Description

Technical Field

[0001] This invention relates to the field of computer hot-plug testing technology, and more specifically to a computer hot-plug testing device. Background Technology

[0002] Hot-plugging tests during computer cold starts are a key quality control item for verifying the stability of external storage device recognition, port electrical withstand capability, and system reliability during overall system operation. They are widely used in computer factory testing. With increasing testing demands, using automated devices to replace manual labor for repetitive plugging and unplugging operations has become the mainstream testing method in the industry.

[0003] For example, a computer hot-plug testing device with announcement number CN119806943A uses multiple adjustment mechanisms to adjust the position of a USB flash drive in multiple planes, adapting to the interface positions of different computer models and possessing good versatility. However, when batch testing computers of the same specifications, this solution requires a separate clamping and fixing process before starting the insertion test. Clamping and insertion are two independent drive processes, with a waiting time between the processes. It is impossible to simultaneously complete positioning, clamping, and device insertion in a single feed action, resulting in a long test cycle per unit. The continuity and efficiency of batch testing need to be improved.

[0004] Therefore, the present invention provides a computer hot-plug testing device to solve the above-mentioned problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a computer hot-swap testing device to solve the problems of long single-unit testing cycle and low batch testing efficiency when the clamping and fixing and insertion processes are executed independently and the continuity of operation is insufficient during the batch hot-swap testing of computers of the same specifications.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A computer hot-swap testing device includes a testing platform and a USB flash drive. A U-shaped frame is fixedly connected to the upper surface of the testing platform. A threaded plate is slidably disposed on the upper surface of the testing platform. Two connecting rods and two first wedge plates are fixedly connected to the side of the threaded plate near the U-shaped frame. A movable plate is fixedly connected to the other end of each connecting rod. The movable plate is connected to the USB flash drive through an adjustment mechanism. A pushing mechanism is disposed on the side of the movable plate near the U-shaped frame. Second springs are fixedly connected to both side walls of the U-shaped frame. A clamping plate is fixedly connected to the other end of each second spring. A second wedge plate is fixedly connected to the side of each clamping plate that is far away from each other, and the second wedge plate corresponds one-to-one with the first wedge plate.

[0008] Preferably, the upper surface of the testing platform is fixedly connected to two support plates, and a lead screw is rotatably installed between the two support plates. The threaded plate is threaded to the outside of the lead screw. One of the support plates has a through hole for the connecting rod to pass through, and the outer surface of the other support plate is fixedly installed with a motor. The output end of the motor is fixedly connected to one end of the lead screw.

[0009] Preferably, the propulsion mechanism includes a piston cylinder fixedly connected to the outer surface of the movable plate, a first spring fixedly connected inside the piston cylinder, a piston rod fixedly connected to the other end of the first spring, and the other end of the piston rod slidingly through the piston cylinder and fixedly connected to the propulsion plate.

[0010] Preferably, the side of the push plate near the U-shaped frame is provided with a smooth layer, and the sides of the two clamping plates that are close to each other are provided with an anti-slip layer.

[0011] Preferably, a plurality of support strips arranged at equal intervals are fixedly installed on the upper surface of the testing platform.

[0012] Preferably, the bottom surfaces of the two second wedge plates are fixedly connected to sliding columns, and the other ends of the two sliding columns are slidably connected inside the detection table.

[0013] Preferably, the adjustment mechanism includes a first U-shaped plate fixedly connected to one side of the movable plate, a first threaded rod rotatably mounted inside the first U-shaped plate, a first knob fixedly connected to one end of the first threaded rod, a first threaded block threadedly connected to the outer surface of the first threaded rod, and the first threaded block slidably connected inside the first U-shaped plate.

[0014] Preferably, a connecting plate is fixedly connected to the outer surface of the first threaded block, and the side of the connecting plate away from the first threaded block slides through the moving plate and is fixedly connected to the second U-shaped plate.

[0015] Preferably, a second threaded rod is rotatably mounted inside the second U-shaped plate, a second knob is fixedly connected to one end of the second threaded rod, a second threaded block is threadedly connected to the outer surface of the second threaded rod, and the second threaded block is slidably connected inside the second U-shaped plate.

[0016] Preferably, a third U-shaped plate is fixedly connected to the outer surface of the second threaded block, a third threaded rod is rotatably installed inside the third U-shaped plate, a third knob is fixedly connected to one end of the third threaded rod, a third threaded block is threadedly connected to the outer surface of the third threaded rod, the third threaded block is slidably connected inside the third U-shaped plate, and the USB flash drive is fixedly installed on one side of the third threaded block.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This invention adopts a single-drive source linkage structure design. The screw drives the threaded plate to feed linearly in one go, which can sequentially trigger the continuous actions of computer push positioning, two-sided centering clamping and USB flash drive insertion. It integrates the traditional step-by-step fixed process and insertion process into a single feed process, eliminating the waiting interval between multiple processes, significantly shortening the test cycle of a single computer, and effectively improving the work efficiency of batch testing of equipment of the same specifications.

