Description

Technical Field

[0001] The present invention relates to the field of printing technology, and particularly to a packaging printing method and system. Background Art

[0002] In the field of packaging printing, different post-press processing methods are usually adopted to improve the appearance quality and meet the usage requirements. For packaging prototype printing or small-batch production, the existing method still uses manual alignment to achieve overprinting: first, digital printing is completed by a printer, and then varnish is printed in a specified area by a desktop flatbed printer. When printing, trimming and punching alignment are required. However, the existing method aligns the printed sheets through the registration marks and lines on the transparent plate of the punching machine. Such repeated alignment may take a long time, with low efficiency, and it is easy to have alignment deviation, resulting in a decline in printing quality. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. For this purpose, the present invention provides a packaging printing method and system to solve the technical problem of how to improve the efficiency and quality of packaging printing.

[0004] In a first aspect, the present invention provides a packaging printing method, including:

[0005] Mark the paper to be printed, wherein the marked content includes cutting marks and registration marks;

[0006] Obtain cutting position data according to the cutting marks and registration marks;

[0007] Perform laser cutting of the edges and positioning holes on the paper to be printed according to the cutting position data;

[0008] Place the paper to be printed at a corresponding preset printing position according to the position of the positioning holes for printing in a specified area.

[0009] In a technical solution of the above packaging printing method,

[0010] The obtaining of the cutting position data according to the cutting marks and registration marks includes: capturing the cutting marks and registration marks based on a vision detection system and generating corresponding cutting position data in the vision detection system. Capturing the cutting marks and registration marks directly through the vision detection system can directly obtain the cutting position data, saving a large amount of time for manually aligning the printed paper, improving the efficiency of the overall printing process, and through the position capture by the vision detection system, the manual vision alignment error can be effectively reduced, improving the alignment accuracy, thus being beneficial to improving the printing quality.

[0011] Specifically, the visual detection system captures the cutting marks and registration marks, and generates corresponding cutting position data in the visual detection system, including:

[0012] The visual detection system captures the cutting marks and registration marks to obtain the coordinate positions of the cutting marks and registration marks in the visual detection system;

[0013] According to the coordinate positions of the cutting marks in the visual detection system, the cutting position data of the side lines are obtained;

[0014] According to the coordinate positions of the registration marks in the visual detection system and the fixed relative position relationship with the positioning holes, the cutting position data of the positioning holes are obtained.

[0015] Since the paper to be printed has cutting marks and registration marks, the coordinate positions of the marks in the visual detection system can be directly obtained by visual capture. At the same time, since the positions of the positioning holes and the registration marks are relatively fixed, as long as the coordinates of the registration marks and their relative position relationship with the positioning holes are obtained, the cutting position data of the positioning holes in the visual detection system can be obtained.

[0016] In a technical solution of the above packaging and printing method,

[0017] The laser cutting of the side lines and positioning holes of the paper to be printed according to the cutting position data includes:

[0018] Compensate the cutting position data to obtain the corresponding actual cutting position data in the laser cutting system;

[0019] According to the actual cutting position data, laser cut the side lines and positioning holes of the paper to be printed.

[0020] Based on the laser cutting technology, the paper cutter and punching machine can be directly replaced for precise cutting and punching. Among them, there may be a certain deviation between the positions in the laser cutting system and the visual detection system, and certain data compensation for the deviation is required to obtain the corresponding actual cutting position data in the laser cutting system.

[0021] Specifically, the compensation of the cutting position data to obtain the corresponding actual cutting position data in the laser cutting system includes:

[0022] Obtain the position deviation amount between the laser cutting system and the visual detection system;

[0023] Based on the position deviation amount, compensate the cutting position data generated in the visual detection system to obtain the corresponding actual cutting position data in the laser cutting system.

[0024] Among them, obtaining the position deviation amount between the laser cutting system and the vision detection system includes:

[0025] Obtaining the origin coordinates of the vision detection system and the laser cutting system in the same coordinate system;

[0026] Performing a difference calculation on the origin coordinates of the vision detection system and the laser cutting system to obtain the position deviation amount between the laser cutting system and the vision detection system.

[0027] Compensating the cutting position data generated in the vision detection system based on the position deviation amount to obtain the corresponding actual cutting position data in the laser cutting system, including:

[0028] Superimposing the position deviation amount on the cutting position data to obtain the corresponding actual cutting position data in the laser cutting system.

