When pouring glue into power supply, we must control the size of glue pouring according to the needs of power supply to achieve the purpose of pouring. When pouring power supply, we should pay attention to not less glue and no overflow. Next, the pressure plate pump manufacturers to talk about how to control the size of the filling glue in the power supply filling machine, and improve the quality of the glue.

在讲关于自动灌胶机胶灌的大小的前提下，伙伴们要了解灌胶针头与电路板的距离以及针头内径是重要的参数。压盘泵厂家提醒各位小伙伴，如果针头和基板之间的距离不正确的话，操作人员将永远无法得到正确的灌胶结果。

On the premise of the size of the automatic glue filling machine, partners should understand that the distance between the glue filling needle and the circuit board and the inner diameter of the needle are important parameters. The pressure plate pump manufacturer reminds you that if the distance between the needle and the substrate is not correct, the operator will never get the correct glue filling result.

在其他参数不变的情况下，如果灌胶针越大，胶灌直径就越小，胶灌高度就越高;灌胶针头与电路板的距离越小，胶灌直径就越大，胶灌高度就越低。

With other parameters unchanged, if the larger the glue filling needle is, the smaller the glue filling diameter is and the higher the glue pouring height is; the smaller the distance between the glue filling needle and the circuit board is, the larger the glue pouring diameter is and the lower the glue pouring height is.

胶灌的直径是由针头内径和针头与基板的距离决定的。当针头内径相同时，如果改变针头和基板之间的距离，虽然灌的胶量完全相同，也可能得到不同的胶灌直径和胶灌形状。

The diameter of the glue filling is determined by the inner diameter of the needle and the distance between the needle and the substrate. When the inner diameter of the needle is the same, if the distance between the needle and the substrate is changed, although the amount of glue poured is the same, different diameter and shape of glue pouring may be obtained.

但通过改变胶针的高度而改变胶灌直径也有一定的范围限制。灌胶直径是不可能小于甚等于所使用针头内径的。这是由于胶和针头之间表面张力(f1)与胶和基板之间的表面张力(f1)二者相对作用力所致。

However, there is a certain limit to change the diameter of glue filling by changing the height of glue needle. It is impossible for the glue filling diameter to be less than or equal to the inner diameter of the needle used. This is due to the relative force of the surface tension (F1) between the glue and the needle and the surface tension (F1) between the glue and the substrate.
