In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanying figures are described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Firstly, it should be understood that laser has the advantages of high energy density, directional light emission, high collimation and the like, and further, the processing surface is locally irradiated by laser, so that physical change or chemical change occurs on the processing surface, and finally a permanent mark is left on the surface, wherein a 3D galvanometer is generally applied to spatial pattern marking, such as circular arc surface laser marking, and a 2D galvanometer is generally applied to planar pattern marking, but limited by the cost consideration of the 3D galvanometer, some spatial pattern marking still can be performed by using the 2D galvanometer, but since a planar pattern is deformed in space, a large error often exists between the processing size and the theoretical size, for example, assuming that a square is to be marked on a circular arc surface of a cylinder by the 2D galvanometer, the pattern obtained by marking according to the existing scheme is roughly rectangular in shape, and since different focal depths of contour points of the square are different, the final pattern is difficult to meet the marking requirement of a user, so the current method for marking the precision of marking on a cylindrical surface by the 2D galvanometer.
In a first embodiment of the method for marking a cylindrical surface according to the present application, referring to fig. 1, the method for marking a cylindrical surface includes:
step S10, acquiring at least one marking point coordinate of a graph to be marked on a target cylindrical surface;
step S20, determining corresponding focal lengths of the marking points according to the coordinates of the marking points, wherein the focal lengths of the marking points are vertical distances between the marking points on the target cylindrical surface and the focal point of the target galvanometer;
in this embodiment, it should be noted that the graph to be marked is used to represent a graph to be marked, the graph to be marked is marked on a target cylindrical surface, the target cylindrical surface is a cylindrical surface selected by a user to mark the graph to be marked, a position on the target cylindrical surface where the graph is not marked exists, the marked graph may exist or may not exist on the target cylindrical surface, the cylindrical surface marking method is applied to a laser marking system, a movement component for cylindrical surface marking is controlled to move by an input/output signal of the laser marking system so as to mark the graph to be marked, the cylindrical surface marking system is arranged on an intelligent device, the intelligent device may be a computer or a personal PC, the cylindrical surface marking system may be provided with a graph drawing module or may not be provided with graph drawing software, for example, if the cylindrical surface marking system is provided with the graph drawing module, the intelligent device is a computer, and after the computer enters the marking system, the graph to be marked can be obtained automatically or based on manual operation of the user from graph drawing software installed on the computer.
Additionally, it should be noted that the process of the cylindrical surface marking system for marking the cylindrical surface may be understood as follows: the cylindrical surface marking system controls the 2D galvanometer to perform round-robin marking at a space designated position through an input/output signal until the marking of a graph to be marked is completed, wherein the input/output signal can be a signal of a certain designated marking point for marking and forming the graph to be marked, and can also be a signal of a certain designated marking area for marking and representing the graph to be marked, for example, in an implementable mode, the cross section direction of the cylindrical surface can be set to be the X-axis direction, the height direction of the cylindrical surface is the Y-axis direction, the direction of the central point of the 2D galvanometer, which is perpendicular to the cylindrical surface, is the Z direction, and the input/output signal is used for controlling the 2D galvanometer to move along X, Y and the Z axis so as to reach the space designated position.
Additionally, it should be noted that the coordinates of the marking points are used to represent the spatial positions of the marking points of the pattern to be marked on the target cylindrical surface, where the spatial positions may be represented by a preset spatial coordinate system, and the marking pattern obtained by marking the pattern to be marked on the target cylindrical surface is composed of a plurality of marking points, and the same marking pattern may also be presented differently due to the difference in the marking depth of focus, that is, the spatial position of each point needs to be determined when the pattern to be marked is marked, for example, the horizontal size presented by the pattern to be marked needs to be determined in the cross-sectional direction of the cylindrical surface in the three-dimensional coordinate system, the vertical size presented by the pattern to be marked needs to be determined in the height direction of the cylindrical surface, and the depth of focus presented by the pattern to be marked needs to be determined in the depth direction between the cylindrical surface and the 2D galvanometer.
