Parameter
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.
