Description

Technical Field

[0001] This invention relates to the field of inkjet printing technology, and in particular to a smart positioning printing method, apparatus, and equipment that integrates etching. Background Technology

[0002] Inkjet printing is a technology that uses a printhead to spray ink onto paper or other printing materials to create patterns, text, or images. Inkjet printing is characterized by its high printing speed, low cost, and high print quality, and is widely used in various fields such as electronics, aerospace, and medical. However, due to factors such as the unevenness and smoothness of the material surface, inkjet printing often encounters problems such as print position misalignment and unstable ink flow, affecting printing accuracy and quality. To solve these problems, the industry has proposed laser etching before inkjet printing. This involves first etching an image using laser technology, creating a rough surface on the substrate to improve ink adhesion. Subsequent inkjet printing on this etched image results in a more durable print, improving print quality and stability. However, inaccuracies in the etched or inkjet printing areas during laser etching or inkjet printing can affect product quality, even leading to product scrap, impacting production efficiency, and causing waste.

[0061] Example 1

[0062] This invention provides a smart positioning printing method for fusion etching, which is applied to an inkjet printing system integrating a laser etching module, hereinafter referred to as a laser etching inkjet printing system, such as... Figure 1 As shown, the system includes a laser etching module 13, an inkjet printing module 11, and an image acquisition module 12, which can be a CCD / CMOS monocular camera, a 3D vision camera, or other similar devices. Figure 1As shown, the laser etching module 13 etches a pattern by sending a laser beam to the etching area 6 on the surface of the substrate 2; the image acquisition module 12 is used to acquire an image of the printing platform 3 or the substrate 2 on the printing platform 3; and the inkjet printing module 11 is used to inkjet print an image based on the etched pattern. Figure 1 As shown, in the above embodiment of the present invention, the laser etching module 13, the image acquisition module 12, and the inkjet printing module 11 are all mounted on the crossbeam 5. The laser etching module 13, the image acquisition module 12, and the inkjet printing module 13 can all reciprocate along the X direction on the crossbeam 5, and the crossbeam can reciprocate along the Y direction. The motion control module (not shown) of the laser etching inkjet printing system can drive the laser etching module 13, the image acquisition module 12, and the inkjet printing module 11 to move along the X and / or Y directions respectively, thereby irradiating the laser beam or spraying ink onto any position on the substrate 2 on the printing platform 3. The laser etching inkjet printing system obtains the positioning information of the laser etching module 13 or the inkjet printing module through a grating ruler (not shown). Furthermore, the distances between the laser etching module 13, the image acquisition module 12, and the inkjet printing module 11 and the printing platform 3 in the direction perpendicular to the plane of the printing platform (i.e., the XY plane) can be freely adjusted. The substrate 2 can be made of materials such as glass, crystal, metal, plastic (including PVC, ABS, acrylic, etc.), stone, etc. In this embodiment of the invention, the position information of the laser etching area obtained by the image acquisition module is matched with the current position information of the laser etching module obtained by the grating ruler on the printing platform, and the position information of the inkjet printing area obtained by the image acquisition module is matched with the current position information of the inkjet printing module obtained by the grating ruler on the printing platform, thereby further ensuring the accuracy of the laser etching area and the inkjet printing area.

[0063] Please see Figure 2 The intelligent positioning printing method of fusion etching includes:

[0064] S1: Control the image acquisition module to acquire the image of the substrate to obtain the first image;

[0065] S2: Determine the first position information of the etching area corresponding to the printing platform based on the first image;

[0066] S3: Control the laser etching module to move above the printing platform and obtain the second position information of the laser etching module according to the grating ruler on the printing platform;

[0067] S4: When the second position information matches the first position information, control the laser etching module to emit a laser beam to etch the substrate;

[0068] S5: Control the image acquisition module to acquire the image of the substrate that has been laser etched to obtain a second image;

[0069] S6: Determine the third position information of the printing area corresponding to the printing platform based on the second image;

[0070] S7: Control the inkjet printing module to move above the printing platform and obtain the fourth position information of the laser etching module according to the grating ruler on the printing platform;

[0071] S8: When the fourth position information matches the third position information, control the inkjet printing module to eject ink droplets to print on the substrate.

