Abstract

The invention relates to a seal use identification method, a seal evidence obtaining method and intelligent seal equipment. The seal use identification method comprises the following steps: carrying out whole-process real-time detection on a surface contact condition between a seal pattern surface of a seal body moving to a seal outlet on the inner side of an equipment shell and a to-be-sealed file; judging and processing according to the detected surface contact condition; when the seal pattern surface is in contact with the to-be-stamped file surface, judging that the seal currently executes the stamping operation; otherwise, judging that the seal does not execute the stamping operation at present. Once surface contact is detected, it is judged that the seal currently executes the stamping operation. Due to the fact that face contact real-time detection aiming at the whole process is executed, it is ensured that the recognition and detection work is executed all the time in the whole process, even if unneeded stamping and rubbing operation occurs, it can be recognized that the seal executes the stamping operation at the first time, and the use safety of the seal is enhanced; and the seal use potential safety hazard caused by missing of the rubbing operation and non-triggering of the traditional seal pressure sensing detection is avoided.

Description

Technical Field

[0001] The present invention relates to the field of seal equipment, and in particular to a seal use identification method, a seal evidence collection method and an intelligent seal equipment. Background Art

[0002] The existing seal equipment mainly includes an equipment housing, a seal carrier, a seal body, an ink box, a pressing part that drives the seal carrier to move up and down in the equipment housing, and an ink box flipping mechanism that drives the ink box to flip. The equipment housing has an outlet for the seal body to enter and exit at the bottom. The seal body is set on the seal carrier. The seal body has a seal pattern surface. The seal body can move to the outlet with the moving seal carrier, and then the seal pattern surface is stamped on the document to be stamped.

[0003] In order to identify the use of the seal, a seal pressure sensor that detects the pressure on the seal body pattern surface is usually installed on the seal carrier. The seal pressure sensor specifically detects the pressure generated when the seal body pattern surface touches the document to be stamped. Once the seal pressure sensor detects pressure once, it is determined that the seal device has completed a stamping operation, that is, the seal has been used once; and according to needs, the current moment when the seal device is determined to have completed a stamping operation based on the pressure detected by the seal pressure sensor is used as the starting point of the seal evidence collection time, and the relevant images of the seal use process are collected according to the predetermined evidence collection frequency, and the association between the seal use and the relevant images each time the seal is used is established, so as to facilitate the subsequent evidence collection of the seal use.

[0004] However, the existing seal use identification method mentioned above has shortcomings: the pressure on the seal body pattern surface must reach a preset pressure threshold in order to be detected by the seal pressure sensor. Once the seal body pattern surface covered with ink lightly touches the paper document and the pressure generated by the light touch does not reach the preset pressure threshold, the seal pressure sensor cannot detect the current pressure on the seal body pattern surface, and thus cannot successfully identify the current seal use event, which will also cause serious risks of seal use. Not only that, the starting point of the evidence collection time is the current moment when the seal device completes a stamping operation based on the pressure detected by the seal pressure sensor. Once the seal is actually used but the seal pressure sensor fails to successfully identify the seal as being used due to insufficient pressure or other circumstances, the seal use will be missed, and the related image evidence collection operation for the missed seal use cannot be initiated, which is not conducive to the subsequent seal use evidence collection. Summary of the invention

[0080] The present invention is further described in detail below with reference to the accompanying drawings.

[0081] This embodiment provides a seal use recognition method that can accurately recognize the seal operation. Figure 1 As shown, the seal usage identification method of this embodiment includes the following steps:

[0082] Step 1, performing real-time detection of the contact between the seal pattern surface of the seal body moving from the inner side of the device housing to the seal outlet and the document to be stamped; wherein the whole process is the entire movement process of the seal body from the inner side of the device housing to the outer side of the seal outlet;

[0083] Step 2: Make a judgment based on the detected surface contact situation:

[0084] When the seal pattern surface contacts the surface of the document to be stamped, it is determined that the seal is currently performing a stamping operation; otherwise, it is determined that the seal is currently not performing a stamping operation.

[0085] It should be noted that the seal use identification method of this embodiment detects the surface contact between the seal pattern surface of the seal body and the document to be stamped in real time during the whole process of the seal body moving from the inside of the device housing to the seal outlet. Once the surface contact between the two is detected, it is determined that the seal is currently performing a stamping operation. Since the identification detection is not started until the seal pattern surface reaches the seal outlet, but the real-time detection of the surface contact of the whole process is performed, it is ensured that the identification detection work is always performed during the whole process. Even if an unnecessary stamping operation occurs, it will be recognized as the stamping operation of the seal at the first time, thereby enhancing the safety of the seal use and avoiding the safety hazards of the seal use caused by missing the stamping operation and the failure of the traditional seal pressure sensing detection to be triggered.

[0086] Specifically, for the seal usage identification method of this embodiment, at least one of the following methods can be used as needed to detect the surface contact between the seal pattern surface of the seal body and the document to be stamped. Specifically:

[0087] The first implementation method: The process of detecting the contact between the seal pattern surface of the seal body and the document to be stamped includes the following steps a1 to a3:

[0088] Step a1, obtaining a target image including a seal pattern surface of a seal body and a document to be stamped;

[0089] Step a2, performing image recognition processing on the acquired target image;

[0090] Step a3: make a judgment based on the image recognition processing result:

[0091] When it is recognized that the seal pattern surface is in surface contact with the document to be stamped, it is determined that the seal pattern surface of the seal body and the document to be stamped have surface contact; otherwise, it is determined that the seal pattern surface of the seal body and the document to be stamped have not surface contact.

