[0068] Embodiments of the present invention provide a riveting process assessment determination method, device, electronic device, and computer-readable storage medium, which can improve the generation and management efficiency of riveting process assessments during use.

[0069] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0070] It should be noted that the riveting process, as a special process, requires process management encompassing people, machines, materials, methods, and the environment. This process management encompasses roles and responsibilities within the process, risk management, process assessment, process validation, process control and monitoring (indicators), nonconformity management, change management, transfer management, supply chain management, special process audits / inspections, knowledge management, and special processes performed by external suppliers. Riveter assessment is an important basis for developing riveting procedures and a crucial step in pre-production process validation. The riveting process assessment report generated through this process verifies the accuracy and applicability of the riveting process. At present, there are no systematic and universal standard requirements for riveting process assessment, and the important variables of the process are not unified. The riveting process involves variable factors such as material combination, rivet type, hole making method, bonding requirements, anti-corrosion requirements, riveting method, riveting mode, etc. that affect quality; changes in each variable factor will have a significant impact on the riveting process formulation, and need to be identified and confirmed, so as to formulate a set of riveting process assessment coverage methods based on changes in riveting process variable factors. The riveting process assessment involves many factors. After the assessment project is completed, there is currently no effective method for rapid identification of assessment projects, which is not conducive to process assessment identification and management of multi-type, multi-specification, and large-scale riveting.

[0071] In view of this, the present application provides a riveting process evaluation determination method that can improve the generation and management efficiency of riveting process evaluation. Figure 1 , Figure 1 A flow chart of a method for determining a riveting process evaluation provided by an embodiment of the present invention. The method for determining a riveting process evaluation includes:

[0072] S110: Obtaining all element information of the riveted structure to be evaluated;

[0073] It should be noted that in actual applications, all element information of the riveted structure to be evaluated can be obtained, such as the base material (i.e., connected material) element, adhesive element, hole making element, rivet collar element, riveted joint element, and riveting process element. Among them, the base material element includes five elements: material category, thickness, coating, prefabricated hole diameter, and surface treatment; the adhesive element includes four elements: adhesive model, coating position, operable time, and curing time; the hole making element includes five elements: hole diameter, hole making method, hole making type, countersink diameter, and countersink method; the rivet collar element includes six elements: rivet type, rivet model, rivet diameter, clamping thickness, rivet material, and collar model; the riveted joint element includes two aspects: joint design and joint preparation. Among them, the joint design includes the joint code and joint summary. Figure 2Elements, joint preparation includes two elements: schematic diagram and gap; riveting process elements include three aspects: riveting method, riveting gun information and riveting position. Among them, riveting method includes four elements: installation method, riveting type, riveting classification and riveting mode; riveting gun information includes four elements: riveting gun name, riveting gun model, gun head model and power mode; riveting position includes one element: position name. S120: Based on each process assessment item, extract the key element information corresponding to each process assessment item from all element information;

[0074] It is understandable that each process assessment item can be predetermined based on various factors that most significantly affect the riveting process assessment, and then key element information corresponding to each process assessment item can be extracted from all element information.

[0075] S130: According to each key element and a pre-established coverage rule corresponding to each key element, a target riveting process assessment covering each key element is determined from a pre-established riveting process assessment database;

[0076] Specifically, after obtaining the key element information of the riveted structure to be evaluated, the riveting process evaluation can be performed based on the key element information. In order to improve the determination efficiency of the riveting process evaluation, a target riveting process evaluation that can meet the coverage rules can be determined from the existing riveting process evaluations stored in the riveting process evaluation database based on the key elements of the structure to be evaluated and the pre-established coverage rules corresponding to each key element.

[0077] S140: Using the target riveting process assessment as the riveting process assessment of the riveted structure to be assessed.

[0078] That is, after determining the target process assessment, the target process assessment is output as the riveting process assessment of the riveted structure to be assessed, thereby quickly, accurately and efficiently determining the riveting process assessment of the riveted structure to be assessed.

[0079] It can be seen that in this application, all element information of the riveted structure to be evaluated can be obtained, and then the corresponding key element information can be determined from all the element information according to the pre-set evaluation items, and then the target riveting process evaluation that meets the corresponding coverage rules can be determined from the pre-established riveting process evaluation database according to the key element information, so as to obtain the riveting process evaluation of the riveted structure to be evaluated. In this application, the generation and management efficiency of the riveting process evaluation can be improved.

