[0035] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0036] To meet user needs, some current electronic devices have metal contacts on their casings for charging or data transfer with other compatible electronic devices. The electronic devices involved in this disclosure can also be called terminal devices, user equipment (UE), mobile stations (MS), mobile terminals (MT), etc., and are devices that provide voice and / or data connectivity to users. For example, electronic devices can be handheld devices with wireless connectivity, in-vehicle devices, etc. Examples of current electronic devices include: smartphones (Mobile Phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices. Furthermore, when it is a vehicle-to-everything (V2X) communication system, the electronic device can also be an in-vehicle device. It should be understood that the embodiments of this disclosure do not limit the specific technologies or device forms used in the electronic devices.

[0037] Figure 1 This is a structural schematic diagram of product 1 to be welded. Figure 2This is a schematic diagram of welding product 1 in related technologies, such as... Figure 1 and Figure 2 As shown, in related technologies, when assembling an electronic device with this function, the conductive component 12 is first inserted through the outer casing 11 of the product, i.e., the outer casing 11 of the product 1 to be welded. One end of the conductive component 12 is located inside the outer casing 11 and is used to make an electrical connection with the circuit board 13 inside the outer casing 11 by welding. The other end of the conductive component 12 forms a metal contact of the outer casing 11. Then, the outer casing 11 of the product is placed on the fixture 2, and the end of the conductive component located inside the outer casing 11 is welded to the circuit board 13 by the welding equipment 3. However, in related technologies, when welding the conductive component 12 and the circuit board 13, the fixture 2 only positions and limits the outer casing 11 of the product, but does not limit the conductive component 12 installed on the outer casing 11. During welding, due to the feeding of the welding equipment 3, the installation position of the conductive component 12 on the outer casing 11 is easily misaligned, resulting in poor welding effect.

[0038] To solve the above-mentioned technical problems, this disclosure provides a welding fixture, which uses a support column 61 to limit the conductive component 12, so as to ensure the relative position of the conductive component 12 is stable during the welding process, thereby avoiding the displacement of the installation position of the conductive component 12 on the housing 11 during the welding process.

[0039] Figure 3 This is a schematic diagram illustrating the structure of a welding fixture according to an exemplary embodiment. Figure 4 yes Figure 3 A magnified view of a portion of point A in the middle. Figure 5 yes Figure 3 Top view at point A, as shown Figure 3 , Figure 4 and Figure 5 As shown, the welding fixture includes: a mounting platform 4; a support portion 5, disposed on the mounting platform 4 and used to place the product 1 to be welded; and a limiting portion 6, movably connected to the mounting platform 4. The limiting portion 6 is provided with a support column 61, one end of which protrudes from the limiting portion 6 and faces the support portion 5. When the limiting portion 6 moves to a preset position, the protruding end of the support column 61 abuts against the conductive component 12 of the product 1 to be welded.

[0040] The mounting platform 4 provides a mounting base for other components of the welding fixture in this embodiment, and facilitates the installation of the welding fixture of this embodiment onto the suitable welding equipment 3. Before welding the conductive component 12 of the product 1 to be welded, the product 1 to be welded is placed on the support part 5, and the support part 5 positions and limits the outer shell 11 of the product 1 to be welded. Then, the limiting part 6 is moved to a preset position, so that the support column 61 provided on the limiting part 6 abuts against the conductive component 12, so as to ensure the relative position of the conductive component 12 is stable during the welding process, thereby avoiding the displacement of the installation position of the conductive component 12 on the outer shell 11 during the welding process.

[0041] In some embodiments, the limiting part 6 further includes a first elastic element 64. The support column 61 is connected to the limiting part 6 via the first elastic element 64. During the process of the limiting part 6 moving to a preset position, after the support column 61 contacts the conductive element 12, the first elastic element 64 undergoes elastic deformation to generate elastic force, thereby achieving contact between the support column 61 and the conductive element 12. That is, during the welding process, the support column 61 applies pressure to the conductive element 12 to keep the relative position of the conductive element 12 stable. Furthermore, by providing the first elastic element 64, the pressure applied by the support column 61 to the conductive element 12 is made gentler, which can ensure the squeezing effect and avoid over-pressure on the conductive element 12, which could damage the conductive element 12 or the outer shell 11 of the product 1 to be welded.

[0042] In some embodiments, the limiting part 6 further includes a cavity 65. One end of the support column 61 is located inside the cavity 65 and is connected to the inner wall of the cavity 65 through a first elastic member 64, and the other end of the support column 61 protrudes from the cavity 65 and faces the bearing part 5.

[0043] The first elastic element 64 is a compression spring. The cavity 65 facilitates the installation of the support column 61 and the first elastic element 64, and also limits the movement of the support column 61. The support column 61 can move linearly along its axis. When the protruding end of the support column 61 contacts the conductive element 12, the end of the support column 61 located inside the cavity 65 applies pressure to the compression spring, causing the compression spring to elastically deform. The elastic force generated by the compression spring allows the support column 61 to apply pressure to the conductive element 12.

