Description

Technical Field

[0001] This utility model relates to the field of film scanning technology, and in particular to a three-axis motion platform for film scanning. Background Technology

[0002] With the rapid development of modern technology, the demand for digitizing historical data is becoming increasingly urgent. This is especially true for film-based data such as historical aerial images, motion pictures, and scientific research films, which carry rich historical, cultural, and scientific information. However, traditional films have a limited lifespan; over time, they age, fade, and deteriorate due to physical wear, light exposure, humidity, and other factors. To extend the lifespan of this valuable data and enable convenient storage, sharing, and research, the digitization of film is of paramount importance.

[0003] Traditional film digitization equipment typically uses low-resolution scanners or digital cameras for shooting. These devices often cannot meet the demands of high-volume, high-precision scanning in terms of accuracy, speed, and automation. Furthermore, traditional scanning equipment generally relies on manual scanning by operators, which is inconvenient for continuous film transport and scanning, resulting in poor work efficiency. Traditional scanning equipment also suffers from difficulties in stitching large-format film, loss of image detail, and color distortion, especially in fields requiring high precision such as aerial imaging and scientific imagery.

[0024] Example 1:

[0025] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a three-axis motion platform for film scanning, including a transport assembly 7. Firstly, through the cooperation of the Y-axis motion platform body 3, the X-axis motion platform body 4, and the Z-axis motion platform body 5, precise fine-tuning and movement of the industrial camera 6 can be achieved on the XYZ axes. The XYZ platform can automatically adjust its position according to the size and format of the film to achieve segmented scanning. There is an appropriate overlap between the images scanned in each scan, which facilitates automatic stitching in the later stage. Furthermore, the transport assembly 7 can continuously and efficiently complete the transfer and scanning of batches of film. For roll film, the transport system can automatically unfold and transport the film and accurately position it to the scanning area, reducing manual operation.

[0026] Y-axis motion platform bodies 3 are provided on both sides of the top of the support base 1. X-axis motion platform bodies 4 are driven to the top two sides of the Y-axis motion platform bodies 3. Z-axis motion platform bodies 5 are driven to the front two sides of the Y-axis motion platform bodies 3. An industrial camera 6 is installed on the front side of the Z-axis motion platform bodies 5. A conveying assembly 7 for conveying film is fixedly connected to one side of the support base 1. An LED backlight panel 8 is provided inside the support base 1. Fixing plates 9 are fixedly connected to the front and rear sides of the bottom of the support base 1. An adjustment assembly 10 for adjusting the height of the LED backlight panel 8 is fixedly connected to one side of the fixing plate 9. A glass plate 11 is fixedly connected inside the support base 1.

[0027] Through the coordination of the Y-axis motion platform 3, X-axis motion platform 4, and Z-axis motion platform 5, precise fine-tuning and movement of the industrial camera 6 can be achieved on the XYZ axes. The XYZ platform can automatically adjust its position according to the size and format of the film, enabling segmented scanning. Each scanned image has an appropriate overlap, facilitating automatic stitching later. Furthermore, the conveyor assembly 7 can continuously and efficiently complete the transfer and scanning of batches of film. For roll film, the conveyor system can automatically unfold and transport the film, accurately positioning it to the scanning area, reducing manual operation. To ensure uniform light distribution during scanning, the system is equipped with an adjustable LED backlight 8. This light source system can automatically adjust the brightness and color temperature according to the transparency and density of the film, ensuring uniform exposure regardless of the film's condition and avoiding overexposure or underexposure. It should be noted that the Y-axis motion platform 3, X-axis motion platform 4, Z-axis motion platform 5, LED backlight 8, and intelligent graphics processing platform 2 are existing technologies and will not be described in detail here.

[0028] The conveying assembly 7 includes a first motor 701 and a transmission roller 702. The first motor 701 is fixed to one side of the support base 1, and the transmission roller 702 is rotatably connected to the inside of the support base 1 through a bearing. The output end of the first motor 701 is fixedly connected to one of the transmission rollers 702. A meshing wheel 703 is fixedly connected to one side of the transmission roller 702, and a toothed belt 704 is meshed with the surface of the meshing wheel 703.

[0029] By turning on the first motor 701, one of the outermost transmission rollers 702 can be driven to rotate the meshing wheel 703. The rotation of the outermost meshing wheel 703 will drive the meshing wheel 703 to rotate, and the rotation of the meshing wheel 703 will drive the toothed belt 704 to rotate. With the transmission of the toothed belt 704, multiple transmission rollers 702 will be driven to transport the film.

