[0002] With the development of the economy, more and more enterprises and administrative units have more frequent financial circulation, which has led to the rapid development of office supplies. Among them, the work of organizing materials will take up a lot of time and energy of the staff, especially the financial voucher accounting work in financial management. Every company is involved in a large amount of financial voucher accounting work every month. In order to standardize the management of the financial accounting system, the process of financial voucher accounting is relatively more complicated. Since there are many types of financial vouchers, the amount of data is large, and the classification and pasting process is boring and monotonous, organizing financial voucher materials requires a lot of time and energy of the accountant, and the error rate is high. In order to overcome the above problems, an automatic financial voucher sorting machine has been developed to realize the automatic integration and pasting of financial vouchers, thereby improving the accounting efficiency. However, since financial vouchers are paper materials, wrinkles are inevitable during the storage process. If wrinkled financial vouchers are distributed together with ordinary financial vouchers and placed in a financial voucher classification box, they are prone to secondary bending in the financial voucher classification box due to the squeezing of other financial vouchers and are easily damaged. At the same time, they will be stuck in the financial voucher classification box due to the accumulation of other financial vouchers, causing the financial voucher classification box to be blocked.

[0012] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0013] like Figures 1 to 5 As shown, an embodiment of the present invention provides a financial certificate intelligent storage system based on three-dimensional coordinate positioning, which includes a financial certificate intelligent storage device and an image recognition module.

[0014] The financial certificate intelligent storage device includes a financial certificate placement platform 1, a financial certificate adsorption and adjustment component 2, a financial certificate transfer guide rail 5, a financial certificate transfer seat 6 and a financial certificate storage platform 7.

[0015] The financial certificate adsorption and adjustment component 2 is arranged just above the financial certificate placement platform 1. The financial certificate adsorption and adjustment component 2 includes at least a rotating component, a telescopic component and an adsorption component. The steering end of the rotating component can rotate around the horizontal axis toward the side of the financial certificate transfer guide rail 5. The fixed end of the telescopic component is fixedly connected to the steering end of the rotating component. The adsorption component is fixedly arranged at the movable end of the telescopic component. Figure 3As shown, the financial certificate adsorption adjustment component 2 includes a first rotating component 21, a second rotating component 22, a third rotating component 23, a fourth rotating component 24, a first telescopic component 25 and a first adsorption component 26; the first rotating component 21 can rotate about the vertical axis; the second rotating component 22 is provided with a planar base, and a rotating hinge end portion extends vertically upward from the center position of the planar base, and the rotating hinge end is hinged to the first rotating component 21 and can rotate about the horizontal axis toward the side of the financial certificate transfer guide rail 5; one end of the third rotating component 23 It rotates around a base axis that is perpendicular to the planar base, and the other end is hinged to the fourth rotating component 24; the fourth rotating component 24 includes a first division and a second division that are perpendicular to each other, the free end of the first division is hinged to the other end of the third rotating component 23 and can rotate around the base axis, the second division extends along the base axis, and is provided with a first guide rail that is parallel to the base axis; the first telescopic component 25 includes a lifting rod that is slidably mounted on the first guide rail through a slider, and the first adsorption component 26 is fixedly arranged at the lower end of the lifting rod.

[0016] The financial certificate transfer guide rail 5 is vertically arranged on one side of the financial certificate placement platform 1, and the financial certificate transfer seat 6 is movably mounted on the financial certificate transfer guide rail 5. Figure 1 and Figure 2 As shown, the financial certificate transfer seat 6 is provided with two transfer guide grooves 61 parallel to each other and horizontally arranged on one side relative to the financial certificate placement platform 1. Each of the transfer guide grooves 61 is provided with a second adsorption component 62. The second adsorption component 62 has an independent sliding drive component and can slide freely along the track. Specifically, the inner side of the transfer guide groove 61 of the financial certificate transfer seat 6 is provided with an air pump slide rail parallel to it. The second adsorption component 62 is movably mounted on the air pump slide rail through a slider, so that the air pump realizes the movement of the second adsorption component 62 in the transfer guide groove 61.

