[0001] This utility model relates to the field of electronic product accessories technology, and in particular to a 3D embossed cover plate. Background Technology

[0002] With the widespread use of electronic products and the increasing demands of consumers for aesthetic design, traditional flat glass covers can no longer meet market needs. 3D embossed covers, due to their unique three-dimensional aesthetics and tactile feel, are gradually becoming an important component of high-end electronic products. Currently, most 3D embossing on covers is prepared using etching. Patent application number CN201610850578.5 discloses a method for manufacturing a 3D embossed cover, which includes coating the surface of the cover with photoresist and performing a first curing, double-sided exposure of the photoresist and performing a second curing, developing the exposed photoresist and performing a third curing, and chemically etching the developed photoresist to form a 3D embossed pattern.

[0003] However, the etching method used in 3D relief carving involves a very large amount of etching on the cover plate, resulting in long processing time, high production costs, and an uneven surface after etching, requiring further polishing, which increases costs. Additionally, the large etched surface can affect the overall strength of the cover plate. Therefore, this invention discloses a 3D relief cover plate that solves these problems. Utility Model Content

[0004] Based on this, it is necessary to provide a 3D relief cover plate to address the aforementioned technical problems. A 3D relief is separately etched onto the relief cover plate, and then the relief cover plate is bonded and fixed to the main cover plate, thereby creating a cover plate with a 3D relief effect. The main cover plate retains its original structure and does not require etching, ensuring the overall strength of the main cover plate. Furthermore, the relief cover plate only needs to be larger than the area of ​​the 3D relief, greatly reducing the etching surface, reducing the amount of etching, shortening processing time, lowering production costs, and improving market competitiveness.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A 3D relief cover plate includes a main cover plate and a relief cover plate, wherein a 3D relief is etched on the relief cover plate and the relief cover plate is bonded and fixed to the main cover plate.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 should fall within the protection scope of the present invention.

[0028] As described in the background art, the etching method used in 3D relief carving involves a very large amount of etching on the cover plate, resulting in a long processing time, high production costs, and an uneven surface after etching, requiring further polishing, which increases costs. In addition, the large etched surface can affect the overall strength of the cover plate.

[0029] To solve this technical problem, this utility model provides a 3D embossed cover plate, which is applied in the field of electronic product accessories.

[0030] For details, please refer to Figure 1-6 The 3D relief cover plate specifically includes a main cover plate 1 and a relief cover plate 2. The relief cover plate 2 is etched with a 3D relief 3, and the relief cover plate 2 is bonded and fixed to the main cover plate 1.

[0031] The 3D relief cover plate provided by this utility model has a 3D relief 3 separately etched on the relief cover plate 2, and the relief cover plate 2 is bonded and fixed to the main cover plate 1, thereby producing a cover plate with the effect of 3D relief 3. The main cover plate 1 maintains its original structure and does not need to be etched, which ensures the overall strength of the main cover plate 1. Moreover, the relief cover plate 2 only needs to be larger than the area of ​​the 3D relief 3, which greatly reduces the etching surface, reduces the amount of etching, shortens the processing time, reduces the production cost, and improves market competitiveness.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] Example 1

[0036] Please refer to Figure 1-5 A 3D embossed cover plate is provided, comprising a main cover plate 1 and an embossed cover plate 2. Both the main cover plate 1 and the embossed cover plate 2 are glass covers, specifically tempered glass covers, but other materials such as polycarbonate covers can also be used. A 3D embossing 3 is etched on the embossed cover plate 2. The 3D embossing 3 can be a logo pattern, decorative pattern, or complex texture pattern. In this example, the 3D embossing 3 is a logo pattern. The specific pattern shape is prepared according to customer requirements. The etching process uses existing etching technology. Because the embossed cover plate 2 is small in size and requires little etching, the surface logo can be etched, making the manufacturing relatively simple. The embossed cover plate 2 is bonded and fixed to the main cover plate 1, thereby creating a cover plate structure with the 3D embossed 3 effect.

[0037] Furthermore, a positioning groove 4 is provided at the position where the 3D relief 3 needs to be set on the main cover plate 1. The positioning groove 4 is a shallow groove or a through groove. The positioning groove 4 is cut by chemical etching or laser cutting. The plane size of the positioning groove 4 is consistent with the plane size of the relief cover plate 2. The relief cover plate 2 is embedded in the positioning groove 4. The positioning groove 4 is used to position the relief cover plate 2, ensuring the fit and stability of the relief cover plate 2. At the same time, the corners of the relief cover plate 2 are rounded to avoid stress concentration at the corners of the relief cover plate 2 and breakage.

