In an automatic polishing system configured such that under control of a polishing robot and/or a polishing tool by a polishing controller, the polishing tool provides a polishing action on a polishing subject face, a color intensity measurement instrument is provided for measuring an intensity of a specified color in the polishing subject face. Based on the intensity of the specified color measured by this color intensity measurement instrument, the polishing controller controls the polishing robot and/or the polishing tool, so that an amount of polishing work by the polishing tool onto the polishing subject face is adjusted according to the intensity of the specified color.

An air cylinder that changes the posture of an automatic wet sanding unit main body having sandpaper mounted thereon is provided with a guide rod, and an outer circumferential surface of the guide rod has grooves that extend along a shaft centerline of the guide rod and have an arc-shaped cross-section. Balls are interposed between a bottom of each groove and an inner surface of a bush that is provided inside the air cylinder. Thus, it is possible to make two objects compatible with each other: to achieve high-accuracy automatic wet sanding by enhancing the adaptability of the sandpaper to the shape of a painted surface through a reduction of the diameter of the piston rod; and to enhance the durability of the automatic wet sanding apparatus.

In an automatic wet sanding apparatus including a paper peeling unit that has a clamping shaft and a clamping hook, an inclination angle of a leading end surface of the clamping hook is equal to an inclination angle of an outer circumferential surface of a cushion pad at the start of a paper peeling step. Thus, the leading end surface of the clamping hook comes into contact with an outer circumferential end of a disc at the same time as coming into contact with the outer circumferential surface of the cushion pad, so that the cushion pad is less likely to get caught due to deformation of the outer circumferential surface and its peripheral part of the cushion pad. It is therefore possible to appropriately remove the sandpaper from the cushion pad and stably perform the task of removing the sandpaper.

A sanding automation system for removing a surface defect of an exterior component includes a first robot for generating an inspection mark of a certain pattern on an exterior component with uniform pressure through an inspection mark tool to secure visibility of a surface defect, a vision system for analyzing an image of the exterior component photographed through at least one vision sensor and recognizing a surface defect marking position and a surface defect depth level displayed on the exterior component on which the inspection mark is generated, and a second robot for removing the surface defect by sequentially moving a sanding tool to at least one of the surface defect marking positions and performing a sanding operation with the set amount of sanding according to a corresponding surface defect depth level.
