[0027] The following is a detailed description of an embodiment of the document information collection device of the present invention. Please refer to [link / reference]. Figures 1 to 5 It includes:

[0028] A main frame 201 is provided with a page-turning mechanism 100. The page-turning mechanism 100 includes: a visual imaging platform 101 movably mounted on the main frame 201, which can move back and forth on the main frame 201 and is slightly higher than the plane of the main frame 201; the visual imaging platform 101 has a document holding slot 102 for holding an opened booklet document; the front end of the visual imaging platform 101 has a forward-protruding page-turning block 104 for turning the pages of the opened booklet document; and the information collection station 203 of the main frame 201 is located directly above it. A shooting device 400 is provided, and the visual shooting platform 101 is located below the shooting device 400 and connected to the information acquisition station 203 on the main frame 201. Therefore, the shooting device 400 can collect the page information of the opened document in the document holding position 102. The information acquisition station 203 is provided with a document clamping mechanism 500 for clamping the document. By clamping the document, when the page turning block 104 turns the document, the document will not move forward with the visual shooting platform 101, ensuring the smooth operation of the page turning.

[0029] The specific working principle of this document information collection device is as follows: The document is first sent into the information collection station 203 of the main frame 201. The document clamping mechanism 500 clamps the bottom surface of the document. Then, the visual shooting platform 101 moves from back to front and stops on the information collection station 203. During the forward movement of the visual shooting platform 101, the page-turning block 104 at its front end will contact the page that is turned up in the document and drive the page to turn forward together. When the visual shooting platform 101 reaches the information collection station 203 and stops moving, the turned document is just in the document receiving position 102. Then, the shooting device 400 will take a picture of the turned page to collect its image content.

[0030] In this embodiment, the document receiving position 102 is covered by a transparent cover plate 103; the upper surface of the document clamping mechanism 500 is provided with a lifting plane 501; the lifting plane 501 is smaller than the area of ​​the document receiving position 102, and the lifting plane 501 can extend into the document receiving position 102 from below. Therefore, when the flipped document is fully inserted into the document receiving position 102, the lifting plane 501 will lift upward, so that the flipped pages of the document are all pressed against the lower surface of the transparent cover plate 103, so that the flipped pages of the document can be in a flat state under the restriction of the transparent cover plate 103, which facilitates the image acquisition by the shooting device 400; therefore, the acquired image has low distortion rate and complete information.

[0031] In this embodiment, the visual imaging platform 101 is movably mounted on the first guide rail 202 of the main frame 201. There are two first guide rails 202, which are respectively arranged on both sides of the main frame 201. The main frame 201 is provided with a platform moving motor 107, which is connected to the visual imaging platform 101 through a transmission component. Therefore, driven by the platform moving motor 107, the visual imaging platform 101 can move back and forth along the first guide rail 202 on the main frame 201, so that the visual imaging platform 101 enters or leaves the information acquisition station 203 to realize the automatic page turning operation.

[0032] In this embodiment, the main frame 201 is provided with a second guide rail 205 parallel to the first guide rail 202. The document clamping mechanism 500 is movably mounted on the second guide rail 205, and the second guide rail 205 is disposed between the placement station 204 and the information collection station 203 of the main frame 201. Its specific working principle is as follows: In its initial state, the document clamping mechanism 500 is located in the placement station 204. When a physical document is placed on the document clamping mechanism 500 in the placement station 204, the document clamping mechanism 500 clamps the physical document and moves it along the second guide rail 205 to the information collection station 203 for page turning and information collection. After the page turning and information collection are completed, the document clamping mechanism 500 moves the physical document back to the placement station 204.

[0033] In this embodiment, a folding mechanism 300 is provided in front of the visual shooting platform 101. The folding mechanism 300 is equipped with a folding motor 303. The folding motor 303 is connected to one side of the folding block 305 through a swing block 304. The other side of the folding block 305 is hinged to the main body of the folding mechanism 300. The folding block 305 is equipped with a suction cup mounting seat. The suction cup mounting seat is equipped with a rotary motor 306. The rotary motor 306 is connected to the folding suction cup 301 through a swing member 307. The folding suction cup 301 cooperates with the page-turning block 104 in the visual shooting platform 101. After the document enters the information collection station 203, the folding motor 303 controls the folding block 305 to swing downwards, so that the folding suction cup 301 contacts the page to be turned. Then, the folding suction cup 301 holds the page, and then drives the folding motor 303 in the reverse direction, so that the folding suction cup 301 drives the page to turn up. At the same time, it drives the rotary motor 306, which drives the folding suction cup 301 to rotate a certain angle, folding the page at an angle to prevent multiple pages from being attracted, so that only one sheet of paper is attracted at a time. The folding mechanism 300 uses the folding suction cup 301 to lift the page to be turned up to an angle. Then, the vision shooting platform 101 moves forward, so that the page turning block 104 pushes the attracted page to turn the page. The folding suction cup 301 is connected to the vacuum generation module 700, which provides negative pressure for the folding suction cup 301.

[0034] In this embodiment, a slide rail 302 extends forward from the front end of the visual shooting platform 101, and the folding mechanism 300 is movably mounted on the slide rail 302. Therefore, the folding mechanism 300 can move back and forth in front of the visual shooting platform 101. When it is necessary to lift the page, the folding mechanism 300 moves closer to the visual shooting platform 101 to lift the page; when the visual shooting platform 101 needs to turn the page, the folding mechanism 300 moves away from the visual shooting platform 101 to avoid it.

[0035] In this embodiment, a rotatable brush 105 is provided on one side of the page-turning block 104, and the brush 105 is connected to the brush motor 106 on the visual imaging platform 101. The document in the information acquisition station 203 can have the page to be turned up picked up by the folding mechanism 300, and then the brush 105 will brush down the page that was turned up along with it, ensuring that the page-turning block 104 only turns up the picked-up page each time, preventing multiple page turns.

[0036] In this embodiment, one side of the transparent cover 103 is hinged to the visual imaging platform 101, and the other side of the transparent cover 103 is fixed to the visual imaging platform 101 by a locking member 108. Therefore, the transparent cover 103 can be rotated and opened by manually removing the locking member 108, which facilitates cleaning, replacement, and troubleshooting of the transparent cover 103.

[0037] In this embodiment, the document clamping mechanism 500 has upwardly extending gripper assemblies 502 along its edge, and a fixing suction cup 503 is provided on the lifting plane 501 of the document clamping mechanism 500. There are two sets of gripper assemblies 502, each set consisting of two opposing gripper pieces. These gripper pieces are positioned at the four corners of the document clamping mechanism 500, thus securing the four corners of the opened document. The lifting plane 501 also contains the fixing suction cup 503, which is located in the placement area of ​​the bottom surface of the document. This suction cup can cooperate with one set of gripper assemblies 502 to secure the bottom surface of the document, while the other set of gripper assemblies 502 secures the opened cover. The fixing suction cup 503 is connected to a vacuum generating module 700, which provides negative pressure to the fixing suction cup 503.

[0038] In this embodiment, the document information collection device further includes a supplementary lighting lamp 600 disposed above the main unit frame 201. This supplementary lighting lamp 600 makes the collected document page image clearer, thus meeting the information collection requirements.
