Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1. Please refer to Figures 1 - 5 , the present invention provides a technical solution: a computer-based PCB hardware testing device, including a support table 1.

[0033] A clamping mechanism 5 is arranged on the surface of the bottom plate 2. The clamping mechanism 5 includes a clamping mechanism 52 and a locking mechanism 53;

[0034] A support mechanism 51 is arranged on the surface of the bottom plate 2. The support mechanism 51 includes a limit sleeve 511. The bottom of the limit sleeve 511 is fixedly connected to the surface of the bottom plate 2. A sliding groove 3 513 is provided on the outer wall of the limit sleeve 511. The inner wall of the limit sleeve 511 is slidably connected to the outer wall of the driving rod 512. The bottom of the driving rod 512 penetrates the surface of the bottom plate 2 and is fixedly connected to the output end of the cylinder 7. The inner wall of the driving rod 512 is slidably connected to the outer wall of the guide rod 514. The inner wall of the driving rod 512 is slidably connected to the outer wall of the limit rod 1 516;

[0035] A shock absorption assembly 517 is arranged on the top of the guide rod 514. The shock absorption assembly 517 includes a support head 5171. The bottom of the support head 5171 is fixedly connected to the top of the guide rod 514. A spring 1 515 is arranged at the bottom of the support head 5171. One end of the spring 1 515 is fixedly connected to the bottom of the support head 5171, and the other end is fixedly connected to the inner wall of the driving rod 512. The inner wall of the support head 5171 is slidably connected to the outer wall of the shock absorption block 5172. The outer wall of the shock absorption block 5172 is fixedly connected to the outer wall of the connecting plate 5173. A spring 2 5174 is arranged at the bottom of the connecting plate 5173. One end of the spring 2 5174 is fixedly connected to the bottom of the connecting plate 5173, and the other end is fixedly connected to the inner wall of the support head 5171. The outer wall of the support head 5171 is fixedly connected to the inner wall of the platform 6. A sliding groove 2 9 is provided on the surface of the platform 6. The shock absorption block 5172 protrudes from the surface of the support head 5171 by pressing the connecting plate 5173 through the spring 2 5174, so that the pressure generated when the device detects the PCB is buffered. At the same time, the material of the shock absorption block 5172 is rubber material, which can effectively support the PCB and prevent the static electricity on the surface of the platform 6 from damaging the PCB;

[0036] There are four sets of the first limiting rods 516. The four sets of the first limiting rods 516 are equidistantly arrayed on the inner wall of the driving rod 512 with the center line of the driving rod 512 as the rotation axis. The number of the clamping mechanisms 52 and the locking mechanisms 53 is four sets each. The four sets of the clamping mechanisms 52 and the locking mechanisms 53 are equidistantly arrayed on the outer wall of the driving rod 512 with the driving rod 512 as the rotation axis.

[0037] The working principle of this embodiment is as follows: When the PCB hardware testing device based on a computer is put into use, place the PCB board on the surface of the platform 6, start the air cylinder 7 to drive the driving rod 512 to descend. Through the sliding of the driving rod 512 on the inner wall of the third sliding groove 513, drive the first limiting rod 516 and the supporting head 5171 to descend. At the same time, the driving rod 512 drives the locking mechanism 53 and the clamping mechanism 52 to clamp the PCB, and start the test after the PCB is fixed. During the test, the pressure generated on the PCB drives the supporting head 5171 and the platform 6 to compress the first spring 515, so that the guiding rod 514 and the first limiting rod 516 slide on the inner wall of the driving rod 512 to drive the supporting head 5171 and the platform 6 to descend. When the PCB generates a bending deformation, the shock-absorbing block 5172 squeezes the second spring 5174 through the connecting plate 5173 and slides on the inner wall of the supporting head 5171, providing shock absorption and support for the PCB. After the detection is completed, start the air cylinder 7 to drive the driving rod 512 to reset, and the locking mechanism 53 drives the clamping mechanism 52 to reset and release the clamping of the PCB, and then remove the PCB and wait for the next processing.

