Description

Technical Field

[0001] This invention relates to the field of SMT technology, and more particularly to the field of SMT inspection technology, specifically a horizontal push-pull force gauge. Background Technology

[0002] Push-pull force gauges are mechanical measuring instruments used in SMT solder joint strength and reliability assessment as metrology / testing equipment to quantitatively measure "push / pull force" and test the solder joint strength by simulating the stress conditions in actual use.

[0003] For example, the patent with authorization announcement number CN 210638846 U discloses a horizontal push-pull force gauge testing machine. To overcome the current problem of relying on force standard machines for testing push-pull force gauges, the horizontal push-pull force gauge testing machine includes a screw motion system, a frame, a centering connection device, a push-pull force gauge clamping system, and a linear motor motion system. The linear motor motion system is mounted on the left end of the frame base through a linear motor support plate. The push-pull force gauge clamping system is mounted on the linear motor motion system through the push-pull force gauge base. One end of the centering connection device is connected to the push-pull force gauge base, and the other end is connected to the screw nut base in the screw motion system, which simplifies motion transmission, makes the response faster, and the results more accurate.

[0004] For example, patent CN 213068486 U discloses a servo horizontal tensile testing machine, including a housing. A shell is fixedly connected to the right side of the top of the housing, and a vertical plate is fixedly connected to the top of the housing. A screw is movably connected to the side of the vertical plate opposite to the shell via a bearing. The right end of the screw extends into the inner cavity of the shell and is fixedly connected to a first sprocket. A threaded sleeve is threaded onto the surface of the screw. A slide rod is fixedly connected to the side of the vertical plate opposite to the shell. This design achieves left-right adjustment and allows for horizontal adjustment according to usage needs, effectively avoiding inconvenience for the user, improving the user experience of the servo horizontal tensile testing machine, meeting the demands of today's market, and enhancing the practicality and usability of the servo horizontal tensile testing machine.

[0005] However, considering the current push-pull force gauge testing equipment, there are still some shortcomings in its use during measurement operations, such as:

[0006] 1. Most of the machines use a clamping-type limiting and fixing method. When fixing the circuit board, not only is the fixing reliability poor, but it will also squeeze the circuit board and easily cause slippage. It cannot simulate the actual installation method of the circuit board, which is not conducive to improving the accuracy of measurement and testing.

[0007] 2. The machine's travel cannot be fully utilized. Due to the length of the connector between the measuring rod and the measuring point, the original machine travel design cannot guarantee that it can be used for measuring the maximum stress strength when testing the solder joint strength of the circuit board.

[0008] 3. Low compatibility: The machine cannot be properly fitted and fixed when installing circuit boards and push-pull force gauges of different specifications and models, and the stability of measurement and testing cannot be guaranteed.

[0009] Therefore, we propose a horizontal push-pull force gauge to solve the problems mentioned above. Summary of the Invention

[0019] A buckle is slidably installed inside the first clamping plate, and the top of the buckle engages with a corresponding slot.

[0021] Furthermore: the surface of the test piece base plate is provided with anti-slip pads, the side of the test piece base plate is symmetrically provided with first sliding grooves, the first slider is slidably connected inside the first sliding groove, and the side of the first sliding groove is provided with anti-detachment blocks that protrude inward to prevent the first sliding groove from slipping off.

[0022] Furthermore: the clamping mechanism includes:

[0023] A pressure plate is slidably connected to the outside of the vertical rod, and an anti-slip pad is fixedly connected to the bottom of the inner side of the pressure plate;

[0037] 1. This solution includes a support base plate, a machine frame, a connecting frame, and leveling bolts. The machine frame and the connecting frame are installed together on the surface of the support base plate. Leveling can be performed directly by installing leveling bolts on the bottom side of the support base plate, thereby improving the accuracy of measurement and testing.

