[0060] Figure 10 This is a flowchart illustrating a shell processing method according to an exemplary embodiment. Detailed Implementation

[0061] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0062] In related technologies, with the continuous development of the electronics industry, electronic product manufacturers have proposed glossy housing 1', matte housing 2', and glossy / matte integrated housing 3' (see reference). Figures 1-3 The design concept shown provides users with shells that offer different aesthetic effects.

[0063] Among them, the matte shell and the matte-gloss hybrid shell have an uneven, rough surface, which reduces the light reflectivity from 8% to 1%, thereby reducing glare and reflection and enhancing the shell's premium feel. However, the standard thickness of the shell is 0.4mm-0.5mm, and forming a rough surface will reduce the shell's strength.

[0064] Some electronic product manufacturers have increased the thickness of the casing to more than 0.7mm. However, during the casing processing, the increased thickness makes the casing prone to chipping or breaking, reducing the yield rate to 100% and increasing the cost of casing processing.

[0065] This disclosure proposes a shell processing method. The method includes providing a material plate with processing and non-processing areas, setting a protective layer in the non-processing area, etching the material plate with the protective layer to form a matte layer on the surface of the processing area, removing the protective layer to form a target material plate, and processing the target material plate to form the shell. In this disclosure, the protective layer is removed before processing the target material plate, effectively preventing the protective layer from contaminating the target material plate and affecting subsequent process steps. This improves the shell strength, reduces the occurrence of edge chipping or breakage, and increases the shell production yield. Furthermore, the protective layer, combined with the etching of the material plate, forms a matte layer in the processing area, achieving a seamless matte finish on the shell, enhancing its aesthetics and premium feel.

[0066] In one exemplary embodiment, a housing processing method is provided for processing a housing, such as the housing of an electronic device. Figure 7 As shown, the shell processing method in this embodiment includes:

[0067] S110, Provide material plates.

[0068] In this step, such as Figure 4As shown, raw materials are selected and cut using a cutting machine to divide them into as many pieces of the same size as possible. Any one piece is selected and cut again to produce n material plates 1. These n material plates 1 are then processed. A production line can process multiple material plates 1 simultaneously, each using the same processing method. This embodiment uses one material plate 1 as an example, where one material plate 1 corresponds to the casing of one electronic device.

[0069] The raw material can be 0.8mm thick glass, which has a strong signal transmission capability when installed in electronic devices, ensuring normal signal transmission. Furthermore, due to its superior signal transmission capability, it avoids obstructing power flow and improves charging speed when electronic devices use wireless charging.

[0070] It should be noted that the thickness of the raw material is not limited to 0.8 mm. The above is only an illustrative example and does not constitute a limitation on this application.

[0071] The material plate 1 has a non-processing area 11 and a processing area 12, which are referenced Figure 4 As shown, the shaded area is the unprocessed area 11, and the non-shaded area is the processed area 12. The processed area 12 is used for processing to achieve a matte finish.

[0072] S120. Install a protective layer in non-processing areas.

[0073] In this step, such as Figure 4 As shown, a protective layer is provided in the non-processed area 11 to protect the non-processed area 11 and ensure that the surface of the non-processed area 11 is smooth. The protective layer can be, for example, ink.

[0074] In the specific implementation process, the material plate 1 is placed in the screen printing fixture, and a protective layer is formed on the surface of the non-processed area 11 by coating according to the shell requirements through the screen printing screen.

[0075] S130. The material plate with a protective layer is etched to form a matte layer on the surface of the processing area.

[0076] In this step, such as Figure 4 As shown, the material plate 1 is etched to form a matte layer on the surface of the processed area 12. The protective layer protects the non-processed area 11 from corrosion, ensuring that the non-processed area 11 has a glossy surface, thus achieving a combined matte and glossy effect.

[0077] S140, Remove the protective layer to form the target material plate.

[0078] In this step, the protective layer is removed, exposing the smooth surface of the material plate to form the target material plate. Specifically, the material plate is placed in a chemical bath and immersed in a third etching solution for a second preset time, accompanied by agitation and cleaning to remove the protective layer and form the target material plate. The third etching solution is made of a strong alkaline material, and the second preset time is 2.5-3.5 minutes. After cleaning, the target material plate undergoes a reflective inspection to prevent any protective layer residue from remaining on its surface and affecting its processing.

