An automatic glue spraying machine for screws, including a screw vibrator, a conveying device, a large asbestos board, a small asbestos board, a high frequency heater, an exhaustion radiating device, two glue sprayers, a glue powder vibrator, a glue powder recovering device, a resilient stopper plate, an arch inclined board and a conveying belt. The screws to be glued are placed in the screw vibrator, whereby the screw vibrator vibrates to upward move the screws along an inner spiral slope face of the screw vibrator into a guide way. The guide way serves to guide and advance the screws to a rotary disk of the conveying device with the screws hung on the peripheral notches thereof. When conveyed, inner retaining arch edges of the large and small asbestos boards serving to keep the screws attached to the periphery of the rotary disk. After the screws are heated by the high frequency heater to a predetermined temperature, the glue powder is evenly sprayed out from the nozzles of the glue sprayers to a predetermined section of the screw and the high temperature of the screw itself instantaneously melt the glue powder to adhere to the screw.
