Detailed Description

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present invention, as the achievement, functional features, and advantages of the present invention are further described with reference to the embodiments, with reference to the accompanying drawings.

The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and 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 invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1, a processing method for adjusting focusing of a beam of a laser according to an embodiment of the present invention includes:

s1: constructing a simulated focusing track of a machined workpiece based on a preset focusing node, and performing simulated cutting machining on the machined workpiece according to the simulated focusing track;

s2: judging whether the cutting beam generates track deviation during the simulated cutting processing;

s3: if yes, adjusting the azimuth layout of the focusing node on the machined workpiece, and re-planning a cutting connecting line of the focusing node according to the azimuth layout, and generating to-be-cut content of the machined workpiece through the cutting connecting line, wherein the to-be-cut content is specifically focusing intensity, focusing depth and focusing cross section;

S4: judging whether the content to be cut has a fuzzy cutting point surface or not;

s5: if the fuzzy cutting point surface exists, at least one specific azimuth of each fuzzy cutting point surface is obtained, a cutting correction value of the fuzzy cutting point surface is captured based on a preset distance threshold value of the specific azimuth, a short-time focusing parameter of a laser machine is established according to the cutting correction value, the short-time focusing parameter is applied to repair the fuzzy cutting point surface, and the machined workpiece subjected to simulated cutting machining is obtained, wherein the short-time focusing parameter specifically comprises laser power, cutting speed and pulse frequency.

In this embodiment, the system constructs a simulated focus trajectory belonging to the machined workpiece based on a focus node preset on the machined workpiece, performs simulated cutting machining on the machined workpiece according to the simulated focus trajectories, and then the system determines whether a motion trajectory deviation is generated by the laser cutting beam during the simulated cutting machining process, so as to execute corresponding steps; for example, when the system determines that the laser cutting beam does not experience a trajectory deviation during the simulation process, the system will ensure that appropriate precautions and maintenance practices are taken with respect to the laser cutting machine to maintain operational performance, such as ensuring that the workpiece is properly secured to the work platform to prevent movement or vibration, while for the work material, a pre-treatment process such as cleaning, coating removal or edge preparation is required to ensure that the laser cutting is successful, and periodic maintenance of the laser cutting system, including cleaning of optical elements, replacement of lenses or lenses, maintenance of the laser; for example, when the system determines that the laser cutting beam generates a motion track deviation in the simulation process, the system re-plans the cutting connecting lines of all the focusing nodes according to the fixed positions to be processed on the processed workpiece by adjusting the position layout of the focusing nodes set on the processed workpiece in the simulation cutting process, generates different new cutting paths of the processed workpiece with the same content to be cut through the recombined cutting connecting lines, and inputs the new cutting paths into the five-axis laser machine for simulation cutting again; then the system judges whether a fuzzy cutting point surface exists in the content to be cut or not so as to execute corresponding steps; for example, when the system determines that there is no fuzzy cutting point surface in the content to be cut, the system considers that the laser cutting beam can accurately cut according to the designed path or pattern, no track deviation or inaccuracy occurs, the system needs to ensure that the optical path and the optical fiber of the laser system are not damaged, polluted or contaminated, the condition of the transmission path of the laser beam and the optical element is checked, an appropriate clamp and a fixing device are used in the cutting process, the workpiece is ensured not to move or deform in the cutting process, key parameters, workpiece specifications and cutting results in the cutting process are recorded, tracking and analyzing production data are facilitated, and the cutting process can be improved at any time in the later period; for example, when the system determines that a fuzzy cutting point surface exists in the content to be cut, the system acquires specific positions of the fuzzy cutting point surfaces on the machined workpiece, captures cutting correction values of the fuzzy cutting point surfaces based on preset distance thresholds among the specific positions, establishes short-time focusing parameters of the five-axis laser according to different cutting correction values, and repairs the fuzzy cutting point surfaces through the short-time focusing parameters, so that the machined workpiece subjected to simulated cutting machining can be obtained, namely, a simulated path representing simulated cutting machining can be used for cutting the machined workpiece in the five-axis laser.