[0044] Figure 6 This is a cross-sectional view of the support column mounting block 62 according to an exemplary embodiment, as shown below. Figure 6As shown, in some embodiments, the side of the support column 61 is stepped, and the diameter of the end of the support column 61 inside the cavity 65 is larger than the diameter of the end of the support column 61 protruding from the cavity 65. The inner wall of the cavity 65 matches the inner wall of the support column 61, and the stepped shape of the inner wall of the cavity 65 allows it to limit the movement of the support column 61 along its axis, and during the movement, the support column 61 will not completely move out of the cavity 65 and fall off.

[0045] like Figure 3 As shown, in some embodiments, the limiting part 6 includes a slider 63 and a support column mounting block 62. The slider 63 is slidably disposed on the mounting platform 4. The support column mounting block 62 is connected to the slider 63. Figure 6 As shown, cavity 65 is formed in support column mounting block 62. By providing slider 63, limiting part 6 can move to a preset position. Slider 63 and support column mounting block 62 are detachably connected, facilitating maintenance and replacement of slider 63 and support column mounting block 62.

[0046] In some embodiments, multiple support columns 61 are provided to accommodate multiple conductive elements 12 mounted on the outer shell 11 of the product to be welded 1. Each support column 61 corresponds to one of the conductive elements 12, and each provides abutment and limiting. The axes of the multiple support columns 61 are parallel to each other, ensuring that the relative positions of the axes of each support column 61 do not change during the movement of the limiting part 6 to a preset position. This guarantees the accurate positioning of the abutment end of each support column 61, allowing for abutment and limiting of each conductive element 12. Correspondingly, multiple first elastic elements 64 are provided, each corresponding to one of the multiple support columns 61, providing pressure to each support column 61 to prevent inconsistent abutment and ensure that one or more support columns 61 do not abut properly.

[0047] In some embodiments, the product to be soldered 1 is a true wireless stereo (TWS) earphone. For a stem-shaped TWS earphone, two conductive parts 12 are soldered to the earphone circuit board 13 at the end of the stem for charging the earphone from the charging case. Correspondingly, two support pillars 61 are provided to abut and position the two conductive parts 12.

[0048] In some embodiments, the mounting platform 4 is provided with a guide rail 41, which matches the slider 63. The slider 63 is slidably disposed on the guide rail 41, and the support column mounting block 62 is located on the side of the slider 63 away from the guide rail 41. The longitudinal direction of the guide rail 41 is parallel to the axial direction of the support column 61 to ensure accurate positioning of the support column 61 during the contact and positioning process.

[0049] In some embodiments, the support post 61 is made of a thermally conductive material. During the soldering of the conductive component 12 and the circuit board 13, high heat is generated, causing the conductive component 12 to reach a high temperature, which can easily lead to deformation or damage to the outer casing 11 of the product to be soldered. By providing the support post 61 made of thermally conductive material, the high temperature generated during soldering of the conductive component 12 is dissipated through the support post 61, thereby preventing deformation or damage to the outer casing 11 of the product to be soldered due to the high temperature of the conductive component 12.

[0050] In some exemplary embodiments, the support column 61 is made of copper.

[0051] like Figure 3 As shown, in some embodiments, the welding fixture further includes a clamping device 7. The clamping device 7 is disposed on the mounting platform 4 and is connected to the limiting part 6. The clamping device 7 is used to move the limiting part 6 to a preset position and fix the limiting part 6 in the preset position. This reduces the operational difficulty of the welding fixture and improves assembly efficiency.

[0052] In some embodiments, the limiting part 6 is located between the supporting part 5 and the clamping device 7. The mounting platform 4 has a plate-like structure, and the limiting part 6, the supporting part 5, and the clamping device 7 are all located on the same side of the mounting platform 4. The clamping device 7 drives the limiting part 6 to move towards the supporting part 5, causing the limiting part 6 to move to a preset position. At this point, the support column 61 abuts against the conductive element 12 for welding. After welding is completed, the clamping device 7 drives the limiting part 6 to move away from the supporting part 5, causing the support column 61 to move away from the conductive element 12.

[0053] In some embodiments, the clamping device 7 includes a linkage latch structure 71 and a connecting portion 72. The driving end of the linkage latch structure 71 is connected to the limiting portion 6 via the connecting portion 72. The driving end of the linkage latch structure 71 can move linearly and lock when it reaches its limit position. Therefore, by providing the linkage latch structure 71, the limiting portion 6 can be driven to slide along the guide rail 41 and locked when it slides to a preset position.

[0054] In some embodiments, the clamping device 7 further includes a second elastic member 73. The connecting portion 72 is connected to the limiting portion 6 via the second elastic member 73. During the process of the limiting portion 6 moving to the preset position, after the support column 61 contacts the conductive member 12, the second elastic member 73 undergoes elastic deformation to generate elastic force, so as to achieve the abutment between the support column 61 and the conductive member 12.

[0055] In some embodiments, the placement table 51 is provided with a plurality of positioning slots 52 for placing a plurality of products 1 to be welded. A plurality of limiting parts 6 are provided, each corresponding to one of the positioning slots 52, to abut and limit the conductive parts 12 of the corresponding products 1 to be welded. This effectively improves efficiency.

