The invention provides an ultrasonic generation system and an ultrasonic welding machine, and relates to the technical field of ultrasonic waves. The ultrasonic generation system provided by the invention comprises a controller unit, a phase-shifted full-bridge unit, a tuning unit and a positive feedback unit, the controller unit is in isolated connection with the phase-shifted full-bridge unit and is used for sending a control signal to a driving end of the phase-shifted full-bridge unit; the phase-shifted full-bridge unit is used for converting an input voltage into an adjustable output voltage; the input end of the tuning unit is connected with the output end of the phase-shifted full-bridge unit, and the tuning unit is used for adjusting the amplitude of the output voltage; the input end of the positive feedback unit is connected with the output end of the tuning unit, the output end of the positive feedback unit is connected with the phase-shifted full-bridge unit, and the positive feedback unit is used for compensating the input voltage to obtain the output voltage with the same amplitude. By means of the ultrasonic generating system, the output power linear adjusting precision and the welding quality can be improved.
Description
technical field [0001] The present application relates to the field of ultrasonic technology, in particular to an ultrasonic generating system and an ultrasonic welding machine. Background technique [0002] At present, welding technology is widely used in aerospace, bridge shipbuilding, pressure vessels, metal structures and other fields, and with the continuous advancement of modern technology, the requirements for welding quality and welding efficiency are getting higher and higher. [0003] With the development and progress of science and technology, welding methods are also constantly improving. In order to improve welding quality and welding efficiency, a variety of composite welding methods have been designed, and ultrasonic welding is one of them. Ultrasonic welding is the use of high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects are rubbed against each other to form fusion between m...
