Stereoscopic warehouse mechanism

The utility model discloses a stereoscopic warehouse mechanism which comprises at least one set of double-row storage frames, and a guide rail for a material taking and placing robot to walk is arranged between two rows of storage frames. The material taking and placing robot comprises a base, a vertical lifting device arranged on the base and a horizontal transplanting device arranged on the top of the vertical lifting device. A horizontal moving mechanism enabling the vertical lifting mechanism to move in a direction opposite to an inserting moving direction of the horizontal transplanting device is further arranged on the base. The stereoscopic warehouse mechanism has the advantages that due to the horizontal moving mechanism, when the material taking and placing robot carrying cargoes needs to move between two rows of material frames, parts above the vertical lifting device can integrally move to one side where materials do not exist, and the distance between the vertical center line of the robot to a car
