Description

Technical Field

[0001] This invention relates to the field of eyewear technology, and in particular to an eyewear structural component and its manufacturing method, as well as an eyewear assembly. Background Technology

[0002] Traditional tortoiseshell-like eyeglasses primarily use CA (cellulose acetate) sheets, machined using CNC machining. However, this process suffers from low efficiency and difficulty in forming complex thin-walled structures, making it unsuitable for the complex thin-walled components of smart glasses. Currently, smart glasses structural components with tortoiseshell-like appearances are mainly manufactured using the following molding method: first, plastic particles are injection molded, and then surface treatment techniques such as dotting and dyeing are used to impart texture effects. However, the texture effect obtained by this molding method exists only on the surface of the product, lacking sufficient textural depth and transparency, resulting in a poor visual effect. Summary of the Invention

[0003] The main objective of this invention is to provide a spectacle structural component and its manufacturing method, as well as a spectacle assembly, with the aim of improving the visual appearance of the spectacle structural component.

[0004] To achieve the objective of this invention, this invention provides a method for manufacturing a spectacle structural component, comprising the following steps: Provide at least two different colors of plastic particles; The plastic particles are mixed and hot-pressed to obtain a structural component product body and a skirt structure, wherein the skirt structure is connected to the periphery of the structural component product body, and the structural component product body has a body-like texture extending from the surface to the interior. Remove the skirt structure to obtain the main body of the structural component product, which is an eyeglass structural component.

[0005] In one embodiment, the plastic particles include transparent plastic particles and at least one colored plastic particle, or at least two different colored plastic particles.

[0006] In one embodiment, the color of the pigment in the colored plastic particles includes at least one of black, yellow, red, and brown, and the eyeglass structure is a tortoiseshell eyeglass structure.

[0007] In one embodiment, the step of mixing the plastic particles and hot-pressing them to obtain the main body and skirt structure of the structural component includes: The plastic particles are mixed and put into a hot pressing mold for hot pressing to obtain the main body and skirt structure of the structural component. The hot pressing temperature is 150℃~300℃, the pressure is 10MPa~150MPa, and the holding time is 15s~300s.

[0008] In one embodiment, the hot pressing mold includes a cavity, an overflow groove disposed around the periphery of the cavity and communicating with the cavity, and a skirt body forming area communicating with the other side of the overflow groove. The cavity is used to form the main body of the structural component, and the overflow groove and the skirt body forming area are used to form the skirt structure. The depth of the overflow groove is less than the depth of the skirt body forming area.

[0009] In one embodiment, the cavity includes a main cavity and a functional structural cavity connecting the main cavity. The main cavity is used to form the main body of the structural component product body, and the functional structural cavity is used to form the functional structural part of the structural component product body.

[0010] In one embodiment, the hot pressing mold includes a plurality of spaced cavities, and each cavity is provided with an overflow groove and a skirt body forming area around its periphery.

[0020] Currently, eyeglass structural components with specific appearance effects such as those mimicking tortoiseshell are mainly manufactured using the following molding method: first, plastic particles are injection molded, and then surface treatment techniques such as dotting and dyeing are used to give them an appearance texture effect. However, the appearance texture effect of the product obtained by this method exists only on the surface layer of the product, lacking sufficient texture layering and transparency, resulting in a poor visual effect.

[0021] To address the aforementioned technical problems, this invention provides a method for manufacturing a structural component for eyeglasses. The structural component can be a component of traditional eyeglasses or a component of smart eyeglasses, and is not limited thereto. The structural component includes, but is not limited to, the front frame and temples.

[0022] Reference Figure 1 In one embodiment of the present invention, the method for preparing the eyeglass structural component includes the following steps: Step S1: Provide at least two different colored plastic particles.

[0023] In step S1, the plastic particles of different colors include, but are not limited to, transparent plastic particles, translucent plastic particles, and colored plastic particles. Transparent plastic particles include a transparent substrate, translucent plastic particles include a translucent substrate, and colored plastic particles include a plastic substrate and a corresponding color powder. The specific types of raw materials used in these plastic particles are not limited and are all within the scope of protection of this invention. Furthermore, all the plastic particles are prepared using a granulation process, and the specific process operation is not limited. The shape and size of the plastic particles are also not limited and are all within the scope of protection of this invention.

[0024] Step S2 involves mixing the plastic particles and hot-pressing them to obtain the main body of the structural component and the skirt structure. The skirt structure is connected to the periphery of the main body of the structural component, which has a body-like texture extending from the surface to the interior.

