Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of manufacturing a carbon frame having flexibility and bending,

The present invention relates to a method of manufacturing a carbon frame including a front or a leg using a carbon material. More specifically, the present invention relates to a method of manufacturing a front frame or a leg including a front or rear leg having a predetermined curvature, To a method of manufacturing a carbon frame having self-flexibility and bending such that a leg can be fabricated and a product is lightweight and excellent in rigidity and durability.

Normally, eyeglasses complement the eyesight of a wearer, but in recent years, it has been used mainly as a fashion accessory that protects the eyes and shows the personality of the wearer. These glasses have a very limited range of design changes, so it is difficult to apply a new design other than the deformation of the pattern, and therefore a new design is always pursued. Particularly, in the case of eyeglasses legs, it has been common to design through shapes and colors. However, in recent trends of demanding diversification of designs, a core (reinforcing material) made of steel or the like is provided inside the eyeglass legs, One or more multi-colors are formed to change the design.

On the other hand, the carbon material which is partially applied to the glasses is light and has excellent elasticity. Although the surface treatment such as dyeing and plating is convenient, the carbon sheet can not be formed by injection molding. In particular, In particular, when a pair of eyeglasses legs are manufactured, it is possible to obtain an eyeglass leg having an excellent appearance, but because of the excellent elasticity of the carbon material, plastic processing can not be performed. That is, the carbon sheet cured in the state where the carbon cloth is laminated has a flat plate structure, and it is very difficult to utilize the carbon sheet for an eyeglass frame made of a predetermined curvature such as a front. Therefore, it has been recognized that it is impossible to attach a carbon sheet having excellent strength or aesthetics to a spectacle frame in recent years, but recently, a carbon seat is used only in a spectacle frame without a curvature.

As prior art documents which can be referred to in this connection, Korean Patent Laid-Open No. 10-2013-0130363 (Prior Art 1) and Korean Patent Registration No. 10-1410247 (Prior Art 2) are known.

In the prior art document 1, a metal core is inserted into a carbon sheet having an intrinsic lattice pattern, and the earring portion of the eyeglass leg is coated with a soft covering material such as silicone and rubber to form a curvature of the earring portion of the eyeglass leg . Thus, since the spectacle leg is manufactured using the carbon sheet having various colors by dyeing and plating the carbon sheet, the inherent lattice pattern of the carbon sheet is exposed on the surface of the legs of the eyeglass to provide glasses having an excellent appearance It is easy to form the earring part by bending the core material of metal material and it is possible to easily form the curvature of the eyeglass legs, and it is possible to form the design of the eyeglass legs variously, I expect the effect to be.

The prior art document 2 does not cause physical damage to the carbon frame itself made of carbon material, but it prevents the exposure of the fixed part of the hinge while making stable connection between the front and the leg made of carbon material, A structure for providing a hinge mounting structure of a carbon eyeglass frame in which hinges of various shapes and specifications can be commonly installed through a single molding die and a manufacturing method of a carbon frame frame having an improved connection structure, I suggest. Thus, in manufacturing a carbon frame having light weight and excellent strength, it is expected that the hinge can be easily and stably installed on a front or a leg made of a carbon material.

However, although the above-mentioned prior art provides a method of manufacturing an eyeglass frame, that is, a front or a leg using a carbon material, since most of the carbon material is not only made of a carbon material but also a composite material such as glass fiber is used It is difficult to secure flexibility due to the nature of the material itself, which is disadvantageous in that the feeling of fit is inconvenient.

The present invention relates to a method of manufacturing an eyeglass frame including a front or a leg using a carbon material. In the manufacture of a frame made of a carbon material, only a carbon material is used in manufacturing, so that it is light and has a good appearance, Which is excellent in rigidity and durability as well as being lightweight in its products, and which has its own flexibility and bending property.

The method of manufacturing a carbon frame according to the present invention is to form a front F or a leg L constituting an eyeglass frame so as to have its own flexibility and curvature as shown in FIG. 6, wherein the front F or the leg L The manufacturing method is the same, and only legs L are shown in the drawing.

