[0002] In related technologies, the solder joint fit of server PCBA boards (or other components, taking server PCBA boards as an example) needs to be tested after soldering. However, the current method for testing solder joint fit involves visually inspecting each component soldered to the PCBA board after soldering to check the solder joint fit. This method is not only inefficient, but its accuracy also depends entirely on the experience and condition of the inspector, resulting in extremely poor precision. Summary of the Invention

A fixing device configured to fix the first component to the support portion; A clamping device configured to apply pressure toward the first component to the second component; A first detection element is disposed on the clamping device and configured to obtain the distance between the second component and the first component connected thereto.

[0005] The fixture of this application, by setting a first detection element, can obtain the distance between the second component and the connected first component through the first detection element, so as to realize the automatic detection of fit. It is highly efficient and accurate. Furthermore, it can achieve a tight connection between detection and processing, which is conducive to improving production efficiency. In addition, by setting a clamping device, it is beneficial to improve the processing quality of the fixture and reduce the rework rate. Attached Figure Description

[0011] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] The following is for reference. Figures 1-11A jig 100 according to an embodiment of the present invention is described.

[0013] like Figures 1-3 , Figures 6-8 As shown, the fixture 100 according to an embodiment of the present invention includes: a workbench 10, a fixing device 20, a clamping device 30, and a first detection element 40.

[0014] The workbench 10 has a support portion 114 configured to support a first component 80, on which a second component 81 is placed. The workbench 10 is also configured to connect the second component 81 to the first component 80. Specifically, the first component 80 can be placed on the support portion 114 so that the support portion 114 supports the first component 80, and the second component 81 can be placed on the first component 80. The workbench 10 enables the second component 81 placed on the first component 80 to connect with the first component 80. As some embodiments of this application, the workbench 10 can be configured as a soldering heating station, the first component 80 can be configured as a circuit board, the second component 81 can be configured as an electronic component, and the support portion 114 is a heating module of the soldering heating station. Before heating by the soldering heating station, the electronic component can be placed (e.g., attached to) the circuit board, and then the soldering heating station is activated. The soldering heating station generates heat to solder the electronic component with solder paste. The workbench 10 can also be constructed as other types of heating tables, and the first component 80 and the second component 81 are not limited to the embodiments mentioned above.

[0015] The fixing device 20 is configured to fix the first component 80 to the support portion 114. In some embodiments of this application, the fixing device 20 can clamp the first component 80 between the fixing device 20 and the worktable 10 to achieve the effect of fixing the first component 80 to the support portion 114. Alternatively, the fixing device 20 can clamp the first component 80 between two sub-components to achieve the effect of fixing the first component 80 to the support portion 114. By providing the fixing device 20, the stability of the first component 80 during processing and inspection can be improved, the risk of the first component 80 shifting during processing and inspection can be reduced, and processing accuracy and inspection accuracy can be improved.

[0016] The clamping device 30 is configured to apply pressure toward the first component 80 to the second component 81. As some embodiments of this application, the clamping device 30 can be positioned along the height direction of the fixture 100 (i.e., Figure 1 , Figure 2 , Figure 6 , Figure 8Moving in the Z direction (as shown), the clamping device 30 can press down on the second component 81 to apply pressure toward the first component 80 to the second component 81. By applying pressure toward the first component 80 to the second component 81 by the clamping device 30, the tightness of contact between the second component 81 and the first component 80 can be improved, thereby improving the processing quality. As some embodiments of this application, by applying pressure toward the first component 80 to the second component 81 by the clamping device 30, the tightness of contact between the second component 81 (electronic component) and the solder paste can be improved, thereby improving the bonding strength between the second component 81 (electronic component) and the first component 80 (circuit board).

[0017] As some embodiments of this application, the fixture 100 may further include: a drive device 50, which may be disposed on the worktable 10, and the drive device 50 may be connected to the clamping device 30 for driving the clamping device 30 along the height direction of the fixture 100 (i.e., Figure 1 , Figure 2 , Figure 6 , Figure 8 Move in the Z direction (as shown).

[0018] The first detection element 40 is disposed on the clamping device 30 and configured to obtain the distance between the second component 81 and the connected first component 80. As some embodiments of this application, the first detection element 40 can be constructed as a camera, with the camera end facing the connection point between the second component 81 and the connected first component 80, to obtain the distance between the second component 81 and the connected first component 80. The first detection element 40 can be disposed on the clamping device 30 by means of, but not limited to, snap-fit, bolt connection, etc.

