Description

Technical Field

[0001] This utility model relates to the field of scanner technology, and in particular to a three-dimensional scanner with an adjustable scanning angle. Background Technology

[0002] A 3D scanner is a device used to capture the shape and structure of an object's surface, and it is widely used in industrial design, reverse engineering, cultural relic preservation, medical imaging, virtual reality, and other fields. 3D scanning technology allows for the rapid acquisition of precise geometric data of objects and the generation of high-precision 3D models. With the development of modern industry and digital technology, different industries have placed higher demands on the functionality and performance of 3D scanners, such as scanning accuracy, adaptability, and efficiency. Especially when scanning objects with complex shapes and varying sizes, 3D scanners need to have the ability to flexibly adjust the scanning angle to capture complete detail data, ensuring the comprehensiveness and reliability of the 3D model.

[0003] Existing 3D scanners mostly employ fixed-angle or limited-angle scanning methods, which are insufficient to meet the scanning needs of complex shapes and objects of varying sizes. Fixed scanning angles easily lead to blind spots, resulting in the loss of crucial details and affecting the accuracy and integrity of the model. Furthermore, traditional 3D scanners often rely on manual operation or simple mechanical devices to adjust the scanning angle, a cumbersome process with insufficient precision, making efficient multi-angle and omnidirectional scanning difficult. Simultaneously, poor coordination between the transmission and moving mechanisms of the scanning device can easily lead to errors or instability during operation, thus reducing scan quality. Therefore, developing a 3D scanner with flexibly adjustable scanning angles and high-precision, omnidirectional scanning capabilities has become an urgent need in the field of 3D imaging technology.

[0032] like Figure 1-3 As shown, this utility model provides a technical solution: a three-dimensional scanner with an adjustable scanning angle, including: a support foot 1, a placement platform 2 fixedly connected to the upper end of the support foot 1, a bracket 3 fixedly connected to the upper end of the placement platform 2, and a movable mechanism 4 fixedly connected to one side of the upper end of the bracket 3.

[0033] The active mechanism 4 includes a connecting column 41 fixedly connected to one side of the bracket 3. A fixing block 42 is fixedly connected to the lower end of the connecting column 41. A connecting block 43 is fixedly connected to the middle of the lower end of the fixing block 42. A ball 44 is movably connected to the lower end of the connecting block 43. A connecting rod 45 is fixedly connected to the outer wall of the lower end of the ball 44. A slider 46 is fixedly connected to the lower end of the connecting rod 45. A scanning device 47 is fixedly connected to the lower end of the slider 46. A first transmission mechanism 48 is movably connected to one side of the fixing block 42. The first transmission mechanism 48 includes a first motor 481. A first motor 481 is movably connected to one side of the first motor 481. There is a first slide rod 483, and a slider 46 is slidably connected to the outer wall of the first slide rod 483 on one side. A first connecting groove 484 is opened on the outer wall of one side of the first slide rod 483, and a second connecting groove 485 is opened on the outer wall of the other side of the first slide rod 483. A first connecting piece 482 is movably connected to one side of the first slide rod 483. A first motor 481 is correspondingly connected to the first connecting groove 484 opened on one side of the first slide rod 483. The first connecting piece 482 is correspondingly connected to the second connecting groove 485 opened on one side of the first slide rod 483. A second transmission mechanism 49 is movably connected to one side of the fixed block 42.

[0034] In this embodiment, a support foot 1 is designed, with a placement platform 2 fixedly connected to its upper end. The object to be scanned can be placed on the placement platform 2. A bracket 3 is fixedly connected to the outer wall of the upper end of the placement platform 2, and a movable mechanism 4 is fixedly connected to one side of the upper end of the bracket 3. The lower end of the movable mechanism 4 is correspondingly connected to the upper end of the placement platform 2, thus enabling 3D scanning of the object placed on the upper end of the placement platform 2. The movable mechanism 4 includes a connecting column 41, with a fixing block 42 fixedly connected to the lower end of the connecting column 41. A connecting block 43 is fixedly connected to the middle of the lower end of the fixing block 42. The lower end of the connecting block 43 has a groove and is movably connected to a ball 44. The lower end of the ball 44 is fixedly connected to a connecting rod 45. A first transmission mechanism 48 is connected to one side of the fixing block 42, and the other side of the connecting rod 45 extends to the outer wall of one side of the first transmission mechanism 48 and slides against the outer wall of the first transmission mechanism 48. Block 46 is fixedly connected, and the lower end of slider 46 is fixedly connected to scanning device 47.