The preparing step (S10) of the present invention uses a carbon material to weave into a sheet to produce a carbon sheet (10). In this preparing step S10, the carbon sheet 10 is woven using a carbon material as shown in FIG. 2. The carbon sheet 10 is woven in plain weave, twill weave, or twill weave, and then cut to a proper size to prepare the carbon sheet 10.

In the laminating step (S20) of the present invention, the carbon sheet (10) and the core (20) in the preparing step (S10) are arranged and laminated. In this laminating step S20, the carbon sheet 10 and the core 20 are arranged with respect to each other as shown in Fig. 3, in which the core 20 is arranged on the carbon sheet 10, The carbon sheet 10 is laminated.

In the laminating step S20 of the present invention, the core 20 is inserted into the carbon sheet 10 in a state where the patterns of the carbon sheet 10 are crossed with each other in an oblique direction, and the carbon sheet 10 is fixed with the applied adhesive resin liquid 25 . As shown in Fig. 3, the carbon sheet 10 is arranged so that the woven patterns are arranged diagonally, and then the carbon sheets 10 are crossed with each other. Next, the core members 20 are arranged in a lined arrangement and the carbon sheet 10 is laid on the top of the core member 20 in a diagonal direction. Here, the carbon sheet 10 is impregnated with the adhesive resin solution so as to be applied thereon, so as to be laminated between the carbon sheets 10.

The laminating step S20 of the present invention is a step of laminating the filling tip 15 cut with the carbon sheet 10 in order to eliminate a step on the step surface 21 formed between the core material 20 and the core material 20, (S25) for attaching the first and second electrodes to each other. This attaching step S25 is further executed after the laminating step S20. This attaching step S25 occurs in the step of arranging the core pieces 20 in the carbon sheet 10 in the laminating step S20 as shown in Fig. 4 . That is, a stepped surface 21 which is recessed between the core 20 and the core 20 is generated, an attaching step S25 is provided to prevent this. This attaching step S25 is a step of attaching the filling tip 15 cut from the carbon sheet 10 laminated in such a manner that the patterns are arranged in an oblique direction so as to intersect with each other to form a recessed stepped surface between the core 20 and the core 20. [ 21 to prevent the step from occurring.

In the laminating step S20 of the present invention, the laminating step S20 includes a patterning step of applying a curved layer 17 cut with a carbon sheet 10 to impart surface bending to both ends of the core material 20 S27). &Lt; / RTI > The pattern step S27 is further executed after the stacking step S20. The carbon sheet 10 laminated so that the patterns are arranged in the diagonal direction and intersected with each other is cut in the same manner as in the attachment step S25 as shown in Figs. 4 and 5 to form a curvature on the front surface F or the legs L (S25). &Lt; / RTI > In this pattern step S27, the carbon sheet 10 cut at both ends of the core 20 is laminated stepwise to form a curved layer 17 so as to have a curved shape, The front F or the leg L can be manufactured.

In the forming step S30 of the present invention, the carbon sheet 10 and the core 20 of the laminating step S20 are cured through an autoclave to form an integral front F or leg L. The forming step S30 is performed by the front face F or the leg L of the lumbering product which has undergone the laminating step S20, the attaching step S25 and the pattern step S27, that is, the laminating step S20. The core member 20 is inserted in a state in which the core member 20 and the core member 20 are stacked so as to cross each other in an oblique direction and then the carbon sheet 20 is inserted into the recessed surface 21 between the core member 20 and the core member 20 through the attaching step S25. The carbon sheet 10 cut at both ends of the core material 20 is laminated step by step through the pattern step S27 and the curved surface layer 17 is provided, Is cured by vacuum autoclave molding to form an integral front (F) or leg (L). This vacuum autoclave molding is performed by sealing a vacuum cavity with a sealing tape to form a cavity above the molding and then curing the cavity by heating it with a vacuum pump through one side passage of the vacuum bag while heating the cavity. That is, since heat is supplied while keeping the vacuum state while maintaining the equivalent pressure outside the vacuum space, the volatile matter generated from the adhesive resin solution is removed, and the bonding between the respective layers of the laminated carbon sheet 10 and the core material 20 Can be fully implemented.

The completion step S40 of the present invention is completed by finishing the formed front F or leg L of the molding step S30.
