Description

Technical Field

[0001] This utility model relates to the field of production tooling technology, and in particular to a fixture. Background Technology

[0002] With the development of LED (Light Emitting Diode) display technology, the market demand for displays with various structures is emerging in an endless stream. Among them, due to the requirements of certain structural designs, it is often necessary to solder connectors on both sides of the same PCB (Printed Circuit Board).

[0003] Currently, the industry generally adopts a batch soldering method, that is, first arrange the required connectors on the first side of the PCB board, and after completing the soldering through high temperature furnace and other methods, arrange the required connectors on the second side of the PCB board and complete the soldering.

[0004] However, the above method often has the following problems: both the PCB board and the connectors soldered on the first side need to undergo two high-temperature reflow processes. During the soldering of the connectors on the second side, the connectors soldered on the first side are prone to deformation and bulging due to prolonged exposure to high temperatures, which can negatively impact product reliability. Furthermore, the two reflow processes require an additional step in the production line, reducing production efficiency and increasing energy consumption. Utility Model Content

[0005] The purpose of this utility model is to provide a clamp that enables the welding and fixing of a substrate to a first connector and a second connector located on opposite sides of the substrate in one step.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] According to one aspect of this application, a clamp is provided for clamping and fixing a lamp panel, the lamp panel including a substrate and a first connector and a second connector disposed on the substrate, the opposite sides of the substrate being a first surface and a second surface, the first surface being used to connect to the first connector, and the second surface being used to connect to the second connector; the clamp includes:

[0008] A base for supporting the substrate; the base is provided with a through hole, which is arranged in a corresponding manner to the area on the first surface for arranging the first connector and the area on the second surface for arranging the second connector.

[0009] A support assembly includes a support base and a support member disposed on the support base, the support base being detachably connected to the base; the position of the support member on the support base corresponds to the position of the through hole on the base, and the support member is used to abut against a first connector located on the first surface or a second connector located on the second surface, so that the first connector or the second connector is clamped between the support base and the substrate.

[0010] In some embodiments, the support base is provided with a first connector and the base is provided with a second connector. The arrangement position of the first connector on the support base corresponds to the arrangement position of the second connector on the base, and the first connector and the second connector are magnetically connected.

[0011] Both the first connector and the second connector are magnets.

[0012] In some embodiments, the support assembly further includes an elastic element capable of elastic extension and retraction, the elastic element being disposed on the support such that the end of the support can elastically contact the first connector or the second connector to be abutted.

[0013] In some embodiments, the support member passes through the support base and is movably connected to the support base;

[0014] The elastic element is sleeved on the support member, and the two ends of the elastic element are connected between the support member and the support base. When the elastic element extends and retracts in its axial direction, the support member moves relative to the support base, so that the end of the support member can elastically support the first connector or the second connector.

[0015] In some embodiments, the support base is provided with through holes;

[0016] The support member includes a support rod and a support block disposed at the end of the support rod; the support rod passes through the through hole and is movably engaged with the support seat; the surface of the support block facing away from the support rod is used to abut against the first connector or the second connector; the outer diameter of the support block is larger than the inner diameter of the through hole;

[0017] The support member further includes a limiting block disposed at the end of the support rod opposite to the support block, the limiting block and the support block being disposed at opposite ends of the support base; the outer diameter of the limiting block is larger than the inner diameter of the through hole;

[0018] The elastic element is sleeved on the support rod, and the two axial ends of the elastic element are connected between the support base and the support block, or the two axial ends of the elastic element are connected between the support base and the limiting block.

[0019] In some embodiments, the base has a first surface and a second surface on opposite sides along the axial direction of the through hole, and the inner peripheral wall of the base is recessed outward on the side near the first surface to form a stepped structure. The stepped structure has an opening on one side of the first surface and is used to support the substrate.

[0020] In some embodiments, the stepped structure includes a receiving surface and an abutting surface. The receiving surface and the first surface are spaced apart along the axial direction of the through hole. The abutting surface is connected between the inner periphery of the first surface and the outer periphery of the receiving surface. The receiving surface is used to receive the first or second surface of the substrate, and the abutting surface is used to abut against the outer periphery of the substrate.

[0021] In some embodiments, the dimension of the abutment surface along the axial direction of the through hole is consistent with the distance between the two sides of the substrate;

[0022] The first surface of the base has an opening to form an operating groove, which is located on the outside of the stepped structure and opens on the side facing the abutment surface and communicates with the through hole.