[0017] The financial certificate storage platform 7 is arranged at the end of the travel of the financial certificate transfer guide rail 5. Figure 4As shown, the financial document storage platform 7 is also equipped with two parallel and horizontal transfer guide grooves 61. Each transfer guide groove 61 is evenly distributed on both sides, with multiple embedded suction ports 72. The suction ports 72 are divided into multiple independently controlled units along the length of the horizontal guide rail according to the minimum width of the financial document. Each suction port 72 within a unit area can be connected to the same negative pressure pump via a suction channel provided within the platform. When the financial document transfer seat 6 moves to the end of the travel of the financial document transfer guide rail 5, the transfer guide groove 61 on the financial document transfer seat 6 aligns with the storage guide groove 71 on the financial document storage platform 7, and the air pump slide rail on the financial document transfer seat 6 aligns with the air pump slide rail on the financial document storage platform 7.

[0018] like Figure 5 As shown, the image recognition module includes a light emitting unit 41, a picture acquisition unit 42, a position recognition unit 43, a grayscale conversion unit 44 and a grayscale judgment unit 45; the light emitting unit 41 includes an ambient light source 411, as shown in FIG. Figure 2 As shown, the ambient light source 411 is an LED light array provided on one side of the financial voucher placement platform 1. The LED light array provides ambient light for the financial voucher from the side of the financial voucher placement platform 1. If there are wrinkles on the financial voucher, the portion on the backlight side of the wrinkle will produce a shadow under the ambient light provided by the LED light array. Based on the difference between the wrinkled portion and the flat portion, it is preliminarily determined whether the financial voucher has wrinkles. The image acquisition unit 42 is provided above the financial voucher placement platform 1 and is used to capture images of the financial voucher on the financial voucher placement platform 1. The image acquisition unit 42 can use a CCD camera. The position recognition unit 43 is used to recognize the position of the financial voucher based on pre-stored shape and size and in combination with a three-dimensional coordinate system. That is, a three-dimensional coordinate system is established for the financial voucher placement platform 1, and then the financial voucher is identified according to the pre-stored shape and size, and then the specific position of the financial voucher is calculated by the three-dimensional coordinate system; the grayscale conversion unit 44 is used to convert the collected image into a grayscale image. When there are wrinkles on the financial voucher, the part on the backlight side of the wrinkle will produce a shadow under the unilateral light provided by the LED light array. After the grayscale conversion is performed in the image collected by the image acquisition unit 42, the grayscale value of the pixel at the wrinkle position is higher than the grayscale value of the plane position; the grayscale judgment unit 45 is used to compare the pixel grayscale value of the grayscale image according to the set grayscale threshold, and judge whether there is a wrinkle in the financial voucher based on the judgment condition that the pixel grayscale value at the wrinkle position is higher than the set grayscale threshold.

[0019] In order to further determine the existence of wrinkles, the light emitting unit 41 further includes a background light source 412 arranged in the direction of the light source, such as Figure 2As shown, the background light source 412 is provided on a horizontal adjustment arm 413. The horizontal adjustment arm 413 can be any existing mechanical arm capable of performing telescopic and / or lateral and / or longitudinal displacement adjustment on a horizontal plane, such as Figure 2 As shown, the embodiment of the present invention utilizes a linkage robotic arm comprising a first linkage and a second linkage. One end of the first linkage is pivotally connected to a fixed point, and the other end is pivotally connected to the second linkage. The first linkage can rotate about the fixed point, and the second linkage can rotate about the other end of the first linkage, thereby achieving horizontal position adjustment. A background light source 412 provides upward illumination from the back of the financial document. The high-brightness background light reduces the transmittance of wrinkled areas. The difference between wrinkled areas and flat areas allows for a secondary determination of whether the document has wrinkles. When not in operation, the background light source 412 automatically retracts to a hidden position set to one side, and its height is lower than the maximum travel end of the lifting rod. Furthermore, the background light source 412 utilizes a multi-color LED to provide multi-color background illumination for the financial document. Based on a multi-color compensation scanning method, different colored lights provide different wavelengths and bands to scan the information on the financial document. Grayscale recognition and modeling are performed on each scanned information, and the confirmed financial document information is determined by matching it with image data of standard characters.

[0020] When a financial certificate is placed on the financial certificate placement platform 1, the LED light array is turned on and the CCD camera starts to collect image information. The grayscale conversion unit 44 converts the collected image into grayscale and determines whether there are wrinkles on the financial certificate based on the grayscale value. If there are wrinkles on the financial certificate, the part on the backlight side of the wrinkle will produce a shadow under the unilateral light provided by the LED light array. The pixel grayscale values of the grayscale image are compared according to the set grayscale threshold. Based on the judgment condition that the pixel grayscale value at the wrinkle position is higher than the set grayscale threshold, a preliminary judgment is made as to whether there are wrinkles on the financial certificate.

