Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for manufacturing spectacle members which are constituent members of spectacles such as temples, rim frames, moderns, and pads.
[0002]
[Prior art]
Conventionally, eyeglass members have been manufactured by processing metal or have been manufactured by molding using resin.However, processing using resin can be easily processed into a complicated shape, Since it is possible to give a color and attach a decorative member, it is generally widely used. However, when a color is applied, since a resin can be colored only in a single color, it has been difficult to give a multicolored pattern to the resin itself to have a more decorative effect. Printing and transferring with a color material on the surface is also performed, but there is a possibility that the color does not have a depth, and the color is peeled off while wearing the glasses and deteriorates.
[0003]
Therefore, a method of giving a pattern of a plurality of colors to the resin itself has been proposed. For example, in Japanese Patent Application Laid-Open No. H10-142559, an uneven portion is formed in a main body of an eyeglass member, the main body is housed in a closed mold, and has a melting temperature lower than a heat resistant temperature of a resin constituting the main body. A method of manufacturing a spectacle member for injecting a resin into a mold in a molten state and integrally molding the resin with a main body is described. In addition, Japanese Utility Model Registration No. 3059644 describes a method for manufacturing an eyeglass member by joining and integrating at least two types of synthetic resin pieces having different colors or textures. Further, Japanese Patent No. 3015789 discloses a method for manufacturing a spectacle member in which a plurality of resin block pieces are fitted, a joint portion thereof is dissolved with a solvent, and the melted portion is integrated.
[0004]
[Problems to be solved by the invention]
In such a conventional technique, for example, in the manufacturing method described in Japanese Patent Application Laid-Open No. H10-142559, it is difficult to manufacture other than a combination of resins having different melting temperatures. Equipment is needed. In the manufacturing method described in Japanese Utility Model Registration No. 3059644, it is necessary to process the synthetic resin piece into a complicated shape having a fitting part in which the shape of the synthetic resin piece is complicated. Therefore, it is necessary to obtain the final shape, and thus a more complicated external shape is processed. In the manufacturing method described in Japanese Patent No. 3015789, a joining tool between resin blocks is melted and joined with a solvent, so that a processing tool such as a mold for fixing the resin block is required. Because of joining, it is difficult to express a sharp pattern with blurred boundaries of the resin blocks.
[0005]
SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks of the prior art and to provide a method for manufacturing a spectacle member capable of displaying a pattern of a plurality of colors in a simple manufacturing process.
[0006]
[Means for Solving the Problems]
In the method for manufacturing an eyeglass member according to the present invention, a hole having a bottom is formed in a predetermined shape in a base block made of a resin, and a fitting block made of a resin is formed into a shape substantially matching the predetermined shape, A liquid adhesive is applied to the formation surface of the hole of the base block, the fitting block is fitted into the hole, and then the base block is heated, and the base block and the fitting block integrated with the adhesive are machined. Molding. The fitting block has a built-in metal core.
[0007]
Since the present invention has the above-described configuration, the positioning can be easily performed by forming a hole having a bottom in the base block and fitting the fitting block therein, so that a processing tool such as a mold is used. It becomes unnecessary, and since both are integrated, the final shape of the spectacle member is machined to form, so that the base block and the fitting block can have any shape other than the joint surface, and the manufacturing process can be simplified. .
[0008]
In addition, since the liquid adhesive is applied to the formation surface of the bottomed hole portion and the fitting block is fitted, the adhesive spreads evenly over the entire joining surface of the base block and the fitting block and is heated after being fitted. By doing so, the air remaining on the joint surface can be released and the joint surface can be securely bonded. Fitting the fitting block into the hole with the bottom is particularly effective because air tends to remain.
[0009]
In addition, since the base block and the fitting block are processed into a predetermined shape in advance, various patterns can be displayed if different colors are arranged respectively. In particular, by coloring one of them translucently, the other color also appears inside the eyeglass member, so that a deep decorative effect can be expected.
[0010]
Also, if you make the adhesive layer thinner or make the color of the adhesive the same color as one block, the boundaries of the color scheme will be clearer, and you can express a sharp and deep pattern, so more The decoration effect can be further enhanced.
[0011]
If a metal core is preliminarily incorporated in the fitting block, a spectacle member with increased strength can be manufactured.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments according to the present invention will be described in detail. FIG. 1 shows the entire manufacturing process. The base block 3 is formed by cutting a plate-like body 1 made of a synthetic resin such as acetate or celluloid into a rectangular shape having a predetermined size, and cutting the upper surface thereof with a cutter or the like to form a hole 5 having a predetermined shape.