[0023] In some embodiments, the two opposite sides of the base along the axial direction of the through hole are respectively a first surface and a second surface, and the support base is detachably connected to the second surface of the base;

[0024] The clamp includes multiple pressure blocks, which are distributed circumferentially on the first surface of the base. Each pressure block is detachably connected to the base, and the multiple pressure blocks are used to press the substrate together to fix the substrate to the base.

[0025] In some embodiments, each of the pressure blocks is provided with a first fixing member, and the base is provided with a plurality of second fixing members. Each pressure block is magnetically connected to the base through at least one second fixing member.

[0026] Both the first fixing member and the second fixing member are magnets.

[0027] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0028] In this application, since the through holes on the base correspond to the areas on the first and second sides of the substrate used for arranging the first connector and the second connector, respectively, the areas on either the first or second side of the substrate used for arranging the first connector can be exposed through the through holes while the substrate is supported by the base. This facilitates the arrangement of the first connector on the first side or the second connector on the second side of the substrate. Furthermore, since the position of the support member on the support base corresponds to the position of the through holes on the base, that is, the support member is arranged correspondingly to both the areas on the first and second sides of the substrate used for arranging the first connector. This allows the support member to abut against the first connector on the first side or the second connector on the second side after the support base is connected to the base, thereby clamping the first or second connector between the support base and the substrate and preventing it from falling off.

[0029] In other words, the above design allows the substrate to be mounted on the base with its first and second sides arranged vertically. This not only allows for the support of one of the first connectors on the first side and the second connectors on the second side of the substrate from below, but also facilitates the arrangement of the corresponding first or second connectors on the other side of the first and second sides of the substrate. This allows for the simultaneous arrangement of the first connector on the first side and the second connector on the second side of the substrate. This facilitates the subsequent soldering of the substrate and the first and second connectors arranged on their opposite sides in a single reflow oven process, avoiding the various product reliability risks caused by the use of two high-temperature reflow ovens in the prior art. It also solves the problem of the additional production line time required by two high-temperature reflow ovens, thereby improving product reliability, production efficiency, and reducing the power consumption of the production line.

[0030] Furthermore, since the support base and the base are detachably connected, it is convenient to quickly install and remove the support components and the base, so as to facilitate the rapid assembly of the substrate with the first connector and the second connector before welding, and at the same time, to facilitate the rapid disassembly of the lamp board after welding.

[0039] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0040] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] This application provides a clamp for holding and fixing a lamp panel. Specifically, the clamp is used to hold and fix the lamp panel during pre-welding assembly and throughout the welding process.

[0043] The lamp board includes a substrate and a first connector and a second connector disposed on the substrate. The two opposite sides of the substrate are a first side and a second side, respectively. The first side is used to connect to the first connector, and the second side is used to connect to the second connector.

[0044] Specifically, there are multiple first connectors, which are connected at intervals on the first surface. There are also multiple second connectors, which are connected at intervals on the second surface.

[0045] Specifically, the substrate is fixed to the first connector and the second connector by soldering with solder paste. Before soldering, multiple solder paste dots are provided at intervals on the first and second surfaces of the substrate. Each first connector is bonded to at least one solder paste dot to achieve initial fixation with the substrate, and each second connector is bonded to at least one solder paste dot to achieve initial fixation with the substrate.

[0046] The area on the first side of the substrate used to arrange the first connector is the first mounting area, and the area on the second side of the substrate used to arrange the second connector is the second mounting area.

[0047] The following detailed description of specific embodiments of the fixture of this application is provided in conjunction with the accompanying drawings.

[0048] Figure 1 This is a schematic diagram illustrating the effect of the clamp holding and fixing the lamp board in this embodiment. Figure 2 for Figure 1 A schematic diagram along the AA direction.

[0049] refer to Figure 1 and Figure 2 The fixture includes a base 1 and a support assembly 2. The base 1 supports the substrate 110. The base 1 has a through hole 11, which is arranged correspondingly to the area on the first surface for arranging the first connector 120 and the area on the second surface for arranging the second connector 130. The support assembly 2 includes a support base 21 and a support member 22 disposed on the support base 21. The support base 21 is detachably connected to the base 1. The position of the support member 22 on the support base 21 corresponds to the position of the through hole 11 on the base 1. The support member 22 is used to abut against the first connector 120 located on the first surface or the second connector 130 located on the second surface, so that the first connector 120 or the second connector 130 is clamped between the support base 21 and the substrate 110.

