[0002] In a laser processing application scenario, the common edge line often has the phenomenon of thermal deformation caused by adjacent edge processing. After thermal deformation, depending on the specific form of deformation, without special treatment on the common edge line, referring to ordinary processing edges, the problem of laser cutting head lens contamination will occur (the plate generally needs to be pierced before cutting, and there is space to blow down the slag after piercing, and direct cutting will cause contamination of the protective lens due to the slag).

[0060] The technical solutions in the embodiments of the present invention will be apparently and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all the embodiments. Based on the embodiments in the present invention, all the other embodiments obtained by those of ordinary skill in the art without any creative work, fall within the scope of protection of the present invention.

[0061] The terms "first", "second", "third", "fourth" and the like (if any) in the description, claims, and drawings of the present invention are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present invention described herein can be implemented in other than the order illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a list of steps or units does not necessarily limit to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to such processes, methods, products, or devices.

[0062] The technical solutions of the present invention will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in some embodiments.

[0063] Reference is made to Figure 1 The application provides a laser cutting method based on detection of common edge perforation, comprising:

[0064] S1: obtaining a first common edge line of a workpiece to be cut, the first common edge line representing an edge line commonly used by adjacent workpieces, and there is no perforation setting on the first common edge line on a drawing of the workpiece to be cut;

[0065] S2: performing common edge perforation detection on the first common edge line;

[0066] S3: based on the result of the common edge perforation detection, perforating and / or cutting the first common edge line.

[0067] In one embodiment, reference is made to Figure 6 When there are two adjacent processing patterns in the workpiece to be cut 5 and the result of the common edge perforation detection is to cut the first common edge line 501, the number of the first common edge line 501 is 1, and only cutting along the first common edge line 501 is needed to obtain two adjacent workpieces.

[0068] In another embodiment, reference is made to Figure 7 When there are two adjacent processing patterns in the workpiece to be cut 5 and the result of the common edge perforation detection is to cut and perforate the first common edge line 501, the number of the first common edge line 501 is 1, and there are several perforations 502 on the first common edge line; specifically, when the number of perforations 502 is 4, the first common edge line 501 is divided into 3 first common edge line segments, at this time, the cutting head needs to cut along the first common edge line for 3 times and perforate for 4 times.

[0069] Of course, it should be realized that the application is not limited thereto, and other numbers of perforations are within the protection scope of the application.

[0070] Specifically, when the number of perforations 502 is N, the first common edge line 501 is divided into N-1 first common edge line segments, at this time, the cutting head needs to cut along the first common edge line for N-1 times and perforate for N times; wherein N is a positive integer.

[0071] In other embodiments, reference is made to Figure 8 When there are six adjacent processing patterns in the workpiece to be cut 5 and the result of the common edge perforation detection is to cut and perforate the first common edge line 501, the number of the first common edge line 501 is 3, and there are 3 perforations 502 on each of the first common edge lines, i.e., each of the first common edge lines is divided into 2 first common edge line segments, at this time, the cutting head needs to cut along each of the first common edge lines for 2 times and perforate for 3 times.

[0072] Of course, it should be realized that the present application is not limited thereto, and other numbers of machining patterns in the workpiece to be cut and numbers of first co-edges are within the protection scope of the present application.

[0073] In the above scheme, through co-edge hole detection, it can be judged whether the current co-edge needs to be perforated, and cutting or perforation is performed based on the judgment result, thereby avoiding the problem of reduced manual processing efficiency, and further increasing the processing accuracy and safety. In addition, after perforating the co-edge, the machining swarf generated in the subsequent cutting process can be dropped through the perforation, thereby avoiding pollution of the lens and affecting the cutting of the cutting head, and further improving the processing efficiency.

[0074] In a preferred embodiment, please refer to Figure 2 Before the first co-edge of the workpiece to be cut is obtained, it includes:

[0075] S01: Obtain the drawing of the workpiece to be cut to obtain the co-edges on the drawing;

[0076] S02: Determine whether there is a hole setting on the co-edges on the drawing; if yes, determine that the co-edges are not the first co-edges; if no, determine that the co-edges are the first co-edges.

[0077] In a specific embodiment, the hole setting on the co-edges on the drawing represents that the user has set the hole before cutting; when there is a hole setting on the co-edges on the drawing, the co-edges are determined to be the second co-edges, and the second co-edges are perforated and / or cut based on the drawing set by the user.

