[0002] With the rapid development of industrial manufacturing, reverse engineering, and cultural relic preservation, the demand for high-precision scanning of the three-dimensional shape of objects is becoming increasingly urgent. As the core equipment for acquiring three-dimensional data of objects, the scanning efficiency, accuracy, and ease of operation of laser scanners directly affect the quality of subsequent work.

[0003] Existing laser scanners have several shortcomings in use: some scanners can only perform linear scanning in a single direction or rotational scanning at a fixed angle, making it difficult to achieve full coverage of complex structures, resulting in blind spots and requiring multiple adjustments to the object or scanner position, which is cumbersome and inefficient; some scanners with composite motion functions use multiple drive motors to control movement and rotation separately, which is not only structurally complex and costly, but may also affect scanning accuracy due to multi-motor coordination errors; in addition, as precision equipment, scanners are susceptible to dust, impacts, etc. when not in operation, and the protective structures of existing equipment are mostly manually operated, with low automation and difficulty in linking with the scanning process, resulting in poor ease of use. In view of this, we propose a high-precision 3D laser scanner to solve the existing problems. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] like Figures 1-5 As shown, the present invention proposes a high-precision three-dimensional laser scanner, including a movable cabinet 1, a scanning mechanism 2, a protective mechanism 3, and a control switch. The movable cabinet 1 is provided with a threaded scanning mechanism 2 on its upper side, and the movable cabinet 1 is provided with a protective mechanism 3 inside. The scanning mechanism 2 is equipped with a scanner, the protective mechanism 3 is used to protect the scanner, and the movable cabinet 1 is provided with a control switch 4 on its surface.

[0023] In an optional embodiment, the scanning mechanism 2 includes a fixed frame 201, a threaded rod 202, a moving platform 203, a guide rod 204, a rotating seat 205, a guide plate 206, a drive motor 207, a first bevel gear 208, a second bevel gear 209, a third bevel gear 210, a fourth bevel gear 211, and a threaded sleeve 212. The fixed frame 201 is symmetrically arranged on the upper surface of the moving cabinet 1. The threaded rod 202 and the guide rod 204 are movably connected to the fixed frame 201, and the moving platform 203 is movably connected to both the guide rod 204 and the threaded rod 202. The drive motor 207 is arranged inside the moving platform 203. The output end of the drive motor 207 is fixedly connected to the third bevel gear 210. The threaded sleeve 212 is arranged on the threaded rod 202 of the moving platform 203. The fourth bevel gear 211 is arranged on one side of the threaded sleeve 212. The third bevel gear 210 and the fourth bevel gear 211 mesh with each other.

[0024] In an optional embodiment, a second bevel gear 209 is movably connected to the mobile platform 203, and a rotating seat 205 is movably connected to the second bevel gear 209 on the mobile platform 203. A first bevel gear 208 is provided between the drive motor 207 and the third bevel gear 210, and the first bevel gear 208 and the second bevel gear 209 mesh with each other.

[0025] After the drive motor 207 starts, the output end drives the third bevel gear 210 to rotate. Since the third bevel gear 210 meshes with the fourth bevel gear 211 on one side of the threaded sleeve 212, the power is transmitted to the fourth bevel gear 211, which in turn drives the threaded sleeve 212 to rotate synchronously. The threaded sleeve 212 and the threaded rod 202 form a threaded engagement. When the threaded sleeve 212 rotates, it will generate a linear displacement along the axial direction of the threaded rod 202. The guide rod 204 restricts the rotational freedom of the moving platform 203, allowing it to only make smooth linear motion along the threaded rod and the guide rod.

[0026] The output of the drive motor 207 simultaneously drives the first bevel gear 208 to rotate. The first bevel gear 208 meshes with the second bevel gear 209 on the moving platform 203, transmitting power to the second bevel gear 209. When the second bevel gear 209 rotates, it directly drives the rotating seat 205 to rotate around its own axis. The scanner mounted on the rotating seat 205 rotates with the rotating seat 205, enabling multi-angle scanning of the outside world, reducing blind spots, and achieving composite scanning while moving and rotating, greatly improving scanning efficiency and coverage.

[0027] In an optional embodiment, the protective mechanism 3 includes a linkage 301, a transmission rod 302, a limiting frame 303, a movable shaft 304, a limiting block 305, a protective cover 306, and a rotating shaft 307. A guide plate 206 is fixedly connected to one side of the mobile platform 203, and a linkage 301 is movably connected to one side of the guide plate 206. A movable shaft 304 is movably connected inside the mobile cabinet 1, and a transmission rod 302 is movably connected to the movable shaft 304. The transmission rod 302 is movably connected to the side of the linkage 301 away from the guide plate 206. A limiting frame 303 is provided on the upper surface of the mobile cabinet 1 near the mobile platform 203, and a limiting block 305 is movably connected to the limiting frame 303. A protective cover 306 is fixedly connected between the limiting blocks 305.

[0028] In an optional embodiment, the protective cover plate 306 is provided with a rotating shaft 307, and the side of the transmission rod 302 away from the linkage 301 is movably connected to the rotating shaft 307. A scanner is installed on the rotating seat 205, and the scanner and the protective cover plate 306 cooperate with each other.

[0029] When the scanning mechanism 2 is started, the moving platform 203 moves linearly along the threaded rod 202 and the guide rod 204. The guide plate 206 fixed on one side of the moving platform moves along with it. The guide plate 206 is movably connected to the linkage 301. Therefore, the linear displacement of the guide plate 206 will drive the linkage 301 to push and pull. The end of the linkage 301 away from the guide plate is movably connected to the transmission rod 302. When the linkage 301 is pushed and pulled, it will drive the transmission rod 302 to rotate and swing around the movable shaft 304. The moving platform 203 moves away from the protective cover 306. The transmission rod 302 swings and pulls the protective cover 306 to move upward along the limit frame 303. At this time, the protective cover 306 opens, and the scanner below is exposed, allowing free scanning operations.

[0030] In an optional embodiment, the control switch 4 is electrically connected to the control switch 4.

[0031] In an optional embodiment, the mobile cabinet 1 is equipped with casters at all four corners below.

[0032] The working principle of this utility model is as follows: When using this device, the output end of the drive motor 207 simultaneously drives the first bevel gear 208 to rotate. The first bevel gear 208 meshes with the second bevel gear 209 on the moving platform 203, transmitting power to the second bevel gear 209. When the second bevel gear 209 rotates, it directly drives the rotating seat 205 to rotate around its own axis. The scanner installed on the rotating seat 205 rotates with the rotating seat 205, enabling multi-angle scanning of the outside world, reducing scanning blind spots, realizing composite scanning while moving and rotating, and greatly improving scanning efficiency and coverage.

[0033] The output of the drive motor 207 simultaneously drives the first bevel gear 208 to rotate. The first bevel gear 208 meshes with the second bevel gear 209 on the moving platform 203, transmitting power to the second bevel gear 209. When the second bevel gear 209 rotates, it directly drives the rotating seat 205 to rotate around its own axis. The scanner mounted on the rotating seat 205 rotates with the rotating seat 205, enabling multi-angle scanning of the outside world, reducing blind spots, and achieving composite scanning while moving and rotating, greatly improving scanning efficiency and coverage.
