摘　　要：底涂工艺是以汽车安全玻璃作为注塑嵌件的安装托架注塑粘结智能化生产的关键技术,底涂工艺主要受玻璃的定位和机械手涂布质量影响。针对玻璃的定位,提出采用自锁角的逐步筛选法得出分区域的3点有效定位方法,解决超定位带来的成本问题;同时,对机械手的"Z"字形的底涂路径进行折弯轨迹优化,实现了机械手底涂轨迹的连续光滑,保证机械手在底涂过程中运动的平稳性。采用上述底涂工艺进行安装托架的注塑粘结,得到的底涂厚度控制在20μm,且制备的安全玻璃安装托架的粘结质量良好,为实际生产起到了指导作用。The primer coating process was the key technology in the intelligent injection molding of mounting brackets with automobile safety-glass used as the injection molding insert. The process was mainly affected by the positioning of the glass and the coating quality of the manipulator. Aiming at the positioning of the glass, a step-by-step screening method based on the self-locking angle was proposed to obtain the 3-point effective positioning method, which reduced the cost caused by repeated positioning. Meanwhile, the ＂Z＂ shaped coating path of the manipulator received bending trajectory optimization, which helped realize the continuous smoothness of the trajectory of the primer coating of the manipulator and ensured the smooth movement of the manipulator during the priming coating process. The primer coating process used for injection molding and bonding of the mounting bracket helped produce primer coating with a thickness of 201xm and safety-glass mounting brackets with superior adhesive quality. The above-mentioned process can provide guidance for the actual production.
