The operation of the automatic full inspection machine 100 for gas valves according to the present invention will be described in detail with reference to the accompanying drawings:

the feeding mechanism 7 sequentially conveys the air valves 200 to the positioning mechanism 6 through the conveying groove, the positioning cylinder 61 is started and pushes the positioning block 63 to slide on the positioning seat 62, at this time, the positioning block 63 opens the positioning groove 621, so that the positioning groove 621 corresponds to the outlet of the conveying groove, and the air valves 200 enter the positioning groove 621 from the conveying groove. Then the positioning cylinder 61 resets and drives the positioning block 63 to reset so as to clamp and position the air valve 200. At this time, the motor 52 is activated to drive the driving rod 53 to swing, thereby driving the arm 54 to move.

Then, the arm 54 driven by the motor 52 in the reverse direction moves, so that the holding jaw 55 located above the positioning mechanism 6 moves above the valve checking mechanism 2 and the valve 200 is placed on the valve checking mechanism 2.

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 air valve detection mechanism 2 finishes detection, the first pushing cylinder 22 resets and drives the air tap 25 to leave the air valve 200; at this time, the transfer robot 5 takes out the gas valve 200 of the gas valve detection mechanism 2 and transfers the gas valve to the CCD detection mechanism 3. The third pushing cylinder 36 is started to drive the second positioning block 63 to extend out, then the second pushing cylinder 32 is started to drive the first positioning block 63 to extend out, and further the air valve 200 is clamped together with the second positioning block 63, and at this time, the first positioning block 63 is inserted into the inner cavity of the air valve 200. Then, the third pushing cylinder 36 drives the second positioning block 63 to reset, so that the air valve 200 is only horizontally sleeved on the first positioning block 63. At this time, the CCD camera 31 can take a picture for detection.

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.

In the process of transferring the gas valve 200 by the transfer robot 5, the transfer robot 5 has three clamping jaws 55 corresponding to three stations at the same time. Therefore, when one clamping jaw 55 of the transferring manipulator 5 grabs the air valve 200 on the positioning mechanism 6, the other two clamping jaws 55 can respectively and simultaneously transfer the air valve 200 detected on the air valve detection mechanism 2 and the air valve 200 detected on the CCD detection mechanism 3, transfer the air valve 200 detected on the air valve detection mechanism 2 to the CCD detection mechanism 3, and transfer the air valve 200 detected on the CCD detection mechanism 3 to the blanking mechanism 4, thereby improving the production efficiency.

Compared with the prior art, because the utility model discloses a set up an air valve detection mechanism 2 and detect the through-hole size of air valve 200, set up a CCD detection mechanism 3 again and detect the size of a dimension of air valve 200, recycle unloading mechanism 4 and screen classification to the air valve 200 after detecting, each station is operated through a transfer manipulator 5, get the air valve 200 on each station simultaneously and put and transfer simultaneously through a plurality of clamping jaws 55 on the transfer manipulator 5, thereby realize the synchronization of each station; the whole process is operated in a full-automatic mode, manual operation is not needed, the labor intensity is effectively reduced, and the production efficiency is improved.
