[0002] In order to improve the efficiency of post-production of the inkjet printing industry, the industry now generally introduces professional engraving machines to directly engrave the pictures. The engraving machine can realize automatic feeding, automatic splitting of over-width pictures and continuous board engraving. In order to further improve the engraving efficiency, a QR code is generally added to the picture after adding the Mark point, so that the camera on the engraving machine head can scan the code to realize the engraving machine scanning point engraving.

[0003] However, in the case where the inkjet-printed images are not coated after output, the widths of several images are inconsistent. After scanning the first image, it is impossible to locate the QR code position of the second image and complete the scanning. Therefore, the purpose of automatic code scanning and automatic engraving of the entire roll of images cannot be achieved. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the existing technology of Shanshu. After the whole roll of picture is placed on the table of the engraving machine, the position of the picture aligned with the edge is far away from the origin of the engraving machine. A method for automatic engraving of the roll picture aligned far away from the engraving origin is provided, comprising the following steps: S1: Establish a coordinate system with the lower left corner of the engraving machine as the origin. The engraving machine automatically splits the super-frame image into several images of fixed lengths. Each image has different widths. A QR code is set at the lower left and upper right corners of each image. The QR code content includes the formatted file name and the location of the QR code. S2: putting the picture into a roll at the feeding place, taking out the picture and spreading it horizontally on the engraving machine platform, and the two sides with the marking points are parallel to the x-axis of the coordinate axis; S3: operating the camera of the engraving machine to scan the QR code on the left side of the first screen, and searching for an engraving target with a corresponding name from a set path according to the content of the QR code and opening the engraving target; S4: The engraving machine automatically scans points for engraving. After the engraving is completed, the engraving machine automatically feeds the material. The upper side edge of the new picture is aligned with the upper side edge of the picture one and the left side QR code coordinates of the new picture are calculated according to the left side QR code coordinates of the picture one. Repeat step S3 to complete the engraving.

[0005] Wherein, in step S1, setting a QR code at the lower left and upper right corners of each picture further includes: Setting a number of marking points on the left and right borders of each of the pictures; At the same time, the QR code content in the lower left corner is set to include the last eight characters of the engraving target file name plus the letter B, and the QR code content in the upper right corner is set to include the last eight characters of the engraving target file name plus the letter T.

[0006] Further, in step S2, the picture 1 is taken out and spread horizontally on the engraving machine platform, and the two side edges with the marked points are parallel to the x-axis of the coordinate axis, that is, on the engraving machine platform, the two QR codes on the picture 1 are respectively turned to the upper left and lower right positions.

[0007] Further, in step S3, operating the camera of the engraving machine to scan the QR code on the left side of the picture 1 specifically includes: First, manually operate the engraving machine camera to scan the QR code in the upper left position of the screen one, record the position coordinates of the QR code, obtain the first eight characters in the QR code content, that is, the last eight characters of the engraving target file name, and open the target whose corresponding name includes the eight characters from the set path.

[0008] In addition, operating the camera of the engraving machine to scan the two-dimensional code on the left side of the picture further includes: obtaining the last character in the content of the two-dimensional code, that is, the direction where the two-dimensional code is located, If the last character is B, then engraving starts directly according to the coordinate position of the QR code; If the last character is T, the opened engraving target file is rotated 180 degrees before engraving.

[0009] Further, in step S4, calculating the left side QR code coordinates of the new screen according to the left side QR code coordinates of the first screen specifically includes: The upper side of the new screen is aligned with the upper side of the first screen, so the vertical coordinate of the QR code in the upper left corner of the new screen is the same as the vertical coordinate of the QR code in the upper left corner of the first screen; The horizontal coordinate of the QR code at the upper left corner of the new screen is the horizontal coordinate of the QR code at the upper left corner of the first screen plus the distance between the two screens plus the length of the first screen.

[0010] In addition, calculating the left side QR code coordinates of the new screen according to the left side QR code coordinates of the first screen further includes: The engraving machine positions the camera to the position corresponding to the QR code according to the calculated position coordinates of the upper left corner of the new screen, obtains the content information of the current QR code after scanning, and opens the corresponding file name in the set path with reference to step S3 to complete the engraving.

[0011] Furthermore, step S3 and step S4 are repeated until the engraving of the entire frame is completed.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the case where the inkjet printed image is not coated after output, the width of the engraving machine screen in the Y direction is inconsistent. By aligning the screen to the edge at a position far away from the origin of the engraving machine, the position of the QR code on the second screen is calculated, thereby realizing automatic scanning and engraving of the entire roll of screen.

[0016] The position of the two-dimensional code on the screen is adjusted by the method of the present invention, and the head obtains the two-dimensional code when scanning the two-dimensional code of the first screen. Coordinates, after the first picture is engraved, the machine automatically feeds the material, the head The position remains unchanged, and then the interval value reserved for printing between two pictures set in the engraving software is added , you can get the second QR code value, so that the head can obtain the second QR code and coordinate( = ), so that you can scan the QR code of the second picture, identify the cutting path and automatically open the rotation direction to the same direction as the picture, and then scan the point to engrave. In this way, the automatic engraving of the entire roll of pictures is completed.

[0017] The specific implementation of the present invention is described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 As shown, the present embodiment provides a method for automatically engraving a web image by aligning the web image away from the engraving origin, as follows: S1: Establish a coordinate system with the lower left corner of the engraving machine as the origin. The engraving machine automatically splits the super-frame image into several images of fixed lengths. Each image has different widths. A QR code is set at the lower left and upper right corners of each image. The QR code content includes the formatted file name and the location of the QR code. S2: putting the picture into a roll at the feeding place, taking out the picture and spreading it horizontally on the engraving machine platform, and the two sides with the marking points are parallel to the x-axis of the coordinate axis; S3: operating the camera of the engraving machine to scan the QR code on the left side of the first screen, and searching for an engraving target with a corresponding name from a set path according to the content of the QR code and opening the engraving target; S4: The engraving machine automatically scans points for engraving. After the engraving is completed, the engraving machine automatically feeds the material. The upper side edge of the new picture is aligned with the upper side edge of the picture one and the left side QR code coordinates of the new picture are calculated according to the left side QR code coordinates of the picture one. Repeat step S3 to complete the engraving.

