A positioning slide 7 is connected, and a relative positioning unit is provided on the positioning slide 7 for positioning the connecting parts; a positioning base 9 is installed on the pressure auxiliary plate 6, and a positioning gear 10 is connected to the positioning base 9; the positioning gear 10 is meshed with the positioning rack 8; a first rubber pad 11 is provided on the side of the pressure auxiliary plate 6 away from the worktable 1; an inflatable energy-absorbing component is provided on the positioning gear 10 to prevent the first rubber pad 11 from collapsing due to long-term use; a displacement T-block 13 is threadedly connected to the displacement screw 5; a displacement L-plate 14 is installed on the displacement T-block 13; a displacement cylinder 15 is fixedly connected to the positioning column 3; the displacement cylinder... Column 15 is connected through to displacement L plate 14, and the two are slidably engaged; displacement slide column 16 is connected through to displacement T block 13 on the side near pressure auxiliary plate 6; displacement slide column 16 and displacement T block 13 are slidably engaged; pressure main plate 17 is installed at the end of displacement slide column 16 near pressure auxiliary plate 6; a second rubber pad 18 is provided on the side of pressure main plate 17 near pressure auxiliary plate 6; signal pieces 19 are provided on the opposite surfaces of pressure main plate 17 and displacement T block 13, and the two signal pieces 19 are electrically connected; a drive motor 20 is installed at the end of positioning column 3 away from worktable 1; the output end of drive motor 20 is rotatably connected to displacement lead screw 5; A displacement spring 21 is fitted onto the displacement slide column 16; one end of the displacement spring 21 is fixedly connected to the pressure main plate 17, and the other end is fixedly connected to the displacement T-block 13; both the second rubber pad 18 and the first rubber pad 11 are provided with air storage cavities 22; the end of the positioning rack 8 away from the worktable 1 is fixedly connected to the displacement T-block 13; the pressure auxiliary plate 6 is provided with a first vent hole 23, and a first valve is installed in the first vent hole 23; the pressure main plate 17 is provided with a second vent hole 24, and a second valve is installed in the second vent hole 24; the second vent hole 24 and the first vent hole 23 are respectively connected to their respective corresponding air storage cavities 22; The connector to be tested, i.e., the product after the main board and flexible circuit board are connected together, is placed on the first rubber pad 11 on the pressure auxiliary plate 6, with both sides of the bottom of the main board in contact with the two first rubber pads 11. By starting the drive motor 20, its output end drives the displacement screw 5 to rotate, which in turn causes the threaded displacement T block 13 to move at the displacement cylinder 15 through the displacement L plate 14. Under the action of the displacement slide 16 and the displacement spring 21, the pressure main board 17 is moved closer to the pressure auxiliary plate 6 until the second rubber pad 18 on the pressure main board 17 contacts the flexible circuit board, so that both the second rubber pad 18 and the first rubber pad 11 are in contact with the bottom of the flexible circuit board and the main board, thus further fixing the flexible circuit board and the main board together. This design avoids the flexible circuit board from being affected by displacement, shaking, or non-human factors during testing. Simultaneously, the second rubber pad 18 and the first rubber pad 11 increase the contact friction between the pressure main board 17 and the pressure auxiliary board 6 when fixing the main board and the flexible circuit board. This prevents the flexible circuit board from dislodging or sliding due to insufficient contact friction when fixing the flexible circuit board and the main board together, thereby further improving the stability of the connector during testing and ensuring and improving the testing accuracy of the flexible circuit board. It is worth mentioning that when the second rubber pad 18 on the pressure main board 17 contacts the flexible circuit board placed on the main board on the first rubber pad 11, by continuing to control the rotation of the displacement screw 5, the displacement T block 13 is positioned... The sliding column 16 moves to a limit position, causing the displacement spring 21 to be in a buffer state. This controls the fixing force of the pressure mainboard 17 on the connector. The smaller the distance between the displacement T-block 13 and the pressure mainboard 17, the more difficult it is to move. Different fixing forces are provided according to the different materials of the mainboard to avoid excessive fixing force on the connector, which could cause damage. This improves the fixing effect on the connector and enhances the connection effect between the mainboard and the flexible circuit board. At the same time, when the displacement T-block 13 moves to a certain distance and its signal piece 19 contacts the signal piece 19 on the pressure mainboard 17, it indicates that the fixing force of the pressure mainboard 17 on the connector has reached its maximum. This prevents further increases that could damage the connector, thus controlling the maximum fixing force on the connector. The second rubber pad 18 and the first rubber pad 11 provide flexible contact for fixing the motherboard and the flexible circuit board, avoiding the impact on the lifespan of the connector caused by rigid contact fixing, thus improving the service life of the flexible circuit board. This allows the motherboard and flexible circuit board to be fixed together in a top-bottom merging manner, while the connector is also fixed at the top and bottom edges of the connector, preventing misalignment or deviation during testing. This improves the testing accuracy of the equipment, avoids interference with test results, and ultimately significantly enhances the practical application effect of equipment fault prediction and health management technology. Furthermore, it eliminates the need for manual fixing of the connector, reducing workload and limitations on equipment use.

