Description

Technical Field

[0001] The present application relates to the field of printing technology, and in particular to a registration device, system and method for a roll-to-roll printer. Background Art

[0002] In order to obtain high-quality printing results, when a printer is used to print multiple times on a printing medium, it is usually necessary to ensure that the graphic information printed each time can be accurately registered with each other. For example, in order to print a complex multi-color pattern on a printing medium, it is usually necessary to print the printing medium twice, three times, or even more times. In this case, in order to ensure the final printing effect, it is necessary to ensure that the graphic information printed each time can be accurately registered with each other.

[0003] However, for most roll-to-roll printers, due to their structural characteristics and their characteristics when running continuously and processing print media, these printing devices can only rely on operators to manually determine whether the graphic information printed each time can be aligned with each other. However, manual determination is not only time-consuming and laborious, but also easily limited by the operator's experience and skill level. Even for experienced operators, it is difficult to ensure that the graphic information printed each time can be accurately aligned with each other in most cases. Therefore, for most roll-to-roll printers, when the printer prints on the print media multiple times, it is often impossible to ensure that the graphic information printed each time can be accurately aligned with each other, and thus it is often impossible to obtain high-quality printing results.

[0004] Therefore, how to make the graphic information printed multiple times by the roll-to-roll printer on the printing medium more accurately register has become a technical problem that needs to be solved urgently. Summary of the invention

[0017] Alternatively, when it is determined that the image acquisition device cannot capture the registration mark on the pre-printed area, or cannot make the registration mark located at the predetermined position, a position adjustment prompt message is issued to prompt the adjustment of the position of the print medium at the paper feed port, and when the position is adjusted, it is re-determined whether the image acquisition device can capture the registration mark on the printed area and make the registration mark located at the predetermined position.

[0026] In a second aspect, an embodiment of the present application provides a registration system for a roll-to-roll printer, the registration system comprising: a registration device for a roll-to-roll printer provided in an embodiment of the present application and a roll-to-roll printer.

[0027] In a possible implementation, the roll-to-roll printer is configured to print a registration mark on at least one side edge of the print medium in the width direction during the first printing process.

[0028] In a third aspect, an embodiment of the present application provides a registration method for a roll-to-roll printer, which is used to register graphic information printed multiple times on a printing medium by the roll-to-roll printer, and the registration method includes:

[0029] Performing a first printing on a printing medium by means of a roll-to-roll printer, and controlling the roll-to-roll printer to print a registration mark on at least one side edge of the printing medium along a target direction during the first printing process; the target direction is a width direction of a paper inlet of the roll-to-roll printer;

[0030] After the first printing is completed, the image acquisition device in the registration device is controlled to move in the width direction to capture the registration mark, and when the registration mark is located at a predetermined position in the image of the printed medium, the position of the image acquisition device is fixed; wherein the registration device includes a support platform arranged facing the paper inlet, a bracket arranged on the support platform in the width direction, an image acquisition device arranged on the bracket, and a display screen coupled to the image acquisition device; the image acquisition device can move on the bracket in the width direction to acquire an image; the display screen is used to display the image;

[0031] Before each subsequent printing officially starts, the pre-printing area is pre-printed by a roll-to-roll printer; wherein the pre-printing area is arranged on at least one side edge of the printing medium along the paper feeding and discharging direction;

[0032] When pre-printing is completed, the position of the printing medium in the paper feed port is controlled so that the subsequently printed graphic information can be registered with the first printed graphic information; wherein, when it is determined that the image acquisition device can capture the registration mark on the pre-printed area and the registration mark is located at a predetermined position, it is determined that the subsequently printed graphic information can be registered with the first printed graphic information.

[0033] In a possible implementation, when pre-printing is completed, controlling the position of the printing medium at the paper inlet so that the subsequently printed graphic information can be registered with the first printed graphic information includes: performing the following steps at least once until it is determined that the subsequently printed graphic information can be registered with the first printed graphic information:

[0034] determining whether the image acquisition device can capture the registration mark on the pre-printed area of ​​the print medium and position the registration mark at a predetermined position;

[0035] When it is determined that the image acquisition device can capture the registration mark on the pre-printed area and the registration mark is located at a predetermined position, the position is maintained unchanged, and it is determined that the subsequently printed graphic information can be registered with the first printed graphic information;

[0036] Alternatively, when it is determined that the image acquisition device cannot capture the registration mark on the pre-printed area, or cannot locate the registration mark at the predetermined position, the current position is adjusted, and after adjusting the current position, it is re-determined whether the image acquisition device can capture the registration mark on the pre-printed area of ​​the print medium and locate the registration mark at the predetermined position.