[0078] In the above scheme, before the co-edges are obtained, the co-edges on the drawing of the workpiece to be cut are obtained to determine whether the co-edges on the drawing already have a hole setting; if the hole setting already exists, cutting or perforation is performed based on the hole setting on the drawing; if the hole setting does not exist, hole detection is performed; thereby further improving the processing efficiency.

[0079] Regarding hole detection, in a preferred embodiment, please refer to Figure 3 The co-edge hole detection on the first co-edges includes:

[0080] S21: Determine the detection parameters of the co-edge hole detection to generate a hole detection instruction;

[0081] S22: Execute the hole detection instruction to detect the first co-edges to obtain a hole detection result;

[0082] S23: Based on the hole detection result, obtain a digital signal within a plurality of periods;

[0083] S24: based on the digital signal, determining to perforate or cut the first common edge line.

[0084] As to the period, in an embodiment, the number of the period is 20.

[0085] Of course, it should be realized that the present application is not limited thereto, and other numbers of the period are within the protection scope of the present application. As to the detection parameter, in an embodiment, the detection parameter includes height, light output power, light output frequency, duty cycle, focal point, air pressure, and plate collision delay time.

[0086] In a specific embodiment, the height in the detection parameter includes 4mm, the light output power is 4800w, the light output frequency is 2000Hz, and the duty cycle is 10%.

[0087] In the plate collision delay time, when the cutting head detects the collision with the processing plate, the cutting head is controlled to continue processing or stop processing after a delay.

[0088] In a preferred embodiment, as to the perforation detection, the present application can also use an infrared camera UM-301 and a near-infrared light source to collect images, through analyzing the infrared images collected by the infrared CCD camera, based on the characteristics of low signal-to-noise ratio and poor contrast of the infrared images themselves, the collected infrared images are subjected to noise removal by using median filtering, and then the contrast of the images is enhanced by using gray linear enhancement, finally, the images are segmented by using a segmentation method based on fuzzy theory, and in the region of interest (i.e. the first common edge line), the features are used to realize recognition and positioning (i.e. determining the need for perforation or cutting).

[0089] In another preferred embodiment, as to the perforation detection, the present application can also change the height of the cutting head (i.e. the up and down movement of the cutting head) to determine whether there is a perforation on the plate, and then determine whether perforation is needed through plate collision detection.

[0090] In other preferred embodiments, as to the perforation detection, the present application can also shoot the first common edge line by using an industrial camera, and then determine whether perforation is needed through visual detection.

[0091] In the above scheme, since the machining debris is splashed to the cutting head during the cutting process, the machining debris can be detected by the cutting head, and the machining debris is misjudged as the machining plate, and the cutting is stopped. However, the machining debris does not affect the cutting at this time, and if the cutting is frequently stopped, the cutting efficiency will be reduced. The present application increases the judgment time by setting the plate collision delay time. If the cutting head can still detect the machining plate after the plate collision delay, the machining is stopped. If the cutting head cannot detect the machining plate after the plate collision delay time, the machining is continued, which ensures the continuity of the machining and improves the machining efficiency.

[0092] Regarding the determination of the cutting mode, in one preferred embodiment, the determining, based on the digital signal, to perforate or cut the first common side includes:

[0093] Based on the digital signal, it is determined whether the following first condition is met:

[0094] The maximum value of the digital signal in any period is above a first preset threshold; or

[0095] The difference between the maximum value and the minimum value of the digital signal in all periods is above a second preset threshold;

[0096] If yes, it is determined that the first common side needs to be perforated.

[0097] Wherein, above the first preset threshold includes the case of equal to the first preset threshold; above the second preset threshold includes the case of equal to the second preset threshold.

[0098] In other preferred embodiments, the determining, based on the digital signal, to perforate or cut the first common side further includes:

[0099] Based on the digital signal, it is determined whether the following second condition is met:

[0100] The maximum value of the digital signal in any period is less than the first preset threshold; and

[0101] The difference between the maximum value and the minimum value of the digital signal in all periods is less than the second preset threshold;

[0102] If yes, it is determined that the first common side needs to be cut.

[0103] In one embodiment, the first preset threshold includes 3800, and the second preset threshold is 100.

[0104] Of course, it should be realized that the present application is not limited thereto, and other preset threshold values are within the protection scope of the present application.

