A solid-state drive plug-in durability testing fixture

Abstract

This utility model relates to the field of durability testing technology, specifically a solid-state drive (SSD) insertion / removal durability testing fixture. It includes a test base, a feeding mechanism, a gripping mechanism, and an insertion / removal mechanism. The feeding mechanism is mounted on the surface of the test base and includes a conveyor frame, a conveyor belt, and a conveyor motor. It can quickly and accurately align the gripping claw with the SSD under test, and the gripping force can be naturally adjusted according to the spring compression. This avoids damage to the SSD casing caused by rigid gripping while ensuring effective clamping of the SSD. The pawl, under the elastic force of the second spring, continuously engages with the ratchet tooth groove, forming a one-way locking structure. This completely restricts gear reversal, thereby locking the position of the pressure plate and ensuring that the gripping claw maintains a stable clamping force. Even if the electric telescopic rod experiences slight extension or contraction, or if the equipment vibrates during operation, it will not loosen, providing absolutely stable gripping assurance for subsequent lifting, conveying, and other processes.

Description

Technical Field

[0001] This utility model relates to the field of durability testing technology, specifically to a solid-state drive plug-in durability testing fixture. Background Technology

[0002] In the production and quality inspection of solid-state drives (SSDs), plug-in durability testing is a core item for evaluating the reliability and lifespan of their interfaces, which is directly related to the stability of the product in actual use. With the iteration of storage technology and the growth of market demand, the production scale of SSDs continues to expand, and the requirements for their testing efficiency and accuracy are becoming increasingly stringent.

[0003] Existing solid-state drive (SSD) plug-in durability testing fixtures have the following shortcomings:

[0004] 1. Traditional test fixtures mostly use rigid gripping structures, and the gripping force cannot be adaptively adjusted. Not only is it easy to damage the hard drive shell due to excessive clamping, but it is also difficult to adapt to solid-state drives of different thicknesses. In addition, the locking mechanism after gripping is unreliable. During lifting and transfer, it is easily affected by equipment vibration or slight expansion and contraction of drive components, which can cause the solid-state drive to loosen or slip, resulting in hardware impact damage and affecting the integrity of the test sample.

[0005] 2. Staff need to place the solid-state drives one by one in the test position and manually align them. This not only increases labor costs, but also makes it difficult to accurately control the core parameters such as force, speed and frequency due to manual insertion and removal. The force may decrease due to operator fatigue, or the test conditions may vary due to different operating habits, resulting in large fluctuations in durability data, which cannot provide a reliable basis for product quality assessment. Utility Model Content

[0006] The purpose of this invention is to provide a solid-state drive (SSD) plug-in durability testing fixture.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A solid-state drive (SSD) insertion / removal durability testing fixture is provided, including a test base, a feeding mechanism, a gripping mechanism, and an insertion / removal mechanism. The feeding mechanism is mounted on the surface of the test base and includes a conveyor frame, a conveyor belt, and a conveyor motor. The conveyor frame is fixed to the surface of the test base, and the conveyor belt is connected to the inside of the conveyor frame via conveyor rollers. The conveyor motor is fixed to the surface of the conveyor frame and connected to the conveyor belt via conveyor rollers. The surface of the conveyor belt has several sets of equidistantly arranged SSD placement slots. The gripping mechanism is mounted on the surface of the test base and includes a support frame, a threaded seat, a fixed seat, an electric telescopic rod, a lifting seat, and a gripper. The gripper consists of two sets of support frames fixed to the surface of the test base near the output end of the feeding mechanism. A threaded seat is slidably connected to the surface of the limiting rod between the two sets of support frames. A fixed seat is fixed to the surface of the threaded seat. An electric telescopic rod is fixed to the surface of the fixed seat. A lifting seat is fixed to the output end of the electric telescopic rod. The gripper is arranged in a ring array and hinged to the surface of the lifting seat. The insertion / removal mechanism is installed on the surface of the test base. The insertion / removal mechanism includes a push rod, a positioning frame, and a test plug. Two sets of positioning frames are fixed to the surface of the feeding mechanism conveyor frame near the gripper. The push rod is slidably connected inside the positioning frame. The test plug is fixed between the two sets of push rods.

[0009] Preferably, the gripping mechanism further includes a hinge rod, a pressure plate, a first spring, and a push plate. One end of the hinge rod is hinged to the middle of the gripper claw via a hinge. The pressure plate is located directly below the lifting seat, and the surface of the pressure plate is hinged to the other end of the hinge rod. The first spring is fixed between the pressure plate and the lifting seat. The push plate is fixed to the bottom of the pressure plate and can drive the pressure plate to move. The gripper claw is driven to close via the hinge rod. An anti-slip pad is fixed on the inner side of the gripper claw to prevent the solid-state drive from slipping during the gripping process.

