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. Then what factors will cause automatic dispensers Is the defect rate increased?


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


Which factors are related to the high rate of poor dispensing of automatic dispensers?


1. The amount of glue dispensed by the automatic dispenser is unreasonable


In general, we should follow a principle when dispensing any product, that is, the amount of glue dispensed by the automatic dispenser does not exceed half of the spacing between the solder joints. If this amount is exceeded, it may cause an increase in the defect rate. !


2. Control of dispensing pressure


When the automatic dispenser is dispensing, the greater the pressure and the greater the amount of dispensing, the smaller the dispensing pressure and the smaller the amount of dispensing. We should set the reasonable combination of glue characteristics, temperature, environment and other factors!


3. Selection of needle size of 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 most suitable needle size, otherwise it may cause the dispensing amount of the automatic dispenser to be too large or too small, increasing the defect of the product rate!

4. Control of glue temperature


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


Fifth, the viscosity of the glue


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


6. Avoid air ingress


The selection of the surrounding environment of the automatic dispenser is very important. Before the dispenser, we need to place the dispenser in a dry, closed environment to avoid the entry of air. The phenomenon of emptying the dispenser is also to reduce the dispensing. Bad rate!


In summary, it is a normal phenomenon for the automatic dispenser to have a high rate of defective dispensing. The high rate of the automatic dispenser's poor dispensing is related to many factors. We must reasonably control each parameter before the dispenser. Precise dispensing, efficient dispensing!
