Cleaning device for optical film lamination device

The utility model relates to a cleaning device for an optical film lamination device. The optical film lamination device is used for laminating an optical film to a glass substrate, and comprises a pair of a laminating roll and a receiving roll and a stripping plate, wherein a carrier film is stripped from the optical film through the stripping plate while the optical film and the glass substrate are clamped between the laminating roll and the receiving roll; the optical film is laminated to the glass substrate in a manner that the laminating rolls apply a pressure to the optical film and the receiving rolls apply a pressure to the glass substrate. The cleaning device comprises a cleaning roll of the laminating roll, wherein the cleaning roll is opposite to the laminating roll and arranged on one side, opposite to one side of the stripping plate. The cleaning roll of the laminating roll of the cleaning device can guarantee cleaning without being in contact with the optical film before lamination; foreign matters such as dust attached to the surfaces of the laminating roll and the receiving roll can be safely and feasibly removed.
