Description

Technical Field

[0001] This utility model relates to the field of 3D modeling of cultural relics, specifically a multi-axis linkage scanning bracket for 3D modeling of cultural relics. Background Technology

[0002] Cultural relics are artifacts and remains left behind by humankind in social activities that possess historical, artistic, and scientific value. They are a precious historical and cultural heritage of humankind. Cultural relics refer to specific material remains, and their basic characteristics are: first, they must be created by humankind or related to human activities; second, they must be things that have become part of the past and cannot be recreated.

[0003] A search revealed prior art publication number CN216046446U, which discloses a scanning device for 3D modeling of cultural relics. This device includes a cylinder with a rotating column rotatably connected to its inner cavity. The top of the rotating column extends through to the top of the cylinder and is fixedly connected to a crosshair. A geared disc is fixedly connected to the surface of the rotating column. A servo motor is installed on the left side of the bottom of the inner cavity of the cylinder. The output shaft of the servo motor is fixedly connected to a gear that meshes with the geared disc. Four through slots are annularly formed at the top of the crosshair. This invention, through the cooperation of a sliding plate and a spring, can clamp cultural relics of different sizes. Through the cooperation of a threaded rod, a handle, and a threaded bracket, the height of the image scanner can be adjusted according to the size of the cultural relic. The cooperation of the servo motor, gear, and geared disc allows the crosshair to rotate stably, thus facilitating 3D scanning of the cultural relic and achieving both convenient adjustment and stable scanning.

[0004] The existing scanning equipment mentioned above cannot rotate the cultural relics along the Z-axis when scanning them, which requires multiple manual adjustments to the position of the cultural relics and consumes more scanning time. Furthermore, the point pressure generated by the clamp when fixing the cultural relics can cause indentations or micro-cracks on the surface of fragile cultural relics (such as lacquerware and pottery). Therefore, based on the above research and in combination with the existing problems, a multi-axis linkage scanning bracket for 3D modeling of cultural relics is provided. Summary of the Invention

[0005] The purpose of this utility model is to provide a multi-axis linkage scanning bracket specifically for 3D modeling of cultural relics, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-axis linkage scanning bracket for 3D modeling of cultural relics, comprising an instrument bracket, a lifting column fixedly installed at the lower end of the instrument bracket, a lifting rack fixedly installed at the side end of the lifting column, a lifting box for controlling the lifting and lowering of the instrument bracket at the side end of the lifting column, a lifting cylinder slidably installed at the lower end of the lifting column, a support column fixedly installed at the lower end of the lifting cylinder, a support frame arrayed at the side end of the support column, a support column fixedly installed at the upper end of the support column away from the lifting cylinder, a rotating box for controlling the rotation of the cultural relic along the X-axis fixedly installed at the upper end of the supporting column, a turntable for placing the cultural relic at the upper end of the rotating box, a slide rail provided at the upper end of the turntable, and a groove provided on the inner wall of the slide rail, a suction cup for fixing the cultural relic at the upper end of the turntable, and a linkage gear for controlling the temperature rotation along the Z-axis at the side end of the suction cup.

[0008] Furthermore, a sliding sleeve is fixedly installed on the side end of the suction cup, and a sliding plate is fixedly installed on the outer wall of the sliding sleeve. The sliding plate is slidably installed on the slide rail provided on the turntable, and a protrusion that fits into the groove of the slide rail is provided at the lower end of the sliding plate. A connecting cylinder is slidably sleeved on the inner wall of the sliding sleeve, and a piston is slidably sleeved on the inner wall of the connecting cylinder. A limiting rack is fixedly installed on the side end of the piston.

[0009] Furthermore, a positioning motor is fixedly installed at the lower end of the turntable, a winder is fixedly installed at the output end of the positioning motor, a rotating cable is wound around the outer wall of the winder, a winding shaft is fixedly installed at the other end of the rotating cable, and the rotating cable is wound around the outer wall of the winding shaft.

[0016] Example: Please refer to Figures 1 to 7 A multi-axis linkage scanning support for 3D modeling of cultural relics includes an instrument support 1. A lifting column 2 is fixedly mounted at the lower end of the instrument support 1. A lifting rack 13 is fixedly mounted at the side end of the lifting column 2. A lifting box 3 for controlling the lifting of the instrument support 1 is located at the side end of the lifting column 2. A lifting cylinder 4 is slidably mounted at the lower end of the lifting column 2. A support column 5 is fixedly mounted at the lower end of the lifting cylinder 4. A support frame 6 is arrayed at the side end of the support column 5. A support column 7 is fixedly mounted at the upper end of the support column 5 away from the lifting cylinder 4. A rotating box 14 for controlling the rotation of the cultural relic along the X-axis is fixedly mounted at the upper end of the supporting column 7. A turntable 8 for placing the cultural relic is located at the upper end of the rotating box 14. The upper end of the instrument is provided with a slide rail, and the inner wall of the slide rail is provided with a groove. The upper end of the turntable 8 is provided with a suction cup 18 for fixing the artifact. The side end of the suction cup 18 is provided with a linkage gear 37 for controlling the temperature and rotating along the Z-axis. When scanning the artifact, the artifact is placed on the upper end of the turntable 8 and fixed by the suction cup 18. The scanner is placed on the upper end of the instrument support 1. The height of the scanner is adjusted by the lifting box 3 so that the scanner focus is aligned with feature points at different depths. The turntable 8 is rotated by the rotating box 14 so that the artifact rotates along the X-axis. The linkage gear 37 drives the slide plate 19 to rotate so that the artifact rotates along the Z-axis, so that the scanner can accurately capture the micro-morphology of the artifact, such as undulations.