[0019] As some embodiments of this application, the fixture 100 may further include: a controller, which can be communicatively connected to the first detection element 40, and the controller can receive the spacing information between the second component 81 and the connected first component 80 obtained by the first detection element 40.

[0020] As some embodiments of this application, the fixture 100 may further include: an alarm device, which can be communicatively connected to a controller. The controller can receive the distance information between the second component 81 and the connected first component 80 obtained by the first detection element 40 and compare the distance information with a preset distance value. If the distance information is greater than the preset distance value, an alarm is triggered by the alarm device. As some embodiments of this application, the alarm device may include: an alarm light, which can be used to trigger an alarm by illuminating or flashing the alarm light. The alarm device may also include: a speaker, which can be used to trigger an alarm by emitting an alarm sound through the speaker.

[0021] It should be noted that by integrating the first detection component 40 into the fixture 100, the processing and detection can be integrated, and the fit can be detected in a timely manner after processing. Furthermore, the fit can be automatically detected, thereby improving production efficiency. Moreover, by setting the clamping device 30, pressure can be applied to the second component 81 toward the first component 80 to improve the tightness of contact between the second component 81 and the first component 80, thereby improving the fit.

[0022] Therefore, by setting the first detection element 40, the distance between the second component 81 and the connected first component 80 can be obtained through the first detection element 40, so as to realize the automatic detection of fit, which is efficient and accurate. In addition, it can realize the tight connection between detection and processing, which is conducive to improving production efficiency. Furthermore, by setting the clamping device 30, it is beneficial to improve the processing quality of the fixture 100 and reduce the rework rate.

[0023] In some embodiments of the present invention, such as Figures 1-5 As shown, the fixing device 20 includes a fixing mechanism 21, which includes multiple fixing parts 211 and a support frame 212. The support frame 212 is disposed on the workbench 10. As some embodiments of this application, the support frame 212 can be disposed on the workbench 10 by welding, bolting, snap-fitting, etc.

[0024] The fixing member 211 is rotatably disposed on the support frame 212 and configured to clamp and fix the first component 80 between the fixing member 211 and the support portion 114. The fixing member 211 can be sleeved on the support frame 212 so that it is rotatably disposed thereon. By rotating the fixing member 211, it can be moved closer to or further away from the first component 80. By rotating the fixing member 211 to a position that fits against the upper surface of the first component 80, the first component 80 can be clamped and fixed between the fixing member 211 and the support portion 114, thereby achieving the effect of fixing the first component 80, reducing the risk of the first component 80 shifting during processing and inspection, and improving processing and inspection accuracy.

[0025] As some embodiments of this application, such as Figure 3As shown, a first fastener 213 is installed on the support frame 212. The first fastener 213 is threadedly engaged with the support frame 212. Along the rotation axis of the fixing member 211, both ends of the fixing member 211 are provided with the first fastener 213. By turning the first fastener 213, the fixing member 211 can be locked and unlocked. When the fixing member 211 is locked by the first fasteners 213 at both ends, the fixing member 211 cannot rotate, thereby reliably achieving the effect of clamping and fixing the first component 80. When the fixing member 211 is separated from the first fasteners 213 at both ends by turning the first fasteners 213 at both ends, the fixing member 211 can rotate, thereby achieving the effect of unlocking the fixing member 211.

[0026] By using multiple fixing members 211, the first component 80 can be clamped simultaneously from different positions, resulting in uniform clamping force. This reduces the risk of the first component 80 shifting or tilting due to single-point clamping, and improves the flatness of the first component 80's positioning on the support 114. The fixing members 211 are rotatably mounted on the support frame 212 and can clamp and fix the first component 80. The clamping angle and clamping range can be adjusted by rotating the fixing members 211, making it adaptable to first components 80 of different shapes and sizes. Multiple workpieces can be positioned without replacing the entire device, demonstrating good versatility.

[0027] In some embodiments of the present invention, such as Figures 2-5 As shown, the support frame 212 is configured to move toward or away from the support portion 114. As some embodiments of this application, along the first direction (i.e....) Figure 2 (in the X direction shown) A support frame 212 is arranged on at least one side of the support portion 114. The support frame 212 is movably disposed on the worktable 10 and can move closer to or away from the support portion 114. As some embodiments of this application, along the second direction (i.e. Figure 2 (As shown in the Y direction), a support frame 212 is arranged on at least one side of the support part 114. The support frame 212 is movably disposed on the worktable 10 and can move closer to or away from the support part 114. Any two of the first direction, the second direction, and the height direction of the fixture 100 are perpendicular to each other.

