Use the dispensing machine to do the elements of dispensing work

1, curing factors: for the curing of glue, the general manufacturer gives the temperature curve. Generally, it can be cured at room temperature. In practice, it should be cured at a higher temperature as far as possible, so that the adhesive has abundant strength and hardness after curing.

2, in the dispensing process of the dispensing machine, bubbles will affect the quality of the product, so there must be no bubbles before dispensing. If there are bubbles, the dispatcher will produce many defective products, in use, the glue should be drained of air to prevent the dispatcher idling.

3, the vacuum suction valve must be installed on the distributor. Since the vacuum suction function is to prevent the glue leakage in the dispenser when the glue is not dispensed, if this kit is installed, the vacuum suction valve can be reasonably adjusted to further control the two situations of dripping and wire drawing.

4, needle specifications and types: in the dispensing process, the needle specifications will affect the size and accuracy of the dispensing machine. When the air pressure is within a certain scale, the larger the nozzle of the needle, the greater the distribution rate. Therefore, we need to fix the specifications of the glue needle according to the size of the product produced by the glue dispenser, in general, the inner diameter length of the needle is half of the diameter of the glue point, so the effect is very good.

5, the size of the dosage is determined by the duration of the dispensing machine in the dispensing process. In our experience, the longer the time, the bigger the allocation. This can guarantee that there is plenty of glue to glue the parts and avoid wasting resources caused by too much glue.

6, dispensing machine industry commonly used glue epoxy resin, quick sol, silica gel, anaerobic glue, uv glue and so on.

7, the pressure directly affects the supply and outflow speed of glue. The worse the fluidity of the glue, the greater the thickness, the greater the required pressure, so the pressure should be adjusted in accordance with the temperature of the dispensing machine, the size of the dispensing amount and the characteristics of the glue in the production process. The pressure of the dispensing machine is regulated by its internal pressure regulating valve.
