20khz 3000w high performance ultrasonic welding transducer for lace sewing

This transducer was customized for ultrasonic high power welding.

The transducer consists of a housing, a matching layer, a piezoceramic disk transducer, a backing, an extraction cable, and a Cymbal array receiver. The piezoelectric ceramic disk transducer is made of PZT-5 piezoelectric material with polarization direction polarization. The Cymbal array receiver consists of 8 to 16 Cymbal transducers, two metal rings and rubber gaskets. A piezoelectric ceramic disk transducer is used as a basic ultrasonic transducer for transmitting and receiving ultrasonic signals; a Cymbal array receiver is located above the disk piezoelectric transducer as an ultrasonic receiver for receiving the disk Doppler echo signals outside the transducer band. The working distance of the invention is greater than 35 m, the frequency bandwidth reaches 10 kHz, and the long-distance target moving at high speed can be detected.
Ultrasonic transducer application: mainly used in ultrasonic welding equipment, such as ultrasonic plastic welding machine, ultrasonic metal spot welding machine, ultrasonic plastic spot welding machine, high-power ultrasonic plastic welding machine, ultrasonic automotive interior parts spot welding machine, ultrasonic metal wire harness Welding machine, etc.
Ultrasonic transducer product features:
1. Large amplitude: The structure optimized by computer, the vibration speed ratio is high, the front cover amplitude is large; 2. The output is large: the voltage is larger than the unit area; 3. The power is large: under the action of the prestressed screw, The energy of piezoelectric ceramics is maximized; 4. Good heat resistance: low resonance impedance, low heat generation, wide temperature range; 5. high reliability: long service life; 6. high performance: high mechanical quality factor The electroacoustic conversion efficiency is high.
Ultrasonic transducer common problems:
1. The ultrasonic vibrator is damp. You can check the plug connected to the transducer with a megger. Check the insulation resistance value to judge the basic situation. Generally, the insulation resistance is greater than 5 megohms. If the insulation resistance value is not reached, the transducer is generally damp. The whole transducer (excluding the sprayed plastic case) can be placed in the oven for about 3 hours at 100 °C or used to remove moisture to the resistance value. Normal until now.
2, the transducer vibrator is fired, the ceramic material is broken, and it can be combined with the naked eye and the megohmmeter. Generally, as an emergency treatment measure, the individual damaged vibrator can be disconnected without affecting the normal use of other vibrators.
3, vibrator degumming, our transducer is made of cement, screw fastening double guarantee process, under normal circumstances.
4, stainless steel vibrating surface perforation, the general transducer can be used for 10 years at full load, the vibrating surface perforation may occur.

20Khz transducer Parameter datasheet

Description:

The transducer converts high-frequency electrical energy into high-frequency mechanical vibrations. And it contains several piezoelectric ceramic discs sandwiched under pressure between two metal blocks. Between each disc is a thin metal plate, which forms the electrode. When a sinusoidal electrical signal is fed to the transducer via the electrodes, the discs expand and contract, producing axial vibrations.

20Khz transducer widely used in high power welding&sealing system.Piezoelectric transducer is the electric charge that accumulates in certain solid materials in response to applied mechanical stress. It is key point of all ultrasonic equipment.The transducer decide the property of the machine.We can supply transducer, also transducer with house and booster.
