The accuracy of dispensing is beginning to be displayed in the quantitative accuracy. For example, the error of 0.01 grams of glue is a tiny error when we don't think about the size of the product, which is unavoidable in manual dispensing. If the product with special requirements for dispensing density, the error of 0.01 grams is usually very serious, because the product of dispensing is very small and very precise. After the accurate setting of the pressure and the time of the glue, the quality of the product is much better than that of the hand glue. The most important point is the incandescent lamp without injury to the surface of the finished product, in order to ensure that the yield strength of the need to reduce dispensing, but this does not hinder the normal use of dispensing equipment, for dispensing at a rate of 300mm/s per second, so the dispensing of incandescent lamp can reach a maximum of 1500 hours / huge workload, and can be applied to some the irregular point of incandescent lamp, dispensing, dispensing machine embodies the LED full function. The time of LED glue dispenser entering China is relatively late, but it has strong post advantage because of the domestic glue equipment industry. In addition to the self development of the domestic glue industry, the domestic market also took over a part of the foreign developed countries' enterprises. While the scale of the industry is expanding, it has also gained a certain scale effect. And in this process through each other learning and mutual penetration. It also plays an important role in improving the technology of LED glue dispenser in China.