[0105] Specifically, please refer toFigure 9 , Figure 9 is a waveform diagram of a digital signal based on a plane rectangular coordinate system, wherein the X-axis is time, the unit is m:s:ms; the Y-axis is light intensity, wherein the light intensity of the Y-axis is characterized as the light intensity value converted into an analog voltage signal; the waveform b is a digital signal waveform in the perforation mode, the maximum value of the digital signal waveform b is about 1500, the minimum value of the digital signal waveform b is about -40, that is, the difference between the maximum value and the minimum value of the digital signal is about 1540, and further the difference between the maximum value and the minimum value of the digital signal waveform b is determined to be above 100, which satisfies that the difference between the maximum value and the minimum value of the digital signal in all periods in the first condition is above the second preset threshold value, and thus it is determined that the first common edge line needs to be perforated.

[0106] In other embodiments, please refer to Figure 10 , Figure 10 is a waveform diagram of a digital signal, wherein the waveform b is a digital signal waveform in the cutting mode, since the digital signal waveform b is a straight line waveform, it is equivalent that the maximum value and the minimum value of the digital signal are both -40, and the difference between the maximum value and the minimum value of the digital signal is 0, that is, it simultaneously satisfies that the difference between the maximum value and the minimum value of the digital signal in all periods in the second condition is less than the second preset threshold value 100 and the maximum value of the digital signal in any period is less than the first preset threshold value 3800.

[0107] In other embodiments, by detecting the dispersion of the digital signal return value, for example, by comparing the variance size to judge whether perforation or cutting is needed.

[0108] In specific embodiments, before determining to perforate or cut the first common edge line based on the digital signal, it further includes:

[0109] determining a first light output parameter for perforating the first common edge line and a second light output parameter for cutting the common edge line.

[0110] Specifically, the first light output parameter and the second light output parameter each include height, light output power, light output frequency, duty cycle, focal point, air pressure, and plate collision delay time.

[0111] In an embodiment, the height in the detection parameter, the first light output parameter, and the second light output parameter includes a user-defined height, a highest-level perforation height, and a cutting height; wherein the user-defined height is a user-defined input height, the highest-level perforation height is the perforation height of the highest level in multi-level perforation, and the cutting height is the height of the cutting head in the cutting process; specifically, the height parameter adopts the user-defined height, 4mm.

[0112] In another embodiment, the focus in the detection parameter includes: a custom focus and a detection focus; when the custom focus is used, the focus set by the user is adopted; when the "cutting focus to zero focus offset" is used, an offset of a set amount from the cutting focus to the zero focus is adopted as the detection focus; specifically, the detection focus is only the focus during detection, and when other actions such as perforation and cutting are performed after detection, the focus is changed to the focus of the corresponding process.

[0113] In other embodiments, the air pressure includes: a cutting air pressure and a custom air pressure; when the co-edge perforation detection is performed, the air needs to be opened in advance, that is, the air pressure in the cutting process or the air pressure set by the user is adopted.

[0114] Of course, it should be realized that the present application is not limited thereto, and other values of the height parameter, the focus parameter, and the air pressure parameter are within the protection scope of the present application.

[0115] For the acquisition of the digital signal, please refer to Figure 4 In a preferred embodiment, the co-edge perforation detection is light emission detection, and the result of the perforation detection includes a light feedback signal; and the obtaining of the digital signal in a plurality of periods based on the result of the perforation detection includes:

[0116] S231: acquiring a light intensity of the light feedback signal and converting the light intensity into an analog voltage signal;

[0117] S232: converting the analog voltage signal into an original digital signal based on analog-digital conversion;

[0118] S233: filtering the original digital signal to obtain the digital signal.

[0119] In an embodiment, please refer to Figure 9 and Figure 10 , Figure 9 and Figure 10 are digital signal waveform diagrams in a perforation mode or a cutting mode, wherein the digital signal waveform a is the digital signal waveform before filtering, and the digital signal waveform b is the digital signal waveform after filtering; it can be seen that the waveform after filtering reduces noise and presents a clearer waveform, thereby improving the accuracy of the comparison between the waveform and the preset threshold.

[0120] In the above scheme, before determining to perforate or cut the first co-edge line, the maximum value and the minimum value of the digital signal are judged based on the first preset threshold and the second preset threshold, and the digital signal is filtered before the judgment, thereby further ensuring the accuracy of the cutting or perforation.