It should be noted that, the specific procedure for establishing the short-time focusing parameters of the five-axis laser according to different cutting correction values is exemplified as follows:

assuming that a concave area is formed on the metal plate to be processed, laser cutting is required, the depth of the concave area is 2 mm, and the current standard focus position is 10 mm away from the surface of the workpiece;

calculating a focal position correction value: correction value = pit depth/2 = 2 mm/2 = 1 mm

New focal position=standard focal position-focal position correction value=10 mm-1 mm=9 mm

This means that in the recessed area the focal position is lowered from a standard 10 mm to 9 mm;

assume that the standard laser power of the five-axis laser is 100 watts

Calculating a laser power correction value: correction value = pit depth/2 = 2 mm/2 = 1 mm

New laser power = standard laser power (1-laser power correction value percent);

assuming that a 5% reduction in power in the recessed area is currently required

The new laser power is 100 watts (1-0.05) =95 watts

This means that in the recessed area we reduce the laser power from standard 100 watts to 95 watts;

and using the calculated focal position and laser power to establish short-time focusing parameters, wherein the focal position is 9 mm in a corresponding concave area, the laser power is 95W, the five-axis laser machine can repair the fuzzy cutting point surface through the short-time focusing parameters, if different distance thresholds do not exist in other fuzzy cutting point surfaces, the standard parameters are used, then the system inputs the standard parameters into the five-axis laser machine through a pre-written program to execute repair operation, the concave area is identified, and corresponding focal position and laser power correction values are automatically applied.

In this embodiment, the step S3 of adjusting the azimuth layout of the focusing node on the workpiece to be processed and re-planning the cutting connection line of the focusing node according to the azimuth layout includes:

s31: based on a preset fixed node on the machined workpiece, marking a key point position for carrying out azimuth replacement on the focusing node, carrying out layout adjustment on each focusing node according to preset simulation fixed point software, and resetting the connection relation among each focusing node;

s32: judging whether the connection relation changes the original cutting requirement of the processed workpiece or not;

s33: if not, drawing an arc curve path corresponding to the connection relation through the simulation fixed point software, and generating movement instruction contents of the laser cutting head in different paths according to the arc curve path to carry out self-adaptive correction, wherein the movement instruction contents specifically comprise a coordinate position instruction, a movement mode instruction and an auxiliary function instruction.

In this embodiment, the system identifies replaceable key focusing points based on fixed replaceable focusing nodes preset on the machined workpiece, applies preset simulation fixed point software to perform layout adjustment on each focusing node again, resets the connection relation of each focusing node, and then the system judges whether the connection relation changes the original cutting requirement of the machined workpiece so as to execute corresponding steps; for example, when the system judges that the connection relation can change the original cutting requirement of a processed workpiece, the system can continuously reset and adjust the connection relation on the basis of keeping the original cutting requirement of the processed workpiece, the system selects a proper focusing point position according to the geometric shape and the cutting requirement of the workpiece, the focusing point position directly influences the depth and the cutting effect of the cutting focus, the focusing point is included on the surface, the inside or the bottom of the workpiece and depends on the material and the shape to be cut, and meanwhile, if a plurality of focusing point positions are needed on the workpiece, the relative positions among all focusing nodes are considered, so that the focusing points can not interfere with each other or generate conflict, the focusing points are accurately distributed through a control system of the five-axis laser machine, and the laser parameters including laser power, speed and pulse frequency are adjusted according to the new focusing point position; for example, when the system judges that the connection relation does not change the original cutting requirement of the machined workpiece, the system draws an arc curve path corresponding to the connection relation through simulation fixed point software, and generates the machined workpiece according to the arc curve path.

