[0034] Working principle: The rotary motor 10 drives the turntable 32 to rotate. The upper surface of the turntable 32 is equipped with a circumferential array of fixtures 39. After the mechanism of each station completes its action, the rotary motor 10 drives the turntable 32 to rotate to the next station. First, the baffle plate is fed by the baffle plate feeding vibratory plate 14 and reaches the loading position through the baffle plate loading track 13. The loading position is equipped with a sensor to detect the small protrusions of the baffle plate to distinguish between the front and back. The baffle plate loading robot 11 moves into place, and the vacuum nozzle 12 on it picks up the baffle plate. If the baffle plate is reversed, another rotary motor 10 on the baffle plate loading robot 11 drives the vacuum nozzle 12 to rotate 180 degrees and then places the baffle plate on the fixture 39 of the turntable 32.

[0035] Turntable 32 rotates to the next station. The nipple is fed through nipple feeding vibratory plate 24 and reaches the feeding position through nipple feeding track 25. There is a cover plate 15 above the nipple feeding track 25 to stabilize the nipple. In the nipple pressing mechanism 38, cylinder 18 drives the nipple pressing rod 20 to press down and insert the nipple into the baffle plate of fixture 39. Guide shafts 19 are slidably fitted on both sides of the nipple pressing rod 20. Below it is a nipple pressing stabilizing plate 22. Fixed cylinder 21 drives the nipple pressing rod 20 to press against the nipple pressing stabilizing plate 22. Another cylinder 18 and fixed plate 23 press the nipple to prevent the nipple from being lifted when the nipple pressing rod 20 returns. The rod is released when it completes its return.

[0036] Turntable 32 rotates to the next station. The pull ring is fed by the pull ring feeding vibratory plate 26, passes through the pull ring feeding track 30 to the tail end, and is distributed to the feeding position by the distributing cylinder 9. It enters the pull ring feeding mechanism 34. The pull ring gripper cylinder 28 drives the pull ring feeding robot 27. The nipple clamp lifting motor 4 in the pull ring feeding robot 27 drives the belt 5. The belt 5 drives the slider on the slide rail 3, so that the nipple clamp cylinder 7 drives the pull ring gripper 29 to clamp the pull ring. The pull ring feeding robot 27 then enters the pull ring assembly mechanism 33 and places the pull ring on the fixture 39.

[0037] Turntable 32 rotates to the next station. The nipple clamp cylinder 7 drives the nipple clamp 6 to clamp the nipple below and lift it upwards. The side support cylinder 1 drives the side support mechanism 2 to insert and support the lower edge of the nipple tail. Then, turntable 32 rotates to the next station. The cap is fed through the cap feeding vibratory plate 17, passes through the cap feeding track 8 to the tail end, and is distributed to the feeding position by the distributing cylinder 9. The vacuum nozzle 12 on the cap feeding robot 16 picks up the cap and presses it onto the fixture 39. Then, turntable 3... 2. The rotation causes the fixture 39 to reach the ultrasonic welding machine 31 for ultrasonic welding. After welding, the turntable 32 rotates to the discharge station, and the discharge robot 35 discharges the finished product and places it into the good product discharge pipe 36 and the defective product discharge pipe 37 respectively. Through the coordinated operation of the turntable 32 and the functional mechanisms of each station, this utility model realizes fully automatic feeding, assembly, welding and sorting from wind deflectors, nipples, pull rings to lids, solving the problems of low assembly efficiency and low degree of automation in the prior art.