[0019] 2. By setting an adjustment mechanism, the present invention can flexibly adjust the spatial installation position of the USB flash drive to adapt to different interface positions of the same size computer. At the same time, the wedge-shaped linkage clamping method has an automatic centering effect. Combined with the elastic buffer structure composed of piston cylinder and first spring, it can avoid rigid impact during the insertion process. While ensuring test stability and equipment safety, it expands the adaptability range of the device and reduces the debugging cost of testing different models. Attached Figure Description

[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0028] As attached Figures 1-6 As shown, a computer hot-plug testing device includes a testing platform 1 and a USB flash drive 29. A U-shaped frame 2 is fixedly connected to the upper surface of the testing platform 1, and a threaded plate 7 is slidably arranged on the upper surface of the testing platform 1. Two connecting rods 8 and two first wedge plates 14 are fixedly connected to the side of the threaded plate 7 near the U-shaped frame 2. A moving plate 9 is fixedly connected to the other end of the connecting rods 8. The moving plate 9 is connected to the USB flash drive 29 through an adjustment mechanism. A pushing mechanism is arranged on the side of the moving plate 9 near the U-shaped frame 2. Second springs 15 are fixedly connected to both side walls of the U-shaped frame 2. A clamping plate 16 is fixedly connected to the other end of the second spring 15. A second wedge plate 17 is fixedly connected to the side of the two clamping plates 16 that are far apart from each other, and the second wedge plate 17 corresponds one-to-one with the first wedge plate 14. This structure relies on the linear movement of the threaded plate 7 to synchronously drive the pushing mechanism and the wedge clamping mechanism to move, so that the three processes of pushing and positioning, centering and clamping, and interface insertion are triggered sequentially along the same feed direction, eliminating the need to set up multiple independent drive units and simplifying the power structure of the device.

[0029] Two support plates 4 are fixedly connected to the upper surface of the testing table 1. A lead screw 5 is rotatably installed between the two support plates 4. A threaded plate 7 is threaded to the outside of the lead screw 5. One of the support plates 4 has a through hole for the connecting rod 8 to pass through. A motor 6 is fixedly installed on the outer surface of the other support plate 4. The output end of the motor 6 is fixedly connected to one end of the lead screw 5. The motor 6 drives the lead screw 5 to rotate, converting the rotational motion into the linear reciprocating motion of the threaded plate 7, providing stable and controllable feed power for the entire device. The support plate 4 not only supports the rotation of the lead screw 5, but also forms a sliding guide for the connecting rod 8 through the through hole in the side wall, ensuring the straightness and smooth operation of the feed process.

[0030] The propulsion mechanism includes a piston cylinder 10 fixedly connected to the outer surface of the moving plate 9. A first spring 11 is fixedly connected inside the piston cylinder 10. A piston rod 12 is fixedly connected to the other end of the first spring 11. The other end of the piston rod 12 slides through the piston cylinder 10 and is fixedly connected to the propulsion plate 13. The piston cylinder 10 and the piston rod 12, together with the first spring 11, form an elastic buffer structure. After the propulsion plate 13 contacts the computer, it can continue to feed. This can push the computer to fit the inner side of the U-shaped frame 2 to complete axial positioning, and also avoid damage to the equipment shell caused by rigid pushing.

[0031] The push plate 13 has a smooth layer on the side near the U-shaped frame 2, and the two clamping plates 16 have anti-slip layers on the sides that are close to each other. The smooth layer can reduce the frictional resistance when the clamping plates 16 push the computer and avoid scratching the computer shell. The anti-slip layer can increase the friction between the clamping plates 16 and the side wall of the computer, improve the stability after clamping, and prevent the computer from shifting position during the test.

[0032] Multiple support strips 3 arranged at equal intervals are fixedly installed on the upper surface of the testing table 1. The support strips 3 are made of flexible material and are laid on the table surface of the testing table 1 to support the bottom of the computer under test. This can reduce the sliding wear between the bottom of the computer and the hard table surface, and can also adapt to the small concave and convex structure of the bottom of the shell through its own deformation, so as to ensure the horizontal stability of the computer after it is placed.

[0033] The bottom surfaces of the two second wedge plates 17 are fixedly connected with sliding columns 18. The other ends of the two sliding columns 18 are slidably connected inside the detection table 1. The sliding columns 18 slide along the preset sliding groove of the detection table 1 to provide radial limit for the opening and closing movement of the second wedge plates 17 and the clamping plate 16, so as to avoid the clamping plate 16 from swaying and misaligning during the wedge extrusion process, and ensure that the clamping plates 16 on both sides move synchronously and center, so as to ensure that the position is centered after the computer clamps.