[0038] Embodiment 2, please refer to Figures 6 - 7 , the technical solution provided by the present invention is: The clamping mechanism 52 includes a first connecting sleeve 521.

The outer wall of the first hinge rod 522 away from the first connecting sleeve 521 is slidably connected to the inner wall of the first sliding sleeve 523;

[0039] The inner wall of the first sliding sleeve 523 away from the first hinge rod 522 is slidably connected to the outer wall of the second hinge rod 524. A third spring 525 is arranged on the inner wall of the first sliding sleeve 523. One end of the third spring 525 is fixedly connected to the outer wall of the first hinge rod 522, and the other end is fixedly connected to the outer wall of the second hinge rod 524. A jaw assembly 526 is arranged on the side of the second hinge rod 524 away from the first sliding sleeve 523;

[0040] The jaw assembly 526 includes a second sliding sleeve 5261. The bottom of the second sliding sleeve 5261 is hinge-connected to one end of the second articulated rod 524 away from the first sliding sleeve 523 through a hinge block.

A fourth spring 5267 is arranged on the inner wall of the adjustment block 5263. Both ends of the fourth spring 5267 are fixedly connected to the outer wall of the locking block 5266. The locking block 5266 protrudes from the outer wall of the adjustment block 5263 by the spring extrusion and is clamped with the wall of the adjustment groove 5262, so that during the process of the fixed block 5264 clamping the PCB, the adjustment block 5263 slides on the inner wall of the adjustment groove 5262 for adjustment, preventing the fixed block 5264 from applying excessive clamping force to the PCB and causing damage to the PCB.

[0042] The working principle of this embodiment is as follows: The cylinder 7 drives the driving rod 512 to descend, and the locking mechanism 53 supports the first sliding sleeve 523, so that the first articulated rod 522 and the second articulated rod 524 compress the fourth spring 5267 and slide on the inner wall of the first sliding sleeve 523. At the same time, the first articulated rod 522 is hinge-connected to the outer wall of the first connecting sleeve 521, and the second articulated rod 524 is hinge-connected to the bottom of the second sliding sleeve 5261. The locking mechanism 53 supports and drives the second sliding sleeve 5261 to slide on the wall of the first sliding groove 8, driving the fixed block 5264 and the cushion block 5265 to contact and clamp the PCB. By continuously supporting the first sliding sleeve 523 by the locking mechanism 53, the adjustment block 5263 slides on the inner wall of the adjustment groove 5262, and the locking block 5266 is clamped and locked with the adjustment groove 5262 by the extrusion of the fourth spring 5267, so that the fixed block 5264 clamps and fixes the PCB.

[0043] Embodiment 3, based on Embodiment 2, please refer to Figure 8, the present invention provides a technical solution: The locking mechanism 53 includes a third articulated rod 531.

The outer wall of the limiting block 534 is slidably connected to the wall of the first sliding groove 8;

[0044] The inner wall of the second connecting sleeve 532 is slidably connected to the outer wall of the support rod 535. The top of the outer wall of the support rod 535 is hinged to the outer wall of the first sliding sleeve 523 through a rotating shaft. A fifth spring 536 is arranged on the outer wall of the support rod 535. One end of the fifth spring 536 is fixedly connected to the outer wall of the support rod 535, and the other end is fixedly connected to the outer wall of the second connecting sleeve 532.

[0045] The working principle of this embodiment is as follows: The cylinder 7 drives the driving rod 512 to descend. The third articulated rod 531 is hinged to the driving rod 512, so that one end of the third articulated rod 531 close to the driving rod 512 descends. The third articulated rod 531 is hinged to the bottom of the second connecting sleeve 532, and drives the limiting block 534 to slide on the wall of the first sliding groove 8 through the second limiting rod 533, so that the second connecting sleeve 532 drives the support rod 535 to move towards the driving rod 512 and support the first sliding sleeve 523. During the movement of the support rod 535, the inclination of the first sliding sleeve 523 drives the support rod 535 to compress the fifth spring 536 and slide upward on the inner wall of the second connecting sleeve 532, ensuring that the clamping mechanism 52 supports and clamps the PCB.