[0028] As some embodiments of this application, the workbench 10 is provided with a slide rail, and the support frame 212 is movably disposed on the slide rail so as to achieve the effect that the support frame 212 can move closer to or further away from the support part 114.

[0029] As some embodiments of this application, such as Figure 2 , Figure 4 , Figure 5As shown, the workbench 10 is provided with a slide groove 1111, and the support frame 212 is movably engaged with the slide groove 1111 to achieve the effect of the support frame 212 being able to move closer to or further away from the support part 114. As some embodiments of this application, along the second direction (i.e. Figure 2 (as shown in the Y direction), at least one side of the bearing portion 114 is provided with a second direction (i.e. Figure 2 The groove 1111, extending in the Y direction (as shown), is one of the embodiments of this application, extending along the first direction (i.e., Figure 2 (as shown in the X direction), at least one side of the support portion 114 is provided with a first direction (i.e. Figure 2 The slide groove 1111 extends in the X direction (as shown). The number of slide grooves 1111 corresponds one-to-one with the number of fixing mechanisms 21. The support frame 212 of the fixing mechanism 21 cooperates with the corresponding slide groove 1111 and can slide along the extension direction of the corresponding slide groove 1111.

[0030] This configuration allows for adjustment of the position of the support frame 212, which in turn adjusts the position of the fixing mechanism 21, enabling the fixing mechanism 21 to match different specifications of the first component 80 and improving the adaptability of the fixing mechanism 21.

[0031] As some embodiments of this application, such as Figures 3-5 As shown, the support frame 212 includes: a mounting plate 2121, a mounting rod 2122, a second fastener 2123, and a fastening fitting 2124. Along the extension direction of the mounting rod 2122, both ends of the mounting rod 2122 are connected to the mounting plate 2121. A fixing member 211 is rotatably mounted on the mounting rod 2122. A first fastener 213 for locking or unlocking the fixing member 211 is sleeved on the mounting rod 2122. The mounting plate 2121 includes a connecting plate body 21211 and a fitting plate body 21212. The connecting plate body 21211 is connected to the mounting rod 2122, and the fitting plate body 21212 is connected to the connecting plate body 21211 and forms an angle with it. For example, the fitting plate body 21212 is perpendicular or approximately perpendicular to the connecting plate body 21211 to form an L-shaped structure. The mating plate 21212 and the connecting plate 21211 can be connected by means of, but not limited to, welding, snap-fitting, etc., or the mating plate 21212 and the connecting plate 21211 can be integrally formed. The mounting plate 2121 and the mounting rod 2122 can be connected by means of, but not limited to, welding, snap-fitting, etc., or the mounting plate 2121 and the mounting rod 2122 can be integrally formed.

[0032] The fastening fitting 2124 is partially located within the corresponding slide groove 1111 and passes through the mating plate 21212. The second fastener 2123 is located at the upper end of the mating plate 21212 and is threadedly engaged with the part of the fastening fitting 2124 located at the upper end of the mating plate 21212. By tightening the second fastener 2123, the mating plate 21212 can be pressed against the surface of the workbench 10 to lock the mating plate 21212. Furthermore, by tightening the second fastener 2123, the mating plate 21212 can be unlocked. This achieves the locking and unlocking effect of the support frame 212, facilitating the adjustment of the position of the support frame 212 and reliably achieving the effect of clamping and fixing the first component 80.

[0033] As some embodiments of this application, the first fastener 213 and the second fastener 2123 can both be constructed as nuts, the fastening fitting 2124 can be constructed as a bolt, and the screw head of the fastening fitting 2124 can be provided in the slide groove 1111.

[0034] In some embodiments of the present invention, such as Figure 3 As shown, the fixing member 211 has a fixed arc surface 2111, which is configured to clamp and fix the first component 80 between the fixing member 211 and the support portion 114. It is understood that when the fixing member 211 clamps and fixes the first component 80 between the fixing member 211 and the support portion 114, a portion of the surface of the fixing member 211 contacts the first component 80. This surface is at least a portion of the fixed arc surface 2111. In other words, when the fixing member 211 rotates to a position directly above the support portion 114, the surface of the fixing member 211 facing the support portion 114 forms the fixed arc surface 2111. The fixed arc surface 2111 can be constructed as a circular arc surface or an elliptical arc surface. When the fixing member 211 contacts the first component 80, specifically the fixed arc surface 2111 contacts the first component 80 to clamp and fix the first component 80 between the fixing member 211 and the support portion 114. This design reduces the risk of the fastener 211 scratching or damaging the first component 80. In addition, the curved surface has a larger clamping contact area with the first component 80, resulting in uniform clamping force and better fixing effect.

