What are the factors that affect the dispensing effect of automatic dispensing machines?

With the improvement of factory automation, many manufacturers have started to use automatic dispensing machines to replace inefficient manual dispensing processes. However, many manufacturers have found that the dispensing effect of automatic dispensing machines has not reached the ideal level when using them. What is the reason for this? How should we handle it?

1、 The dispensing amount of the automatic dispensing machine is unreasonable

Generally speaking, when dispensing glue to any product, we should follow a principle that the amount of glue applied by the automatic dispensing machine should not exceed half of the distance between the solder joints. If the amount of glue is exceeded, it will lead to poor dispensing effect.

2、 Control of dispensing pressure

The greater the pressure and amount of glue applied by the automatic dispensing machine, the smaller the dispensing pressure and amount. We should consider factors such as glue characteristics, temperature, environment, and product requirements to set it reasonably! To avoid poor dispensing effect caused by inappropriate pressure parameter settings.

3、 Selection of needle size for automatic dispensing machines

Generally speaking, the diameter of the automatic dispensing machine needle should be about half of the dispensing volume diameter, which is the most suitable needle size. Otherwise, it may cause the dispensing volume of the automatic dispensing machine to be too large or too small, affecting the dispensing effect!

4、 Control of glue temperature

Generally speaking, the storage environment for epoxy resin adhesive should be around 0-5 degrees Celsius, and the usage temperature should be around 23 degrees Celsius. When using adhesive, we should make it better adapted to the surrounding environment to avoid wire drawing problems that may affect the dispensing effect!

5、 The viscosity of glue

The adhesive viscosity of the automatic dispensing machine is high, and the amount of adhesive produced by the dispensing machine is large. The viscosity of the adhesive is small, and the amount of adhesive produced by the dispensing machine is small. Before dispensing, we need to control the viscosity of the adhesive reasonably to avoid affecting normal dispensing work!

6、 Prevent air from entering

The selection of the environment around the automatic dispensing machine is very important. Before the dispensing machine, we need to place it in a dry and closed environment to avoid air entering and causing the dispensing machine to become empty, which will affect the dispensing effect!

When using an automatic dispensing machine for dispensing, manufacturers must try to avoid the factors mentioned above that affect the dispensing effect. To avoid affecting the quality of the product as a result.
