[0039] 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.

[0040] The present invention proposes a method for manufacturing a terminal device structural component, which can reduce the manufacturing cost of the structural component, is not limited by the mold, forms an integrated structure of multi-layer materials as required, and makes the interface between the multi-layer materials have a high connection strength, thereby improving production stability; and can produce a structural sub-component including at least a part of the frame and at least a part of the middle plate as required, and make the structural sub-component form a structural component, thereby improving production efficiency. A computer-readable storage medium, a manufacturing device for a terminal device structural component, and a terminal device are also proposed.

[0041] like Figures 1 to 6 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:

[0042] Step S100, manufacturing an integrated structure including multiple layers of materials by a friction stir additive process, wherein the multiple layers of materials are distributed along a thickness direction BB, wherein the integrated structure includes a first material layer and a second material layer, the second material layer includes a first portion, and the first portion is protruding relative to the first material layer.

[0043] Specifically, the controller or the operator can control the additive spindle head in the additive module to perform stir friction on a layer of substrate. In this process, a visco-plastic deposition layer is formed by 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. The deposition layer is accumulated along the thickness direction of the substrate to form an integrated structure including multiple layers of material. It can be understood that compared with the related art of producing an integrated structure including multiple layers of material through a hot rolling process, the embodiment of the present invention uses a stir friction additive process, which has high material utilization, simple process, high yield, no need for a large manufacturing device, and is not restricted by molds, etc., and the interface between the multiple layers of material has a high connection strength, thereby improving production stability.

[0044] In addition, the integrated structure includes a first material layer and a second material layer, wherein the first material layer may be a substrate, the second material layer may be formed of an additive material, and through a stir friction additive process, the first portion of the second material layer is raised relative to the first material layer; specifically, the first material layer has a first surface close to the second material layer, and the second material layer has a second surface away from the second material layer, and the second surface is raised relative to the first surface in the thickness direction and away from the first material layer. In this way, the first portion of the second material layer can replace at least a portion of the middle plate when the structural component is formed, and the first material layer can replace at least a portion of the frame when the structural component is formed, thereby improving the production efficiency of the terminal device structural components.

[0045] 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, titanium or 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 6-series aluminum alloy and an additive layer of titanium or 7-series aluminum alloy. For another example, a 6-series aluminum alloy with good welding performance can be deposited on the substrate to form an integrated structure with a double-layer material of a substrate of 7-series aluminum alloy or titanium and an additive layer of 6-series aluminum alloy.

[0046] Step S200, blanking the integrated structure along a preset blanking plane to obtain at least one structural sub-component, wherein the preset blanking plane is parallel to the thickness direction.

[0047] 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 at least one structural sub-component can be obtained, and the preset blanking plane is parallel to the thickness direction, so that at least one structural sub-component can include multiple layers of materials in the integrated structure, so as to obtain at least one structural sub-component with predetermined performance. Among them, the structural sub-component includes at least a part of the frame and at least a part of the middle plate, at least a part of the frame is obtained by blanking the first material layer, and at least a part of the middle plate is obtained by blanking the first part of the second material layer. In addition, the blanking process can be a cutting process, that is, the integrated structure is cut to obtain at least one structural sub-component.

[0048] 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.

[0049] Step S300: connecting at least one structural sub-component to form a structural component.

[0050] Specifically, the number of structural sub-components can be one, three, or five; in some examples, when there is one structural sub-component, the controller or operator controls the bending module, which first bends the frame so that the frame fits along the edge shape of the middle plate, and then the controller controls the connection module to connect the frame to the periphery of the middle plate to form a structural component of the terminal device. In other examples, when there are two structural sub-components, the controller or operator controls the connection module, which first assembles the two structural sub-components accordingly, that is, the middle plate parts of the two structural sub-components are assembled into the middle plate, and the frame parts of the two structural sub-components are assembled into the frame, and then the structural sub-components are connected to form a structural component of the terminal device.

[0051] For ease of understanding, unless otherwise specified, the following description will be made by taking the example that at least one structural sub-component includes two.

[0052] In addition, in some specific examples, the terminal device can be a mobile phone, and the two structural sub-components can form an integrated structural component including a mobile phone frame and a mobile phone middle plate. The frame is located at the edge of the mobile phone to protect the mobile phone from impact. The middle plate is located inside 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.

