AI Technical Summary

Technical Problem

In the existing ultrasonic rolling welding devices, the cantilever structure and diaphragm spring sheet of the welding head are not rigid enough, which makes it difficult to effectively transmit static pressure, the welding head is prone to bend and damaged, and the amplitude during welding decreases, affecting the welding quality and acoustics. System stability.

Method used

Design an ultrasonic rolling welding head, by setting a pressurized part on the outside of the welding head close to the vibration output part, so that the static pressure is directly input to the position of the welding head close to the vibration output part, and by adjusting the structure and component layout of the welding head, the vibration is optimized. The length ratio of the output part and the outer pressing part is increased, and the spoke holes and other designs are improved to improve the amplitude gain and rigidity of the welding head.

Benefits of technology

It effectively improves the amplitude gain of the welding head, reduces the risk of damage of the welding head, improves the welding quality and the stability of the acoustic system, and reduces the power loss of the components.