[0050] In this application, since the through hole 11 on the base 1 is arranged in a corresponding manner with the area on the first side of the substrate 110 where the first connector 120 is arranged and the area on the second side of the substrate 110 where the second connector 130 is arranged, the area on the first side of the substrate 110 where the first connector 120 is arranged or the area on the second side of the substrate 110 where the first connector 120 is arranged can be exposed through the through hole 11 while the substrate 110 is supported by the base 1, this facilitates the arrangement of the first connector 120 on the first side of the substrate 110 or the arrangement of the second connector 130 on the second side of the substrate 110. Furthermore, since the arrangement position of the support member 22 on the support base 21 corresponds to the arrangement position of the through hole 11 on the base 1, that is, the support member 22 is arranged in a corresponding manner with the area on the first surface of the substrate 110 where the first connector 120 is arranged and the area on the second surface of the substrate 110 where the first connector 120 is arranged, after the support base 21 is connected to the base 1, the support member 22 can abut against the first connector 120 on the first surface or the second connector 130 on the second surface, so that the first connector 120 or the second connector 130 is clamped between the support base 21 and the substrate 110, preventing the component from falling off.

[0051] In other words, the above design allows the substrate 110 to be mounted on the base 1 with its first and second surfaces arranged vertically. This allows for the support member 22 to abut and support one of the first connector 120 on the first surface and the second connector 130 on the second surface of the substrate 110 from below. It also facilitates the arrangement of the corresponding first connector 120 or second connector 130 on the other side of the first and second surfaces of the substrate 110. This allows for the simultaneous arrangement of the first connector 120 on the first surface and the second connector 130 on the second surface of the substrate 110. This makes it easier to complete the subsequent soldering of the substrate 110 with the first connector 120 and the second connector 130 on its opposite sides in a single reflow oven process. This avoids the various product reliability risks caused by the use of two high-temperature reflow ovens in the prior art. It also solves the problem of the additional production line time required by two high-temperature reflow ovens, thereby improving product reliability, production efficiency, and reducing the power consumption of the production line.

[0052] Furthermore, since the support base 21 and the base 1 are detachably connected, it is convenient to quickly install and remove the support component 2 and the base 1, so as to facilitate the rapid assembly of the substrate 110 with the first connector 120 and the second connector 130 before welding, and at the same time facilitate the rapid disassembly of the lamp board after welding.

[0053] Figure 3 for Figure 2 The diagram shows an exploded structural diagram of the structure shown.

[0054] refer to Figures 1 to 3 The base 1 is used to support the substrate 110. The base 1 is provided with a through hole 11, which is arranged in a corresponding manner to the area on the first surface of the substrate 110 where the first connector 120 is arranged and the area on the second surface of the substrate 110 where the second connector 130 is arranged. Specifically, the cross-section of the through hole 11 is larger than the area of ​​the first mounting area and the second mounting area of ​​the substrate 110.

[0055] Figure 4 for Figure 3 Enlarged structural diagram at point B.

[0056] refer to Figure 2 , Figure 3 and Figure 4 For example, the two opposite sides of the base 1 along the axial direction of the through hole 11 are a first surface 14 and a second surface 15, respectively. The inner peripheral wall of the base 1 is recessed outward near the first surface 14 to form a stepped structure 12. The stepped structure 12 is open on one side of the first surface 14 and is used to support the substrate 110.

[0057] Specifically, the stepped structure 12 includes a receiving surface 121 and an abutting surface 122. The receiving surface 121 and the first surface 14 are spaced apart along the axial direction of the through hole 11. The abutting surface 122 is connected between the inner periphery of the first surface 14 and the outer periphery of the receiving surface 121. The receiving surface 121 is used to receive the first or second surface of the substrate 110, and the abutting surface 122 is used to abut against the outer periphery of the substrate 110. This method allows the substrate 110 to be circumferentially limited by the abutment surface 122 when it is placed on the receiving surface 121. Furthermore, it enables the first mounting area and the second mounting area of ​​the substrate 110 to be directly aligned with the through hole 11. Since the cross-section of the through hole 11 is larger than the area of ​​the first mounting area and the second mounting area of ​​the substrate 110, the first mounting area or the second mounting area can be completely exposed through the through hole 11, thus avoiding obstruction of the first mounting area or the second mounting area and avoiding interference with the assembly operations of the first connector 120 or the second connector 130, thereby enabling the smooth assembly of the first connector 120 or the second connector 130.

