1. A laminating device, comprising:
a plate, which is bendable, has a resilience characteristic, and is configured for bearing a flexible substrate;
a supporting base platform, for supporting the plate and driving the plate and the flexible substrate on the plate to move;
a bending assembly, for applying stress so as to drive the plate and the flexible substrate on the plate to be bent towards a side of the plate facing away from the flexible substrate, and for releasing stress so as to allow the plate and the flexible substrate to rebound; and
a fixing fixture, for fixing a protective cover plate, wherein the protective cover plate is for being laminated to the flexible substrate; a shape of the fixing fixture is same as or similar to a shape of the protective cover plate; the fixing fixture is bent to form an accommodating space; and the protective cover plate is fixed in the accommodating space;
wherein the bending assembly comprises:
a bearing membrane, configured to be laminated on a surface of a side of the flexible substrate facing the plate, to be disposed on the plate together with the flexible substrate and to drive the flexible substrate and the plate to be bent; and
a drive component, configured to be used in cooperation with the bearing membrane, and to drive the bearing membrane to be bent by stretching the bearing membrane.
