Seal monitoring mechanism, seal equipment and seal method

Abstract

The invention relates to a seal monitoring mechanism, seal equipment and a seal method. The seal monitoring mechanism comprises a first camera module used for collecting surface images of a to-be-sealed file located on the outer side of the seal equipment shell, a second camera module used for collecting surface images of a file located on the to-be-sealed file and located on the inner side of the seal equipment shell, and a controller connected with the first camera module and the second camera module. The controller processes and judges whether the files corresponding to the surface images of the to-be-sealed files collected by the camera modules belong to the same continuous file or not; and once it is judged that the files belong to the same continuous file, it is judged that no shooting blind area exists on the files to be stamped, otherwise, it is judged that the files to be stamped are abnormal or shooting monitoring is abnormal, and therefore non-blind-area monitoring of the stamp monitoring mechanism on the files stamped by the stamp equipment is achieved.

Description

Technical Field

[0001] The present invention relates to the field of seal equipment, and in particular to a seal monitoring mechanism, a seal equipment and a seal method. Background Art

[0002] Existing smart seal devices usually include a seal device housing, a seal body, a camera device, a driving mechanism for driving the seal body to move, and a controller for controlling the driving mechanism and the camera device, wherein the camera device is arranged above the outer side of the seal device housing. When the smart seal device performs a seal action, the driving mechanism is controlled by its controller so that the driving mechanism drives the seal body in the seal device housing to the outer side of the seal device housing, so as to perform a stamping operation on the document content outside the seal device housing, and the camera device takes a picture of the content on the document to be stamped.

[0003] However, existing smart seal devices have shortcomings: the camera device cannot capture the key content of the document that is located on the document and covered by the seal body, resulting in a blind spot for the content of the document to be stamped, causing the risk of the seal being stamped on an unauthorized document. In addition, the camera device also has the risk of being moved or blocked, which in turn causes the risk of the seal being stamped on an unauthorized document. Summary of the invention

[0067] The present invention is further described in detail below with reference to the accompanying drawings.

[0068] This embodiment provides a seal monitoring mechanism that does not have a blind spot in the image capture of the document to be stamped. Figures 1 to 4As shown, the seal monitoring mechanism of this embodiment includes a first camera module, a second camera module and a controller, and the controller is connected to the first camera module and the second camera module respectively. The first camera module collects the surface image of the document to be stamped located outside the seal device housing 1, and the second camera module collects the surface image of the document located on the document to be stamped and inside the seal device housing 1.

[0069] When the seal monitoring mechanism of this embodiment performs seal monitoring on the document to be stamped, the first camera module sends the surface image of the document to be stamped on the outside of the seal device housing and the surface image of the document to be stamped on the inside of the seal device housing collected by the second camera module to the controller, and then the controller processes all the collected surface images of the document to be stamped to determine whether the file corresponding to the file surface image collected by the first camera module and the file corresponding to the file surface image collected by the second camera module belong to the same continuous file. Once it is determined that they belong to the same continuous file, it means that the file surface on which the seal device currently performs the stamping operation is the same file as the file surface on the outside of the seal device housing, and there is no risk that the file contents inside and outside the seal device housing do not belong to the same file; otherwise, it means that the file surface on which the seal device currently performs the stamping operation is not the same file as the file surface on the outside of the seal device housing, and there is a risk that the file contents inside and outside the seal device housing do not belong to the same file. In this way, the seal monitoring mechanism realizes the blind spot monitoring of the document stamped by the seal device.

[0070] Specifically, in this embodiment, a light-transmitting area 100 is provided at the bottom of the side wall of the seal device housing; the above-mentioned second camera module is configured to collect the surface image of the document to be stamped located on the inner side of the seal device housing 1 and the surface image of the document to be stamped passing through the light-transmitting area 100 and connecting the inner and outer areas of the seal device housing 1. As a setting method of the above-mentioned light-transmitting area 100, the light-transmitting area 100 here is a physical opening formed at the bottom of the side wall of the seal device housing 1, and the physical opening is connected to the inner side of the seal device housing. Of course, according to needs, the light-transmitting area 100 here can also be a transparent area set on the bottom of the side wall of the seal device housing 1. Among them, the light-transmitting area 100 in this embodiment adopts the above-mentioned setting method of forming a physical opening on the side wall of the seal device housing.

