As shown in fig. 1 and 2, an embodiment of the present invention provides an intelligent stamp, including: seal body 1, base body 2, authentication device and processor. Wherein, seal body 1 includes: a microtube array constituted by a plurality of microtubes 11, the base body 2 comprising: an ink chamber 21 containing ink. When the authentication of the authentication device is passed, the processor controls a first part of the microtubes in the microtube array to suck ink from the ink cavity to form a target pattern; when the authentication of the authentication device is failed, the processor controls a second part of the microtubes in the microtube array to suck ink from the ink cavity to form an alarm pattern, such as illegal print, authorization failure and the like, or controls all the microtubes in the microtube array to suck ink or not to suck ink.

The micro-pipe 11 forms a pattern and a character according to the difference of density, and the pattern and the character can be distributed and set through a narrow-band NB, 2G, 4G, 5G and other wireless networks. Therefore, the risk of cracking the seal content according to the analysis of the ink consumption of the array seal can be avoided by the separated design of the array microtube and the ink cavity. Furthermore, the authentication is carried out through the authentication device, a legal target pattern can be formed only when the authentication is passed, and a pattern or an alarm pattern cannot be formed when the authentication is not passed, so that brute force cracking can be prevented, the seal cannot be illegally used even if the seal is physically damaged, and the safety of the seal is improved.

Further, when the stamp body 1 is placed on the base body 2, the processor controls all the micro tubes in the micro tube array to absorb ink or not to absorb ink. That is, when the stamp and the base are placed together, the micro tube 11 of the stamp is tightly combined with the ink chamber 21 below, and compared with the external air pressure, a closed pipeline is formed, and the residual ink in the micro tube 11 is sucked back into the ink chamber 21 of the base body 2 for the next use.

As shown in fig. 1 to 4, the stamp body 11 further includes: a switch 12 controlling the microtubes 11, and a first controller 13 controlling the switch 12, wherein each microtube 11 in the microtube array is provided with a separate switch 12. That is, the stamp face of the stamp is composed of a series of capillary tubes 11 with controllable switches 12, each switch 12 being individually controllable. The base body 2 further includes: the ink supply device comprises a sleeve 22 matched with the micro-tube 11 and a second controller 23 for controlling the ink cavity 21, wherein one sleeve 22 is sleeved with one micro-tube 11, an ink inlet of the sleeve 22 is communicated with the ink cavity 21, that is, the capillary micro-tube 11 is contacted with the ink cavity 21 (an oil supply cavity) of the lower base body 1, and the oil supply cavity and the capillary micro-tube form oil supply grooves which correspond to each other one by one. The first controller 13 and the second controller 23 are respectively connected with the authentication processor, when the authentication of the authentication device passes, the processor outputs a first signal to the first controller 13 and the second controller 23, and the switch 12 controls the first part of the micro-tubes to suck ink from the ink cavity 21 under the action of the first signal to form a target pattern; when the authentication of the authentication device is not passed, the processor outputs a second signal to the first controller 13 and the second controller 23, the switch 12 controls the ink absorption of the second part of the micro-tubes from the ink cavity 21 to form an alarm pattern under the action of the second signal, or the switch 12 controls all the micro-tubes 11 to absorb ink or not to absorb ink under the action of the second signal.

That is to say, the ink cavity 21 of the seal body 1 and the base body 2 is designed separately, each micro tube 11 of the seal body 1 and the sleeve 22 array of the base body 2 jointly form a closed cavity, and the micro tubes 11 of the seal body 1 and the sleeve 22 array of the base body 2 cooperate with positive pressure and negative pressure, so that when the seal is not used, the micro tubes 11 of the seal body 1 cannot suck ink, and the seal content cannot be cracked by the ink consumption of each ink outlet unit.

As shown in fig. 3 and 4, the first controller 13 includes a first air pump, and the stamp body 1 further includes: a first variable pressure air chamber 14 controlled by a first air pump, a micro tube 11 communicated with the first variable pressure air chamber 14, and a switch 12 disposed in the first variable pressure air chamber 14. That is, the upper end of the capillary tube 11 of the stamp body 1 is communicated with the first variable pressure air chamber 14, and the first variable pressure air chamber 14 is dynamically controlled by a first air pump (controllable air pump).

