What kind of basic elements composed of the ultrasonic welding systems?
All ultrasonic welding systems are composed of the same basic elements:
1.A press, usually with a pneumatic or electric drive, to assemble two parts under pressure
2.A nest or anvil or fixture where the parts are placed and allowing the high frequency vibration to be directed to the interfaces
3.An ultrasonic stack composed of a converter or piezoelectric transducer, an optional booster and a sonotrode Horn. All three elements of the stack are specifically tuned to resonate at the same exact ultrasonic frequency (Typically 15, 20, 30, 35 or 40 kHz)
4.Converter: Converts the electrical signal into a mechanical vibration using piezo electric effect
5.Booster: Modifies the amplitude of the vibration mechanically. It is also used in standard systems to clamp the stack in the press.
6.Horn or sonotrode: Takes the shape of the part, also modifies the amplitude mechanically and Applies the mechanical vibration to the parts to be welded.
7.An electronic ultrasonic generator Power supply delivering a high power electric signal with frequency matching the resonance frequency of the stack.
8.A controller controlling the movement of the press and the delivery of the ultrasonic energy.
