Description

Technical Field

[0001] This application relates to the field of terminal technology, and in particular to a magnet assembly device and a magnet assembly method. Background Technology

[0002] With the gradual maturation of flexible screen technology, the way electronic devices are displayed has undergone tremendous changes. One of these changes is the emergence of foldable mobile phones, computers, and other electronic devices. The flexible screens of foldable electronic devices can flexibly switch modes according to different usage scenarios, while also having a high screen ratio and high clarity. For example, a foldable mobile phone can be folded to the size of a traditional mobile phone, making it easy to carry, while unfolding it can have the display size of a tablet. These features make foldable devices one of the most sought-after products.

[0003] Currently, foldable electronic devices, taking a two-layer foldable device as an example, generally consist of two housings connected by a folding assembly. This allows the two housings to rotate relative to each other, enabling them to fold closed or unfold. Typically, magnets are placed in each housing. When the two housings rotate to overlap, i.e., in the closed state, the two magnets attract each other, thus keeping the electronic device closed and preventing it from spontaneously opening. The magnets are usually attached by applying adhesive to mounting slots in the housings.

[0004] However, in the assembly of magnets, the height position of the magnet relative to the housing (the position in the z-direction of the thickness of the electronic device) is difficult to control due to the influence of magnet size, housing magnet slot size, adhesive thickness, and pressure holding effect, which reduces the magnet assembly yield and affects the assembly efficiency of electronic devices. For example, when the magnet needs to be flush with the plane of the housing, if the magnet is inserted too deeply into the assembly slot, there will be a recessed step difference between the magnet and the housing, or the magnet will protrude from the assembly slot, resulting in a raised step difference between the magnet and the housing. Both of these will cause poor assembly and require disassembly and reassembly. Summary of the Invention

[0005] This application provides a magnet assembly device and a magnet assembly method, which solves the problem that the height position of the magnet relative to the shell is difficult to control in the assembly of magnets in existing electronic devices, thus affecting the magnet assembly yield.

[0006] The first aspect of this application provides a magnet assembly apparatus for assembling magnets on electronic devices, comprising: a base, a first cover plate and a second cover plate respectively disposed on the base;

[0007] The base is used to support the housing of the electronic device. The first cover plate and the second cover plate are respectively used to press on the side of the housing facing away from the base. The second cover plate is pressed on the end of the housing where the magnet is provided. The second cover plate at least covers part of the magnet.

[0008] It also includes a magnetic component, which is disposed on the side of the second cover plate facing away from the base. The magnetic component attracts the magnet. By pressing the second cover plate onto the housing, and the second cover plate covering at least part of the magnet, that is, part of the second cover plate is pressed onto the housing and part of the second cover plate covers the magnet. A magnetic component is disposed on the side of the second cover plate facing away from the base, and the magnetic component attracts the magnet. In other words, by pressing the second cover plate onto the housing, part of the second cover plate contacts the plane of the housing, and under the action of the magnetic component, part of the second cover plate contacts the magnet, thereby keeping the magnet flush with the plane of the housing, eliminating the protrusion or depression difference between the magnet and the housing, accurately fixing the height of the magnet in the z-axis, and improving the yield of magnet assembly.

[0009] When a magnet is placed in the assembly slot, a raised step difference is formed between the magnet and the housing. The pressing and squeezing action of the second cover plate on the magnet causes it to move towards the bottom of the assembly slot, thereby reducing or eliminating the raised step difference and making the magnet flush with the housing. Simultaneously, due to the mutual attraction between the magnetic component and the magnet, when the magnet moves excessively towards the bottom of the assembly slot under the influence of gravity, the magnetic component can hold the magnet in place, ensuring a gapless contact between the magnet and the second cover plate, thus keeping the magnet flush with the plane of the housing. This further effectively controls the height of the magnet, ensuring it remains flush with the plane of the housing.

[0010] When the magnet is placed in the assembly slot, a recessed step is formed between the magnet and the housing. The second cover plate is pressed onto the housing, and the magnetic component is placed on the second cover plate. Because the second cover plate is pressed onto the housing, there is no gap between the side of the second cover plate facing the housing and the flat surface of the housing. The magnetic component can attract the magnet, causing it to move towards the second cover plate, and ultimately making the magnet in close contact with the flat surface of the second cover plate facing the housing. This keeps the magnet flush with the flat surface of the housing, eliminating the recessed step between the magnet and the housing, making the magnet flush with the housing, and improving the yield of magnet assembly.

[0011] In one possible implementation, the second cover plate has a pressing boss on its side facing the base. The area of ​​the pressing boss facing away from the second cover plate is smaller than the area of ​​the side of the second cover plate facing the base. Part of the pressing boss presses onto the housing, and part of the pressing boss presses onto the magnet. Thus, when the second cover plate is pressed onto the housing, the pressing boss on the second cover plate contacts the housing, meaning that the side of the pressing boss facing away from the second cover plate contacts the plane of the housing without gap. The seamless contact between the side of the pressing boss facing away from the second cover plate and the magnet ensures the flushness between the magnet and the housing. Since the area of ​​the pressing boss facing away from the second cover plate is smaller than the area of ​​the side of the second cover plate facing the base, using a smaller pressing boss to contact the first housing reduces or avoids the influence of different housing plane heights on the magnet's height position, further improving the flushness of the magnet and the housing around the assembly slot, which helps improve the yield rate of magnet assembly.

[0012] In one possible implementation, a controller is also included, wherein the second cover plate is a deformable component. The controller is used to control the magnetic component to change the magnetic attraction between the magnetic component and the magnet. By making the second cover plate a deformable component, the deformation of the deformable component can make the magnet and the housing flush, or form accurate recesses or protrusions, enabling the assembly device to be applicable to different scenario requirements and to accurately fix the height of the magnet in the z-direction, effectively improving the applicability of the assembly device.

[0013] In one possible implementation, the base has a raised support platform that extends into and supports the housing. The support platform provides support to the housing while restricting movement of the first housing in the z-direction (the thickness direction of the electronic device), thus allowing the first housing to be mounted on the base.

[0014] In one possible implementation, a first limiting member is provided on the support platform, which cooperates with a second limiting member on the housing. When the first housing is placed on the support platform of the base, the first and second limiting members cooperate to limit the first housing in the x-direction (width direction of the electronic device) and y-direction (length direction of the electronic device) as shown in the figure, thereby fixing the first housing to the base. This can prevent the first housing from moving during magnet assembly, which helps to improve the accuracy of magnet assembly and increase the assembly yield.