Additionally, it should be noted that the focal distance of the marking point is a vertical distance between the marking point on the target cylindrical surface and the focal point of the target galvanometer, the smaller the focal distance of the marking point, the larger the marking focal depth, and the larger the focal distance of the marking point, the smaller the marking focal depth, for example, assuming that the user wants to mark a square with the same focal depth on the cylindrical surface, because the graph is a square with the same focal depthFor example, referring to fig. 2, fig. 2 is a schematic plane diagram showing a pattern to be marked and marked, wherein the preset spatial coordinate system is a three-dimensional coordinate system in which the cross-sectional direction of the target cylindrical surface is taken as an X-axis direction, the height direction of the target cylindrical surface is taken as a Y-axis direction, the direction in which the center point of the 2D galvanometer is perpendicular to the target cylindrical surface is taken as a Z-direction, the origin of the three-dimensional coordinate system is the initial marking point of the target galvanometer, the coordinate value is (0,0,0), 100 is a top view of the target cylindrical surface, 200 is a plan view of the target galvanometer, 300 is a marking point coordinate, 400 is an initial coordinate, 600 is a cross-sectional radius R of the target galvanometer, 500 is a distance between the center point of the target galvanometer and the cylindrical surface of the target, a is an angle between the marking point 300 and the cross-sectional radius 600 of the target cylindrical surface, b is an angle between the initial point and the cross-sectional radius 600, and the target cross-sectional radius can be set as an angle between the initial marking point of the target cylindrical surface 600 (X-axis) of the marking point) i ,y i ,z i ) The i may be a natural number, i corresponds to the marking points one to one, for example, i =1 represents a first marking point, i =2 represents a second marking point, a vertical distance from the starting point 400 to a center line of the target galvanometer is a transverse distance, when the 2D galvanometer is located at the same height and moves around the cylindrical surface, the 2D galvanometer may be considered to move around the X-axis direction, and when the 2D galvanometer moves in the height direction of the cylindrical surface, the 2D galvanometer may be considered to move around the Y-axis direction.
As an example, steps S10 to S20 include: acquiring marking point coordinates of at least one marking point of a graph to be marked on the target cylindrical surface under a preset space coordinate system; and determining a corresponding focal distance of the marking points according to the coordinates of the marking points, wherein the focal distance of the marking points is a vertical distance between the marking points on the target cylindrical surface and the focus of the target galvanometer.
The step of obtaining the coordinates of the marking points of the graph to be marked on the target cylindrical surface comprises the following steps:
step A10, acquiring initial coordinates of positioning points of the graph to be marked;
step A20, converting the initial coordinates of the positioning points into coordinates of marking points, wherein the coordinates of the marking points are used for representing the spatial positions of the marking points of the graph to be marked on the target cylindrical surface.
In this embodiment, it should be noted that, after the initial calibration point of the pattern to be calibrated is determined, any calibration point on the target cylindrical surface may be used as a positioning point, and then the coordinate value of the expanded view of the calibration point of the pattern to be calibrated on the target cylindrical surface and the coordinate value of the planar view of the pattern to be calibrated are converted, so that the pattern to be calibrated on the target cylindrical surface is completely consistent with the planar view of the pattern to be calibrated, where the initial coordinate of the positioning point is the initial coordinate value of the positioning point in the planar coordinate system, and the initial coordinate of the positioning point may be obtained by the cylindrical surface calibration system based on external graphic rendering software, or may be set by the cylindrical surface calibration system based on internal graphic rendering software.
As an example, steps a10 to a20 include: selecting a positioning point on the graph to be marked and extracting an initial coordinate of the positioning point; and converting the initial coordinates of the positioning points into coordinates of marking points, wherein the coordinates of the marking points are used for representing the spatial positions of the marking points of the graph to be marked on the target cylindrical surface.
Wherein, the step of converting the initial coordinates of the positioning point into coordinates of the positioning point comprises the following steps:
step B10, acquiring the cylindrical surface central point coordinate of the target cylindrical surface and the galvanometer central point coordinate of the target galvanometer;
step B20, determining the distance of the central point according to the coordinate of the central point of the cylindrical surface and the coordinate of the central point of the galvanometer;
and B30, calculating the coordinates of the marking points according to the central point distance and the initial coordinates of the positioning points.