[0013]
FIG. 2 shows a plan view and a side view of the base block 3 in which the holes 5 having a predetermined shape are formed. The depth of the hole 5 is cut so that the bottom 3 a is formed shallower than the thickness of the base block 3. In this case, the base block 3 is formed from a single rectangular body. For example, as shown in FIG. 4, a rectangular body 31 in which a through hole is formed in a predetermined shape with a cutter or the like in advance has the same outer shape as the rectangular body 31. If the rectangular body 32 is integrated with an adhesive or the like, the same thing as the base block 3 described above can be formed. On the other hand, the fitting block 4 is formed by cutting a plate-like body 2 made of a synthetic resin such as acetate or celluloid with a cutter or the like into a shape substantially matching the hole 5. The fitting block 4 is colored differently from the base block 3. FIG. 3 shows a plan view and a side view of the fitting block 4 formed into a predetermined shape. It is preferable that the thickness of the fitting block 4 is formed so as to substantially match the depth of the hole 5.
[0014]
After the hole 5 is formed in the base block 3, a liquid adhesive 6 is applied to the cut surface of the hole 5 by a coating device 7. Thereafter, the fitting block 4 is fitted into the hole 5. The adhesive 6 is desirably applied to the entire cutting surface. However, a predetermined amount of the adhesive 6 is applied to the bottom 3a, and when the fitting block 4 is fitted, the adhesive 6 is pressed against the entire joining surface. You may be able to go around. Next, the heating device 8 heats the lower surface of the fitting block 4 with the fitting block 4 fitted thereto. By heating the entire base block 3, the air remaining on the joint surface expands, rises in the adhesive 6, and is discharged to the outside. The heating temperature is preferably between 90C and 95C. If heated at too high a temperature, the base block 3 itself may be deformed. At low temperatures, the air does not rise well and the adhesive solidifies, leaving air bubbles. It is important to cool immediately after heating to prevent the generation of bubbles.
[0015]
Air is released by heating, and the adhesive 6 is sufficiently spread and solidified on the joining surface, so that the base block 3 and the fitting block 4 are completely integrated. Then, by performing machining such as cutting and grinding, it is finished to the final shape of the temple which is an eyeglass member. After that, finishing processing such as surface processing is performed. In the spectacle member, resins of different colors are exposed as a pattern along the joint surface, and a sharp and deep decorative effect is achieved. Further, if the bottomed portion of the base block 3 is processed to be left in a thin film shape, the joining surface is not exposed, so that the durability is improved and the color of the mating block 4 can be seen through. It is also possible to put out.
[0016]
FIG. 5 shows a case where the fitting block incorporates a metal core material. When manufacturing the plate-like body 2, a plurality of metal cores 12 are arranged at predetermined intervals in advance, and after being solidified with a resin so as to cover the cores 12, a cutter is provided so as to surround each core 12. If the cutting is performed by the above method, the fitting block 11 in which the core material 12 is built can be formed. When the mounting portion 13 is formed on the core material 12, the resin may be solidified in a state where the mounting portion 13 is exposed. Then, the eyeglass member is fitted to the base block 10 with the mounting portion 13 facing upward, and thereafter, the same manufacturing method as described above is performed, whereby an eyeglass member with increased strength can be manufactured.
[0017]
【The invention's effect】
As described above, the method for manufacturing the spectacle member according to the present invention can easily position by forming the bottom hole in the base block and fitting the fitting block in the hole, so that the mold and the like can be used. No processing tool is required. That is, since a plurality of block pieces are conventionally joined so as to combine puzzles, misalignment is likely to occur, but in the present invention, misalignment can be completely prevented by fitting. In addition, since the two are integrated and then machined into the final shape of the spectacle member, the base block and the fitting block may have any shape other than the joint surface. Since the shape of the joint surface ultimately determines the pattern of the eyeglass member, precise processing is required, but other shapes can be any shape because they are finally formed by machining, and workability What is necessary is just to make it a good shape. As described above, according to the manufacturing method of the present invention, the manufacturing steps can be simplified.
[0018]
In addition, since the liquid adhesive is applied to the formation surface of the bottomed hole and the fitting block is fitted, the adhesive can be spread evenly over the entire joining surface of the base block and the fitting block. Since the hole has a bottom, if a predetermined amount of liquid adhesive is applied to the bottom of the hole, the surplus adhesive overflows to the outside after the fitting block has been fitted and has spread over the entire joint surface. Therefore, the adhesive can be surely spread over the entire joint surface. Then, by heating the fitting block after fitting, the air remaining on the bonding surface is released, and the bonding surface can be securely bonded. Fitting the fitting block into the hole with the bottom is particularly effective because air tends to remain.
[0019]
In addition, since the base block and the fitting block are processed into a predetermined shape in advance, various patterns can be displayed if different colors are arranged respectively. In particular, by coloring one of them translucently, the other color is exposed to the inside of the eyeglass member, so that a deep decorative effect can be expected. Also, if you make the adhesive layer thinner or make the color of the adhesive the same color as one block, the boundaries of the color scheme will be clearer, and you can express a sharp and deep pattern, so more The decoration effect can be further enhanced.
