[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Combine the following Figure 1-Figure 13, the casing processing method, casing and electronic device provided by the embodiments of the present invention are described in detail through specific embodiments and their application scenarios.

[0033] First, as Figure 1 , Fig. 9 and Fig.10 As shown, this embodiment provides a casing processing method, comprising the following steps: Step 111 , punching the substrate to obtain a preform, wherein the preform has a bottom wall 1 and four side edges 2 arranged along the circumference of the bottom wall 1 , and a convex bulge 3 is formed on the side of the bottom wall 1 away from the side edge 2 .

[0034] It is understandable that the material of the casing of the electronic device includes metal, plastic or glass, among which the material of the metal parts is mainly aluminum alloy, including 5 series, 6 series, 7 series, and modified aluminum alloy, etc. This embodiment takes aluminum alloy as an example to illustrate the casing processing method.

[0035] The casing processing method of this embodiment can process casings with more complex appearances, such as casings with convex hulls 3 or craters. This embodiment takes a casing with a square-shaped convex hull as an example to describe the specific processing method.

[0036] In order to determine the position of the bulge 3, two positioning holes are provided on the substrate at the bottom wall 1 of the bulge 3. The thickness of the substrate in this embodiment is 1.5 mm. A stamping deformation margin is reserved at the position of the bulge 3. A stamping machine is used to stamp the substrate, and four side edges 2 and the bulge 3 are punched out using different stamping heads.

[0037] Since the punching operation is convenient and the production efficiency is high, the four side edges 2 and the convex bulge 3 of the casing are preliminarily processed by the punching process, which consumes less substrate and has low cost.

[0038] Furthermore, between the stamping process and the extrusion process, the preform needs to be peeled, and a stamping die is used to remove the local material thickness of the preform to correct the thickness of the preform.

[0039] Step 112, the preform is subjected to an extrusion process and a shaping process in sequence.

[0040] It is understandable that when CNC machining the preform, the CNC process needs to reserve a certain machining allowance to facilitate milling. Since the four side edges 2 and the convex bulge 3 are initially shaped by stamping, they are also required to be finely machined by CNC. However, the machining allowance of the four side edges 2 and the convex bulge 3 after stamping cannot meet the requirements of CNC machining. Therefore, the preform after stamping needs to be extruded.

[0041] The preform is extruded using an extrusion die, so that the shell material of the base material is accumulated in the CNC processing area of ​​the preform, and the thickness is increased, which is beneficial to the processing allowance required for milling during subsequent CNC processing. In addition, after the preform is extruded, the preform will be deformed. The preform is shaped using a shaping die to make the appearance of the preform smooth and meet the standards, and the flatness is within 0.6mm, which is convenient for subsequent CNC processing.

[0042] Step 113 , CNC machining is performed on the bottom wall 1 , the four side edges 2 and the convex bulge 3 of the preformed part after the shaping process to obtain a semi-finished casing.

[0043] It is understandable that the preformed part after the shaping process is subjected to CNC processing, the bottom wall 1 is subjected to CNC milling processing, 0.3mm of the processing allowance is removed, and the thickness of the bottom wall 1 is processed from 1.5mm to 1.2mm, and then the four side edges 2 and the convex hull 3 are subjected to CNC milling processing. Since CNC processing adopts a multi-coordinate linkage method, it is convenient to process parts with complex shapes. Through CNC processing, the appearance quality of the product is improved and the refinement is improved.

[0044] Step 114, performing surface treatment on the semi-finished casing to obtain a finished casing.

[0045] It is understandable that after the preform is stamped and CNC processed, the semi-finished casing is surface treated. Through a series of surface treatment operations, the surface hardness of the casing is improved, the durability of the casing is improved, and the appearance of the casing is improved, so that the appearance of the finished casing has beautiful appearance and durability.

[0046] The casing processing method provided by the present invention realizes preliminary stamping of the four side edges 2 and the convex bulge 3 of the casing, and precise CNC processing of the bottom wall 1, the four side edges 2 and the convex bulge 3 by combining stamping processing and CNC processing on the base material, thereby realizing the processing of the casing with a complex appearance. Compared with the method of all CNC processing, the processing method greatly shortens the processing time of the casing and reduces the processing cost of the casing. Compared with the whole stamping processing, the processing method can process complex appearance structures that cannot be achieved by the stamping process, and the preformed parts after stamping are subjected to bulging and shaping processing, which can provide processing allowance for subsequent CNC processing, and achieve the standard of flatness before CNC processing, so that CNC processing can be carried out quickly and conveniently, and the fine processing of the casing with a complex appearance is realized.

