3D-LED alignment laminating method and alignment laminating machine

The invention discloses a 3D-LED alignment laminating method and an alignment laminating machine, relates to the technical field of stereoscopic display, and aims to improve the alignment precision of a 3D film and an LED module to further provide better experience for a user. The method comprises the following steps that 1, after surface glue spraying treatment is conducted on the LED module, the LED module and the 3D film are subjected to pre-pressing laminating; 2, at least one set of phase difference plates are arranged above the 3D film, so that an image, formed by a light-proof array and a light-transmitting array which are mutually staggered, of the 3D film passing through the phase difference plates can be recognized, and the LED module and the 3D film are subjected to alignment adjustment according to the image, wherein during alignment adjustment, two adjacent LED beads in the LED module need to be aligned with the light-proof array and the light-transmitting array in the 3D film respectively; and 3
