摘要
超声波焊接系统工作效率的高低主要取决于该系统中超声波电源、匹配网络及换能器组件3大部分是否工作在谐振频率点附近,其工作频率越接近谐振频率,电源的工作效率将越高。限于换能器行业材料和技术的原因,所生产的换能器和匹配网络部件的性能参数难以达到高度一致,对超声波电源的适应性提出了较高要求。此处设计了一款基于数字信号处理(DSP)和DWIN图形应用软件(DGUS)的双处理器控制全数字超声波焊接电源,通过友好的人机界面设置电源工作频率范围及其他相关参数,电源自动匹配换能器及网络,锁定超声波电源输出电流和输出电压的相位差及工作频率,广泛提高了超声波焊接电源的适应性。
The working efficiency of ultrasonic welding system mainly depends on whether the three parts of ultrasonic power supply, matching network and transducer component work near the resonance frequency point.The closer the system working frequency is to the resonant frequency, the higher the efficiency of the power supply will be.Because of the limitations on the material and technology of transducer industry, the performance parameters of transducer and matched network components are difficult to reach a high degree of conformity, and higher requirements for the adaptability of ultrasonic power supply are put forward.A full digital ultrasonic welding power source controlled by dual processor based on digital signal processing（DSP） and DWIN graphic utilized software（DGUS） is designed. Through the settings of the power supply range of working frequency and other related parameters on the human-machine interface,the power supply automatically matching transducer and matching network, locking the working frequency and the phase difference between current and voltage.The adaptability of ultrasonic welding power supply is widely improved.
