Abstract

The invention relates to an anti-damage laser cleaning device. The anti-damage laser cleaning device comprises a laser device, a light beam shaping system, a scanning galvanometer system, a focusing system and a control system. A laser beam emitted by the laser device sequentially passes through the light beam shaping system, the scanning galvanometer system and the focusing system and is focused on the surface of a to-be-cleaned workpiece. The control system controls the laser device and the scanning galvanometer system to dynamically adjust the focal position of the laser beam in real time so that the cleaning work can be completed. The light beam shaping system is used for shaping an incident gauss beam into a flat-top light beam firstly and then conducting beam uniformizing conversion so that the edges of lasers can be sharper and the light intensity can be more uniform, and the surface of an object can be cleaned through the laser beam subjected to conversion without being damaged. The lasers reflected by the surface of the workpiece can be isolated through a polarization detection unit, and it is avoided that the reflected lasers damage optical devices.

Description

technical field [0001] The invention belongs to the technical field of laser applications, and relates to a laser cleaning device, in particular to a laser cleaning device for cleaning the surface of an object without damage. Background technique [0002] Object substrates such as object molds, weld surfaces, body shells, ship shells, rubber product surfaces, plastic product surfaces, aircraft skins, etc., as common objects in industrial cleaning, are prone to oil stains, rust layers, and residual paint in practical applications , glue, dust and other pollutants will cause changes in its surface roughness and mechanical properties, which will affect its performance. Therefore, it is necessary to clean its surface after a period of use or before surface pretreatment. Due to the particularity of cleaning objects, cleaning dirt, cleaning process and cleaning requirements, object cleaning is different from general chemical cleaning and soft surface cleaning. Although there are ...
