Description

Technical Field

[0001] The present invention relates to the field of seal technology, and in particular to an intelligent verification device for an open seal machine. Background Art

[0002] Traditional stamp affixing machines typically have a closed structure, which significantly limits the size and shape of objects that can be stamped. Furthermore, they are inconvenient for maintenance and stamp replacement, requiring complex disassembly procedures. Furthermore, for specialized applications, such as stamping large documents or irregularly shaped items, traditional stamp affixing machines often fall short. Therefore, a stamp affixing machine with an open structure, flexible operation, and easy maintenance is needed.

[0003] Chinese patent publication number: CN117252532A, discloses a physical seal management and control system for the power industry and its seal-using device, including: using an information system to upload seal materials and submit seal applications, which can distinguish whether the seal is used for routine matters, thereby determining different approval processes; using a seal control program to manage company seals to change the traditional seal-using mode, and using the seal control program for fully automatic printing and stamping, supporting batch automatic printing and stamping, interline stamping, and keyword stamping; using a seal control program to manage company seals; calling the seal control program to automatically print and stamp after the seal approval is passed; an application process needs to be initiated when replacing and retrieving seals; the company seal machine replaces the seal through the seal-using device; It can be seen that the above technical solution has the following problems: it does not take into account the adoption of an open structure, and cannot stamp objects of various sizes and irregular shapes, which affects the stamping efficiency. Summary of the Invention

[0004] To this end, the present invention provides an intelligent verification device for an open-type stamping machine, so as to overcome the problem in the prior art that articles of various sizes and irregular shapes cannot be stamped, thereby affecting the stamping efficiency.

[0005] To achieve the above-mentioned object, the present invention provides an intelligent verification device for an open printer, comprising:

[0006] control Panel;

[0007] The housing includes a guide rail fixedly disposed inside the housing and a rack fixed inside the top end thereof;

[0008] Use stamp box;

[0009] A moving unit, which is used to control the movement of the ink box along the guide rail, includes a plurality of moving sleeves respectively mounted on the corresponding guide rails, a connecting bracket fixedly mounted on the inner side wall of the ink box and fixedly connected to each moving sleeve, a moving motor fixed to one side of the connecting bracket for driving the ink box, and a driving gear provided at the output end of the moving motor for cooperating with the rack to control the movement of the ink box;

[0010] A stamp storage unit for storing stamps includes a rotating base fixedly mounted on the inner side wall of the stamp box for loading other components, a rotating motor fixedly mounted above the rotating base with its output shaft extending through the rotating base, a stamp storage bracket connected to the output end of the rotating motor for loading stamps, and a rotating drum fixedly mounted above the stamp storage bracket and surrounding the output end to rotate when the rotating motor is running.

[0011] The printing unit is used to control the longitudinal movement of the corresponding seal, and includes a printing base fixedly connected to one side of the connecting bracket, a driving column located below the printing base and above the corresponding seal to provide downward pressure to the seal, and a printing motor located above the printing base to control the operation of the driving column.

[0012] Furthermore, the chapter storage unit further includes:

[0013] a plurality of positioning holes, each of which is respectively provided on the side wall of the rotating drum;

[0014] A first positioning sensor is fixedly arranged on the lower surface of the rotating base and is used to detect the position of the seal by identifying the positioning hole;

[0015] A plurality of seal tubes are provided, each of which is fixed relative to the seal storage bracket, and each of which can be used to fix and carry a single seal.

[0016] Furthermore, the badge holder includes:

[0017] A plurality of reset guide rails, which pass through the chapter tube and are used to limit the displacement direction of the chapter tube;

[0018] A plurality of reset springs are each sleeved on the reset guide rail and the sleeve location is located below the chapter tube for controlling the chapter tube to reset.

[0019] Furthermore, the printing unit further includes:

[0020] A plurality of buffer columns, each of which is fixed above the printing base to limit the moving path of the printing motor;

[0021] A plurality of buffer springs are each sleeved on the buffer column to limit the maximum moving path of the printing motor.

[0022] Furthermore, the printing unit further includes:

[0023] The buffer platform is mounted on each buffer column and is located below each buffer spring. It is fixed below the printing motor to fix the printing motor and the printing base relative to each other.

[0024] Furthermore, the housing also includes an ink pad located below the ink box.