[0047] In some embodiments, Figure 2 , Fig. 9 and Fig.10 As shown, in this embodiment, stamping the substrate to obtain a preform includes the following steps: Step 211 , punching the substrate once so that the included angle α between the bottom wall 1 and the side edge 2 of the preform obtained by punching reaches a first angle.

[0048] Step 212, performing a second stamping on the preform that has been stamped once, so that the included angle α between the bottom wall 1 and the side edge 2 of the preform obtained by stamping reaches a second angle.

[0049] The first angle is greater than the second angle.

[0050] It is understandable that the finished product of the housing of the electronic device has a specific angle requirement for the angle α between the bottom wall 1 and the side edge 2, such as Fig. 9 As shown, the angle between the bottom wall 1 and the side 2 of the preform is α, and the preform is a flat plate before one stamping, so the angle α between the bottom wall 1 and the side 2 is 180°, and through the secondary stamping of the substrate, the angle α is stamped to a larger first angle in the first stamping, and the first angle is an obtuse angle, and the angle α is stamped to a smaller second angle in the second stamping, so that the angle α between the bottom wall 1 and the side 2 is successively processed to the second angle through two stampings, and the two stamping processes avoid the stretching angle being too large when the preform is only stamped once to the second angle, resulting in abnormal conditions such as cracks, chrysanthemum marks or shrinkage at the root of the side 2, thereby ensuring the stamping quality of the angle α between the bottom wall 1 and the side 2.

[0051] Specifically, the first angle may be 105° to 115°, and the second angle may be 90°.

[0052] In some embodiments, Figure 3 , Fig. 9 and Fig.10 As shown, in this embodiment, the preform is subjected to the following steps in sequence: Step 311 , the convex hull 3 and four side edges 2 of the preform are subjected to ramming treatment respectively.

[0053] Step 312, shaping the convex hull 3, four side edges 2 and bottom wall 1 of the preform after the extrusion treatment.

[0054] It is understandable that when the preform is subjected to the jacking treatment, the chamfers of the four side edges 2 are firstly extruded into straight edges using the jacking die, and the margin for CNC processing is reserved, and then the jacking die is used to extrude one side of the convex hull 3 and the side edge 2 to extrude the processing margin of the chamfer of the convex hull 3. The jacking treatment can increase the material thickness at the chamfer positions of the convex hull 3 and the four side edges 2, increase the processing margin for CNC processing, and ensure the smooth progress of CNC milling.

[0055] Accordingly, since the shell preform is severely deformed by the extrusion during the piercing process, in addition to the chamfered positions that need to be thickened, other areas will also have unsatisfactory flatness. Therefore, it is necessary to perform shaping treatment on the bulge 3, the four side edges 2 and the bottom wall 1 after the piercing process. First, the bottom wall 1 is shaped, and then, for the outer arch deformation of the bulge 3 and the outer arch deformation of the four side edges 2, a punch head is used to punch from the outside to the inside, and silicone is used for reverse shaping compensation to restore the deformed bulge 3 and the four side edges 2 to flatness. The shaping process can improve the dimensional accuracy and surface quality of the preform to compensate for the shrinkage and deformation of the bulge 3 and the four side edges 2 during the piercing process.

[0056] In some embodiments, Figure 4 , Fig. 9 and Fig.10 As shown, in this embodiment, the bottom wall 1, four side edges 2 and convex bulge 3 of the preformed part after the shaping process are respectively processed by CNC to obtain the semi-finished casing, which includes the following steps: Step 411 , CNC milling is performed on a side surface of the bottom wall 1 facing the side edge 2 to construct at least one characteristic region 6 for arranging functional devices on the surface of the bottom wall 1 .

[0057] Step 412, CNC peeling is performed on the surfaces of the bottom wall 1, four side edges 2 and convex bulge 3 of the preform to obtain a semi-finished casing.

[0058] It is understandable that before processing the side surface of the bottom wall 1 facing the side edge 2, the side of the bottom wall 1 facing away from the side edge 2 is pre-processed first, so that the flatness of the positioning reference surface meets the requirements and the internal stress is released.

