The utility model discloses a vacuum gripping device for display screen production, which comprises two parallel supports and two groups of vacuum gripping devices in sliding connection with the supports, each group of vacuum gripping device forms a triangular working surface for independently adsorbing a display screen by three vacuum chuck seats, the bottom of each vacuum chuck seat is provided with an air suction hole, and the air suction holes are communicated with the vacuum chuck seats. The air suction holes of the three vacuum suction cup bases in each vacuum grabbing device are communicated with one another, and the air suction hole of one vacuum suction cup base is communicated with the air inlet end of a vacuum pump. According to the utility model, the vacuum chucks are divided into two groups for air exhaust and independent adsorption respectively, so that the probability that the adsorption capacities of all the vacuum chucks are reduced or lost at the same time can be effectively reduced in the p
