Description

Technical Field

[0001] The present invention relates to the technical field of automobile assembly, and in particular to a method and system for determining an assembly plan of vehicle parts. Background Art

[0002] In the related technology, vehicle assembly plants are gradually using digital tools such as three-dimensional data to guide operators to establish assembly plans. Operators often obtain matching assembly process plans by disassembling three-dimensional data from the outside to the inside. However, in the actual assembly process, many problems that cannot be displayed by the data are prone to occur. That is, the assembly process plan directly formed by three-dimensional data is prone to unexpected problems, which affects the operator's assembly of the vehicle and subsequent maintenance. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a method for determining an assembly scheme of vehicle parts, which can form a preferred assembly scheme to facilitate the operator to perform assembly operations and subsequent maintenance on the vehicle.

[0004] The invention also provides an assembly plan determination system.

[0005] The present invention also provides a computer-readable storage medium.

[0006] A method for determining an assembly scheme of vehicle parts according to an embodiment of a first aspect of the present invention is applied to the assembly of vehicle parts, and includes:

[0007] Extracting a first characteristic element of a vehicle component, and matching it in a preset network database according to the first characteristic element, to obtain at least one network matching solution and a first matching degree corresponding to the network matching solution;

[0008] Extracting a second characteristic element of the vehicle component, and matching in a preset internal database according to the second characteristic element to obtain at least one internal matching solution and a second matching degree corresponding to the internal matching solution;

[0009] The network matching scheme with the highest first matching degree is selected as the first alternative scheme, the internal matching scheme with the highest second matching degree is selected as the second alternative scheme, and the one with the highest matching degree between the first alternative scheme and the second alternative scheme is selected as the assembly scheme for vehicle parts.

[0010] The method for determining an assembly scheme for vehicle parts according to an embodiment of the present invention has at least the following beneficial effects: for vehicle parts, the method for determining an assembly scheme for vehicle parts can extract a first characteristic element and a second characteristic element from the vehicle parts, and perform network matching in a preset network database according to the first characteristic element to obtain at least one network matching scheme and a first matching degree corresponding to the network matching scheme, that is, to obtain a network matching scheme for horizontal comparison and reference by network search; the method for determining an assembly scheme for vehicle parts performs internal matching in a preset internal database according to the second characteristic element to obtain at least one internal matching scheme and a second matching degree corresponding to the internal matching scheme, that is, to obtain an internal matching scheme for vertical comparison and reference by enterprise internal information search; then the method for determining an assembly scheme for vehicle parts selects a scheme with the highest matching degree from the first alternative scheme and the second alternative scheme as the assembly scheme, that is, to form an assembly scheme for the corresponding vehicle parts; the formed assembly scheme can be selected by an operator or compared with the original scheme to optimize the assembly process of the vehicle parts, so as to eliminate assembly problems of the vehicle in advance, so as to facilitate the operator to perform assembly operations and subsequent maintenance on the vehicle.

[0011] According to some embodiments of the present invention, extracting a first characteristic element of a vehicle component, and matching in a preset network database according to the first characteristic element, obtaining at least one network matching solution and a first matching degree corresponding to the network matching solution, includes:

[0012] Extracting a plurality of non-repeating first characteristic elements of vehicle parts, wherein the first characteristic elements include at least one of a part name, an assembly position, a matching connector, an appearance, and an assembly fixing point;

[0013] Matching a network matching solution in a network database according to the plurality of first characteristic elements, wherein the network matching solution has at least one first matching element that matches the first characteristic element;

[0014] The ratio of the number of first matching elements to the number of first characteristic elements is calculated to obtain a first matching degree of the network matching solution.

[0015] Specifically, when extracting the first characteristic element, the method for determining the assembly scheme of vehicle parts can extract multiple non-repetitive first characteristic elements for the vehicle parts, and the first characteristic element includes at least one of the part name, assembly position, matching connector, appearance and assembly fixing point. The method for determining the assembly scheme of vehicle parts matches the multiple first characteristic elements in a network database to obtain a network matching scheme having at least one first matching element that matches the first characteristic element, so that the operator can refer to the previous assembly scheme to reduce defects in vehicle assembly. By calculating the ratio of the number of first matching elements to the number of first characteristic elements, the first matching degree of the network matching scheme is obtained. By calculating the first matching degree, it is helpful to select the scheme with the highest matching degree from multiple network matching schemes and internal matching schemes, which plays a screening role and helps the operator to obtain the preferred assembly scheme to achieve the assembly and subsequent maintenance of vehicle parts.

[0016] According to some embodiments of the present invention, extracting the second characteristic element of the vehicle parts, and matching in a preset internal database according to the second characteristic element to obtain at least one internal matching scheme and a second matching degree corresponding to the internal matching scheme includes:

[0017] Extracting a plurality of non-repeating second characteristic elements of vehicle parts, the second characteristic elements comprising at least one of a part name, an internal project number, a vehicle model, borrowing information, and a matching connector;

[0018] Matching an internal matching solution in an internal database according to the plurality of second characteristic elements, wherein the internal matching solution has at least one second matching element that matches the second characteristic element;

[0019] The ratio of the number of the second matching elements to the number of the second characteristic elements is calculated to obtain a second matching degree of the internal matching solution.

