Description

Technical Field

[0001] The invention relates to the technical field of seal management, and in particular to a seal control machine suitable for flip seals. Background Art

[0002] The printing control machine, also known as the seal machine, is a device that realizes the separation of people and seals by installing the physical seal into the chassis for locking. When stamping or maintenance is needed, the corresponding seal is called up through the operating platform for stamping operation. The setting of the printing control machine improves the reliability of seal storage, use approval, and post-use registration, avoids the occurrence of seal abuse, theft, and loss, reduces the dependence of enterprises on seal management personnel, and helps reduce the operating costs of enterprises for seal management positions.

[0003] However, traditional printing control machines are mostly suitable for seals that are dipped in ink through an oil printing pad. During the use of such printing control machines, since the oil printing pad is in an open state, the ink on the oil printing pad is easy to dry. Therefore, it is necessary to frequently open the chassis of the printing control machine to replace the ink, which increases the maintenance cost of the printing control machine; when a specific seal in the chassis needs to be taken out, in order to prevent the baffle from impacting the seal on the gripper, after the baffle is rotated, there is a large gap between the edge of the baffle on the side adjacent to the gripper and the gripper, and criminals can still take out the seal through the gap or destroy the arrangement of the seals in the chassis through the gap. The anti-theft effect of the baffle is insufficient, thereby affecting the normal use of the seal; after the seal is taken out and returned, the position and placement angle of the seal change. In this way, when the gripper grabs the seal and puts it back into the seal rack, it is easy to cause the seal and the installation hole of the seal rack to be incompatible, or the seal angle of the seal finally called to stamp changes, which increases the difficulty of returning the seal to its original position and affects the consistency of the seal stamping. Summary of the invention

[0004] Based on this, it is necessary to provide a printing control machine with good anti-theft effect and seal correction function that is suitable for flip seals to address technical problems such as high maintenance costs, insufficient baffle anti-theft effect and difficulty in returning the seal to its original position.

[0005] A printing control machine suitable for flip seals comprises a chassis, a frame housed in the chassis, a seal rack away from a main surface of the chassis and fixedly mounted on the frame, a main controller internally or externally arranged in the chassis, and a three-axis linkage seal taking mechanism controlled by the main controller to grab the flip seal.

[0006] A paper inlet for inserting or removing a document tray is provided at the bottom of the main surface of the chassis, and a seal removal opening and a safety door pivotally connected to the chassis for covering the seal removal opening are provided on one side of the chassis.

[0007] The seal rack is provided with a plurality of seal slots which are open to the main surface and the top surface of the chassis in parallel along the X-axis direction, and a seal sleeve with a flip seal at the bottom is correspondingly provided in each of the seal slots, a magnetic head is provided on the top of the seal sleeve, and an optical recognition point group for identifying different flip seals is provided on one side of the seal sleeve.

[0008] The three-axis linkage seal removal mechanism includes a first drive component with adjustable position along the Y-axis direction and a second drive component that slides with the first drive component. The second drive component is provided with a light sensor for identifying the optical recognition point group on the seal sleeve and a gripper that can be raised and lowered along the Z-axis direction and rotated in the XY plane, and at the end of which is provided with a seal removal head that engages with the magnetic head when powered on. The gripper is used to grab the seal sleeve and press the flip seal down to the file tray for stamping, and rotate the optical recognition point group on the seal sleeve to within the recognition range of the light sensor to correct the angle of the flip seal.

[0009] Four limiting grooves are evenly arranged on the circumference of the portion of the gripper where the second driving component is embedded. The second driving component is provided with a through hole which is connected to any of the limiting grooves when the gripper rotates. A marble which is used to cooperate with the limiting groove and has a diameter greater than the depth of the limiting groove is embedded in the through hole. The second driving component is also provided with an elastic member which passes through the through hole, abuts against the marble at one end and abuts against a set screw at the other end. The marble cooperates with the limiting groove to limit the rotation range of the gripper.