[0038] 2. This solution includes a force gauge base plate, a sliding rod, a first clamping plate, and a second clamping plate. Through the sliding structure of the first clamping plate and the second clamping plate on both sides of the force gauge base plate, the force gauge placed on the surface of the force gauge base plate can be limited and clamped by the individual movement of the first clamping plate and the second clamping plate.

[0039] Furthermore, this solution includes a slot and a buckle.

[0040] 3. This solution includes a test piece base plate, a first slider, a clamping plate, and a locking block. The sliding of the first slider inside the first groove allows for adjustment of the front and rear positions of the clamping plate. The rotation and downward pressing of the locking block facilitates stable clamping of the circuit board by the clamping plate and allows for easy sliding adjustment according to the specifications of the circuit board.

[0041] 4. This solution includes a support rod, an adjusting rod, a worm gear, and a worm. Through the transmission between the worm gear and the worm, the support rod can be raised and lowered by the adjusting rod. Its self-locking mechanism ensures the height stability of the test piece's base plate, facilitating adaptability and improving testing efficiency.

[0042] 5. This solution includes a second slide, a second slider, and a telescopic rod. By extending and retracting the telescopic rod, the connecting frame can be pushed and pulled above the support base plate to adjust the distance between the machine frame and the connecting frame. The stroke can be guaranteed and additionally increased based on the length of the measuring connecting rod, and the overall volume of the device can be reduced, making its structure more compact and refined.

[0054] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0055] Please see Figures 1-9 The present invention provides the following technical solution:

[0056] A horizontal push-pull force gauge includes: a support base plate 1, a machine frame 2, a connecting frame 3, a control panel 4, a leveling bolt 5, a motor box 6, a lead screw 7, a limit rod 8, a force gauge base plate 9, a sliding rod 10, a protruding strip 11, a first clamping plate 12, a second clamping plate 13, a pressure plate 14, a slot 15, a buckle 16, a pull plate 17, a first spring 18, a test piece base plate 19, an anti-slip pad 20, a first sliding groove 21, a first slider 22, a vertical rod 23, a pressing plate 24, an anti-slip pressure pad 25, a second spring 26, a locking block 27, an anti-detachment block 28, a lower limit plate 29, an upper limit plate 30, a support rod 31, an adjusting rod 32, a worm gear 33, a worm 34, a handwheel 35, a transparent baffle 36, a second sliding groove 37, a second slider 38, a telescopic rod 39, a guide rail 40, and a push-pull rod 41.

[0057] Among them: such as Figure 1 , Figure 2 , Figure 3 and Figure 8In this system, the support base plate 1 is placed directly on the tabletop for use. The top right side of the support base plate 1 is fixed with a machine frame 2, and the top left side of the support base plate 1 is provided with a connecting frame 3. The front end of the machine frame 2 is equipped with a control panel 4. The bottom of the machine frame 2 is bolted to the support base plate 1. The bottom of the support base plate 1 is symmetrically equipped with leveling bolts 5. The top of the machine frame 2 is equipped with a lead screw 7. The top side of the machine frame 2 is fixed with a motor box 6. The output end of the motor box 6 is connected to the lead screw 7. The outer side of the lead screw 7 is symmetrically equipped with limit rods 8 fixed to the outer side of the motor box 6. The lead screw 7 and the limit rods 8 are installed parallel to each other on the top surface of the machine frame 2. The outer side of the lead screw 7 is threadedly connected to a force gauge base plate 9. The front side of the connecting frame 3 is slidably equipped with a transparent baffle 36, and the bottom of the transparent baffle 36 is provided with limit bolts.

[0058] The top surface of the force gauge base plate 9 is symmetrically fixed with a sliding rod 10. The two ends of the sliding rod 10 are slidably connected to a first clamping plate 12 and a second clamping plate 13, respectively. The first clamping plate 12 and the second clamping plate 13 are provided with a buckling mechanism for limiting and fixing with the sliding rod 10. The top of the connecting frame 3 is provided with a test piece base plate 19. The bottom surface of the test piece base plate 19 is connected to the connecting frame 3 through a height adjustment mechanism. A first slider 22 is slidably installed on the side of the test piece base plate 19. A vertical rod 23 is connected above the first slider 22. A clamping mechanism is installed on the outside of the vertical rod 23.

