1. The dispensing volume of 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 a defect rate to increase. !

 

2. Control of dispensing pressure

 

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

 

Three, the choice of the needle size of the automatic dispenser

 

Generally speaking, the diameter of the needle of the automatic dispenser should be about half of the diameter of the dispensing volume, which is the suitable needle size for Z, otherwise it may cause the automatic dispenser to produce too large or too small a volume of glue, and the added product is bad. Rate!

 

Fourth, the control of glue temperature

 

Generally speaking, the storage environment of epoxy resin glue should be about 0~5 degrees Celsius, and the operating temperature should be about 23 degrees Celsius. When using glue, we should make the glue better get used to the surrounding environment to prevent the glue from being used. There is a drawing problem!

 

Five, the viscosity of the 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 the normal Dispensing work!

 

Six, prevent air from entering

 

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 prevent air from entering. The dispenser appears to be empty, which is also to reduce the dispensing Defect rate!

 

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