[0010] An anti-theft mechanism is provided in the chassis at a position adjacent to the seal dispensing port, and the anti-theft mechanism includes an L-shaped anti-theft door pivotally connected to the inner wall of the chassis, an anti-theft drive component for driving the L-shaped anti-theft door to rotate, and a sensor for detecting the opening and closing status of the security door. The free edge of the L-shaped anti-theft door is a serrated structure, and the first drive component is provided with a serrated bar that cooperates with the serrated structure, which are together used to prevent foreign objects from penetrating. When receiving the seal dispensing instruction sent by the main controller, the three-axis linkage seal dispensing mechanism grabs the seal sleeve that cooperates with the predetermined flip seal and moves the seal sleeve to the seal dispensing area adjacent to the seal dispensing port in the chassis. When receiving the security door opening information sent by the sensor, the anti-theft drive component drives the L-shaped anti-theft door to rotate in a direction close to the main surface of the chassis and separates the flip seal from the seal placement area in the chassis.

[0011] In one embodiment, the first driving assembly includes a first guide rod and a second guide rod respectively adjacent to two side surfaces of the chassis, arranged along the Y-axis direction and connected to the frame, a first driving motor and a second driving motor installed on the frame, and a cross bar slidably mounted across the first guide rod and the second guide rod, and the cross bar adjusts the position of the gripper along the X-axis direction under the joint action of the first driving motor and the second driving motor.

[0012] In one of the embodiments, a stopper for limiting the position of the crossbar is provided in the chassis, and the Y-axis distance from the stopper to the chapter frame is greater than the dimension of the second drive assembly along the Y-axis direction.

[0013] In one of the embodiments, a positioning piece is provided on the side of the inner cavity of the chassis where the seal removal port is located, and a plug-in that cooperates with the positioning piece is provided on the cross bar to limit the position of the cross bar during the seal removal operation.

[0014] In one of the embodiments, it also includes an image recognition sensor for reading the image content on the file tray and a fill light for providing illumination for the image recognition sensor. When the image recognition sensor recognizes the predetermined stamp information, the position information of the stamp information is sent to the main controller, and the main controller controls the three-axis linkage stamp removal mechanism to move the flip stamp to the position to be stamped.

[0015] In one of the embodiments, the second driving component is further provided with a height sensor for detecting and sending the height information of the top of the chapter sleeve to the main controller, and the main controller controls and adjusts the lifting height of the gripper.

[0016] In one of the embodiments, the second driving assembly is further provided with a baffle plate for separating the gripper and the main surface of the chassis.

[0017] In one of the embodiments, a mechanical lock and an electronic lock controlled by the main controller are provided at the junction of the free edge of the security door and the seal removal opening.

[0018] The printing control machine implemented in the present invention adopts a flip seal to replace the traditional seal, and the flip seal can be dipped into the ink without using an oil printing pad, thereby improving the problem of high equipment maintenance cost caused by frequent replacement of dried ink; by arranging an L-shaped anti-theft door at the seal taking port in the chassis, and arranging a serrated structure on the free side of the L-shaped anti-theft door and a serrated bar on the first driving component, while reserving a safe distance between the L-shaped anti-theft door and the gripper, it is difficult for foreign objects to pass through the broken line gap between the L-shaped anti-theft door and the serrated bar, thereby preventing lawbreakers from stealing the flip seal, thereby improving the anti-theft coefficient of the equipment; A light sensor is arranged on the second driving component. When the light sensor fails to recognize the information of the optical recognition point group, it determines that the angle of the seal sleeve on the gripper does not meet the requirements, thereby sending information to the main controller, which controls the rotation of the gripper to realize feedback adjustment of the seal sleeve angle until the optical recognition point group on the seal sleeve rotates to the recognition range of the light sensor, that is, it is determined that the seal sleeve angle meets the requirements, so as to facilitate stamping of documents on the file tray or accurately sending the seal sleeve into the designated seal position, realize the correction of the seal sleeve and the flip seal angle, thereby reducing the difficulty of returning the flip seal to its original position and improving the consistency of seal stamping.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0028] Please combine Figure 1 and Figure 2 The present invention provides a printing control machine suitable for flip seals with good anti-theft effect and a seal correction function. The printing control machine suitable for flip seals includes a chassis 100, a frame 200 accommodated in the chassis 100, a seal rack 300 away from the main surface of the chassis 100 and fixedly installed on the frame 200, a main controller 400 installed inside or outside the chassis 100, and a three-axis linkage seal taking mechanism 500 controlled by the main controller 400 to grab the flip seal 330.

