Description

Industrial robot body cable

Technical Field

The utility model relates to the technical field of cables, specifically speaking relates to an industrial robot body cable.

Background

When the industrial robot system works, the robot body needs to be bent, twisted or moved in three dimensions in a reciprocating manner for a long time. Conventional cables are statically mounted and are used to connect different components of a machine or device to provide power, transmit data, or control signals.

However, the application environment of the industrial robot is complex, and in many application cases, cables for transmitting power or data signals are required to be capable of following related components in the industrial robot, largely twisting or making three-dimensional motion for a long time, and being capable of bearing large torsional stress. Conventional cables, if applied in the above scenario, fail very quickly due to low material strength, unreasonable cable structure, and poor mechanical fatigue resistance. And the traditional cable uses a single-function cable, so that the wiring is complex and messy, and the wiring required space is large.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an industrial robot body cable reduces the wiring, can bear stronger torsion.

The utility model discloses an industrial robot body cable adopted technical scheme is:

the utility model provides an industrial robot body cable, the cable is by interior and outer cable core, band, weaving layer and the oversheath of including in proper order, the cable core includes specific elastic torsion center and encircles a plurality of sinle silks at torsion center, the sinle silk includes signal sinle silk, control core, hollow trachea, encoder sinle silk, power sinle silk and power brake sinle silk, the pitch of settlement has between each sinle silk.

Preferably, the outer sheath is made of a high strength, low viscosity material.

Preferably, the conductors of the plurality of wire cores are made of annealed copper wires.

Preferably, the control line core comprises four control line conductors.

Preferably, the encoder wire core comprises six encoder wire conductors.

Preferably, the signal wire core comprises five signal wire conductors.

The utility model discloses an industrial robot body cable's beneficial effect is: the power line, the brake line, the encoder line, the signal control line and the air pipe required by the multi-axis robot are highly integrated into a whole. The cable wiring is simple and tidy, and the wiring space is small. When the cable is subjected to external torsional stress, the torsional stress is borne by the middle torsional center instead of the wire core, so that the wire core is prevented from being disconnected when the cable is subjected to the external torsional stress. And the set pitch is arranged among the wire cores, so that the friction among the wire cores is reduced when the cable is twisted.

Drawings

Fig. 1 is a schematic structural diagram of the industrial robot body cable of the present invention.

Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1, the cable of the industrial robot body sequentially comprises a cable core 10, a wrapping tape 20, a braided layer 30 and an outer sheath 40 from inside to outside, the cable core comprises a specific elastic torsion center 11 and a plurality of wire cores surrounding the torsion center 11, the wire cores comprise a signal wire core 12, a control wire core 13, a hollow air tube 14, an encoder wire core 15, a power wire core 16 and a power brake wire core 17, and a set pitch is formed among the wire cores. The power brake cable core comprises a power cable and a brake cable.

The torsion centre 11 is made of a tensile fibre material. The torsion center 11 serves as a slow-release center of torsion around which each core wire rotates in a single layer or multiple layers (depending on the number of core wires) during the cabling process. After the cabling process is finished, the center of the middle torsion force keeps straight, and each wire core keeps a certain pitch and rotates around the tensile force center. When the cable is subjected to external torsional stress, the torsional stress is borne by the middle torsional center instead of the core wire, so that the structure can ensure that the core wire cannot be disconnected when the cable is subjected to the external torsional stress. And the set pitch is arranged among the wire cores, so that the friction among the wire cores is reduced when the cable is twisted.

The power line, the brake line, the encoder line, the signal control line and the air pipe required by the multi-axis robot are highly integrated into a whole. The wiring is simple and tidy, and the wiring space is small. The control sinle silk includes four control line conductors, and the encoder sinle silk includes six encoder line conductors, and the signal sinle silk includes five signal line conductors.

The outer sheath 40 is made of a high-strength low-viscosity modified polyurethane material. The high-strength low-viscosity material can ensure that the cable has high strength, low viscosity and good mechanical fatigue resistance, can ensure that the friction coefficient of a cable sheath is low, and the abrasion degree of the sheath is low in long-term use. At the same time, the high strength jacket can also bear a portion of the torsional stress, further preventing the core wire from breaking.

The signal wire core, the control wire core, the hollow air pipe, the encoder wire core, the power wire core and the conductors of the power brake wire core are all made of annealed copper wires. The flexibility and the mechanical fatigue resistance of the cable can be further improved by the annealed copper wires, and the service life of the cable is prolonged.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
