The critical role of extremely thin coaxial beam in the multi-axis motion of industrial robots

With the extensive application of industrial robots in various manufacturing and automation scenarios, multi-axis motion systems have higher requirements for the stability of signal transmission and power supply. The high-speed and frequent joint motion environment makes traditional cables prone to problems such as too small bending radius, rapid fatigue loss, and large signal interference. The extremely thin coaxial cable (Micro Coaxial Cable) with its miniaturization, flexibility, and high-performance characteristics has become an ideal robot wiring solution, providing reliable signal transmission guarantee for intelligent manufacturing.

The importance of flexible design

In the multi-axis linkage process, the wire harness not only needs to transmit high-speed signals but also withstand tens of thousands of bends and twists. If the flexibility is insufficient, it is prone to breakage, poor contact, and even affect the overall operation of the machine. The extremely thin coaxial harness with small diameter and compact structure can achieve large-angle bends within a limited space, effectively extending the service life and improving the overall reliability of the robot system.

The advantages of extremely fine coaxial cable束

High flexibility: The design of micron-level conductors and fine shielding layers allows the cable束 to adapt to continuous swinging and twisting.

High transmission performance: with good impedance control and low attenuation characteristics, meeting the needs of high-speed signal transmission.

Lightweighting: significantly reducing the diameter of the robot arm minimizes load, improving operational efficiency.

High reliability: maintains signal stability under complex multi-axis motion conditions, reducing the risk of failure.

High durability: Some high-end ultra-fine coaxial cable bundles can withstand more than 10 million bending cycles, extending the equipment maintenance cycle.

Four, future development trends

With the improvement of robot intelligence, wire harness design will focus more on the following directions:

Smaller diameter: meets the requirements of robotic end-effector joints and compact structural wiring.

Higher bandwidth: supports high-definition video, AI sensors, and 5G communication modules.

Modular solution: Achieve quick replacement and efficient maintenance through customized harness components.

In a multi-axis motion environment, the ultra-fine coaxial cable bundle, with its excellent flexibility, high-speed transmission capability, and durability, has become a core component for reliable wiring in industrial robots. It not only solves the problems of space constraints and bending fatigue, but also provides a stable signal transmission guarantee for intelligent manufacturing.
