Detailed Implementation

[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this invention as detailed in the appended claims.

[0035] In the process of big data collection, 3D scanning equipment serves as an important tool, enabling precise scanning of three-dimensional objects and rapid acquisition of various data. This data is crucial for training AI models and optimizing algorithm performance.

[0036] However, existing 3D scanning equipment typically requires manual adjustment of the angle of the object being scanned. This manual operation not only increases labor intensity but also significantly reduces efficiency during large-scale data acquisition. Furthermore, manual adjustments can lead to scan inconsistencies, affecting the integrity and accuracy of the data.

[0037] In view of this, the present invention provides a three-dimensional scanning device. By setting a rotating unit, the object to be scanned on the stage and the scanner rotate relative to each other, reducing manual intervention in the scanning process. This not only improves scanning efficiency but also enhances scanning continuity, thereby improving the integrity and accuracy of the scanned data.

[0038] The technical solution of this utility model and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0039] refer to Figures 1 to 4This utility model provides a three-dimensional scanning device 100, which may include a base 110, a stage 120, a scanning unit 130, and a rotating unit 140.

[0040] The base 110 provides a stable support structure for the entire device, ensuring that the device remains stable during operation. The stage 120 is located on the base 110 and is suitable for carrying the object to be scanned; in other words, the object to be scanned is placed on the stage 120 for scanning.

[0041] The scanning unit 130 may include a scanner 131 and an adjustment device 132. The adjustment device 132 is disposed on the base 110, and the scanner 131 is disposed on the adjustment device 132. The scanner 131 is responsible for scanning and capturing the three-dimensional data of the object to be scanned, while the adjustment device 132 is used to adjust the scanning position of the scanner 131. The scanning position of the scanner 131 may include the scanning angle of the scanner 131 relative to the object to be scanned and the scanning height of the scanner 131. Alternatively, in some embodiments, the scanning position of the scanner 131 may also include the distance between the scanner 131 and the object to be scanned.

[0042] A rotating unit 140 is driven to either a stage 120 or a scanning unit 130, such that one of the stage 120 or the scanning unit 130 rotates relative to the other. Exemplarily, the rotating unit 140 can be driven to rotate the stage 120, causing the stage 120 and the object to be scanned on it to rotate. During this rotation, the scanner 131 facing the stage 120 scans and captures the three-dimensional data of the object. Alternatively, the rotating unit 140 can be driven to rotate the scanning unit 130 around the stage 120, and during this rotation, the scanner 131 facing the stage 120 scans and captures the three-dimensional data of the object.

[0043] The three-dimensional scanning device 100 of this invention first adjusts the scanning position of the scanner 131 via the adjustment device 132 during the scanning process to facilitate scanning the outline of the object to be scanned. Then, the rotating unit 140 causes the object to be scanned on the stage 120 to rotate relative to the scanner 131, reducing manual intervention in the scanning process. This improves both scanning efficiency and scanning continuity, thereby enhancing the integrity and accuracy of the scanned data.

[0044] refer to Figure 1 , Figure 2 and Figure 3In some embodiments, the adjustment device 132 may include a mounting bracket 1321, a first adjustment component 1322, and a second adjustment component 1323. The scanner 131 is movably mounted on the mounting bracket 1321 via the first adjustment component 1322. The mounting bracket 1321 provides stable support for the scanner 131 to ensure that the scanner 131 remains stable during adjustment and to reduce scanning errors caused by vibration during scanning. The mounting bracket 1321 is mounted on the base 110 via the second adjustment component 1323.

[0045] The first adjustment component 1322 is adapted to adjust the scanning angle of the scanner 131. For example, the first adjustment component 1322 can be a pivot-type adjustment structure to adjust the pitch scanning angle of the scanner 131 relative to the object to be scanned on the stage 120. Alternatively, the first adjustment component 1322 can also be a composite adjustment structure, which can simultaneously have a structure for adjusting the pitch angle of the scanner 131 and a structure for adjusting the circumferential angle of the scanner 131 relative to the object to be scanned. This allows the scanner 131 to more comprehensively cover all surfaces of the object to be scanned, reducing blind spots and improving the integrity and accuracy of the scanned data.