[0038] Furthermore, the thickness of the embossed cover plate 2 after etching is consistent with the depth of the positioning groove 4, and the surface of the embossed cover plate 2 with 3D relief 3 is flush with the surface of the main cover plate 1. After the embossed cover plate 2 is embedded in the positioning groove 4, only the 3D relief 3 protrudes from the surface of the main cover plate 1 to achieve a prominent display effect, making the product more textured and attractive.

[0039] Furthermore, the embossed cover plate 2 is bonded and fixed to the main cover plate 1 by a transparent adhesive layer 5. The transparent adhesive layer 5 is evenly laid on the bottom surface of the positioning groove 4 of the main cover plate 1, and then the embossed cover plate 2 is placed in the positioning groove 4, thereby bonding the embossed cover plate 2 to the main cover plate 1 together. In this example, the transparent adhesive layer 5 is an optical adhesive, specifically a UV adhesive, acrylic adhesive, or transparent epoxy resin adhesive, or it can be silicone or OCA adhesive. In this example, a UV adhesive is used. The UV adhesive is evenly coated on the main cover plate 1 or the embossed cover plate 2, and then the embossed cover plate 2 is bonded to the main cover plate 1. Ultraviolet light is then applied to fix the UV adhesive, thus bonding and fixing the embossed cover plate 2 to the main cover plate 1. The curing speed is fast, improving production efficiency.

[0040] Example 2

[0041] The 3D embossed cover plate provided in Embodiment 1 is further optimized, specifically, as follows: Figure 4-5As shown, the positioning groove 4 is a through groove penetrating the thickness direction of the main cover plate 1. A first step 6 is provided on one side of the positioning groove 4, and a second step 7 is provided on the embossed cover plate 2. The second step 7 of the embossed cover plate 2 is fitted with the first step 6, and a transparent adhesive layer 5 is provided on the transverse plane of the second step 7. The first step 6 is located on the side of the positioning groove 4 near the reverse side of the cover plate, and the second step 7 is located on the side of the embossed cover plate 2 near the 3D relief 3. Specifically, the positioning groove 4 extends outward from the back side of the main cover plate 1 to form the first step 6, and the front side of the embossed cover plate 2 contracts inward to form the second step 7. Both the first step 6 and the second step 7 are annular structures, and their dimensions are identical. The front side of the embossed cover plate 2 is inserted into the positioning groove 4 from the back side of the main cover plate 1, fitting the plane of the second step 7 with the plane of the first step 6, and is then bonded and fixed using the transparent adhesive layer 5. The step structure facilitates the limiting of the embossed cover plate 2 in the thickness direction of the main cover plate 1 and facilitates the bonding and fixing of the embossed cover plate 2. For some cover plate structures, ink patterns can be screen-printed on the back of the embossed cover plate 2, such as a black ink frame set around the edge of the embossed cover plate 2, or a colored ink layer screen-printed on the back of the embossed cover plate 2, thereby improving the color effect of the embossed cover plate 2 and increasing its aesthetics.

[0042] Example 3

[0043] The 3D embossed cover plate provided in Embodiment 2 is further optimized. Specifically, a protective coating 8 is coated on one surface of the embossed cover plate 2 where the 3D embossing 3 is located. The protective coating 8 covers the 3D embossing 3 and improves the wear resistance and anti-fouling performance of the surface of the embossed cover plate 2. The protective coating 8 is a UV-curable coating or an anti-fingerprint nano-coating, or both coatings can be layered to enhance the wear resistance and anti-fingerprint properties of the embossed cover plate 2. During preparation, the surface of the embossed cover plate 2 is first cleaned to ensure the adhesion of the coating. Then, the protective coating 8 is applied by spraying or dipping. Finally, a curing treatment is performed. For UV-curable coatings, ultraviolet light is used for curing.

[0044] The working principle of the 3D relief cover plate provided by this utility model is as follows: The main cover plate 1 is prepared according to conventional process. Then, a positioning groove 4 is opened on the main cover plate 1. The relief cover plate 2 is prepared according to the size of the positioning groove 4. Then, a 3D relief 3 is made on the relief cover plate 2 by etching process. A transparent adhesive layer 5 is coated. The relief cover plate 2 is embedded in the positioning groove 4. The transparent adhesive layer 5 is cured to bond the relief cover plate 2 and the main cover plate 1 together, thus producing a cover plate with the effect of 3D relief 3. The main cover plate 1 maintains its original structure and does not need to be etched, which ensures the overall strength of the main cover plate 1. Moreover, the area of ​​the relief cover plate 2 only needs to be larger than that of the 3D relief 3, which greatly reduces the etching surface, reduces the amount of etching, shortens the processing time, reduces the production cost, and improves market competitiveness.
