The center axis of the roller 72 is radially arranged toward the turntable 21, and the upper end of the roller 72 is against the lower end surface of the turntable 21. During welding, the pressure rod 411 presses the movable seat 32 so that the first spring 212 applies downward pressure to the turntable 21, so that the part of the turntable 21 located at the ultrasonic welding device 4 receives a downward force, which affects the stability of the welding. This can be eliminated by the support of the roller 72, and at the same time, the rotation direction of the roller 72 can match the rotation of the turntable 21.
