Description

Technical Field

[0001] The present invention relates to the field of cable processing, and in particular to a robotic arm for processing power cables and a method of using the robotic arm. Background Art

[0002] During cable production, the finished cable needs to be wound up, wrapped around the inner cavity of the reel, and then moved and transported to a transport vehicle. Due to the large weight and volume of the wound cable itself, a robotic arm device is usually used to move the finished cable to facilitate loading and unloading of the cable.

[0003] When a common robotic arm device moves a cable, it inserts one end of the robotic arm into the inner cavity of the cable reel, and then uses the rise of the robotic arm to lift the cable, and the robotic arm drives the cable to move. However, a common robotic arm inserts one end into the inner cavity of the reel. Since one end of the robotic arm has poor fixation on the reel, it is not convenient to fix the cable. When the robotic arm drives the cable to rotate, it is easy to cause the cable to shake, reducing the stability of cable grabbing. Summary of the Invention

[0014] The present invention also provides a method for using a power cable processing robot arm, comprising the following specific steps:

[0015] Step 1: First, the operation of the hydraulic pump drives the main body of the robotic arm to bend and move, so that the bottom of the robotic arm drives the connecting block and the movable rod to be inserted into the inner cavity of the wound cable, and then the operation of the hydraulic cylinder is used to push the movable block to move toward the front. The teeth on both sides of the movable block are engaged with the two gears. As the movable block moves, the two gears are driven to rotate together, so that the two movable rods rotate around the fixed axis on both sides. The outer wall of the extrusion block at one end of the two movable rods is squeezed with the inner wall of the cable to grab the cable;

[0016] Step 2: Then, the outer wall of the extrusion block is squeezed against the inner wall of the cable, and the extrusion block rotates around the connecting shaft. The fixed block and one end of the connecting rod rotate together with the top of the connecting shaft, pulling the other end of the connecting rod to slide in the inner cavity of the sleeve. The connecting rod and one end of the sleeve rotate around the fixed column 1 and the fixed column 2 respectively. The other end of the connecting rod drives the clamping block to slide along the inner cavity of the slot. The clamping block squeezes and deforms the compression spring, and uses the elastic action of the compression spring to push the connecting rod back to the initial position, driving the connecting rod and the sleeve to rotate, thereby ensuring the stability of the extrusion block.

[0017] Step 3: Then, the stepper motor drives gear three to rotate, and the meshing action of gear three and gear two causes gear two and the rotating shaft to rotate together, driving the main body of the robotic arm to rotate around the rotating shaft. The cable grabbed by the bottom of the robotic arm body rotates to the back position, and the cable is unloaded to complete the material removal of the wound cable.

[0018] Technical effects and advantages of the present invention:

[0019] (1) The present invention utilizes a configuration in which a movable block, latching teeth, gear 1, movable rod and extrusion block are matched with each other. Through the operation of the hydraulic cylinder, the movable block is pushed to move toward the front. The latching teeth on both sides of the movable block are meshed and connected with the two gears 1. As the movable block moves, the two gears 1 are driven to rotate together, so that the two movable rods expand outward. The outer wall of the extrusion block at one end of the two movable rods is squeezed with the inner wall of the cable. The two ends of the movable rod squeeze and fix the cable. The main body of the mechanical arm is used to grab the cable, ensuring stable grabbing of the cable.

[0020] (2) The present invention utilizes an arrangement in which an extrusion block, a connecting shaft, a connecting rod, a sleeve, a clamping block, and a compression spring are matched. The outer wall of the extrusion block is squeezed against the inner wall of the cable, and the extrusion block rotates around the connecting shaft. The top of the connecting shaft drives one end of the connecting rod to rotate together, driving the clamping block to squeeze and deform the compression spring. The elastic action of the compression spring is used to push the connecting rod and the connecting shaft to rotate, thereby positioning the connecting shaft and the extrusion block and ensuring the stability of the extrusion block.

[0021] (3) The present invention utilizes a configuration in which a rotating shaft, gear two, and gear three cooperate with each other, and drives gear three to rotate through the operation of a stepper motor. The meshing action of gear three and gear two is utilized to drive the rotating shaft and the main body of the robotic arm to rotate 180 degrees, so that the main body of the robotic arm can pick up and release the cable, and the stepper motor drives the main body of the robotic arm to perform a 180-degree reciprocating motion.

[0032] The material-retrieving mechanism 5 includes a mounting block 51, which is used to install a hydraulic cylinder 53. A mounting shaft 52 is fixedly inserted and connected to the mounting block 51.

