Description

Technical Field

[0001] This utility model relates to the field of blue light scanning equipment technology, specifically a three-dimensional blue light automatic scanning equipment. Background Technology

[0002] A 3D blue light automatic scanning instrument, also known as a blue light 3D scanner or blue light scanner, is a high-precision, high-resolution 3D dimension measurement device. It projects a blue laser beam or blue light source onto the surface of an object, uses the reflected light to scan and measure its 3D contours, and then processes the data to obtain a 3D data model of the object.

[0003] For example, a 3D blue light scanning robot for inspecting workpiece quality, disclosed in Chinese Patent Publication No. CN109059804A, includes a 3D blue light scanner and a driving mechanism for driving the 3D blue light scanner to scan in multiple directions. The driving mechanism includes a horizontal moving mechanism for driving the 3D blue light scanner to move horizontally; a lifting moving mechanism for driving the 3D blue light scanner to move vertically; and a driving turntable located between the horizontal moving mechanism and the lifting moving mechanism. The lifting moving mechanism is located on the driving turntable, and the driving turntable is used to drive the 3D blue light scanner to rotate. The 3D blue light scanner is mounted on the lifting moving mechanism.

[0004] Existing 3D blue light automatic scanning machines cannot scan objects from multiple angles because the scanning head can only scan at a fixed angle. Therefore, an improved device is needed to address this problem. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 An embodiment of this utility model provides a three-dimensional blue light automatic scanning device, including a support device 1, a positioning device 2 fixedly installed at the top of the support device 1, a displacement device 3 slidably inserted into the top of the positioning device 2, the support device 1 including a drive motor 4, a support plate 5 and a positioning base plate 6, the drive motor 4 fixedly installed at the top center of the positioning base plate 6, the support plate 5 fixedly installed at the top center of the drive motor 4, the positioning device 2 including an arc frame 7, a connecting rod 8 and a hydraulic cylinder 9, the connecting rod 8 fixedly installed at the top of the hydraulic cylinder 9, and the arc frame 7 fixedly installed between the two connecting rods 8.

[0021] The displacement device 3 includes a plastic plate 10, a sleeve 11, a shaft 12, a scanning head 13, a displacement base plate 14, a top plate 15, and a threaded rod 16. The scanning head 13 is fixedly installed at the bottom end of the displacement base plate 14. The shaft 12 is rotatably installed at the top ends of both sides of the displacement base plate 14. The sleeve 11 is fixedly installed at the side end of the shaft 12 away from the displacement base plate 14. The top plate 15 is fixedly installed at the center of the top end of the displacement base plate 14. The plastic plate 10 is symmetrically slidably inserted into both sides of the top end of the displacement base plate 14. The threaded rod 16 is threaded through the top end of the top plate 15 and rotatably connected to the top end of the plastic plate 10. The displacement base plate 14 supports the scanning head 13 to rotate.

[0022] The machine shaft 12 is slidably inserted into the side end of the arc frame 7, and the hydraulic cylinder 9 is symmetrically fixedly installed on the top of the positioning base plate 6, which can adjust the overall height of the scanning head 13.

[0023] A plastic pad is fixedly installed on the top of the support plate 5. Rotation slots are provided on both sides and the top of the arc frame 7. The displacement base plate 14 and the machine shaft 12 can move in the rotation slots on the top and both sides of the arc frame 7, so that the displacement base plate 14 can be rotated and adjusted.

[0024] The top two sides of the displacement substrate 14 are provided with arc grooves, and the machine shaft 12 and the sleeve 11 are located inside the arc grooves. By having the arc grooves on both sides of the displacement substrate 14 fit against the outer surface of the arc frame 7, the displacement substrate 14 can be prevented from rotating when it rotates.

[0025] Movable grooves are provided on both sides of the top of the displacement substrate 14, and the plastic plate 10 is located inside the movable grooves. The movable grooves at the top of the displacement substrate 14 are vertically aligned with the tops of both sides of the arc frame 7, making it easy for the plastic plate 10 to dock with the arc frame 7.

[0026] Working Principle: In use, the object to be scanned is first placed on the top of the support plate 5. A plastic pad is fixedly installed on the top of the support plate 5 to prevent the object from sliding. Simultaneously, the scanning head 13 is turned on to detect the object on the support plate 5. The drive motor 4 is started, causing the support plate 5 to rotate, allowing the support plate 5 to rotate simultaneously with the object. This facilitates scanning different surfaces of the object by the scanning head 13, completing the scanning process. When using the scanning head 13, the hydraulic cylinder 9 can be activated, causing the connecting rod 8 to move up and down, adjusting the working height of the scanning head 13. Furthermore, the threaded rod 16 can be rotated, disengaging the plastic plate 10 from the arc frame 7, thus releasing the displacement base plate 14. The displacement base plate 14 is then rotated on the arc frame 7 until the scanning head 13 rotates. The scanning head 13 can be rotated to different angles to scan objects by moving the machine shaft 12 into the rotating grooves inside the arc frame 7 on both sides. The side end of the sleeve 11 near the displacement base plate 14 is in contact with the sides of the arc frame 7, which ensures that the scanning head 13 can rotate axially inside the arc frame 7. At the same time, the arc grooves on both sides of the displacement base plate 14 are in contact with the outer surface of the arc frame 7, which prevents the displacement base plate 14 from tilting during rotation and improves the stability of the scanning head 13 during rotation. Then, when the scanning head 13 rotates to the specified angle, the threaded rod 16 can be screwed and rotated until the plastic plate 10 passes through the top of the displacement base plate 14 and is fastened to the arc frame 7. This restricts the scanning head 13 to the specified angle for scanning, thus completing the work of scanning objects at different angles.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
