【摘要】： 富士康科技集团是面向全球PC(Personal Computer个人电脑)产业提供电子连接器及线缆等产品的制造商。面对原材料费用,人力成本上升及新劳动法的出台,电子连接器及线缆生产商要保持并提高产品现有的利润空间,就必须进行自动化生产和工艺优化、降低产品生产工时;提高产品直通率(一次合格率)和降低废品率,才能不断降低生产成本和提升产品竞争力。 论文阐述了PC产业中线缆连接器(Conn.)主要焊接方式Hot-bar焊接及其应用特点。在激烈的产业竞争中,各接插件厂商为了提高产品质量,争相采用自动化焊接方式和优化接插件焊接工艺。其中美商Tyco(泰科),日商Marunix(丸仁),台商Wanshih(万旭),HI-TEK(桦晟),Acon(连展)等接插件组装厂商都先后采用Hot-bar焊接。另外,由于笔记本电脑向着轻、薄、小方向发展,同样对应的线缆的Conn.也向着Pitch更小,产品更薄的方向发展,要求Conn.的焊接水平会更高,基于Hot-bar焊接工艺的一系列优点及其温度稳定性,其已经成为自动焊接的主攻方向。 本文从富士康公司线缆连接器(Conn.)生产中推行Hot-bar焊接代替原先的手工焊接实际状况出发,讨论分析了Conn.采用Hot-bar焊接代替手工焊接的可行性,在此基础上对Conn. Hot-bar焊接的现状进行分析,统计分析了Conn. Hot-bar焊接不良的主要形式,论文对Conn. Hot-bar焊接的工艺参数进行假设检定,筛选出参数中的显著影响因子;筛选试验前对试验所使用的机台进行温度量测校验,通过试验建立了机台温度同量测电阻片之间的数学关系,实现了对线缆连接器焊接温度的有效监控。对筛选后的两个显著影响因子“焊接时间”和“焊接温度”,运用响应曲面设计进行了试验优化,确定最优焊接工艺参数;采用优化的焊接工艺参数进行了实际焊接试验,检验其有效性。通过生产线实际焊接试验证明,Conn. Hot-bar焊接的不良率在原先的基础上降低了10个百分点;从经济上看,每年可以为公司节约100多万RMB。同时提高了生产线产品良品率,降低了生产成本,提升了产品的市场竞争力。
[Abstract]:Foxconn Technology Group is a manufacturer of electronic connectors and cables for the global PC (Personal Computer PC industry. In the face of raw material cost, rising labor cost and the introduction of new labor law, manufacturers of electronic connectors and cables must carry out automatic production and process optimization to reduce production hours in order to maintain and improve the existing profit space of their products. Only by increasing the pass rate and reducing the scrap rate can the production cost and product competitiveness be continuously reduced. The (Conn.) of cable connector in PC industry is expounded in this paper. Main welding method Hot-bar welding and its application characteristics. In order to improve the quality of products, the manufacturers of connectors are competing to adopt automatic welding and optimize welding process in the fierce industrial competition. Among them, American Tyco, Japanese Marunix and Taiwanese Wanshih HI-TEK have adopted Hot-bar welding. In addition, as laptops develop in light, thin, and small directions, the same corresponding cable Conn. Also toward the direction of smaller Pitch and thinner products, Conn. is required Based on a series of advantages and temperature stability of Hot-bar welding process, it has become the main direction of automatic welding. This article is based on Foxconn cable connector (Conn.) The actual situation of Hot-bar welding instead of manual welding in production is discussed and analyzed.
