[0036] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The present invention proposes a method for manufacturing a terminal device structural component, which can reduce the manufacturing cost of the structural component, form an integrated structure with multiple layers of materials as needed, facilitate the use of the structural component to manufacture the terminal device, improve the manufacturing efficiency, and make the interface between the multiple layers of materials have a higher connection strength, thereby improving the production stability. A computer-readable storage medium, a manufacturing device for the terminal device structural component, and a terminal device are also proposed.

[0038] like Figure 1 As shown, according to a method for manufacturing a terminal device structural component according to a first aspect of the present invention, the manufacturing method includes:

[0039] Step S100, manufacturing an integrated structure including multiple layers of materials by a friction stir additive process, wherein the multiple layers of materials are vertically distributed along the axial direction.

[0040] Specifically, the controller or the operator can control the additive spindle head in the additive module to perform stir friction additive on the outer peripheral surface of the substrate. During this process, the additive spindle head moves along the outer peripheral surface of the substrate and maintains stirring friction. The friction heat generated by the friction between the additive material and the substrate and the plastic deformation caused by the violent deformation of the material form a visco-plastic deposition layer, and as the deposition layer is vertically accumulated along the axial direction of the substrate, an integrated structure including multiple layers of material is formed, that is, the multiple layers of material include a substrate and an additive layer. In this way, an integrated structure including multiple layers of material is produced by the stir friction additive process, which can reduce the manufacturing cost of structural parts and improve manufacturing efficiency. The interface between the multiple layers of material has a high connection strength, thereby improving production stability.

[0041] In addition, according to the needs of the terminal equipment, the same or different types of materials can be deposited on the substrate. For example, a 7-series aluminum alloy with good strength can be deposited on the substrate to form an integrated structure with a double-layer material of a substrate of a 6-series aluminum alloy and an additive layer of a 7-series aluminum alloy. For another example, a 6-series aluminum alloy with good corrosion resistance and welding performance can be deposited on the substrate to form an integrated structure with a double-layer material of a substrate of a 7-series aluminum alloy or titanium and an additive layer of a 6-series aluminum alloy.

[0042] Step S200, blanking the integrated structure along a preset blanking plane to obtain a structural component, wherein the preset blanking plane is vertically parallel to the axial direction.

[0043] Specifically, according to the size requirements of the structural parts, the controller or the operator controls the blanking module to perform blanking processing on the integrated structure along the preset blanking plane, so that a structural part of a predetermined size can be obtained, and the preset blanking plane is vertically parallel to the axis direction of the substrate, so that the structural part obtained by blanking includes multiple layers of materials in the integrated structure, so as to obtain a structural part with predetermined performance. In addition, the blanking process can be a cutting process, that is, the integrated structure is cut to obtain the structural part.

[0044] In addition, in some specific examples, the terminal device may be a mobile phone, and the structural parts may, after subsequent processing, form an integrated mobile phone shell structure including a border frame and a middle plate or a separate middle plate structure, that is, the additive layer or the additive layer and a part of the substrate form a frame, and the substrate or other parts of the substrate form the middle plate; or only form the middle plate, that is, the substrate forms the middle part of the middle plate, and the additive layer forms the edge part of the middle plate; wherein the frame is located at the edge part of the mobile phone to protect the mobile phone from impact and corrosion, and the middle plate is located in the middle of the mobile phone and can be used as a support plate to provide support and installation points for the functional components of the mobile phone.

[0045] It should be noted that blanking can be understood as the process of removing materials of a certain shape, quantity or quality from the entire material or a batch of materials after determining the shape, quantity or quality of the materials required to make a certain device or product.

[0046] In summary, according to the manufacturing method of terminal equipment structural parts in an embodiment of the present invention, an integrated structure including multiple layers of materials is produced through a stir friction additive process, and then the integrated structure is blanked to obtain structural parts, which is convenient for using the structural parts to manufacture terminal equipment, can reduce the manufacturing cost of the structural parts, improve manufacturing efficiency, and make the interfaces between the multiple layers of materials have a higher connection strength, thereby improving production stability.