[0019] The relative positioning unit in this embodiment includes a positioning rack 8, which is connected through the pressure auxiliary plate 6 on the side away from the worktable 1; the positioning rack 8 and the pressure auxiliary plate 6 are slidably engaged; the end of the positioning rack 8 near the worktable 1 is located inside the positioning slide cylinder 7, and the two are slidably engaged; a T-shaped pipe 25; one input end of the T-shaped pipe 25 is connected to the positioning slide cylinder 7, and the two are connected; the two output ends of the T-shaped pipe 25 are connected to the support base; both output ends of the T-shaped pipe 25 are equipped with U-shaped pipes 26; the two U-shaped pipes 26 are located on both sides of the pressure auxiliary plate 6; the input end of the U-shaped pipe 26 is connected to the output end of the T-shaped pipe 25, and the output end of the U-shaped pipe 26 faces the side of the pressure auxiliary plate 6; a guide slide 27 is connected inside the output end of the U-shaped pipe 26, and the two are slidably engaged; a guide base 28 is installed on the outer wall of the U-shaped pipe 26; a T-shaped pipe 26 is installed at the end of the guide slide 27 away from the U-shaped pipe 26. T-shaped substrate 29; guide spring 30, sleeved on guide slide column 27; one end of guide spring 30 is fixedly connected to T-shaped substrate 29, and the other end is fixedly connected to guide base 28; guide slide groove 31 is provided on the opposite surfaces of the two T-shaped substrates 29; guide slider 32 is slidably connected in the guide slide groove 31; a protective pad 33 is connected to the side of guide slider 32 away from T-shaped substrate 29; when the connector is placed on the first rubber pad 11, the side of the connector is located in the moving path of the protective pad 33; compression spring 34 is provided in the guide slide groove 31; one end of compression spring 34 is fixedly connected to the inner wall of guide slide groove 31, and the other end is fixedly connected to guide slider 32; air outlet U-pipe 35 is connected to both sides of T-shaped substrate 29; air outlet U-pipe 35 is connected to guide slide groove 31; high pressure nozzle 36 is installed on air outlet U-pipe 35; the output end of high pressure nozzle 36 faces the side of connector closer to the second rubber pad 18. During the fixing process of the connector, the displacement T-block 13 moves closer to the worktable 1, causing the positioning rack 8 on the displacement T-block 13 to move downward and be limited within the positioning slide cylinder 7. This allows the gas inside to be sent through the T-shaped pipe 25 into the two U-shaped pipes 26, acting on the guide slide column 27 and limiting its movement within the U-shaped pipe 26. This causes the T-shaped base plates 29 on the two guide slide columns 27 to move relative to each other, causing the guide slider 32 to move closer to the side of the connector under the action of the guide slide groove 31 and the compression spring 34. This allows the two guide sliders 32 to move synchronously relative to each other and contact the two sides of the connector, thus centering and fixing the connector. The fixing position is exactly centered, preventing the locking clamping device from shifting its position when clamping the connector, which would result in poor fixing effect. At the same time, the buffering force provided by the compression spring 34 and the protective pad 33 can also reduce the impact force caused by the shaking of the connector during testing due to non-human factors, further improving the stability of the connector during testing and making the equipment more reliable for the connector testing results. The accuracy of the results is also guaranteed, allowing the locking clamping device to accurately fix the connector, namely the main board and the flexible circuit board, together, avoiding deviations in the fixing position that could interfere with the test results. Simultaneously, when the guide slider 32 contacts the side of the connector, the continued movement of the T-shaped base plate 29 causes the guide slider 32 to move within the guide groove 31, keeping the compression spring 34 in a buffer state to control the positioning strength of the guide slider 32 on the connector. This also compresses the space within the guide groove 31, allowing the gas inside to enter the exhaust U-tube 35 and be ejected by the high-pressure nozzle 36. The ejected gas acts on the side of the connector near the second rubber pad 18, i.e., the flexible circuit board, preventing impurities from being squeezed into the flexible circuit board by the fixing clamping force generated when the locking clamping device fixes the connector, thus preventing damage to the internal circuitry. This improves the fixing effect of the locking clamping device on the connector and extends the service life of the flexible circuit board, thereby enhancing the overall performance of the equipment.

