A method for preventing sticking together of book pages during page turning of a book file, comprising the following steps: a book file (4) is placed on a tooling platform (5); a page turning manipulator (3) is first driven by a lifting mechanism (7) to descend in a straight line; the page turning manipulator (3) is then driven by a page turning arm (6) to deflect towards a scanned page; the lifting mechanism (7) restarts movement after the page turning manipulator (3) contacts and bonds to a scanned page, and the page turning manipulator (3) is driven by the lifting mechanism (7) to descend along a guide direction of the lifting mechanism (7), at which moment the page bonded to the page turning manipulator (3) bends to form an arch-shaped curved surface, and then the lifting mechanism (7) is locked again; and a rotating motor (2) on the page turning manipulator (3) starts to rotate to drive the page turning manipulator (3) to rotate anticlockwise, thus completing page separation. The method resolves the technical problem wherein pages stick together during page turning of an automatic page turner, thus ensuring that pages remain intact during page separation and that no damage is caused to the pages, while increasing working efficiency of an automatic page turning scanner.
