Embodiment 1
[0052] Embodiment 1: as figure 2 Shown is a specific embodiment of the present invention's focusing spot swing type laser roller type surface roughening processing device, which includes a laser 1 and a numerically controlled machine tool 3, and the said numerically controlled machine tool 3 adopts a conventional XL9 type numerically controlled machine tool. The working platform 12 driven by the translation guide rail 303 and the roll shaft 301 and the top 302 for installing the roll 13 are installed, and the roll shaft 301 and the top 302 are parallel to the translation guide rail 303 . The multi-prism scanning mechanism 4 and the integrated focus mechanism are housed on the described working platform 12, and the integrated focus mechanism consists of K=4 integrated focus heads (respectively the first integrated focus head 601, the second integrated focus head 602, the third integrated focus head 603 and the fourth integrated focusing head 604); and the laser 1 adopts high-p...
Embodiment 2
[0062] Embodiment 2: as figure 2 As shown, the surface roughening processing device of this focused light point swing type laser roller type provided by the present embodiment, its external structure is the same as that of embodiment 1, and the difference is that the first reflection in the polygon mirror scanning mechanism 4 of embodiment 1 The transmissive focusing lens 403 is replaced by the first transmissive focusing lens 404, and the internal structures of the four integrated focusing heads 601, 602, 603, 604 are all redesigned. Specifically taking the first integrated focusing head 601 as an example, in this embodiment, a second transmissive focusing mirror 7 and N=3 closely arranged focusing mirrors 901, 902 arranged opposite to the second transmissive focusing mirror 7 are provided in the present embodiment. , 903, such as Figure 8 as shown ( Figure 8 The high-speed motor 409 connected to one side of the polygon mirror 401 and the four beam splitting heads 405, 4...
Embodiment 3
[0063] Embodiment 3: as figure 2 As shown, the surface roughening processing device of this focused light point swing type laser roller type provided by the present embodiment, its external structure is the same as that of embodiment 1, and the difference is that the first reflection in the polygon mirror scanning mechanism 4 of embodiment 1 The transmissive focusing lens 403 is replaced by the first transmissive focusing lens 404, and the internal structures of the four integrated focusing heads 601, 602, 603, 604 are all redesigned. Specifically taking the first integrated focusing head 601 as an example, the present embodiment is provided with a second parabolic reflective focusing mirror 5 and N=3 closely arranged focusing mirrors 901 arranged opposite to the second parabolic reflective focusing mirror 5 , 902, 903, such as Figure 9 as shown ( Figure 9 The high-speed motor 409 connected to one side of the polygon mirror 401 and the four beam splitting heads 405, 406, ...