[0020] The inflatable energy-absorbing assembly of this embodiment includes a rotating cam 12 connected to the positioning base 9 on the side away from the positioning gear 10; the positioning gear 10 and the rotating cam 12 are rotatably connected; a limiting base 37 is installed on the positioning base 9; a limiting slide post 38 is provided through the limiting base 37 near the rotating cam 12; the limiting slide post 38 and the limiting base 37 are slidably engaged; a limiting cross block 39 is connected to one end of the limiting slide post 38 near the rotating cam 12, and a braking plate 40 is connected to the other end; the limiting cross block 39 is located at the rotation path of the side wall of the rotating cam 12; a limiting spring 41 is sleeved on the limiting slide post 38; one end of the limiting spring 41 is fixedly connected to the limiting cross block 39, and the other end is fixedly connected to the limiting base 37; an air storage box 42 is installed on the limiting base 37; the braking plate 40 is fitted into the air storage box 42, and the two are slidably engaged; the air storage box 42 is located away from the braking plate 40. A main valve 43 is installed on one side; a vent valve 44 is provided on one side of the gas storage box 42, and a secondary valve 45 is provided on the other side; a bent pipe 46; one end of the bent pipe 46 is connected to the gas storage box 42 and communicates with the main valve 43; the other end of the bent pipe 46 is connected to the pressure auxiliary plate 6 and communicates with the first vent hole 23; a drive square tube 47; one end of the drive square tube 47 is installed on the gas storage box 42 and communicates with the secondary valve 45; the other end of the drive square tube 47 faces the pressure main plate 17; a corrugated square tube 48; one end of the corrugated square tube 48 is installed on the pressure main plate 17 and communicates with the second vent hole 24; the other end of the corrugated square tube 48 faces the worktable 1; the end of the drive square tube 47 facing the pressure main plate 17 is on the moving path of the corrugated square tube 48 facing the end of the worktable 1; when the connector placed on the first rubber pad 11 contacts the second rubber pad 18, the drive square tube 47 and the corrugated square tube 48 are connected. When the positioning rack 8 moves downward, it meshes with the positioning gear 10, causing it to rotate and drive the rotating cam 12 to rotate. This causes the cam 12 to continuously contact the limiting block 39, which then moves back and forth at the limiting base 37 via the limiting slide pin 38. This keeps the limiting spring 41 in a buffered and reset state, allowing the brake square plate 40 to move back and forth within the air storage box 42. This controls the opening and closing of the vent valve 44, the secondary valve 45, and the main valve 43. The vent valve 44 is the main source of air intake, causing the bent pipe 46 and the drive square pipe 47 to continuously generate... Gas, some of which is sent into the first vent 23 through the bent pipe 46 and into the first rubber pad 11 on the pressure auxiliary plate 6, causing it to expand; when the locking clamping device fixes the main board to the flexible circuit board, the driving square tube 47 and the corrugated square tube 48 are connected, so that the gas generated by the driving square tube 47 is sent into the second vent 24 through the corrugated square tube 48, causing the second rubber pad 18 on the pressure main board 17 to expand, preventing the second rubber pad 18 and the first rubber pad 11 from being fixedly connected. When components are used for too long, their elasticity may deteriorate or they may collapse, reducing their effectiveness in securing the motherboard and flexible circuit board. Therefore, the locking clamping device ensures that the second rubber pad 18 and the first rubber pad 11 are always fully inflated when securing the connector. The cushioning effect provided by the gas within the second rubber pad 18 and the first rubber pad 11 also reduces the impact force on the connector during fixation, improving the stability of the connection between the motherboard and the flexible circuit board. This ensures that the second rubber pad 18 and the first rubber pad 11 maintain flexible contact with the connector at all times, preventing connector misalignment or displacement from affecting the test results. This improves and ensures the accuracy and precision of the equipment tests, extends the service life of the second rubber pad 18 and the first rubber pad 11, reduces the "damaging stress" experienced during use, slows down material aging and structural damage, avoids the need for frequent maintenance, reduces the limitations of equipment use, and simultaneously improves the equipment's effectiveness in securing the connector.