[0080] In one embodiment, in this embodiment, based on the characteristics of the riveting process elements, focusing on the special process aspects of people, machines, materials, methods, environment, and measurement, the process evaluation items are pre-determined to include at least two of the manufacturer, riveted joint, connected material, rivet and collar, hole making, adhesive, anti-corrosion and general riveting process rules; in actual application, all process evaluation items can be included, as shown in Table 1.

[0081] The key element information determined around the above process assessment items may include: manufacturer information, joint type, material type, material thickness, rivet model, ring model, hole making type, hole making method, adhesive type, paint type, riveting method, riveting gap, riveting classification, degree of automation and riveting method.

[0082] Specifically, please refer to Table 1, which includes various evaluation items, key factor variables corresponding to each evaluation item, and remark information, wherein the remark information is the evaluation content information, that is, what aspects of the evaluation need to be performed when conducting process evaluation for the evaluation item.

[0083] Accordingly, the process of extracting key element information corresponding to each process assessment item from each element information based on each process assessment item may include:

[0084] From the information of each element, determine the joint type corresponding to the riveted joint, the material type and material thickness corresponding to the connected material, the rivet model and ring model corresponding to the rivet and ring, the hole making type and hole making method corresponding to the hole making, the adhesive type corresponding to the adhesive, the paint type corresponding to the anti-corrosion, the riveting method, riveting gap, riveting classification, degree of automation and riveting method corresponding to the general rules of the riveting process. Detailed key element information can be found in Parameter Table 1.

[0085] Table 1 Riveting process assessment factors In one embodiment, it should be noted that, in order to improve the accuracy of the riveting process assessment, corresponding coverage rules can be determined in advance for each key element information. Figure 2 , as follows:

[0086] The coverage rule corresponding to the manufacturer information is that the manufacturer information is the same as the manufacturer information in the existing riveting process assessment.

[0087] It should be noted that manufacturer information can only be overwritten if the manufacturer information of the existing riveting process qualification in the riveting process qualification database is the same as the manufacturer information of the riveted structure to be qualified. In other words, the existing riveting process qualification is valid only if the manufacturer information of the same technical and quality control workshop or site as the manufacturer of the riveted structure to be qualified is the same.

[0088] In other words, the existing riveting assessment results can only cover the product manufacturers that implemented the riveting process assessment. The manufacturer's name will be reflected in the process assessment report. That is, the riveting process assessment results implemented by manufacturer A cannot be used for manufacturer B. Manufacturer B needs to conduct assessment experiments based on its own conditions and formulate corresponding riveting process assessments.

[0089] The coverage rule corresponding to the joint type is that the joint type is the same as the joint type in the existing riveting process assessment;

[0090] That is, only when the joint types are the same, the existing riveting process assessment can meet the coverage rules corresponding to the joint type. In practical applications, in order to facilitate comparison, the riveted joints can be classified in this embodiment and classification rules can be formulated, such as Figure 3 For the various types of rivets shown, if the riveted joint of a certain existing riveting process assessment (indicated by P1) is R11-2 (two-layer connection of blind rivets), then the riveting process assessment can only support the riveting process of the R11-2 riveted joint; if the riveted joint corresponding to the riveting process (P1) to be formulated is a three-layer plate connection (R11-3), then the existing riveting process assessment cannot support the riveted joint, and it is necessary to conduct an assessment and verification of the riveted joint R11-3 (or match the process assessment items of the R11-3 joint). For example, if the riveting process (P1) joint to be formulated is R21-2 (two-layer connection of ring groove rivets), it is necessary to conduct an assessment and verification of R21-2 (or match the process assessment items of the R21-2 joint). Among them, the joint code naming method of the riveted joint should be based on Figure 4 The rivet joint code can be expressed as R**-*, where "*" is represented by a number, R represents the rivet type, the first "*" to the right of R represents the rivet code (represented by the numbers 1, 2...), the second "*" to the right of R represents the rivet sub-code (represented by the numbers 1, 2...), and the last "*" represents the number of connected layers (represented by the numbers 1, 2...).