[0053] Therefore, according to the manufacturing method of terminal equipment structural parts of the embodiment of the present invention, an integrated structure of multi-layer materials is manufactured through a stir friction additive process, and then the integrated structure is blanked to obtain at least one structural sub-component, and then at least one structural sub-component is connected to form a structural part, so as to facilitate the use of structural parts to manufacture terminal equipment. The aforementioned steps can reduce the cost of structural manufacturing, and are not limited by molds. An integrated structure of multi-layer materials can be formed as needed, and the interfaces between the multi-layer materials have a high connection strength, thereby improving production stability; and structural sub-components including at least a portion of the frame and at least a portion of the middle plate can be manufactured as needed, and the structural sub-components can be formed into structural parts to improve production efficiency.

[0054] According to actual conditions, there are many ways to arrange the first material layer and the second material layer, so as to obtain a structural sub-component including at least a part of the frame and at least a part of the middle plate; Figure 6 As shown, in the first example, a first portion of the second material layer is added in a partial area of ​​the first material layer by a friction stir additive process, and the remaining area is not added; Figure 7 As shown, in the second example, the first material layer includes a first region and a second region, and a first portion of the second material layer is additively formed in the first region of the first material layer, and a second portion of the second material layer is additively formed in the second region of the first material layer through a friction stir additive process.

[0055] like Figure 7 As shown, according to the aforementioned second example, the second material layer 10 also includes a second part 12, the first part 11 and the second part 12 are distributed along the first material layer 20, and the height of the second part 12 is lower than the height of the first part 11; in this way, the connection strength and connection performance of at least one structural sub-component can be improved, thereby improving the structural strength of the terminal equipment structural component.

[0056] Specifically, in the process of forming an integrated structure including multiple layers of materials, the second material layer 10 can be added to the first material layer 20 through a stir friction additive process, wherein the second material layer 10 includes a first part 11 and a second part 12, and the first material layer 20 includes a fourth part 21 and a fifth part 22. The first part 11 of the second material layer 10 can be added to the fourth part 21 of the first material layer 20, and the second part 12 of the second material layer 10 can be added to the fifth part 22 of the first material layer 20, and the stir friction additive process makes the height of the second part 12 in the thickness direction lower than the height of the first part 11; when the structural sub-components are connected, the bending module can be controlled to bend the fifth part 22 relative to the fourth part 21, so that the second part 12 of the second material layer 10 is attached along the edge of the first part 11 of the second material layer 10. The materials of these two parts are the same, which facilitates welding between the first part 11 and the second part 12, improves the connection strength and connection performance, and thus improves the structural strength of the structural sub-components.

[0057] Furthermore, in some specific examples, a structural sub-component forms a structural component:

[0058] The first part 11 of the second material layer 10 can form a complete middle plate, the first material layer 20 and the second part 12 of the second material layer 10 can form a complete frame, the fifth part 22 of the first material layer 20 is fitted along multiple edges of the middle plate through multiple bendings, and the second part 12 of the second material layer 10 also bends following the fifth part 22 of the first material layer 20; when connecting, the first part 11 and the second part 12 of the second material layer 10 can be welded together, so as to connect the frame and the middle plate and improve the structural strength of the structural parts.

[0059] like Figure 8 As shown, in some embodiments of the present invention, the second material layer 10 also includes a third part 13, and the second part 12, the first part 11 and the third part 13 are distributed in sequence along the first material layer 20, and the height of the third part 13 is lower than the height of the first part 11; in this way, the connection strength and connection performance of at least one structural sub-component can be improved, thereby improving the structural strength of the terminal equipment structural component.

[0060] Specifically, in the process of forming an integrated structure including multiple layers of materials, the second material layer 10 can be added to the first material layer 20 by the friction stir additive process, wherein the second material layer 10 includes a first portion 11, a second portion 12 and a third portion 13, the first material layer 20 includes a fourth portion 21, a fifth portion 22 and a sixth portion 23, the first portion 11 of the second material layer 10 can be added to the fourth portion 21 of the first material layer 20, the second portion 12 of the second material layer 10 can be added to the fifth portion 22 of the first material layer 20, and the third portion 13 of the second material layer 10 can be added to the first material layer 20. The sixth part 23 of the material layer 20 is added material, and through the stir friction additive process, the height of the third part 13 and the height of the second part 12 in the thickness direction are lower than the height of the first part 11; when the structural sub-components are connected, the fifth part 22 and the sixth part 23 can be bent relative to the fourth part 21, so that the second part 12 and the third part 13 of the second material layer 10 are fitted along the edge of the first part 11. The materials of these three parts are the same, which facilitates the welding between the first part 11 and the second part 12 and the third part 13, improves the connection strength and connection performance, and thus improves the structural strength of the structural sub-components.