[0059] Secondly, a CNC milling process is performed on a side of the bottom wall 1 facing the side edge 2 using a round wall cutter to form a characteristic area 6 for arranging functional devices. The characteristic area 6 may be one or more.

[0060] Specifically, the characteristic area 6 may be a first speaker avoidance area 61 , a mainboard component avoidance area 62 , a second speaker avoidance area 63 , or a mainboard avoidance area 64 .

[0061] Furthermore, a flip module avoidance area 65 , a rear camera opening 66 and a rear flash window 67 are provided on the convex bump 3 .

[0062] Next, the bottom wall 1 of the preform is peeled with a disc knife to remove 0.3 mm of process margin, so that the wall thickness after peeling reaches 1.2 mm, and the surfaces of the four side edges 2 and the convex bulge 3 also meet the requirements.

[0063] The CNC processing of this embodiment can not only process the characteristic area 6 on the inner side of the bottom wall 1, but also perform peeling processing on the surface of the bottom wall 1, the four side edges 2 and the convex bulge 3. A complex structure can be constructed through CNC processing with high processing accuracy.

[0064] In some embodiments, Figure 5 , Fig. 9 and Fig.10 As shown, in this embodiment, the CNC peeling process of the bottom wall 1, the four side edges 2 and the convex bulge 3 of the preform includes the following steps: Step 511 , CNC milling is performed on the surfaces of the bottom wall 1 , the four side edges 2 and the convex hull 3 .

[0065] Step 512 , performing CNC milling processing on the chamfered areas corresponding to the four side edges 2 and the chamfered area corresponding to the convex hull 3 .

[0066] Step 513 , grinding the chamfered areas corresponding to the four side edges 2 and the chamfered areas corresponding to the convex hull 3 respectively.

[0067] It can be understood that, first, the surfaces of the bottom wall 1, the four side edges 2 and the bulge 3 are processed by CNC milling. The bottom wall 1 is processed by a disc cutter, the four side edges 2 are processed by an R-angle cutter, and the bulge 3 is processed by a forming cutter. Appropriate tools are selected according to the specific contours of the surfaces to be processed, so that the surface processing allowance can be removed more accurately, thereby ensuring the surface processing quality.

[0068] Secondly, since the convex hull 3 will have problems such as collapsed edge, cracks and deformation after stamping, a forming cutter is used to mill the chamfer position of the convex hull 3. Since the radius of the chamfer of the four side edges 2 is 1mm and the base material is 1.5mm, the thickness of the chamfer position of the side edge 2 is increased by extrusion after stamping, and the CNC processing allowance is reserved, and then the R angle cutter is used to mill the chamfer with a radius of 1mm. The processing of the convex hull 3 uses a forming cutter, which can smoothly transition with the bottom wall 1, ensuring the quality of the chamfer.

[0069] Since the chamfering position of the convex hull 3 is processed with a forming knife, and the chamfering positions of the four side edges 2 are processed with an R-angle knife, there are knife marks at the junction of the two knives, and the junction area needs to be polished to eliminate the knife marks. The specific location of the knife marks is the intersection of the convex hull 3 and the bottom wall 1 and the sharp point of the intersection of the convex hull 3 and the side edge 2. By polishing the docking knife marks, the surface flatness of the chamfered area meets the requirements, ensuring the processing quality of the chamfered position.

[0070] In some embodiments, Figure 6 , Fig.11 , Fig.12 and Fig.13As shown, the present embodiment further includes the following steps between the extrusion process and the shaping process of the preform: Step 611 , punching the side edge 2 of the preform to punch out a first structure 4 on the side edge 2 .

[0071] The present embodiment further includes the following steps between CNC machining and surface treatment of the preform: In step 612 , CNC machining is performed on the side edge 2 of the preform to form a second structure 5 on the side edge 2 .

[0072] It is understandable that a series of structural structures need to be processed on the surface of the housing to facilitate the connection between the electronic device and peripheral devices, and to facilitate the realization of the functions of the electronic device.

[0073] When the functional requirements and precision requirements of the structural structure are not high, and the shape and size are relatively simple, stamping can be used for manufacturing. Stamping can process structural structures in large quantities with high consistency and low cost. Correspondingly, when the design of the structural structure is more complex and the precision requirements are higher, CNC processing can be used for manufacturing. CNC processing can provide higher processing precision and flexibility, so that the structural structure meets personalized design requirements.