[0092] For the first implementation method mentioned above, in order to improve the detection accuracy of whether surface contact occurs between the seal pattern surface and the document to be stamped, so as to improve the recognition rate of stamping operations, the seal usage identification method of this embodiment also includes: making a judgment on whether the seal pattern surface of the seal body is in surface contact with the surface to be stamped of the document to be stamped before the seal carrier moves to the stamp outlet: when the seal pattern surface is in surface contact with the surface to be stamped, it is determined that the seal is currently performing a stamping operation; otherwise, it is determined that the seal is not currently performing a stamping operation.

[0093] The second implementation method is as follows: a seal carrier is provided inside the device housing and can be driven to move back and forth between the inside of the device housing and the seal outlet; the seal body is provided on the seal carrier, and the seal pattern surface of the seal body is located at a preset distance position from the lower end surface of the seal carrier, where the preset distance is greater than zero; wherein the process of detecting the surface contact between the seal pattern surface of the seal body and the document to be stamped includes the following steps b1 to b4:

[0094] Step b1, detecting the position of the seal carrier when it moves in the device housing, and obtaining the seal pattern surface position of the seal body according to the detected seal carrier position and the preset distance; wherein the seal pattern surface position is the sum of the detected seal carrier position and the preset distance;

[0095] Step b2, judging whether the seal pattern surface has moved to the outside of the seal outlet according to the obtained seal pattern surface position:

[0096] When the seal pattern surface moves to the outside of the seal outlet, go to step b3; otherwise, go to step b1;

[0097] Step b3, detecting whether there is a document to be stamped below the stamp outlet;

[0098] Step b4, making a judgment based on the detection result of the document to be stamped:

[0099] When a document to be stamped appears, it is determined that the seal pattern surface has produced surface contact with the document to be stamped; otherwise, it is determined that the seal pattern surface has not produced surface contact with the document to be stamped.

[0100] For the above-mentioned second implementation method, more specifically, a positioning identifier is set on the horizontal edge of the bottom of the seal carrier, and the seal pattern surface of the seal body is located at the preset distance position below the positioning identifier; the seal pattern surface position of the seal body is the sum of the detected positioning identifier position and the preset distance.

[0101] The third implementation method is to set a seal carrier inside the device housing and be driven to move back and forth between the inside of the device housing and the seal outlet, the seal body is set on the seal carrier, and the seal pattern surface of the seal body is located below the lower end surface of the seal carrier; wherein the process of detecting the surface contact between the seal pattern surface of the seal body and the document to be stamped includes the following steps:

[0102] Step c1, detecting the position of the seal carrier when it moves in the device housing; wherein,

[0103] Step c2, making a judgment based on the detected seal carrier position:

[0104] When the seal carrier moves to the seal outlet of the device housing, the process proceeds to step c3; otherwise, the process proceeds to step c1;

[0105] Step c3, detecting whether a to-be-stamped surface of the document to be stamped appears below the seal pattern surface of the seal body;

[0106] Step c4, making a judgment based on the detected surface to be stamped:

[0107] When the surface to be stamped is detected, it is determined that the seal pattern surface of the seal body has made surface contact with the document to be stamped; otherwise, it is determined that the seal pattern surface of the seal body has not made surface contact with the document to be stamped.

[0108] For the above-mentioned third implementation method, in order to improve the detection accuracy of whether surface contact occurs between the seal pattern surface and the document to be stamped, so as to improve the recognition rate of stamping operations, the seal usage identification method of this embodiment also includes: making a judgment on whether the seal pattern surface of the seal body is in surface contact with the surface to be stamped of the document to be stamped before the seal carrier moves to the stamp outlet: when the seal pattern surface is in surface contact with the surface to be stamped, it is determined that the seal is currently performing a stamping operation; otherwise, it is determined that the seal is not currently performing a stamping operation.

[0109] Of course, in order to significantly improve the recognition rate of the stamping operation of the stamp device, for any of the above three implementations, the seal use recognition method of this embodiment also includes performing a seal use auxiliary recognition operation. Specifically, the seal use auxiliary recognition operation includes the following steps:

[0110] Step d1, performing real-time detection of whether the seal pattern surface of the seal body moving from the inner side of the device housing to the seal outlet is subjected to contact pressure during the whole process; wherein the whole process is the whole movement process of the seal body from the inner side of the device housing to the outer side of the seal outlet;

[0111] Step d2, making a judgment based on the detected contact pressure:

[0112] When the seal pattern surface is subjected to contact pressure, it is determined that the seal is currently performing a stamping operation; otherwise, it is determined that the seal is currently not performing a stamping operation.

[0113] This embodiment provides two seal evidence collection methods using the seal usage identification method described above. Figure 2 As shown, the first seal evidence collection method provided in this embodiment includes the following steps s1 to s4:

[0114] Step s1, obtaining seal usage recognition results;

[0115] Step s2, process the obtained seal using the recognition result:

[0116] When it is determined that the seal is currently performing a stamping operation, the process proceeds to step s3; otherwise, the process proceeds to step s1;

[0117] Step s3, at each pre-specified evidence collection time point, respectively and simultaneously collect an external document image of the document to be stamped located on the outside of the device housing and an internal document image of the document to be stamped located on the inside of the device housing, and use the external document image and internal document image collected at the same evidence collection time point as evidence collection image information corresponding to the same evidence collection time point;

[0118] Step s4, establishing a one-to-one correspondence between each evidence collection time point and its corresponding evidence collection image information for use in evidence collection.

[0119] In the first seal evidence collection method described above, the seal usage identification result in step s1 is obtained by using the seal usage identification method using the second implementation method or the third implementation method.

