Abstract: A device used in manufacturing for transportation of workpieces of different sizes includes a supporting part, the supporting part including a support plate and parallel and detachable separator plates mounted to the support plate. The support plate includes bottom, first side plate, second side plate, and connecting plate. First and second side plates are parallel and opposing, the connecting plate is connected therebetween. Each separator plate includes a main portion and a protruding first limiting portion. The first limiting portion of one separator plate abuts against the first side plate, and each first limiting portion of other separator plates abuts against the main portion of a neighboring separator plate. The gaps formed between the main portions of neighboring separator plates carry the workpieces being transported.
