Desktop LED to realize the function of repeated circular dispensing dispensing through programming, one-way execution can dispensing of multiple light bulbs, bulb lamp first position, and then enter the glue volume dispensing time working parameters, easy operation, for a single bulb after dispensing the rotating disc will automatically rotate to second objects dispensing, dispensing work cycle completed more than a light bulb. The glue control effect of LED bulb tube dispensing is very good. During the practical application, there will be no problems such as wire drawing and glue leakage. It strengthens the conversion rate of glue and improves the working quality of bulb. Because the bulb appearance is elliptical, ordinary dispensing technology is difficult to carry out fixed dispensing, working plane circular LED dispensing desktop has a plurality of three-dimensional circular slot, can accommodate a plurality of bulbs of glue coating, through the automatic dispensing cycle can ensure the glue evenly in the bulb is coated on the dispensing work desktop circular LED dispenser support different path, 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.
