Use Automatic Dispensing Machine Need to Pay Attention to Three Points?

With the rapid development of electronic industry technology and the multi-functional requirements of enterprises for electronic product automation, the previously used perforated components can not meet the demand. The Dispensing Machine developed by desktop Automatic Dispensing Machine equipment manufacturers has solved this problem for many enterprises. Many people don't know how to use the automatic dispensing machine correctly and what to pay attention to when using it. What should we pay attention to when using the automatic dispensing machine.

In practice, the inner diameter of the needle of the full-automatic dispensing machine should be a certain proportion of the diameter of the dispensing point. In the dispensing process, the dispensing needle shall be selected according to the pad size. If there is little difference in pad size, the same type of needle can be selected, but for pads with great difference, different types of needles need to be selected, which can not only ensure the glue spot quality of the automatic dispensing machine, but also improve the production efficiency.

Generally, the epoxy resin glue used in the full-automatic dispensing machine should be kept in the refrigerator. When using, it should be taken out for standby for a period of time in advance, so as to make the glue fully consistent with the working temperature. Moreover, the ambient temperature has a great impact on the viscosity of glue. If the temperature is too low, the glue point will become smaller, resulting in wire drawing. Therefore, the ambient temperature should be controlled. At the same time, the ambient temperature should also be guaranteed to avoid too small glue humidity and drying of glue spots, which will affect the adhesion.

When using the automatic dispensing machine, the appropriate pressure can be selected according to the glue of the same quality and the working environment temperature. Too much back pressure is easy to cause glue overflow and other conditions; However, if the pressure is too small, intermittent dispensing and leakage will occur, resulting in defects. When the ambient temperature is high, the glue viscosity will become smaller and the fluidity will become better. Therefore, it is necessary to reduce the back pressure of the full-automatic dispensing machine in time to ensure the supply of glue, and vice versa.
