Distributing the documents still requires significant manual intervention, resulting in low efficiency, relatively high error rates, high personnel costs, and a waste of time and effort. Furthermore, documents are divided into two types: primary documents (such as passports) and card-based documents (such as identity cards and Hong Kong and Macau passes). This increases the workload and makes centralized management difficult. Summary of the invention

[0003] The purpose of the present invention is to provide an intelligent evidence collection device to solve the technical problems in the prior art that a large amount of manual intervention is required when distributing certificates, resulting in low efficiency, high error rate and high personnel costs.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: providing an intelligent evidence collection device, which is communicatively connected to a background server, the intelligent evidence collection device including a mounting frame, the mounting frame having a loading area and a target area. The intelligent evidence collection device also includes an intelligent manipulator and an operating component for evidence collection personnel to perform evidence collection operations; the intelligent manipulator includes a main control unit and a transmission mechanism and a gripping device, both of which are controlled and connected to the main control unit, the transmission mechanism is provided on the mounting frame and connected to the gripping device, the transmission mechanism, the gripping device and the operating component are all controlled and connected to the main control unit, the main control unit is communicatively connected to the server, the transmission mechanism drives the gripping device to reciprocate between the loading area and the target area, and the main control unit controls the gripping and release of the gripping device.

[0005] The beneficial effect of the intelligent evidence collection device provided by the present invention is that the evidence collector uses the operating component to input information, the server obtains the information and the certificate information that matches the information, and transmits the target certificate to the loading area. Once in place, the main control unit controls the intelligent manipulator to grab the target certificate and transfer it to the target area, so that the evidence collector can take it away directly. If the certificate is not taken away within the preset time, the server sends a retention and removal signal to the main control unit, and the main control unit controls the functional grasping device to take away the certificate retained in the target area and return it to the loading area. On the one hand, it prevents others from taking it by mistake, and on the other hand, it facilitates subsequent normal operations.

[0024] Please also refer to Figure Figures 1 to 11 , the present invention provides an intelligent evidence collection device, which is communicatively connected to a background server. The intelligent evidence collection device 400 includes a mounting rack 100, and the mounting rack 100 has a loading area 101 and a target area 102. The intelligent evidence collection device 400 further includes an intelligent manipulator 200 and an operation component 410 for evidence collectors to perform evidence collection operations; the intelligent manipulator 200 includes a main control unit, a transfer mechanism 210 and a grasping device 220 that are both controlled and connected to the main control unit. The transfer mechanism 210 is disposed on the mounting rack 100 and is connected to the grasping device 220. The transfer mechanism 210, the grasping device 220 and the operation component 410 are all controlled and connected to the main control unit. The main control unit is communicatively connected to the server. The transfer mechanism 210 drives the grasping device 220 to reciprocate between the loading area 101 and the target area 102, and the main control unit controls the grasping device 220 to grasp and release.

[0025] In this embodiment, the forensic personnel input information using the operation component 410. The server obtains this information and the certificate information that matches it, and transfers the target certificate to the loading area 101. After it arrives, the main control unit controls the intelligent manipulator 200 to grab the target certificate and transfer it to the target area 102, where the forensic personnel can directly pick it up. If the certificate is not picked up beyond the preset time, the server sends a detention pick-up signal to the main control unit, and the main control unit controls the intelligent grasping device 220 to pick up the certificate detained in the target area 102 and put it back to the loading area 101. On the one hand, it prevents others from accidentally picking it up, and on the other hand, it facilitates subsequent normal operations. Through this intelligent forensic device 400, rapid forensics can be achieved without manual intervention, which is convenient and fast.

[0026] The operation component 410 includes a touch screen 411, which can provide forensic operation guidance for the forensic personnel and also allow the forensic personnel to input verification information, playing a role in human-computer interaction.

[0027] The operation component 410 also includes a camera 412, which is used to take pictures of the current forensic operator and store them in the server. It can also be used for face recognition verification. Additionally, it can perform live body identification, such as whether the operator is wearing a mask, etc., to prevent illegal operations.

[0028] The operation component 410 also includes a fingerprint scanner 413, which is used to obtain the fingerprints of the forensic personnel for identity verification.

[0029] The operation component 410 also includes a special code identifier 414. The forensic personnel can carry a forensic receipt with a special code for scanning and identification for forensics.

[0030] The operation component 410 also includes a printer (not shown in the figure), which is used to print a forensic receipt after forensics.

[0031] The touch screen 411, camera 412, fingerprint scanner 413, special code identifier 414, and printer are all connected to the main control unit for control.

[0032] The intelligent forensic device 400 includes a forensic housing 420, which wraps around the upper side and the peripheral side of the mounting frame 100, and a movable door can be arranged as needed. The touch screen 411, camera 412, fingerprint scanner 413, special code identifier 414, and printer are arranged on the same side of the forensic housing.

[0033] The loading area 101 is provided with a certificate inlet 106, and the target area 102 is provided with a forensics outlet. The forensics outlet includes a card-taking slot 107 and a book-taking port 108, which are used for the transmission of this type of certificate and card-type certificates. Of course, they can also share one outlet.

[0034] The intelligent evidence collection device 400 cooperates with the transfer robot. The transfer robot is communicatively connected to the server, and the server performs unified scheduling on it. The mounting frame 100 has a conveying space 109 below it for the transfer robot to move back and forth. The conveying space 109 is located below the loading area 101 and communicates with the certificate inlet 106. The transfer robot can accommodate multiple certificates (card - type certificates or / and book - type certificates). When the transfer robot moves to the conveying space 109, the loading device on it that holds the certificates is pushed to the opposite certificate inlet 106 for the intelligent manipulator 200 to grab; when it is necessary to take away the detained certificates, the intelligent manipulator 200 places the taken - down certificates on the loading device of the transfer robot, and uses the transfer robot to send them out. In this way, the evidence collection and detention management are realized in a fully intelligent and automated manner.

[0035] The mounting frame 100 is fixed with a guiding plate 430 at its bottom. The guiding plate 430 is provided with the certificate inlet 106. The certificate inlet 106 is downward and circumferentially provided with a guiding inclined surface, which can make the loading device of the transfer robot quickly insert into the certificate inlet 106 along the guiding inclined surface. Even if there is a small deviation in the alignment between the loading device and the certificate inlet 106, due to the positioning and guiding effect of the guiding inclined surface, a deviation - correcting effect can be achieved. Preferably, the shape of the certificate inlet 106 is adapted to the outer shape of the loading device.