[0061] like Figure 8As shown, in some embodiments of the present invention, the first material layer 20 includes a fourth portion 21, a fifth portion 22 and a sixth portion 23, the fourth portion 21 corresponds to the first portion 11, the fifth portion 22 corresponds to the second portion 12, the sixth portion 23 corresponds to the third portion 13, and the fifth portion 22, the fourth portion 21 and the sixth portion 23 are an integrated structure distributed along a preset direction, wherein the length of the sixth portion 23 in the preset direction is greater than the length of the fifth portion 22 in the preset direction, and the total height of the first portion 11 and the fourth portion 21; in this way, the contact area between the structural sub-components can be increased to improve the connection strength between the structural sub-components, thereby improving the structural strength of the structural components. And combined with Figure 8 , the preset direction is the first direction AA.

[0062] It can be understood that when the structural sub-component includes two, the two structural sub-components can be connected in a centrally symmetrical form to form a structural component; specifically, the length of the fifth part 22 in the preset direction is less than the total height of the first part 11 and the fourth part 21. Before the two structural sub-components are connected, the fifth part 22 and the sixth part 23 of one structural sub-component can be bent 90°, and the sixth part 23 of the structural sub-component extends a part relative to the first part 11, and the fifth part 22 retracts a part relative to the first part 11, and the other structural sub-component also forms the same structure after bending. In this way, the two structural sub-components are connected in a centrally symmetrical form. The structural components are connected in a symmetrical manner. The sixth part 23 and the third part 13 of one structural component can be connected to the fifth part 22 and the second part 12 of another structural component, and can be placed on the edge of the first part 11 of the other structural component. Similarly, the sixth part 23 and the third part 13 of another structural component can be connected to the fifth part 22 and the second part 12 of a structural component, and can be placed on the edge of the first part 11 of a structural component, so as to increase the contact area between the structural components, improve the connection strength between the structural components, and thus improve the structural strength of the structural components.

[0063] In some embodiments of the present invention, the hardness of the first material layer is greater than that of the second material layer, and the welding performance of the second material layer is better than that of the first material layer; it can be understood that the frame of the terminal device can be obtained by cutting the first material layer, and the middle plate of the terminal device can be obtained by cutting the second material layer. In this way, the hardness of the frame is relatively large, which can resist the impact on the structural parts of the terminal device and avoid damage to the structural parts of the terminal device. The second material layer can improve the welding performance of the structural sub-components and improve the connection strength of the structural sub-components, thereby improving the structural strength of the structural parts.

[0064] like Figure 2 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:

[0065] Step S110, depositing a second material layer on the first material layer along a first direction using a friction stir additive process to obtain an integrated structure including the first material layer and the second material layer, wherein the first direction has an angle less than 90° with a preset blanking plane.

[0066] Specifically, the controller or operator can control the additive spindle head of the additive module to move along the first direction on the first surface of the substrate and maintain stirring friction with the substrate (the first material layer is the substrate, and the second material layer is formed by additive). It can be understood that the additive direction of the additive spindle head is perpendicular to the thickness direction, that is, the first direction is perpendicular to the thickness direction. In addition, the first direction can have an angle of less than 90° with the preset blanking plane. In this way, after controlling the blanking module to perform blanking processing on the integrated structure, the extension direction of the second material layer on the obtained structural sub-component has an angle of less than 90° with the first direction, so that the second material layer in the structural sub-component is more uniform. When the frame member is further processed, for example, bent, in the subsequent process, the cracking of the second material layer in the structural sub-component can be reduced, thereby improving production stability. Preferably, the first direction is also parallel to the preset blanking plane to further improve the uniformity of the second material layer.

[0067] It should be explained that the first direction is the direction along the first surface of the substrate. If the first surface of the substrate is a plane, the first direction is parallel to the first surface; if the first surface of the substrate is a curved surface, the first direction is parallel to the tangent of a point on the first surface.