Correspondingly, the second controller 23 includes a second air pump, and the base body 2 further includes: a second variable pressure air chamber 24 controlled by a second air pump, and the ink chamber 21 is formed of a flexible container and is disposed in the second variable pressure air chamber 24. That is, the ink in the ink chamber 21 (oil supply tank) is contained in a flexible container placed in the second variable-pressure air chamber 24, and the second variable-pressure air chamber 24 is dynamically controlled by a second air pump (controllable air pump).

Wherein, the bottom of the seal body 1 is densely provided with capillary micro-tubes 11, and the upper parts of the micro-tubes 11 are controlled to be opened and closed by an electric control switch 12. The first variable pressure air chamber 14 at the top is controlled by a first air pump to perform positive pressure and negative pressure control, and is used for being matched with the base body 2 to suck and release ink. The base body 2 comprises base sleeves 22 which are densely arranged and correspond to the capillary microtubes 11 of the stamp body 1 one to one, and the sleeves 22 are combined with the capillary microtubes 11 one to form a closed cavity when the stamp body 1 is placed into the base body 2. These sleeves 22 are communicated with the internal ink chamber 21, and the position and the amount of ink entering the capillary micro tube 11 are controlled by the positive pressure of the first variable pressure air chamber 14 of the stamp body 1, the negative pressure of the second variable pressure air chamber 24 of the base body 2, and the capillary micro tube 11 according to the control of the preset switch 12, so as to form the designated characters or patterns.

When the stamp body 1 and the base body 2 are placed together, the capillary microtubes 11 of the stamp body 1 are tightly combined with the oil supply groove sleeves 22 corresponding to the lower ink cavities 21, an airtight pipeline is formed by comparing external air pressure, and under the combined action of the first air pump of the stamp body 1 and the second air pump of the base body 1, the tight cavities combined in one-to-one correspondence are matched, so that the amount of ink entering the stamp capillary microtubes can be accurately controlled. Because each capillary micro-tube 11 of the stamp body 1 is controlled by the independent switch 12, the ink entering the capillary micro-tube 11 can selectively enter to control the characters or patterns finally output by the stamp.

Optionally, the stamp body further includes: and the pressure sensor controls the ink absorption in the ink cavity of the first part of the microtubes in the microtubes array by the processor to form a target pattern if the pressure sensor detects the printing operation when the authentication of the authentication device is passed. For example, when the stamp is taken, the stamp-pad ink is kept in the micro-tube array by virtue of capillary action, and when the stamp-using operation is sensed by the pressure sensor, the MCU/CPU controls the switch 12 above the capillary micro-tube 11 to be opened, optionally through positive pressure of an internal air cavity, the ink is controlled to be pushed out, and the stamp-using operation is completed. Different patterns or characters can be led out according to a certain sequence according to configuration through sensing of the pressure sensor and counting of the MCU/CPU, and the effect that one seal can print a plurality of characters and patterns is achieved.

Optionally, the authentication device includes: at least one of a face recognition module, a fingerprint recognition module, a password module and a remote authorization module. The seal taking person is authenticated and identified through modes of face identification, fingerprint identification, remote authorization and the like, if the seal taking person passes the authorization, capillary micro-tubes in the shape of the designated area of the seal body 1 are opened, capillary micro-tubes in other areas are closed, and the designated amount of ink is pushed into the seal capillary micro-tubes in the designated area and shape by matching the positive pressure of the second variable pressure air cavity 24 of the base body 2 and the negative pressure of the first variable pressure air cavity 14 of the seal body 1. Then, the pressure sensor 15 detects that when the stamping operation is executed, the negative pressure of the first variable pressure air cavity 14 is released, and the ink falls down to form a correct stamp pattern. When the seal body 1 is put back to the base body 2, the seal body 1 is matched with the closed cavity, positive pressure is formed on the seal body 1, negative pressure is formed on the base body 2, and residual ink is sucked into the ink cavity 21 of the base body 2 to be prepared for next use. If the authorization is not passed, the operation of pushing the ink in the base body 1 into the stamp capillary tube is optionally prohibited. Or, the ink in the optional designated area enters the seal micropipe through the process to form characters such as 'illegal use printing', 'authorization failure' and the like, and the characters are reserved as evidence of illegal use printing.

