汽车涂装车间旋转胶枪PVC残胶优化

Swirl Gun PVC Residue Optimization in Automobile Paint Shop

为解决后围残胶进入总装车间干涉安装的问题,对聚氯乙烯(PVC)材料、枪嘴温度和机器人喷涂程序进行优化:在不影响涂胶密封性和外观的前提下,提高PVC材料相对粘度和屈服值;降低枪嘴出胶温度,减少残胶的产生;取消后围位置的一对开关枪点,将2道不同的胶合并成同一道胶。结果表明,以上措施消除了后围处PVC残胶,避免了对总装安装平面的干涉影响。

To solve the quality issues that rear quarter PVC residue interference with assembly shop installation,PVC material,nozzle temperature and robot application program are optimized as following.For PVC material,Relevant viscosity and yield value with the precondition of no influence to the tightness and appearance are increased;The nozzle temperature is reduced and the PVC residue amount is decreased;The gun on-and-off points of rear quarter are cancelled and two adjacent seams are combined to one big seam.The result indicates that the solutions above remove the PVC residue on rear quarter and avoid the PVC interference to assembly installation surface.