[0059] In specific application scenarios, the support base plate 1 is placed directly on the test table. The leveling bolts 5 on the bottom edge of the support base plate 1 are rotated to adjust its level, thereby maintaining the level of the machine frame 2 and the connecting frame 3. Before testing, the circuit board is placed on the surface of the test piece base plate 19. The sliding adjustment of the first slider 22 causes the clamping mechanism on the outside of the vertical rod 23 to clamp the edge of the circuit board, simulating the actual installation scenario. The force gauge is placed on the surface of the force gauge base plate 9, with the front probe of the force gauge aligned with the circuit board in the direction of force measurement. The force is then measured through the clamping mechanism on the surface of the force gauge base plate 9. The first clamping plate 12 and the second clamping plate 13 slide to clamp the force gauge. A connector connected to the force measuring point of the circuit board is installed at the end of the force gauge rod. Then, the height of the circuit board is adjusted by the height adjustment mechanism set on the bottom surface of the test piece base plate 19 so that the end of the connector is aligned with the force measuring point for measurement. The motor box 6 starts the lead screw 7 to rotate. The threaded transmission between the lead screw 7 and the force gauge base plate 9 slides the force gauge base plate 9, thereby pushing and pulling the force gauge for measurement and testing of the pushing and pulling force. At the same time, during measurement and testing, the transparent baffle 36 slides upward to protect the testing position and improve the safety of the test.

[0060] The above technical solution facilitates quick and adaptable fixing of the force gauge and circuit board, adapts to different specifications and models of force gauges and circuit boards, enables rapid connection of force measurement positions, improves metrological testing efficiency, and ensures metrological testing accuracy.

[0061] Among them: such as Figure 1 , Figure 4 and Figure 5 In the slide rod 10, a protruding strip 11 is integrally provided on the top inner side. The first clamping plate 12 and the second clamping plate 13 are symmetrically slidably connected to the outer side of the slide rod 10. The inner side of the first clamping plate 12 and the second clamping plate 13 is integrally provided with a pressure plate 14. The surface of the pressure plate 14 is provided with an anti-slip groove. The buckling mechanism is provided on the inner side of the first clamping plate 12 and the second clamping plate 13, which includes: a slot 15, a buckle 16, a pull plate 17 and a first spring 18. The slot 15 is symmetrically opened on the outer side of the slide rod 10. The vertical projection structure of the slot 15 is a right trapezoidal structure. The hypotenuse of the slot 15 is set towards the middle of the slide rod 10. The buckle 16 is slidably installed inside the first clamping plate 12. The top of the buckle 16 is correspondingly engaged with the slot 15. The pull plate 17 is fixedly connected to the outer side of the buckle 16. The outer side of the pull plate 17 is fitted with a first spring 18 that connects the buckle 16 and the first clamping plate 12.