[0025] Furthermore, the printing unit further includes:

[0026] A printing touch sheet is provided on one side of the buffer table;

[0027] A stamp sensor is provided on the stamp base and is used to determine the running time of the driving column by cooperating with the stamp contact piece;

[0028] A buffer contact piece, which is arranged on one side of the buffer platform;

[0029] A buffer sensor is provided on the printing base and is used for detecting whether the buffer base is displaced by cooperating with the buffer contact piece.

[0030] Furthermore, the driving gear is meshed with the rack.

[0031] Furthermore, the housing further comprises a stamping plate extending outwards to provide a stamping platform;

[0032] The printing plate is provided with a plurality of fixing clips for fixing the documents to be stamped.

[0033] Furthermore, the output shaft of the seal motor is connected to the driving column to drive the seal located above the ink pad to move longitudinally.

[0034] Compared with the prior art, the beneficial effect of the present invention lies in that, by setting a mobile unit, the movement of the seal box is controlled so that the seal device can be applied to documents of multiple sizes. By setting a seal storage unit, the storage of multiple seals can be realized, and the use of seals is more convenient. The seals within the authority within the seal storage unit can be selected for use through the control panel according to the preset authority restrictions, thereby improving the security of seal use. The seal unit realizes the dipping of ink and the stamping action, thereby improving the efficiency of seal use.

[0035] Furthermore, by setting up a seal storage unit and using a seal device, the use needs of various seals can be met. The various components in the seal storage unit work together to accurately select the corresponding seal. The seals are stored through the seal storage bracket, which can effectively save the floor space and retrieval efficiency of each seal. The positioning hole and the first positioning sensor work together to effectively improve the accuracy of seal retrieval. By setting a reset spring, the seal can be reset in time, effectively controlling the dipping time of the ink pad, and ensuring the uniformity of the ink pad dipping. By setting a seal tube, the stability of the seal is improved, ensuring the clarity of the seal when used, and further improving the efficiency of seal use.

[0036] Specifically, the buffer platform, buffer column, and buffer spring work in concert to effectively prevent damage to the seal barrel and seal motor due to excessive pressure exerted on the seal barrel by the drive column due to excessive operating time, thereby increasing the service life of the seal mechanism. The seal motor drives the drive column to move, applying downward pressure to the seal barrel, causing it to move downward, thereby quickly completing the action of dipping the seal in ink or stamping. By providing a buffer contact and buffer sensor to precisely monitor the operation of the seal motor, the control accuracy of the seal barrel is further improved, enhancing the accuracy of stamping and dipping the seal in ink. By providing a seal sensor and seal contact, abnormal seal conditions are monitored, the buffering status of the seal motor's upward movement is promptly determined, and the internal operating conditions of the seal box are accurately captured. By providing each positioning column to effectively limit the operating trajectory of the drive column, while ensuring that the drive column accurately applies pressure to the corresponding seal barrel, further improving seal efficiency.

[0037] Furthermore, the open structure provides users with a larger operating space, making it more convenient to place stamped objects without having to worry about placement difficulties caused by the closed structure of the device, thereby improving the convenience and efficiency of operation.

[0038] Furthermore, when maintaining or replacing stamps, there is no need for complex disassembly procedures; the stamps in the stamp barrel can be directly replaced or other components can be maintained. This reduces the risk of equipment damage caused by complex maintenance processes and extends the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0052] See also Figure 1, which is a front view of an intelligent verification device for an open-type stamping machine according to an embodiment of the present invention. The intelligent verification device for an open-type stamping machine according to the present invention comprises a control panel 1, a housing 2, a stamp plate 23, a stamp box 3, and a plurality of fixing clips 4. The control panel 1 is fixed to the surface of the housing 2 for user interaction. The housing 2 includes a stamp plate 23 for providing a platform for stamping. The stamp box 3 is located within the housing 2 for storing stamps.

[0053] It is possible to store several seals in the seal box 3, and determine the correspondence between the seal fixed position and the seal in advance through the control panel 1. When the user starts to use the seal, the seal to be used is determined through the control panel 1, and the document to be stamped is placed in the corresponding position of the stamping plate 23. The seal box 3 moves toward the stamping plate 23 to perform the stamping action.

