Panel cleaning device and module production system applying same

The invention discloses a panel cleaning device applied to a display module production system. The display module protection system further comprises a panel conveying mechanism; the panel cleaning device is fixed above the panel conveying mechanism; the panel cleaning device comprises a first glue wheel with first viscosity, and a second glue wheel without viscosity; the second glue wheel and the first glue wheel are parallel at intervals; in use, a panel is positioned on the panel conveying mechanism, and moves in a first direction along with the panel conveying mechanism; the first glue wheel and the second glue wheel are contacted with the surface of the panel in succession, wherein the panel has a first width in the first direction; and the distance between the second glue wheel and the second glue wheel is smaller than 1/2 of the first width. When the first glue wheel generates upward adhesion on the panel, the second glue wheel generates downward stripping force on the panel, so that the first glue whe
