Description

Technical Field

[0001] The present invention relates to the technical field of picture making equipment, and in particular to a printing and cutting all-in-one machine and a picture making method. Background Art

[0002] The production of an image involves printing and cutting. With technological advancements, the variety of images is increasing, including both the subject matter and the shape of the image.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0020] In the description of the present invention, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0021] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0022] Reference Figures 1 to 4 The present invention discloses an all-in-one printer and cutter, comprising a base 100, a printing device 200, a cutting table 300, a camera positioning mechanism 400, a cutting mechanism, and multiple sets of paper pressing pin assemblies 600. The printing device 200 is mounted on the base 100 and is used to print an editing identification mark and a desired image on the surface of a paper and output the paper with the identification mark and image printed on it. The cutting table 300 is mounted on the base 100 and is located in front of the printing device 200. The cutting table 300 is used to absorb the paper output by the printing device 200. When the printing device 200 outputs the paper onto the cutting table 300, the cutting table 300 absorbs the paper.

[0023] The camera positioning mechanism 400 is arranged above the cutting table 300. The camera positioning mechanism 400 is used to locate the position of the identification mark and image to confirm the cutting path of the required picture; the cutting mechanism includes a driving group 500 and a carving knife 510 arranged on the output end of the driving group 500; multiple sets of paper pressing pin assemblies 600 are all arranged on the output end of the driving group 500, and multiple sets of paper pressing pin assemblies 600 are arranged around the carving knife 510. The driving group 500 drives the carving knife 510 and the multiple sets of paper pressing pin assemblies 600 to move in the front and back, left and right, and up and down directions. The multiple sets of paper pressing pin assemblies 600 are used to press the paper around the carving knife 510 on the cutting table 300 and can slide on the paper. The carving knife 510 is used to cut the surface of the paper on the cutting table 300 along the cutting path to obtain the required picture.

[0024] When the paper is adsorbed by the cutting table 300, the paper is laid flat on the cutting table 300, and the camera positioning mechanism 400 takes a picture of the paper to locate the position of the image and the identification mark on the paper. According to the specifications and requirements of the picture, the cutting path of the required picture is confirmed, and then the driving group 500 drives the engraving knife 510 and the multiple sets of paper pressing pin assemblies 600 to move synchronously, so that the engraving knife 510 moves along the trajectory of the cutting path, and the engraving knife 510 cuts the required picture on the surface of the paper. Since the multiple sets of paper pressing pin assemblies 600 move synchronously with the engraving knife 510, the multiple sets of paper pressing pin assemblies 600 press the paper near the engraving knife 510 on the cutting table 300, avoiding deformation and deviation of the paper caused by the force of the engraving knife 510 on the paper, so that the paper near the engraving knife 510 can also be kept stably laid on the cutting table 300, thereby ensuring the quality of the cut picture, high cutting accuracy and relatively smooth incision.

[0025] It is understandable that the printing device 200 can be a common device and no redundant introduction is given here. The printing device 200 prints an image and an identification mark on a paper and then transports the paper to the cutting table 300 .

[0026] Above the left and right sides of the cutting table 300 are two liftable pressure plates 900. When the two pressure plates 900 are lowered, they press the left and right ends of the paper against the cutting table 300, ensuring stable positioning of the paper. When the two pressure plates 900 are raised, they release the left and right ends of the paper, allowing the paper on the cutting table 300 to be removed and another paper to be moved onto the cutting table 300 and positioned opposite the two pressure plates 900. When the two pressure plates 900 are lowered again, the two pressure plates 900 can press the left and right ends of the other paper against the cutting table 300. The provision of the two pressure plates 900 ensures that the paper is stably positioned on the cutting table 300.

[0027] Reference Figure 3 In this embodiment, a lifting drive mechanism 311 is provided at each of the left and right ends of the cutting table 300. A pressure plate 900 is provided at the output end of each lifting drive mechanism 311. The two pressure plates 900 are located above the left and right ends of the cutting table 300, respectively. The lifting drive mechanism 311 is used to drive the pressure plates 900 toward or away from the cutting table 300. When the lifting drive mechanism 311 drives the pressure plates 900 toward the cutting table 300, the pressure plates 900 can press the left and right ends of the paper against the cutting table 300. The driving direction of the lifting drive mechanism 311 is perpendicular to the conveying surface of the conveyor 810.

