Because the silica encapsulated LED dispensing dispensing equipment is one of the common, so some opportunity of dispensing dispensing, silica gel dispenser will also appear, for example in the use of glue dispensing, dispensing needle clogging will appear leak glue, glue glue drop when the point size is not a bad phenomenon, if there is you need to find the right way to solve problems. When the phenomenon of glue blockage occurs, we must first check whether the dispensing needle is clogged. If the operator does not clean the dispensing machine after finishing the dispensing machine, the glue will remain in the dispensing needle, and the probability of transferring and blocking is the greatest. In general, the diameter of the needles is too narrow because of the use of the needles. If the long time of dispensing, the residual gum impurity hole, and no cleaning, the impurities accumulate, resulting in glue blocking phenomenon, solve this problem, the fastest way is to replace or remove the dispensing needle, after dispensing needle cleaning, re installation. If the silica encapsulated LED dispenser for dispensing the occurrence of glue point sizes, or pressure barrel pressure is not stable or lack of glue concentration, to solve this problem first improve dispensing pressure strength, general high pressure stability is stronger, then adjust the glue glue the longer the time, the glue more stable.