[0058] Specifically, in practical applications, the base 1 is placed with the axis of the through hole 11 extending vertically. The substrate 110 can be placed on the stepped structure 12 with the edge of its first surface abutting the receiving surface 121. In this case, the first mounting area on the first surface of the substrate 110 and the through hole 11 are vertically aligned, and the first connector 120, located on the first surface of the substrate 110, extends into the through hole 11, thus preventing interference between the base 1 and the first connector 120. Alternatively, the substrate 110 can also be placed on the stepped structure 12 with the edge of its second surface abutting the receiving surface 121. In this case, the second mounting area on the second surface of the substrate 110 and the through hole 11 are vertically aligned, and the second connector 130, located on the second surface of the substrate 110, extends into the through hole 11, thus preventing interference between the base 1 and the second connector 130.

[0059] In this embodiment, the abutment surface 122 extends along the axial direction of the through hole 11, so that the abutment surface 122 can completely fit and abut the outer periphery of the substrate 110, thereby enhancing the limiting effect on the substrate 110 and improving the alignment accuracy between the first mounting area or the second mounting area of ​​the substrate 110 and the through hole 11.

[0060] The dimension of the abutment surface 122 along the axial direction of the through hole 11 is consistent with the distance between the two sides of the substrate 110. This ensures that when the substrate 110 is placed on the stepped structure 12, the side of the substrate 110 facing away from the abutment surface 121 is flush with the first surface 14 of the base 1. This design facilitates increasing the contact area between the abutment surface 122 and the outer periphery of the substrate 110, thereby enhancing the limiting effect on the substrate 110 and improving the alignment accuracy between the first mounting area or the second mounting area of ​​the substrate 110 and the through hole 11.

[0061] In other embodiments, the dimension of the abutment surface 122 along the axial direction of the through hole 11 may also be greater than or less than the distance between the two sides of the substrate 110.

[0062] In this embodiment, the first surface 14 of the base 1 has an opening to form an operating groove 13. The operating groove 13 is located on the outside of the stepped structure 12, and the operating groove 13 opens on the side facing the abutment surface 122 and communicates with the through hole 11. In practical applications, the operating groove 13 is used for the operator's hand to reach in, which facilitates the handling of the light panel.

[0063] The support assembly 2 includes a support base 21 and a support member 22 disposed on the support base 21.

[0064] The support base 21 is detachably connected to the base 1. For example, the support base 21 is provided with a first connector 31, and the base 1 is provided with a second connector 32. The second connector 32 is located outside the through hole 11. The arrangement position of the first connector 31 on the support base 21 corresponds to the arrangement position of the second connector 32 on the base 1. The first connector 31 and the second connector 32 are magnetically connected.

[0065] Specifically, the support base 21 has a first base surface 212 and a second base surface on opposite sides. The first base surface 212 of the support base 21 has an opening forming a mounting groove. The first connector 31 is accommodated in the mounting groove and fixedly connected to the support base 21. The second surface 15 of the base 1 has an opening forming a connecting groove. The second connector 32 is accommodated in the connecting groove and fixedly connected to the base 1. The arrangement of the connecting groove on the base 1 corresponds to the arrangement of the mounting groove on the support base 21. Furthermore, the first connector 31 is flush with the first base surface 212 of the support base 21, and the second connector 32 is flush with the second surface 15 of the base 1. This facilitates the corresponding fit of the first connector 31 and the second connector 32 to achieve magnetic fixation.

[0066] The mounting groove is adapted to the shape and size of the first connector 31. This design allows the first connector 31 and the mounting groove to engage in a snap-fit ​​relationship. Fixing the first connector 31 to the support base 21 effectively improves the connection strength between the first connector 31 and the support base 21. Similarly, the connecting groove is adapted to the shape and size of the second connector 32. This design allows the second connector 32 and the connecting groove to engage in a snap-fit ​​relationship. Fixing the second connector 32 to the base 1 effectively improves the connection strength between the second connector 32 and the base 1.

