Abstract

The invention discloses a two-dimensional laser spiral cleaning method. The laser cleaning system includes two orthogonally deflected digital vibrating mirror motors. On the mirror on the shaft of the digital galvanometer motor, after secondary reflection, the field lens is constrained to focus on the surface stains on the ablation target substrate in a two-dimensional plane; the interface protocol of the two digital galvanometer motors is XY2‑ 100; The two digital vibrating mirror motors are independently controlled. The two-dimensional laser spiral cleaning method of the present invention, for any point in the cleaning area, compared with line-by-line ablation, the laser returns to the vicinity of the point after completing the outer ring according to the spiral filling path, and the point area obtains cooling time, The heat accumulation effect of the laser is weakened; the progressive scanning speed is the speed of a single vibrating mirror motor, and the helical scanning speed is the vector sum of the two motor speeds. Therefore, compared with the progressive scanning method, the laser spiral cleaning effect is more uniform and the cleaning efficiency is higher. high.

Description

technical field

[0001] The invention relates to a two-dimensional laser spiral cleaning method, which belongs to the field of two-dimensional laser cleaning. Background technique

[0002] Two-dimensional laser cleaning means that the laser scans on a two-dimensional plane through the deflection of the galvanometer motor, and ablates the oil, rust or oxide layer on the surface of the target, so as to achieve the effect of cleaning the surface of the target. Based on the laser cleaning application of the galvanometer motor module, the existing scanning mode is line scanning and then line scanning again, which mainly has problems such as poor cleaning uniformity and low cleaning efficiency.

[0003] The poor cleaning uniformity is mainly due to the fact that in the progressive scanning mode of the galvanometer, the laser scans to the line edge area and undergoes a deceleration to reverse acceleration process, while the laser in the non-edge area maintains high-speed deflection....