[0029] The chassis 100 is used to separate the inside of the printing control machine from the outside environment, and to encapsulate each flip stamp 330, so as to limit the stamping operation of the document and the storage of the flip stamp 330 to the internal space of the chassis 100, and prevent the flip stamp 330 from being stolen by criminals, so as to improve the safety of the use of the flip stamp 330 and realize the efficient management of the flip stamp 330. A paper inlet for inserting or removing the file tray 110 is provided at the bottom of the main surface of the chassis 100, and a stamp removal port 120 and a safety door 130 pivotally connected to the chassis 100 for covering the stamp removal port 120 are provided on one side of the chassis 100. In this embodiment, the main surface of the chassis 100 refers to the side of the chassis 100 for placing the document to be stamped, that is, the side facing the user when in use. The document tray 110 is used to place documents to be stamped. Preferably, the document tray 110 is provided with a clip 111 for positioning the document, which is used to clamp the document to prevent the document from shifting during the stamping process, so that the seal is stamped at a designated position on the document to improve the reliability of the document stamping operation. A slide rail is provided on the inner surface of the bottom plate of the chassis 100, and a slider that cooperates with the slide rail is provided at the bottom of the document tray 110. The two slide together to limit the movement trajectory of the document tray 110. A locking piece for locking the document tray 110 is provided on the inner surface of the chassis 100 near the paper inlet, and a compression spring 140 is provided on the inner surface of the back of the chassis 100, that is, an inner surface of the chassis 100 away from its main surface. The compression spring 140 is compressed by the document tray 110 when the document tray 110 is inserted into the inner cavity of the chassis 100. When the locking piece releases the constraint on the document tray 110, the compression spring 140 provides elastic force for the restoration of the document tray 110. In this way, the document tray 110 bounces from the inner cavity of the chassis 100 to the outside through the paper inlet, so as to facilitate the placement of documents to be stamped or the removal of stamped documents.

[0030] When the user needs to stamp a large number of documents or needs to use stamps for other reasons, he can send instructions to the main controller 400 to control the three-axis linkage stamp taking mechanism 500 to grab a specific stamp to the stamp taking port 120, and then open the safety door 130 to take the corresponding stamp. In one embodiment, the outside of the chassis 100 is provided with a document table near the stamp taking port 120, and a camera 121 is provided above the document table for taking pictures of the stamp and the stamped document when taking the stamp, so that the stamp management personnel can review the stamped content. In one embodiment, the top of the chassis 100 is also provided with an environmental camera 150 for obtaining the facial and other body features of the stamping user, so as to facilitate tracing the corresponding responsible person after an accident occurs, and improve the safety, reliability and efficient management of document stamping.

