When the method is executed in an actual object processing process or device, it can be executed in the order of the method shown in the embodiments or drawings or in parallel (for example, in a parallel processor or multi-threaded processing environment).

[0040] Please refer to FIG. 2 to FIG. 4 . FIG. 2 is a flow chart of an embodiment of a laser scanning format calibration method provided in an embodiment of the present application. The laser scanning format calibration method includes:

[0041] 201. Obtain a currently selected target scanning format calibration type from among multiple preset scanning format calibration types of a laser processing device.

[0042] In the embodiments of this application, laser processing equipment utilizes laser beams for processes such as machining, cleaning, cutting, marking, welding, and engraving. It precisely processes materials by controlling parameters such as the laser beam's intensity, focus, and scanning path. Laser processing equipment primarily consists of a laser, an optical system, a control system, and a processing worktable. This application uses laser cleaning equipment as an example for illustration.

[0043] Laser cleaning equipment uses a laser beam to clean surfaces. The instantaneous high-energy laser beam vaporizes or removes dirt, paint, oxide layers, and other substances from the surface, achieving surface cleaning. Laser cleaning equipment primarily consists of a laser source, an optical system, a scanning control system, a cleaning nozzle, and a control system. The laser source generates a high-energy laser beam, which is focused and controlled by the optical system to create a high-density, high-energy beam. The scanning control system controls the laser beam's trajectory across the surface and the cleaning range.

[0044] Before using the laser cleaning equipment, it is usually tested. When errors are found in its scanning format, the laser cleaning equipment will be calibrated.

[0045] However, the related technology only calibrates a single fixed scanning format provided by the user. When there are multiple different cleaning orders or multiple different scanning format requirements in the same cleaning order, multiple calibrations are required. As a result, the calibration efficiency is low, affecting the normal use of the laser cleaning equipment.

[0046] To this end, the embodiment of the present application provides an operational interface for multiple preset scanning format calibration types on the operating system of the laser processing equipment, so that the staff can select the calibration type according to the current order requirements.

[0047] The plurality of preset scanning format calibration types include at least full format calibration. When the staff performs a selection operation, the system can obtain the currently selected target scanning format calibration type.

[0048] It should be noted that the multiple preset scanning format calibration types may also include ratio calibration, and details may be referred to the description of the following embodiment.

[0049] 202. If the target scanning format calibration type is full format calibration, obtain the lens type of the lens used by the laser processing equipment.

[0050] Due to the differences in parameters such as the size of the object to be cleaned and the cleaning intensity in the cleaning order, the types of lenses selected are different. Therefore, it is necessary to first configure the corresponding lens according to the cleaning order. After the configuration, the lens type used by the laser processing equipment can be obtained. Specifically, the lens type parameters can be entered by the staff in the system operation interface of the laser cleaning equipment.

[0051] 203. Based on the lens type, determine the maximum scanning format of the laser processing equipment.

[0052] In laser processing equipment, there's a close relationship between the lens and the scanning area. The lens primarily focuses the laser beam and controls the size and shape of the laser beam spot. The scanning area refers to the range of the laser beam's scanning on the work surface—the area covered by the laser beam during processing. The focal length of the lens determines the laser beam's ability to focus; the shorter the lens focal length, the greater the laser beam's ability to focus. There's a certain relationship between the lens focal length and the scanning area. By selecting the appropriate lens focal length, the size of the laser beam's focal point can be controlled, thereby achieving the desired processing effect across the scanning area.

[0053] In an embodiment of the present application, the step of determining the maximum scanning format of the laser processing equipment based on the lens type includes: obtaining a relationship mapping table between a preset lens type and the maximum scanning format; and determining the maximum scanning format of the laser processing equipment based on the relationship mapping table and the lens type.

[0054] The mapping table between the lens type and the maximum scanning format may be pre-set, and specifically includes a one-to-one correspondence between different lens types and the maximum scanning format.

