ONE WAVE-LENGTH LONGITUDINAL VIBRATION MODE DIAGONAL SLIT COMPLEX VIBRATION CONVERTER FOR ULTRASONIC COMPLEX VIBRATION WELDING SYSTEM - 27 KHZ AND 40 KHZ COMPLEX VIBRATION WELDING SYSTEMS USING VARIOUS EXCHANGEABLE WELDING TIPS -

摘要

Ultrasonic complex vibration welding systems with complex vibration converter using two-dimensional vibration stress were proved significantly superior welding method compared with conventional welding with linear vibration. Ultrasonic complex vibration welding systems are significantly effective for welding of same and different metal parts and many lapped foils such as aluminum and copper electrode foils and terminals which are essential for electronic devices, Li-ion battery or EDLC electrodes and other various industry fields. 19.5 kHz complex vibration systems using various complex vibration welding tips which are exchangeable by a connecting bolt have been proved very useful for various welding specimens. But, higher frequency system is desired to improve welding characteristics for smaller and special welding specimens. To decrease required vibration amplitude and also vibration damage of welding specimen, 27 kHz and 40 kHz complex vibration welding systems using various exchangeable welding tips were developed newly.
