Abstract

The invention discloses a laser cleaning system based on robot control and a cleaning method thereof. The laser cleaning system comprises a computer system, a laser, a protective cover, a sensing system, a light beam shaping system, a waste processor, an optical spectrum analyzer and a workpiece to be cleaned, and further comprises a robot, wherein the laser and the robot are both connected with the computer system; the light beam shaping system is connected with the laser through an optical fiber; the sensing system and the light beam shaping system are both fixed in the protective cover; the sensing system is connected with the computer system; the protective cover is fixed on a robot arm; and the optical spectrum analyzer is connected with the computer system. The laser cleaning system and cleaning method can clean workpieces to be cleaned with any size and random shapes, can analyze cleaning results in real time to realize closed-loop control, judge the cleaning effect through image processing and optical spectrum analysis, and are accurate in judgment and excellent in cleaning effect; and the robot automated control improves the system adaptability and stability.

Description

technical field [0001] The invention belongs to the technical field of laser cleaning, and in particular relates to a laser cleaning system based on robot control and a cleaning method thereof. Background technique [0002] There are many kinds of traditional methods of cleaning workpieces, including ultrasonic cleaning, mechanical cleaning and wet chemical cleaning, but they all have limitations. The ultrasonic cleaning method uses ultrasonic waves to generate vibrations to remove residues on the surface of the workpiece. The workpiece needs to be placed in the cleaning solution, which is difficult to dry after cleaning, and the removal effect on nano-scale residues is poor; the mechanical cleaning method uses mechanical means to remove Residues on the surface of the workpiece, such as sandblasting, brushing and scraping, etc., this method is easy to damage the workpiece, and cannot meet the required cleanliness; wet chemical cleaning method is to remove by soaking, sprayin...