[0031] The stamp rack 300 is used to place the flip stamp 330 that has not been stamped, that is, to realize the storage and positioning of multiple flip stamps 330, so as to facilitate the use of the corresponding flip stamp 330 in the stamping operation. Figure 3 and Figure 4 A plurality of stamp clamping positions 310 opening toward the main surface and the top surface of the chassis 100 are arranged side by side on the stamp rack 300 along the X-axis direction, and a stamp sleeve 320 with a flip stamp 330 at the bottom is correspondingly clamped in each stamp clamping position 310, and the outer surface of the stamp sleeve 320 has a structure adapted to the inner surface shape of the stamp clamping position 310, so as to facilitate hanging the stamp sleeve 320 on the stamp rack 300; a magnetic head 321 is provided on the top of the stamp sleeve 320, and an optical recognition point group 322 for identifying different flip stamps 330 is provided on one side of the stamp sleeve 320, so as to facilitate the three-axis linkage stamp taking mechanism 500 to accurately grasp the flip stamp 330, thereby improving the reliability of the stamping operation. In one embodiment, the optical recognition point group 322 includes three recognition holes distributed in sequence on one side of the chapter sleeve 320 along the Z-axis direction or along the X-axis direction. The three recognition holes are formed by a combination of a bright hole that can reflect infrared rays and a dark hole that cannot reflect infrared rays. After agreeing on the number corresponding to each hole, by adjusting the number and position of the bright holes and the dark holes, each optical recognition point group 322 corresponds to the number or other identity information of the chapter sleeve 320 to ensure the accuracy and reliability of chapter retrieval. It should be noted that the X-axis direction of this embodiment refers to the direction extending along the length of the paper inlet, the Y-axis direction refers to the direction from the back of the chassis 100 to the main surface of the chassis 100, and the Z-axis direction refers to the height direction along the chassis 100. The orientation descriptions in other embodiments can refer to this explanation and will not be repeated here.

[0032] For further information, see Figure 7In one embodiment, a shock-absorbing spring 210 is provided between the chapter rack 300 and the frame 200 to reduce the vibration of the chapter rack 300 when the chassis 100 is impacted by external force, thereby improving the reliability of the positioning of the chapter sleeve 320 and the flip chapter 330, facilitating the three-axis linkage chapter retrieval mechanism 500 to accurately grasp the flip chapter 330, and improving the success rate of chapter retrieval.

[0033] The main controller 400 is used to control the operation of each electrical device in the printing control machine when receiving external instructions, or to feedback and adjust the actions of other corresponding devices in the printing control machine when receiving signals sent by the internal devices of the printing control machine. In one embodiment, the main controller 400 is connected to the operating platform of the peripheral device through an HDMI data cable or other connecting cables, and can also be connected to the operating platform through Bluetooth or wireless signals. In this way, by manipulating the operating platform, corresponding instructions can be sent to the main controller 400 to control the operation of the printing control machine. Of course, a digital operation panel electrically connected to the main controller 400 can also be set on the chassis 100 to adjust the main controller 400 to achieve flexible control of the printing control machine.

[0034] The three-axis linkage chapter taking mechanism 500 is used to grab and move the chapter sleeve 320 to realize the taking of the flip chapter 330, and can also adjust the angle of the chapter sleeve 320 to realize the correction of the flip chapter 330. Figure 2 and Figure 5 The three-axis linkage chapter taking mechanism 500 includes a first driving component 510 whose position is adjustable along the Y-axis direction and a second driving component 520 that slides with the first driving component 510. The second driving component 520 is provided with a light sensor 521 for identifying the optical recognition point group 322 on the chapter sleeve 320, a gripper 522 that can be lifted and lowered along the Z-axis direction and rotated in the XY plane, and at the end of which is provided with a chapter taking head 523 that is attracted to the magnetic head 321, a lifting motor or a lifting driving cylinder (not shown) for driving the gripper 522 to lift and lower, and a rotating motor 524 for driving the gripper 522 to rotate. The gripper 522 is used to grab the chapter sleeve 320 and press the flip seal 330 down to the file tray 110 for stamping, and rotate the optical recognition point group 322 on the chapter sleeve 320 to within the recognition range of the light sensor 521 to correct the angle of the flip seal 330. A chapter removal head 523 is provided on the gripper 522. The chapter removal head 523 is a metal part. When it is close to the magnetic head 321 on the chapter sleeve 320, it is attracted to the magnetic head 321 to grab the chapter sleeve 320, thereby improving the grasping flexibility and taking efficiency of the inner chapter sleeve 320.