[0120] It should be noted that in the first seal forensics method mentioned above, by simultaneously collecting the document image of the document to be stamped located on the inside of the device shell and the document image located on the outside of the device shell at each pre-specified evidence collection time point, the stamp scene image of the document part below the seal body which is the key area of ​​the stamp scene is collected, thereby improving the accuracy of subsequent stamp forensics operations.

[0121] See also Figure 2 As shown, the second seal evidence collection method provided in this embodiment includes the following steps m1 to m4:

[0122] Step m1, obtaining seal usage recognition results;

[0123] Step m2: Process the obtained seal using the recognition result:

[0124] When it is determined that the seal is currently performing a stamping operation, the process proceeds to step m3; otherwise, the process proceeds to step m1;

[0125] Step m3, at each pre-specified evidence collection time point, respectively and simultaneously collect an external document image of the document to be stamped located on the outside of the device housing and an internal document image of the document to be stamped located on the inside of the device housing, and use the external document image and internal document image collected at the same evidence collection time point as evidence collection image information corresponding to the same evidence collection time point;

[0126] Step m4, establishing a one-to-one correspondence between each evidence collection time point and its corresponding evidence collection image information for use in evidence collection.

[0127] It should be noted that in the above-mentioned first seal forensics method and the second seal forensics method, the document image of the document to be stamped located on the inside of the device shell and the document image located on the outside of the device shell are simultaneously collected at each pre-designated evidence collection time point, thereby collecting the stamp scene image of the document part below the seal body which is the key area of ​​the stamp scene, thereby improving the accuracy of the subsequent stamp forensics operation.

[0128] In addition, according to actual needs, in the above-mentioned seal evidence collection methods, the pre-designated evidence collection time points are at least one of the following evidence collection time points: the first evidence collection time point is the moment when it is determined that the seal is currently performing a stamping operation; the second evidence collection time point is the moment when it is determined that the seal has completed the stamping operation and the seal body has risen to the predetermined position on the inner side of the device shell; the third evidence collection time point is the moment before the seal performs the stamping operation and the seal body moves down to the predetermined position on the inner side of the device shell toward the seal outlet; the fourth evidence collection time point is the moment corresponding to when the ink box in the seal device shell is flipped to a vertical position close to the inner wall of the device shell.

[0129] This embodiment also provides a smart seal device that can implement the second seal evidence collection method described above.

The driving mechanism drives the driven member to switch the moving direction under control, so as to realize the switching adjustment of the driven member to the tight fitting state between the hanger and the seal carrier and the switching adjustment of the pressing member to the pressing state. For example, the driving mechanism 74 here adopts a driving motor, and the driven member is connected to the driving mechanism in a transmission manner; the controller is connected to the driving mechanism and is configured to control the driving mechanism to drive the driven member to switch the moving direction.

[0135] Specifically, the driven part 71 of this embodiment includes a first controlled matching part 711 and a second controlled matching part 712. The first controlled matching part 711 is configured to move with the driven part to achieve a tight matching state between the seal carrier and the hanger and release the tight matching state; the second controlled matching part 712 is configured to move with the driven part to achieve a non-depressible state of the pressing part and release the non-depressible state of the pressing part.

[0136] In order to cooperate with the driven part to adjust the tight fit between the stamp carrier and the hanger and the pressing part, see Figure 8As shown, in this embodiment, the seal carrier 2 is provided with a first snap groove 21 for the first controlled matching part 711 of the driven part 71 to be snapped in and moved out, and a second snap groove 22 for the first controlled matching part 711 of the driven part 71 to be snapped in and moved out; a push lock bracket 11 is provided on the inner side of the device housing 1 of the seal device, and the push lock bracket 11 is fixed to the device housing 1, and the push lock bracket 11 has a lock groove 110 for the second controlled matching part 712 of the driven part 71 to be snapped in and moved out.

[0137] In the seal lock mechanism of this embodiment, the first controlled matching portion 711 of the driven member 71 is configured to switch and adjust between the first buckle slot 21 and the second buckle slot 22 as the driven member reciprocates and rotates after being driven, and the buckle slot 110 of the press lock bracket 11 is an arc-shaped slot. The first buckle slot 21 and the second buckle slot 22 are two slots connected to each other. In this way, the driven member can rotate between the first buckle slot and the second buckle slot by rotating.

[0138] As an implementation method of the above-mentioned driven component structure, see Figure 7 As shown, the driven part 71 in this embodiment is a lock latch, the first controlled matching part 711 is the latch body of the lock latch, and the second controlled matching part 712 is the lock tongue of the lock latch. The lock tongue is configured to be able to perform elastic telescopic movement back and forth along the axial direction of the latch body. For example, the latch body is formed with an inner cavity C, and the inner cavity C is provided with an elastic member 72 that can perform elastic telescopic movement along the axial direction of the inner cavity. The elastic member can be a spring, one end of the elastic member is connected to the lock tongue, and the other end of the elastic member is fixed in the inner cavity. In this way, as long as the lock tongue is subjected to a squeezing force, the lock tongue will move toward the inner side of the inner cavity. Conversely, when the lock tongue is not subjected to a squeezing force, the lock tongue will move toward the outer side of the inner cavity under the action of the elastic force of the elastic member.