In this embodiment, it should be noted that, because the expanded view of the cylindrical surface and the planar view of the cylindrical surface have an association relationship, it is further possible to convert the initial coordinates of the positioning points of the pattern to be marked into the coordinates of the marking points through the key points corresponding to the 2D galvanometer in the preset spatial coordinate system and the key points corresponding to the target cylindrical surface, where due to the spatial characteristics of the cylindrical surface, the ordinate of the marking point of the pattern to be marked on the planar view is consistent with the ordinate of the expanded view of the cylindrical surface, and further when the initial coordinates of the positioning points of the pattern to be marked are converted, the ordinate of the positioning points remains unchanged, that is, when the marking points parallel to the bus direction of the target cylindrical surface are marked on the target cylindrical surface, only the abscissa of the marking points is corrected, and the pattern to be marked according to the corrected coordinates can also meet the user requirements.
Additionally, it should be noted that the coordinates of the center point of the cylindrical surface are used to represent the coordinate values of the center point of the cylindrical surface under the preset planar coordinate system, the coordinates of the center point of the galvanometer are used to represent the coordinate values of the center point of the galvanometer under the preset planar coordinate system, the distance of the center point is used to represent the spatial distance between the center point of the cylindrical surface and the center point of the galvanometer under the preset planar coordinate system, and the coordinates of each marking point of the pattern to be marked can be transformed by inputting the distances of the center point of the cylindrical surface, the center point of the galvanometer and the center point into the preset coordinate transformation model, for example, in an implementable manner, assuming that the coordinates of the center point of the cylindrical surface are (x) m ,y m ) The coordinate of the central point of the galvanometer is (x) n ,y n ) Then the distance of the center point is
As an example, steps B10 to B30 include: acquiring a first coordinate value of the cylindrical surface central point of the target cylindrical surface and a second coordinate value of the galvanometer central point of the target galvanometer under a preset spatial coordinate system; calculating the center point distance by the first coordinate value and the second coordinate value; inputting the distance of the central point and the initial coordinates of the positioning point into a preset coordinate conversion model together to obtain coordinates of the marking point, wherein the preset coordinate conversion model is provided with a coordinate conversion formula, and the coordinate conversion formula is as follows:
y 2 ＝y 1
wherein (x) 1 ,y 1 ) As the initial coordinates of the positioning point, (x) 2 ,y 2 ) And D, calculating the coordinate of the marking point, wherein L is the distance of the central point, and R is the section radius of the target cylindrical surface.
Before the step of obtaining the initial coordinates of the positioning points of the graph to be marked, the method for marking the cylindrical surface further comprises the following steps:
step C10, acquiring a graph to be marked input by a user, wherein the graph to be marked comprises at least one marking simulation point;
and step C20, selecting the positioning point simulation coordinates of the simulation positioning points from the calibration simulation points as the positioning point initial coordinates.
In this embodiment, it should be noted that the marking simulation point is used to represent a point on a simulation graph simulating a graph to be marked on a graph drawing software, the selected simulation positioning point is used to represent any marking simulation point forming the simulation graph, the positioning point simulation coordinate is a coordinate value of the simulation positioning point, and after a certain simulation positioning point is selected, the point can be used as the marking positioning point 0 ,y 0 ) Then (x) 0 ,y 0 ) Can be used as the initial coordinates of the positioning point.
As an example, steps C10 to C20 include: acquiring a to-be-marked graph input by a user on a preset marking interface, wherein the preset marking interface is arranged on the intelligent device, the user can draw the to-be-marked graph on the preset marking interface in real time, and the existing to-be-marked graph can also be acquired on the preset marking interface through dragging or pressing and other instruction triggering, and the to-be-marked graph comprises at least one marking simulation point; and selecting the coordinate value of a simulated positioning point from the calibration simulation points as the initial coordinate of the positioning point.
Wherein, the step of determining the corresponding focal distance of the marking point according to the coordinates of each marking point comprises the following steps:
d10, calculating a focal depth correction parameter of at least one marking point on the cylindrical surface according to the coordinates of each marking point;
and D20, correcting the focal length of the galvanometer of the corresponding marking point according to each focal depth correction parameter to obtain the focal length of each marking point.