[0071] Considering the actual situation that the seal device performs a stamping operation on the document to be stamped, in this embodiment, the surface image of the document to be stamped collected by the first camera module and the surface image of the document to be stamped collected by the second camera module have an overlapping area or a coincident area; wherein the coincident area is a coincident line or a coincident surface. That is to say, the surface images of the document to be stamped collected by the two camera modules can be overlapped on the document surface area, or the surface image of the document to be stamped collected by one camera module and the surface image of the document to be stamped collected by another camera module can be spliced ​​together along the same line.

[0072] Considering that the seal device housing itself has a certain thickness (i.e., the thickness between the outer wall and the inner wall of the seal device housing), when stamping, the seal device housing itself will press on the document to be stamped. Therefore, in order to monitor the surface of the document pressed by the seal device housing and to more accurately monitor the stamped document without blind spots, this embodiment provides three implementation methods of the seal monitoring mechanism. Specifically:

[0073] As a first improved implementation of the seal monitoring mechanism, the first camera module of this embodiment includes a first camera device c1 connected to a controller, and the first camera device c1 is arranged on the top of the outer side of the seal device housing 1; the second camera module includes a second camera device c2 connected to the controller, and the second camera device c2 is arranged on the top of the inner side of the seal device housing 1; wherein:

[0074] The first camera device c1 is configured to capture the surface image of the document to be stamped located outside the stamp device housing 1, or / and the first camera device c1 is configured to capture the surface image of the document to be stamped passing through the light-transmitting area 100 and connecting the inner and outer areas of the stamp device housing 1;

[0075] The second camera device c2 is configured to capture the surface image of the document to be stamped located on the inner side of the seal device housing 1, or / and the second camera device c2 is configured to capture the surface image of the document to be stamped that passes through the light-transmitting area 100 and connects the inner and outer areas of the seal device housing 1; and the surface image of the document to be stamped captured by the first camera device c1 and the surface image of the document to be stamped captured by the second camera device c2 have the above-mentioned overlapping area or coincident area.

[0076] Considering that the seal device housing itself has a certain thickness (i.e., the thickness between the outer wall and the inner wall of the seal device housing), when stamping, the seal device housing itself will be pressed on the document to be stamped. Therefore, in order to monitor the surface of the document pressed by the seal device housing, so as to more accurately monitor the stamped document without blind spots, the second camera device c2 here can also be further configured to collect the surface image of the document to be stamped located on the inner side of the seal device housing 1 and collect the surface image of the document to be stamped on the inner and outer areas of the seal device housing 1 through the light-transmitting area 100. In this case, the second camera device c2 is arranged on a corner of the top of the inner side of the seal device housing 1.

[0077] As a second improved implementation method of the seal monitoring mechanism, in this embodiment, the first camera module includes a first camera device c1 connected to the controller, and the first camera device c1 is arranged at the top of the outer side of the seal device housing 1; the second camera module also includes a third camera device c3 connected to the controller, and the third camera device c3 is arranged on the inner side of the seal device housing 1 and at the bottom of the side wall of the seal device housing 1; wherein the third camera device c3 is configured to capture the surface image of the document to be stamped located on the inner side of the seal device housing 1, or / and the third camera device c3 is configured to capture the surface image of the document to be stamped through the light-transmitting area 100 and connecting the inner and outer areas of the seal device housing 1. Among them, the first camera device c1 is configured to capture the surface image of the document to be stamped located on the outside of the seal device housing 1, or / and the first camera device c1 is configured to capture the surface image of the document to be stamped on the inner and outer areas of the seal device housing 1 through the light-transmitting area 100; and the surface image of the document to be stamped captured by the first camera device c1 and the surface image of the document to be stamped captured by the second camera device c2 have overlapping areas or coincident areas; or / and, the surface image of the document to be stamped captured by the first camera device c1 and the surface image of the document to be stamped captured by the third camera device c3 have overlapping areas or coincident areas.

[0078] The second camera device c2 and the third camera device c3 may also have the following functions: collecting the surface image of the document to be stamped located inside the seal device housing 1 and collecting the surface image of the document to be stamped passing through the light-transmitting area 100 and connecting the inside and outside areas of the seal device housing 1. That is, the surface image of the document to be stamped passing through the light-transmitting area 100 and connecting the inside and outside areas of the seal device housing 1 is taken by the camera device at an angle. The third camera device c3 is preferably arranged opposite to the light-transmitting area 100. In this way, when the seal monitoring mechanism performs seal monitoring on the document to be stamped, the first camera device c1 sends the surface image of the document to be stamped, the surface image of the document to be stamped, the surface image of the document to be stamped, the surface image of the document to be stamped, the surface image of the document to be stamped, and the surface image of the document to be stamped collected by the second camera device c2 and the surface image of the document to be stamped collected by the third camera device c3 to the controller, and the controller processes all the collected surface images of the document to be stamped to determine whether the file corresponding to the file surface image collected by the first camera device, the file corresponding to the file surface image collected by the second camera module, and the file corresponding to the file surface image collected by the third camera device belong to the same continuous file. Once it is determined to belong to the same continuous file, it means that the file surface on which the seal device is currently performing the stamping operation is the same file as the file surface on the outside of the seal device housing, and there is no risk that the file contents inside and outside the seal device housing do not belong to the same file; otherwise, it means that the file surface on which the seal device is currently performing the stamping operation is not the same file as the file surface on the outside of the seal device housing, and there is a risk that the file contents inside and outside the seal device housing do not belong to the same file. In this way, by collecting and judging the multi-region images of the stamped document, it is possible to more accurately monitor the stamped document without blind spots.