[0010] Preferably, a shifting screw is rotatably connected between the two sets of support frames, and the shifting screw is threadedly connected to the threaded seat. A shifting motor is fixed to the outside of one set of support frames. The output shaft of the shifting motor is fixedly connected to one end of the shifting screw. Starting the shifting motor can drive the shifting screw to rotate, thereby driving the threaded seat to slide along the limiting rod between the support frames, so as to realize the horizontal position adjustment of the gripping mechanism.

[0011] Preferably, the gripping mechanism further includes a rack, a gear, a rotating shaft, a ratchet, a pawl, and a second spring. The rack is fixed to the surface of the pressure plate. The rotating shaft is rotatably connected to the lower surface of the lifting seat via a bearing bracket. The gear and ratchet are both fixed to the surface of the rotating shaft, and the gear meshes with the rack. The pawl is hinged to the lower surface of the lifting seat via a hinge, and the pawl engages with the tooth groove of the ratchet. The second spring is fixed between the pawl and the lifting seat. The elastic force of the second spring keeps the pawl engaged with the ratchet, thus preventing the gear from reversing.

[0012] Preferably, an electromagnet is fixed at the bottom of the lifting seat, and a magnetic suction frame is provided directly below the electromagnet. The magnetic suction frame is hinged to the surface end of the pawl. When the gripper needs to release the solid-state drive it has gripped, the electromagnet is energized to generate magnetism, which attracts the magnetic suction frame and causes the electromagnet to disengage from the ratchet. Under the action of the first spring's rebound force, the gripper can release the solid-state drive from its grip.

[0013] Preferably, the insertion / removal mechanism further includes a fixed frame, a swing arm, a positioning wheel, a cam, an insertion / removal motor, and a tension spring. The fixed frame is fixed to the surface of the test base. The middle part of the swing arm is hinged to the top of the fixed frame via a hinge. The positioning wheel is rotatably connected to one end of the swing arm via a bearing. The insertion / removal motor is fixed to the surface of the fixed frame. The cam is fixed to the output shaft surface of the insertion / removal motor, and the positioning wheel is in contact with the surface of the cam. The tension spring is fixed between the swing arm and the fixed frame. When the insertion / removal motor is started, it drives the cam to rotate. With the cooperation of the cam and the tension spring, the swing arm is driven to swing back and forth around the hinge.

[0014] Preferably, a lifting frame is hinged to the end of the swing arm away from the positioning wheel, and the push rod is fixed to the surface of the lifting frame. The lifting frame drives the push rod to slide back and forth along the positioning frame to realize the automatic plugging and unplugging action of the test plug and the solid-state drive. At the same time, the inner side of the positioning frame is provided with a guide groove that matches the lifting frame to limit the movement direction of the lifting frame and prevent the push rod from deviating and causing misalignment between the test plug and the solid-state drive.

[0015] Preferably, a baffle plate is provided in front of the fixed base facing the input end of the feeding mechanism to block solid-state drives that are not gripped on the surface of the conveyor belt. A touch switch is fixed inside the fixed base near the baffle plate, and a third spring is fixed between the baffle plate and the touch switch.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model discloses a solid-state drive (SSD) insertion / removal durability testing fixture. It enables the gripper to quickly and accurately align with the SSD under test, and the gripping force is naturally adjusted according to the spring compression. This avoids damage to the SSD casing caused by rigid gripping and ensures effective clamping for SSDs of different thicknesses. The pawl, under the elastic force of the second spring, continuously engages with the ratchet teeth, forming a one-way locking structure. This completely prevents gear reversal and locks the position of the pressure plate, ensuring the gripper maintains a stable clamping force. Even with slight extension or retraction of the electric telescopic rod or vibrations during equipment operation, it will not loosen, providing absolutely stable gripping assurance for subsequent lifting and transfer processes. The locked state of the gripper is maintained at all times, ensuring stable clamping of the SSD and completely eliminating hardware damage caused by loosening or slippage during transfer, thus guaranteeing the integrity of the test sample.