[0091] The coverage rule corresponding to the material type is that the material type is the same as the material type in the existing riveting process assessment;

[0092] That is, only materials of the same type can cover each other. For example, the embodiment of the present invention can classify the materials to be connected, and the material types are mainly divided into aluminum alloy (A), stainless steel (S), carbon steel (C), titanium alloy (Ti), composite material (F), etc. Figure 3As shown in the figure, if the material 1 of a riveting process assessment (represented by P1) is Q235 (C) and t2 is CFRP (F), the material type combination is expressed as C / F. If the riveting process to be developed is Q345 (C) and t2 is CFRP (F), and the type combination is also expressed as C / F, then this process assessment (P1) can support the riveting process of the riveted structure to be assessed, and no further assessment verification is required. If the riveting process to be developed is A5356 (A) and t2 is CFRP (F), and the type combination is also expressed as A / F, this assessment (P1) cannot support the riveting process, and assessment verification of the A / F material combination (or a process assessment item matching the A / F material combination) is required.

[0093] The covering rule corresponding to the material thickness is that the material type is the same as the material type in the existing riveting process qualification;

[0094] It can be understood that, with respect to material thickness, as long as the material types are the same and the material types and combinations are the same, only one thickness needs to be assessed, and the other thicknesses can be covered by the assessed thickness.

[0095] It should also be noted that the thickness of the material being joined must match the clamping thickness of the rivet. For the same material type and combination, assessing one material thickness is sufficient, while other thicknesses do not need to be assessed. This is because, when using the same rivet model, clamping thickness is a non-significant variable. For example, in assessment item (P1), if the material combination of t1 and t2 is C / F and the thicknesses are 4+2, then the thicknesses of t1 and t2 for the same material combination do not need to be assessed.

[0096] The coverage rule corresponding to the rivet model is that the rivet model and rivet diameter are the same as the rivet model and rivet diameter in the existing riveting process assessment respectively;

[0097] Specifically, the riveting process assessments for rivets of the same model and diameter can overlap with each other, with the exception of clamping thickness. Since the selection of rivet model in the riveting process has a significant impact on the riveted structure, once a rivet model is selected, the corresponding clamping thickness has little impact.

[0098] like Figure 3For the R11-2 joint with medium assessment (P1), the rivet used is CR7620-08-04, where "CR7620" is a countersunk rivet of a certain brand (CR7621 is a raised head rivet), "-08" is the rivet diameter code (representing a diameter of 6.58±0.025), and -04 is the rivet clamping code (representing the rivet connection thickness range of 5.56-7.76), expressed as CR7620-08. If the riveting process to be developed uses CR7620-08-06 for rivets and the type combination is also CR7620-08, then this assessment (P1) can support the riveting process and no further assessment verification is required; if the riveting process to be developed uses CR7621-08-06 for rivets and the type combination is CR7621-08, then this assessment (P1) cannot support the riveting process and further assessment verification is required (or matching the process assessment item with the rivet type CR7621-08).

[0099] Another example Figure 3 For the R21-2 joint in the assessment (P2), the rivet used is C6LB-U12-22, and the collar is 3LC-U12. “C6LB” is a brand of break-off ring groove rivets, “-U12” is the rivet diameter code (representing a diameter of 9.65-9.78), and “-22” is the rivet clamping code (representing a rivet clamping thickness range of 31.75-38.10), expressed as C6LB-U12. If the riveting process to be developed uses C6LB-U12-18 rivets and the type combination is also expressed as C6LB-U12, then this assessment (P2) can support this riveting process and no further assessment verification is required; if the riveting process to be developed uses C6LB-U8-13 rivets and the type combination is expressed as C6LB-U8, then this assessment (P2) cannot support this riveting process and further assessment verification is required (or matching the process assessment item for the rivet type C6LB-U8).

