The invention discloses a glass sheet feeding device with a prompt device. The glass sheet feeding device with the prompt device comprises an overturning shaft; the upper side of the overturning shaftis connected with one group of overturning arms uniformly and fixedly; a square pipe is arranged on the upper side of each overturning arm; one group of first straight round grooves are formed in theupper side of the square pipe uniformly at intervals; each first straight round groove is in sliding fit connection with a glass suction disk; one of the square pipes is connected with a mounting plate symmetrically and fixedly; a mounting hole is formed in each mounting plate; an auxiliary suction disk is arranged in each mounting hole; each glass suction disk is connected with a vacuum pump through a gas pipe; an electromagnetic valve is arranged on each gas pipe; and the electromagnetic valves are fixed on the lower side of the overturning shaft uniformly. The glass sheet feeding device with the prompt device has the following advantages that air can rush into the suction disks timely, so that the potential safety hazard caused by the fact that the suction disks cannot complete discharging operation when the electromagnetic valves break down can be avoided, and the safety of operators is improved.
