Six-degree-of-freedom full-automatic model grabbing manipulator

The invention provides a six-degree-of-freedom full-automatic model grabbing manipulator, and belongs to the field of manipulators. The problem that a traditional manipulator is complex in structure and poor in reliability is solved. The mechanical arm comprises a three-axis rotating assembly, a small arm assembly, a small arm driving assembly, a large arm driving assembly, a tail end single-degree-of-freedom clamping mechanism, a large arm assembly, a vertical lifting mechanism and a controller, the upper end of the three-axis rotating assembly is connected with the lower end of the small arm assembly, and the two ends of the small arm driving assembly are connected with the small arm assembly and the large arm assembly respectively; the small arm driving assembly is used for driving the small arm assembly to swing around the connecting point of the small arm assembly and the large arm assembly, and the three-axis rotating assembly is used for driving the tail end single-freedom-degree clamping mechanism to