[0028] Reference Figure 4 and Figure 5In some embodiments, the paper pressing pin assembly 600 includes a pin 610, an elastic member 620 and a ball 630. The upper end of the pin 610 is connected to the output end of the driving group 500, such as by using a fastener connection or a threaded structure connection, so that the pin 610 can be detachably connected to the output end of the driving group 500.

[0029] A receiving hole 611 is provided on the lower end surface of the pin 610, and the elastic member 620 and the ball 630 are both arranged in the receiving hole 611. The elastic member 620 drives the ball 630 to move toward the opening of the receiving hole 611, so that a part of the area of ​​the ball 630 extends outside the pin 610. The receiving hole 611 serves to receive the elastic member 620 and the ball 630, and the pin 610 serves to drive the elastic member 620 and the ball 630 to move. The ball 630 extends to the area outside the pin 610 to achieve the effect of pressing the paper against the cutting table 300.

[0030] The elastic member 620 is flexible and can adjust the height of the area where the ball 630 extends outside the pin 610, thereby providing a buffering effect. The ball 630 can rotate on the pin 610, that is, the ball 630 can roll on the paper, reducing the friction between the ball 630 and the paper.

[0031] Reference Figure 5 In some embodiments, the paper pressing pin assembly 600 further includes a limiting sleeve 640, the upper end of the limiting sleeve 640 is connected to the lower end of the pin 610, and the lower end of the inner wall of the limiting sleeve 640 is provided with an annular flange 641. The elastic member 620 and the ball 630 are first placed in the receiving hole 611 in sequence, and then the upper end of the limiting sleeve 640 is connected to the lower end of the pin 610. The flange 641 extends to the bottom of the receiving hole 611. The flange 641 can limit the ball 630 in the receiving hole 611, and a part of the area of ​​the ball 630 extends outside the pin 610, so that a part of the area of ​​the ball 630 can press the paper against the cutting table 300.

[0032] A gasket is disposed between the elastic member 620 and the ball 630. The gasket is capable of sliding within the receiving hole 611 along the depth direction of the receiving hole 611. The friction between the gasket and the ball 630 is low, thus preventing significant resistance to the rotation of the ball 630 caused by direct contact between the elastic member 620 and the ball 630. The inner diameter of the flange 641 is smaller than the outer diameter of the ball 630, and the outer surface of the annular flange 641 is relatively smooth. The flange 641 retains the ball 630 within the receiving hole 611, and the friction between the flange 641 and the ball 630 is low.

[0033] In some embodiments, the upper end of the limiting sleeve 640 is detachably connected to the lower end of the pin 610 to facilitate installation, removal, and maintenance of the ball 630, the elastic member 620, and the gasket. It is contemplated that the limiting sleeve 640 and the pin 610 can be detachably connected using fasteners or threaded connections.

[0034] Reference Figure 2 、 Figure 3 and Figure 6 In some embodiments, the printer-cutting machine further includes a bracket 800, which is disposed on the base 100 and in front of the printing device 200. The cutting table 300 is disposed at the rear end of the bracket 800. A conveyor path 810 is disposed at the front end of the bracket 800. The upper surface of the cutting table 300 and the upper surface of the conveyor path 810 are on the same plane. The printing device 200 conveys the paper on which the identification mark and image have been printed to the cutting table 300. The cutting mechanism cuts the required image from the paper, and then the paper and the image on the paper are conveyed forward through the conveyor path 810.

[0035] In some embodiments, the upper surface of the cutting table 300 and the upper surface of the conveying path 810 are lower in the front and higher in the back, that is, the cutting table 300 and the conveying path 810 are both inclined. Under the action of gravity, the paper is automatically transported forward and downward, and there is no need to set up a power mechanism to drive the paper to move.

[0036] The drive group 500 includes an X-axis drive mechanism, a Y-axis drive mechanism and a Z-axis drive mechanism. The driving directions of the X-axis drive mechanism, the Y-axis drive mechanism and the Z-axis drive mechanism are perpendicular to each other, thereby driving the engraving knife 510 to move in the front-back, left-right and up-down directions, that is, driving the engraving knife 510 to move in three-dimensional space, so that the engraving knife 510 can move along a variety of cutting paths, and then cut the surface layer of the paper on the cutting table 300.

