The use of LED precision dispensing machine are small parts of the glue dispensing, not artificial, in the face of these work requirements of the industry, need to configure the dispensing machine parts cost is relatively high, but after the purchase is the enterprise, no longer need to pay the costs, and the use of artificial production, although each payment as long as the cost of LED dispensing 1/10, but after a few months after enough a dispensing fee, then do not pay, dispensing machine can also work, but not artificial. The purchase of screw pump installed to improve dispensing accuracy in LED precision control of the glue dispensing machine, has also been improved, the production of LED lamp does not need rework, it has a lot of experiments using the quality of dispensing machine screw pump is so promotion in the market, especially for precision dispensing machine use for a period of time machinery, used for a long time, there is always a dispensing place of wear, the use of screw pump can reduce the wear of the part.