Through the operation of the hydraulic cylinder 53, the piston rod 54 and the movable block 57 are driven to move together;

[0033] A fixing ring 55 is fixedly inserted and connected on the outer wall of the hydraulic cylinder 53. The fixing ring 55 is used to connect the hydraulic cylinder 53 and the connecting block 56. Both ends of the mounting shaft 52 are rotatably inserted and connected with the connecting block 56. The connecting block 56 rotates around the mounting shaft 52. The connecting block 56 is used to install the gear 1 510 and the movable rod 512. The inner side wall of one end of the connecting block 56 is fixedly connected to one side of the outer wall of the fixing ring 55. One end of the piston rod 54 is fixedly connected to a movable block 57. The piston rod 54 drives the movable block 57 to move between the two connecting blocks 56. The movable block 57 is arranged between the two connecting blocks 56. A plurality of latch teeth 58 are equidistantly arranged on both sides of the movable block 57. The latch teeth 58 on both sides of the movable block 57 are meshed and connected with the gear 1 510.

[0034] The gear 510 is rotated in the inner cavity of the mounting groove 59, and one side of the gear 510 is meshed with a plurality of teeth 58. The movable block 57 moves so that the teeth 58 on both sides mesh with the two gears 510 and rotate. The middle part of the gear 510 is fixedly connected with a fixed shaft 511. The two ends of the fixed shaft 511 are respectively connected with the top and bottom of the inner wall of the mounting groove 59 for rotation. The gear 510 is rotatably connected to one end of the connecting block 56 through the fixed shaft 511. The gear 510 rotates around the fixed shaft 511. A movable rod 512 is fixedly connected between the two ends of the fixed shaft 511. One end of the movable rod 512 is U-shaped. As the fixed shaft 511 and the gear 510 rotate together, the two movable rods 512 rotate in opposite directions.

[0035] The movable rod 512 is provided with a movable groove at one end, and the movable groove is used to install an extrusion block 513. An extrusion block 513 is provided in the inner cavity of the movable groove. One side of the extrusion block 513 is arranged in an arc shape, and is used to fit and extrude the inner wall of the cable. A connecting shaft 514 is fixedly inserted and connected on one side of the extrusion block 513. The extrusion block 513 is rotatably connected to one end of the movable rod 512 through the connecting shaft 514, so that the extrusion block 513 rotates around the connecting shaft 514. The position of the extrusion block 513 is adjusted to ensure that the outer wall of the extrusion block 513 is in stable contact with the inner wall of the cable. The two ends of the connecting shaft 514 are rotatably inserted and connected with the top and bottom of the inner wall of the movable groove respectively. A plurality of protrusions are fixedly connected to the outer wall of the other side of the extrusion block 513 at equal distances. One side of the extrusion block 513 contacts the inner wall of the cable through the protrusions, thereby increasing friction resistance and ensuring that the extrusion block 513 extrudes the cable stably.

[0036] The positioning mechanism 6 includes a fixed block 61, the front side of the fixed block 61 is fixedly connected to the back side of the outer wall of the top of the connecting shaft 514, the fixed block 61 is used to install a fixed column 62, which rotates with the connecting shaft 514, and one end of the fixed block 61 is arranged in an arc shape. The upper surface of the fixed block 61 is fixedly connected to a fixed column 62, and the fixed column 62 rotates with the fixed block 61 for installing a movable ring 63. A movable ring 63 is rotatably inserted and connected on the fixed column 62, and a connecting rod 64 is fixedly connected to the outer wall of the movable ring 63. One end of the connecting rod 64 is rotatably connected to the fixed column 62 through the movable ring 63, and one end of the connecting rod 64 rotates around the fixed column 62, so that the connecting rod 64 rotates with the connecting shaft 514, and one end of the connecting rod 64 is slidably inserted and connected with a sleeve 65, which is used to install the connecting rod 64, and the other end of the connecting rod 64 slides in the inner cavity of the sleeve 65;

[0037] One end of the sleeve 65 is fixedly connected to a movable ring 2 66, and a fixed column 2 67 is rotatably inserted in the inner cavity of the movable ring 2 66. One end of the sleeve 65 is rotatably connected to the fixed column 2 67 through the movable ring 2 66, so that the sleeve 65 rotates together with the connecting rod 64, and the bottom end of the fixed column 2 67 is fixedly connected to the upper surface of one end of the movable rod 512. A compression spring 68 is provided in the inner cavity of the sleeve 65, and the compression spring 68 is provided on one side of the block 610. A slot 69 is provided on the top of the sleeve 65, and the slot 69 is used to install the block 610. The block 610 is slidably inserted in the inner cavity of the slot 69. The block 610 moves together with the other end of the connecting rod 64 and slides along the inner cavity of the slot 69 to prevent the connecting rod 64 from being separated from the sleeve 65, and the block 610 squeezes the compression spring 68.