[0018] 2. This utility model discloses a solid-state drive (SSD) insertion / removal durability testing fixture. A blocking plate physically intercepts the SSD during transport, while a hard drive placement slot on the conveyor belt provides double protection for the SSD's positional stability in the gripping area, preventing it from shifting due to inertia. Simultaneously, the SSD's thrust triggers a touch switch via compression of a third spring, creating a linkage mechanism from mechanical obstruction to signal feedback. This accurately identifies the SSD's position, ensuring the conveyor motor pauses promptly upon reaching the designated gripping point, preventing gripping failures due to positioning deviations from the outset. From the blocking plate interception and spring compression triggering the switch, to the control system activating the positioning motor to adjust the position and drive the gripping action, and finally to the pawl and ratchet locking the gripping state, the entire process requires no manual intervention, achieving a fully automated closed loop. This not only eliminates the tedious steps of manual calibration and support but also avoids individual differences in human operation, ensuring consistent gripping process, force, and accuracy for each SSD, providing a prerequisite guarantee for the reliability of subsequent test data.

[0019] 3. This utility model provides a solid-state drive (SSD) plug-in / plug durability testing fixture that ensures perfect alignment between the SSD interface and the central axis of the test plug. Precise initial alignment provides a prerequisite for subsequent plug-in / plug operations, reducing interface wear and pin bending caused by misalignment from the outset, thus extending the service life of both the test fixture and the SSD. The plug-in / plug process is powered by a plug-in / plug motor, which drives the swing arm to reciprocate through the cooperation of a cam and a tension spring. The entire action chain is mechanically linked, requiring no manual intervention. Core test parameters such as plug-in / plug force, speed, and frequency are entirely determined by the mechanical structure, maintaining long-term stability. It avoids force attenuation due to human fatigue and parameter differences caused by individual operating habits. Standardized plug-in / plug operations ensure that every test is conducted under the same conditions, providing a reliable basis for horizontal comparison and analysis of durability data.

[0020] 4. The solid-state drive (SSD) insertion and removal durability testing fixture of this utility model forms a closed-loop automated process from SSD transfer and alignment to the start-up of the insertion and removal motor to drive reciprocating insertion and removal, and then to automatic pause after the preset number of times. It eliminates the need for manual operation between the grabbing, transfer, and insertion / removal steps. Compared with the limited number of tests that can be completed for a single sample by manual operation, it not only completely frees up labor costs, but also improves testing efficiency several times and significantly shortens the product testing cycle.

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0032] Reference Figures 1 to 7The solid-state drive (SSD) insertion / removal durability testing fixture shown includes a test base 1, a feeding mechanism 2, a gripping mechanism 3, and an insertion / removal mechanism 25. The feeding mechanism 2 is mounted on the surface of the test base 1 and includes a conveyor frame, a conveyor belt, and a conveyor motor. The conveyor frame is fixed to the surface of the test base 1, and the conveyor belt is connected to the inside of the conveyor frame via conveyor rollers. The conveyor motor is fixed to the surface of the conveyor frame and connected to the conveyor belt via conveyor rollers. The surface of the conveyor belt has several sets of equidistantly arranged hard drive placement slots. The gripping mechanism 3 is mounted on the surface of the test base 1 and includes a support frame 4, a threaded seat 7, a fixed seat 8, an electric telescopic rod 9, a lifting seat 10, and gripping claws 11. Two sets of support frames 4... The threaded seat 7 is slidably connected to the surface of the limiting rod between the two sets of support frames 4, and the fixed seat 8 is fixed to the surface of the threaded seat 7. The electric telescopic rod 9 is fixed to the surface of the fixed seat 8, and the lifting seat 10 is fixed to the output end of the electric telescopic rod 9. The gripping claw 11 is hinged to the surface of the lifting seat 10 in a ring array. The plug-in mechanism 25 is installed on the surface of the test base 1. The plug-in mechanism 25 includes a push rod 33, a positioning frame 34 and a test plug 35. The two sets of positioning frames 34 are fixed to the surface of the conveyor frame of the feeding mechanism 2 near the gripping claw 11. The push rod 33 is slidably connected inside the positioning frame 34, and the test plug 35 is fixed between the two sets of push rods 33.