[0047] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the one-piece structure includes a substrate and an additive layer, and the substrate is integrally formed or separately formed; in some examples, the one-piece formed substrate: the additive layer is deposited on the outer peripheral surface of the substrate by a stir friction additive process, and then the material is cut to obtain a structural part including the substrate and the additive layer, which can help improve the deposition efficiency, reduce the waste of deposition materials, and the deposition quality is more stable. In other examples, the separately formed substrate: the substrate includes multiple separate parts, and the additive layer is deposited on the outer peripheral surface of the substrate by a stir friction additive process, and then only the additive layer can be cut to obtain a structural part including the substrate and the additive layer, thereby improving production efficiency.

[0048] like Figure 2 As shown, in some embodiments of the present invention, if the substrate is formed in separate parts, before the step S100 of manufacturing an integrated structure including multiple layers of materials by a friction stir additive process, the manufacturing method further includes:

[0049] Step S100 ′, determining that the separately formed substrate is in an aligned state, and then clamping the separately formed substrate along the axis direction.

[0050] Specifically, an operator stacks the split-structure substrate neatly so that the peripheral surfaces of the multiple split parts of the substrate are flush, and then the operator or the controller controls the clamping module to clamp the split-structure substrate along the axial direction so that the peripheral surfaces of the multiple split parts of the substrate are flush and tightly fitted together. Through the aforementioned steps, when adding material to the peripheral surface of the split substrate, the uniformity of the additive layer can be improved, avoiding the problems of uneven peripheral surface of the split-structure substrate, resulting in material waste, poor additive effect, etc.

[0051] like Figure 3 As shown, in some embodiments of the present invention, the shape of the substrate is columnar, and the step S100 of manufacturing an integrated structure including multiple layers of materials by a friction stir additive process includes:

[0052] Step S110 , performing spiral additive processing or reciprocating additive processing on the circumference of the substrate along the axial direction, so that the additive layer evenly covers the circumference of the substrate.

[0053] According to the first example, when making an integrated structure of multi-layer materials, the operator or controller can control the additive spindle head of the additive module, and the additive spindle head makes a spiral motion along the outer circumference of the substrate with the axis of the substrate as the reference, so as to deposit an additive layer on the outer circumference of the substrate; According to the second example, when making an integrated structure of multi-layer materials, the operator or controller can control the additive spindle head of the additive module, and the additive spindle head moves from one end of the substrate to the other end of the substrate along the axial direction on the outer circumference of the substrate, and moves along the circumference of the substrate (i.e., along the direction around the axis), then moves from the other end of the substrate to one end of the substrate along the axial direction, and moves along the circumference of the substrate (i.e., along the direction around the axis), and then continuously repeats the above steps to make a reciprocating motion on the outer circumference of the substrate, so as to deposit an additive layer on the outer circumference of the substrate; in this way, the additive layer can evenly cover the outer circumference of the substrate, and the efficiency of the additive can be improved, thereby improving the production efficiency of the structural parts.

[0054] Of course, if Figure 4 and Figure 8 The rotation and displacement of the substrate can also be controlled by a positioner and other equipment, while the spindle head remains stationary, thereby achieving spiral additive or reciprocating additive.

[0055] like Figure 3 As shown, in some embodiments of the present invention, step S100 of manufacturing an integrated structure including multiple layers of materials by a friction stir additive process includes:

[0056] Step S120, depositing an additive layer on the substrate along a direction around the axis using a friction stir additive process, wherein the direction around the axis has an angle less than 90° with a preset blanking plane.

[0057] Specifically, the controller or operator can control the additive spindle head of the additive module to deposit the additive layer on the outer peripheral surface of the substrate along the direction around the axis. After the additive is completed, the unloading module can be controlled to unload the integrated structure along the preset unloading plane, and the extension direction of the additive layer on the obtained structural part has an angle of less than 90° with the direction around the axis. The additive layer of such a structural part is more uniform, which can reduce the occurrence of cracking and improve production stability. Preferably, the preset unloading plane is arranged parallel to the direction around the axis, that is, the angle between the extension direction of the additive layer on the structural part and the direction around the axis is 0°, so as to further improve the uniformity of the additive layer.