[0068] In actual situations, after the second material layer is deposited on the first material layer, the additive spindle head of the additive module can be controlled to move along the thickness direction to the surface of the second material layer, and the additive spindle head can be controlled to move along the first direction again to deposit and manufacture a third material layer on the second material layer. It can be understood that the first direction is perpendicular to the thickness direction.

[0069] like Figure 3 As shown, in some embodiments of the present invention, before connecting at least one structural sub-component to form a structural component, the manufacturing method further includes:

[0070] Step S210 , bending at least one structural component toward the second material layer to form a first structural portion and a second structural portion connected in sequence, or to form a first structural portion, a second structural portion and a third structural portion connected in sequence.

[0071] It is understandable that, in order to facilitate the mutual connection between multiple structural sub-components, or the connection between the structural sub-components themselves, the operator or the controller can control the bending module to bend the structural sub-component toward the second material layer once, forming a first structural part and a second structural part connected in sequence; specifically, the second structural part may include the first part of the second material layer and the fourth part of the first material layer, and the first structural part may include the second part of the second material layer and the fifth part of the first material layer, so that the second part of the second material layer and the fifth part of the first material layer can be adapted to the shape of the first part of the second material layer to improve the connection strength between the structural sub-components themselves and the multiple structural sub-components. Among them, the first structural part and the second structural part can be connected in an "L" shape.

[0072] Alternatively, the bending module can be controlled to bend the structural sub-component toward the second material layer once to form a first structural part, a second structural part, and a third structural part connected in sequence; specifically, the second structural part may include the first part of the second material layer and the fourth part of the first material layer, the first structural part may include the second part of the second material layer and the fifth part of the first material layer, and the third structural part may include the third part of the second material layer and the sixth part of the first material layer, so that the second part of the second material layer, the third part of the second material layer, the fifth part of the first material layer, and the sixth part of the first material layer can be adapted to the shape of the first part of the second material layer to improve the connection strength of the structural sub-component itself or between multiple structural sub-components. Among them, the first structural part, the second structural part, and the third structural part can be connected in a "U" shape.

[0073] like Figure 3 As shown, in some other embodiments of the present invention, before connecting at least one structural sub-component to form a structural component, the manufacturing method further includes:

[0074] Step S220 , bending at least one structural component toward the second material layer to form a first structural portion and a second structural portion connected in sequence.

[0075] Step S230 , bending the at least one structural component toward the second material layer again to form a first structural portion, a second structural portion, and a third structural portion that are connected in sequence.

[0076] Specifically, in order to facilitate the mutual connection between multiple structural sub-components, or the connection of the structural sub-components themselves, the operator or the controller can control the bending module to bend the structural sub-component toward the second material layer to form a first structural part and a second structural part connected in sequence, and then the bending module bends the structural sub-component again to form a first structural part, a second structural part and a third structural part connected in sequence; wherein the second structural part may include a first part of the second material layer and a fourth part of the first material layer, the first structural part may include a second part of the second material layer and a fifth part of the first material layer, and the third structural part may include a third part of the second material layer and a sixth part of the first material layer, so that the second part of the second material layer, the third part of the second material layer, the fifth part of the first material layer and the sixth part of the first material layer can be adapted to the shape of the first part of the second material layer to improve the connection strength of the structural sub-component itself or between multiple structural sub-components. Wherein, the first structural part, the second structural part and the third structural part can be connected in a "U" shape.

[0077] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the first part corresponding to at least one structural sub-component forming the structural member is a middle plate component of the structural member, and the first material layer corresponding to at least one structural sub-component forming the structural member is a frame component of the structural member; in this way, when the terminal equipment structural member is formed, the first part of the second material layer can replace at least a part of the middle plate, and the first material layer can replace at least a part of the frame, so as to improve the production efficiency of the terminal equipment structural member.

[0078] It can be understood that the structural sub-component includes at least a portion of the frame and at least a portion of the middle plate; in some examples, the first portion of the second material layer is added to the fourth portion of the first material layer, and the remaining portion is not added, so that at least a portion of the frame is obtained by cutting from the first material layer, at least a portion of the middle plate is obtained by cutting from the first portion of the second material layer, and at least one structural sub-component is connected to form a structural component.

