triflex energy chains in autonomous repair cell at SEAT

For maximum freedom of movement with simultaneous cable protection

The Spanish company Procon Systems specialises in automated systems for production lines, especially in automotive production. Procon Systems has developed an automatic repair cell for the SEAT paint shop. This recognises and repairs defects in the paintwork of the car bodies independently. The entire process is autonomous.

Profile

What was needed: triflex energy chains, linear retraction system, swivel bracket
Requirements: The energy supply must be flexible and still protect the cable from sagging
Industry: Automotive sector
Success for the customer: Long service life, as the cable package is not under tension

Requirement, challenge and solution for Procon Systems

Requirement

Procon Systems needed an automated repair cell capable of inspecting and repairing paint defects across the entire vehicle body. The system had to supply power, data, compressed air and polishing media to multiple robot axes while maintaining reliable movement and protecting cables during continuous operation.

Challenge

The biggest challenge was ensuring that damage on all areas of the vehicle body could be accurately detected and repaired by the robots. The cable management system also had to cope with complex multi-axis robot movements. A conventional cable package suspended from pulleys was not suitable, as the constant tension would increase the risk of cable wear and failure.

Solution

The engineers chose the igus triflex energy chain system due to its flexibility, manoeuvrability and cable protection. For the main energy supply, the RSEL system provided a compact, cost-effective solution for routing hoses, air lines, and camera control cables on axis 6. Different chain systems were then used to optimise performance across the robot.

Axes 1-3: The lightweight and cost-effective TRL multi-axis energy chain was selected, offering simple installation and sufficient protection for the less demanding movements.
Axes 3-6: The more robust TRE.100.145.0 energy chain was used to accommodate the larger number of cables and hoses, with side openings that simplify filling and maintenance.

To provide the required freedom of movement, a 270° swivel bracket was incorporated, delivering a reliable and cost-effective solution for the robot's extensive range of motion.