[0100] The covering rule corresponding to the ferrule model is that the ferrule model is the same as the ferrule model in the existing riveting process assessment;

[0101] It should be noted that the same type of collars can overlap each other. Among them, the selection of collars in the riveting process has a significant impact on the riveted structure (only ring groove rivets have collars). Once a collar type is selected, it can only overlap collars of the same type, which is expressed as "rivet type (ring type)". Figure 3For the R21-2 joint of the assessment (P2), the rivet is C6LB-U12-22, and the rivet ring is 3LC-U12. "3LC" indicates the ring type, and "-U12" indicates the ring specification, which is marked as C6LB-U12 (3LC-U12). If the riveting process ring to be formulated is 3LC-U12, and the type combination is also expressed as C6LB-U12 (3LC-U12), then this assessment (P2) can support the riveting process and no further assessment verification is required; if the riveting process ring to be formulated is expressed as (2LC-U12), then this assessment (P2) cannot support the riveting process and further assessment verification is required (or matching the process assessment item with the ring type of 2LC-U12).

[0102] The coverage rule corresponding to the hole making type is that the hole making type is the same as the hole making type in the existing riveting process assessment;

[0103] It is understandable that the same type of hole types can overlap each other. In the embodiment of the present invention, the hole types can be divided into through holes (code TK) and countersunk holes (code CK), wherein the countersunk holes are used to match the countersunk rivets; the hole type and the connected material are represented separately, such as Figure 3 For the R11-2 joint of assessment (P1), t1 is a countersunk hole and t2 is a through hole, which is expressed as t1:CK / t2:TK; Figure 1 For the R21-2 joint of the evaluation (P2), t1 / t2 are both through holes, expressed as t1 / t2: TK.

[0104] The coverage rule corresponding to the hole making method is that the hole making method is the same as the hole making method in the existing riveting process assessment;

[0105] Specifically, the same type of hole making methods in this application can cover each other. In this embodiment, the hole making methods can be divided into drilling holes (code P) and machining holes (code J). Among them, drilling holes are riveted holes that require manual drilling at the assembly site of the parts, which means that the quality of drilling depends on manual skills and the hole making accuracy is low. Machining holes are riveted holes prepared by mechanical processing equipment, which means that the quality of hole making is guaranteed by mechanical equipment and the hole making accuracy is high. Figure 3 For the R11-2 joint evaluated (P1), t1 is a machined hole and t2 is a drilled hole, expressed as t1:CK-J / t2:TK-P.

[0106] The covering rule corresponding to the adhesive type is that the adhesive type is the same as the adhesive type in the existing riveting process assessment;

[0107] It should be noted that, provided that design requirements are met, the assessment is only valid for the adhesive type used in riveting process tests. That is, when adhesive is added to rivet connections, it can be divided into two categories based on its function: "structural adhesives": these serve both to seal the connected parts and have a high load-bearing capacity, and are high-strength adhesives (such as EP6250 structural adhesive), denoted by A1; "non-structural adhesives": these primarily serve to seal the connected parts and have only a low load-bearing capacity, and are low-strength adhesives (such as floor caulking), denoted by A2. In other words, all structural adhesives (high-strength adhesives) and non-structural adhesives (low-strength adhesives) cannot overlap each other, but adhesives of the same type can overlap.

[0108] The covering rule corresponding to the paint type is that the paint type is the same as the paint type in the existing riveting process assessment;

[0109] It should be noted that the process qualification for joints with anti-corrosion coatings does not apply to joints without coatings, and vice versa. In other words, whether the surfaces of the joined materials are coated with anti-corrosion coatings significantly affects the performance of the riveted structure. If the surfaces of the joined materials are coated with anti-corrosion coatings (indicated by Cot), then no qualification is necessary.

[0110] like Figure 3 For the R11-2 joint in the assessment (P1), t1 is coated with a "two-component epoxy primer" and t2 is uncoated, which can be expressed as t1 (Cot). If the required riveting process requires t1 to be coated with a "one-component epoxy primer" and t2 to be uncoated, expressed as t1 (Cot) as before, then this assessment (P1) can support this riveting process and no further assessment verification is required. If the required riveting process requires that both t1 and t2 materials are unprimed, then the coating type does not need to be expressed, and this assessment (P1) cannot support this riveting process, requiring further assessment verification (or matching the uncoated riveting process assessment items).

[0111] The following is an introduction to the coverage rules of each key element in the general process rules. The general rules are expressed as follows: Figure 6 shown.