[0054] The fixing clips 4 provided on the printing plate 23 can be used to fix the document to be stamped to ensure stable stamping; each fixing clip 4 can respectively clamp different parts of the document to be stamped to achieve the function of stamping the perforation.

[0055] See also Figure 2 and Figure 3 As shown, they are respectively an internal structure diagram and an internal side view of an intelligent verification device for an open-type printing machine according to an embodiment of the present invention. The intelligent verification device for an open-type printing machine according to the present invention comprises a moving unit (not shown in the figure), a stamp storage unit (not shown in the figure) and a stamp unit (not shown in the figure). The moving unit is used to control the stamp box 3 to move along the guide rail 22. The stamp storage unit is arranged in the stamp box 3 to store stamps and move the stamps to be used to the corresponding positions. The stamp unit is arranged in the stamp box 3 and above the stamp storage unit to control the stamp to be used to move longitudinally to achieve the action of stamping or dipping in ink.

[0056] When the user selects the seal to be used through the control panel 1, the seal storage unit rotates the seal to be used to the corresponding position, the printing unit controls the seal to be used to move longitudinally to dip in the ink, and releases the pressure on the seal storage unit after determining that the dipping of the ink is completed, and the seal is reset. The moving unit drives the seal box 3 to move to the corresponding position of the printing plate 23. The printing unit controls the seal to be used to move longitudinally to achieve the stamping action, and releases the pressure on the seal storage unit after the stamping is completed, and the seal is reset. The moving unit drives the seal box 3 to move back to the initial position.

[0057] See also Figure 4, which is a schematic diagram of the structure of the mobile unit according to an embodiment of the present invention; the housing 2 of the present invention includes a rack 21, a guide rail 22, and an ink pad 24. The rack 21 is fixed to the top interior of the housing 2 and controls the movement of the ink box 3. The guide rail 22 is fixedly mounted within the housing 2 to limit the movement direction of the ink box 3. The ink pad 24 is disposed within the housing 2 and below the ink box 3 to provide ink.

[0058] When the ink is started, the ink box 3 takes the ink pad from the ink pad table 24 and moves along the guide rail 22 via the rack 21 .

[0059] Specifically, the mobile unit of the present invention includes a connecting bracket 311, several fixed plates (not shown), a mobile motor 314, several movable sleeves 221, and a drive gear 313. Each movable sleeve 221 is respectively sleeved on the guide rail 22 and movably connected to the guide rail 22. The connecting bracket 311 is fixedly mounted on the inner wall of the ink box 3 and is fixedly connected to each movable sleeve 221 via each fixed plate, thereby fixing the ink box 3 relative to each unit. The mobile motor 314 is fixed to one side of the connecting bracket 311 to drive the ink box 3. The drive gear 313 is located at the output end of the mobile motor 314 to cooperate with the rack 21 to complete the movement of the ink box 3.

[0060] When the printing unit completes the dipping of ink or the stamping action, the moving motor 314 fixed on the connecting bracket 311 drives the driving gear 313 to rotate, and the driving gear 313 rotates along the rack 21, thereby driving the connecting bracket 311 to move along the guide rail 22, thereby driving the printing box 3 to complete the moving action.

[0061] By setting up a moving unit, the movement of the seal box 3 is controlled so that the seal device can be applied to documents of multiple sizes. By setting up a seal storage unit, multiple seals can be stored, making the use of seals more convenient. The seals within the authority within the seal storage unit can be selected for use through the control panel 1 according to the preset authority restrictions, thereby improving the security of seal use. The seal unit realizes the dipping of ink and the stamping action, thereby improving the efficiency of seal use.

[0062] See also Figure 5, which is a schematic structural diagram of a stamp storage unit according to an embodiment of the present invention. The stamp storage unit comprises a rotating base 322, a rotating motor 323, a stamp storage holder 325, a rotating drum 324, and a plurality of stamp cylinders 326. The rotating base 322 is fixed within the stamp box 3. The rotating motor 323 is fixedly mounted above the rotating base 322, and its output shaft (not shown) passes through the rotating base 322. The stamp storage holder 325 is connected to the output end of the rotating motor 323 to rotate the stamps loaded therein when the rotating motor 323 is in operation. The rotating drum 324 is fixed above the stamp storage holder 325 and is provided with a plurality of positioning holes 3211. Each stamp cylinder 326 is fixed relative to the stamp storage holder 325 to secure the stamps.

