When accuracy matters, a single measurement point often isn’t enough. That’s why fully automated, robot-supported in-line measuring systems are frequently used for quality control in production processes. However, due to the high number of measurement points, the measurement operations are often very time-consuming. To maintain a high cycle rate, the systems usually operate at their performance limits. But the rapid movements of the measuring robots often lead to wear on installation components. Especially the energy supply to the measuring camera in standard corrugated conduit cable packages is subject to heavy wear and must be frequently replaced.

To counter this, users of in-line measuring systems are now relying on the new cable package technology SUMOTEX™. The significantly improved reliability and durability of the solution primarily benefit the users of such systems.

In the Automotive Industry:

In automotive manufacturing, small and uniform gap dimensions are a key quality metric. It’s important for car manufacturers to measure these gap dimensions directly on the production line.

This is where in-line measuring technology (IMT) comes into play. Components are scanned by cameras mounted on measuring robots from all angles. This complex and demanding task requires a seamless interaction between robot control, cameras, and analysis software.

Several companies specialize in providing such fully automated solutions for production lines. For their customers, mainly in the automotive industry, the speed of the inspection process is critical, as it directly affects production capacity and costs. Fast cycle times and 100% inspection require robots operating at maximum speed and flexibility.

High Dynamics Challenge the Energy Supply

However, even the best measuring solution only works if the sensors are reliably powered. This presents a challenge: the power supply to the camera must keep up with the fast, complex movements of the robot arm. These cables need a length buffer to prevent abrasion and are typically enclosed in corrugated tubing with additional protectors. Nevertheless, failures occur due to wear and cable looping, which can snag on parts or edges, causing errors and reducing lifespan.

For IMT manufacturers and operators, a better cable management solution is essential, as every maintenance-related system failure results in production downtime. A better cable routing solution thus adds significant value to the production line.

Intrinsic Resetting Effect – Ideal for Fast Robot Movements

Robot specialists at a major car manufacturer were familiar with Sumcab Robotics from previous projects and were excited to discover SUMOTEX™, a suitable existing product. Unlike traditional systems, SUMOTEX™ routes cables through an air-filled high-tech textile sleeve. The air chambers provide flexible stiffness across the entire cable length, offering multiple advantages:

• The cable adapts to the robot’s movement without sagging.
• No disruptive loops form.
• The cable can be routed close to the robot arm without interfering with movement.
• The durable textile surface greatly reduces abrasion, extending cable life.

This innovation directly addresses the challenges faced by IMT users with camera power supplies.

“With SUMOTEX, Sumcab Robotics has made a technological quantum leap in cable management.”

SUMOTEX™ Reduces Downtime and Maintenance

SUMOTEX™ made its way from the automotive robot test lab to the showroom of an IMT provider. It now plays a key role in their innovative solution. Thanks to the new cable routing, faster robot movement and higher cycle rates are achievable.

Although the increased reliability isn’t easily demonstrated in the showroom, long-term tests at a major automotive plant already show that SUMOTEX™ lasts significantly longer than traditional solutions. This ensures smooth operation and increased production capacity, making investment quickly worthwhile.