[0037] Compared with the prior art, this application has the following advantages:

[0038] The registration device provided in the embodiment of the present application exists independently of the roll-to-roll printer, and can collect images of the printing medium through an image acquisition device arranged on a bracket, and use this to determine whether the graphic information printed each time can be registered. That is to say, the registration device provided in the embodiment of the present application can replace the operator's manual judgment method to determine whether the graphic information printed each time can be registered under the limitation of the structural characteristics of the roll-to-roll printer and its characteristics when it is continuously running and processing the printing medium, so as to ensure that the graphic information printed each time can be registered with each other, thereby providing a new registration judgment method for the roll-to-roll printer.

[0039] At the same time, by replacing the manual judgment method with a registration device, the influence of human factors in determining whether the graphic information printed each time can be registered can be significantly reduced, thereby ensuring more accurate confirmation of whether the graphic information printed each time can be registered, thereby ensuring that the graphic information printed each time can be more accurately registered with each other.

[0040] The registration system provided in the embodiment of the present application, because the registration device exists independently of the roll-to-roll printer, and can collect the image of the printing medium through the image acquisition device set on the bracket, and use this to determine whether the graphic information printed each time can be registered. That is to say, the registration system provided in the embodiment of the present application can replace the operator's manual judgment method to determine whether the graphic information printed each time can be registered under the limitation of the structural characteristics of the roll-to-roll printer and its characteristics when continuously running and processing the printing medium, so as to ensure that the graphic information printed each time can be registered with each other, thereby providing a new registration judgment method for the roll-to-roll printer.

[0041] At the same time, by replacing the manual judgment method with a registration device, the influence of human factors in determining whether the graphic information printed each time can be registered can be significantly reduced, thereby ensuring more accurate confirmation of whether the graphic information printed each time can be registered, thereby ensuring that the graphic information printed each time can be more accurately registered with each other.

[0042] The registration method provided in the embodiment of the present application can enable the image acquisition device to recapture the registration mark on the pre-printed area and reposition the registration mark to a predetermined position by accurately controlling the position of the print medium at the paper feed port when the image acquisition device stops moving. When the image acquisition device is able to recapture the registration mark on the pre-printed area and reposition the registration mark to a predetermined position, the registration mark on the pre-printed area will be in the same position as the registration mark on the print medium after the first printing is completed. In this way, the pre-printed area will be in the same position as the portion of the print medium after the first printing is completed.

[0043] In this case, if the subsequent printing of the printed medium is officially started, since the pre-printed area is in the same position as the part of the printed medium after the first printing is completed, then the printing path of the printed medium in the subsequent printing process will have a high probability of overlapping with the printing path in the first printing process. This printing path overlap will not only be reflected in the paper feeding and output directions, but also in the width direction of the paper feed. In the case that the printing path of the printed medium in the subsequent printing process has a high probability of overlapping with the printing path in the first printing process, the graphic information printed subsequently will have a high probability of being aligned with the graphic information printed for the first time. It can be seen from this that if the image acquisition device recaptures the registration mark on the pre-printed area and repositions the registration mark at the predetermined position, it is directly determined that the graphic information printed subsequently is aligned with the graphic information printed for the first time, and there is a high probability that the graphic information printed subsequently can be aligned with the graphic information printed for the first time.

[0044] Therefore, with the assistance of the registration device, the registration method can better ensure that the subsequently printed graphic information can be registered with the first printed graphic information by accurately controlling the position of the printing medium at the paper feed port, thereby better ensuring that the graphic information printed each time can be registered with each other.

[0060] The following describes the embodiments of the present application in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0061] Figure 1A and Figure 1B The specific structure of the registration device 100 for a roll-to-roll printer according to an embodiment of the present application is shown. Figure 2 The specific structure of the roll-to-roll printer 200 in the embodiment of the present application is shown. Figure 3 A schematic diagram of a portion of the printed medium after the first printing is completed is shown. Figure 1A , Figure 1B , Figure 2 as well as Figure 3 The registration device 100 in the embodiment of the present application is described.

[0062] The registration device 100 in the embodiment of the present application is used to register the graphic information printed multiple times by the roll-to-roll printer 200 on the printing medium 300. The registration device 100 includes: a support platform 110, a bracket 120, and an image acquisition device 130. Among them, the support platform 110 is arranged facing the paper inlet 210 of the roll-to-roll printer 200, the bracket 120 is arranged on the support platform 110 along the width direction of the paper inlet 210, and the image acquisition device 130 is arranged on the bracket 120. The image acquisition device 130 can move along the width direction on the bracket 120 to collect the image of the printing medium 300, so as to determine whether the graphic information printed each time can be registered.

[0063] It should be noted that the printing medium 300 refers to the material used to carry graphic information during the printing process, which can be in a roll or a flat plate. In other words, the roll-to-roll printer 200 can not only process roll materials, but also adapt to flat plate materials.

