[0047] In order to make the persons skilled in the art better understand the scheme of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings.

[0051] The server 105 can be a server providing various services, for example, a background server providing support for a page displayed on the terminal device 101, 102, 103.

[0052] It should be noted that the cutting calibration method provided in the embodiments of the present application is generally executed by a server / terminal device, and accordingly, the cutting calibration apparatus is generally arranged in the server / terminal device.

[0053] It should be understood that Figure 1 The number of terminal devices, networks and servers in

[0054] With reference to Figure 2 , a flow chart of one embodiment of the cutting calibration method according to the present application is shown. The cutting calibration method includes the following steps:

[0055] In step S201, the length of the identification area of the cutting piece 30 and preset cutting data are acquired, wherein the cutting piece 30 has at least two cutting identifications, and the preset cutting data includes a preset cutting number and a preset identification interval between two adjacent cutting identifications.

[0056] In the present embodiment, the length of the identification area is represented as the distance between the starting cutting identification and the ending cutting identification in the cutting piece 30 (for the calculation method of the length of the identification area, please refer to the description below).

[0057] The cutting identification plays a role of positioning in the actual cutting process, wherein the cutting identification can be an identification point 31; for example, Figure 3 For example, Figure 3 is a schematic view of the cutting piece 30, wherein the mark 30 is the cutting piece 30, the mark 31 is the identification point 31, the mark 32 is the cutting path 32, and the mark 33 is the cutting area 33. Figure 3 As can be seen, the cutting piece 30 has a plurality of identification points 31, all the identification points 31 in the same column form a cutting path 32, and the cutting area 33 is between two adjacent cutting paths 32, and at this time, the length of the identification area is the distance between the first cutting path 32 and the last cutting path 32.

[0058] In addition, the length of the marked area can also be the distance between the first and last marked points in the same row; however, due to the processing technology, the straight line connecting the first and last marked points in the same row on the actual workpiece to be cut may be inclined to the horizontal line. Therefore, the accuracy of "the marked area length calculated based on the first and last marked points in the same row" is lower than that of "the marked area length calculated based on the first and last cutting tracks".

[0059] It should be noted that the above-mentioned cutting mark can also be a marking line, which is the cutting path 32 in the example of "cutting mark is marking point 31" above.

[0060] The aforementioned preset number of cuts represents the number of cuts required for the workpiece 30 to be cut. This preset number of cuts is stored in a preset database and can be retrieved from the database. Figure 3 For example, in Figure 3 If three products need to be cut from the 30 pieces to be cut, then the preset number of cuts is 3.

[0061] The aforementioned preset marking interval represents the interval between two adjacent cutting markings; Figure 3 For example, the preset marking interval is the first cutting line 32 (i.e. Figure 3 The distance between the leftmost cutting track 32 and the second cutting track 32 is also the distance between the first marker point 31 and the second marker point 31 in the same row. However, the accuracy of "the preset marker interval calculated based on the first cutting track 32 and the second cutting track 32" is higher than that of "the preset marker interval between the first marker point 31 and the second marker point 31 in the same row".

[0062] Step S202: Calculate the marker offset parameter based on the marker area length, the preset number of cuts, and the preset marker interval.

[0063] In this embodiment, the aforementioned marker offset parameter represents the offset of two adjacent cutting markers on the workpiece 30 to be cut relative to a preset marker interval; continuing with... Figure 3 For example, the cutting marker at this time is cutting point 31, such as the first cutting point 31 (i.e. Figure 3 The leftmost cutting point 31) and the last cutting point 31 (i.e. Figure 3 The distance between the rightmost cutting point 31 is 2.1, the preset mark interval is 2, and the mark offset parameter is the difference between 2.1 and 2, which is 0.1.

[0064] Step S203: Calibrate the position of the cutting mark to be calibrated in the workpiece to be cut 30 according to the mark offset parameter.

[0065] In the embodiment, the preset identification interval is adjusted according to the identification offset parameter, the position of the cutting identification to be calibrated is determined again according to the adjusted preset identification interval, so as to ensure the cutting accuracy, and then ensure the product quality obtained after cutting the workpiece to be cut 30.

[0066] In the application, the identification offset parameter is calculated according to the identification region length, the preset cutting times and the preset identification interval, so as to calibrate the position of the cutting identification to be calibrated according to the identification offset parameter. In this way, on the basis of the identification region length, the position of each cutting identification to be calibrated is re-adjusted according to the identification offset parameter, so as to ensure the product quality obtained by cutting in the cutting region determined according to each cutting identification, and the cutting accuracy is high.

[0067] In some optional implementations, before the step of obtaining the identification region length of the workpiece to be cut and the preset cutting data in the step S201, the method further includes:

[0068] obtaining a preset alignment rule and a cutting identification of a starting point in the workpiece to be cut 30;

[0069] extracting a reference mark and an alignment condition from the preset alignment rule, and adjusting the position of the workpiece to be cut 30, so that the positional relationship between the cutting identification of the starting point and the reference mark meets the alignment condition.

