What factors are related to the high rate of defective dispensing of automatic dispensers?

With the advancement of factory intelligence, many companies have used intelligent automatic dispensers. The yield and defect rate of automatic dispensers have become a concern of many people. So what factors will cause automatic dispensers Is the defect rate increased?

1. The amount of glue from the automatic dispenser is unreasonable

Generally speaking, when we dispense any product, we should follow a principle that is that the dispensing volume of the automatic dispenser does not exceed half of the distance between the solder joints. If the dispensing volume exceeds this amount, it may cause an increase in the defect rate. !

2. Control of dispensing pressure

The greater the pressure when the automatic glue dispenser dispenses, the greater the amount of glue, the smaller the pressure, the smaller the amount of glue, we should consider the characteristics of glue, temperature, environment and other factors to set it reasonably!

3, automatic dispensing machine needle size selection

Generally speaking, the diameter of the needle of the automatic dispenser should be about half of the diameter of the dispensing volume. This is the most suitable needle size. Otherwise, the dispensing volume of the automatic dispenser may be too large or too small, which will increase product defects. Rate!

4, the glue temperature control

Generally speaking, the storage environment of epoxy resin glue should be about 0~5 degrees Celsius, and the use temperature should be about 23 degrees Celsius. When using glue, we need to make the glue better adapt to the surrounding environment to avoid the use of glue. There is a drawing problem!

5. Viscosity of glue

The automatic glue dispenser has high glue viscosity, the glue output of the glue machine is small, the glue viscosity is small, and the glue output of the glue machine is small. Before the automatic glue machine dispenses, we must reasonably control the glue viscosity to avoid affecting normal Dispensing work!

6. Avoid air ingress

The choice of the surrounding environment of the automatic dispenser is very important. Before the dispenser, we need to place the dispenser in a dry and closed environment to avoid air ingress and emptying of the dispenser, which is also to reduce the dispensing Defective rate!

In summary, it is a normal phenomenon that the defective rate of automatic dispensing machine is high. The high rate of defective dispensing of automatic dispensing machine is related to many factors. We must reasonably control various parameters before the dispensing machine. Precise dispensing, efficient dispensing!