[0029] The relative positions between the respective coordinates in the laser cutting system and the vision detection system are consistent, but there is a certain deviation between the origin of the coordinate systems of the two, resulting in this deviation between each corresponding coordinate of the two. Therefore, as long as this origin deviation is superimposed on the coordinate positions of each mark obtained in the vision detection system, the actual corresponding position coordinates in the laser cutting system, that is, the actual cutting position data, can be obtained.

[0030] In a technical solution of the above packaging and printing method,

[0031] According to the position of the positioning hole, placing the paper to be printed on the corresponding preset printing position for printing in a specified area, including:

[0032] Aligning the positioning hole with the corresponding positioning mechanism on the printing master plate;

[0033] Placing the paper to be printed on the printing master plate according to the aligned position so that the paper to be printed is placed on the corresponding preset printing position;

[0034] Performing UV printing on the specified area of the paper to be printed.

[0035] Based on the above steps, placing the paper to be printed with holes on the printing master plate, and the positioning mechanism on the printing master plate corresponds to the position of the positioning hole. Therefore, by placing the paper through the positioning hole at the corresponding position, UV varnishing printing on the specified area can be directly started. Since the positioning holes of the laser cutting are precise, the accuracy of its position on the master plate is improved, thereby improving the accuracy of varnishing printing on the specified area and improving the printing quality.

[0036] In a second aspect, the present invention provides a packaging and printing system, including:

[0037] A marking device configured to mark a paper to be printed, wherein the marking content includes cutting marks and registration marks;

[0038] A visual detection system configured to obtain cutting position data according to the cutting marks and registration marks;

[0039] A laser cutting system configured to perform laser cutting on the edges and positioning holes of the paper to be printed according to the cutting position data;

[0040] A printing device having a preset printing position, and the paper to be printed is placed on the preset printing position according to the positions of the positioning holes, so that the printing device performs printing in a specified area.

[0041] In a technical solution of the above packaging and printing system,

[0042] The visual detection system is configured to capture the cutting marks and registration marks, generate corresponding cutting position data and send it to the laser cutting system. By using the mark capture function of the visual detection system, the marks are acquired and corresponding cutting position data is generated in the system and then sent to the laser cutting system for cutting. In the present invention, the visual system adopts a CCD visual system.

[0043] In a technical solution of the above packaging and printing system,

[0044] There is a fixed relative position relationship between the registration marks and the positioning holes, and the visual detection system is configured to obtain the cutting position data of the positioning holes according to the coordinate positions of the registration marks and the fixed relative position relationship. The position relationship between the registration marks and the positioning holes is fixed. Therefore, as long as the registration marks are captured in the visual detection system, the position of the positioning holes in the visual detection system can be obtained.

[0045] In a technical solution of the above packaging and printing system,

[0046] The laser cutting system is configured to compensate the cutting position data from the vision detection system to obtain the actual cutting position data. There is a certain positional deviation between the laser cutting system and the vision detection system. After corresponding compensation for the position in the vision detection system, the actual cutting position can be obtained for precise cutting. In the present invention, the laser cutting system and the vision detection system have a fixed amount of positional deviation; the laser cutting system is configured to compensate the cutting position data generated in the vision detection system according to the amount of positional deviation to obtain the actual cutting position data. The relative positions of the respective markers and the origin in each coordinate system are consistent. Therefore, as long as the deviation amount between the corresponding coordinates is obtained, the actual cutting position can be obtained. Further, the laser cutting system includes a laser, and the laser is configured to perform laser cutting edges and positioning holes on the paper to be printed according to the actual cutting position data, and finally the laser performs cutting edges and punching on the paper.

[0047] In a technical solution of the above packaging and printing system,

[0048] The printing device includes a mother board, and a positioning mechanism matching the positioning hole is provided on the mother board; the printing device is configured to perform UV printing on a specified area of the paper to be printed when the paper to be printed is placed on the mother board at a position where the positioning hole is aligned with the positioning mechanism. The position of the positioning mechanism on the mother board cannot be changed and is used to cooperate with the positioning hole to place the paper in an accurate position, so as to perform printing accurately in the specified area. Therefore, the positioning mechanism needs to be convenient to cooperate with the positioning hole for alignment. In the present invention, the positioning mechanism is a bolt, and the bolt can be inserted into the positioning hole. When placing the paper to be printed, it only needs to be directly sleeved on the corresponding bolt through the positioning hole to achieve alignment.

