5 Important things to know about Torsional Robotic Cables

In the robotic industry, high mechanical stress can be a major issue for the independent movement of the robots. Torsional and tensile stresses are the factors that normal cables fail to overcome as robot cables. Robotic arms and components bend millions of times, and standard jacketed cables cannot survive in such applications.

CLOOM Tech can help you with custom cables manufacturing for the robotic industry as per the project requirements. The requirements can vary depending upon the chemical exposure and the temperature of the industrial settings. Here is how torsional robotic cables can solve common robotic cable issues:

1.Correct Torsional Cabling for Industrial Robotics

In order to withstand a million cycles of bending in the industries, robotic cables must have a unique design. Quality and reliability are not the only options that you need to consider. The design of the cables is the factor that decides the quality of the cables. Without optimized and flexible design, these cables are going to collapse soon.

Torsional robotic cables are the advance with optimized and flexible design. Every component, including material, shield construction, and jacketing, can compensate for the changing angles and diameter. Correct cables mean that the cable can handle complicated robotic movements. In the meantime, the quality of the cable should also stay intact to offer a long lifespan. Not only for the power supply but the data transmission too, industrial robots require special data transmission cables. Within the given range, torsional robotic cables offer efficient data transmission.

During the robotic movements, cables have to withstand different types of mechanical stresses too. In industrial robotics, these are the common types of mechanical stress:

Torsion mechanical stress
• Centrifugal force
• Bending

Even with optimized and advanced design, you cannot be 100% sure that the cables are going to last longer. For the quality of the torsional robotic cables at CLOOM Tech, we have torsion test standards where we test cables before delivering to the client.

2.Flexing vs.Twisting of Cables

If you are looking for cables for your robotic industry, make sure than you are clear about the applications. The selection of the right cable highly depends upon the environment where you want to deploy those cables. Industrial teams and technicians must be able to differentiate between the flexing cables and the torsional cables. Flexing cables are suitable for industries where only bending is the main concern. For the operational settings where continued longitudinal twisting is also an important factor along with bending, the torsional robotic cables are the only option. In most of the industrial robots, the robotic arm moves back and forth while bending at different angles.

Most of the torsional robotic cables are available for specific torsion angles and don’t fit into custom projects. If your required angles are not available in the market cables, customizing them is a good choice. While ordering the custom them, make sure that you deliver accurate parameters to the manufacturer.

Most of the engineering teams tend to overlook the need for torsional robotic cables for projects. Not only are different from static cables in terms of design in quality and performance too. The lifespan of the can vary depending upon different situations and the external factors. If you are looking for the robotic cables for the chemical industry, make sure than the protective material can offer the required chemical resistance.

Even if the standard cables are flexible enough for the bending, the internal components like conductors can disintegrate with the movement. In the case of single-component disintegration, the robot will stop working. Everything considered torsional robotic cables are the only power supply option that can integrate with the robotic movements in the industry.

3.Accurate length of Torsional Robotic Cables

For the accurate movement of the robotic cables, the right length of the torsional robotic cables is a fundamental factor. Accurate length means that the cable should not be too long but long enough to offer movement in the required area. If the cable is too short, it will not only restrict the movement of the cable but will also make the connection difficult. For the connection of the cable, you will have to bend the cables many times at different angles. In case the cable length is not according to the requirements, you won’t be able to connect the wires properly.

Although short cable can be a problem in industrial robots, too lengthy wires are also not the solution. Lengthy wires can be hard to manage, too, as you will have to use a lot of wiring harnesses, and that might not be possible as per the robotic movement. For better mobility and optimized cable management, the précised cable length is the only option.

If you don’t get to analyze the accurate length of the industrial robots, you will end up paying more. Lengthy cables are sly going to be more expensive, and you don’t need the extra length. Hence, custom torsional robotic cables have an accurate length as per the project requirements. Most of the industrial units prefer to analyze the working of the robots by using the simulations. Using these kinds of technologies can give you an idea about the actual working of the robot. Once you know the real-time behavior of the robot in the working environment, we can take control from there.

4.Firm But Not Rigid Cables

Flexible torsional robotic cables don’t mean that you need to use low-quality cables to achieve the required flexibility. Securing the cables from external is important, but the jackets must not be rigid. If the cables are too tight, a little exceptional movement from the main course will sabotage the working of the components. Cables must be firm so that other cables don’t get twisted with each other.

Rigid cables are more vulnerable to failure and damage, so the right installation of torsional robotic cables matters a lot. Over clamping of the cables can also restrict the robotic mobility, and for that purpose, custom cable assemblies are available. The installation process can also create many problems, twisting of the cables and the use of too many ties.

If integrators install the cables with too much tightness, it will not leave enough space for the torsion movement. Most of the torsional robotic cables break due to the wrong installation of the cables. Using rigid jackets to secure power supplies is another mistake that can result in project failure.

5.Six-axis Movement of Cables

The days are gone when robots could perform back and forth movements only. In today’s industry, the robotic industry has revolutionized every sector of life with smart, automated robots. These robots can perform different applications in a given course. Robots and automated systems have different applications in different industries where the work environment can be variable. For maximum efficiency, robots can perform a six-axis motion that involves many cycles of banging and twisting.

For industrial robots with a six-axis movement, CLOOM Tech manufactures special designs for torsional robotic cables. These cables can work in a synchronized manner with the other components of the cables. We use special elements in the torsional robotic cables that can bend up to 180%. Custom cables enable the robotic arms to perform free movements from different angles without tensile load.