[0072] Specifically, to ensure the accuracy of the laser etching position and the inkjet printing position, in this embodiment of the invention, on the one hand, the image acquisition module is controlled to acquire an image of the substrate before laser etching, and the acquired electronic image is recorded as the first image. Then, image processing is performed on the first image to determine the etching area, and a rectangular coordinate system is established based on the point in the first image corresponding to the origin (zero point) of the grating ruler on the printing platform as the reference origin to obtain the first position information of the etching area relative to the printing platform. On the other hand, the image to be printed is rasterized to obtain a laser etching image that the laser etching module can recognize. During laser etching, the motion control of the laser etching inkjet printing system is... The module controls the laser etching module to move on the printing platform according to the etching parameters in the laser etching image. At this time, the laser etching module is positioned by the grating ruler on the printing platform. The laser etching module is equipped with a grating ruler reading module, which reads the encoder signal on the grating ruler and converts it into the position information of the laser etching module, which is recorded as the second position information. The second position information of the laser etching module is also based on the origin (zero point) of the grating ruler on the printing platform. When the second position information matches the first position information, it means that the current laser etching module is in the etching area. Therefore, the laser etching module is controlled to emit a laser beam onto the substrate to etch the substrate.

[0073] Similarly, to ensure the accuracy of inkjet printing position and the precise spraying of ink droplets onto the etched image on the substrate, on the one hand, the image acquisition module acquires an image of the laser-etched substrate, recording this acquired electronic image as the second image. Then, image processing is performed on the second image to determine the etched image on the substrate. Based on this etched image, the printing area is determined. Furthermore, a Cartesian coordinate system is established using the point in the second image corresponding to the origin (zero point) of the grating ruler on the printing platform as the reference origin, thereby obtaining the third position information of the printing area relative to the printing platform. On the other hand, the image to be printed is rasterized to obtain a dot matrix image (hereinafter referred to as the dot matrix image to be printed) that the inkjet printing module can recognize. During inkjet printing, the motion control module of the laser etching inkjet printing system controls the inkjet printing module to move on the printing platform according to the printing parameters in the dot matrix image to be printed. At this time, the grating ruler on the printing platform is used to position the inkjet printing module. The inkjet printing module is also equipped with a grating ruler reading module. The grating ruler reading module reads the encoder signal on the grating ruler and converts it into the position information of the inkjet printing module, which is recorded as the fourth position information. The fourth position information of the inkjet printing module is also based on the origin (zero point) of the grating ruler on the printing platform. When the fourth position information matches the third position information, it means that the inkjet printing module is currently in the printing area. Therefore, the inkjet module is controlled to spray ink droplets onto the substrate to print the substrate.

[0074] Preferably, the control image acquisition module acquires the image of the substrate to obtain the first image, including:

[0075] The height of the image acquisition module relative to the printing platform is adjusted so that the acquisition range of the image acquisition module can completely cover the printing platform, wherein a preset origin is marked on the printing platform, and the current position of the image acquisition device is recorded as the first acquisition position.

[0076] The image acquisition module is controlled to acquire images of the printing platform and the substrate placed thereon, thereby obtaining the first image.

[0077] Specifically, a preset origin (corresponding to the origin of the grating ruler) is marked on the printing platform. The height of the image acquisition module relative to the printing platform is adjusted so that the acquisition range of the image acquisition module can cover the entire printing platform, and the acquisition position is recorded so that the same acquisition position can be used to acquire a second image to determine the printing area. The acquired image is recorded as the first image, and the first image is processed and analyzed to obtain the etched area and its first position information relative to the printing platform.

[0078] Preferably, determining the first position information of the etched area corresponding to the printing platform based on the first image includes:

[0079] Extract the outline of the substrate from the first image;

[0080] A two-dimensional rectangular coordinate system is established with the point in the first image corresponding to the preset origin as the origin, and is denoted as the first coordinate system;

[0081] The etching area is determined based on the outline of the substrate;

[0082] The first position information is obtained by acquiring the coordinate information of the etched area in the first coordinate system.

