Although LED dispensing machine has many advantages in dispensing operation, but also not to say that it is perfect. Because the dispensing equipment has just come out soon, the performance also has some defects, such as bubbles in the dispensing process, the dispensing process every time needs to be replaced because of glue, glue barrel outside air into the barrel, if not drained before dispensing it, and will cause the barrel of the glue chemical reaction that causes bubbles and other problems. The bulb is the appearance of the oval shaped, flat ordinary dispensing machine it is very difficult for the fixed dispensing, dispensing machine working plane LED has a plurality of three-dimensional circular groove, can accommodate a plurality of bulbs of glue coating, through the automatic dispensing cycle can ensure the glue in bulb evenly coated, dispensing LED the dispensing machine supports different paths, strict implementation of high precision dispensing path according to the program, the work cycle mode to ensure LED bulb production efficiency, the demand for human resource is low, can improve the production efficiency of manufacturers. 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.
