The invention discloses a one-key automatic button popping-up method. The method comprises the steps that firstly, equipment is assembled, specifically, a button pushing mechanism and a button conveying pipeline are mounted at the bottom of a button storing pipe, and an adjusting support is mounted at the bottom of the button storing pipe; secondly, buttons are stacked, specifically, an assembledone-key automatic button popping-up device is placed on a working table surface, a vibrating disc is placed beside the button storing pipe, an outlet of the vibrating disc is in butt joint with an opening in the top of the button storing pipe, and the buttons fall into the button storing pipe from the outlet of the vibrating disc in order; thirdly, the buttons are popped up, specifically, a push rod button is pressed, the button on the bottommost layer is pushed out of a button discharging outlet through the push rod button and enters a button horizontal conveying channel, the button falls naturally due to gravity, a reset spring rebounds, and the button pushing mechanism rebounds to a button pushing port; and fourthly, the button is received. According to the one-key automatic button popping-up method, the buttons can be effectively managed and collected, wasting of the buttons is avoided, and work efficiency is improved.
