Description

Technical Field

[0001] The utility model relates to the technical field of grinding and polishing, in particular to an industrial robot grinding and polishing workstation. Background Art

[0002] Grinding is a type of surface modification technology. It generally refers to a processing method that uses rough objects (such as sandpaper containing higher hardness particles) to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness.

[0003] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. It is a modification process of the workpiece surface using polishing tools and abrasive particles or other polishing media.

[0004] When grinding and polishing workpieces, manual grinding and polishing is generally used. The manual processing efficiency is low, the labor intensity of the staff is high, and the management cost is high. In addition, due to the different proficiency of the staff, the consistency of the product needs to be improved. Not only that, the amount of dust and noise generated during grinding and polishing is large, and the working environment will cause harm to the human body. Utility Model Content
