    • An ultrasonic welding system and a method are provided. The system includes an ultrasonic welding device and a controller that generates control signals for inducing the device to form a first weld joint. The system further includes a power adjusting unit having a desired output power level curve indicating desired power levels over time for obtaining a desired weld joint. The unit receives data from the controller indicating power levels when forming the first weld joint. The unit compares a power level output by the controller at a first time with an associated power level of the curve at the first time, and induces the controller to increase the power level at a second time if the power level output by the controller at the first time is less than the associated power level of the curve at the first time.
    • 提供超声波焊接系统和方法。 该系统包括超声波焊接装置和控制器,其产生用于诱导装置形成第一焊接接头的控制信号。 该系统还包括功率调节单元,其具有期望的输出功率水平曲线,其指示期望的功率水平随时间而获得期望的焊接接头。 该单元从控制器接收指示形成第一焊接接头时的功率水平的数据。 该单元将控制器的第一时间输出的功率电平与第一时间的曲线的相关联的功率电平进行比较,并且如果控制器输出的功率电平在第二时间引起控制器在第二时间增加功率电平 第一次小于第一次曲线的相关功率水平。
