Upside Down Trumpet Type 20khz 1500W Ultrasonic Welding Transducer with 10 Micron Amplitude

Description:

Piezoelectric ceramic transducers are the core components of ultrasonic products, and their quality directly affects the performance of the entire ultrasonic equipment. The transducers of Hangzhou Qianrong Automation Equipment Co., Ltd. are strictly tested by piezoelectric ceramic evaluation system. The impedance analyzer can be used to evaluate piezoelectric ceramic sheets, piezoelectric transducers and the entire vibration system (transducer plus amplitude). Performance of various device devices such as rods and molds.

Specifications:

There are four main aspects of matching the transducer to the driving power source, namely impedance matching, frequency matching, power matching, and capacitive reactance matching.

Frequency matching is also very important. This is primarily because the ultrasonic transducer can only operate at its resonant frequency point, so the drive power, horn, and welding die (tool head) should all operate at this frequency. In general, we hope that the difference is no more than ± 0.1khz, and it is better to be smaller. We strongly recommend that the frequency of the matching welding tool (welding head) be lower than the vibration sub-frequency by about 0.1khz (small signal frequency). That is to say, if the frequency of the original vibrator small signal measurement is 14.85 khz, it is most ideal to measure the frequency after connecting the mold to 14.75 khz. At the same time, it should be considered that after the ultrasonic transducer is connected to the horn and the die head, the resonance frequency peak of the system becomes very sharp, that is, the bandwidth is very narrow, the mechanical quality factor is large, and the frequency offset will cause the impedance to be very high. A big increase. Expressed on the drive power supply is the power supply (amplitude meter power) or overload protection. If it is just an empty load adjustment at this time, it is likely to cause the wafer to be misaligned, the wafer is broken or the center screw is broken.
Power matching and impedance matching are mainly based on the fact that the ultrasonic welding system is a gap type operation, the load changes greatly, and there must be sufficient power output during welding, and the minimum amplitude should be controlled at no load. Otherwise, as mentioned earlier, if the input is large at no load, the transducer is damaged. When the load is full, the power will not go up, and the welding is not strong or useless.
