Description

Composite wooden glasses manufacturing method

The present invention relates to a manufacturing method of customized glasses, especially a manufacturing method of composite wooden glasses which introduces an innovative manufacturing process and can maintain a highly mobile production mode and price advantage.

By the way, most of the spectacle frame materials on the market are mainly metal and plastic materials. Although plastic spectacle frames have the advantages of lightness, easy processing, easy coloring, and high hardness, they are also hard because of their brittle texture and ductility. Not too high, which makes it not so comfortable to wear, the weight of the sheet material is relatively heavy, and the strength is not enough. In addition, if the size is wrong, it will easily deform after wearing for a long time, and if the subsequent recycling work is not handled properly, it will cause environmental pollution and other problems. . Compared with the metal frame, although it is not as harmful to the environment as the plastic frame, and its material is also light and easy to process, and it is stronger than the plastic frame, but its disadvantage is that the weight of the metal material is lighter than that of the plastic frame. The plastic material is much heavier, and because the environment is humid and hot, sweat easily corrodes the frame. After direct contact with the skin, the nickel-containing metals that are poorly plated and leak out will cause skin allergies, redness, swelling, and even ulceration. .

Furthermore, due to the importance of glasses to the eyes, in addition to wearing comfort, it is also necessary to consider the correlation between human factors and the human body. Everyone's head shape and face size, including the size of the nose, eyes and ears, are not the same, and even the shape of the individual face is not symmetrical. and glasses as One of the products that are closest to the human body, if the importance of human factors is ignored, it will lead to incorrect wearing, which will not only affect the comfort, but may even cause eye damage. Therefore, customized glasses are designed to meet more glasses users with different needs , Its development has become one of the popular trends in the modern glasses industry.

In addition, since there are frames on the market that develop customized technology, they are made of plastic and wood. In terms of plastic mirror frames, most of the manufacturing processes are injection molding or mold opening molding. The plastic mirror frames that truly realize the customization technology use 3D printing technology to obtain the customer's face size through computer software to define the size of the mirror frame, and then use 3D printing technology's unique Fused Deposition Modeling (Fused Deposition Modeling, FDM) is used for production, although it can save time and cost and quickly design and manufacture, but because of its fused lamination technology and the characteristics of the material itself are relatively fragile, The structure of the plastic mirror frame is relatively insufficient, and there are even cases where it cannot be restored after being broken, that is, the structural support is insufficient and the wear rate is high. In addition, its material and manufacturing technology are applied to the research and development of customized glasses. The surface color and texture are relatively ordinary, and the degree of recognition is not high, so it is difficult to highlight the value of customized frames. As for wooden mirror frames, most of them are made of solid wood on the market. Although the material itself is natural and harmless, it has a very high affinity for the skin. In addition to the very recognizable appearance design, it seems to be very suitable for the market demand for customized mirror frames. , but its solid texture makes its weight quite heavy, which has caused a great burden on the user's comfortable experience of wearing a solid wood frame, and because solid wood has a solid but crisp texture, it is easy to break or break during the production process. Damage greatly affects the difficulty of its material processing and production. Therefore, most of the solid wood frames are custom-made by hand, which is not only time-consuming, but also relatively low in output. , has a very high price.

Therefore, how to develop a pair of innovative and customized wooden glasses, in addition to considering the weight of the frame, the color of the material, and whether the user's wearing comfort meets the needs of the customization industry In addition, at the same time, it can also ensure that the production method achieves a highly flexible processing process, so that it can be processed according to different needs, so as to solve the above-mentioned problems of high cost and low sales volume of customized eyewear products, which not only has its necessity and market The demand of the industry is also the goal of the research and development efforts of the relevant industry.

b, sheet material preparation: (as shown in the 3rd figure), be based on the size of the 3D virtual model 41 of above-mentioned mirror frame 20 and hanging ear 30, respectively make appropriate pressing molding mold 50, and this mold when making, The selection of its material can use the plywood with high stability and strong structure as the material to make the male and female molds (51, 52), and on the pressing surfaces of the male and female molds (51, 52), there are respectively formed with The shape of the spectacle frame has the same radian and can be parallel and tightly fitted curved surface, and positioning pins 53 and positioning holes 54 are respectively provided at the corners to make the male and female molds (51, 52) For a stable and tight fit.

And this composite plate 60 is applied the cross-lamination (CLT) technology, cut the long and short-fiber wood veneers (61, 62) of appropriate size into the carbon fiber composite material 63, and vertically cross-stacked and glued, and then through the above-mentioned forming The mold 50 is press-molded to prepare the composite plate 60 with the curvature of the glasses frame. In addition, the above-mentioned long and short fiber wood veneers (61, 62) can be prepared in the material preparation stage, and then a complete wood veneer 60a can be leveled by weight pressure, and then divided and arranged according to the fiber direction, and then cut by laser Cutting the leveled wood veneer 60a can not only improve the output quality of the long and short fiber wood veneer (61, 62), but also improve its production efficiency. Furthermore, in this preferred embodiment, since the thickness of the laminated board required for the overall shape design of the glasses is about 10 mm, the wooden laminated composite board 60 can be glued together by a total of 19 layers of cross-stacking (about 10 mm) , and considering that the long-fiber wood flakes 61 have a greater structural support than the short-fiber wood flakes 62, the long-fiber wood flakes 61 are designed to be placed on the surface of the spectacle frame (that is, the position of the odd number layer), while the short-fiber wood flakes 62 And the carbon fiber composite material 63 is then embedded in the even number of layers. In addition, because the carbon fiber composite material 63 has good support and toughness, when the composite plate 60 is implemented, the carbon fiber composite material 63 can be designed to be placed on the front three layers equivalent to the surface of the frame, that is, arranged in the The second, fourth and sixth layers are used to increase the protective surface and structural support, so that the finished product can obtain higher quality and better elasticity. In addition, the glue used for the gluing of each layer of boards can be a special waterproof glue for wood, and it is uniformly rolled by a silicon rubber roller 70 in a quantitative manner (about 1 cc for the wooden layer and about 1.5 cc for the composite layer).