[0112] The coverage rule corresponding to the riveting method is that the riveting installation method is the same as the riveting installation method in the existing riveting process assessment;

[0113] Specifically, similar installation methods can overlap each other. The present invention can classify installation methods, and the same installation methods can overlap each other. Specifically as follows:

[0114] a) Single-side rivet placement (Dd): The single rivet is placed from one side of the connected parts, and the rivet gun contacts the rivet from one side during riveting;

[0115] b) Single-side rivet placement and double-side riveting (Ds): Single rivets are placed from one side of the connected parts, and the rivet gun is used to contact the rivet from both sides during riveting;

[0116] c) Double-sided rivet placement (Sd): Split rivets are placed from both sides of the connected parts, and the rivet gun contacts the rivet from one side during riveting;

[0117] d) Double-sided rivet placement (Ss): Split rivets are placed from both sides of the connected parts, and the rivet gun equipment contacts the rivets from both sides during riveting;

[0118] like Figure 3 For the R11-2 joint with medium assessment (P1), the rivets used are CR7620-08, the single rivet is placed from the side of the connected parts, the rivet gun is used to rivet the rivet on one side, and the riveting method code is (Dd); Figure 3 For the R21-2 joint with medium assessment (P2), the rivets used are C6LB-U12. The rivet group consists of separate rivets and rings. The rivets and rings are installed in the rivets from both sides of the connected parts respectively. The split rivets are placed from both sides of the connected parts. When riveting, the rivet gun is equipped with single-sided contact rivets. The riveting method code is (Sd).

[0119] The coverage rule corresponding to the riveting gap is that the riveting gap is within the riveting gap range in the existing riveting process assessment;

[0120] It should be noted that the coverage rule for the riveting gap is that the gap ranges within the assessment range can overlap each other. Since the riveting gap is an important parameter in the riveting process, for riveted joints without adhesives, the assembly gap of the connected parts needs to be controlled to 0, and for joints with adhesive filling, the gap needs to be controlled within a certain range. The specific control needs to be verified through the riveting process assessment, and the riveting gap can be directly expressed in numbers. Figure 3 For the medium-rated (P1) R11-2 joint, the maximum clearance is 0.3mm (expressed as 0.3), and the approved range is 0-0.3mm clearance. If the riveted clearance of the riveted structure to be assessed is within the 0-0.3mm clearance range, it can be covered.

[0121] The coverage rule corresponding to the riveting classification is that the type of riveting classification is the same as the type of riveting classification in the existing riveting process assessment;

[0122] The same type of riveting classification can overlap each other (cold riveting, hot riveting);

[0123] Usage: Riveting is classified into two categories, namely cold riveting (L) and hot riveting (R).

[0124] In the process of hot riveting, the rivets do not need to be heated and are directly riveted by the riveting tool to complete the riveting formation. In the process of hot riveting, the rivets need to be heated to a certain temperature (temperature control is one of the important riveting parameters) before being riveted by the riveting tool. Cold riveting and hot riveting are two different processes and cannot overlap each other. Figure 1 For R11-2 joints rated (P1), CR7620-08 rivets are used, which are cold riveted, denoted by (L). For example, ordinary solid rivets can be heated before riveting, denoted by R, or they can be directly extruded using a riveting machine, denoted by L.

[0125] The coverage rule corresponding to the degree of automation is that the type of automation degree is the same as the type of automation degree in the existing riveting process assessment;

[0126] It should be noted that the same level of automation (manual, automatic, semi-automatic) can overlap each other. In the embodiment of the present application, the automation level of riveting can be divided into three categories, namely manual (M), semi-automatic (PM), and automatic (A). Among them, manual (M) refers to the riveting process through "manual installation of rivets + manual operation of equipment"; semi-automatic (PM) refers to the riveting process through "automatic installation of rivets by equipment + manual operation of equipment"; automatic (A) refers to the riveting process through "automatic installation of rivets by equipment + automatic riveting by riveting equipment". Manual, semi-automatic and automatic reflect different levels of riveting automation and cannot overlap each other. For example Figure 3 The R11-2 joint rated (P1) is manually riveted, indicated by (M). If automatic riveting equipment is used, which can automatically feed nails and automatically rivet, indicated by A, the rating (P1) cannot be covered and a re-riveting is required.

