The invention discloses a vacuum suction cup device for an insulating glass inflation line, which relates to the field of insulating glass production devices. Aiming at the problem that the existing insulating glass inflation operation cannot be produced online, the following solution is proposed, which includes a frame, a lifting push-pull structure and a gripper According to the structure, the frame includes a top plate, a bracket, a fixed foot plate and a horizontal plate, the lifting push-pull structure includes a wire rail, a first sliding table, a first air cylinder, a screw rod and a motor, and the grabbing structure includes a second sliding table, second cylinder, vacuum plate and suction cup, the top plate and the horizontal plate are both horizontal, and the bracket is vertical, the brackets are located at the bottom end of the top plate and the four corners are symmetrically distributed, and the horizontal plate is located in between the four sets of brackets. The invention has a novel structure, the device realizes the continuous flow operation of inflating the insulating glass, meets the requirements of modern automatic production, improves the production efficiency of the inflating production of the insulating glass plate, and effectively solves the problem that the inflating operation of the insulating glass cannot be produced online.
