[0029] In another embodiment, Figure 1-Figure 8As shown, a fixed plate 4 is fixedly installed on the top of the placement plate 2, an electromagnetic plate 37 is fixedly installed inside one side of the fixed plate 4, an adjusting slot 7 is opened on the top of the detection seat 1, an adjusting slider 43 is slidably installed inside the adjusting slot 7, a movable clamping plate 3 is fixedly installed on the top of the adjusting slider 43, a movable magnetic plate is fixedly installed inside one side of the movable clamping plate 3, and the magnetic poles of the movable magnetic plate and the electromagnetic plate 37 opposite to each other are the same, an inner sleeve sliding column 36 is fixedly installed inside the adjusting slot 7, and the adjusting slider 43 is slidably installed on the outside of the inner sleeve sliding column 36, and the inner A spring 27 is installed on the outer side of the sleeve sliding column 36, one end of the spring 27 is fixedly connected to one side of the inner cavity of the adjusting slide groove 7, and the other end of the spring 27 is fixedly connected to one side of the adjusting slider 43, two placement blocks 8 are symmetrically fixedly installed on the top of the placement plate 2, a rubber pad 31 is fixedly installed on the side of the movable clamping plate 3 away from the movable magnetic plate, a power connection bar 34 is fixedly installed on one side of the rectangular groove 17, and a power connection plate 25 is fixedly installed on the side of the fixed plate 4 away from the electromagnetic plate 37, and the position of the power connection plate 25 corresponds to the position of the power connection bar 34.

[0030] When the placement plate 2 moves with the integrated circuit board, the power connection piece 25 on one side of the fixed plate 4 will contact the power connection bar 34, thereby supplying power to the electromagnetic plate 37, so that the electromagnetic plate 37 has magnetic force, thereby generating a repulsive force on the moving magnetic plate on one side of the moving clamping plate 3, thereby pushing the moving clamping plate 3 to move, clamping and fixing the integrated circuit board placed on the top of the placement block 8, ensuring that the integrated circuit board remains in a fixed state and does not move when the vibration detection of the integrated circuit board is performed, thereby ensuring the accuracy of the vibration detection of the integrated circuit board, and in addition, by adopting the clamping driven by the repulsive force, the damage to the integrated circuit board caused by the clamping can be avoided. In addition, when the placement plate 2 moves to the two ends of the detection seat 1, the power connection piece 25 will be separated from the power connection bar 34, and the electromagnetic plate 37 loses its magnetic force. Under the elastic force of the inner sleeve slide column 36 to restore its deformation, the adjusting slider 43 can be pushed to move inside the adjusting slide groove 7, thereby stopping the clamping of the integrated circuit board, making it convenient to take and place the integrated circuit board.

[0031] In another embodiment, Figure 1-Figure 8As shown, the interior of the fixed plate 4 is symmetrically provided with two rectangular sleeve grooves 38, and the interiors of the two rectangular sleeve grooves 38 are slidably installed with a fixed pull rod 26 and a vibrating stop rod 24, respectively.

A spring pressure plate 39 is fixedly installed, and a spring 40 is fixedly connected to one side of the spring pressure plate 39. A movable push plate 41 is fixedly installed on one end of the vibration resisting rod 24 away from the vibration push rod 29, and a plurality of vibration striking blocks 42 are fixedly installed on one side of the movable push plate 41.

[0032] When the movable splint 3 moves, the movable plate 23 can be pulled to move inside the movable groove 33 by the fixed pull rod 26, and the placement plate 2 can drive the movable splint 3 to move when it moves, so that the fixed pull rod 26 can move on the outside of the movable plate 23, and drive the vibration push rod 24 to move, thereby driving the vibration push rod 29 to move on the surface of the movable plate 23. When the vibration push rod 29 moves to the position of the vibration protrusion 230, the vibration protrusion 230 can press the vibration push rod 29, and cooperate with the spring 240 and the spring pressure plate 239 to make the vibration push rod 24 reciprocate, so that the movable push plate 41 reciprocates inside the storage groove 44, so that the vibration striking block 42 continuously moves back and forth to knock and vibrate the integrated circuit board, which can effectively transmit energy to every corner and tiny structure of the integrated circuit board, so that potential defects or poor connections inside it can be fully revealed, and vibration detection can be performed from the side to improve the accuracy of detection.