[0127] The coverage rule corresponding to the riveting method is that the riveting method type is the same as the riveting method type in the existing riveting process assessment.

[0128] It should be noted that the same type of riveting methods can overlap each other (dry riveting, wet riveting). For riveting with adhesive, the adhesive has a curing time. There are two riveting methods, dry riveting (Dr) and wet riveting (Wt). Wet riveting is to complete the riveting within the adhesive operating time (t1) after applying the adhesive, while dry riveting is to complete the riveting after the adhesive is completely cured (t2). Please refer to Figure 7 The relationship between the riveting method and the adhesive curing process is shown in the figure. Dry riveting and wet riveting are two different riveting processes and cannot overlap each other. Figure 3The R11-2 joint with medium assessment (P1) uses EP6250 structural adhesive (A1), with an operating time t1 of 4 hours and a curing time t2 of 48 hours. It adopts a dry riveting process, which is expressed as A1 (Dr). If the process to be developed requires riveting within the operating time, re-assessment is required (or matching the uncoated riveting process assessment items).

[0129] In one embodiment, the process of determining a target riveting process assessment covering each key element from a pre-established riveting process assessment database based on each key element in combination with pre-established coverage rules corresponding to each key element may include:

[0130] For each existing riveting process assessment in the pre-established riveting process assessment database, each key element of the existing riveting process assessment is compared with each key element information of the riveted structure to be assessed, and a comparison result corresponding to each key element is obtained;

[0131] When the comparison results corresponding to the key elements of the existing riveting process assessment respectively satisfy the corresponding coverage rules, the existing riveting process assessment is determined as the target riveting process assessment.

[0132] It should be noted that, based on the coverage rules for each key element information established above, when matching a target riveting process assessment from the riveting process assessment database, a pre-existing riveting process assessment whose key elements can cover all key elements of the riveted structure to be assessed can be identified from each pre-existing riveting process assessment stored in the riveting process assessment database, and this pre-existing riveting process assessment can be used as the target riveting process assessment. In other words, if each key element in the determined target riveting process assessment satisfies the coverage rules for the corresponding key elements in the riveted structure to be assessed, then this target riveting process assessment can be directly used as the riveting process assessment for the riveted structure to be assessed, eliminating the need for a new process assessment for the riveted structure to be assessed, thereby enabling a rapid and accurate determination of the riveting process assessment.

[0133] It should also be noted that in order to express the content of the riveting process assessment project intuitively and concisely and improve the efficiency of the determination of the riveting process assessment, in actual application, code naming rules for various key elements can be pre-established based on the assessment element matching conditions. Please refer to Table 2 for details: Table 2 Riveting process assessment project element code management table

[0134]

[0135]

[0136]

[0137] The concise expression of riveting process assessment items is as follows Figure 8 As shown, the codes for different assessment items are explained below.

[0138] For example, the code explanation of assessment item P1 is shown in Table 3: Table 3 Code explanation table for assessment item P1 For example, the code explanation of assessment item P2 is shown in Table 4: Table 4 Code explanation table for assessment item P2 For example, the code explanation of assessment item P3 is shown in Table 5: Table 5 Code explanation table for assessment item P3

[0139] In one embodiment, the process of determining a target riveting process assessment covering each key element from a pre-established riveting process assessment database based on each key element in combination with pre-established coverage rules corresponding to each key element may include:

[0140] Based on the preset code naming rules, according to the key element information corresponding to each process assessment item, determine the element information code corresponding to each key element information;

[0141] Combine the element information codes corresponding to each key element information according to the preset arrangement order of each key element information to obtain the code combination of the project to be evaluated;

[0142] Compare the code combination of the item to be assessed with the code combination of each assessment item of the existing riveting process assessment in the pre-established riveting process assessment database;

[0143] The existing riveting process assessment projects with the same assessment project code combination as the project code combination to be assessed shall be used as the target riveting process assessment.

[0144] It should be noted that in actual applications, the manufacturer does not need to be named. Instead, each first riveting process assessment that is identical to the manufacturer's information can be determined from the riveting process assessment database. For each key element of the riveted structure to be assessed, the element information code corresponding to each key element information can be obtained according to a preset code naming rule. Then, each element code information is combined in a preset order to obtain the code combination for the item to be assessed. The preset order can be the preset order of each key element information or the preset order of each process assessment item.