[0058] like Figure 7As shown, in some embodiments of the present invention, the outer peripheral surface of the substrate is provided with at least one groove and / or at least one protrusion; in this way, the surface area of ​​the substrate can be increased to increase the connection area between the substrate and the additive layer, so that the additive layer and the substrate can be tightly combined; in addition, since the embodiment of the present invention adopts a stir friction additive process to manufacture an integrated structure, the grooves and protrusions can increase the roughness of the outer peripheral surface of the substrate, so that the additive material on the additive spindle head can more easily generate friction and deposit on the substrate.

[0059] Figure 7 Cross-sections of various integrated structures are shown, which include substrates of various shapes and additive layers of various shapes.

[0060] like Figure 1 and Fig.10 As shown, in some embodiments of the present invention, after step S200 of blanking the integrated structure along a preset blanking plane, the manufacturing method further includes:

[0061] Step S300 , forming the structural part to be processed after the blanking process according to the size requirements of the structural part to obtain the structural part.

[0062] Specifically, in combination with the foregoing, the substrate may be a columnar structure, and the integrated structure formed by the substrate after material addition is also a columnar structure, and the integrated structure is blanked to obtain the structural part to be processed; wherein, the substrate may be a cylindrical structure or a prismatic structure; according to the size requirements of the structural part, the operator or the controller may control the forming module, and the forming module may include a forging machine, through which the structural part to be processed is forged and processed to obtain a structural part of a predetermined size, thereby meeting the production requirements of the terminal equipment.

[0063] like Figure 5 , Figure 6 and Fig. 9 As shown, in some embodiments of the present invention, the hardness of the material corresponding to the substrate is greater than the hardness of the material corresponding to the additive layer; it can be understood that the terminal device can be a mobile phone, the substrate of the structural member forms the middle plate of the mobile phone, and the additive layer of the structural member forms the frame of the mobile phone. The middle plate of the mobile phone needs to be installed with more functional devices. In order to ensure the stable operation of the mobile phone, the middle plate of the mobile phone needs to have a stronger hardness. Therefore, the hardness of the material corresponding to the substrate can be made greater than the hardness of the material corresponding to the additive layer to meet the use requirements of the mobile phone.

[0064] In other embodiments of the present invention, the corrosion resistance of the material corresponding to the substrate is lower than that of the material corresponding to the additive layer. It is understandable that the mobile phone frame is generally exposed on the outer surface of the mobile phone. In daily use, the external environment will corrode the mobile phone frame. At this time, in order to improve the corrosion resistance of the mobile phone, the corrosion resistance of the material corresponding to the substrate can be made lower than that of the material corresponding to the additive layer, so that the corrosion resistance of the frame is stronger than that of the middle plate.

[0065] In some further embodiments of the present invention, the welding performance of the material corresponding to the additive layer is better than the welding performance of the material corresponding to the base material; it can be understood that the base material of the structural component can form the middle part of the mobile phone middle plate, and the additive layer of the structural component can form the edge part of the mobile phone middle plate. In order to facilitate the welding of the mobile phone middle plate and the frame, the welding performance of the material corresponding to the base material layer can be better than the welding performance of the material corresponding to the base material, thereby improving the welding strength between the mobile phone middle plate and the mobile phone frame.

[0066] Among them, the material corresponding to the substrate can be 7 series aluminum alloy or titanium, and the material corresponding to the additive layer can be 6 series aluminum alloy.

[0067] like Figure 1 As shown, in some embodiments of the present invention, the manufacturing method further includes:

[0068] Step S400, processing the outer surface of the structural component by CNC process and DDG process respectively to determine the structural shape of the structural component, the structural component includes a middle plate, or an integrally formed middle plate and frame.

