Description
Technical Field
[0001] This utility model relates to the field of scanning equipment technology, and in particular to a scanning device based on AR engraving. Background Technology
[0002] AR engraving is a technology that combines virtual digital models with physical processing in real time, guiding users or machines to perform precise engraving through AR devices. Its core process includes 3D scanning → AR virtual overlay → engraving execution. 3D scanning is the cornerstone of AR engraving technology, and its accuracy, speed, and data quality directly affect the matching effect between virtual modeling and physical engraving.
[0003] Currently, the stone carving industry mainly relies on handheld laser scanners to scan raw materials. These scanners use LiDAR or structured light sensors to scan the object's surface, combined with RGB cameras for texture capture, and generate 3D models in real time using SLAM (Simultaneous Localization and Mapping) algorithms. For small, non-standard, or temporary tasks, handheld scanning has the advantage of rapid deployment. However, for large objects or when high precision is required, handheld laser scanning is prone to shaking due to manual operation, leading to missing or distorted point cloud data, making it difficult to meet the millimeter-level carving requirements. On the other hand, large stones require the stitching of multiple sets of data, which easily introduces errors. The low efficiency and high error rate of existing handheld laser scanner technology seriously restrict the industrial application of AR carving.
[0004] Therefore, this application proposes an AR-based scanning device to solve the above problems. Utility Model Content
[0005] The present invention aims to overcome at least one of the defects (deficiencies) of the prior art and provide an AR-based scanning device to solve the technical problems of low efficiency and high error rate of existing handheld laser scanners.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a scanning device based on AR engraving, including an operating table, a horizontal adjustment mechanism and a support plate are provided above the operating table, a lifting adjustment mechanism is provided above the horizontal adjustment mechanism, a rotating mechanism is provided between the lifting adjustment mechanism and the horizontal adjustment mechanism, and a longitudinal adjustment mechanism is provided on the front side of the lifting adjustment mechanism.
[0007] The longitudinal adjustment mechanism includes a longitudinal adjustment plate and a longitudinal sliding frame. A limiting slide is provided on the longitudinal adjustment plate. Two auxiliary plates are fixedly connected to the upper end of the longitudinal adjustment plate. The two auxiliary plates are located on the front and rear sides of the limiting slide, respectively. A longitudinal adjustment motor is fixedly connected to the front end of the front auxiliary plate. The output end of the longitudinal adjustment motor passes through the front auxiliary plate and is fixedly connected to a longitudinal adjustment screw. The rear end of the longitudinal adjustment screw passes through the longitudinal sliding frame and is rotatably connected to the front end of the rear auxiliary plate. The longitudinal sliding frame is threadedly connected to the longitudinal adjustment screw. A laser scanner is fixedly connected to the lower end of the longitudinal sliding frame through the limiting slide and is located directly above the support plate.
[0008] The laser scanner is mounted on a vertical adjustment mechanism, which in turn is mounted on a lifting adjustment mechanism, which in turn is mounted on a rotation mechanism, which is mounted on a horizontal adjustment mechanism. These mechanisms together move the laser scanner along the X, Y, and Z axes. The rotation mechanism allows the lifting and vertical adjustment mechanisms, as well as the laser scanner itself, to be deflected, thus scanning the left and right sides of the material to be engraved. This scanning device uses mechanical control of the laser scanner, resulting in relatively stable movement. This solves the problem of missing or distorted point cloud data caused by shaking during scanning in traditional handheld scanning devices, thereby improving scanning accuracy.
[0009] Preferably, a position adjustment motor is fixedly connected to the lower end of the operating table. The output end of the position adjustment motor passes through the operating table and is fixedly connected to the lower end of the support plate. The upper end of the support plate is provided with several internal threaded grooves. Several support rods are provided above the support plate. The lower end of the support rods is adapted to the internal threaded grooves. The several support rods include at least two different axial length specifications.
[0010] In use, the material to be carved is placed on a support plate. The support rod connects to the threaded groove on the support plate to limit the position of the material and ensure its stability. The support rod is available in different lengths to suit different needs. The rotation mechanism can deflect the lifting adjustment mechanism, the longitudinal adjustment mechanism, and the laser scanner on the longitudinal adjustment mechanism, thereby scanning the left and right sides of the material to be carved. However, it cannot scan the front and rear sides. When the material to be carved is heavy, moving it is difficult. Therefore, the device also includes an adjusting motor and a support plate. The adjusting motor drives the support plate to rotate, causing the material to be carved, which is fixed on the support plate, to rotate as well. This allows the laser scanner to scan the front and rear sides of the material, achieving multi-directional scanning.