[0070] In the embodiment, any one of the cutting identifications in the workpiece to be cut 30 can be selected as the cutting identification of the starting point. Generally, the cutting identification of the starting point is the first cutting identification among all the cutting identifications. If the selected cutting identification of the starting point is located between the first cutting identification and the last cutting identification among all the cutting identifications, in the subsequent process, the identification region length is calculated according to the sum of the distance between the cutting identification of the starting point and the first cutting identification and the distance between the cutting identification of the starting point and the last cutting identification.

[0071] For example, continuing to refer to Figure 3 The above cutting identification is an identification point 31, and in Figure 3 The identification point 31 of the starting point in the above is the leftmost (first) identification point 31

[0072] In this step, the above reference mark can be arranged outside the workpiece to be cut 30, and the above alignment condition can be that the cutting identification is parallel to the reference mark.

[0073] For example, in a multi-axis cutting device, the multi-axis cutting device comprises an X-axis assembly, a T-axis assembly (a rotating shaft assembly), and a material loading platform, wherein the X-axis assembly and the T-axis assembly are in driving connection with the material loading platform, and the material loading platform is used for loading the to-be-cut part 30; in actual application, the X-axis of the X-axis assembly can be taken as a reference mark, the material loading platform is driven to rotate by the T-axis assembly in the four-axis cutting device, the position of the cutting mark on the to-be-cut part 30 is adjusted, the cutting mark is parallel to the X-axis, and thus the alignment of the position of the to-be-cut part 30 is completed; in addition, the multi-axis cutting device can also comprise a Y-axis assembly and / or a Z-axis assembly, and the Y-axis of the Y-axis assembly or the Z-axis of the Z-axis assembly can be taken as a reference mark, and the alignment of the position of the to-be-cut part 30 can also be achieved.

[0074] In addition, the alignment condition can also be that the cutting mark is perpendicular to the reference mark or forms a preset angle, and the principle of “perpendicular or forming a preset angle” is the same as that when “the alignment condition can be that the cutting mark is parallel to the reference mark” in the above embodiment, and will not be described further herein.

[0075] In some optional implementations, after the step of adjusting the position of the to-be-cut part 30 so that the position relationship between the cutting mark at the starting point and the reference mark satisfies the alignment condition, the method further comprises:

[0076] obtaining the cutting mark at the starting point in the calibrated to-be-cut part 30, and calculating an included angle parameter between the cutting mark at the starting point and the reference mark;

[0077] extracting a preset angle threshold from the preset alignment rule, and determining whether the included angle parameter satisfies the preset angle threshold;

[0078] if the included angle parameter satisfies the preset angle threshold, the position alignment of the cutting mark at the starting point is successful;

[0079] if the included angle parameter does not satisfy the preset angle threshold, the position alignment of the cutting mark at the starting point fails, the position of the to-be-cut part 30 is re-adjusted, the included angle parameter between the cutting mark at the starting point and the reference mark after re-calibration is calculated, and the process is repeated until the included angle parameter between the cutting mark at the starting point and the reference mark after re-calibration satisfies the preset angle threshold.

[0080] In the embodiment, after the position of the cutting mark of the starting point is calibrated, the position accuracy of the cutting mark of the starting point can be insufficient due to device vibration and rotation accuracy; therefore, the calibrated position of the cutting mark needs to be verified. Specifically, image information of the reference mark and the cutting mark of the starting point is collected according to the image collection mode, and after the image information is identified, the angle parameter between the cutting mark and the reference mark can be determined according to the angle between the cutting mark and the reference mark and the horizontal line, or the angle parameter between the cutting mark and the reference mark can be calculated by identifying the coordinates of the cutting mark and the reference mark. After the angle parameter is obtained, the angle parameter is compared with the preset angle threshold value. If they are the same, it is determined that the position of the cutting mark of the starting point is successfully aligned. If they are not the same, it is determined that the position of the cutting mark of the starting point fails to be aligned, and the cutting mark of the starting point needs to be calibrated and verified again.

[0081] It should be noted that if the alignment condition is that the cutting mark of the starting point is parallel to the reference mark, and the preset angle threshold value is 0 degrees; if the alignment condition is that the cutting mark of the starting point is perpendicular to the reference mark, and the preset angle threshold value is 90 degrees; if the alignment condition is that the cutting mark of the starting point is at a preset angle with the reference mark, and the preset angle threshold value is the preset angle.

[0082] In some optional implementations, in step S201, the step of obtaining the length of the identification region of the to-be-cut part 30 includes:

[0083] obtaining a first position parameter of the cutting mark of the starting point and a second position parameter of the cutting mark of the ending point in the to-be-cut part 30 after calibration;

[0084] calculating the length of the identification region according to the first position parameter and the second position parameter.

[0085] In the embodiment, the first position parameter and the second position parameter are both coordinate parameters.

