What is ultrasonic transducer
Ultrasonic transducer: A device that can convert high-frequency
electrical energy into mechanical energy. Generally there are
magnetostrictive and piezoelectric ceramic types. The power is
output to the ultrasonic generator and then to the ultrasonic
welding transducer. Generally, the ultrasonic can be generated
through the ultrasonic derivation device.
The composition of an ultrasonic welding transducer includes a
housing, a matching layer, that is, a sound window, a piezoelectric
ceramic disc transducer, a backing, and a lead-out cable, which is
characterized in that it also includes an array receiver, which
consists of a lead-out cable, a transducer, Metal ring and rubber
washer.
The principle and function of ultrasonic transducers: Ultrasonic
transducers are piezoelectric ceramics that resonate at ultrasonic
frequencies. The piezoelectric effect of materials converts
electrical signals into mechanical vibrations. Ultrasonic
transducers are energy conversion devices. Its function is to
convert the input power into mechanical power (that is, ultrasonic
waves) and then transfer it out. It consumes a small part of power
by itself.
Types of ultrasonic transducers: They can be divided into
piezoelectric transducers, sandwich transducers, cylindrical transducers, inverted horn
transducers, and so on.

How to Evaluate the quality of the ultrasonic transducer?
First, it can be identified from the manufacturing process and
appearance of the ultrasonic transducer; the ultrasonic transducer
indirectly shows that the company pays attention to the quality of
the product, and the production and quality with good technology
and appearance will naturally be better . And the design process
indirectly affects the quality of production.
Second, it can be identified based on the process design and application
data of the ultrasonic transducer; however, this requires a good
understanding of the transducer data and rich experience. Whether
the design is reasonable should be determined based on the
selection of data. The quality of the data indirectly affects the
quality of the product, and it may not be copied according to the
board. The origin of the data with the specifications is not the
same, the quality varies greatly, and no matter how good the data
is, it also makes a good product.
Third, parameter detection by impedence analyzer; test whether the
parameters of the ultrasonic transducer can match the parameters of
the electrical box, and whether it can achieve the desired effect.
Fourth, work on the ultrasonic welding machine
1-Power input experiment: This method can detect the match between
the transducer and the ultrasonic generator, and at the same time
can reflect the power input of the ultrasonic generator and the
transducer load. The larger the mold belt, the better the task
effect and the better the power input. Strong. (The current can
only reflect the input efficiency and does not represent the power
of the device)
2- Fluctuation experiment (imitation aging experiment): Take the
equipment extra load to detect the power input fluctuation of the
ultrasonic generator and transducer.
3- Overload operation test: test the fluctuation of product quality
and life. This test only needs to take extra load to continue
discontinuous operation for 8 hours.
