DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0030] A seal device with an anti-counterfeiting function comprises an outer shell 1, an inner shell 2 slidably connected to the inside of the outer shell 1, a seal assembly 5 and an automatic anti-counterfeiting seal device 9 arranged inside the inner shell 2, wherein the top of the inner shell 2 and the inside of the outer shell 1 are connected by an elastic spring 3, the elastic force of the spring 3 can support the weight inside and outside the outer shell 1 and generate a continuous upward movement trend, and slide rails 21 are provided on both sides of the inner shell 2. It should be noted that sliding holes 11 larger than the maximum width of the left and right slide rails 21 are provided on both sides of the outer shell 1, and the position of the sliding hole 11 also needs to be set at the end of the top of the slide rail 21. The movement trajectory of the slide rail 21 needs to be S-shaped, and the slide rail 21 and the sliding hole 11 are connected by a guide rod 4. This setting is to avoid the guide rod 4 from interfering with the sliding hole 11 when moving along the slide rail 21, wherein the width of the guide rod 4 is less than the minimum width of the slide rail 21, and the seal assembly 5 is fixedly connected to the guide rod 4. 2 An Indonesian plate 6 for replenishing the ink of the seal assembly 5 is provided on the side deviating from the slide rail 21. When the outer shell 1 is subjected to downward pressure, the sliding hole 11 will also generate downward pressure to make the guide rod 4 move downward along the slide rail 21. Since the slide rail 21 is not a straight track, the elastic force generated by the spring 3 gradually increases when it moves to the curved area, and the inner shell 2 is pressed relative to the printing surface. This seal assembly 5 can rotate in the direction of the track of the slide rail 21. When it is released, the rotation principle is the same as here and will not be repeated here. When the outer shell 1 is not subjected to pressure, it is necessary to note that the setting of the slide rail 21 must meet the requirements of the seal assembly 5 aligning with the Indonesian plate 6. The bottom of the inner shell 2 is provided with an inner shell baffle 911, and the surface of the inner shell baffle 911 is provided with a through hole for matching the seal assembly 5 and the automatic anti-counterfeiting seal device 9. The inner shell baffle 911 and the inner shell 2 need to be fixed and installed by anti-dismantling screws. This setting is to increase the difficulty of disassembly of this embodiment for counterfeiters.

[0031] The seal assembly 5 includes a seal and a seal boss. The seal boss is provided with a through hole that matches the guide rod 4. A threaded column is provided on one side of the seal boss. The seal is provided with a threaded hole that matches the threaded column. The design of the seal and the seal boss shell being removable enables this embodiment to provide customers with seals with different contents before production.

[0032] An image acquisition device 7 and a QR code generating device 8 are also provided on one side of the outer shell 1, wherein a boss for storing the QR code generating device 8 is provided on the outer side of the outer shell 1, and a fingerprint recognition module 12, a display screen 13 and a button module 14 are provided on the top of the outer shell 1. The fingerprint recognition module 12 is used to control the extension and retraction of the automatic anti-counterfeiting seal device 9 and unlock the display screen 13. The display screen 13 communicates with the image acquisition device 7 and displays its picture. The button module 14 is used to control the display screen 13 to query the collected image records. The QR code generating device 8 can print different QR code patterns on paper.

[0033] The automatic anti-counterfeiting seal device 9 includes an anti-counterfeiting shell 91, a motor 92, a drive shaft 93, a driven wheel 94, a rack 95, an anti-counterfeiting mark 96 and an anti-counterfeiting cover 97. The motor 92 is fixedly installed inside the anti-counterfeiting shell 91, and the end of the motor 92 is fixedly connected to the drive shaft 93. The surface of the drive shaft 93 is provided with a thread groove 931. The surface of the driven wheel 94 is provided with a groove 941 that is rotatably connected to the thread groove 931. The thread groove 931 is vertically arranged relative to the groove 941. The bottom of the driven wheel 94 is provided with a driven gear 942. One side of the rack 95 is provided with a plurality of tooth grooves 951 that match the driven gear 942. The rack 95 is slidably connected to the inside of the anti-counterfeiting shell 91. The thread groove 931 is vertically arranged relative to the groove 1, which can rotate the motor 92 left and right. It becomes the forward and backward linear motion of the driven wheel 94, thereby realizing the forward and backward telescopic motion of the anti-counterfeiting mark 96. In this embodiment, the front end and the rear end of the sliding rack 95 also need corresponding limit blocks to limit it. One end of the rack 95 is fixedly connected to the anti-counterfeiting mark 96. The interior of the anti-counterfeiting mark 96 is hollow and stores ultraviolet fluorescent ink. The ultraviolet fluorescent ink is invisible or colorless under normal circumstances. However, it presents a clear and bright fluorescent pattern under ultraviolet light, so that the signatory can promptly identify the authenticity of the seal. Since the automatic anti-counterfeiting seal device 9 cannot be replenished with dyes through Indonesia, the seal surface of the anti-counterfeiting mark 96 is embedded in the open-pore sponge rubber until it contacts the internal ultraviolet fluorescent ink. The bubbles of the open-pore sponge rubber are interconnected or completely connected, and gas or liquid can pass through to achieve the anti-counterfeiting seal effect after ink absorption.