[0036] Please refer to Figure 1 and Figure 2 and, an intelligent manipulator, which is used to transfer certificates. The certificates are divided into book - type certificates (such as passports, etc.) and card - type certificates (such as identity cards, Hong Kong and Macau passports, bank cards, etc.). The intelligent manipulator 200 given in this embodiment is not limited to being applied to certificate transfer, and can also be applied to other material transfers without limitation. The intelligent manipulator is assembled on the mounting frame 100 and reciprocates between the loading area 101 and the target area 102 of the mounting frame 100 to realize the automatic transfer of certificates. The target area 102 can be an area for storing certificates or an area for outputting certificates. The loading area 101 belongs to the certificate supply area. The intelligent manipulator 200 can transfer the certificates in the loading area 101 to the target area 102, and can also use the intelligent manipulator 200 to retrieve the certificates in the target area 102 and put them back into the loading area 101 to realize the fully automated operation of reciprocating transfer. The intelligent manipulator 200 includes a main control unit, a transfer mechanism 210 and a grasping device 220 that are all controlled and connected to the main control unit. The transfer mechanism 210 is arranged on the mounting frame 100 and is connected to the grasping device 220, and drives the grasping device 220 to reciprocally transfer certificates between the loading area 101 and the target area 102 under the control of the main control unit. The main control unit controls the grasping device 220 to grasp and release.

[0037] In this embodiment, the intelligent manipulator 200 includes a main control unit, a conveying mechanism 210 and a grasping device 220 controlled and allocated by the main control unit. Among them, the conveying mechanism 210 is installed on the mounting frame 100 and connected to the grasping device 220. The mounting frame 100 has a loading area 101 and a target area 102. Under the control of the main control unit, the conveying mechanism 210 drives the grasping device 220 to reciprocate between the loading area 101 and the target area 102 of the mounting frame 100 to realize automatic storage and retrieval of documents. The grasping device 220 can grasp and release documents under the control of the main control unit. In this way, the intelligent manipulator 200 can be used to convey the documents in the loading area 101 to the target area 102 one by one, or the intelligent manipulator 200 can be used to take out the documents in the target area 102 and convey them to the loading area 101, realizing the full intelligence and automation of document management. The intelligent manipulator 200 can completely replace manual operation, eliminating the cumbersome operations of manually conveying documents and searching for target documents, achieving the effects of fast conveying, accurate storage and retrieval of documents, saving time and effort, greatly reducing the cost investment, and truly achieving the intelligent and automated effects of the product.

[0038] Please also refer to Figures 1 to 3 , the conveying mechanism 210 includes a first horizontal conveying device 211, a vertical conveying device 212 and a second horizontal conveying device 213, all of which are connected to the main control unit for control.

[0039] The first horizontal conveying device 211 is arranged on the mounting frame 100 and connected to the vertical conveying device 212, and it drives the vertical conveying device 212 to reciprocate in the horizontal plane along the first horizontal direction.

[0040] The vertical conveying device 212 is connected to the second horizontal conveying device 213, and it drives the second horizontal conveying device 213 to reciprocate in the vertical direction.

[0041] The second horizontal conveying device 213 is connected to the grasping device 220, and it drives the grasping device 220 to reciprocate in the horizontal plane along the second horizontal direction. There is an included angle θ between the second horizontal direction and the first horizontal direction, and 0° < θ < 180°.

[0042] In this embodiment, by using the first horizontal conveying device 211, the vertical conveying device 212 and the second horizontal conveying device 213 of the conveying mechanism 210, the grasping device 220 can be driven to move along the first horizontal direction, the second horizontal direction and the vertical direction. Generally, the included angle θ between the first horizontal direction and the second horizontal direction is taken as 90°, that is, the grasping device 220 can be freely displaced and conveyed in the three-dimensional space of the X-axis (the first horizontal direction), the Y-axis (the second horizontal direction) and the Z-axis (the vertical direction), improving the spatial range and flexibility of document conveying, as Figure 1 , Figure 2 shown.

[0043] The first horizontal conveyor 211 includes a first driving assembly 2111, a first sliding connection assembly 2112, and a first support frame 2113. The first sliding connection assembly 2112 is connected between the mounting frame 100 and the first support frame 2113, and the sliding direction of the first support frame 2113 relative to the mounting frame 100 is the first horizontal direction. Under the control of the main control unit, the first driving assembly 2111 drives the first support frame 2113 to reciprocate along the first horizontal direction, and the vertical conveyor 212 is fixedly connected to the first support frame 2113. In this way, while the first driving assembly 2111 drives the first support frame 211 to reciprocate along the first horizontal direction, it drives the vertical conveyor 212 fixed on the first support frame 2113 to reciprocate along the first horizontal direction. The grasping device 220 is indirectly connected to the first support frame 2113 through the vertical conveyor 212 and the second horizontal conveyor 213. The vertical conveyor 212 is connected to the second horizontal conveyor 213. Therefore, the grasping device 220 is driven to move along the first horizontal direction.

[0044] The first driving assembly 2111 includes a first power source 21111, a first gear 21112, and a first rack 21113. The first power source 21111 is fixed to the first support frame 2113, and its power output shaft is connected to the first gear 21112. The power output shaft can drive the first gear 21112 to rotate synchronously forward and backward. The first rack 21113 is fixed to the mounting frame 100 and meshes with the first gear 21112. In this way, the forward and reverse meshing movement of the first gear 21112 and the first rack 21113 is transformed into the forward and reverse movement of the first support frame 2113 relative to the first rack 21113. The extending direction of the first rack 21113 is the first horizontal direction. In this embodiment, the first power source 21111 is a driving motor. The main control unit controls the starting time, forward rotation, or reverse rotation of the driving motor according to the acquired signal.

[0045] The first gear 21112 and the first rack 21113 can be in straight-tooth meshing or helical-tooth meshing.

[0046] To achieve stable movement and precise directional transmission effects, the cooperation mode of the slide rail 10 and the slider 20 is usually adopted. Generally, there are two structural schemes. Scheme one: the slide rail 10 is long and the slider 20 is short. The extension direction of the slide rail 10 is consistent with the predetermined transmission direction. The slider 20 is slidably connected to the slide rail 10 and slides directionally along the extension direction of the slide rail 10. Scheme two: the slide rail 10 is short and the slider 20 is long. The extension direction of the slider 20 is consistent with the predetermined transmission direction. The slide rail 10 is slidably connected to the slider 20 and slides directionally along the extension direction of the slider 20. The sliding connection structure of the slide rail 10 and the slider 20 usually includes a sliding groove 11 and a sliding protrusion 21. The sliding protrusion 21 is inserted into the sliding groove 11 and the two can slide relative to each other. The two can be respectively arranged on the slide rail 10 and the slider 20 to realize the sliding connection relationship between the slide rail 10 and the slider 21, as specifically shown in Figure 3 shown.

