Industrial robot reliability test device and test method

Abstract

The invention discloses an industrial robot reliability test device and an industrial robot reliability test method. The industrial robot reliability test device comprises horizontal iron, a servo feeding system, a detection system and a control system, the detection system comprises an environment detection device, a laser displacement sensor, a reflection device and a servo electromagnet. The environment detection device, the laser displacement sensor and the servo electromagnet are mounted at the tail end of the industrial robot; the servo feeding system feeds the reflection device, the test is carried out at different positions, the servo electromagnet grabs and replaces weights with different weights, and the test is carried out. The load change of the industrial robot and the power supply voltage change of the industrial robot are simulated, the reliability test of the industrial robot simulating the actual working condition is carried out, the reliability test of the industrial robot is more complete, the reliability of the test is improved, and the reliability and stability are higher. And the reliability level of the industrial robot is comprehensively tested.

Description

technical field [0001] The invention belongs to a test device in the field of automatic precision testing of industrial machinery manufacturing, more specifically, the invention relates to a reliability test device and a test method of an industrial robot. Background technique [0002] At present, industrial robots have been applied to important fields such as manufacturing, and their reliability test devices have also been widely used in the field of machinery manufacturing automation. The working accuracy of the industrial robot mainly depends on the working accuracy of the robot end, which is an important indicator reflecting the performance and reliability of the industrial robot; [0003] The existing industrial robot accuracy testing methods mainly use a laser tracker to test the pose accuracy of the industrial robot end. The existing industrial robot pose test device is mainly a laser tracker. Although it has the advantages of high measurement accuracy and fast speed...

AI Technical Summary

Problems solved by technology

The existing industrial robot pose testing device is mainly a laser tracker. Although it has the advantages of high measurement accuracy and fast speed, this instrument also has limitations on the site and space required for measurement, which is not conducive to the on-site operation and measurement of industrial robots. , and the instrument cost is higher and the operation is more complicated

Moreover, the existing traditional low-cost industrial robot reliability test devices are all tested under the condition of no load, which cannot be called a real industrial robot reliability test.

In the case of a load, it does not conform to the test results of the pose accuracy test method, and the test results of such a traditional test method cannot accurately characterize the working accuracy of industrial robots.
