DETAILED DESCRIPTION
[0018] 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 other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0019] Please refer to Figures 1 to 12 In the embodiments of the present application, a file management system comprises a file bookshelf, a plurality of file boxes 101 placed on the file bookshelf, a management platform 102, a main RFID reader-writer 103, a three-axis moving device 10, a movable seat 20, and a file box pushing-out device 30.
[0020] The file box 101 is provided with an RFID passive tag 1011. The management platform 102 stores the information of the RFID passive tag 1011 and the file information in the file box 101 corresponding to the RFID passive tag 1011. The file box pushing-out device 30 and the main RFID reader-writer 103 are installed to the movable seat 20.
[0021] The triaxial moving device 10 drives the movable seat 20 to move so as to adjust the spatial position of the main RFID reader 103 and the file box pushing device 30. The file box pushing device 30 is used to push the file box 101 outwards.
[0022] The position of the RFID passive tag 1011 identified by the main RFID reader 103 is determined based on the RSSI positioning algorithm so as to determine the position of the file box 101 which needs to be pushed out, and the file box pushing device 30 is moved by the triaxial moving device 10 so as to align the file box 101 which needs to be pushed out.
[0023] The triaxial moving device 10 is a device which realizes the movement in three mutually perpendicular linear directions, i.e. the linear movement in the XYZ coordinate system. For the convenience of understanding, an example of a triaxial moving device which takes the screw nut transmission as the core is given. Specifically, the triaxial moving device 10 comprises a horizontal axis moving device 11, a vertical axis moving device 12 and a vertical axis moving device 13. The horizontal axis moving device 11 realizes the movement in the X axis direction. The vertical axis moving device 12 realizes the movement in the Y axis direction. The vertical axis moving device 13 realizes the movement in the Z axis direction.
[0024] The horizontal axis moving device 11 comprises a horizontal axis moving motor 111, a horizontal seat 112 and a horizontal sliding seat 113. The horizontal axis moving motor 111 is mounted to the horizontal seat 112. The horizontal axis moving motor 111 drives the horizontal sliding seat 113 to slide relative to the horizontal seat 112 through the screw nut transmission mechanism.
[0025] The vertical axis moving device 12 comprises a vertical axis moving motor 121, a vertical seat 122 and a vertical sliding seat 123. The vertical axis moving motor 121 is mounted to the vertical seat 122. The vertical axis moving motor 121 drives the vertical sliding seat 123 to slide relative to the vertical seat 122 through the screw nut transmission mechanism. The horizontal seat 112 is mounted to the vertical sliding seat 123.
[0026] The vertical axis moving device 13 comprises a vertical axis moving motor 131, a vertical seat 132 and a vertical sliding seat 133. The vertical axis moving motor 131 is mounted to the vertical seat 132. The vertical axis moving motor 131 drives the vertical sliding seat 133 to slide relative to the vertical seat 132 through the screw nut transmission mechanism. The vertical sliding seat 133 is mounted to the horizontal sliding seat 113.
[0027] The direction in which the horizontal sliding seat 113 slides relative to the horizontal seat 112, the direction in which the vertical sliding seat 123 slides relative to the vertical seat 122 and the direction in which the vertical sliding seat 123 slides relative to the vertical seat 122 are mutually perpendicular.
[0028] Because the span of the file bookshelf is relatively large, it can be supported and guided from both sides. Specifically, the three-axis moving device 10 further comprises an auxiliary guide rail 14. The right end of the cross seat 112 is mounted to the vertical sliding seat 123. The left end of the cross seat 112 slides along the auxiliary guide rail 14. The extension direction of the auxiliary guide rail 14 is parallel to the direction in which the vertical sliding seat 123 slides relative to the vertical seat 122.
[0029] In use, the file manager inputs the file to be taken out on the management platform 102. At this time, the position of the RFID passive tag 1011 identified by the main RFID reader 103 is determined based on the RSSI positioning algorithm, so as to locate the file box 101, and then the three-axis moving device 10 is used to move the file box pushing device 30 to align the file box 101 to be pushed out, and the file box 101 is pushed out by the file box pushing device 30, at this time the file box to be taken out by the file manager is pushed out, obviously protruding from other file boxes, which is convenient for the file manager to see.
[0030] The determination of the position of the RFID passive tag 1011 identified by the main RFID reader 103 based on the RSSI positioning algorithm is a prior art, and will not be described in detail here. Specifically, the distance-based positioning algorithm measures the received signal strength RSSI to measure the distance and position. As an optional way, the RFID passive tag 1011 can also be identified during movement to directly move based on the signal strength, so that the main RFID reader 103 aligns the RFID passive tag 1011, that is, the file box pushing device 30 aligns the file box 101 to be pushed out.
[0031] As a specific embodiment, the file box pushing device 30 comprises an electric push rod 31 and a push plate member 32 for contacting the file box 101 to push the file box 101 to move.
[0032] The electric push rod 31 is mounted to the movable seat 20. The electric push rod 31 pushes the push plate member 32 to move, so as to push the file to be taken out outward.
[0033] As a specific embodiment, the pushing plate 32 comprises a back plate part 321 and an upper pressing plate part 322. The upper pressing plate part 322 is connected to the top of the back plate part 321. The back plate part 321 is used to contact with the back of the file box 101 to push the file box 101 forward. The upper pressing plate part 322 is arranged at the top of the file box 101 to avoid the file box 101 from tilting forward or backward when moving. The upper pressing plate part 322 is arranged with a gap to the top of the file box 101 to prevent the upper pressing plate part 322 from abutting against the back of the file box 101 during the movement of the pushing plate 32. As an optional embodiment, the front end of the upper pressing plate part 322 can be arranged to be raised, i.e. the upper pressing plate part 322 is arranged in a flared inclined shape to facilitate the file box 101 to enter the area between the back plate part 321 and the upper pressing plate part 322.