[0064] Specifically, Figure 1A As shown, in a possible implementation, the number of the image acquisition devices 130 is generally two. When the number of the image acquisition devices 130 is two, the two image acquisition devices 130 may be respectively referred to as a first image acquisition device 131 and a second image acquisition device 132. Meanwhile, when the number of the image acquisition devices 130 is two, the two image acquisition devices 130 may be respectively arranged on both sides of the bracket 120. In other words, the first image acquisition device 131 and the second image acquisition device 132 may be respectively arranged on both sides of the bracket 120.

[0065] In addition, if Figure 1B As shown, in a possible implementation, the number of the image acquisition device 130 may also be one, that is, only one image acquisition device 130 is disposed on the bracket 120 .

[0066] In the embodiment of the present application, the registration device 100 may further include a display screen 140. The display screen 140 is coupled to the image acquisition device 130 and is used to display images. Specifically, when the number of the image acquisition devices 130 is two, a display screen 140 may be configured for each of the first image acquisition device 131 and the second image acquisition device 132, or only one display may be configured for the first image acquisition device 131 and the second image acquisition device 132, that is, the first image acquisition device 131 and the second image acquisition device 132 share a display screen 140. When the first image acquisition device 131 and the second image acquisition device 132 share a display screen 140, the images captured by the two displays need to be displayed in different areas on the display, respectively.

[0067] The principle and process of the registration device 100 in the embodiment of the present application for determining whether the graphic information printed each time can be registered are as follows:

[0068] First, in the process of using the roll-to-roll printer 200 to print multiple times on the print medium 300, the roll-to-roll printer 200 performs the first printing on the print medium 300. At the same time, in the process of the first printing, the roll-to-roll printer 200 is controlled to print the registration mark 310 on at least one side edge of the print medium 300 along the width direction.

[0069] It should be noted that multiple printing includes: printing at least twice on the same printing surface of the printing medium 300, and printing on both sides of the printing medium 300. Graphic information generally refers to: printed content including text and / or images printed on the printing medium 300.

[0070] Secondly, after the first printing is completed, while fixing the position of the printing medium 300, the image acquisition device 130 in the registration device 100 is controlled to move in the width direction to capture the registration mark 310, and when the registration mark 310 is located at a predetermined position in the image of the printing medium 300, the position of the image acquisition device 130 is fixed.

[0071] In the embodiment of the present application, when the image acquisition device 130 includes the first image acquisition device 131 and the second image acquisition device 132, the roll-to-roll printer 200 can be controlled to print the registration marks 310 on both side edges of the printing medium 300 along the width direction during the first printing process. At this time, there is no specific requirement for the style of the registration mark 310, and the registration mark 310 can be personalized.

[0072] Meanwhile, when the image acquisition device 130 includes the first image acquisition device 131 and the second image acquisition device 132, in the process of controlling the image acquisition device 130 to move in the width direction to capture the registration mark 310 and place the registration mark 310 at the predetermined position, the first image acquisition device 131 needs to be moved in the width direction to capture the registration mark 310 on the same side as the first image acquisition device 131 in the width direction and place the registration mark 310 on the same side as the first image acquisition device 131 at the predetermined position. Correspondingly, the second image acquisition device 132 also needs to be moved in the width direction to capture the registration mark 310 on the same side as the second image acquisition device 132 in the width direction and place the registration mark 310 on the same side as the second image acquisition device 132 at the predetermined position.

[0073] It should be noted that since the display screen 140 is used to display the image captured by the image capture device 130, and the image is displayed in a specific area of ​​the display screen 140, so that the registration mark 310 is located at a predetermined position in the image can also be understood as the registration mark 310 is located at a specific position in the display screen 140.

[0074] When the image acquisition device 130 has only one data, the roll-to-roll printer 200 can be controlled to print a registration mark 310 on either side edge of the print medium 300 along the width direction during the first printing process. At this time, the registration mark 310 can be set as a vector symbol, for example Figure 2 The arrow “→” in the

[0075] Again, before each subsequent printing officially starts, the pre-printing area 320 is pre-printed by the roll-to-roll printer 200 .

[0076] Specifically, after the position of the image acquisition device 130 is fixed, it is necessary to ensure that the position of the image acquisition device 130 remains unchanged. In this case, subsequent printing can be started. However, before each subsequent printing officially starts, the print medium 300 that has been printed for the first time needs to be taken out from the paper outlet, and then the print medium 300 needs to be re-sent into the paper inlet 210. When the print medium 300 is re-sent into the paper inlet 210, the subsequent printing cannot be officially started, but the pre-printing area 320 needs to be pre-printed by the roll-to-roll printer 200.

[0077] In the embodiment of the present application, the pre-printing area 320 is disposed on at least one side edge of the printing medium 300 along the paper feeding and outputting direction. Figure 3 As shown, the pre-printing area 320 is arranged at both side edges of the printing medium 300 along the paper feeding and outputting direction.

[0078] Finally, when pre-printing is completed, by determining whether the image acquisition device 130 can capture the registration mark 310 on the pre-printing area 320 and locate the registration mark 310 at a predetermined position, it is determined whether the graphic information of each subsequent printing can be registered with the graphic information of the first printing.

