[0036] The support folding frame 3 is set to a "T"-shaped structure, and both sides of the support folding frame 3 are hinged with a mounting folding frame 5 through an upper hinge shaft 4. The rotation angle of the mounting folding frame 5 on the support folding frame 3 is ninety degrees. When the mounting folding frame 5 is in the initial position on the support folding frame 3, the support folding frame 3 and the mounting folding frame 5 are distributed in parallel, so that the support folding frame 3 and the mounting folding frame 5 can be folded on the base 1 at the same time, so as to facilitate carrying. When the support folding frame 3 is rotated ninety degrees and then vertically fixed on the base 1, the mounting folding frame 5 is rotated ninety degrees and then vertically fixed on the support folding frame 3, so that the mounting folding frame 5 and the base 1 remain parallel, so that the visual cameras 8 installed on the two sets of mounting folding frames 5 through the camera position adjustment mechanism 6 can scan the paper materials on the base 1;

[0037] The spacing between the two sets of folding racks 5 is equal to the length of the base 1, and the lengths of the two sets of folding racks 5 are equal to the width of the base 1, so that the camera position adjustment mechanism 6 can control the visual camera 8 above the base 1 to perform unique scanning, and the scanning range of the visual camera 8 can cover all the contents of the paper materials placed on the base 1;

[0038] The lower hinge shaft 2 and the upper hinge shaft 4 are inserted closely, and the user needs to exert force to control the rotation, so that the supporting folding frame 3 and the mounting folding frame 5 are fixed after each adjustment and will not be easily reset, thereby ensuring the stability of the device when in use;

[0039] Moreover, the base 1 and the supporting folding frame 3 are both designed as hollow frames, so that the weight of the base 1 and the supporting folding frame 3 is reduced, and it is convenient to carry and use;

[0040] The camera position adjustment mechanism 6 includes a mounting seat 61 installed on two groups of mounting folding frames 5, and mounting seats 61 are installed on both sides of the two groups of mounting folding frames 5, and mounting seats 61 and screw rods 63 are respectively inserted between two groups of limit rods 62 on the two groups of mounting folding frames 5. A steering gear 64 is fixedly connected to the surface of one group of mounting seats 61 with screw rods 63 inserted, and the output shaft of the steering gear 64 is in transmission connection with the screw rod 63, so that the steering gear 64 can drive the screw rod 63 to rotate, and a slide 65 is sleeved on the limit rod 62 and the screw rod 63. When the screw rod 63 rotates in the threaded hole set on the surface of the slide 65, the slide 65 can slide on the surface of the limit rod 62 and the screw rod 63, and the sliding track of the slide 65 is along the mounting folding frame 5, so that the slide 65 can slide longitudinally above the base 1 to change its position;

[0041] The surface of the slide 65 is provided with two groups of protrusions and a screw rod 66 is inserted between the two groups of protrusions. At the same time, a fixedly connected limit strip 67 is provided on the surface of the slide 65 above the screw rod 66, and a slider 68 is sleeved on the surface of the screw rod 66. The limit grooves on the surface of the slider 68 are adapted to the size of the limit strip 67. A servo 69 is fixedly connected to the protrusions on the surface of the slide 65. The output shaft of the servo 69 is transmission-connected to the screw rod 66. The screw rod 66 is driven by the servo 69 to rotate in the threaded hole on the surface of the slider 68, so that the slider 68 can slide on the slide 65, and further the slider 68 can slide horizontally on the surface of the base 1 to change its position.

