[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0027] In the drawings, similar units are denoted by the same reference numerals.

[0028] Please refer to Figure 1 The present application discloses an intelligent certificate storage cabinet, which comprises a cabinet body 200 and a certificate issuing device 100 arranged on the cabinet body 200. The certificate issuing device 100 can store a plurality of stacked certificates 900 (see Figure 2 ) in batches and output the certificates 900 one by one. The user can put a plurality of certificates 900 into the certificate issuing device 100 at one time, and the certificate issuing device 100 outputs the certificates 900 one by one, which are sorted and conveyed to the corresponding storage positions by the related mechanisms in the intelligent certificate storage cabinet.

[0029] As Figure 2 , Figure 3 and​​​​​​Figure 4 As shown, the issuing device 100 includes an issuing box 1, a pushing mechanism 2, and an adaptive blocking mechanism 3. The issuing box 1 accommodates multiple stacked certificates 900, and has an outlet 11 on its bottom longitudinal Y side, from which the certificates 900 can be pushed out. The pushing mechanism 2 is located at the bottom of the issuing box 1 and is used to push the bottommost certificate 900 out of the outlet 11 along the longitudinal Y direction. The adaptive blocking mechanism 3 is located at the outlet 11 and is used to adjust the vertical dimension of the outlet 11 according to the thickness of the bottommost certificate 900, so that the outlet 11 and the certificate 900 match in the vertical Z direction, avoiding the simultaneous pushing out of two certificates 900.

[0030] like Figure 3 As shown, the adaptive document blocking mechanism 3 includes a detection component 31 and an adjustment component 32. The detection component 31 is used to detect the thickness of the bottommost document 900. The adjustment component 32 includes a document blocking frame 321 and an adjustment drive component 322. The document blocking frame 321 is movably disposed along the vertical Z direction at the upper edge of the document dispensing opening 11. The bottom edge position of the document blocking frame 321 can limit the height of the document dispensing opening 11, i.e., the vertical Z dimension, so that the document blocking frame 321 can block the second document 900 from the bottom to the top into the document box 1. The adjustment drive component 322 is connected to the document blocking frame 321 to drive the document blocking frame 321 to move along the vertical Z direction, thereby changing the vertical Z position of the document blocking frame 321. The adjustment drive component 322 is electrically connected to the detection component 31 to adjust the vertical Z position of the document blocking frame 321 according to the thickness of the bottommost document 900, thereby adjusting the vertical dimension of the document dispensing opening 11.

[0031] This invention uses the detection component 31 to detect the thickness of the bottommost document 900. The adjusting drive component 322 drives the book-blocking frame 321 to move vertically, thereby changing the vertical position of the book-blocking frame 321. The bottom edge of the book-blocking frame 321 can limit the vertical dimension of the document outlet 11, so that the vertical dimension of the document outlet 11 matches the thickness of the bottommost document 900. The book-blocking frame 321 can block the second document 900 from the bottom to the top into the book-issuing box 1, avoiding the issuance of multiple documents 900. This makes the issuing device 100 applicable to documents 900 of different thicknesses, making it convenient to use.

[0032] The document holder 1 is generally rectangular in shape to accommodate various square-shaped documents 900. The side of the document holder 1 opposite to the document dispensing opening 11 in the longitudinal Y direction is open, forming a document loading opening 12. This opening allows the user to easily load multiple documents 900 together into the document holder 1. A viewing window is also formed on the side of the document holder 1 opposite to the document dispensing opening 11 in the longitudinal Y direction. The viewing window is a strip-shaped structure extending from the top to the bottom of the document holder 1 in the vertical Z direction, allowing the user to observe the number of documents 900 inside. In the vertical Z direction, the bottom of the document loading opening 12 connects to the top of the viewing window. In the horizontal X direction, the width of the viewing window is smaller than the width of the document loading opening 12 to prevent documents 900 from falling out through the window. Of course, in other embodiments, the shape of the document holder 1 can be designed differently depending on the shape of the documents. The position of the document loading opening 12 can also be adjusted, such as at the top of the document holder 1. The window can be omitted.