[0025] Specifically, plastic particles of different colors are mixed evenly and then placed into a thermoforming mold for one-time thermoforming, directly pressing them into the main body of the structural component and the skirt structure connecting its periphery. The main body of the structural component is the finished eyeglass structural component. During the thermoforming process, the thermopressor heats the plastic particles to a molten state, applies pressure to make them flow fully and evenly fill the entire cavity within the mold cavity, thus forming an eyeglass structural component with a complex three-dimensional structure in one step. In this process, a natural and transparent flowing texture is formed inside the main body of the structural component, and the texture extends from the surface to the interior, achieving a holistic presentation of the texture effect and solving the technical defect of traditional surface treatment processes where the texture only exists on the surface.

[0026] It should be noted that, in order to ensure that the cavity is completely filled during the hot pressing process to improve the product's precision, while molding eyeglass structural parts with complex three-dimensional structures, excess material will flow into the periphery of the cavity and simultaneously form a skirt structure.

[0027] Step S3: Remove the skirt structure to obtain the main body of the structural component product, which is the eyeglass structural component.

[0028] Specifically, after hot pressing is completed, the mold is opened and the main body of the structural component with the skirt structure is taken out. The operator manually or with the help of simple tools removes the skirt structure along the connection between the main body of the structural component and the skirt structure to obtain the complete main body of the structural component, which is the eyeglass structural component.

[0029] It should be noted that after removing the skirt structure, there may be minor burrs or marks around the perimeter of the main body of the structural component. However, these burrs or marks are located on non-appearance or assembly surfaces of the product and do not affect the appearance quality or assembly and use of the product.

[0030] Compared to CNC finishing, removing the skirt structure requires no specialized equipment, programming, debugging, or clamping, greatly simplifying the process, shortening the production cycle, and reducing production costs. Furthermore, it eliminates the need for additional surface treatment processes such as speckling and dyeing, reducing chemical usage and energy consumption, further lowering production costs. Simultaneously, removing the skirt structure generates no cutting waste, and all excess material can be recycled, improving material utilization and meeting the requirements of green manufacturing.

[0031] The present invention provides a method for preparing eyeglass structural components. This method involves mixing at least two different colored plastic particles and combining them with a one-time hot-press molding process. This process promotes the full expansion, flow, and shaping of the surface texture within the material, thereby creating a body-like texture effect that extends from the surface to the interior of the material. Compared to existing surface treatment processes, the eyeglass structural components obtained by the present invention exhibit richer and more natural surface textures, significantly improving their visual effect and appearance quality. Furthermore, the present invention directly prepares eyeglass structural components using a one-time hot-press molding process, eliminating the need for CNC precision machining and insert injection molding. Only the skirt structure needs to be simply removed to obtain the product. This process significantly shortens the production flow and reduces the production cycle from raw materials to finished products, thereby improving production efficiency while reducing labor and equipment costs.

[0032] In some embodiments, the plastic particles include transparent plastic particles and at least one colored plastic particle, or at least two different colored plastic particles. The color of the pigment in the colored plastic particles can be one of a variety of colors such as amber, brown, black, yellow, red, blue, pink, green, and gray, all of which are within the scope of protection of this invention.

[0033] By mixing transparent plastic particles with at least one colored plastic particle, or mixing at least two different colored plastic particles, and combining them with a one-time hot pressing process, it is possible to make the substrate or color powder with different colors and appearances evenly distributed inside the main body of the structural component. After molding, the texture extends from the surface to the interior of the material, realizing the ontological presentation of the texture effect.

[0034] In the thermoforming process, plastic particles of different colors are used. These materials permeate, blend, and flow, forming irregular and random textures that realistically simulate the visual effects of natural materials. The particles are not completely uniformly mixed in the molten state; instead, they create natural transitions and interweaving between colors. This results in a rich sense of color depth and variation in shade and intensity, significantly enhancing the product's appearance. Different colored plastic particles produce different refraction and reflection effects under light, especially noticeable when using translucent substrates. The mixing of multi-colored plastic particles causes complex scattering and transmission of light within the material, enhancing its visual three-dimensionality and transparency, making the product appear more dynamic and textured.

[0035] It should be noted that by adjusting the ratio, particle size, and distribution of plastic particles of different colors, various texture effects can be flexibly designed to meet diverse aesthetic needs.