[0035] In some embodiments of the present invention, such as Figure 3 As shown, there are multiple fixing mechanisms 21, which are arranged around the support portion 114. For example, along the first direction (i.e. Figure 2 (as shown in the X direction), a fixing mechanism 21 is arranged on at least one side of the bearing portion 114, and, along the second direction (i.e. Figure 2(As shown in the Y direction), a fixing mechanism 21 is arranged on at least one side of the bearing portion 114, so that multiple fixing mechanisms 21 are arranged around the bearing portion 114. This arrangement can form a uniform clamping force from at least both sides of the first component 80. It is understood that fixing on one side is prone to problems such as one-sided lifting and tilting of the plate. Multi-directional synchronous clamping can improve the stability of the fixation, reduce the risk of displacement, and ensure the fixation reliability of the first component 80 throughout the soldering heating and pressing process as much as possible, thereby improving the processing quality and inspection accuracy of the fixture 100.

[0036] In some embodiments of the present invention, such as Figures 6-8 As shown, the jig 100 also includes: a driving device 50, and a clamping device 30 including: a pressure plate 31, a connecting rod 32, and an assembly plate 33, along the height direction of the jig 100 (i.e., Figure 1 , Figure 2 , Figure 6 , Figure 8 (As shown in the Z direction), the upper end of the connecting rod 32 is connected to the assembly plate 33 and the lower end is connected to the pressure plate 31. The connecting rod 32 can be connected to the assembly plate 33 and the pressure plate 31 by means of, but not limited to, snap-fit, bolt connection, etc.

[0037] Drive unit 50 is configured to drive clamping device 30 along the height direction of fixture 100 (i.e., Figure 1 , Figure 2 , Figure 6 , Figure 8 As shown in the Z direction, the workbench 10 includes, as some embodiments of this application, a table body 11, which has a support portion 114. Specifically, the table body 11 includes a table body 111, a fixed top plate 112, and a support rod 113. The table body 111 has a support portion 114, a fixing mechanism 21 is provided on the table body 111, the support rod 113 is provided on the table body 111, the top plate is provided on the support rod 113, and there can be multiple support rods 113.

[0038] like Figure 6 As shown, the driving device 50 includes: a driving component 51 and a lifting plate 52. The driving component 51 can be disposed on the platform 111, and the support rod 113 passes through the lifting plate 52. The lifting plate 52 is located between the platform 111 and the top plate and can extend along the extension direction of the support rod 113 (i.e., Figure 1 , Figure 2 , Figure 6 , Figure 8 The support rod 113 can act as a guide, and the drive member 51 is connected to the lifting plate 52 and configured to drive the lifting plate 52 along the height direction of the fixture 100 (i.e., the height direction). Figure 1 , Figure 2 , Figure 6 , Figure 8The clamping device 30 can be connected to the lifting plate 52 of the drive device 50 to enable the drive device 50 to drive the clamping device 30 along the height direction of the fixture 100 (i.e., the Z direction shown). Figure 1 , Figure 2 , Figure 6 , Figure 8 The effect of movement in the Z direction (as shown) is such that, for example, the mounting plate 33 of the clamping device 30 can be connected to the lifting plate 52 of the drive device 50.

[0039] The pressure plate 31 is configured to contact the second component 81. Specifically, the drive device 50 drives the clamping device 30 along the height direction of the fixture 100 (i.e., Figure 1 , Figure 2 , Figure 6 , Figure 8 The clamping device 30 is moved downwards (in the Z direction shown) so that the pressure plate 31 contacts the second component 81. This arrangement allows the clamping device 30 to be driven by the drive device 50 along the height direction of the fixture 100 (i.e., the Z direction shown). Figure 1 , Figure 2 , Figure 6 , Figure 8 The pressure plate 31 moves in the Z direction (as shown) to contact the second component 81, so that pressure is applied directly to the second component 81 towards the first component 80 through the pressure plate 31. The moving direction of the pressure device 30 is the same as the direction of force applied to the second component 81, which helps to improve the tightness of the contact between the second component 81 and the first component 80 and improve the processing quality.

