[0007] Furthermore, the first mounting plate is an H-shaped structure.

[0008] Furthermore, the second mounting plate is an E-shaped structure.

[0009] Furthermore, guide grooves are provided on multiple sides of the first mounting plate.

[0010] Furthermore, guide blocks are integrally formed on multiple sides of the second mounting plate, and the guide blocks slide in the guide grooves.

[0011] Furthermore, the top end of the robot manipulator is rotatably connected to the connecting head.

[0013] The beneficial effects of the utility model are:

[0014] 1. The bidirectional threaded rod is rotated under the drive of the driving motor, thereby driving the slider to move in the sliding hole, and then driving the second mounting plate to move, so as to adjust the overlapping length between the second mounting plate and the first mounting plate, so as to grab objects in different ranges.

[0015] 2. The installation shaft and the connecting plate are slidably connected and used in conjunction with a buffer spring to provide buffering when the suction cup is adsorbed, thereby avoiding damage to the object.

[0016] 3. By extracting the air in the suction cup from the negative pressure pipe and the shunt pipe under the action of the vacuum pump, the object is adsorbed, making it easier to grab the object, which is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3A packing robot with an adjustable grasping range comprises a connecting head 1, a robot manipulator 14 and a plurality of suction cups 11. A connecting plate 2 is welded at the bottom end of the connecting head 1. A plurality of mounting shafts 3 are slidably plugged at the top of the connecting plate 2. A buffer spring 4 is sleeved on the outer wall of the mounting shaft 3. The mounting shaft 3 is designed to be slidably plugged with the connecting plate 2 and is used in conjunction with the buffer spring 4 to buffer the suction of the suction cup 11, thereby avoiding damage to the items. A first mounting plate 5 is welded at the bottom end of the plurality of mounting shafts 3. A sliding hole 6 is provided on the top of the first mounting plate 5. Two sliders 7 are slidably connected in the hole 6, a second mounting plate 8 is welded to the bottom of the slider 7, a driving motor 10 is fixed to the top of the first mounting plate 5 by bolts, and a bidirectional threaded rod 9 is keyed to the output end of the driving motor 10. The bidirectional threaded rod 9 rotates under the drive of the driving motor 10, thereby driving the slider 7 to move in the sliding hole 6, and then driving the second mounting plate 8 to move, thereby adjusting the overlapping length between the second mounting plate 8 and the first mounting plate 5, so as to grab objects in different ranges, and the bidirectional threaded rod 9 is threadedly plugged into the slider 7.

[0023] The first mounting plate 5 is an H-shaped structure, and the second mounting plate 8 is an E-shaped structure. Guide grooves 12 are provided on multiple sides of the first mounting plate 5, and guide blocks 13 are integrally formed on multiple sides of the second mounting plate 8. The guide blocks 13 slide in the guide grooves 12, thereby guiding the movement of the second mounting plate 8, thereby improving the stability of adjustment of the first mounting plate 5 and the second mounting plate 8. The top of the robot manipulator 14 is rotatably connected to the connecting head 1, and a negative pressure pipe 15 is provided on the top of the robot manipulator 14. A plurality of shunt pipes 16 are plugged into one end of the negative pressure pipe 15, and the other end of the shunt pipe 16 is plugged into the suction cup 11. Under the action of the vacuum pump, the air in the suction cup 11 is sucked away from the negative pressure pipe 15 and the shunt pipe 16, thereby adsorbing the object.

[0024] The working principle of this embodiment is as follows: when in use, first, the bidirectional threaded rod 9 is rotated under the drive of the driving motor 10, thereby driving the slider 7 to move in the sliding hole 6, and then driving the second mounting plate 8 to move, thereby adjusting the overlapping length between the second mounting plate 8 and the first mounting plate 5, so as to grasp objects in different ranges, and then, the connecting head 1 is moved under the drive of the robot manipulator 14, thereby driving the first mounting plate 5 and the second mounting plate 8 to move, thereby making the suction cup 11 contact with the object, and then under the action of the vacuum pump, the air in the suction cup 11 is extracted from the negative pressure pipe 15 and the shunt pipe 16, thereby adsorbing the object.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
