A 3D printer can be used to print products that are consistent with the size and shape of real objects in reality. Before 3D printing, the object needs to be scanned at multiple angles using a 3D scanner. The scanning method is usually to rotate the object to be scanned, fix the scanner, scan the rotating object, and then adjust the height and angle of the scanner one by one to make the scanner scan more comprehensively. In the existing technology, the height and angle of the scanner need to be adjusted manually many times, and the uniform movement of the scanner cannot be guaranteed, which easily causes a large area of ​​repeated scanning, consumes electricity, or there are gaps in the scanning, resulting in incomplete scanning.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1 A multi-angle machine vision inspection device comprises a base frame 1, a motor 2 is fixedly connected to the upper part of the base frame 1, a turntable 3 is fixedly sleeved on the driving end of the motor 2, a notch 4 is opened on the outer edge of the turntable 3, the notch 4 is arranged in an arc shape, a pad 5 located on the upper side of the notch 4 is fixedly connected to the turntable 3, the top of the pad 5 has a spirally ascending inclined surface and a horizontal surface smoothly connected to the inclined surface, the inclined surface of the pad 5 is smoothly connected to the upper side wall of the turntable 3, and the upper side wall of the base frame 1 is provided with a transmission component located on one side of the turntable 3 and a horizontal surface on the transmission component The visual recognition device comprises a transmission assembly including a guide column 8 fixedly connected to the base frame 1, the guide column 8 is vertically arranged, a guide sleeve 9 is provided on the sliding sleeve of the guide column 8, a spring is fixedly connected between the guide sleeve 9 and the upper side wall of the base frame 1, a through slot is provided on the base frame 1, a movable plate 6 penetrating the through slot is fixedly connected to one side of the guide sleeve 9, a plurality of evenly distributed planar teeth 7 are fixedly provided on the movable plate 6, the pad 5 is in sliding contact with the lower side wall of the planar teeth 7 by rotation, and the spacing between adjacent planar teeth 7 is slightly larger than the distance from the lower side wall of the turntable 3 to the horizontal upper side wall of the pad 5.

[0019] Place the object to be scanned in the middle of the turntable 3, start the motor 2, and the motor 2 drives the turntable 3 to rotate slowly counterclockwise. At this time, the upper side wall of the turntable 3 slides relative to the plane tooth 7. When the pad 5 contacts the plane tooth 7, as the pad 5 rotates, the plane tooth 7 will rise along the inclined surface of the pad 5. When the lower side wall of the plane tooth 7 contacts the horizontal surface on the pad 5, the next plane tooth 7 has passed through the gap 4 and is located on the upper side of the turntable 3. When the pad 5 rotates out of the plane tooth 7, the plane tooth 7 will clamp the turntable 3 under the tension of the spring. And so on, every time the turntable 3 rotates one circle, the moving plate 6 rises to the height of a plane tooth 7.

[0020] Reference Figure 2The transmission assembly also includes a gear mechanism arranged on the upper side of the movable plate 6, the gear mechanism includes a support frame 10 fixedly connected to the upper side wall of the movable plate 6, and a gear 14 is rotatably arranged on the support frame 10. The visual recognition device includes a connecting frame and a scanner 11, the scanner 11 is fixedly connected to the connecting frame, and the connecting frame is fixedly connected to the outer side wall of the gear 14. A gear 2 15 meshing with the gear 14 is rotatably arranged on the support frame 10, and the gear 2 15 is located on the left side of the gear 14. A toothed plate 12 is arranged on the left side of the gear 2 15, and the gear 2 15 meshes with the toothed plate 12, and the diameter of the gear 2 15 is smaller than the diameter of the gear 14.

[0021] As the movable plate 6 rises, the support frame 10 drives the gear 2 15 to rise, and the gear 2 15 meshes with the toothed plate 12. The gear 2 15 will rotate counterclockwise, and at the same time, the gear 2 15 drives the gear 1 14 to rotate clockwise, and the scanner 11 fixed on the gear 1 14 will also flip downward. Since the diameter of the gear 2 15 is smaller than the diameter of the gear 1 14, the rotation angle of the gear 14 is smaller than the rotation angle of the gear 2 15, that is, the angle of rotation of the scanner 11 each time is small, and incomplete scanning will not occur.

[0022] Reference Figure 3 A sliding mechanism is provided on the upper side wall of the base frame 1, and the sliding mechanism includes a slide groove 13 fixedly connected to the upper side wall of the base frame 1, a slider 16 is slidably provided in the slide groove 13, and the slider 16 is fixedly connected to the lower end of the tooth plate 12. The slider 16 is arranged in a "convex" shape, and a threaded through hole is opened on the upper side wall of the slide groove 13. A bolt 17 is screwed in the threaded through hole. The lower end of the bolt 17 corresponds to the outer side wall of the slider 16, and the upper end of the bolt 17 is fixedly connected with a turning handle. Rotating the turning handle can make the inner end of the bolt 17 squeeze and rub against the slider 16, so that the slider 16 is fixed in the slide groove 13.

[0023] When initially scanning an object, it is necessary to adjust the position of the scanner 11. At this time, loosen the bolt 17, move the slider 16 to separate the gear 2 15 from the tooth plate 12, turn the gear 14, adjust the angle of the scanner 11, and then move the tooth plate 12 to engage the gear 2 15 with the tooth plate 12, tighten the bolt 17 to fix the tooth plate 12. When the scanning is completed, it is also necessary to adjust the sliding mechanism to separate the tooth plate 12 from the gear 2 15, and lower the scanner 11 to the bottom for scanning on the lower side.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
