The novel robot cable
Technical field
The utility model relates to the cable technology field, relates to a kind of application cable of robot system in particular.
Background technology
Common PVC flexible cable generally may be used on the crooked place of moving and is meant that artificial crooked take-up once in a while carries out with the equipment displacement simultaneously, or the bending of space mounting is connected up.Better slightly also just the directional curvature of level or vertical direction move, and all be to have common indoor environment to carry out.
And at present; Automated productin line, robot system, automatic assembling and disassembling system and mechanical arm application places; Need a kind of high flexibility and can power source, control signal source or monitoring feedback signal source be provided free bending motion cable transmission arbitrarily; The application characteristic of this cable can with move parts, handgrip and robotic arm frequent about, motion or Periodic Rotating motion bend right and left; The distortion power that the motion of the free bend of these several kinds of forms of expression is produced can influence useful life and the safe transmission ability that shortens cable, promptly use the short period after the conduction cable core very easily rupture or insulation and the breakage of sheath protective layer.This cable application is to various abominable industrial environments (like high low temperature, greasy dirt, water, soda acid, chemicals etc.) simultaneously; And rub for a long time with mechanical arm; So; In order to satisfy the needs of automated productin line, robot system, automatic assembling and disassembling system and mechanical arm application places safe transmission power supply and signal source, manufacture and design a kind of anti-free bend motion, anti-abominable industrial environment for use, anti abrasive cable necessitates.
The utility model content
The purpose of the novel invention of this practicality is the technical deficiency that overcomes PVC flexible cable application facet, provides a kind of anti-free torsional motion, high abrasion, the robot system of suitable abominable industrial environment high life to use high flexibility specialty cable.
The purpose of the utility model is to be achieved through following technical proposals:
A kind of novel robot cable is twisted together by signaling control unit, signal detection feedback unit, power unit, filling member and to form the whole piece cable core; Cable core outerwrap inner restrictive coating; Wrap up external sheath layer again in the inner protective layer outside; It is characterized in that described power unit is formed by extruding the elastomeric insulating barrier of one deck around the transmission heart yearn, described transmission heart yearn is by the conductor reinforcement and conducting element is stranded constitutes; Described signaling control unit is to be formed by transmission heart yearn spiral pair twist more than two or two; The wrapped internal shield of peripheral forward is made the soft polyester band of reverse wrapped one deck on the described internal shield, described signal detection feedback unit is identical with the signaling control unit design.Described conducting element is that pliability is conducted electricity copper cash preferably, and described filling member is a plastic strip, and described internal shield is an aluminium-plastic tape, and the peripheral one deck copper wire that evenly closely twines of described inner restrictive coating is formed outer shielding layer.
Technique scheme is done further to improve, it is characterized in that described filling member is in the cable core center, its overall dimension, circle are directly consistent with the transmission heart yearn, and the benefit of this programme is to stablize cable core structure, is difficult for malformation when making the cable torsional bending.
Technique scheme is done further to improve; It is characterized in that; The plastic material that extrudes one deck PUR around the described outer shielding layer perhaps is similar to the thermoplastic elastomer (TPE) and the rubber type of material of this material; The benefit of this programme is the stability and the suitable environment application requirements of protective wire cable structure, possesses wear-resisting and counter-bending torsion capacity simultaneously.
Technique scheme is done further to improve, it is characterized in that described conductor reinforcement is the high-strength polyester fiber, the benefit of this programme is promptly to have strengthened the conducting element bending strength, can reduce bending stress again, improves useful life.
Technique scheme is done further to improve, it is characterized in that, described insulating barrier is the thermoplastic elastic insulating barrier of low medium.

Embodiment
A kind of novel robot cable is twisted together by signaling control unit 10, signal detection feedback unit 2, power unit, filling member and to form the whole piece cable core; Extrusion molding filling member 3 is in the cable core center, and its overall dimension is consistent with power unit 1, and approaching with signal detection feedback unit 2 circle footpaths with signaling control unit 10; Help the stable of lay configuration like this, cable core outerwrap inner restrictive coating 7 wraps up external sheath layer 9 again in inner protective layer 7 outsides; It is characterized in that described power unit 1 extrudes the elastomeric insulating barrier 4 of one deck by transmission around the heart yearn to be formed, described transmission heart yearn is to constitute by conductor reinforcement 5 and conducting element 6 are stranded; Described signaling control unit 10 is to be formed by transmission heart yearn spiral pair twist more than two or two, and it is right to constitute signal, transmission indifference signal; The wrapped internal shield of peripheral forward, isolating exterior disturbs, and makes the soft polyester band of reverse wrapped one deck on the described internal shield; 10 designs of described signal detection feedback unit 2 and signaling control unit are identical, and described insulating barrier is the thermoplastic elastic insulating barrier of low medium, and described conducting element 6 conducts electricity copper cash preferably for pliability; Described conductor reinforcement 5 is the high-strength polyester fiber, promptly strengthens conducting element 5 bending strengths, can reduce bending stress again; Described filling member 3 is a plastic strip; Described internal shield is an aluminium-plastic tape, and one deck copper wire composition outer shielding layer 8 is evenly closely twined in described inner restrictive coating periphery, and at its thermoplastic elastomer (TPE) and rubber type of material that extrudes the plastic material of one deck PUR on every side or be similar to this material; The stability of protection cable and the application requirements that conforms possess wear-resistant and counter-bending torsion capacity simultaneously.