[0079] S150. Process the target material plate to form a shell.

[0080] In this step, the target material plate is further processed to form a shell.

[0081] In this embodiment, a protective layer is pre-set in conjunction with an etching process to form a matte layer, completing the initial processing. After the initial processing, the protective layer is removed to form the target material plate. The target material plate without a protective layer is further processed to form a shell, preventing the protective layer from affecting the shell's strength, reducing the occurrence of shell chipping or breakage, and improving the shell production yield.

[0082] In one exemplary embodiment, a housing processing method is provided for processing a housing, such as the housing of an electronic device. Figure 8 As shown, the shell processing method in this embodiment includes:

[0083] S210, Provide material plates.

[0084] S220. Install a protective layer in non-processing areas.

[0085] The shell processing method in steps S210-S220 of this procedure is exactly the same as the shell processing method involved in steps S110-S120 of the above embodiment, and will not be repeated here.

[0086] S230. Etch the processing area to form an initial uneven structure on the surface of the processing area.

[0087] In this step, such as Figure 4 As shown, the processing area 12 of the material plate 1 is etched to form an initial uneven structure on the surface of the processing area 12, thereby roughening the processing area 12 of the material plate 1.

[0088] In one example, a first etchant is prepared, which can be made from hydrofluoric acid, for example. Hydrofluoric acid etchants of different concentrations are prepared according to the shell requirements and loaded into a spraying device. A material plate 1 with a protective layer is placed on a fixture and conveyed into the spraying device area. Using a linear spraying method, the first etchant is sprayed onto the surface of the processing area 12 for 13-17 seconds, etching the surface of the processing area 12 to form an initial uneven structure. The short spraying time of the hydrofluoric acid etchant allows for rapid formation of the uneven structure, increasing the corrosion rate.

[0089] In another example, a first etching solution is prepared, which may be made of frosting paste. According to the shell requirements, different proportions of frosting paste are prepared to etch a small area of ​​the processing area 12 of the material plate 1 until the surface of the processing area 12 forms an initial uneven structure.

[0090] In another example, a first etching solution is prepared, which can be made from frosting powder, for example. The frosting powder is prepared into a solution according to the shell requirements. The surface of the processing area 12 can be etched by immersion or sandblasting to form an initial uneven structure. When using immersion, the frosting powder and acid are mixed in a certain proportion to form a solution, and the material plate 1 is immersed in the solution for 1.5-3 minutes. When using sandblasting, the frosting powder is loaded into a frosting box, and the material plate 1 is conveyed to a glass support using a conveying device. An acid-resistant pump is used to extract the frosting powder and sandblast the processing area 12 of the material plate 1. The frosting powder is stable in operation, does not easily volatilize in the air, has little impact on air pollution, and can reduce certain hazards during the etching process.

[0091] After corrosion, rinse with clean water to remove the first corrosive liquid, so that the next processing step can proceed without the first corrosive liquid affecting the normal operation of other processes.

[0092] S240, Remove the first preset amount of the initial uneven structure and form a matte layer on the surface of the processing area.

[0093] In this step, such as Figure 4 As shown, the material plate 1 with the initial uneven structure is immersed in the second etching solution for a first preset time, so that the surface of the initial uneven structure is removed by a first preset amount. The initial uneven structure is further etched using the second etching solution to achieve liquid polishing, and finally a matte layer is formed on the surface of the processing area 12.

[0094] The second etching solution can be, for example, a hydrofluoric acid etching solution, which is prepared by mixing M hydrofluoric acid: M water in a ratio of 1.5:7.5, and the first preset time is 8min-10min, the first preset amount of removing the initial uneven structure is 0.03mm-0.04mm, and the flatness of the processing area 12 is improved.

[0095] S250, Remove the protective layer to form the target material plate.

[0096] S260. Process the target material plate to form a shell.

[0097] The shell processing method in steps S250-S260 of this procedure is exactly the same as the shell processing method involved in steps S140-S150 of the above embodiment, and will not be repeated here.

