摘 要: 本文基于ICL8038压控振荡器与CD4046锁相芯片技术,以AT89S52单片机作为控制核心,设计了一种面向金丝球焊线机的功率超声电源。此电源系统主电路输出功率、时间可调的超声频交流电;能实现自动频率跟踪;具有简单轻便、成本低廉的特点。文中较为详细地分析了功率超声电源的设计,压电换能器匹配调谐的原理以及控制方法。 A kind of power ultrasonic supply which based on ICL8038 Voltage Controlled Oscillator, CD4046 Phase-Locked Loop, and Microcontroller Unit AT89S52 was designed for Gold Wire Bonder. The main circuit of the supply system produces power supersonic AC output with changeable power and time; it performs the control of frequency auto-tracking; and it is simple, smaller, lighter, and not expensive. The design of power ultrasonic supply, the principles and control approaches of piezoelectric transducer were detailed analyzed in this paper.