[0033] Working principle: First, an external power supply is connected to place the integrated circuit board on the top of the placement board 2, and the integrated circuit board is connected to the external detection equipment. Then, according to the position of the integrated circuit board, the position of the adjustment tube 11 inside the mounting frame 12 is adjusted to make the position between the vibration head 13 and the integrated circuit board five millimeters, and the sliding sleeve 18 is moved downward to make the bottom of the vibration plate 16 and the top of the vibration push rod 9 on the same horizontal plane, and then the drive motor 19 is started. The output end of the drive motor 19 can drive the threaded rod 6 to rotate, so that the moving slider 28 moves inside the moving slide groove 5. When the placement board 2 moves, it can drive the integrated circuit board to move, and when the vibration push rod 9 passes the bottom of the vibration plate 16, the vibration plate 1 The vibration protrusion 20 at the bottom of 6 will continuously push the vibration push rod 9, and cooperate with the spring pressure plate 3 46 and the spring 3 45, so that the vibration slide column 10 can continuously move up and down inside the adjustment tube 11, thereby driving the vibration head 13 to continuously move up and down, and continuously knocking the integrated circuit board, so that the integrated circuit board vibrates, and observes the external detection equipment to determine whether the integrated circuit board is damaged, which can realize comprehensive and accurate vibration detection of the integrated circuit board.

When the placement board 2 carries the integrated circuit board to move, the power connection sheet 25 on one side of the fixed board 4 will contact the power connection bar 34, thereby supplying power to the electromagnetic board 37, so that the electromagnetic board 37 has magnetic force, thereby generating a repulsive force on the moving magnetic plate on one side of the moving clamping plate 3, thereby pushing the moving clamping plate 3 to move, clamping and fixing the integrated circuit board placed on the top of the placement block 8, ensuring that the integrated circuit board remains fixed when the vibration detection is performed on the integrated circuit board, and will not move, thereby ensuring the accuracy of the vibration detection of the integrated circuit board. In addition, by adopting the clamping driven by the repulsive force, the damage to the integrated circuit board caused by the clamping can be avoided. In addition, when the placement board 2 moves to both ends of the detection seat 1 , the power connection sheet 25 will be separated from the power connection bar 34, the electromagnetic plate 37 loses its magnetic force, and the inner sleeve slide column 36 can push the adjustment slider 43 to move inside the adjustment slide groove 7 under the elastic force of restoring the deformation, thereby stopping the clamping of the integrated circuit board, making it convenient to take and place the integrated circuit board, and when the movable clamping plate 3 moves, the movable plate 23 can be pulled to move inside the movable groove 33 by the fixed pull rod 26, and the placement plate 2 can drive the movable clamping plate 3 to move when it moves, so that the fixed pull rod 26 can move on the outside of the movable plate 23, and drive the vibration push rod 24 to move, thereby driving the vibration push rod 29 to move on the surface of the movable plate 23, when the vibration push rod 29 moves to the position of the vibration protrusion 2 30,The vibration protrusion 2 30 can press the vibration push rod 29, and cooperate with the spring 2 40 and the spring pressure plate 2 39 to make the vibration push rod 24 reciprocate, so that the moving push plate 41 reciprocates inside the storage groove 44, so that the vibration striking block 42 continuously reciprocates to knock and vibrate the integrated circuit board, which can effectively transmit energy to every corner and tiny structure of the integrated circuit board, so that the potential defects or poor connection problems inside the integrated circuit board can be fully revealed, and vibration detection can be performed from the side to improve the accuracy of detection.