[0139] In order to timely grasp whether the first controlled matching portion of the driven component is correspondingly engaged with the first buckle slot and the second buckle slot of the stamp carrier, so that the controller can control the driving work of the driving mechanism according to the buckle situation, see Figure 5As shown, the seal lock mechanism of this embodiment also includes a buckle state detection device 73 for detecting the buckle state of the first controlled matching portion 711 with the first buckle slot 21 and the second buckle slot 22 respectively, and the buckle state detection device 73 is connected to the controller; the buckle state detection device 73 is configured to be set inside the device housing. Among them, the buckle state detection device is preferably set above the driven part 71 and located between the first buckle slot 21 and the second buckle slot 22. For example, in this embodiment, the buckle state detection device adopts a pressure sensor, and the pressure sensor is set at a position above the lock latch of the driven part 71. In this way, once the lock pin is not inserted into the first lock slot of the seal carrier, and is not inserted into the second lock slot of the seal carrier, and the lock tongue of the lock pin is not inserted into the lock slot of the push lock bracket, the lock pin at this time will be not locked by any slot body, causing the lock pin to press against the pressure sensor above, and then after the pressure sensor sends the detected pressure signal to the controller, the controller can determine that the driven part is neither locked with the seal carrier nor with the push lock bracket, and then the controller can make the seal device issue an unlocked prompt message.

[0140] Of course, when the driven member 71 stays at a position between the first buckle slot 21 and the second buckle slot 22 , the driven member 71 is located below the buckle state detection device 73 .

[0141] In order to improve the detection accuracy of the stamping operation, the stamping monitoring mechanism of this embodiment also includes a stamp pressure detector (not shown in the figure) for detecting the pressure on the stamp body, and the stamp pressure detector is connected to the controller. The stamp pressure detector is arranged on the stamp hanger 12. In this way, on the basis of judging and identifying the stamping operation based on the images collected by the first image acquisition device 41 and the second image acquisition device 42, the stamping can be further judged and identified based on the pressure on the stamp pattern surface of the stamp body, which greatly improves the recognition rate of the stamping operation.

[0142] The working principle of the seal locking mechanism in this embodiment is described as follows:

[0143] (1) When the seal carrier in the seal device needs to be locked with the hanger, and the pressing member cannot move downward toward the lower end of the device housing, the controller controls the driving mechanism to work according to the received command, so that the driving mechanism drives the driven member to move in one direction until the first controlled matching portion of the driven member is locked in the first locking groove of the seal carrier and the second controlled matching portion of the driven member is locked in the locking groove of the pressing lock bracket, see Figure 8As shown, since the driven member and the driving mechanism are both arranged on the hanger, the hanger and the seal carrier are locked by the driven member, and the hanger and the press lock bracket fixed in the device housing are also locked by the driven member, so that the hanger and the seal carrier, as well as the hanger and the press lock bracket are in a locked state. Even if downward pressure is applied to the pressing member in this state, because the hanger has been locked and cannot move downward, the seal body on the seal carrier will not move downward either, resulting in the pressing member being unable to make a downward pressing movement toward the lower end of the device housing;

[0144] (2) When the seal carrier in the seal device needs to be locked with the hanger, and the pressing member is required to be able to press downward toward the lower end of the device housing, the controller controls the driving mechanism according to the instruction to drive the pressed member to move in another direction, so that the first controlled matching portion of the driven member moves out of the first buckle slot of the seal carrier and is locked into the second buckle slot of the seal carrier, and the second controlled matching portion of the driven member moves out of the buckle slot of the press lock bracket, see Fig. 9 As shown, at this time, the hanger and the seal carrier are still locked by the driven member, while the lock state of the hanger and the push lock bracket is released, so that when downward pressure is applied to the pressing member in this state, the hanger is not locked with the push lock bracket, and the hanger can move downward toward the lower end of the device housing with the pressing member, and the hanger moves downward with the seal carrier, and then the seal body also moves downward with the seal carrier, so that the seal body moves to the outside of the device housing to cooperate with the subsequent stamping operation;

[0145] (3) When the seal carrier needs to be separated and disassembled from the hanger, the controller controls the driving mechanism according to the instruction to drive the pressure-bearing part to move in one direction, so that the first controlled matching part of the driven part is neither inserted into the first buckle groove of the seal carrier nor inserted into the second buckle groove of the seal carrier. In this way, the seal carrier and the hanger are always in an unlocked buckle state, so that the seal carrier can be separated and disassembled from the hanger as needed.

[0146] In the smart seal device of this embodiment, a seal locking mechanism is set up, so that the seal locking mechanism includes a driven part, a driving mechanism and a controller. The controller is connected to the driving mechanism and is configured to control the driving mechanism to drive the driven part to switch the moving direction, so that the driven part can move in different directions respectively under the drive of the driving mechanism, so as to realize the switching adjustment of the driven part to the tight fitting state between the hanger and the seal carrier and the switching adjustment of the pressing state of the pressing part, so that the state of the driven part can be adjusted as needed to complete the adjustment control of the tight fitting state between the hanger and the seal carrier and the pressing state of the pressing part.

[0147] Considering that after the driving mechanism drives the seal body to the outside of the seal outlet of the device housing, once someone applies continuous downward pressure to the pressing member in an attempt to prevent the seal body from being retracted to the inside of the device housing, the driving mechanism cannot retract the seal body to the inside of the seal device housing, which may cause the seal body to be exposed to the outside and be illegally stamped. Therefore, the smart seal device of this embodiment is further provided with a seal driving mechanism with a seal retracting function. Specifically, see Figure 5 , Figure 8 , Fig. 9 , Fig.11 and Fig.12 As shown, the seal driving mechanism of this embodiment includes a pressing member 6 and a seal retracting mechanism, wherein the pressing member 6 is configured to be slidable back and forth along the axial direction of the device housing 1 of the seal device on the device housing 1, and the pressing member 6 is sleeved on the outside of the device housing 1; the seal retracting mechanism has a controller and a driving device, the controller is configured to receive a start instruction for executing a seal operation and an end instruction for ending the seal operation; the driving device is controlled by the controller, and the driving device is configured to cooperate with the pressing member 6 to output a driving force for driving the seal body 3 to move from the inside of the device housing 1 to the outside of the device housing 1 or to eliminate the driving force.