[0036] In some embodiments of the present invention, the color of the pigment includes at least one of amber, brown, black, yellow, red, blue, pink, green, and gray. The specific color of the pigment can be flexibly adjusted according to the requirements, and one, two, or a mixture of more than two of the above colors can be selected.

[0037] In some embodiments of the present invention, the plastic substrate for the colored plastic particles may be a transparent substrate, a translucent substrate, or an opaque substrate, without limitation, all of which are within the scope of protection of the present invention. Specifically, the plastic substrate includes at least one of cellulose acetate (CA), polycarbonate (PC), polyamide (PA), polyethylene terephthalate-1,4-cyclohexanediol (PCTG), polystyrene (PS), and polymethyl methacrylate (PMMA).

[0038] In some embodiments of the present invention, the plastic particles further include at least one of pearlescent powder and mica powder. Pearlescent powder and mica powder are visual texture effect additives that can interact with light to produce unique optical effects. This makes the product present changing light and shadow effects from different viewing angles, thereby enhancing the visual depth and three-dimensionality of the material and making the appearance texture more realistic and dynamic.

[0039] In some embodiments of the present invention, the color of the pigment in the colored plastic particles includes at least one of black, yellow, red, and brown, and the eyeglass structure is a tortoiseshell eyeglass structure.

[0040] Specifically, to simulate the unique texture of tortoiseshell, transparent plastic particles are mixed with at least one colored plastic particle or at least two different colored plastic particles and then subjected to one-time hot pressing. During the molding process, the transparent plastic particles and colored plastic particles, or colored plastic particles of different colors, intertwine in the molten flow, thereby forming a tortoiseshell-like structural component product body and skirt structure with natural texture. The color powder in the colored plastic particles includes one, two, or more of black, yellow, red, and brown. The specific ratio of transparent plastic to colored plastic particles, and the specific ratio of different colored plastic particles, can be flexibly adjusted according to design requirements and are not limited herein, all of which are within the scope of protection of this invention.

[0041] By controlling the molding temperature, pressure, and holding time, the flow pattern and distribution density of the texture can be adjusted, so that each product presents a unique tortoiseshell texture effect.

[0042] In some embodiments of the present invention, the hot pressing temperature is 150°C to 300°C, such as 150°C, 180°C, 200°C, 220°C, 250°C, 280°C, 300°C, and any range between two endpoints; the pressure is 10MPa to 150MPa, such as 10MPa, 30MPa, 50MPa, 80MPa, 100MPa, 150MPa, and any range between two endpoints; the holding time is 15s to 300s, such as 15s, 50s, 100s, 200s, 300s, and any range between two endpoints.

[0043] The hot pressing temperature, meeting the aforementioned range, effectively ensures that the plastic particles reach a molten state, guaranteeing thorough melting and fusion of the material. The combination of the pressure range and temperature allows the molten particles to interlock and intertwine during flow, resulting in a fine, continuous, and layered texture while improving surface smoothness and dimensional accuracy. The holding time, meeting the aforementioned range, allows the molten material to release stress and undergo initial cooling and shaping under pressure, ensuring the final product maintains dimensional stability while achieving rapid molding.

[0044] It should be noted that the temperature, pressure, and holding time of hot pressing can be flexibly adjusted according to the complexity of the product structure and the wall thickness.

[0045] In some embodiments, in step S2, the hot pressing mold includes a cavity, an overflow groove disposed around the cavity and connected to the cavity, and a skirt body forming area connected to the other side of the overflow groove. The cavity is used to form the main body of the structural component product, and the overflow groove and the skirt body forming area are used to form the skirt structure. The depth of the overflow groove is less than the depth of the skirt body forming area.

[0046] The cavity is used to form the main body of the structural component (i.e., the eyeglass structural component). When designing the molding die, the cavity design matches the outer contour of the final product (i.e., the eyeglass structural component). An overflow groove is located around the periphery of the cavity and communicates with it. The skirt body forming area is located on the side of the overflow groove away from the cavity and communicates with it. With this arrangement, during the hot pressing process, excess material flows into the overflow groove around the cavity and into the skirt body forming area, forming a skirt structure. The formed skirt structure includes a connecting part and a skirt body part. The connecting part is formed through the overflow groove, meaning the overflow groove is designed to match the outer contour of the connecting part; the skirt body part is formed through the skirt body forming area, meaning the skirt body forming area is designed to match the outer contour of the skirt body part.

[0047] Since the depth of the overflow groove is less than the depth of the skirt body forming area, the thickness of the connecting part in the resulting skirt structure is less than the thickness of the skirt body. As a result, the skirt structure can be easily removed, meaning that the operator can directly break off the skirt structure, making the operation easier and simpler.

