In some embodiments, the number of cameras 311 may be multiple, and some cameras 311 are used to scan the document to be scanned, and other cameras 311 may be used to identify the identity of the operator, so as to associate the operator with the document to be scanned, and to give the operator appropriate authority. For example, compared with the student, the teacher may be given higher authority to facilitate the use of the correction device 100. The operator is a person who operates the correction device 100, and the operator may be a student or a teacher.

[0042] like Figure 4As shown, the scanning assembly 31 further includes a mounting bracket 312 , which can be adhered to the housing 22 by glue, and the camera 311 can be mounted on the mounting bracket 312 by screws, so as to install the camera 311 on the arm 2 .

[0043] The processor 32 is used to analyze the question information and answer information obtained by the scanning component 31 and generate a correction result. The question information and answer information can be analyzed by first performing text recognition on the scanned image to extract the text information, and then matching the text information with the data in the server to obtain the correction result through analysis.

[0044] The printing component 33 is used to print the correction results, for example, it can print the correction results on paper or other materials, so that students do not have to occupy the correction device 100 for learning, and the correction device 100 can be used by other people, thereby improving the utilization rate of the correction device 100; and the paper correction results are convenient for students to study, easy to view and write, which is conducive to improving students' learning efficiency. Optionally, the printing component 33 can be a thermal printer, and the printing medium is thermal printing paper. Optionally, one side of the printing medium has adhesive, and the printing medium can be attached to the scanned document or book, which is convenient for students to study and organize.

[0045] The display component 34 is used for displaying, for example, it can display a preview of the scanned image of the scanning component 31, so that the operator can adjust the position of the to-be-printed document to improve the scanning effect. The display component 34 can also display the correction results, so that they can be viewed directly on the display component 34. The display component 34 can also be touch-controlled, for example, the display component 34 includes a touch screen, so as to operate the correction device 100.

[0046] The near field communication component 35 is used to obtain information of identifiable objects at a short distance. For example, the near field communication component 35 is an NFC module, and the identifiable object is an NFC card. The information of the NFC card can be read by bringing the NFC card close to the NFC module. The NFC card can store the identification information of the operator, and the identification information can be a student ID number or an ID card number, so as to facilitate rapid identification of the operator's information and facilitate matching the operator with the scanned object, such as matching a test paper with a student.

[0047] The speaker 36 is used to make sounds, such as a prompt tone, which can prompt the operator to perform some operations. For example, it prompts the operator to straighten the scanned document, or prompts the operator that the printing component 33 lacks printing medium. Optionally, the speaker 36 is a horn.

[0048] For the above-mentioned base plate 1, if Figures 1 to 3 As shown, the bottom plate 1 can be in the shape of a rectangular plate to facilitate placing the scanned object. Optionally, the four corners of the bottom plate 1 are provided with rounded chamfers to reduce safety hazards.

[0049] Furthermore, if Figures 1 to 3 As shown, the bottom plate 1 includes a plate body 11 and an elastic layer 12. The elastic layer 12 is arranged on the top surface of the plate body 11. The elastic layer 12 is used to contact the object to be scanned to reduce the sliding of the object to be scanned on the bottom plate 1 and improve the comfort of taking and placing the object to be scanned. Optionally, the elastic layer 12 is made of silicone, and can be an antibacterial silicone layer, and the plate body 11 can be made of metal.

[0050] Furthermore, if Figure 1 and Figure 3 As shown, the top surface of the elastic layer 12 is convexly provided with a limit bar 121, and the limit bar 121 is used for the workpiece to be scanned to abut against, so as to facilitate the alignment of the workpiece to be scanned. The number of the limit bars 121 can be two, and the two limit bars 121 are arranged in parallel and spaced apart. In some other embodiments, the limit bar 121 can also be directly arranged on the plate body 11, that is, the bottom plate 1 includes the plate body 11, and the plate body 11 is provided with the limit bar 121.

[0051] For the above-mentioned vertical arm 2, if Figure 1 As shown, one end of the vertical arm 2 is connected to the bottom plate 1, and the other end extends above the bottom plate 1, so that when the electronic component 3 is installed on the vertical arm 2, it can be located above the bottom plate 1. Figure 2 and Figure 3 As shown, the scanning assembly 31 is disposed at one end of the vertical arm 2 away from the bottom plate 1 to increase the distance between the scanning assembly 31 and the bottom plate 1 and expand the scanning range of the scanning assembly 31 .

[0052] like Figure 2 and Figure 3 As shown, the arm 2 includes a support frame 21, a shell 22, a first cover plate 23 and a second cover plate 24. One end of the support frame 21 is connected to the bottom plate 1, and the other end extends above the bottom plate 1. The shell 22 is embedded in the support frame 21 to install the shell 22 on the bottom plate 1. Optionally, the shell 22 and the support frame 21 are fixed by glue.

[0053] For the above-mentioned support frame 21, Figure 2 and Figure 3 As shown, the support frame 21 may be in the shape of a rectangular frame. Optionally, the support frame 21 is detachably connected to the bottom plate 1 by screws, and the support frame 21 may be made of metal, such as aluminum alloy.

