[0002] Inkjet printing technology is a printing technology that uses a nozzle to spray ink onto paper or other printing materials to form patterns, texts or pictures. Inkjet printing technology has the characteristics of fast printing speed, low printing cost and good printing quality. Inkjet printing technology is widely used in various fields, such as electronics, aviation, medical, etc. However, due to factors such as the unevenness and smoothness of the material surface, problems such as printing position offset and unstable ink flow often occur during inkjet printing, which affects the printing accuracy and printing quality. In order to solve these problems, the industry has proposed a method of laser etching before inkjet printing, that is, first using laser etching technology to etch out the image, so that the surface of the substrate is uneven to form a certain degree of roughness, which helps the ink to form better adhesion with the surface of the substrate.

[0061] Embodiment 1

[0062] The embodiment of the present invention provides an intelligent positioning printing method for fusion etching, which is applied to an inkjet printing system integrated with a laser etching module, hereinafter referred to as a laser etching inkjet printing system. Figure 1 As shown, the system includes a laser etching module 13 and an inkjet printing module 11, and also includes an image acquisition module 12, which can be a CCD / CMOS monocular camera, a 3D vision camera, and the like. 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 the image of the printing platform 3 or the substrate 2 on the printing platform 3, and the inkjet printing module 11 is used to perform inkjet printing on the basis of the etching 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 arranged on the crossbeam 5, and the laser etching module 13, the image acquisition module 12 and the inkjet printing module 13 can 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 respectively along the X direction and / or the Y direction so that the laser beam can be irradiated or the ink can be sprayed to any position in 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). In addition, the distances between the laser etching module 13, the image acquisition module 12 and the inkjet printing module 11 relative to the printing platform 3 in the direction perpendicular to the plane where the printing platform is located (i.e., the XY plane) can be freely adjusted, and the substrate 2 can be glass, crystal, metal, plastic (including PVC, ABS, acrylic, etc.), stone, etc. In the embodiment of the present invention, the image acquisition module is used to obtain the position information of the etching area of ​​laser etching and the current position information of the laser etching module obtained by the grating ruler on the printing platform is matched, and the image acquisition module is used to obtain the position information of the printing area of ​​inkjet printing and the current position information of the inkjet printing module obtained by the grating ruler on the printing platform is matched, thereby further ensuring the accuracy of the laser etching area and the inkjet printing area.

[0063] See also Figure 2 , the intelligent positioning printing method of fusion etching includes:

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

[0065] S2: determining first position information of the etching area corresponding to the printing platform according to the first image;

[0066] S3: controlling the laser etching module to move above the printing platform and obtaining 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, controlling the laser etching module to emit a laser beam to etch the substrate;

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

[0069] S6: determining third position information of the printing area corresponding to the printing platform according to the second image;

[0070] S7: controlling the inkjet printing module to move above the printing platform and obtaining 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, the inkjet printing module is controlled to spray ink droplets to print on the substrate.

[0072] Specifically, in order to ensure the accuracy of the laser etching position and the inkjet printing position, in an embodiment of the present invention, on the one hand, the image acquisition module is controlled to acquire an image of the substrate before laser etching, and the electronic image acquired at this time is recorded as a first image, and then the first image is processed to determine the etching area, and a rectangular coordinate system is established based on the origin (zero point) of the grating scale on the printing platform corresponding to the point in the first image 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 can be recognized by the laser etching module. When laser etching is performed, the motion control of the laser etching inkjet printing system 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 using the grating ruler on the printing platform. The laser etching module is provided with a grating ruler reading module. The grating ruler reading module reads the encoder signal on the grating ruler and converts it into position information of the laser etching module, which is recorded as the second position information. The second position information of the laser etching module also uses the origin (zero point) of the grating ruler on the printing platform as a reference point. When the second position information matches the first position information, it indicates 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, in order to ensure the accuracy of the inkjet printing position and to ensure that the ink droplets can be accurately sprayed onto the etched image on the substrate during inkjet printing, on the one hand, the image of the substrate that has completed laser etching is collected by controlling the image acquisition module, and the electronic image collected at this time is recorded as the second image, and then the second image is processed to determine the etched image on the substrate, and the printing area is determined according to the etched image on the substrate, and a rectangular coordinate system is established according to the origin (zero point) of the grating scale on the printing platform corresponding to the point in the second image as the reference origin to obtain 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 that can be recognized by the inkjet printing module (hereinafter referred to as the dot matrix image to be printed). When performing 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. A grating ruler reading module is also provided on the inkjet printing module. The grating ruler reading module reads the encoder signal on the grating ruler and converts it into position information of the inkjet printing module, which is recorded as the fourth position information. The fourth position information of the inkjet printing module also uses the origin (zero point) of the grating ruler on the printing platform as a reference point. When the fourth position information matches the third position information, it indicates that the current inkjet printing module is in the printing area. Therefore, the inkjet printing module is controlled to spray ink droplets onto the substrate to print the substrate.

[0074] Preferably, controlling the image acquisition module to acquire the substrate image to obtain the first image comprises:

[0075] Adjusting the height of the image acquisition module relative to the printing platform 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 a first acquisition position;

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

[0077] Specifically, a preset origin (corresponding to the origin of the grating ruler) is marked on the printing platform, and 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 at the same time, so that the second image can be acquired at the same acquisition position 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 etching area and its first position information relative to the printing platform.