[0079] Specifically, when it is determined that the image acquisition device 130 can capture the registration mark 310 on the pre-printed area 320 and locate the registration mark 310 at the predetermined position, it is determined that the subsequently printed graphic information can be registered with the first printed graphic information. When it is determined that the image acquisition device 130 cannot capture the registration mark 310 on the pre-printed area 320 or cannot locate the registration mark 310 at the predetermined position, it is determined that the subsequently printed graphic information cannot be registered with the first printed graphic information.

[0080] When it is determined that the image acquisition device 130 can capture the registration mark 310 on the pre-printed area 320 and locate the registration mark 310 at the predetermined position, the reasons why it can be determined that the subsequently printed graphic information can be registered with the first printed graphic information are as follows:

[0081] When the image acquisition device 130 is able to recapture the registration mark 310 on the pre-printed area 320 and reposition the registration mark 310 at the predetermined position, the registration mark 310 on the pre-printed area 320 will be at the same position as the registration mark 310 on the print medium 300 after the first printing is completed. In this way, the pre-printed area 320 will be at the same position as the portion of the print medium 300 after the first printing is completed. In this case, if the subsequent printing of the print medium 300 is officially started, since the pre-printed area 320 is in the same position as the portion of the print medium 300 after the first printing is completed, the print path of the print medium 300 in the subsequent printing process will have a high probability of overlapping with the print path in the first printing process, and this print path overlap will be reflected not only in the paper feeding and discharging direction, but also in the width direction of the paper feed port 210. In the case where the print path of the print medium 300 in the subsequent printing process has a high probability of overlapping with the print path in the first printing process, the image and text information of the subsequent printing will have a high probability of being registered with the image and text information of the first printing.

[0082] Therefore, when it is determined that the image acquisition device 130 can capture the registration mark 310 on the pre-printed area 320 and locate the registration mark 310 at a predetermined position, it can be determined that the subsequently printed graphic information can be registered with the first printed graphic information.

[0083] In addition, in order to better ensure that the subsequently printed graphic information can be aligned with the first printed graphic information, and further to better ensure that the graphic information printed each time can be aligned with each other, after the pre-printing is completed, the position of the printing medium 300 in the paper feed port 210 can be further controlled so that the subsequently printed graphic information can be aligned with the first printed graphic information.

[0084] Specifically, in the process of controlling the position of the printing medium 300 at the paper inlet 210 so that the subsequently printed graphic information can be registered with the first printed graphic information, the following steps may be performed at least once until it is determined that the subsequently printed graphic information can be registered with the first printed graphic information:

[0085] Step 1: Determine whether the image acquisition device 130 can capture the registration mark 310 on the pre-printed area 320 of the print medium 300 and locate the registration mark 310 at a predetermined position.

[0086] Step 2: When it is determined that the image acquisition device 130 can capture the registration mark 310 on the pre-printed area 320 and the registration mark 310 is located at a predetermined position, the position is maintained unchanged, and it is determined that the subsequently printed graphic information can be registered with the first printed graphic information;

[0087] Alternatively, when it is determined that the image acquisition device 130 cannot capture the registration mark 310 on the pre-printed area 320, or cannot locate the registration mark 310 at the predetermined position, the current position is adjusted, and after adjusting the current position, it is re-determined whether the image acquisition device 130 can capture the registration mark 310 on the pre-printed area 320 of the print medium 300, and locate the registration mark 310 at the predetermined position.

[0088] Since the image acquisition device 130 can recapture the registration mark 310 on the pre-printed area 320 and reposition the registration mark 310 at the predetermined position, the subsequent printing is started, and the image and text information printed subsequently will have a high probability of being registered with the image and text information printed for the first time. Therefore, if the image acquisition device 130 recaptures the registration mark 310 on the pre-printed area 320 and repositions the registration mark 310 at the predetermined position, it is directly determined that the image and text information printed subsequently is registered with the image and text information printed for the first time, and there is a high probability that the image and text information printed subsequently can be registered with the image and text information printed for the first time. In this way, with the assistance of the registration device 100, by accurately controlling the position of the printing medium 300 at the paper feed port 210, it can be better ensured that the image and text information printed subsequently can be registered with the image and text information printed for the first time, and then it can be better ensured that the image and text information printed each time can be registered with each other.

[0089] In the embodiment of the present application, when the image acquisition device 130 includes the first image acquisition device 131 and the second image acquisition device 132, the image acquisition device 130 can capture the registration mark 310 on the pre-printed area 320 and locate the registration mark 310 at the predetermined position, which specifically means that the first image acquisition device 131 can capture the registration mark 310 on the same side of the pre-printed area 320 and locate it at the predetermined position. At the same time, the second image acquisition device 132 can also capture the registration mark 310 on the same side of the pre-printed area 320 and locate it at the predetermined position.

