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

Embodiment Construction

[0058] The present invention will be further described below in conjunction with specific embodiments.

[0059] refer to figure 1 , a metal plate laser rust removal method, comprising the following steps:

[0060] (1) Use the spectral image acquisition system to collect surface images of metal sheets with different degrees of corrosion, establish a spectral database and extract spectral features;

[0061] (2) Use the spectral image acquisition system to collect the surface spectral image of the metal plate to be derusted;

[0062] (3) According to the hyperspectral database of different corrosion degrees, the corrosion degree of the metal sheet surface is evaluated;

[0063] (4) Restore the precise shape and position of the corroded area on the surface of the metal sheet, and input the corroded shape and position into the control terminal, and preset the moving speed, moving path and lifting position of the laser relative to the metal sheet;

[0064] (5) The control termin...

Abstract

The invention relates to a metal plate laser rust removal method. The method comprises the steps that the shape, position and thickness information of rust of a metal plate is obtained through a spectral image collection system, an operator can formulate the initial moving speed, moving path and lifting position of laser light relative to the metal plate, a control side can control the output power of a power generator of a laser output system in time according to signals fed back by an oscilloscope, and a moving device is controlled to move a laser device to a next rust area after the rust area is cleaned. Damage can be effectively prevented from being caused by laser light to the surface of the metal plate, and the work efficiency of laser rust removal is improved.

Description

technical field [0001] The invention relates to a metal surface treatment method, in particular to a laser rust removal method 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...