[0042] Through the structural setting of the camera position adjustment mechanism 6, the visual camera 8 installed on the camera position adjustment mechanism 6 can move horizontally and vertically above the base 1, so that the visual camera 8 can perform a comprehensive scan of the paper materials placed on the surface of the base 1;

[0043] And the servo 1 64 and the servo 2 69 can rotate forward and backward, so that the visual camera 8 can move back and forth above the base 1, which is convenient for adjusting and resetting the position of the visual camera 8;

[0044] Through the structural setting of the camera position adjustment mechanism 6, the visual camera 8 can be moved and adjusted above the base 1, and can be moved continuously, so that the continuity of the visual camera 8 in the scanning and analysis process can be guaranteed, thereby improving the accuracy of the scanning and analysis results. At the same time, the structural setting of the camera position adjustment mechanism 6 is all operated by electronic control, so that the displacement of the visual camera 8 during the movement process is more accurate, without the need for manual operation, thereby improving the efficiency of scanning and analysis;

[0045] The visual camera 8 is installed on the camera position adjustment mechanism 6 through the camera angle adjustment mechanism 7. The camera angle adjustment mechanism 7 includes a mounting shaft 1 71 inserted on the slider 68. One end of the mounting shaft 1 71 is fixedly connected to a turntable 72. At the same time, a steering gear 3 73 is fixedly connected to the slider 68. The output shaft of the steering gear 3 73 is transmission-connected to the mounting shaft 1 71, so that the steering gear 3 73 can drive the mounting shaft 1 71 to connect to the turntable 72 to rotate, thereby adjusting the inclination angle of the turntable 72 on the slider 68;

[0046] Meanwhile, a second mounting shaft 74 is inserted on the surface of the turntable 72, and a rotating block 75 is fixedly connected to one end of the second mounting shaft 74. A fourth steering gear 76 is also fixedly connected to the surface of the turntable 72. The output shaft of the fourth steering gear 76 is transmission-connected to the second mounting shaft 74, so that the fourth steering gear 76 can drive the second mounting shaft 74 to rotate in connection with the rotating block 75, thereby adjusting the tilt angle of the rotating block 75 on the turntable 72.

[0047] The visual camera 8 is fixedly connected to the rotating block 75. When the turntable 72 and the rotating block 75 are kept horizontal, the visual camera 8 is placed horizontally above the base 1. The paper material on the surface of the base 1 can be scanned and analyzed by the visual camera 8, and the camera position adjustment mechanism 6 can drive the visual camera 8 to adjust the position. When the steering gear 4 76 drives the rotating block 75 to rotate, the visual camera 8 can adjust the longitudinal angle. When the steering gear 3 73 drives the turntable 72 to rotate, the visual camera 8 can adjust the lateral angle.

[0048] In summary, by setting the camera position adjustment mechanism 6 and the camera angle adjustment mechanism 7, the visual camera 8 can perform a bidirectional reciprocating motion in the horizontal and vertical directions above the base 1, so as to quickly scan and analyze the paper materials placed on the base 1, and in the analysis process, when the surface content of the paper materials is unclear due to surface creases, mildew stains, etc., the camera angle adjustment mechanism 7 drives the visual camera 8 to adjust the angles in two dimensions, so that the visual camera 8 can form different angles to scan and analyze unclear content, thereby performing more accurate scanning and analysis of the content, and improving the accuracy of the scanning and analysis results, and the visual camera 8 can repeat the scanning multiple times through the electronic control operation of the camera position adjustment mechanism 6 and the camera angle adjustment mechanism 7, and then compare the scanning results, so as to further improve the accuracy of the scanning results;

[0049] A controller is installed inside the visual camera 8, which includes a control module, a Bluetooth communication module and a data storage module. The scanning analysis data stored in the data storage module can be transmitted to smart devices such as mobile phones and tablets through the Bluetooth communication module;

[0050] The four corners of the surface of the base 1 are fixedly connected with a paper driving mechanism 9. When the folding frame 5 is folded, it will contact the paper driving mechanism 9. The folding frame 5 is supported by the paper driving mechanism 9. The surface device is squeezed and damaged by external force. The surface of the paper driving mechanism 9 is fixedly connected with a rubber pad 10. The rubber pad 10 can contact the paper driving mechanism 9 and the surface of the folding frame 5, so that the rubber pad 10 buffers the collision force during folding to avoid friction damage. At the same time, the camera position adjustment mechanism 6, the camera angle adjustment mechanism 7 and the visual camera 8 are all detachable, which is convenient for carrying the entire device;

