Description

Technical Field

[0001] This utility model relates to the field of 3D scanner accessories technology, and in particular to a 3D scanner calibration mechanism. Background Technology

[0002] A 3D scanner is a device used to capture the geometry and texture of an object's surface, generating a three-dimensional digital model of the object. It is widely used in many fields such as industrial design, reverse engineering, medicine, cultural relic preservation, and entertainment.

[0003] Currently, scanning jobs in non-studio settings, such as outdoor and indoor scanning, are mostly done manually using handheld 3D scanners. While this process can meet basic scanning needs and is convenient to operate;

[0004] However, in actual scanning operations, due to the lack of auxiliary calibration mechanisms, manual hand-held scanning will inevitably produce large deviations during movement, resulting in low overlap of manual scanning results and ultimately unreliable scanning data. If a professional guide rail auxiliary mechanism is used, it is not only bulky but also requires systematic assembly, making it impractical to carry around. Therefore, there is an urgent need for a 3D scanner calibration mechanism. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a 3D scanner calibration mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A 3D scanner calibration mechanism includes an arc-shaped base one and an arc-shaped base two, which are spliced ​​together to form a semi-circular base. Arc-shaped guide rods are provided on both arc-shaped base one and arc-shaped base two to assemble connecting seats. The connecting seats are used to assemble the scanner body.

[0008] The bottom of the connector has a limiting groove to mate with the arc-shaped guide rod, and the upper part of the connector is equipped with a mounting base. A rotating disk is rotatably mounted on the upper part of the mounting base, and the rotating disk is used to assemble the scanner body.

[0009] A guide rod is installed on one side of the upper part of the connecting seat, and a screw is installed on the other side via a turntable. Both the guide rod and the screw are connected to the mounting seat. When the turntable drives the screw to rotate, the mounting seat moves vertically by rotating the screw.

[0010] Furthermore, in a preferred configuration, the first arc-shaped seat and the second arc-shaped seat are connected by a hinge.

[0011] In addition, a preferred structure is that a snap-fit ​​groove is provided on one side of the arc-shaped seat one, and the snap-fit ​​groove is used to connect with a snap-fit ​​block provided on one side of the arc-shaped seat two.

[0012] In addition, a preferred structure is that the outer wall of the arc-shaped guide rod is symmetrically provided with a pair of grooves, which are used to engage with the balls provided on the inner wall of the limiting groove. The balls are limited and rolled on the inner wall of the limiting groove through the ball groove.

[0013] In addition, a preferred structure is that the bottom of the turntable is rotatably connected to the connecting seat, and a screw is provided at the middle of the upper end of the turntable, which is screwed to the mounting seat.

[0014] In addition, a preferred configuration is that a hand handle is provided on one side of the rotating disk.

[0015] Furthermore, a preferred configuration is that the upper part of the rotating disk is provided with universal fittings for assembling the scanner body.

[0016] The beneficial effects of this utility model are as follows:

[0017] I. In this utility model, arc-shaped base one and arc-shaped base two are spliced ​​together to form an auxiliary calibration base for the scanner body. The scanner body can perform precise rotation scanning through the arc-shaped base, and the height of the scanner body can be easily adjusted by setting up components such as turntables and screws, so as to ensure the auxiliary calibration effect and improve scanning accuracy and efficiency.

[0018] Second, in this utility model, the assembly and splicing function of the arc-shaped seat assembly is realized by setting components such as hinges, snap-fit ​​blocks, and snap-fit ​​slots, which reduces the carrying volume of the overall auxiliary calibration mechanism, improves carrying convenience, and thus ensures the scanning efficiency of the scanner.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-6 A 3D scanner calibration mechanism includes an arc-shaped base 1 and an arc-shaped base 2. The arc-shaped base 1 and the arc-shaped base 2 are spliced ​​together to form a semi-circular base. Arc-shaped guide rods 3 are provided on both the arc-shaped base 1 and the arc-shaped base 2 to assemble connecting seats 4. The connecting seats 4 are used to assemble the scanner body 5.

[0028] Furthermore, a limiting groove 17 is provided at the bottom of the connecting seat 4 to mate with the arc-shaped guide rod 3, and a mounting seat 6 is installed on the upper part of the connecting seat 4. A rotating disk 7 is rotatably installed on the upper part of the mounting seat 6. The rotating disk 7 is used to assemble the scanner body 5.

[0029] Furthermore, a guide rod 16 is installed on one side of the upper part of the connecting seat 4, and a screw 15 is installed on the other side via a turntable 14. Both the guide rod 16 and the screw 15 are connected to the mounting seat 6. When the turntable 14 drives the screw 15 to rotate, the mounting seat 6 moves vertically by rotating the screw.

[0030] Arc-shaped base 1 and arc-shaped base 2 are connected by hinge 12, which enables relative rotation between arc-shaped base 1 and arc-shaped base 2 for storage and assembly.

[0031] A snap-fit ​​groove 10 is provided on one side of the arc-shaped seat 1. The snap-fit ​​groove 10 is used to connect with the snap-fit ​​block 11 provided on one side of the arc-shaped seat 2. The stability of the arc-shaped seat 1 and the arc-shaped seat 2 after splicing and assembly is improved by the snap-fit ​​groove 10 and the snap-fit ​​block 11.

[0032] The outer wall of the arc-shaped guide rod 3 is symmetrically provided with a pair of grooves. The grooves are used to connect with the balls 13 set on the inner wall of the limiting groove 17. The balls 13 are set on the inner wall of the limiting groove 17 by the ball groove for limiting and rolling, which improves the movement stability.

[0033] The bottom of the turntable 14 is rotatably connected to the connecting seat 4, and a screw 15 is provided at the middle of the upper end of the turntable 14. The screw 15 is screwed to the mounting seat 6.

[0034] A hand lever 8 is provided on one side of the rotating disk 7, which facilitates operation by personnel.

[0035] The upper part of the rotating disk 7 is provided with a universal fitting 9 for mounting the scanner body 5.

[0036] In this embodiment, the connecting seat 4 is installed onto the arc guide rod 3 set on any arc seat. Then, the arc seat 1 and arc seat 2 are unfolded and connected by the snap-fit ​​groove 10 and snap-fit ​​block 11. At this time, the arc guide rods 3 are connected to each other to form an integral semi-circular guide rod.

[0037] The ball bearing 13 enables the connecting seat 4 to move, and the rotating turntable 14 drives the screw 15 to rotate, thereby driving the mounting seat 6 to move up and down to change the overall scanning height of the scanner body 5.

[0038] In practical applications, the scanner body 5 is installed in the auxiliary calibration mechanism using the universal assembly 9. The scanner body 5 can be rotated or moved along the arc-shaped guide rod 3 by the hand lever 8. This not only makes the operation convenient but also ensures a stable scanning process, effectively improving scanning accuracy and efficiency.
