Description
Technical Field
The invention belongs to the technical field of laser die cutting design, and particularly relates to a method and a device for quickly adding a laser template.
Background
The laser template is a template scheme applied to mapping software in the field of laser die cutting and is used for matching a working area, an installation position and the like of a laser die cutting machine. The mapping software utilizes the position data of the laser to determine the cutting range, uses the position of a cross mark defined in the laser template to position the paper, and uses the range of the laser large plate area to position the initial cutting position. Laser die plates are particularly important in laser die cutting machines that have multiple lasers installed.
Currently, no special laser die cutting mapping software exists in the market, most of the software is self-developed graphic processing software, mainly processes the graphics cut by a single laser, and the software is in an unpublished state, only the section of PDF imposition expert (Guanhua edition) V3 which can perform the mapping operation of the graphics and generate the PLT file which can be identified by the laser is known at present, and the software also comprises a setting module of a laser template.
The laser template setting module of the PDF imposition expert defines a laser template by manually inputting the paper breadth, X, Y, width and height data of each laser area, laser large edition area and cross mark, and the cross mark is a printed cross symbol for positioning. If a laser die cutting machine is provided with a plurality of laser heads, data of a plurality of laser areas and corresponding laser large-plate areas need to be input into a laser template of the mapping software. Generally, at least one cross-mark data is input, and usually 2 cross-mark data are input to position the positioning camera on the laser die cutting machine. The amount of repetitive calculations is large and the number of values that need to be manually entered by the user is also very large. The user needs to calculate and input the data of the corresponding laser large plate area according to the X, Y, width and height of the laser area. Since the data for each region needs to be calculated manually, errors will also occur.
And because the error of each machine in the installation leads to the need to set up different laser templates in the mapping software, so even the machine of the same model can have different laser template data, thus lead to using the figure that the same template divides in the mapping software, can't be general on the machine of the same model, lead to the production flow can't standardize the operation, thus has additionally increased a lot of manual operations, for example need to set up different software templates because of the problem that the installation error leads to the machine of the same model.

Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
A method for rapidly adding a laser template, as shown in fig. 4, comprises the following steps:
step 1, creating a laser template and inputting a template name;
and 4, judging the legality of the input data, and if the input data is illegal, re-inputting the input data, and if the input data is legal, storing the template data.
The data input of the laser template is mainly divided into the following four parts:
1. the name of the laser template;
2. inputting a paper breadth (the length of the paper is in the horizontal direction, and the width of the paper is in the vertical direction, taking figure 1 as an example);
3. the cross mark position is input, the scheme only needs to input the X and Y positions of the cross mark in one paper feeding direction, and the positions of other cross marks are mutually symmetrical, so that the cross mark position can be automatically calculated by a program according to the breadth of paper and the input X and Y positions and drawn in a laser template preview window.
For example, 4 cross marks ("+") shown in fig. 1, the user only needs to input the X and Y positions of the cross mark at the upper left corner, and the Y position of the cross mark at the lower left corner can be obtained from the width of the paper-the Y position of the cross mark at the upper left corner, and the X position is the same as the X position of the cross mark at the upper left corner. The position of the cross mark at the upper right corner can be obtained from the paper length-the X position of the cross mark at the upper left corner, and Y is the same as the Y position of the cross mark at the upper left corner. The X position of the cross mark at the lower right corner is the same as the X position at the upper right corner, and the Y position is the same as the Y position of the cross mark at the lower left corner. Compared with the original method for adding the cross marks, the method for adding the cross marks greatly reduces manual input and input errors, thereby reducing production errors caused by input errors.
4. The data input of the laser area mainly comprises the following items:
(1) the center Y-coordinate of each laser,
(2) the width of the lasing area of each laser,
(3) the upper Y-coordinate position at which each laser operates,
(4) the Y-coordinate position of the lower limit of operation of each laser,
the position of the working lower limit Y of the laser area can be manually input at present, and is replaced by adding the width value of the laser to the upper limit Y, but the method is not very accurate, is not beneficial to the adjustment of the template under special conditions, and is more flexible and accurate due to manual input.
