In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Referring to fig. 2, fig. 2 is a first embodiment of a control method of the laser ablation system of the present invention, the method comprising the steps of:
step S10, acquiring a 3D contour map of a device to be processed, and determining workpiece information of the device to be processed according to the 3D contour map, wherein the workpiece information comprises the gradient of a salient point of a curved surface to be deeply stripped and the relative position of the salient point in the device to be processed.
In the embodiment, the device to be processed is ablated by laser to realize the stripping of the salient points of the device to be processed, and the 3D line laser camera in the laser ablation system can be controlled to perform the acquisition of the 3D contour map. Specifically, spatial information of a device to be processed is collected into image and coordinate point information through X3 linear module scanning and a D line laser camera, wherein the 3D line laser camera is used for collecting spatial structure information of the device to be processed so as to obtain a corresponding 3D contour map, two-dimensional coordinates (Y, Z) or (X, Z) of the device to be processed can be obtained in a static state, and the 3D line laser can scan the whole surface to obtain three-dimensional coordinates (X, Y, Z) through movement of a movement axis.
Optionally, the control device of the laser ablation system includes a light path portion, an X3 linear module, a 3D distance measuring device, a DD motor, a jig (2X), a power measuring assembly, a scanning gun assembly 2X, a dust extraction assembly, an X1Y1, and an X2Y2 lead screw module 2X.
Alternatively, when scanning a convex object, the camera cannot acquire data of one of the corners due to the occlusion, and therefore invalid data is generated, which is called a shadow area, which means that a part of the 3D data points is lost. For example, the detection requirements of automobile connectors are more and more strict, and the uneven pins cause poor contact, which directly affects the production and manufacture of automobiles. In order to ensure efficient and economical production, it is necessary to quickly and accurately test the quality of the automotive connector. A single-head sensor based on the principle of the laser triangulation method has a blind area when scanning a PIN needle, and aiming at the problem, the connector needs to be scanned for many times and image splicing is carried out, so that the detection can be accurately finished. In order to solve this problem and reduce the cycle time, another camera may be provided to have a working angle symmetrical to that of the first camera, ensuring that the target area can be recognized even if the first camera is blocked, thereby preparing a dual head sensor. The double-head sensor can complete 3D scanning through one-time scanning, and no data point is omitted. The result is a shadow-free scan, with improved accuracy and line speed by excellent 3D imaging of the entire part. From the 3D imaging effect, shadow areas can appear in the scanning of the single-head camera, and the double-head camera can form images without blind areas.
And step S20, determining the ablation times according to the gradients of the salient points, and generating at least two contour lines when the ablation times are larger than a preset value, wherein the gradient of the contour line at the lowest layer is smaller than or equal to a preset gradient.
In this embodiment, the above-mentioned bump is the bump on the device to be processed, and the gradient of bump is the gradient from the horizontal plane of the curved surface to be peeled to the bump peak, when the gradient of bump is great, if want to omit the dull polish process, can set up the number of times of ablation as many times, wherein, only when melting for the last time, will correspond to wait to peel the dark region and set up less gradient, can make to melt for the last time and not carry out under the condition of dull polish process like this, peel dark effect and be equal to the curved surface after the dull polish, for example: when the laser ablation system is controlled to ablate the salient points, if the gradient does not meet the condition of completing one-time ablation, the ablation can be judged to be carried out for a plurality of times, namely, the number of times of ablation is a plurality of times.
Optionally, the number of times of ablation is determined according to the gradient of the salient point, and when the number of times of ablation is greater than a preset value, contour lines corresponding to the preset value are generated.
Optionally, when the gradient of the salient point is greater than the preset gradient, determining that the number of times of ablation is two, and generating two contour lines. When the ablation frequency is judged to be one time, the salient points can be deeply stripped only by ablation once, and the frosted effect is achieved, so that a contour line is generated to limit an ablation target area of a laser ablation system, wherein the target area is the salient points; similarly, when the number of times of ablation is determined to be two, the frosting effect cannot be realized only by once ablation, and the frosting effect can be realized only by twice ablation of the salient points, so that two contour lines are generated to limit the target area of each ablation for the laser ablation system.
Optionally, when the gradient of the bump is greater than the preset gradient, determining the height of the bump and obtaining a preset offset. And determining the ablation times according to the preset offset and the height of the salient points, and generating contour lines with the number corresponding to the preset value when the ablation times are larger than the preset value.
In this embodiment, if only the gradient of the to-be-deep-stripped region corresponding to the last ablation is considered, and the maximum deep-stripped thickness that can be achieved by the laser ablation system is not considered, if the to-be-processed device bump still has a certain height after the target region of the last ablation is removed, and if the number of times of ablation is not controlled according to the height of the bump, a mechanical fault is likely to occur, therefore, the number of times of ablation suitable for other regions is determined according to the height of the bump while ensuring that the gradient of the target region of the last ablation is less than or equal to the preset region, and the ablation stability of the laser ablation system can be improved.
