【摘要】 随着硬盘在信息产业中的重要性的空前提升和微电子技术的不断发展,硬盘的各种性能指标得到了不断提高,作为硬盘的重要组成部分,HSA磁头臂组件在生产中以人工焊接G-Pin/VC-Pin导通磁头和软线路板的技术不能满足硬盘生产效率的要求,迫切需要改造和换代,企业迫切需要开发一种新的满足磁头臂组件微焊接问题要求的自动化钎焊设备。目前在国内外市场上用于HSA导通磁头和软线路板工序的自动化设备才刚刚起步,有关研究也尚未见报道。本文从选取焊接方式着手,选取采用软钎焊技术并提出磁头臂组件全自动钎焊机的研制要求,研究一种低成本、高效率的HSA全自动钎焊机。HSA全自动钎焊机的系统组成包括运动定位功能模块、视觉对准获取模块、激光加工控制模块、用户交互四个功能模块。进行了产品样机的结构设计,详细研究分析机构设计原理和结构实现并在全自动钎焊机CAD设计工程中运用参数化设计思想。对焊接关键部位焊嘴和质量影响主要因素锡球进行了热力分析,根据焊接过程非线性的特点,确定基本的求解方法;本文对关键加工工艺部位焊嘴进行热力分析,利用MARC软件进行热力计算分析。最后实验数据对优化激光焊接的工艺参数,提高焊接质量有着积极的参考意义。通过模拟和实验的手段找出优化锡球钎焊的方法,分析影响锡球焊接质量的因素,并从工艺实验中验证改进效果,达到改进焊接效果的目的。更多还原

【Abstract】 With the importance of the unprecedented improvement and continuous development of the hard drive in microelectronic technology, the various performance indicators of the hard drive has been continuously improved. As an important component of the hard disk, The technology of the artificial soldering G-Pin/VC-Pin turn heads and soft circuit board in HSA production can not meet the requirements of efficiency in the hard disk production. An urgent need to transform and regenerate, and the urgent need for businesses to develop a new micro-welding problem to meet the HSA requirements of automated soldering equipment.The main thesis include:SMT discussed in detail the development of a comprehensive overview of laser technology and its classification and the subject of soldering techniques used in the selection of proposed development of HSA automatic brazing machine requirements.HSA is designed automatic soldering machine’s overall program to study the JSBB technical principles and HSA automatic brazing machine motion positioning system consists of functional modules, visual alignment acquisition module, laser processing control module, user interaction four functional blocks. Carried out the structural design of the product prototype, discusses parametric design ideas in HSA automatic soldering machine in the use of CAD design engineering.The key parts of the soldering nozzle soldering and quality of the main factors affecting solder ball thermal analysis carried out, based on the soldering geometrical nonlinearity, material nonlinearity and deformation characteristics of non-linear analysis to determine the basic solution method; In this paper, the key to Processing part of welding nozzle for coupled thermo-mechanical analysis, using MARC software coupled thermo-mechanical analysis of a mathematical model calculations, boundary conditions, carried out analysis of heat conduction and thermal stress analysis.This thesis analyzes the impact of solder ball welding quality factors, through simulation and experiment to find the means to optimize the solder ball soldering method, and have been verified by experiment from the process to improve results, achieving the purpose of improving the welding effect.更多还原