[0079] As a third improved implementation of the seal monitoring mechanism, in this embodiment, the first camera module includes a first camera device c1 connected to the controller, and the first camera device c1 is arranged on the top of the outer side of the seal device housing 1; the second camera module includes a third camera device c3 connected to the controller, and the third camera device c3 is arranged on the inner side of the seal device housing 1 and at the bottom of the side wall of the seal device housing 1; wherein:

[0080] The first camera device c1 is configured to capture the surface image of the document to be stamped located outside the stamp device housing 1, or / and the first camera device c1 is configured to capture the surface image of the document to be stamped passing through the light-transmitting area 100 and connecting the inner and outer areas of the stamp device housing 1;

[0081] The third camera device c3 is configured to collect the surface image of the document to be stamped located inside the seal device housing 1 and collect the surface image of the document to be stamped passing through the light-transmitting area 100 and connecting the inside and outside areas of the seal device housing 1. Among them, the surface image of the document to be stamped collected by the first camera device c1 and the surface image of the document to be stamped collected by the third camera device c3 have overlapping areas or coincident areas. Here, the third camera device c3 takes oblique shots of the inside area surrounded by the outer wall of the seal device housing, and the third camera device c3 is preferably arranged opposite to the light-transmitting area 100. In this way, when the seal monitoring mechanism performs seal monitoring on the document to be stamped, the first camera device c1 sends the surface image of the document to be stamped collected by it and the surface image of the document to be stamped collected by the third camera device c3 to the controller, and the controller processes all the collected surface images of the document to be stamped to determine whether the file corresponding to the file surface image collected by the first camera device and the file corresponding to the file surface image collected by the third camera device are continuous files. Once it is determined to be a continuous file, it means that the file surface on which the seal device is currently performing the stamping operation is the same as the file surface on the outside of the seal device shell, and there is no risk that the file contents inside and outside the seal device shell do not belong to the same file; otherwise, it means that the file surface on which the seal device is currently performing the stamping operation is not the same as the file surface on the outside of the seal device shell, and there is a risk that the file contents inside and outside the seal device shell do not belong to the same file. In this way, by collecting and judging multi-region images of the file to be stamped, it is possible to more accurately monitor the stamped file without blind spots.

[0082] Of course, according to actual needs, the seal monitoring mechanism of this embodiment also includes a lighting device configured to be set inside the seal device housing, and the lighting device is connected to the controller. In this way, when the second camera device or / and the third camera device start the acquisition work, the controller can control the lighting device to work, so as to collect the surface image of the corresponding file under the lighting condition.

[0083] This embodiment provides a seal device. Specifically, the seal device includes a seal device housing 1 and a seal body 3, and the seal device is applied with the seal monitoring mechanism of the first improved implementation method. Among them, the seal device applied with the seal monitoring mechanism of the first improved implementation method is referred to as the first seal device in this embodiment.

[0084] In this embodiment, for the seal device using the seal monitoring mechanism of the first improved implementation mode, the seal device has a first improved driving mechanism for driving the seal body to turn upside down.

[0085] Specifically, see Figures 5 to 13As shown, the seal device of this embodiment also includes a seal body device 2 and a first improved driving mechanism, and the first improved driving mechanism includes a driving mechanism and a guide rail structure; the seal device housing 1 has a seal outlet 10 located below it, the seal body device 2 is movably arranged inside the seal device housing 1, and the seal body device 2 is provided with the above-mentioned seal body 3, the seal body 3 has a seal pattern surface 31, and the upper part of the seal body device 2 has a seal pattern surface 31 facing the inner side of the seal device housing 1 in an initial state; the driving mechanism is configured to drive the seal body device 2 to move inside the seal device housing 1; the guide rail structure is located inside the seal device housing 1 and cooperates with the seal body device 2, so that the seal body device 2 driven by the driving mechanism moves along the guide rail direction of the guide rail structure to complete the up, down, left and right movement of the seal body device; wherein, the guide rail structure has a flexible positioning structure 7 configured to resist the moving seal body device in a flexible manner to realize the up and down flipping of the seal body device. As needed, the driving mechanism can be electrically driven or manually driven. Of course, in this embodiment, the driving mechanism is manually driven.