[0046] The second adjustment component 1323 is adapted to adjust the height of the mounting bracket 1321. Exemplarily, the second adjustment component 1323 may include an electrically operated telescopic device, such as an electrically operated telescopic rod or an electrically operated telescopic cylinder. The second adjustment component 1323 may also include a pneumatic telescopic device, or of course, a hydraulic lifting device. The height adjustment function of the second adjustment component 1323 enables the 3D scanning device 100 to adapt to scanning objects of different heights, enhancing the applicability and flexibility of the 3D scanning device 100, reducing the need for manual adjustment of objects, and improving operational efficiency.

[0047] Thus, the adjustment device 132 provides the scanning unit 130 with a high degree of flexibility and adaptability, enabling the 3D scanning device 100 to maintain efficient and accurate performance under different scanning conditions. This design not only improves scanning efficiency but also ensures the integrity and accuracy of data acquisition, making it suitable for a variety of complex scanning tasks and application scenarios.

[0048] refer to Figure 1 and Figure 4 According to some embodiments of the present invention, the base 110 may include a first support portion 111 and a second support portion 112 distributed horizontally. The stage 120 is disposed on the first support portion 111. By providing a solid support for the stage 120, the first support portion 111 ensures that the object to be scanned remains stable during the scanning process, reducing scanning errors caused by vibration or displacement.

[0049] The second support portion 112 defines the installation space. The second adjustment assembly 1323 includes a telescopic device, which is located in the installation space, and the telescopic end of the telescopic device is connected to the mounting frame 1321. This ensures that the telescopic device is not disturbed by external factors during adjustment, which helps to extend the service life of the telescopic device. For example, the telescopic device may include an electric telescopic device (electric telescopic rod, electric telescopic cylinder), a pneumatic telescopic device, or a hydraulic telescopic device.

[0050] Thus, through the distributed design of the base 110, the 3D scanning device 100 is not only more structurally robust but also more functionally flexible. This design ensures that the 3D scanning device 100 maintains high efficiency and accuracy under various scanning conditions, making it suitable for a variety of complex application scenarios.

[0051] refer to Figure 1 According to some embodiments of the present invention, a portion of the structure of the mounting bracket 1321 protrudes toward the base 110 to form a protective sleeve 1321a. The protective sleeve 1321a is fitted onto the outside of the second bearing portion 112. The protective sleeve 1321a provides additional protection for the telescopic device inside the second bearing portion 112, preventing damage from the external environment and extending the service life of the device.

[0052] The sheath 1321a is slidable relative to the second support part 112. Thus, during the process of adjusting the scanning height of the scanner 131 by starting the telescopic device, the sheath 1321a slides along the outer wall of the second support part 112, which plays a certain guiding role and helps to improve the accuracy of the scanner 131 lifting process, thereby improving the structural reliability of the three-dimensional scanning device 100.

[0053] refer to Figure 1 , Figure 2 and Figure 3 According to some embodiments of this utility model, the first adjustment component 1322 includes a first rotating shaft 13221, a locking structure 13222, and a mating structure 13223. The scanner 131 is fixedly connected to the first rotating shaft 13221. The mounting bracket 1321 includes two arm plates 1321b that are axially opposite each other along the first rotating shaft 13221, and both ends of the first rotating shaft 13221 pass through the two arm plates 1321b respectively. By rotating the first rotating shaft 13221, the scanner 131 can scan at different angles, providing a more comprehensive coverage area, reducing blind spots, and improving the integrity of the scanned data.

