Intelligent focal length control system for laser rust removal

Abstract

The invention relates to the technical field of laser rust removal, and discloses an intelligent focal length control system for laser rust removal. The system comprises a base, a first speed reduceris installed at the front end of the base, a focal length control box is installed at the lower end of the inner side of a clamp, a laser head is installed at the bottom end of the focal length control box, a camera is installed on one side of the focal length control box, and three displacement sensors are installed at the position, close to the outer side of the laser head, of the upper end of the focal length control box. According to the intelligent focal length control system, real-time shooting is carried out on a to-be-derusted workpiece by the camera; the size and shape of the workpiece and the rust position on the surface of the workpiece are obtained; real-time distance measurement is carried out on the two sides of a to-be-derusted position through the three displacement sensors; and the distance and angle of the laser head are adjusted through a first rotating joint motor, a second servo motor, a second rotating joint motor and a first servo motor, the position of the laserhead can be accurately controlled, optimal focal length control is achieved, the purpose of efficient rust removal is achieved, and damage to the workpiece is reduced as much as possible.

Description

technical field [0001] The invention relates to the technical field of laser rust removal, in particular to an intelligent focus control system for laser rust removal. Background technique [0002] The traditional rust removal industry has a variety of rust removal methods, most of which use chemical agents and mechanical methods for rust removal. Laser rust removal has the characteristics of no grinding, non-contact, and no thermal effect. At the same time, laser rust removal can solve the problem of using traditional rust removal methods. The problem that cannot be solved by the rust removal method, because the laser is non-contact cleaning of the workpiece, it is very safe to clean the precision workpiece or its fine parts, and its accuracy can be guaranteed.

AI Technical Summary

Problems solved by technology

[0003] For large steel components such as steel beams, due to the large overall size, heavy weight, large welding penetration, and large deformation, the error of the focal length of the laser derusting process is required to be ±1mm, but the size error of the steel beam processing, welding deformation and other factors cause The error has reached 3-5mm, which greatly exceeds the laser focal length requirement, which leads to poor rust removal effect
