Detailed description of the invention

The embodiments of the present disclosure are described in detail below. The embodiments described below are exemplary, and are only used to explain the present disclosure, and should not be construed as limiting the present disclosure. Where specific techniques or conditions are not indicated in the examples, the procedures shall be carried out in accordance with the techniques or conditions described in the literature in the field or in accordance with the product specification. The reagents or instruments used without the manufacturer's indication are all conventional products that can be purchased commercially.

In one aspect of the present disclosure, the present disclosure provides a glass housing assembly. According to an embodiment of the present disclosure, refer to FIGS. 1 to 3 (wherein, FIG. 2 is a schematic diagram of the structure of the glass substrate, the dotted frame in FIG. 2 corresponds to the position of the relief texture of the three-dimensional pattern of the glass shell assembly, and FIG. 3 is FIG. 2 A cross-sectional view along AA′), the glass housing assembly includes: a glass substrate 10 having a concave-convex structure 11, and the concave-convex structure 11 is composed of a plurality of horizontal planes 111 connected by different lines; The first film 20, the first film 20 is arranged on one surface of the glass substrate 10; the UV texture layer 30, the UV texture layer 30 includes a spliced flat small texture 31 and a three-dimensional pattern relief texture 32. Therefore, the arrangement of the concave-convex structure can make the glass shell component have a three-dimensional outline of diamond texture, and the small flat texture can make the large surface of the glass shell component have the effect of moving with the light and looming texture (such as the Kevlar texture effect). The setting of the relief texture of the three-dimensional pattern can make the partial appearance of the glass shell assembly have a three-dimensional relief pattern, enhance the overall three-dimensional visual effect of the glass shell assembly, and bring a different visual experience to the user.

Among them, the glass substrate is prepared by 3D hot pressing, hot forging or glass heat absorption method, so as shown in Figure 3, the glass substrate is of equal thickness, that is, within the allowable range of process error, the glass substrate The thickness of the bar at different positions is uniform. In some embodiments, the thickness of the glass substrate is 0.6-0.8 mm, and Corning GG5 glass is used. Further, the horizontal surface of the concave-convex structure is a smooth surface. In this way, the glass housing assembly has a better gloss, so as to improve the overall appearance of the housing assembly.

Wherein, with respect to the reference surface 112 of the glass substrate 10, the protrusion height D1 of the uneven structure 11 is 0.5 to 1.0 mm (for example, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm), and the uneven structure 11 The depth of the depression (not shown in Figure 3) is 0.5 to 1.0 mm (for example, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm). Therefore, the concave structure of the above-mentioned size can make the glass housing assembly have a better three-dimensional diamond texture, and will not make the concave-convex structure too abrupt and affect the touch of the glass housing assembly. It should be noted that, with respect to the reference surface, the concave-convex structure may have only protrusions, or both protrusions and depressions. Those skilled in the art can design flexibly according to actual conditions such as the pattern structure of the concave-convex structure.

Since the glass substrate has an outer surface (the surface close to the exterior surface of the glass housing assembly) and an inner surface (the surface away from the exterior surface of the glass housing assembly, that is, the surface near the first diaphragm), the glass substrate is equal to Regardless of the thickness, whether it is the outer surface or the inner surface, as shown in Figure 3, there are multiple horizontal planes connected by different lines, and the horizontal planes of the inner surface and the outer surface are parallel to each other.