[0079] Furthermore, the fifth part and the sixth part of the first material layer are respectively added to form the second part and the third part of the second material layer, so that at least a part of the frame is obtained by cutting from the first material layer, and at least a part of the middle plate is obtained by cutting from the first part of the second material layer. When at least one structural sub-component is connected to form a structural component, the second part and the third part of the second material layer can be used as the middle part between the frame and the middle plate, which is convenient for indirect connection between the frame and the middle plate to improve the connection strength, thereby improving the structural strength of the structural component and improving the production efficiency of the structural component.

[0080] like Figure 4 As shown, in some embodiments of the present invention, the step S300 of connecting at least one structural sub-component to form a structural component includes:

[0081] Step S310, welding the middle plate and the frame by means of a friction stir welding process, and placing a keyhole formed by connecting the middle plate and the frame on the middle plate.

[0082] Specifically, the controller or the operator can control the stirring head of the connecting module to stir and rub the gap between the middle plate and the frame and extend into the gap. The stirring head moves along the gap between the middle plate and the frame and stirs and rubs to weld the outer peripheral surface of the middle plate to the inner peripheral surface of the frame. Compared with processes such as bolt connection, laser welding and nano injection molding, the embodiment of the present invention realizes the connection between the middle plate and the frame through the stir friction welding process, which can increase the welding depth between the middle plate and the frame, thereby improving the connection strength between the middle plate and the frame, and has good sealing performance and lower cost.

[0083] Furthermore, after the welding of the middle plate and the frame is completed, the stirring head of the connecting module can be controlled to stir and frictionally move toward the part of the middle plate away from the edge, the rotation of the stirring head can be stopped at the middle plate, and the stirring head can be pulled out of the middle plate, so that the keyhole generated by the stir friction welding process is placed on the middle plate. In this way, the connection strength between the middle plate and the frame can be improved, and the keyhole left on the middle plate can also be easily eliminated in subsequent machining, and will not affect the connection performance between the frame and the middle plate and the structural performance of the terminal equipment structural parts.

[0084] like Figure 1 As shown, in some embodiments of the present invention, the manufacturing method further includes:

[0085] 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.

[0086] Specifically, the operator or controller controls 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 rough-processes 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 the DDG process 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 fine-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.

[0087] 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 first material layer may be a 7-series aluminum alloy, the second material layer may be a 6-series aluminum alloy, or the first material layer may be titanium, and the second material layer may be a 6-series aluminum alloy. In this way, the first material layer has a higher structural strength, thereby improving the structural strength of the terminal equipment structural parts, and the second material layer has good welding performance, thereby improving the connection performance between the middle plate and the frame.

[0088] Based on the manufacturing method of the terminal device structural component of the aforementioned embodiment, the second aspect of the embodiment of the present invention proposes a computer-readable storage medium on which a manufacturing program of the terminal device structural component is stored. When the manufacturing program is executed by the processor, the manufacturing method of the terminal device structural component mentioned above is implemented.

[0089] According to the computer-readable storage medium of the embodiment of the present invention, the manufacturing program of the terminal device structural parts is executed by the processor, which can reduce the cost of structural manufacturing, and is not limited by the mold. An integrated structure of multi-layer materials can be formed as needed, and the interface between the multi-layer materials has a high connection strength, thereby improving production stability; and structural sub-components including at least a portion of the frame and at least a portion of the middle plate can be produced as needed, and the structural sub-components can be formed into structural parts to improve production efficiency.

[0090] According to a manufacturing device for a terminal device structural component of an embodiment of the third aspect of the present invention, the manufacturing device includes an additive module, a blanking module and a connecting module.

[0091] 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 along the thickness direction, wherein the integrated structure includes a first material layer and a second material layer, and the second material layer includes a first part, and the first part is protruding relative to the first material layer; the blanking module is used to blank the integrated structure along a preset blanking plane to obtain at least one structural sub-component, wherein the preset blanking plane is parallel to the thickness direction; the connecting module is used to connect at least one structural sub-component to form a structural component; in this way, the cost of structural manufacturing can be reduced, and it is not restricted by the mold, and an integrated structure of multiple layers of materials can be formed as needed, and the interface between the multiple layers of materials has a higher connection strength, thereby improving production stability; and structural sub-components including at least a portion of the frame and at least a portion of the middle plate can be produced as needed, and the structural sub-components are formed into structural components, thereby improving production efficiency.