[0069] Specifically, the operator or controller can control the CNC machine tool to perform CNC processing (i.e., computer numerical control (Computer Numerical Control) processing) on ​​the outer surface of the structural part, and perform rough processing on the outer surface of the structural part, thereby removing burrs on the outer surface of the structural part; in addition, the DDG process refers to the processing method of a fully CNC high-efficiency double-end surface precision grinder (CNC double side surface grinder). By performing DDG process grinding on the outer surface of the structural part, the surface of the structural part, especially the upper and lower bottom surfaces, can be ground and polished to obtain a smoother and more uniform structural part. Furthermore, according to the size requirements of the terminal device, the structural part is finely processed by the CNC process, so as to determine the structural shape of the structural part. In this way, the processing of the structural parts by the aforementioned CNC process and DDG process can facilitate the subsequent manufacture of the terminal equipment and improve convenience and surface performance.

[0070] Furthermore, the structural parts can be finely processed through CNC processes and DDG processes, so that the structural parts form a middle plate, or form an integrally formed middle plate and frame to meet the manufacturing requirements of the terminal equipment.

[0071] like Figure 5 , Figure 6 and Fig. 9 As shown, in some embodiments of the present invention, the multilayer material includes at least two of different series of aluminum alloys, titanium, steel, magnesium and copper. Optionally, the material of the substrate can be 7-series aluminum alloy, and the material of the additive layer can be 6-series aluminum alloy, or the material of the substrate can be titanium, and the material of the additive layer can be 6-series aluminum alloy. In this way, the substrate has a higher structural strength, thereby improving the structural strength of the terminal device structural parts, and the additive layer has good corrosion resistance, thereby improving the corrosion resistance of the terminal device structural parts; in addition, when the structural parts are used to make a middle plate, the additive layer is a 6-series aluminum alloy, so that in the subsequent welding process of the middle plate and the mobile phone frame, the middle plate can have better welding performance.

[0072] Based on the manufacturing method of the terminal device structural component of the aforementioned embodiment, a computer-readable storage medium according to an embodiment of the second aspect of the present invention stores a manufacturing program of the terminal device structural component, and when the manufacturing program is executed by the processor, the manufacturing method of the terminal device structural component mentioned above is implemented.

[0073] According to the computer-readable storage medium of the embodiment of the present invention, by executing the manufacturing program of the terminal device structural parts through the processor, an integrated structure with multi-layer materials can be formed as needed, which is convenient for using the structural parts to manufacture terminal devices, can reduce the manufacturing cost of the structural parts, improve manufacturing efficiency, and make the interface between the multi-layer materials have a higher connection strength, thereby improving production stability.

[0074] According to the manufacturing device of the terminal equipment structural component of the third aspect embodiment of the present invention, the manufacturing device includes an additive module and a blanking module.

[0075] Among them, the additive module is used to produce an integrated structure including multiple layers of materials through a stir friction additive process, and the multiple layers of materials are distributed vertically along the axial direction; the blanking module is used to blank the integrated structure along a preset blanking plane to obtain a structural part, wherein the preset blanking plane is vertically parallel to the axial direction; in this way, the manufacturing cost of the structural parts can be reduced, the manufacturing efficiency can be improved, and the interface between the multiple layers of materials has a higher connection strength, thereby improving production stability.

[0076] Specifically, in the process of manufacturing terminal equipment structural parts, first, the controller can control the additive spindle head of the additive module to move and stir friction on the outer peripheral surface of the substrate, so that the additive material can be deposited on the outer peripheral surface of the substrate to form an integrated structure including the substrate and the additive layer, wherein the material of the substrate can be 7 series aluminum alloy or titanium to provide good structural strength for the terminal equipment structural parts, and the material of the additive layer can be 6 series aluminum alloy to improve the corrosion resistance of the terminal equipment structural parts; in addition, when the structural parts are used to make the middle plate, the additive layer is 6 series aluminum alloy, so that in the subsequent welding process of the middle plate and the mobile phone frame, the middle plate can have better welding performance. And spiral additive and reciprocating additive methods can be used to improve the uniformity of the additive layer and the additive efficiency.

[0077] Then, the controller can control the blanking module to cut the integrated structure along a preset blanking plane to obtain a structural part, wherein the preset blanking plane is vertically parallel to the axial direction and has an angle less than 90° with the moving direction of the additive spindle head, so that the uniformity of the additive layer in the obtained structural part is higher; preferably, the angle between the preset blanking plane and the moving direction of the additive spindle head is 0°, so as to further improve the uniformity of the additive layer in the structural part.

