Description

Technical Field

[0001] This invention relates to the field of eyeglass temple technology, and in particular to an eyeglass temple material combining carbon fiber and ABS and its manufacturing method. Background Technology

[0002] Consumers' ever-increasing latent demand for eyewear has spurred the continuous development of various new materials for eyeglass temples, with carbon fiber emerging as a unique development direction. Traditional eyeglass temple materials can be mainly divided into metal, plastic, and composite materials. Metal temples are sturdy and durable, but can easily cause skin allergies and discomfort; plastic temples are inexpensive and offer a wide variety of styles, but their structural durability is poor and product quality varies; composite temples are stable, reliable, and weather-resistant, but their manufacturing process is complex and difficult. However, using carbon fiber to process eyeglass temples combines the advantages of all the above materials while avoiding the aforementioned problems.

[0003] As described in the invention patent authorization announcement number CN106970473B, a carbon fiber eyeglass temple and its preparation process are described. This invention mainly uses carbon fiber as raw material to prepare eyeglass temples, which have excellent properties such as light weight, high structural strength, high environmental stability, and good tolerance. In addition, it has good wear resistance, fatigue bending resistance, long service life, and wide applicability. The carbon fiber cloth is woven by weaving, so that the carbon fiber raw material filaments with different principal axis directions are orthogonally hybridized in a two-dimensional plane with continuously changing angles and directions, so that the mechanical strength and modulus coverage of the raw material cloth are comprehensive.

[0004] However, eyeglass temples made primarily of carbon fiber are difficult to drill, and after drilling, they require grinding and polishing. The area at the temple tip where the eyeglass frame is assembled is also difficult to process, which increases production costs. Therefore, it is necessary to propose a new technical solution to address these issues. Summary of the Invention

[0005] To overcome the shortcomings mentioned above, the present invention aims to provide a technical solution that can solve the above problems.

[0006] A type of eyeglass temple material combining carbon fiber and ABS includes an eyeglass temple body. The eyeglass temple body has a front head, a middle transition part, and a rear ear part. The eyeglass temple body includes two carbon fiber composite layers and an ABS filling layer sandwiched between the two carbon fiber composite layers. The ABS filling layer is located at the head of the eyeglass temple body, making the head of the eyeglass temple body thicker. An assembly hole is provided at the front of the eyeglass frame body corresponding to the position of the ABS filling layer.

[0007] Preferably, the carbon fiber composite layer has a first carbon fiber braided layer and a second carbon fiber braided layer. An electronic cloth is attached to the second carbon fiber braided layer at the head position of the main body of the eyeglass temple. The two carbon fiber composite layers are attached together through the second carbon fiber braided layer, and the head of the main body of the eyeglass temple is separated by the electronic cloth to fill the ABS filling layer.

[0008] Preferably, the ABS filler layer includes a front square portion and a rear recessed portion, with the assembly hole opened on the square portion, and the heads of the two carbon fiber composite layers opening through the recessed portion for transition.

[0009] Preferably, the first carbon fiber woven layer is made of carbon fiber woven fabric, and the second carbon fiber woven layer is made of angled yarn.

[0010] Preferably, a paint layer is wrapped around the side of the first carbon fiber braided layer that faces away from the second carbon fiber braided layer.

[0011] Preferably, a frosted layer is provided on the side of the first carbon fiber braided layer facing away from the second carbon fiber braided layer. A base oil layer is sprayed onto the first carbon fiber braided layer through the frosted layer, and a gold oil layer is sprayed onto the base oil layer. The paint layer is sprayed on the outside of the gold oil layer.

[0012] Preferably, a prepreg layer is provided between the first carbon fiber braided layer and the second carbon fiber braided layer, and the first carbon fiber braided layer and the second carbon fiber braided layer are bonded to each other through the prepreg layer.

[0013] A method for manufacturing a temple plate made of carbon fiber and ABS, comprising the aforementioned temple plate made of carbon fiber and ABS, including the following steps:

[0014] Step 1: Material preparation. Take out the required prepreg from the freezer. The prepreg includes carbon fiber woven fabric and angle yarn. The storage temperature is 23℃±2℃. Cut the yarn according to the preset size, warp direction and structure sheet of the prepreg. Cut the prepreg into the required size and angle according to the structure sheet. Prepare the corresponding ABS filler layer according to the prepreg.

[0015] Step 2: Laying the material. Overlap and laminate the carbon fiber woven fabric and the angle yarn, and sandwich an ABS filler layer in front of the two layers of carbon fiber woven fabric. When laminating the prepreg, smooth it out to ensure there are no air bubbles or wrinkles, and there should be no foreign matter in the prepreg. After laminating, attach a layer of electronic cloth to the head position of the angle yarn side of the prepreg laminate. After attaching, laminate the angle yarn side of the two materials together to form the prepreg laminate.