[0056] In this configuration, multiple positioning grooves 52 are arranged in a straight line, and multiple limiting parts 6 are also arranged in a straight line. The arrangement direction of the multiple positioning grooves 52 is parallel to the arrangement direction of the multiple limiting parts 6. One side of the connecting part 72 is connected to the driving end of the connecting rod pull structure 71, and the other side of the connecting part 72 is connected to the multiple limiting parts 6 through multiple second elastic elements 73, so that the connecting rod pull structure 71 can simultaneously drive the multiple limiting parts 6 through the limiting parts 6.

[0057] In some embodiments, the support portion 5 is detachably connected to the mounting platform 4. This allows the support portion 5 to be removed from the mounting platform 4, facilitating the placement or removal of the product 1 to be welded, and making it easy to replace the support portion 5 according to different products 1 to be welded.

[0058] In some embodiments, the mounting platform 4 is provided with a first positioning member. The first positioning member is used to position the support portion 5 to ensure that the relative position between the support portion 5 and the mounting platform 4 is accurate.

[0059] For example, the mounting platform 4 is provided with a positioning pin, the support part 5 is provided with a positioning hole that matches the positioning pin, and / or the mounting platform 4 is provided with a positioning hole, and the support part 5 is provided with a positioning pin that matches the positioning hole, so that the mounting platform 4 and the support part 5 are positioned by the pin hole.

[0060] In some embodiments, the support portion 5 is magnetically connected to the mounting platform 4, which is a simple connection method and easy to disassemble, thus improving assembly efficiency.

[0061] In some embodiments, the support portion 5 includes a placement platform 51. The placement platform 51 is detachably connected to the mounting platform 4. The mounting platform 4 is provided with a positioning pin, and the placement platform 51 is provided with a positioning hole that matches the positioning pin; and / or the mounting platform 4 is provided with a positioning hole, and the placement platform 51 is provided with a positioning pin that matches the positioning hole, so that the mounting platform 4 and the placement platform 51 are positioned together through the pin hole.

[0062] Figure 7 This is an exploded view of a welding fixture according to an exemplary embodiment, such as... Figure 7 As shown, the placement platform 51 has a positioning groove 52 on the side opposite to the mounting platform 4.

[0063] The positioning groove 52 is designed to match the shape of its inner wall with the outer shell 11 of the product to be welded. Positioning and limiting can be achieved by placing the product to be welded 1 in the positioning groove 52.

[0064] In some embodiments, the positioning groove 52 is provided with a first clearance notch. The first clearance notch is used to avoid the area of ​​the product 1 to be welded where the conductive element 12 is located, and the protruding end of the support column 61 faces the first clearance notch. This allows the support column 61 to pass through the first clearance notch to abut and limit the conductive element 12, or the area of ​​the product 1 to be welded where the conductive element 12 is located protrudes from the positioning groove 52 through the first clearance notch, allowing the support column 61 to abut and limit the conductive element 12.

[0065] For example, this disclosure is adapted for soldering TWS earphones. For TWS earphones in a rod shape, two conductive parts 12 are soldered to the earphone circuit board 13 at the end of the rod for charging the earphones from the charging case. During soldering, the TWS earphones are placed in the positioning groove 52, and the end of the TWS earphone rod protrudes from the positioning groove 52 through a first clearance notch.

[0066] In some embodiments, the support portion 5 includes a cover plate 53. The cover plate 53 is disposed on the side of the support portion 5 opposite to the mounting platform 4, and is used to fix the product 1 to be welded to ensure that the product 1 to be welded remains stable during the welding process. Furthermore, the cover plate 53 is provided with a second clearance notch 54, which is used to avoid the welding position of the product 1 to be welded, allowing the welding equipment 3 to weld through the second clearance notch 54 at the welding position of the product 1 to be welded.

[0067] For example, the support unit 5 also includes a cover plate 53. The cover plate 53 is disposed on the side of the placement platform 51 away from the mounting platform 4. The cover plate 53 is detachably connected to the placement platform 51. The cover plate 53 has a second clearance notch 54, which corresponds to the positioning groove 52. The second clearance notch 54 is used to avoid the welding position of the product 1 to be welded. By providing the cover plate 53, the product 1 to be welded located in the positioning groove 52 is further limited, thereby improving the stability of the product 1 to be welded during the welding process.

[0068] In some embodiments, the placement platform 51 is provided with a second positioning member. The second positioning member is used to position the cover plate 53 to ensure that the relative position between the placement platform 51 and the cover plate 53 is accurate.

[0069] For example, the placement platform 51 is provided with a positioning pin, and the cover plate 53 is provided with a positioning hole that matches the positioning pin, and / or the placement platform 51 is provided with a positioning hole, and the cover plate 53 is provided with a positioning pin that matches the positioning hole, so that the placement platform 51 and the cover plate 53 are positioned by the pin hole.

[0070] In some embodiments, the cover plate 53 is magnetically connected to the placement platform 51, which is a simple connection method and easy to disassemble, thus improving assembly efficiency.