[0055] Specifically, based on the relationship mapping table and the lens type, the maximum scanning format of the laser processing equipment is determined, which specifically includes: inputting the lens type into the relationship mapping table, and according to the one-to-one correspondence between the lens type and the maximum scanning format in the relationship mapping table, the maximum scanning format corresponding to the lens type can be obtained. For example, the maximum scanning format corresponding to the F160 lens is 100mm.

[0056] 204. Calibrate the maximum scanning width in sections to obtain a two-dimensional relationship array between a target ratio parameter and an actually set scanning width, wherein the target ratio parameter is represented by a first ratio of the target scanning width of all expected outputs of the laser processing equipment to the maximum scanning width.

[0057] In an embodiment of the present application, the maximum scanning format is segmented and calibrated to obtain a two-dimensional relationship array between the target proportion parameter and the actual set scanning format, including: segmenting the maximum scanning format to obtain multiple initial segmented scanning formats and a second ratio of each initial segmented scanning format to the maximum scanning format; based on the second ratio, determining a two-dimensional relationship array between the target proportion parameter and the actual set scanning format.

[0058] In an embodiment of the present application, segmenting the maximum scanning width may specifically include segmenting the maximum scanning width in equal proportion according to a preset target ratio. For example, if the target ratio is 10%, then segmenting in equal proportion according to 10% can obtain 10% of the maximum scanning width, 20% of the maximum scanning width, 30% of the maximum scanning width, 40% of the maximum scanning width, 50% of the maximum scanning width, 60% of the maximum scanning width, 70% of the maximum scanning width, 80% of the maximum scanning width, 90% of the maximum scanning width, and 100% of the maximum scanning width.

[0059] In a specific embodiment, the maximum scanning format is 130 mm, then 10% of the maximum scanning format is 13 mm, 20% of the maximum scanning format is 26 mm, 30% of the maximum scanning format is 39 mm, 40% of the maximum scanning format is 52 mm, 50% of the maximum scanning format is 65 mm, 60% of the maximum scanning format is 78 mm, 70% of the maximum scanning format is 91 mm, 80% of the maximum scanning format is 104 mm, 90% of the maximum scanning format is 117 mm, and 100% of the maximum scanning format is 130 mm.

[0060] In an embodiment of the present application, based on the second ratio, a two-dimensional relationship array between the target proportion parameter and the actual set scanning format is determined, including: determining the actual set scanning format corresponding to each second ratio; sorting all the second ratios according to a preset order to obtain a second ratio set; determining the linear relationship between any two adjacent second ratios in the second ratio set and their corresponding actual set scanning formats; based on the linear relationship, determining a two-dimensional relationship array between the target proportion parameter and the actual set scanning format.

[0061] The actual setting scanning width is characterized by that when the actual setting scanning width value is set on the laser processing equipment, the expected output scanning width corresponding to the actual output second ratio of the laser processing equipment can be obtained.

[0062] The distance is described with the second ratio of 10%. For example, the maximum scanning width is 130 mm, and the expected output scanning width is 10% of the maximum scanning width, that is, the expected output scanning width is 13 mm. At this time, the second ratio is 10%. However, due to errors in the laser processing equipment, if the actual scanning width is set to 13 mm, the actual output width cannot be 13 mm. Therefore, it is necessary to collect the actual setting scanning width of 15 mm corresponding to the actual output width of 13 mm.

[0063] In an embodiment of the present application, the preset order can be from small to large or from large to small. The present application is explained from small to large. All second ratios are sorted in order from small to large to obtain a second ratio set, which can obtain [10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%].

[0064] In the embodiment of the present application, a linear relationship between any two adjacent second ratios in the second ratio set and their corresponding actual set scanning widths is determined. For example, a linear relationship between 10% and 20% and their corresponding actual set scanning widths is determined:

[0065] For example: suppose the format is set to 10% (a 13mm format is required), but the actual cleaning format is only 13mm when the system needs to be set to 15mm. When the format is set to 20%, that is, the cleaning format needs to be 26mm, the actual system setting format is 28mm. For example, when the maximum scanning format is 10%, the actual setting scanning format is 15mm, and when it is 20%, it needs to be set to 28mm. The corresponding initial linear relationship is entered into y=kx+b, where x is the proportion parameter of the maximum scanning format, and y is the actual setting scanning format, that is, 15=0.1k+b; 28 = 0.2k+b, and the calculated k=130, b=2; therefore, the linear relationship within 10% to 20% is y = 130x+2.