[0078] The manufacturing device also includes a forming module, which is used to form the structural parts to be processed after the blanking process; after the above steps, the controller can control the forming module to perform forging and other processes on the structural parts to be processed to obtain structural parts of predetermined size and shape.

[0079] The aforementioned steps are applicable to an integrated substrate. If the substrate includes multiple separate parts, the manufacturing device also includes a clamping module, which is used to clamp the separate structure substrate along the axial direction. Before the additive step, the operator needs to align the multiple separate parts of the substrate, and the controller controls the clamping module to clamp the multiple separate parts of the substrate along the axial direction, so as to facilitate subsequent additive operations and improve convenience.

[0080] Finally, the controller can control the CNC machine tool to perform CNC process and DDG process grinding on the outer surface of the structural part to obtain the structural part with a predetermined shape.

[0081] In summary, an integrated structure including multiple layers of materials is produced by controlling the additive module, and then the blanking module is controlled to perform blanking on the integrated structure to obtain structural parts, which makes it convenient to use the structural parts to make terminal equipment, reduces the manufacturing cost of the structural parts, improves manufacturing efficiency, and makes the interfaces between the multiple layers of materials have higher connection strength, thereby improving production stability.

[0082] It should be noted that the additive module may include an additive spindle head and a positioner. The additive spindle head is used to stir and frictionally add material on the outer peripheral surface of the substrate, and the positioner is used to control the rotation and displacement of the substrate relative to the additive spindle head. The blanking module may include a cutting machine. The forming module may include a forging press, which is used to forge and form the structural parts to be processed according to predetermined size requirements. The clamping module may include a clamp, which is used to clamp the substrate.

[0083] According to the terminal device of the fourth aspect of the embodiment of the present invention, the terminal device includes structural parts, and the structural parts are manufactured according to the manufacturing method of the terminal device structural parts in the above-mentioned embodiment. By using the aforementioned structural parts to manufacture the terminal device, the manufacturing cost of the structural parts can be reduced, and the structural strength, performance and production efficiency of the terminal device can be improved.

[0084] Terminal devices can be mobile phones, tablets, laptops, etc.

[0085] It should be noted that other specific implementations of the terminal device proposed in the embodiment of the present invention can refer to the specific implementation of the method for manufacturing the terminal device structural component in the aforementioned embodiment of the present invention, and will not be repeated here to reduce redundancy.

[0086] It needs to be explained that the friction stir additive manufacturing (FSAM) process is a solid-phase additive manufacturing technology that uses metal rods, powders, and wires as additive materials. During the additive process, the friction heat generated by the friction between the additive material and the substrate and the plastic deformation heat generated by the violent deformation of the material are used to form a viscoplastic deposition layer. The deposition layers are accumulated layer by layer to form an integrated structure.

[0087] It should be explained that the friction stir welding process refers to the use of the heat generated by the friction between the high-speed rotating welding tool and the workpiece to locally soften the material to be welded. When the welding tool moves forward along the welding interface, the plasticized material flows from the front to the back of the welding tool under the action of the rotating friction force of the welding tool, and forms a dense solid phase weld under the extrusion of the welding tool.

[0088] like Figure 5 and Figure 6 As shown, in some specific examples of the present invention, the method for manufacturing a terminal device structural component includes:

[0089] The first step is friction stir additive manufacturing: depositing 6 series aluminum on 7 series aluminum.

[0090] 7 series aluminum is a cuboid or a plurality of rectangular sheets assembled into a cuboid by means of tooling clamping, etc., and its surface processing such as grooves and other structures that facilitate material deposition (i.e., protrusions and / or grooves). The cross-section of 7 series aluminum can be rectangular, and the four corners of the rectangle can be right angles, rounded corners, or chamfered. When depositing 6 series aluminum on the surface of 7 series aluminum, different surfaces can be flipped in steps manually or by automatic methods such as positioners, and deposition is completed on the four cylinders on the side and the corners where the cylinders connect.