[0015] In one possible implementation, the first limiting member is a limiting post formed by a protrusion facing away from the base.

[0016] In one possible implementation, a first mounting member is also included, one end of the first cover plate being disposed on the base via the first mounting member, and the other end of the first cover plate being pressed against the housing.

[0017] In one possible implementation, a second mounting element is also included, one end of the second cover plate being mounted on the base via the second mounting element, and the other end of the second cover plate being pressed against the housing.

[0018] A second aspect of this application provides a magnet assembly device, comprising: a base, a first cover plate and a second cover plate respectively disposed on the base;

[0019] The base is used to support the housing of the electronic device. The first cover plate and the second cover plate are respectively used to press on the side of the housing facing away from the base. The second cover plate is pressed on the end of the housing where the magnet is provided. The second cover plate at least covers part of the magnet.

[0020] It also includes a magnetic component, which is disposed on the side of the second cover plate facing away from the base, and the magnetic component is attracted to the magnet;

[0021] A pressure block is also provided on the side of the second cover plate facing the base. The pressure block is used to extend into the assembly groove on the housing to accommodate the magnet. When the second cover plate is pressed onto the housing and the pressure block extends into the assembly groove, the force between the magnetic component and the magnet, or the squeezing force of the pressure block on the magnet, will ultimately cause the magnet to come into contact with the pressure block. That is, there is no gap between the plane of the second cover plate and the housing, and the pressure block on the second cover plate extends into the assembly groove to contact the magnet. The thickness of the pressure block in the z-direction is the distance between the plane of the magnet and the housing, forming a recessed step between the magnet and the housing. The thickness of the pressure block can be precisely controlled, thus achieving precise fixation of the magnet's height in the z-direction, ensuring that the recessed step between the magnet and the housing is a preset recessed step, effectively improving the yield of magnet assembly.

[0022] A third aspect of this application provides a magnet assembly device, comprising: a base, a first cover plate and a second cover plate respectively disposed on the base;

[0023] The base is used to support the housing of the electronic device. The first cover plate and the second cover plate are respectively used to press on the side of the housing facing away from the base. The second cover plate is pressed on the end of the housing where the magnet is provided. The second cover plate at least covers part of the magnet.

[0024] It also includes a magnetic component, which is disposed on the side of the second cover plate facing away from the base. The magnetic component attracts the magnet. The side of the second cover plate facing the base has a recessed clearance groove for accommodating the magnet. When the second cover plate is pressed onto the housing, the magnet extends into the clearance groove under the action of the magnetic component and contacts the housing. Because the clearance groove is recessed, the magnet extends beyond the mounting groove, protruding from the housing, creating a step difference between the magnet and the housing. The depth of the clearance groove can be precisely controlled, thereby accurately fixing the magnet in the desired position and achieving precise control over the step difference between the magnet and the housing.

[0025] A fourth aspect of this application provides a magnet assembly method, which assembles a magnet onto an electronic device using any of the magnet assembly devices described above, the method comprising:

[0026] The housing of the electronic device is mounted on the base;

[0027] The first cover plate is pressed onto the side of the housing facing away from the base;

[0028] Apply adhesive to the assembly slot of the housing and place a magnet thereon;

[0029] The second cover plate is pressed onto the side of the housing facing away from the base, and the second cover plate is pressed onto the end of the housing where the magnet is provided, and the second cover plate at least covers part of the magnet;

[0030] A magnetic component is placed on the side of the second cover plate facing away from the base, so that the magnetic component is attracted to the magnet.

[0031] After standing, remove the magnetic component, the second cover plate, and the first cover plate from the housing in sequence.

[0032] In one possible implementation, dispensing adhesive in the assembly groove of the housing includes: having support blocks on opposite sides of the assembly groove, and distributing the adhesive between the two support blocks.

[0033] In one possible implementation, the thickness of the support block is 0.05-0.15 mm. Attached Figure Description

[0068] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0069] This application provides a magnet assembly device for assembling magnets on an electronic device, thereby assembling the magnets onto the casing of the electronic device. Specifically, the electronic device may include, but is not limited to, foldable fixed or mobile terminals such as mobile phones, tablets, laptops, ultra-mobile personal computers (UMPCs), handheld computers, touch-screen TVs, walkie-talkies, netbooks, POS machines, personal digital assistants (PDAs), wearable devices, and virtual reality devices.

[0070] In this embodiment of the application, the assembly of magnets on a foldable mobile phone using the magnet assembly device is used as an example for illustration. The foldable mobile phone can be a foldable mobile phone with an outward folding screen, or a foldable mobile phone with an inward folding screen, or a foldable mobile phone with an inward folding screen and an attached outer screen.

[0071] Figure 1 This is a schematic diagram of a foldable phone in a flattened state, provided in an embodiment of this application. Figure 2 This is a schematic diagram of a foldable mobile phone in a folded state, provided as an embodiment of this application.

[0072] See Figure 1 and Figure 2 As shown, the foldable phone 200 may include at least a folding assembly 203 and housings located on both sides of the folding assembly 203. For example, the two housings are a first housing 201 and a second housing 202, respectively. The first housing 201 and the second housing 202 are respectively connected to the folding assembly 203. At the same time, the first housing 201 and the second housing 202 can be rotatably connected through the folding assembly 203, so that the first housing 201 and the second housing 202 can rotate relative to each other, that is, the first housing 201 and the second housing 202 can rotate relative to each other.

[0073] The first housing 201 and the second housing 202 can be unfolded relative to each other to an open state, so that the foldable phone 200 is in an open state, also known as a flattened state. See, for example... Figure 1 As shown, when the first housing 201 and the second housing 202 are in the open state, they can be approximately 180° apart (a slight deviation is allowed, such as 165°, 177° or 185°).

[0074] The first housing 201 and the second housing 202 can rotate relative to each other (unfold or fold) to an intermediate state so that the foldable phone 200 is in an intermediate state.

[0075] See Figure 2 As shown, the first housing 201 and the second housing 202 can be folded relative to each other to a closed state, so that the foldable phone 200 is in a closed state, also known as a folded state. For example, when the first housing 201 and the second housing 202 are in the closed state, they can be completely closed to be parallel to each other (a slight deviation is also allowed). The intermediate state of the foldable phone 200 can be any state between the open state and the closed state. Therefore, the foldable phone 200 can switch between the open state and the closed state through the movement of the folding component 203.

