A large format laser cleaning machine

Abstract

The invention relates to a device for washing pollutants including rust spots, corrosion, oil stains and the like on surfaces of various types of metal sheet materials and particularly relates to a large-breadth laser washing machine. The large-breadth laser washing machine comprises a worktable, wherein a conveyor belt driven by a stepping motor is arranged on the worktable along the length direction of the worktable; the bottom of a supporting frame is mounted on the two sides of the worktable; a hoisting mechanism is arranged on the supporting frame; and the two ends of a hoisting transverse beam, which are arranged along the width direction of the worktable, are connected with the hoisting mechanism respectively. Therefore, the structure is reasonable and novel in design and has no grinding, non-contact and no heat effects in a washing process; in the washing process, no pollution to the environment is caused and body health of workers is not injured; a washing area is large, the efficiency is high and the washing cost is low; the distance between the device and a washing surface can be accurately controlled and the washing is uniform and has good effect.

Description

Technical field: [0001] The invention relates to a device for cleaning pollutants such as rust spots, corrosion and oil stains on the surface of various metal plates, in particular to a large-format laser cleaning machine. Background technique: [0002] There are many ways to clean metal in the traditional industry, basically using chemical agents and mechanical methods for cleaning. With people's increasing awareness of environmental protection and safety, 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 mechanical force 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 produce...

AI Technical Summary

Problems solved by technology

The method of mechanical cleaning is to use contact cleaning, which has mechanical force 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. affect the health of workers

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, due to The distance between the cleaning surfaces and the adjustment between the laser frequencies are very demanding and difficult to implement. Therefore, laser cleaning has not been widely used. Although there is a handheld laser cleaner on the market, due to its structural limitations, The cleaning area is small, the cleaning efficiency is low, and it cannot be used for large-scale cleaning, and the distance between the handheld laser cleaner and the cleaning surface is not easy to control accurately, resulting in uneven cleaning and poor effect, which is far from meeting people's requirements.
