Referring to fig. 2, in one embodiment, a method of controlling laser marking includes the steps of:
step S10, when the pattern to be marked is obtained, the pattern to be marked is segmented line by line to obtain a plurality of line segments;
in this embodiment, when the control device for laser marking obtains the input of the operator or the specified pattern to be marked, the pattern to be marked is segmented line by line to obtain a plurality of line segments. It can be understood that, during laser marking, the lines formed on the marked object have a certain width, so that after marking is performed according to the positions of the lines, a pattern to be marked can be formed on the marked object, for example, as shown in fig. 5 and 6, the pattern to be marked in fig. 5 and 6 is a ring pattern, and the lines in the ring pattern are simplified lines for embodying the marking path.
Optionally, the control device for laser marking may be an upper computer, and the upper computer is used for controlling the laser marking device to perform laser marking.
Step S20, acquiring a first line segment and a second line segment in the same line from the plurality of line segments;
in this embodiment, after dividing the pattern to be marked into a plurality of line segments, planning the marking path according to the plurality of line segments, specifically, a first line segment and a second line segment in the same row may be obtained in the plurality of line segments, and it can be understood that if a skip area exists in the row, the line segment in the row may be divided into at least two line segments by the skip area, that is, the row at least includes the first line segment and the second line segment, and if the skip area does not exist in the row, only one line segment exists in the row, so that the first line segment and the second line segment in the same row are obtained, that is, the line segment in the row in which the skip area exists is obtained.
Optionally, after the first line segment and the second line segment in the same row are obtained, the shortest distance between the first line segment and the second line segment may also be obtained, and when the shortest distance is less than or equal to the distance threshold, it is considered that the invalid marking path caused by the skip area is shorter, so that the step S30 and the step S40 may not be executed, but the second line segment is directly used as the next line segment to be marked of the first line segment, so that after the marking of the first line segment is finished, the marking is directly performed according to the path where the second line segment is located through the skip area; when the shortest distance is greater than the distance threshold, it is considered that the invalid marked path caused by the skip area is longer, and thus steps S30 and S40 may be performed to reduce the invalid marked path. For example, as shown in fig. 7, the black area in fig. 7 is a marking pattern, and the left upper portion of the black area has a skip area, but the length of the skip area in the same row is short, resulting in a short invalid marking path, and the left upper portion and the right upper portion of the black area also have a skip area, but the length of the skip area in the same row is long, resulting in a long invalid marking path.
Step S30, determining a third line segment closest to the first line segment in a next line of the first line segment;
and step S40, taking the third line segment as the next line segment to be marked of the first line segment, wherein marking is carried out according to the path of the third line segment after marking according to the path of the first line segment is finished.
In this embodiment, when a path is planned according to a plurality of line segments, the plurality of line segments need to be sequenced, and since the conventional way is marking line by line, for example, as shown in fig. 5, after marking a first line segment on the left side of a dotted line, the marking is performed on a second line segment on the right side of the dotted line, the marking is performed on the second line segment on the same line after passing through a skip area (i.e., a dotted line part) between the first line segment and the second line segment on the same line, and thus an invalid marking path (i.e., a skip area) exists, whereas in this embodiment, as shown in fig. 6, after the first line segment and the second line segment (i.e., line segment B and line segment H, or line segment C and line segment G) on the same line are obtained, a third line segment (i.e., line segment D or line segment B) closest to the first line segment in the next line of the first line segment is obtained, and the third line segment is used as a next line segment to be marked next to the first line segment, rather than the second line segment to be marked next to be marked as the first line segment, therefore, the marking path is prevented from passing through a skip region, the invalid marking path is reduced, and the whole marking path is shorter.
Optionally, if there are at least two segments (e.g., the segment B and the segment H in fig. 6) in the row where the third segment is located, that is, the fifth segment and the third segment belong to the same row, at this time, the third segment may also be used as the first segment in the present embodiment, and the fifth segment is used as the second segment in the present embodiment, and the path is continuously planned according to the manners of step S30 and step S40.
Optionally, the second line segment may be used as a next line segment to be marked of the third line segment, so that the marking is immediately performed according to the path where the second line segment is located after the marking is completed according to the path where the third line segment is located, or the second line segment may be used as a line segment to be marked in any order after the third line segment, so that the marking is performed according to the path where the second line segment is located after the marking is completed according to the path where the third line segment is located.
Optionally, when determining a third line segment closest to the first line segment in a next line of the first line segment, if only one line segment exists in the next line of the first line segment, the line segment may be used as the third line segment, and if multiple line segments exist simultaneously in the next line of the first line segment, the third line segment closest to the first line segment may be determined according to a shortest distance between each point of the multiple line segments and a marking end point of the first line segment, wherein when marking is performed according to a path where the single line segment exists, marking is performed usually from left to right or from right to left, and therefore, the marking end point of the first line segment is usually a left end point or a right end point of the first line segment.
In the technical scheme disclosed in the embodiment, the first line segment and the second line segment which are positioned on the same line in the pattern to be marked are determined, and after the marking of the first line segment is completed, the line segment on the next line is marked first, so that the marking of the second line segment through a skip area between the first line segment and the second line segment after the marking of the first line segment is completed is avoided, the invalid marking path is reduced, and the laser marking efficiency is improved.
