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, wherein a collimating mirror, a protective mirror and a vibrating mirror are sequentially arranged at the rear side of the laser generator in a travelling direction of a light beam; a beam expanding mirror is arranged between the collimating mirror and the protective mirror; a liquid-state zooming lens is arranged between the protective mirror and the vibrating mirror; and a focusing mirror is arranged at the rear side of the vibrating mirror in the travelling direction of the light beam. The cleaning head device is reasonable and novel in structural design, effectively guarantees cleaning on an uneven metal surface, effectively reduces requirements on technical proficiency of a worker of laser cleaning, can realize convenience in laser cleaning head device control by keeping a distance between the laser cleaning head device and a cleaning surface within certain range by the worker, avoids the defect that cleaning effect is poor as a result of inaccurate distance adjustment, and effectively guarantees uniformity of cleaning the metal surface by the laser cleaning head device.

Description

Technical field[0001]The present invention relates to an automatic zoom laser cleaning head device and a cleaning method thereof.Background technique[0002]The surface of the metal sheet often occurs, corrosion, oil and other pollutant spots. There are a variety of ways in the transmission industry. Basically, the chemical and mechanical methods are used to clean, and the increasing people's awareness is increasing. Strengthening, my country's requirements for industrial environmental protection are also increasingly high, and in the case of environmental protection requirements, the types of chemical drugs that can be used in industrial production cleaning are less and less. Method of mechanical cleaning is to use contact cleaning, which is mechanically for the surface of the cleaner, and it is easy to damage the surface of the cleaned product, and it is easy to produce secondary pollution, and the metal dust produced by the contact cleaning is easily inhaled, affecting the workers....

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.