[0054] A locking structure 13222 is disposed on one of the first rotating shaft 13221 and the arm plate 1321b, and a mating structure 13223 is disposed on the other. The locking structure 13222 and the mating structure 13223 are locked together, so that the first rotating shaft 13221 is locked relative to the mounting bracket 1321. For example, the locking structure 13222 can be disposed on the first rotating shaft 13221, and the mating structure 13223 can be disposed on the arm plate 1321b. Alternatively, the locking structure 13222 can also be disposed on the arm plate 1321b, and the mating structure 13223 can be disposed on the first rotating shaft 13221. After the first rotating shaft 13221 is rotated to the position (i.e., the scanner 131 is adjusted to a suitable scanning angle), the locking structure 13222 and the mating structure 13223 are locked together, so that the first rotating shaft 13221 and the mounting bracket 1321 are relatively fixed. This ensures that the first rotating shaft 13221 can be stably held in the position after being adjusted to the required angle, preventing angular deviation caused by vibration or other external forces during scanning, thereby improving the accuracy and stability of scanning.

[0055] Thus, through the design of the first adjustment component 1322, the 3D scanning device 100 achieves flexible adjustment and stable locking of the scanner 131 angle. This design not only improves the flexibility and accuracy of scanning but also ensures stability and reliability under various operating conditions.

[0056] refer to Figure 3 According to some embodiments of the present invention, the locking structure 13222 includes a gear ring 13222a, which is fixedly connected to the first rotating shaft 13221. The peripheral wall of the gear ring 13222a is provided with a plurality of locking teeth 13222b. The design of the gear ring 13222a provides a plurality of locking positions, which enables the first rotating shaft 13221 to achieve precise locking, which is beneficial to improving the flexibility and accuracy of the angle adjustment of the scanner 131.

[0057] The mating structure 13223 includes a locking block 13223a, which is disposed on the arm plate 1321b. The locking block 13223a is movably inserted between the locking teeth 13222b so that the first rotating shaft 13221 is locked in place with the mounting bracket 1321. For example, the locking block 13223a can be inserted into the arm plate 1321b and slide in a direction parallel to the first axis. The locking block 13223a may include a sliding part and a locking part. The projection of the sliding part in the projection plane is outside the outline of the projection of the gear ring 13222a. The projection of the locking part in the projection plane coincides with the projection of the gear ring 13222a. The projection plane coincides with the axis of the first rotating shaft 13221. During the sliding process of the locking block 13223a, the locking part is engaged between the locking teeth 13222b, so that the first rotating shaft 13221 is fixed relative to the mounting bracket 1321. Alternatively, the locking part disengages from between the locking teeth 13222b, and the first rotating shaft 13221 is unlocked from the mounting bracket 1321. Alternatively, the locking block 13223a can be connected to an elastic device, which causes the locking block 13223a to move radially along the first rotating shaft 13221, thereby causing the locking hole to be inserted between the locking teeth 13222b to complete the locking, or to disengage from between the locking teeth 13222b to unlock the first rotating shaft 13221.

[0058] The locking block 13223a can be inserted between different locking teeth 13222b to quickly and reliably fix the first rotating shaft 13221 at the required angle position, preventing angle deviation caused by external force during scanning.

[0059] According to some embodiments of this utility model, the arm plate 1321b is provided with an arc-shaped spring piece 13223b, the center of curvature of which coincides with the axis of the gear ring 13222a, and the locking block 13223a is fixedly connected to the arc-shaped spring piece 13223b. On the one hand, the arc-shaped spring piece 13223b can provide a moderate elastic force when the locking block 13223a is inserted into and pulled out of the locking teeth 13222b. This helps to ensure that the locking block 13223a smoothly enters or exits between the locking teeth 13222b, improving the smoothness of the locking and unlocking process of the first rotating shaft 13221. On the other hand, the arc-shaped spring piece 13223b also allows the locking block 13223a to obtain additional elastic support when inserted into the locking teeth 13222b, ensuring the stability of the locking block 13223a in the locked position. Meanwhile, the elastic properties of the arc-shaped spring 13223b allow the locking block 13223a to be quickly and easily pulled out of the locking teeth 13222b, enabling rapid angle adjustment.

