Abstract

The invention relates to the technical field of laser polishing and in particular relates to laser polishing equipment and method. The equipment comprises a first laser emitter, a pyrometer, a secondlaser emitter, a detector and a spectrograph, wherein the first laser emitter is used for emitting a first laser beam which is projected to a workpiece to be processed on a processing translation platform through a scanner to form a processing zone; the pyrometer is used for acquiring temperature data of the processing zone; the second laser emitter is used for transmitting a second laser beam toa detection focus; the detector is used for detecting a light signal at the detection focus under the action of the second laser beam; the spectrograph is used for acquiring spectrum information according to the light signal; a control device is used for controlling movement speeds of the processing translation platform and scanning speeds of the scanner in a scanning direction according to the spectrum information and the temperature data. Due to the arrangement, scanning speeds and moving speeds of the platform can be fed back and controlled according to the temperature data and the spectruminformation, and the problem that the size of a laser spot is affected as laser power is changed, and poor processing stability is caused, can be avoided.

Description

technical field [0001] The invention relates to the technical field of laser polishing, in particular to a laser polishing device and method. Background technique [0002] Laser polishing technology uses laser beam to scan and process the surface of the workpiece. Through the interaction between the laser and the workpiece to be processed, the excess material on the surface is removed to form a smooth plane. When the laser polishing technology is used to polish the workpiece to be processed, the Under the condition of material evaporation temperature, the higher the laser processing temperature, the better the processing efficiency and effect. [0003] The inventor found through research that when using the existing laser polishing technology to polish the equipment to be processed, the way to control the temperature of the laser treatment is usually to control the laser power output by the laser, but when changing the laser power output by the laser, the laser output by the...
