At the same time, if there is a welded part in the mold box 6 corresponding to the top block 14, When the welding is completed, the welded parts will be ejected by the ejector block 14 during the descent of the turntable 5 to realize blanking. After 5 seconds, the welding head 11 returns, and the driving end of the cylinder 9 pushes the turntable 5 upward. The turntable 5 will drive the corresponding mold box 6 away from the ejector block 14 and the button 16. The circuit of the welding head 11 is disconnected, and the motor 2 drives the turntable 5 to rotate again. This cycle is repeated to complete the ultrasonic welding and ejection of the welded parts in turn. The worker only needs to put the waterproof button to be welded, that is, the connector, into the mold box 6, which greatly reduces the labor intensity of the workers and improves the processing efficiency.
