Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of polishing equipment more specifically, it relates to a kind of multi-station automatic polishing device. BACKGROUND

[0002] Polishing is a kind of surface modification technology, generally refers to the rough object (containing higher hardness particle sandpaper etc.) to change the physical properties of material surface by friction, the main purpose is to obtain specific surface roughness.

[0003] For the polishing of large objects, due to the relatively large stress area, the tool is used for machining and polishing, and the calibration control is relatively easy, and the fault tolerance is relatively high. However, for small objects, especially for the polishing of the glass surface of small watches, the edge of the inner side of the glass needs to be polished to form a concave shape. Due to the characteristics of the glass material and the size of the stress area, the loss of polishing tool and the processing force of the polishing tool need to be strictly controlled during processing. If not careful, the glass will be damaged.

[0004] Therefore, when forming a concave shape on the glass surface, the four directions of the four edges of the rectangular glass surface need to be polished separately. The conventional setting is to set a polishing mechanism for each direction. The processed glass is rotated between each polishing mechanism by suction claws to complete the entire polishing process. However, this polishing method is scattered due to the dispersion of the polishing mechanism, which can only rely on manual operation when changing the tool, thereby delaying the processing progress.