In this embodiment, it should be noted that, after coordinate conversion is performed on a calibration point on a pattern to be calibrated through a preset coordinate conversion model, laser emitted by a target galvanometer can accurately reach the calibration point required by a user, however, due to different focal distances of the target galvanometer, focal depths of different calibration points need to be corrected in order to ensure calibration accuracy, so that a focal depth correction parameter is used for correcting the focal depth, when a focal length of the galvanometer is smaller, a calibration pattern is smaller, and a calibration pattern is larger when the focal length is larger, which is indispensable for correcting a plane of the 2D galvanometer and a Z axis under a spatial coordinate system.
Additionally, it should be noted that the effective Z-axis value range of the graph to be marked on the target cylindrical surface is ± Z 0 Taking the Z-axis coordinate of the central point as a reference, and the focal length of the central point is H 0 Measuring the size of the pattern to be marked
And
if Z is i If the Z axis position of the ith marking point is more than 0 (the Z axis position of the ith marking point is less than the central focal length), the Z is determined 0 Is divided equally by length n to determine Z i If m < Z i If m +1, Z is determined by interpolation i Wherein 0 < m < n-1,m has an actual width value of
The actual width value of m +1 is
Further according to Z i And H 0 The width value ratio of fsx to fsy, that is, the focal depth correction parameter calculation formula is as follows:
finally, the corrected coordinates (x ', y ') of the calibration point are obtained, wherein x ' = x i *fsx，y′＝y i *fsy。
As an example, steps D10 to D20 include: determining a Z-axis width value corresponding to each marking point according to the corresponding relation between the coordinate of each marking point and the effective Z-axis value range, and calculating a focal depth correction parameter of at least one marking point on the cylindrical surface according to each Z-axis width value; and correcting the focal length of the galvanometer of the corresponding marking point according to each focal depth correction parameter to obtain the focal length of each marking point.
And S30, controlling the target galvanometer to mark the graph to be marked on the target cylindrical surface according to the focal length of each marking point and the coordinate of each marking point.
As an example, step S30 includes: and sequentially controlling the target galvanometer to mark each marking point according to at least one control signal corresponding to the focal length of each marking point and the coordinate of each marking point, so as to mark the graph to be marked on the target cylindrical surface, wherein the control signal is used for controlling the target galvanometer to move to a spatial position corresponding to the marking point and mark the graph.
The step of controlling the target galvanometer to mark the graph to be marked on the target cylindrical surface according to the focal length of each marking point and the coordinate of each marking point comprises the following steps:
e10, generating at least one positioning control signal according to the coordinates of each marking point and the corresponding focal length of the marking point;
and E20, controlling the target galvanometer to mark the graph to be marked on the target cylindrical surface according to the positioning control signals and the corresponding marking control signals.
In this embodiment, it should be noted that, in the marking process, because the subjective and objective factors may have a situation that the pattern to be marked needs to be changed, a positioning control signal may be generated when correcting the focal length of each marking point and the coordinates of each marking point of the pattern to be marked, where the positioning control signal is used to position the target galvanometer at a spatial position corresponding to the marking point, the marking control signal is used to control the target galvanometer to perform marking, and the marking control signal may be triggered by a marking control operation performed by a user on the marking system, that is, the marking is performed not automatically after correction, but according to the marking control operation of the user, so that the flexibility of marking the cylindrical surface is improved while the marking accuracy is ensured.
As an example, steps E10 to E20 include: converting the coordinates of each marking point and the corresponding focal length of the marking point into corresponding positioning control signals according to a preset signal conversion format, wherein the preset signal conversion mode can be set according to the requirements of a user; and responding to the marking control operation of a user, acquiring marking control signals corresponding to the positioning control signals, and sequentially executing the marking control signals to mark the graph to be marked on the target cylindrical surface based on the target galvanometer.