[0083] Specifically, because the image acquisition module has a sufficiently large acquisition range to capture the entire printing plane, the image information of the first image includes the image information corresponding to the printing platform (denoted as the printing platform image) and the image information corresponding to the substrate image (denoted as the substrate image). Please refer to... Figure 3 Because a preset origin is marked on the printing platform, and point A (image) corresponding to this preset origin is on the first image, a rectangular coordinate system is established with point A as the origin, denoted as the first coordinate system. Image recognition processing technology is used to extract the printing platform image 30 and the substrate image 20 from the first image 10. In one embodiment, the system automatically determines the etching area based on the size of the etching pattern and the outline of the substrate image 20, as shown in the figure, etching area 60. In other embodiments, the user can manually identify the etching area in the first image through a graphical user interface, etc. After determining the etching area 60, the position information of the etching area 60 in the first coordinate system is obtained. For example, the etching area 60 is a rectangle, and the coordinates of its four vertices are (X10, Y10), (X20, Y10), (X10, Y20), and (X20, Y20), respectively. It can be seen that the first position information of the etching area in the substrate relative to the printing platform includes the information of all coordinate values ​​in the rectangular area composed of the four vertices.

[0084] Preferably, the step of controlling the laser etching module to emit a laser beam to etch the substrate when the second position information matches the first position information includes:

[0085] Determine whether the coordinate value corresponding to the second location information is in the first location information;

[0086] If so, the second position information is considered to match the first position information, and the laser etching module is controlled to emit a laser beam to etch the substrate.

[0087] Specifically, during laser etching, the motion control module of the laser etching inkjet printing system controls the movement of the laser etching module on the printing platform. The laser etching module is positioned using a grating ruler on the printing platform, and its position relative to the printing platform is acquired in real time. For example, such as... Figure 4 As shown, the current position of the laser etching module 13 is (X1, Y10), meaning the coordinates corresponding to the second position information are (X1, Y10). These coordinates are not within the rectangular area formed by the four vertex coordinates (X10, Y10), (X20, Y10), (X10, Y20), and (X20, Y20), i.e., not within the first position information. Therefore, the second position information does not match the first position information. For example... Figure 5 As shown, when the laser etching module 13 moves along the X direction to the coordinate (X10, Y10), the coordinate value corresponding to the second position information is (X10, Y10), which is included in the first position information. Therefore, the second position information is considered to match the first position information. At this time, the laser etching module 13 is controlled to emit a laser beam to etch the substrate.

[0088] As the laser etching module 13 continues to move along the X direction, as long as its horizontal coordinate is between X10 and X20 (the vertical coordinate Y10 remains unchanged), the coordinate values ​​corresponding to the second position information are all within the first position information. Therefore, the laser etching module 13 continues to emit laser beams to perform etching. The laser beam emission stops when the X coordinate value of the laser etching module 13 is greater than X20, at which point the coordinate values ​​corresponding to the second position information are no longer within the first position information. After the laser etching module 13 steps a certain distance along the Y direction, it enters the etching area from the X direction. Correspondingly, the second position information of the laser etching module 13 obtained from the grating ruler falls into the first position information, and the laser etching module 13 emits laser beams to perform etching… This continues until the entire etching area is completely etched.

[0089] After laser etching is completed, inkjet printing is then performed on the etched area. To ensure the accuracy of inkjet printing, in this embodiment of the invention, on the one hand, the image acquisition module is used again to acquire the image of the substrate to obtain a second image, and the position information corresponding to the printing area is obtained based on the second image. On the other hand, during inkjet printing, the position information of the inkjet printing module is obtained in real time using a grating ruler. Only when the two position information match is the inkjet printing module controlled to eject ink droplets to print the image.

[0090] Preferably, the control image acquisition module acquires the image of the substrate that has undergone laser etching to obtain the second image, including:

[0091] Adjust the position of the image acquisition device to the first acquisition position;

[0092] The image acquisition module is controlled to acquire images of the printing platform and the substrate placed thereon for laser etching, thereby obtaining the second image.