[0040] In some embodiments of the present invention, such as Figures 8-10 As shown, the fixture 100 also includes a second detection element 41, which is rotatably disposed on the pressure plate 31. The second detection element 41 can cooperate with the pressure plate 31 through a rotating shaft to be rotatably disposed on the pressure plate 31.

[0041] The clamping device 30 also includes a linkage 34 and a reset mechanism 35. The linkage 34 is connected between the connecting rod 32 and the assembly plate 33. That is, the upper end of the connecting rod 32 is connected to the linkage 34 and the lower end is connected to the pressure plate 31. The linkage 34 is connected to the assembly plate 33. The connecting rod 32 and the linkage 34, and the linkage 34 and the assembly plate 33 can be connected by means of, but not limited to, bolt connection, snap-fit, etc.

[0042] The linkage 34 is configured to move relative to the assembly plate 33 along a first direction perpendicular to the rotation axis of the second detection element 41 during the upward movement of the clamping device 30, so that the second detection element 41 applies a pushing force to the second component 81. The reset mechanism 35 is configured to drive the linkage 34 to reset when the clamping device 30 moves upward to a preset position. Specifically, during the processing, the drive device 50 drives the clamping device 30 along the height direction of the fixture 100 (i.e., Figure 1 , Figure 2 , Figure 6 , Figure 8 The pressure plate 31 moves downward in the Z direction (as shown) to apply pressure to the second component 81 toward the first component 80. Then, the worktable 10 can heat up to connect the second component 81 to the first component 80. Then, the first detection element 40 obtains the distance between the second component 81 and the connected first component 80. Then, the drive device 50 drives the clamping device 30 along the height direction of the fixture 100 (i.e., in the Z direction). Figure 1 , Figure 2 , Figure 6 , Figure 8 The clamping device 30 moves upward in the Z direction (as shown), along the height direction of the fixture 100 (i.e., Figure 1 , Figure 2 , Figure 6 , Figure 8 During the upward movement (in the Z direction shown), the linkage 34 can move relative to the assembly plate 33 in a first direction perpendicular to the rotation axis of the second detection element 41. During this movement, the linkage 34 can drive the connecting rod 32 and the pressure plate 31 to move together, thereby driving the first detection element 40 and the second detection element 41, which are located on the pressure plate 31, to move together. During this movement, the second detection element 41 can contact the second component 81 to apply a pushing force to it. The first detection element 40 is configured to acquire the displacement of the second component 81. The clamping device 30 moves along the height direction of the fixture 100 (i.e.,...) Figure 1 , Figure 2 , Figure 6 , Figure 8 When the Z-direction shown moves upward to the preset position, the reset mechanism 35 drives the linkage 34 to reset. Specifically, the reset mechanism 35 drives the linkage 34 to move along the first direction to reset the linkage 34.

[0043] As some embodiments of this application, the linkage 34 can cooperate with slide rails, slide rails, etc., to enable the linkage 34 to move relative to the assembly plate 33 in the first direction during the upward movement of the clamping device 30.

[0044] Understandably, the first detection element 40 is used to obtain the displacement of the second component 81. If the second detection element 41 can push the second component 81 to move relative to the first component 80, and the displacement of the second component 81 exceeds a preset displacement value, it indicates that the connection between the second component 81 and the first component 80 is not firm (e.g., poor welding). If the second detection element 41 cannot push the second component 81 to move relative to the first component 80, or the displacement of the second component 81 does not exceed the preset displacement value, it indicates that the connection between the second component 81 and the first component 80 is firm (e.g., good welding). Furthermore, since the linkage 34 moves relative to the assembly plate 33 in a first direction perpendicular to the rotation axis of the second detection element 41 during the upward movement of the clamping device 30, if the connection between the second component 81 and the first component 80 is firm (e.g., good welding), the second detection element 41 will rotate in a direction away from the second component 81 to reduce the risk of the second component 81 and the first component 80 becoming loose due to excessive thrust applied by the second detection element 41 towards the second component 81.

[0045] As some embodiments of this application, the fixture 100 may further include: a controller, which can be communicatively connected to the first detection element 40, and can receive the displacement of the second component 81 obtained by the first detection element 40. As some embodiments of this application, the fixture 100 may further include: an alarm device, which can be communicatively connected to the controller, and can receive the displacement of the second component 81 obtained by the first detection element 40 and compare the displacement information with a preset displacement value. If the displacement is greater than the preset displacement value, an alarm is triggered by the alarm device. As some embodiments of this application, the alarm device may include: an alarm light, which can be used to trigger an alarm by illuminating or flashing the alarm light; the alarm device may also include: a speaker, which can be used to trigger an alarm by emitting an alarm sound.