[0092] Specifically, in the process of manufacturing the terminal device structural parts, first, the controller can control the additive spindle head of the additive module to move along the first direction on the surface of the substrate and stir friction, so that the additive material can be deposited on the substrate to form an integrated structure including a first material layer and a second material layer, the first material layer can be the substrate, and the second material layer can be formed by the additive material; wherein, the first material layer can be a 7-series aluminum alloy or titanium, providing good structural strength for the terminal device structural parts, and the second material layer can be a 6-series aluminum alloy to improve the connection performance between the middle plate and the frame in the terminal device; and by controlling the additive module to continue to add material, the first part of the second material layer is raised relative to the first material layer, so that when the structural parts are subsequently formed, the first part of the second material layer can replace at least a part of the middle plate, and the first material layer can replace at least a part of the frame, thereby improving the production efficiency of the structural parts. More specifically, the two structural sub-components are connected in a centrally symmetrical form to form the structural parts, so that the first part of the second material layer can replace a part of the middle plate, and the first material layer can replace half of the frame.

[0093] Then, the controller can control the cutting module to cut the integrated structure along a preset cutting plane to obtain two structural sub-components, wherein the preset cutting planes are parallel to the first direction and the thickness direction, respectively, and the first direction is perpendicular to the thickness direction, so that the extension direction of the second material layer of the cut structural sub-component is consistent with the first direction, so that the second material layer on the structural sub-component is evenly distributed, thereby avoiding cracking of the second material layer when the structural sub-component is subsequently bent.

[0094] The manufacturing device also includes a bending module, which is used to bend the structural sub-components toward the second material layer; after the aforementioned steps, the controller can control the bending module to bend the two structural sub-components toward the second material layer to form an "L"-shaped first structural portion and a second structural portion, or to bend them into a "U"-shaped first structural portion, a second structural portion and a third structural portion, so that the shape of the frame and the middle plate are adapted to improve the connection effect; then, the controller can first control the connection module to assemble the two structural sub-components together, and then control the stirring head of the connection module to move and stir friction along the gap between the middle plates of the two structural sub-components and along the gap between the middle plates of the two structural sub-components and the frame, thereby welding the two structural sub-components together. The stirring friction welding process can improve the connection strength of the structural sub-components, and have good sealing performance and low cost. Subsequently, the controller can control the stirring head of the connecting module to move toward the middle of the middle plate and pull the stirring head out of the middle plate, so that the keyhole formed by the stir friction welding process remains on the middle plate to improve the connection strength between the middle plate and the frame. The keyhole left on the middle plate is also easy to eliminate in subsequent machining, and will not affect the connection performance between the frame and the middle plate and the structural performance of the terminal equipment structural parts.

[0095] In summary, according to the manufacturing device of the terminal equipment structural parts of the embodiment of the present invention, an integrated structure including multiple layers of materials is manufactured by controlling the additive module, and then the blanking module is controlled to perform blanking processing on the integrated structure to obtain at least one frame member, and then the connection module is controlled to connect at least one structural sub-component to form a structural part, so as to facilitate the use of structural parts to manufacture terminal equipment. The cost of structural manufacturing can be reduced through the aforementioned steps, and it is not limited by the mold. An integrated structure of multiple layers of materials can be formed as needed, and the interface between the multiple layers of materials has a high connection strength, thereby improving production stability; and structural sub-components including at least a portion of the frame and at least a portion of the middle plate can be manufactured as needed, and the structural sub-components are formed into structural parts, thereby improving production efficiency.

[0096] 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 friction additive on the surface of the substrate, and the positioner is used to control the displacement of the substrate relative to the additive spindle head to achieve movement of the additive spindle head on the substrate; the blanking module may include a cutting machine for cutting structural sub-components from the integrated structure; the bending module may include a bending machine, and the bending machine is used to bend the structural sub-components toward the second material layer; the connecting module may include a stirring head and a clamp, and the stirring head is used to weld the middle plate and the frame through a stir friction welding process, and the clamp is used to place and assemble the two structural sub-components together, and clamp the two structural sub-components through the clamp to facilitate subsequent welding.

