Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Example: An adjustable PCB flexible probe testing device, such as Figures 1-7As shown, the system includes a frame 1, an electric push rod 2, a push frame 3, a mounting plate 4, an adjusting plate 5, a sliding frame 501, a flexible probe module 6, a clamping plate 7, a rotating frame 8, a rotating plate 9, a limiting frame 10, a first connecting plate 11, a sliding rod 12, a limiting plate 13, a spring 14, a second connecting plate 15, a connecting block 16, a third connecting plate 17, a lead screw 18, a guide rod 19, a scale ring 20, a first connecting rod 21, a toggle plate 22, and a second connecting rod 23. An electric push rod 2 is mounted on the frame 1. The telescopic end of the electric push rod 2 is connected to the push frame 3. The bottom of the push frame 3 is connected to the mounting plate 4. Multiple adjusting plates 5 are placed inside the mounting plate 4. Each adjusting plate 5 has a sliding frame 501 symmetrically slidably connected to it. The sliding frame 501 is used to accommodate the flexible probe module. The probe module 6 has a flexible probe module 6 placed inside each sliding frame 501. The flexible probe module 6 can directly contact the test points of the PCB circuit board to complete the electrical performance test. Each sliding frame 501 has a clamping plate 7 symmetrically slidably connected to the left and right sides. The clamping plate 7 can clamp and fix the flexible probe module 6 to prevent it from shifting or falling off during the test and ensure test stability. The mounting plate 4 has rotating frames 8 symmetrically connected to the front and rear sides. Each rotating frame 8 has a rotating plate 9 rotatably connected inside. Each rotating plate 9 has a limit frame 10 connected to it. The limit frame 10 contacts and cooperates with the adjusting plate 5. The mounting plate 4 is connected to a first connecting plate 11. The first connecting plate 11 has sliding rods 12 symmetrically slidably connected to the front and rear sides. The right ends of the two sliding rods 12 are connected to A limiting plate 13 is connected to each of the two limiting plates 13, which are in contact with the corresponding limiting frame 10. The limiting plate 13 can limit and lock the limiting frame 10 to prevent the rotating plate 9 from rotating accidentally during the test. A spring 14 is connected between each of the two limiting plates 13 and the first connecting plate 11. A second connecting plate 15 is connected between the left ends of the two sliding rods 12. A connecting block 16 is connected to the inner side of each sliding frame 501. A third connecting plate 17 is symmetrically connected to each adjusting plate 5. A lead screw 18 is symmetrically connected between the two third connecting plates 17 on each adjusting plate 5. Each connecting block 16 is threadedly engaged with the lead screw 18 at the corresponding position. A guide rod 19 is symmetrically connected between the two third connecting plates 17 on each adjusting plate 5. The guide rod 19 provides linear guidance for the movement of the sliding frame 501. Each connecting block 16 slides with the guide rod 19 at the corresponding position. Multiple scale rings 20 are evenly spaced on each guide rod 19. The scale rings 20 can mark the position scale on the guide rod 19 to help the operator judge the movement distance of the sliding frame 501. Each lead screw 18 is connected to a first connecting rod 21. The first connecting rod 21 is manually rotated by the operator to drive the lead screw 18 to rotate, thereby realizing the movement of the sliding frame 501 and completing the position fine adjustment of the flexible probe module 6. Each first connecting rod 21 passes through the third connecting plate 17 at the corresponding position. Each adjustment plate 5 is symmetrically connected to a toggle plate 22 on the left and right. Each second connecting plate 15 is connected to a second connecting rod 23.
[0024] When testing a PCB circuit board, the operator first pulls the second connecting rod 23 outward. This action moves the second connecting plate 15, the sliding rod 12, and the limiting plate 13 together. At this time, the spring 14 installed between the first connecting plate 11 and the limiting plate 13 is compressed. As the limiting plate 13 moves, its original limiting effect on the limiting frame 10 is released, and the rotating plate 9 can rotate freely. Then, the operator rotates the rotating plates 9 on both sides outward to open them, so that the limiting frame 10 rotates to a suitable angle, thus making room for subsequent operations. After the limiting frame 10 is adjusted into place, the second connecting rod 23 is released, and the spring 14 pushes the sliding rod 12, the limiting plate 13, and the second connecting plate 15 back to their original positions. Next, the operator places a piece of... Adjusting plates 5 are placed in the grooves on mounting plates 4, and the four adjusting plates 5 are installed in sequence. After each adjusting plate 5 is installed, the two clamping plates 7 in the corresponding sliding frames 501 are pushed to the sides to reserve space for the installation of the flexible probe module 6. Then, the flexible probe module 6 adapted to the current PCB model is placed into the sliding frame 501, and the clamping plates 7 are reset to clamp the flexible probe module, which plays a role in fixing and limiting. In order to achieve precise positioning of the flexible probe module 6, the operator rotates the first connecting rod 21 installed on the lead screw 18, which drives the lead screw 18 to rotate. Since each sliding frame 501 is threaded with the lead screw 18 through the connecting block 16 on its inner side and slides with the guide rod 19, the sliding frame 501 can be Driven by the lead screw 18, the slide smoothly along the guide rod 19. During this process, the operator can observe the evenly distributed scale rings 20 on the guide rod 19 to determine the moving position of the sliding frame 501, thereby achieving precise positioning. After adjusting the position of one flexible probe module 6, stop rotating the first connecting rod 21 and perform the same operation on the other side of the first connecting rod 21 to adjust the position of the other flexible probe module 6. After both flexible probe modules 6 are adjusted into place, repeat the above steps to install and position the other three adjusting plates 5 and their corresponding flexible probe modules 6 in sequence. After all the adjusting plates 5 and flexible probe modules 6 are installed and adjusted, pull the second connecting rod 23 again to displace the limiting plate 13, and then rotate the plate 9. The limiting frame 10 returns to its initial position. After the limiting frame 10 resets, the second connecting rod 23 is released, and the spring 14 pushes the limiting plate 13 to reset and re-limit the limiting frame 10, thus completing the overall locking of the multiple adjusting plates 5. At this point, the equipment has completed all preliminary preparations and debugging. Subsequently, the staff places the PCB circuit board to be tested on the frame 1. After confirming that everything is correct, the electric push rod 2 is activated. The telescopic end of the electric push rod 2 drives the push frame 3 and the mounting plate 4 to move downwards, thereby driving multiple flexible probe modules 6 to move downwards synchronously. When the flexible probe module 6 contacts the PCB circuit board, electrical performance testing can begin. After the test is completed, the electric push rod 2 automatically retracts to its initial position, ready for the next test. In subsequent tests...The flexible probe module 6 can be finely adjusted in position by rotating the first connecting rod 21 to adapt to different PCB circuit board models. Simultaneously, it supports quick replacement of the adjustment plate 5 and the corresponding flexible probe module 6 components, giving the equipment good compatibility and flexibility to meet diverse PCB testing needs and facilitate efficient operation by personnel.
