Technical Field

[0001] The present invention belongs to the technical field of scanning devices, and specifically refers to a mechanical fixing arm for cultural relic restoration. Background Art

[0002] Infrared scanning obtains the thermal radiation information of the surface and internal structure of cultural relics by emitting and receiving electromagnetic waves of a specific wavelength. The detection of cultural relics can be completed in a non-contact manner, avoiding the risk of physical damage. However, in order to improve the adaptability to scanned objects, such as scanning objects of various materials or patterns with different depths on the surface, it is necessary to adjust the scanning distance to match the optimal detection distance. Summary of the Invention

[0003] In view of the above situation, the present invention provides a mechanical fixing arm for cultural relic restoration. By the sliding movement of the bilateral extension mechanical arm device in the sliding limit ring component, the distance between the two climbing scanning parts is adjusted. In this way, the distance between the infrared scanning probe and the cultural relic is adjusted to more accurately record and feedback the grooves or concave-convex patterns on the surface of the cultural relic, or adjust the scanning distance according to the material of the scanned cultural relic itself, improve the scanning effect of the infrared scanning probe on the cultural relic, and enhance the accuracy of object scanning.

[0028] Place the object to be scanned on the placement table 12 through the placement opening 17 of the package outer shell 16. Turn on the rotation motor 33, and the rotating ring 34 starts to rotate. The spiral groove 35 engages with the spiral protrusion 26 of the inserted vertical pipe 24.

The side engaging block 56 engages in the inner wall vertical groove 25 of the inserted vertical pipe 24, driving the extension arm member 18 to rotate, thereby driving the bilateral sliding rods 19 to move and rotate synchronously. The top limit ring member 38 and the lower limit ring member 39 are position-fixed components. The upper limit member 40 rotates along with the top sliding plate 31. The suspension ring 49 rotates on the outer wall of the suspension column 44 of the top suspension plate 42.

After realizing the rotational movement of the bilateral extension robotic arm device 1, operate the climbing scanner 3 through the external signal receiving device. After turning on the infrared scanning probe 11, operate the climbing base 10. The climbing base 10 climbs uniformly along the sliding vertical rod 30, and the data scanned by the infrared scanning probe 11 is sent to the external signal receiving device.

[0030] The above is the overall working process of the present invention. Just repeat these steps when using it next time.