[0034] As a preferred embodiment, the pushing plate 32 is provided with a lighting indicating element 3201. The upper pressing plate part 322 is arranged to be semi-transparent. The indicating light emitted by the lighting indicating element 3201 is transmitted outwardly through the upper pressing plate part 322. Specifically, the pushing plate 32 is an ABS plastic part and is arranged to be semi-transparent, and the preferred color is red. After the light emitted by the lighting indicating element 3201 enters the pushing plate 32, the upper pressing plate part 322 transmits red light outwardly, which facilitates the file management personnel to quickly see the file box and quickly remove the file to be taken out.
[0035] When the file boxes 101 are arranged loosely, the file boxes 101 do not contact with each other, and the lower file is referred to as Figure 12 When the file boxes 101 are arranged densely, one file box 101 is pushed out, and the adjacent file box can be pushed out under the action of friction, and the upper file is referred to as Figure 12 As a preferred embodiment, the file management system further comprises an anti-synchronization device 40 for preventing the forward movement of the file box 101 in contact with the file box 101 being pushed.
[0036] The anti-synchronization device 40 is installed to the movable seat 20. The file box 101 is provided with a lock hole 1012. The anti-synchronization device 40 comprises a lock box 41, a lock jaw 42, a connecting rod 43 and an electromagnetic push rod 44. The lock box 41 is fixed to the movable seat 20. The electromagnetic push rod 44 is installed to the lock box 41. The lock jaw 42 is rotatably installed to the lock box 41. The two ends of the connecting rod 43 are rotatably connected to the lock jaw 42 and the push rod of the electromagnetic push rod 44, respectively. The lock jaw 42 has a locking position and an unlocking position relative to the lock box 41. The electromagnetic push rod 44 drives the lock jaw 42 to rotate between the locking position and the unlocking position through the connecting rod 43. When the lock jaw 42 is in the locking position, the lock jaw 42 hooks the hole wall of the lock hole 1012 to lock the position of the file box 101. When the lock jaw 42 is in the unlocking position, the lock jaw 42 is released from the contact with the hole wall of the lock hole 1012 to release the file box 101.
[0037] The anti-synchronization device 40 locks the adjacent file box 101, thereby preventing the adjacent file box 101 from moving forward with the file box 101 being pushed. Referring to Figure 6 After the file boxes 101 on both sides are locked, they will not move with the middle file box 101.
[0038] As a specific embodiment, the number of the locking claws 42 and the connecting rods 43 is two. When the locking claws 42 are in the locking position, the two locking claws 42 are close to each other. When the locking claws 42 are in the unlocking position, the two locking claws 42 are away from each other.
[0039] As a specific embodiment, the number of the anti-synchronization devices 40 is two. The two anti-synchronization devices 40 are located on both sides of the electric push rod 31.
[0040] As a preferred embodiment, two auxiliary positioning RFID readers 51 are also installed on the movable seat 20. The two auxiliary positioning RFID readers 51 correspond to the two anti-synchronization devices 40 respectively. The two auxiliary positioning RFID readers 51 are located on both sides of the main RFID reader 103.
[0041] When the main RFID reader 103 moves to the position of the RFID passive tag 1011 of the file box 101 that needs to be pushed out, whether the file box 101 that needs to be pushed out is close to the adjacent file box 101 is determined based on the signal strength of the nearest RFID tag detected by the auxiliary positioning RFID reader 51. When the file box 101 that needs to be pushed out is close to the adjacent file box 101, the anti-synchronization device 40 locks the file box 101 corresponding to the nearest RFID tag detected by the auxiliary positioning RFID reader 51.
[0042] Specifically, when the signal strength of the nearest RFID tag detected by the auxiliary positioning RFID reader 51 reaches a preset threshold, it means that the adjacent file box 101 is close to the file box 101 that needs to be pushed out, and the adjacent file box 101 needs to be locked. When the signal strength of the nearest RFID tag detected by the auxiliary positioning RFID reader 51 does not reach the preset threshold, it means that the nearest file box 101 is relatively far away, i.e., not close, and locking is not needed. When locking is needed, the corresponding anti-synchronization device 40 is controlled to lock. When locking is not needed, the corresponding anti-synchronization device 40 is not controlled to lock.
[0043] The control of the three-axis moving device 10, the file box pushing-out device 30 and the anti-synchronization device 40 can be integrated in the management platform 102, or controlled by the management platform 102 as an independent control module.
[0044] When the archives are archived, the archive box 101 is directly placed on the archive bookshelf, and through the main RFID reader 103, the returned archives can be recorded into the management platform 102. As an optional implementation, a separate antenna can be provided to read the RFID tag to realize the warehousing operation.
[0045] The front of the archive box 101 is provided with an electronic ink screen to display the content of the archives. Because the refresh of the electronic ink is discontinuous, each refresh can keep the current graphics, and even if the power is lost, the clear image can be saved. Because the electronic ink has a bistable effect (hysteresis effect), by using this effect, a positive voltage is applied to the screen surface layer to attract negative charges, that is, white can be displayed on the screen. At this time, the power is off, and the charge position will not move, so the image can be saved.
[0046] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
[0047] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.
