[0044] Figure 1 It is a flowchart of a method executed in a processor in a laser nesting system for automatic nesting in an embodiment of the present application. DETAILED DESCRIPTION

[0045] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed. However, as long as it is within the scope of the claims of the present application, it shall be protected by the patent law.

[0046] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0048] The present application provides a laser nesting system for automatic nesting, wherein the laser nesting system comprises a processor, and the following method is executed in the processor. The main process of the method is described as follows.

[0049] like Figure 1 As shown, the method executed in the processor includes obtaining plate waste information and parts information; performing matching analysis based on the plate waste information and parts information to determine the plate group; calculating the cutting process and cutting path of each plate group to obtain cutting parameter information; comparing the cutting parameter information of each plate group to determine parameter adjustment information, and obtaining the plate processing sequence based on the parameter adjustment information.

[0050] Among them, in the embodiment of the present application, obtaining the plate residual information specifically includes: obtaining the preset nesting processing task information and the preset plate information; obtaining the plate residual information according to the preset nesting processing task information and the preset plate information; it can be understood that the plate residual mentioned in the embodiment of the present application refers to the total amount of material remaining after processing the plate; the preset nesting processing task information refers to the pre-set processing task to be performed on the plate; and the preset plate information refers to the pre-prepared plate information, then according to the established plate processing task and plate information, it can be determined that after completing the processing of the plate, the remaining material information of the plate, that is, the plate residual information; it should be noted that, in addition to the above-mentioned method, the other methods of obtaining the plate residual information are also included in the scheme of the present application, that is, all methods involving plate processing tasks and plate information, and obtaining the plate residual information according to these two information, are within the scope of protection of the present application.

[0051] In an embodiment of the present application, determining a plate group based on matching analysis of the plate scrap information and the part information specifically includes: determining the material information required for the part based on the part information; determining the cuttable part information corresponding to each plate scrap based on matching of the plate scrap information and the material information required for the part; and grouping the plate scraps with the same cuttable part information to obtain a plate group.

[0052] It can be understood that after obtaining the sheet material scrap information and part information, it is necessary to match and analyze the two to determine the sheet material group; first determine the material information required for the part based on the part information, that is, the material type, size, thickness and other information required for part processing; then match the sheet material scrap with the material required for the part to determine the cuttable parts that can be completed by the sheet material scrap; finally, divide the sheet material scraps that can cut the same parts into the same group to obtain a sheet material group; through the above method, the remaining sheet material scraps can be analyzed to determine what parts can be made from these sheet material scraps; then determine the sheet material scraps that can make the same parts, and group these sheet material scraps so that the sheet material scraps that can make the same parts can be processed uniformly; in this way, the sheet material scraps are grouped, which facilitates the unified processing of the sheet material scraps and improves the processing efficiency of the sheet material scraps.

[0053] Specifically, in the above process, matching the sheet material residue information and the material information required for the parts to determine the cuttable part information corresponding to each sheet material residue specifically includes: determining the operable parts according to the sheet material residue information and the material information required for the parts; determining the total material ratio value according to the sheet material residue information and the operable parts; selecting the operable part with the largest total material ratio value, and marking the operable part as the cuttable part of the corresponding sheet material residue.

[0054] Wherein, determining the operable part according to the sheet material surplus information and the part material information specifically includes: determining the total value of the part material and the part shape information according to the part material information required; determining the total value of the sheet material surplus and the sheet material surplus shape information according to the sheet material surplus information; determining the first judgment information according to the total value of the sheet material surplus and the total value of the part material; determining the second judgment information according to the sheet material surplus shape information and the part shape information; determining the operable part according to the first judgment information and the second judgment information. Wherein, determining the first judgment information according to the total value of the sheet material surplus and the total value of the part material specifically includes: comparing the total value of the sheet material surplus and the total value of the part material; if the total value of the sheet material surplus is greater than the total value of the part material, the first judgment information is yes; otherwise, the first judgment information is no. Wherein, determining the operable part according to the first judgment information and the second judgment information specifically includes, when the first judgment information is yes and the second judgment information is yes, the part is an operable part.

