<p>PURPOSE:To shorten the metal bonding time and improve the sureness by employing a horn structure to synthesizing longitudinal vibration and torsional vibration to realize circular vibration. CONSTITUTION:An ultrasonic welding apparatus is constituted of a screw vibration horn 1, horn (HL) 2, horn (Ht) 3, ultrasonic vibrator (VL) 4, ultrasonic vibrator (Vt) 5, alternating current power supply 6, variable phase circuit (P) 7, short bar (S) 8, anvil 9, die 10, arm 11, and cylinder 12. The vibration of the horn (HL) 2 and that of the horn (Ht) 3 are synthesized using the screw vibration horn 1 to generate circular vibration.</p> |
