Description

Technical Field

[0001] This utility model relates to the field of film scanning technology, and specifically to a film digitization scanning device. Background Technology

[0002] Modern industry widely uses X-rays to inspect the welding quality of products in manufacturing industries such as natural gas pipelines, pressure vessels, and bridge engineering. The resulting film requires strict control over the humidity and temperature of the storage environment; improper storage can easily lead to mold and damage, resulting in reduced image quality and difficulty in retrieval. With the development of digitization, the film images are usually scanned and saved to a computer. Digitized data is easier to store, transmit, retain without distortion, and is suitable for long-term preservation.

[0003] Current methods for scanning negatives typically involve placing the negative on a table and then scanning it. However, when negatives are placed on a table, their surfaces are often uneven, which can affect the image quality during scanning. Utility Model Content

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] like Figure 1-3 As shown, a film digitization scanning device includes a stage 1, a scanning component located directly above the stage 1, a pressing component located on the top of the stage 1, a support plate 2 located on the top of the stage 1 that moves towards or away from the pressing component, a smoothing roller 3 located at the bottom of the support plate 2 that can be adjusted for lifting and lowering, a cavity 4 located inside the stage 1, a vacuum tube 5 located at the bottom of the stage 1 that communicates with the cavity 4, and a vacuum pump connected to the other end of the vacuum tube 5, and a plurality of adsorption holes 6 located on the top of the stage 1 that communicate with the cavity 4. The pressing component first presses one side of the film, then the vacuum pump is started to generate adsorption force in the adsorption holes 6, and finally the support plate 2 is moved to drive the smoothing roller 3 to smooth the film, and under the adsorption action of the adsorption holes 6, the film can be tightly attached to the stage, ensuring the flatness of the film and avoiding affecting the imaging effect during scanning.

[0025] The scanning assembly includes a scanner 7 and two support rods 8. Both support rods 8 are fixed to the top of the platform 1 and are arranged sequentially along the moving direction of the support plate 2. A linear motor 9 is fixedly connected between the two support rods 8. The scanner 7 is mounted on the mover of the linear motor 9. The scanner 7 is electrically connected to an external computer. The images captured by the scanner 7 are displayed on the computer. The linear motor 9 can drive the scanner 7 to perform linear movement to adjust the position of the scanner 7 and improve the scanning quality.

[0026] The top of the platform 1 is fixed with two opposing limiting rods 10. Each limiting rod 10 has a slide rail 11 on its side closest to each other. Both sides of the support plate 2 have sliders 12 that slide in cooperation with the slide rails 11, allowing the support plate 2 to slide freely. The bottom of the support plate 2 has a horizontal plate 13, with two opposing first bearings fixedly connected to its bottom. The two ends of the smoothing roller 3 are fixedly connected to the inner rings of the two first bearings. During the movement of the smoothing roller 3 on the surface of the substrate, the freely rotating smoothing roller 3 reduces wear on the substrate. The top of plate 2 is provided with a threaded hole. A second bearing is fixedly connected to the top of the horizontal plate 13. An adjusting screw 14 is fixedly connected to the inner ring of the second bearing. The other end of the adjusting screw 11 passes through the threaded hole and is fixedly connected to a handle 15. The adjusting screw 14 can be rotated by the handle 15, thereby driving the horizontal plate 13 to rise or fall. Two sliding rods 16 are fixedly arranged symmetrically with respect to the adjusting screw 14 on the top of the horizontal plate 13. The support plate 2 is provided with sliding holes that slide with the sliding rods 16, which limit the movement of the horizontal plate 13, allowing the horizontal plate 13 to move only in the vertical direction.

[0027] The clamping assembly includes a top plate 17 and a pressure plate 18. Two connecting rods are fixedly attached to the bottom of the top plate 17 and are fixedly connected to the top of the platform 1. The bottom of the top plate 17 and the top of the pressure plate 18 are fixedly connected by several springs 19. The top of the pressure plate 18 is provided with limiting posts 20 corresponding to each of the springs 19. The springs 19 are sleeved on the outside of the limiting posts 20. The top plate 17 is provided with limiting holes that slide with the limiting posts 20, which can limit the movement of the pressure plate 18, allowing it to move only in the vertical direction. 8. When the bottom sheet is not pressed, the spring 19 is still in a compressed state. The elasticity of the spring 19 can push the pressure plate 18 to press the bottom sheet. The top plate 17 is provided with a pull hole. The top of the pressure plate 18 is fixedly connected to the pull rod 21. The other end of the pull rod 21 passes through the pull hole and is fixedly connected to the pull handle 22. The pull handle 22 can drive the pull rod 21 to rise, thereby driving the pressure plate 18 to rise, which makes it convenient to place the bottom sheet under the pressure plate 18. The bottom of the pressure plate 18 is attached with an anti-slip pad 23 to increase friction and prevent the bottom sheet from loosening.

[0028] Working principle:

[0029] like Figure 1 and 2 As shown, when the scanning device performs digital scanning, the pull handle 22 drives the pull rod 21 to rise, which in turn drives the pressure plate 18 to rise. Then, one side of the film is placed directly under the pressure plate 18. After that, the pull handle 22 is released, and under the elastic action of the spring 19, the pressure plate 18 is pushed to press the film.

[0030] Next, the support plate 2 is pushed to move closer to the pressure plate 18 until the support plate 2 contacts the top plate 17. Then, the adjusting screw 14 is rotated by rotating the handle 15, which in turn drives the horizontal plate 13 to descend, so that the smoothing roller 3 presses the film tightly onto the stage plate 1. Then, the vacuum pump is started to generate suction force through the suction holes 6. Finally, the support plate 2 is pushed to move away from the pressure plate 18, so that the smoothing roller 3 smooths the film. With the suction effect of the suction holes 6, the film can be tightly attached to the stage plate, ensuring the flatness of the film and avoiding affecting the imaging effect during scanning.

[0031] After the film is smoothed, the scanner 7 is started. The image captured by the scanner 7 will be displayed on the computer. The linear motor 9 can drive the scanner 7 to move in a straight line to adjust the position of the scanner 7 and improve the scanning quality.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
