Background technology

Industrial robot is applied to automobile industry the earliest, is usually used in welding, sprays paint, feeding, discharge and carrying.Industrial robot extends and expands the hands of people, foot and brain function, and it can replace the work that people is engaged in the adverse circumstances such as danger, harmful, poisonous, low temperature and Gao Re；Replace people to complete heavy, the dull duplication of labour, raise labour productivity, it is ensured that product quality.Industrial robot can form flexible manufacturing system and computer integrated manufacturing system with numerical control machining center, automatic transporting dolly and automatic checkout system, it is achieved the production automation.

China's " high-end equipment manufacture " 12 " development plan " and " intelligent manufacturing equipment " 12 " development plan " clearly propose the important content that industrial robot is intelligent manufacturing equipment development, and it is classified as the required Core equipment that China's equipment manufacture develops to high extreme direction, the production domesticization of industrial robot is irresistible as can be seen here, but the core key parts such as driver used by robot, motor, decelerator, foreign brand name still it is limited by so that localization process is by severe challenge including private cable.

Summary of the invention

The purpose of the technical program is to provide each positions such as being applicable to industrial machine human body, drag chain, pedestal, possess that good conductivity, shielding are good, torsion resistant and bending resistant strong, high abrasion, high intensity, low temperature resistant, oil resistant, weatherability and the industrial robot private cable of length in service life, specific as follows:

A kind of industrial robot cable, its structure is: constituted core by conductor outer wrapping insulating barrier；At least both threads core stranded composition line group；Many line groups are around the axis stranded composition cable core of cable, and are provided with filling in the axial location of cable；The outer from-inner-to-outer of cable core is enclosed with the first shielding protection layer, screen layer, secondary shielding overcoat and oversheath successively；

In described core: described conductor is formed by many tin-coated copper monofilament or many naked copper monofilament are stranded；Described insulating barrier is constituted for extruding fluorinated ethylene propylene copolymer Insulation Material outside conductor；The thickness of insulating barrier is not less than 0.23mm.

In described cable core: the stranded lay ratio of each line group is 9～12 times, direction of lay is left；Being filled to material is nylon, terylene or aramid fiber.

Described first shielding protection layer is identical with the material of secondary shielding overcoat, is all polytetrafluoroethylene PTFE band；

Described first and second shielding protection layer all uses and around packet mode, polytetrafluoroethylene PTFE band is wrapped in outside cable core, and their lapping angle is 40 °～45 °, and rate of putting up is not less than 25%；

Described screen layer uses the diameter tinned copper wire more than 0.12mm or bare copper wire braiding to constitute, and percentage of braiding coverage is not less than 90%.

Described oversheath is to extrude Polyurethane Thermoplastic Elastomer rubber TPU material outside secondary shielding overcoat to constitute.

As preferably:

In described core, the thickness of insulating barrier is 0.24～0.31mm；

In described cable core, the stranded lay ratio of each line group is 9～12 times；

Described first and second shielding protection layer all uses and around packet mode, polytetrafluoroethylene PTFE band is wrapped in outside cable core, and their lapping angle is 42 °～43 °, and the rate of putting up is 20～25%；

Described screen layer uses the tinned copper wire of diameter 0.14～0.16mm or bare copper wire braiding to constitute, and percentage of braiding coverage is 93～96%.

The effect of this cable is described as follows:

Reasonably lay ratio design (comprises conductor, line group, the control of cable core three aspect)；

It is less that first shielding protection layer extrudes mode outside dimension around packet mode ratio, thus more soft；

Reasonably screen layer size design, it is ensured that on the premise of function of shielding, reduces shielding filament diameter, more flexible；

Using TPU sheath material, its mechanical performance is excellent, and pliability is high, is suitable for Special use environment.

Compared with prior art, the super flexible anti-torque bending resistance requirement being adapted to industrial robot of this cable, torsion can be met, bend the requirement in service life moving more than 10,000,000 times.
