1. A bonding method for a flexible panel, comprising:
fixing a protective cover plate into an accommodation space of a bonding jig;
putting a flexible panel with an optical clear adhesive onto a carrier film, wherein a peeling force of the optical clear adhesive in a normal temperature is less than a bondable threshold, the optical clear adhesive is on a surface of the flexible panel; and
controlling a sliding block carrying the carrier film to move in the accommodation space in a set bonding direction, while controlling a driving part to drive the flexible panel on the carrier film to form a shape matched with the protective cover plate, and bonding the flexible panel to the protective cover plate through heating the optical clear adhesive, wherein a peeling force of the heated optical clear adhesive is greater than the bondable threshold;
wherein the protective cover plate comprises a main body portion and two bending portions located at two ends of the main body portion, the main body portion comprises a flat panel region and two ¼ arc bending regions located at two ends of the flat panel region respectively, each bending portion comprises a ¼ arc bending region, and the ¼ arc bending regions of the bending portions are connected with the ¼ arc bending regions of the main body portion to form 180-degree bending between the main body portion and the bending portions; and the bonding jig comprises a first partition and two second partitions located at two ends of the first partition;
the controlling the sliding block carrying the carrier film to move in the accommodation space in the set bonding direction comprises:
controlling the sliding block to move on the first partition of the bonding jig so as to bond the flexible panel to the main body portion of the protective cover plate; and
controlling the sliding block to move from the first partition of the bonding jig to the second partitions of the bonding jig to curve the flexible panel so as to bond the flexible panel to the bending portions of the protective cover plate; and
the controlling the driving part to drive the flexible panel on the carrier film to form the shape matched with the protective cover plate comprises:
controlling the driving part to drive an edge of the flexible panel on the carrier film to form a curved surface whose bending degree is greater than that of each of the bending portions when the sliding block moves from the first partition of the bonding jig to the second partitions of the bonding jig.