[0011] Preferably, the lifting adjustment mechanism includes a lifting frame, a lifting adjustment motor is fixedly connected to the upper end of the lifting frame, a lifting plate is slidably connected inside the lifting frame, the front end of the lifting plate is fixedly connected to the rear end of the longitudinal adjustment plate, the output end of the lifting adjustment motor passes through the upper side wall of the lifting frame and is fixedly connected to a lifting adjustment screw, the lower end of the lifting adjustment screw passes through the lifting plate and is rotatably connected to the lower inner wall of the lifting frame, and the lifting adjustment screw is threadedly connected to the lifting plate.
[0012] The lateral adjustment mechanism includes a lateral moving block, and a connecting groove is provided at the upper end of the lateral moving block;
[0013] The rotating mechanism includes a rotating plate, the upper end of which is fixedly connected to the lower end of the lifting frame. The lower end of the rotating plate extends into the connecting groove. A rotating rod is rotatably connected to the front inner wall of the connecting groove. The front end of the rotating rod passes through the rotating plate and the rear side wall of the connecting groove in sequence and is fixedly connected to a rotating worm gear.
[0014] The lifting adjustment motor drives the lifting adjustment screw to rotate, causing the lifting plate, which is threadedly connected to the screw, to move up and down, thus achieving lifting. Since the longitudinal adjustment mechanism is connected to the lifting plate, and the laser scanner is mounted on the longitudinal adjustment mechanism, the scanner can be lifted and lowered.
[0015] The lower end of the lifting frame is fixedly connected to the upper end of the rotating plate. When the rotating plate rotates, it can drive the lifting adjustment mechanism, the longitudinal adjustment mechanism, and the laser scanner set on the longitudinal adjustment mechanism to deflect left and right, thereby scanning the left and right sides of the material to be carved.
[0016] The rotating plate is connected to the lateral moving block. When the lateral moving block moves, it can drive the rotating mechanism to move laterally, thereby causing the lifting mechanism, the longitudinal adjustment mechanism, and the laser scanner mounted on the longitudinal adjustment mechanism to move laterally.
[0017] Preferably, the rotating rod is rotatably connected to the rear side wall of the connecting groove, the rotating rod is fixedly connected to the rotating plate, and an upper auxiliary plate and a lower auxiliary plate are fixedly connected to the rear end of the transverse moving block. The upper and lower auxiliary plates are located on the upper and lower sides of the rotating worm wheel, respectively. A rotating motor is fixedly connected to the upper end of the upper auxiliary plate, and the output end of the rotating motor passes through the upper auxiliary plate and is fixedly connected to a rotating worm. The lower end of the rotating worm is rotatably connected to the upper end of the lower auxiliary plate, and the rotating worm and the rotating worm wheel cooperate with each other.
[0018] When the rotary motor is working, it drives the rotary worm to rotate. The rotary worm meshes with the rotary worm wheel, thereby driving the rotary worm wheel to rotate, causing the rotary plate connected to it to rotate.
[0019] Preferably, the lateral adjustment mechanism further includes an auxiliary plate, and two auxiliary plates are provided. Both auxiliary plates are fixed on the operating table. A lateral movement motor is fixedly connected to the left end of the left auxiliary plate. The output end of the lateral movement motor passes through the right auxiliary plate and is fixedly connected to a lateral movement screw. The right end of the lateral movement screw passes through a lateral movement block and is rotatably connected to the left end of the right auxiliary plate. The lateral movement screw is threadedly connected to the lateral movement block.
[0020] The lateral moving screw rotates under the drive of the lateral moving motor, causing the lateral moving block threaded to it to move laterally along the screw.
[0021] Preferably, a limiting slide rod is fixedly connected to the right end of the auxiliary plate on the left side. The right end of the limiting slide rod passes through the transverse moving block and is fixedly connected to the left end of the auxiliary plate on the right side. The limiting slide rod is slidably connected to the transverse moving block.
[0022] When the lateral moving screw rotates, the lateral moving block, which is threaded to it, may rotate with the screw due to friction, thus preventing lateral movement. Setting a limit slide bar can restrict the lateral moving block from rotating with the lateral moving screw, thereby enabling lateral movement.

Mechanical scanning can solve the problems of point cloud data loss or distortion caused by shaking during scanning of traditional manual handheld scanning equipment, the inability to meet the millimeter-level engraving requirements and the low efficiency.
[0025] 2. This utility model provides a scanning device based on AR engraving. The device utilizes a horizontal adjustment mechanism, a vertical adjustment mechanism, and a lifting adjustment mechanism to enable the laser scanner to adapt to the scanning of materials of different sizes. Compared with traditional manual scanning equipment, this device has stronger adaptability.
[0026] 3. This utility model provides a scanning device based on AR engraving. In this device, the internal thread groove above the support plate cooperates with the support rod to meet the support of engraving materials of different shapes, ensuring that the position of the material is fixed, thereby effectively avoiding the scanning blind zone caused by the clamping of materials by traditional complex fixtures.
