Description

Technical Field

[0001] This invention relates to the field of testing fixture technology, specifically to a crystal oscillator testing fixture. Background Technology

[0002] A crystal oscillator, or simply crystal, is a quartz piezoelectric element that functions as a frequency oscillator in a circuit board. When subjected to an applied alternating electric field, the crystal oscillator will generate mechanical vibration. When the frequency of the alternating electric field is the same as the natural frequency of the crystal oscillator, the vibration will become very strong. This is a characteristic response of the crystal oscillator. After production, crystal oscillators need to be inspected using a testing fixture. The testing fixture is a standard testing device that detects the natural frequency of the crystal oscillator to check for manufacturing defects and flaws, in order to ensure that the performance of the crystal oscillator meets the requirements.

[0018] Beneficial effects

[0019] The present invention has the following beneficial effects:

[0020] (1) The crystal oscillator testing fixture is equipped with a transfer mechanism. The drive cylinder drives the rotating mechanism to contact the crystal oscillator through the connecting frame. At the same time, the crystal oscillator is pressed down by the buffer device. The transfer mechanism picks up the crystal oscillator. The motor output shaft drives the lead screw to rotate. The lead screw drives the drive cylinder to move through the movable frame, so that the crystal oscillator moves to the bottom of the testing table. The crystal oscillator is put down through the transfer mechanism. The crystal oscillator is tested by the probe. The testing fixture has a testing table and a probe. When testing the crystal oscillator, it can automatically load and unload the material, which improves the loading and unloading speed and thus improves the testing efficiency. It has the advantages of saving time and effort. It solves the problem that in general, after testing one crystal oscillator, it is necessary to manually replace the next crystal oscillator and test it again. It is inconvenient to automatically load and unload the crystal oscillator, which leads to cumbersome operation and time-consuming and labor-intensive manual loading and unloading.

[0021] (2) The crystal oscillator testing fixture, by setting up a storage box, the feeding spring resets and drives the push plate to reset. The push plate will drive multiple crystal oscillators to move, so that the first crystal oscillator moves to the surface of the first buffer plate. Then, the first crystal oscillator is transferred by the transfer mechanism. The feeding spring continues to reset and drives the next crystal oscillator to contact the surface of the first buffer plate. This reciprocating motion achieves the advantage that multiple crystal oscillators can be arranged and placed in the storage box, and the crystal oscillators are pushed to the transfer area by the push plate, thereby improving the feeding efficiency. It solves the problem that after the crystal oscillator is transferred by the transfer mechanism, it is still necessary to place the crystal oscillator in the transfer area for transfer, which is not convenient.

[0022] (3) The crystal oscillator testing fixture, by setting a limiting rod, the output end of the testing cylinder drives the testing frame to move, the testing frame drives the limiting rod to move through the connecting plate, the limiting rod moves along the inner side wall of the fixed ring, the testing frame drives the probe to contact the pin of the crystal oscillator, and at the same time the fixed plate at one end of the limiting rod contacts the fixed ring, the limiting rod limits the testing frame, thus achieving the advantage of limiting the probe while it contacts the crystal oscillator, and solving the problem that when the testing frame drives the probe to contact the crystal oscillator, the probe may squeeze the crystal oscillator, which may damage the crystal oscillator.

[0023] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0033] Please see Figures 1-6The present invention provides a technical solution: a crystal oscillator testing fixture, including a base 1, a motor 3 is provided on the surface of the base 1 through a fixing frame 2, a lead screw 4 is provided at one end of the output shaft of the motor 3, a drive cylinder 5 is provided on the surface of the lead screw 4 through a movable part, and a transfer mechanism is provided at the output end of the drive cylinder 5 through a connecting frame 6. The transfer mechanism is used to transfer the crystal oscillator.

[0034] A buffer device is provided on the surface of the base 1 via the detection platform 7, and a detection frame 9 is provided on the surface of the base 1 via the detection cylinder 8. A probe is provided on the surface of the detection frame 9.

[0035] Specifically, the transfer mechanism includes a fixed tube 10, a piston 11, a movable rod 12, a fixed plate 13, and a suction cup 14. Multiple fixed tubes 10 are provided, and each fixed tube 10 is fixedly installed on the inner side wall of the connecting frame 6. The piston 11 is movably connected to the inner side wall of the fixed tube 10. One end of the movable rod 12 is fixedly connected to the surface of the piston 11. The fixed plate 13 is fixedly sleeved on the surface of the drive cylinder 5. The other end of the movable rod 12 passes through the connecting frame 6 and the fixed plate 13 respectively. The movable rod 12 is T-shaped. The suction cup 14 is fixedly installed at one end of the fixed tube 10. The number of movable rods 12, pistons 11, and suction cups 14 are all adapted to the number of fixed tubes 10.

