for the hue of the portion to be embossed.

Thereafter, the frame body is attached to the UV flatbed printer and UV ink is jetted to form the embossed coated printing layer on the adhesive layer. At this time, only the portion to be formed by the embossing is designated to be printed, and the height of the unevenness can be set by adjusting the amount of the UV ink used. In addition, the number of times of printing can be increased in order to increase the height of the unevenness.

A third coating layer is formed on the printing layer (S700). The third coating layer is preferably formed of a hard coating layer having a hardness of 3H (Hard) or less.

For example, the third coating layer may be formed using any one paint selected from an epoxy paint, a urethane paint, an acrylic-urethane synthetic paint, an acrylic paint, and a UV curing paint. The third coating layer may be formed using a spray coating method. Specifically, any one of the paints may be mixed with an organic solvent to form a solution type ink, and the ink may be sprayed onto the print layer to form a third coating layer. Thereafter, a drying process can be performed.

3 is a sectional view showing an eyeglass frame according to a second embodiment of the present invention.

Referring to Fig. 3, the eyeglass frame body 10b is located. The frame body 10b may be made of a flexible material. For example, the spectacle frame body 10b may be made of a synthetic resin material. For example, the synthetic resin may be a polyamide-based, polycarbonate-based, or cellulose synthetic resin. As described above, when the frame body 10b is made of a flexible material, flexibility can be secured.

A first coating layer 30, a second coating layer 40, an adhesive layer 50, and a print layer 60 are successively placed on the frame body 10b. The detailed description of each of the above-described configurations is the same as FIG. 1, and therefore will not be described. Since the frame body 10b is made of a synthetic resin material, the plating layer 20 disclosed in Fig. 1 is not required.

The semi-cured coating layer 80 may be positioned on the printing layer 60. The semi-cured coating layer 80 has a hardness of 3H (Hard) or less, more preferably a hardness of 1 H (Hard) or less. The semi-cured coating layer 80 is preferably maintained in a semi-cured state.

For example, the semi-cured coating layer 80 may contain any paint selected from epoxy paints, urethane paints, acrylic-urethane synthetic paints, acrylic paints, and UV paints. In addition, the paints may be a second liquid type paint.

The semi-cured coating layer 80 can absorb the stress caused by the difference in thermal expansion coefficient between the printing layer 60 and the third coating layer 70 and can improve the adhesion of the protrusions 60 and 70. In addition, the semi-cured coating layer 80 protects the print layer 60 by blocking fine foreign substances or the like that can penetrate through the third coating layer 70, and absorbs a physical impact applied from the outside .

A third coating layer 70 is positioned on the semi-cured coating layer 80. The third coating layer 70 is preferably a soft coating layer having hardness less than HB (hard black). The third coating layer 70 may be formed on the semi-cured coating layer 80 in a semi-cured state of the semi-cured coating layer 80.

For example, the third coating layer 70 may contain any paint selected from an epoxy paint, a urethane paint, an acrylic-urethane synthetic paint, an acrylic paint, and a UV paint. Further, the paints may be a first liquid type paint, a second liquid type paint or a dry type paint.

The third coating layer 70 not only prevents discoloration of the ink used in the printing layer 60 but also acts as a protective layer against external impact. Therefore, the third coating layer 70 can prevent the print layer 60 from being damaged even under physical impact or mechanical deformation at a low temperature of minus 10 ° C or less.

Thereafter, the first coating layer, the second coating layer, the adhesive layer, and the printing layer are sequentially formed on the spectacle frame body (S200 to S500). The detailed description of each of the steps is the same as that of FIG. 2, and thus will be omitted.

A semi-cured coating layer is formed on the printing layer (S600). The semi-cured coating layer may be formed of a hard coating layer having a hardness of 3H (Hard) or less, more preferably a coating layer having a hardness of 1H (Hard) or less.

For example, the semi-cured coating layer may be formed using any one paint selected from an epoxy paint, a urethane paint, an acrylic-urethane synthetic paint, an acrylic paint, and a UV paint.

The semi-cured coating layer may be formed using a spray coating method. Specifically, any one of the paints may be mixed with an organic solvent to form a solution-type ink, and the ink may be sprayed onto the print layer. Thereafter, the curing can proceed until the injected ink becomes semi-cured. Therefore, the semi-cured coating layer can maintain a semi-cured state.

A third coating layer is formed on the semi-cured coating layer (S700). The third coating layer is preferably formed of a soft coating layer having hardness less than HB (Hard). The third coating layer may be formed on the semi-cured coating layer in a semi-cured state of the semi-cured coating layer.