[0076] The foldable phone 200 may further include a foldable flexible display screen, wherein the flexible display screen may be disposed on the same side surface of the first housing 201, the second housing 202, and the folding assembly 203. When the first housing 201 and the second housing 202 are folded relative to each other, the flexible display screen is attached to the first housing 201 and the second housing 202, and the portion of the flexible display screen opposite to the folding assembly 203 is bent and at least partially located within the screen-accommodating space enclosed by the folding assembly 203. When the first housing 201 and the second housing 202 are unfolded relative to each other, the flexible display screen also unfolds accordingly.

[0077] To ensure that the foldable phone 200 can remain stably closed for an extended period, magnets 24 are typically placed on the two casings of the foldable phone 200. Two corresponding magnets 24 located on the two casings can attract each other. See [link / reference] Figure 2 As shown, when the foldable phone 200 is in the closed state, the two magnets 24 attract each other, thereby restricting the relative rotation between the first shell 201 and the second shell 202, so that the foldable phone 200 is locked and remains stably in the closed state for a long time.

[0078] Therefore, the magnet 24 is one of the key components providing locking force for the foldable phone 200. In this embodiment, the magnet 24 installed on the first housing 201 of the foldable phone 200 is used as an example for explanation. The common method of assembling the magnet 24 is as follows: a mounting groove 211 is machined on the first housing 201, adhesive is applied to the mounting groove 211, and then the magnet 24 is installed on the first housing 201 through the adhesive layer 25 formed by the adhesive application. However, this assembly method makes it difficult to control the height of the magnet 24, that is, it is difficult to control the height position of the magnet 24 relative to the housing (refer to...). Figure 2As shown, this is the height in the thickness direction z upward of the first housing 201. The relative height position between the magnet 24 and the housing will affect the performance of the foldable electronic device (a magnet protruding from the housing will push against the flexible screen, causing abnormal screen display, while a magnet recessed will result in insufficient locking force, affecting the opening and closing experience of the foldable device).

[0079] For example, in some scenarios, it is necessary to keep the magnet 24 flush with the housing (the side of the housing with the assembly slot 211, such as the side of the housing facing the flexible display screen). That is, when the magnet 24 is flush with the slot of the assembly slot 211, it is difficult to control the height position of the magnet 24 (the height of the magnet in the z-direction), which makes it difficult for the magnet 24 to be flush with the housing and thus affects the performance of the foldable electronic device.

[0080] Figure 3 This is a schematic diagram illustrating a recessed step between a magnet and a housing, provided as an embodiment of this application. Figure 4 This is a schematic diagram showing a raised step between a magnet and a housing, provided as an embodiment of this application.

[0081] For example, see Figure 3 As shown, when the magnet 24 in the assembly groove 211 is too low relative to the first housing 201 in the z-direction, the magnet 24 is recessed within the assembly groove 211, forming a recessed step with a height of d1 between the magnet 24 and the first housing 201, as shown in the figure. When the first housing 201 and the second housing 202 are folded to close the foldable phone 200, the distance between the magnets 24 on the first housing 201 and the second housing 202 increases, which may result in insufficient magnetic attraction between the magnets 24. This prevents the foldable phone 200 from closing properly, affecting its stability and user experience.

[0082] See Figure 4 As shown, when the magnet 24 is too high relative to the first housing 201 in the z-direction, causing the magnet 24 to protrude beyond the assembly groove 211 and the first housing 201, a protrusion with a height of d2 is formed between the magnet 24 and the first housing 201, as shown in the figure. The magnet 24 pressing against the flexible display screen may cause insufficient light and shadow on the flexible display screen, and may even damage the flexible display screen, reducing the display stability of the foldable phone 200.

[0083] Of course, in other scenarios, a predetermined recessed step is required between the magnet 24 and the housing, such as when the recessed step is left to accommodate other structural components within the electronic device. However, because the height of the magnet 24 relative to the housing is difficult to control, an excessively large recessed step can increase the distance between the magnets 24 on the two housings, resulting in insufficient magnetic attraction. Conversely, an excessively small recessed step may affect the display performance of the flexible display screen.

[0084] Alternatively, a predetermined raised step may be required between the magnet 24 and the housing, such as when a raised step is provided to further reduce the distance between the magnets 24 on the two housings. Since the height of the magnet 24 relative to the housing is difficult to control, an excessively large raised step can affect the display performance of the flexible display. Conversely, an excessively small raised step will reduce the magnetic attraction between the magnets 24 on the two housings.

[0085] Figure 5 This is a schematic diagram illustrating the assembly of a magnet and a housing in one scenario, as provided in an embodiment of this application. Figure 6 This is a schematic diagram illustrating the assembly of the magnet and the housing in another scenario provided by an embodiment of this application. Figure 7 This is a schematic diagram illustrating the assembly of the magnet and the housing in yet another scenario provided in this application embodiment. Figure 8 This is a schematic diagram illustrating the assembly of the magnet and the housing in yet another scenario provided in this application embodiment. Figure 9 This is a schematic diagram of the assembly of the magnet and the housing in another scenario provided in the embodiments of this application.

[0086] The reasons why the height position of the magnet 24 relative to the housing is difficult to control may be due to the different sizes of the magnet 24, the different depths of the assembly slots 211 opened on the housing, and the different thicknesses of the adhesive layer 25 formed due to improper amount of adhesive, or other reasons.

[0087] Specifically, taking the first housing 201 as an example, if the amount of adhesive applied is different, that is, the thickness (thickness in the z-direction) of the resulting adhesive layer 25 is different, such as... Figure 5 As shown, when the amount of adhesive is large and the resulting adhesive layer 25 is thick, a raised step is easily formed between the magnet 24 and the first housing 201. For example... Figure 6 As shown, when the amount of adhesive is small and the adhesive layer 25 is thin, a recessed step is easily formed between the magnet 24 and the first housing 201.

