Automatic-zooming laser cleaning head device and cleaning method thereof

Abstract

The invention relates to an automatic-zooming laser cleaning head device and a cleaning method thereof. The automatic-zooming laser cleaning head device comprises a laser generator, a straightening mirror, a protecting mirror and a galvanometer are sequentially arranged on the rear side of the laser generator along the advancing direction of light beams, a beam expanding mirror is arranged between the straightening mirror and the protecting mirror, a liquid-state zooming lens is arranged between the protecting mirror and the galvanometer, and a focusing mirror is arranged on the rear side of the galvanometer along the advancing direction of the light beams. Therefore, the cleaning head device is reasonable and novel in structural design, cleaning of metal with an uneven surface by the laser cleaning head device is ensured effectively, requirements of laser cleaning on technical proficiency of workers are lowered effectively, the workers only need to maintain a distance between the laser cleaning head device and a cleaned face within a certain range, convenience in controlling the laser cleaning head device can be realized, the defect of poor cleaning effect caused by inaccurate distance adjusting is avoided, and uniformity of the laser cleaning head device in cleaning the surface of the metal is ensured effectively.

Description

Technical field: [0001] The invention relates to an automatic zoom laser cleaning head device and a cleaning method thereof. Background technique: [0002] Rust spots, corrosion, oil stains and other pollutant spots often appear on the surface of metal plates. There are many ways to clean metal in the transmission industry. Basically, chemical agents and mechanical methods are used for cleaning. With people's increasing awareness of environmental protection and safety Strengthening, my country's requirements for industrial environmental protection are also getting higher and higher. In the case of meeting environmental protection requirements, there are fewer and fewer types of chemicals that can be used in industrial production cleaning. The method of mechanical cleaning is to use contact cleaning, which has a mechanical effect on the surface of the object to be cleaned, which is easy to damage the surface of the object to be cleaned, and is also prone to secondary pollution...

AI Technical Summary

Problems solved by technology

The method of mechanical cleaning is to use contact cleaning, which has a mechanical effect on the surface of the object to be cleaned, which is easy to damage the surface of the object to be cleaned, and is also prone to secondary pollution, and the metal dust produced by contact cleaning is easy to be inhaled by workers, affecting workers' health

Laser cleaning has no grinding, non-contact, no thermal effect, and is suitable for cleaning the surface of various materials. It is the most reliable and effective metal cleaning method. At present, although laser cleaning of metal surfaces has been applied, there is a A hand-held laser cleaner, the hand-held laser cleaner in the prior art, in the process of use, requires workers to be able to accurately identify the distance between the hand-held laser cleaner and the cleaning surface, so as to ensure that the laser is on the cleaning surface In many places, the cleaning surface is mostly uneven, which requires workers to accurately adjust the distance between the laser cleaner and the cleaning surface. If the adjustment distance is not accurate, it will lead to uneven cleaning. The cleaning effect is poor, and it cannot meet people's requirements. It requires a lot of technical proficiency of workers, and it is difficult to achieve accurate distance control.