[0086] In the seal device of this embodiment, a flexible positioning structure that can flexibly resist the seal body device is provided on the guide rail structure, so that the seal body device driven by the driving mechanism moves along the guide rail direction of the guide rail structure and then resists the flexible positioning structure to complete the up and down flipping of the seal body device. The guide rail structure can complete the up, down, left and right movement of the seal body device with a smaller guide rail length, avoiding the guide rail structure from occupying a larger space. Moreover, because the flexible positioning structure flexibly resists the moving seal body device, the up and down flipping action of the seal body device can be ensured to be more stable and reliable.

[0087] Specifically, in this embodiment, see Figure 6 and Figure 7 As shown, the seal body device 2 includes an outer shell 20 and a seal body 3 located inside the outer shell 20, the seal body 3 has the seal pattern surface 31 located outside the outer shell 20, the outer shell 20 is formed with a first shaft body 21 and a second shaft body 22 located outside thereof, the first shaft body 21 is located above the second shaft body 22, the guide rail structure includes a first guide rail 41 and a second guide rail 42, the first guide rail 41 is arranged along the first preset curve direction, the second guide rail 42 is arranged along the second preset curve direction and cooperates with the first guide rail 41, and the above-mentioned flexible positioning structure is arranged on the second guide rail 42. The first shaft body 21 of the outer shell 20 is inserted into the first guide rail 41 to slide back and forth along the first guide rail, the second shaft body 22 of the outer shell 20 is inserted into the second guide rail 42 to slide back and forth along the second guide rail, and the second shaft body 22 slides in the second guide rail 42 and can resist the flexible positioning structure 7.

[0088] As required, the flexible positioning structure here can be a component independent of the second guide rail 42, or can be formed by the second guide rail 42. In this embodiment, the flexible positioning structure 7 is an independent elastic component, such as an elastic columnar structure.

[0089] It should be noted that, on the outer shell 20 of this embodiment, the second shaft 22 is preferably arranged in the middle position of the outer shell 20, so that the entire seal body device can complete its own up and down and left and right movement by moving a shorter track stroke, thereby saving space in the seal device shell for the seal body device to flip up and down. It can be understood that since the second shaft is arranged in the middle position of the outer shell of the seal body device, the stroke of the entire seal body device when flipping around the second shaft is obviously smaller than the stroke of the entire seal body device when the second shaft is in other positions.

[0090] As for the specific structural form of the guide rail structure, see Figures 6 to 9 As shown, in this embodiment:

[0091] The first preset curve direction includes a first inclined section 411, a first connecting section 412 and a first vertical section 413 arranged from top to bottom, and the first connecting section 412 connects the first inclined section 411 and the first vertical section 413 respectively;

[0092] The second preset curve includes a second inclined section 421, a second connecting section 422 and a second vertical section 423 arranged from top to bottom. The second connecting section 422 connects the second inclined section 421 and the second vertical section 423 respectively. The above-mentioned flexible positioning structure 7 is arranged at the connection between the second vertical section 423 and the second connecting section 422.

[0093] Since the flexible positioning structure is an independent elastic component, the flexible positioning structure 7 can be embedded in a position close to the second guide rail 42 , and one end of the flexible positioning structure 7 is located in the second guide rail 42 so that the sliding second shaft 22 can resist it.

[0094] It should be noted that in the above-mentioned first preset curve and the second preset curve, each inclined section and each connecting section is preferably a curved curve, and combined with the flexible positioning structure provided on the second guide rail, it can ensure that the seal body device can move up, down, left and right more stably.

[0095] As a setting mode of the guide rail structure, the stamp device further includes a track plate 5 arranged inside the stamp device housing 1, and a vertical guide rail 50 is arranged on the track plate 5 to cooperate with the driving member 82 to move back and forth in the up and down directions, and the guide rail structure is arranged on the track plate 5. Of course, a cover plate 51 can also be provided to cover the second guide rail 42 on the track plate 5.

[0096] In order to make the seal body device move laterally more stably and smoothly in the seal device housing, the seal device of this embodiment further includes a first damping member 61 that is damped with the first shaft 21 of the seal body device 2. For example, the first damping member 61 here is a bearing.

