Technical Field

[0001] The present invention relates to the technical field of three-dimensional scanning, and in particular to an automatic scanning device for three-dimensional models. Background Art

[0002] 3D model scanning refers to the process of obtaining the geometric shape and spatial position information of an object's surface by using 3D scanning technology, and then creating a 3D digital model of the object; and a scanning device is usually required during 3D scanning.

[0003] In the prior art, a patent with application number CN202420317225.9 discloses a fully automatic 3D scanning device, which only needs to place the object to be tested on a rotating boss, take photos of the object to be tested at various angles after several rotations, and upload them to the background, and then generate 3D model data of the object to be tested by using the model in the background. However, in the actual scanning process, the top and bottom of the object may contain important supporting structures or features. Especially in some objects with complex structures or special shapes, the details of the top and bottom may be crucial to the overall understanding of the structure and function of the object. However, when the 3D scanning device is in use, it can only scan and shoot the side of the object, but cannot scan the top and bottom of the object, which may easily lead to the omission of important information and the inability to accurately obtain the complete 3D model of the object. For this reason, the present invention discloses an automatic 3D model scanning device to meet people's needs. Summary of the invention

[0022] Example: Reference Figure 1-Figure 4 The three-dimensional model automatic scanning device shown in the figure includes a scanning cabinet 1, the front part of the scanning cabinet 1 is rotatably connected to two matching protective cabinet doors 25, a fixed partition 2 is fixedly arranged in the scanning cabinet 1, a servo motor 3 is fixedly arranged on the bottom inner wall of the scanning cabinet 1, a supporting shaft 4 is fixedly installed on the output end of the servo motor 3, the top of the supporting shaft 4 passes through the fixed partition 2 and is fixedly installed with a transparent placement plate 5, a first rotating hole is opened on the top of the fixed partition 2, a vertical screw 6 is rotatably installed in the first rotating hole, a synchronous transmission unit for driving the vertical screw 6 to rotate synchronously is connected to the supporting shaft 4, a vertical moving block 7 is threadedly sleeved on the vertical screw 6, mounting plates 8 are fixedly installed on the top of the fixed partition 2 and the top inner wall of the scanning cabinet 1, and the sides of the two mounting plates 8 are opened with second Two rotating holes, horizontal screws 9 are rotatably installed in the two second rotating holes, and a lower block 10 and an upper block 11 are respectively threadedly sleeved on the two horizontal screws 9. Scanning heads 12 are fixedly provided on the side of the vertical moving block 7, the top of the lower moving block 10 and the bottom of the upper moving block 11. Two active bevel gears 13 are fixedly sleeved on the vertical screw 6, and one end of the two horizontal screws 9 is fixedly installed with a driven bevel gear 14, and the two active bevel gears 13 are respectively meshed with the two driven bevel gears 14. A vertical guide rail 17 is fixedly installed on the inner wall of the side of the scanning cabinet 1, and the vertical moving block 7 is slidably installed on the vertical guide rail 17. Horizontal guide rails 18 are fixedly installed on the top of the fixed partition 2 and the inner wall of the top of the scanning cabinet 1, and the lower block 10 and the upper block 11 are respectively slidably installed on the two horizontal guide rails 18.

[0023] By means of the above structure, when in use, the object can be placed on the transparent placement plate 5 first, then the protective cabinet door 25 is closed and the servo motor 3 is started. The operation of the servo motor 3 will drive the support shaft 4 to rotate. The rotation of the support shaft 4 can drive the transparent placement plate 5 and the object to rotate together. In this process, the rotation of the support shaft 4 will also drive the vertical screw 6 to rotate synchronously through the synchronous transmission unit. Under the cooperation of the vertical guide rail 17, the rotation of the vertical screw 6 will drive one of the scanning heads 12 to move up and down through the vertical moving block 7. At the same time, the rotation of the vertical screw 6 will also drive the two horizontal screws 9 to rotate together through the active bevel gear 13 and the driven bevel gear 14. Under the cooperation of the horizontal guide rail 18, the rotation of the two horizontal screws 9 will drive the other two scanning heads 12 to move horizontally through the lower moving block 10 and the upper moving block 11, thereby realizing automatic all-round scanning and shooting of the side, bottom and top surfaces of the object, thereby effectively reducing the situation where important information is missed and the complete three-dimensional model of the object cannot be accurately obtained, ensuring the accuracy of the scanning result, and the use is simple and convenient, and the practicability is good.

[0024] like Figure 3 As shown, the synchronous transmission unit includes two transmission pulleys 15 respectively fixedly sleeved on the support shaft 4 and the vertical screw 6, and a transmission belt 16 is tensioned on the two transmission pulleys 15. When the support shaft 4 rotates, it will drive one of the transmission pulleys 15 to rotate, and at this time, under the action of the transmission belt 16, it will drive the other transmission pulley 15 to rotate together, and then drive the vertical screw 6 to rotate synchronously, playing a transmission role.

The anti-skid unit includes a support plate 22 fixedly installed on the side of the scanning cabinet 1, and a threaded hole is provided on the top of the support plate 22. A moving stud 23 is threadedly installed in the threaded hole, and an anti-skid plate 24 is fixedly installed on the bottom end of the moving stud 23. When the moving stud 23 is rotated, under the joint action of the threaded hole, the moving stud 23 can move up and down while rotating, and then the anti-skid plate 24 can be driven to move up and down together. When the anti-skid plate 24 is moved upward to leave the ground, the device can be directly pushed to move and adjust its position. When the anti-skid plate 24 is moved downward to conflict with the ground, the friction between the device and the ground can be effectively increased, so that the device can be stably placed on the ground for use, not easy to shake, and has good stability.