[0035] See also Figure 6Four limiting grooves 525 are evenly arranged in the circumference of the part of the gripper 522 embedded in the second driving component 520. The second driving component 520 is provided with a through hole 526 which is connected with any limiting groove 525 when the gripper 522 rotates. A marble 526a which is used to cooperate with the limiting groove 525 and has a diameter greater than the depth of the limiting groove 525 is embedded in the through hole 526. The second driving component 520 is also provided with an elastic member 526b which penetrates the through hole 526, one end of which abuts against the marble 526a and the other end of which abuts against the set screw 526c. The elastic member 526b can be a spring. The marble 526a cooperates with the limiting groove 525 to limit the rotation range of the gripper 522. Specifically, it can be agreed that the corresponding rotation angles of the gripper 522 when the four limit grooves 525 are set are 0 degrees, 90 degrees, 180 degrees and 270 degrees. When the gripper 522 rotates 90 degrees within a rotation stroke and the marble 526a slides into the limit groove 525, the marble 526a cooperates with the inner surface of the limit groove 525. At this time, the second drive component 520 acts on the gripper 522 through the mutual constraint of the limit groove 525 and the marble 526a, so that the gripper 522 is subject to greater resistance when it rotates further. In this way, under the limiting action of the limit groove 525, the gripper 522 rotates 90 degrees each time to facilitate the light sensor 521 to identify the optical recognition point group 322 on the chapter sleeve 320, thereby avoiding the difficulty in identifying the optical recognition point group 322 due to excessive rotation of the gripper 522 and the low efficiency of correcting the deviation of the gripper 522. When the optical sensor 521 fails to detect the corresponding optical identification point group 322 within one rotation stroke of the gripper 522, the rotary motor 524 drives the gripper 522 to rotate with a larger driving force, thereby overcoming the resistance of the limit groove 525 to the marble 526a and even the gripper 522, and entering the next rotation stroke to find the corresponding optical identification point group 322. It should be noted that Figure 6 It is only used to illustrate and facilitate the clear view of the matching relationship between the second drive assembly 520 and the gripper 522, wherein the dotted line portion is the matching shielding portion, and Figure 6 The specific structure of the second driving assembly 520 is not limited. Figure 5 .

[0036] Further, in one embodiment, the first driving assembly 510 includes a first guide rod 511 and a second guide rod 512, which are respectively adjacent to two sides of the chassis 100, arranged along the Y-axis direction and connected to the frame 200, a first driving motor 513 and a second driving motor 514 installed on the frame 200, and a cross bar 515 slidably mounted on the first guide rod 511 and the second guide rod 512, and the cross bar 515 adjusts the position of the gripper 522 along the X-axis direction under the joint action of the first driving motor 513 and the second driving motor 514. During the chapter taking operation, the first driving motor 513 and the second driving motor 514 work synchronously under the control of the main controller 400, and jointly drive the cross bar 515 to slide on the first guide rod 511 and the second guide rod 512, and the cross bar 515 is evenly stressed, thereby avoiding the problem of hysteresis of a part of the cross bar 515 caused by uneven stress at various places on the cross bar 515, improving the reliability of the movement of the cross bar 515, and facilitating the effective grasping of the flipped chapter 330.

[0037] In one embodiment, the second driving assembly 520 is further provided with a height sensor for detecting and sending the height information of the top of the chapter sleeve 320 to the main controller 400, and the main controller 400 controls and adjusts the lifting height of the gripper 522. Preferably, the height sensor is a laser rangefinder or an infrared rangefinder. Specifically, when it is necessary to put the flip seal 330 back into the corresponding seal position 310 on the seal rack 300, the height sensor sends a light signal to the top of the seal sleeve 320 on the gripper 522, and calculates the distance between the top of the seal sleeve 320 and the transmitting end of the height sensor by the time difference of the reflection of the light signal, and then transmits the distance value to the main controller 400. After receiving the distance value, the main controller 400 compares it with the preset standard distance value. If the measured distance value does not match the standard distance value, the main controller 400 will control the lifting motor to rotate forward or reverse to adjust the height of the gripper 522, thereby realizing the adjustment of the height of the seal sleeve 320 and the flip seal 330, so that when the gripper 522 grips the seal sleeve 320 close to the seal rack 300, the horizontal height of the structure cooperating with the seal position 310 on the seal sleeve 320 is consistent with the horizontal height of the seal position 310, so that the seal sleeve 320 can be smoothly inserted into the seal position 310 through the opening.