[0062] In specific application scenarios, the slide rods 10 are symmetrically fixed to the surface of the force gauge base plate 9. A protruding strip 11 is provided on the inner top of the slide rod 10, which prevents the first clamping plate 12 and the second clamping plate 13 from disengaging while they slide and engage. During use, the first clamping plate 12 is first slidably adjusted to the left end of the force gauge base plate 9, so that its inner pressure plate 14 is in contact with the end of the force gauge with the measuring rod. Then, the second clamping plate 13 is pushed along the slide rod 10 from the right end of the force gauge base plate 9, causing the second clamping plate 13 to be in contact with the other end of the force gauge via its inner pressure plate 14. This allows the second clamping plate 13 and the first clamping plate 12 to jointly clamp and fix the force gauge. The first clamping plate 12 and the second clamping plate 13, located at different positions on both sides of the force gauge base plate 9, can be adjusted independently according to the shape of the force gauge, ensuring the limiting use of different force gauges. The slide rod 10's side... The slot 15, with its inclined side set towards the center of the slide rod 10, allows the buckle 16 to automatically slide outward inside the first clamping plate 12 or the second clamping plate 13 when the first clamping plate 12 or the second clamping plate 13 is pushed towards the center of the force gauge base plate 9 along the slide rod 10. This oblique arrangement of the slot 15 and the buckle 16's contact surface ensures that the buckle 16 does not affect the inward pushing of the first clamping plate 12 or the second clamping plate 13, enabling rapid clamping of the force gauge. When the force gauge needs to be removed, the pull plate 17 on the outside of the first clamping plate 12 or the second clamping plate 13 is pulled outward, thereby disengaging the buckle 16 from the slot 15 and allowing the first clamping plate 12 or the second clamping plate 13 to slide outward for easy removal of the force gauge. Furthermore, the buckle 16 can automatically reset and engage with the slot 15 under the elastic action of the first spring 18, facilitating the limiting use of the first clamping plate 12 or the second clamping plate 13.

[0063] The above technical solution enables the force gauge to be quickly fixed by sliding the first clamping plate 12 and the second clamping plate 13 inward, which is convenient for installation and use of different types of force gauges and improves the efficiency of measurement and testing.

[0064] Among them: such as Figure 1 , Figure 2 , Figure 6 and Figure 7In the test piece base plate 19, an anti-slip pad 20 is attached to the surface. A first sliding groove 21 is symmetrically formed on the side of the test piece base plate 19. A first slider 22 is slidably connected inside the first sliding groove 21. An anti-slip block 28 protrudes inward from the side of the first sliding groove 21 to prevent slippage. The clamping mechanism includes a clamping plate 24, an anti-slip pad 25, a second spring 26, and a locking block 27. The clamping plate 24 is slidably connected to the outside of the vertical rod 23. An anti-slip pad 25 is fixedly connected to the bottom inner side of the clamping plate 24. The second spring 26 is sleeved on the outside of the vertical rod 23. The second spring 26 is installed between the clamping plate 24 and the test piece seat plate 19. The locking block 27 is eccentrically rotated and installed at the top of the vertical rod 23. The top side of the first slider 22 is provided with a lower limit plate 29 at equal intervals. The top side of the first slide groove 21 is provided with an upper limit plate 30 at equal intervals. The lower limit plate 29 and the upper limit plate 30 are engaged with each other.

[0065] In specific application scenarios, when fixing the circuit board, the circuit board is first placed on the surface of the test piece base plate 19 according to the measurement and testing direction. The first slider 22 slides inside the first groove 21, causing the vertical rod 23 and the pressure plate 24 to move to the side of the circuit board. The locking block 27 is rotated at the top of the vertical rod 23. Due to the eccentric mounting of the locking block 27 at the top of the vertical rod 23, the bottom end of the locking block 27 presses down on the top surface of the pressure plate 24, causing the pressure plate 24 to slide downwards on the outside of the vertical rod 23. The anti-slip pad 25 fixed to the inner bottom surface of the pressure plate 24 presses down on the circuit board. After the pressure plate 24 contacts the circuit board through the anti-slip pad 25, the continuous rotation of the locking block 27 causes the vertical rod 23 to slide downwards in the first groove 21. The internal sliding upwards, when the locking block 27 rotates completely downwards, the locking block 27 stably presses down on the pressure plate 24. The first slider 22 engages with the upper limit plate 30 set on the inner top surface of the first slide groove 21 through the lower limit plate 29 set on its top surface, so that the first slider 22 is limited inside the first slide groove 21, preventing it from sliding during measurement and testing. After the test is completed, the pressure plate 24 is released from pressure by the reverse rotation of the locking block 27. Under the elastic action of the anti-detachment block 28 sleeved on the outside of the vertical rod 23, the pressure plate 24 slides upwards and is lifted. Under the overall gravity of the first slider 22, the vertical rod 23 and the locking block 27, the first slider 22 descends, which facilitates the outward sliding of the pressure plate 24, thereby removing the circuit board.