[0063] The rotating base 322 is provided with a first positioning sensor 3221 for cooperating with the positioning holes 3211 provided on the rotating drum 324 to determine whether the chapter tube 326 has rotated to a corresponding position.

[0064] The chapter storage bracket 325 includes a plurality of reset rails 3251 , each of which is sleeved with a reset spring 3252 . Each chapter tube 326 is sleeved on a corresponding reset rail 3251 , and the sleeve portion is located above each reset spring 3252 .

[0065] Specifically, the user can install the seals in each seal tube 326 respectively, and the rotating base 322 is fixedly set in the seal box 3 to fix the various components of the seal storage unit in the seal box 3. When using the seal, the rotating motor 323 fixedly set above the rotating base 322 runs, driving the various seal tubes 326 loaded on the seal storage bracket 325 to rotate, so that the corresponding seal tube 326 that needs to be stamped is located directly above the ink pad. At the same time, when the seal storage bracket 325 rotates, it drives the rotating drum 324 fixedly connected to it to rotate, and the first positioning sensor 3221 set on the rotating base 322 detects the various positioning holes 3211 opened on the rotating drum 324 to determine whether the seal tube 326 is rotated to the corresponding position according to the number of detected positioning holes 3211. The stamping unit applies downward pressure to the corresponding seal tube 326, and the seal tube 326 is restricted by the reset guide rail 3251 to move vertically downward to complete the action of stamping or dipping the ink. After the stamping unit is completed, the downward pressure is released. At this time, the corresponding seal tube 326 is forced by the reset spring 3252 mounted on the reset guide rail 3251 to move upward to complete the reset.

[0066] By setting up a seal storage unit and using a seal device, the use requirements of various seals can be met. The various components in the seal storage unit work together to accurately select the corresponding seal. The seals are stored through the seal storage bracket 325, which can effectively save the floor space and retrieval efficiency of each seal. The positioning hole 3211 and the first positioning sensor 3221 work together to effectively improve the accuracy of seal retrieval. By setting up a reset spring 3252, the seal is reset in time, and the dipping time of the ink is effectively controlled, ensuring the uniformity of the ink dipping. By setting up a seal tube 326, the stability of the seal is improved, ensuring the clarity of the seal when used, and further improving the efficiency of seal use.

[0067] See also Figure 6 、 Figure 7 and Figure 8 As shown, they are respectively a schematic structural diagram of the printing unit according to an embodiment of the present invention, a partial enlarged view of the printing unit, and a partial enlarged view of the buffer contact piece 3323 and the printing contact piece 3321; the printing unit according to the present invention includes a printing base 331, a plurality of buffer columns (not shown in the figure), a plurality of buffer springs 3312, a buffer base 332, a printing motor 333, and a driving column 335. The printing base 331 is fixedly connected to one side of the connecting bracket 311 to fix the printing unit in the printing box 3. Each of the buffer columns is fixed above the printing base 331 to limit the moving path of the printing motor 333. Each of the buffer springs 3312 is sleeved on the buffer column to provide buffering protection for the printing motor 333. The buffer platform 332 is mounted on and movably connected to the ink base 331. It is mounted on each of the buffer columns below each of the buffer springs 3312 to secure the stamp motor 333 relative to the ink base 331. The stamp motor 333 is fixed to the buffer platform 332. The drive column 335 is located below the ink base 331 and above the ink pad 24. It is controlled by the stamp motor 333 to move longitudinally, applying downward pressure to the seal on the ink pad 24.

[0068] A printing contact piece 3321 is provided on the side surface of the driving column 335 , and a printing sensor 3322 is provided on the side wall of the printing base 331 for determining the operating time of the driving column 335 by cooperating with the printing contact piece 3321 .

[0069] A buffer contact piece 3323 is provided on one side of the buffer platform 332 , and a buffer sensor 3324 is provided on the printing base 331 for detecting whether the buffer platform 332 is displaced by cooperating with the buffer contact piece 3323 .

[0070] The output shaft of the printing motor 333 is connected to the driving column 335 .

