A Laser-Assisted Weld Seam Intelligent Tracking System

Abstract

The invention discloses an intelligent tracing system for laser-assisted welding. The intelligent tracing system is used for welding a welding seam, and comprises a binocular stereoscopic vision locating module, a welding robot module and a laser-assisted feedback module, wherein the binocular stereoscopic vision locating module is located at a position where the module can shoot the welding seam; the welding robot module comprises a digital signal processor (DSP) control system, a welding gun adjustment device and a welding gun; the welding robot module has communication with the binocular stereoscopic vision locating module by signals; the welding robot module is in response to the parameter actions acquired by the binocular stereoscopic vision locating module; the laser-assisted feedback module comprises a laser sensor and a monocular camera; the laser-assisted feedback module is respectively connected with the binocular stereoscopic vision locating module and the welding robot module by a signal; the laser-assisted feedback module feeds back the detected parameters to the binocular stereoscopic vision locating module and the welding robot module; an optical filter is installed on a lens of the monocular camera.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a laser-assisted weld seam intelligent tracking system, which is used for weld seam welding and weld seam quality inspection. Background technique [0002] Welding is a low-cost, high-tech reliable process for joining materials. So far, there is no other process that is more widely used to join materials than welding and produces greater added value to the welded products. In China, no matter from the current development trend of welding equipment and material production ratio, or from the manufacturing technology and development direction of welding equipment and materials, my country's welding technology has made great progress, and some product technologies have reached or approached foreign countries. Advanced level, especially inverter welding technology. Welding is therefore the process of choice for successfully processing various materials into marketable products, now ...

AI Technical Summary

Problems solved by technology

[0003] However, most of the welding processes now rely on manual welding, and the accuracy and efficiency of welding are easily affected. Although there are some equipment that can realize automatic welding, the quality of the weld after welding cannot be well guaranteed. There is no regulatory mechanism for feedback
