Issue Date: | 14-Sep-2011 | Source: | 中国专利 ZL 200580006541.4 | Abstract: | An ultrasonic transducer driver has a giant magnetostrictive element, a fastener for holding the magnetostrictive element under mechanical pressure, a first field generator for providing a magnetic bias field, a second field generator for providing a magnetic drive field and a magnetic circuit for channelling the magnetic fields in the magnetostrictive element. An ultrasonic transducer for a bonding apparatus has a horn having a bonding tool at its smaller end and a mounting barrel adjoined onto it. The driver coupled to the larger end of the horn. 一种超声波换能器驱动器，所述驱动器具有大磁致伸缩元件、用于在 机械压力下保持大磁致伸缩元件的紧固件、用于提供偏磁场的第一磁场产 生器、用于提供磁性驱动场的第二磁场产生器、以及用于在磁致伸缩元件 中引导磁场通道的磁性回路。用于接合装置的超声波换能器具有：在较小 端处具有接合工具的角状部以及邻接至其上的安装桶状部。所述驱动器连 接到角状部的较大端。 |