[0034] The adjustment mechanism includes a first U-shaped plate 19 fixedly connected to one side of the movable plate 9. A first threaded rod 20 is rotatably mounted inside the first U-shaped plate 19. A first knob is fixedly connected to one end of the first threaded rod 20. A first threaded block 21 is threadedly connected to the outer surface of the first threaded rod 20. The first threaded block 21 is slidably connected inside the first U-shaped plate 19. The first U-shaped plate 19 provides stable mounting support for the first threaded rod 20. Rotating the first knob drives the first threaded rod 20 to rotate, which in turn drives the first threaded block 21 to slide directionally along the inner cavity of the first U-shaped plate 19, thereby achieving position adjustment in the first dimension.

[0035] A connecting plate 22 is fixedly connected to the outer surface of the first threaded block 21. The side of the connecting plate 22 away from the first threaded block 21 slides through the moving plate 9 and is fixedly connected to the second U-shaped plate 23. The connecting plate 22 transmits the power of the first threaded block 21 to the second U-shaped plate 23, so that the second U-shaped plate 23 can move synchronously with the first threaded block 21. At the same time, the moving plate 9 is provided with a corresponding through groove to provide sliding clearance space for the connecting plate 22, ensuring that there is no structural interference during the adjustment process.

[0036] A second threaded rod 24 is rotatably mounted inside the second U-shaped plate 23. A second knob is fixedly connected to one end of the second threaded rod 24. A second threaded block 25 is threadedly connected to the outer surface of the second threaded rod 24. The second threaded block 25 is slidably connected inside the second U-shaped plate 23. Rotating the second knob drives the second threaded rod 24 to rotate, which can drive the second threaded block 25 to slide directionally along the inner cavity of the second U-shaped plate 23, completing the second-dimensional position adjustment. In conjunction with the first-dimensional adjustment, the interface point position is adapted in the plane.

[0037] A third U-shaped plate 26 is fixedly connected to the outer surface of the second threaded block 25. A third threaded rod 27 is rotatably installed inside the third U-shaped plate 26. A third knob is fixedly connected to one end of the third threaded rod 27. A third threaded block 28 is threadedly connected to the outer surface of the third threaded rod 27. The third threaded block 28 is slidably connected inside the third U-shaped plate 26. The USB flash drive 29 is fixedly installed on one side of the third threaded block 28. The third U-shaped plate 26 moves synchronously with the second threaded block 25. Rotating the third knob drives the third threaded rod 27 to rotate, which can drive the third threaded block 28 to drive the USB flash drive 29 to complete the third-dimensional position adjustment. The three sets of adjustment structures are independent of each other and do not interfere with each other. The USB flash drive 29 can be adjusted to the precise position of the corresponding interface in the space, adapting to the USB interface of the same specification computer in different positions.

[0038] Working principle

[0039] During the test preparation phase, based on the location of the USB interface of the computer under test, the first, second, and third knobs are rotated respectively. Through the thread transmission of the three sets of threaded rods and corresponding threaded blocks, the spatial coordinates of the USB flash drive 29 are adjusted so that the USB flash drive 29 is precisely aligned with the target interface along the feed direction.

[0040] During the formal test, the computer under test is placed on the support strip 3 of the test table 1 by a robotic arm. The computer is initially located in the area between the two clamping plates 16. Then, the motor 6 is started to rotate forward. The motor 6 drives the lead screw 5 to rotate synchronously. Through the threaded transmission, the threaded plate 7 is fed linearly towards the U-shaped frame 2. The threaded plate 7 drives the moving plate 9, the push plate 13 and the first wedge plate 14 to move forward synchronously through the connecting rod 8.

[0041] During the feeding process, the push plate 13 first contacts the side wall of the computer, pushing the computer to slide along the support strip 3 towards the inside of the U-shaped frame 2 until the other side wall of the computer fits against the inner side wall of the U-shaped frame 2, completing the axial positioning of the computer. The threaded plate 7 continues to feed, and the inclined surface of the first wedge plate 14 contacts the inclined surface of the second wedge plate 17 and generates a lateral squeezing force, pushing the two second wedge plates 17 to move inward synchronously against the tension of the second spring 15, thereby driving the clamping plates 16 on both sides to move towards each other, clamping the computer in the center. At this time, the first wedge plate 14 passes over the inclined section of the second wedge plate 17, and the clamping force remains stable. The moving plate 9 continues to feed, driving the adjustment mechanism and the USB flash drive 29 closer to the computer interface. Finally, the USB flash drive 29 is inserted into the USB interface to complete the insertion action. During this process, the piston cylinder 10 continues to move with the moving plate 9, compressing the first spring 11 inside to form an elastic buffer, avoiding damage to the interface or the USB flash drive 29 by the rigid impact at the moment of insertion.

[0042] After the connection is completed, the supporting testing system executes the preset hot-plug test procedure. After the test is completed, the motor 6 reverses, the lead screw 5 drives the threaded plate 7 to move in the opposite direction, and the USB flash drive 29 is first smoothly pulled out of the interface. Then, the first wedge plate 14 gradually releases the squeezing effect on the second wedge plate 17. The second spring 15 rebounds and drives the clamping plate 16 to move outward to release the computer. The push plate 13 moves backward synchronously with the moving plate 9. All components are reset to the initial state, and the next computer test can be carried out.