Further, as shown in FIGS. 3 and 4 (FIG. 4 is an enlarged view in a dashed circle frame in FIG. 3), the included angle α between two adjacent horizontal planes 111 is 110°-170° (for example, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°). As a result, the transition transition between adjacent horizontal planes is relatively smooth and will not be too steep, otherwise it will affect the touch of the housing assembly; if α is less than 110°, the transition transition between two adjacent horizontal planes will be relatively steep and serious Affect the hand feeling of the glass shell components, and the post-production process will affect the decoration film layer (that is, the film with the structure of UV texture, color layer, coating layer, etc.) lamination and other processing; if α is greater than 170°, then The transition transition between two adjacent horizontal planes is relatively too smooth, and the protrusions or depressions are not obvious, thereby affecting the diamond texture effect of the glass shell assembly. Further, as shown in Figures 3 and 4, on the inner surface of the glass substrate, there is an R angle between two adjacent horizontal planes, and the radius r of the R angle is 0.5mm～1.0mm (such as 0.5mm, 0.6mm, , 0.7mm, 0.8mm, 0.9mm, 1.0mm). Thus, not only can the diamond texture of the glass substrate have a better three-dimensional visual perception, but also a good bonding effect between the glass substrate and the later decorative film layer can be ensured; if the radius r of the R angle is less than 0.5mm, Then the transition transition between two adjacent horizontal planes will be relatively steep and sharp, and the post-production process will affect the decoration film layer (that is, the film with UV texture, color layer, coating layer and other structures) lamination and other processing Production; If the radius r of the R angle is greater than 1.0mm, the ridgeline of the transition transition between two adjacent horizontal planes in the uneven structure is relatively smooth, resulting in a relatively poor stereoscopic vision of the diamond texture. Wherein, on the outer surface of the glass substrate, the radius r'of the R angle between two adjacent horizontal planes is the sum of the inner surface R angle radius r and the thickness of the glass substrate.

Wherein, on the surface of the glass substrate close to the first diaphragm, a character pattern, such as a LOGO pattern (such as characters such as OPPO) may be further silk-printed.

Further, the specific material of the first diaphragm has no special requirements, and those skilled in the art can flexibly choose according to actual needs. In some embodiments, the material of the first diaphragm includes, but is not limited to, PET, TPU, PC and other materials.

Further, as shown in FIG. 1, the thickness of the flat small texture 31 is 8-12 microns (for example, 8 microns, 9 microns, 10 microns, 11 microns or 12 microns), and the three-dimensional pattern relief texture 32 has a thickness of 10-15 microns ( 10 microns, 11 microns, 12 microns, 13 microns, 14 microns or 15 microns). The thickness of the three-dimensional pattern embossed texture 32 is greater than the thickness of the flat small texture 31. When the user views the three-dimensional pattern embossed texture of the glass housing assembly, the pattern embossed texture has a strong three-dimensional effect, thereby enhancing the overall three-dimensional visual sense of the appearance of the glass housing assembly.

Among them, the three-dimensional pattern embossed texture and the flat small texture are prepared by the method of laser direct writing. Compared with UV transfer and other methods, it can further improve the delicacy of the UV texture layer and make the three-dimensional pattern embossed texture more three-dimensional. Stronger, resulting in high yield and low cost of the UV texture layer, which is suitable for mass production.

Further, there is no restriction on the specific pattern of the relief texture of the three-dimensional pattern, and those skilled in the art can flexibly choose according to actual needs. In some embodiments, the specific pattern of the relief texture of the three-dimensional pattern may be a brand LOGO, such as a Lamborghini logo.

Therefore, the arrangement of the first coating layer helps to improve the glossiness of the relief texture of the three-dimensional pattern, and by adjusting the material and thickness of the first coating layer, the first coating layer can show the desired color (such as gold). A suitable color substrate is provided for the three-dimensional pattern relief texture, and the selection of specific colors can be flexibly selected by those skilled in the art according to the requirements of the three-dimensional pattern relief texture.

Wherein, the material of the first coating layer includes but is not limited to at least one of silicon nitride, silicon oxide, niobium oxide, and thallium oxide.

Therefore, the arrangement of the first ink layer can better protect the relief texture of the three-dimensional pattern, and at the same time ensure a good appearance effect of the relief texture of the three-dimensional pattern.

Wherein, the first ink layer may include multiple (for example, two) first sub-ink layers, which can facilitate the preparation of the first ink layer with a suitable thickness, so as to better protect the relief texture of the three-dimensional pattern. There is no special requirement for the color of the first ink layer, as long as it can provide a better covering and light leakage effect. For example, the color of the first ink layer can be black or white.

According to an embodiment of the present disclosure, referring to FIG. 6, the glass housing assembly further includes: a second coating layer 60. The second coating layer 60 is disposed on the side of the first coating layer 40 away from the glass substrate 10 (when the glass housing assembly When including the first ink layer 50, the second coating layer 60 is provided on the surface of the first ink layer 50 away from the glass substrate 10), and the orthographic projection on the glass substrate 10 covers the UV texture 30 on the glass substrate 10 Orthographic projection on. As a result, the second coating layer has a highly reflective effect, which can effectively improve the glossiness of the appearance of the glass housing assembly.

