s2, opening a sucker assembly (25) through a control seat (17), sucking the bottom of the sleeve (33) by a sucker (251), enabling the bottom end of the sleeve (33) to be stable and motionless, and then moving the semicircular ring (21) and the elastic ring (22) inwards through a hydraulic drive II (18), so that the sleeve (33) is clamped by the elastic ring (22);
s3, adjusting the height of the double-layer clamp (32) through the height required to be clamped by the sleeve (33), pushing the clamping block (322) inwards through the control switch (324) after the adjustment is completed, enabling the clamping block (322) to clamp the sleeve (33) in a positioning manner, and finally welding the top of the sleeve (33);
s4, after welding is completed, the ultrasonic assembly (253) is started through the control seat (17), the ultrasonic assembly (253) generates vibration, the sleeve (33) is vibrated through the air bag tube (255), and the coating welded on the top of the sleeve (33) falls downwards.