[0071] Specifically, when the seal storage unit determines that the corresponding seal tube 326 rotates to above the ink pad through the first positioning sensor 3221 and the positioning hole 3211, the seal motor 333 above the seal base 331 runs, and the output shaft rotates to drive the driving column 335 to move downward. The seal contact piece 3321 set on one side of the driving column 335 disengages from the seal sensor 3322 provided on the side wall of the seal base 331, and the seal sensor 3322 starts to record the running time of the driving column 335. The driving column 335 is controlled by the ink-applying motor 333 to apply downward pressure to the corresponding seal tube 326. After the ink is dipped, if the ink-applying motor 333 is still running, the buffer platform 332 drives the ink-applying motor 333 to move upward along the buffer column to reduce the damage caused by the ink-applying motor 333 to the ink pad 24 and the seal tube 326 when the pressure applied by the ink-applying motor 333 on the seal tube 326 is too large. At this time, the buffer platform 332 drives the buffer contact piece 3323 set on one side thereof to move, and the buffer sensor 3324 detects the buffering time of the upward buffering of the ink-applying motor 333 to determine the excessive operation of the ink-applying motor 333. The buffer spring 3312 provides buffering for the ink-applying motor 333.

[0072] Specifically, the buffer platform 332, buffer column, and buffer spring 3312 work together to effectively prevent damage to the seal barrel 326 and the seal motor 333 due to excessive pressure exerted on the seal barrel 326 by the drive column 335 due to excessive operation of the seal motor 333, thereby extending the service life of the seal device. The seal motor 333 drives the drive column 335 to move, exerting downward pressure on the seal barrel 326, causing it to move downward, thereby quickly completing the ink pad or stamping process. The provision of a buffer contact 3323 and a buffer sensor 3324 precisely monitors the operation of the seal motor 333, further improving the control accuracy of the seal barrel 326 and enhancing the precision of stamping and ink pad application. The provision of a seal sensor 3322 and a seal contact 3321 monitors abnormal seal application conditions, promptly determining the buffering status of the seal motor 333 during upward operation and accurately capturing the internal operating conditions of the seal box 3. By providing each positioning column 3313 , the running trajectory of the driving column 335 is effectively restricted, and while ensuring that the driving column 335 accurately applies pressure to the corresponding seal cylinder 326 , the efficiency of using seals is further improved.

[0073] Specifically, the intelligent verification device for an open printing machine also includes a central control unit (not shown in the figure), which is respectively connected to the control panel 1, the mobile unit and the printing unit, and is used to determine whether the printing is qualified based on the edge integrity, and when the printing is judged to be abnormal, it adjusts the operating parameters of each motor based on the detail completeness.

[0074] Specifically, the central control unit is used to determine whether the seal is qualified based on the edge integrity, including:

[0075] If the edge integrity is greater than the second preset edge integrity, the seal is determined to be qualified, and the seal unit is controlled to continue to operate using the current operating parameters;

[0076] If the edge integrity is less than or equal to the second preset edge integrity and greater than the first preset edge integrity, determining whether the seal is qualified based on the operating time of the driving column 335;

[0077] If the edge integrity is less than or equal to the first preset edge integrity, it is determined that the seal is abnormal, and the operating parameters of each motor are adjusted based on the detail integrity.

[0078] Specifically, the first preset edge integrity is selected within the interval [0.84, 0.86], and the second preset edge integrity is selected within the interval [0.92, 0.94].

[0079] Specifically, the housing 2 further includes a camera (not shown) disposed just above the stamping plate 23 for acquiring stamp image information of the document to be stamped on the stamping plate 23 .

[0080] Specifically, the seal contour information in the stamp image information is identified, and the ratio of the edge length of the seal contour information to a preset length is calculated to obtain the edge integrity.

[0081] Specifically, the preset length is the edge length of the actual seal pre-stored corresponding to the seal.

[0082] Specifically, the specific method for identifying seal contour information in the stamp image is not limited. The method can include reading the seal image, converting it to a grayscale image, and applying Gaussian blur to reduce noise. The Canny edge detection algorithm is used to find edges in the image. The findContours function is used to detect contours in the image. Seal contours are filtered out based on their area and perimeter. For the filtered seal contours, the arcLength function is used to calculate their edge lengths.