[0090] When the first image acquisition device 131 is able to capture the registration mark 310 on the same side of the pre-printed area 320 and position it at a predetermined position, the registration mark 310 on the pre-printed area 320 on the same side of the first image acquisition device 131 will be at the same position as the registration mark 310 on the print medium 300 after the first printing is completed. Correspondingly, when the second image acquisition device 132 is able to capture the registration mark 310 on the same side of the pre-printed area 320 and position it at a predetermined position, the registration mark 310 on the pre-printed area 320 on the same side of the second image acquisition device 132 will be at the same position as the registration mark 310 on the print medium 300 after the first printing is completed. If the registration marks 310 on both sides of the pre-printed area 320 along the width direction of the print medium 300 are respectively at the same position as the registration marks 310 on both sides of the print medium 300 after the first printing is completed, then the pre-printed area 320 will be at the same position as the portion of the print medium 300 after the first printing is completed.

[0091] Therefore, when the image acquisition device 130 includes a first image acquisition device 131 and a second image acquisition device 132, it can be determined whether the image acquisition device 130 can capture the registration mark 310 on the pre-printed area 320 and make the registration mark 310 located at a predetermined position to determine whether the graphic information printed in each subsequent time can be registered with the graphic information printed for the first time.

[0092] In addition, when the number of image acquisition devices 130 is one, the registration mark 310 is a vector symbol, and its angle relative to a certain reference in the image can be used to represent the offset and angle of the pre-printed area 320 relative to the width direction. Therefore, when the image acquisition device 130 can recapture the registration mark 310 on the pre-printed area 320 and make the registration mark 310 located at a predetermined position, it indicates that the pre-printed area 320 will be at the same position as the portion of the printed medium 300 after the first printing is completed.

[0093] Therefore, when there is only one image acquisition device 130, it is also possible to determine whether the image acquisition device 130 can capture the registration mark 310 on the pre-printed area 320 and locate the registration mark 310 at a predetermined position to determine whether the graphic information printed in each subsequent time can be registered with the graphic information printed for the first time.

[0094] The registration device 100 provided in the embodiment of the present application can determine whether the graphic information printed each time can be registered with the graphic information printed for the first time through manual operation, and ensure that the graphic information printed subsequently can be registered with the graphic information printed for the first time.

[0095] In a possible implementation, in order to further improve the efficiency of determining whether the graphic information is registered, a processing device 150 may be installed for the registration device 100. The processing device 150 is connected to the image acquisition device 130 for communication, and is configured to determine whether the graphic information of each subsequent printing can be registered with the graphic information of the first printing according to the image.

[0096] Specifically, in order to enable the processing device 150 to determine whether the graphic information of each subsequent print can be registered with the graphic information of the first print, the processing device 150 can be specifically configured as follows: after the first print is completed, the image acquisition device 130 is controlled to move in the width direction to capture the registration mark 310, and the position of the image acquisition device 130 is fixed when the registration mark 310 is located at a predetermined position in the image; before each subsequent print is officially started, by determining whether the image acquisition device 130 can capture the registration mark 310 on the pre-printed area 320 and make the registration mark 310 located at a predetermined position, it is determined whether the graphic information of the subsequent print can be registered with the graphic information of the first print; and when it is determined that the image acquisition device 130 can capture the registration mark 310 on the pre-printed area 320 and make the registration mark 310 located at the predetermined position, it is determined that the graphic information of the subsequent print can be registered with the graphic information of the first print.

[0097] In addition, in order to further enable the subsequently printed graphic information to be more quickly registered with the first printed graphic information, in another possible implementation, the processing device 150 may be further configured to: before formally starting the subsequent printing, issue a pre-printing prompting message for prompting the roll-to-roll printer 200 to pre-print the pre-printing area 320; and when the pre-printing is completed, perform the following steps at least once until it is determined that the subsequently printed graphic information can be registered with the first printed graphic information:

[0098] Step 1: Determine whether the image acquisition device 130 can capture the registration mark 310 on the pre-printed area 320 and make the registration mark 310 located at a predetermined position;

[0099] Step 2: When it is determined that the image acquisition device 130 can capture the registration mark 310 on the pre-printed area 320 and the registration mark 310 is located at a predetermined position, it is determined that the subsequently printed graphic information can be registered with the first printed graphic information;

[0100] Alternatively, when it is determined that the image acquisition device 130 cannot capture the registration mark 310 on the pre-printed area 320, or cannot locate the registration mark 310 at the predetermined position, a position adjustment prompt message is issued to prompt adjustment of the position of the print medium 300 at the paper feed port 210, and when the position is adjusted, it is re-determined whether the image acquisition device 130 can capture the registration mark 310 on the printed area and locate the registration mark 310 at the predetermined position.

[0101] It should be noted that the processing device 150 may be communicatively connected to the roll-to-roll printer 200 . In this way, the processing device 150 may directly send pre-print prompt information to the roll-to-roll printer 200 to control the roll-to-roll printer 200 to pre-print the pre-print area 320 .