The first connecting member 482 is movably connected to the first sliding rod 483 through the second connecting groove 485. Therefore, when the first motor 481 is started, the first motor 481 will drive the first sliding rod 483 to shift its angle around the first connecting member 482 as the axis. At this time, the slider 46 will drive the ball 44 and the connecting rod 45 to shift, which will then drive the scanning device 47 to shift, thereby performing multi-angle scanning.

[0035] Example 2

[0036] like Figure 1-2 and Figure 4 As shown, the second transmission mechanism 49 includes a second motor 491. A second slide rod 493 is movably connected to one side of the second motor 491. The second slide rod 493 is located on one side of the inner wall of the first slide rod 483 and the fixed block 42. A third connecting groove 494 is opened on the outer wall of one side of the second slide rod 493. A fourth connection 495 is opened on the outer wall of the other side of the second slide rod 493. A second connecting piece 492 is movably connected to one side of the second slide rod 493. The second motor 491 is correspondingly connected to the fourth connection 495 opened on one side of the second slide rod 493. The second connecting piece 492 is correspondingly connected to the third connecting groove 494 opened on one side of the second slide rod 493.

[0037] In this embodiment, a second transmission mechanism 49 is provided on one side of the fixed block 42. The second transmission mechanism 49 includes a second motor 491 and a second connecting member 492. The second motor 491 and the second connecting member 492 are connected by a second sliding rod 493. The second motor 491 is fixedly connected to the second sliding rod 493 through a fourth connection 495, while the second connecting member 492 is movably connected to the second sliding rod 493 through a third connecting groove 494. Therefore, when the second motor 491 is started, the second motor 491 will drive the second sliding rod 493 and the second connecting member 492. Rotating around the axis, since the second slide rod 493 is located between the fixed block 42 and the first slide rod 483, and the connecting rod 45 passes through the middle of the second slide rod 493 and extends to one side of the outer wall to be fixedly connected to the slider 46 provided on the first slide rod 483, when the second slide rod 493 moves, it will offset the connecting rod 45, thereby causing the slider 46 and the scanning device 47 to shift in angle. Therefore, through the interaction between the first transmission mechanism 48 and the second transmission mechanism 49, the scanning device 47 can perform three-dimensional scanning of the object placed on the upper end of the placement stage 2.

[0038] Working principle:

[0039] like Figure 1-4As shown, this device, through the coordinated design of support feet 1, placement platform 2, bracket 3, movable mechanism 4, and transmission mechanism, achieves multi-angle 3D scanning of objects on placement platform 2. Support feet 1 provide stable support for the device, placement platform 2 carries the object to be scanned, and bracket 3 is installed on the upper end of placement platform 2, providing support for movable mechanism 4 and scanning device 47. Movable mechanism 4 is located on top of bracket 3, and its structure enables multi-angle movement of scanning device 47. Movable mechanism 4 includes components such as connecting column 41, fixing block 42, connecting block 43, and sphere 44. The bottom of connecting block 43 has a groove, which movably connects to sphere 44. The support rod of scanning device 47—connecting rod 45—is fixedly connected below sphere 44. One end of connecting rod 45 extends to the first transmission mechanism 48 and is fixedly connected to slider 46. The lower end of slider 46 is connected to scanning device 47. The first transmission mechanism 48 consists of first motor 481, first connecting member 482, and first sliding rod 483. The first motor 481 and the first slide rod 483 are fixed together via a connecting groove. The other end of the slide rod is connected to the first connecting member 482 via a movable connecting groove. When the first motor 481 is started, it drives the first slide rod 483 to rotate around the first connecting member 482, causing the connecting rod 45 to shift. At the same time, the slider 46 also moves, thereby realizing the multi-angle swing of the scanning device 47. On one side of the fixed block 42, a second transmission mechanism 49 is also provided to cooperate with the first transmission mechanism 48 to further adjust the scanning angle. The second transmission mechanism 49 includes a second motor 491, a second connecting member 492, and a second slide rod 493. The second motor 491 is fixed to the second slide rod 493 via a connecting groove, and the second slide rod 493 is connected to the second connecting member 492 via a movable connecting groove. After the second motor 491 is started, the second slide bar 493 rotates around the second connecting member 492. Simultaneously, since the second slide bar 493 is connected between the first slide bar 483 and the fixed block 42, and the connecting rod 45 passes through the second slide bar 493, the movement of the second slide bar 493 further drives the connecting rod 45 to shift, ultimately causing the slider 46 and the scanning device 47 to adjust within a wider range of angles. Through the cooperation of the first transmission mechanism 48 and the second transmission mechanism 49, the scanning device 47 can perform omnidirectional, multi-angle three-dimensional scanning of the object on the platform 2, achieving high-precision scanning results. This design effectively improves scanning flexibility and adaptability, providing a solution for scanning complex objects.