[0017] Example: Please refer to Figures 1-3A lifting motor 9 is fixedly installed at the lower end of the lifting box 3. A drive gear 10 is fixedly installed at the output end of the lifting motor 9. A driven gear 11 is rotatably installed at the upper end of the drive gear 10, and the driven gear 11 is meshed with the lifting rack 13 and the drive gear 10. A connecting rod 12 is fixedly installed on the inner wall of the driven gear 11. A rotating motor 15 is fixedly installed at the lower end of the rotating box 14. A worm gear 16 is fixedly installed at the output end of the rotating motor 15. A worm wheel 17 is rotatably installed at the side end of the worm gear 16, and the worm wheel 17 is meshed with the worm gear 16. When the lifting motor 9 is started, the lifting motor... Motor 9 drives the drive gear 10 to rotate, which in turn drives the driven gear 11 to rotate around the connecting rod 12. The driven gear 11 drives the lifting rack 13 to move upward, causing the lifting column 2 to move the instrument support 1 upward, thus raising the scanner's viewing angle. When the lifting motor 9 rotates in the reverse direction, it drives the drive gear 10 to rotate in the reverse direction, which in turn drives the driven gear 11 to rotate in the reverse direction around the connecting rod 12. The driven gear 11 drives the lifting rack 13 to move downward, causing the lifting column 2 to move the instrument support 1 downward, thus lowering the scanner's viewing angle. When the rotating motor 15 starts, it drives the worm gear 16 to rotate, which in turn drives the worm wheel 17 to rotate, causing the turntable 8 to rotate the artifact. When the rotating motor 15 rotates in the reverse direction, it drives the worm gear 16 to rotate in the reverse direction, which in turn drives the worm wheel 17 to rotate in the reverse direction, causing the turntable 8 to rotate the artifact in the reverse direction, enabling the scanner to accurately capture the artifact's microscopic features such as undulations.

[0018] Example: Please refer to Figures 1-5 A sliding sleeve 20 is fixedly installed on the side end of the suction cup 18. A sliding plate 19 is fixedly installed on the outer wall of the sliding sleeve 20. The sliding plate 19 is slidably installed on the slide rail provided on the turntable 8.

A piston 22 is slidably sleeved on the inner wall of the connecting cylinder 21. A limiting rack 32 is fixedly installed on the side end of the piston 22. When the suction cup 18 is close to the cultural relic, the piston 22 moves to the end away from the suction cup 18, drawing the air from the inner wall of the suction cup 18 into the sliding sleeve 20, thus fixing the cultural relic.

[0019] Example: Please refer to Figures 2-7A positioning motor 30 is fixedly installed at the lower end of the turntable 8. A winder 31 is fixedly installed at the output end of the positioning motor 30. A rotating cable 29 is wound around the outer wall of the winder 31. A winding shaft 26 is fixedly installed at the other end of the rotating cable 29, and the rotating cable 29 is wound around the outer wall of the winding shaft 26. A rotating rod 28 is fixedly installed at the upper end of the winding shaft 26. A fixing plate 27 is fixedly installed on the outer wall of the rotating rod 28, and the rotating rod 28 is rotatably mounted on the inner wall of the fixing plate 27. When the positioning motor 30 is started, the positioning motor 30 drives the winder 31 to rotate. The winder 31 shortens the rotating cable 29 and winds it around its outer wall. The rotating cable 29 drives the winding shaft 26 to rotate. When the positioning motor 30 rotates in the opposite direction, the positioning motor 30 drives the winder 31 to rotate in the opposite direction. The winder 31 extends the rotating cable 29, and the rotating cable 29 drives the winding shaft 26 to rotate in the opposite direction.

[0020] Example: Please refer to Figures 3-7 A terminal block 25 is fixedly installed at the upper end of the rotating rod 28. A fixing cable 24 is wound around the outer wall of the terminal block 25. The other end of the fixing cable 24 is fixedly connected to a collar 23, which is fixedly installed on the side of the rotating cable 29. The winding shaft 26 drives the rotating rod 28 and the terminal block 25 to rotate. The terminal block 25 causes the fixing cable 24 to shorten and be wound around its outer wall. The fixing cable 24 drives the slide plate 19 to move along the slide rail at the upper end of the turntable 8 towards the end closer to the terminal block 25 through the collar 23. The winding shaft 26 rotates in the opposite direction, causing the rotating rod 28 and the terminal block 25 to rotate in the opposite direction. The terminal block 25 causes the fixing cable 24 to extend. The fixing cable 24 drives the slide plate 19 along the slide rail at the upper end of the turntable 8 towards the end closer to the artifact through the collar 23, thus fixing the artifact.

