Description

Technical Field

[0001] This utility model relates to the field of archival data detection technology, specifically to a digital archival data detection and scanning device. Background Technology

[0002] With the rapid development of the information society, the contradiction between traditional archival work methods and the objective needs of the times is becoming increasingly acute. Due to the inefficiency of traditional archival management methods, archival data resources are currently undergoing a transformation towards digitalization. The form of archival resources is undergoing a qualitative change from analog and digital to data. Archival data will become the main body of archival information resources in the data era. Archival work is undergoing a process of adaptation from managing physical archives to managing archival data.

[0003] A data quality testing device for archives, with announcement number CN220935225U, includes a base, a data storage device, and an archive scanner. A mounting frame is fixedly connected to the base, and a moving component for raising and lowering the archive scanner is mounted on the mounting frame. A limiting component for positioning the archive is also provided on the base. This invention features a reasonable design structure. The limiting component ensures the archive remains fixed in a position on the base, while the moving component allows for height adjustment of the archive scanner. This significant adjustment provides a longer depth of field, and the lighting component provides supplemental lighting to the scanned archive. This allows the scanner to switch focus positions when scanning text of different sizes on the archive, thereby ensuring the accuracy of the data quality analysis.

[0004] This device scans documents by placing them directly on a base. Stray light from the external environment can interfere with the stability of the scanner's light source, causing reflections, glare, or color casts in the image. Uneven ambient lighting can also lead to loss of detail in shadow areas or overexposure in bright areas, reducing the recognition rate and thus affecting scan clarity. Therefore, those skilled in the art provide a digital document data inspection and scanning device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a digital archival data detection and scanning device to solve the problems in the prior art where the archival paper is placed directly on the base for scanning. In such cases, stray light from the external environment can interfere with the stability of the scanner's light source, causing reflections, glare, or color shifts in the image. Uneven ambient lighting may also cause loss of detail in shadow areas or overexposure in bright areas, reducing the recognition rate and thus affecting the clarity of the scan.

[0023] 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.

[0024] Please see Figures 1-5As shown, this utility model provides a technical solution: a digital archive data detection and scanning device, including a base 1, a covering component 2 for covering the detection environment on the upper surface of the base 1, a scanning component 5 for detection and scanning installed inside the covering component 2, a fixing component 3 for fixing the archive paper installed on the upper surface of the base 1, and a cleaning component 4 for cleaning the archive paper installed inside the base 1.

[0025] This digital archival data detection and scanning device uses a fixing component 3 to press and fix the archival paper to be scanned onto a base 1. The cylinder 202 in the covering component 2 drives the covering box 203 to descend until it contacts the upper end of the base 1. The covering box 203, in conjunction with the base 1, shields the archival paper, preventing direct sunlight from causing reflections on the text on the paper, ensuring scanning clarity and color reproduction. Furthermore, the light-shielding condition reduces the workload of the photosensitive element of the scanning component 5, improving scanning efficiency and extending hardware life. During the descent of the covering box 203, the cleaning component 4 moves the cleaning broom 406 to wipe the surface of the paper archival paper. Using the cleaning broom 406 to wipe the dust off the surface of the archival paper effectively improves scanning quality and prevents dust particles from causing image blurring or spots.

[0026] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the covering assembly 2 includes a fixing frame 201, which is fixedly connected to the upper surface of the base 1. A cylinder 202 is fixedly installed on the end face of the fixing frame 201 away from the base 1. The output end of the cylinder 202 passes through the fixing frame 201, and the output end of the cylinder 202 is fixedly connected to the covering box 203.

[0027] The cylinder 202 in the masking assembly 2 drives the masking box 203 to descend until the masking box 203 contacts the upper end of the base 1. When the pressure sensor 7 detects that the masking box 203 has applied a certain pressure to the base 1, the cylinder 202 stops working. The masking box 203, in conjunction with the base 1, shields the paper documents, preventing direct sunlight from causing reflections on the paper documents, ensuring scanning clarity and color reproduction. Furthermore, the light-shielding condition can reduce the workload of the photosensitive element of the scanning assembly 5, improve scanning efficiency, and extend the hardware life.

[0028] As one implementation method in this embodiment, please refer to Figure 1 and Figure 4As shown, the fixing component 3 includes a vertical plate 301, which is fixedly connected to the upper end face of the base 1. A lifting port 302 is opened in the vertical plate 301. A first threaded rod 303 is rotatably connected to the inner wall of the lifting port 302. A lifting block 304 is threadedly sleeved on the first threaded rod 303. A pressing plate 305 is fixedly connected to one end face of the lifting block 304 near the base 1. A knob 306 is rotatably sleeved on the upper end face of the vertical plate 301. The output end of the knob 306 is fixedly connected to the upper end of the first threaded rod 303.

[0029] Place the document to be scanned on the base 1, then turn the knob 306. The first threaded rod 303 rotates. Since the pressing plate 305 is attached to the side wall of the upright plate 301 for limiting, turning the first threaded rod 303 will not rotate the lifting block 304. The lifting block 304 will slide in the lifting port 302, thereby causing the pressing plate 305 to descend. The pressing plate 305 cooperates with the upper surface of the base 1 to press and fix the paper on the base 1.

