[0017] 1. When the present invention is in use, the position of the positioning rod can be adjusted according to the model of the board to be tested so that it can be aligned with the fixing hole on the board to be tested. When adjusting the position of the positioning rod, it is only necessary to grasp the positioning rod, pull the insertion rod out of the slot, then pass the insertion rod through the through hole through the silicone pad, and insert it into the slot corresponding to the position of the fixing hole on the board to be tested. When the insertion rod is inserted again, the insertion rod can squeeze the clamping ring. When the insertion rod is fully inserted into the slot, the clamping ring is flush with the clamping slot. At this time, the clamping ring rebounds under the action of its own elasticity, and can be clamped into the clamping slot to limit the insertion rod, thereby fixing the insertion rod in the slot, and then aligning the fixing hole on the board to be tested with the positioning rod and placing it in the placement slot, the positioning rod can limit the position of the board to be tested, and the silicone pad can avoid excessive force when fixing the board to be tested and causing pressure loss. In summary, when in use, the position of the positioning rod can be adjusted according to the model of the board to be tested, so as to position boards of different models to be tested and avoid them from being subjected to pressure loss.

[0018] 2. Before placing the board to be tested, the present invention replaces the limit plate according to the model of the board to be tested, so that the positioning hole on the limit plate is consistent with the position of the positioning rod. When replacing the limit plate, first slide the dial block in the dial slot to pull the fixing card out of the installation slot, release the restriction on the installation bar, and then the limit plate can be pulled out from the base plate, and then the new limit plate can be installed in the base plate. When installing the limit plate, align the installation bar with the installation slot and insert it. The installation bar can be pressed into the fixing slot through the inclined surface of the fixing card, and the fixing spring is compressed. When the limit plate is fully inserted into the base plate, the fixing card is It can rebound into the installation groove under the action of the fixing spring to limit the installation bar, thereby fixing the limit plate. When placing the board to be tested, first lift the base plate on the support rod through the sliding hole to facilitate the placement of the board to be tested. After the placement is completed, release the base plate, and the base plate can automatically slide down under the action of gravity, and make the positioning rod pass through the positioning hole, so that the limit plate limits the board to be tested and the detection position of the board to be tested is exposed, which is convenient for its detection. In summary, when in use, the limit plate can be easily replaced to fix different types of boards to be tested.

[0019] 3. During detection, the present invention first closes the electromagnetic valve in the corresponding sleeve according to the detection position on the board to be tested, and then the lifting rod drives the detection board to descend. The airbag is stretched as the detection board descends, and the air in the sleeve above the non-detection area can be drawn into the airbag through the air cavity and the electromagnetic valve, thereby sucking the probe into the sleeve through negative pressure to avoid the probe from contacting the non-detection area of ​​the board to be tested. Since the electromagnetic valve of the sleeve above the detection area is closed, the probe will remain protruding outside the sleeve, and will contact the board to be tested as the detection board descends, thereby detecting it. When the probe contacts the board to be tested, as the probe is subjected to force, it can slide in the sleeve and compress the reset spring, so that the reset spring buffers the force applied to the probe, thereby avoiding the probe from being subjected to force. The pressure is too high and the probe is damaged. After the detection is completed, the solenoid valves are fully opened, and the lifting rod drives the detection plate to rise. The probe can be reset under the action of air pressure and reset spring. After the detection plate rises to its initial position, it continues to rise. The airbag is squeezed and the gas can be squeezed into the sleeve from the solenoid valve through the air cavity, so that the probe moves and the nozzle is opened. The air can leave the sleeve from the nozzle and form a fast airflow to blow the probe head, thereby cleaning the probe head. After cleaning, the lifting rod drives the detection plate to return to its initial position, which is convenient for the next detection. In summary, when using, the probe can be adjusted according to the model of the board to be tested, and the force on the probe can be buffered during detection to avoid damage to the probe, and the probe head can be cleaned after the detection is completed.

Since the electromagnetic valve 605 of the sleeve 602 above the detection area is closed, the probe 608 will remain protruding from the outside of the sleeve 602, and contact the board to be tested as the detection plate 601 descends.Thus, the probe 608 can be inspected, and when the probe 608 contacts the board to be tested, as the probe 608 is stressed, it can slide in the sleeve 602 and compress the reset spring 607, so that the reset spring 607 buffers the stress on the probe 608, and prevents the probe 608 from being damaged due to excessive pressure.