[0054] Furthermore, if Figure 2 and Figure 3As shown, the support frame 21 is provided with a first connection portion 211, which is in the shape of a rectangular plate, and a mounting groove 2111 is provided on the side of the first connection portion 211 facing the bottom plate 1. The bottom plate 1 is provided with a second connection portion 13, and the second connection portion 13 is adapted to the mounting groove 2111. For example, the shape and size of the second connection portion 13 are the same as the shape and size of the mounting groove 2111, which is conducive to increasing the stability of the connection between the support frame 21 and the bottom plate 1. Optionally, along the thickness direction of the bottom plate 1, the thickness of the first connection portion 211 is equal to the thickness of the bottom plate 1, so that the top surface of the first connection portion 211 is flush with the top surface of the bottom plate 1, so that the first connection portion 211 is smoothly connected to the bottom plate 1, which is conducive to enhancing the overall appearance of the correction device 100. Optionally, the second connection part 13 is located on the plate body 11 , the thickness of the second connection part 13 is equal to the thickness of the plate body 11 , and the sum of the thickness of the plate body 11 and the thickness of the elastic layer 12 is equal to the thickness of the first connection part 211 , so that the first connection part 211 is smoothly connected to the elastic layer 12 .

[0055] Furthermore, if Figure 2 and Figure 3 As shown, the second connection portion 13 is located at the edge of the base plate 1, that is, the support frame 21 is connected to the edge of the base plate 1, reducing the interference of the support frame 21 on the scanned object to increase the effective area on the base plate 1 that can be used to place the scanned object.

[0056] For the above-mentioned housing 22, if Figure 2 and Figure 3 As shown, the housing 22 includes a first section 221 and a second section 222; one end of the first section 221 is connected to the bottom plate 1, and the other end extends to the top of the bottom plate 1 along the first direction X; one end of the second section 222 is connected to the first section 221, and the other end extends along the second direction Y. Among them, the angle between the second direction Y and the bottom plate 1 is smaller than the angle between the first direction X and the bottom plate 1. Therefore, along the direction perpendicular to the first direction X, the second section 222 protrudes from the first section 221, and in the embodiment of the present application, the scanning component 31 is arranged in the second section 222, so the scanning component 31 is not easily blocked by the first section 221. It can be understood that the second section 222 is located on the side of the first section 221 facing the bottom plate 1 to avoid the scanning component 31 being blocked by the first section 221. Optionally, the angle between the first direction X and the bottom plate 1 is 80 degrees. Optionally, the first section 221 and the second section 222 are made of one piece. Optionally, along their extending direction, the cross-sections of the first section 221 and the second section 222 are both rectangular.

[0057] Furthermore, if Figure 2 and Figure 3As shown, the second section 222 is connected to the end of the first section 221 away from the bottom plate 1, and the scanning component 31 is arranged on the second section 222, that is, the scanning component 31 is arranged on the end of the vertical arm 2 away from the bottom plate 1, thereby further increasing the distance between the scanning component 31 and the bottom plate 1 and increasing the scanning area of ​​the scanning component 31.

[0058] In some embodiments, the first section 221 is adapted to the support frame 21, that is, the shape and size of the first section 221 are the same as the shape and size of the cavity in the support frame 21, so that the first section 221 can be stably installed on the support frame 21. The second section 222 extends out of the support frame 21 to reduce the shielding of the scanning component by the support frame 21.

[0059] like Figure 3 As shown, the housing 22 is provided with a receiving cavity 223, and the receiving cavity 223 is used to install the electronic component 3. Specifically, the scanning component 31, the processor 32, the printing component 33, the near field communication component 35 and the speaker 36 are all arranged in the receiving cavity 223. Figure 3 As shown, the housing 22 is further provided with a first opening 224, the first opening 224 is communicated with the accommodating cavity 223, and the first cover plate 23 is detachably provided on the first opening 224, so as to facilitate the disassembly and installation of the electronic component 3 in the accommodating cavity 223. Optionally, the first cover plate 23 is detachably connected to the housing 22 by screws, and the housing 22 is made of plastic. Optionally, the housing 22 and / or the first cover plate 23 are provided with a sound outlet hole, so that the sound of the speaker 36 can be transmitted outward.

[0060] like Figure 2 As shown, the housing 22 is further provided with a second opening 225, the second opening 225 is communicated with the accommodating cavity 223, the second cover plate 24 is detachably provided on the second opening 225, the printing assembly 33 is provided at the second opening 225, and is exposed outwardly from the second opening 225, so as to facilitate the printing assembly 33 to replace the printing medium. It can be understood that the second cover plate 24 is provided with a paper outlet 241 for outputting the printing medium. Optionally, the second cover plate 24 is made of plastic.

