The graphene-based flexible transparent LED display film preparation device according to claim 7, wherein: be provided with second slide rail (212) on advancing frame station (21), be provided with second slide (313) on sliding chassis (31), loading attachment (3) are through second slide (313) slip setting stack on second slide rail (212) on sliding chassis (31), are provided with third slide (272) on blanking station (27), enter into third slide (272) after sliding chassis (31) leave first slide rail (25), downward landing automatic collection.
9. The preparation process of the flexible transparent LED display film preparation device based on graphene, which is applied to the preparation device of the flexible transparent LED display film based on graphene, is characterized in that:
s1, stacking the loading device (3) on a second sliding rail (212) by a mechanical arm or a person, wherein a power device (24) drives a roller (211) to rotate at the moment, so that the loading device (3) at the bottommost end slides forwards into a panel station (22);
s2, when a loading device (3) is arranged below the film frame (26), the film main body (1) is put into the film frame (26) by a manual or mechanical arm, the loading device (3) moves forwards to enter a bending station (23), and the bottommost film main body (1) is driven to advance together when the loading device advances;
s3, after the loading device (3) enters the bending station (23), the film main body (1) is pressed down so as to be communicated with a circuit, so that the film main body (1) displays images, meanwhile, the film main body intermittently moves forwards under the action of the power device (24), and after each movement, the elastic pulling piece (232) is pulled to slide towards the direction of the pressing rod (231) so as to press the loading device (3), so that the film main body (1) is bent, and the film main body is bent once every forward when a picture is displayed;
s4, the loading device (3) forwards enters a blanking station (27), the film main body (1) is left on the film supporting frame (271), and the loading device (3) slides downwards to be automatically collected through the transfer of a mechanical arm.
