Laser cleaning device

Abstract

The invention discloses a laser cleaning device. The laser cleaning device comprises a laser generator, a shell, a field lens and a galvanometer, wherein an output end of the laser generator is connected with an optical fiber; an end part of the optical fiber is arranged on the shell through an optical fiber splice; the field lens is arranged at the bottom of the shell; the galvanometer is arranged on the shell; the bottom of the galvanometer extends to the inside of the shell by passing through the shell; a driving motor is arranged above the galvanometer; an output shaft of the driving motoris connected with the galvanometer; a sealing cover plate is arranged on one side of the shell; a focus lens is arranged inside the field lens; and an end part of the shell is connected with a mechanical arm. The laser cleaning device is small in size, and simple in structure. The angle and position of the laser cleaning device can be adjusted through cooperative use with the mechanical arm, so that the focal length between the laser cleaning device and a workpiece is kept consistent; the cleaning quality is improved; dead-angle-free cleaning of the workpiece is realized; the working efficiency is improved; the application range is enlarged; and the use cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of laser cleaning, in particular to a laser cleaning device. Background technique [0002] In recent years, with the enhancement of people's awareness of environmental protection, it has brought huge challenges to the development of the cleaning industry worldwide. Various cleaning technologies that are beneficial to environmental protection have emerged, and laser cleaning technology is one of them. Laser cleaning technology It refers to the use of high-energy laser beams to irradiate the surface of the workpiece, so that the dirt, rust or coating on the surface evaporates or peels off instantly, and effectively removes the surface attachment or surface coating of the cleaning object at high speed, so as to achieve a clean process. It is based on laser A new technology that interacts with substances, different from traditional mechanical cleaning methods, chemical cleaning methods and ultrasonic cleaning me...

[0002] In recent years, with the enhancement of people's awareness of environmental protection, it has brought huge challenges to the development of the cleaning industry worldwide. Various cleaning technologies that are beneficial to environmental protection have emerged, and laser cleaning technology is one of them. Laser cleaning technology It refers to the use of high-energy laser beams to irradiate the surface of the workpiece, so that the dirt, rust or coating on the surface evaporates or peels off instantly, and effectively removes the surface attachment or surface coating of the cleaning object at high speed, so as to achieve a clean process. It is based on laser A new technology that interacts with substances, different from traditional mechanical cleaning methods, chemical cleaning methods and ultrasonic cleaning methods (wet cleaning processes), it does not require any CFC organic solvents that destroy the ozone layer, no pollution, no noise, Harmless to the human body and the environment, it is a "green" cleaning technology; the existing laser cleaning device is generally a hand-held laser cleaner, and the worker holds the laser cleaner to clean the working surface, which is labor-intensive and low-efficiency. During the cleaning process, the focal length between the laser cleaner and the workpiece varies greatly, and the consistency of cleaning quality cannot be guaranteed. The handheld laser cleaner is large in size and complex in structure. Some places with narrow spaces cannot be cleaned, which reduces the scope of use.
