[0108] Working principle and control process:

[0109] Press the CNC start button, the equipment is powered on, and the working light is on. The pressure sensor 38 on the gas supply tank 5 detects the gas supply tank 5 in real time. When the pressure is lower than the set lower limit, the intake electromagnetic cut-off valve on the intake side pipeline of the gas supply tank 5 opens. When the pressure reaches the set upper limit, the intake electromagnetic cut-off valve closes. In this way, the pressure of the gas supply tank 5 can be maintained within the set range to ensure the stable operation of the equipment.

[0110] The inspection platform in the present utility model has two airtight detection components 3, that is, it has two airtight detection stations. The following takes the first station as an example for specific description:

[0111] Place the assembled hydraulic oil filter 4 in the first station, click the start button on the touch screen 101 (or press the "Station 1 Start" button on the front side of the workbench). The electromagnetic directional valve 334 operates, and the two clamping cylinders 333 act, and the jaws fix the hydraulic oil filter 4. After a 2-second delay, another electromagnetic directional valve 334 operates, and the pressing cylinder 342 acts. The guide post and the pressing post pull the jaws downward tightly; after a 2-second delay, the sealing cylinder 391 acts to press the oil port (the horizontal port) of the hydraulic oil filter 4 to maintain a seal. After a 2-second delay, the first electromagnetic shut-off valve 35 and the second electromagnetic shut-off valve 36 are energized. When the air pressure reaches the upper limit of the pressure sensor 38 on the test tank 31, the first electromagnetic shut-off valve 35 is de-energized. After reaching the set balance time, the second electromagnetic shut-off valve 36 closes, and the differential pressure transmitter 37 operates according to the set time. After reaching the set time, the air release electromagnetic shut-off valve 6 is energized. When the pressure is relieved to 10 KPa, another electromagnetic directional valve 334 (the electromagnetic directional valve connected to the pressing cylinder and the sealing cylinder) is de-energized; after a 2-second delay, the electromagnetic directional valve 334 connected to the two clamping cylinders is de-energized. At this time, the cylinders are all reset, and the tested hydraulic oil filter 4 can be taken out. If the detected differential pressure does not fall below the set differential pressure value within the set time, it is judged to be qualified. If it is lower than the differential pressure set value, "air leakage, unqualified" is displayed on the system panel, and at the same time the buzzer sounds, and the product is automatically counted as the unqualified quantity. Click the "Reset" button on the screen, and the system resets, and the buzzer stops working.

[0112] The operation of the second station is exactly the same as that of the first station, so it will not be elaborated too much.

[0113] In addition, it should be noted that during the test, if it is necessary to terminate the test, you can click the "Stop" button on the screen (or press the corresponding "Station 1 Stop" or "Station 2 Stop" button on the front side of the workbench), and the system will immediately stop the test. At this time, the electromagnetic shut-off valve will open for exhaust and the cylinder will reset in accordance with the set program. If the "Emergency Stop" button is pressed, the solenoid valves at all stations will be immediately de-energized to ensure safety. After troubleshooting or eliminating potential safety hazards, reset the "Emergency Stop" button.

[0114] Here, it should be noted first that "inward" is the direction towards the center of the accommodation space, and "outward" is the direction away from the center of the accommodation space.
