The invention discloses an airbag laminating device and method for curved glass on a touch screen. The airbag laminating device comprises a support plate and a fixture platform located below the support plate, wherein the fixture platform is used for positioning the curved glass; a main airbag is arranged on one side of the support plate close to the fixture platform; an auxiliary airbag is arranged at a position inside the main airbag corresponding to a bent part of the curved glass; the auxiliary airbag is used for tightly laminating a flexible film to the bent part of the curved glass. The airbag laminating device improves a stress structure of the bent part of the curved glass during lamination by arranging the auxiliary airbag corresponding to the bent part of the curved glass in the main airbag, and increases pressure of the bent part during lamination, so that the flexible film is further laminated to the bent part of the curved glass under compression effect of the auxiliary airbag, thereby eliminating the lamination bubbles of the flexible film and the curved glass, increasing the lamination quality and reducing yield loss.