[0060] Furthermore, there can be multiple locking blocks 13223a. Multiple locking blocks 13223a are disposed on the surface of the arc-shaped spring piece 13223b facing the toothed ring 13222a. The spacing between two adjacent locking blocks 13223a matches the size of the locking teeth 13222b. In this way, when locking the first rotating shaft 13221, the locking effect is better by the cooperation of multiple locking blocks 13223a, which helps to improve the stability of the scanner 131 during the scanning process and thus improves the accuracy of the scanning results.

[0061] Furthermore, the mating structure 13223 can be configured as two, with the two mating structures 13223 arranged radially opposite each other along the first rotating shaft 13221, thereby improving the locking effect on the first rotating shaft 13221, preventing the scanner 131 from shaking during the scanning process, and improving the structural reliability of the three-dimensional scanning device 100.

[0062] According to some embodiments of this utility model, an adjusting member 1324 is detachably provided on the first rotating shaft 13221. The adjusting member 1324 provides a convenient manual adjustment interface, allowing the user to easily adjust the scanning angle of the scanner 131. The adjusting member 1324 can be a knob or a handle.

[0063] For example, the adjusting member 1324 can be detachably installed on the first rotating shaft 13221 by insertion, or the adjusting member 1324 can be threadedly connected to the first rotating shaft 13221.

[0064] Thus, the detachable design of the adjustment component 1324 allows users to quickly install or remove it as needed, thereby flexibly adjusting the angle of the scanner 131. Using the adjustment component 1324, users can more precisely control the positioning of the scanner 131, improving operational flexibility and accuracy. At the same time, the detachability of the adjustment component 1324 also facilitates equipment maintenance and replacement.

[0065] refer to Figure 1 and Figure 4 According to some embodiments of this utility model, the rotating unit 140 includes a drive motor 141, which is fixedly mounted on the first bearing part 111. The output end of the drive motor 141 is connected to a drive gear 142. The first bearing part 111 defines a mounting cavity, in which a rotatable driven gear 143 is disposed, meshing with the drive gear 142. The platform 120 is fixedly connected to the driven gear 143. Exemplarily, the platform 120 may be located above the driven gear 143, and the platform 120 may be welded to the driven gear 143. Alternatively, the platform 120 may be fixedly connected to the driven gear 143 by bolts or other fasteners.

[0066] Thus, the drive motor 141 provides a stable and controllable power source for the rotating unit 140, ensuring that the stage 120 can rotate smoothly. Furthermore, through the precise control of the drive motor 141, users can achieve precise adjustment of the rotation speed and angle, improving the flexibility and accuracy of the scanning process.

[0067] According to some embodiments of this utility model, the rotating unit 140 may further include a reduction gear 144. The output end of the drive motor 141 is connected to the input end of the reduction gear 144, and the output end of the reduction gear 144 is connected to the drive gear 142. The reduction gear 144 achieves precise control of the rotation speed of the stage 120 by reducing the output speed of the drive motor 141 while increasing the output torque. This improves the stability and accuracy of the rotation process, while reducing the load on the drive motor 141 and extending its service life. The reduction gear 144 enables the stage 120 to rotate at a smoother speed, reducing vibration and noise caused by rapid rotation, and improving the smoothness of the scanning process and the accuracy of data acquisition.

[0068] According to some embodiments of the present invention, the rotating unit 140 may further include a protective cover 145, which is disposed on the outside of the drive motor 141. The protective cover 145 provides physical protection for the drive motor 141, preventing dust, liquid or other external environmental factors from affecting the drive motor 141, which is beneficial to extending the service life of the drive motor 141 and reducing failures and maintenance needs caused by environmental factors.

[0069] The protective cover 145 is detachably connected to the base 110. Exemplarily, the protective cover 145 can be snapped onto the base 110, or it can be mounted on the base 110 with screws, or it can be threaded onto the base 110. This detachable design allows the user to easily remove the protective cover 145 when maintenance or repair of the drive motor 141 or other internal components is required, reducing maintenance time and complexity and improving the maintainability of the equipment.