The embodiment of the application provides a cylindrical surface marking method, namely, at least one marking point coordinate of a graph to be marked on a target cylindrical surface is obtained; determining a corresponding focal distance of the marking points according to the coordinates of the marking points, wherein the focal distance of the marking points is a vertical distance between the marking points on the target cylindrical surface and the focus of the target galvanometer; and controlling the target galvanometer to mark the graph to be marked on the target cylindrical surface according to the focal length of each marking point and the coordinate of each marking point. Because the coordinate of the marking point is the coordinate of the graph to be marked on the cylindrical surface, and the focal length of the marking point is the distance between the marking point on the cylindrical surface and the target galvanometer, the coordinate of the marking point and the focal length of the marking point can completely reflect the actual position of the marking point on the cylindrical surface, namely, the aim of accurately positioning the marking point on the cylindrical surface is fulfilled, and the method does not depend on the actual position of the marking point on the plane when the graph is marked on the cylindrical surface through the 2D galvanometer, so the technical defect that the machining size and the theoretical size have deviation due to the deformation of the plane graph on the space is overcome, and therefore, the marking precision of marking on the cylindrical surface through the 2D galvanometer is improved.
Example two
Further, referring to fig. 3, in another embodiment of the present application, the same or similar contents as those in the first embodiment may refer to the above description, and are not repeated herein. On this basis, the step of controlling the target galvanometer to mark the pattern to be marked on the target cylindrical surface according to the positioning control signals and the corresponding marking control signals further comprises:
step F10, responding to the cylindrical surface marking planning operation on a preset marking interface, and acquiring the graphic marking path planning information of the graphic to be marked;
step F20, according to the graphic marking path planning information, performing a strategy for matching signals for each positioning control signal and the corresponding positioning control signal together;
and F30, executing each positioning control signal and the corresponding marking control signal according to the signal execution strategy so as to mark the graph to be marked on the target cylindrical surface based on the target galvanometer.
In this embodiment, it should be noted that, for different patterns to be marked, visualization effects of the patterns to be marked are different, and further, by freely setting the pattern marking path planning information, a user can avoid marking risks in the marking process, for example, assuming that the pattern a to be marked is marked by the marking path 1, the user needs to perceive whether marking is abnormal or not when the pattern to be marked is marked to 3/4, and marking is performed by the marking path 2, the user only needs to perceive whether marking is abnormal or not when the pattern to be marked is marked to 1/4, and further, the marking path 2 can avoid time cost and consumable cost consumed in the marking process because marking is not up to standard, so the pattern marking path planning information is used for planning the marking path for the pattern to be marked, for example, assuming that the pattern to be marked is rectangular, four corners are A1, A2, A3, and A4, the pattern marking path may be A2 → A3, and the signal execution strategy is used for executing the pattern marking → A1.
As an example, steps F10 to F30 include: responding to a cylindrical surface marking planning operation on a preset marking interface, and acquiring graphic marking path planning information of the graphic to be marked, wherein the cylindrical surface marking planning operation can be triggered by voice or key operation input by a user on the preset marking interface; according to the graph marking path planning information, matching a signal execution strategy for each positioning control signal and the corresponding positioning control signal together; and executing each positioning control signal and the corresponding marking control signal according to the signal execution strategy so as to mark the graph to be marked on the target cylindrical surface based on the target galvanometer.
The embodiment of the application provides a galvanometer marking control method, namely, the method comprises the steps of responding to cylindrical surface marking planning operation on a preset marking interface, and obtaining graphic marking path planning information of a graphic to be marked; according to the graph marking path planning information, matching a signal execution strategy for each positioning control signal and the corresponding positioning control signal together; and executing each positioning control signal and the corresponding marking control signal according to the signal execution strategy so as to mark the graph to be marked on the target cylindrical surface based on the target galvanometer. Compared with the method for marking the graph to be marked according to the preset default marking path, the method and the device for marking the graph to be marked have the advantages that the graph to be marked is matched with the marking path based on the graph marking path planning information, the strategy is executed according to the signal corresponding to the graph marking path, the target galvanometer is controlled to mark the graph to be marked on the target cylindrical surface, the purpose that different graph marking paths are set for different graphs to be marked can be achieved, the visualization effect of different graphs to be marked is different, the graph planning path is set in a targeted mode, the marking risk in the marking process can be avoided, and therefore the foundation is laid for improving the marking accuracy of marking on the cylindrical surface through the 2D galvanometer.