It should be noted that, a specific example of drawing the arc curve path according to the connection relationship of the focus node is as follows:

assuming that a workpiece is to be machined, cutting is performed at four corners of the workpiece, it is desirable that the cutting path connects the corners in the form of circular arcs, the workpiece is a square, the cutting radius of each corner is 10 mm, the connection relationship has been determined as four focus nodes, which are respectively located at the four corners of the workpiece, the cutting requirement is to cut a circular arc with a radius of 10 mm at each focus node, and the connection path is drawn:

a. drawing starting point (Angle A)

b. Drawing a first arc: the specified radius is 10 mm, the starting point is angle A, and the end point is angle B

c. Drawing end point connected to angle B

d. Drawing a second arc: the specified radius is 10 mm, the starting point is angle B, and the end point is angle C

e. Drawing end point connected to angle C

f. Drawing a third arc: the specified radius is 10 mm, the starting point is angle C, and the end point is angle D

g. Rendering end points connected to angle D

h. Drawing a fourth arc: the specified radius is 10 mm, the starting point is an angle D, and the end point is an angle A;

after the radius and the position of the arc meet the requirements, using simulation fixed point software to verify the accuracy and the suitability of the path, ensuring that the arc path meets the cutting requirements, converting the drawn path into a machine language G-code, inputting the G-code into a five-axis laser machine for execution, loading the generated G-code program onto the five-axis laser machine, and performing actual cutting operation, wherein the arc path is smooth and has no sharp turning or corner, so that the acceleration and the deceleration of the cutting head can be reduced, the mechanical vibration on the cutting track can be reduced, the cutting quality is improved, meanwhile, the arc path allows the cutting head to keep a more consistent speed in the cutting process without frequent acceleration and deceleration, the production efficiency can be improved, the cutting time is shortened, and the arc path allows the motion of the cutting head to be controlled more accurately, thereby realizing more accurate cutting.

In this embodiment, the step S5 of repairing the blurred cut point surface by applying the short-time focusing parameter to obtain the machined workpiece after the simulated cutting machining includes:

s51: adjusting a focus parameter of the laser cutting head based on a preset ranging value of the laser cutting head and the fuzzy cutting point surface, wherein the focus parameter specifically comprises a Z-axis position and a focus diameter;

s52: judging whether the focus parameter is suitable for the fuzzy cutting point surface or not;

s53: if yes, capturing a repairing path in real time through a scanning head preset on the laser cutting head, and adjusting the laser beam position transformation of the laser cutting head according to the repairing path.

In this embodiment, the system adjusts the focal parameters of the laser cutting head based on the preset distance measurement values of the laser cutting head and the fuzzy cutting point surface, and then the system judges whether the focal parameters are suitable for the fuzzy cutting point surface or not to execute the corresponding steps; for example, when the system determines that the focal parameters cannot be adapted to the fuzzy cutting point surface, the system can monitor the height change of the workpiece surface during processing in real time by using preset automatic focusing and adjust the focal position in real time to maintain the optimal cutting quality, meanwhile, through preset dynamic focal technology, the focal position is automatically adjusted to adapt to the change of the workpiece surface during cutting, and a plurality of focuses are used for simultaneously cutting areas with different depths, the multi-focus cutting allows a plurality of areas with different depths to be processed simultaneously, so that the processing time is shortened, the energy can be dispersed in multi-focus cutting, and therefore, the thermal influence on any one focus is relatively small, the thermal deformation and color change of materials can be reduced, and the cutting quality is improved; for example, when the system determines that the alternating current parameter can be adapted to the fuzzy cutting point surface, the system captures a repairing path of repairing the fuzzy cutting point surface in real time through a scanning camera preset on the laser cutting head, and adjusts the laser beam position transformation of the laser cutting head according to the repairing path.

The specific examples of the laser beam position change for adjusting the laser cutting head according to the repair path are as follows:

the method is characterized in that a laser cutting machine is used for repairing a welding line on a metal workpiece, the position and the shape of the welding line change due to the manufacturing process, at the moment, the system captures data of a real-time repairing path, the position and the shape of a welding line are expected to be changed according to the data, the captured data are captured in real time through a laser sensor or a vision system, specific requirements of the welding line repairing path, including coordinates, shape and length of the path, the position and the focal position of a laser beam are adapted to the position and the shape of the welding line through controlling a moving system of the laser cutting head according to the analyzed data, if the welding line deviates, the welding line is aligned through adjusting the coordinates of the laser cutting head, and meanwhile, laser parameters, including power and focal length, are required to be adjusted according to the material and shape characteristics of the welding line, so that the quality of the welding line repairing is ensured.

