[0062] Working principle:

[0063] 1), The vibrating disk 41 vibrates to vibrate the plug to the feeding track 42, and then the plug is conveyed to the position of the clamping mechanism through the feeding track 42. Then, the clamping cylinder 50 of the clamping mechanism controls the clamping claws 51 to grab the plug and place it on the plurality of plug fixing seats 31 of the transfer turntable 3;

[0064] 2), The air inlet pipe at the lower end of the O-ring storage tank 52 introduces compressed air into the O-ring storage tank 52 to blow up the O-rings in the O-ring storage tank 52, and conveys them to the blanking seat 56 through the material channel 53. Then, the O-rings fall through the blanking holes 57 onto the guide rod 61; when passing through the conical blanking portion 63 of the guide rod 61, at the same time, the plug fixing seat 31 on the transfer turntable 3 just rotates to directly below the guide rod 61;

[0065] 3), The pusher claws 64 of the pusher mechanism push the O-rings on the cylindrical blanking portion 62 of the guide rod 61 to the conical blanking portion 63, so as to expand the O-rings through the conical blanking portion 63. At the same time, the ejector cylinder 36 controls the ejector rod 33 to eject the plug fixing seat 31 upward, so that the plug is just located at the lower end of the guide rod 61. Thus, the pusher claws 64 push the O-rings on the conical blanking portion 63 onto the plugs, realizing the automatic assembly of the O-rings and the plugs.
