Since the second threaded rod 206 is threadedly connected to the fixed block 209, the rotation of the second threaded rod 206 will cause the fixed block 209 to move in the horizontal direction, thereby driving the sliding block 208 to slide inside the sliding groove 207.

[0028] Working principle: Start the servo motor 202 to drive the first threaded rod 201 to rotate. Since the first threaded rod 201 is threadedly connected to the connecting block 205, the rotation of the first threaded rod 201 will cause the connecting block 205 to move horizontally, thereby driving the limit block 204 to slide inside the limit groove 203.

The other set of servo motors 202 is started to drive the second threaded rod 206 to rotate. Since the second threaded rod 206 is threadedly connected to the fixed block 209, the rotation of the second threaded rod 206 will cause the fixed block 209 to move horizontally, thereby driving the sliding block 208 to slide inside the sliding groove 207. The cooperation between the sliding groove 207 and the sliding block 208 plays a role in limiting the rotation of the connecting block 205, ensuring that the fixed block 209 can only move in a straight line. The two sets of servo motors 202 cooperate with each other to move the cylinder block 3 to various positions, and then start the pushing cylinder 4 to push the grabbing cylinder 509 to move downward. At the same time, the negative pressure pump 501 on one side of the cylinder 4 is pushed to work, and negative pressure is generated in the suction sleeve 503 through the air pipe 502 below, so that the object is adsorbed through the perforated plate 506. The sealing groove 504 on the inner side of the suction sleeve 503 cooperates with the sealing ring 505 to enhance the sealing effect and prevent negative pressure leakage. When it is necessary to grasp the object more firmly, the grasping cylinder 509 is started to drive the rack block 511 to move upward, and at the same time the spring 510 contracts, and the half gear 512 meshing with it rotates, driving the grab hook 513 to rotate around the rotating shaft 515 and grasp the object. To pick up an object, the rubber block 514 at one end of the grab hook 513 can increase the friction of the grab hook 513, making the grab hook 513 more stable when grabbing an object. When the object is moved to a suitable position, the spring 510 rebounds, and the half gear 512 rotates in the opposite direction, and the object is put down, thus completing the transfer of the object.
