Description

 

The transducer part is composed of three parts: transducer (TRANSDUCER); amplifier (also known as secondary rod, horn, BOOSTER); welding head (also known as mold/fixture, HORN or SONTRODE).

Transducer (transducer): The role of the transducer is to convert electrical signals into mechanical vibration signals. There are two physical effects in converting electrical signals into mechanical vibration signals. a: Magnetostrictive effect. b: The reverse effect of the piezoelectric effect. Magnetostrictive effect is often used in early ultrasonic applications. Its advantage is large achievable power capacity, but its disadvantage is low conversion efficiency, difficult production, and difficulty in mass industrial production. Since the invention of the piezoelectric ceramic transducer, the application of the inverse effect of the piezoelectric effect has been widely adopted. Piezoelectric ceramic transducers have the advantages of high conversion efficiency and mass production, but the disadvantage is that the power capacity is small. Existing ultrasonic machines usually use piezoelectric ceramic transducers. Piezoelectric ceramic transducers are made by sandwiching piezoelectric ceramics between two metal front and rear load blocks and tightly connecting them with screws. The output amplitude of a typical sensor is about 10μm.

The ultrasonic amplifier is an important part of the ultrasonic vibration system. The main function in the vibration system is to amplify the displacement and speed of the particle of mechanical vibration, and concentrate the ultrasonic energy on a small area to collect energy. It is also called ultrasonic shift lever and ultrasonic energy gathering. Device.

Ultrasonic Welding Head Mould (HORN): The function of the ultrasonic mould is for special plastic parts, conforming to the appearance of plastic parts, extrusion molding category and other regulations.

 

Working temperature 


Ultrasonic transducers will generate heat when used, which is mainly caused by three reasons. One is that the workpiece to be welded will heat up or the material processed by ultrasonic will heat up, or the mold (tool head) and the horn will heat up for a long time, and these heat will be transferred to the transducer. The second is the power loss of the transducer itself. Since 100% energy conversion efficiency cannot be achieved, the part of energy lost must be converted into heat. The temperature rise will cause the parameter of the ultrasonic transducer to change, which will gradually deviate from the best matching state. What is more serious is that the temperature rise will cause the deterioration of the performance of the piezoelectric ceramic wafer. This in turn makes the ultrasonic transducer work worse and heat up faster, which is a vicious circle. Therefore, we must provide good cooling conditions for the ultrasonic transducer, which is generally air-cooled at room temperature; if necessary, cold-air air cooling can also be used. Under normal conditions, the temperature rise caused by these two points is also normal. Under normal cooling conditions, there will be no major problems.

 

Features of ultrasonic transducer


◆ High performance: high mechanical Q value, electro-acoustic conversion efficiency as high as 90% or more.
◆ Large amplitude: The vibrator has a high vibration speed, and the vibration amplitude is increased by more than 50% compared with the magnetostrictive transducer.
◆ Heat resistance: using high-quality materials, good heat resistance, low resonance impedance, and low heat generation.
◆ Strong structure: high-quality standard steel bolts are used for fastening, and the reliability is high.
◆ Electrical parameters: unique production technology, digital equipment processing and assembly, high parameter performance and good consistency.
