Laminating jig and laminating method

The invention relates to a laminating jig and a laminating method, the laminating jig is used for a laminating process of a non-planar to-be-laminated object, the laminating jig comprises a flexible profiling seat and a flexible supporting seat, the flexible profiling seat is provided with a profiling surface used for supporting the to-be-laminated object, the flexible supporting seat is arranged on one side, deviating from the to-be-laminated object, of the flexible profiling seat, and the flexible supporting seat is used for supporting the to-be-laminated object. A cavity is formed in the flexible supporting seat, and the cavity is constructed to be capable of expanding so that the flexible supporting seat can generate extrusion force towards the to-be-attached object on the flexible profiling seat, and therefore the gap between the flexible profiling seat and the to-be-attached object can be reduced or eliminated. The attaching jig can solve the problem that in the attaching process, the supporting force p