[0067] The first connector 31 and the second connector 32 have the same shape and size, and the surface of the first connector 31 can completely fit the surface of the second connector 32.

[0068] In other embodiments, the first connector 31 may also protrude from the first base surface 212 of the support 21, and the second surface 15 of the base 1 may protrude from the second connector 32. Since the first connector 31 and the second connector 32 are similar in shape and size, and the connecting groove is adapted to the second connector 32, the first connector 31 can extend into the connecting groove and engage with it. At the same time, it can magnetically fix itself to the second connector 32. That is, the connecting groove can limit the position of the first connector 31 and the second connector 32, thereby improving the alignment accuracy of the first connector 31 and the second connector 32, avoiding misalignment of the first connector 31 and the second connector 32 under external force after magnetic fixation, and improving the connection stability of the first connector 31 and the second connector 32, thus improving the connection stability of the base 1 and the support 21.

[0069] Alternatively, the second connector 32 can protrude from the second surface 15 of the base 1, and the first base surface 212 of the support 21 can protrude from the first connector 31. Since the first connector 31 and the second connector 32 are similar in shape and size, and the mounting groove is compatible with the first connector 32, the second connector 32 can be inserted into the mounting groove and engaged with it. At the same time, it can be magnetically fixed by fitting with the first connector 31. In other words, the mounting groove can limit the position of the second connector 32.

[0070] Alternatively, the first connector 31 can protrude from the first base surface 212 of the support base 21, and the second connector 32 can protrude from the second surface 15 of the base 1. This way, after the first connector 31 and the second connector 32 are magnetically attached, there is a gap between the second surface 15 of the base 1 and the first base surface 212 of the support base 21. This allows for easy observation of the alignment of the first connector 31 and the second connector 32 through the gap, so as to adjust the position of the first connector 31 or the second connector 32 and make the surface of the first connector 31 and the surface of the second connector 32 fully contact each other, thereby improving the connection strength between the two.

[0071] In some embodiments, the first connector 31 and the second connector 32 can also be connected to the support 21 and the base 1 by a snap-fit ​​mechanism.

[0072] In this embodiment, a plurality of first connectors 31 are arranged circumferentially on the support base 21, and a plurality of second connectors 32 are arranged circumferentially on the first surface 14 of the base 1. The arrangement positions of the plurality of first connectors 31 on the support base 21 correspond one-to-one with the arrangement positions of the plurality of second connectors 32 on the base 1, so that each first connector 31 can be magnetically attached to a corresponding second connector 32. This can significantly improve the connection strength between the base 1 and the support base 21.

[0073] Specifically, both the first connector 31 and the second connector 32 are magnets. When two magnets of the same shape are attracted together, the magnetic field lines form a continuous closed loop between the two magnets. After the magnetic fields are superimposed, the total magnetic flux density is significantly increased (e.g., if the magnetic flux density of a single magnet is B, the superimposed magnetic flux density approaches 2B), thereby enhancing the magnetic attraction force, improving the connection strength of the first connector 31 and the second connector 32, and thus improving the connection stability of the base 1 and the support 21.

[0074] In this embodiment, the first base surface 212 of the support base 21 has an opening to form a groove 211, and the position of the groove 211 on the support base 21 corresponds to the position of the through hole 11 on the base 1. The groove 211 is located between a plurality of first connectors 31.

[0075] The diameter of the groove 211 is greater than or equal to the inner diameter of the through hole 11. That is, when the first connector 31 and the corresponding second connector 32 are fully engaged, the inner circumferential wall of the support 21 is positioned at the outer circumference of the inner circumferential wall of the base 1. This design provides adjustment margin during the connection between the support 21 and the base 1, ensuring that the projection of the through hole 11 along its axial direction completely falls within the groove 211, while allowing the relative position of the support 21 and the base 1 to be adjustable, thus facilitating the full engagement of the first connector 31 and the corresponding second connector 32.

[0076] The second end of the support base 21 has an opening forming a receiving groove.

[0077] In this embodiment, the position of the support member 22 on the support base 21 corresponds to the position of the through hole 11 on the base 1. The support member 22 is used to abut against the first connector 120 on the first surface or the second connector 130 on the second surface, so that the first connector 120 or the second connector 130 is clamped between the support base 21 and the substrate 110.