[0033] Reference Figure 3 and Figure 4As shown, the gripping mechanism 3 also includes a hinge rod 12, a pressure plate 13, a first spring 14, and a push plate 15. One end of the hinge rod 12 is hinged to the middle of the gripper 11 via a hinge. The pressure plate 13 is located directly below the lifting seat 10, and the surface of the pressure plate 13 is hinged to the other end of the hinge rod 12. The first spring 14 is fixed between the pressure plate 13 and the lifting seat 10. The push plate 15 is fixed to the bottom of the pressure plate 13 and can drive the pressure plate 13 to move. The gripper 11 is driven to close by the hinge rod 12. An anti-slip pad 16 is fixed on the inner side of the gripper 11 to prevent the solid-state drive from slipping during the gripping process. After receiving the signal from the touch switch 37, the control system starts the shifting motor 6. The shifting motor 6 drives the shifting screw 5 between the two sets of support frames 4 to rotate. As the threaded seat 7 is threadedly connected to the shifting screw 5 and guided by the limiting rod between the support frame 4, the threaded seat 7 slides horizontally along the limiting rod, thereby driving the fixed seat 8, electric telescopic rod 9 and other components to move, so that the gripping claw 11 under the lifting seat 10 is precisely aligned with the blocked solid-state drive. After the gripping position is calibrated, the electric telescopic rod 9 starts and extends, pushing the lifting seat 10 and the gripping claw 11, pressure plate 13 and other components at the bottom to move downward. When the push plate 15 contacts the surface of the solid-state drive, the electric telescopic rod 9 continues to extend, and the pressure plate 13 moves upward under the reaction force, compressing the first spring 14. The pressure plate 13 drives the gripping claw 11 to rotate inward around the hinge point through the hinge rod 12, realizing closure and clamping the solid-state drive. The anti-slip pad 16 on the inner side of the gripping claw 11 increases the friction and prevents slippage.

[0034] Reference Figure 1 and Figure 2 As shown, a shifting screw 5 is rotatably connected between the two sets of support frames 4, and the shifting screw 5 is threadedly connected to the threaded seat 7. A shifting motor 6 is fixed to the outside of one set of support frames 4. The output shaft of the shifting motor 6 is fixedly connected to one end of the shifting screw 5. Starting the shifting motor 6 can drive the shifting screw 5 to rotate, thereby driving the threaded seat 7 to slide along the limiting rod between the support frames 4, realizing the horizontal position adjustment of the gripping mechanism 3. After the gripping action is completed, the electric telescopic rod 9 retracts, driving the gripping claw 11 and the solid-state drive to rise to a safe height. Then the shifting motor 6 starts again, driving the threaded seat 7 to slide along the limiting rod, moving the solid-state drive to directly above the test plug 35 of the plug-in / plug-out mechanism 25, completing the alignment before testing.

[0035] Reference Figure 4 , Figure 5 and Figure 6As shown, the gripping mechanism 3 also includes a rack 17, a gear 18, a rotating shaft 19, a ratchet 20, a pawl 21, and a second spring 22. The rack 17 is fixed to the surface of the pressure plate 13. The rotating shaft 19 is rotatably connected to the lower surface of the lifting seat 10 via a bearing bracket. The gear 18 and the ratchet 20 are both fixed to the surface of the rotating shaft 19, and the gear 18 meshes with the rack 17. The pawl 21 is hinged to the lower surface of the lifting seat 10 via a hinge, and the pawl 21 engages with the tooth groove of the ratchet 20. The second spring 22 is fixed between the pawl 21 and the lifting seat 10. During this period, the elastic force of the second spring 22 keeps the pawl 21 engaged with the ratchet 20, which is used to limit the reverse rotation of the gear 18. At the same time, the rack 17 on the pressure plate 13 rises with the pressure plate 13, driving the gear 18 that meshes with it to rotate. The gear 18 drives the ratchet 20 to rotate synchronously through the rotating shaft 19. Under the action of the elastic force of the second spring 22, the pawl 21 is always engaged with the tooth groove of the ratchet 20, limiting the reverse rotation of the ratchet 20. In turn, the gear 18 and the rack 17 lock the position of the pressure plate 13, ensuring that the gripper 11 remains in a clamped state.

[0036] Reference Figure 3 , Figure 4 and Figure 6 As shown, an electromagnet 24 is fixed to the bottom of the lifting seat 10. A magnetic suction bracket 23 is located directly below the electromagnet 24 and is hinged to the surface end of the pawl 21. When the gripper 11 needs to release the solid-state drive it has gripped, the electromagnet 24 is energized to generate magnetism, which attracts the magnetic suction bracket 23 and causes the electromagnet 24 to disengage from the ratchet 20. Under the rebound force of the first spring 14, the gripper 11 can release the solid-state drive. After reaching the preset number of test cycles, the plug-in / plug-out motor 30 stops running, and the test plug-in / plug-out connector 35 returns to the unplugged state. The control system energizes the electromagnet 24 at the bottom of the lifting seat 10. The electromagnet 24 generates magnetic attraction to the magnetic suction frame 23, which drives the pawl 21 to rotate around the hinge point, disengaging from the ratchet 20 and releasing the lock. Under the rebound force of the first spring 14, the pressure plate 13 moves downward, driving the gripper 11 to rotate outward through the hinge rod 12, thus opening. At the same time, the pressure plate 13 drives the rack 17 to move downward, and the gear 18 and ratchet 20 rotate in the opposite direction with the rack 17. Subsequently, the electric telescopic rod 9 extends, placing the solid-state drive at the designated unloading position of the feeding mechanism 2.