[0083] Specifically, the central control unit is used to determine whether the seal is qualified based on the running time of the driving column 335, including:

[0084] If the driving column 335 running time is less than or equal to the preset driving column 335 running time, it is determined that the stamp is abnormal, and the stamping time is adjusted to a corresponding value based on the thickness of the document to be stamped;

[0085] If the running time of the driving column 335 is greater than the preset running time of the driving column 335 , the second preset edge integrity is adjusted to a corresponding value based on the running time of the driving column 335 .

[0086] Specifically, the seal qualification is determined based on edge integrity. This edge integrity-based seal determination intuitively and quickly assesses the overall seal quality. When the edge integrity is less than or equal to a second preset edge integrity level and greater than a first preset edge integrity level, the influence of the operating time of the drive column 335 on the seal quality is considered, further refining the seal determination criteria. When the operating time of the drive column 335 is short, it is determined that the seal has not been able to stably cover the document to be stamped, resulting in an edge loss. In this case, the seal's dwell time on the paper is corrected based on the paper thickness, automatically adjusting the seal parameters based on the document to be stamped in the usage scenario. When the operating time of the drive column 335 is greater than the preset operating time, the slower descending speed of the drive column 335 enables the seal to more stably contact the paper. In this case, the seal in the stamped image may be partially blurred due to insufficient ink pad. In this case, adjusting the first preset edge integrity level lowers the qualification criteria, ensuring clear seals while reducing the frequency of ink pad replacement, further improving seal efficiency.

[0087] Specifically, the operating time of the driving column 335 is the time it takes for the seal contact piece 3321 to separate from the seal sensor 3322 as obtained by the seal sensor 3322. It can be understood that the stamping time can be adjusted by adjusting the operating parameters of the seal motor 333.

[0088] Specifically, the stamping time refers to the length of time the seal stays on the document to be stamped.

[0089] Specifically, the preset running time Q0 of the driving column 335 is selected within the interval [1.5s, 2s].

[0090] The central control unit is used to adjust the stamping time to a corresponding value based on the thickness of the document to be stamped, wherein the increase in the stamping time is proportional to the thickness of the document to be stamped.

[0091] In this embodiment, optionally,

[0092] comparing the thickness to a first predetermined thickness and a second predetermined thickness;

[0093] If the thickness is less than or equal to the first preset thickness, the stamping time is adjusted to 1.11 times the initial stamping time;

[0094] If the thickness is less than or equal to the second preset thickness and greater than the first preset thickness, the stamping time is adjusted to 1.15 times the initial stamping time;

[0095] If the thickness is greater than the second preset thickness, the stamping time is adjusted to 1.25 times the initial stamping time;

[0096] The first preset thickness is 0.1 mm, and the second preset thickness is 0.3 mm.

[0097] Specifically, the housing 2 further includes a distance measuring sensor (not shown) disposed just above the printing plate 23 for obtaining the thickness of the document to be stamped on the printing plate 23 .

[0098] Specifically, the central control unit is used to adjust the second preset edge integrity to a corresponding value based on the operating time of the driving column 335 , wherein the reduction range of the second preset edge integrity is proportional to the operating time of the driving column 335 .

[0099] In this embodiment, optionally,

[0100] Comparing the operating time of the driving column 335 with a first operating comparison threshold and a second operating comparison threshold;

[0101] If the operating time of the driving column 335 is less than or equal to the first operating comparison threshold, the second preset edge integrity is adjusted to 0.98 times the initial second preset edge integrity;

[0102] If the running time of the driving column 335 is less than or equal to the second running comparison threshold and greater than the first running comparison threshold, the second preset edge integrity is adjusted to 0.82 times the initial second preset edge integrity;

[0103] If the running time of the driving column 335 is greater than the second running comparison threshold, the second preset edge integrity is adjusted to 0.78 times the initial second preset edge integrity;

[0104] The first running comparison threshold is 1.6Q0, and the second running comparison threshold is 2Q0.

[0105] Specifically, after completing the adjustment of the first preset edge integrity, the central control unit re-determines whether the seal is qualified based on the adjusted first preset edge integrity, including: if the edge integrity is greater than the adjusted second preset edge integrity, the seal is determined to be qualified, and the seal unit is controlled to continue to operate using the current operating parameters; if the edge integrity is less than or equal to the adjusted second preset edge integrity, the seal is determined to be abnormal, and the operating parameters of each motor are adjusted based on the detail integrity.

