The Design and Analysis of Ultrasonic Roll Welding Head and Tool

Abstract:

Solar panels conduct electricity through aluminum strips on substrate surfaces. Ultrasonic roll welding can weld the conductive aluminum strips onto the glass substrates. This paper illustrates vibration characteristics and optimal design of amplitude horns used in the ultrasonic welding roll. Based on theoretical equations, this study used the ANSYS software to establish the parametric model according to design requirements. With the parametric model as the initial design, this study conducted modal analysis and harmonic analysis to obtain the vertical mode and disc bending mode of the horn, and measured the resonant frequency, amplitude amplification rate and stress distribution. Finally, this study implemented and verified the optimal coupled disc tool of the ultrasonic horn.
