Abstract

The invention discloses a tensile detecting system for a 3-ring chain based on machine vision, which relates to industrial detecting equipment. The tensile detecting system for the 3-ring chain based on machine vision can detect the real-time overall size and the size of a single ring of the 3-ring chain in an original state and a stress state, and has higher detecting efficiency and accuracy. The tensile detecting system comprises a camera, an illuminating light source, a 3-ring chain, a 3-ring chain fixing device, a base, a force applying device, a guide rail, a force sensor and a computer system, wherein the camera is fixed right above the 3-ring chain; the illuminating light source is arranged on the base; the 3-ring chain fixing device is fixed on the base; the force applying device is arranged on the guide rail and can move on the guide rail; two ends of the guide rail are fixed on the 3-ring chain fixing device; the output signal ends of the force applying device and the camera are respectively connected with the computer system; and the computer system is used for processing image signals output by the camera and controlling the force applying device.

Description

technical field [0001] The invention relates to an industrial detection device, in particular to a three-ring chain tension detection system based on machine vision. Background technique [0002] The three-ring chain is a safety component for coal mine production and transportation, and its product strength directly affects the production and transportation of coal mines and the personal safety of miners. At present, there are few studies on the strength testing of the three-ring chain, and only involve the tensile test to break the three-ring chain. In this detection process, only the overall length of the three-ring chain when it is broken can be obtained, but there is no real-time detection of the deformation and stretching of the three-ring chain during the stress process, let alone detection of a single ring. At present, there is no device and method that can simultaneously obtain the high-precision size of the three-ring chain and the detection of the deformation and ...