Wherein, the specific material of the second coating layer is selected from at least one of indium and tin. The thickness of the second coating layer is 55nm～65nm (such as 55nm, 57nm, 59nm, 60nm, 61nm, 63nm, 65n). Therefore, the second coating layer has better high reflectivity and can improve the glass shell well. The overall gloss and texture effect of the component appearance.

According to an embodiment of the present disclosure, referring to FIG. 9, the glass housing assembly further includes a second ink layer 52, and the second ink layer 52 is disposed on the surface of the second coating layer away from the first diaphragm 20. Therefore, the arrangement of the second ink layer can provide a better light shielding effect for the glass housing assembly, so as to prevent the housing assembly from leaking light and affect the appearance of the glass housing assembly.

In another aspect of the present disclosure, the present disclosure provides a method of manufacturing the aforementioned glass housing assembly. According to an embodiment of the present disclosure, referring to FIG. 10, a method of manufacturing a glass housing assembly includes:

S100: Prepare a glass substrate 10 with a concave-convex structure 11 by a 3D hot pressing, hot forging or glass heat absorption method, wherein the concave-convex structure 11 is composed of multiple horizontal planes 111 connected by different lines. Refer to Figures 2 and for the schematic diagram of the structure. image 3.

Among them, first obtain a 2D white sheet of a specified size through cutting, CNC and other processes, and then use a special hot bending mold to heat forming a 3D diamond texture with a specified shape design.

Further, the temperature of the 3D hot pressing is 780℃～850℃ (such as 780℃, 790℃, 800℃, 810℃, 820℃, 830℃, 840℃, 850℃), and the pressure is 110kg～130kg (such as 110kg, 115kg, 120kg, 125kg, 130kg). Compared with the conventional 3D process, the hot pressing temperature of the present disclosure is 20-30°C higher, and the hot pressing pressure is 20-30kg higher, which can effectively ensure the good molding effect of the lines in the concave-convex structure; if the temperature is lower than 780°C Or the pressure is lower than 110kg, it is relatively unfavorable for the formation of the concave-convex mechanism, resulting in the inconspicuous lines connecting different planes in the concave-convex structure, thereby reducing the three-dimensional perception of the glass shell assembly; if the temperature is higher than 850℃ or the pressure is higher than 130kg, the heat During the pressing process, the mold will leave a deep impression or orange pattern on the surface of the glass substrate.

Further, the temperature of hot forging is 780℃～850℃ (such as 780℃, 790℃, 800℃, 810℃, 820℃, 830℃, 840℃, 850℃), and the pressure is 110kg～130kg (such as 110kg, 115kg). , 120kg, 125kg, 130kg). As a result, a good molding effect of the lines in the uneven structure can be effectively ensured, and the three-dimensional visual sense of the uneven structure can be improved. If the temperature is lower than 780℃, it is relatively unfavorable for the formation of the concave-convex mechanism, resulting in inconspicuous lines connecting different planes in the concave-convex structure, thereby reducing the three-dimensional effect of the glass shell assembly; if the temperature is higher than 850℃, it will be in the hot forging process. , The molding effect of the concave-convex structure will be relatively poor.

Further, the heat absorption temperature of the glass is 740°C to 800°C (for example, 740°C, 750°C, 760°C, 770°C, 780°C, 790°C, 800°C). Therefore, within the above-mentioned temperature range, a good molding effect of the lines in the uneven structure can be effectively ensured, and the three-dimensional visual sense of the uneven structure can be improved.

Further, after hot pressing to obtain the 3D diamond texture of the concave-convex structure, rough polishing is performed on the concave and convex surfaces of the glass substrate, specifically: black nylon glue wire (diameter 0.3mm) is used for polishing for 35 to 45 minutes, by This polishing treatment has a high polishing efficiency, and at the same time, it effectively polishes the ridge lines of the concave-convex structure and removes the surface indentation and orange lines. After rough polishing, the concave and convex surfaces of the glass substrate are polished. Specifically: white nylon glue wire (diameter of 0.15mm) is used for polishing for 25 to 35 minutes, so the polishing treatment further improves the surface quality of the glass substrate and reduces the scratches on the glass surface.

