Description
Technical Field
The present invention relates to the field of data processing technologies, and in particular, to an exposure imaging control method, system, and related devices.
Background
Exposure imaging refers to exposing the exposed spots (mapped from the original image) on the photoresist-covered coating by a light source to produce the desired image on the photoresist coating after development. Common application scenarios include screen printing, PCB exposure imaging, and the like.
The applicant has found that the geometrical parameters of the image that can actually be imaged by exposure are limited due to limitations of the exposure process parameters employed by the exposure apparatus (e.g. mesh size, photoresist thickness, photoresist resolution, exposure power, etc.), the positioning accuracy of the apparatus itself. If the exposure process parameters adopted by the exposure equipment are not matched with the geometric parameters in the original dot matrix image to be imaged, the image precision of some specific areas (such as the areas with line width and minimum line distance and the intersection areas with too small acute angles) of the exposure imaging image generated on the photosensitive coating by the exposure equipment is not matched with the positioning precision of the light source, so that the exposed graph is different from the original graph. The method is characterized in that the problems of abnormal image, infirm edge solidification and the like occur in the intersection point area of the small sharp angle on the exposure imaging image due to the line width and the minimum line distance reduction loss of the exposure imaging image.

Detailed Description
In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
The terms first, second, third, fourth and the like in the description and in the claims and in the above drawings are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments described herein may be implemented in other sequences than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.
If the exposure process parameters adopted by the exposure device (comprising a laser array capable of moving horizontally and vertically, such as a laser direct exposure imaging device for plane screen printing in application number 201310084860.3) are not matched with the geometric parameters in the original dot matrix image to be imaged, some difficult areas (such as line width, area with too small minimum line distance and intersection area with too small acute angle) of the exposure imaging image generated by the exposure device on the photosensitive coating layer will be different from the original image. Each exposure imaging difference needs to be manually analyzed and adjusted, and the method is time-consuming, labor-consuming and low in efficiency. In order to improve exposure imaging efficiency, the applicant proposes pre-detection of an original image in advance and automatic modification of an incompatible partial image, so as to realize automatic adjustment of a difficult area.
For ease of understanding, a specific flow in the embodiment of the present invention is described below with reference to fig. 1, and an embodiment of an exposure imaging control method in the embodiment of the present invention may include:
s101: and judging whether a target image element of a preset type exists in the original dot matrix image.
In order to realize automatic adjustment of the difficult area, the system can firstly scan the original dot matrix image before exposure imaging and judge whether a target image element of a preset type exists in the original dot matrix image. If the target image element of the preset type is not available, adjustment is not needed, and the existing preset flow is executed.
Specific preset types of target image elements can be set according to requirements, for example, aiming at the problems of line width and minimum line distance reduction loss of an exposure imaging image, infirm solidification of an intersection point area of an excessively small acute angle on the exposure imaging image and the like, common target image elements can be parallel line segments and acute angles smaller than a threshold value (any angle value between 5 degrees and 15 degrees), and specific target image elements can be reasonably set according to different exposure process parameter limitations, and the method is not limited.
S102: and judging whether the geometric parameters of the target image element are in a compatible range or not.
If the target image element exists, the system needs to judge whether the geometric parameters of the target image element are in the compatible range. Alternatively, as a possible implementation, the system may pre-save the compatibility range of the geometric parameters of the target image element to which the exposure process parameter may be compatible, and then after acquiring the current value of the exposure process parameter, may query the compatibility range associated with the current value of the exposure process parameter.
Illustratively, determine if the spacing between parallel line segments is within compatibility? Or determining if an included angle of too small an acute angle is within a compatible range? Judging whether the line width of the line segment is within the compatible range? If the geometric parameters of the target image element are in the compatible range, no adjustment is needed, and the existing preset flow is executed.
S103: and adjusting the geometric parameters of the target image elements in the original dot matrix image to a compatible range, and performing exposure imaging according to the positions of the exposure points in the corrected dot matrix image generated after adjustment.
If the geometric parameters of the target image elements are not in the compatible range, the geometric parameters of the target image elements in the original dot matrix image are adjusted to the compatible range, and exposure imaging is performed according to the positions of the exposure points in the corrected dot matrix image generated after the adjustment, and a specific exposure imaging process can refer to the related technology and will not be described herein.
By way of example, in some possible embodiments, the spacing between parallel line segments may be adjusted to be within compatible ranges; in some possible embodiments, the inner region surrounded by the two edges of the acute angle can be subjected to pixel filling (the outer edge is unchanged), so that the local included angle is passivated to be within a compatible range; in some possible embodiments, the line width of the line segment may also be adjusted to be within a compatible range.
As can be seen from the disclosure, in the embodiment of the present application, a target image element of a preset type is identified by scanning an original dot matrix image before each exposure imaging, if the geometric parameter of the target image element is not within a compatible range, the geometric parameter of the target image element in the original dot matrix image is adjusted to the compatible range, and exposure imaging is performed according to the position of the exposure point in the corrected dot matrix image generated after the adjustment. Therefore, in the technical scheme, the original image is pre-detected, and the incompatible difficult area image is automatically modified, so that the automatic adjustment of the difficult area image is realized, the exposure process parameters are matched with the geometric parameters in the original dot matrix image required to be imaged, the manual participation in adjustment is not needed, and the quality of exposure imaging and the exposure imaging efficiency are improved.
The embodiment of the application also provides an exposure imaging control system, which can comprise:
the first processing unit is used for scanning the original dot matrix image and judging whether a target image element of a preset type exists in the original dot matrix image;
the identification unit is used for judging whether the geometric parameters of the target image element are in a compatible range or not if the target image element exists;
and the second processing unit is used for adjusting the geometric parameters of the target image elements in the original lattice image to the compatible range if the geometric parameters are not in the compatible range, and performing exposure imaging according to the positions of the exposure points in the corrected lattice image generated after the adjustment.
Optionally, as a possible implementation manner, the exposure imaging control system in the embodiment of the present application may further include:
the acquisition unit is used for acquiring the current value of the exposure process parameter and inquiring the compatibility range related to the current value of the exposure process parameter.
Optionally, as a possible implementation manner, in this embodiment of the present application, the second processing unit may include:

Optionally, as a possible implementation manner, in this embodiment of the present application, the second processing unit may include:
and the second adjusting module is used for filling pixels in an inner area of the included angle smaller than the threshold value in the original dot matrix image, so that the local included angle is passivated to a compatible range.
