Laminating device and laminating method

The application discloses a laminating device and a laminating method. The laminating device is used for attaching a flexible screen body to a curved surface cover plate and comprises a profiling padand a stress adjusting assembly; the profiling pad comprises a first surface and a second surface which are arranged back to back; the first surface is used for bearing the flexible screen body; and the profiling pad and the surface of the side, facing the flexible screen body, of the curved surface cover plate are conformal; and the stress adjusting assembly is used for being arranged on one sideof the second surface of the profiling pad, being attached to the profiling pad and applying pressure to one side of the second surface of the profiling pad, so that the flexible screen body is subjected to uniform attaching stress in the attaching process of the flexible screen body and the curved surface cover plate. By means of the mode, the attaching pressure borne by the flexible screen bodyin the area with the large