[0049] In a technical solution of the above packaging and printing system,

[0050] The system further includes a workbench, and the workbench can adsorb or fix the paper to be printed for the vision system and / or the laser cutting system to operate. The workbench with the adsorption or fixing function can keep the paper to be printed flat and fixed for operation. Further, the workbench adopts a three-axis platform to capture markers or perform cutting operations in different areas.

[0051] One or more of the above technical solutions of the present invention have at least one or more of the following beneficial effects:

[0052] In implementing the technical solution of the present invention, the laser cutting technology is used to replace the paper cutter and the punching machine, making the cutting margins and positioning holes more accurate, so that the printed matter is easier to align, for precise printing in the designated area and improving the printing quality. By obtaining the cutting position data through marking and combining it with laser cutting, a large amount of time for aligning the paper can be saved, the process steps are simple, and the printing efficiency is effectively improved. At the same time, since manual alignment is not required, this printing method is easy to mass-produce and print, with high stability and quality consistency.

[0061] Some embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0062] As described in the background art, the existing packaging printing method has a too complex process. It requires a paper cutter to trim the edges and a punching machine to punch holes. It is very difficult and inaccurate to align the printing paper according to the registration marks and lines on the transparent plate of the punching machine. This mainly depends on the experience and eyesight of the operator. The alignment accuracy exceeds 0.2 mm, and the printing efficiency is low. It takes multiple repetitions to align the printed sheets, and it usually takes 5 - 10 minutes to complete the alignment of a single sheet. Once the alignment deviates or fails, the quality of the final overprint will decline, and the printed matter will become useless. At the same time, due to the different qualities of manual paper alignment, it is very difficult to promote the existing printing method on a large scale. Based on this, the present invention proposes a packaging printing method and system that can improve printing quality and efficiency.

[0063] Refer to the attached Figure 1 , Figure 1 is a schematic diagram of the main step process of a packaging printing method according to an embodiment of the present invention. As Figure 1 shown, a packaging printing method in an embodiment of the present invention is applied to a packaging printing system. The packaging printing system mainly includes a workbench, a vision detection system, and a laser cutting system. Based on the vision detection system and the laser cutting system, the paper to be printed on the workbench is positioned and cut to meet the requirements for printing within a specified area.

[0064] Specifically, the packaging printing method mainly includes the following steps S101 - step S104:

[0065] Step S101: Mark the paper to be printed, where the marked content includes cutting marks and registration marks;

[0066] In this embodiment, the method of marking the paper to be printed can be digital printing. The printed content includes the cutting marks of the edges and the registration marks for finding the positions of the positioning holes. Among them, digital printing can use a digital printer or other marking devices to make positioning marks on the paper that conform to the specified edge lines and hole positions.

[0067] Step S102: Obtain cutting position data according to the cutting marks and registration marks;

[0068] In one implementation, the vision detection system captures the cutting marks and registration marks and generates corresponding cutting position data in the vision detection system. Specifically, place the paper to be printed with marks on the workbench, capture the marks through the vision detection system, and generate corresponding cutting position data by simulating the contour in the vision detection system. Among them, the coordinate position of the cutting mark is the position of the cutting edge line, and the relative position between the coordinate position of the registration mark and the positioning hole is fixed. Therefore, the cutting position of the positioning hole can also be obtained through the coordinate of the registration mark. In this embodiment, the vision detection system uses a CCD vision system.

[0069] Step S103: Laser cut the edge lines and positioning holes of the paper to be printed according to the cutting position data.

[0070] In this embodiment, the edge lines are cut and holes are punched in the paper to be printed based on the laser cutting technology. The laser cutting technology can directly replace two devices, namely the paper cutter and the hole puncher, simplify the packaging and printing process, and has higher cutting accuracy, thus improving the packaging and printing quality.

[0071] In one embodiment, if the vision detection system is part of the laser cutting system, that is, the laser cutting system and the vision detection system use the same control computing system, it can be considered that they have the same coordinate system. Therefore, the cutting position obtained by the vision detection system is the actual cutting position, and the laser cutting system can directly perform corresponding cutting and punching according to the obtained cutting position.

