The invention discloses a semi-automatic mylar and rubber dome laminating device. The laminating device comprises a support, a lamination support unit, a lamination driver and a central controller; apair of laminating fixed shoe plates are fixed in the upper and lower surfaces of a central shoe plate; a lamination driving support plate is arranged on the laminating fixed shoe plates in an elasticelevation manner; the end surfaces, far from each other, of the laminating fixed shoe plates are provided with mylar attracting seats; the end surface, close to each other, of the laminating fixed shoe plates are provided with rubber dome attracting seats; the lamination driver comprises a lamination driving top plate; the lamination driving top plate is arranged below the lamination support unit; the central controller is arranged on the support; and a driving component of the lamination support unit and a driving component of the lamination driving top plate are connected with the central controller. The condition of inaccurate mylar and dome lamination due to insufficient rotation of the lamination support unit can be avoided, and the mylar and rubber dome laminating quality is ensured.
