[0025] Reference Figure 1As shown, the utility model provides an embodiment: an independent manipulator for automatic flipping of workpieces on a production line, comprising a base 1, an independent manipulator body 19 being installed through the base 1, the top of the base 1 being fixedly connected to the independent manipulator body 19, the outer left side of the independent manipulator body 19 being fixedly connected to a grabbing end 2, a fixing cylinder 10 being installed through the grabbing end 2, two fixing rings 3 being fixedly connected to the outside of the base 1, the base 1 being supported by the fixing ring 3, two rotating wheels 5 being slidably connected to the outer wall of the fixing ring 3, the fixing ring 3 being supported by the rotating wheel 5, the outer rotation of the rotating wheel 5 being connected to a pillar 4, the fixed rotating wheel 5 being installed through the pillar 4, the bottom of the two pillars 4 being fixedly connected to a base plate 6, and the pillar 4 being fixed through the base plate 6.

[0026] Reference Figure 2 As shown, the top of the base plate 6 is fixedly connected with a pulley 7, which limits the fixed ring 3 through the pulley 7 to prevent the fixed ring 3 from shifting. The outer wall of the pulley 7 is in contact with the inner wall of the fixed ring 3. The outside of the base 1 is fixedly connected with a rack ring 8. The top of the base plate 6 is fixedly connected with a driving assembly. The driving assembly includes a motor 2 18, which provides power to the gear 1 9 through the motor 2 18. The outer bottom of the motor 2 18 is fixedly connected to the top of the base plate 6. The driving end of the base plate 6 is fixedly connected to the outside of one of the gears 1 9. The top of the base plate 6 is fixedly connected with multiple gears 1 9. The gear 1 9 is engaged with the rack ring 8, so that the gear 1 9 drives the rack ring 8 to move. The gear 1 9 and the rack ring 8 are in meshing connection.

[0027] Reference Figure 3 - Figure 4 As shown, the interior of the grabbing end 2 is fixedly connected to a fixed cylinder 10, and a fixed plate 11 is installed through the fixed cylinder 10. The interior of the fixed cylinder 10 is fixedly connected to the fixed plate 11. The interior of the fixed cylinder 10 is fixedly connected to a motor 12, and the motor 12 drives the gear 2 13 to move. The driving end of the motor 12 is fixedly connected to the gear 2 13. The outer wall of the gear 2 13 is rotatably connected to the interior of the fixed cylinder 10. The interior of the fixed cylinder 10 is rotatably connected to a toothed plate 14, and the meshing connection between the gear 2 13 and the toothed plate 14 makes the gear 2 13 drive the toothed plate 14 to move when it moves.

[0028] Working principle: When the staff needs to adjust the independent manipulator, turn on motor 2 18 to drive gear 1 9 to move, and drive the base 1 to move through the meshing of rack ring 8 and gear 1 9. Under the support of fixed ring 3, the pressure of rack ring 8 is decomposed, and the turntable 5 is installed through the pillar 4. The pulley 7 and the turntable 5 provide support force to the fixed ring 3, and at the same time drive the fixed ring 3 to move, reducing friction, thereby realizing the flipping of the base 1.

Under the restriction of the fixed plate 11, the clamping block 17 moves toward the center, thereby realizing clamping of different workpieces.
