The controller 17 is electrically connected to the No. 3 motor 20, and the controller 17 controls the forward and reverse driving of the No. 3 motor 20 according to the sealing of the solenoid valve.

The limiting triangle block 22 is rotated to the position of the guide plate 21 through the limiting triangle block 22. The bottom of the limiting triangle block 22 and the classification box 19 are both on the same horizontal plane. The classification box 19 and the bottom of the limiting triangle block 22 are fixedly installed with a number of There are two storage boxes 23. When the processor 16 analyzes that the solenoid valve is unqualified, it transmits a signal to the controller 17. At this time, the controller 17 controls the No. 3 motor 20 to drive the guide plate 21 to rotate in the forward direction, and then the unqualified solenoid valve on the top of the guide plate 21 slides from the discharge port into the internal storage of the right storage box 23. When the processor 16 analyzes that the solenoid valve is qualified, it transmits a signal to the controller 17.

[0030] The working principle of the above embodiment is:

[0031] When in use, the conveyor belt 2 transfers the solenoid valve to the left side of the support plate 1 in sequence. After the pressure sensor 14 senses that the solenoid valve has fallen to the top of the support plate 13, the conveyor belt 2 stops running. Then the cylinder 6 pushes the rubber pad 7 to approach the fixed clamping plate 4 to clamp the solenoid valve. At this time, the metal tube 8 is just located inside the solenoid valve. Then the air pump 10 runs to generate gas that passes through the soft air pipe 11 and the metal tube 8 into the interior of the solenoid valve. At this time, the CCD industrial camera 15 takes a picture of the pressure gauge 9 and transmits the signal to the processor 16. The processor 16 detects the airtightness of the solenoid valve through the picture analysis of the pressure gauge 9. When the processor 16 analyzes that the solenoid valve is unqualified, it will send the signal The signal is transmitted to the controller 17, at which time the controller 17 controls the No. 3 motor 20 to drive the guide plate 21 to rotate in the forward direction, and then the cylinder 6 retracts to pull the movable clamping plate 5 backward. The No. 2 motor 12 drives the pallet 13 to rotate counterclockwise so that the solenoid valve on the top of the pallet 13 can slide to the top of the guide plate 21, and then the guide plate 21 guides the unqualified ones to the internal storage of the right storage box 23. After the pallet 13 is reset, the conveyor belt 2 continues to convey the solenoid valve to its top for airtightness detection. When the processor 16 analyzes that the detected solenoid valve is qualified, the No. 3 motor 20 drives the guide plate 21 to rotate in the reverse direction to guide the qualified solenoid valve to the internal storage of the left storage box 23.
