Automatic dispensing machine equipment is widely used in various major fields, such as semiconductors, electronic components and so on. As it happens, these areas of automatic dispensing machine production process requirements are very high, so how to effectively protect the dispensing accuracy of automatic dispensing machine, generally need to be set from the following three aspects.
Dispensing size and glue viscosity settings, the size of the dispensing amount in general should be half of the product spacing, so not only to ensure that the components have sufficient glue for bonding, there will be no excess glue overflow, so that automatic dispensing machine dispensing speed faster and more accurate. Glue viscosity is large, small glue point, easy to appear drawing phenomenon, glue viscosity is small, glue point is large, may appear glue seepage dyeing products phenomenon, so automatic dispensing machine to choose the appropriate glue viscosity is very important.
Dispensing needle and dispensing pressure settings, automatic dispensing machine needle selection should be based on product size and the diameter of the glue point to choose, usually, automatic dispensing machine dispensing needle size should be half the size of the glue point, dispensing machine needle too General Assembly caused glue overflow, affecting the accuracy of dispensing. and dispensing pressure too general cause glue overflow phenomenon, pressure too small will appear leakage point or dispensing intermittent situation, so can not meet the product requirements of the dispensing process, so that the product pass rate is low, low efficiency.
Dispensing machine needle and face between the interval settings, different automatic dispensing machine used dispensing needle is also different, some needles have a certain degree of stop, some needles do not, so grasp the needle and working face between the dispensing interval is very important, each time in the dispensing work should be done to calibrate the needle and face spacing.
