Bulb automatic dispensing machine LED 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, using ball coating on the bottom of LED global automatic dispensing machine, enhance 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. When using the LED bulb automatic dispensing machine to dispensing foam ball, we use the glue is epoxy resin, it is because of the characteristics of the epoxy resin is suitable for dispensing work of this type, it can be extremely strong resistance performance, can protect LED lighting chip will not be outside, still can use a dispensing mode different and to change their performance by adding glue scattering agent to control the direction of the light scattering ability, epoxy resin itself has a superior performance, with anti wet glue solidification, high strength, refraction on the optical projection, high efficiency.