Optionally, the intelligent stamp further comprises: and the alarm module reports an alarm signal through the alarm module when the authentication of the authentication device is not passed. That is, when the authorization is not passed, the operation of pushing the ink in the base body 1 into the stamp capillary tube is optionally prohibited. Or, the ink in the optional designated area enters the seal micropipe through the process to form characters such as 'illegal use of seal', 'authorization failure' and the like, the characters are reserved as evidence of illegal use, and meanwhile, the alarm is reported through a wireless network such as NB (NB). For example, the base body 2 and the stamp body 1 further include a wireless communication module including an MCU, a FLASH, a power module, an NB/2G/4G/5G, an antenna, a pressure sensor, etc., and perform linkage control on the capillary micro-tube and the pneumatic chamber, and configure the capillary micro-tube and the cloud system to issue data interaction and upload a use state.

Optionally, the positive pressure of the first variable pressure air chamber 14 is matched with the negative pressure of the second variable pressure air chamber 24, and the switching duty ratio of the micro tube 11 is independently controlled and the pressure sensor 15 is matched, so that the effect that a plurality of patterns and characters can be printed on one stamp is achieved.

Optionally, the intelligent stamp further comprises: and the memory stores the corresponding relation between the authentication data and the target patterns, wherein different authentication data correspond to respective target patterns. The seal is matched with local authentication, cloud authorization and data interaction, digital management of the seal is achieved, one seal can be used by multiple people, and different seal contents are output according to different authorities.

Optionally, as shown in fig. 4 and 5, the stamp body 1 further includes: the micro-tube ink-jet printer comprises a guide sheet 16 arranged around the micro-tube 11 and a stepping motor 17 connected with the guide sheet 16, wherein the stepping motor 17 drives the guide sheet 16 to change the ink outlet angle of the micro-tube 11 under the control of the processor. Through the cooperation of the guide piece 16, the direction of the ink flowing down from the seal micropipe 11 is finely controlled, and the fine effect of patterns and characters is further improved. By the method, different patterns/characters of the same seal are output, and ink discharged from the micro-tubes is generally in a circular shape on paper, so that the flow direction of the ink on the paper is further accurately controlled, and further the accurate control is further realized through the guide sheets among the micro-tubes. Through the direction cooperation of the microtubule gap guide sheet, the direction and the shape of the microtubule ink outlet are further finely controlled, smoother and finer characters and images can be formed, and the effect of oil printing and moistening on paper is improved.

Because the fineness of the patterns or characters of the stamp is influenced by the density of the capillary micro-tubes, for further accurate control, the on-off quantity of part of the capillary micro-tubes is opened and closed at a specific frequency when the stamp performs negative pressure ink absorption, so as to control the ink inlet quantity. Furthermore, when the stamp performs stamping action, the MCU/CPU on the stamp also controls the frequency of the switching value of the specified capillary micro-tube and controls the ink output quantity of the specified shape, so as to further improve the effect of characters or patterns of the stamp.

As shown in fig. 6, the switching control of 2 micro-pipes is taken as an example. The on/off periods of the micro-tube A and the micro-tube B are set as T (A) and T (B), respectively. When forming pattern 1, the duty ratio of opening micropipe a is configured as d (a) ═ th (a)/t (a). Microtube B opening duty cycle is configured as d (B) ═ th (B)/t (B). Similarly, other micro-tubes cooperate to form the pattern/character 1 according to a specific duty ratio or switching state. And triggering control pattern or character conversion according to a pressure sensor or cloud command, and changing the combination of the switching duty ratios of the micro-tubes according to the configuration to form a pattern/character 2.

According to the intelligent seal, due to the design that the array type seal capillary microtubes are separated from the printing ink, the seal content can be programmed, and meanwhile, the risk that the seal content is cracked by analyzing the array type seal according to the using amount of the printing ink is avoided. Meanwhile, due to the matching of the duty ratio of the switch and the guide sheet when the capillary micro-tube is in positive and negative pressure, the ink outlet effect is better and controllable. One seal can print various patterns, and the capability of outputting various patterns and characters of one seal is realized. And the digital management of the seal is realized by matching with local authentication, cloud authorization and data interaction, one seal can be used by multiple people, different seal contents are output according to different authorities respectively, and the unified cluster management of the seal is realized.
