国内某涂装车间,机盖出现PVC胶泡问题通过对胶泡位置切角分析发现问题原因是装焊折边内部填充有空隙,在烤箱高温烘干过程中PVC被空隙中的气体膨胀形成胶泡。为了解决此问题,首先通过优化PVC材料和机器人涂胶参数,然后通过装焊车间调整折边和装焊胶填充参数消除空隙最终解决PVC胶泡问题。

There was one painting workshop in China car body hood area had PVC bubble issue.The PVC bubble area was cut find that this area have a gap between hemming and PVC material.When the PVC was heated in the oven,the air expand cause bubble.Firstly to optimize the PVC material and PVC robot parameter,further body shop optimize the hemming and glue filling to prevent the gap,finally the PVC bubble issue has been solved.
