Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, 2 and 3, the anti-pilferage stamp with automatic ink application of the present embodiment mainly includes a base 1, a housing 2, a stamp plate 3, an inking plate 4, two coreless motors 5, a probe 6, four limit lugs 7, a lead screw nut assembly 8, four straight rods 9, a proximity sensor 10, a motor 11, a point contact 12, four connecting rods 13, a circuit board 14, a battery 15, four springs 16, four spring bottom holders 17, an inking plate connecting rod 18 and an ink adding hole 19. The main structure of the stamp is a stamp base 1 and a housing 2. Four straight rods 9 are fixedly connected on the shell 2, the straight rods 9 are sleeved with springs 16 and then are enabled to penetrate through four limiting lugs 7 of the stamp base 1 to be locked, one ends of the springs 16 are pressed on the spring bottom fixing devices 17, and the other ends of the springs are pressed on one sides of the limiting lugs 7. The stamp base 1 and the housing 2 are thus combined, and when the housing 2 is pressed downward, the spring 16 is compressed, and when the applied force is removed, the housing 2 will spring up and return to its original shape by the force of the compression of the spring 16. The shell 2 fixes the motor 11 through four connecting rods 13, one end of the screw-nut component 8 is connected with the motor 11, the other end of the screw-nut component 8 is connected with the seal plate 3, and the motor 11 controls the extension of the seal plate 3 by controlling the extension of the screw-nut component 8. Two coreless motors 5 are mounted on the stamp base 1, output shafts of the two coreless motors are connected with the printing pad 4 through a printing pad connecting rod 18, and the function of controlling the movement of the printing pad 4 by the coreless motors 5 can be realized through the connecting mode. A proximity sensor 10 is provided under the stamp base 1, by which it is determined whether the pad 4 is lowered, to determine the next operation of the stamp. In this state, a gap of 5mm exists between the stamp plate 3 and the pad 4. An STM32 controller, a wireless transmission module and an acceleration sensor are mounted on the circuit board 14. The circuit board 14 is powered by the battery 15, can control the rotation of the motor 11 and the hollow cup motor 5, can collect the data of the acceleration sensor and the proximity sensor 10, and can end commands, send data and alarm through the wireless transmission module.

As shown in fig. 8, which is a reference drawing of axis X, Y, this embodiment provides that the center of the stamp is directed toward the operator, toward the proximity sensor on the stamp base, and toward the ground.

As shown in fig. 2, the process of inking the stamp each time is as follows: motor 11 drive screw-nut subassembly 8 in the seal and then drive seal board 3 and stretch 5mm and just contact printing pad 4 to the purpose of being stained with china ink has been realized.

Referring to FIG. 3, when the user authorizes the seal to be inked or the number of imprintable times, the seal is unlocked. During unlocking, the seal firstly executes the process of ink dipping of the seal, namely, a motor 11 in the seal drives the lead screw nut component 8 to further drive the seal plate 3 to extend out for 5mm and just contact the printing plate 4. Once the ink is stained, the hollow cup motor 5 immediately drives the Indonesia plate 4 to rotate, and when the Indonesia plate rotates 90 degrees, namely the Indonesia plate is close to the proximity sensor 10, the seal unlocking is finished. After the unlocking is finished, the Indonesia plate 4 is close to the proximity sensor 10 and is also vertical to the seal plate 3, at the moment, the ink adding hole of the Indonesia plate is exposed to a user, and the user can conveniently add the ink.

Referring to fig. 4, after the stamp is unlocked, the user can use the stamp for the authorized number of times. Four straight rods 9 of the stamp are fixedly connected on the shell 2, the straight rods 9 are sleeved with springs 16 and then are enabled to penetrate through four limiting lugs 7 of the stamp base 1 to be locked, one ends of the springs 16 are pressed on the spring bottom fixing devices 17, and the other ends of the springs are pressed on one sides of the limiting lugs 7. Spring 16 compresses when the user presses housing 2 downward when the user fully presses housing 2, seal plate 4 just beyond seal base 1, a position that allows the user to stamp without damaging the stamp face.

Referring to fig. 5, when the number of stamping authorized for the stamp is zero, the controller in the circuit board 14 controls the motor 11 to rotate the stamp plate 3 to retract by 5mm by rotating the lead screw nut assembly 8, and controls the coreless motor 5 to rotate the Indonesia plate 4 by 90 degrees to a position parallel to the stamp plate 3. Therefore, when the seal is illegally stamped, the seal plate 3 at the moment is retracted by nearly 5mm from the bottom of the seal base 1, and the seal cannot be stamped even if the seal is forcibly pressed. Meanwhile, when the acceleration sensor detects that downward acceleration still exists in the locking process, namely the seal is stolen and covered by multiple covers, the controller sends an alarm signal to a user through the wireless module.

As shown in fig. 9, the present embodiment introduces a counting judgment algorithm corresponding to the acceleration sensor to improve the counting accuracy, and the mechanical counting of the present invention uses the counting number of the mechanical counting only when the acceleration sensor counts and determines that the counting is illegal (i.e. the algorithm misjudges), and the mechanical counting counts again. In the embodiment, ax, ay and az are respectively defined as acceleration values in each axial direction, and the unit is mm; lx, ly and lz are respectively defined as displacement values of each axial direction, and the unit is mm; tx, ty are respectively defined as the duration of acceleration greater than 2mm and less than 5 mm; the pressing stroke of the stamp is defined to be 100 mm. The judgment algorithm for reasonably stamping the judgment seal of the acceleration sensor is as follows:

(1) the accelerations ax, ay, and az are read X, Y, Z from the axial direction of the shaft, respectively, after acceleration and initialization.

(2) If the absolute value | ax | of the read X-axis acceleration value is smaller than 2mm/s and the absolute value | ay | of the read Y-axis acceleration value is also smaller than 2mm/s, the read Z-axis acceleration value ax is always larger than 2mm/s and the displacement lz is larger than 100mm, and the absolute values | lx |, | ly |, of the displacements of the X axis and the Y axis are both smaller than 50mm in the process, the accelerometer count is increased by 1;

(3) if the absolute value | ax | of the read X-axis acceleration value is less than 2mm/s, the absolute value | ay | of the read Y-axis acceleration value is also less than 2mm/s, and the read Z-axis acceleration value ax is less than or equal to 2mm/s, determining that the time is illegal;

(4) if the absolute values | ax | and | ay | of the acceleration values of one or both of the read X or Y axes are greater than or equal to 2mm/s but less than 5mm/s and the time of each occurrence is less than 2s, the accelerometer count is increased by 1 when the read Z-axis acceleration value ax is always greater than 2mm/s and the displacement lz is greater than 100mm and the absolute values | lx |, | ly | of the displacements of the X and Y axes are less than 50mm in the process;

(5) if the absolute values | ax | and | ay | of the acceleration values of one or both of the read X-axis and Y-axis are greater than or equal to 2mm/s but less than 5mm/s and the time of each existence is less than 2s, but the read acceleration value ax of the Z-axis is less than or equal to 2mm/s, the judgment is illegal at this time;

(6) if the absolute values | ax | and | ay | of the acceleration values of one or both of the read X-axis and Y-axis are more than or equal to 2mm/s and less than 5mm/s, but the time when one or two axes appear at the same time is more than or equal to 2s, determining that the time is illegal;

(7) in the single counting process, once the displacement | lx |, | ly | of one of the X or Y axes or the displacement | lx | and | ly | of the two axes simultaneously appear, the illegal time is judged when the displacement | lx | and | ly | are more than or equal to 50 mm.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