[0148] That is to say, when the driving device and the pressing piece are in a state of mutual cooperation, the pressing piece and the driving device are in a transmission cooperation state, and the driving device can output a driving force to drive the seal body from the inside of the device housing to the outside of the device housing; when the driving device and the pressing piece are in another state, the pressing piece and the driving device are no longer in a transmission cooperation state, and the driving device eliminates the above-mentioned driving force, that is, it is impossible to drive the seal body from the inside of the device housing to the outside of the device housing.

[0149] It should be noted that in this embodiment, the start instruction for executing the seal operation and the end instruction for ending the seal operation received by the controller can be set as instructions sent by a remote server or instructions generated by the seal device itself using the seal drive mechanism.

[0150] For example: if the above-mentioned "start instruction" and "end instruction" are instructions sent by a remote server, it can be known that the controller in the seal drive mechanism here needs to communicate with the remote server directly or indirectly; if the above-mentioned "start instruction" and "end instruction" are instructions generated by the seal device itself, the seal device can be provided with a control device that controls the generation of the above-mentioned "start instruction" and "end instruction".

[0151] Specifically, in the seal driving mechanism of this embodiment, the driving device includes an elastic reset member 81 and two driving components. The elastic reset member 81 is configured to be elastically and telescopically arranged on the inner side of the device housing 1 along the axial direction of the device housing 1. The first end of the elastic reset member is configured to be arranged on the inner side of the device housing and above the seal body 3. The second end of the elastic reset member is configured to be connected to the seal body 3 directly or indirectly. The elastic reset member is a reset spring. The two driving components are both arranged on the inner side of the device housing, and the two driving components are symmetrically arranged at the two sides of the seal body, for example, one driving component is arranged at the left side of the seal body, and the other driving component is arranged at the right side of the seal body.

[0152] For each driving assembly, the driving assembly has a driving force output device and a transmission coupling member, the driving force output device outputs the driving force; the transmission coupling member cooperates with the driving force output device and is in transmission cooperation with the pressing member, and the transmission coupling member is configured to be in transmission cooperation with the pressing member so as to directly or indirectly act the driving force output by the driving force output device on the seal body or release the transmission cooperation with the pressing member. In other words, the transmission coupling member here is responsible for realizing the transmission cooperation between the driving force output device and the pressing member.

[0153] Specifically, in the above-mentioned seal driving mechanism, the driving force output device is a driving motor 82, and the driving motor 82 has a rotating shaft 821. The driving motor 82 is connected to the controller and is configured to output a positive driving force for driving the rotating shaft 821 to rotate in a first direction and a reverse driving force for driving the rotating shaft 821 to rotate in a second direction under the control of the controller, and the first direction and the second direction are opposite to each other; the transmission coupling member is a locking member 83 that can be matched with the rotating shaft 821 in transmission, and the locking member 83 is configured to complete a snap connection with the pressing member 6 as the rotating shaft 821 rotates in one direction and to release the lock connection with the pressing member 6 as the rotating shaft 821 rotates in another direction. For example, for the driving component on one side of the seal body, the locking member 83 completes a snap connection with the pressing member as the rotating shaft 821 rotates in the positive direction, and the locking member 83 releases the above-mentioned snap connection with the pressing member as the rotating shaft 821 rotates in the reverse direction. As for the driving assembly on the other side of the seal body, the locking member 83 on the other side is configured to complete the snap connection with the pressing member as the rotating shaft 821 rotates in the reverse direction, and the locking member 83 releases the above-mentioned snap connection with the pressing member as the rotating shaft 821 rotates in the forward direction.

[0154] In this embodiment, the direction of the rotational force of the rotating shaft to which the locking member 83 is subjected when the transmission cooperation with the pressing member 6 is released is consistent with the direction of the artificial pressing force to which the pressing member is subjected when performing the seal operation. Specifically, the direction of the artificial pressing force to which the pressing member is subjected when performing the seal operation is downward in the axial direction of the device housing, and the rotational force of the rotating shaft to which the locking member is subjected when the transmission cooperation with the pressing member is released is also downward in the axial direction of the device housing. In this embodiment, the driving device includes four elastic reset members 81, and the four elastic reset members are respectively arranged at the positions of the upper left corner, the lower left corner, the upper right corner and the lower right corner of the seal body.

[0155] In order to achieve locking cooperation between the pressing member and the driving device, in this embodiment, the pressing member 6 has a buckle groove 60 that is correspondingly engaged and removed by the locking member 83 as the rotating shaft 821 rotates. The buckle groove 60 is preferably arranged on the inner side wall of the pressing member, and the buckle groove 60 is formed with a slope section 60a that is engaged and removed by the locking member 83.

[0156] As a way for the seal driving mechanism to drive the seal body to move to the outside of the device housing and to be retracted to the inside of the device housing, in this embodiment, a seal hanger 12 for mounting the seal body is provided on the inside of the device housing 1, the driving device is provided on the seal hanger 12, and the second end of the elastic reset member 81 is connected to the seal hanger 12. Of course, because the seal driving mechanism in this embodiment adopts four elastic reset members, the four elastic reset members here are respectively provided on the four corners (upper left corner, lower left corner, upper right corner and lower right corner) of the seal hanger 12.

