摘要
根据已知的切刀参数和相关柔性铰链四杆机构的设计原理,结合大量试验数据和实践经验,确定了全自动超声波压焊机的切丝机构的设计方案和结构组成,并利用UG软件创建了该机构各个零部件的三维实体模型,再通过必要的结构简化,将模型导入UG运动仿真模块进行运动仿真,着重分析和追踪该机构切刀尖的运动趋势和轨迹,并与劈刀进行对比,以检验其运动过程中是否存在干涉现象,验证切丝机构结构设计的可行性和合理性,为优化切丝机构提供参考依据。
According to the known parameters and the theory of the four-barflexure hinge mechanism, and combination with a large amount of experimental results and experience data, the blueprint and structure of the cutter mechanism of the ultrasonic wire bonder are determined, and its 3D solid models are built in the modeling environment of UG software .Then simplify the structure , and perfarm the kincmatical simulation in the motion environment of UG software, focusing on analysis and trace of the movement of the wire cutter, compare with the trace of the bonding tool, in order to check its intervention with the bonding tool, prove the fe as ib ility and rationality of the structure ,and provide references for the optimization of the wire cutter mechanism.