[0078] For example, after the first connector 120 is pressed against the substrate 110 by the support member 22, the above design also facilitates the arrangement of the second connector 130 on the second surface of the substrate 110, so as to simultaneously realize the arrangement of the first connector 120 on the first surface and the second connector 130 on the second surface of the substrate 110. This facilitates the subsequent one-time reflow soldering of the substrate 110 with the first connector 120 and the second connector 130 arranged on its opposite sides, so as to avoid various product reliability risks caused by the use of two high-temperature reflows in the prior art. At the same time, it can solve the problem that two high-temperature reflows require an extra production line time, thereby improving product reliability, production efficiency, etc., and reducing the power consumption of the production line.

[0079] The support member 22 passes through the support base 21 and is movably connected to the support base 21, allowing the support member 22 to move relative to the support base 21. Specifically, the support base 21 has a through hole that communicates with the groove 211 and the receiving groove. The support member 22 passes through the through hole in the support base 21 and is movably engaged with the support base 21.

[0081] refer to Figure 2 , Figure 3 and Figure 5Specifically, the support member 22 includes a support rod 221 and a support block 222 disposed at the end of the support rod 221. The support rod 221 passes through a through hole and is movably engaged with the support base 21. The outer diameter of the support rod 221 is adapted to the inner diameter of the through hole. The surface of the support block 222 facing away from the support rod 221 is used to abut against the first connector 120 or the second connector 130. The outer diameter of the support block 222 is larger than the inner diameter of the through hole.

[0082] The support member 22 also includes a limiting block 223 located at the end of the support rod 221 opposite to the support block 222. The limiting block 223 and the support block 222 are located at opposite ends of the support base 21. The outer diameter of the limiting block 223 is larger than the inner diameter of the through hole. The limiting block 223 and the support block 222 cooperate to limit the support member 22 on the support base 21.

[0083] Optionally, the support block 222 and / or the limiting block 223 are detachably connected to the support rod 221. This allows the support block 222 and / or the limiting block 223 to be removed from the support rod 221, so that the support rod 221 can be removed from the support base 21, and operations such as replacing the support member 22 can be performed. At the same time, it is convenient to insert the support rod 221 into the through hole, and then quickly install the support member 22 on the support base 21 through the quick connection between the support block 222 and / or the limiting block 223 and the support rod 221.

[0084] In this embodiment, there can be multiple support members 22. At least one support member 22 is provided for one first connector 120 or one second connector 130. That is, one, two, three or more support members 22 can be selected to support one first connector 120 or one second connector 130 as needed. The support base 21 can be provided with multiple through holes, and each through hole can be provided with one support member 22.

[0085] In other embodiments, the number of perforations may be greater than the number of support members 22. In practical applications, some of the perforations can be selected for mounting the support members 22 as needed. In this case, the perforations are selected according to the positions of each first connector 120 on the first mounting area of ​​the substrate 110 or each second connector 130 on the second mounting area, so as to ensure that the selected perforations correspond one-to-one with the first connector 120 or the second connector 130, so that each support member 22 can support one first connector 120 or one second connector 130.

[0086] In this embodiment, the support component 2 may further include an elastic element 23 capable of elastic extension and retraction. The elastic element 23 is disposed on the support component 22, such that the end of the support component 22 can elastically contact the first connector 120 or the second connector 130 to be abutted.

[0087] For example, the elastic element 23 is sleeved on the support element 22, and the two axial ends of the elastic element 23 are connected between the support element 22 and the support base 21. When the support element 22 slides relative to the support base 21, the elastic element 23 can extend and retract in its axial direction to elastically support the first connector 120 or the second connector 130. That is, this design can absorb the pressure on the support block 222 by the elastic deformation of the elastic element 23, which can effectively reduce the instantaneous impact on the support block 222 at the moment of contact with the first connector 120 or the second connector 130, and automatically adjust the support force on the first connector 120 or the second connector 130 according to the load change of the support block 222 in the subsequent process, so as to adapt to the load fluctuation under different conditions (e.g., during the soldering process, the solder paste melts and solidifies, etc.), avoid damaging the first connector 120 or the second connector 130, thereby improving the yield of the first connector 120 or the second connector 130, and improving the processing quality, reliability and service life of the product.

