Product Description
Working principle
Based on the piezoelectric effect, when a high-frequency electrical signal passes through a piezoelectric ceramic material, a charge distribution is generated on its surface to form an electric field, causing deformation of the piezoelectric ceramic. The electrical signal is converted into a mechanical vibration signal, which is then amplified by a variable amplitude rod and transmitted to the oscillator head.
Structural composition
Piezoelectric ceramic component: It is the core of the transducer, which realizes the conversion of electrical energy and mechanical energy. Commonly used materials include barium titanate, lead zirconate titanate, etc.
Front and rear metal cover plates: protect piezoelectric ceramic components, enhance structural strength, and help transmit and amplify vibration energy.
Pre stressing screw: used to fasten various components, allowing piezoelectric ceramic elements to work under pre stressing, improving stability and reliability.
Electrode pad: Connect external circuits, introduce electrical signals into piezoelectric ceramic components, or collect generated electrical signals.
Insulated tube: It serves as insulation to prevent short circuits between components and ensure the normal operation of the transducer.
Performance characteristics
High efficiency: The frequency of 15kHz enables the transducer to quickly convert ultrasonic energy into mechanical vibration energy, with an electroacoustic conversion efficiency of over 90%.
Large amplitude: The oscillator has a high vibration speed, and the amplitude of the front cover plate is 25% larger than that of ordinary transducers, which can drive large ultrasonic tool heads.
High precision: welding energy is concentrated, action time is short, welding joint quality is high, and precision can reach millimeter level.
Widely applicable: It can be used for welding various materials such as plastic, metal, glass, etc., and is widely used in fields such as automobile manufacturing, electronic appliances, medical equipment, packaging, etc.
Environmental protection and energy conservation: The welding process does not require the addition of auxiliary materials, resulting in low energy consumption and reduced environmental pollution, which is conducive to green production.
Application area
Plastic welding: It can weld larger workpieces such as electric mosquito swatters, car lights, vacuum cleaners, speakers, instrument panels, and other plastic components.
Metal processing: used for welding, surface treatment, etc. of metal materials, such as connecting battery cells in battery pack manufacturing.
Medical devices: can be used for connecting surgical instruments, dental materials, etc., ensuring the accuracy and reliability of the instruments.
