Description

Technical Field

[0001] This utility model relates to a wire harness fixing structure for a robotic arm, belonging to the field of robotic arm technology. Background Technology

[0002] With the rapid development of industrial automation, six-axis robotic arms, with their advantages of high precision and high flexibility, are widely used in many fields such as automobile manufacturing, electronic equipment production, and logistics handling. In practical applications, in order for the robotic arm to achieve diverse functions such as object grasping and precise detection, it is often necessary to assemble various devices, such as sensors and actuators, at its end effector. The communication and power supply between these devices and the control board rely on wiring harnesses, which extend from the end effector of the robotic arm along each joint and finally connect to the control board.

[0003] Currently, the common method for fixing robotic arm wiring harnesses is to use corrugated tubing with braided or tied straps. This method has several drawbacks: First, during the wiring process, due to the softness of the wires and the fact that multiple wires usually need to pass through the corrugated tubing, the wiring operation is extremely cumbersome, requiring each wire to be threaded individually, with increasing difficulty as the process progresses, significantly increasing assembly time and labor costs. Second, when the terminal block or component connected to the end of the wire is larger than the wire diameter, or even exceeds the required corrugated tubing diameter, the wire cannot pass through the tubing. Using a larger diameter corrugated tubing not only occupies more space, resulting in a less compact overall layout of the robotic arm, but also affects the flexibility and smoothness of the robotic arm's movement. Third, when using braided or tied straps to fix the corrugated tubing, if the straps are too loose, the corrugated tubing will shift radially during the robotic arm's movement, potentially interfering with other components and disrupting normal operation. If the straps are too tight, they can easily damage the corrugated tubing, thereby damaging the wiring harness, affecting its lifespan and signal transmission stability. Utility Model Content

[0004] The purpose of this invention is to provide a robotic arm wiring harness fixing structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a robotic arm wire harness fixing structure, including at least two robotic arm fixing rings, one side of each of the at least two robotic arm fixing rings is provided with a wire sleeve for storing the wire, the two sides of the wire sleeve are connected by a zipper, and a connector is provided between the robotic arm fixing rings and the wire sleeve, the position of the wire sleeve is defined by the connector.

[0007] Preferably, the connector includes a cable sleeve fixing seat, which is connected to the robotic arm fixing ring by bolts. Both sides of the cable sleeve fixing seat are fitted with straps, which are connected to the cable sleeve.

[0008] Preferably, the robotic arm fixing ring has a C-shaped structure.

[0009] Preferably, the sleeve fixing base has an M-shaped structure, and the binding straps are respectively located in the notches on the sleeve fixing base.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] By using a cable sleeve, when securing the cable harness, simply unzip the zipper, place the cable harness inside the sleeve, and then zip it up to complete the wrapping of the cable harness. Unlike the corrugated pipe wiring method, which requires threading each cable one by one, this significantly shortens the operation time and improves the efficiency of robotic arm cable harness assembly.

[0012] Because the cable sleeve stores the wire harness through a zipper opening and closing mechanism, as long as the diameter of the cable sleeve is larger than the diameter of the wire harness, even if the terminals or components at both ends of the wire harness are large, they can be easily wrapped inside the cable sleeve for fixation. This effectively solves the problem of wires not being able to be threaded through the existing corrugated pipe wiring method due to the terminals or components being too large.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution:

[0021] like Figure 1 and Figure 2 As shown, a robotic arm wiring harness fixing structure includes at least two robotic arm fixing rings 1. One side of each of the at least two robotic arm fixing rings 1 is provided with a wire sleeve 3 for storing the wire 7. The two sides of the wire sleeve 3 are connected by a zipper 5. A connector is provided between the robotic arm fixing rings 1 and the wire sleeve 3, and the position of the wire sleeve 3 is defined by the connector.

[0022] like Figure 3 As shown, the connector includes a cable sleeve fixing seat 2, which is connected to the robotic arm fixing ring 1 by bolts. Both sides of the cable sleeve fixing seat 2 are fitted with straps 4, which are connected to the cable sleeve 3.

[0023] Furthermore, the robotic arm fixing ring 1 has a C-shaped structure, which allows it to be easily fitted onto the robotic arm. After being locked by fastening components such as bolts, it can fit tightly against the surface of the robotic arm, providing a stable fixing effect.

[0024] Furthermore, the cable sleeve fixing base 2 has an M-shaped structure, and the binding straps 4 are located in the notches on the cable sleeve fixing base 2. On the one hand, this provides a reasonable installation position for the binding straps 4, making them securely installed and not easy to fall off; on the other hand, this special structural design helps to enhance the structural strength of the cable sleeve fixing base 2 itself, ensuring stable support for the cable sleeve 3.

[0025] like Figure 4As shown, the workflow of this embodiment is as follows: Select a robotic arm fixing ring 1 of appropriate size according to the diameter of the robotic arm, and fit the robotic arm fixing ring 1 onto the robotic arm body 8. Secure it to the wire sleeve fixing seat 2 with bolts or other fastening components to ensure that the robotic arm fixing ring 1 is tightly fitted to the robotic arm body 8 and will not move in the radial direction. Then, fit the straps 4 into the notches on both sides of the wire sleeve fixing seat 2, and connect the other end of the straps 4 to the wire sleeve 3. During the connection process, ensure that the straps 4 are firmly connected to ensure that the wire sleeve 3 can be stably suspended from the wire sleeve fixing seat. 2. Next, unzip the zippers 5 on both sides of the cable sleeve 3, put the wire 7 that needs to be fixed into the cable sleeve 3, so that the terminals or components 6 at both ends of the wire 7 are exposed at both ends of the cable sleeve 3. Then zip up the zipper 5 to tightly wrap the wire harness inside the cable sleeve 3. In actual use, when the main body 8 of the robotic arm moves, since the robotic arm fixing ring 1 is firmly fixed to the robotic arm, the cable sleeve 3, which is connected to the robotic arm fixing ring 1 through the cable sleeve fixing seat 2 and the strap 4, can also remain stable and will not shake or shift, thus effectively protecting the internal wire 7 and ensuring its normal operation.
