The first pushing cylinder 22 is started to drive the air nozzle 25 to be close to the air valve 200 and communicated with the air valve 200, then high-pressure air is introduced into the detection main body 24 through a high-pressure air source, and the high-pressure air enters the air valve 200 through the air nozzle 25 and is blown out from a through hole of the air valve 200. At this time, the detector can detect whether the size of the through hole of the air outlet valve 200 passes through by detecting the air pressure or the air flow in the inner cavity, and if the air pressure or the air flow is too large, the diameter of the through hole is too small and the through hole does not pass through. On the contrary, the diameter of the through hole is too large and the through hole fails.

After the photographing is finished, if the detection is qualified, the transfer manipulator 5 grabs the air valve 200, meanwhile, the second pushing cylinder 32 drives the first positioning piece 35 to reset, and the transfer manipulator 5 transfers the air valve 200 to the certified product collecting box 43 of the blanking mechanism 4. If the detection is not qualified, the blanking air cylinder 41 drives the waste collecting box 42 to move to a blanking station, so that the transfer manipulator 5 transfers the air valve 200 to the waste collecting box 42 of the blanking mechanism 4.