[0016] Step 3: Molding; According to the size of the prepreg, set up a hot press mold. After blowing away the impurities on the surface of the bonded prepreg layer with air, place it into the mold and place it correctly in the lower mold for about 30 seconds for preheating. After ensuring the precise placement of the prepreg bonded layer, close the mold. After closing the mold, set the molding conditions: temperature control at 135℃±5℃, molding time control at 40min±2min. After molding, cool to 18℃±5℃ before opening the mold. After cooling and curing, the initial eyeglass temple sheet is produced.

[0017] Step 4: Apply oil. Grind the surface of the initial eyeglass temple plate with 320-grit sandpaper, clean the surface of the ground initial eyeglass temple plate, and apply a layer of base oil. After applying the base oil, apply multiple layers of gold oil. After each layer of gold oil is applied, bake it in the oven to cure before applying more oil. Bake the sprayed product in an electric oven for 4 hours, with the baking temperature controlled at 75℃±5℃.

[0018] Step 5: Painting. After the product baked in Step 5 has cooled, use 600-grit sandpaper to grind the surface sand particles. Use a 100-grit belt sander to smooth the product edges. After sanding, clean the surface first, and then spray paint evenly on the surface to make the initial finished product of the eyeglass temple plate.

[0019] Step 6: Sanding and cleaning. After the initial product of the eyeglass temple material is made, inspect the appearance for any rough defects or paint blistering. Sand the material in sequence with 320-grit, 400-grit, and 600-grit sandpaper according to the thickness. The surface should be sanded evenly and smoothly without any unevenness. Finally, immerse the sanded product in a plastic frame containing detergent for a certain period of time, with the water temperature controlled at 80℃. After cleaning, the finished eyeglass temple material is produced.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] Using ABS as the filling material, the main body of the temple is made of two layers of carbon fiber composite layers bonded together. By leaving the two carbon fiber composite layers unbonded at their ends, the ends of the two carbon fiber composite layers can be opened to form an opening structure. By placing a filling material in this opening structure, that is, sandwiching an ABS filling layer between the ends of the two carbon fiber composite layers, and by making assembly holes in the filling layer, it is easy to process the position of the temple end for mounting the eyeglass frame, thereby reducing production and processing costs.

[0022] By using an ABS filler layer, the curvature design of the temples can be achieved simultaneously through the filling of ABS resin. This allows the temples to fully utilize the material's properties while meeting aesthetic requirements. As a result, compared to temples of similar shapes, the overall performance of the composite material is improved and its lifespan is increased.

[0023] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-3In this embodiment of the invention, a temple plate combining carbon fiber and ABS is mainly characterized by an embedded filling material on the temple body 10 at the head position connecting to the eyeglass frame. This filling material is designed to facilitate drilling and has a certain degree of plasticity to maintain its shape, thus facilitating drilling operations. Specifically, the temple body 10 has a front head, a middle transition portion, and a rear ear portion. The temple body 10 includes two carbon fiber composite layers 20 and an ABS filling layer 30 sandwiched between the two carbon fiber composite layers 20. The ABS filling layer 30 is located at the head position of the temple body 10, making the head position of the temple body 10 thicker. An assembly hole 31 is provided at the front end of the eyeglass frame body corresponding to the position of the ABS filling layer 30.

[0033] ABS resin is one of the five major synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It is also easy to process, has stable product dimensions and good surface gloss. It is easy to paint and color. Using ABS as the filler material, the main body 10 of the temple is made of two carbon fiber composite layers 20 bonded together. By leaving the two carbon fiber composite layers 20 unbonded at the head position, the head of the two carbon fiber composite layers 20 can be opened to form an opening structure. By setting the filler material in this opening structure, that is, by sandwiching an ABS filler layer 30 between the head of the two carbon fiber composite layers 20, and by making an assembly hole 31 in the filler layer, it is easy to process the position of the temple head for mounting the eyeglass frame, thereby reducing the production and processing cost.

[0034] Furthermore, by using ABS filler layer 30, the curvature design of the temple lines can be simultaneously achieved through the filling of ABS resin, allowing the temples to fully utilize the material properties while meeting aesthetic requirements. As a result, compared to temples of similar shapes, the overall performance of the composite material is improved and its lifespan is increased.

[0035] Please see Figure 1-3The carbon fiber composite layer 20 has a first carbon fiber woven layer 21 and a second carbon fiber woven layer 22. The first carbon fiber woven layer 21 is made of carbon fiber woven fabric, and the second carbon fiber woven layer 22 is made of angled yarn. Using carbon fiber materials of different specifications can improve the overall performance, thereby achieving requirements such as high strength, corrosion resistance, impact resistance, wear resistance, colorfastness, light weight, good elasticity, non-deformation, and rust resistance. Based on the opening structure, an electronic cloth 23 is attached to the second carbon fiber woven layer 22 at the head position corresponding to the temple body 10. The two carbon fiber composite layers 20 are attached through the second carbon fiber woven layer 22, and the head of the temple body 10 is separated by the electronic cloth 23 to fill the ABS filling layer 30. The electronic cloth 23 ensures that the head positions of the two carbon fiber composite layers 20 are not stuck together when they are attached, thus forming an opening structure after attachment to fill the ABS filling layer 30. This structure simplifies the process and improves production efficiency.

