LED bulbs are also a spherical light emitting semiconductor, which have the same characteristics as ordinary light-emitting semiconductors, which are composed of two PN nodes. The current can be converted to light energy through the semiconductor. Can send out visible light, infrared, ultraviolet. However, the light emitted from LED is not fixed, so we use glue glue to guide LED bulbs to give out the effect of lighting we want, that is to say, LED bulbs will not give out all kinds of light at once. 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 irregular dot, incandescent lamp dispensing, reflects the large LED precision dispensing machine full function. LED large precision dispensing machine has the advantages of simple operation easy programming, according to the staff operating habits can perform automatic dispensing mode can also be used directly for dispensing work of foot switch, the operation in the teaching box can freely set out into the glue and glue delay time, of course, the best link when debugging is ready to effect of normal dispensing. Generally speaking, the stepper motor with strong power is the best driving device, because the working intensity of stepping motor can be applied to heavy repeated bulb dispensing, which ensures the consistency of dispensing work and ensures the normal demand strength of dispensing.
