The pallet body 201 may be square, or may be other shapes, and may be in a net structure, so that the weight of the pallet body 201 may be reduced. In this embodiment, as shown in fig. 2, a fixing groove 20 for placing an inkpad cartridge is provided on a pallet body 201, and the fixing groove 20 is recessed downward in a shape matching the shape of the inkpad cartridge. The connection mode of the pallet body 201 and the box 10 is not limited, for example, a guide rail is arranged at the bottom of the box 10, and two sides of the pallet body 201 along the length direction are clamped into the guide rail, so that the pallet body 201 can slide relative to the guide rail; of course, the supporting plate body 201 can be provided with balls or rollers, so that the sliding of the supporting plate body 201 relative to the guide rail is easier and smoother; the guide rail can also be arranged on the supporting plate body 201, the guide rail matched with the guide rail on the supporting plate body 201 is arranged on the box body 10, the two guide rails are mutually matched to realize the sliding connection of the supporting plate body 201 and the box body 10, and the ball or the roller is arranged between the two guide rails so as to improve the sliding fluency between the two guide rails. Of course, other structures may be adopted for the sliding connection between the pallet body 201 and the case 10, as long as the pallet body 201 can slide relative to the case 10. Specifically, in this embodiment, the sliding rail 101 is disposed on the box 10, the width of the sliding rail 101 is consistent with the width of the pallet body 201, sliding grooves are disposed on two sides of the sliding rail 101 along the length direction, edges of two sides of the pallet body 201 along the length direction respectively extend into the sliding grooves, a plurality of balls are disposed on two sides of the pallet body 201 at intervals, and the balls slide in the sliding grooves, so that the pallet body 201 is slidably connected to the sliding rail 101, and further sliding of the pallet body 201 relative to the box 10 is achieved.

In one embodiment, the electrostatic generating unit includes a power source, a voltage transformation module, and an electric field generating module. The voltage transformation module is electrically connected with the power supply and is used for boosting the input voltage of the power supply so that the voltage input to the electric field generation module can generate an electrostatic field. Specifically, the voltage transformation module boosts the input voltage to a preset threshold value and outputs the boosted voltage; the electric field generating module is electrically connected to the voltage transformation module, and the electric field generating module is used for generating an electrostatic field, so that the electrostatic field is generated on the pallet body 201. Wherein, the pallet body 201 is made of metal material, the static electricity generating unit is fixedly connected on the pallet body 201, and the electric field generating module is electrically connected with the pallet body 201, so that the pallet body 201 and the electric field generating module can generate electrostatic fields simultaneously. In the embodiment, the power supply adopts a dry battery, the output voltage of the power supply is 1.5V, and the output voltage of the transformation module is between 15 and 36V. Specifically, the voltage transformation module only needs to boost the output voltage to 15V, so that the electrostatic field can be generated on the electrostatic generation module. By adopting the mode, on one hand, the electrostatic field can be generated by only one dry battery without accessing excessive power supply, and on the other hand, the input voltage on the electrostatic generation module is boosted to 15V through the voltage transformation module, so that the electrostatic field generator does not harm human body and has the characteristics of safe and reliable use. The electrostatic generating unit capable of generating 15V safe direct current voltage is connected with the supporting plate body 201, so that an electrostatic field is generated on the supporting plate body 201, and paper to be stamped is adsorbed on the supporting plate body 201. When the seal is finished, the static electricity is eliminated, and the static electricity on the surface of the supporting plate body 201 can be removed only by grounding the surface of the supporting plate body 201 through a switch and discharging the static electricity to the ground through a ground wire, so that the paper is separated from the supporting plate body 201.

In other embodiments, the pallet mechanism 20 further includes a pallet 202 having a plurality of touch areas on the pallet 202 and a plurality of touch areas on the pallet that are illuminated in response to a touch. Specifically, the pallet 202 includes a touch display screen on which a touch area is provided. In this embodiment, the touch display screen is a capacitive screen. For the structure of the supporting plate, the capacitive screen can be only one and is fixedly connected to the supporting plate body; the capacitive screen can also be a plate body for supporting the capacitive screen, the capacitive screen is fixed with the plate body, and the plate body is fixed with the supporting plate body. Of course, the control of the touch area is realized by a control program in a computer connected with the printer. Because the pallet 202 is a capacitive screen, when an operator's finger touches the capacitive screen, the user and the surface of the capacitive screen form a coupling capacitor due to the human body's electric field, and the capacitor is a direct conductor for high frequency current, so that the finger draws a small current from the contact point on the capacitive screen. The current flows from the electrodes at the four corners of the capacitive screen respectively, and the current flowing through the four electrodes is proportional to the distances from the finger to the four corners, and an external computer obtains the accurate position of the touch point through accurate calculation of the four current ratios. Thus, by providing the pallet 202 as a capacitive screen, by pressing the stamping position placed on the sheet to be stamped on the capacitive screen, the pressed position is lit. In the present embodiment, the pressed position is caused to appear as a stamp image centered on the pressed point by a control program in a computer. Because the pallet 202 is a capacitive screen, the brightness is high and can be clearly seen through the paper. If the user determines that the position is the position to be truly printed, the user only needs to check the position in the seal image area; if the initial position is found to be not right, the image appearing at a point outside the area disappears, and then the stamping position is specified again.

