Laser derusting system of sheet metal

Abstract

The invention relates to a laser derusting system of sheet metal. The system comprises a hyperspectral image acquisition device and a support plate for bearing the sheet metal and further comprises atransverse movement mechanism, a longitudinal movement mechanism, a vertical movement device, a laser output system, a monitoring system, a gas injection system, a collection system and a control terminal, wherein the laser output system and the support plate are arranged on the upper side of the longitudinal movement mechanism; the vertical movement device is arranged on the two sides of the support plate and fixedly connected with the transverse movement mechanism; according to a cleaning system, three-dimensional motion of the laser output system relative to the sheet metal is achieved by matching of the transverse movement mechanism, the longitudinal movement mechanism and the vertical movement device; the monitoring system is used for monitoring a cleaning state of a rusting area on the surface of the sheet metal; the gas injection system is used for spraying boosting gas to blow stripped residue off a laser cleaning area; and the collection system is used for collecting the stripped residue.

Description

technical field [0001] The invention relates to a metal surface treatment device, in particular to a laser rust removal system for metal plates. Background technique [0002] Metal materials are damaged by the action of the surrounding medium, which is called metal corrosion. Metal rusting is the most common form of corrosion. During corrosion, a chemical or electrochemical heterogeneous reaction occurs at the interface of the metal, which turns the metal into an oxidized (ionic) state. This will significantly reduce the mechanical properties of metal materials such as strength, plasticity, and toughness, destroy the geometry of metal components, increase wear between parts, deteriorate electrical and optical physical properties, shorten the service life of equipment, and even cause disasters such as fire and explosion. sex accident. [0003] At present, there are many methods for removing rust on metal surfaces, and the rust on the surface of different types of metal mat...

AI Technical Summary

Problems solved by technology

However, the chemical immersion method and the electrochemical rust removal method consume a large amount of chemical reagents, and the sewage process is complicated

[0004] Moreover, since the rust spots on the surface of the metal sheet usually only exist in some areas, the traditional chemical immersion method, electrochemical derusting method, and mechanical derusting method all perform derusting operations on the entire surface, and cannot perform targeted derusting on the rusty spots. Rust treatment not only damages the normal plate area, but also increases the cost of rust removal