[0088] Specifically, the elastic element 23 is sleeved on the support rod 221, and the two axial ends of the elastic element 23 are connected between the support seat 21 and the support block 222, or the two axial ends of the elastic element 23 are connected between the support seat 21 and the limiting block 223.

[0089] In other embodiments, the elastic element 23 can also be configured in other ways, as long as it can elastically contact the first connector 120 or the second connector 130 to be abutted. For example, the support element 22 may only include the support block 222, and the axial ends of the elastic element 23 are directly fixed between the support block 222 and the support base 21.

[0090] In this embodiment, the elastic element 23 is a spring.

[0091] refer to Figures 1 to 3 In this embodiment, the fixture also includes a plurality of pressure blocks 4, which are distributed at intervals along the circumference of the base 1. Each pressure block 4 is detachably connected to the base 1. The plurality of pressure blocks 4 are used to press the substrate 110 together to fix the substrate 110 on the base 1.

[0092] Figure 6 for Figure 1 A cross-sectional view along the DD direction.

[0093] refer to Figure 6For example, each pressure block 4 is provided with a first fixing member 51, and the base 1 is provided with a plurality of second fixing members 52. The second fixing members 52 are located outside the through hole 11. Each pressure block 4 is magnetically connected, adhesively connected, or snap-fitted to the base 1 by at least one second fixing member 52. Specifically, the second fixing member 52 is located on the first surface 14 of the base 1. The first fixing member 51 and the second fixing member 52 are magnetically fixed.

[0094] The arrangement of the first fixing member 51 on the pressure block 4, the arrangement of the second fixing member 52 on the base 1, and the cooperation between the first fixing member 51 and the second fixing member 52 can be referred to the arrangement of the first connecting member 31 on the support 21, the arrangement of the second connecting member 32 on the base 1, and the cooperation between the first connecting member 31 and the second connecting member 32 mentioned above, and will not be repeated here.

[0095] The first fastener 51 and the second fastener 52 have the same shape and size, and the surface of the first fastener 51 can completely fit the surface of the second fastener 52.

[0096] In this embodiment, both the first fixing member 51 and the second fixing member 52 are magnets. When two magnets of the same shape are attracted together, the magnetic field lines form a continuous closed loop between the two magnets. After the magnetic fields are superimposed, the total magnetic flux density is significantly increased (e.g., if the magnetic flux density of a single magnet surface is B, the superimposed magnetic flux density approaches 2B), thereby enhancing the magnetic attraction force, improving the connection strength of the first fixing member 51 and the second fixing member 52, and further improving the connection stability between the base 1 and the pressure block 4, as well as the strength of the pressure block 4 in pressing the substrate 110, thus improving the stability of the substrate 110.

[0097] In this embodiment, the pressure block 4 is fixed to the first surface 14 of the base 1 by the magnetic attraction of the first fixing member 51 and the second fixing member 52. At the same time, the pressure block 4 presses against the edge of the first or second surface of the substrate 110 and is located outside the first or second mounting area of ​​the substrate 110. In this way, while fixing the substrate 110 to the base 1, interference with the arrangement of the first connector 120 or the second connector 130 can be avoided.

[0098] In this embodiment, since the dimension of the receiving surface along the axial direction of the through hole 11 is consistent with the distance between the first and second surfaces of the substrate 110, that is, the side of the substrate 110 placed on the stepped structure 12 that is away from the receiving surface 121 is flush with the first surface 14 of the base 1, at this time, the entire end face of the pressure block 4 used to press the end of the substrate 110 can be a plane, so that the end of the pressure block 4 can simultaneously adhere to the first surface 14 of the base 1 and the first or second surface of the substrate 110, thereby simultaneously realizing the magnetic attraction fixation between the pressure block 4 and the base 1 and realizing the pressing of the substrate 110.

