초록

In an attempt to improve adhesion strength between glass and metal due to use of Pb-free solder as a sealant between glass and metal in the manufacturing process of vacuum insulation window glass to maintain the vacuum volume, ultrasonic energy is often applied during the process of Pb-free sealing. In this study, we propose an ultrasonic vibrator with a 4 mm end tip radius which performs resonance frequency of 60 kHz and 14 um or higher vibration displacement. A frequency variation due to applied pressure on piezo disks, which was excluded in the computer simulation, was verified experimentally, and we have demonstrated a 17 um vibration displacement at 50 V input through the performance test of a vibrator constructed with our specification.