As shown in fig. 1-7, the present invention also provides a printer comprising the pallet mechanism 20 as described above. In this technical scheme, through setting up the layer board mechanism 20 in the above-mentioned scheme in the printer, when using the printer, produce electrostatic field on layer board body 201 through the static electricity generation unit in layer board mechanism 20 to the paper that will stamp adsorbs with fixed paper, has improved the fixed convenience of paper on the one hand, on the other hand, makes the paper fix on layer board body 201, is difficult for blowing off when stamping, has improved the accuracy of stamping.

In one embodiment, the printer further comprises a stamping mechanism 30 for clamping the stamp and driving the stamp 40 to move, wherein the stamping mechanism 30 is slidably connected to the box 10 and located above the supporting plate mechanism 20, and the stamping mechanism 30 can move in a first direction and a second direction of the box 10 relative to the supporting plate mechanism 20, and the first direction and the second direction are perpendicular. The first direction may be a left-right direction in fig. 1, and the second direction may be a front-rear direction in fig. 1. By slidably connecting the stamping mechanism 30 with the case 10, the stamping mechanism can drive the stamp 40 to move to the desired stamping position. The stamping mechanism 30 is disposed above the tray mechanism 20 so as to stamp the paper placed on the tray mechanism 20. Of course, in other embodiments, the stamping mechanism 30 may be disposed at other positions as long as the stamp 40 can be dropped onto the sheet on the tray mechanism 20 to be stamped. Of course, the stamping mechanism 30 is arranged above the supporting plate mechanism 20, which is beneficial to saving the whole occupied space of the stamping mechanism 30 and the supporting plate mechanism 20, thereby simplifying the structure of the printer. The stamping mechanism 30 is arranged in a manner that the stamping mechanism can slide in the first direction and the second direction of the supporting plate, so that the stamping mechanism 30 can move to any position on the supporting plate mechanism 20, the stamping of paper to be stamped on the supporting plate mechanism 20 can be realized, and the universality and convenience of the use of the printer are improved. The specific structure of the seal mechanism 30 is not limited as long as it can be lifted from one position and then dropped into another position. That is, when stamping the paper, the stamping mechanism 30 can drop into the position of the inkpad box with the stamp 40 downwards to dip in the inkpad, lift the stamp 40, and then drop the stamp 40 into the position to be stamped on the paper, so as to realize automatic stamping of the paper.

Specifically, the stamping mechanism 30 can be used for realizing the switching between the inkpad box and the position to be stamped through a sliding rail and realizing the up-and-down movement of the stamp through a push type structure, so as to dip the inkpad and stamp the position to be stamped. Of course, other configurations may be used.

For example, in one embodiment, the stamping mechanism 30 includes a frame 301 slidably connected to the case 10, a lifting assembly 302 for driving the stamp to lift and switch positions, and a cantilever 303 for fixing the stamp. Specifically, the frame 301 is slidably connected to the case 10; the lifting assembly 302 is connected to the frame 301; the cantilever 303 is connected to the lifting assembly 302, and the lifting assembly 302 drives the cantilever 303 to move from the first position to the second position. Wherein, the relative forms of the first position and the second position are not limited, and the first position and the second position can be two different positions in the same plane; but may also be in different positions in different planes. For example, in the present embodiment, the first position may be a position where an ink pad is located, and the second position may be a position to be stamped on a sheet to be stamped on the tray mechanism 20. The inkpad box may be placed at the same height as the paper on the tray mechanism 20, or may be placed at a different height from the paper on the tray mechanism 20, depending on the requirements.

In this embodiment, the frame 301 includes a fixing plate extending in the vertical direction and a fixing plate extending in the first direction, and the two fixing plates are fixed to each other to form a right angle structure. The lifting unit 302 may be configured to move up and down in the vertical direction, or may be configured to perform an arc movement from the first position to the second position.

In some embodiments, the lifting assembly 302 includes a driving member 3021, a driving wheel 3022, and a linkage, where the driving member 3021 is fixedly connected to the frame 301; the driving wheel 3022 is rotatably connected to the driving member 3021, and a position where the driving wheel 3022 is connected to the driving member 3021 is deviated from a central axis of the driving wheel 3022; the linkage is connected to the drive wheel 3022, and the cantilever 303 is connected to the linkage; the driving wheel 3022 drives the linkage to switch between the first position and the second position.

