The dispensing glue problem automatic dispensing machine itself is a device to control dispensing quantity and dispensing time, so the dispensing glue problem which affects product quality must be solved before use.

 

For the glue of automatic dispensing machine, there must be no bubbles, because a small amount of gas will lead to many coatings without glue, resulting in empty bombs and unqualified products, so every time the glue soft is replaced in the middle, the joint must be cleared.

The curing degree of glue is also one of the problems of dispensing glue. Generally, manufacturers have given temperature curves. In fact, glue should be cured at the highest possible temperature, so that the glue has sufficient strength after curing.

Viscosity is also a common problem of dispensing glue, which directly affects the quality of automatic dispensing glue, because if the viscosity is large, the glue point will become smaller or even wire drawing, if the viscosity is small, the glue point will become larger, which may lead to pad penetration. In the dispensing process, we should choose reasonable backpressure and speed for glue with different viscosity.

In addition to the influence of glue and external environment, for the automatic dispensing machine itself, dispensing equipment used by enterprises usually uses special pumps to supply dispensing needles, so constant pressure is needed to ensure that enough glue is supplied to special pumps. Pressure control is easily ignored in dispensing problems, if the pressure is too high. It is easy to cause glue overflow and glue overflow. If the pressure is too low, there will be intermittent glue dispensing leakage, which will cause defects. Therefore, pressure should be selected according to the working environment temperature of different glue of the same quality and automatic dispensing machine. High temperature will reduce the glue viscosity and improve its fluidity. In this case, it can pass through. Reduce back pressure to ensure glue supply.