[0157] In order to cooperate with the pressing piece to move axially downwardly of the device housing to drive the seal body to move out of the device housing through the locking piece, a sliding track 100 extending axially along the device housing is formed on the device housing 1 of this embodiment. The sliding track 100 is configured to cooperate with the locking piece 83 after the pressing piece transmission cooperation is released so that the locking piece slides back and forth along the axial direction of the device housing.

[0158] As a structural implementation of the lock member, in this embodiment, the lock member 83 has a snap portion 831 and a stopper 832. The snap portion 831 is engaged with the snap slot 60 or is removed from the snap slot 60; the stopper 832 is configured to slide back and forth in the sliding area defined by the upper and lower ends of the sliding track 100 in the sliding unlocking state. Of course, when the stopper of the lock member is restricted in the sliding area defined by the upper and lower ends of the sliding track, the stopper cannot be removed from the lower end of the sliding track after being subjected to force, which can prevent others from trying to forcibly pull the seal hanger located in the device housing out of the device housing through the seal outlet.

[0159] In order to achieve transmission cooperation between the locking member and the rotating shaft, the locking member 83 has a rotating hole (not shown in the figure) through which one end of the rotating shaft 821 passes or penetrates, and the locking member 83 achieves transmission cooperation with the rotating shaft 821 through the rotating hole.

[0160] The working principle of the seal driving mechanism in this embodiment is described as follows:

[0161] When the controller of the seal driving mechanism receives the start instruction for executing the seal operation, the controller controls the driving motor in the driving assembly on one side to work, so that the rotating shaft of the driving motor on this side rotates in the positive direction, and the locking member also rotates in the positive direction with the positive rotation of the rotating shaft, so that the locking portion of the locking member is locked in the locking groove of the driving member, and the driving member and the locking member are then manually pressed down along the axial direction of the seal device housing. The driving member drives the seal hanger with the seal body mounted on it to move downward through the locking member, and the locking member moves downward along the sliding track, while the elastic reset member in the device housing is continuously stretched by the seal hanger until the seal body moves from the inner side of the device housing to the outer side of the device housing through the seal outlet, thereby completing the seal operation;

[0162] When the controller of the seal driving mechanism receives the end instruction of ending the seal operation, the controller controls the driving motor in the driving assembly on this side to work, so that the rotating shaft of the driving motor rotates in the opposite direction, and the locking member also rotates in the opposite direction with the reverse rotation of the rotating shaft, so that the locking portion of the locking member moves out of the locking groove of the driving member. At this time, there is no locking connection relationship between the driving member and the locking member, and the transmission matching state between the driving member and the locking member is released. The driving member cannot apply force to the locking member. Since there is no resistance of the driving member to the movement of the locking member, the elastic reset member that was originally stretched will produce an elastic reset movement toward the inner side of the device shell, and the seal hanger will produce an upward movement toward the upper inner side of the seal device shell with the elastic reset movement of the elastic reset member. The locking member moves upward along the sliding track on the device shell until the stop portion of the locking member is blocked by the upper end of the sliding track. At this time, the driving mechanism completes the operation of retracting the seal body.

[0163] It should be noted that when the controller of the seal driving mechanism receives the end instruction to end the seal operation, the driving device inside the device housing will automatically move its locking member out of the buckle groove of the pressing member. Even if someone tries to continue to apply downward pressure to the driving member along the axial direction of the seal device housing in an attempt to keep the seal body on the outside of the device housing, the driving member cannot achieve transmission cooperation with the locking member, and the driving member cannot prevent the elastic reset member inside the device housing from driving the seal body to move upward. Moreover, because the artificial pressing force applied to the driving member by an outsider is downward along the axis of the device housing, the direction of the artificial pressing force is consistent with the direction of the rotational force of the rotating shaft on which the locking member is exerted when it is moved out of the buckle groove, thereby making the original artificial pressing force that attempted to hinder the retraction of the seal body become an auxiliary force that helps the locking member move out of the buckle groove, thereby avoiding the adverse effect of the artificial pressing force on the retraction movement of the seal body.

[0164] In addition, it should be noted that in actual applications, for the above-mentioned seal driving mechanism, the above-mentioned driving component can also be configured as follows as needed: the driving component located on one side of the seal body is an electromagnetic device that can output magnetic attraction, and the electromagnetic device outputs magnetic attraction to achieve transmission coordination with the pressing member, that is, the electromagnetic device achieves transmission coordination with the pressing member through magnetic attraction with the pressing member. After the magnetic attraction output by the electromagnetic device disappears, the electromagnetic device releases the transmission coordination with the pressing member.

[0165] In the seal driving mechanism of this embodiment, the seal driving mechanism includes a pressing piece and a seal retracting mechanism, the pressing piece is configured to be slidable back and forth along the axial direction of the device housing of the seal device on the device housing, the seal retracting mechanism has a controller and a driving device cooperating with the pressing piece, the driving device can cooperate with the pressing piece according to the start instruction or end instruction for the seal operation received by the controller to output a driving force for driving the seal body to move out of the device housing from the inside to the outside of the device housing or eliminate the driving force, thereby achieving the effect of automatically retracting the seal body outside the seal device housing to the inside of the device housing according to the control instruction;

[0166] The driving device of the seal driving mechanism includes an elastic reset part, a driving motor and a locking part. The locking part is configured to complete a snap connection with the pressing part as the rotating shaft rotates in one direction and to release the snap connection with the pressing part as the rotating shaft rotates in another direction. The rotational force of the rotating shaft applied to the locking part when the locking part releases the transmission cooperation with the pressing part is consistent with the direction of the artificial pressing force applied to the pressing part when the pressing part performs the seal operation. Therefore, even if artificial pressing force is applied to the driving part in an attempt to retain the seal body on the outside of the device housing, the artificial pressing force will be converted into an auxiliary force to assist the locking part in releasing the snap state from the pressing part, thereby avoiding the adverse effect of the artificial pressing force on the retracting movement of the seal body and ensuring that the seal body can be automatically retracted to the inside of the device housing by the driving device.