[0145] In actual applications, the key elements belonging to the same process assessment item can be combined to obtain assessment item codes, and these assessment item codes can be combined in a preset arrangement order, which can be a preset order of each assessment item code. For example, the assessment item codes of the assessment items P1 to P3 in the above tables are composed of the element information codes of each key element in a corresponding order. For example, in the order of joint type-material combination-rivet ring-adhesive-anti-corrosion-general rules, the assessment item codes corresponding to the joint type, material combination, rivet ring, adhesive, anti-corrosion, and general rules are combined in the preset order to obtain the combination of item codes to be assessed. For each existing riveting process assessment in the riveting process assessment database, a corresponding assessment item code combination obtained in the same manner may also be stored. This allows the code combination of the item to be assessed to be compared with the assessment item code combination of each first riveting process assessment in the pre-established riveting process assessment database. If a first riveting process assessment item exists whose assessment item code combination matches the code combination of the item to be assessed, the existing riveting process assessment item is used as the target riveting process assessment. In this embodiment, matching the assessment item codes allows for rapid and accurate determination of the target riveting process assessment, thereby improving the efficiency of determining the riveting process assessment.

[0146] In one embodiment, the method may further include:

[0147] The key element information of the riveted structure to be evaluated and the corresponding evaluation item code combination are stored in the riveting process evaluation database in correspondence with the determined target riveting process evaluation.

[0148] It is understandable that after determining the target riveting process assessment corresponding to the riveted structure to be assessed, the key element information of the riveted structure to be assessed and the corresponding assessment item code combination can be stored in the riveting process assessment database in correspondence with the determined target riveting process assessment, so as to make the riveting process assessment database more complete and quickly determine the riveting process assessment of other riveted structures to be assessed subsequently.

[0149] In one embodiment, the process of obtaining all element information of the riveted structure to be evaluated may include:

[0150] All element information of the riveted structure to be evaluated is extracted according to the riveting process data information of the riveted structure to be evaluated.

[0151] It can be understood that in this embodiment, all element information of the riveted structure to be evaluated can be extracted based on the riveting process data information of the riveted structure to be evaluated, so as to ensure that more complete and comprehensive element information can be obtained, which is conducive to extracting more accurate key element information, thereby determining a more accurate riveting process evaluation.

[0152] It should also be noted that when there is no riveting process assessment covering all key elements in the pre-established riveting process assessment database, each key element and the content to be assessed corresponding to each key element are output so that assessment verification can be performed based on each key element and the corresponding content to be assessed, and a riveting process assessment corresponding to the riveted structure to be assessed is obtained.

[0153] The following example illustrates how to classify the riveting process evaluation for riveted structures.

[0154] The riveting process qualification data can be entered into the riveting process qualification database (e.g. Figure 9 As shown in the figure, the data entered are all the information of the elements of the riveting process: parent material (i.e., connected material) elements: including material type, thickness, coating, prefabricated hole diameter, and surface treatment; adhesive: including adhesive model, glue application position, operating time, and curing time; hole making: including hole diameter, hole making method, hole making type, countersink diameter, and countersink method; rivet collar: including rivet type, rivet model, rivet diameter, clamping thickness, rivet material, and collar model; riveted joint: including joint design and joint preparation, where joint design includes joint code and joint summary. Figure 2 Elements, joint preparation includes two elements: schematic diagram and gap; riveting process: includes three aspects: riveting method, rivet gun information and riveting position, among which the riveting method includes four elements: installation method, riveting type, riveting classification and riveting mode; the rivet gun information includes four elements: rivet gun name, rivet gun model, gun head model and power mode; the riveting position includes one element: position name.

[0155] Furthermore, the system extracts key data for assessment matching from all factor information (e.g. Figure 10 As shown in Table 2), obtain the key element information and convert it into key element code according to the requirements of Table 2 (such as Figure 11 As shown in the figure), then combine the key elements into the evaluation project code combination according to the code and the preset order (such as Figure 12As shown), the assessment and inspection records of the riveted structure are entered into the riveted assessment database. The system can automatically generate an assessment form and output it in a predetermined format. When using this function, click the detailed summary function in the system, and the database automatically extracts all the key elements of the assessment in the system and outputs the data form (as shown). Figure 13 As shown in Figure 2), data collection is realized. The data collection process of each link is as follows: Figure 14 shown.

