[0032] 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.

[0033] The present invention proposes a method for manufacturing a terminal device structural component, which can reduce the cost of manufacturing 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. A computer-readable storage medium, a manufacturing device for a terminal device structural component, and a terminal device are also proposed.

[0034] like Figure 1 , Figure 5 and Figure 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:

[0035] 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.

[0036] Specifically, the controller or the operator can control the additive spindle head in the additive module to perform stir friction on a layer of plate material. During this process, a visco-plastic deposition layer is formed by the friction heat generated by the friction between the additive material and the plate material and the plastic deformation caused by the violent deformation of the material. As multiple deposition layers are accumulated along the thickness direction of the plate material, an integrated structure including multiple layers of material is formed. 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 does not require a larger manufacturing device, is not restricted by molds, etc., and makes the interface between the multiple layers of material have a higher connection strength, thereby improving production stability.

[0037] In addition, according to the needs of the terminal equipment, the same or different types of material layers can be deposited on the plate. For example, titanium or 7-series aluminum alloy with good strength can be deposited on the substrate to form an integrated structure in which the substrate is a 6-series aluminum alloy and the additive layer is 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 in which the substrate is a 7-series aluminum alloy or titanium and the additive layer is a 6-series aluminum alloy.

[0038] Step S200, blanking the integrated structure along a preset blanking plane to obtain at least one frame member, wherein the preset blanking plane is parallel to the thickness direction.

[0039] 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 frame part can be obtained, the preset blanking plane is parallel to the thickness direction, and the obtained at least one frame part can include multiple layers of materials in the integrated structure, so as to obtain at least one frame part with predetermined performance. The blanking processing can be a cutting processing, that is, the integrated structure is cut to obtain at least one frame part.

[0040] 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.

[0041] Step S300: Connect at least one frame member to a middle plate to form a structural member.

[0042] Specifically, the frame member can be one, three, or five, etc. The connection module is controlled by the controller or the operator, and the connection module fixes at least one frame member to the periphery of the middle plate, and connects at least one frame member to the periphery of the middle plate to form a structural member of the terminal device. In some examples, the terminal device can be a mobile phone, and the frame members include four. The four frame members can be connected to the four sides of the middle plate respectively to form a complete mobile phone frame on the periphery of the middle plate. The frame is located at the edge of the mobile phone to resist the impact on the mobile phone. The middle plate forms a support plate for the mobile phone, and the middle plate provides support and installation points for the functional components of the mobile phone.

[0043] Therefore, according to the manufacturing method of the terminal device 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 frame member, and then the at least one frame member is connected to the middle plate to form a structural member, so as to facilitate the use of the structural members to manufacture terminal devices. The aforementioned steps can reduce the cost of structural parts 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 higher connection strength, thereby improving production stability.

[0044] like Figure 5 As shown, in some embodiments of the present invention, the one-piece structure may include a first material layer (ie Figure 5 Material 1 in) and the second material layer (ie Figure 5 In the material 2), the first material layer is used as the outer layer of the frame member, and the second material layer is used as the inner layer of the frame member; specifically, the second material layer can be used to connect with the middle plate, and the first material layer can be used to prevent the appearance of the terminal device structure from being damaged; more specifically, when the frame member is connected to the middle plate, the controller or operator can control the connection module to relatively fix the inner layer of the frame member and the periphery of the middle plate together, and connect the inner layer of the frame member to the middle plate. Of course, according to actual conditions, the integrated structure can also include the third material layer, the fourth material layer and other remaining material layers, and the remaining material layers can be located between the first material layer and the second material layer.

[0045] Furthermore, 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 first material layer can resist the impact on the terminal device structural parts and avoid damage to the terminal device structural parts, and the second material layer can improve the welding performance of the terminal device structural parts.

[0046] 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:

[0047] Step S110, using a stir friction additive process to deposit a second material layer on the first material layer along a first direction 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.

[0048] Specifically, the controller or operator controls the additive spindle head of the additive module to move along the first direction on the surface of the first material layer 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 also has 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 frame member has an angle of less than 90° with the first direction, so that the second material layer in the frame member is more uniform. When the frame member is further processed subsequently, such as bending processing, the cracking of the second material layer in the frame member can be reduced, thereby improving production stability. Preferably, the first direction has an angle of 0° with the preset blanking plane to further improve the uniformity of the second material layer.

[0049] It should be explained that the first direction can be understood as a direction along the surface of the substrate. If the surface of the substrate is a plane, the first direction is parallel to the first surface; if the surface of the substrate is a curved surface, the first direction is parallel to the tangent of a point on the surface.

[0050] According to actual conditions, 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.

[0051] like Figure 3 As shown, in some embodiments of the present invention, before the step S300 of connecting at least one frame member to the middle plate to form a structural member, the manufacturing method further includes:

[0052] Step S210, bending at least one frame member toward the inner surface of the inner layer of the frame member to form a first frame portion and a second frame portion connected in sequence, or to form a first frame portion, a second frame portion and a third frame portion connected in sequence.

