The invention relates to the technical field of LED lamp assembly, and particularly discloses a full-automatic LED bulb production assembly line. The full-automatic LED bulb production assembly line comprises an automatic stem production device for producing electronic elements with drives, an automatic stem welding device, a seal exhaust device, an automatic lamp holder assembling device and an automatic optometry device, wherein the automatic stem production device automatically assembles and welds a glass horn pipe, an exhaust pipe, a first conductive wire with a drive chip and a resistor,and a second conductive wire into a stem; the automatic stem welding device welds a lamp filament to the stem to form a lampwick; the seal exhaust device puts a lamp shell to the lampwick in a sleeving mode; the automatic lamp holder assembling device assembles a lamp holder to a bulb body to form an LED lamp; and the automatic optometry device lightens the LED lamp for testing aging. Automatic production of the LED lamp is achieved, the manual production cost is reduced to the greatest extent, the LED lamp is produced with high-quality rapidly and efficiently, the full-automatic production process replaces high cost of the manual mode, uncertainty of the quality is reduced, full-time-frame production can be achieved, and the production efficiency and quality are improved.