[0034] A partition is provided inside the outer shell 1, and the partition is provided with a through hole corresponding to the power supply position of the motor 92 and is fixedly connected to a spring 3 at the bottom. The upper part of the partition is fixedly connected to the main control board 15, the battery pack 16, the GPS positioning device 17, the wireless communication module 18 and the hand-cranked generator 19. A charging interface is provided on one side of the outer shell 1 for charging the battery pack 16. The main control board 15 is used to monitor the battery voltage and charge and discharge current of the battery pack 16 and to control the mutual communication of various components. The GPS positioning device 17 is used to locate the position information of the device and transmit the information to the main control board 15 for processing. The wireless communication module 18 is used to communicate with cloud data. The battery pack 16 is used to provide power to the device. The hand-cranked generator 19 is used to charge the battery pack 16. In this embodiment, the communication between the various modules or components is common knowledge for people in this field and will not be repeated here.

[0035] The hand-cranked generator 19 includes a rocker 191, a fixed block 192, a gear 193, and a DC generator 194. A gear 2 195 is provided on one side of the DC generator 194. The fixed block 192 is internally rotatably connected to the gear 193, and the top of the gear 193 is rotatably connected to the gear 2 195. The rocker 191 passes through the fixed block 192 and is fixedly connected to the gear 193. When power generation is required, the rocker 191 rotates the gear 193 to drive the gear 2 195. At this time, the coil cuts the magnetic lines of force in the magnetic field under the drive of the external force to generate an induced electromotive force. The internal coil forms a closed loop with the main control board 15 circuit through the brush, which can enable the DC generator 194 to generate current and charge the battery pack 16. This arrangement is to avoid the situation in which the device in this embodiment is forgotten to be charged when it is out for work.

[0036] The image acquisition device 7 is a camera, which includes a front cover 71, a rear cover 72, a lens 73 installed inside the rear cover 72, a battery pack 2 74, a digital substrate 75, a lighting unit 76, the lighting unit 76 and a USB interface. The lens 73 uses a photographic element composed of a CMOS sensor. The scene light enters the camera through the lens, and then passes through the infrared filter IRFilter to filter out the infrared light in the light entering the lens, and then reaches the sensor. The sensor converts the optical signal into an electrical signal, and then passes through the internal digital substrate 75 with a conversion circuit that can convert the image signal into a digital signal and an analog signal. After processing, it is converted into RGB, YUV and other formats for output. The lighting unit 76 uses a flash with TTL mode. This setting is used to obtain a correct exposure value. The USB interface is used to communicate with the main control board 15. Since cameras are commonly used components in this field, they will not be described in detail here.

