technical field

The invention relates to the technical field of office equipment, in particular to an integrated intelligent document processing device and a processing method.

Background technique

Government agencies, public institutions, large and medium-sized enterprises and other institutions produce a large number of paper documents that need to be archived in their daily work. In response to archiving requirements, relevant state agencies have issued a series of policies and standards. According to relevant requirements, paper documents need to be printed and coded (referred to as coding, the same below) before they are archived, that is, the side of the paper document that contains characters needs to be coded; otherwise, no coding is required. After the coding is completed, the coded documents are scanned page by page in order to generate corresponding electronic files, which can not only realize the one-to-one correspondence between paper documents and electronic files, but also improve the efficiency of file search. However, at present, these tasks are highly dependent on manual labor, and there are problems such as low operation efficiency, uneven operation quality, and high cost.

In order to solve the above technical problems, the patent document with the publication number CN111267498A discloses an intelligent pagination coding machine and a coding method. Detection mechanism, induction inkjet mechanism and pressure roller. The method is to put the paper to be sorted and coded between the two baffles of the workbench of the machine body, through the paper feed wheel and the reverse push wheel to sort the pages one by one, the paper detection mechanism automatically recognizes the content of the paper, the feedback system judges, and through the induction coding The organization performs coding, and finally collects them uniformly to complete the coding work. The coding machine forms an integrated process of page-by-page coding of paper document materials, which simultaneously improves the efficiency and accuracy of page-by-page coding of paper. But in actual application, the coding machine still has the following technical problems:

1. The coding machine only recognizes whether there are words on the back of the paper. The specific performance is: if the back of the paper is blank after comparison, only the front of the paper is sprayed; if there are words on the back of the paper after comparison, both the front and back of the paper need to be sprayed. code. However, in the actual file management process, there are often situations where the paper is reversed. Therefore, when the paper is reversed, it will cause the blank back of the paper to be sprayed, which will cause errors in the conversion of paper documents.

2. The coding machine only prints codes on paper documents, but does not encode converted electronic documents. The paper documents and electronic documents cannot correspond one-to-one, which is not conducive to later management.

3. The coding machine only realizes the paper transportation through the cooperation of the belt pulley and the paper feed wheel. The structure is relatively simple. On the one hand, the paper is easy to deviate during transportation; The actual use effect is poor.

4. The coding machine realizes the feeding of the paper documents to be processed through the cooperation of the paper feed wheel, the pulley and the reverse push wheel. However, it is limited by the thickness of the gap between the paper feed wheel and the pulley, and it can place paper in a single time. The quantity is small. If there are many paper documents to be processed, it will be necessary to put the paper several times to complete the processing of the documents. Therefore, there is a technical problem that the amount of paper fed is small and affects the processing efficiency.

The coding device 7 is respectively arranged above and below the output end of the paper conveying device 5, and the controller can be fixed on the lower part of the base 1, and is respectively connected with the paper feeding device 4, the paper conveying device 5, the image acquisition device 6 and the coding device 7 . in,

The paper feeding device 4 is used to convey the paper to be processed in pages to the paper conveying device 5, the paper conveying device 5 is used to convey the paper to be processed to the storage device 8 in sequence, and the image acquisition device 6 is used to separately collect the upper and lower sides of the paper during the paper conveying process. For the image on both sides, the controller is used to identify the image containing the characters, to arrange the page number values of the images containing the characters in order, to send the page number value to the coding device 7 to code the corresponding page of the corresponding paper, and to use After the coding is completed, the corresponding image is electronically coded and stored, and the storage device 8 is used to collect the paper after the coding is completed.

It should be noted that, the coding device 7 is used for coding the pages containing characters according to the page number value sent by the controller. For example, if the controller recognizes that the upper surface page of the paper to be processed contains characters, it will arrange the corresponding page number value for the page number, and then send the page number value to the upper coding device 7, and when the paper moves to the upper Coding is performed on the upper surface of the coding device 7 below, so as to realize the one-to-one correspondence between paper documents and converted electronic files.

In this embodiment, an image acquisition gap 9 is provided in the middle of the paper conveying device 5 for the convenience of the image capturing device 6 below. The glass plate/acrylic plate can play a role equivalent to the image acquisition gap 9 .

This embodiment does not limit the specific structures of the base 1, the paper feeding device 4, the paper conveying device 5, the storage device 8, the image acquisition device 6 and the coding device 7, which can be realized by using existing conventional structures, for example, coding The device 7 can be coded by an inkjet printer, and the storage device 8 can be a bracket with a foldable structure. As long as these conventional structures can be arranged according to the above structure, the paper documents can be intelligently sorted and coded, and finally the paper documents and the electronic file page numbers can be matched one by one.

It should be noted that the image acquisition device 6 in this embodiment can use an ordinary area scan camera or a line scan camera 16 to acquire images, but the specific equipment used to acquire images is also related to the length and width of the image acquisition gap 9 . For example, when using an ordinary area array camera to collect images, the length and width of the image collection gap 9 can be set slightly smaller than the length and width of the paper, so as to support the paper through the four sides of the paper. In this way, when the paper runs to the position of the image acquisition gap 9, the pages containing characters on the lower surface of the paper are all exposed in the window of the area array camera below, and at this time, the image of the lower surface of the paper can be collected by the area array camera .

However, although the above-mentioned common area array camera can also collect images, its image collection effect is average, and it is necessary to ensure that the length and width of the image collection gap 9 are larger, which will cause the overall size of the device to become larger, which is not conducive to the device. refinement and miniaturization, for this reason, this embodiment preferably adopts the line scan camera 16 to carry out image acquisition, on the one hand, this makes the image acquisition gap 9 with smaller size can realize the effective acquisition of images, on the other hand, also It can obtain images with better collection effect and higher quality without stopping the paper.

The controller in this embodiment has the above-mentioned processing function and storage function, etc., which can be realized in any suitable manner. Program code (such as software or firmware) in the form of computer-readable media, logic gates, switches, Application Specific Integrated Circuits (ASICs), programmable logic controllers, and embedded microcontrollers. Those skilled in the art also know that, in addition to realizing the controller in a purely computer-readable program code mode, it is entirely possible to make the controller use logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded The same function can be realized in the form of a microcontroller or the like. Therefore, such a controller can be regarded as a hardware component, and the devices included in it for realizing various functions can also be regarded as structures within the hardware component.
