可以说自动点胶机的出现带动了电子、数码、医疗行业的快速发展,加速了科技时代的进步,而喷射点胶机的出现使这些行业的点胶工艺更加精准、精致,实现了精细元件的点胶工艺。喷射点胶机的出现固然是好处诸多,却也有不可抗因素存在,小编来讲讲喷射点胶机工艺存在的缺陷和对应的解决方法:

1.喷射点胶机针头距离校准

根据产品点胶量大小选择相应的喷射点胶针头,喷射点胶机工作之前须先校准喷射针头与工作面距离,即Z轴高度校准。这个需要技术员提前调试好,才能做到事半功倍。

2.喷射阀胶水的粘度的影响

喷射点胶机适合流体喷射,而流体胶水的粘度高低也会影响到点胶的质量。流体胶水粘度大,胶点则小,也会出现拉丝的情况;流体粘度小,则胶点大,会出现胶水/油墨渗染产品的情况。根据流体胶水选择相应的喷射阀也是非常重要的。

3.流体固化曲线对喷射点胶机的影响

盈致对于流体胶水有过深刻的研究,大部分流体胶水都有固化时间和固化温度曲线,喷射点胶机应根据流体固化时间调节点胶速度,使胶水固化后有足够强度。

尽管,喷射点胶机在喷阀和流体上有些要求,但这并不影响喷射点胶机在点胶机市场的地位,毕竟喷射式点胶机的喷涂方式和工艺得到各行业的认可,且非接触喷涂的工艺和精度也比常规点胶机高。
