During the design of the spot repair booth in the painting shop,there is a phenomenon of repeated design of a large number of profiles and purchased parts of the same size.It is necessary to make non-standard parts of the same size into standard parts for standardized design.During the implementation process of standardized design,supporting structures such as room columns and beams can be combined with automation equipment to achieve standardized equipment for mechatronics integration.The implementation of standardized design has improved the efficiency of design and prefabrication,ensuring the stability of design quality.
