A CABLE-MANAGEMENT SYSTEM, A ROTARY JOINT AND A ROBOT

Document Type and Number:

WIPO Patent Application WO/2016/078043

Kind Code:

A1

Abstract:

Disclosed are a cable-management system, a rotary joint and a robot. The system holds a plurality of cables arranged in the rotary joint connected to an articulated arm having a first and a second rotary shaft portions (18, 19). The cables are divided into the outer group of cables (28) and the inner group of cables (29). The system comprises a first cable guide (40), a second cable guide (50) and at least four fixing members (60); the first cable guide has a circular tube-shaped space, and the outer group of cables is partly accommodated between the first cable guide and the second cable guide; the second cable guide has a circular tube-shaped space, and the inner group of cables is partly accommodated between the second cable guide and the first rotary shaft portion (18); the fixing members respectively secure both ends of the outer group of cables or the inner group of cables on and along the first and second rotary shaft portions (18, 19) in a form in which the cables are arranged in parallel with each other, so that remaining portions of the outer group of cables or the inner group of cables are bent and suspended along the first and second rotary shaft portions in a U-shape. Compared with the existing prior arts, the proposed solution is compact and enables a large rotation range.
