如何把三防漆涂覆机调试到最佳运行状态?

三防漆涂覆机的最佳工作状态,可以从三防漆涂覆机的针头选择、出胶时间、点胶压力这几方面着手调试。

1.三防漆涂覆机针头的选择

三防漆涂覆机针头内部的直径应该选择和胶点半径一样。在点胶工作中,可根据产品大小来选取合适的点胶针头,不同大小的产品要选用适合的针头。这样可以有三防漆涂覆机进行点胶工作,避免出现胶点有瑕疵问题。

三防漆涂覆机的最小点胶量标准量少0.005毫升,不锈钢的针头最小内径是0.1毫米,针头最小内径0.1毫米。三防漆涂覆机有特制的针头内径可以达到0.02毫米。

注意:点胶针头到线路板的高度和针头内径是最重要的参数,所以选择合适的点胶针头也是有讲究的。

2.三防漆涂覆机出胶时间的设定 

点胶量的设定应该为产品间距的一半,保证有足够的点胶量粘贴组件,也要注意过多的胶水渗出。

三防漆涂覆机的出胶量可以通过点胶机出胶时间来调节的,现实生产中可根据具体情况调节(车间温度、胶水的粘稠度,点胶的速度等)设置点胶量和出胶时间。

3.三防漆涂覆机的压力的设定

三防漆涂覆机出胶量的多少是由三防漆涂覆机控制器把压力提供给胶管和针头的,三防漆涂覆机压力大小决定出胶量和点胶的速度。

压力过强容易出现胶水喷出、胶量过多等问题,以致于影响产品的外观美感;压力太弱则会出现点胶不均匀和漏点胶的现象,从而影响产品质量问题。

现实生产中应根据具体环境设定压力,比如根据(胶水粘性,生产车间的环境,气温高低)等因素来设置合适的压力;再补充一个问题,气温过低会使胶水粘度升高、流动性变差,此时则需要调高压力值,反之亦然。