[0036] In this embodiment, the output end of the drive cylinder 5 drives the connecting frame 6 to press down. The connecting frame 6 drives the suction cup 14 to move towards the crystal oscillator through the fixed tube 10. The fixed tube 10 drives the movable rod 12 to move through the piston 11. The movable rod 12 moves along the inner wall of the fixed plate 13 until the suction cup 14 contacts the crystal oscillator. At the same time, the circular plate at the top of the movable rod 12 contacts the fixed plate 13, thereby limiting the movable rod 12. The movable rod 12 limits the piston 11 and the iron block 16. The output shaft of the drive cylinder 5 continues to drive the connecting frame 6 to press down, thereby squeezing the crystal oscillator. The crystal oscillator squeezes the first compression spring 23 through the first buffer plate 24. The connecting frame 6 drives the fixed tube 10 to move along the surface of the piston 11, thereby increasing the volume of the small amount of gas in the fixed tube 10 and decreasing the air pressure, while the external atmospheric pressure remains unchanged, thereby holding the crystal oscillator through the suction cup 14.

[0037] Specifically, an electromagnet 15 is fixedly installed on the inner wall of the fixed tube 10, an iron block 16 is fixedly installed on the surface of the piston 11, the electromagnet 15 is movably connected to the surface of the movable rod 12, and the iron block 16 is fixedly connected to the surface of the movable rod 12.

[0038] In this embodiment, the iron block 16 contacts the electromagnet 15, and when the electromagnet 15 is energized, the electromagnet 15 will fix the piston 11 through the iron block 16, preventing the crystal oscillator from falling off when the piston 11 is reset during operation.

[0039] Specifically, a reset spring 17 is provided inside the fixed tube 10. One end of the reset spring 17 is fixedly connected to the inner wall of the fixed tube 10, and the other end of the reset spring 17 is fixedly connected to the bottom of the piston 11.

[0040] In this embodiment, the connecting frame 6 drives the fixing tube 10 to move along the surface of the piston 11. At the same time, the movement of the fixing tube 10 stretches the reset spring 17, de-energizes the electromagnet 15, and the reset spring 17 drives the piston 11, thereby automatically disengaging the crystal oscillator from the chuck 14.

[0041] Specifically, a storage box 18 is provided on the surface of the base 1, and a push plate 20 is provided on the inner side wall of the storage box 18 via a feeding spring 19. Multiple push plates 20 are provided. One end of the feeding spring 19 is fixedly connected to the inner side wall of the storage box 18, and the other end of the feeding spring 19 is fixedly connected to the surface of the push plate 20. A cover plate 21 is movably provided on the surface of the storage box 18.

[0042] In this embodiment, after the placement plate 25 is placed into the storage box 18, the push plate 20 is released, the feeding spring 19 resets, and the push plate 20 is reset. The push plate 20 will drive multiple crystal oscillators to move, so that the first crystal oscillator moves to the surface of the first buffer plate 24. After the first crystal oscillator is moved for detection, the feeding spring 19 continues to reset, driving the second crystal oscillator to contact the surface of the first buffer plate 24, and so on.

[0043] Specifically, the buffer device includes a first compression spring 23, a first buffer plate 24, a second compression spring 30, and a second buffer plate 22. The first buffer plate 24 is movably connected to the inner wall of the storage box 18. One end of the first compression spring 23 is fixedly connected to the surface of the first buffer plate 24, and the other end of the first compression spring 23 is fixedly connected to the inner wall of the storage box 18. The second buffer plate 22 is movably connected to the inner wall of the detection table 7. One end of the second compression spring 30 is fixedly connected to the surface of the second buffer plate 22, and the other end of the second compression spring 30 is fixedly connected to the inner wall of the detection table 7. Multiple first compression springs 23 are provided and correspond one-to-one with the first buffer plate 24, and multiple second compression springs 30 are provided and correspond one-to-one with the second buffer plate 22.

[0044] In this embodiment, the output shaft of the drive cylinder 5 continues to drive the connecting frame 6 to press down, which will squeeze the crystal oscillator. The crystal oscillator squeezes the first compression spring 23 through the first buffer plate 24, thereby compressing the first compression spring 23. This allows the connecting frame 6 to continue moving when the suction cup 14 contacts the crystal oscillator, thereby holding the crystal oscillator through the piston 11.

[0045] Specifically, the inner wall of the storage box 18 is provided with a placement plate 25, and the push plate 20 is movably connected to the surface of the placement plate 25. The push plate 20 and the feeding spring 19 are both adapted to the number of placement plates 25.

