Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 7 , the present utility model provides a technical solution: a certificate recognition device based on OCR technology, including a recognition board 1, and smoothing components 2 are arranged on both sides of the recognition board 1; the smoothing component 2 includes a notch one 201, and the notch one 201 is opened on both sides of the top of the recognition board 1. A bracket 202 is fixedly connected to the inner wall of one side of the notch one 201. One side of the bracket 202 is movably connected by a hinge to an extension board one 203. The other end of the extension board one 203 is movably connected by a hinge to an extension board two 204.

A magnet one 208 is fixedly connected to one side of the smoothing plate 207, and a magnet two 209 is fixedly connected to the top of the recognition board 1. When recognizing an open-type paper certificate, first place the certificate on the recognition board 1 and spread it out. Then, by moving the smoothing plate 207 outwards, the movement of the smoothing plate 207 drives the support rod one 206 to move, and then through the extension frame 205, the extension board one 203 and the extension board two 204 are moved, so that the extension length of the smoothing plate 207 can be adjusted according to the size of the paper certificate. Then, through the magnetic force between the magnet one 208 and the magnet two 209, the opened paper certificate can be fixed.

[0024] In this embodiment, as Figure 3 and Figure 6As shown in the figure, an adjustment component 3 is provided at the top of the other side of the identification board 1. The adjustment component 3 includes an adjustment column 301. The adjustment column 301 is fixedly connected to the top of the other side of the identification board 1. Adjustment plates 302 are fixedly connected to the inner walls on both sides of the adjustment column 301. An extension column 303 is movably connected inside the adjustment column 301. One end of the extension column 303 is fixedly connected to an adjustment box 304. An adjustment rod 305 is movably connected inside the adjustment box 304 and the adjustment rod 305 passes through the adjustment box 304. A fixed ring 306 is fixedly sleeved on the outer wall of the adjustment rod 305. A spring 307 is fixedly connected to one side of the fixed ring 306 and the spring 307 is movably sleeved on the outer wall of the adjustment rod 305. One end of the adjustment rod 305 is fixedly connected to a clamping plate 308. Before use, first pull the adjustment column 301. The movement of the adjustment column 301 causes the clamping plate 308 to move between the adjustment plates 302. At the same time, the adjustment rod 305 is contracted through the spring 307, so that the clamping plate 308 can move into the interval between the next adjustment plates 302. After use or when disassembly is required, just pull the extension column 303 and pull it out of the adjustment column 301.

[0025] In this embodiment, as Figure 7 shown, an identification component 4 is provided on one side of the extension column 303. The identification component 4 includes a second support rod 401. The second support rod 401 is fixedly connected to one side of the extension column 303. A notch 402 is provided on one side of the second support rod 401. Resistance rings 403 are fixedly connected to the inner walls on both sides of the notch 402. A percussion groove 404 is provided on one side of the resistance ring 403. A hole 405 is provided on one side of the second support rod 401. A movable shaft 406 is movably connected inside the hole 405. A transmission wheel 407 is fixedly sleeved on the outer wall of the movable shaft 406. Percussion plates 408 are fixedly connected to both ends of the transmission wheel 407. One end of the movable shaft 406 is fixedly connected to a rotary knob 409. A connecting column 410 is fixedly connected to the side surface of the transmission wheel 407. A camera 411 is fixedly connected to one end of the connecting column 410. A lighting lamp 412 is fixedly connected to one end of the connecting column 410. When the size of the paper certificate is large, by rotating the rotary knob 409 to rotate the movable shaft 406, the transmission wheel 407 can be driven to rotate in the notch 402, so as to adjust the angles of the camera 411 and the lighting lamp 412, so that it can more completely photograph and identify the paper certificate on the identification board 1. While the transmission wheel 407 is rotating, the percussion plates 408 can strike on the percussion groove 404 to emit sounds, so that the adjustment angle can be judged by the interval between the sounds, and the resistance rings 403 can prevent the angles of the camera 411 and the lighting lamp 412 from shifting.

[0026] The usage method and advantages of the present utility model: For this certificate identification device based on OCR technology, during use, the working process is as follows:

[0027] As Figure 1 、Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in Figure 6 , Figure 7 , when identifying a folding paper document, first place the document on the identification board 1 and unfold it. Then, by moving the flattening plate 207 outwards, the movement of the flattening plate 207 drives the movement of the first support rod 206. Through the extension frame 205, the first extension plate 203 and the second extension plate 204 move, enabling the length of the extension of the flattening plate 207 to be adjusted according to the size of the paper document. Then, through the magnetic force between the first magnet 208 and the second magnet 209, the opened paper document can be fixed. Before use, first pull the adjustment column 301. The movement of the adjustment column 301 causes the clamping plate 308 to move on the adjustment plate 302. At the same time, the adjustment rod 305 is contracted through the spring 307, so that the clamping plate 308 can move into the interval between the next adjustment plates 302. After use or when disassembly is required, just pull the extension column 303 and pull it out of the adjustment column 301. When the size of the paper document is large, by rotating the rotary knob 409, the movable shaft 406 rotates, which can drive the transmission wheel 407 to rotate in the second notch 402, and then the angles of the camera 411 and the lighting lamp 412 can be adjusted, enabling a more complete photographing and identification of the paper document on the identification board 1. While the transmission wheel 407 is rotating, the knocking plate 408 can knock on the knocking groove 404 to emit a sound, enabling the adjustment angle to be judged based on the interval between the sounds. And through the resistance ring 403, the angles of the camera 411 and the lighting lamp 412 can be prevented from shifting.
