The invention discloses a multistage linear telescopic unit motion wiring drag chain structure. A cable penetrates through a main cable trunking at the upper part of a first-stage telescopic arm and reaches the lower end of the first-stage telescopic arm from the front end of the first-stage telescopic arm along the main cable trunking, then the cable is divided into two parts, one part of the two parts reaches a first-stage motor hood through a first-stage cable trunking and is connected with a related motor, the other part of the two parts enters in an inlet of a second-stage drag chain through a second-stage cable trunking and is divided into two parts at an outlet of the second-stage drag chain, then the other part is also divided into two branches, wherein the first branch reaches a second-stage motor hood and is connected with a related motor, and the second branch passes through the rear part of the second-stage motor hood and enters in a third-stage cable trunking, is inflected for 180 degrees at an outlet of the third-stage cable trunking, then enters in an inlet of a third-stage dray chain and then reaches a third-stage motor hood from an outlet of the third-stage drag chain to be connected with a third-stage motor. The multistage linear telescopic unit motion wiring drag chain structure has the advantages of skilful concept, compact structure, recirculating state ofwiring and flexible, safe and reliable motion of the cable.
Description
technical field [0001] The invention relates to the technical field of robots, in particular to a multi-stage linear telescopic unit motion wiring drag chain structure. Background technique [0002] Industrial robots have many degrees of freedom, most of which are tandem robot arms. The cable routing needs to be carried out along the robot arm. During the movement of the arm, the cable needs to use the drag chain structure to follow the movement, and there are multiple cable branches, so that the cable The wiring is very difficult, and it is easy to hinder the movement of the arm, and the cables interfere with each other, and the movement is blocked, which hinders the normal use of the robot. Contents of the invention [0003] The problem to be solved by the embodiments of the present invention is to provide a multi-stage linear telescopic unit movement wiring drag chain structure to overcome the defects in the prior art that the cable wiring hinders the movement of the...