[0046] In this embodiment, the placement plate 25 is removed from the surface of the storage box 18, the crystal oscillators are arranged and placed on the surface of the placement plate 25, and then the placement plate 25 is placed into the storage box 18. Multiple placement plates 25 can be prepared, and the crystal oscillators are placed on the surface of the placement plate 25 in advance. After use, the placement plate 25 without crystal oscillators and the placement plate 25 with crystal oscillators can be directly interchanged, thereby saving the material loading time and making it easier to place the untested crystal oscillators into the storage box 18.

[0047] Specifically, a limiting plate 26 is provided on the surface of the storage box 18 via a movable shaft, and the limiting plate 26 is movably connected to the bottom of the cover plate 21.

[0048] In this embodiment, the limiting plate 26 is rotated around the movable axis to separate the limiting plate 26 from the surface of the cover plate 21, and then the cover plate 21 is removed from the surface of the storage box 18. The cover plate 21 limits the placement plate 25 and the crystal oscillator. The limiting plate 26 facilitates the disassembly of the cover plate 21.

[0049] Specifically, the surface of the detection frame 9 is provided with a limiting rod 27 via a connecting plate, and the surface of the detection cylinder 8 is provided with a fixing ring 28. The limiting rod 27 is movably connected to the inner side wall of the fixing ring 28, and the limiting rod 27 is T-shaped.

[0050] In this embodiment, the output end of the detection cylinder 8 drives the detection frame 9 to move. The detection frame 9 drives the limiting rod 27 to move through the connecting plate. The limiting rod 27 moves along the inner side wall of the fixing ring 28. The detection frame 9 drives the probe to contact the crystal oscillator pin. At the same time, the fixing plate at one end of the limiting rod 27 contacts the fixing ring 28. The limiting rod 27 limits the detection frame 9 to prevent the probe from squeezing the crystal oscillator when the detection frame 9 drives the probe to contact the crystal oscillator, which may damage the crystal oscillator.

[0051] Specifically, a buffer spring 29 is sleeved on the surface of the limiting rod 27. One end of the buffer spring 29 is fixedly connected to the surface of the limiting rod 27, and the other end of the buffer spring 29 is fixedly connected to the surface of the fixing ring 28.

[0052] In this embodiment, the limiting rod 27 moves along the inner wall of the fixing ring 28 and simultaneously squeezes the buffer spring 29, causing the buffer spring 29 to compress, which can buffer the detection frame 9.

[0053] During operation, rotate the limiting plate 26 around the movable axis to disengage it from the surface of the cover plate 21. Then, remove the cover plate 21 from the surface of the storage box 18. Press the push plate 20 towards the feeding spring 19, compressing it and pushing it until it disengages from the placement plate 25. Remove the placement plate 25 from the surface of the storage box 18. Multiple placement plates 25 can be prepared. Place the crystal oscillator on the surface of the placement plate 25 in advance. After the placement plates 25 in the storage box 18 are used up, The placement plate 25 without a crystal oscillator and the placement plate 25 with a crystal oscillator can be directly interchanged, thereby saving the material loading time. After the placement plate 25 is placed into the storage box 18, the push plate 20 is released, the loading spring 19 is reset, and the push plate 20 is reset. The push plate 20 will drive multiple crystal oscillators to move, so that the crystal oscillators away from the push plate 20 move to the surface of the first buffer plate 24. Then the cover plate 21 is placed on the surface of the storage box 18, and the limiting plate 26 is rotated around the movable axis so that the limiting plate 26 contacts the surface of the cover plate 21, thereby fixing the cover plate 21.

