Abstract

The invention discloses a method for realizing laser cleaning based on light beam peripheral scanning. Similar parallel light beams are irradiated to a rotary reflecting lens; the rotary reflecting lens is driven to rotate by a motor; and focal spots form a scanning trajectory to realize peripheral scanning. The invention further discloses a device for realizing laser cleaning based on light beamperipheral scanning; the device comprises a motor and the rotary reflecting lens; the lower end of the motor is connected with the rotary reflecting lens capable of rotating; the similar parallel light beams can be irradiated to the rotary reflecting lens; the reflected light beams are reflected by the rotary reflecting lens; and when the motor is rotated, the light beams reflected by the rotary reflecting lens form the scanning trajectory to realize peripheral scanning. The method and the device are uniform in scanning, high in cleaning efficiency, low in cost, long in life, low in mass, portable, simple and stable in overall structure and easy to realize.

Description

technical field

[0001] The invention relates to a beam scanning device, in particular to a method and device for realizing laser cleaning based on beam circular scanning, and belongs to the technical field of laser cleaning and the like. Background technique

[0002] As a new surface cleaning technology, laser cleaning has the advantages of no mechanical contact, no substrate damage, green environmental protection, and low operating cost. It has application prospects in the fields of mold cleaning, electronic component preparation, cultural relic protection and restoration, paint removal and rust removal. Very broad. Therefore, the research and development of laser cleaning technology and equipment has attracted great attention of researchers at home and abroad.

[0003] Laser cleaning mainly utilizes the characteristics of high energy density of laser, that is, a focused laser beam directly irradiates pollutants (or paint, rust, etc.) to cause physical or chemical changes ...