[0047] Please refer to Figures 1 to 3 simultaneously. The first sliding connection component 2112 includes at least one first slide rail 21121 and at least one first slider 21122. The specific structural scheme can be scheme one or scheme two in the above-mentioned structural scheme of the slide rail 10 and the slider 20. The long part (the slide rail 10 in scheme one or the slider 20 in scheme two) is fixed on the mounting rack 100, and the short part (the slider 20 in scheme one or the slide rail 10 in scheme two) is fixed on the first support frame 2113. The short part slides along the extension direction of the long part, and the extension direction of the long part is the same as the extension direction of the first rack 21113. In this way, by connecting the first support frame 2113 and the mounting rack 100 through the first sliding connection component 2112, on the one hand, the stable support of the first support frame 2113 is realized, and on the other hand, the first support frame 2113 is realized to move reciprocally in a fixed direction along the first horizontal direction, and the smoothness of its movement is improved, that is, the smoothness of the reciprocating movement of the grasping device 220 along the first horizontal direction is improved.

[0048] In this embodiment, the first sliding connection component 2112 adopts the above-mentioned scheme one. The length direction of each first slide rail 21121 and the length direction of the first rack 21113 are both the same as the first horizontal direction.

[0049] Preferably, at least one first slider 21122 slidably connected to each first slide rail 21121 can be provided, which can be determined according to specific requirements.

[0050] Preferably, two first sliding connection components 2112 are provided and the sliding directions are the same. The two are parallel to each other and arranged at intervals, and both are connected to the first support frame 2113 and the mounting rack 100, which can further improve the smoothness of the movement of the grasping device 220 along the first horizontal direction. Preferably, the first driving component 2111 is located between the two first sliding connection components 2112.

[0051] Please refer to Figures 1 to 3, in order to better improve the smoothness of the transmission of the grasping device 220 in the first horizontal direction, the first horizontal conveying device 211 further includes a second driving component 2114, a second sliding connection component 2115 and a second support frame 2116. The second sliding connection component 2115 is connected between the mounting frame 100 and the second support frame 2116, and the sliding direction of the second support frame 2116 relative to the mounting frame 100 is the first horizontal direction. Under the control of the main control unit, the second driving component 2114 drives the second support frame 2116 to reciprocate synchronously with the first support frame 2113 along the first horizontal direction, and the vertical conveying device 212 is fixedly connected to the second support frame 2116. In this way, the first driving component 2111 and the second driving component 2114 are started simultaneously, and drive the first support frame 2113 and the second support frame 2116 to reciprocate synchronously along the first horizontal direction, and at the same time drive the vertical conveying device 212 to reciprocate along the first horizontal direction, better improving the smoothness and stability of the sliding along the first horizontal direction, avoiding the start of one end and the lag of the other end resulting in deviation, causing unstable transmission and reduced accuracy, and at the same time reducing the overall service life. In addition, it effectively expands the transmission stroke of the grasping device 220 in the vertical direction to meet the use requirements. The two ends of the vertical conveying device 212 are respectively fixed to the first support frame 2113 and the second support frame 2116.

[0052] The mounting frame 100 includes an upper cross beam 110 and a lower cross beam 120, and the upper cross beam 110 and the lower cross beam 120 are parallel to each other and arranged at intervals. The first sliding connection component 2112 connects the lower cross beam 120 and the first support frame 2113, the second sliding connection component 2115 connects the upper cross beam 110 and the second support frame 2116, and the two ends of the vertical conveying device 212 are respectively fixed to the first support frame 2113 and the second support frame 2116. The distance between the upper and lower cross beams (110, 120) is determined by the vertical stroke of the grasping device 220.

[0053] The second driving component 2114 includes a second power source 21141, a second gear 21142, and a second rack (not shown in the figure). The second power source 21141 is fixed to the second support frame 2116, and its power output shaft is connected to the second gear 21142. The power output shaft can drive the second gear 21142 to rotate synchronously forward and backward. The second rack is fixed to the mounting frame 100 and meshes with the second gear 21142. In this way, the forward and reverse meshing movement between the second gear 21142 and the second rack is converted into the forward and reverse movement of the first support frame 2113 relative to the second rack. The extending direction of the second rack is the first horizontal direction. In this embodiment, the second power source 21141 is a driving motor. The main control unit controls the synchronous starting timing, synchronous forward rotation, or reverse rotation of the first power source 21111 and the second power source 21141 according to the acquired signals, so that the moving directions and speeds of the first support frame 2113 and the second support frame 2116 are the same, achieving a synchronous effect.

[0054] The second gear 21142 and the second rack can be in straight-tooth meshing or helical-tooth meshing.

[0055] Please also refer to Figures 1 to 3 , the second sliding connection component 2115 includes at least one second slide rail (not shown in the figure) and at least one second slider 21151. The specific structural solution can be Solution 1 or Solution 2 in the above structural solution of the slide rail 10 and the slider 20. The long part (the slide rail 10 in Solution 1 or the slider 20 in Solution 2) is fixed to the mounting frame 100, and the short part (the slider 20 in Solution 1 or the slide rail 10 in Solution 2) is fixed to the second support frame 2116. The short part slides along the extending direction of the long part, and the extending direction of the long part is the same as the extending direction of the second rack. In this way, by connecting the second support frame 2116 and the mounting frame 100 through the second sliding connection component 2115, on the one hand, the stable support of the second support frame 2116 is realized, and on the other hand, the second support frame 2116 is realized to move reciprocally in a fixed direction along the first horizontal direction, and the smoothness of its movement is improved, that is, the smoothness of the reciprocating movement of the grasping device 220 along the first horizontal direction is better improved.

[0056] Preferably, two second sliding connection components 2115 are provided and have the same sliding direction. The two are parallel to each other and arranged at intervals, and both are connected to the second support frame 2116 and the mounting frame 100, which can better improve the smoothness of the movement of the grasping device 220 along the first horizontal direction. Preferably, the second driving component 2114 is located between the two second sliding connection components 2115.

[0057] As an alternative to the first drive assembly 2111 and / or the second drive assembly 2114, a lead screw and nut combination can be used to drive the support frame. Specifically, it includes a lead screw, a power source, and a nut. The power output shaft of the power source is docked with one end of the lead screw to drive the lead screw to rotate. The nut is sleeved on the lead screw and threadedly connected to the lead screw. At the same time, circumferential limitation is imposed on the nut. When the lead screw rotates, the nut does not rotate with the rotation of the lead screw but moves along with the rotation of the lead screw. The moving direction is the extending direction of the lead screw. The first and second support frames can be fixedly connected to the nut, and the vertical transfer device 212 is fixed on the upper side of the support frame to realize reciprocating movement along the first horizontal direction with the vertical transfer device 212. The first horizontal direction is the same as the length direction of the lead screw.

