Cross-shaped ultrasonic wave amplitude modulator

Technical Field

The utility model relates to an ultrasonic bonding equipment field, concretely relates to cross ultrasonic wave amplitude modulator.

Background

Ultrasonic wave amplitude modulators utilize the acoustic resonance characteristics of ultrasonic waves as they propagate through a medium to effect the transfer of ultrasonic energy and the change of output amplitude in ultrasonic welding applications. When the length of the ultrasonic wave amplitude modulator is close to the half wavelength of the ultrasonic wave with a certain frequency, the ultrasonic wave amplitude modulator generates simple harmonic vibration, and at the moment, the acoustic impedance is minimum, and the energy transfer efficiency is highest. The adjustment of the parameters of the ultrasonic wave amplitude modulator is realized by trimming the external dimensions of the ultrasonic wave amplitude modulator.

In the use process of ultrasonic plastic flexible welding, when plastic products such as automobile door panels, instrument panels, A/B columns and the like are welded, due to the fact that the welded products are complex in structure, a robot needs to replace different ultrasonic welding heads to complete welding. An original ultrasonic amplitude modulator can only be assembled with one welding head at a time, as shown in fig. 1, the ultrasonic amplitude modulator comprises an ultrasonic transducer 1 and an ultrasonic welding head 2, when the ultrasonic amplitude modulator is used for welding products with different structures and shapes, different welding heads need to be replaced, and a welding head replacing system needs to be designed and installed. Each system requires a separate welding unit. After each welding, the robot grasps different welding units to complete the welding. Thereby increasing the complexity of the equipment and the processing cost, prolonging the welding time and even influencing the delivery period.
