Abstract

The invention discloses a welding track tracking system, method and device. The welding track tracking system comprises a processor (10), a coherent light scanner (20), a photosensitive element (30) and a laser welding device (40). The coherent light scanner (20) is used for emitting a scanning light beam and a reference light beam which interefer each other and carrying out the coherent light scanning on a welding area, wherein the coherent light scanning comprises at least one scanning line; the photosensitive element (30) is used for receiving an interference signal of the reflected light of the scanning light beam and the reference light beam and sending the interference signal to the processor (10); the processor (10) is used for determining the height information of the scanning lines according to the interference signals, determining a welding track according to the height information of the at least one scanning line and generating a welding control signal according to the welding track; and the laser welding device (40) is used for positioning a welding track according to the welding control signal.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a welding trajectory tracking method, device and system. Background technique [0002] In traditional welding technology, laser welding is widely used. Laser welding has many advantages such as high energy density, small heating area, long welding distance, various types of weldable materials, and easy automation of the welding process. It has been widely used in machinery manufacturing, aerospace, energy transportation, petrochemical and other industries. . However, laser welding also has the characteristics of nonlinear, time-varying and many interference factors. During the welding process, the welding seam will be deformed and the welding torch will deviate from the welding seam. Therefore, the welding trajectory of the welding seam needs to be automatically tracked during the welding process. [0003] Existing methods for tracking laser welding trajectory mostly use lase...