[0037] The two-dimensional code generating device 8 includes a coding upper cover 81, a coding shell 82, and an ink cartridge 83, a first clamping plate 84, a second clamping plate 85 and a PCB board 86 installed inside the shell. The top of the coding shell 82 is provided with a notch. The top of the coding shell 82 is rotatably connected to a rotating cover 87 and can cover the notch when closed. The ink cartridge is an ink cartridge used in a handheld inkjet printer in the prior art. A nozzle is provided on one side of the ink cartridge 83. The nozzle is a thermal bubble inkjet technology, and the nozzle has multiple nozzle holes with a diameter of about 50 microns. These nozzles are arranged in a high density. After receiving the print signal, they use electric current to heat the ink to about 260 degrees in a very short moment. The local ink is heated to form bubbles, which expand and spray the ink to form various QR code patterns. There is a sealing door in front of the ink cartridge, and a soft silicone strip is provided on the sealing door to block the nozzle. When not in use, the door can be closed. The first clamping plate 84 and the second clamping plate 85 are fixed to each other to form a cavity. The PCB board 86 and the ink cartridge 83 are installed inside the cavity. It should be noted that the ink cartridge 83 is detachably installed inside the cavity. The top of the ink cartridge 83 has a PCB thin plate that communicates with the PCB board 86 after installation. An elastic member is provided inside the cavity to hold the main ink cartridge 83. The PC The B board 86 includes a control module, a storage module, a power module and a communication module. The storage module is used to store printing information. The control module is electrically connected to the storage module and the nozzle. The communication module communicates and edits with the computer through a data cable. The power module is connected to the main control board 15 through a USB interface. The side of the coding housing 82 close to the nozzle is provided with a main roller 88, a secondary roller 89, and a laser displacement sensor 80. When the laser displacement sensor 80 and the main roller 88 monitor the displacement of the nozzle, it will be converted into an electrical signal through the encoder. After determining the position, the signal will be fed back to the control module and the printing will be delayed. During the printing process, the secondary roller 89 can slide to provide sliding support during coding.

[0038] Directions:

[0039] Before use, first make sure that the device is powered on and that the anti-counterfeiting mark 96 inside the automatic anti-counterfeiting seal device 9 is parallel to the paper surface and can be printed. Then, the fingerprint recognition module 12 verifies the user's information.

[0040] After the fingerprint verification is successful, the automatic anti-counterfeiting seal device 9 retracts the anti-counterfeiting mark 96 inward under the rotation of the motor 92. When the user presses the outer shell 1 to generate downward pressure, the sliding hole 11 also generates downward pressure to make the guide rod 4 move downward along the slide rail 21. Since the slide rail 21 is not a straight track, the elastic force generated by the spring 3 gradually increases when it moves to the curved area. The inner shell 2 is pressed relative to the printing surface. Therefore, the seal assembly 5 can be rotated in the direction of the track of the slide rail 21 until the printing surface is parallel to the paper surface. Then, the image acquisition device 7 provided on one side of the outer shell is used to use the lens 73 to collect the collected seal information, imprint information, and various public The company information and signature information are uploaded to the cloud to form blockchain data to prevent tampering by others. Finally, the QR code generating device 8 is used to slide on the paper surface. At this time, the laser displacement sensor 80 and the main roller 88 monitor the displacement of the nozzle and convert it into an electrical signal through the encoder. After determining the position, the signal will be fed back to the control module and delayed to start printing. After receiving the printing signal, the ink will be heated in a very short time to form bubbles, which will expand and spray the ink to form a QR code. After scanning the QR code, the user needs to fill in the relevant information. After successful filling, the signatory can promptly identify the authenticity of the seal. If the filling fails, the other party's location information will also be obtained, so as to achieve the purpose of tracing the counterfeiter.

[0041] If the fingerprint verification fails or the fingerprint is not verified within one minute, the stamping operation and the QR code generating device 8 can still be used normally. The difference from the successful verification mentioned above is that the seal information collected by the image acquisition device 7 cannot be obtained, and when stamping, the motor 92 in the automatic anti-counterfeiting stamp device 9 will not rotate to retract the anti-counterfeiting mark 96 inward, so the anti-counterfeiting mark 96 will be left on the paper surface. Since the pattern printed by the anti-counterfeiting mark 96 is an invisible font that is only displayed under ultraviolet light, it can effectively confuse the imposter, and the signatory personnel can identify the authenticity of the seal.

[0042] When charging is needed, the hand-cranked generator 19 provided inside the outer shell 1 can be used to rotate gear 1 193 through the rocker 191 to drive gear 2 195. At this time, an induced electromotive force is generated by the external force, and the internal coil forms a closed loop with the main control board 15 circuit through the brush, which can enable the DC generator 194 to generate current and charge the battery pack 16.

[0043] After use, there is a sealing door in front of the ink cartridge, which can be closed when not in use.

[0044] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
