TRANSFERING DEVICE FOR LARGE AREA SUBSTRATE

摘要

The present invention relates to a transfer device for large area substrates, comprising lower rollers arranged in both ends of multiple transfer shafts arranged close to each other in the transfer direction of substrates; lower surface contact rings wound on the outer surface of the lower rollers arranged in the transfer direction of the substrates to transfer the substrates by being in surface contact with the bottom edge of the substrates while being rotated by the rotation of the transfer shafts; upper rollers separated from each other above the lower rollers; and upper surface contact rings wound on the outer surface of the upper rollers arranged in the transfer direction of the substrates to support the substrates while being in surface contact with the top edge of the substrates. In the present invention, each pair of the upper and lower rollers vertically positioned in a section where the substrates are powerfully transferred is arranged in the front and rear sides along the transfer direction of the substrates. A pair of the surface contract rings being in surface contact with the upper and lower part of the substrates transferred by winding the pair of the upper and lower rollers are arranged to prevent pressure from being concentrated on a part of the substrates, thereby preventing damage to the substrates.
