Abstract: This article discusses the process of analyzing and solving problems based on actual production cases. Firstly, the article introduced the general situation for this case. For bodyshop glue one-side bond issue after oven baking, showed the glue function, defect format, different result for different glue and the surface status of car body parts. Secondly, started the specific analysis process, including comparison analysis, concentrate analysis, group comparison analysis, and generally concluded the main factor. Finally, through verifying the main factor, find the long term solution to solve this issue. The analysis method used in this article has important reference value for quality issues in production. It can effectively solve car issue especially for gap and transition issue, reduce cost, optimize quality and improve work efficiency.
Keywords: Bodyshop glue; One-side bond; Destructive Test; Analysis
前言
质量是企业生存和发展的根本,如何高效准确地找到根本原因,解决质量问题是各公司相关部门在探索的方向。质量问题分析方法,主要有8D方法,5W2H方法,以及六西格玛黑带分析方法等。本文采用Delterlyze 绿带分析方法解决车辆质量问题。Delterlyze 绿带分析方法是一种高效的质量分析工具,核心思路是通过好坏结果的对比和分析,逐步找到根本原因解决质量问题。
某車型为德国引进车型,前期试装阶段发现有大概率RA310胶段单面粘缺陷,车辆出现单面粘的概率为100%,单车各胶段出现单面粘的概率为30%。为了规避胶段失效引起的噪音、腐蚀等风险,保证成品车的质量,需要尽快从根本上解决此问题。
1 项目背景
1.1 缺陷描述
该车型车身,自从第一辆剔试车身考核以来,左右侧围涂RA310的胶段就会出现单面粘的缺陷,整车胶段缺陷率为30%。……