In another embodiment, as shown in fig. 3, on the basis of the embodiment shown in fig. 2, after step S40, the method further includes:
a step S50 of detecting whether or not there is a fourth line segment belonging to a next line of the third line segment among the plurality of line segments;
in this embodiment, when the third line segment is used as the next line segment to be marked of the first line segment, it needs to be detected whether to immediately return to the previous line to mark according to the path where the second line segment is located after marking according to the path where the third line segment is located.
And step S60, if yes, taking the fourth line segment as a next line segment to be marked of the third line segment.
In this embodiment, if a fourth line segment that needs to be marked exists in the next line of the third line segment, after marking according to the path where the third line segment is located, marking needs to be performed according to the path where the fourth line segment is located, and the fourth line segment is used as the next line segment to be marked of the third line segment. After marking according to the path where the fourth line segment is located, whether the previous line needs to be immediately returned to mark according to the path where the unmarked line segment in the previous line is located is detected.
Optionally, if a fourth line segment which needs to be marked does not exist in the next line of the third line segment, it is indicated that the third line segment is the line segment in the last line, so that the previous line segment can be returned to mark according to the path where the second line segment is located, and the second line segment is used as the next line segment to be marked of the third line segment.
Optionally, if a fourth line segment needing to be marked does not exist in a next line of the third line segment, whether a fifth line segment which is in the same line as the third line segment exists in the line segments of the plurality of lines can be detected, if the fifth line segment does not exist, it is indicated that no skip area exists in the line where the third line segment exists, therefore, the previous line segment can be returned to mark according to a path where the second line segment exists, and the second line segment is used as a next line segment to be marked of the third line segment. If the fifth line segment in the same row as the third line segment exists, it indicates that the row in which the third line segment is located does not have a skip area, the third line segment is the line segment in the last row, and a wireless path caused by the skip area between the third line segment and the fifth line segment cannot be avoided, so that the fifth line segment can be used as the next line segment to be marked of the third line segment.
Optionally, after the fifth line segment is used as the next to-be-marked line segment of the third line segment, the second line segment may also be used as the next to-be-marked line segment of the fifth line segment, marking is performed on the unmarked line segments in a row from the last line segment step by step, that is, the line segments after the skip area are ignored first, marking is performed on the line segments from top to bottom line by line, and after marking is performed on the line segments from top to bottom line by line, marking is performed on the line segments after the skip area ignored previously, from bottom to top line by line, for example, as shown in fig. 6, after marking is performed according to the line segment a, the line segment on the right side of the skip area is ignored first, marking is performed from top to bottom line by line, for example, marking is performed on the line segments below the line segment B and the line segment B (including the line segments C, D, E and F) line by line, and then marking is performed on the line segments on the right side of the skip area ignored previously (including the line segments G and H) from bottom to top by line.
In the technical scheme disclosed in this embodiment, whether a fourth line segment which belongs to the next line of the third line segment exists or not is detected in the multiple line segments, if so, the fourth line segment is used as the next line segment to be marked of the third line segment, and the line segments behind the skip area are ignored, so that the line marking is performed line by line from top to bottom, the invalid marking path brought by the skip area is reduced as much as possible, and the laser marking efficiency is improved.
In yet another embodiment, as shown in fig. 4, on the basis of the embodiment shown in any one of fig. 2 to 3, the step S10 includes:
step S11, when the pattern to be marked is obtained, obtaining the number of edge points in the same line on the edge line of the pattern to be marked;
in this embodiment, when the pattern to be marked is obtained, it may be further detected whether a skip region exists in the pattern to be marked, specifically, points (i.e., edge points) on edge lines of the pattern to be marked may be obtained to determine the number of edge points in each row, and whether a skip region exists in the pattern to be marked is determined according to the number of edge points in the same row.
Optionally, since the human eye can easily distinguish whether the pattern to be marked has the skip region, it may also be determined whether the pattern to be marked has the skip region according to the control instruction input by the user, for example, if the control instruction input by the user is the first instruction, it is determined that the pattern to be marked has the skip region, and if the control instruction input by the user is the second instruction, it is determined that the pattern to be marked does not have the skip region.
And step S12, when the number is larger than the preset number, judging that the pattern to be marked has a skip area, and dividing the pattern to be marked line by line to obtain the multiple lines of line segments.
In this embodiment, when the number of the edge points in the same row is greater than the preset number, it is determined that the skip area exists in the pattern to be marked, and if the number of the edge points in the same row in each row is less than or equal to the preset number, it is determined that the skip area does not exist in the pattern to be marked.
Optionally, the preset number generally takes a value of 2. Alternatively, the number of edge points in the same row is typically 2 or a multiple of 2.
Optionally, if it is determined that the pattern to be marked does not have a skip region, marking is performed according to the pattern to be marked in a conventional manner, that is, marking is performed line by line, and if it is determined that the pattern to be marked has a skip region, the marking path is planned in a manner according to any one of embodiments of fig. 2 to 3 and marking is performed according to the planned marking path.
Optionally, when a plurality of lines of line segments are segmented line by line, and a first line segment and a second line segment in the same line are obtained in the plurality of lines of line segments, a start position and an end position of the line segment in each line may be determined according to a plurality of edge points in each line from left to right or from right to left, for example, a first line segment is located between a first edge point to a second edge point from left to right or from right to left, and a second line segment is located between a third edge point to a fourth edge point from left to right or from right to left.
In the technical scheme disclosed in this embodiment, the existence of the skip area in the pattern to be marked is determined according to the number of edge points in the same row on the edge line of the pattern to be marked, so that the detection of the skip area is realized.