[0037] The X-axis driving mechanism is arranged on the bracket 800. The driving direction of the X-axis driving mechanism is left and right and parallel to the conveying surface of the conveying path 810. The output end of the X-axis driving mechanism is connected to the Y-axis driving mechanism. The driving direction of the Y-axis driving mechanism is parallel to the conveying surface of the conveying path 810 and perpendicular to the driving direction of the X-axis driving mechanism. The output end of the Y-axis driving mechanism is connected to the Z-axis driving mechanism. The driving direction of the Z-axis driving mechanism is perpendicular to the conveying surface of the conveying path 810, and the driving direction of the Z-axis driving mechanism is perpendicular to the driving direction of the X-axis driving mechanism and the driving direction of the Y-axis driving mechanism. The output end of the Z-axis driving mechanism is connected to the engraving knife 510 and multiple sets of paper pressing pin assemblies 600.

[0038] The X-axis drive mechanism, the Y-axis drive mechanism, and the Z-axis drive mechanism drive the calibration block 700 and the cutting knife 510 along the X-axis, Y-axis, and Z-axis directions, respectively. The driving directions of the Z-axis drive mechanism and the lifting drive mechanism 311 are parallel to each other and perpendicular to the cutting table 300. The X-axis drive mechanism, the Y-axis drive mechanism, the Z-axis drive mechanism, and the lifting drive mechanism 311 can all be conventional cylinders, lead screws, or other common drive components.

[0039] Reference Figure 3 and Figure 4 The printer-cutting machine also includes a calibration block 700, which is detachably connected to the output end of the drive group 500. The drive group 500 is used to drive the calibration block 700 to move. Initially, the drive group 500 drives the calibration block 700 to rest on the cutting table 300. At this time, the engraving knife 510 and the paper pressing pin assembly 600 do not interfere with the cutting table 300. A right-angled surface 710 is provided on the calibration block 700. The paper is square and the engraving knife 510 has an origin position. When the engraving knife 510 is at the origin position, the calibration block 700 rests on the cutting table 300, and the paper is transported or placed on the cutting table 300. The right-angled surface 710 is in contact with the horizontal and vertical edges of the lower left corner of the paper. The two pressing plates 900 press the left and right ends of the paper on the cutting table 300. The position of the paper at this time is the reference position.

[0040] It should be noted that the right-angled surface 710 includes two right-angled planes, both of which are perpendicular to the cutting table 300 and are used to block the horizontal and vertical edges of the lower left corner of the paper, respectively. In this embodiment, one plane is parallel to the X-axis, and the other plane is parallel to the Y-axis.

[0041] The working method of the printer-cutting machine and the image production method performed using the printer-cutting machine are as follows: Edit the identification mark and the image to be printed, obtain electronic information of the image and the identification mark, and transmit the electronic information to the printing device 200; The calibration block 700 and the camera positioning mechanism 400 are used to obtain the identification mark coordinates B of the paper when the paper is in the standard position, and the initial cutting path is determined after the tape-out. The cutting knife 510 of the cutting mechanism moves to the origin, the printing device 200 prints an image and an identification mark on another sheet of paper and outputs the other sheet of paper to the cutting table 300, and the paper pressing pin assembly 600 blocks the other sheet of paper to stop the other sheet of paper on the cutting table 300; The cutting table 300 holds the paper in place, and the pressure plate 900 presses the paper against the cutting table 300. The camera positioning mechanism 400 takes a picture of another sheet of paper and obtains the identification mark coordinates b of the other sheet of paper. At this point, the difference between the executed cutting path of the engraving knife 510 and the initial cutting path is equal to the difference between the identification mark coordinates b and the identification mark coordinates B, thus obtaining the executed cutting path of the engraving knife 510. The driving group 500 drives the carving knife 510 to move along the cutting path, and the carving knife 510 cuts the surface layer of another paper, and the paper pressing pin assembly 600 around the carving knife 510 keeps the paper near the carving knife 510 pressed on the cutting table 300; Peel the cutout top layer off the other sheet of paper to get the desired image.

[0042] When the engraving knife 510 cuts the surface of the paper, the paper pressing pin assembly 600 around the engraving knife 510 keeps the paper near the engraving knife 510 pressed on the cutting table 300, which can avoid bending, deformation and deviation of the paper around the engraving knife 510 caused by the movement of the engraving knife 510, avoid curved cuts on the surface of the paper, ensure the accuracy of the engraving knife 510 in cutting the surface of the paper, and thus improve the quality of the cut image. The initial cutting path is determined by tape-out, and then the identification mark coordinates of the subsequent paper are obtained. The new execution cutting path is calculated by the change value of the identification mark coordinates. The method is relatively simple.

