Description

Technical Field

[0001] This utility model relates to the technical field of cultural relic scanning devices, specifically to an automatic scanning device for cultural relic modeling. Background Technology

[0002] Automatic scanning devices for cultural relic modeling refer to intelligent equipment that uses automation technology to acquire three-dimensional data of cultural relics. Their core function is to rapidly acquire high-precision geometric and textural information non-contactly and automatically generate digital models. These devices avoid the risks of physical contact inherent in traditional measurement methods, creating long-term digital archives for cultural relics and mitigating information loss due to natural disasters, human damage, or natural aging.

[0003] Existing automatic scanning devices do not have the function of protective scanning of cultural relics. The process of acquiring three-dimensional data usually takes about an hour or longer. The cultural relics are placed naked on the scanning table. When cultural relics are exposed to the air, they will be corroded by oxygen. Especially in high humidity environments, the oxidation process will be accelerated, resulting in greater corrosion of the cultural relics and affecting their safety. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] like Figures 1-5 As shown, this utility model provides a technical solution: an automatic scanning device for modeling cultural relics, comprising:

[0031] Workbench 1;

[0032] The protective scanning mechanism 2 is located on top of the workbench 1 and is used to protect the cultural relics during scanning.

[0033] Automatic scanning mechanism 3 is located on top of workbench 1 and is used to automatically scan cultural relics.

[0034] As one implementation method in this embodiment, such as Figures 1-3 As shown, the protective scanning mechanism 2 includes a circular base 21, which is fixedly installed at the center of the top of the worktable 1. A limiting strip 22 is fixedly installed on the top of the circular base 21. A movable seat 23 is movably inserted into the inner wall of the limiting strip 22. The bottom of the movable seat 23 is movably connected to the top of the circular base 21. If the cultural relic needs protection, the movable seat 23 is inserted into the limiting strip 22. If the cultural relic does not need protection, the cultural relic is placed directly on the top of the circular base 21 with the help of a fitting bracket, and then scanning can be performed.

[0035] As one implementation method in this embodiment, such as Figures 1-3 As shown, a glass cover 24 is fixedly installed on the top of the movable base 23. A one-way valve 25 is fixedly connected to the outer wall of the glass cover 24 near the bottom. A hollow top plate 26 is movably connected to the top of the glass cover 24. A valve 27 is fixedly connected to the top of the hollow top plate 26. A handle 28 is fixedly installed on the top of the hollow top plate 26. A through hole 261 is opened at the bottom of the hollow top plate 26. A protruding frame 262 is fixedly installed at the bottom of the hollow top plate 26. A rubber ring 263 is fixedly fitted on the outer wall of the protruding frame 262. The outer wall of the rubber ring 263 is movably connected to the inner wall of the glass cover 24. A surface light source 29 is fixedly installed at the bottom of the hollow top plate 26. When protecting cultural relics, the first step is to use the glass cover 24 to protect the cultural relics. The hollow top plate 26 is removed from the top of the glass cover 24 to add the artifact into the inner cavity of the glass cover 24. Then, the control valve 27 is opened, and nitrogen gas is supplied into the inner cavity of the hollow top plate 26 through the valve 27 using a vacuum nitrogen sterilizer. The nitrogen gas in the inner cavity of the hollow top plate 26 then enters the glass cover 24 through the through hole 261, replacing the original air inside the glass cover 24 through the one-way valve 25. This creates a low-oxygen, low-humidity environment in the inner cavity of the glass cover 24, ensuring the safety of the artifact during the scanning process. Then, the valve 27 is closed and the vacuum nitrogen sterilizer is removed. During the scanning process, the surface light source 29 is controlled to work, which can provide supplemental lighting for the artifact and improve the scanning effect.

[0036] As one implementation method in this embodiment, such as Figure 4As shown, the automatic scanning mechanism 3 includes a ring track 31, which is fixedly installed on the top of the worktable 1. An active sliding seat 32 is slidably connected to the top of the ring track 31. A stepper motor 33 is fixedly installed on the top of the active sliding seat 32. A moving wheel 34 is fixedly connected to the output shaft of the stepper motor 33. The outer wall of the moving wheel 34 is movably connected to the outer wall of the ring track 31. A first stand 35 is fixedly installed on the top of the active sliding seat 32. A lead screw 36 is rotatably connected between the top and bottom of the inner wall of the first stand 35. A servo motor 39 is fixedly installed on the top of the first stand 35. The output shaft of the servo motor 39 is fixedly connected to the top of the lead screw 36. A lifting seat 37 is slidably connected to the first stand 35 and the lead screw 36. A scanner body 38 is detachably connected to the lifting seat 37. The scanner body 38 is existing technology and can be an Artec... The Leo 3D scanner can scan artifacts through a glass enclosure 24. The scanned data can be transmitted to a computer and displayed on a screen. In use, the computer controls the stepper motor 33 and the servo motor 39. Controlling the stepper motor 33 drives the moving wheel 34 to rotate. The moving wheel 34 rolls on the outer wall of the annular track 31, which in turn drives the active sliding seat 32 to slide on the outer wall of the annular track 31, allowing the scanner body 38 to rotate around the artifact. To switch the scanning position, the servo motor 39 drives the lead screw 36 to rotate, which in turn causes the lifting seat 37 to slide on the outer wall of the first stand 35, adjusting the height of the scanner body 38. This enables automated scanning and reduces the labor intensity of the staff.

[0037] As one implementation method in this embodiment, such as Figure 5 As shown, a crossbar 351 is fixedly connected to the side of the first stand 35. A second stand 352 is fixedly installed at the end of the crossbar 351 away from the first stand 35. A driven slide seat 353 is fixedly installed at the bottom of the second stand 352. The driven slide seat 353 is slidably connected to the top of the annular track 31. While the active slide seat 32 slides on the annular track 31, the driven slide seat 353 can slide on the annular track 31 through the transmission of the crossbar 351 and the second stand 352. Through the design of the crossbar 351, the second stand 352 and the driven slide seat 353, the overall stability of the first stand 35 can be improved, ensuring the scanning effect of the scanner body 38.

[0038] Working Principle: When using this device, to protect the artifact, firstly, the hollow top plate 26 is removed from the top of the glass cover 24 to add the artifact into the inner cavity of the glass cover 24. Then, valve 27 is opened, and a vacuum nitrogen sterilizer delivers nitrogen gas through valve 27 and the hollow top plate 26 into the inner cavity of the glass cover 24, replacing the existing air inside the glass cover 24 through one-way valve 25. This creates a low-oxygen, low-humidity environment within the inner cavity of the glass cover 24, ensuring the safety of the artifact during scanning. Then, valve 27 is closed and the vacuum nitrogen sterilizer is removed. Next, the scanner body 38 is controlled to scan the artifact through the glass cover 24. The scanned data can be transmitted to a computer. During scanning, stepper motor 33 is controlled to rotate the scanner body 38 around the artifact, changing the scanning position. Servo motor 39 is controlled to adjust the height of the scanner body 38, thus achieving automated scanning.
