The invention discloses a laser cleaning device and method for a multi-hole reticulate structure object. The laser cleaning method comprises the following steps that a three-dimensional model of a to-be-cleaned multi-hole reticulate structure object is obtained through a model obtaining unit; the three-dimensional model is treated by a model treatment unit, a multi-hole area and an entity area are obtained after dividing, and the laser cleaning parameters of the multi-hole area and the entity area are set up correspondingly; several groups of processing layer data are generated and stored in a database; and the processing layer data in the database are read by a parameter reading and outputting unit and output to a three-dimensional dynamic focus scanning system, and according to the processing layer data, the multi-hole area and the entity area are subjected to distinctive laser cleaning by the three-dimensional dynamic focus scanning system. According to the laser cleaning device and method for the multi-hole reticulate structure object, since the multi-hole area is subjected to fine cleaning, and the entity area without holes is subjected to fast cleaning, thorough cleaning of meshes is guaranteed, and cleaning efficiency is also improved.
Description
technical field [0001] The invention relates to a laser cleaning device and method for an object with a porous network structure, and belongs to the technical field of laser cleaning. Background technique [0002] Components with a porous network structure are necessary components of devices such as filters, porous electrodes, energy absorbers, mufflers, shock absorbers, electromagnetic shielding devices, heat exchangers, flame retardants, etc., according to different application requirements , the mesh structure of the porous network structure components is complex and diverse, and the properties of the constituent materials are also different. After being used for a certain period of time, the porous network structure component will cause the mesh to be clogged due to the adhesion of foreign matter or the timeliness of the functional layer on the surface of the material. In order to ensure the normal function of the device, it is necessary to effectively clean the mesh are...