Further, after the glass substrate is polished, the glass substrate is further strengthened, specifically: the polished glass substrate is placed in a strengthening salt bath, and the mass fraction of the first strengthening use is 62 % KNO ₃ and 38% NaNO ₃ mixed strengthening liquid, strengthening time is 120min, strengthening temperature is 380℃; the second strengthening uses 91% KNO ₃ and 38% NaNO ₃ , strengthening time is 38min , Strengthening temperature is 380℃. Strengthen the glass substrate through strengthening treatment.

Wherein, with respect to the reference surface 112 of the glass substrate 10, the protrusion height D1 of the uneven structure 11 is 0.5 to 1.0 mm (for example, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm), and the uneven structure 11 The depth of the depression (not shown in Figure 3) is 0.5 to 1.0 mm (for example, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm). Therefore, the concave structure of the above-mentioned size can make the glass shell assembly have a better three-dimensional diamond texture, and will not make the concave-convex structure too abrupt and affect the touch of the glass shell assembly. It should be noted that, with respect to the reference surface, the concave-convex structure may have only protrusions, or both protrusions and depressions. Those skilled in the art can design flexibly according to actual conditions such as the pattern structure of the concave-convex structure.

Further, as shown in FIGS. 3 and 4 (FIG. 4 is an enlarged view in a dashed circle frame in FIG. 3), the included angle α between two adjacent horizontal planes 111 is 110°-170° (for example, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°). As a result, the transition transition between adjacent horizontal planes is relatively smooth and will not be too steep, otherwise it will affect the touch of the housing assembly; if α is less than 110°, the transition transition between two adjacent horizontal planes will be relatively steep and serious Affect the hand feeling of the glass shell components, and the post-production process will affect the decoration film layer (that is, the film with the structure of UV texture, color layer, coating layer, etc.) lamination and other processing; if α is greater than 170°, then The transition transition between two adjacent horizontal planes is relatively too smooth, and the protrusions or depressions are not obvious, thereby affecting the diamond texture effect of the glass shell assembly.

Further, as shown in Figures 3 and 4, there is an R angle between two adjacent horizontal planes, and the radius r of the R angle is 0.5mm～1.0mm (such as 0.5mm, 0.6, mm, 0.7mm, 0.8mm, 0.9 mm, 1.0mm). Thus, not only can the diamond texture of the glass substrate have a better three-dimensional visual perception, but also a good bonding effect between the glass substrate and the later decorative film layer can be ensured; if the radius r of the R angle is less than 0.5mm, Then the transition transition between two adjacent horizontal planes will be relatively steep and sharp, and the post-production process will affect the decoration film layer (that is, the film with UV texture, color layer, coating layer and other structures) lamination and other processing Production; if the radius r of the R angle is greater than 1.0mm, the stereoscopic vision of the diamond texture will be relatively poor.

Further, in the subsequent steps, before the glass substrate is attached to the diaphragm (the first diaphragm or the second diaphragm), a character pattern can be silk-printed on the surface of the glass substrate close to the first diaphragm in advance, such as LOGO pattern (such as OPPO and other characters). In some specific embodiments, a polyester screen with low screen tension (13-15N) is used, and the squeegee adopts a profiling squeegee (designed according to the glass shape) to ensure that the LOGO pattern is screen-printed in a non-planar area and that there is no obvious Fatty oil phenomenon.

S200: Use laser direct writing technology to separately produce small flat textures and three-dimensional pattern relief textures to form a UV texture layer (that is, including small flat textures and three-dimensional relief textures), and transfer the UV texture layer to one of the first film On the surface. The prepared small flat textures move with the light on the exterior surface of the glass shell assembly and are looming. The three-dimensional embossed texture provides a unique three-dimensional appearance pattern for the shell assembly, and it can further improve the UV texture compared to methods such as UV transfer.

Therefore, under the above-mentioned conditions, small flat textures and three-dimensional pattern embossed textures with better texture effects can be prepared.