[0021] Example: Please refer to Figures 4-7A fixing rod 35 is fixedly installed on the upper end of the fixing plate 27. A transmission rod 36 is rotatably mounted on the inner wall of the fixing rod 35. A transmission gear 34 is fixedly installed on the end of the transmission rod 36 near the limiting rack 32, and the transmission gear 34 is meshed with the limiting rack 32. A rotating gear 33 is fixedly installed on the upper end of the terminal 25, and the rotating gear 33 is meshed with the transmission gear 34. A crown gear 38 is fixedly installed on the upper end of the turntable 8. When the terminal 25 rotates, the terminal 25 drives the transmission gear 34 to rotate around the transmission rod 36 as the center point. 4. The piston 22 is moved away from the connecting cylinder 21, causing the air inside the suction cup 18 to be drawn into the sliding sleeve 20, thus fixing the artifact. When the terminal 25 rotates in the opposite direction, the terminal 25 drives the transmission gear 34 to rotate in the opposite direction with the transmission rod 36 as the center point. The transmission gear 34 drives the piston 22 to move closer to the artifact, causing the air inside the sliding sleeve 20 to be discharged into the suction cup 18, thus releasing the artifact. When the turntable 8 rotates, the crown gear 38 rotates and drives the linkage gear 37 to rotate, causing the artifact to rotate along the Z-axis, so that the scanner can accurately capture the microscopic shape of the artifact, such as undulations.

[0022] Working principle: When scanning cultural relics, the relics are placed on the top of the turntable 8 and fixed by the suction cup 18. The scanner is placed on the top of the instrument support 1. The lifting motor 9 is started, which drives the drive gear 10 to rotate. The drive gear 10 drives the driven gear 11 to rotate around the connecting rod 12. The driven gear 11 drives the lifting rack 13 to move upward, causing the lifting column 2 to move the instrument support 1 upward, thus raising the scanner's viewing angle. When the lifting motor 9 rotates in the opposite direction, it drives the drive gear 10 to rotate in the opposite direction, which drives the driven gear 11 to rotate in the opposite direction around the connecting rod 12. The driven gear 11 drives the lifting rack 13 to move downward, causing the lifting column 2 to move the instrument support 1 downward, thus lowering the scanner's viewing angle. When the rotating motor 15 starts, it drives the worm gear 16 to rotate, which in turn drives the worm wheel 17 to rotate, causing the turntable 8 to rotate the artifact. When the rotating motor 15 rotates in the opposite direction, it drives the worm gear 16 to rotate in the opposite direction, which in turn drives the worm wheel 17 to rotate in the opposite direction, causing the turntable 8 to rotate the artifact in the opposite direction, enabling the scanner to accurately capture the microscopic features of the artifact, such as its undulations.

[0023] When the positioning motor 30 starts, it drives the winder 31 to rotate. The winder 31 shortens the rotating cable 29 and winds it around its outer wall. The rotating cable 29 drives the winding shaft 26 to rotate. The winding shaft 26 drives the rotating rod 28 and the terminal block 25 to rotate. The terminal block 25 shortens the fixing cable 24 and winds it around its outer wall. The fixing cable 24 drives the slide plate 19 to move along the upper rail of the turntable 8 towards the end closer to the terminal block 25 through the collar 23. When the positioning motor 30 rotates in the opposite direction, it drives the winder 31 to rotate in the opposite direction. The winder 31 extends the rotating cable 29. The rotating cable 29 drives the winding shaft 26 to rotate in the opposite direction. The winding shaft 26 drives the rotating rod 28 and the terminal block 25 to rotate in the opposite direction. The terminal block 25 extends the fixing cable 24. The fixing cable 24 drives the slide plate 19 along the upper rail of the turntable 8 towards the end closer to the artifact through the collar 23, thus fixing the artifact.

[0024] When the terminal 25 rotates, it drives the transmission gear 34 to rotate around the transmission rod 36. The transmission gear 34 drives the piston 22 to move away from the connecting cylinder 21, drawing air from the inner wall of the suction cup 18 into the sliding sleeve 20 and fixing the artifact. When the terminal 25 rotates in the opposite direction, it drives the transmission gear 34 to rotate in the opposite direction around the transmission rod 36. The transmission gear 34 drives the piston 22 to move closer to the artifact, expelling air from the inner wall of the sliding sleeve 20 into the suction cup 18 and releasing the artifact. When the turntable 8 rotates, the crown gear 38 rotates and drives the linkage gear 37 to rotate, causing the artifact to rotate along the Z-axis, enabling the scanner to accurately capture the microscopic features of the artifact, such as undulations.
