Technical Field
[0001] This utility model relates to the field of robotic arm technology, and in particular to a drag chain routing structure for a robotic arm. Background Technology
[0002] As a high-tech automated production equipment, robotic arms play an important role in modern production. A robotic arm is an automated operating device that can mimic certain movements and functions of a human hand and arm to grasp, move objects, or operate tools according to a fixed program. During the installation of a robotic arm, there are many connecting wires. In order to prevent the connecting wires from affecting the normal operation of the robotic arm, a cable chain structure is needed to limit the installation of the connecting wires.
[0003] Most existing robotic arms have their connecting wires fixed inside cable carriers and cable trays. However, during operation, the robotic arms pull on these connecting wires, causing them to become tangled or messy, which affects the normal operation of the robotic arms. At the same time, the connecting wires are prone to friction between the cable trays or cable carriers, resulting in wear and tear on the connecting wires and affecting the service life of the robotic arms. Utility Model Content
[0004] To address the aforementioned problems, this utility model proposes a cable routing structure for a robotic arm, which more precisely solves the problems of tangled and worn connecting wires during cable routing in existing robotic arms.
[0005] This utility model is achieved through the following technical solution:

A support frame is bolted to the top of the first slider. A limit frame is bolted to the side wall of the support frame. A cable routing assembly is provided on the top of the side wall of the limit frame. The cable routing assembly can guide and limit the connecting wires of the robotic arm.
[0007] Furthermore, a lead screw is rotatably installed inside the limiting frame, and a second slider is slidably installed outside the lead screw. A drive motor is bolted to the side wall of the second slider, and a transmission shaft is installed at the output end of the drive motor.
[0008] Furthermore, the wiring assembly includes a wiring box, which is bolted to the top of the side wall of the limiting frame. A top cover is bolted to the top of the wiring box. Two sets of fixing rods are symmetrically arranged inside the wiring box. Limiting plates are installed on the top of both sets of fixing rods. Limiting plates are slidably sleeved on the outside of the fixing rods.
[0009] Furthermore, both sets of fixed rods are fitted with a return spring, which is located between the limiting piece and the limiting plate. Multiple sets of limiting wheels are evenly distributed on the bottom of the limiting plate.
[0010] Furthermore, the side wall of the cable tray is provided with a cable tray opening, and a limit rod is rotatably installed inside the cable tray opening. The surface of the limit rod is provided with multiple sets of sliding grooves.
[0011] Furthermore, multiple sets of limiting rings are slidably installed on the outside of the limiting rod, and multiple sets of protrusions are provided on the inner wall of the limiting rings.
[0012] Furthermore, the protrusion is correspondingly arranged with the slide groove, and a fixing pin is installed inside the limiting ring.
[0013] Furthermore, a transmission rod is rotatably installed inside the wiring port, and the transmission rod is located below the limiting rod.
[0014] The beneficial effects of this utility model are:
[0015] This utility model proposes a cable routing structure for a robotic arm. With the setting of a limit wheel, transmission rod, limit rod, and limit ring, the connecting wires of the robotic arm can be limited and protected, while facilitating inspection and maintenance by the user. With the setting of a fixed rod, limit plate, return spring, and limit plate, the connecting wires move with the movement of the robotic arm.

[0022] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.
[0023] Please refer to Figures 1-4 This utility model proposes a cable routing structure for a robotic arm, including a base 1. A first slider 2 is slidably mounted on the outside of the base 1. A support frame 3 is bolted to the top of the first slider 2, which can support and stabilize a limiting frame 4. The limiting frame 4 is bolted to the side wall of the support frame 3, which can limit the movement of a second slider 6. A cable routing assembly is provided on the top of the side wall of the limiting frame 4, which can guide and limit the connecting wires of the robotic arm. A lead screw 5 is rotatably mounted inside the limiting frame 4. A second slider 6 is slidably mounted on the outside of rod 5. A drive motor 7 is bolted to the side wall of the second slider 6. A transmission shaft 8 is mounted on the output end of the drive motor 7. The motor drives the first slider 2 to move left and right, which can adjust the left and right position of the entire limiting frame 4. The motor drives the lead screw 5 to rotate, and the rotation of the lead screw 5 drives the second slider 6 to move, which can adjust the height of the transmission shaft 8. The drive motor 7 drives the transmission shaft 8 to rotate, which can assist in the gripping or handling of materials, and thus assist in the conveying or processing of materials, improving efficiency.
[0024] The wiring assembly includes a wiring box 9, which is bolted to the top of the side wall of the limiting frame 4. The wiring box 9 stores the connecting wires of the robot arm, ensuring the overall aesthetics and safety of the equipment. A top cover 10 is bolted to the top of the wiring box 9, facilitating inspection and maintenance of the connecting wires within. Two sets of fixing rods 11 are symmetrically arranged inside the wiring box 9, limiting the movement of the limiting plate 13 and ensuring its vertical movement. Limiting plates 12 are installed on the top of each of the two sets of fixing rods 11, limiting the return spring 14. A sliding sleeve is mounted on the outside of each fixing rod 11. A limit plate 13 is installed, and a return spring 14 is sleeved on the outside of each of the two sets of fixing rods 11. The return spring 14 can reset the limit plate 13 and also fix it in place. The return spring 14 is located between the limit plate 12 and the limit plate 13. Multiple sets of limit wheels 15 are evenly distributed on the bottom of the limit plate 13. The limit wheels 15 can limit and protect the connecting wires of the robot arm. A wiring opening 16 is provided on the side wall of the wiring box 9 for routing the connecting wires. A limit rod 17 is rotatably installed inside the wiring opening 16. Multiple sets of sliding grooves 18 are provided on the surface of the limit rod 17. Multiple sets of limit rings 19 are slidably sleeved on the outside of the limit rod 17. Multiple sets of protrusions 20 are provided on the inner wall of the positioning ring 19. The protrusions 20 are correspondingly arranged with the sliding groove 18. The sliding groove 18 and the protrusions 20 can be used to limit the positioning ring 19. A fixing pin 21 is installed inside the positioning ring 19. The fixing pin 21 and the positioning ring 19 are screwed together to fix the positioning ring 19. A transmission rod 22 is rotatably installed in the cable routing port 16. With the arrangement of the transmission rod 22, the positioning rod 17, and the positioning ring 19, the connecting wire can be limited and protected. The transmission rod 22 is located below the positioning rod 17. The connecting wire passes under the positioning wheel 15 and is located in the groove on the surface of the positioning wheel 15. Then it passes between the transmission rod 22 and the positioning rod 17. The connecting wire is located in the positioning ring 19. Between positions 9, the user can adjust the position of the limiting ring 19 by rotating the fixing pin 21, which facilitates the limiting of connecting wires of different diameters and achieves a good limiting effect on the connecting wires. At the same time, the cylindrical design of the limiting wheel 15, transmission rod 22, and limiting rod 17 can reduce the wear of the connecting wires and extend their service life. When the robot is operating, the robot drives the drag chain to move. The movement of the drag chain can pull the connecting wire. Under the limiting of the transmission rod 22, limiting wheel 15, limiting ring 19, and limiting rod 17, the movement of the connecting wire causes the limiting wheel 15 to move upward. The upward movement of the limiting wheel 15 causes the limiting plate 13 to move upward. The upward movement of the limiting plate 13 causes the return spring 14 to compress. After the robot returns to its original position, the return spring 14 will cause the return spring to return to its original position.The limit wheel 15 resets synchronously with the connecting wire, preventing the connecting wire from becoming tangled or twisted, ensuring the normal operation of the robot, and facilitating inspection and maintenance by the user.
[0025] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