[0167] Furthermore, in order to accurately monitor the stamping operation and reduce the risk of stamping without permission, in this embodiment, the smart stamp device also includes a stamping monitoring mechanism. Specifically, the stamping monitoring mechanism includes a first camera device 41 and a processor, the processor is connected to the first camera device 41, and the first camera device 41 is configured to be set to the inner side of the stamp device housing 1 and collect the image of the stamp body moving from the inner side of the device housing 1 to the stamp outlet 10 of the device housing; for example, the first camera device 41 is set on the inner side of the device housing.

[0168] In the stamp monitoring mechanism of this embodiment, the image of the seal body when it moves with the seal carrier in the device housing is collected by the first camera device, and the collected seal body image is sent to the processor, and then the processor processes the received seal body image to identify whether the seal body is in contact with the document to be stamped at the stamp outlet. Once it is identified that the seal body is in contact with the document to be stamped at the stamp outlet, it is determined that the seal device has completed a stamping action. Since the processor identifies the image of the entire process of the seal body moving from the inside of the seal device housing to the outside of the stamp outlet, that is, the entire process of the seal body moving from the inside of the device housing to the outside of the stamp outlet will be collected by the first camera device. The seal body image is not collected until the seal body moves to the outside of the stamp outlet, thereby ensuring that the recognition operation for the moving position of the seal body is performed during the entire process of the seal body moving, realizing real-time recognition of the position of the seal body, and improving the real-time performance and accuracy when the seal body moves to the outside of the stamp outlet.

[0169] In order to further enhance the detection accuracy of the position of the seal body, in this embodiment, the horizontal position of the bottom edge of the seal carrier 2 can also be provided with a positioning identifier (not shown) for the first camera device to collect. For example, the positioning identifier can choose to use vertical stripes arranged along the axial direction of the seal carrier, and the vertical stripes are, for example, stripes arranged at intervals of black and white. In this way, as long as the first camera device collects the positioning identifier image on the seal carrier, the processor can process the positioning identifier image and promptly and accurately determine the position to which the seal carrier currently moves, and then accurately monitor the seal carrier position in real time. Of course, the positioning identifier can also select other identification forms as needed, so that its image can be collected by the above-mentioned first camera device.

[0170] In order to ensure the monitoring accuracy of the stamping operation from multiple angles, the stamping monitoring mechanism of this embodiment also includes a stamp pressure detector (not shown in the figure) for detecting the pressure on the stamp body, and the stamp pressure detector is connected to the processor, which can be integrated into the controller. The stamp pressure detector is set on the stamp carrier. In this way, on the basis of the processor identifying and judging whether the stamping operation is completed based on the stamp body image captured by the first camera device, the stamp pressure detector further confirms whether the stamp body has completed a stamping operation by detecting the pressure on the stamp body.

[0171] In order to retain more abundant evidence images of the process of the stamping operation, the stamping monitoring mechanism of this embodiment further includes a second camera device 42 configured to detect the document to be stamped on the outside of the device housing, and the second camera device 42 is connected to the processor. That is to say, the image of the seal body on the inside of the device housing is captured by the first camera device, and the image of the document to be stamped on the outside of the device housing (specifically, the partial area of ​​the document to be stamped that does not extend into the stamp outlet) is captured by the second camera device, so that the relevant images of the stamping operation process can be retained, so as to facilitate the subsequent retrieval and use of these retained relevant images.

[0172] In this embodiment, an illuminating device can also be provided inside the device housing and the illuminating device is located on one side of the outer side of the seal body, so that the movable seal body will form a seal body projection area that changes in size and can be collected by the first camera device between the seal body seal pattern surface and the paper document to be stamped after the illuminating device is started. Of course, the illuminating device is preferably located in the lateral direction of the seal body central axis. In this way, as the seal body gradually moves downward and the seal body pattern surface contacts the paper document to be stamped, the area of ​​the seal body projection area collected by the first camera device will gradually change, and when the seal pattern surface contacts the paper document to be stamped, the seal body projection area will disappear, thereby judging that the seal pattern surface contacts the paper document to be stamped at this time, and a stamping operation is completed.

[0173] As another convenient way to detect the real-time position of the seal body, in this embodiment, the seal pattern surface of the seal body can also extend through the seal carrier 2 and be located at a preset distance position from the lower end surface of the seal carrier. Preferably, the preset distance position here is located 2 to 3 mm below the lower end surface of the seal carrier.