[0102] In a possible implementation, in order to make the registration device 100 adaptable to various roll-to-roll printers 200 and ensure that when the registration device 100 is used in conjunction with various roll-to-roll printers 200, its support platform 110 can carry the print medium 300 together with the paper inlet 210 to reduce the shaking or deviation of the print medium 300 during the printing process, the support platform 110 can also be used to carry the print medium 300. In this case, during the process of printing the print medium 300 using the roll-to-roll printer 200, the print medium 300 can be placed on the support platform 110 first, and then the print medium 300 can be controlled to slide from the support platform 110 into the paper inlet 210.

[0103] In order to ensure that the printing medium 300 slides smoothly from the support platform 110 into the paper inlet 210, it is usually necessary to set the height of the support platform 110 to be flush with the paper inlet 210. Specifically, a height adjustment mechanism 113 can be provided in the support component, so that the height of the support platform 110 is flush with the paper inlet 210 under the adjustment of the height adjustment mechanism 113. Providing the height adjustment mechanism 113 in the support component can also enable the registration device 100 to be adapted to a variety of roll-to-roll printers 200. Specifically, for roll-to-roll printers 200 of different heights, the height adjustment mechanism 113 can be adjusted according to the height of the paper inlet 210, so that the height of the support platform 110 can be flush with the paper inlet 210 of various roll-to-roll printers 200.

[0104] The support platform 110 is provided with at least one support structure 112, and the support structure 112 is arranged below the table 111 of the support platform 110, and is used to support the table 111. In the embodiment of the present application, the bracket 120 is arranged on the support platform 110 along the width direction of the paper inlet 210, specifically, the bracket 120 is arranged above the table 111 along the width direction of the paper inlet 210.

[0105] In one possible implementation, Figure 1A As shown in FIG. 1B , in order to ensure the stability of the table 111 , the support platform 110 is configured with four support structures 112 , and each support structure 112 is respectively disposed at a corner of the table 111 .

[0106] Meanwhile, the height adjustment mechanism 113 is disposed on the support structure 112. Specifically, the height adjustment mechanism 113 is a threaded adjustment mechanism disposed on the support structure 112, and can also be a telescopic adjustment mechanism disposed on the support structure 112.

[0107] It should be noted that in the embodiment of the present application, the specific form of the height adjustment mechanism 113 is not limited, that is, the height adjustment mechanism 113 can be a threaded adjustment mechanism, a telescopic adjustment mechanism, or other adjustment mechanisms with the same function.

[0108] In a possible implementation, the bracket 120 is disposed on the support platform 110 via the support component 190. Specifically, the bottom 192 of the support component 190 is disposed on one side edge of the support platform 110 along the width direction; the bracket 120 is disposed on the top 191 of the support component 190. Disposing the bottom 192 of the support component 190 on one side edge of the support platform 110 along the width direction can prevent the support component 190 from blocking the travel path of the printing medium 300.

[0109] like Figure 1A As shown, in order to improve the applicable scenarios of the registration device 100, the support component 190 can be movably arranged on the support platform 110. Specifically, the bottom 192 of the support component 190 is movably arranged on the support platform 110, and the bottom 192 of the support component 190 can move along the width direction on the support platform 110, so that the bottom 192 of the support component 190 can be arranged on a side edge of the support platform 110 along the width direction.

[0110] In one example, a pulley may be provided at the bottom 192 of the support component 190 , and a slide rail adapted to the pulley may be provided along the width direction of the table top 111 .

[0111] In one possible implementation, Figure 1A or Figure 1B As shown, a scale mark 160 is provided along the width direction on the support platform 110. The scale mark 160 is used to assist in confirming the position where the print medium 300 should be placed on the support platform 110 before each subsequent printing.

[0112] Specifically, during the first printing process, the scales corresponding to the two side edges of the printing medium 300 along the width direction, or the scales corresponding to the medium positioning mark 330, can be recorded first. In this way, before each subsequent printing, the position where the printing medium 300 should be placed on the support platform 110 can be determined based on the scales corresponding to the two side edges of the printing medium 300 during the first printing process, or the scales corresponding to the medium positioning mark 330, and the printing medium 300 can be placed on the support platform 110 accordingly. Before each subsequent printing, placing the printing medium 300 on the support platform 110 in this way can make the current placement position of the printing medium 300 roughly consistent with the placement position of the printing medium 300 on the support platform 110 during the first printing process. In this way, it can be ensured that the image acquisition device 130 can capture the registration mark 310 only by slightly moving the printing medium 300, or even without moving the printing medium 300.

[0113] It should be noted that when determining the position where the printing medium 300 should be placed on the support platform 110 based on the scale corresponding to the medium positioning mark 330, it is necessary to control the roll-to-roll printer 200 to print the medium positioning mark 330 on both side edges of the printing medium 300 along the width direction during the first printing process.