[0106] Specifically, the central control unit is used to adjust the operating parameters of each motor based on the completeness of the details, including:

[0107] If the detail completeness is less than or equal to the preset detail completeness, adjusting the operating time of the moving motor 314 to a corresponding value based on the edge completeness;

[0108] If the detail completeness is greater than the preset detail completeness, the color extraction duration is adjusted to a corresponding value based on the detail completeness.

[0109] Specifically, the preset detail completeness is selected within the interval [0.65, 0.72].

[0110] Specifically, the color picking time is the length of time the seal stays on the ink pad 24 . It is understandable that the color picking time can be adjusted by adjusting the operating parameters of the seal motor 333 .

[0111] Specifically, the operating parameters of each motor are adjusted based on the detail completeness. When an abnormal seal application is determined, specific measures are further determined based on the determination of the seal's internal details. When the detail completeness is less than or equal to the preset detail completeness, most details are missing. This is because the seal is crooked, resulting in the camera being unable to fully capture the seal's image information. In this case, the operating time of the moving motor 314 is adjusted to ensure accurate seal application. When the detail completeness is greater than the preset detail completeness, a small amount of details are missing due to insufficient color extraction. In this case, the length of time the seal remains on the ink pad 24 is adjusted to ensure clear application, further improving seal application efficiency.

[0112] Specifically, the central control unit performs binarization processing on the stamp image information, and records the ratio of the number of pixels of the statistical stamp to the number of pixels of the pre-stored corresponding stamp as the detail completeness.

[0113] Specifically, the central control unit is configured to adjust the operating time of the moving motor 314 to a corresponding value based on the edge integrity, wherein the reduction in the operating time of the moving motor 314 is inversely proportional to the edge integrity.

[0114] In this embodiment, optionally,

[0115] Compare the edge integrity with a first preset edge comparison threshold and a second preset edge comparison threshold,

[0116] If the edge integrity is less than or equal to the first preset edge comparison threshold, the operating time of the moving motor 314 is adjusted to 0.76 times the initial operating time;

[0117] If the edge integrity is less than or equal to the second preset edge comparison threshold and greater than the first preset edge comparison threshold, adjusting the running time of the moving motor 314 to 0.84 times the initial running time;

[0118] If the edge integrity is greater than the second preset edge comparison threshold, the operating time of the moving motor 314 is adjusted to 0.95 times the initial operating time;

[0119] The first preset edge comparison threshold is 0.51, and the second preset edge comparison threshold is 0.65.

[0120] Specifically, the central control unit is used to adjust the color picking time to a corresponding value based on the detail completeness, wherein the increase in the color picking time is inversely proportional to the detail completeness.

[0121] In this embodiment, optionally,

[0122] Comparing the detail completeness with a first preset detail comparison threshold and a second preset detail comparison threshold;

[0123] If the detail completeness is less than or equal to the first preset detail comparison threshold, the color picking time is adjusted to 1.27 times the initial color picking time;

[0124] If the detail completeness is less than or equal to the second preset detail comparison threshold and greater than the first preset detail comparison threshold, the color picking time is adjusted to 1.19 times the initial color picking time;

[0125] If the detail completeness is greater than the second preset detail comparison threshold, the color picking time is adjusted to 1.13 times the initial color picking time;

[0126] The first preset detail comparison threshold is 0.8, and the second preset detail comparison threshold is 0.9.

[0127] Specifically, the central control unit adjusts the stamping time to 1.2 times the initial stamping time after completing the adjustment of the color picking time.

[0128] Specifically, the ink dwell time of the driving post 335 is the time the driving post 335 stays on the ink pad.

[0129] Specifically, after the central control unit completes the adjustment of the stamping time and the stamping unit completes the second stamping, it determines whether the stamping is qualified based on the re-acquired edge integrity, including: if the edge integrity is greater than the second preset edge integrity, the stamping is determined to be qualified, and the stamping unit is controlled to continue to operate using the current operating parameters; if the edge integrity is less than or equal to the second preset edge integrity and greater than the first preset edge integrity, whether the stamping is qualified is determined based on the operating time of the drive column 335; when the edge integrity is less than the first preset edge integrity, the control panel 1 issues an alarm message about insufficient ink pad.
