Ultrasonic welding machine is a special equipment that utilizes high-frequency vibration energy to weld, emboss, or seal plastic.
Ultrasonic welding machine transducer is one of the components used in ultrasonic welding machines, whose quality directly affects the emission effect and service life of ultrasonic waves.
The ultrasonic welding head is composed of a transducer and two resonance plates, which are made of aluminum magnesium alloy materials (some also use stainless steel materials).
A piezoelectric ceramic element is placed on the resonance plate, and when a voltage is applied, mechanical vibration is generated and converted into electrical signals.
Currently, there are two main types of ultrasound generating devices sold on the market:
One is an electronic tube type; The other is wafer type. The electronic tube type generator has complex structure, large volume, heavy weight, and high cost,
Has been phased out; The wafer type has the advantages of small size, light weight, and low cost,
Therefore, it is widely used in various types of ultrasonic generators.
Principle of crystal oscillator:
Due to the high amplification factor of transistors (typically over 100 times),
Therefore, the load requirements are also very high (typically from tens of watts to thousands of watts), so discrete devices are usually used to form oscillation circuits to meet the requirements.
Ultrasonic products are widely used in various industries such as plastic, non-woven fabrics, packaging, printing consumables, medical treatment, electronic appliances, stationery and toys; Products using ultrasonic welding can be seen everywhere in our daily life
