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.

Abstract

The invention relates to a long focal-depth laser cleaning head device and a cleaning method thereof. The long focal-depth laser cleaning head device comprises a laser generator; at the rear of the laser generator and along the heading direction of laser beams, a straightening lens, a protecting lens and a polarizer are sequentially arranged; a beam expander is arranged between the straightening lens and the protecting lens, a long focal length focus lens is arranged between the protecting lens and the polarizer, and a focus lens is arranged in the heading direction of the laser beams and at the rear of the polarizer. The long focal-depth laser cleaning head device is reasonable and novel in structural design and effectively ensures cleansing of uneven metal surfaces and reduce the requirements of laser cleaning on proficiency of workers, and workers only need to maintain the distance of the long focal-depth laser cleaning head device and a cleaned surface with a certain range, so that control convenience of the long focal-depth laser cleaning head device can be achieved, and the shortcoming of poor cleaning effects due to distance adjustment inaccuracy, and uniformity of the metal surface cleaned through the long focal-length laser cleaning head device can be effectively ensured.

Description

Technical field: [0001] The invention relates to a long focal depth laser cleaning head device and a cleaning method. 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, and t...
