A paper roll is transmission-connected between the reel 2 and the reel 3. The paper roll passes through the half-sheet printing position and carries the silicon wafer, thereby transporting the silicon wafer. The paper roll is breathable.

[0028] The unwinding motor 4 controls the unwinding roller 2 on the left side of the printing platform 1 to release the clean paper roll. At the same time, the winding motor 5 controls the winding roller 3 on the right side of the printing platform 1 to retract the dirty paper roll. The two unwinding and rewinding powers are respectively located on both sides of the printing platform 1.

[0029] During the printing process, the front track transfers the double half sheet over, and the winding and unwinding move in opposite directions to bring the double half sheet of silicon wafer to the printing platform 1. Under the effect of air permeability, negative pressure adsorbs the double half sheet on the printing platform 1 for stable printing. Then, the double half sheet is released, and the winding motor 5 and the unwinding motor 4 are activated again, moving forward to control the movement of the paper roll, discharge the double half sheet from the printing platform 1 and move it into the rear track, and at the same time, the unclean paper roll is put into the winding roller 3, and the clean paper roll is kept on the outside, waiting for the next round of double half sheet input.