[0072] In one embodiment, there is a certain deviation between the coordinate origins of the vision detection system and the laser cutting system. It is necessary to perform a certain compensation on the cutting position data obtained by the vision detection system to obtain the corresponding actual cutting position data in the laser cutting system. Set the laser cutting parameters according to the actual cutting position data, so as to laser cut the edge lines and positioning holes of the paper to be printed. Specifically, obtain the position deviation amount between the laser cutting system and the vision detection system, and compensate the cutting position data generated in the vision detection system according to the position deviation amount to obtain the corresponding actual cutting position data in the laser cutting system. The position deviation amount refers to the coordinate deviation amount of the same points in the coordinate system, and the deviation amounts of these same points are consistent. For the convenience of calculating the position deviation amount, the deviation amount is usually calculated through the origin coordinates of their respective systems.

[0073] For example, Figures 2 - 4 As shown in the figure, the coordinate transformation and compensation calculation process of the vision detection system and the laser cutting system Figure 2 is the paper to be printed with marks after digital printing, which can also be regarded as the original printing drawing in CAD. Its origin is the paper origin. The dotted lines at ① and ② are the cutting marks of the edge lines, ⑥ and ⑦ are the registration marks, and ③, ④, and ⑤ are all positioning holes. The relative distances between the registration marks and each positioning hole remain unchanged. Therefore, knowing the coordinates of the registration marks, the position coordinates of each positioning hole can be obtained. For example, when the coordinate of the registration mark ⑥ is (X, Y), the coordinates of the positioning holes ③, ④, and ⑤ are f1(X, Y), f2(X, Y), and f3(X, Y) respectively; Figure 3It is an image obtained by a vision detection system. In the coordinates of the vision detection system, the origin of the paper is still (0, 0). The captured registration mark ⑥ has corresponding position data (X, Y, θ), where θ represents the angle between the printed paper and the X-axis, that is, the vision detection system can obtain the deviation angle of the paper to be printed placed on the workbench. There is no alignment deviation, and there is no need to repeatedly place the paper for alignment. Figure 4 It is the drawing coordinates of a laser cutting system. When the origin of the vision detection system is (0, 0), the coordinate origin of the laser cutting system is (ΔX, ΔY). After the vision detection system sends the position data (X, Y, θ) of the registration mark ⑥ to the laser cutting system, the finally compensated coordinates of the registration mark ⑥ are (X + ΔX, Y + ΔY, θ). Correspondingly, the actual cutting position data of the positioning holes ③, ④, and ⑤ can be calculated according to the relative position relationship of the drawing, that is, f1(X + ΔX, Y + ΔY, θ), f2(X + ΔX, Y + ΔY, θ), and f3(X + ΔX, Y + ΔY, θ). Among them, since the paper to be printed is stationary on the workbench when the vision detection system performs detection and the laser cutting system performs cutting, θ remains unchanged.

[0074] Step S104: Place the paper to be printed on the corresponding preset printing position according to the position of the positioning hole, so as to perform printing in the specified area.

[0075] In one embodiment, the purpose of punching holes is to be able to place the paper to be printed on the corresponding preset printing position. There is a printing master plate on the printer, and there is a positioning mechanism on the master plate for cooperating with the positioning holes. Only when the positioning holes and the positioning mechanism are fully matched can the paper to be printed be accurately placed on the master plate, so as to accurately perform printing in the specified area. Usually, the positioning mechanism is fixed on the printing master plate and cannot be changed. Therefore, the accuracy of the positioning holes directly affects the printing quality. Based on the above steps S101 - S103, the vision detection system and the laser cutting system are used for positioning and cutting, which effectively improves the accuracy of the cutting edge line and punching holes, so that the printer can finally accurately print varnish in the specified area and improve the printing quality. In this embodiment, the positioning mechanism can adopt bolts, and the paper to be printed can be directly sleeved on the bolts through the positioning holes for final positioning.

[0076] Based on the above steps S101 - S104, in the embodiment of the present invention, by using the vision detection system to capture marks to obtain cutting position data in combination with the laser cutting page margin and positioning holes, a large amount of time for aligning the paper can be saved. The positioning and cutting of the positioning holes have higher accuracy, and the positioning accuracy can reach 0.03 mm. Based on the laser cutting technology to replace the paper cutter and punching machine, the process steps are simple, easy for large-scale production and printing, and have high stability and quality consistency.

[0077] It should be noted that although the above embodiments describe the various steps in a specific order, those skilled in the art can understand that in order to achieve the effects of the present invention, it is not necessary for different steps to be executed in such an order. They can be executed simultaneously (in parallel) or in other orders, and these variations are all within the protection scope of the present invention.