[0055] It can be understood that in the above process, when matching and analyzing the plate residue and the parts, the parts that can be operated are first determined based on the plate residue information and the materials required for the parts; that is, the plate residue can support the parts for processing; the analysis is performed from two perspectives, the first perspective is from the total value of the part material and the total value of the plate residue, where the total value is a parameter used to reflect the material content of the parts and the plate, and the first judgment information can be determined by the total value of the plate residue and the total value of the part material, and the first judgment information reflects the judgment information that the part can be regarded as an operable part under the first perspective; the second perspective is to analyze from the shape of the part and the shape of the plate residue, and it is necessary to determine that the shape of the plate residue can meet the shape of the part, that is, the processing of the part, otherwise even if the content of the plate residue is higher than the material required for the part, the processing of the part cannot be realized; the second judgment information can be determined by the plate residue shape information and the part shape information; the second judgment information reflects the judgment information that the part can be regarded as an operable part under the second perspective; based on the above first judgment information and second judgment information, the part will be regarded as an operable part only when the first judgment information and the second judgment are both yes.

[0056] In the above judgment process, the first judgment information is obtained by comparing the total value of the plate residue and the part material. By comparing the size of the value, the judgment result can be obtained more intuitively; that is, if the total value of the plate residue is greater than the total value of the part material, the first judgment information is yes; otherwise, if the total value of the plate residue is not greater than the total value of the part material, the first judgment information is no.

[0057] As for the second judgment information, it is based on shape comparison. It can adopt an image method, by obtaining images of sheet material residues and parts, overlaying and comparing the two images, and then judging the relationship between the two; if the sheet material residue image can cover the part image, the second judgment information is yes, otherwise, the sheet material residue image cannot cover the part image, and the second judgment information is no; through the above method, the first judgment information and the second judgment information are both displayed with two results of yes and no, which facilitates subsequent judgment, simplifies the judgment of whether a part is an operable part, improves the judgment efficiency of parts, and thus improves the processing efficiency of the overall process.

[0058] In an embodiment of the present application, calculating the cutting process and cutting path of each plate group to obtain cutting parameter information specifically includes: determining the part processing process information based on the part information; determining the cutting process and cutting path based on the plate waste information and part processing process information of the plate waste in the plate group; determining the cutting parameter information based on the cutting process and cutting path.

[0059] It can be understood that when calculating the cutting parameter information of the plate group, the cutting process and cutting path of each plate in the plate group are calculated; specifically, in the above process, the part information that can be processed for each plate in the plate group is determined; then the part processing process information can be determined based on the part information; and then the cutting process and cutting path can be determined based on the plate waste information of the plate waste in the plate group; after obtaining the cutting process and cutting path, the cutting parameter information can be determined based on the cutting process and cutting path.

[0060] It is understandable that the process of determining cutting parameter information according to the cutting process is a conventional technology; however, in the present application, the cutting parameters are determined not only according to the cutting process but also according to the cutting path; that is, the cutting parameters include the cutting path information.

[0061] After obtaining the cutting parameter information, the parameter adjustment information is determined by comparing the cutting parameter information of each plate group; then the plate processing order is determined according to the parameter adjustment information; it can be understood that after obtaining the cutting parameter information, the cutting parameter information between any two plate groups is compared, and after comparing the cutting parameter information of any two plate groups, it can be determined that the cutting parameters need to be adjusted from one plate group to another, that is, the parameter adjustment information; the parameter adjustment information can be used to determine the degree of parameter adjustment between the plate groups. In order to ensure the processing efficiency of the overall project, the plate groups with a smaller degree of parameter adjustment are selected as adjacent plate groups, and then the plate processing order is obtained through the parameter adjustment information.

[0062] It can be understood that, through the above scheme, the matching analysis of the plate waste information and the parts information is realized, and the cutting parameters are obtained by determining the plate group and analyzing the cutting process and path of the plate group; then, the final plate processing sequence is determined by comparing and analyzing the overall cutting parameters of each plate group; in this way, the automatic nesting of the laser nesting system is realized; for the plates that need to be nested, the plate waste is automatically processed using the pre-calculated plate processing sequence, which improves the utilization efficiency of the plate and the processing efficiency of the plate.