[0088] Alternatively, if the magnets 24 are of different sizes, it may also cause raised or recessed steps between the magnets 24 and the first housing 201 (see reference). Figure 3 and Figure 4 (As shown). Or, if the depth of the assembly groove 211 on the first housing 201 is not uniform, such as... Figure 7 As shown, when the assembly groove 211 is shallow, it cannot fully accommodate the magnet 24, and a raised step difference easily forms between the magnet 24 and the first housing 201. Conversely, as... Figure 8 As shown, when the assembly groove 211 is deep, the magnet 24 is recessed into the assembly groove 211, and a recessed step difference is easily formed between the magnet 24 and the first housing 201.

[0089] Or, such as Figure 9As shown, during the process of colloid molding in the assembly groove 211, due to the gravity of the magnet 24 itself, the magnet 24 may continuously move towards the bottom of the assembly groove 211, causing the magnet 24 to penetrate too deeply into the assembly groove 211, making it easy to form a groove step difference between the magnet 24 and the first housing 201.

[0090] In the aforementioned magnet assembly method, the defect rate of the recessed or raised step difference between the magnet and the shell is as high as 30%, resulting in a low magnet assembly yield. To ensure the performance of foldable electronic devices, reworked magnets need to be reassembled to adjust the height position between the magnet and the shell, i.e., the step difference, so as to control it within a reasonable range. This results in a huge waste of costs and also greatly affects the assembly efficiency of electronic devices.

[0091] Based on this, embodiments of this application provide a magnet assembly apparatus and a magnet assembly method, which can accurately determine the height position of the magnet, so as to more precisely control the position of the magnet relative to the housing, thereby effectively improving the yield of magnet assembly and improving the assembly efficiency of electronic devices.

[0092] The magnet assembly apparatus and magnet assembly method provided in this application embodiment will be described in detail below with reference to specific scenarios.

Figure 11 This is a schematic diagram of the structure of a base provided in an embodiment of this application. Figure 12 This is a schematic diagram of the assembly of a base and a housing provided in an embodiment of this application. Figure 13 for Figure 10 A schematic diagram of the cross-sectional structure along plane AA in the middle. Figure 14 for Figure 10 A schematic diagram of the cross-sectional structure along the BB plane. Figure 15 This is an assembly diagram of a magnetic component, a second cover plate, and a magnet, provided for an embodiment of this application.

[0095] See Figure 10 As shown in the figure, a magnet assembly device 100 provided in this application embodiment includes a base 10, a first cover plate 20 and a second cover plate 30, wherein the first cover plate 20 and the second cover plate 30 are respectively disposed on the base 10.

[0096] The base 10 is used to support the housing of the electronic device. In this embodiment, taking the first housing 201 as an example, as follows... Figure 10 As shown, during the assembly process, the first housing 201 is mounted on the base 10.

[0097] For details, see Figure 11As shown, the base 10 may have a protruding support platform 11, and the first housing 201 may have a receiving cavity, into which the support platform 11 extends (see reference). Figure 13 As shown), and abuts against the first housing 201 to support the first housing 201, restricting the movement of the first housing 201 in the z direction, so that the first housing 201 can be mounted on the base 10.

[0098] See also Figure 11 As shown, a first limiting member 111 can be provided on the support platform 11, and a second limiting member (not shown in the figure) can be provided on the first housing 201, in combination with... Figure 12 As shown, when the first housing 201 is placed on the support platform 11 of the base 10, the first limiting member 111 and the second limiting member cooperate to limit the first housing 201 in the x-direction (width direction of the electronic device) and y-direction (length direction of the electronic device), thus fixing the first housing 201 to the base 10. This prevents the first housing 201 from moving during the assembly of the magnet 24, which helps to improve the accuracy of the magnet 24 assembly and increase the assembly yield.

[0099] Specifically, the first limiting member 111 can be formed on the side of the support platform 11 facing the housing. The first limiting member 111 is a limiting post protruding away from the base 10. The second limiting member can be a limiting hole opened on the first housing 201. The limiting post can extend into the limiting hole and cooperate with the limiting hole to achieve limiting.

[0100] The first cover plate 20 and the second cover plate 30 are used to press onto the housing. For details, see [link to details]. Figure 13 As shown, the first cover plate 20 and the second cover plate 30 are respectively pressed onto the side of the first housing 201 facing away from the base 10. The second cover plate 30 is pressed onto the end of the first housing 201 where the magnet 24 is disposed. The first cover plate 20 can fix the first housing 201, so as to further prevent the first housing 201 from shaking or moving, and further improve the accuracy of the assembly of the magnet 24.

[0101] Among them, such as Figure 13 As shown, the first cover plate 20 and the second cover plate 30 can be located on opposite sides of the base 10, so that the first cover plate 20 and the second cover plate 30 are arranged opposite each other. When the first cover plate 20 and the second cover plate 30 are pressed on the first housing 201, they can be pressed on opposite ends of the first housing 201, that is, the second cover plate 30 is pressed on the end of the first housing 201 where the magnet 24 is provided, and the first cover plate 20 is pressed on the opposite end of the first housing 201, which helps to further enhance the fixing effect on the first housing 201.

[0102] Alternatively, the first cover plate 20 and the second cover plate 30 can be located on the same side of the base 10, so that the first cover plate 20 and the second cover plate 30 press against the same side of the first housing 201. Alternatively, the first cover plate 20 and the second cover plate 30 can also be located on adjacent sides of the base 10, so that the first cover plate 20 and the second cover plate 30 press against adjacent sides of the first housing 201. Specifically, the relative positions of the first cover plate 20 and the second cover plate 30 are not limited in this embodiment.

[0103] After the first housing 201 is placed on the base 10, the first cover plate 20 can be pressed onto the first housing 201 first, then glue can be applied to the assembly groove on the first housing 201, and the magnet 24 can be placed in the assembly groove. Then the second cover plate 30 can be pressed onto the first housing 201.

[0104] Taking the magnet assembly device 100 for assembling the magnet 24 onto the housing, so that the magnet 24 is flush with the plane of the housing (the side of the housing facing the flexible display screen) as an example.

[0105] See Figure 14 As shown, when the second cover plate 30 is pressed onto the first housing 201, the second cover plate 30 covers at least a portion of the magnet 24, that is, the side of the second cover plate 30 facing the first housing 201 is in contact with the side of the first housing 201 facing the second cover plate 30, and the second cover plate 30 covers at least a portion of the magnet 24, that is, the projection of the magnet in the z-direction at least partially coincides with the second cover plate 30.

