1. A co-axial roller printing equipment for coating a slurry on a substrate, the co-axial roller printing equipment comprising:
a working platform configured to carry the substrate and drive the substrate to move;
a roller configured above the working platform, the roller having a surface and rotating on an axis;
a grinding device configured on the working platform and located on a first side of the roller, the grinding device being configured to contact and grind the surface of the roller;
a cutting device configured on the working platform and located on a second side of the roller, the cutting device being configured to cut the surface of the roller to form a plurality of relief structures; and
a coating structure configured above the working platform and located on a third side of the roller, the coating structure comprising a plurality of holes corresponding to the relief structures, the coating structure being configured to receive the slurry and coat the slurry on the relief structures through the holes;
wherein, the grinding device grinds the surface of the roller and the cutting device cuts the surface of the roller in sequence; wherein, the coating structure coats the slurry on the relief structures, and then the roller prints the slurry on the substrate; wherein, the cutting process, the grinding process, the coating process and the printing process are performed without disassembly of the roller.