[0048] By rationally designing the specific structure of the hot pressing mold, the embodiment of the present invention can directly obtain the main body of the structural component with the above-mentioned skirt structure. Subsequently, only the skirt structure needs to be removed to obtain the product. The process is simple, the production efficiency is high, and the production cost is low.

[0049] Both the overflow groove and the skirt body forming area can be annular structures, with their inner and outer sides connected to the skirt body forming area and the cavity, respectively. Alternatively, both the overflow groove and the skirt body forming area can be separate structures, with multiple overflow grooves distributed at intervals along the circumference of the cavity. Multiple skirt body forming areas are correspondingly located on the outer sides of the multiple overflow grooves, and each overflow groove has its two sides connected to both the skirt body forming area and the cavity, respectively. The specific shape and size of the overflow groove and the skirt body forming area are not limited herein and are all within the scope of protection of this invention.

[0050] In some embodiments, in step S2, the cavity of the hot pressing mold includes a main cavity and a functional structural cavity connecting the main cavity. The main cavity is used to form the main body of the structural component product, and the functional structural cavity is used to form the functional structural part of the structural component product.

[0051] Specifically, the main body of the structural component (i.e., the eyeglass structural component) includes a main body and a functional structural part. The main body can be either the temple body or the front frame body. The functional structural part includes, but is not limited to, complex structures such as hinge mounting slots, screw holes, wiring slots, snap-fit ​​positions, and electronic component housings. When designing the cavity of the thermoforming mold, based on the specific structure of the eyeglass structural component, a main body cavity matching the outer contour of its main body and a functional structural cavity matching the outer contour of its functional structural part are designed. By using the aforementioned precise thermoforming mold design, the eyeglass structural component can be formed in one step, achieving integrated molding of appearance and function. This eliminates the need for subsequent CNC precision machining and insert injection molding, ensuring the precision and assembly reliability of the eyeglass structural component.

[0052] This invention utilizes precision molds to form the final product in a single process. The product's dimensions and appearance are guaranteed by the mold, resulting in batch-to-batch consistency far superior to CNC machining and surface treatment processes. For eyeglass structural components of different shapes and sizes, production can be quickly switched simply by changing the mold, offering high flexibility and excellent process compatibility.

[0053] It should be noted that the specific structure of the hot pressing mold is not limited. As long as the cavity, overflow groove and skirt body forming area have the above structure, they are all within the protection scope of this invention.

[0054] In some embodiments, the hot pressing mold includes multiple spaced cavities, each cavity having an overflow groove and a skirt body forming area around its periphery. The specific arrangement of the cavities, overflow grooves, and skirt body forming areas can be referred to the above embodiments, and will not be repeated here.

[0055] In this embodiment of the invention, the hot pressing mold is provided with multiple cavity structures, that is, the multi-cavity mold is used for production, which can simultaneously form multiple structural parts, improve the efficiency of mass production, and has good process compatibility.

[0056] In some embodiments of the present invention, after the step of removing the skirt structure, a surface treatment is further included, which includes grinding and polishing.

[0057] Specifically, firstly, fine sandpaper is used to polish away the fine burrs left after removing the skirt structure to eliminate processing marks; then, mechanical polishing is performed to achieve a mirror-like gloss on the surface.

[0058] Furthermore, in an optional embodiment, the surface treatment also includes applying a transparent abrasion-resistant coating. Specifically, a transparent coating is sprayed onto the polished surface to improve the product's scratch resistance, weather resistance, and surface gloss, while protecting the internal texture from external environmental erosion and extending the service life of the eyeglass structural components.

[0059] This invention also provides a spectacle structural component, which is prepared using the aforementioned method. This method involves mixing at least two different colored plastic particles and combining them with a one-time hot-press molding process, causing the surface texture to fully expand, flow, and solidify within the material, thereby creating a body-like texture effect extending from the surface to the interior of the material. Compared to existing surface treatment processes, the spectacle structural component obtained by this invention has a richer, more transparent, and natural surface texture, significantly improving its visual effect and appearance quality. Therefore, the spectacle structure prepared by this invention balances high-quality visual appeal with adaptability to complex structures.

[0060] The present invention also provides an eyeglass assembly, which includes a lens and an eyeglass structural component. The specific structure of the eyeglass structural component is as described in the above embodiments. Since the eyeglass assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
