DETAILED DESCRIPTION

[0024] In order for those skilled in the art to better understand the present application, the technical scheme of the present application is further described below in combination with the drawings and embodiments.

[0025] Embodiment 1

[0026] like Figure 1 As shown, an automated 3D modeling and scanning device includes a fixed base 1. A support platform 2 is integrally formed on the upper end of the fixed base 1. Several grooves 21 are evenly distributed on the side of the support platform 2. Electromagnetic drive structures are installed inside the support platform 2 on both sides of the grooves 21. A sliding support ring 3 is movably installed on the outside of the support platform 2 via the grooves 21 and the electromagnetic drive structures. An electromagnetic slider, which slides up and down in conjunction with the electromagnetic drive structures, is integrally formed on the inner side of the sliding support ring 3 at the grooves 21. A main scanning plate 5 is movably installed on the outside of the sliding support ring 3 via several flaring mechanisms 4. Figure 4 As shown, several main scanning plates 5 are arc-shaped plates, and several main scanning plates 5 are combined to form a small circular scanning ring. Both ends of several main scanning plates 5 have arc-shaped slots 51. Sub-scanning plates 6 are elastically installed in the arc-shaped slots 51 through pressure springs 52. Two sub-scanning plates 6 between two adjacent main scanning plates 5 are in contact through pressure springs 52. Scanning lamps 7 are embedded in the inner sides of several main scanning plates 5 and several sub-scanning plates 6. The upper end of the support platform 2 is set as a scanning platform, and several scanning lamps 7 scan up and down on the outside of the scanning platform.

[0027] The sub-scanning plates 6 are arc-shaped plates, and the center lines of the sub-scanning plates 6 and the center lines of the main scanning plates 5 are collinear.

[0028] After the sub-scanning plates 6 extend out, they are combined with the main scanning plates 5 to form a large circular scanning ring.

[0029] The length of several of the arc-shaped slots 51 is greater than the length of several scanning plates 6.

[0030] The flaring mechanism 4 includes several support columns 41, several push cylinders 43, and several movable rods 44. The support columns 41 are uniformly and integrally formed on the outside of the sliding support ring 3. The upper surface of the support columns 41 has a mounting groove 42. The push cylinders 43 are respectively installed in the mounting grooves 42. The push cylinders 43 extend and retract synchronously. The fixed ends of the push cylinders 43 are fixed on the outer surface of the sliding support ring 3. The driving ends of the push cylinders 43 are respectively connected to the inner side of the lower end of the movable rods 44. The inner side of the upper end of the movable rods 44 is installed in the middle of the outer side of the main scanning plate 5. The main scanning plate 5 is separated and merged inside and outside by the push cylinders 43.

[0031] like Figure 2 and Figure 3As shown, this invention achieves automatic flaring of objects from small to large diameter by controlling the extension and retraction of the push cylinder 43 in conjunction with the elasticity of the pressure spring 52. During flaring, the stroke of the drive end of several push cylinders 43 is controlled, thereby pushing the movable rod 44 to extend radially outward. The main scanning plate 5, which forms a small circular scanning ring, shifts outward coaxially. At the same time, the auxiliary scanning plates 6 at both ends of the main scanning plate 5 move away from each other, and the pressure spring 52 pops out the auxiliary scanning plates 6. The two auxiliary scanning plates 6 between two adjacent main scanning plates 5 are pushed out by the spring force and then pressed together to form a new large-diameter circular scanning ring. This process continues until the large-diameter circular scanning ring meets the diameter size of the part to be scanned, thus better meeting the 3D modeling and scanning needs of objects of different sizes. The structure is simple and highly automated.

[0032] The number of main scanning plates 5 is set to at least 4, the number of support columns 41, the number of push cylinders 43 and the number of movable rods 44 are set to 4, and the number of auxiliary scanning plates 6 are set to 8. The more main scanning plates 5 are set, the greater the stroke of the push cylinders 43, so that the circular scanning ring that the main scanning plates 5 and auxiliary scanning plates 6 can be spliced ​​can meet the scanning diameter of larger parts, and can adapt to more diameter parts for 3D modeling and scanning.

[0033] An adhesive layer 22 is embedded on the upper surface of the support platform 2 to prevent the bottom of the part from slipping and sticking, and to prevent the part from shaking in position and angle when the support platform 2 vibrates slightly, thus affecting the 3D modeling and scanning results.

[0034] The stroke of the pushing cylinder 43 satisfies the ejection stroke of the sub-scanning plates 6 after the main scanning plates 5 are deployed.

[0035] The electromagnetic drive structure drives the sliding support ring 3 up and down to meet the up and down scanning stroke of the scanning lamp 7 on the object.

[0036] This invention uses an electromagnetic drive structure to perform up-and-down scanning, and the main scanning plate 5 and the auxiliary scanning plate 6 are assembled into a complete circular scanning ring. The flaring stroke of the cylinder 43 and the up-and-down scanning stroke of the electromagnetic drive structure are both matched with the diameter of the circular scanning ring formed by the main scanning plate 5 and the auxiliary scanning plate 6. The scanning light plate 7 does not need to rotate to achieve overall scanning, thus improving the accuracy of scanning the side of the part.

[0037] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