[0078] Preferably, determining the first position information of the etching area corresponding to the printing platform according to the first image comprises:

[0079] Extracting a printing substrate contour according to the first image;

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

[0081] Determining the etching area according to the outline of the substrate;

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

[0083] Specifically, since the acquisition range of the image acquisition module is large enough to complete the acquisition of the entire printing plane, the image information of the first image includes the image information corresponding to the printing platform (recorded as the printing platform image) and the image information corresponding to the substrate image (recorded as the substrate image). Figure 3 , because a preset origin is marked on the printing platform, and there is a point A (image) corresponding to the preset origin on the first image, a rectangular coordinate system is established with the point A as the origin, which is recorded as the first coordinate system. The printing platform image 30 and the substrate image 20 are extracted from the first image 10 using image recognition processing technology. In one embodiment, the system automatically determines the etching area according to the size of the etching pattern and the outline of the substrate image 20, as shown in the etching area 60. In other embodiments, the user can also manually identify the etching area in the first image through a graphic user interface. After the etching area 60 is determined, 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), (X20, Y20), respectively. It can be seen that the first position information of the etching area in the substrate relative to the printing platform is information including all coordinate values ​​in the rectangular area composed of four vertices.

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

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

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

[0087] Specifically, when performing laser etching, the motion control module of the laser etching inkjet printing system controls the laser etching module to move on the printing platform, positions the laser etching module through the grating ruler on the printing platform, and obtains the position information of the laser etching module relative to the printing platform in real time. For example, Figure 4 As shown, the current position of the laser etching module 13 is obtained as (X1, Y10), that is, the coordinates corresponding to the second position information are (X1, Y10). This coordinate is not within the rectangular area formed by the four vertex coordinates (X10, Y10), (X20, Y10), (X10, Y20), (X20, Y20), that is, it is not in the first position information. Therefore, the second position information does not match the first position information. 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. Then, it is considered that the second position information matches the first position information. At this time, the laser etching module 13 is controlled to emit a laser beam to etch the substrate.

[0088] When the laser etching module 13 continues to move in 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 in the first position information, so the laser etching module 13 is continuously controlled to emit a laser beam to perform etching. Until the X coordinate value of the laser etching module 13 is greater than X20, at which time the coordinate value corresponding to the second position information is not in the first position information, then stop emitting the laser beam. As the laser etching module 13 steps a distance in the Y direction and enters the etching area from the X direction, the corresponding second position information of the laser etching module 13 obtained according to the grating ruler falls into the first position information, and the laser etching module 13 emits a laser beam for etching... and so on until the entire etching area is etched.

[0089] After completing the laser etching, inkjet printing is then performed on the etched area. In order to ensure the accuracy of inkjet printing, in an embodiment of the present invention, on the one hand, the image acquisition module is used again to capture 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 grating ruler is used to obtain the position information of the inkjet printing module in real time. When the two position information match, the inkjet printing module is controlled to spray ink droplets to print the image.

[0090] Preferably, controlling the image acquisition module to acquire the image of the substrate that has been laser etched to obtain the second image comprises:

[0091] Adjusting 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 to complete laser etching, so as to obtain the second image.

[0093] Specifically, in order to make the second coordinate system established in the second image the same as the first coordinate system, when capturing the second image, the capturing position of the image capturing module is the same as that when capturing the first image, that is, both are at the first captured image position, and the image capturing module is controlled to capture the image of the entire printing platform and the image of the substrate that has been laser etched thereon, thereby obtaining the second image.

[0094] Preferably, determining the third position information of the printing area corresponding to the printing platform according to the second image comprises:

[0095] extracting an etching image on the substrate according to the second image;

[0096] Determine the printing area according to the area where the etching image is located;

[0097] A two-dimensional rectangular coordinate system is established with a point corresponding to the preset origin in the second image as a coordinate origin, which is recorded as a second coordinate system;

[0098] The coordinate information of the printing area in the second coordinate system is acquired to obtain the third position information.

[0099] After acquiring the second image, the etching image on the substrate is extracted from the second image. The area corresponding to the etching image is the area that needs to be inkjet printed, which is recorded as the printing area. Figure 6 ,and Figure 3 Because the preset origin is marked on the printing platform, there is a point B (image) corresponding to the preset origin on the second image, and a rectangular coordinate system is established with the point B as the origin, which is recorded 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. The etching image 600 is extracted from the second image 100 by using image recognition processing technology, 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 four vertex coordinates (X100, Y100), (X200, Y100), (X100, Y200), (X200, Y200) is obtained. It can be seen that the third position information of the printing area relative to the printing platform is the information including all coordinate values ​​in the rectangular area composed of the above four vertices.

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

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

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

[0103] Specifically, when performing inkjet printing, the motion control module of the laser etching inkjet printing system controls the inkjet printing module to move on the printing platform, positions the inkjet printing module through the grating ruler on the printing platform, and obtains the position information of the inkjet printing module relative to the printing platform in real time. For example, Figure 7 As shown, the current position of the inkjet printing module 13 is obtained as (X2, Y2), that is, the coordinates corresponding to the fourth position information are (X2, Y2). This coordinate is not within the rectangular area formed by the four vertex coordinates (X100, Y100), (X200, Y100), (X100, Y200), (X200, Y200), that is, it is not in the third position information. Therefore, the fourth position information does not match the third position information. Figure 8 As shown, when the inkjet printing module 13 moves to the coordinate (X3, Y2) along the X direction, in the third position information, it is considered that the fourth position information matches the third position information, and the inkjet printing module 13 is controlled to spray ink droplets to print the image. When performing 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.
