Robot cables are specifically developed for high mechanical pressure in the robotics industry. This type of robot cable must withstand millions of alternating bending cycles as well as tensile and torsional stresses. In addition, there are the most different requirements based on temperature, petroleum, and chemical resistance. In order to meet these high requirements, robot cables are tested for performance and resistance in the testing system
Currently, there is no international subdivision standard for cables used in robots. TUV Rheinland has been recognized by the public in photovoltaic cables, so they released the TUV 2 pfg 2577/08.16 standard in July 2016. However, this standard still has a certain degree of popularity in the domestic market, but has not been applied abroad
The common standard in China is that the Robotics Industry Alliance released CRIA 0003-2016 Industrial Robot Special Cable: Robot Cable Mechanical Test Standard
GB/T 5013 (IEC 60245) Rated Voltage 450750V and Below Rubber Insulated Cable
GB/T 5023 (IEC 60227) Rated voltage 450/750V and below PVC insulated cables
GB/T 18380.12 single vertical combustion
The bending test for robot cables can include:
90 degree bending, 180 degree bending, two wheel bending, drag chain bending, rotational bending, rapid bending
1. Bending
This is a cantilever that may be used to simulate multi joint robots, One end is fixed in the lower right corner, and the other end is rotated, with a bending speed of 200flexings/min, at least 30000 times
2: 90 degree bending (> 4mm2)
During the test, the cable is free forged to sway left and right within the 180 degree range, with a rotation rate of 40 times per minute, and a total of 1 million times is required. Because the point of each bend is located between two fixed parts and the operation is repeated at the same point, the requirements for this test are relatively strict
3. Bending of double pulleys (≤ 4mm2)
This test assesses the overall flexibility performance of the cable under radial tensile force and voltage and current load applied to the core
4. Vertical Torsion
When conducting a vertical torsion test, there is a fixed end below, which rotates at a relatively large angle of 12 times per minute
Function of testing report:
