Process Turning Disc Cable Guide Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable guiding systems in industrial robots, such as those described in WO 2010/052031, expose cable packages to excessive wear due to the use of cable clamps, leading to a shortened service life.
Innovation Solution
A process turning disc with a detachable cable guide featuring sliding surfaces and a cable clamp that supports the cable package in multiple directions, including perpendicular to the axis of rotation, along with a roller to protect the cables and facilitate bending movements, thereby extending the cable guiding system's support and reducing wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a cable clamp is used to constrain the cable package in the passage, then the cable package is prevented from escaping the passage, but the cable package is exposed to extensive wear and the service life is shortened
Solution Approach 1:
A cable guide made of soft, wear-resistant material is introduced as an intermediary between the cable package and the cable clamp. The cable guide extends across the passage opening and provides a gentle guiding surface that reduces direct contact and wear on the cable package, while still maintaining constraint stability through its geometry and interaction with the cable clamp.
2Ease of repair
If the cable guide is made as a detachable component, then the cable guide can be easily replaced and maintained, but the structural complexity of the process turning disc increases
Solution Approach 1:
The cable guide is designed as a separate, detachable component from the process turning disc, allowing it to be independently replaced when worn. This segmentation enables maintenance without disassembling the entire robot tool, improving ease of repair while the simple attachment mechanism minimizes the increase in structural complexity.

AI summary
A process turning disc (10) comprises a first flange (20) configured to support a cable package (60) in a first direction and a second flange (30) configured to support a cable package (60) in a second direction which is opposite to the first direction. A connecting member (100) connected to the first and the second flanges (20, 30) is configured to support a cable package (60) in a third direction which is perpendicular to the first direction. A cable guide (70) is fastened to the process turning disc (10)in a detachable manner and comprises a cable clamp (110) which is configured to support a cable package (60) in a fourth direction which is opposite to the third direction. The cable guide (70) further comprises two sliding surfaces (80) configured to support a cable package (60) in the first and the second directions outside of the cable clamp (110). A bending movement of the cable package (60) is thereby allowed in a plane perpendicular to the axis of rotation of the process turning disc (10).
