| 摘要 |
In the present invention, disclosed is an apparatus for driving a ultrasonic welding machine, including a vibration device installed in a horn of the welding machine which generates mechanical vibrations based on electrical vibration signals; an oscillation part which generates driving frequency to drive the vibration device; and an amplification part which increases pressure of the driving frequency generated from the oscillation part and outputs the electrical vibration signals in the vibration device by resonating, so that the driving frequency is located between a serial resonance points and parallel resonance points. |