[0063] In an embodiment of the present application, the plate groups are divided by the same parts that can be processed by the plate waste. When selecting the processing parts, the parts with the largest proportion of the total material amount are regarded as operable parts, and then the plate waste that can process the same parts are divided into one group to obtain plate groups. In this way, it can be ensured that the plate waste in each plate group can be maximized. However, there is a problem with this method. There may be too many divided plate groups, resulting in that when the plate groups are processed, when the processing parameters are adjusted between the plate groups, more parameters need to be adjusted, which is more frequent and cumbersome. Therefore, when selecting the processing parts, it is necessary to balance the processing efficiency of the plate group and the utilization efficiency of the plate waste.

[0064] Specifically, information on cuttable parts corresponding to the plate waste is obtained; a plurality of ordered plate processing groups are obtained according to the information on cuttable parts and preset division and sorting rules; the ordered plate processing groups contain a plurality of groups of plates to be processed arranged in a predetermined order; the groups of plates to be processed contain a plurality of plate wastes containing the same machinable parts; the proportion values ​​of part materials of each ordered plate processing group are calculated; the proportion values ​​of part materials are the plate utilization rates of the ordered plate processing groups; processing parameter adjustment information between the groups of plates to be processed in each ordered plate processing group is calculated; the plate processing efficiency of each ordered plate processing group is determined according to the processing parameter adjustment information; first selection information is obtained according to the plate utilization rate and the plate processing efficiency; the plate selection ratio of each ordered plate processing group is obtained by dividing the plate processing efficiency by the plate utilization rate; second selection information is obtained according to the plate selection ratio and preset plate selection rules; the final ordered plate processing group is determined according to the first selection information and the second selection information.

[0065] In the above process, the part information that can be cut from the sheet metal scraps is first obtained, and then the sheet metal scraps are divided into multiple sheet metal processing groups according to the preset division and sorting rules and the part information, and sorted based on the preset division and sorting rules, and finally multiple ordered sheet metal processing groups are obtained.

[0066] The preset division and sorting rules here include marking each part that can be cut from the plate waste as a processing part of the plate waste, and dividing the plates with the same marked processing parts into plate groups through exhaustive method, calculating the adjustment parameters between the plate groups, and sorting the plate groups in ascending order according to the adjustment parameters, thereby obtaining multiple ordered plate processing groups; for example, plate waste A, B, C; parts 1, 2, 3; wherein plate waste A and B can process parts 1 and 2, and plate waste C can process parts 2 and 3; according to the preset division and sorting rules, the plate waste is grouped to obtain plate groups, and then the plate groups are combined to obtain plate processing groups; the first plate processing group is plate group AB (processing part 1), plate group C (processing part 2); the second plate processing group is plate group ABC (processing part 2); the third plate processing group is , plate group AB (processing part 1), plate group C (processing part 3); the fourth plate processing group is plate group AB (processing part 2), plate group C (processing part 3); the fifth plate processing group is plate group A (processing part 1), plate group BC (processing part 2); the sixth plate processing group is plate group A (processing part 1), plate group B (processing part 2), plate group C (processing part 3); the seventh plate processing group is plate group AC (processing part 2), plate group B (processing part 1); the eighth plate processing group is plate group A (processing part 2), plate group B (processing part 1), plate group C (processing part 3); after obtaining the above-mentioned plate processing groups, the parameter adjustment information between the plate groups to be processed in the plate processing group is analyzed and calculated, and finally a plurality of ordered plate processing groups are obtained.

[0067] After obtaining multiple ordered plate processing groups, the parts material ratio values ​​in the ordered plate processing groups are calculated; the parts material ratio values ​​are calculated by calculating the material ratios of the parts that need to be processed in each plate residue in each plate group to be processed in the ordered plate processing group, and obtaining the material ratio values ​​corresponding to each plate residue; then the material ratio values ​​corresponding to the plate residues are added up and divided by the number of plate residues to obtain the material ratio values ​​of each plate group to be processed; then the material ratio values ​​of each plate group to be processed are added up and divided by the number of plate groups to be processed to obtain the parts material ratio values ​​of each ordered plate processing group; the parts material ratio values ​​calculated in the above manner can effectively reflect the plate utilization rate of the ordered plate processing group.