The driving member 3021 may be a motor, the driving wheel 3022 is connected to an output shaft of the motor, the driving wheel 3022 is an eccentric wheel, that is, a position where the driving wheel 3022 is connected to the output shaft of the motor deviates from a central axis of the driving wheel 3022, and the driving wheel 3022 is driven to rotate by the motor. The driving wheel 3022 drives the linkage to switch between the first position and the second position, so that the cantilever 303 is switched between the first position and the second position.

Specifically, the linkage includes a first link 3023, a second link 3024, a third link 3026, and a fourth link 3027, wherein one end of the first link 3023 is slidably hinged to an edge of the driving wheel 3022, and one end of the first link 3023 is away from the driving element 3021; one end of the second link 3024 is rotatably connected to the other end of the first link 3023; one end of the third connecting rod 3026 and the other end of the second connecting rod 3024 are respectively fixed on a rotating shaft 3025, and the rotating shaft 3025 is rotatably connected with the frame 301; one end of the fourth link 3027 is rotatably connected to the chassis 301, one end of the fourth link 3027 is close to the driving element 3021, the other end of the third link 3026 and the other end of the fourth link 3027 are respectively connected to the cantilever 303, and a portion of the cantilever 303 extends in the direction of the pallet mechanism 20.

In the above technical solution, the driving wheel 3022 is driven to rotate by the motor, and since one end of the first link 3023 is slidably hinged to the edge of the driving wheel 3022, when the driving wheel 3022 rotates, one end of the first link 3023 is pulled by the driving wheel 3022, so that one end of the first link 3023 is driven by the driving wheel 3022 to move. Since the other end of the first link 3023 is rotatably connected to one end of the second link 3024, one end of the second link 3024 is rotated back and forth about the hinge shaft by the force of the first link 3023, thereby rotating the rotary shaft 3025 connecting the second link 3024 and the third link 3026 back and forth about its own axis. Because the other end of the third link 3026 and the other end of the fourth link 3027 are rotatably connected to the cantilever 303, when the rotating shaft 3025 of the third link 3026 rotates, the other end of the third link 3026 is driven to rotate back and forth, so that the cantilever 303 moves back and forth along an arc. When the driving wheel 3022 rotates to a position where the edge thereof is farthest from the output shaft of the motor and corresponds to one end of the first link 3023, the cantilever 303 is positioned at the first position and can be brought into contact with the inkpad box; when the capstan 3022 rotates to a position on its edge closest to the output shaft of the motor corresponding to one end of the first link 3023, the cantilever 303 is in the second position, and the stamp on the cantilever 303 stamps the paper. In this embodiment, the cantilever 303 has a T-shaped member, two ends of the top of the T-shaped member are rotatably connected to two ends of the third link 3026 and the fourth link 3027, respectively, and the bottom end of the T-shaped member is used for clamping the stamp.

Of course, other structures may be adopted for the lifting assembly, for example, by connecting an eccentric driving wheel 3022 with the output shaft of the motor, one end of a connecting rod is hinged with the frame 301, the other end of the connecting rod is connected with the frame 301 through a spring, one end of the cantilever 303 is fixed with the other end of the connecting rod, and the middle part of the connecting rod abuts against the peripheral edge of the driving wheel 3022. The link is driven to rotate by the rotation of the driving wheel 3022, and the other end of the link is pulled up by the restoring force of the spring. By this structural form, the cantilever 303 moves up and down, and thus the stamp is lifted and lowered. The seal can be moved from the first position to the second position by sliding the frame 301 with the guide rail.

Further, the cantilever 303 includes a clamping portion 3031, and the clamping portion 3031 is provided with a receiving groove, and a portion of the stamp 40 is detachably clamped in the receiving groove. The clamping portion 3031 of the cantilever 303 may be connected to the other body of the cantilever 303 by welding or may be integrally formed. Specifically, the width of the opening of the accommodating groove is smaller than the width of the groove body of the accommodating groove, the thinnest part of the seal is clamped at the opening of the accommodating groove, and a bolt is arranged on the clamping part 3031 and used for propping against the top of the seal 40, so that the limit of the seal in the axial direction is realized.

In some embodiments, the case 10 is provided with a first rail 102 extending along a first direction of the case 10 and a second rail 103 extending along a second direction of the case 10, and the stamping mechanism 30 is slidably connected to the first rail 102 and the second rail 103. Specifically, the top of the frame is slidably connected with the first guide rail 102 and the second guide rail 103 respectively, so that the stamping mechanism 30 slides along the first direction and the second direction of the box 10, the stamp can be located at any position on the paper, and stamping can be performed at any position required by the paper by the stamp.