[0037] Reference Figure 7As shown, the insertion / removal mechanism 25 also includes a fixed frame 26, a swing arm 27, a positioning wheel 28, a cam 29, an insertion / removal motor 30, and a tension spring 31. The fixed frame 26 is fixed to the surface of the test base 1. The middle part of the swing arm 27 is hinged to the top of the fixed frame 26. The positioning wheel 28 is rotatably connected to one end of the swing arm 27 via a bearing. The insertion / removal motor 30 is fixed to the surface of the fixed frame 26. The cam 29 is fixed to the output shaft surface of the insertion / removal motor 30, and the positioning wheel 28 is in contact with the surface of the cam 29. The tension spring 31 is fixed between the swing arm 27 and the fixed frame 26. When the insertion / removal motor 30 is started, it drives the cam 29 to rotate. With the cooperation of spring 31, after the drive arm 27 reciprocates around the hinge to complete the alignment, the plug-in / plug-out motor 30 of the plug-in / plug-out mechanism 25 starts, driving the cam 29 fixed on the output shaft to rotate. When the protruding end of the cam 29 contacts the positioning wheel 28 at one end of the arm 27, it pushes the arm 27 to swing upward around the hinge at the top of the fixed frame 26, stretching the tension spring 31. The other end of the arm 27 drives the push rod 33 to slide upward along the guide groove of the positioning frame 34 through the lifting frame 32, so that the test plug 35 is inserted into the interface of the solid-state drive. After the protruding end of the cam 29 rotates past the positioning wheel 28, the arm 27 returns to its original position downward under the tension of the tension spring 31.

[0038] Reference Figure 7 As shown, a lifting frame 32 is hinged to the end of the swing arm 27 away from the positioning wheel 28. The push rod 33 is fixed to the surface of the lifting frame 32. The lifting frame 32 drives the push rod 33 to slide back and forth along the positioning frame 34, realizing the automatic insertion and removal of the test plug 35 and the solid-state drive. At the same time, the inner side of the positioning frame 34 is provided with a guide groove that matches the lifting frame 32, which is used to limit the movement direction of the lifting frame 32 and prevent the push rod 33 from deviating and causing misalignment between the test plug 35 and the solid-state drive. The lifting frame 32 drives the push rod 33 to slide down along the guide groove, so that the test plug 35 is pulled out from the solid-state drive interface. The plug-in motor 30 runs continuously. The cam 29 and the tension spring 31 work together to drive the swing arm 27 to swing back and forth, realizing the automatic insertion and removal of the test plug 35 and the solid-state drive, completing the durability test. The guide groove on the inner side of the positioning frame 34 can limit the movement direction of the lifting frame 32 and prevent the push rod 33 from deviating and causing misalignment.

[0039] Reference Figure 2 and Figure 7As shown, a baffle plate 36 is provided in front of the fixed base 8 facing the input end of the feeding mechanism 2 to block solid-state drives (SSDs) that are not gripped on the conveyor belt surface. A touch switch 37 is fixed inside the fixed base 8 near the baffle plate 36. A third spring 38 is fixed between the baffle plate 36 and the touch switch 37. After the conveyor motor of the feeding mechanism 2 is started, it drives the conveyor belt to run along the conveyor frame through the conveyor roller. The operator places the SSDs to be tested one by one into the hard drive placement slots on the surface of the conveyor belt. The hard drive placement slots limit the SSDs to prevent them from shifting during transport. When the SSD moves with the conveyor belt to below the gripping mechanism 3, the baffle plate 36 in front of the fixed base 8 forms a physical block to prevent it from continuing to be transported. The thrust of the SSD compresses the third spring 38 between the baffle plate 36 and the touch switch 37 until the baffle plate 36 triggers the touch switch 37. The touch switch 37 sends a signal to the control system to indicate that the SSD has reached the designated gripping position, and the conveyor motor stops running.

[0040] Reference Figure 5 and Figure 6 As shown, when the electromagnet 24 is de-energized, the magnetic chuck 23 is reset under the gravity of the pawl 21 and the action of the second spring 22, waiting for the next gripping. After a single test is completed, the conveyor motor of the feeding mechanism 2 restarts and transports the next solid-state drive to be tested to the gripping position. The blocking plate 36 and the touch switch 37 trigger signals again, and the equipment repeats the above feeding, gripping, transferring, plugging and unplugging, and releasing process to realize continuous automated solid-state drive plugging and unplugging durability testing.