[0030] Example 2:

[0031] Reference Figures 3-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] Specifically, an extension plate 12 is fixedly connected to one side of the support base 1, a screw 13 is rotatably connected inside the extension plate 12, and a pressure plate 14 is rotatably connected to the top of the screw 13.

[0033] By rotating the screw 13 inside the extension plate 12, the pressure plate 14 will rise to a limit and press against the toothed belt 704 to prevent the toothed belt 704 from becoming loose.

[0034] Specifically, sliding rods 15 are fixedly connected to both the front and rear sides of the bottom of the pressure plate 14, and the surface of the sliding rods 15 extends through to the bottom of the extension plate 12.

[0035] By fixing the slide bar 15 to the pressure plate 14, the stability of the pressure plate 14 during movement can be improved.

[0036] Specifically, sliders 16 are fixedly connected to both sides of the LED backlight panel 8, and the support base 1 has a groove 17 inside that is used to cooperate with the sliders 16.

[0037] The sliding connection between slider 16 and groove 17 can improve the stability of LED backlight panel 8 when it moves up and down.

[0038] Specifically, a reinforcing block 18 is fixedly connected to one side of the fixing plate 9, and the bottom of the reinforcing block 18 is fixedly connected to the inner wall of the support base 1.

[0039] By fixing the reinforcing block 18 between the support base 1 and the fixing plate 9, the connection strength between the two can be improved.

[0040] Specifically, the adjustment component 10 includes a second motor 1001, which is fixed to one side of the fixed plate 9. The output end of the second motor 1001 extends through to one side of the fixed plate 9 and is fixedly connected to a bidirectional lead screw 1002. One end of the bidirectional lead screw 1002 is rotatably connected to the fixed plate 9 through a bearing. Both the front and rear sides of the surface of the bidirectional lead screw 1002 are threaded with internal thread blocks 1003. The top of the internal thread block 1003 is hinged with a guide plate 1004. The top of the guide plate 1004 is hinged to the LED backlight plate 8. A sliding sleeve 1005 is fixedly connected to one side of the internal thread block 1003. A limit rod 1006 is slidably connected inside the sliding sleeve 1005. The two ends of the limit rod 1006 are fixedly connected to the inner wall of the support base 1, respectively.

[0041] When the user needs to adjust the height of the LED backlight panel 8 and use the glass plate 11 to supplement the film with light, the second motor 1001 can be turned on. As the second motor 1001 is driven, the bidirectional lead screw 1002 will rotate. At this time, the internal thread block 1003 will drive the sliding sleeve 1005 to move in a limited position on the surface of the limiting rod 1006. At the same time, the internal thread block 1003 will drive the guide plate 1004 to adjust the height of the LED backlight panel 8, thereby adjusting the supplementary light intensity.

[0042] In use, the user first places the film on the drive roller 702, then turns on the first motor 701, which drives one of the outermost drive rollers 702 to rotate the meshing wheel 703. The rotation of the outermost meshing wheel 703 drives the meshing wheel 703 to rotate, which in turn drives the toothed belt 704. The rotation of the toothed belt 704, in turn, drives multiple drive rollers 702 to transport the film. Then, through the cooperation of the Y-axis motion platform 3, X-axis motion platform 4, and Z-axis motion platform 5, precise fine-tuning and movement of the industrial camera 6 can be achieved on the XYZ axes. The XYZ platform can automatically adjust its position according to the size and format of the film, achieving segmented scanning. Each scan has an appropriate overlap between images, facilitating automatic stitching later. Furthermore, the conveyor assembly 7 enables continuous high-speed... The system efficiently completes the transfer and scanning of batch films. For roll films, the transport system can automatically unfold and transport the films and accurately position them in the scanning area, reducing manual operation. To ensure uniform light distribution during the scanning process, the system is equipped with an adjustable LED backlight 8. This light source system can automatically adjust the brightness and color temperature according to the transparency and density of the film, ensuring uniform exposure regardless of the film's condition and avoiding overexposure or underexposure. In use, the second motor 1001 can also be turned on. Driven by the second motor 1001, the bidirectional lead screw 1002 will rotate. At this time, the internal thread block 1003 will drive the sliding sleeve 1005 to move in a limited position on the surface of the limiting rod 1006. At the same time, the internal thread block 1003 will drive the guide plate 1004 to adjust the LED backlight 8 up and down, thereby adjusting the supplementary light intensity.
