The invention discloses a variable-
diameter fruit and vegetable picking end
effector based on a three-fold paper folding structure. The variable-
diameter fruit and vegetable picking end
effector comprises a support, a paper folding grabbing mechanism and a
cutting mechanism. The support is used for being connected with the
tail end of a mechanical arm. The folded paper grabbing mechanism comprises a Mipu paper folding structure and a picking driving mechanism for driving the upper layer or / and the lower layer of the Mipu paper folding structure to unfold or fold; the three-source paper folding structure comprises multiple groups of three-source paper folding units arranged on the connecting frame, the multiple groups of three-source paper folding units are curled along the central axis, and the head-to-
tail adjacent three-source paper folding units are mutually connected to form a cylindrical structure for wrapping
fruits and vegetables to be grabbed; by means of the arrangement, the variable-
diameter fruit and vegetable picking end
effector can achieve lossless grabbing of
fruits and vegetables in the fruit and vegetable harvesting process, has the advantages of being light in structure, high in fruit shape adaptability, soft in grabbing and flexible in operation, can be widely applied to automatic picking scenes of various
fruits and vegetables, and is better in practicability and universality.