The X, Y and width and height data of the laser large plate area are calculated according to the input data of each laser, the cross mark and the paper breadth. The data of the corresponding laser area and the laser large-version area are generated at one time without manual input of a user. FIG. 2 shows a laser large plate area, and the related calculation method:
laser large plate area calculation, taking 760 (length of paper) 1060 (width of paper) as an example, and a laser working area of 380 as an example;
the width of the laser large plate area is X2-X1,
the height of the laser large plate area is Y2-Y1,
x2 is the width of the sheet + offset,
(X1+ X2)/2-cross-hatched X-coordinate,
x1 is 2X cross-labeled X coordinate-X2-offset,
y1-the center Y coordinate of the laser- (laser area width/2 of each laser) -offset,
y2 is the center Y coordinate of the laser + (width of laser area per laser/2) + offset,
the upper limit Y coordinate of the laser large plate area is Y1, the lower limit Y coordinate of the laser large plate area is Y2, the upper limit X coordinate of the laser large plate area is X1, and the lower limit X coordinate of the laser large plate area is X2; and the offset is an offset value and a numerical value is defined by user.
The laser working area 380 x 380 is just one example, and in practical application, the laser working area is input according to specific design data and is a variable value.
Similarly, compared with the original method, the method for generating the laser area and the laser large-version area greatly reduces manual input, and all data of the laser large-version area do not need to be calculated additionally and are calculated automatically by a program. The accuracy is higher, the error rate is reduced, and the data of each laser area is defined according to the design data of the machine, so that the production process is more standardized, the difficulty of machine calibration is reduced, a uniform standard can be referred to, and the calibration and setting of the machine are not required to be carried out according to the prior empirical value.
The design scheme of the laser template is shown in fig. 1, the laser area and the laser large plate area are shown in fig. 3, the small rectangular areas where the marks 1, 2 and 3 are located in fig. 3 are the areas needing to be cut by the 3 lasers respectively, and the large rectangular areas where the marks 1, 2 and 3 are located are the corresponding laser large plate areas (note: the laser large plate area is mainly used for aligning the cutting pattern with the laser center, namely, the pattern is aligned with the laser area center, so that the laser can cut the pattern correctly).
The template of fig. 1 is a 3-laser template, with overlapping regions due to the load balancing required to operate the machine. Load balancing is performed according to the number of bus bars to be cut in each zone, so that the difference of the total number of the lines cut by each laser is minimized, and the machine can reach the highest running speed.
The laser template is built up and will be used for the segmentation, the number of blocks into which the pattern is segmented depending on the number of lasers arranged in the template. For example, with 3 lasers in fig. 3, the pattern to be die cut would be divided into 3 large blocks, each assigned to a laser to cut. Generally, a machine with a plurality of lasers generates an overlapping area when each laser working area is set, and the overlapping area is mainly used for load balancing and graph integrity calculation.
For example, there is an overlapping area between the laser area 1 and the laser area 2 in fig. 3, if there are fewer lines to be cut in the laser area 1 and there are more lines to be cut in the laser area 2, the lines located in the overlapping area are preferentially allocated to the laser 1 for cutting, so as to reduce the waiting time of the lasers with less load, thereby achieving the purpose of synchronous operation of the lasers and improving the linear velocity of the pipeline. In another case, in order to ensure the integrity of the cut pattern, the lines located in the overlap region are preferentially allocated to the laser that cuts the complete pattern to which they belong, thereby reducing the defective rate. The setting of the laser template is crucial and directly corresponds to the physical position of the laser actually installed on the machine, the graph is directly placed on the machine after being divided, and the graph data is transmitted to the corresponding laser to work after being identified by the laser control software.
The laser on each machine is designed with corresponding mounting data such as work area, mounting location, etc. at the time of machine design. Our laser template addition scheme inputs template data according to the machine design data, and if the machine has running deviations according to the template, the machine needs to be adjusted according to our design data. This allows machines to be standardized, and the same laser template data can be used to segment patterns on the same model of machine. The production flow is unified and standardized while the manual repeated data input is reduced. Machine commissioning no longer relies on the experience of the operator, but rather calibrates the machine to design criteria.
The validity judgment of the input data in step 4 includes:
if the height is smaller than the height of the paper breadth, an error is reported, and the starting Y position and the ending Y position of each laser are wrong;
if the width and height value of the breadth of the paper is less than 0, reporting an error;
if the X and Y positions of the positioning coordinate (or the cross mark) are 0, or X is larger than the width of the paper breadth, or Y is larger than the height of the paper breadth, an error is reported;
if the central coordinate of the laser is 0, an error is reported;
and if the Y coordinate position of the lower limit of the laser operation-the upper limit Y coordinate position of the laser operation is larger than the working width of the laser, an error is reported.
Another embodiment of the present invention provides a device for rapidly adding a laser template, including:
the newly-built template module is used for establishing a laser template, inputting paper size data and inputting upper left cross-shaped data;
the laser area input module is used for inputting the laser area data of each laser to obtain the corresponding laser large-version area data;
and the data storage module is used for judging the legality of the input data, and storing the template data if the input data is illegal and input again.
