1. A curved surface lamination apparatus, comprising:
a profiling jig, comprising: a base and a profiling portion, wherein the profiling portion is configured to support a carrier film and comprises: a bending portion exceeding a border of the base, and a side of the base facing away from the profiling portion has an opening; and
a lower jig, comprising: a first sinking groove, a dovetail edge and a side edge on one side of the first sinking groove away from a central area of the lower jig, wherein part of the base is inserted into the first sinking groove, such that the lower jig encloses a hollow structure with the base at a position of the opening;
wherein an extension direction of the side edge is the same as an extension direction of the first sinking groove, and the side edge is configured to carry the profiling portion;
wherein the dovetail edge comprises: a first dovetail portion and a second dovetail portion, wherein a contact surface between the first dovetail portion and the second dovetail portion is smaller than a surface of the first dovetail portion facing away from the contact surface and is smaller than a surface of the second dovetail portion facing away from the contact surface;
the side edge comprises: a dovetail groove matched with the first dovetail portion, and a defining edge on one side of the dovetail groove away from the central area of the lower jig; and
wherein the bending portion comprises a first bending portion matched with the second dovetail portion, and a second bending portion on one side of the first bending portion away from the base and being in contact with the defining edge.