[0046] This configuration integrates the second detection element 41 into the fixture 100, enabling integrated processing and inspection. It allows for timely testing of fit and weld strength after processing, and both types of information can be obtained through the first detection element 40. The design is ingenious. Furthermore, the application of the thrust of the second detection element 41 is synchronized with the upward movement of the clamping device 30, resulting in a tight process connection and significantly improved production efficiency. In addition, by making the first direction perpendicular to the rotation axis of the second detection element 41, if the connection between the second component 81 and the first component 80 is firm (e.g., good welding), the second detection element 41 will rotate away from the second component 81. This reduces the risk of the second component 81 loosening due to excessive thrust applied by the second detection element 41 towards the second component 81, thus ensuring high reliability.

[0047] In some embodiments of the present invention, such as Figure 8 , Figure 9As shown, the clamping device 30 further includes: a first elastic element 36; a pressure plate 31 having an assembly groove 311; a portion of the structure of the second detection element 41 is disposed within the assembly groove 311 and rotatably connected to the pressure plate 31; the first elastic element 36 cooperates with the second detection element 41; the first elastic element 36 can be constructed as a torsion spring; the first elastic element 36 can be sleeved on a rotating shaft corresponding to the second detection element 41; the first elastic element 36 is configured to drive the second detection element 41 to rotate toward the inner wall of the second component 81 near the assembly groove 311; that is, the first elastic element 36 is used to drive the second detection element 41 to rotate toward the second component 81. As some embodiments of this application, the second detection element 41 is in contact with the inner wall of the assembly groove 311 near the second component 81, so that under the action of the inner wall of the second component 81, the second detection element 41 avoids applying a pushing force to the second component 81 during normal processing, ensuring the smooth progress of the processing. The assembly groove 311 provides space for the second detection element 41 to swing away from the second component 81.

[0048] Furthermore, by adjusting the torque of the first elastic element 36, the torque can be made reasonable, reducing the risk of damage to well-connected components due to excessive torque, and reducing the risk of connection defects not being detected due to insufficient torque, which helps to improve the rationality and accuracy of weld strength testing.

[0049] As some embodiments of this application, the number of clamping devices 30 can be one or more. Multiple clamping devices 30 can simultaneously process and inspect multiple components. A first detection element 40 can be provided on one pressure plate 31, or multiple first detection elements 40 can be provided on one pressure plate 31. A second detection element 41 can be provided on one pressure plate 31, or multiple second detection elements 41 can be provided on one pressure plate 31. The linkage 34 and the assembly plate 33 can be detachably connected, and the assembly plate 33 of the clamping device 30 can be detachably connected to the lifting plate 52 of the drive device 50 to improve the applicability of the fixture 100.

[0050] In some embodiments of the present invention, such as Figure 7 , Figure 8 , Figure 11 As shown, the worktable 10 includes: a table body 11, a trigger member 13, and a second elastic member 14. The table body 11 has a bearing portion 114. The trigger member 13 is rotatably disposed on the table body 11 and corresponds to the linkage member 34. The second elastic member 14 cooperates with the trigger member 13 and is configured to drive the trigger member 13 to rotate so that one end of the trigger member 13 contacts the table body 11.

[0051] As some embodiments of this application, the platform body 11 includes: a platform body 111, a fixed top plate 112, a support rod 113, and a limiting member 12. The platform body 111 has a bearing portion 114, a fixing mechanism 21 is disposed on the platform body 111, the support rod 113 is disposed on the platform body 111, the top plate is disposed on the support rod 113, and there can be multiple support rods 113. The limiting member 12 is disposed on the fixed top plate 112. As some embodiments of this application, the platform body 11 also includes: a fixing plate 15, the fixing plate 15 is disposed on the fixed top plate 112, and the limiting member 12 is disposed on the fixing plate 15.

[0052] The trigger 13 is rotatably disposed on the limiting member 12 and corresponds to the linkage member 34. The trigger 13 can be rotatably disposed on the limiting member 12 via a rotating shaft.

[0053] The second elastic element 14 cooperates with the trigger element 13 and is configured to drive the trigger element 13 to rotate so that one end of the trigger element 13 contacts the stage body 11. The second elastic element 14 can be constructed as a torsion spring. The second elastic element 14 can be sleeved on the rotating shaft corresponding to the trigger element 13. The second elastic element 14 can continuously apply torque to the trigger element 13 so that the trigger element 13 has a tendency to rotate so that one end of the trigger element 13 contacts the stage body 11 (specifically the limiting element 12).