[0043] More specific steps are as follows: editing the identification mark and editing the image to be printed, obtaining electronic information of the image and the identification mark, and transmitting the electronic information to the printing device 200.

[0044] Initially, the calibration block 700 is installed on the output end of the drive group 500. The drive group 500 drives the calibration block 700, multiple sets of paper pressing pin assemblies 600 and the engraving knife 510 to move, and the engraving knife 510 moves to the origin position. At this time, the calibration block 700 is against the cutting table 300, and the printing device 200 prints an image and identification mark on a piece of paper and outputs a piece of paper to the cutting table 300, or manually places a piece of paper with printed image and identification mark on the cutting table 300. The cutting table 300 absorbs the paper, and the paper is flat on the cutting table 300. The position of the paper on the cutting table 300 is adjusted so that the horizontal and vertical edges of the lower left corner of the paper are attached to the right-angle surface 710, and then the two pressing plates 900 are lowered, that is, the pressing plates 900 move toward the cutting table 300 to press the left and right ends of the paper on the cutting table 300. At this time, the paper is in the standard position.

[0045] Then the camera positioning mechanism 400 takes a picture of the paper to obtain the origin coordinates A and the identification mark coordinates B, and designs or plans the initial cutting path of the engraving knife 510 based on the identification mark coordinates B and the required picture shape.

[0046] Next, the calibration block 700 is removed, and the engraving knife 510 is moved and operated along the initial cutting path to verify whether the desired image can be obtained. If the desired image can be obtained, the initial cutting path is recorded. If the desired image cannot be obtained, the above steps are repeated until the desired image can be verified and the initial cutting path is recorded. From installing the calibration block 700 on the output end of the drive assembly 500 to recording the initial cutting path, the step of using the calibration block 700 and the camera positioning mechanism 400 to determine the cutting path during the wafer production is completed.

[0047] When the printer-cutting machine subsequently prints the image repeatedly, the driving group 500 drives the multiple sets of paper pressing pin assemblies 600 and the engraving knife 510 to move, and the engraving knife 510 is reset to the origin corresponding to the origin coordinate A, and the multiple sets of paper pressing pin assemblies 600 are pressed against the cutting table 300. Then the printing device 200 prints the image and identification mark on another sheet of paper and outputs the other sheet of paper to the cutting table 300. The paper pressing pin assembly 600 blocks the other sheet of paper so that the other sheet of paper stops on the cutting table 300. The cutting table 300 absorbs the other sheet of paper, and the other sheet of paper is laid flat on the cutting table 300. The two pressing plates 900 move toward the cutting table 300 and press the left and right ends of the other sheet of paper on On the cutting table 300, the other sheet of paper is in a non-standard position at this time, and then the camera positioning mechanism 400 takes a picture of the other sheet of paper to obtain the identification mark coordinate b of the other sheet of paper. At this time, there is a difference between the identification mark coordinate b and the identification mark coordinate B. The difference between the execution cutting path of the engraving knife 510 and the initial cutting path is equal to the difference between the identification mark coordinate b and the identification mark coordinate B. The execution cutting path of the engraving knife 510 is obtained by the difference between the identification mark coordinate B and the identification mark coordinate b. Then the driving group 500 drives the engraving knife 510 to work along the execution cutting path to cut the surface layer on the other sheet of paper, and finally peels off the cut surface layer from the other sheet of paper to obtain the required picture.

[0048] It should be noted that when the calibration block 700 is against the cutting table 300, multiple sets of paper pressing pin assemblies 600 and engraving knives 510 must not interfere with the cutting table 300, otherwise any one or more of the paper pressing pin assemblies 600, the engraving knives 510 and the cutting table 300 may be damaged.

[0049] Reference Figures 1 to 3 As will be understood, the base 100 of the printer-cutting machine is provided with a housing 120. The base 100 and housing 120 enclose an inner cavity that accommodates the printing device 200, bracket 800, cutting table 300, camera positioning mechanism 400, cutting mechanism, and multiple sets of paper pressing pin assemblies 600. The front side of the housing 120 defines an outlet 121 that communicates with the inner cavity. Exit 121 faces the front end of the conveyor 810.