[0086] Specifically, the image information of the to-be-cut part 30 is collected first, and the coordinate parameters of the cutting mark of the starting point and the coordinate parameters of the cutting mark of the ending point are identified from the image information. Then, the length of the identification region is calculated according to the two-point distance calculation formula. For example, the coordinate parameters of the cutting mark of the starting point are (0, 0), and the coordinate parameters of the cutting mark of the ending point are (0, 12). According to the two-point distance calculation formula The length of the identification region is calculated to be 12.

[0087] In some optional implementations, in step S202, the step of calibrating the position of the to-be-calibrated cutting mark of the to-be-cut part 30 according to the identification offset parameter includes:

[0088] acquiring a current cutting number, determining a cutting mark to be calibrated in the workpiece according to the current cutting number;

[0089] calculating a third position parameter of the cutting mark to be calibrated according to the current cutting number, the first position parameter, the preset mark interval and the mark offset parameter;

[0090] calibrating the position of the cutting mark to be calibrated according to the third position parameter.

[0091] In the embodiment, the first position parameter is a coordinate parameter, the current cutting number is N, where N≥2 and N is an integer; when each cutting mark is arranged along the X direction, the X coordinate parameter corresponding to each cutting mark is the same, the Y coordinate parameter is different, the product of the current cutting number and the mark offset parameter is calculated first to obtain a product value, then the Y coordinate parameter in the first position parameter, the preset mark interval and the product value are added to obtain the Y coordinate parameter of the third position parameter of the cutting mark to be calibrated, and since the X coordinate parameter corresponding to each cutting mark is the same, the third position parameter of the cutting mark to be calibrated is obtained.

[0092] It should be noted that each cutting mark can also be arranged along the Y direction or the Z direction, and the principle of calculating the third position parameter in the "Y direction or Z direction" is the same as that of the "cutting mark arranged along the X direction" described above, which will not be described in detail here.

[0093] In some optional implementations, in step S202, the step of calculating the mark offset parameter according to the mark region length, the preset cutting number and the preset mark interval comprises:

[0094] calculating an actual mark interval according to the mark region length and the preset cutting number, where the actual mark interval represents the interval between two adjacent cutting marks in the workpiece 30;

[0095] calculating the mark offset parameter according to the actual mark interval and the preset mark interval.

[0096] In the embodiment, the mark region length is divided by the preset cutting number to obtain the actual mark interval, and then the mark offset parameter is calculated by calculating the difference between the actual mark interval and the preset mark interval; in this way, whether the position of the cutting mark on the workpiece 30 is the same as the preset position of the cutting mark can be determined according to the mark offset parameter, and the cutting accuracy is effectively ensured.

[0097] In some optional implementations, in step S203, before the step of calibrating the position of the cutting mark to be calibrated in the workpiece 30 according to the mark offset parameter, the method further comprises:

[0098] obtaining a preset offset threshold, and determining whether the identification offset parameter meets the preset offset threshold;

[0099] If the identification offset parameter meets the preset offset threshold, outputting the identification offset parameter;

[0100] If the identification offset parameter does not meet the preset offset threshold, obtaining a preset determination rule and a historical identification offset parameter, determining an identification offset parameter meeting the preset offset threshold from the historical identification offset parameter according to the preset determination rule, and outputting the identification offset parameter meeting the preset offset threshold.

[0101] In the embodiment, after obtaining the identification offset parameter, the identification offset parameter needs to be verified to ensure the accuracy of the position of the cutting mark adjusted according to the identification offset parameter, so that the product size cut from the workpiece 30 is controlled within the preset error range.

[0102] In this step, the above-mentioned preset offset threshold is pre-stored in a database and can be obtained by calling the pre-stored database. In addition, after each identification offset parameter passes the verification, the identification offset parameter that passes the verification is stored in the database or uploaded to the cloud. The above-mentioned preset determination rule is to average the historical identification offset parameters, and the average processed identification offset parameter is used as the identification offset parameter meeting the preset offset threshold. In this way, the product cut by the cutting mark determined according to the identification offset parameter has good consistency with the historical product specifications. In addition, the historical identification offset parameters can also be classified according to the offset range, such as class 1 for identification offset parameters 0 to 0.3, class 2 for identification offset parameters 0.3 to 0.5, and so on. At this time, the above-mentioned preset determination rule is to obtain the class containing the largest number of identification offset parameters from the historical identification offset parameters, and randomly select an identification offset parameter from the class containing the largest number of identification offset parameters as the identification offset parameter meeting the preset offset threshold. In this way, the product quality cut by the cutting mark determined according to the identification offset parameter can be effectively guaranteed.

The computer program can be stored in a computer readable storage medium. When the program is executed, it can include the processes of the above-mentioned embodiments. The storage medium can be a non-volatile storage medium such as a magnetic disc, an optical disc, a read-only memory (ROM), or a random access memory (RAM).