[0058] Please also refer to Figures 2 to 4 , the vertical transfer device 212 includes a vertical drive assembly 2121, a vertical fixing frame 2122, and a vertical support frame 2123. The two ends of the vertical fixing frame 2122 are respectively fixedly connected to the first support frame 2113 and the second support frame 2116; under the control of the main control unit, the vertical drive assembly 2121 drives the vertical support frame 2123 to reciprocally slide along the vertical direction relative to the vertical fixing frame 2122. The second horizontal transfer device 213 is fixedly connected to the vertical support frame 2123, that is, indirectly drives the grasping device 220 to shift along the vertical direction.

[0059] In this embodiment, the vertical drive assembly 2121 is a linear motor, that is, the vertical drive assembly 2121 includes a primary winding and a secondary winding. Its working principle is as follows: when an alternating current power supply is applied to the primary winding, a traveling wave magnetic field is generated in the air gap. When the secondary winding is cut by the traveling wave magnetic field, an electromotive force will be induced and a current will be generated. The interaction between this current and the magnetic field in the air gap generates an electromagnetic thrust, that is, electrical energy is converted into mechanical energy of linear motion. If the primary (stator 21211) is fixed, the secondary (rotor 21212) will move linearly under the action of the thrust; conversely, the primary will move linearly. In this embodiment, the former is selected. The stator 21211 is fixed on the vertical fixing frame 2122, and the rotor 21212 is fixed on the vertical support frame 2123. After being energized, the rotor 21212 is driven by the thrust to drive the vertical support frame 2123 to slide along the vertical direction relative to the vertical fixing frame 2122.

[0060] As an alternative, the vertical drive assembly 2121 can use a lead screw and nut combination, specifically as the alternative of the above-mentioned first and second drive assemblies (2111, 2114), which will not be elaborated here.

[0061] Please also refer to Figures 2 to 4, preferably, the vertical conveying device 212 further includes a vertical sliding connection assembly 2124. The vertical sliding connection assembly 2124 connects the vertical fixing frame 2122 and the vertical support frame 2123, and is used to enable the vertical support frame 2123 to slide relative to the vertical fixing frame 2122, and the sliding direction is the vertical direction, that is, the vertical support frame 2123 and the vertical fixing frame 2122 are slidably connected through the vertical sliding connection assembly 2124. In this way, on the one hand, directional sliding is achieved, on the other hand, the vertical support frame 2123 can be displaced more stably, and furthermore, it has the effect of connecting the vertical support frame 2123 and the vertical fixing frame 2122.

[0062] The vertical fixing frame 2122 includes a vertical frame body 21221 with both ends respectively fixed on the first support frame 2113 and the second support frame 2116, and the stator 21211 is fixed to the vertical frame body 21221. The vertical sliding connection assembly 2124 includes a vertical slide rail 21241 and a vertical slider 21242, and at least one of each is provided. The specific structural solution can be the first or second solution in the above-mentioned slide rail 10 and slider 20 structural solutions. Taking the first solution as an example, the vertical slide rail 21241 is fixed to the vertical frame body 21221, the vertical slider 21242 is fixed to the vertical support frame 2123, and the vertical slider 21242 is slidably connected with the vertical slide rail 21241 and the sliding direction is the vertical direction. In this way, under the drive of the vertical drive assembly 2121, the vertical support frame 2123 and the vertical fixing frame 2122 are slidably connected through the vertical sliding connection assembly 2124, and the reciprocating sliding of the grasping device 220 in a stable and directional (vertical direction) manner is better realized.

[0063] Specifically, the vertical frame body 21221 has a vertically penetrating U-shaped groove 201, and the stator 21211 is fixed to the bottom of the U-shaped groove 201, which plays a role in protecting the stator 21211.

[0064] Preferably, two vertical slide rails 21241 are provided and are respectively fixed to both end faces of the vertical frame body 21221 located at its transverse notch. The extending direction of each vertical slide rail 21241 is the same as the extending direction of the vertical frame body 21221, and both are in the vertical direction. At least one vertical slider 21242 slidably connected with each vertical slide rail 21241 is provided, and all are fixedly connected to the vertical support frame 2123. The mover 21212 is fixed between the two rows of vertical slide rails 21241 and is opposite to the stator 21211. In this way, the stability of the support and sliding of the vertical support frame 2123 is better improved, and at the same time, it also plays a role in protecting the vertical drive assembly 2121.

[0065] As an alternative to the sliding connection between the vertical fixing frame 2122 and the vertical support frame 2123, the vertical sliding component 2124 may not be added, and the vertical support frame 2123 and the vertical fixing frame 2122 can be directly used for sliding connection. The specific sliding structure can refer to the sliding structure of the slide rail 10 and the slider 20 described above.

[0066] Please refer to Figure 4 , the vertical transmission device 212 further includes a position detection component 2125. The position detection component 2125 includes a lower detection piece 21251 for detecting the lower extreme position where the vertical support frame 2123 slides to the vertical fixing frame 2122 and an upper detection piece 21252 for detecting the upper extreme position where the vertical support frame 2123 slides to the vertical fixing frame 2122. The lower detection piece 21251 is fixed to the lower extreme position of the vertical fixing frame 2122, and the upper detection piece 21252 is fixed to the upper extreme position of the vertical fixing frame 2122. The distance between the upper extreme position and the lower extreme position of the vertical fixing frame 2122 is the maximum stroke of the vertical support frame 2123 sliding in the vertical direction, that is, the sliding stroke of the grasping device 220 in the vertical direction. When it is detected that the vertical support frame 2123 slides to the upper extreme position or the lower extreme position, the main control unit controls the vertical support frame 2123 to stop. In this embodiment, the upper and lower detection pieces are position sensors. The position detection component 2125 further includes a positioning piece 21253 fixed to the vertical support frame 2123, and the positioning piece 21253 is fixed on one side of the vertical support frame 2123. When the vertical support frame 2123 slides to the upper extreme position under the drive of the vertical drive component 2121, the upper detection piece 21252 located at the upper extreme position senses the positioning piece 21253, and then controls the vertical drive component 2121 to stop driving; similarly, when sliding to the lower extreme position, it will also be detected and stop sliding. In this way, on the one hand, the vertical stroke can be determined; on the other hand, the safety of vertical sliding can be better protected.