[0038] The top of the fixed column 62 is fixedly connected with a limiting ring 611, which is arranged above the movable ring 63. The limiting ring 611 is used to limit one end of the connecting rod 64 to prevent the connecting rod 64 from being separated from the fixed column 62, thereby ensuring the stability of the connecting rod 64 and the sleeve 65. The compression spring 68 is movably connected to one end of the connecting rod 64, and the bottom end of the block 610 is fixedly connected to the outer wall of one end of the connecting rod 64. When the movable rod 512 rotates and expands around the connecting shaft 514, the outer wall of the extrusion block 513 is in contact with the cable. The inner walls are squeezed, causing the extrusion block 513 to rotate around the connecting shaft 514. The top of the connecting shaft 514 drives one end of the connecting rod 64 to rotate together, and the other end of the connecting rod 64 slides toward the outside of the sleeve 65, driving the clamping block 610 to squeeze and deform the compression spring 68. The elastic action of the compression spring 68 pushes the connecting rod 64 and the connecting shaft 514 to rotate, positioning the connecting shaft 514 and the extrusion block 513, ensuring that the extrusion block 513 and the movable rod 512 rotate in parallel, thereby ensuring the stability of the extrusion block 513.

A gear 3 9 is provided on one side of the gear 2 8, and the gear 3 9 is meshed with the gear 2 8. The middle part of the gear 3 9 is connected to the output end of the stepper motor 2 for transmission. The operation of the stepper motor 2 drives the gear 3 9 to rotate, and the meshing action of the gear 3 9 and the gear 2 8 is used to drive the rotating shaft 7 and the robot arm body 4 to rotate one hundred and eighty degrees, so that the robot arm body 4 can pick up and discharge the cable, and the stepper motor 2 drives the robot arm body 4 to reciprocate one hundred and eighty degrees.

[0040] Method of use of the present invention:

[0041] First, the operation of the hydraulic pump 3 drives the robot arm body 4 to bend and move, so that the bottom of the robot arm body 4 drives the connecting block 56 and the movable rod 512 to be inserted into the inner cavity of the wound cable, and then the operation of the hydraulic cylinder 53 is used to push the movable block 57 to move toward the front. The latching teeth 58 on both sides of the movable block 57 are engaged with the two gears 510. As the movable block 57 moves, the two gears 510 are driven to rotate together, so that the two movable rods 512 rotate to both sides around the fixed axis 511. The outer wall of the extrusion block 513 at one end of the two movable rods 512 is squeezed against the inner wall of the cable to grab the cable;

[0042] Then, the outer wall of the extrusion block 513 is squeezed against the inner wall of the cable, and the extrusion block 513 rotates around the connecting shaft 514. The fixed block 61 and one end of the connecting rod 64 rotate together with the top of the connecting shaft 514, pulling the other end of the connecting rod 64 to slide in the inner cavity of the sleeve 65. One end of the connecting rod 64 and the sleeve 65 rotate around the fixing column 1 62 and the fixing column 2 67 respectively. The other end of the connecting rod 64 drives the clamping block 610 to slide along the inner cavity of the clamping groove 69. The clamping block 610 squeezes and deforms the compression spring 68, and uses the elastic effect of the compression spring 68 to push the connecting rod 64 back to the initial position, driving the connecting rod 64 and the sleeve 65 to rotate, thereby ensuring the stability of the extrusion block 513.

[0043] Next, the stepper motor 2 is operated to drive gear three 9 to rotate, and the meshing action of gear three 9 and gear two 8 causes gear two 8 and the rotating shaft 7 to rotate together, driving the robot arm body 4 to rotate around the rotating shaft 7. The cable grabbed by the bottom of the robot arm body 4 is rotated to the back position, and the cable is unloaded, completing the material removal of the wound cable.

As the movable block (57) moves, the two gears (510) are driven to rotate together, so that the two movable rods (512) rotate to both sides around the fixed axis (511), and the outer wall of the extrusion block (513) at one end of the two movable rods (512) is squeezed with the inner wall of the cable to grab the cable; Step 2: Then, the outer wall of the extrusion block (513) is squeezed against the inner wall of the cable, and the extrusion block (513) rotates around the connecting shaft (514). The fixed block (61) and one end of the connecting rod (64) rotate together with the top of the connecting shaft (514), pulling the other end of the connecting rod (64) to slide in the inner cavity of the sleeve (65). One end of the connecting rod (64) and the sleeve (65) rotate around the fixed column one (62) and the fixed column two (67) respectively. The other end of the connecting rod (64) drives the clamping block (610) to slide along the inner cavity of the card slot (69). The clamping block (610) squeezes and deforms the compression spring (68), and uses the elastic action of the compression spring (68) to push the connecting rod (64) back to the initial position, driving the connecting rod (64) and the sleeve (65) to rotate, thereby ensuring the stability of the extrusion block (513); Step 3: Then, the stepper motor (2) is operated to drive the gear 3 (9) to rotate, and the meshing action of the gear 3 (9) and the gear 2 (8) is utilized to make the gear 2 (8) and the rotating shaft (7) rotate together, driving the robot arm body (1) to rotate around the rotating shaft (7), and the cable grasped at the bottom of the robot arm body (1) is rotated to the back position, and the cable is unloaded, thereby completing the material collection of the wound cable.