In this embodiment, after step S3 of generating the content to be cut of the machined workpiece through the cutting connection line, the method further includes:

s301: identifying a machining position of the machined workpiece on a laser cutting machine;

s302: judging whether the processing position is matched with the preset position of the laser cutting machine or not;

s303: if not, clamping the machined workpiece by using a preset clamping tool, and after correcting the machining position to the preset position, cutting the machined workpiece, wherein the cutting pretreatment specifically comprises cutting equipment maintenance, temperature control and cutting mode selection.

In the embodiment, the system identifies the processing position of the processing workpiece on the five-axis laser machine, and then judges whether the processing position matches the preset processing positioning of the five-axis laser machine or not so as to execute the corresponding steps; for example, when the system determines that the machining position can be matched with the machining position originally set by the laser cutting machine, the system considers that the machining position of the workpiece is accurately set to be the position where the laser cutting machine is fixedly arranged, so that the system is good in equipment arrangement and workpiece clamping, meanwhile, the position calibration of the laser cutting machine can work normally without offset or error, and the process planning and parameters of the laser cutting machine are matched with the actual position of the workpiece, so that accurate cutting is allowed; for example, when the system determines that the machining position cannot match the originally set fixed position of the laser cutting machine, the system clamps the machined workpiece by using a preset clamping tool, corrects the machined workpiece from the machining position to the preset fixed position, performs cutting pretreatment on the machined workpiece, and the pretreatment process comprises periodically checking and maintaining a laser cutting head to ensure that the lenses, lenses and optical elements are clean and good in state, and can also use gas purging to keep the lenses clean.

In this embodiment, the step S4 of determining whether the to-be-cut content has a blurred cut point surface includes:

s41: collecting spectral characteristics in the content to be cut by using a preset spectrometer;

s42: judging whether the spectral features have preset marking features or not, wherein the marking features specifically comprise a specific wavelength peak value, wavelength offset and spectral width;

s43: if yes, analyzing the generation reason of the fuzzy cutting point surface based on the marking characteristics, and verifying according to the generation reason to obtain the improvement content of the fuzzy cutting point surface.

In this embodiment, the system collects spectral features in the content to be cut using a spectrometer that is preset, and then determines whether the spectral features have preset landmark features to execute corresponding steps; for example, when the system determines that the spectral features do not have the characteristic features, the system considers that the current processing workpiece does not have the potential problem, namely the processing workpiece does not have a fuzzy cutting point surface, and the processing workpiece does not need to be improved; for example, when the system determines that the spectral features have the characteristic features, the system analyzes the cause of the generation of the fuzzy cut point surface based on the characteristic features, and verifies the required content for improving the fuzzy cut point surface according to different generation causes.

In the spectrum analysis, the intensity change refers to a change in light intensity (or light signal intensity) at a specific wavelength in the spectrum, and when the system analyzes the spectral characteristics of the cut point surface, the following intensity changes should be noted:

peak intensity variation: the peaks in the spectrogram represent the maximum value of the optical signal intensity at a particular wavelength, which may result in an increase or decrease in peak intensity at certain wavelengths if there is a temperature anomaly or other problem during the cutting process, such a change may be an indicator of a temperature anomaly;

wavelength shift: an increase in temperature or other factors may cause a shift in the peak position in the spectrum, which can be observed by detecting a shift in wavelength across the spectrogram;

width variation: temperature variations may also cause variations in the width of the spectral line of the peak, and widening or narrowing of the spectral line may indicate variations in temperature or other factors.

