Multi-laser-head intelligent laser cleaning method and device

Abstract

The invention discloses a multi-laser-head intelligent laser cleaning method. The method comprises the steps of S1, acquiring a three-dimensional shape of a to-be-cleaned workpiece, and determining abe-cleaned area; S2, determining a motion track and a scanning mode of each laser head according to the three-dimensional shape of the to-be-cleaned workpiece and be-cleaned area; S3, selecting technological parameters of all laser heads, and moving all the laser heads along the motion track and emitting laser to clean the surface of the workpiece; and S4, acquiring an image of the cleaned workpiece surface in real time, detecting the workpiece surface cleaning condition by using an image processing algorithm, and if the preset requirement is not met, returning to the step S3 until the detection result meets the preset requirement. The multiple laser heads can be matched with one another to clean dirt on the surface of the workpiece, and the laser cleaning method is particularly suitable for cleaning surfaces with large breadth and complex shape and structure, and has the advantages of being high in cleaning efficiency, good in cleaning quality and the like.

Description

technical field [0001] The invention relates to the technical field of laser cleaning, in particular to an intelligent laser cleaning method and device with multiple laser heads. Background technique [0002] Laser cleaning is a new green cleaning technology developed in the last 20 years. This technology uses high-frequency pulsed laser to act on the surface of the workpiece to be cleaned, so that the dirt is separated from the surface of the workpiece by gasification, burning, peeling, etc., and finally achieves purpose of cleaning. In the laser cleaning process, there is no chemical pollution, no noise pollution, and no air pollution, which is a typical green manufacturing technology. Laser cleaning equipment uses high-frequency pulsed fiber laser as the light source, so the equipment is maintenance-free and has no consumables. From the perspective of the entire life cycle of the product, it has high economic benefits. This technology has been used in industrial rust rem...

AI Technical Summary

Problems solved by technology

Therefore, when cleaning a large-format or complex-shaped cleaning surface, the cleaning efficiency of a single laser head is low, and the cleaning quality is poor, which cannot reach the level of industrial-grade production applications.

In addition, it is difficult for a single laser head to clean a thick rust layer with a thickness greater than 0.2 mm. It is difficult to remove it at one time. It requires repeated laser scanning and multiple scanning of the cleaning surface to comp
