Description

Technical Field

[0001] This utility model relates to the field of intelligent recognition technology, specifically to a text recognition device. Background Technology

[0002] Character recognition technology is the process of reading characters on paper and converting them into computer text using optical and computer technologies. It is an important technological link in the field of intelligent character recognition. By converting images and other data into text, information can be quickly recorded and stored on computers. As computer speeds increase, the requirements for the matching degree between the recognition results and the actual text characters also increase. However, the flatness of the surface of the object being measured has a significant impact on the accuracy of the character recognition results. At the same time, people need to process large amounts of text, reports, and documents in their production and daily life, and it is necessary to reduce people's labor and improve processing efficiency.

[0003] According to a text recognition device disclosed in Chinese Patent CN202021479636.6, this application includes a recognition device body, a worktable, and an adjusting rod. The recognition device body has a base welded to its bottom for support, and a worktable extending to the left and right ends is welded to the top of the base. A display screen is welded to the lower left end of the upper surface of the worktable, and a square groove is formed in the middle of the upper surface. A fixing device is welded to the left side of the square groove, and an adjusting rod is vertically welded to the middle of the rear end of the square groove. The adjusting rod has a height scale engraved on its front, and vertical grooves are formed in the middle of the left and right sidewalls. This invention solves the problems of limited functionality and low accuracy of text recognition results in existing intelligent text recognition devices, effectively improving the processing efficiency of intelligent text recognition devices. Existing intelligent text recognition devices use transparent glass to press and fix the paper. Because glass has a reflective effect, it affects the recognition accuracy of the camera. Furthermore, existing intelligent text recognition devices require manual height adjustment of the camera, which is laborious and time-consuming.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

The lead screw 14 drives two sets of moving blocks 15 to move closer or further apart. The two sets of moving blocks 15 then drive two sets of rotating plates 8 to move closer or further apart to achieve a suitable distance for the paper. Then, the rotating plates 8 are rotated so that the positioning groove 10 on the rotating plates 8 engages with the positioning iron post 11. At this time, the magnet 12 in the positioning groove 10 attracts the positioning iron post 11, fixing the rotating plates 8 in place. During this process, the rotating plates 8 drive the pressure block 9 to press and fix the sides of the paper. By setting up a paper fixing assembly, the paper can be fixed to prevent movement during text recognition. The paper fixing assembly includes the rotating plate, pressure block, positioning iron post, and... Magnets can be used to press and fix the paper on both sides without covering and pressing the entire paper, which does not affect the accuracy of text recognition and makes it more stable and reliable.

After the paper is fixed, recognition begins. At this time, servo motor 23 is started to drive lead screw 21 to rotate. Lead screw 21 drives moving block 22 to move up or down. Moving block 22 drives the recognition camera 5 to move up or down to the optimal recognition height through mounting block 4. The height adjustment component can be set to adjust the height of the recognition camera to achieve the optimal recognition height, improving recognition efficiency. At the same time, the height adjustment component is driven by a motor and does not require manual adjustment, which saves time and effort.

[0033] In summary, by utilizing the above-mentioned technical solution of this utility model, the paper fixing component can be used to fix the paper and prevent it from moving during text recognition. The rotating plate, pressure block, positioning iron column, and magnet in the paper fixing component work together to press and fix both sides of the paper, eliminating the need to cover and press the entire paper, thus not affecting the text recognition accuracy and making it more stable and reliable. The spacing adjustment component in the paper fixing component can adjust the spacing between the two sets of rotating plates to fix paper of different lengths, making it widely applicable. The height adjustment component can adjust the height of the recognition camera to achieve the optimal recognition height, improving recognition efficiency. At the same time, the height adjustment component is driven by a motor, eliminating the need for manual adjustment, which saves time and effort.