[0106] Combination Figure 15 As shown, taking the second cover plate 30 pressed onto the first housing 201, with the second cover plate 30 completely covering the magnet 24 as an example, that is, part of the second cover plate 30 is pressed onto the first housing 201, and part of the second cover plate 30 covers the magnet 24. A magnetic element 40 is also provided on the side of the second cover plate 30 facing away from the base 10, that is, the magnetic element 40 is provided on the side of the second cover plate 30 facing away from the first housing 201, and the magnetic element 40 and the magnet 24 attract each other.

[0107] In other words, when the second cover plate 30 is pressed onto the first housing 201, part of the second cover plate 30 contacts the plane of the first housing 201, and under the magnetic attraction of the magnetic component 40, part of the second cover plate 30 will contact the magnet 24, thereby keeping the magnet 24 flush with the plane of the first housing 201, eliminating the step difference between the magnet 24 and the first housing 201, accurately fixing the height of the magnet 24 in the z-direction, and improving the assembly yield of the magnet 24.

[0108] For example, when the magnet 24 is placed in the assembly groove 211, a raised step difference is formed between the magnet 24 and the first housing 201. The pressing and squeezing action of the second cover plate 30 on the magnet 24 can make the magnet 24 move toward the bottom of the assembly groove 211 of the first housing 201, thereby reducing or eliminating the raised step difference and making the magnet 24 flush with the first housing 201.

[0109] Meanwhile, due to the mutual attraction between the magnetic component 40 and the magnet 24, and with part of the second cover plate 30 pressing against the first housing 201, there is no gap between the second cover plate 30 and the plane of the first housing 201. Part of the second cover plate 30 presses against the magnet 24. When the magnet 24 moves excessively towards the bottom of the assembly groove 211 under the influence of gravity, the magnetic component 40 can hold the magnet 24, ensuring a gapless contact between the magnet 24 and the second cover plate 30. This keeps the magnet 24 flush with the plane of the first housing 201 (the side of the first housing 201 with the assembly groove 211, i.e., the side of the first housing 201 facing the second cover plate 30). This effectively controls the height of the magnet 24, keeping it flush with the plane of the first housing 201, thus improving the assembly yield of the magnet 24, avoiding disassembly and rework, and increasing the assembly efficiency of electronic devices.

[0110] When magnet 24 is placed in assembly slot 211, a recessed step is formed between magnet 24 and first housing 201. Second cover plate 30 is pressed onto first housing 201, and magnetic component 40 is placed on second cover plate 30. Because second cover plate 30 is pressed onto first housing 201, there is no gap between the side of second cover plate 30 facing first housing 201 and the plane of first housing 201. Magnetic component 40 attracts magnet 24, causing it to move towards second cover plate 30, ultimately making contact between magnet 24 and the plane of second cover plate 30 facing first housing 201 without gap. This keeps magnet 24 flush with the plane of first housing 201, adjusting the height of magnet 24, eliminating the recessed step between magnet 24 and first housing 201, and improving the assembly yield of magnet 24.

[0111] In the embodiments of this application, see Figure 14 As shown, the second cover plate 30 has a pressing boss 31 on the side facing the base 10. Part of the pressing boss 31 presses onto the first housing 201, and part of the pressing boss 31 presses onto the magnet 24. Thus, when the second cover plate 30 presses onto the first housing 201, the pressing boss 31 on the second cover plate 30 contacts the first housing 201, meaning that the side of the pressing boss 31 facing away from the second cover plate 30 contacts the plane of the first housing 201 without gap. The side of the pressing boss 31 facing away from the second cover plate 30 contacts the magnet 24 without gap, thereby ensuring that the magnet 24 and the first housing 201 are flush.

[0112] The area of ​​the pressing boss 31 facing away from the second cover plate 30 is smaller than the area of ​​the second cover plate 30 facing the base 10. Compared with the second cover plate 30 directly pressing against the first housing 201, the use of the smaller pressing boss 31 to contact the first housing 201 can reduce or avoid the influence of the different plane height of the first housing 201 on the height position of the magnet 24. This further improves the flatness of the magnet 24 and the first housing 201 around the assembly groove 211, reduces the impact of the step difference between the magnet 24 and the first housing 201 on the electronic device, and helps to improve the assembly yield of the magnet 24.

[0113] Combination Figure 13 and Figure 14 As shown, the magnet assembly device 100 may also include a first mounting member 60, one end of the first cover plate 20 is mounted on the base 10 through the first mounting member 60, and the other end of the first cover plate 20 is pressed onto the first housing 201.

[0114] The first mounting component 60 can be a columnar support, or it can be other forms of support structure. The first mounting component 60 and the base 10 can be integrally formed, or the first mounting component 60 can be set on the base 10 by means of thread fastening, snap-fit, or other methods.

[0115] It should be noted that when using the assembly device 100, the first housing 201 is first placed on the support platform 11, and then the first cover plate 20 is pressed onto the first housing 201, with one end of the first cover plate 20 located on the first mounting member 60. The first cover plate 20 and the first mounting member 60 can be connected.

[0116] Specifically, one end of the first cover plate 20 can be connected to the first mounting component 60 by fasteners such as screws and bolts. For example, a first threaded hole and a second threaded hole are respectively provided on the first mounting component 60 and the first cover plate 20. After the first housing 201 is placed on the support, the fastener passes through the second threaded hole and cooperates with the first threaded hole to realize the connection between the first cover plate 20 and the mounting component.

[0117] Alternatively, the first cover plate 20 can be rotatably connected to the first mounting member 60, allowing the first cover plate 20 to rotate relative to the first mounting member 60 towards or away from the support platform 11 (e.g., Figure 14In this process, the first cover plate 20 is rotated relative to the first mounting member 60 about a direction perpendicular to the plane of the paper. When it is necessary to place the first housing 201 on the support platform 11, the first cover plate 20 is rotated so that it rotates away from the support platform 11, exposing the support platform 11, thereby placing the first housing 201 on the support platform 11. Then, the first cover plate 20 is rotated in the opposite direction so that it rotates towards the support platform 11, so that the first cover plate 20 presses against the first housing 201.

[0118] Alternatively, the first cover plate 20 and the first mounting member 60 may be connected in other ways, which are not limited in this embodiment.