[0097] According to the terminal device of the fourth aspect of the embodiment of the present invention, the terminal device includes a structural part, and the structural part is manufactured according to the manufacturing method of the terminal device structural part mentioned above, which can reduce the cost of structural manufacturing and is not limited by the mold. An integrated structure of multi-layer materials can be formed as needed, and the interface between the multi-layer materials has a high connection strength, thereby improving production stability; and a structural sub-component including at least a part of the frame and at least a part of the middle plate can be manufactured as needed, and the structural sub-component can be formed into a structural part to improve production efficiency.

[0098] Terminal devices can be mobile phones, tablets, laptops, etc.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] like Figure 5 As shown, in some specific examples of the present invention, the method for manufacturing a terminal device structural component includes:

[0103] The first step is friction stir additive: solid phase deposition of material 2 on the material 1 substrate by friction stir additive method.

[0104] Deposit material 2 of a specified thickness on the material 1 substrate until the entire surface is covered, and deposit different thicknesses of material 2 at different locations. Stir friction additive can be delivered by rods, wires or powders.

[0105] In the second step, the deposited material is cut into strips of a specified width: saw blade cutting, laser cutting, water cutting or wire cutting can be used to form composite strips.

[0106] The third step is bending: bending the composite strips. Strips of the same or different lengths are bent into an L-shape or a U-shape. At least two bent strips can be assembled into a complete frame. Use a hydraulic press or a punching machine combined with a mold to bend the straight strips 90°.

[0107] Step 4: Assembly: Assemble the composite strips together to form a complete frame and a complete middle plate.

[0108] Step 5, friction stir welding: The composite frame is connected by friction stir welding. The stirring head is welded along all the butt joints and the keyhole is left on the middle plate.

[0109] Step 6, DDG process and CNC process: For the frame after friction stir welding, CNC is used for rough machining to remove surface burrs, etc., and then DDG grinding is used to grind and polish the upper and lower bottom surfaces, and finally CNC machining is performed to determine the shape and structure.

[0110] In the first example, material 1 is titanium, and material 2 is a 6-series aluminum alloy; in the second example, material 1 is a 7-series aluminum alloy, and material 2 is a 6-series aluminum alloy.

[0111] like Figure 5 As shown, in some specific examples of the present invention, step ① shows a plate made of material 1; step ② shows an integrated structure of the material 1 plate and the material 2 additive; step ③ shows the strip material obtained by cutting; step ④ shows the bending of the strip material; step ⑤ shows the assembly of two structural sub-components; step ⑥ shows the stir friction welding of two structural sub-components.

[0112] In some specific examples of the present invention, before step S100 of producing an integrated structure including multiple layers of material by a friction stir additive process, the substrate may be first subjected to a quality inspection, specifically, the appearance, size, material, etc. of the substrate may be inspected; then the substrate may be surface treated, for example, the substrate may be cleaned, the substrate may be sprayed, etc.

[0113] The embodiment of the present invention can realize the preparation of composite frames. First, it is necessary to realize the preparation of composite plates or composite strips of different materials. The main preparation method at present is hot rolling. Hot rolling is a process method in which the assembled metal billets are heated to a specified temperature and then sent into a rolling mill. Under high temperature and high pressure, the billets undergo plastic deformation, so that the dissimilar metals can be firmly welded. However, its equipment occupies a large area, has high production costs, and can only produce flat-plate composite materials. The friction stir additive method is also a solid-phase additive method. Composite layer materials can be deposited on a substrate. Because it is not restricted by molds, the height of the deposition can be uniform or different at different positions; its interface connection strength is high, and the production stability is high; the production cost is lower than that of the hot rolling method. The friction stir local additive method is used to deposit deposited materials of different thicknesses on the frame substrate, and materials that replace all or part of the middle plate can be deposited, which will provide more possibilities and imagination space for design.

[0114] In addition, the frame and the middle plate also need to be connected to form an overall structure. Currently available connection methods include bolt connection, laser welding, nano injection molding, etc. Bolt connection cannot achieve sealing, and the introduction of bolts will add extra weight; laser welding is difficult to weld aluminum alloys, has low stability, and has limited welding depth, and is expensive; nano injection molding relies on polymers to achieve the connection between the frame and the middle plate, but it is expensive and has low connection strength. Stir friction welding is a solid-phase connection method and is the most ideal choice for connecting aluminum to aluminum. Compared with the above three methods, it has the advantages of high connection strength, large welding depth, sealing, and low price.
