[0038] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0039] References in this specification to "one embodiment" or "an example" or "an example" mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0040] In the related art, a seal is a legal symbol for an enterprise to exercise its powers, with legal authority. It is the only legal document for an enterprise to exercise its powers, handle daily official business, and conduct external exchanges. A document stamped with an enterprise's seal is a legally protected and valid document, and at the same time means that the enterprise has to bear corresponding legal responsibilities for the content of the document. Therefore, whether the seal management work of an enterprise is safe and standardized is related to the normal operation of the enterprise, and sometimes even affects the survival and development of the enterprise.

[0041] Due to the limitations of traditional physical seals themselves, it is easier to cause incidents of unauthorized use of seals, bringing huge risks and losses to enterprises. The risks of seal use are summarized as follows:

[0042] (1) The actor forges and uses the seal, damaging the interests of the enterprise;

[0043] (2) Due to the negligence of the seal keeper, the seal is stolen;

[0044] (3) Employees use the seal beyond their authority, and the validity of the contract signed with the seal is unstable, leading to disputes.

[0045] It can be seen from this that traditional physical seals need to be controlled by a strict and standardized seal use system, but the cumbersome process will also affect the seal use efficiency of enterprises. With the popularization of 5G and the Internet of Things, intelligent office equipment has been widely used in enterprise office management. It is necessary to design an intelligent hardware device to realize the seal management of enterprises.

[0046] In view of this, as Figure 1 and Figure 2 shown, an embodiment of the present invention provides a seal machine for controlling a seal to stamp, including a housing 10, an image acquisition module 20, a driving stamping module 30, and a clamping module 40 provided in the housing 10. A stamping port 100 is provided at the bottom of the housing 10, and the clamping module 40 is used to clamp the seal; characterized in that the image acquisition module 20 is provided at the top of the housing 10, and the image acquisition module 20 is used to acquire the image of the seal user and the image of the document to be stamped and send them to the server. Among them, the server is used to determine the user information of the seal user based on the image of the seal user, and determine the document information of the document to be stamped based on the image of the document to be stamped, match the user information with the document information, and send a stamping instruction to the driving stamping module 30 in the case of successful matching;

[0047] The driving stamping module 30 can limit the clamping module 40 in a releasable manner. Among them, when the clamping module 40 receives the stamping instruction, the clamping module 40 is allowed to move from a preset position to the stamping port 100 for stamping, or move from the stamping port 100 to the preset position. The preset position is located between the image acquisition module 20 and the stamping port 100.

[0048] The driving stamping module 30 provided by the present invention is used to drive the clamping module 40 to reciprocate between the stamping port 100 and the preset position for stamping or retracting the stamp, ensuring the safety of using the stamp. The image acquisition module can acquire images of the document to be stamped and the person using the stamp, completing the management work of the content of the stamped document by the management personnel and minimizing the risk of using the stamp in the enterprise.

[0049] In some embodiments, the image acquisition module 20 includes a first image acquisition unit and a second image acquisition unit. The first image acquisition unit is used to capture an image of the person using the stamp and send it to the server, and the second image acquisition unit is used to capture an image of the document to be stamped and send it to the server; among them, the image of the person using the stamp is captured synchronously with the image of the document to be stamped. When it is necessary to trace the processing process of the document, the synchronously captured content can provide a clear operation record. Whether it is an internal audit or an external supervision and inspection, by viewing the captured materials, the corresponding relationship between the stamped document and the person using the stamp can be quickly and accurately understood to confirm whether it meets the relevant standards of the enterprise.

[0050] In some embodiments, the housing 10 forms a first chamber and a second chamber. The first chamber is located at the top of the second chamber, and the stamping port 100 is provided at the bottom of the second chamber;

The abnormal timeout module is configured to control the operation of the servo motor according to the position detection result of the position detection module.