[0119] To ensure that the first cover plate 20 effectively presses and fixes the first housing 201, the area of ​​the first cover plate 20 can be relatively large. Two or more first mounting members 60 can be provided on the base 10. For example, two opposing first mounting members 60 can be provided on the base 10 (see reference). Figure 14 As shown, the first cover plate 20 is supported and fixed by two first mounting parts 60, which can provide good support for the first cover plate 20.

[0120] It should be noted that the second cover plate 30 has a relatively large area. When the second cover plate 30 is placed on the first housing 201, it covers the corresponding position of the first limiting member 111. Therefore, in order to avoid the first limiting member 111 and ensure that the second cover plate 30 can make good contact with the housing and there is no gap between the second cover plate 30 and the housing, an avoidance hole 21 can be provided on the second cover plate 30 (see reference). Figure 20 As shown), the first limiting member 111 extends into the clearance hole 21.

[0121] The magnet assembly device 100 may further include a second mounting member 70, as shown in the figure. Figure 13 As shown, one end of the second cover plate 30 is mounted on the base 10 via the second mounting member 70, and the other end of the second cover plate 30 is pressed onto the housing.

[0122] Correspondingly, the second mounting component 70 can also be a columnar support platform 11, or it can be other forms of support structure. The second mounting component 70 can also be integrally formed with the support platform 11, or it can be set on the support platform 11 by means of thread fastening, snap-fit, or other methods.

[0123] Similarly, when using the assembly device 100, after the first cover plate 20 is pressed onto the first housing 201, the second cover plate 30 is pressed onto the first housing 201, with one end of the second cover plate 30 located on the second mounting member 70.

[0124] The area of ​​the second cover plate 30 can be relatively smaller than that of the first cover plate 20 to reduce the contact area between the second cover plate 30 and the first housing 201, thereby reducing or avoiding the step difference between the magnet 24 and the first housing 201 caused by the unevenness of the plane of the first housing 201, and further improving the assembly accuracy of the magnet 24.

[0125] The second cover plate 30 can be placed on the second mounting member 70 without being connected to the second mounting member 70, or the second cover plate 30 can be connected to the second mounting member 70 to ensure the stability of the second cover plate 30 and further improve the yield of the magnet 24 assembly.

[0126] The second cover plate 30 can also be connected to the second mounting member 70 using fasteners such as screws or bolts. Alternatively, the second cover plate 30 can be rotatably connected to the second mounting member 70, allowing the second cover plate 30 to rotate relative to the second mounting member 70 towards or away from the support platform 11. Other connection methods between the second cover plate 30 and the second mounting member 70 are also possible and are not limited in this embodiment.

[0127] Figure 16 This is a schematic diagram of the assembly of the second cover plate and the housing in another magnet assembly device provided in an embodiment of this application.

[0128] In one possible implementation, see Figure 16 As shown, the second cover plate 30 can be a deformable component, meaning that the second cover plate 30 can deform under a certain force. Specifically, the magnet 24 assembly device 100 may also include a controller, which is used to control the magnetic component 40. Specifically, the controller can change the magnetic attraction between the magnetic component 40 and the magnet 24 by controlling the state of the magnetic component 40, that is, it can adjust the magnitude of the magnetic force between the magnetic component 40 and the magnet 24.

[0129] If it is necessary to keep the magnet 24 flush with the plane of the first housing 201, the controller can control the magnetic component 40 to adjust the magnetic attraction between the magnetic component 40 and the magnet 24. The second cover plate 30 will not deform under the action of the magnetic attraction, that is, the side of the second cover plate 30 facing the base 10 remains flat. The second cover plate 30 is pressed on the housing and covers the magnet 24.

[0130] When the magnet 24 is placed (i.e. before the second cover plate 30 is placed), there is a raised step difference between it and the first housing 201. The pressing and squeezing of the second cover plate 30 can reduce or eliminate this raised step difference. At the same time, the magnetic attraction between the magnetic component 40 and the magnet 24 can also keep the magnet 24 from moving too much toward the bottom of the assembly groove 211, accurately control the z-axis height of the magnet 24, and ensure that the magnet 24 is flush with the plane of the first housing 201.

[0131] When the magnet 24 is placed, there is a recessed step between it and the first housing 201. Part of the second cover plate 30 is pressed onto the first housing 201 and has no gap in contact with the plane of the first housing 201. Part of the second cover plate 30 covers the magnet 24. The magnet attracts the magnet 24 to contact the second cover plate 30 without gap, and precisely fixes the z-axis height of the magnet 24, thereby ensuring that the magnet 24 is flush with the plane of the first housing 201.

[0132] If a certain range of recessed step difference is required between the magnet 24 and the first housing 201, the controller can control the magnet to adjust the magnetic attraction between the magnet and the magnet 24, so that the second cover plate 30 is deformed under the action of the magnetic attraction, and the side of the second cover plate 30 facing the first housing 201 is deformed to form a protrusion, which extends into the assembly groove 211.

[0133] In this way, the second cover plate 30 is pressed onto the first housing 201, and the protrusion extends into the assembly groove 211. The force between the magnetic component 40 and the magnet 24, or the squeezing force of the protrusion on the magnet 24, will eventually cause the magnet 24 to abut against the protrusion. That is, there is no gap between the second cover plate 30 and the plane of the first housing 201, and the protrusion on the second cover plate 30 extends into the assembly groove 211 to contact the magnet 24. Thus, the thickness of the protrusion in the z-direction is the distance between the plane of the magnet 24 and the first housing 201, that is, the recessed step difference formed between the magnet 24 and the first housing 201. The thickness of the protrusion can be precisely controlled, which achieves precise fixation of the height of the magnet 24 in the z-direction, so that the recessed step difference between the magnet 24 and the first housing 201 is the preset recessed step difference, effectively improving the assembly yield of the magnet 24.

[0134] If a certain numerical range of protrusion difference is required between magnet 24 and the first housing 201, the controller can control the magnet to adjust the magnetic attraction between the magnet and magnet 24. For example, by increasing the magnetic attraction of the magnet on magnet 24, magnet 24 will move toward the second cover plate 30, causing the second cover plate 30 to deform. That is, a groove will be formed on the side of the second cover plate 30 facing the first housing 201, and magnet 24 will extend into the groove.

