[0024] The ultrasonic coating bubble breaking device, such as Fig. 1-5As shown, the system includes a support platform 1 and an ultrasonic bubble-breaking unit, with at least one ultrasonic bubble-breaking unit mounted on the support platform 1. Each ultrasonic bubble-breaking unit includes an ultrasonic generating module and an ultrasonic bubble-breaking mold 6, the latter connected to the ultrasonic generating module. Several mounting holes are provided on the support platform 1, and mounting seats 3 are fixed to these holes, with the ultrasonic generating module fixed to the mounting seats 3. Protective rollers 5 are mounted on both sides of the ultrasonic bubble-breaking mold 6 to guide the coated workpiece 9 across the upper surface of the mold. Preferably, the protective rollers 5 are carbon fiber rollers, possessing excellent strength and other properties. Preferably, the upper surface of the ultrasonic bubble-breaking mold 6 is close to the plane connecting the uppermost tangential surfaces of the two protective rollers 5, i.e., close to the surface of the coated workpiece 9 passing between the two protective rollers 5.