[0066] It should be noted that the above only gives the linear relationship within 10% to 20%. In addition, there are linear relationships between 20% and 30%, 30% and 40%, 40% and 50%, 50% and 60%, 60% and 70%, 70% and 80%, 80% and 90%, and 90% and 100%. The calculation principles are the same and will not be repeated here.

[0067] In some embodiments of the present application, based on the linear relationship, determining the two-dimensional relationship array between the target proportion parameter and the actual setting scanning format includes: performing secondary segmentation on any two adjacent second ratios in the second ratio set to obtain multiple third ratios, and based on the linear relationship, respectively calculating the actual setting scanning format corresponding to each third ratio, and constructing a two-dimensional relationship array between the target proportion parameter and the actual setting scanning format based on the multiple third ratios and the corresponding actual setting scanning formats, and the multiple second ratios and the corresponding actual setting scanning formats.

[0068] The secondary segmentation may specifically include segmenting any two adjacent second ratios in the second ratio set in equal proportions according to a preset ratio, which may be 1%. Thus, multiple third ratios may be obtained. For example, segmenting 10% and its adjacent 20% by 1% may yield 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, and 20%.

[0069] Through the above embodiment, a two-dimensional relationship array of the actual set scanning width corresponding to all target proportion parameters with an interval of 1% from 10% to 100% can be obtained.

[0070] It should be noted that, if necessary, a two-dimensional relationship array of the actual set scanning width corresponding to all target proportion parameters with an interval of 1% from 0 to 100% can also be calculated.

[0071] 205. Based on the two-dimensional relational array, the scanning width of the laser processing equipment is calibrated.

[0072] In an embodiment of the present application, the scanning width of the laser processing equipment is calibrated based on the two-dimensional relationship array, including: obtaining the target scanning width expected to be output by the laser processing equipment; and calibrating the scanning width of the laser processing equipment based on the target scanning width and the two-dimensional relationship array.

[0073] In an embodiment of the present application, the scanning width of the laser processing equipment is calibrated based on the target scanning width and the two-dimensional relationship array, including: calculating the ratio parameter of the target scanning width and the maximum scanning width; inputting the ratio parameter into the two-dimensional relationship array to generate the actual setting scanning width corresponding to the ratio parameter; and calibrating the scanning width of the laser processing equipment through the actual setting scanning width.

[0074] For example, if the target scanning area is 20mm and the maximum scanning area is 130mm, then the ratio of the target scanning area to the maximum scanning area is 20 / 130 = 2 / 13 (approximately 0.154, or 15.4%). Since it is not an integer, it can be determined to be between 10% and 20%. According to the linear relationship calculated above, y = 130x + 2, y = 130*(20 / 130) + 2 = 22. Therefore, when the target scanning area is 20mm, the corresponding actual set scanning area should be 22mm. Then, 22mm is input into the laser processing equipment to calibrate the scanning area of ​​the laser processing equipment.

[0075] In an embodiment of the present application, a currently selected target scanning format calibration type is obtained from a plurality of preset scanning format calibration types of the laser processing equipment; if the target scanning format calibration type is full-format calibration, the lens type of the lens used by the laser processing equipment is obtained; based on the lens type, the maximum scanning format of the laser processing equipment is determined; the maximum scanning format is segmented and calibrated to obtain a two-dimensional relationship array of a target proportion parameter and an actually set scanning format, wherein the target proportion parameter is represented as a first ratio of the target scanning format of all expected outputs of the laser processing equipment to the maximum scanning format; based on the two-dimensional relationship array, the scanning format of the laser processing equipment is calibrated, and by adopting the full-format calibration method, it can calibrate the target scanning formats of multiple expected outputs, thereby improving the calibration accuracy and efficiency.