[0053] It is understandable that, in order to facilitate the connection between the frame member and the middle plate, according to the structure of the middle plate, the operator or the controller can control the bending module to bend the frame member toward the inner layer of the frame member once to form the first frame part and the second frame part connected in sequence, and the first frame part and the second frame part can be respectively adapted to the edge shape of the middle plate, or the shape formed by the connection of the first frame part and the second frame part is adapted to the edge shape of the middle plate, so as to improve the connection adaptability and connection strength between the frame member and the middle plate. Among them, the first frame part and the second frame part can be connected to form an "L" shape. In some examples, the middle plate is a rectangular parallelepiped, and the frame member may include four. The connection module fixes the four frame members at the four corners of the middle plate respectively, and connects the four frame members to the edge of the middle plate to form a structural member.

[0054] Alternatively, the bending module can be controlled to bend the frame member toward the inner layer of the frame member once to form a first frame part, a second frame part, and a third frame part connected in sequence, and the first frame part, the second frame part, and the third frame part can be respectively adapted to the edge shape of the middle plate, or the shape formed by connecting the first frame part, the second frame part, and the third frame part is adapted to the edge shape of the middle plate, so as to improve the connection adaptability and connection strength between the frame member and the middle plate. Among them, the first frame part, the second frame part, and the third frame part can be connected to form a "U" shape.

[0055] Furthermore, if Figure 3 As shown, in some embodiments of the present invention, the manufacturing method further includes:

[0056] Step S220 , bending at least one frame member toward the inner surface of the inner layer of the frame member to form a first frame portion and a second frame portion that are connected in sequence.

[0057] Step S230, bending at least one frame member toward the inner surface of the inner layer of the frame member again to form a first frame portion, a second frame portion and a third frame portion that are connected in sequence.

[0058] It is understandable that, in order to facilitate the connection between the frame member and the middle plate, according to the structure of the middle plate, the operator or the controller can control the bending module to bend the frame member toward the inner layer of the frame member to form the first frame part and the second frame part connected in sequence, and then the bending module bends the frame member again to form the first frame part, the second frame part and the third frame part connected in sequence, and the first frame part, the second frame part and the third frame part can be respectively adapted to the edge shape of the middle plate, or the shape formed by the connection of the first frame part, the second frame part and the third frame part is adapted to the edge shape of the middle plate, so as to improve the connection adaptability, connection convenience and connection strength of the frame member and the middle plate. Among them, the first frame part, the second frame part and the third frame part can be connected to form a "U" shape. In some examples, the middle plate is a rectangular parallelepiped, and the frame member may include two, and the connecting module fixes the two frame members to the edge of the middle plate respectively, and connects the two frame members to the edge of the middle plate to form a structural member.

[0059] In combination with step S210, step S220 and step S230, it can be understood that the above-mentioned "U"-shaped first frame portion, second frame portion and third frame portion can be realized through a single bending process, and does not necessarily have to be realized through two bending processes.

[0060] like Figure 4 As shown, in some embodiments of the present invention, the step S300 of connecting at least one frame member with a middle plate to form a structural member includes:

[0061] Step S310, forming at least one frame member into a frame.

[0062] It is understandable that when there is one frame member, one frame member can form a frame; when there are multiple frame members, multiple frame members can be combined to form a frame. Specifically, the controller or the operator controls the connection module, and the connection module can position at least one frame member on the periphery of the middle plate and assemble at least one frame member into a frame. In this way, at least one frame member can be formed into a frame according to the shape of the middle plate, so as to facilitate the connection between the frame and the middle plate.

[0063] Step S320, welding the outer peripheral surface of the middle plate to the inner layer of the frame member of the frame by a stir friction welding process, and placing a keyhole formed by connecting the middle plate and the inner layer of the frame member on the middle plate.

[0064] 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 inner layer of the frame member and extend into the gap. The stirring head moves along the gap between the middle plate and the inner layer of the frame member and stirs and rubs to weld the outer peripheral surface of the middle plate to the inner layer of the frame member. 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 a stir friction welding process, which can increase the welding depth between the middle plate and the frame member, thereby improving the connection strength between the middle plate and the frame member, and has good sealing performance and lower cost.

[0065] Furthermore, after the inner layer 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, which will not affect the connection performance between the frame and the middle plate and the structural performance of the terminal equipment structural parts.

[0066] like Figure 1 As shown, in some embodiments of the present invention, the manufacturing method further includes:

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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 in the aforementioned embodiment is implemented.

[0071] 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, so that the cost of manufacturing the structural parts can be reduced without being restricted 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.

[0072] 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.

[0073] 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. The blanking module is used to blank the integrated structure along a preset blanking plane to obtain at least one frame member, wherein the preset blanking plane is parallel to the thickness direction. The connecting module is used to connect at least one frame member with the middle plate to form a structural member; in this way, the cost of manufacturing structural members can be reduced, and it is not restricted 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 higher connection strength, thereby improving production stability.

