Problems solved by technology

In Cleaning World 2006,22(4):27-32, it is mentioned in the introduction of laser cleaning equipment that 10.6μm wavelength is used for cleaning, but this technical solution uses the method of loading objects on the platform. Due to the large load of the platform, when cleaning with high precision Small objects will cause disadvantages such as low cleaning efficiency and insufficient precision

Embodiment Construction

[0034] The principle of laser cleaning machine is to use high-energy laser focused on the surface of pollutants to ablate and gasify pollutants without damaging the workpiece body. For example, glue, dust, grease and other non-metallic materials have a high absorption rate of laser light, while the workpiece body absorbs laser light less, or the workpiece body absorbs laser light but the body is larger than the pollutants, and the heat dissipation is faster, without damaging the workpiece body , while the pollutants are gasified. The present invention proposes a cleaning device using a high-energy laser (which can be about 1 μm, or 10.6 μm, or a laser with other wavelengths). In addition, different wavelength lasers can be replaced according to different pollutants and workpiece materials. Metals, some plastics such as PT, PC, PE, etc., and paper objects can be cleaned with a 10.6 μm wavelength laser, while some objects can be cleaned with a 1 μm wavelength laser, and some sp...

Abstract

The invention relates to laser cleaning equipment. The laser cleaning equipment comprises a laser generating system, a light beam shaping system and a control system, and further comprises a detecting system, a 3D scanning galvanometer and a focusing system, wherein the laser generating system is used for generating a laser beam; the light beam shaping system is arranged on a laser beam light path; the laser beam is emitted by the laser generating system, sequentially passes through the light beam shaping system, the 3D scanning galvanometer and the focusing system until a to-be-cleaned workpiece; and the control system is used for dynamically regulating a focal position of the laser beam and completing cleaning work in real time by controlling the laser generating system, the detecting system and the 3D scanning galvanometer. According to the laser cleaning equipment, the 3D scanning galvanometer is adopted, so that high-precision cleaning with precision being a micron dimension of a curved-surface object or a plant object can be realized; and an XY working platform system also can be adopted to realize large-scale cleaning operation. Besides, the invention further discloses a splicing type cleaning mode based on the XY working platform and portable cleaning equipment based on the 3D scanning galvanometer.

Description

technical field [0001] The invention belongs to the technical field of laser applications, and in particular relates to a laser cleaning device, in particular to a curved or large-format laser cleaning device. Background technique [0002] There are various cleaning methods for traditional cleaning industrial equipment, most of which use chemical agents and mechanical methods for cleaning. Today, as my country's environmental protection laws and regulations are becoming more and more stringent, and people's awareness of environmental protection and safety is increasing, the types of chemicals that can be used in industrial production cleaning will become less and less. How to find a cleaner and non-destructive cleaning method is a problem we have to consider. Laser cleaning has the characteristics of non-abrasive, non-contact, low thermal effect and applicable to objects of various materials, and is considered to be the most reliable and effective solution. During the clea...