[0067] Please refer to Figure 4 , the vertical support frame 2123 is provided with an upper buffer 2126 and a lower buffer 2127. At least one upper buffer 2126 is provided and is fixed to the upper side surface of the vertical support frame 2123, and at least one lower buffer 2127 is also provided and is fixed to the lower side surface of the vertical support frame 2123. The upper and lower buffers (2126, 2127) have certain buffering performance. When the vertical support frame 2123 slides to the upper extreme position and the lower extreme position of the vertical fixing frame 2122, the upper buffer 2126 and the lower buffer 2127 can directly abut against the extreme ends of the vertical fixing frame 2122 or the first support frame 2113 and the second support frame 2116, avoiding direct contact of rigid parts, causing damage to rigid parts, shortening the service life, generating collision noises, etc. Therefore, it plays a role in protecting the vertical support frame 2123 and the vertical fixing frame 2122.

[0068] The upper and lower buffer members (2126, 2127) can use components with a buffering effect such as rubber materials and silicone materials, and buffer members made of different materials can be selected for the upper and lower parts according to the different magnitudes of the applied forces.

[0069] Please refer to Figure 4 , the vertical fixing frame 2122 further includes side wing plates 21222 respectively extending and formed from both end faces at the transverse notch in the vertical frame body 21221. Each side wing plate 21222 extends along the length direction of the vertical frame body 21221, and the vertical sliding connection assembly 2124 is located between the two side wing plates 21222. In this way, through the two side wing plates 21222, the components between the two side wing plates 21222 can be protected, preventing dust, metal parts, etc. from entering and affecting the normal operation of the vertical conveying device 212. Preferably, both ends of each side wing plate 21222 respectively extend to the first support frame 2113 and the second support frame 2116 and are fixedly connected.

[0070] Please refer to Figure 4 , the vertical fixing frame 2122 further includes a dust-proof cloth 21223. One end of the dust-proof cloth 21223 is fixed to the first support frame 2113, and the other end is fixed to the second support frame 2116. The dust-proof cloth 21223 is stretched between the first support frame 2113 and the second support frame 2116, and the width of the dust-proof cloth 21223 is greater than or equal to the distance between the two side wing plates 21222. The vertical support frame 2123 slides inside the dust-proof cloth 21223. In this way, the components located inside the vertical fixing frame 2122 can be better protected, and it is better to prevent dust, metal parts and other components from entering and affecting the normal operation of the vertical conveying device 212. Especially, the vertical driving assembly 2121 uses a linear motor, and the stator 21211 is fixed to the bottom of the slot of the vertical frame body 21221 and has a certain magnetic attraction force, which needs to be protected emphatically.

[0071] Please refer to Figure 4 , preferably, the vertical support frame 2123 has a vertically penetrating accommodation groove 202, and the accommodation groove 202 faces away from the vertical driving assembly 2121 for the dust-proof cloth 21223 to pass through the accommodation groove 202 to prepare for subsequent fixed connection with the second horizontal conveying device 213.

[0072] Please refer to simultaneously Figures 4 to 6, the vertical conveyor 212 further includes a power-off protection structure 2128. The power-off protection structure 2128 includes a lock head 21281, an elastic member 21282, a transmission assembly 21283, a driving member 21284, and a mounting shell 21285 fixed to the vertical support frame 2123. The mounting shell 21285 is provided with a through hole 203 on the side wall facing the vertical fixing frame 2122. The transmission assembly 21283 is disposed inside the mounting shell 21285 and is electrically connected to the driving member 21284. The transmission end of the transmission assembly 21283 passes through the through hole 203 and is connected to the lock head 21281. The elastic member 21282 is disposed on the transmission end of the transmission assembly 21283 and is compressed between the lock head 21281 and the mounting shell 21285.

[0073] On the surface of the vertical fixing frame 2122 facing the lock head 21281, a plurality of locking positions 204 are arranged at intervals in the vertical direction, so as to prevent the vertical driving assembly 2121 from having a corresponding locking position 204 when power is cut off at any position, thereby playing a role in power-off protection.

[0074] The end of the lock head 21281 facing the locking position 204 is provided with a locking inclined surface 205. The locking inclined surface 205 is used for quick guiding when connecting with the locking position 204, so as to improve the locking efficiency. The locking inclined surface 205 is an inclined cutting surface or a conical surface. In this embodiment, an inclined cutting surface is selected, such as Figure 5 and Figure 6 shown.

[0075] When the driving member 21284 is energized, it pulls the transmission assembly 21283 to shift, causing the lock head 21281 to move towards the mounting shell 21285 and compress the elastic member 21282. At this time, a safe distance is maintained between the lock head 21281 and each locking position 204, enabling the vertical support frame 2123 to reciprocate vertically under the drive of the vertical drive assembly 2121, and the lock head 21281 will not touch any components; when the driving member 21284 is de-energized, under the elastic restoring force of the elastic member 21282, the lock head 21281 is quickly pushed towards the locking position 204 opposite when de-energized, and is locked and cooperated with the locking position 204. The power supply of the driving member 21284 is the same as that of the vertical drive assembly 2121. It can be understood that when the driving member 21284 is energized, the driving member 21284 drives the transmission assembly 21283 to pull the lock head 21281, and the lock head 21281 moves towards the mounting shell 21285. At the same time, the lock head 21281 and the mounting shell 21285 jointly compress the elastic member 21282. At this time, there is a certain distance between the lock head 21281 and each locking position 204, ensuring that the vertical support frame 2123 can smoothly reciprocate vertically under the drive of the vertical drive assembly 2121. When the driving member is de-energized, due to the elastic member 21282 having a certain elastic restoring force, and the driving member 21284 causes the pulling force applied by the transmission assembly 21283 to the lock head 21281 to disappear due to power-off. In this way, the lock head 21281 is quickly ejected under the elastic restoring force of the elastic member 21282 and is locked with the locking position 204 when de-energized, fixing the vertical support frame 2123 to prevent rapid drop or free fall due to power-off and damage to the vertical transmission device 212.

[0076] The driving member 21284 is a stepper motor, that is, an open-loop control motor that converts an electrical pulse signal into an angular displacement. It can be understood that when the driving member 21284 is energized, its output shaft rotates a certain angular displacement, and the transmission assembly 21283 connected to the output shaft undergoes a linear displacement and pulls the lock head 21281 to move together; when the driving member 21284 is de-energized, the power source of the output shaft disappears, and under the elastic restoring force of the elastic member 21282, the lock head 21281 is instantly ejected and locked with the corresponding locking position 204 when de-energized, and the output shaft also rotates reversely to the initial position under the action of the elastic restoring force, achieving a reset effect.

