35khz Guidance of ultrasonic welding horn calculation tuning, design and test

Introduction:

Frequently, an ultrasonic horn has a transitional section with a longitudinal cross-section profile that converges towards the output end. Thus, the horn’s longitudinal oscillation amplitude increases towards the output end, while the area of its transverse cross-section decreases. Ultrasonic horns of this type are used primarily as parts of various ultrasonic instruments for ultrasonic welding, ultrasonic soldering, cutting, making surgical tools, molten metal treatment, etc. Converging ultrasonic horns are also commonly included in laboratory liquid processors used for a variety of process studies, including sonochemical, emulsification, dispersing and many others^.

How to test the horn?

The ultrasonic welding machine of any company has a center frequency, such as 20KHz, 15KHZ, 30KHZ, 40 KHz, etc. The working frequency of the ultrasonic welding machine is mainly composed of an ultrasonic transducer (Transducer), an ultrasonic horn (Booster), and a welding horn. The mechanical resonance frequency is determined. The frequency of the generator is adjusted according to the mechanical resonance frequency to achieve uniformity, so that the welding horn works in the resonance state, and each part is designed as a half-wavelength resonance body.

At present, the ultrasonic vibration system generally used is a λ / 2 resonance system, that is, a half-wavelength resonance system. Therefore, the design is also based on λ / 2, which can be used as 1λ, 1λ / 2, 2λ, 2λ2 ,,. In theory, under the condition that the system power can promote the welding horn, the welding horncan be designed as long as it is a multiple of λ / 2, so we can also call this type of welding horn a λ / 2 resonance welding horn.

Ultrasonic Impedance analyzer

The device is installed on the ultrasonic transducer&booster , and the output line is connected to the impedance analyzer, and then the frequency range is searched. The lowest impedance and good waveform are the resonance frequency. At the test frequency of the impedance analyzer, the frequency and vibration state of the welding horn can be accurately seen; and the search frequency range can be set. For newly developed ones, the shape and height cannot be judged at the initial test frequency, which can help designers Understanding the vibration state and frequency, it is an indispensable test method for the research and test of welding horns.
