应用不同像素的CCD和镜头不同放大倍数,以及多种光源的组合,能够完成十分准确的定位精度,同时能够经过编程顺应产品本身的个体误差。
 

 

影响点胶效果的要素通常有点胶量的大小,点胶压力,针头大小,针头与工作面之间的间隔,胶水的粘度,胶水温度,固化温度曲线,胶水中气泡,需求特殊设定的流体等等,下面做下引见,希望可以有所协助。
 

 

首先点胶量的大小通常以为胶点直径的大小应为产品间距的一半,这样就能够保证有充足的胶水来粘结组件又防止胶水过多。点胶量几由时间长短来决议,实践中应依据温度和胶水的特性选择点胶时间。

再者,点胶机针头通常要选取针头内径大小为点胶胶点直径的1/2左右的针头,点胶过程中,应依据产品大小来选取点胶针头。
 

 

还有,针头与工作面之间的间隔,不同的点胶机采用不同的针头,有些针头有一定的止动度,因而需求把握好点胶间隔,以至每次工作开端之前应做针头与工作面间隔的校准,即Z轴高度校准。
