An automatic pneumatic gripper applied to a screen printing machine includes a pneumatic cylinder disposed on a top surface of a fixing post and two elastic grippers pivoted on two transverse sides of the pneumatic cylinder respectively. The lower part of two grippers extend downward beyond a bottom surface of the fixing post and projects inwards to form a hook. When a plunger of the pneumatic cylinder protrudes downward and leans against the top surface of the fixing post 30, the two grippers pivot inward, clip and fasten a squeegee/scraper firmly on the fixing post by the hook. When the plunger retracts upward, the pneumatic cylinder falls down relatively falls down so that the two grippers pivot outward, away from each other and the squeegee/scraper is released.