[0054] The trigger 13 is configured to be pushed and rotated by the linkage 34 during the downward movement of the linkage 34 to avoid the linkage 34, and is also configured to guide the linkage 34 to move along the first direction during the upward movement of the linkage 34. Specifically, the drive device 50 drives the clamping device 30 along the height direction of the fixture 100 (i.e., Figure 1 , Figure 2 , Figure 6 , Figure 8 Moving downwards in the Z direction (as shown), the linkage 34 pushes the trigger 13 during its downward movement, causing the trigger 13 to rotate and avoid the linkage 34. It should be explained that the linkage 34 also pushes the other end of the trigger 13 during its downward movement, gradually increasing the distance between one end of the trigger 13 and the platform body 11 (specifically, the limiting member 12), allowing the trigger 13 to rotate and avoid the linkage 34. When the linkage 34 reaches a state where it separates from the trigger 13, under the action of the second elastic member 14, the trigger 13 rotates in the opposite direction until one end of the trigger 13 contacts the platform body 11 (specifically, the limiting member 12). It can be understood that because one end of the trigger 13 is in contact with and limited by the platform body 11 (specifically, the limiting member 12), the trigger 13 cannot continue to rotate. Afterwards, the drive device 50 drives the clamping device 30 along the height direction of the fixture 100 (i.e.,...). Figure 1 , Figure 2 , Figure 6 , Figure 8The linkage 34 moves upward in the Z direction shown. During the upward movement, the linkage 34 can contact the trigger 13. The trigger 13 can guide the linkage 34 to move in the first direction, so that the second detection element 41 moves in the first direction and applies a thrust to the second component 81.

[0055] As some embodiments of this application, the number of linkage members 34 and the number of limiting members 12 are the same and they correspond one-to-one.

[0056] In this way, mechanical linkage can be achieved through ingenious mechanical structure design, so that the linkage 34 can move along the first direction without an additional power source during the upward movement, thereby driving the second detection element 41 to move along the first direction and applying thrust to the second component 81. The energy-saving effect is obvious and the failure rate is low.

[0057] Understandably, under the action of the second elastic member 14, one end of the trigger member 13 contacts and limits the contact with the platform body 11 (specifically the limiting member 12). At this time, during the process of the linkage member 34 moving upward and contacting the trigger member 13, it cannot push the trigger member 13 to rotate. Therefore, under the action of the trigger member 13, the linkage member 34 moves along the first direction to gradually misalign with the trigger member 13. During this process, it can drive the second detection member 41 to move along the first direction and apply a pushing force to the second component 81. When the linkage member 34 moves along the first direction to a position misaligned with the trigger member 13, the trigger member 13 cannot stop the upward movement of the linkage member 34. The linkage member 34 will move upward under the driving action of the driving device 50. When the pressing device 30 moves upward to the preset position, the reset mechanism 35 drives the linkage member 34 to reset.

[0058] As some embodiments of this application, a sliding groove 1111 is provided on the platform 111.

[0059] In some embodiments of the present invention, such as Figure 8 , Figure 11 As shown, the other end of the trigger 13 has a guide surface 131, which is configured to contact the linkage 34 during the upward movement of the linkage 34 and guide the linkage 34 to move along the first direction.

[0060] It is understood that the trigger 13 has two opposite ends, and the second elastic member 14 cooperates with the trigger 13 and is configured to drive the trigger 13 to rotate so that one end of the trigger 13 contacts the stage body 11. The other opposite end of the trigger 13 forms a guide surface 131, which can be constructed as a guide slope or a guide arc surface. During the upward movement of the linkage 34, it can contact the guide surface 131 of the trigger 13. The guide surface 131 can guide the linkage 34 to move along the first direction. It is understood that under the action of the second elastic member 14, one end of the trigger 13 contacts and limits the stage body 11 (specifically the limiting member 12). At this time, during the upward movement of the linkage 34 and its contact with the guide surface 131 of the trigger 13, it cannot push the trigger 13 to rotate. Therefore, under the action of the guide surface 131, the linkage 34 moves along the first direction to gradually misalign with the trigger 13. During this process, it can drive the second detection member 41 to move along the first direction and apply a thrust to the second component 81. By forming a guide surface 131 at the other end of the trigger 13, the risk of jamming with the trigger 13 during the upward movement of the trigger 13 can be reduced, thereby improving the working reliability of the fixture 100.

