Problems solved by technology

This requires wide spacing and makes maintenance difficult
[0008] 2) The mirror rocking structure includes acceleration and deceleration parts at both ends, so energy is concentrated at both ends resulting in uneven mass
[0009] 3) Traditional mirrors are difficult to deal with strong laser beams due to their small size
[0010] 4) The structure of the traditional polygonal mirror is complex
[0011] 5) When using a traditional polygon mirror, when the laser beam is a circular cross-section, many attenuated laser beams deviate from the reflective surface of the polygon mirror and are lost
Thus, the configuration of the conventional magnetic domain refinement device becomes complicated and the device becomes bulky

[0058] figure 2 is a schematic perspective view showing the configuration of a laser surface processing apparatus using beam section shaping and a polygon mirror according to a first embodiment of the present invention. A laser surface treatment apparatus using beam section shaping and a polygon mirror according to a first embodiment of the present invention includes a surface treatment kit 300 .

[0059] The surface treatment kit 300 includes a laser generator 20, first and second beam shaping units 30 and 40, a polygon mirror 50, a focusing mirror 60, and a controller (not shown). When the object 100 to be processed is wound or long, the surface treatment kit 300 further includes the conveying unit 10 .

[0060] The transport unit 10 transports the target object 100, and includes a conveyor. The conveying unit 10 conveys the object 100 at a speed ranging from 80 m / min to 200 m / min under the control of a controller described later. The conveying speed depends on the type ...

[0074] Figure 8 is a schematic perspective view showing the configuration of a laser surface processing apparatus using beam section shaping and a polygon mirror according to a second embodiment of the present invention. Explanation of the same components as those of the laser surface treatment apparatus according to the first embodiment of the present invention is omitted.

[0075] When a single surface treatment kit cannot cover the width of the target 100 due to the large width of the target 100 , at least two surface treatment kits are arranged in the width direction of the target 100 .

[0076] Figure 8 Four surface preparation kits 300a, 300b, 300c, and 300d are shown. Such as Figure 9 As shown, the corresponding laser generators 20a, 20b, 20c and 20d of the surface treatment kits 300a, 300b, 300c and 300d are arranged on the same plane perpendicular to the surface treatment kits 300a, 300b, 300c and 300d. The laser generators 20a, 20b, 20c, and 20d can be install...

Abstract

The present invention relates to a laser surface treatment apparatus and method using beam section shaping and a polygon mirror. In particular, the invention minimizes loss of an attenuated laser beam when radiated onto the polygon mirror by shaping a section of the laser beam with a means, and which can be made compact in size to facilitate maintenance by aligning laser generation means of each surface treatment kit on the same plane (provided that the apparatus has a plurality of surface treatment kits). The apparatus comprises surface treatment kit (300) including: laser generation means (20) for generating first laser beam (21) having a preset aperture; first beam shaping means (30) for shaping the section of first laser beam (21) to obtain second laser beam (22); second beam shaping means (40) for shaping the section of second laser beam (22) to obtain third laser beam (23); polygon mirror (50) onto which third laser beam (23) is irradiated, said polygon mirror rotating at a constant speed; condensing mirror (60) for condensing third laser beam (23) reflected from polygon mirror (50) to radiate fourth laser beam (24), with the fourth laser beam generating a spot on processing target (100); and means for interwork controlling of transfer speed of processing target (100), output of laser generation means (20) and rotation speed of polygon mirror (50).