[0114] In one example, if Figure 3 As shown, the medium positioning mark 330 is closer to the two side edges of the printing medium 300 along the width direction than the registration mark 310 .

[0115] In a possible implementation, a laser emitter 170 may be further installed at the bottom of the image acquisition device 130. The laser emitter 170 emits a laser beam toward the support platform 110 to assist in confirming the position where the print medium 300 should be placed on the support platform 110 before each subsequent printing.

[0116] Specifically, during the first printing process, the approximate irradiation position of the laser beam on the print medium 300 can be recorded first, and this can be used to mark the approximate placement position of the print medium 300 on the support platform 110 during the first printing process. In this way, the position where the print medium 300 should be placed on the support platform 110 before each subsequent printing can be determined based on the approximate irradiation position. The position where the print medium 300 should be placed on the support platform 110 before each subsequent printing can be determined based on the approximate irradiation position, so that the current placement position of the print medium 300 can be roughly consistent with the placement position of the print medium 300 on the support platform 110 during the first printing process. In this way, it can be ensured that the image acquisition device 130 can capture the registration mark 310 by only slightly moving the print medium 300, or even without moving the print medium 300.

[0117] In one example, if Figure 1A As shown, when the image acquisition device 130 includes a first image acquisition device 131 and a second image acquisition device 132 , it is necessary to respectively set a first laser emitter 171 and a second laser emitter 172 in the first image acquisition device 131 and the second image acquisition device 132 .

[0118] like Figure 1A and 1B As shown, the registration device 100 provided in the embodiment of the present application can use the scale mark 160 in conjunction with the laser emitter 170 to jointly assist in confirming the position where the print medium 300 should be placed on the support platform 110. In addition, the scale mark 160 and the laser emitter 170 can also be used separately to assist in confirming the position where the print medium 300 should be placed on the support platform 110.

[0119] In addition, a scale mark 180 may be provided on the bracket 120, and the scale mark 180 is used to mark the distance between the image acquisition device 130 and the support member 190 in the width direction. Based on the distance between the image acquisition device 130 and the support member 190 in the width direction, it is also possible to assist in confirming the position where the printing medium 300 should be placed on the support platform 110.

[0120] It should be noted that in the embodiment of the present application, the bracket 120 is required to extend beyond the side of the paper feed port 210 in the width direction to ensure that when the image acquisition device 130 moves to the edge of the bracket 120 in the width direction, it can capture the registration mark 310 and the medium positioning mark 330 printed on the edge of the print medium 300 in the width direction.

[0121] In addition, when the multiple printing is front and back printing, it is necessary to ensure that the registration mark 310 can be displayed on the other side of the printing medium 300 through the printing medium 300 .

[0122] In the embodiment of the present application, the image acquisition device 130 can also move on the bracket 120 in the vertical direction and in the paper feeding direction and the opposite direction respectively; the image acquisition device 130 adjusts the shooting height by moving in the vertical direction, and adjusts the focal length by moving in the paper feeding direction and the opposite direction.

[0123] In addition, the image acquisition device 130 includes a camera or a digital magnifying glass.

[0124] The registration device provided in the embodiment of the present application exists independently of the roll-to-roll printer, and can collect images of the printing medium through an image acquisition device arranged on a bracket, and use this to determine whether the graphic information printed each time can be registered. That is to say, the registration device provided in the embodiment of the present application can replace the operator's manual judgment method to determine whether the graphic information printed each time can be registered under the limitation of the structural characteristics of the roll-to-roll printer and its characteristics when it is continuously running and processing the printing medium, so as to ensure that the graphic information printed each time can be registered with each other, thereby providing a new registration judgment method for the roll-to-roll printer.

[0125] At the same time, by replacing the manual judgment method with a registration device, the influence of human factors in determining whether the graphic information printed each time can be registered can be significantly reduced, thereby ensuring more accurate confirmation of whether the graphic information printed each time can be registered, thereby ensuring that the graphic information printed each time can be more accurately registered with each other.

[0126] Corresponding to the registration device provided in the embodiment of the present application, the embodiment of the present application also provides a registration system. Figure 4 As shown, it is a structural block diagram of a registration system 400 according to an embodiment of the present application. The registration system 400 may include: a registration device 100 and a roll-to-roll printer 200 provided in an embodiment of the present application.

[0127] In a possible implementation, the roll-to-roll printer 200 is configured to print a registration mark on at least one side edge of the print medium along the width direction during the first printing process.

[0128] The registration system provided in the embodiment of the present application, because the registration device exists independently of the roll-to-roll printer, and can collect the image of the printing medium through the image acquisition device set on the bracket, and use this to determine whether the graphic information printed each time can be registered. That is to say, the registration system provided in the embodiment of the present application can replace the operator's manual judgment method to determine whether the graphic information printed each time can be registered under the limitation of the structural characteristics of the roll-to-roll printer and its characteristics when continuously running and processing the printing medium, so as to ensure that the graphic information printed each time can be registered with each other, thereby providing a new registration judgment method for the roll-to-roll printer.

