Robot cable is professional application in the cable in the equipment such as robot, numerically-controlled machine tool, it has excellent bending resistance Bent and high flexibility feature, is being frequently bended in mobile occasion, 10,000,000 the recyclable torsion of robot cable, bending continuous cores Characteristic.Nearly 2 years, China's robot cable market capacity persistently expanded hair, and domestic robot cable industry development scale persistently increases Long, profit drives the innovation ability for resulting in mortar businesses to fall behind.Drug on the market for domestic market low end machines people cable now, And high-end robot cable is more rare.Occur in Integral cable industry concentration degree is low, dispersed technical resources, product science and technology Under the not high background of content, the enterprise of Depth Study robot cable will be the magic weapon for possessing the market competitiveness.Existed according to cable Purposes in robot is different, and robot cable is divided into 5 classes: robot body cable, drag chain cable (control cabinet-pedestal), control Cabinet processed-pedestal fixed cable, control cabinet connection wire, function cable.Wherein, two kinds of robot body cable, function cable It is whole imports, the country only has part of the manufacturer in the examination application stage, and there are no formally enter the field.

The common brand of robot body cable has an Europe system and two kinds Japanese, and the producer that the country develops earliest has that Jiangsu section is precious, It is developed since 2011, completes within 2013 20000000 drag chain tests, cable body application on site 4 years in 2015, reliability Obtain the preliminary identification in market.Mainly there are TK, K & S, IGUS, SAB etc. in Ou Xi producer, and mainly there are big electricity, OKI, day in Japanese producer It stands, mainly there are Jiangsu section treasured, the prosperous great achievement in Jiangsu etc. in domestic manufacturer.

Currently, being used on global robot Four Great families' robot body almost without the cable of Chinese Brand, domestic work Industry robot cable is badly in need of breaking through there are also the following aspects:

In terms of material: critical material also relies on import (alloy conductor, insulating materials, sheath material).

Design aspect: lack the dynamic cable design system and verify data of system.

Equipment aspect: precision is low, stability is poor, dynamic on-line monitoring systematic absence.

Production, QC Quality System: how to guarantee the repetition reliability of product.

Context of detection: the unprofessional reliability testing experiment room of most enterprises.

Practical application verifying aspect: the time is short, field is few, lacks industrial chain verification platform.
