A wiping device includes a rod, a spraying assembly, a base, and a translation module. The wiping paper is wound around the rod. The spraying assembly comprises a nozzle. The nozzle is arranged above the rod, and the nozzle is arranged towards the wiping paper. The base is used for fixing a workpiece. The translation module is coupled to the rod or the base. When the rod rotates around an axis of the rod, a wiping paper is wound around the rod. The nozzle could spray a cleaning agent to the wiping paper, then, the translation module could drive the rod and the base to move relatively, and the wiping paper wetted by the cleaning agent wipe the workpiece. The cleaning agent could wet the outermost layer of the wiping paper directly, so that the amount of the cleaning agent could be reduced.