[0036] Please see Figure 1 and Figure 3 Based on the embedded setting of the ABS filling layer 30, the main body 10 of the eyeglass temple has an expanded outward convex structure at the head position. In order to achieve an aesthetically pleasing curvature setting, the ABS filling layer 30 includes a square part 32 at the front and an inward part 33 at the rear. The mounting hole 31 is opened on the square part 32, and the head opening of the two carbon fiber composite layers 20 is transitioned through the inward part 33.

[0037] Please see Figure 2 The exterior of the carbon fiber composite layer 20 needs to be painted to provide protection and improve performance. The tight bond between the paint layer 11 and the carbon fiber composite layer 20 requires a certain transition to prevent direct contact between the paint layer 11 and the carbon fiber composite layer 20, which could lead to weak adhesion or wear and affect the overall high transparency of the inner layer. Therefore, the paint layer 11 is wrapped around the side of the first carbon fiber braided layer 21 facing away from the second carbon fiber braided layer 22. A frosted layer 12 is provided on the side of the first carbon fiber braided layer 21 facing away from the second carbon fiber braided layer 22. The first carbon fiber braided layer 21 is sprayed with a base coat 13 through the frosted layer 12, and a gold coat 14 is sprayed on the base coat 13. The paint layer 11 is sprayed on the outside of the gold coat 14.

[0038] Please see Figure 2 A prepreg layer 24 is provided between the first carbon fiber braided layer 21 and the second carbon fiber braided layer 22, and the first carbon fiber braided layer 21 and the second carbon fiber braided layer 22 are bonded to each other through the prepreg layer 24.

[0039] Please see Figure 1-4Based on the above structural design, this embodiment will further elaborate on its manufacturing method. Specifically, a method for manufacturing a temple plate combining carbon fiber and ABS is provided, including the aforementioned temple plate combining carbon fiber and ABS, comprising the following steps:

[0040] Step 1: Material preparation. Take out the required prepreg from the freezer. The prepreg includes carbon fiber woven fabric and angle yarn. The storage temperature is 23℃±2℃. Cut the yarn according to the preset size, warp direction and structure sheet of the prepreg. Cut the prepreg into the required size and angle according to the structure sheet. Prepare the corresponding ABS filler layer 30 according to the prepreg.

[0041] Step 2: Applying materials. Overlap and apply carbon fiber woven fabric and angle yarn together, and sandwich an ABS filler layer 30 between the front of the two carbon fiber woven fabrics. When applying the prepreg, smooth it out to ensure there are no air bubbles or wrinkles, and there should be no foreign matter in the prepreg. After the prepreg is applied, attach an electronic cloth 23 to the head position of the angle yarn side of the prepreg. After attaching, apply the angle yarn side of the two materials together to form a prepreg bonding layer.

[0042] Step 3: Molding; According to the size of the prepreg, set up a hot press mold. After blowing away the impurities on the surface of the bonded prepreg layer with air, place it into the mold and place it correctly in the lower mold for about 30 seconds for preheating. After ensuring the precise placement of the prepreg bonded layer, close the mold. After closing the mold, set the molding conditions: temperature control at 135℃±5℃, molding time control at 40min±2min. After molding, cool to 18℃±5℃ before opening the mold. After cooling and curing, the initial eyeglass temple sheet is produced.

[0043] Step 4: Apply oil. Grind the surface of the initial eyeglass temple plate with 320-grit sandpaper, clean the surface of the ground initial eyeglass temple plate, and apply a layer of base oil. After applying the base oil, apply multiple layers of gold oil. After each layer of gold oil is applied, bake it in the oven to cure before applying more oil. Bake the sprayed product in an electric oven for 4 hours, with the baking temperature controlled at 75℃±5℃.

[0044] Step 5: Painting. After the product baked in Step 5 has cooled, use 600-grit sandpaper to grind the surface sand particles. Use a 100-grit belt sander to smooth the product edges. After sanding, clean the surface first, and then spray paint evenly on the surface to make the initial finished product of the eyeglass temple plate.

[0045] Step 6: Sanding and Cleaning. After the initial product of the temple plate is made, inspect the appearance for any rough defects or paint blistering. Sand it in sequence with 320-grit, 400-grit, and 600-grit sandpaper according to the thickness. The surface should be sanded evenly and smoothly without any unevenness. Finally, immerse the sanded product in a plastic frame containing detergent for a certain period of time, with the water temperature controlled at 80℃. After cleaning, the finished temple plate is produced. The plate used for the main body 10 of the temple is made through the above-mentioned material selection, pasting, molding, filling, oiling, painting, and sanding and cleaning processes. After cutting, the main body of the temple is formed. The clever use of a mold to set the core structure to create an opening structure makes it easier to fill the temple plate with the ABS filler layer 30.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