[0174] In addition, in order to occupy a small space in the device housing and drive the ink box to complete the flipping action, so as to meet the need to flip the ink box to the inner side of the device housing when the ink box is not needed, the ink box flipping mechanism of this embodiment also includes an ink box flipping mechanism. The ink box flipping mechanism includes a flipping drive shaft 93, an ink box tray 94 and a flipping track 95; the flipping drive shaft 93 is configured to cooperate with the seal carrier 2 in transmission, so that the flipping drive shaft 93 moves with the movement of the seal carrier 2 in the device housing 1; the ink box tray 94 has a tray base 940 and the ink box tray 94 has a bearing space for carrying the ink box. Among them, the tray base 940 is configured to be rotatably set to the inside of the device housing 1 and can be rotated to the bottom of the seal body pattern surface; the flipping track 95 is set on the side wall of the ink box tray 94. More specifically, the flipping track 95 is in transmission cooperation with the ink box tray 94 and is configured to cooperate with the flipping drive shaft 93 to be clamped and slide back and forth in the flipping track. Among them, the ink box tray 94 is configured to switch and adjust the ink box tray 94 between a horizontal state and a vertical state as the flip drive shaft 93 slides back and forth in the flip track 95; wherein the horizontal state is a state when the plane of the tray base and the axial direction of the device shell are perpendicular to each other, and the vertical state is a state when the plane of the tray base and the axial direction of the device shell are parallel to each other.

[0175] Specifically, in the ink box flipping mechanism of this embodiment, the flipping drive shaft 93 is configured to be set on a preset seal hanger 12 in the device housing 1, and the flip track 95 is set on the side wall of the ink box tray 94. The seal hanger 12 is configured to be able to move back and forth along the axial direction of the device housing after being driven. The seal hanger 12 here is preferably a rigid hanger, and the seal carrier 2 is hung on the seal hanger 12 with a slight upward and downward expansion space, so that the seal carrier can allow the seal body to have a larger activity space to stick to the ink in the ink box, thereby enhancing the clarity of the subsequent stamp pattern.

[0176] As a structural form of the ink cartridge tray, in this embodiment, the ink cartridge tray 94 includes a peripheral wall 941 extending upward along the edge of the periphery of the tray base 940, and the flip track 95 is arranged on the inner side wall of the peripheral wall 941; wherein the peripheral wall 941 and the tray base 940 together form the bearing space.

[0177] As a specific implementation of the flip track, in this embodiment, the flip track 95 includes a first track 951 and a second track 952 that are connected to each other. The first track 951 cooperates with the flip drive shaft 93 to be inserted and move back and forth in the first track. The first track 951 is configured to be inclined relative to the horizontal plane where the tray base 940 is located, and forms an inclination angle θ with the horizontal plane where the tray base 940 is located; the angle range of the inclination angle θ is (0°, 45°]; the second track 952 cooperates with the flip drive shaft 93 to move back and forth in the second track, and the second track 952 is configured to be parallel to the horizontal plane where the tray base 940 is located. Of course, the first track 951 and the second track 952 are both in the form of straight tracks.

[0178] In order to achieve the switching adjustment of the ink cartridge tray from the horizontal state to the vertical state in the device housing at the fastest speed and occupying the minimum space, the tilt angle θ here is preferably set to 45°.

[0179] Considering the situation that the inclination angle θ formed by the first track and the horizontal plane where the tray base is located is less than 45°, this embodiment is also specially configured that when the inclination angle θ is less than 45°, the inclination angle of the second track 952 relative to the horizontal plane where the tray base 940 is located is greater than 0° and less than 45°. In this way, when the inclination angle of the first track is less than 45°, the inclination angle of the second track relative to the horizontal plane where the tray base is located can be increased to compensate for the insufficiency of the first track in cooperating with the ink cartridge tray during the flipping process.

[0180] As a way to realize that the tray base is arranged in cooperation with the device housing, the tray base 940 is arranged on the ink cartridge hanger 97 preset inside the device housing 1 through the flip shaft 96, and the flip drive shaft 93 is configured so that when the tray base 940 is in the horizontal state, the end 93a of the flip drive shaft 93 is located at the junction 95a of the first track 951 and the second track 952, and the end 93a of the flip drive shaft 93 and the end 96a on the same side of the flip shaft 96 are both located on the first track 951. The end 952a of the second track located on the second track 952 and away from the junction is an open structure.

[0181] It is particularly important to explain that, based on the second track 952 being a straight track, the second track 952 has an upper side 9521 and a lower side 9522 that are parallel to each other and of equal length, and the lower side 9522 has a straight extension section 95221 extending along the length direction of the lower side and in a direction away from the joint 95a. By providing the straight extension section 95221 at the lower side of the second track 952, when the ink cartridge is opened and turned over to the side inside the device housing (i.e., in a vertical state), the turning drive shaft 93 on the seal hanger 12 will move vertically downward along the straight extension section 95221, thereby ensuring that the seal hanger 12 will not tilt during the downward movement.

[0182] Of course, such arrangement of the above-mentioned linear extension section 5221 can also meet the requirement that once the lower end of the inner side of the seal device shell needs to suspend one side structure of the device shell close to the camera device due to the need to set up a camera device, the linear extension section located on the other side of the device shell and arranged on the side wall of the ink box tray can be used to support and prevent the seal hanger 12 from tilting during the downward process.

[0183] As for the working method of the ink box flipping mechanism, it is as follows: when the seal hanger is driven to move toward the bottom of the device housing, the seal hanger will drive the flip drive shaft to move downward, and the flip drive shaft will slide along the flip track to realize the ink box tray flipping from a horizontal state to a vertical state; when the seal hanger is driven in the reverse direction to move toward the top of the device housing, the seal hanger drives the flip drive shaft to move upward, and the flip drive shaft will slide along the flip track to realize the ink box tray flipping from a vertical state to a horizontal state. In this way, the space required for the ink box tray to flip and switch between the horizontal state and the vertical state is exactly the height of the ink box tray, thereby achieving the effect of completing the flipping of the ink box tray by occupying a smaller space. The ink box flipping mechanism set in this way can not only meet the compact structure requirements of the seal equipment, but also complete the flipping of the ink box tray.