[0135] After the second cover plate 30 is pressed onto the first housing 201, the magnet 24 moves toward the second cover plate 30 under the action of the magnetic component 40, causing the second cover plate 30 to deform inward. Since the second cover plate 30 contacts the first housing 201 without gaps, the magnet 24 protrudes from the first housing 201, creating a raised step between them. The magnetic attraction between the magnetic component 40 and the magnet 24 can be controlled relatively precisely, thus accurately controlling the movement position of the magnet 24, i.e., controlling its z-axis height position, thereby achieving precise control of the raised step between the magnet 24 and the first housing 201.

[0136] By making the second cover plate 30 a deformable component, the assembly device 100 can be adapted to different scenario requirements to accurately fix the height of the magnet 24 in the z-direction, effectively improving the applicability of the assembly device 100.

[0137] Figure 17 This is a schematic flowchart of a magnet assembly method provided in an embodiment of this application. Figure 18 This is a cross-sectional structural diagram of a base and a housing provided in an embodiment of this application. Figure 19 This is a schematic diagram of a structure in which a first cover plate is attached to a housing, according to an embodiment of this application. Figure 20 This is a cross-sectional structural diagram of a first cover plate being installed on a housing, according to an embodiment of this application. Figure 21 This is a schematic diagram of a structure in which a second cover plate is attached to a housing, according to an embodiment of this application. Figure 22 This is a cross-sectional structural diagram of a second cover plate covering the housing, provided in an embodiment of this application.

[0138] This application also provides a magnet assembly method, in which the magnet 24 is assembled onto the housing of an electronic device using the magnet assembly device 100 described above.

[0139] For details, see Figure 17 As shown, the method includes:

[0140] S101: The housing of the electronic device is mounted on the base.

[0141] See Figure 18 As shown, the first housing 201 is mounted on the support platform 11 of the base 10. The support platform 11 extends into the first housing 201 and abuts against and supports the first housing 201. The first limiting member 111 on the support platform 11 cooperates with the second limiting member of the first housing 201 to limit the first housing 201 in the x, y, and z directions, thereby fixing the first housing 201 on the base 10.

[0142] S102: Press the first cover plate onto the side of the housing facing away from the base.

[0143] See Figure 19 and Figure 20 As shown, one end of the first cover plate 20 is located on the first mounting member 60, and the other end of the first cover plate 20 is pressed against the first housing 201, wherein the end of the first cover plate 20 pressed against the first housing 201 is away from the assembly groove 211. See also Figure 20 As shown, the first cover plate 20 has a clearance hole 21 to avoid the first limiting member 111.

[0144] S103: Apply adhesive to the assembly slot of the housing and place the magnet.

[0145] After the first housing 201 is placed on the base 10 and the first cover plate 20 is pressed on, glue is applied to the assembly groove 211 of the first housing 201, and then the magnet 24 is placed in the magnet 24 groove.

[0146] S104: Press the second cover plate onto the side of the housing facing away from the base, and press the second cover plate onto the end of the housing where the magnet is located, and the second cover plate at least covers part of the magnet.

[0147] See Figure 21 and Figure 22 As shown, after placing the magnet 24, the second cover plate 30 is pressed onto the first housing 201. Specifically, the side of the second cover plate 30 facing the base 10 contacts the side of the first housing 201 facing away from the base 10, and the second cover plate 30 covers at least part of the magnet 24 so that part of the second cover plate 30 contacts the plane of the first housing 201, and part of the second cover plate 30 covers the magnet 24.

[0148] When the second cover plate 30 has a pressing boss 31 on the side facing the base 10, the second cover plate 30 is pressed onto the first housing 201, part of the pressing boss 31 is pressed onto the first housing 201, and part of the pressing boss 31 is pressed onto the magnet 24.

[0149] S103: The magnetic component is placed on the side of the second cover plate facing away from the base, so that the magnetic component attracts the magnet.

[0150] See Figure 23 As shown, the magnetic component 40 is placed on the second cover plate 30 and is attracted to the magnet 24. The attraction between the magnetic component 40 and the magnet 24 ensures the precise positioning of the magnet 24 in the z-direction.

[0151] In addition, by pressing the second cover plate 30 onto the first housing 201 and then placing the magnetic component 40 on the second cover plate 30, compared to placing the magnetic component 40 and the second cover plate 30 simultaneously, it is possible to prevent the magnet 24 from being pulled up too early, which would cause the magnet 24 to leave the assembly slot 211 without making good contact with the dispensing adhesive, thus helping to improve assembly efficiency.

[0152] S104: After standing, remove the magnetic component, the second cover plate, and the first cover plate from the housing in sequence.

[0153] Specifically, the settling time can be selected and set according to the characteristics of the adhesive used for dispensing. For example, it can be set for 30-120 minutes to allow the adhesive to cure. After that, the magnetic component 40 can be removed, the second cover plate 30 can be opened, and the first housing 201 with the assembled magnet 24 can be removed to complete the assembly of the magnet 24.

[0154] Figure 24 This is a schematic diagram of the assembly process of a magnet and a housing provided in an embodiment of this application.

[0155] Taking the assembly of magnet 24 on the first housing 201 as an example, see Figure 24 As shown, an assembly groove 211 is first formed on the first housing 201. The assembly groove 211 can be formed on the first housing 201 by computer number control (CNC) machining process, or the assembly groove 211 can be formed by other means.

[0156] When forming the assembly groove 211, support blocks 213 can be formed on opposite sides inside the assembly groove 211.

[0157] Then, the first housing 201 is placed on the base 10, and the first cover plate 20 is pressed onto the first housing 201. Adhesive is applied in the assembly groove 211 of the first housing 201. The adhesive can be placed between two support blocks 213. The two support blocks 213 can limit the adhesive, reduce the flow of adhesive during the compression of the magnet 24, thereby reducing the adhesion performance and improving the stability of the magnet 24.

[0158] The thickness of the support block 213 can be 0.05-0.15mm, which can effectively limit the position of the colloid and further ensure the bonding strength.

[0159] Then, the second cover plate 30 is pressed onto the end of the first housing 201 with the magnet 24, and the second cover plate 30 covers the magnet 24. That is, part of the second cover plate 30 is pressed onto the first housing 201 and contacts the plane of the first housing 201, and part of the second cover plate 30 covers the magnet 24.

[0160] Finally, the magnetic component 40 is placed on the second cover plate 30. After standing for 30-120 minutes, the magnetic component 40 is removed, and the first cover plate 20 and the second cover plate 30 are opened to obtain the first housing 201 assembled with the magnet 24.

[0161] Scene 2

[0162] Figure 25 Another magnet assembly apparatus provided in the embodiments of this application.