[0038] In one embodiment, a stopper 160 is provided in the chassis 100 for limiting the position of the crossbar 515, and the Y-axis distance between the stopper 160 and the chapter rack 300 is greater than the dimension of the second drive assembly 520 along the Y-axis direction. In other words, the stopper 160 is the farthest position from the main surface of the chassis 100 that the crossbar 515 can move along the Y-axis direction. In this way, the crossbar 515 can be prevented from impacting the chapter rack 300 when the main controller 400 delays in controlling the first drive motor 513 and the second drive motor 514, thereby ensuring the reliability of the hanging of the flip chapter 330 on the chapter rack 300. Please refer to Figure 7In one embodiment, the second driving assembly 520 is further provided with a baffle plate 527 for separating the gripper 522 and the main surface of the chassis 100. In this way, the printer malfunction caused by the criminal inserting the tool into the inner cavity of the chassis 100 from the paper inlet can be avoided, so as to facilitate the effective use of the printer.

[0039] See also Figure 7 and Figure 8 An anti-theft mechanism 600 is provided in the chassis 100 near the seal dispensing port 120. The anti-theft mechanism 600 includes an L-shaped anti-theft door 610 pivotally connected to the inner wall of the chassis 100, an anti-theft drive component 620 for driving the L-shaped anti-theft door 610 to rotate, and a sensor for detecting the opening and closing status of the security door 130. The output end of the anti-theft drive component 620 is hinged to the L-shaped anti-theft door 610. The free edge of the L-shaped anti-theft door 610 is a serrated structure. The first drive component 510 is provided with a serrated bar 516 that cooperates with the serrated structure, which are together used to prevent foreign objects from penetrating. When the three-axis linkage seal taking mechanism 500 receives the seal taking instruction sent by the main controller 400, it grabs the seal sleeve 320 matched with the predetermined flip seal 330 and moves the seal sleeve 320 to the seal taking area near the seal taking port 120 in the chassis 100. When the anti-theft drive component 620 receives the security door 130 opening information sent by the sensor, it drives the L-shaped anti-theft door 610 to rotate in the direction close to the main surface of the chassis 100 and separates the flip seal 330 from the seal placement area in the chassis 100. It should be noted that when the seal control machine works normally, that is, when the security door 130 is in a closed state, the L-shaped anti-theft door 610 is in an open state, that is, one wing plate of the L-shaped anti-theft door 610 is close to the inner wall of the chassis 100 to reserve space for the cross bar 515 and the second drive component 520 to pass through, so as to ensure the normal progress of the seal grabbing and stamping operations.

[0040] See also Figure 2In one embodiment, a mechanical lock 131 and an electronic lock 132 controlled by the main controller 400 are provided at the free side of the safety door 130 and the seal dispensing port 120. Specifically, when the user needs to take a specific flip seal 330, the user sends a command to the main controller 400, so that the main controller 400 controls the first drive motor 513, the second drive motor 514, the third drive motor for driving the second drive assembly 520 to slide on the crossbar 515, and the lifting motor to work respectively, so as to grasp the seal sleeve 320 on the seal rack 300, and move the seal sleeve 320 and the flip seal 330 to the vicinity of the seal dispensing port 120. After the flip seal 330 moves to the designated seal retrieval point, the main controller 400 controls the electronic lock 132 to open, and then the user opens the mechanical lock 131 on the security door 130 and pulls open the security door 130. In this case, the sensor detects that the security door 130 is open and sends a signal to the main controller 400. The main controller 400 controls the anti-theft drive 620 to operate, so that the anti-theft drive 620 drives the L-shaped anti-theft door 610 to deflect relative to the main surface of the chassis 100. The L-shaped anti-theft door 610 and the baffle plate 527 together surround the flip seal 330, separating the flip seal 330 from the other flip seals 330 in the chassis 100, and the serrated structure of the L-shaped anti-theft door 610 and the serrated bar 516 together form an anti-theft passage to prevent criminals from inserting tools into or foreign objects into the inner cavity of the chassis 100, so as to ensure the safety of the use of the flip seal 330. It should be noted that the mechanical lock 131 and the electronic lock 132 do not have to be used at the same time. In actual production, the mechanical lock 131, the electronic lock 132 and a combination of the two can be selected according to the specific needs of the user, which will not be described in detail here.

