Multi-output 3D printing redundant parallel robot

The invention discloses a multi-output 3D printing redundant parallel robot, relates to the field of robots and belongs to the technical field of 3D printing. According to the multi-output 3D printing redundant parallel robot, multiple identical products can be printed at the same time, the rigidity of a platform is improved through redundant driving, the movement stability of the platform is improved, and printing precision is improved. The multi-output 3D printing redundant parallel robot comprises a base assembly, a duplex lead screw movement branched chain assembly, a rhomboidal movement branched chain assembly, a printing spray head assembly, a knuckle bearing connecting rod and a knuckle bearing installation shaft. According to the connection of the multi-output 3D printing redundant parallel robot, a U-shaped sliding block in the base assembly is connected with the printing spray head assembly through the rhomboidal movement branched chain assembly, so that a spherical pair is formed; the duplex lead screw movement branched chain assembly is connected with a printing spray head through the knuckle bearing installation shaft, so that a spherical pair is formed. The sliding block moves linearly along a guide rail so as to drive the rhomboidal movement branched chain assembly to move, a spiral rod of the duplex lead screw movement branched chain assembly moves linearly along the guide rail, and the sprinting spray head assembly can move horizontally in the space through the cooperation between all drives.