[0097] In order to make the seal body device 2 move laterally more stably in the seal device housing, the seal device of this embodiment further includes a second damping member 62 that cooperates with the second shaft 22 of the seal body device 2 for damping.

[0098] In this embodiment, since the driving mechanism adopts manual drive, as the implementation method of the driving mechanism, the driving mechanism of this embodiment includes a pressing member 81 located on the outside of the seal device housing 1 and a driving member 82 located on the inside of the seal device housing 1. The pressing member 81 is responsible for bearing the manual pressing force applied by the outside, and the pressing member 81 can be slidably arranged on the seal device housing 1 in the up and down direction; the driving member 82 is transmission-connected with the pressing member 81 so as to slide back and forth in the up and down direction under the drive of the pressing member 81, and the driving member 82 is transmission-coordinatedly connected with the seal body device 2 to drive the seal body device 2 to move vertically in the up and down direction with the driving member 82, and the driving member 82 is provided with a transverse guide rail 820 that cooperates with the seal body device 2 to make transverse movement in the seal device housing 1; the above-mentioned guide rail structure is located on the inside of the seal device housing 1 and cooperates with the seal body device 2 to make the seal body device 2 driven by the driving member 82 move along the guide rail direction of the guide rail structure to complete the up, down, left and right movement of the seal body device. The pressing member 81 and the driving member 82 are connected by snapping.

[0099] In this way, by setting the driving mechanism of the above-mentioned manual drive mode, after the user applies manual pressing force to the pressing piece of the seal device, the pressing piece makes a sliding movement in the up and down directions on the seal device housing, and then the pressing piece drives the driving piece to move downward, and the moving driving piece drives the seal body device to move laterally along the transverse guide rail of the driving piece in the seal device housing, and the seal body device also moves along the guide rail direction defined by the guide rail structure while moving laterally, until the second axis of the seal body device hits the flexible positioning structure in the second guide rail during the movement, so that the seal body device is turned upside down after being subjected to the flexible resistance of the flexible positioning structure, and the seal pattern surface of the seal body faces the outside of the seal outlet and moves to the outside of the seal outlet, thereby completing the subsequent stamping operation; when stamping is not required, a reverse force is applied to the pressing piece to make the pressing piece move in the reverse direction, thereby causing the seal body to perform a reverse action.

[0100] Specifically, in this embodiment, the first shaft 21 of the outer shell 20 passes through the first guide rail 41 and is inserted into the transverse guide rail 820 of the driving member 82 to slide back and forth along the transverse guide rail, and the second shaft 22 of the outer shell 20 is inserted into the second guide rail 42 to slide back and forth along the second guide rail. Here, by allowing the first shaft 21 of the outer shell 20 to pass through the first guide rail 41 and be inserted into the transverse guide rail 820 of the driving member 82, the transmission connection between the driving member and the seal body device is achieved.

[0101] In order to cooperate with the pressing member to slide back and forth stably along the vertical direction on the stamp device housing, the stamp device housing 1 is provided with a vertical slide rail 11 that cooperates with the pressing member 81 to slide back and forth along the vertical direction. The vertical slide rail 11 is preferably arranged on the outer side wall of the stamp device housing 1.

[0102] Specifically, the pressing member 81 includes a pressing member body 811 and a connecting member 812. The pressing member body 811 is located outside the stamp device housing 1 and has a sliding portion 8111 that cooperates with the vertical slide rail 11. The connecting member 812 is disposed on the pressing member body 811 and is transmission-connected with the driving member 82 after passing through the stamp device housing 1. For example, the sliding portion 8111 is a vertical ridge formed on the inner wall of the pressing member body, and the vertical ridge is slidably matched with the vertical slide rail on the stamp device housing.

[0103] In order to facilitate the user to manually operate the pressing member so that the pressing member slides up and down along the stamp device housing, a force-bearing portion 811a for manual gripping is provided on the pressing member body 811. The force-bearing portion 811a is a fan-shaped plate formed on the pressing member body 811 and extending toward the outside of the pressing member body, and the arc edge of the fan-shaped plate is located away from the pressing member body.

[0104] This embodiment also provides a second seal device. Specifically, the seal device includes a seal device housing 1 and a seal body 3, and the seal device is applied with the seal monitoring mechanism of the second improved implementation method. Of course, the seal device here also adopts the first improved driving mechanism that drives the seal body to move up, down, left, and right. The setting method of the first improved driving mechanism is the same as that of the seal device that applies the seal monitoring mechanism of the first improved implementation method, and will not be repeated here.