[0078] Furthermore, the present invention provides a packaging and printing system, including:

[0079] A marking device configured to mark the paper to be printed, wherein the marking content includes cutting marks and registration marks;

[0080] A vision detection system configured to obtain cutting position data according to the cutting marks and registration marks;

[0081] A laser cutting system configured to perform laser cutting of the edges and positioning holes on the paper to be printed according to the cutting position data;

[0082] A printing device having a preset printing position, and the paper to be printed is placed on the preset printing position according to the position of the positioning holes, so that the printing device performs printing in a specified area.

[0083] Refer to the attached Figure 5 , the paper 400 to be printed is placed on the workbench 100. The paper 400 to be printed has been digitally printed by a marking device such as a digital printer. The printed content includes cutting marks of ① and ② and registration marks of ⑥ and ⑦. The laser cutting system 300 needs to remove the margins along the cutting marks and punch holes; the positions of the positioning holes represented by ③, ④, and ⑤ need to be located and found through the registration marks of ⑥ or ⑦. The positioning holes are fixedly matched with the printing master plate of the printer, and their positions relative to the registration marks are fixed. The vision detection system 200 captures the registration marks and cutting marks, simulates the contour and sends the position data to the laser cutting system 300, so that the laser cutting system 300 performs cutting and punching according to the position data. Finally, the paper 400 with punched holes is placed in the printing device according to the position of the positioning holes and printed in the specified area. ⑧ is the printed pattern in the specified area.

[0084] In one embodiment, the vision detection system 200 adopts a CCD vision system. The CCD vision system includes an industrial camera 201, a reflector 202, a light source 203, and a light source controller. In actual use, appropriate equipment can be selected according to the image quality. In this embodiment, the light source controller performs the overall control of the entire system. The industrial camera 201 cooperates with the reflector 202 and the light source 203 to collect the image of the paper 400 to be printed. The light source controller captures the registration marks and cutting marks, simulates the contour calculation, and obtains the position data (including the coordinates of each point) of the cutting marks and registration marks and sends them to the laser cutting system 300.

[0085] In one embodiment, the laser cutting system 300 includes a laser 301 and a laser controller. The laser 301 is used to cut the paper to be printed 400. It can be an ultraviolet laser, a fiber laser, a CO2 laser, etc. The type of the appropriate laser cutting machine can be selected according to the performance and price ratio. The laser controller is used to receive the position data from the vision detection system 200 and calculate the actual cutting position data in the laser cutting system 300. For the calculation compensation process, refer to the calculation compensation method in the above packaging and printing method. The repeated parts will not be elaborated here. The laser 301 executes the corresponding cutting command according to the laser cutting parameters configured by the laser controller.

[0086] In one embodiment, the workbench 100 adopts a three-axis platform, which includes X, Y, and Z-axis movements. Since the printed matter usually has a large size (width range: 200 - 600 mm), while the working area of the laser 301 is small (width range: only 100 - 200 mm), the platform needs to move along the X and Y directions to cut in different areas. At the same time, the laser 301 also needs to move along the Z direction to adjust the laser focus point to obtain the minimum spot size. Further, the workbench 100 has an adsorption function, which can ensure the flat fixation of the paper to be printed 400 before laser cutting.

[0087] Based on the above embodiment, during the use of the packaging and printing system, first use a digital printer to complete the printing of the paper to be printed 400. The printed content of the paper to be printed 400 includes cutting marks and registration marks; place the printed paper to be printed 400 on the workbench 100. The workbench 100 is the laser cutting work platform. Capture the registration marks and cutting marks through the CCD vision system, generate the corresponding position data by simulating the contour, and send the position data to the laser controller of the laser cutting system. Then calculate the actual cutting position data according to the position data and the corresponding deviation; the laser controller sets the laser cutting parameters according to the actual cutting position data and controls the laser 301 to start cutting the side lines and positioning holes; place the paper to be printed 400 with holes on the mother board of the desktop flatbed UV printer, and insert the bolts fixed on the mother board into the drilled holes. For each printing device, the positions of the bolts are unchangeable. Therefore, the distances between the positioning holes remain the same; use the desktop flatbed UV printer to print UV varnish in the specified area to complete the printing. It should be noted that Figure 5 is a schematic diagram of some components in the packaging and printing system, and does not intend to convey the specific positions of various components.