In one embodiment, the printer further includes a partition 104, the partition 104 is connected to the box 10 and divides the cavity in the box 10 into a first space and a second space, a gap is provided between the bottom of the partition 104 and the bottom surface of the box 10, the stamping mechanism 30 and the pallet mechanism 20 are disposed in the first space, and at least a portion of the pallet body 201 is movable from the first space to the second space through the gap between the partition 104 and the bottom surface. By arranging a partition plate 104 in the box 10 and dividing the inward inner cavity into a first space and a second space, when the paper needs to be stamped, the supporting plate body 201 slides into the second space, and after the staff places the paper on the supporting plate body 201, the supporting plate body 201 moves back into the first space for stamping operation.

As shown in fig. 8, an embodiment of the present invention further provides a control method of a printer, where the printer includes a pallet mechanism for carrying a sheet to be stamped, and a stamping mechanism for driving a stamp to move; the control method of the printer comprises the following steps: step S10, if the supporting plate mechanism receives touch operation, controlling to confirm the touch position on the supporting plate mechanism; s20, controlling the pallet mechanism to generate an electrostatic field so as to adsorb paper on the pallet mechanism; and S30, controlling the stamping mechanism to drive the stamp to move so that the stamping force acts on the position, needing stamping, of the paper, and the position, needing stamping corresponds to the touch position.

In the scheme, the stamping of the paper to be stamped is realized through the control method of the printer, on one hand, the position to be stamped is convenient to determine, so that the stamping position accuracy is improved, on the other hand, static electricity is generated on the supporting plate mechanism to adsorb the paper to be stamped, so that the paper fixing convenience is improved, and meanwhile, the stamping position accuracy is also improved.

In one embodiment, if the touch operation is received on the pallet mechanism, the step of confirming the touch position includes: and controlling to lighten the touch control position on the supporting plate mechanism. The touch control position on the supporting plate mechanism is lightened to seal the lightened position, so that the accuracy of the seal position is improved.

In one embodiment, the step of controlling the stamping mechanism to drive the stamp to move so that the stamping force acts on the position, needing stamping, of the paper, and the position, needing stamping corresponds to the touch position further comprises: the control is used for releasing the electrostatic field on the supporting plate mechanism, and the paper is separated from the supporting plate mechanism. In the embodiment, the electrostatic generating unit enables the capacitive screen on the supporting plate body to generate an electrostatic field, so that the capacitive screen can adsorb paper; of course, the electrostatic field on the capacitive screen on the pallet body is released by grounding the electrostatic generating unit, so that the paper is separated from the capacitive screen.

The control method of the printer comprises the following specific steps:

when the printing control computer receives the printing application instruction, the printing control computer obtains the number of times of printing, marks the number of times of printing as B, and assigns the number B to the counter. The control unit opens the box door by sending an instruction for opening the box door by the control computer. The computer sends out a pallet moving-out instruction, and the control unit controls the pallet body on the pallet mechanism 20 to move from the first space to the second space of the box body. The sheet to be stamped is placed on a capacitive screen on a pallet. The method comprises the steps that a position to be stamped on a piece of paper is touched by hand, a control unit controls the position to be stamped on a capacitive screen to be lighted, a stamp image taking a point contact as a center appears on the capacitive screen, whether the lighted position is the position to be stamped or not is judged by a worker, if yes, the position is touched again, and the position to be stamped is determined and is always in a lighted state. If not, clicking is performed at a position other than the position just touched, and the bright seal image disappears. In the process, the electrodes at the four corners of the capacitive screen are combined into coordinates of touch points according to the horizontal and longitudinal distances and stored in a memory, and the whole process realizes operation through lambda expression.

After the coordinate points of the stamping positions are stored, sending an instruction for closing the box door by the computer, judging whether the box door of the printer is closed or not, if not, judging whether the box door is closed again if the box door is not closed but the set time is not exceeded; the case door is not closed, and the time when the case door is not closed exceeds a set time, the case door is closed and the printing operation is ended. When the box door is judged to be closed, the control unit controls the static electricity generating unit to generate an electrostatic field on the capacitive screen, and simultaneously controls the stamping mechanism to dip inkpad and reset. After an electrostatic field is generated on the capacitive screen, the paper to be stamped is adsorbed on the electrostatic field, and the supporting plate body is reset into the first space. The control unit controls the seal clamped on the seal mechanism to move to the position needing to be sealed according to the seal position stored in the memory, and then the seal is lifted up quickly after the seal moves down. After the control unit controls the supporting plate body to move to the second space again, the static electricity generating unit is controlled to release static electricity, and at the moment, the paper is separated from the supporting plate. The control unit controls the opening of the box door, and the stamping numerical value on the counter is B-1. The cycle is thus completed until the stamping value b=0 on the counter.