[0054] One end of the lead screw 4 is connected to the output shaft of the motor 3, and the other end of the lead screw 4 is connected to the inner wall of the fixed frame 2 through a connecting shaft. The inner wall of the movable part is provided with an internal thread, and the lead screw 4 is threadedly connected to the movable part. A guide plate is provided on the top of the fixed frame 2, and the movable part is movably connected to the guide plate. When the motor 3 is started, the output shaft of the motor 3 drives the lead screw 4 to rotate. The rotation of the lead screw 4 drives the movable part to move through the thread. The movable part moves along the guide plate on the top of the fixed frame 2, thereby guiding and limiting the movable part. The movable part drives the connecting frame 6 and the fixed plate 13 to move through the drive cylinder 5. The suction cup 14 moves to the top of the crystal oscillator. When the motor 3 is turned off, the drive cylinder 5 is started. The output end of the drive cylinder 5 drives the connecting frame 6 to press down. The connecting frame 6 moves through the fixed tube 10. The piston 11 moves the suction cup 14 towards the crystal oscillator, and the piston 11 fits tightly against the inner wall of the fixed tube 10. The fixed tube 10 then drives the movable rod 12 via the piston 11. The movable rod 12 passes through the fixed plate 13 and moves along the inner wall of the fixed plate 13. The fixed plate 13 is fixedly connected to the cylinder section of the drive cylinder 5. When the output end of the drive cylinder 5 is pressed down, the drive cylinder 5 as a whole does not move, thus the fixed plate 13 does not move with the connecting frame 6. The movement continues until each suction cup 14 contacts the corresponding crystal oscillator. Simultaneously, the circular plate at the top of the movable rod 12 contacts the fixed plate 13, thus limiting the movable rod 12. The movable rod 12 limits the piston 11 and the iron block 16. The output shaft of the drive cylinder 5 continues to drive the connecting frame 6 downwards.The connecting frame 6 drives the fixing tube 10 to move along the surface of the piston 11. Simultaneously, the movement of the fixing tube 10 stretches the return spring 17, which in turn compresses the crystal oscillator. The crystal oscillator, through the first buffer plate 24, compresses the first compression spring 23, thus increasing the volume of the cavity at the bottom of the piston 11 and decreasing the air pressure, while the external atmospheric pressure remains unchanged. This allows each suction cup 14 to hold its corresponding crystal oscillator, ensuring tight contact and preventing air leakage. Simultaneously, the iron block 16 contacts the electromagnet 15, energizing it. The electromagnet 15 then fixes the piston 11 through the iron block 16, driving the output end of the cylinder 5 to rise and reset. At the same time, the connecting frame 6 drives the fixing tube 10 to move, and the fixing tube 10, through the suction cups 14, causes the crystal oscillator to detach from the first buffer plate 24, resetting the first compression spring 23. The first buffer plate 24 is reset by the piston 11, and the fixed tube 10 drives the movable rod 12 to move along the inner wall of the fixed plate 13. At the same time, under the action of the reset spring 19, the push plate 20 is driven to push the next crystal oscillator onto the surface of the first buffer plate 24. The motor 3 is started, and the motor 3 drives the lead screw 4 to rotate. The lead screw 4 drives the movable part to move to the top of the second buffer plate 22 on the surface of the crystal oscillator and the detection table 7. The output end of the drive cylinder 5 is pressed down, de-energizing the electromagnet 15. The electromagnet 15 and the iron block 16 are magnetically disconnected. At the same time, the reset spring 17 resets and pulls the piston 11 to move down along the inner wall of the fixed tube 10 to the reset position. The piston 11 drives the iron block 16 to disengage from the electromagnet 15, thereby disengaging the crystal oscillator from the suction cup 14 and making the crystal oscillator contact the second buffer plate 22.

[0055] The detection cylinder 8 is activated, and its output drives the detection frame 9 to move. The detection frame 9, through the connecting plate, drives the limiting rod 27 to move. The limiting rod 27 moves along the inner wall of the fixed ring 28, simultaneously compressing the buffer spring 29 to buffer the detection frame 9. The detection frame 9 drives the probe to contact the crystal oscillator's pins. At the same time, the fixed plate at one end of the limiting rod 27 contacts the fixed ring 28, limiting the detection frame 9 to prevent the probe from pressing against the crystal oscillator and potentially damaging it. At this time, the detection analyzer electrically connected to the probe can detect the crystal oscillator's natural frequency. After the detection is completed, the drive cylinder 5 is pressed down, driving the suction cup 14 to contact the crystal oscillator. At the same time, the circular plate at the top of the movable rod 12 contacts the fixed plate 13, thereby limiting the piston 11 and the iron block 16 through the movable rod 12, and driving the cylinder... The output shaft 5 continues to drive the connecting frame 6 to press down. The connecting frame 6 drives the fixed tube 10 to move along the surface of the piston 11. At the same time, the movement of the fixed tube 10 stretches the reset spring 17, which squeezes the crystal oscillator. The crystal oscillator squeezes the second compression spring 30 through the second buffer plate 22, thereby compressing the second compression spring 30. The crystal oscillator is then held by the suction cup 14. At the same time, the iron block 16 contacts the electromagnet 15, energizing the electromagnet 15. The electromagnet 15 will fix the piston 11 through the iron block 16, driving the output end of the cylinder 5 to rise and reset. At the same time, the connecting frame 6 drives the fixed tube 10 to move. The fixed tube 10 drives the crystal oscillator to disengage from the second buffer plate 22 through the suction cup 14. The motor 3 is started. The output shaft of the motor 3 drives the lead screw 4 to rotate, transporting the crystal oscillator to the unloading area on the surface of the base 1. The motor 3 is turned off. The cylinder 5 is driven to press down, de-energizing the electromagnet 15, thereby disengaging the crystal oscillator from the suction cup 14, completing the unloading process. This process is repeated.