[0074] Specifically, in the process of manufacturing terminal equipment structural parts, first, the controller can control the stirring head of the additive module to move along the first direction on the surface of the plate and stir and rub, so that the additive material can be deposited on the plate to form an integrated structure including a first material layer and a second material layer. The first material layer can be a plate, and the second material layer can be formed by additive material; wherein the first material layer can be 7 series aluminum alloy or titanium to provide good structural strength for the terminal equipment structural parts, and the second material layer can be 6 series aluminum alloy to improve the connection performance between the middle plate and the frame parts in the terminal equipment.

[0075] Then, the controller can control the cutting module to cut the integrated structure along a preset cutting plane to obtain at least one frame member, wherein the preset cutting plane is 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 frame member is consistent with the first direction, so that the second material layer on the frame member is evenly distributed, thereby avoiding cracking of the second material layer when the frame member is subsequently bent.

[0076] The manufacturing device also includes a bending module, which is used to bend at least one frame member toward the inner surface of the inner layer of the frame; after the above steps, the controller can control the bending module to bend multiple frame members toward the inner surface of the inner layer of the frame member to form an "L"-shaped first frame part and a second frame part, or to bend to form a "U"-shaped first frame part, a second frame part and a third frame part, so that the frame member is adapted to the shape of the middle plate to improve the connection effect; then, the controller can control the stirring head of the connection module to move along the gap between the middle plate and the frame and stir friction, so as to weld the middle plate and the frame together, and the friction stir welding process can improve the structural strength of the structural member, and have good sealing performance and low cost. Subsequently, the controller can control the stirring head of the connection 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 friction stir welding process remains on the middle plate, so as to improve the connection strength between the middle plate and the frame, and the keyhole left on the middle plate is also convenient for elimination in subsequent machining, which will not affect the connection performance between the frame and the middle plate and the structural performance of the terminal device structural member.

[0077] 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 part, and then the connecting module is controlled to connect the at least one frame part with the middle plate 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 parts manufacturing, and are not restricted by molds. An integrated structure of multiple layers of materials can be formed as needed, and the interfaces between the multiple layers of materials have a higher connection strength, thereby improving production stability.

[0078] 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 realize the movement of the additive spindle head on the substrate; the blanking module may include a cutting machine; the bending module may include a bending machine, and the bending machine is used to bend at least one frame member toward the inner surface of the inner layer of the frame; the connecting module may include a stirring head and a clamp. 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 at least one frame member and the middle plate together, and clamp and fix at least one frame member and the middle plate through the clamp to facilitate subsequent welding.

[0079] According to the terminal device of the fourth aspect 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 embodiment, which can reduce the cost of manufacturing the structural parts and is not limited by the mold. An integrated structure of multi-layer materials can be formed as needed, and the interfaces between the multi-layer materials have a higher connection strength, thereby improving production stability.

[0080] Terminal devices can be mobile phones, tablets, laptops, etc.

[0081] 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.

[0082] 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 plate 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.

[0083] 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.

[0084] like Figure 5 As shown, in some specific examples of the present invention, the method for manufacturing a terminal device structural component includes:

[0085] The first step is friction stir additive manufacturing: solid phase deposition of material 2 is performed on a plate of material 1 by means of friction stir additive manufacturing.

[0086] Deposit material 2 of a specified thickness on the plate of material 1 until the entire surface is covered. Friction stir additive can be produced by feeding rods, wires or powders.

[0087] 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.

[0088] 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°.

[0089] Step 4: Assembling: Assemble the middle plate and the frame consisting of the bent composite strips together.

[0090] The fifth step is friction stir welding: the deposited layers of the middle plate and the frame are connected by friction stir welding. The stirring head welds along all the butt joints and leaves the keyhole on the middle plate.

[0091] Step 6: DDG process and CNC process. For the frame middle plate 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.

[0092] In the first example, material 1 is titanium, material 2 is 6-series aluminum alloy, and the middle plate is 6-series aluminum alloy. In the second example, material 1 is 7-series aluminum alloy, material 2 is 6-series aluminum alloy, and the middle plate is 6-series aluminum alloy.

[0093] 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 cutting the integrated structure into multiple strips; step ④ shows the strips obtained by cutting; step ⑤ shows bending the strips; step ⑥ shows assembling the bent strips with the middle plate; step ⑦ shows friction stir welding of the bent strips with the middle plate.

[0094] In some specific examples of the present invention, before step S100 of producing an integrated structure including multiple layers of material through a stir friction additive process, the quality of the plate may be checked first, specifically, the appearance, size, material, etc. of the plate may be checked; then the plate may be surface treated, for example, by cleaning the plate, spraying the plate, etc.

[0095] 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 preparation method of the related technology is hot rolling. Hot rolling is a process 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 together. 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, which can deposit composite layer materials on a substrate. Because it is not restricted by molds, etc., the deposition height can be uniform or different in height 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.

[0096] In addition, the frame and the middle plate also need to be connected to form an integral structure. The connection methods in the related technologies 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 of aluminum alloys is difficult, 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 its price is high and the connection strength is low. 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.