Specific examples of the improvement content are as follows:

five-axis lasers need to ensure that the environment of the spectroscopic analysis is stable during operation, variations in temperature, humidity and air pressure can affect the spectral characteristics, analysis in a controlled laboratory environment can reduce these effects while using a stable light source, or periodically calibrating the light source to ensure its stability, avoid causing light intensity variations and wavelength shifts, and periodically calibrating the spectrometer to correct for wavelength shifts and peak intensity variations.

In this embodiment, a simulated focus track of a machined workpiece is constructed based on a preset focus node, and before step S1 of performing simulated cutting machining on the machined workpiece according to the simulated focus track, the method further includes:

s101: detecting surface parameters on the processed workpiece through capacitance ranging by using a preset sensor, wherein the surface parameters specifically comprise material thickness, workpiece flatness and workpiece flatness;

s102: judging whether the surface parameters meet the original cutting requirements of the processed workpiece or not;

s103: if yes, processing annotation is carried out on the processed workpiece according to the capacitance ranging, the content of the processing annotation is added to a pre-generated measurement report, and the measurement report is uploaded to a laser machine, wherein the processing annotation specifically comprises a measurement purpose, a measurement result and measurement uncertainty.

In the embodiment, the system detects surface parameters on the machined workpiece through capacitance ranging by applying a preset sensor, and then the system judges whether the surface parameters meet the original cutting requirements of the machined workpiece or not so as to execute corresponding steps; for example, when the system determines that the surface parameters cannot meet the cutting requirements, the system ensures that the calibration of the ranging device is accurate, if the device is inaccurate in calibration, measurement deviation can be caused, the surface of the processed workpiece is checked, flatness and cleanliness are ensured, no damage or foreign matters are caused, the accuracy of capacitance ranging is prevented from being influenced, and the stability of the environment in the measuring process is ensured, because the change of temperature, humidity and other environmental factors can influence the ranging result; for example, when the system determines that the surface parameters can meet the cutting requirements of the workpiece to be machined, the system performs machining annotation on the workpiece to be machined according to the capacitive ranging, the contents of the machining annotation comprise the purpose of capacitive ranging, the result of ranging completion and uncertainty existing in ranging, the machining annotation contents are added into a pre-generated measurement distance report, and the measurement distance report is uploaded to a five-axis laser machine, so that the five-axis laser machine can read various uncertainty machining contents existing in the workpiece to be machined at present, and the uncertainty machining contents are carefully machined.

In this embodiment, the step S2 of determining whether the trajectory deviation of the cutting beam occurs during the simulated cutting process includes:

s21: acquiring the temperature distribution of the cutting beam during cutting by using a preset thermal infrared imager;

s22: judging whether the temperature distribution has local temperature abnormality or not;

s23: if yes, detecting the vibration mode of the laser cutting head based on a preset vibration sensor on the laser cutting head.

In the embodiment, the system acquires temperature distribution on the surface of a processed workpiece when the five-axis laser machine is used for cutting by applying a preset thermal infrared imager, and then the system judges whether the temperature distribution has local temperature abnormality or not so as to execute corresponding steps; for example, when the system determines that there is no local temperature anomaly in the temperature profile, the system may consider a good indication that the cutting process is proceeding normally, which also means that the energy profile of the cutting beam is relatively uniform, no local anomalies occur, and the work piece may be continued to be processed without special corrective measures; for example, when the system determines that there is a local temperature abnormality in the temperature distribution, the system detects the vibration pattern of the laser cutting head based on a vibration sensor provided in advance on the laser cutting head, and since the abnormal vibration pattern is usually associated with abnormal movement or positional deviation of the cutting head or tool, by monitoring the vibration, the system can detect the deviation of the trajectory, thereby taking corrective measures in time, while the vibration sensor can help to improve the accuracy of the cutting quality control, by monitoring the vibration, it can be determined whether the cutting head moves along an intended path to ensure consistency of the cutting quality, and by monitoring the vibration of the cutting head or tool, any problems that cause inefficiency, such as tool wear or cutting speed mismatch, can be identified, which can help to optimize the production flow and improve the production efficiency.
