Design on Multi-color Intelligent Egg Sorter

A multi-color intelligent egg sorter was designed.The equipment included mechanical execution system，electronic control system and shell.The cam in mechanical execution system was designed with topology optimization.Weight of cam group was reduced，power of mechanical execution system was calculated，and stepper motor was selected.Circuit board of electronic control system integrated with buttons，LCD screen and single-chip microcomputer was designed，circuit board of multicolored lights was designed，and power supply module was integrated.Egg sorting experiment was carried out on egg sorter.Results showed that there would be no interference between eggs during sorting process.Each egg was weighed accurately，with an accuracy of 0-2 g，and the weighing range was adjustable.Duck eggs and other egg products could be automatically sorted.Rubber claws ensured that broken egg rate of sorted eggs was less than 1‰，which fully met requirements of manufacturer.
