CLEANING DEVICE FOR SCREEN PRINTING PLATE

PURPOSE:To obtain a cleaning device capable of completely removing soldering paste deposited on the rear face of a metal mask in relation to a cleaning device for a screen printing plate such as a metal mask for solder printing to, for example, surface mounting parts. CONSTITUTION:A cleaning roller 8 mounted on a metal mask cleaning device has a sectionally circular shape at a right angle to its center axis and is formed into a shape in which the diameter of the cleaning roller in the sectional shape gradually decreases from the central part of said roller toward both ends thereof. When this cleaning roller 8 is brought into contact with the rear face of a metal mask 1 under pressure, the metal mask 1 warps along the shape of the cleaning roller 8, whereby the metal mask 1 and the cleaning roller 8 are closely contacted with each other. Under such a state, the cleaning roller 8 is moved to wipe off soldering paste deposited on the rear facet of the metal mask 1.