[0156] The following example analyzes the assessment coverage:

[0157] The system can realize the analysis of the coverage of riveting process assessment. You can choose to input the riveting assessment content (such as Figure 9 After the system has embedded the rule elements of the relevant riveting standards, the coverage is automatically calculated according to the requirements (rules in Table 1) and the assessment coverage is automatically output, such as Figure 15 In this embodiment, it is possible to quickly determine whether the riveted joint and the riveting process have been evaluated and verified. The riveted joint to be evaluated is input into the system. The system extracts the key element information to be evaluated based on the riveting information and compares it with the information in the riveting evaluation database. If there is a corresponding evaluation item in the riveting evaluation database, the system automatically displays the corresponding evaluation report item information and the relevant evaluation report; if there is no corresponding evaluation information in the evaluation database or some information cannot be matched, the system automatically generates a riveting process evaluation item code and the system displays a prompt that the process evaluation needs to be completed. For details of the process, see Figure 16 .

[0158] The following uses the R11-2 new joint as an example to illustrate the rapid assessment process of the riveting process:

[0159] Enter new riveting process data information (such as Figure 17 As shown in the figure), the system automatically extracts key element information, such as Figure 18 As shown, convert the key element information into the corresponding key element code (such as Figure 19 As shown in the figure), the system automatically generates the required assessment item code according to each key element code (such as Figure 20 The system automatically retrieves the riveting evaluation database (such as Figure 11 ) has completed the assessment data (that is, the riveting process assessment has been completed), and automatically compares it according to the coverage rules corresponding to the above-mentioned key element information. If it is determined that the assessment item P1 can support the riveting process, the riveting process assessment data that has successfully matched will be displayed (such as Figure 21 As shown in Table 10), if the material of the new riveting process is changed to aluminum alloy for t1 and the rest of the riveting data is the same as in Table 10, then the evaluation code produced is as follows: Figure 22If the match is unsuccessful, you can decide whether to add a new process assessment. If the match is successful, you can add the matched process assessment to the assessment data, as shown in the following example: Figure 23 As shown, the evaluation experiment can then be carried out to complete the entry of the riveting process evaluation report.

[0160] It should also be noted that, in this embodiment, combined with the above-mentioned content, the overall flow chart of riveting process assessment data collection, intelligent matching and assessment analysis is as follows: Figure 24 As shown, the specific process can refer to the above introduction, and this application will not go into details here.

[0161] It should also be noted that in actual applications, the process assessment database can realize the rapid collection of assessment factors and the rapid output of assessment factors of the same category. When using this function, first enter the assessment factors, extract the data of the same category from the database based on the factors of the data, and the system will collect and output them.

[0162] The present invention proposes 15 important evaluation variables in eight aspects, including riveting product manufacturers, joint types, connected materials, rivet collars, hole making, adhesives, corrosion protection and general processes, focusing on the riveting process. By identifying the important variables of the process, the riveting process evaluation projects can be scientifically and effectively formulated to ensure the process formulation and effective management of the riveting process; based on the characteristics of the important variables, the process evaluation coverage methods and principles are formulated to improve the versatility of the riveting process evaluation; at the same time, a process evaluation code management system is formulated to form a concise expression method for the evaluation code, which can quickly clarify and identify the content of the riveting process evaluation, and can also quickly locate the coverage of a certain riveting process evaluation.

[0163] By building a basic framework for process assessment, a riveting process assessment database was formed based on process assessment standard rules, and a process assessment database was designed. The use of the riveting process assessment database enables efficient collection of process assessment data and information, and can collect relevant data for a specific assessment factor and automatically generate a process assessment form. The use of the riveting process assessment database enables intelligent analysis of the scope of assessment factors and rapid intelligent determination of the riveting process, resolving the issues of heavy workload, low efficiency, and poor accuracy in riveting process analysis and determination, and achieving automatic, efficient, and accurate riveting process analysis and determination.