[0061] In some embodiments of the present invention, the connecting rod 32 is constructed as a telescopic rod. As some embodiments of this application, the connecting rod 32 includes: a first rod body, a second rod body, and an elastic element. The first rod body forms a cavity, and the elastic element is disposed within the cavity. A portion of the second rod body is located within the cavity, and the elastic element is located between the bottom wall of the cavity and the second rod body. One of the first and second rod bodies is connected to the pressure plate 31, and the other is connected to the assembly plate 33 (or the linkage 34). The elastic element can be constructed as rubber, a spring, etc. This arrangement can reduce the risk of the pressure plate 31 damaging the second component 81 and / or the first component 80, and improve the operational reliability of the clamping device 30.

[0062] In some embodiments of the present invention, such as Figure 10 As shown, the reset mechanism 35 includes a third elastic member 351, which can be constructed as a spring, rubber, etc. One of the linkage member 34 and the assembly plate 33 defines a mounting groove 331, and the other forms a reset mating portion 341 with at least a partial structure located within the mounting groove 331. For example, the linkage member 34 defines the mounting groove 331, and the assembly plate 33 forms a reset mating portion 341 with at least a partial structure located within the mounting groove 331; or, the assembly plate 33 defines the mounting groove 331, and the linkage member 34 forms a reset mating portion 341 with at least a partial structure located within the mounting groove 331. This description uses the example of the assembly plate 33 defining the mounting groove 331 and the linkage member 34 forming a reset mating portion 341 with at least a partial structure located within the mounting groove 331.

[0063] The third elastic element 351 is installed between the reset mating part 341 and the first inner wall 3311 of the mounting groove 331, and is configured to be compressed during the upward movement of the linkage 34 and its movement in the first direction. It is also configured to drive the linkage 34 to reset when the clamping device 30 moves upward to a preset position. Specifically, during the upward movement of the linkage 34, it contacts the trigger 13. Under the action of the trigger 13, the linkage 34 moves in the first direction to gradually misalign with the trigger 13. During this process, it can drive the second detection element 41 to move in the first direction and apply a pushing force to the second component 81. During this process, the third elastic element 351 is gradually compressed between the reset mating part 341 and the first inner wall 3311 of the mounting groove 331. When the clamping device 30 moves upward to the preset position, the third elastic element 351 extends and drives the linkage 34 to reset. It can be understood that the reset of the linkage 34 means the reset of the entire clamping device 30.

[0064] This configuration enables the automatic reset of the linkage 34, which in turn enables the automatic reset of the clamping device 30. The ingenious structural design makes the fixture 100 easy to use, and it requires no additional power source, resulting in significant energy savings and reducing the cost of the fixture 100.

[0065] As some embodiments of this application, the second detection element 41 is constructed as a push plate.

[0066] In some embodiments of the present invention, such as Figure 10 As shown, the reset mechanism 35 further includes: a first magnetic element 352 and a second magnetic element 353. The first magnetic element 352 is installed on the end of the reset mating part 341 away from the third elastic element 351. The first magnetic element 352 can be installed on the end of the reset mating part 341 away from the third elastic element 351 by means of, but not limited to, bonding or snapping. The second magnetic element 353 is installed on the second inner wall 3312 of the mounting groove 331 opposite to the first inner wall 3311. The second magnetic element 353 can be installed on the second inner wall 3312 by means of, but not limited to, bonding or snapping. The first magnetic element 352 and the second magnetic element 353 have different magnetic properties.

[0067] As some embodiments of this application, one of the first magnetic element 352 and the second magnetic element 353 is a magnetic sheet, and the other of the first magnetic element 352 and the second magnetic element 353 is an iron sheet. With this configuration, when the pressing device 30 moves upward to the preset position, the first magnetic element 352 and the second magnetic element 353 attract each other to drive the linkage 34 to reset. This can improve the reliability of the linkage 34's reset, reduce the risk of the linkage 34 failing to reset due to the failure or damage of the third elastic element 351, and improve the working reliability of the reset mechanism 35.

[0068] As some embodiments of this application, the fixture 100 may further include an alarm device, which may include multiple alarm lights, with one second component 81 corresponding to one alarm light. The type of fault can be determined by the different colors of the alarm lights. For example, a purple light will illuminate when the fit is poor, a blue light will illuminate when there is a cold solder joint, a red light will illuminate when there are problems with both, and no light will illuminate when both are qualified.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application.