[0163] In this scenario, a predetermined recessed step is required between the magnet 24 and the first housing 201. Unlike scenario one, see [link to scenario]. Figure 25 As shown, a pressure block 50 is provided on the side of the second cover plate 30 facing the base 10. When the second cover plate 30 is pressed onto the first housing 201, the pressure block 50 extends into the assembly groove 211 on the first housing 201. Similarly, a magnetic element 40 is provided on the second cover plate 30.

[0164] When the second cover plate 30 is pressed onto the first housing 201 and the pressure block 50 extends into the assembly groove 211, the force between the magnetic component 40 and the magnet 24, or the squeezing force of the pressure block 50 on the magnet 24, will ultimately cause the magnet 24 to come into contact with the pressure block 50. This means the second cover plate 30 and the first housing 201 have a seamless planar contact, and the pressure block 50 on the second cover plate 30 extends into the assembly groove 211 to contact the magnet 24. The thickness of the pressure block 50 in the z-direction is the distance between the magnet 24 and the plane of the first housing 201, forming a recessed step between the magnet 24 and the first housing 201. The thickness of the pressure block 50 can be precisely controlled, thus achieving precise fixation of the magnet 24's height in the z-direction, ensuring the recessed step between the magnet 24 and the first housing 201 is a preset recessed step, effectively improving the assembly yield of the magnet 24.

[0165] For example, after the magnet 24 is placed in the assembly slot 211, if there is a recessed step difference between the magnet 24 and the first housing 201, and this recessed step difference is relatively large compared to the preset recessed step difference, the magnet can attract the magnet 24 to move towards the second cover plate 30, and eventually make the magnet 24 abut against the pressure block 50. Since there is no gap between the second cover plate 30 and the first housing 201, the pressure block 50 extends into the assembly slot 211 and abuts against the magnet 24. The thickness of the pressure block 50 is the distance difference between the plane of the magnet 24 and the first housing 201, thus forming the preset recessed step difference between the magnet 24 and the first housing 201. The height of the pressure block 50 can be controlled more precisely, thus achieving precise fixation of the z-axis height of the magnet 24. This enables precise control of the recessed step difference between the magnet 24 and the first housing 201, improving the assembly yield of the magnet 24.

[0166] When the magnet 24 is placed flush with the first housing 201, or has a raised step, or has a recessed step that is smaller than the preset recessed step, the pressure block 50 extends into the assembly groove 211 when the second cover plate 30 is pressed on the first housing 201. In this way, the pressure block 50 can press and squeeze the magnet 24, causing the magnet 24 to move toward the bottom of the assembly groove 211 and eventually recess into the assembly groove 211. A preset recessed step is formed between the magnet 24 and the first housing 201. Similarly, the height of the pressure block 50 can be precisely controlled, thereby achieving precise control of the recessed step between the magnet 24 and the first housing 201.

[0167] The pressure block 50 can be integrally formed on the side of the second cover plate 30 facing the housing during the forming of the second cover plate 30. Alternatively, the pressure block can be formed separately from the second cover plate 30 and then attached to the second cover plate 30 by means of threaded connection, bonding, or snap-fit.

[0168] It should be noted that, in the embodiments of this application, when the assembly device 100 is used to assemble the magnet 24 onto the housing of the electronic device, taking the first housing 201 as an example, in step S104, the second cover plate 30 is pressed onto the side of the housing facing away from the base 10, and the second cover plate 30 is pressed onto the end of the housing where the magnet 24 is provided. Specifically, the pressing block 50 on the second cover plate 30 extends into the assembly groove 211.

[0169] Scene 3

[0170] Figure 26 This application provides yet another magnet assembly apparatus.

[0171] In this scenario, we take the example of a pre-defined raised step between the magnet 24 and the first housing 201. Unlike scenario one, the second cover plate 30 has a recessed clearance groove 32 on the side facing the base 10, which is used to avoid the magnet 24.

[0172] For details, see Figure 26 As shown, the second cover plate 30, facing the base 10 (i.e., the side facing the first housing 201), has a recessed clearance groove 32 towards the magnetic component 40. When the second cover plate 30 is pressed onto the first housing 201, the magnet 24 extends into the clearance groove 32 under the action of the magnetic component 40 and contacts the first housing 201. Because the clearance groove 32 is recessed, the magnet 24 extends beyond the mounting groove 211, protruding from the first housing 201, creating a raised step difference between the magnet 24 and the first housing 201. The depth of the clearance groove 32 can be precisely controlled, thereby accurately fixing the magnet 24 in the required position and achieving precise control of the raised step difference between the magnet 24 and the first housing 201.

[0173] For example, after the magnet 24 is placed in the assembly slot 211, if there is a recessed step difference between the magnet 24 and the first housing 201, or a raised step difference, but the raised step difference is smaller than the preset raised step difference, or is flush, after the second cover plate 30 is pressed on the first housing 201, the magnet 24 will move toward the second cover plate 30 under the magnetic attraction of the magnetic component 40, so that the magnet 24 extends into the relief slot 32 and comes into contact with the second housing 202, so that the magnet 24 and the first housing 201 form a preset raised step difference.

[0174] When the magnet 24 is placed, if there is a raised step difference between the magnet 24 and the first housing 201, and the raised step difference is greater than the preset raised step difference, after the second cover plate 30 is pressed on the first housing 201, the magnet 24 is in the relief groove 32 and abuts against the bottom of the groove. Under the extrusion force of the second cover plate 30, the magnet 24 moves toward the assembly groove 211, and the magnet 24 is attracted to the magnetic component 40, so that a preset recessed step difference is formed between the magnet 24 and the first housing 201.

[0175] The clearance groove 32 can be formed integrally with the second cover plate 30 by recessing it on the side of the second cover plate 30 facing the shell during the forming of the second cover plate 30.

[0176] It should be noted that, in the embodiments of this application, when the assembly device 100 is used to assemble the magnet 24 onto the housing of the electronic device, taking the first housing 201 as an example, in step S104, the second cover plate 30 is pressed onto the side of the housing facing away from the base 10, and the second cover plate 30 is pressed onto the end of the housing where the magnet 24 is provided. Specifically, the clearance groove 32 on the second cover plate 30 is positioned opposite to the magnet 24 to ensure that the magnet 24 can extend into the clearance groove 32.
