The organizational structure of ultrasonic welding machine includes transducer, generator, horn and welding joint. Each organizational component has a certain influence on welding. For example, the setting of the horn of the ultrasonic automatic welding machine can avoid the offset of the vibrating arm, because its welding is that the welding joint is in direct contact with the material, so unlike the hot plate welding machine, the cleanliness of the welding joint will also affect the welding quality. Today, we will talk in detail about the influence of the transducer on the ultrasonic welding machine.

The transducer of ultrasonic welding machine is an interface connecting electrical appliances and mechanical environment. It has certain characteristics. When the transducer is in the detuning state, the voltage and current at both ends are in phase. When it is in the detuning state, the current and voltage will no longer be in phase. When the resonant frequency of the transducer is less than the working frequency, the whole circuit of the ultrasonic automatic welding machine is capacitive and the current is in the state of leading phase. On the contrary, when the resonant frequency is greater than the working frequency, the circuit of ultrasonic welding machine presents inductance, and the current phase lags behind the voltage phase.

From the characteristics of the transducer of ultrasonic welding machine, it can be seen that when it is not loaded, its vibration is above the resonant frequency, which can be regarded as a pure resistance. However, if it works with load, the change of load will lead to the change of circuit parameters, and there will be a difference between the actual working frequency and the resonant frequency of the power supply. At this time, the welding efficiency will become lower than that of the hot plate welding machine, and the overall welding quality and effect will be affected. At this time, the body of the ultrasonic welding machine is also easy to be damaged.

By explaining the characteristics of the transducer of ultrasonic welding machine, we can understand its impact on the whole welding equipment. When it works with load, it will directly reduce the welding efficiency. When its efficiency becomes low, the effect of welding is worse than that of hot plate welding machine, so the influence of transducer can not be ignored. We need to track and control the transducer of the ultrasonic automatic welding machine and control the operation so that it is not in the state of load as far as possible. I hope the above analysis of the energy converter can let you understand its impact on the ultrasonic welding machine and better maintain the welding quality.