[0019] Wherein, step S1 further comprises: Set several marking points on the left and right borders of each picture, such as Figure 4 As shown, in this embodiment, four marking points are set on the left border of each picture, and three marking points are set on the right border of each picture; At the same time, the QR code content in the lower left corner is set to include the last eight characters of the engraving target file name plus the letter B, and the QR code content in the upper right corner is set to include the last eight characters of the engraving target file name plus the letter T.

[0020] Specifically, the engraving target file name of this embodiment is as follows: Figure 2As shown, the last eight characters are "22781308", so the QR code content in the lower left corner of this embodiment is "22781308B", and the QR code content in the upper right corner is "22781308T". Figure 3 shown.

[0021] In step S2, the picture 1 is taken out and spread horizontally on the engraving machine platform. The engraving machine platform is as follows: Figure 3 As shown. The two sides with the marking points are parallel to the x-axis of the coordinate axis, that is, on the engraving machine platform, the two QR codes on the screen 1 are respectively moved to the upper left and lower right positions. Figure 5 The arrangement is shown in Figure 1 above.

[0022] In step S3, operating the camera of the engraving machine to scan the QR code on the left side of the picture 1 specifically includes: First, manually operate the engraving machine camera to scan the QR code in the upper left position of the screen 1, record the position coordinates of the QR code, obtain the first eight characters in the QR code content, that is, the last eight characters of the engraving target file name, and open the target whose corresponding name includes the eight characters from the set path.

[0023] In addition, step S3 further includes: obtaining the last character in the content of the two-dimensional code, that is, the direction in which the two-dimensional code is located, If the last character is B, then engraving starts directly according to the coordinate position of the QR code; If the last character is T, the opened engraving target file is rotated 180 degrees before engraving.

[0024] This step avoids manual adjustment of the image orientation when feeding the image, thus improving work efficiency.

[0025] Further, in step S4, calculating the left side QR code coordinates of the new screen, screen 2, according to the left side QR code coordinates of screen 1 specifically includes: The upper side of the picture 2 is aligned with the upper side of the picture 1, so the vertical coordinate of the QR code in the upper left corner of the picture 2 is the same as the vertical coordinate of the QR code in the upper left corner of the picture 1; The horizontal coordinate of the QR code at the upper left corner of the picture 2 is the horizontal coordinate of the QR code at the upper left corner of the picture 1 plus the distance between the two pictures plus the length of the picture 1.

[0026] Step S4 further comprises: The engraving machine positions the camera to the position corresponding to the QR code according to the calculated position coordinates of the upper left corner of the picture 2, obtains the content information of the current QR code after scanning, and opens the corresponding file name in the set path with reference to step S3 to complete the engraving.

[0027] Repeat step S3 and step S4 until the engraving of the entire frame is completed.

[0028] The present invention provides a working principle or working process as follows: 1. When using a UV printer for output, lamination is generally not required. In this case, you need to add Mark points and QR codes when laying out the image. The QR codes should be placed at the lower left and upper right. Figure 4 The QR code content is the last 8 characters of the file name after typesetting (as shown in Figure 1), and the last letter is added according to the position. The QR code is T on the top of the screen and B on the bottom of the screen. Figure 4 The final screen is shown.

[0029] 2. When printing the picture, align it to the left, carry it to the feeding place of the engraving machine, unfold it and put it on the engraving machine platform (such as Figure 3 As shown in the figure), the side of the picture that is aligned is aligned away from the origin, such as Figure 5 shown.

[0030] 3. Such as Figure 5 As shown, the engraving machine camera is manually operated to scan the first QR code in screen 1, that is, the QR code in the lower left position of the screen. After obtaining the QR code information, remove the first 8 digits and search for the target containing this 8-digit string in the engraving path name from the set path to open, and then determine the direction of the path based on the last letter obtained. If it is B, open it directly, if it is T, rotate 180° and open it. In this way, the path position and the position of the screen on the engraving machine platform can be consistent. Record the QR code at the same time Axis position.

[0031] 4. The engraving machine automatically scans and engraves. After the engraving is completed, the machine automatically feeds the material so that the second version of the picture is close to the origin and the first version of the picture is Position plus the distance between the two pages (The distance between the two plates is controlled during printing) and the length of the picture 1 can be obtained Location( = + + ), then according to the obtained in step 3 Position, get the lower left QR code position of the second version of the screen ( , ), the engraving machine can find the corresponding QR code according to the location and scan the code to obtain the path information. Open the path to complete the engraving.

[0032] 5. Repeat steps 3-4 until the engraving of the scroll is completed.

[0033] In summary, the position of the two-dimensional code on the screen is adjusted by the method of the present invention (such as Figure 4 ), and the head obtains the QR code when scanning the QR code of the first picture. Coordinates, after the first picture is engraved, the machine automatically feeds the material, the head The position remains unchanged, and then the interval value reserved for printing between two pictures set in the engraving software is added , you can get the second QR code value, so that the head can obtain the second QR code and coordinate( = ), so that you can scan the QR code of the second picture, identify the cutting path and automatically open the rotation direction to the same direction as the picture, and then scan the point to engrave. In this way, the automatic engraving of the entire roll of pictures is completed.
