摘　　要：针对新能源汽车零配件实际应用中现有自动化生产设备柔性化程度低、涂胶复合精度差等问题,通过深入研究涂胶、压合工艺,研制出高精准柔性化涂胶压合线体。首先,分析了自动涂胶压合工作原理,设计了涂胶压合线体整体结构及布局,主要包括涂胶工作站和翻转复合工作站;接着设计了涂胶工作站机器人涂胶单元及翻转复合工作站的加热系统、仿形胎膜、翻转压合机构及下顶出式快速换模机构;然后开发了线体控制系统软件,控制系统通过关键工艺参数关联控制涂胶与翻转工作站之间信号互锁,提高了设备整体生产可靠性;最后,通过整体调试及性能分析,验证了所研发线体的整体性能。经过客户现场实际应用,线体可稳定实现汽车B柱板、激光雷达罩及底座3个产品的柔性化生产,涂胶后的外板胶线宽度、高度误差均在±0.25 mm以内,产品内外板关键接合面胶粘剂连续均匀填充,连续生产1 000套产品,产品合格率不低于99%。In response to the problems of low flexibility of existing automated production equipment and poor precision of coating and lamination in the practical application of new energy vehicle parts,a high-precision flexible coating and lamination line body has been developed through in-depth research on coating and lamination processes.Firstly,the working principle of automatic gluing and pressing is analyzed,and the overall structure and layout of the gluing and pressing line were designed,mainly including the gluing workstation and the flipping composite workstation.Subsequently,a detailed design is carried out for the robot gluing unit of the gluing workstation and the heating system of the flipping composite workstation,the profiling tire film,the flipping and pressing mechanism,and the bottom ejecting rapid mold changing mechanism.Then a line control system software is developed,which controls the signal interlocking between the gluing and flipping workstations through key process parameter correlation,improving the overall production reliability of the equipment.Finally,the overall performance of the developed line is verified through overall debugging and performance analysis.After practical application by customers on site,the line can stably achieve flexible production of three products:car B-pillar panel,laser radar cover,and base.The width and height errors of the adhesive line on the outer plate after coating are within±0.25 mm.The key joint surfaces of the inner and outer plates of the product are continuously and evenly filled with adhesive,and 1000 sets of products are continuously produced.The product qualification rate shall not be less than 99%.