[0077] In this embodiment, the elastic member 21282 is a spring, which can be a cylindrical helical spring or a conical helical spring, and is selected according to needs.

[0078] Please refer to Figure 4 and Figure 5, the transmission assembly 21283 includes a push rod 21286 and a transmission member 21287 threadedly connected to the output shaft of the driving member 21284. One end of the push rod 21286 is fixedly connected to the transmission member 21287, and the other end thereof extends out through the through hole 203 and is fixedly connected to the lock head 21281. The elastic member 21282 is sleeved on the extending end of the push rod 21286, and the transmission member 21287 is circumferentially limited within the mounting shell 21285.

[0079] In this embodiment, the central line of the push rod 21286 is the same as the axis of the output shaft of the driving member 21284.

[0080] In this embodiment, the transmission member 21287 has an open cavity 206. The output shaft of the driving member 21284 is inserted into the open cavity 206 from the cavity opening and is threadedly connected to the cavity opening. At the same time, the outer contour of the cross section of the transmission member 21287 is non-circular and is adapted to the inner wall of the mounting shell 21285 to achieve circumferential limitation of the transmission member 21287. When the power output shaft has an angular displacement, the transmission member 21287 is displaced along the axis direction of the power output shaft to achieve the purpose of pulling the push rod 21286.

[0081] Please also refer to Figures 4 to 6 , as an alternative, the transmission assembly 21283 includes a push rod 21286 and a transmission member 21287 that moves synchronously with the output shaft of the driving member 21284. One end of the push rod 21286 is hinged to the transmission member 21287, and there is a certain distance between the hinge position and the axis. The other end of the push rod 21286 extends out through the through hole 203 and is fixedly connected to the lock head 21281. The elastic member 21282 is sleeved on the extending end of the push rod 21286. Specifically, the transmission member 21287 is a runner that undergoes an angular displacement together with the power output shaft. The runner can be a cam or other conventional components. One end of the push rod 21286 is hinged to the rotating member 21287 and has a certain distance from the rotation axis of the transmission member 21287. This distance is the rotation radius. When the power output shaft has an angular displacement, the transmission member 21287 also undergoes an angular displacement synchronously, pulling the push rod 21286 that has a certain distance from the rotation axis to achieve the purpose of pulling the push rod 21286.

[0082] Please also refer to Figure 2 、 Figure 4 、 Figure 7 and Figure 8, the second horizontal conveyor 213 includes a third driving assembly 2131, a third sliding assembly 2132, and a third support frame 2133. The third sliding assembly 2132 is connected between the vertical support frame 2123 and the third support frame 2133 to enable the third support frame 2133 to slide relative to the vertical support frame 2123, and the sliding direction is the second horizontal direction. Under the control of the main control unit, the third driving assembly 2131 drives the third support frame 2133 to reciprocate along the second horizontal direction. The gripping device 220 is connected to the third support frame 2133 and reciprocates along the second horizontal direction together with the third support frame 2133, increasing the movement freedom of the gripping device 220. The second horizontal direction forms an angle θ with the first horizontal direction, and 0° < θ < 180°. Generally, θ is taken as 90°.

[0083] The second horizontal conveyor 213 further includes a third fixing frame 2134, and one end of the third fixing frame 2134 is fixed to the vertical support frame 2123. Specifically, the third fixing frame 2134 is fixed on the side of the vertical support frame 2123 opposite to the vertical driving assembly 2121, and together with the receiving groove 202 of the vertical support frame 2123, it forms a receiving cavity for the dust-proof cloth 21223 to pass through.

[0084] Please refer to Figure 7 and Figure 8 , the third driving assembly 2131 includes a third power source 21311, a third gear 21312, and a third rack 21313. The third power source 21311 is fixed to the other end of the third fixing frame 2134. The third gear 21312 is located between the third fixing frame 2134 and the third support frame 2133 and is connected to the power output shaft of the third power source 21311. The power output shaft can drive the third gear 21312 to rotate synchronously forward and backward. The third rack 21313 is fixed to the third support frame 2133 and meshes with the third gear 21312. In this way, the forward and reverse meshing movement of the third gear 21312 and the third rack 21313 is converted into the reciprocating movement of the third support frame 2133 relative to the third fixing frame 2134. The extending direction of the third rack 21313 is the second horizontal direction. In this embodiment, the third power source 21311 is a driving motor. The main control unit controls the starting time, forward rotation or reverse rotation of the driving motor according to the acquired signal. The third rack 21313 can be integrally formed with the third support frame 2133.

[0085] In this embodiment, the third support frame 2133 is provided with a strip-shaped window 207. The length direction of the strip-shaped window 207 is the second horizontal direction. The tooth-shaped part of the third rack 21313 and the third gear 21312 are both exposed through the strip-shaped window 207. This is because the third fixing frame 2134 faces the third support frame 2133. The third power source 21311 is fixed on the side of the third fixing frame 2134 opposite to the third support frame 2133, and it is on the same side as the vertical support frame 2123. The end of the power output shaft of the third power source 21311 extends horizontally between the third fixing frame 2134 and the third support frame 2133. The tooth-shaped part of the third rack 21313 faces upward or downward. By providing the strip-shaped window 207, on the one hand, it is convenient to observe whether the third gear 21312 and the third rack 21313 are assembled in place and facilitate adjustment; on the other hand, it avoids the third gear 21312 and prevents the third gear 21312 from interfering with the position of the third support frame 2133 during movement, reducing the service life of the components. The length of the strip-shaped window 207 can be the maximum stroke of the grasping device 220 sliding along the second horizontal direction. If the strip-shaped window 207 is too long, multiple reinforcing ribs can be added in the middle. In addition, the overall assembly structure between the third driving assembly 2131 and the third fixing frame 2134 and the third support frame 2133 is compact, reducing the space occupancy rate.

[0086] The third gear 21312 and the third rack 21313 can be in straight-tooth meshing or helical-tooth meshing.

[0087] Please also participate Figure 3 and Figure 7 Moreover, the third sliding connection assembly 2132 includes at least one third slide rail 21321 and at least one third slider 21322. The specific structural solution can be the first or second solution in the above-mentioned structural solution of the slide rail 10 and the slider 20. Taking the first solution as an example, the third slide rail 21321 is fixed on the third support frame 2133, and the third slider 21322 is fixed on the third fixing frame 2134. The third slider 21322 is slidably connected to the third slide rail 21321 and the sliding direction is the second horizontal direction. In this way, driven by the third driving assembly 2131, the third support frame 2133 and the third fixing frame 2134 are slidably connected through the third sliding connection assembly 2132, better realizing the stable and directional (second horizontal direction) reciprocating sliding of the grasping device 220.