[0074] Optionally, the first structure 4 can be a speaker hole 41, the shape and size of the speaker hole 41 are relatively simple, and the speaker hole 41 is evenly distributed on the casing, so the speaker hole 41 is manufactured by a stamping process; the second structure 5 can be a TYPE-C hole 51, a button hole 52 or a microphone hole 53, the manufacturing precision requirements of the TYPE-C hole 51, the button hole 52 or the microphone hole 53 are relatively high, and the shapes and sizes of the holes are also different, so the TYPE-C hole 51, the button hole 52 or the microphone hole 53 are CNC processed.

[0075] In some embodiments, Figure 1 and Figure 7 As shown, this embodiment further includes the following steps before stamping the substrate: Step 711, applying a protective film to the surface of the substrate.

[0076] The present embodiment further includes the following steps between CNC machining and surface treatment of the preform: Step 712, performing film-tearing treatment on the surface of the preform.

[0077] It is understandable that before stamping and CNC processing the substrate, a protective film is first applied to the surface of the substrate, and the protective film can prevent the substrate from being scratched and dented during processing, thereby avoiding damage to the substrate. Furthermore, when the preform is CNC processed and surface treatment is required to obtain a finished product, the applied protective film needs to be removed to expose the surface of the housing for easy surface treatment.

[0078] Specifically, the protective film may be a laser engraved protective film.

[0079] In some embodiments, Figure 1 and Figure 8 As shown, the surface treatment of the semi-finished casing in this embodiment includes the following steps: Step 811, cleaning the surface of the semi-finished casing.

[0080] Step 812, polishing the surface of the cleaned semi-finished casing.

[0081] Step 813, sandblasting the surface of the semi-finished casing after the grinding process.

[0082] Step 814, anodizing the surface of the semi-finished casing after sandblasting.

[0083] Step 815, performing laser engraving on the surface of the semi-finished casing after anodizing treatment to obtain a finished casing.

[0084] It is understandable that, first, the semi-finished casing is soaked, scrubbed and rinsed with a cleaning agent, and the semi-finished casing is dried to complete the cleaning process of the semi-finished casing.

[0085] Secondly, the semi-finished housing with a clean surface is polished using sandpaper, a polishing pad or an electric grinder, and dust is removed. The sharp corners of the bottom wall 1 and the convex bulge 3 of the semi-finished housing are polished, especially the contact position between the convex bulge 3 and the bottom wall 1 needs to be polished to remove deformation and obvious marks.

[0086] Next, the surface of the semi-finished housing after grinding is sandblasted, and a suitable sandblasting medium is selected, and the sandblasting medium is sprayed onto the surface of the semi-finished housing using a spray gun, and residues and dust are cleaned. Specifically, both sides of the bottom wall 1 of the semi-finished housing need to be sandblasted.

[0087] Then, the semi-finished casing after sandblasting is anodized to form an oxide film on the surface of the semi-finished casing.

[0088] Finally, the semi-finished case after anodization is laser engraved, and the surface of the semi-finished case is precisely processed by laser to achieve high-precision logo engraving on the surface of the semi-finished case, thereby obtaining a finished case. Specifically, this embodiment is used to laser engrave the conductive grounding and back adhesive bonding areas.

[0089] Second, as Figure 1 As shown, this embodiment provides a casing, which is prepared by the above casing processing method.

[0090] It can be understood that the casing of this embodiment can be suitable for a learning machine. The casing has four sides and one of the sides is equipped with a display screen. A accommodating cavity is formed between the display screen and the casing. The mainboard components, batteries, speakers, front camera, front flash and other functional components are installed in the accommodating cavity. The flip module, rear camera and rear flash are installed in the convex bulge.

[0091] The housing of this embodiment adopts a combination of stamping and CNC processing, so that the housing can present a complex appearance, and the processing time of the housing is shortened and the cost is reduced. The housing of this embodiment can meet the requirements of complex and fine appearance, and the processing cost of the housing is controlled.

[0092] In a third aspect, this embodiment provides an electronic device, including the above casing.

[0093] It is understandable that an electronic device has a casing. Since the casing of this embodiment has a complex appearance structure, it has a wide range of applications and can be used in casings of various electronic devices.

[0094] Specifically, the electronic device may be a tablet computer, a learning machine, a handheld device, a mobile phone or a voice recorder.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