[0098] In this embodiment, the method uses a first etching solution to etch the surface of the processing area into an initial uneven structure, reducing the reflectivity of the processing area, minimizing glare and reflection, and enhancing the premium feel of the casing. A second etching solution with a suitable ratio is then used to further etch the initial uneven structure for a first preset duration to remove a first preset amount, improving the liquid polishing effect, enhancing the flatness of the material plate surface, and improving the feel when holding it.

[0099] In one exemplary embodiment, a housing processing method is provided for processing a housing, such as the housing of an electronic device. Figure 9 As shown, the shell processing method in this embodiment includes:

[0100] S310, Provide material plates.

[0101] S320. Install a protective layer in non-processing areas.

[0102] S330. The material plate with a protective layer is etched to form a matte layer on the surface of the processing area.

[0103] S340, Remove the protective layer to form the target material plate.

[0104] The shell processing method in steps S310-S340 of this step is exactly the same as the shell processing method involved in steps S110-S140 of the above embodiment, and will not be described again here.

[0105] S350, A preset pattern is formed on the target material plate.

[0106] In this step, a preset pattern is formed on the target material plate using laser cutting. This preset pattern can be, for example, the outer contour line of a camera hole or the outer contour line of a housing.

[0107] In one example, such as Figure 5As shown, using laser cutting technology, the corresponding outer contour lines are laser-engraved on the target material plate according to the size and position of the camera hole, etc., with reference to... Figure 5 The notch 2 shown is the outline groove. This laser-engraved surface can be defined as the front side of the target material plate, and the surface corresponding to the front side is the back side.

[0108] Before implementing the laser cutting process, preset laser parameters are set. These preset laser parameters include a laser spot size of φ2μm, a power of 30W, a spot spacing of 3.5μm, and a speed of 40μm / s-50μm / s. This ensures that the laser spots on both the front and back of the target material plate after laser cutting are free from scorching and missing spots, and that the spot spacing is uniform, thereby improving the laser cutting effect.

[0109] After laser cutting, the target material plate is rinsed with running water for about 3 minutes to remove any remaining material residue. After cleaning, the target material plate is placed in an ultrasonic cleaning tank and cleaned for about 2 minutes to remove dirt. It is then removed and air-dried for the next processing step. The ultrasonic frequency is 20Hz.

[0110] S360. The target material plate with the preset pattern is etched to form the initial shell.

[0111] In this step, the target material plate with the preset pattern is etched, and the target material plate is immersed in the fourth etching solution for liquid polishing for a third preset time to remove the second preset amount from the surface of the target material plate and the chamfer preset amount of the outline groove of the preset pattern to form the initial shell.

[0112] The fourth etching solution is a hydrofluoric acid etching solution, prepared by mixing M hydrofluoric acid and M water in a ratio of 1.5:7.5. In this step, the third preset time is 8-10 minutes to ensure that the second preset amount removed from the target material is 0.06mm-0.08mm, achieving the best liquid polishing effect. The contour grooves of the laser-cut pattern are then etched with the fourth etching solution, removing 0.03mm-0.04mm of the chamfer preset amount from the contour of the pattern, further deepening the contour grooves and reducing the connection between the target material in the patterned area and the target material outside the pattern (refer to...). Figure 6 As shown in the figure, this facilitates the completion of subsequent cleaving process steps, ensuring that the cleaving effect can be further improved and the chipping rate reduced during cleaving.

[0113] S370. The initial shell is molded to form the shell.

[0114] In this step, the initial shell is shaped to form the final shell.

[0115] In this embodiment, the etching process of the protective layer and the processing area is performed before the formation of the preset pattern. This avoids ink particles in the protective layer from entering the contour groove of the preset pattern when the protective layer is removed, thereby reducing the occurrence of edge chipping when the shell is broken or cracked and improving the production yield of the shell.

[0116] In one exemplary embodiment, a housing processing method is provided for processing a housing, such as the housing of an electronic device. Figure 10 As shown, the shell processing method in this embodiment includes:

[0117] S410, provides material plates.

[0118] S420. Install a protective layer in non-processing areas.

[0119] S430. The material plate with a protective layer is etched to form a matte layer on the surface of the processing area.