[0129] At the same time, by replacing the manual judgment method with a registration device, the influence of human factors in determining whether the graphic information printed each time can be registered can be significantly reduced, thereby ensuring more accurate confirmation of whether the graphic information printed each time can be registered, thereby ensuring that the graphic information printed each time can be more accurately registered with each other.

[0130] Corresponding to the registration device provided in the embodiment of the present application, the embodiment of the present application also provides a registration method for a roll-to-roll printer. The registration method is used to register the graphic information printed multiple times on the printing medium by the roll-to-roll printer, such as Figure 5 As shown, the registration method may include the following steps:

[0131] In step S501, a first print is performed on a print medium by means of a roll-to-roll printer, and the roll-to-roll printer is controlled to print a registration mark on at least one side edge of the print medium along a target direction during the first print; the target direction is the width direction of the paper feed port of the roll-to-roll printer.

[0132] In step S502, after the first printing is completed, the image acquisition device in the registration device is controlled to move in the width direction to capture the registration mark, and the position of the image acquisition device is fixed when the registration mark is located at a predetermined position in the image of the printed medium; wherein the registration device includes a support platform arranged facing the paper feed port, a bracket arranged on the support platform in the width direction, an image acquisition device arranged on the bracket, and a display screen coupled to the image acquisition device; the image acquisition device can move on the bracket in the width direction to acquire an image; and the display screen is used to display the image.

[0133] In step S503, before each subsequent printing officially starts, the pre-printing area is pre-printed by the roll-to-roll printer; wherein the pre-printing area is arranged at least on one side edge of the printing medium along the paper feeding and outputting direction.

[0134] In step S504, when pre-printing is completed, the position of the printing medium in the paper feed port is controlled so that the subsequently printed graphic information can be registered with the first printed graphic information; wherein, when it is determined that the image acquisition device can capture the registration mark on the pre-printed area and the registration mark is located at a predetermined position, it is determined that the subsequently printed graphic information can be registered with the first printed graphic information.

[0135] In the present application embodiment, Figure 6As shown, when pre-printing is completed, by controlling the position of the printing medium in the paper feed port so that the subsequently printed graphic information can be aligned with the first printed graphic information, steps S601-S603 can be executed at least once until it is determined that the subsequently printed graphic information can be aligned with the first printed graphic information.

[0136] In step S601, it is determined whether the image acquisition device can capture the registration mark on the pre-printed area of ​​the print medium and locate the registration mark at a predetermined position.

[0137] In step S602, when it is determined that the image acquisition device can capture the registration mark on the pre-printed area and locate the registration mark at the predetermined position, the position is maintained unchanged, and it is determined that the subsequently printed graphic information can be registered with the first printed graphic information.

[0138] In step S603, when it is determined that the image acquisition device cannot capture the registration mark on the pre-printed area, or cannot make the registration mark located at the predetermined position, the current position is adjusted, and after adjusting the current position, it is re-determined whether the image acquisition device can capture the registration mark on the pre-printed area of ​​the print medium and make the registration mark located at the predetermined position.

[0139] The registration method provided in the embodiment of the present application can enable the image acquisition device to recapture the registration mark on the pre-printed area and reposition the registration mark to a predetermined position by accurately controlling the position of the print medium at the paper feed port when the image acquisition device stops moving. When the image acquisition device is able to recapture the registration mark on the pre-printed area and reposition the registration mark to a predetermined position, the registration mark on the pre-printed area will be in the same position as the registration mark on the print medium after the first printing is completed. In this way, the pre-printed area will be in the same position as the portion of the print medium after the first printing is completed.

[0140] In this case, if the subsequent printing of the printed medium is officially started, since the pre-printed area is in the same position as the part of the printed medium after the first printing is completed, then the printing path of the printed medium in the subsequent printing process will have a high probability of overlapping with the printing path in the first printing process. This printing path overlap will not only be reflected in the paper feeding and output directions, but also in the width direction of the paper feed. In the case that the printing path of the printed medium in the subsequent printing process has a high probability of overlapping with the printing path in the first printing process, the graphic information printed subsequently will have a high probability of being aligned with the graphic information printed for the first time. It can be seen from this that if the image acquisition device recaptures the registration mark on the pre-printed area and repositions the registration mark at the predetermined position, it is directly determined that the graphic information printed subsequently is aligned with the graphic information printed for the first time, and there is a high probability that the graphic information printed subsequently can be aligned with the graphic information printed for the first time.

[0141] Therefore, with the assistance of the registration device, the registration method can better ensure that the subsequently printed graphic information can be registered with the first printed graphic information by accurately controlling the position of the printing medium at the paper feed port, thereby better ensuring that the graphic information printed each time can be registered with each other.