[0099] In other embodiments, when the dimension of the receiving surface 121 along the axial direction of the through hole 11 is greater than or less than the distance between the first and second surfaces of the substrate 110, that is, when a gap is formed between the side of the substrate 110 placed on the stepped structure 12 that is away from the receiving surface 121 and the first surface 14 of the base 1 along the axial direction of the through hole 11, the end of the pressing block 4 used to press the substrate 110 can be stepped. Specifically, the end of the pressing block 4 used to press the substrate 110 includes a first pressing surface, a limiting surface and a second pressing surface connected in sequence, and the first pressing surface, the limiting surface and the second pressing surface are connected to form a Z-shape. When the pressure block 4 is fixed on the base 1, a gap is formed between the first pressing surface and the second pressing surface in the axial direction of the through hole 11. This design is used to adapt to the gap formed in the axial direction of the through hole 11 between the side of the substrate 110 placed on the stepped structure 12 away from the receiving surface 121 and the first surface 14 of the base 1, so that the first pressing surface can fit with the first surface 14 of the base 1, and the second pressing surface can fit with the first or second surface of the substrate 110, thereby simultaneously realizing the magnetic fixation between the pressure block 4 and the base 1 and realizing the pressing of the substrate 110.

[0100] When the dimension of the receiving surface 121 along the axial direction of the through hole 11 is greater than or less than the distance between the first and second surfaces of the substrate 110, that is, when the side of the substrate 110 placed on the stepped structure 12 that is away from the receiving surface 121 and the first surface 14 of the base 1 are separated in the axial direction of the through hole 11, the end of the pressing block 4 used to press the substrate 110 can be stepped. Specifically, the end of the pressure block 4 used to press the substrate 110 includes a first pressing surface and a second pressing surface. When the pressure block 4 is fixed on the base 1, a gap is formed between the first pressing surface and the second pressing surface in the axial direction of the through hole 11. This design is used to adapt to the gap formed in the axial direction of the through hole 11 between the side of the substrate 110 placed on the stepped structure 12 away from the receiving surface 121 and the first surface 14 of the base 1, so that the first pressing surface can fit with the first surface 14 of the base 1, and the second pressing surface can fit with the first or second surface of the substrate 110, thereby simultaneously realizing the magnetic fixation between the pressure block 4 and the base 1 and realizing the pressing of the substrate 110.

[0101] The following is an example of how the above-mentioned fixture can be used:

[0102] The base 1 is placed on the support surface with its first surface 14 facing upwards. At this time, the axis of the through hole 11 on the base 1 extends vertically, and the stepped structure 12 faces upwards. The support surface at this point can be any plane.

[0103] The substrate 110 is placed on the stepped structure 12 with its first and second surfaces arranged vertically. For example, the first surface of the substrate 110 is attached to the receiving surface 121 of the stepped structure 12, and the second surface faces upward. Both the first and second surfaces of the substrate 110 are provided with a plurality of solder paste dots at intervals.

[0104] Multiple pressure blocks 4 are connected and fixed to the first surface 14 of the base 1 respectively by the first fixing member 51 and the second fixing member 52, so that each pressure block 4 presses and fixes the substrate 110 on the base 1. Then the above structure is flipped so that the first surface 14 of the base 1 faces down, the first surface of the substrate 110 faces up, and the second surface faces down.

[0105] Multiple first connectors 120 are arranged on the first surface of the substrate 110. Each first connector 120 is bonded to the substrate 110 by at least one solder paste dot to achieve initial fixation of the first connector 120.

[0106] After the first connector 120 is arranged, the support base 21 of the support assembly 2 is connected and fixed to the base 1 through the first connector 31 and the second connector 32, and each support member 22 abuts against a corresponding first connector 120, thus pressing the first connector 120 against the substrate 110. Then, the entire structure is flipped so that the first surface 14 of the base 1 faces upward, the first surface of the substrate 110 faces downward and the second surface faces upward, and the support member 22 of the support assembly 2 abuts against the first connector 120 located on the first surface of the substrate 110 from below to prevent the first connector 120 from falling off.

[0107] Since the above structure is flipped over again so that the second side of the substrate 110 faces upward, it is convenient to arrange multiple second connectors 130 on the second side of the substrate 110. Each second connector 130 can be bonded to the substrate 110 by at least one solder paste dot to achieve the initial fixation of the second connector 130. This facilitates the subsequent one-time reflow to achieve the soldering and fixation between the first connector 120, the second connector 130 and the substrate 110.

[0108] It should be noted that in practical applications, the second connector 130 can be arranged on the second surface of the substrate 110 first using a fixture, and then the first connector 120 can be arranged on the first surface of the substrate 110. Furthermore, the order of steps described above does not represent the actual order of steps in operation; the specific steps depend on the needs and are not limited here.

[0109] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
