The invention discloses an LED manufacturing system. The LED manufacturing system comprises a workbench, a glue application mechanism, a lamp bead assembling mechanism and a drying mechanism, whereinthe glue application mechanism is matched with an inner core of an LED lamp. An upper connecting portion and a lower connecting portion are arranged at the upper end and the lower end of the inner core correspondingly. The glue application mechanism comprises an upper mold, a locating base, two locating components and a glue application device, wherein the upper mold is arranged on the workbench;the locating base is arranged on the workbench in a manner that the locating base can act forwards and backwards; the two locating components are symmetrically arranged in the left-right direction; and the glue application device is arranged on the upper mold. The locating base is provided with a locating portion, wherein the locating portion is matched with the lower connecting portion. The locating base can rotate relative to the workbench. The locating base is connected with a rotary driving component, wherein the rotary driving component is used for driving the locating base to rotate. Thelamp bead assembling mechanism comprises a driving component, a limiting component, a lamp bead feeding component and a gun assembling material component, wherein the driving component is used for driving the locating base to act forwards and backwards; the limiting component is matched with the upper connecting portion; and the gun assembling material component is matched with the lamp bead feeding component. By means of the LED manufacturing system, lamp beads on the round LED lamp can be assembled automatically; work efficiency is high; and the industrialized production requirement is met.
