1khz-5mhz Ultrasonic Impedance Analysis Of Ultrasonic Welding Transducer / Horn
The applications of impedance curve and admittance circle in the processing and production of ultrasonic devices are as follows:
● Ultrasonic Transducer: the admittance circle shall be free of parasitic circles, the resonant frequency shall be close to the design frequency as much as possible, the dynamic impedance shall be low, the quality factor Qm shall be close to the design requirements, and the capacitance shall match the circuit.
● piezoelectric ceramic chip: the device can be judged directly from the admittance circle diagram and logarithmic coordinates. If there are delaminations or cracks in the ceramic chip, the logarithmic curve will have multiple peaks. Multiple parasitic small circles appear on the admittance circle graph.
● Ultrasonic horn and mold: whether the design, processing and assembly are reasonable or defective can be seen directly from the admittance circle diagram.
● Ultrasonic Welding Machine: during production and processing, the results of admittance circle are used to analyze the state of the welding machine, and the existing problems of the welding machine are found through parameter and graphic analysis.
● Ultrasonic Cleaning Machine: During production and processing, the selection of vibrators requires their vibration performance to be as consistent as possible (bandwidth, quality factor, resonance frequency, dynamic impedance). On the admittance circle diagram, there is no parasitic circle or parasitic circle near the resonance point as far as possible. The admittance circle can be used to analyze and measure the impedance characteristics of the transducer after manufacturing, incoming material inspection, bonding, and cleaning machine. The whole machine measurement of the cleaning machine can calibrate the resonant frequency and static capacitance of the machine, so as to match the power supply, and can analyze the characteristics of its new resonant point, impedance, capacitance after water injection and vibration mode of the whole machine.
