Control method of ultrasonic welding system, ultrasonic welding system and storage medium

A control method of an ultrasonic welding system, comprising:

• detecting operation of the ultrasonic welding system immediately while the ultrasonic welding system is in a working state;
• acquiring a current working frequency of an ultrasonic generator in the ultrasonic welding system while the ultrasonic welding system is detected to complete a preset first operation every time, wherein the first operation is completing a welding operation of a preset number threshold value of workpieces and delaying a preset time threshold value;
• determining a current frequency searching range of the ultrasonic generator according to the current working frequency of the ultrasonic generator;
• controlling the ultrasonic generator to search for an anti-resonance point in the current frequency searching range;
• and
• adjusting the working frequency of the ultrasonic generator to be an anti-resonance point while the anti-resonance point is searched in the current frequency searching range.