[0061] In some embodiments, the second cover plate 24 is magnetically connected to the housing 22, so that the second cover plate 24 is easy to assemble and disassemble. Figure 5 As shown, the electronic component 3 also includes an electromagnetic lock 37, Figures 1 to 4Not shown, the second cover plate 24 is magnetically connected to the housing 22 through an electromagnetic lock 37, and the electromagnetic lock 37 is electrically connected to the processor 32, so that the unlocking and locking of the second cover plate 24 can be controlled by the processor 32, which facilitates the disassembly and assembly of the second cover plate 24. For example, the operator's information can be identified through the near field communication component 35. If the operator is a teacher or a staff member, he has the authority to unlock the electromagnetic lock 37; then the authorized operator can control the correction device 100 through the display component 34, control the processor 32 to unlock the electromagnetic lock 37, and unlock the second cover plate 24; while the operator without authority, such as a student, cannot unlock the second cover plate 24, which is conducive to protecting the correction device 100 and improving the problem of students causing damage to the correction device 100.

[0062] Furthermore, if Figure 2 and Figure 3 As shown, the first opening 224 is located on the side of the shell 22 away from the bottom plate 1, and the second opening 225 is located on the side of the shell 22 facing the bottom plate 1. The first opening 224 and the second opening 225 are exposed at the two side openings of the support frame 21. As a result, the support frame 21 does not block the first opening 224 and the second opening 225, and the first cover plate 23 and the second cover plate 24 are not easily interfered by the support frame 21 during assembly and disassembly, which facilitates the assembly of the stand arm 2 and the assembly and disassembly of the first cover plate 23 and the second cover plate 24. Optionally, as Figure 3 As shown, when the first section 221 is in a rectangular shape, the first opening 224 and the second opening 225 are respectively located on two opposite outer surfaces of the first section 221, and the area of ​​the first opening 224 is equal to the area of ​​the outer surface, that is, the first opening 224 occupies the entire outer surface.

[0063] like Figure 3 As shown, the accommodating cavity 223 extends to the first section 221 and the second section 222, the printing assembly 33 is disposed in the first section 221, and the first opening 224 is located in the first section 221, so as to facilitate the disassembly and assembly of the printing assembly 33. It can be understood that since the printing assembly 33 is located in the first section 221, the second opening 225 is also located in the first section 221.

[0064] like Figure 2As shown, the housing 22 is further provided with a third opening 226 connected to the accommodating cavity 223. The scanning component 31 is disposed in the accommodating cavity 223 and is exposed outwardly at the third opening 226 so as to scan the object to be scanned through the third opening 226, that is, the scanning component 31 is illuminated through the third opening 226. It can be understood that the third opening 226 is located in the second section 222. Furthermore, the second direction Y is parallel to the bottom plate 1, and the side of the second section 222 facing the bottom plate 1 is parallel to the bottom plate 1. When the third opening 226 is opened at the side, the opening direction of the third opening 226 is directly facing the bottom plate 1, so that the scanning component 31 can scan the object to be scanned on the bottom plate 1 in a direction perpendicular to the bottom plate 1, which is conducive to improving the scanning effect.

[0065] Furthermore, if Figure 4 As shown, a limiting protrusion 227 is provided on the inner wall of the accommodating cavity 223, and the limiting protrusion 227 is adjacent to the third opening 226; the adjacent two sides of the scanning component 31 are respectively against the inner wall of the accommodating cavity 223 and the limiting protrusion 227 to limit the position of the scanning component 31, which is convenient for positioning when the scanning component 31 is installed. Optionally, the limiting protrusion 227 is provided at the opening of the fourth opening 228, and the number of the limiting protrusion 227 is multiple, for example, three. Optionally, the limiting protrusion 227 is in the shape of a rectangular parallelepiped.

[0066] Furthermore, if Figure 2 As shown, the arm 2 further includes a protection plate 25, which covers the third opening 226 and is located outside the housing 22 to protect the scanning assembly 31 in the accommodating cavity 223. Optionally, the protection plate 25 is a glass plate, and the protection plate 25 is glued to the housing 22. Optionally, the third opening 226 can be set as a stepped opening to facilitate installation and positioning of the protection plate 25.

[0067] like Figure 2 and Figure 4 As shown, the housing 22 is further provided with a fourth opening 228 connected to the accommodating cavity 223. The fourth opening 228 is located in the second section 222. The fourth opening 228 is used for the scanning assembly 31 to pass through and be installed in the accommodating cavity 223, thereby facilitating the disassembly and assembly of the scanning assembly 31. Furthermore, the display assembly 34 is covered on the fourth opening 228 to close the fourth opening 228, thereby eliminating the need for an additional cover plate, simplifying the structure of the grading device 100, and facilitating the electrical connection between the display assembly 34 and the processor 32 located in the accommodating cavity 223. Optionally, the angle between the opening direction of the fourth opening 228 and the bottom plate is an acute angle, for example, 15 degrees, and the opening direction of the fourth opening 228 is upward, so that when the display assembly 34 is covered on the fourth opening 228, the display assembly 34 faces obliquely upward, which is convenient for the operator to watch and operate.

[0068] Furthermore, if Figure 2 and Figure 4 As shown, a flange 2281 is provided at the fourth opening 228, and the display assembly 34 includes a display screen 341 and a mounting frame 342. The display screen 341 covers the fourth opening 228, and a portion of the mounting frame 342 is sleeved on the edge of the display screen 341, and another portion is sleeved on the flange 2281, so as to mount the display screen 341 on the housing 22.