[0059] In some embodiments, the clamping module 40 includes a cylinder body 410 and a clamping ring 420 sleeved outside the cylinder body 410. The cylinder body 410 is disposed along the height direction of the housing 100. The cylinder body 410 forms a chamber 40 for clamping a seal. A plurality of clamping plates 430 and a plurality of connecting plates 440 are disposed around the bottom periphery of the chamber. The top ends of the clamping plates and the connecting plates are flexibly connected to the bottom of the chamber, and the bottom ends of the clamping plates and the connecting plates are free ends. External threads are provided on the outer sides of the connecting plates, and internal threads matching the external threads are provided on the inner side of the clamping ring 420. An inclined surface matching the inner wall of the clamping ring 420 is provided on the outer side of the clamping plate. As the clamping ring 420 rotates, the clamping ring 420 moves downward, and the inner wall of the pressing ring 420 contacts the inclined surface to push the clamping plate to contract towards the inside of the cylinder body 410. The connecting plate can contract towards the inside of the cylinder body 410 so that the clamping ring 420 is disengaged from the connecting plate.

[0060] In some embodiments, a seal cover 60 is movably disposed at the stamping opening 100. The seal cover is configured to open or close the stamping opening 100. The seal cover in the open state can avoid the movement path of the clamping module 40.

[0061] A mating post is provided at the bottom end of the cylinder body 410 of the clamping module 40, and a mating groove 61 matching the mating post is provided on the seal cover. When the clamping module 40 moves towards the stamping opening 100, the mating post is inserted into the mating groove and pushes the seal cover to open the stamping opening 100. When the clamping module 40 moves from the stamping opening 100 to the preset position, the mating post is inserted into the mating groove and pulls the seal cover to close the stamping opening 100.

[0062] In some embodiments, an ink cartridge mounting bracket 8 is provided on the side of the seal cover facing the inside of the housing 10. The seal cover includes mounting side plates clamped on both sides of the ink cartridge mounting bracket and a hinge seat hinged to the stamping opening 100. Slide rails 91 penetrating along the length direction of the mounting side plates are provided on the opposite sides of the two mounting side plates, and a limiting track 92 is provided at the bottom of the slide rails 91.

[0063] On both sides of the cartridge mounting bracket 8, there are first spring ejector pins 81 corresponding to the limit track 92 and mounting posts 82 corresponding to the slide rail 91. At the end of the limit track 92, there is a first spring ejector pin mounting hole 93. At one end of the cartridge mounting bracket 8 facing the hinge seat, there is a second spring ejector pin 83, and the hinge seat is provided with a second spring ejector pin mounting hole corresponding to the second spring ejector pin.

[0064] A receiving space for accommodating the cartridge 7 is formed inside the cartridge mounting bracket. The cartridge is symmetrically provided with rotating shafts 71, and the cartridge mounting bracket is provided with rotating holes 84 corresponding to the rotating shafts 71. The cartridge 7 is rotatably arranged in the receiving space. At the upper end of the rotating hole 84, there is a mounting notch facilitating the installation of the rotating shaft 71, and a clamping protrusion 840 is also provided at the mounting notch.

[0065] The limit track is a side-inclined track. The limit track gradually protrudes inward from the opening. At the inner end of the limit track, there is a curved track communicating with the slide rail, and the curved track forms the first spring ejector pin mounting hole. The upper side of the curved track is directly communicated with the slide rail. The first spring ejector pin moves from the opening position of the limit track into the curved track. At this time, because the limit track is an inclined track, the protrusion of the limit track makes the first spring ejector pin unable to enter the limit track again, and at this time, the first spring ejector pin is fixed in the curved track.

[0066] When it is necessary to take out the rotating bracket from the seal cover, lift the cartridge mounting bracket so that the first spring ejector pin slides out from the upper side of the curved track and directly enters the slide rail, and is taken out from the opening of the slide rail. At this time, the rotating bracket can be taken out from the seal cover.

[0067] When the seal cover is opened or closed, when the seal cover is not closed in place, at this time, the ink pad sponge in the cartridge and the seal do not make full contact over the entire surface, and the integrity of the stamping cannot be guaranteed. Through the design of the rotating cartridge solution, the cartridge can deflect on the cartridge mounting bracket, and the part that the cartridge first contacts is pushed by the seal, so that the cartridge rotates, so as to realize the full contact between the ink pad sponge and the seal, and can effectively adjust the full contact between the cartridge and the sponge in the above situation.

[0068] The present invention can realize the remote supervision of enterprise seals, and effectively solve the problems of cumbersome processes and low seal usage efficiency brought by the strictly controlled seal system.

[0069] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