[0093] Specifically, in order to ensure that the second coordinate system established in the second image is the same as the first coordinate system, when acquiring the second image, the acquisition position of the image acquisition module is the same as the position when acquiring the first image, that is, at the position of the first acquisition image. The image acquisition module is controlled to acquire the image of the entire printing platform and the laser-etched substrate on it, thus obtaining the second image.

[0094] Preferably, determining the third position information of the printing area corresponding to the printing platform based on the second image includes:

[0095] Extract the etched image on the substrate from the second image;

[0096] The printing area is determined based on the region where the etched image is located;

[0097] A two-dimensional rectangular coordinate system is established with the point in the second image corresponding to the preset origin as the origin, and is denoted as the second coordinate system.

[0098] The third position information is obtained by acquiring the coordinate information of the printed area in the second coordinate system.

[0099] After obtaining the second image, the etched image on the substrate is extracted from it. The area corresponding to the etched image is the area to be inkjet printed, denoted as the printing area. Similarly, please refer to... Figure 6 ,and Figure 3 Similar to the previous example, because a preset origin is marked on the printing platform, and point B (image) corresponding to this preset origin is on the second image, a rectangular coordinate system is established with point B as the origin, denoted as the second coordinate system. In the second image, the printing platform image 300, the substrate image 200, and the etching image 600 are shown in the figure. Using image recognition processing technology, the etching image 600 is extracted from the second image 100, and the position information of the printing area corresponding to the etching image 600 in the second coordinate system is obtained. That is, the rectangular area corresponding to the coordinates of the four vertices (X100,Y100), (X200,Y100), (X100,Y200), and (X200,Y200) is obtained. It can be seen that the third position information of the printing area relative to the printing platform includes the information of all coordinate values ​​in the rectangular area composed of the above four vertices.

[0100] Preferably, controlling the inkjet printing module to eject ink droplets to print on the substrate when the fourth position information matches the third position information includes:

[0101] Determine whether the coordinate value corresponding to the fourth position information is in the third position information;

[0102] If so, the fourth position information is considered to match the third position information, and the inkjet printing module is controlled to eject ink droplets to print on the substrate.

[0103] Specifically, during inkjet printing, the motion control module of the laser etching inkjet printing system controls the movement of the inkjet printing module on the printing platform. The inkjet printing module is positioned using a grating ruler on the printing platform, and its position relative to the printing platform is acquired in real time. For example, such as... Figure 7 As shown, the current position of the inkjet printing module 13 is (X2, Y2), meaning the coordinates corresponding to the fourth position information are (X2, Y2). These coordinates are not within the rectangular area formed by the four vertex coordinates (X100, Y100), (X200, Y100), (X100, Y200), and (X200, Y200), i.e., not within the third position information. Therefore, the fourth position information does not match the third position information. For example... Figure 8 As shown, when the inkjet printing module 13 moves along the X direction to coordinates (X3, Y2), the fourth position information is considered to match the third position information in the third position information. At this time, the inkjet printing module 13 is controlled to eject ink droplets for image printing. During inkjet printing, the inkjet printing module is often controlled to reciprocate along the X direction and step along the Y direction to complete the printing of the entire printing area. When the fourth position information of the inkjet printing module 13 obtained according to the grating ruler falls into the third position information, the inkjet printing module 13 ejects ink droplets for image printing, and so on until the entire printing area is printed.

[0104] In summary, the intelligent positioning printing method with fusion etching provided by this invention acquires images of the substrate before and after laser etching using an image acquisition module to obtain a first image and a second image. Based on the first and second images, first and third position information of the etched area and the printing area relative to the printing platform are obtained, respectively. Second position information of the laser etching module and fourth position information of the inkjet printing module are obtained based on the grating ruler on the printing platform. When the second position information matches the first position information, the laser etching module is controlled to emit a laser beam to etch the substrate; when the fourth position information matches the second position information, the inkjet printing module is controlled to eject ink droplets to print on the substrate. This invention utilizes the combination of an image acquisition module and a grating ruler on the printing platform for automatic and precise positioning of the etched and printed areas in laser etching and inkjet printing, making the laser etching and inkjet printing images more accurate and efficient. This effectively avoids product quality problems caused by inaccurate laser etching or inkjet printing, thereby improving production efficiency.
