Problems solved by technology

Patent No. 201820514466.7 provides an infrared detection device for fretting wear of electrical connectors, which is used to determine the distribution of debris on the surface of the electrical connector. However, it only observes the debris on the surface and cannot effectively solve this problem.
Patent No. 201921493880.5 provides a self-cleaning electrical connector assembly, but this device has no way to observe the wear condition of the contact surface, the specific cleaning effect cannot be guaranteed, and cannot be used as a reference for the reliability detection of connectors
The above-mentioned patents have made key researches in a single direction, but they still cannot completely solve the problem of debris between the contact surfaces of connectors. From this point of view, it is urgent to detect the reliability of connectors. device for cleaning

Abstract

The invention discloses an industrial robot electrical connector surface abrasion detection method and device. At present, 70% of failures of electronic and electrical equipment are caused by failuresof electronic components, wherein 40% of the failures are caused by failures of electrical connectors. According to the method, a reliability acceleration test is adopted, the surface of the connector is detected by changing the working temperature, the plugging speed, the plugging offset and the offset angle, the surface abrasion condition of the connector is observed, the roughness values of the connector under different working conditions can be conveniently estimated through a roughness calculation formula, and the reliability of the connector is improved, and then the change of the electrical performance of the connector under different working conditions can be seen by matching the plugging force. Besides, the surface of the connector is cleaned through a self-made cleaning device,so that the service life of the connector is prolonged. The test bench has the characteristics of rich test content, accurate test result, simple structure, convenient installation, simple and understandable operation and the like.

Description

technical field [0001] The invention relates to the technical field of industrial robots, in particular to a method and a device for detecting the surface abrasion of an electrical connector of an industrial robot and cleaning abrasive debris. Background technique [0002] As a basic electrical component, industrial robot electrical connectors are used to realize the transmission and control of electrical signals and the electrical connection between electronic and electrical equipment. The existence of industrial robot electrical connectors divides a huge structure into multiple interconnected small parts, making the large system structure modular and more flexible. Its service life and reliability affect and even determine the stability of the control system, communication system, data transmission and working voltage of the product. Therefore, through certain technical means to test the service life and reliability of the connector, check the technical defects in its str...