[0088] Preferably, two third sliding connection assemblies 2132 are provided and have the same sliding direction. The two are parallel to each other and arranged at intervals, and both connect the third support frame 2133 and the third fixing frame 2134, which can better improve the smoothness of the grasping device 220 moving along the second horizontal direction. Preferably, the third driving assembly 2131 is located between the two third sliding connection assemblies 2132.

[0089] Please refer toFigure 7 Moreover, the second horizontal transfer device 213 further includes a limit position detection member 2135. The limit position detection member 2135 is fixed to the third support frame 2133 or the third fixing frame 2134 and is used to detect the limit position when the third support frame 2133 is retracted, which can also be regarded as the zero position.

[0090] The limit position detection member 2135 is fixed at the transfer end of the third support frame 2133, and the detection end faces the end of the third fixing frame 2134. Of course, an additional induction member can also be provided and fixed to the third fixing frame 2134. When the limit position detection member 2135 approaches the target object (the end of the third fixing frame 2134 or the additional induction member) during the return stroke of the third support frame 2133, it indicates that the third support frame 2133 has returned to the limit position or the zero position, and the main control unit controls the third power source 21311 to stop power output, playing a protective role.

[0091] Please refer to Figure 2 、 Figure 4 、 Figure 7 and Figure 8 As shown in, the transfer mechanism 210 includes a rotary transfer assembly 214. The rotary transfer assembly 214 is fixed to the second horizontal transfer device 213 and, under the control of the main control unit, drives the gripping device 220 to rotate around the power output axis of the rotary transfer assembly 214. The second horizontal transfer device 213 drives the rotary transfer assembly 214 and the gripping device 220 to reciprocate in the second horizontal direction. Combining the foregoing content, by using the transfer mechanism 210 to drive the gripping device 220, the gripping device 220 can be transferred in the first horizontal direction, the second horizontal direction, the vertical direction, and the rotational direction, achieving four degrees of freedom, and better improving the spatiality and flexibility of its transfer.

[0092] In this embodiment, the main control unit controls the rotary transfer assembly 214 to drive the gripping device 220 to reciprocally rotate between the loading area 101 and the target area 102, improving the flexibility of the gripping device 220 to transfer documents. The rotation angle generally ranges from 0° to 180°. Of course, the rotation angle range can also be expanded as needed.

[0093] Please refer to Figure 7 and Figure 8 As shown in, the rotary transfer assembly 214 includes a rotary drive source 2141. The rotary drive source 2141 is fixed to the transfer end of the third support frame 2133. The power output shaft of the rotary drive source 2141 is connected to the gripping device 220 and drives the gripping device 220 to rotate synchronously.

[0094] The rotating conveyor assembly 214 further includes a speed reducer 2142. The power output shaft of the rotating drive source 2141 is connected to the power input end of the speed reducer 2142, and the grasping device 220 is connected to the power output end of the speed reducer 2142. By providing the speed reducer 2142, the rotation speed output by the rotating drive source 2141 can be effectively regulated, so that the transmission of the grasping device 220 is more stable. In this embodiment, the rotating drive source 2141 is a drive motor, and the speed reducer 2142 is a harmonic speed reducer 2142.

[0095] The rotating conveyor assembly 214 further includes a first roller 2143, a second roller 2144 and a conveyor belt 2145. The first roller 2143 is sleeved on the power output shaft of the rotating drive source 2141 and rotates synchronously with the power output shaft. The second roller 2144 is connected to the power input end of the speed reducer 2142, and the speed reducer 2142 is also fixed to the conveying end of the third support frame 2133. The first roller 2143 and the second roller 2144 are located on the same side of the third support frame 2133, and the conveyor belt 2145 is sleeved on both of them for power transmission.

When taking evidence, the specific location of the target document can be known immediately. When taking out the document, the document information is read to verify whether the document is the target document. When the intelligent manipulator 200 is applied to an evidence-taking device, the reading unit 224 is used to obtain the document information to verify whether it is the target document. When the document in the target area 102 exceeds the preset collection time, the document is grasped and the information is obtained, and the server automatically records the delay in collection. In this embodiment, the first corner limit detection member 21451 is used to detect the position of the grasping end of the grasping device 220 vertically upward, and the second limit detection member 21452 is used to detect the position of the grasping end of the grasping device 220 vertically downward.

[0108] The reading unit 224 is an RFID module 2241 and / or an OCR module 2242.

The document information includes document numbers, types, identity information of the personnel to whom the document belongs, etc., and is not limited thereto.

[0109] Please refer to Figure 7 and Figure 8 , the grasping device 220 further includes a grasping detection unit 225 for detecting whether there is a document on the grasping assembly 222 and for detecting whether the document is inserted into a specified position of the grasping assembly 222 when grasping the document. The grasping detection unit 225 is provided on the grasping support frame 223. In this way, on the one hand, it is convenient to control the position of the document to ensure that the document is clamped properly; on the other hand, it prevents scratching other components during transmission and affects normal transmission.

[0110] In this embodiment, the grasping detection unit 225 is a sensor that can emit a laser beam. Specifically, the detection end of the grasping detection unit 225 faces the inner end of the clamping opening where the document is inserted into the grasping assembly 222, and is used to detect whether the document is inserted in place and whether there is a document on the grasping assembly 222.

[0111] Please refer to Figure 7 and Figure 8, the grasping device 220 further includes a target detection unit 226 configured to detect whether there are documents at the target position in the target area 102 and the loading position in the loading area 101 when accessing documents. The target detection unit 226 is disposed on the grasping support frame 223. When the intelligent manipulator 200 is applied to a storage device, the grasping device 220 grasps the document and transports it to the target area 102, and detects whether there is a document at the designated target position. If there is a document, the storage is stopped and feedback is sent to the server to re-match the storage address to avoid direct storage of the document and causing damage to the document. When retrieving a document, it is detected whether there is a document at the target storage position. If there is no document, the document retrieval action is stopped and the system detects the reason. In this way, it is convenient for monitoring abnormal situations and ensures the smooth progress of document access. The target detection unit 226 is a sensor that can emit a laser beam.

[0112] Please also refer to Figure 7 and Figure 8 , the grasping device 220 further includes a guide frame 227.

