The invention discloses an intelligent storage tray turnover system, including a control mechanism, a turnover mechanism, a transport mechanism, a feeding mechanism and a positioning mechanism. The method includes the following steps: Step S1, the transport mechanism drives the turnover mechanism to enter the positioning mechanism; Step S2, transport The mechanism leaves; step S3, the turnover mechanism rises; step; S4, the turnover mechanism performs centering and positioning; step S5, discharges; step S6, the transport mechanism enters the positioning mechanism, and connects the turnover mechanism; step S7, the turnover mechanism descends; step S8, the transportation mechanism drives the turnover mechanism to leave the positioning mechanism; Step S9, returns to step S1, and executes again. The invention achieves fully automatic turnover tray and cycle operation, realizes unmanned and precise transportation in the workshop, increases the transport volume of trays, significantly improves production efficiency, reduces production costs, and reduces labor intensity of operators, meeting the requirements of The demand of Industry 4.0 promotes the optimization and upgrading of industrial structure and has good market promotion value.