[0091] The second step is to cut the deposited material into sheets of specified width: cutting methods such as saw blade cutting, laser cutting, water cutting or wire cutting can be used.

[0092] The third step is grinding and polishing and CNC process: for the cut sheet, the CNC is performed after grinding and polishing, or CNC is performed directly without grinding and polishing, to remove the surface arc lines and interlayer features of the 6-series aluminum of the stir friction additive, and to process the deposited 6-series aluminum and 7-series aluminum into a specified shape. Finally, the semi-finished blank of the aluminum mobile phone frame + middle plate or a separate middle plate semi-finished product is formed.

[0093] The fourth step is finishing: further finishing a unique structure on the semi-finished blank to form the final mobile phone frame & middle plate structure or a separate middle plate structure.

[0094] like Fig. 9 As shown, in another specific example of the present invention, a method for manufacturing a terminal device structural component includes:

[0095] Step 1: Friction stir additive. Deposit 6 series aluminum on 7 series aluminum. 7 series aluminum is a cylinder. There are two ways to deposit 6 series aluminum on the surface of 7 series aluminum;

[0096] Method 1: The 7-series aluminum and the additive spindle head rotate relative to each other while moving relative to the axial direction of the cylinder. The additive spindle head moves in a spiral motion relative to the cylinder to uniformly deposit the 6-series aluminum alloy on the cylinder.

[0097] Method 2: The 7 series aluminum cylinder remains stationary, and the additive head moves laterally along the side generatrix of the cylinder. When it reaches the end of the cylinder, the cylinder rotates a certain angle, the additive head reaches the new position, and then moves back laterally along the side generatrix, and so on, to achieve deposition on the entire side of the cylinder.

[0098] The second step is to cut the deposited material into sheets of specified width: cutting methods such as saw blade cutting, laser cutting, water cutting or wire cutting can be used.

[0099] The third step is forming: the circular sheet is formed into a rectangle by forging or other methods.

[0100] Step 4: Grinding and polishing and CNC process: For the rectangular sheet after forming, the CNC process is carried out after grinding and polishing, or the CNC process is carried out directly without grinding and polishing, to remove the surface arc lines and interlayer features of the material 2 of the stir friction additive, and to process the deposited material 2 and the material 1 body into a specified shape. Finally, the semi-finished blank of the aluminum mobile phone frame + middle plate or a separate middle plate semi-finished product is formed.

[0101] Step 5: Finishing: Further finishing the semi-finished blank to produce a unique structure to form the final mobile phone frame & middle plate structure or a separate middle plate structure.

[0102] The 7-series aluminum alloy frame and middle plate in the related technology are usually directly processed by CNC on the 7-series aluminum plate to form the frame, middle plate and the structure above. However, the 7-series aluminum alloy has a low corrosion resistance, which limits its direct application in mobile phones. The corrosion resistance of 6-series aluminum is better than that of 7-series aluminum, and can meet the requirements of surface treatment such as corrosion resistance on mobile phones. The method of depositing 6-series aluminum alloy on 7-series aluminum can be electroplating or meteorological deposition, but the thickness is limited, generally only a few tens of microns at most; if a 6-series aluminum alloy deposition layer with a thickness of millimeters is required, cold spraying can be used, but the density of the deposition layer is low and the efficiency is low.

[0103] In addition, the welding performance of 7 series aluminum is poor. When 7 series aluminum is used as the middle plate, it is difficult to weld it to the frame (mostly made of aluminum or titanium) and the yield is low. Because the welding performance of 6 series aluminum is better, a certain thickness of 6 series aluminum alloy is wrapped around the periphery of the 7 series aluminum to form a 7 series / 6 series middle plate. The 6 series aluminum on the periphery of the middle plate is then connected to the frame, which can improve the welding yield and stability.

[0104] Therefore, the present invention proposes a method for manufacturing terminal device structural parts, which can form an integrated structure with multiple layers of materials as needed, facilitate the use of structural parts to manufacture terminal devices, improve manufacturing efficiency, and make the interface between the multiple layers of materials have a higher connection strength, thereby improving production stability; and can meet the thickness requirements of specific materials.