And step S30, performing successive ablation treatment on the salient points in the device to be processed based on the contour lines and the relative positions.
In the technical scheme of this embodiment, the control device of the laser ablation system may determine the ablation times according to the gradient of the convex points of the curved surface to be deeply stripped, then determine the contour lines according to the ablation times, and ablate the device to be processed based on the contour lines, where the gradient of the generated lowest contour line is smaller than the preset gradient, and the region to be deeply stripped corresponding to the lowest contour line is the target of the last ablation, that is, the gradient of the region to be ablated at the last time is smaller than the preset gradient, and the convex points of the preset gradient are ablated, and the device to be processed after being deeply stripped can be obtained without ablating the device to be processed with the ground power.
Referring to fig. 3, fig. 3 is a second embodiment of the control method of the laser ablation system of the present invention, and based on the first embodiment, step S30 includes:
and step S31, determining the height distance corresponding to each contour line.
In this embodiment, the height difference between adjacent contour lines on the topographic map is called the contour pitch, also called the contour pitch (interval), and is denoted by h. On the same topographic map, the contour lines have the same height distance. The smaller the interval of the contour lines with equal height distances is, the more detailed the change condition of the ground can be represented; the larger the equal height distance is, the more simple the ground is represented on the map; however, when the height interval is too small, the contour lines on the topographic map are too dense, which affects the definition of the map surface, and the amount of the surveying and mapping work increases, which takes a longer time. When a topographic map is mapped, according to the actual situation, a proper equal-altitude distance is selected according to the size of a map scale and the terrain of a survey area, and the equal-altitude distance is called as a basic equal-altitude distance. Furthermore, the map with a large scale has small reduction degree, detailed landform representation and small equal-height distance; on a map with a small scale, the landform representation is rough, and the equal-height distance needs to be increased. On the other hand, although the map has the same scale, the size of the equal altitude distance may be different depending on the content of the map and the fluctuation of the terrain.
Optionally, determining the height of the bump; and taking the height difference between the contour line of the uppermost layer and the salient point as the corresponding contour distance of the contour line of the uppermost layer, and taking the height difference between each of the rest contour lines and the adjacent contour line of the upper layer as the corresponding contour distance, so as to obtain the contour distance corresponding to each contour line.
And step S32, determining the ablation power corresponding to each ablation according to the gradient and the equal height distance corresponding to each contour line.
In this embodiment, the control device of the laser ablation system stores mapping tables of gradient, equal-height distance and power in advance, and when the gradient and the equal-height distance of the region to be ablated are determined, the ablation power can be determined.
And step S33, carrying out successive ablation treatment on the salient points in the device to be processed according to the ablation power and the relative position.
In the technical scheme of this embodiment, the salient points are divided into different areas through the contour lines to be ablated by the laser ablation system, so that the gradient of the to-be-ablated area corresponding to the contour line at the lowest layer can be ensured to be in a preset gradient, the sanding process for the last ablation treatment is not needed, and the ablation efficiency of the salient points of the to-be-processed device is improved.
Referring to fig. 4, fig. 4 is a third embodiment of the control method of the laser ablation system according to the present invention, based on any one of the first to second embodiments, after step S10, the method further includes:
and step S50, when the gradient of the salient point is equal to the preset gradient, carrying out ablation treatment on the salient point in the device to be processed according to a first preset ablation power.
In this embodiment, the first preset ablation power is preset ablation power associated with a preset gradient, and ablation depth of the bumps with the preset gradient can be achieved by performing ablation with the first preset ablation power.
In the technical scheme of this embodiment, when it is determined that the gradient of the salient point of the to-be-processed device is equal to the preset gradient, it is determined that the salient point is subjected to primary ablation through the first preset ablation power, and the sanding process is not required, so that the stripping efficiency of the salient point of the to-be-processed device can be improved.
Referring to fig. 5, fig. 5 is a fourth embodiment of the control method of the laser ablation system according to the present invention, based on any one of the first to third embodiments, after step S10, the method further includes:
and step S60, when the gradient of the salient point is smaller than the preset gradient, determining the height of the salient point.
And step S70, acquiring a second preset ablation power corresponding to the height and the gradient of the salient point.
And step S80, carrying out successive ablation treatment on the salient points in the device to be processed according to the second preset ablation power and the relative position.
In this embodiment, the control device of the laser ablation system stores a mapping table of the height and the gradient of the bump in advance, and after the value of the to-be-stripped depth is determined, the second preset ablation power can be determined based on the height and the gradient of the bump.
In the technical scheme of the embodiment, when the gradient of the detected convex point is smaller than the preset gradient, the convex point can be judged to be stripped through one-time ablation, so that the stripping of the convex point of the device to be processed can be completed by determining a corresponding second preset ablation power based on the height and the gradient of the convex point and performing ablation without sanding.