[0041] In one embodiment, a positioning member 170 is provided on the side of the inner cavity of the chassis 100 where the seal removal port 120 is located, and a plug-in 517 cooperating with the positioning member 170 is provided on the cross bar 515 to limit the position of the cross bar 515 during the seal removal operation. Furthermore, a bayonet is provided on the positioning member 170, and a sensing device is arranged in the bayonet. Thus, when the plug-in 517 on the cross bar 515 is not inserted into the bayonet, the level of the output of the sensing device to the main controller 400 remains unchanged, and the main controller 400 determines that the second driving component 520 has not moved the flip seal 330 to the designated chapter taking position. Thus, the main controller 400 continuously controls each motor to adjust the position of the flip seal 330 until the plug-in 517 on the cross bar 515 is inserted into the bayonet, and the output level of the sensing device changes. The main controller 400 determines that the flip seal 330 has reached the designated position, thereby controlling the lifting motor to lower the flip seal 330, and making the chapter taking head 523 leave the magnetic head 321 on the chapter sleeve 320 to loosen the flip seal 330, which is convenient for subsequent operations. It should be noted that the specific position of the positioning member 170 needs to be determined based on the size of the second drive assembly 520 and the height of the cross bar 515 along the Z-axis direction. When the plug-in 517 is inserted into the bayonet of the positioning member 170, the gripper 522 is facing the seal removal port 120. It will not be repeated here.

[0042] In one embodiment, the printing control machine further includes an image recognition sensor for reading the image content on the file tray 110 and a fill light for illuminating the image recognition sensor. When the image recognition sensor recognizes the predetermined stamping information, the position information of the stamping information is sent to the main controller 400, and the main controller 400 controls the three-axis linkage seal taking mechanism 500 to move the flip seal 330 to the position to be stamped. In this way, even if the document is placed upside down in the file tray 110 or the stamping position on the document changes, the image recognition sensor can always recognize the stamping position, so that the main controller 400 controls the gripper 522 to stamp the flip seal 330 at the specified position, realizing the intelligent stamping operation.

[0043] The printing control machine of the present invention adopts a flip seal 330 to replace a traditional seal, and the flip seal 330 can be dipped into ink without using an oil printing pad, thereby improving the problem of high equipment maintenance cost caused by frequent replacement of dried ink; by arranging an L-shaped anti-theft door 610 at the seal taking port 120 in the chassis 100, and arranging a serrated structure on the free side of the L-shaped anti-theft door 610 and a serrated bar 516 on the first driving component 510, while reserving a safe distance between the L-shaped anti-theft door 610 and the gripper 522, it is difficult for foreign objects to pass through the broken line gap between the L-shaped anti-theft door 610 and the serrated bar 516, thereby preventing lawless elements from stealing the flip seal 330, thereby improving the anti-theft coefficient of the equipment; by A light sensor 521 is provided. When the light sensor 521 fails to recognize the information of the optical recognition point group 322, it determines that the angle of the chapter sleeve 320 on the gripper 522 does not meet the requirement, thereby sending information to the main controller 400. The main controller 400 controls the rotation of the gripper 522 to implement feedback adjustment of the angle of the chapter sleeve 320 until the optical recognition point group 322 on the chapter sleeve 320 rotates to within the recognition range of the light sensor 521, i.e., it is determined that the angle of the chapter sleeve 320 meets the requirement, so as to facilitate stamping of documents on the document tray 110 or accurately delivering the chapter sleeve 320 into the designated seal position 310, thereby realizing the correction of the angles of the chapter sleeve 320 and the flip seal 330, thereby reducing the difficulty of returning the flip seal 330 to its original position and improving the consistency of stamping.