[0066] The above technical solution allows for autonomous sliding adjustment and adaptability to different specifications and models of circuit boards, enabling adaptive limiting in different detection directions. This ensures stability, prevents slippage during measurement and testing, and guarantees the accuracy of measurement and testing.

[0067] Among them: such as Figure 2 and Figure 7In the process, the height adjustment mechanism includes a support rod 31, an adjusting rod 32, a worm gear 33, a worm 34, and a handwheel 35. The support rod 31 is fixedly connected to the bottom surface of the test piece seat plate 19 and is slidably connected inside the connecting frame 3. The adjusting rod 32 is rotatably installed in the middle of the connecting frame 3, and the top end of the adjusting rod 32 is threadedly connected to the support rod 31. The worm gear 33 is integrally fixed to the bottom of the adjusting rod 32, and the worm 34 is connected to the outside of the worm gear 33. The top end of the worm 34 is fixed with a handwheel 35 located outside the connecting frame 3, and the worm 34 is rotatably installed inside the connecting frame 3.

[0068] In specific application scenarios, by directly rotating the handwheel 35, the worm gear 34 is driven to rotate inside the connecting frame 3. Through the transmission between the worm gear 34 and the worm wheel 33, the adjusting rod 32 is driven to rotate. By utilizing the threaded transmission between the support rod 31 and the adjusting rod 32, the support rod 31 is raised and lowered inside the connecting frame 3, thereby adjusting the height of the test piece base plate 19. This allows for adaptive adjustment based on the height of the measuring point on the circuit board, ensuring the connector is level.

[0069] The above technical solution allows for adjustment of the circuit board mounting height according to actual metrological testing, thereby maintaining and improving the stability and accuracy of metrological testing.

[0070] Among them: such as Figure 1 , Figure 2 , Figure 8 and Figure 9 In this structure, the connecting frame 3 forms a sliding structure above the support base plate 1 through a sliding assembly, which is used to adjust the distance between it and the machine frame 2. The sliding assembly includes: a second sliding groove 37, a second slider 38, a telescopic rod 39, a guide rail 40, and a push-pull rod 41. The second sliding groove 37 is opened on the top left side of the support base plate 1. The second sliding groove 37 and the second slider 38 fixed on the bottom surface of the connecting frame 3 are correspondingly engaged and slidably connected. The telescopic rod 39 is fixedly installed on the top surface of the support base plate 1. The top end of the telescopic rod 39 is fixedly connected to the connecting frame 3. The guide rail 40 is fixedly installed inside the machine frame 2. The push-pull rod 41 is slidably connected inside the guide rail 40. The top end of the push-pull rod 41 is fixedly connected to the inner side of the connecting frame 3.

[0071] In specific application scenarios, during actual metrological testing, due to differences in the model and specifications of the force gauge, circuit board, and connector, as well as the different positions of the measuring points, after the metrological testing connection is completed, the position of the force gauge base plate 9 cannot be moved to the leftmost end of the lead screw 7, resulting in a smaller usable stroke. By extending the telescopic rod 39, the connecting frame 3 is pushed outward, causing the bottom of the connecting frame 3 to slide outward above the second slide groove 37 via the second slider 38. At the same time, the push-pull rod 41 fixed on the side of the connecting frame 3 is pulled outward inside the guide rail 40, which can maintain the relative stability between the connecting frame 3 and the machine frame 2, allowing the force gauge base plate 9 to move to the leftmost end of the lead screw 7, thus ensuring usable stroke. Simultaneously, by extending the telescopic rod 39, the connecting frame 3 and the circuit board slide together, which can pull the measuring rod, increasing the additional stroke and ensuring metrological testing for the maximum force.

[0072] The above technical solution allows for the separation design, adjusting the distance between the force gauge and the circuit board to ensure full utilization of the stroke, and also allows for the addition of extra stroke to ensure measurement and detection of the maximum force.