[0021] If it is preliminarily determined that there are wrinkles on the financial document, the financial document adsorption adjustment component 2 is adjusted according to the position of the financial document, that is, by adjusting the rotation angles of the third rotating component 23 and the fourth rotating component 24, the four first adsorption components 26 are made to face the four top corners of the financial document. Then, the first adsorption components 26 are started to adsorb the financial document, and the lifting rod is driven to lift the financial document.

[0022] Next, background light source 412 extends from a hidden position on one side via a transverse telescopic component and, through the coordination of the transverse telescopic arm and the longitudinal guide rail, moves to below the fold, providing high-brightness background light for the fold. Under the influence of the high-brightness background light, the transmittance of the crease or fold is low. By recapturing the image of the financial document under the background light, grayscale recognition is used to accurately determine whether the financial document has wrinkles. To avoid the problem of positioning accuracy being affected by the precision of the hardware equipment, the background light source 412 can also be moved within a small range around the positioning point along a set trajectory after being positioned below the fold, through the coordination of the transverse telescopic arm and the longitudinal guide rail.

[0023] When it is determined that there is a wrinkle on the financial document, the second rotating component 22 of the financial document adsorption and adjustment component 2 is controlled to rotate with the wrinkled financial document toward the side of the financial document transfer guide rail 5, and the financial document is sent to a position close to the financial document transfer guide rail 5. Then, the second rotating component 22 rotates toward the side of the financial document transfer guide rail 5 around the horizontal axis, so that one side of the financial document is lifted and approaches the side of the financial document transfer seat 6 set on the financial document transfer guide rail 5. At the same time, the second adsorption component 62 on the financial document transfer seat 6 is activated and the first adsorption component 26 on the side of the financial document adsorption and adjustment component 2 close to the financial document transfer seat 6 is closed. Then, the end of the financial document close to the financial document transfer seat 6 is adsorbed to the financial document transfer seat 6 under the action of negative pressure adsorption. Then, the first adsorption component 26 on the side of the financial document adsorption and adjustment component 2 away from the financial document transfer seat 6 is closed, so that the other end of the financial document is vertically attached to the financial document transfer seat 6 under the action of adsorption force, gravity and tortuosity recovery force, and the financial document adsorption and adjustment component 2 returns to its initial state.

[0024] After the folded financial certificate is transferred to the financial certificate transfer seat 6, the financial certificate transfer seat 6 moves upward to the end point of the travel of the base transfer guide rail and connects with the financial certificate storage platform 7. The folded financial certificate is adsorbed by the second adsorption component 62 on the financial certificate transfer seat 6 and moves along the air pump slide rail to the financial certificate storage platform 7. The adsorption port 72 on the financial certificate storage platform 7 generates negative pressure to adsorb the financial certificate. The freely movable second adsorption component 62 stops working, completing the transfer of the folded financial certificate to the financial certificate storage platform 7. The second adsorption component 62 returns to the financial certificate transfer seat 6. The financial certificate transfer seat 6 falls to the initial position and waits for the transfer of the next folded financial certificate. The folded financial certificate always remains in a vertical state under the action of the upper and lower adsorption ports 72 and will not be bent twice. The subsequent folded financial certificates are arranged in sequence along the storage guide groove 71 and adsorbed and stored on the financial certificate storage platform 7. When the folded financial certificate needs to be pasted, it returns to the financial certificate placement platform 1 along the original path.

[0025] The present invention transfers wrinkled financial documents to the financial document transfer seat 6 by cooperating between the financial document adsorption adjustment component 2 and the adsorption component on the financial document transfer seat 6. The financial document transfer seat 6 then transfers the wrinkled financial documents along the financial document transfer guide rail 5 to the financial document storage platform 7, thereby achieving separate storage of wrinkled financial documents without secondary bending during storage, thus preventing the wrinkled financial documents from being damaged or clogging the financial document classification box due to stacking. At the same time, an image recognition module can be added. The LED light array in the image recognition module emits a single-sided light, creating a shadow on the backlit side of the wrinkles on the financial document. Grayscale processing and comparison of images of the financial documents captured under illumination are performed based on a grayscale threshold, automatically identifying wrinkled financial documents.

[0026] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
