【中文摘要】
挑线机构为焊线机各部组件中至为重要的一部份，良好的挑线机构设计有助于焊线机达成
高速化、自动化及高精度化的目标。因此本研究的目的，在于以电脑模拟的方式，分析新
型挑线机构的动态响应，并讨论各项变因对于模拟结果的影响。
本研究的进行可分为以下几个步骤：首先以集质量的方式建立挑线机构的动态模型，再利
用Lagrange能量法推导挑线机构的非线性二阶微分动态方程式；接著以凸轮造成的从动件
受力为输入，并利用Adams-Bashforth predictor法求该动态方程式的解。最后改变挑线机
构运转速度、复位弹簧弹性系数、与从动件阻尼系数等变因，观察其对于从动件摆角、钢
嘴升程、以及钢嘴受力的影响。而本研究的方法及结果，可供挑线机构细部设计的参考，
并期望能提供国内电子构装设备业界些许的贡献。

【英文摘要】
The bonding head mechanism is the most important part of a wire-bonding
machine, and a well-designed bonding head mechanism can help the
wire-bonding
machine achieve the goal of automation, high speed, and high precision.
Therefore the destination of this research is to analyze the dynamic
response
of a new type bonding head mechanism by computer simulations, and the
effects
of a few variables to the simulation results are also discussed.
This research is following these steps: First a lumped-mass model of the
bonding head mechanism is set up; next, a set of equations of motion of
the
lumped-mass model are derived based on Lagrange’s method and solved
through
Adams-Bashforth Correction method. Finally, the variables of the cam
speed,
the elastic coefficient of return spring, the coefficient of
viscous/Coulomb
damping between the follower and the pivot are introduced, so that the
effects
on the follower’s angle, the wedge lift, and the force acting on the wedge
can be recorded. The results and methods of this research can be the
reference
for the detail design of the bonding head mechanism, and it is to be
wished
that the research can be helpful to the domestic electronic packaging
industry.
