[0047] The control module includes a detection unit and a control unit. The detection unit is used to detect the position of each printing block 4. The input and output ends of the control unit are electrically connected to the output end of the detection unit and the input end of the coil layer respectively, so as to adjust the position of each printing block 4.

[0048] In a specific embodiment, the cover plate 2 is an iron arc-shaped structure.

[0049] In one embodiment, a shell is provided on the cover plate 2, and a display screen 6 and a control key 7 are provided on the shell. The input end of the display screen 6 and the output end of the control key 7 are both electrically connected to the control unit.

[0050] In a specific embodiment, the cross-section of the housing is rectangular.

[0051] In a specific embodiment, the housing includes an upper cover 8 and a shell 9 , and the display screen 6 and the control keys 7 are both arranged on the upper cover 8 .

[0052] Of course, it should be appreciated that the cross-sections of the above structures may also be other shapes, and the present invention is not limited thereto. Any shape that can achieve the same technical effect as the present invention is within the protection scope of the present invention.

[0053] In a specific embodiment, the control unit is a PCB control circuit board 10 , and the PCB control circuit board 10 is arranged at the upper end inside the upper cover 8 .

[0054] In one embodiment, a central shaft 11 and a bearing 12 are provided in the cover plate 2. The central shaft 11 is passed through the rotor 3 through the bearing 12, and its two ends are fixed to the housing. Specifically, the central shaft is used to limit the rotor of the rotating module, and the bearing is used to ensure the smoothness of the rotor rotation.

[0055] In a specific embodiment, six rotating modules are provided in the cover plate 2, and each printing block 4 on each of the six rotating modules has a different digital shape. When the control unit controls the rotation of each printing block on each rotating module, the printing date can be quickly changed.

[0056] In one embodiment, the coil layer includes a plurality of coil poles 13 , and the plurality of coil poles 13 are evenly distributed on the inner wall of the cover plate 2 along the circumference of the cover plate 2 .

[0057] In a specific embodiment, the detection unit is a Hall sensor 14 , and the Hall sensor 14 is disposed on the inner wall of the cover plate 2 close to the bottom plate 1 .

[0058] Specifically, the coil columns are electrically connected to the PCB control circuit board. The PCB control circuit board generates a magnetic field rotating around the center of the rotor by changing the alternating frequency and waveform of the current wave input to the coil columns. The magnetic poles of two adjacent magnets on the rotor are opposite, so that the magnetic field can drive the magnets to rotate, thereby driving the rotor to rotate. The main function of the Hall sensor is to identify the position information of each printing block on the rotor, and convert the position information into an electrical signal, and then transmit the electrical signal to the input end of the PCB control circuit board, so that the PCB control circuit board can determine whether to power the coil columns according to the electrical signal, thereby realizing the control of the position of each printing block.

[0059] In one embodiment, the control module further includes a communication unit, the input end of the communication unit is used to communicate with an external electronic device, and the output end thereof is electrically connected to the input end of the control unit.

[0061] When the smart seal of the present invention is in use, the user can choose to issue instructions to the control unit through control keys or external electronic devices. The control unit supplies power to a plurality of coil columns so that the rotor drives each printing block to rotate. At the same time, the Hall sensor detects the position of each printing block and transmits the detection result to the control unit for display on the display screen. When a certain printing block in each printing block rotates to a specified position, the user can operate again to make the control unit cut off the power to the plurality of coil columns and stop the rotor from rotating. Then, the user can pick up the smart seal and print the pattern of a certain printing block on the substrate. During use, the position of each printing block can be adjusted through the above operation until printing is completed.

[0062] The smart seal proposed by the present invention has a coil layer for generating a magnetic field after power is applied in the cover plate, so that the rotor with a magnet inside can have a tendency of relative movement under the action of the magnetic field, thereby driving the rotor to rotate, and driving a number of printing blocks evenly distributed on it along its circumference to rotate, so that each of the printing blocks can be exposed to the outside of the bottom plate through the through slot, so as to realize printing on the substrate. Then, through the setting of the detection unit and the control unit, the detection unit can detect the position of each printing block, and the control unit can be used to adjust the position of each printing block.

[0063] Furthermore, by setting up a communication unit, the input end of the communication unit is used to communicate with an external electronic device, and its output end is electrically connected to the input end of the control unit, so that the smart seal can also be controlled by the external electronic device, which is conducive to the use of the smart seal.

[0064] Compared with the existing dial wheel seal, the smart seal of the present invention realizes precise control of each printing block through the control unit and the detection unit, and realizes the rotation of the rotor and the rapid movement of each printing block through the magnet and the magnetic field, abandoning the inefficient driving method of manual dial wheel, making it more convenient to use the seal and realizing efficient printing of the seal.
