[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0015] See also Figure 1 and Figure 2A coarse aggregate blue light scanning auxiliary device includes a base 1 and a horizontal turntable 2. The horizontal turntable 2 is rotatably mounted on the base 1. The horizontal turntable 2 is provided with a fixing assembly 3 for fixing the coarse aggregate 4. The fixing assembly 3 includes two damping turntables 301 arranged opposite each other and a plurality of transparent tensioning wires 302 connected between the two damping turntables 301. The rotation axis of the damping turntable 301 is perpendicular to the rotation axis of the horizontal turntable 2. The ends of the plurality of transparent tensioning wires 302 are tightened and fixed to the center points of the two damping turntables 301. The coarse aggregate 4 to be scanned is clamped and fixed between the plurality of transparent tensioning wires 302. As for the number of transparent tensioning wires 302, those skilled in the art can adjust it adaptively according to actual conditions. The number can be 5, 6, or even more, as long as the coarse aggregate 4 is clamped and fixed.

[0016] During scanning, the coarse aggregate 4 is clamped between the high-strength transparent tensioning lines 302, the auxiliary scanning device is placed under the three-dimensional blue light scanner, and the horizontal turntable 2 is rotated for multi-angle scanning. After the scanning of the upper surface of the coarse aggregate 4 is completed, the damping turntable 301 is rotated, and the coarse aggregate 4 is turned 180 degrees. The horizontal turntable 2 is rotated to perform multi-angle scanning on the lower surface of the coarse aggregate 4 to complete the blue light scanning of the entire coarse aggregate 4. The operation is convenient and fast, and the transparent tensioning line 302 is used to clamp the coarse aggregate 4, so there will be no problem of incomplete image scanning caused by tweezers clamping.

[0017] See also Figure 1 and Figure 2 Specifically, to facilitate precise control of the rotation angle of the damping dial 301, an angle scale (not shown) is provided on the damping dial 301. To facilitate rotation of the damping dial, a screw handle 5 is provided at the rear end of the damping dial. By screwing the screw handle 5, the damping dial 301 is driven to rotate. In this embodiment, when the damping dial 301 is rotated to the designed position, the damping dial 301 is released, and the damping dial 301 achieves self-positioning using its own damping force. This eliminates the need for additional positioning mechanisms, resulting in a simpler structure. The specific structure of the damping dial 301 is well known in the art and will not be further described here.

[0018] It is understandable that, in actual design, multiple groups of fixed components 3 can be arranged side by side on the horizontal turntable 2. Such a design enables scanning of multiple coarse aggregates 4 at a time, and scanning efficiency is significantly improved.