[0030] As one implementation method in this embodiment, please refer to Figure 3 As shown, the cleaning component 4 includes a sliding groove 401, which is formed inside the base 1. A second threaded rod 402 is rotatably connected to the inner wall of the sliding groove 401. A movable frame 403 is slidably connected inside the sliding groove 401. The second threaded rod 402 is threadedly sleeved at the center of the movable frame 403. A spur gear 404 is rotatably connected to the side wall of the base 1. The output shaft of the spur gear 404 passes through the base 1 and is fixedly connected to one end of the second threaded rod 402. A rack 405 is fixedly connected to the side wall of the cover box 203. The rack 405 and the spur gear 404 mesh with each other. A cleaning broom 406 is fixedly connected to the inner wall of the upper end of the movable frame 403. The bristles of the cleaning broom 406 are attached to the upper surface of the base 1.

[0031] During the descent of the cover box 203, the rack 405 on the cover box 203 will contact the spur gear 404, and then the second threaded rod 402 will rotate, causing the moving frame 403 to move towards one side of the spur gear 404. The cleaning broom 406 will wipe the surface of the paper document. Using the cleaning broom 406 to wipe and remove dust from the surface of the document can effectively improve the scanning quality and avoid image blurring or spots caused by dust particles. When the cover box 203 descends to the same height as the upper surface of the moving frame 403, the moving frame 403 has moved out from under the cover box 203 and the moving frame 403 will not affect the descent of the cover box 203.

[0032] As one implementation method in this embodiment, please refer to Figure 5 As shown, the scanning component 5 includes two illumination lamps 501, which are fixedly connected to both sides of the upper inner wall of the cover box 203. A scanning camera 502 is fixedly installed on the upper inner wall of the cover box 203, and the scanning camera 502 is located between the two illumination lamps 501.

[0033] After the cover box 203 contacts the upper end of the base 1, the illumination lamp 501 and the scanning camera 502 start to work. Both the illumination lamp 501 and the scanning camera 502 are existing technologies. The principle is that the illumination lamp 501 emits uniform light to illuminate the surface of the target object. The light signal reflected or transmitted by the object is focused by the optical lens of the scanning camera 502 onto the photoelectric sensor. The sensor converts the light signal into an analog electrical signal, which is then processed into a digital signal by an analog-to-digital converter. Finally, the computer system stores it as an editable digital image or data file to realize the scanning of data on the paper. The scanning camera 502 then transmits the scanned data to the data storage device, thus completing the scanning and storage of the archive. This will not be elaborated further here.

[0034] As one implementation method in this embodiment, please refer to Figure 1 As shown, two support frames 6 are fixedly connected to the lower end of the base 1. The two support frames 6 are arranged symmetrically, and the ends of the two support frames 6 away from the base 1 are provided with anti-slip textures.

[0035] The support frame 6 can support the base 1, improving the stability of the device, and also raise the base 1 to a certain height, ensuring that the rack 405 will not contact the placement surface after it descends to the lowest point.

[0036] As one implementation method in this embodiment, please refer to Figure 3 As shown, a pressure sensor 7 is fixedly installed on the lower end face of the cover box 203.

[0037] The pressure sensor 7 is existing technology. Its working principle is to convert the external pressure signal into a measurable electrical signal through a sensitive element. When pressure is applied to the pressure sensor 7, the sensitive element deforms or generates charge, resulting in changes in electrical characteristics such as resistance, capacitance or voltage. The signal conditioning circuit amplifies and linearizes these changes, and finally outputs a standard electrical signal proportional to the pressure, so as to realize the accurate detection and transmission of pressure. That is, when the pressure sensor 7 detects that the cover box 203 applies a certain pressure to the base 1, the cylinder 202 stops working. This will not be described in detail here.

[0038] Working principle: First, place the document to be scanned on the base 1. Then, turn the knob 306, and the first threaded rod 303 rotates. Since the pressing plate 305 is attached to the side wall of the upright plate 301 for limiting, turning the first threaded rod 303 will not rotate the lifting block 304. The lifting block 304 will slide within the lifting port 302, thereby causing the pressing plate 305 to descend. The pressing plate 305, in conjunction with the upper surface of the base 1, can press and fix the paper on the base 1. Then, the cylinder 202 in the cover assembly 2 drives the cover box 203 to descend until the cover box 203 contacts the upper end of the base 1. When the pressure sensor 7 detects that the cover box 203 has applied a certain pressure to the base 1, the cylinder 202 stops working. The cover box 203, in conjunction with the base 1, achieves the shielding of the document, avoiding direct sunlight from causing reflections on the text on the paper document, ensuring scanning clarity and color reproduction. Furthermore, the light shielding condition can reduce the scanning assembly 5 The workload of the photosensitive element is reduced, improving scanning efficiency and extending hardware lifespan. During the descent of the cover box 203, the rack 405 on the cover box 203 contacts the spur gear 404, and then the second threaded rod 402 rotates, causing the moving frame 403 to move towards one side of the spur gear 404. The cleaning broom 406 wipes the surface of the paper document. Using the cleaning broom 406 to wipe and remove dust from the surface of the document can effectively improve scanning quality and avoid image blurring or spots caused by dust particles. When the cover box 203 descends to the same height as the upper surface of the moving frame 403, the moving frame 403 has moved out from under the cover box 203. The moving frame 403 will not affect the descent of the cover box 203. After the cover box 203 contacts the upper end of the base 1, the illumination lamp 501 and the scanning camera 502 start working to scan the data on the paper. The scanning camera 502 then transmits the scanned data to the data storage device.

[0039] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