[0113] The reading unit 224 is disposed on the guide frame 227 and faces the guiding structure 2271, and is used to identify and read the document information of the document located on the guiding structure 2271 when the grasping device 220 acquires the document. In this way, before storing in the target area 102, a designated storage position address is matched for the document to direct the document to be stored in the target area 102; when retrieving the document from the storage position, it is verified whether the retrieved document is the target document, making the whole operation faster and more accurate.

[0114] Please also refer to Figure 7 and Figure 8 , the guiding structure 2271 includes two guiding grooves 2001, which are respectively disposed on the guide frame 227. The two notch openings face each other, and the extending direction is the same as the direction in which the grasping assembly 222 grasps or sends out the document. The two side parts of the document are respectively inserted into the two guiding grooves 2001 and can slide relative to the guiding grooves 2001 in a directed manner.

[0115] Please refer to Figure 7 and Figure 8 simultaneously. The grasping device 220 further includes a connection assembly 228 connecting the guiding frame 227 and the grasping support frame 223. The connection assembly 228 includes a guiding rod 2281, an elastic member, and a guiding sliding connection assembly 2283. Among them, the guiding frame 227 has a head end 2002 with the same orientation as the grasping end of the grasping assembly 222 and a tail end 2003 opposite to the head end 2002. The guiding frame 227 is provided with a guiding hole (not marked in the figure) for the guiding rod 2281 to extend into on the end face of its tail end 2003 towards the head end 2002. One end of the guiding rod 2281 is fixed to the grasping support frame 223, and the other end extends into the guiding hole and is limited within the guiding hole. The elastic member is arranged on the guiding rod 2281 and abuts against the guiding frame 227 and the grasping support frame 223 at both ends respectively. In the natural state, the elastic member is in a compressed state. The tail of the guiding frame 227 away from the grasping support frame 223, and the grasping assembly 222 can be located between the two guiding grooves 2001 and can be away from the two guiding grooves 2001. When the grasping assembly 222 grasps or stores a document, the guiding frame 227 moves along the guiding rod 2281 towards the tail of the grasping support frame, and the grasping end of the grasping assembly 222 extends out from the head end 2002 of the guiding frame 227 to grasp or store the document. At this time, the elastic member is compressed, and the end of the guiding frame 227 abuts against the target area 102 or the loading area 101. The guiding sliding connection assembly 2283 is connected between the guiding frame 227 and the grasping support frame 223, which can enable the guiding frame 227 to slide directionally, improving the smoothness and stability of the telescopic movement of the guiding frame 227.

The visual detection unit is arranged on the grasping device 220. The main control unit controls the movement of the conveying mechanism 210 according to the deviation amount and transfers the grasping device 220 to a position aligned with the document to be grasped. In this way, it is not necessary to accurately position the document in the loading area 101, making the entire structure more intelligent.

[0119] Please also refer to Figures 9 to 11 that the intelligent forensics device 400 further includes a destruction device 440. The destruction device 440 includes a destruction driving source 442, a destruction frame 441, a movable frame 443 disposed on the destruction frame 441, and a destruction structure. The destruction frame 441 and the movable frame 443 jointly enclose a destruction space. The destruction space has a destruction position for inserting a certificate. The destruction position is disposed on the movable frame 443 or the destruction frame 441 facing the movable frame 443. The destruction structure is disposed in the destruction space and opposite to the destruction position. The destruction driving source 442 is controlled and connected to the main control unit. The movable frame 443 is connected to the destruction driving source 442 and is driven by the destruction driving source 442 to move the destruction structure closer to or away from the destruction position. After the forensics personnel receive a new certificate, they need to perform a destruction operation on the old or invalid certificate to avoid random disposal and being used by illegal persons.

[0120] There are two destruction spaces, namely a first destruction space 402 and a second destruction space 403. The first and second destruction spaces (402, 403) are respectively disposed on two opposite sides of the movable frame 443. They can be arranged left and right, or up and down. The arrangement orientation is not limited.

[0121] There are two destruction positions, namely a first destruction position 401 for inserting this type of certificate and a second destruction position 404 for inserting card-type certificates. The first destruction position 401 is disposed in the first destruction space 402, and the second destruction position 404 is disposed in the second destruction space 403. The first destruction position 401 is disposed on the movable frame 443 or the destruction frame 441 facing the movable frame 443, and the second destruction position 404 is disposed on the movable frame 443 or the destruction frame 441 facing the movable frame 443. This device can receive this type of certificate or card-type certificates. At the same time, it can destroy cards and this type of certificate.

[0122] On the operation side of the forensics housing 420, there is also a destruction opening. The destruction opening includes a card destruction opening 405 for inserting card-type certificates and a book destruction opening 406 for inserting this type of certificate. The card destruction opening 405 is opposite to the first destruction position 401, and the book destruction opening 406 is opposite to the second destruction position 404.

[0123] There are two destruction structures, namely a first destruction structure 444 disposed in the first destruction space 402 and opposite to the first destruction position 401, and a second destruction structure 445 disposed in the second destruction space 403 and opposite to the second destruction position 404.

[0124] Such as Figure 11As shown, the damage structure includes a damage tool 4441 and a pressing part 4442. Before damaging the certificate, the pressing part 4442 moves towards the damage position and jointly clamps the certificate to be damaged with the damage position. After the certificate is clamped, the damage driving source 442 drives the damage tool 4441 to damage the certificate, effectively avoiding the displacement of the certificate due to external force during the damage process, resulting in damage failure. When the certificate damage is completed, the damage tool 4441 is driven to disengage from the damaged certificate first. After the disengagement is completed, the pressing part 4442 is then driven to disengage from the damage position. In this way, it is convenient for the damaged certificate to quickly and smoothly disengage from the damage tool 4441. The first and second damage structures are both the above-mentioned damage structure. The damage tool 4441 can be a punching tool or a shearing tool. The movable frame 443 is driven by the damage driving source 442 to displace the movable frame 443 in the first damage space 402 and the second damage space 403.

[0125] The damage device 440 also includes a displacement driving source (not shown in the figure), which is connected to the damage frame 441 and is used to drive the damage frame 441 to displace towards or away from the damage socket direction to ensure the safe damage of the certificate. When the certificate is inserted into the damage position, the main control unit controls the displacement driving source to move and displace the damage frame 441 away from the damage socket direction. In this way, it can effectively prevent the damage personnel from taking away the certificate during the damage operation, resulting in the abnormal progress of the certificate damage; when the certificate damage is completed, the damage frame 441 will be driven to move towards the damage socket for reset, and the damage personnel can take away the damaged certificate.

[0126] The damage device 440 also includes a waste recycling structure 446, and the waste recycling structure 446 is fixed to the bottom of the damage frame 441 and is used to recycle the waste after the certificate is damaged.

[0127] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
