Precision dispensing machine with a plurality of circular groove position, can simultaneously accommodate multiple circular dispensing tool, not only improves the encapsulation rate, but also ensure LED bulb package quality, the use of precision dispensing machine for coating on the bottom, strengthen the bonding strength of bulb to improve service life. It mainly applies glue to the bonding surface of bulb and lamp holder to make bulb lamp achieve the standard fixed effect, and long-term use will not affect the quality of work. It is an important step in the production of bulb. Behind the traditional mode of dispensing equipment greatly solve the production efficiency is slow, a lot of improvement in the dispensing efficiency and dispensing quality compared to the manual, has also been greatly improved in the consumption of material dispensing, precision dispensing machine can complete the most important dispensing operation in some simple geometric pattern, and method of use simple, but compared to the manual dispensing, dispensing machine to produce the adhesive more uniform and the application in the industry, can improve the quality of dispensing.