[0051] The paper driving mechanism 9 includes a mounting block 91 at the corner of the mounting base 1, a driving groove is provided on the surface of the mounting block 91, and a connecting shaft 1 92 is inserted on the upper inner wall of the driving groove, and a rolling wheel 93 is fixedly connected to the surface of the connecting shaft 1 92, and a steering gear 5 94 is fixedly connected to the surface of the mounting block 91, and the output shaft of the steering gear 5 94 is transmission-connected with the connecting shaft 1 92, so that the steering gear 5 94 can drive the connecting shaft 1 92 to connect the rolling wheel 93 to rotate in the driving groove, and a sliding groove is provided on the inner wall of the driving groove below the connecting shaft 1 92, and a limiting block 95 is inserted in the sliding groove, and a connecting shaft 2 96 is inserted in the limiting block 95, and a driven wheel 97 is fixedly connected to the surface of the connecting shaft 2 96, and the driven wheel 97 is located below the rolling wheel 93, and a reset spring 98 is fixedly connected to the bottom surface of the limiting block 95, and the other end of the reset spring 98 is fixedly connected to the inner wall of the mounting block 91;

[0052] When the paper material needs to be scanned, the paper material is inserted into the two sets of paper driving mechanisms 9 on the same side of the base 1. The paper material is first inserted into the driving groove on the surface of the mounting block 91, and according to the thickness of the paper material, the driven wheel 97 can be pressed downward to change the spacing between the driven wheel 97 and the rolling wheel 93, so that the driven wheel 97 is connected to the connecting shaft 2 96 to press the limit block 95 downward in the slide groove. The inner walls of the slide groove on both sides of the mounting block 91 are provided with limit grooves, and the surface of the limit block 95 is provided with two sets of limit protrusions and the limit grooves are adapted so that the limit block 95 The paper material can slide up and down in the slide groove until it is inserted between the rolling wheel 93 and the driven wheel 97. At this time, the hand is released, and the limit block 95 is reset under the elastic force of the reset spring 98, so that the driven wheel 97 slides upward, and further the driven wheel 97 and the rolling wheel 93 are pressed against the upper and lower surfaces of the paper material and clamped, and then the rolling wheel 93 is driven to rotate by the steering gear 5 94. During the rotation of the rolling wheel 93, the friction force can push the paper material forward, so that the paper material is automatically laid flat on the surface of the base 1, which is convenient for the visual camera 8 to scan and analyze;

[0053] At the same time, paper drive mechanisms 9 are arranged on both sides of the base 1, so that the four groups of paper drive mechanisms 9 can clamp and straighten the paper material, thereby reducing the influence of surface creases on the scanning and analysis results of the visual camera 8, and after the four groups of paper drive mechanisms 9 clamp the paper material, the steering gear 5 94 is turned on at the same time to move, so that the paper material can move laterally on the surface of the base 1, so that for some longer paper materials, the visual camera 8 can perform continuous scanning and analysis without interruption, and improve the scanning efficiency, avoiding the need for multiple position adjustment, folding and scanning of longer paper materials, which is easy to cause damage to the paper material;

[0054] The surfaces of both sides of the base 1 are provided with limit slots, the surface of the mounting block 91 is provided with threaded holes and limit bolts 99 are inserted into the threaded holes. The size of the limit bolts 99 is adapted to the limit slots on the surface of the base 1, so that after the mounting block 91 slides on the surface of the base 1 to change its position, the limit bolts 99 abut against the limit slots, so that the position of the mounting block 91 can be fixed, and the spacing between the two sets of paper driving mechanisms 9 can be adjusted, so as to facilitate the clamping and fixing of different paper materials;

[0055] Furthermore, by setting the paper driving mechanism 9, it is possible to scan and analyze paper materials, and to scan information on other flat materials such as wood, metal materials, etc., thereby improving the applicability of the device;

[0056] At the same time, a large area of ​​the interior of the base 1 is left empty, so that some smart devices can be placed in the middle of the base 1 for scanning.
