30khz Low impedance ultrasonic welding transducer For sealing
1. Low resonance impedance, high mechanical quality factor, high electro-acoustic conversion efficiency and large amplitude;
2, Few heat, large temperature range; small performance drift, stable work;
3. Good material reliability and long service life of the transducer.
How to select ultrasonic welding transducers depending on the following parameters:
① Resonant frequency: F, Unit: KHz
The frequency refers to the frequency measured by a transmission line method using a Ultrasonic frequency generator, a millivolt meter, or the frequency measured by a similar instrument such as an impedance characteristic analyzer. Generally referred to as small signal frequency. Opposite to this is the frequency of the machine, that is, the actual working frequency measured by the customer when the transducer is connected to the drive power supply through a cable. Because the customer's matching circuits are different, the same transducers with different drive power sources show different frequencies. Such frequencies cannot be used as an order basis.
② Transducer capacitance: CT, unit: PF
That is, the free capacitance of the transducer, which can generally be measured with a capacitor bridge at a frequency of 400Hz-1000Hz, or an impedance characteristic analyzer can be used. To make it simpler, the measurement with a general portable capacitance meter can also meet the requirements.
③ Working mode of transducer
Due to different processing methods and requirements, the working mode of the transducer can be roughly divided into continuous work (lace machine, CD sleeve machine, zipper machine, metal welding, etc.) and pulse type work (such as plastic welding machine). Different working methods are different. The requirements for transducers are different. Generally speaking, continuous work has almost no pause time, but the working current is not very large, pulse work is intermittent, there is a pause, but the instantaneous current is large. On average, the power in both states is significant.
④ Transducer type and high power
The complete machine manufacturer may have different regulations for the nominal power of machines for different purposes. In other words, the same transducer may be used on different machines with a nominal power that is different. In order to avoid ambiguity, the customer should specify the structure type of the transducer, such as column type, inverted horn type, etc., and the diameter and number of piezoelectric ceramic wafers.
⑤ Installation and fit dimensions
The ultrasonic horn materials, surface treatment methods, and shapes. The ultrasonic welding transducer is connected with an ultrasonic horn, the ultrasonic welding horn is connected with an ultrasonic mold, and the diameter, thickness, notch, or number and position of the screw holes at the flange of the ultrasonic horn.