[0068] Among the multiple groups of plates to be processed included in the ordered plate processing group, the parts to be processed by each group of plates to be processed are the same. Therefore, when calculating the processing parameter adjustment information between the groups of plates to be processed in each ordered plate processing group, it is only necessary to calculate the processing parameter adjustment information between the parts to be processed corresponding to each group of plates to be processed; after obtaining the processing parameter adjustment information, the plate processing efficiency of each ordered plate processing group can be determined according to the processing parameter adjustment information; the calculation method of the plate processing efficiency here can be based on the complexity of the processing parameter adjustment and the time consumed for the adjustment; that is, the adjustment complexity is determined according to the processing parameter adjustment information, and the adjustment complexity here can be reflected by a specific value; and the time consumed for the adjustment can also be obtained through the processing parameter adjustment information; and then based on the preset weight, the plate processing efficiency is calculated in combination with the adjustment complexity and the time consumed for the adjustment.

[0069] After obtaining the plate utilization rate and the plate processing efficiency, the final ordered plate processing group can be determined based on the two; it can be understood that when the first selection information is obtained based on the plate utilization rate and the plate processing efficiency, the first selection score of each ordered plate processing group can be obtained by performing corresponding calculations based on the preset weights and combining the plate utilization rate and the plate processing efficiency; by comparing the first selection scores of each ordered plate processing group, a suitable ordered plate processing group is selected as the first selection information.

[0070] It should be noted that in the above process, it is necessary to first screen the plate utilization rate and the plate processing efficiency, and screen out the ordered plate processing groups corresponding to the lower plate utilization rate and plate processing efficiency; the specific method is to preset the minimum plate utilization rate threshold and the minimum plate processing efficiency threshold, compare the plate utilization rate of each ordered plate processing group with the preset minimum plate utilization rate threshold, and compare the plate processing efficiency with the preset minimum plate processing efficiency threshold; screen out the ordered plate processing groups corresponding to the two cases where the plate utilization rate is less than the preset minimum plate utilization rate threshold, or the plate processing efficiency is less than the preset minimum plate processing efficiency threshold; then the remaining ordered plate processing groups are calculated according to the above-mentioned preset weights, combined with the plate utilization rate and the plate processing efficiency, to obtain the first selection score of each ordered plate processing group, and then determine the first selection information according to the first selection score.

[0071] When determining the first selection information based on the first selection score, the first selection scores of each ordered plate processing group are compared. Then, it is possible that the first selection scores of any number of ordered plate processing groups far exceed those of the remaining ordered plate processing groups, and the first selection scores of each other are relatively close, that is, the first selection scores of any number of ordered plate processing groups are greater than the preset score threshold, and the difference in the first selection scores between any number of ordered plate processing groups is less than the preset difference. At this time, the above-mentioned arbitrary number of ordered plate processing groups constitute the first selection information, and the second selection information is needed to assist in the selection.

[0072] Specifically, the plate selection ratio obtained by dividing the plate processing efficiency by the plate utilization rate can reflect the plate processing efficiency corresponding to each unit plate utilization rate; calculate the plate selection ratio corresponding to each ordered plate processing group; wherein the preset plate selection rule includes sorting the ordered plate processing groups from large to small according to the plate selection ratio, and selecting a preset number of ordered plate processing groups starting from the first place as the second selection information.

[0073] Finally, the intersection of the first selection information and the second selection information is obtained, and the ordered plate processing group contained in the intersection is regarded as the final ordered plate processing group; it can be understood that in the second selection information, the preset number can be adaptively adjusted, such as 1-3, after the final ordered plate processing group is obtained, the remaining ordered plate processing groups in the intersection are regarded as spare ordered plate processing groups to prevent the final ordered plate processing group from being unable to be executed when a special situation occurs, and the spare ordered plate processing group is selected for processing.

[0074] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of disclosure involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the aforementioned disclosed concept. For example, the above features are replaced with the technical features with similar functions disclosed in this application (but not limited to) by each other to form a technical solution.
