[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Reference Figure 1-Figure 5 , with a protective transfer quick-detachable oblique arm manipulator, including a manipulator arm 1 and a mechanical claw 13, the mechanical claw 13 includes a driving device and a finger claw, the mechanical claw 13 moves downward to grab the workpiece, and then the mechanical claw 13 after grabbing the workpiece rises to the space enclosed inside the fixed plate 5, the bottom of the manipulator arm 1 is fixed with a top plate 7 by bolts, a detachable connecting component is provided between the top plate 7 and the mechanical claw 13, the upper surface of the top plate 7 is fixed with a first cylinder 8 by bolts, one end of the piston rod of the first cylinder 8 passes through the top plate 7 and is fixed to the fixed plate 5 by bolts, one side of the fixed plate 5 is rotatably connected to the winding roller 10, the outer side of the winding roller 10 is fixed and wrapped with a pull rope 4, One end of the winding roller 10 is keyed to a gear 12, and multiple sides of the top plate 7 are fixed with racks 3 by bolts, and the gear 12 is meshed with the rack 3. The bottoms of multiple ends of the fixed plate 5 are rotatably connected to protective plates 6, and the protective plates 6 are fixed to one end of the pull rope 4. The first cylinder 8 is started, and the first cylinder 8 is extended to move the fixed plate 5 downward, so that the gear 12 moves downward along the rack 3 and rotates. At this time, the winding roller 10 rotates to unwind the pull rope 4, and the protective plates 6 rotate downward under the action of their own gravity, so that multiple protective plates 6 can hold the bottom of the fixed plate 5, so that the clamped workpiece is protected to prevent the workpiece from falling off and falling to the ground and causing damage.

[0025] In the present invention, it should be noted that one side of the fixed plate 5 is rotatably connected to a guide roller 11, and the pull rope 4 is passed around the top of the guide roller 11. The guide roller 11 can guide the pull rope 4 so that it moves according to the required trajectory. The upper surface of the top plate 7 is fixed with a second cylinder 9 by bolts. The second cylinder 9 is extended to move the mechanical claw 13 downward to grab the workpiece. A slot 18 is provided at one end of the piston rod of the second cylinder 9. A block 17 is welded on the top of the mechanical claw 13, and the block 17 is located inside the slot 18 and is slidably connected to the slot 18. A slip ring 15 is slidably connected to the outer side of the piston rod of the second cylinder 9. A magnet 16 is fixed to the upper surface of the mechanical claw 13 by bolts, and the slip ring 15 is in contact with the magnet 16. When the mechanical claw 13 needs to be replaced When changing, push the slip ring 15 upward to separate the slip ring 15 from the magnetic block 16. At this time, the slip ring 15 does not block the block 17. Pull out the mechanical claw 13 to move the block 17 out of the slot 18, and then complete the disassembly of the mechanical claw 13 for easy replacement. The upper surface of the top plate 7 is fixed with a telescopic rod 2 by bolts, and the extended end of the telescopic rod 2 passes through the top plate 7 and is fixed to the fixed plate 5. The telescopic rod 2 can guide the fixed plate 5 so that it can move up and down stably. The bottom of multiple ends of the fixed plate 5 is fixed with a baffle 14 by bolts, and the baffle 14 is in contact with the protective plate 6. The baffle 14 can limit the rotation position of the protective plate 6 to prevent the protective plate 6 from rotating excessively and affecting the use effect of the device. The multiple protective plates 6 are in a concave and inclined state.

[0026] Working principle: When in use, the second cylinder 9 extends, causing the mechanical claw 13 to move downward to grab the workpiece, and then the mechanical claw 13 after grabbing the workpiece rises to the space enclosed inside the fixed plate 5, and the first cylinder 8 is started. The first cylinder 8 extends to move the fixed plate 5 downward, thereby causing the gear 12 to move downward along the rack 3 and rotate. At this time, the winding roller 10 rotates to unwind the pull rope 4, and the protective plate 6 rotates downward under the action of its own gravity, so that multiple protective plates 6 can cover the bottom of the fixed plate 5 to protect the clamped workpiece.

[0027] Furthermore, the terms "disposed," "equipped with," "connected," "connected," and "socketed" should be interpreted broadly. For example, they can refer to fixed connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.