[0120] S440, Remove the protective layer to form the target material plate.

[0121] S450, A preset pattern is formed on the target material plate.

[0122] S460. The target material plate with the preset pattern is etched to form the initial shell.

[0123] The shell processing method in steps S410-S460 of this step is exactly the same as the shell processing method involved in steps S310-S360 of the above embodiment, and will not be described again here.

[0124] S470. The initial shell is placed in a strengthening furnace for strengthening treatment.

[0125] In this step, the initial shell is placed in a strengthening furnace for strengthening treatment to improve the strength of the initial shell and extend its service life.

[0126] Before placing the initial shell in the strengthening furnace for strengthening treatment, it needs to be placed in a preheating furnace at a temperature of 350℃-400℃ for preheating treatment for a fourth preset time, such as 25-35 minutes, to facilitate strengthening. Using a preheating furnace for preheating treatment results in rapid heating and uniform temperature within the furnace, improving the quality of the initial shell and the yield rate.

[0127] The reinforced initial shell is then removed from the reinforcing furnace and placed in an annealing furnace for cooling treatment. The annealing is uniform and the temperature is lowered at a steady rate to further ensure the reinforcing effect.

[0128] S480. Remove part of the initial shell according to the preset pattern to form the shell.

[0129] In this step, the initial shell is placed on a fixture for cleaving. A certain amount of vertical force is applied to the preset pattern in a direction perpendicular to the front surface of the initial shell to complete the cleaving. The magnitude of this vertical force is 0.5MPa-0.7MPa, to avoid damaging the shell if it is too large, and failing to complete the cleaving if it is too small.

[0130] According to a preset pattern, a portion of the initial housing is removed to form the final housing. The removed portion is part of the preset pattern to expose the camera's location and fit the shape of the electronic device's back cover.

[0131] The method in this embodiment utilizes a preheating furnace for preheating, a strengthening furnace for strengthening, and an annealing furnace for cooling. This enhances the strength of the initial shell, provides explosion-proof protection, and further ensures the service life of the initial shell. Even if the initial shell, made of glass, breaks, it will remain glued together without shattering, thus improving the shell's safety.

[0132] The shell processing method proposed in this disclosure utilizes a protective layer to protect the non-processed areas of the material plate, ensuring that only the processed areas are etched, thus achieving a seamless gloss and matte finish. Before laser cutting the preset pattern, the protective layer is removed to prevent particles from entering the contour grooves of the preset pattern, reducing the occurrence of fragmentation and edge chipping during strengthening, improving production yield, and lowering production costs.

[0133] By setting preset laser parameters for the laser cutting process, and using the first and fourth etching solutions, the values ​​of the first and second preset amounts are increased to remove the outer layer of the material plate, achieving a liquid polishing effect, reducing the haze on the surface of the material plate, and improving the smoothness and transmittance of the material plate.

[0134] According to a preset pattern, a portion of the initial shell is removed using vertical force to form the shell. This optimizes the dicing method, satisfying multi-dimensional dicing, and is simple and effective to operate. Furthermore, the chamfer removal amount of the preset pattern is increased to ensure stability during dicing, improve dicing yield, reduce production costs, and shorten the production cycle. Using the shell processing method of this disclosure, the defect rate can be reduced to 2%, making the shell more competitive in the market and providing benefits to manufacturers.

[0135] This disclosure also proposes a housing, which is processed by the housing processing method in any of the above embodiments, so that the housing achieves a matte finish, enhancing the premium feel of the housing and meeting user needs. The housing is a lens structure.

[0136] This disclosure also proposes a camera decorative element, including the housing as described in the above embodiments, and a diaphragm assembly that covers a portion of the housing. The housing is disposed circumferentially along the camera and axially along the camera, thus shielding the camera and providing protection.

[0137] The housing can be a lens structure, which includes a light-transmitting area and a coated area. The light-transmitting area is positioned corresponding to the camera to facilitate image capture. The coated area can surround the light-transmitting area circumferentially, and a diaphragm assembly is disposed within the coated area to enhance the camera's aesthetics. The diaphragm assembly can include one or more of the following: primer, CD texture, and protective film.
