Embodiment 1
[0049] This embodiment describes in detail the method of inkjet printing a plurality of objects to be printed with exactly the same concave-convex features.
[0050] According to the laser sensor 11, the concave-convex feature 51 of the object to be printed 5 is obtained, and the software program judges the four extreme value position coordinate points A, B, C, D of the concave-convex feature 51 through the cross-sectional shape obtained on each YZ plane, and the software then converts the concave-convex feature 51 into the contour in the XY plane, such as image 3 As shown, C and D are the extreme position coordinate points of the X axis, and A and B are the extreme position coordinate points of the Y axis. The Y axis coordinates of point A are fed back by the laser sensor 11, and the Y axis coordinates are expressed as Y 1 Indicates that the Y-axis coordinate of point B is fed back by the laser sensor 11, expressed as Y 2 Indicates that the software calculates the Y axis co...
Embodiment 2
[0056] This embodiment describes in detail a method of inkjet printing a plurality of objects to be printed that have different concave-convex profiles but are completely consistent in depth.
[0057] The concave-convex feature profile of the object to be printed is the first concave-convex feature 501 and the second concave-convex feature 502 which are not the same, and the laser sensor 11 obtains the cross-sectional profile of the concave-convex feature on each YZ plane through one-pass scanning, such as Image 6 As shown, the laser sensor 11 scans the first concave-convex feature 501, and the software judges all feature points that form the contour edge of the first concave-convex feature 501 from the first contour feature point E until the last contour feature point F. The software program converts the concave-convex features into the contours in the XY plane. The grating ruler 21 marks the X-axis position coordinates. The laser sensor 11 calculates the Y-axis coordinates o...
Embodiment 3
[0063] This embodiment details a method for inkjet printing multiple objects to be printed that have multiple concave-convex features, one or two of which have regular shapes, and at least one of which has irregular shapes.
[0064] The object to be printed 55 has a plurality of concavo-convex features, to Figure 9For example, it includes the third concave-convex feature 503 , the fourth concave-convex feature 504 and the fifth concave-convex feature 505 , wherein the third concave-convex feature 503 and the fourth concave-convex feature 504 are of regular shape, and the fifth concave-convex feature 505 is of irregular shape. The coordinates of the center point M of the third concave-convex feature 503 and the center point N of the fourth concave-convex feature 504 can be obtained by using the laser sensor 11 and a software program, and the coordinates of the center point P of the fifth concave-convex feature 505 and the center point N of the third concave-convex feature 503 c...