[0033] like Figure 2 , Figure 3 As shown, in this embodiment, the detection component 31 includes a processing module (not shown) and a camera 311. The camera 311 is located on the bottom outer side of the document holder 1 to take a side view of the document 900. When the document 900 is a passport, the side view of the document 900 can be the spine of the passport, the two short sides adjacent to the spine, or the long side opposite to the spine. The processing module is electrically connected to the camera 311 to acquire the side view of the document 900 and analyze the thickness of the bottom layer of the document 900. The processing module is electrically connected to the adjustment drive 322 to control the movement of the adjustment drive 322, thereby causing the adjustment drive 322 to move the document holder 321 to a suitable position.

[0034] The side view photo of document 900 captured by camera 311 can show the difference between the connection position between two adjacent documents 900 and the middle position in the thickness direction of document 900. By performing image analysis processing on the side view photo of document 900 through the processing module, the connection position between two adjacent documents 900 can be determined, and the thickness of the bottom document 900 can be analyzed. When the bottom document 900 is a passport, if the side view of the document captured is the spine of the passport: the spine is convex, and in the captured image, the connection position between the adjacent passport and the document above is groove-like, so the image is darker, while the middle position in the thickness direction of the passport is convex, so the image is brighter. The connection position and the middle position are distinguished by the brightness of the image, thus determining the connection position. If the side view of the document captured is the two short sides adjacent to the spine or the long side opposite to the spine, then the connection position is the passport cover, and the middle position is the inner page. There is usually a color difference between the passport cover and the inner page, and the connection position and the middle position can be distinguished by the color difference.

[0035] Further, the detection assembly 31 further comprises a light supplement lamp 312, which is located at one side of the camera 311 and is arranged towards the side of the certificate 900. The light supplement lamp 312 can supplement the light of the shooting environment to avoid the poor light inside the smart certificate 900 storage cabinet, which affects the shooting clarity, so as to ensure the accuracy of the certificate 900 thickness identification.

[0036] In the embodiment, the camera is used for shooting and image analysis processing to detect the thickness of the bottom certificate. Here, the detection assembly is not limited to the above embodiment, and other detection methods can be used to obtain the thickness of the bottom certificate. For example, the passport in the certificate is taken as an example. The back of the certificate is a convex arc formed by folding, and the connection between the two certificates forms a groove. The position of the groove can be obtained by using a probe or infrared induction, so as to determine the thickness of the bottom certificate.

[0037] In the embodiment, the camera 311 and the certificate outlet 11 are arranged opposite to each other in the longitudinal direction Y to shoot the certificate 900 located at the certificate outlet 11. The certificate 900 at the certificate outlet 11 can more accurately reflect the thickness of the bottom certificate to be pushed out, so as to adjust the certificate blocking frame 321 to a more accurate position. Correspondingly, the light supplement lamp 312 is also arranged corresponding to the certificate outlet 11. The light supplement lamp 312 is preferably located at one side of the camera 311 in the transverse direction X. Of course, the light supplement lamp 312 can also be located at one side of the camera 311 in the vertical direction Z. The specific arrangement can be made according to the structure space inside the smart certificate 900 storage cabinet, which can make the camera 311 shoot a clearer side photo of the certificate 900. Here, as another embodiment, the camera 311 can also be arranged at the position of the certificate loading port 12 to shoot the side photo of the certificate 900 located at the certificate loading port 12, so as to shoot and analyze more certificates 900 at one time.

[0038] As shown in Figure 4 , Figure 5 , the certificate blocking frame 321 comprises a blocking block 3211. The blocking block 3211 is a strip arranged in the vertical direction Z and movably connected with the certificate issuing box 1 in the vertical direction Z. The bottom end of the blocking block 3211 is used to limit the vertical size of the certificate outlet 11. Through the movable cooperation of the blocking block 3211 and the certificate issuing box 1, the stability of the movement of the certificate blocking frame 321 in the vertical direction Z can be ensured. The blocking block 3211 is a strip arranged in the vertical direction Z, which has a simple structure and reduces the shielding area of the several certificates 900 at the certificate outlet 11, so as to facilitate the shooting of the camera 311.

[0039] The bottom end of the blocking block 3211 is provided with a roller 3212, and the rotation axis of the roller 3212 is in the transverse direction X, so as to facilitate the pushing out of the bottom certificate 900 from the certificate outlet 11 and avoid the abrasion of the surface of the certificate 900 caused by the blocking block 3211.