[0020] Specifically, when extracting the second characteristic element, the method for determining the assembly scheme of vehicle parts can extract multiple non-repeating second characteristic elements of vehicle parts, and the second characteristic element includes at least one of the part name, internal project number, vehicle model, borrowing information and matching connectors. The method for determining the assembly scheme of vehicle parts matches the multiple second characteristic elements in the internal database to obtain an internal matching scheme having at least one second matching element that matches the second characteristic element, so that the operator can refer to the prior assembly scheme within the enterprise to reduce defects in vehicle assembly. By calculating the ratio of the number of second matching elements to the number of second characteristic elements, the second matching degree corresponding to the internal matching scheme is obtained. By calculating the second matching degree, it is helpful to select the scheme with the highest matching degree from multiple internal matching schemes and internal matching schemes, which plays a screening role and helps the operator to obtain the preferred assembly scheme to achieve assembly and subsequent maintenance of vehicle parts.

[0021] According to some embodiments of the present invention, the method for determining an assembly plan for vehicle parts further includes:

[0022] Matching tooling in the preset tooling database according to the types and appearance characteristics of vehicle parts;

[0023] The connectors required for assembling vehicle parts are extracted from the assembly plan, and the tooling is matched in the tooling database according to the type and appearance characteristics of the connectors.

[0024] After the assembly scheme for vehicle parts is output in the network database and the internal database, in order to assist the operator in selecting the corresponding tooling, so as to enhance the guidance effect on the operator and improve the operator's assembly and maintenance efficiency of the vehicle, the assembly scheme for vehicle parts and components is determined. The method extracts the connectors required for the vehicle parts, and then automatically matches the corresponding tooling in the tooling database according to the types and appearance characteristics of the vehicle parts and connectors, so that the operator can intuitively know the tooling corresponding to the assembly scheme for the vehicle parts and components, and which tooling corresponds to the connectors used in the assembly scheme, so as to improve the operator's efficiency in actual assembly. The method automatically matches the connectors according to the vehicle parts and connectors, which is conducive to enhancing the guidance effect on the operator.

[0025] According to some embodiments of the present invention, the method for determining an assembly plan for vehicle parts further includes:

[0026] After matching the tooling, modify the tooling according to the shape and size of vehicle parts or connectors to obtain trial tooling;

[0027] The assembly plan is disassembled into multiple work steps, and the tooling or trial tooling is integrated into the corresponding work steps to obtain the assembly process flow.

[0028] Taking into account that the tooling sizes existing in the tooling database may be difficult to meet the assembly requirements of vehicle parts and connectors, the method for determining the assembly scheme for vehicle parts can modify the tooling according to the shape or size of the connector or vehicle part after matching the tooling according to the connector. That is, when the type of tooling remains unchanged, the tooling is modified according to the size of the connector or vehicle part to obtain a trial tooling suitable for the connector or vehicle part. The assembly scheme is disassembled into multiple steps, and the trial tooling is integrated into the corresponding steps to obtain the assembly process flow, thereby clarifying the assembly order of each connector, which is conducive to enhancing the guidance effect on the operator, so as to improve the operator's assembly efficiency of vehicle parts.

[0029] According to some embodiments of the present invention, the method for determining an assembly plan for vehicle parts further includes:

[0030] Obtain 3D models of vehicle parts and connectors, and conduct 3D simulation tests based on the assembly process;

[0031] In the simulation test, determining whether there is a fault in the simulation test, the fault including at least one of interference between two three-dimensional models, lack of assembly route in the three-dimensional model, lack of assembly space in the three-dimensional model, and inability of the three-dimensional model to use matching tooling or trial production tooling;

[0032] When there is a fault in the simulation test, the assembly process is judged to be unqualified.

[0033] Specifically, in order to identify whether there are unreasonable aspects in the assembly process and reduce the risk of operator misoperation, the method for determining the assembly scheme of vehicle parts can call or construct a three-dimensional model of vehicle parts and connectors, and conduct a three-dimensional simulation test according to the assembly process. In the simulation test, it is determined whether there is a fault, such as interference between two three-dimensional models, lack of assembly routes in the three-dimensional model, lack of assembly space in the three-dimensional model, and inability to use matching tooling or trial tooling for the three-dimensional model. When it is determined that there is a fault in the simulation test, the assembly process is determined to be unqualified, that is, there are unreasonable aspects in the assembly process. That is, the method for determining the assembly scheme of vehicle parts verifies the assembly process through simulation tests, thereby removing unreasonable assembly processes to eliminate defects formed during vehicle assembly in advance, so as to facilitate the operator to assemble the vehicle and perform subsequent maintenance.

[0034] According to some embodiments of the present invention, when there is a fault in the simulation test, determining that the assembly process is unqualified includes:

[0035] When the assembly process is unqualified, the assembly scheme corresponding to the unqualified assembly process is excluded, and re-matching is performed in the network database according to the first characteristic element, and re-matching is performed in the internal database according to the second characteristic element.

[0036] Specifically, when the method for determining the assembly scheme of vehicle parts determines that the assembly process is unqualified, the assembly scheme corresponding to the unqualified assembly process should be excluded, and then re-matched in the network database according to the first characteristic element, and re-matched in the internal database according to the second characteristic element, that is, after excluding the old assembly scheme, a new assembly scheme is re-formed to form an assembly scheme that provides guidance for vehicle parts. That is, the method for determining the assembly scheme of vehicle parts can verify the assembly process through simulation tests, thereby removing unreasonable assembly process flows, so as to eliminate defects formed during vehicle assembly in advance, so as to facilitate operators to perform assembly operations and subsequent maintenance on the vehicle.

[0037] According to some embodiments of the present invention, the method for determining an assembly plan for vehicle parts further includes:

[0038] Receive vehicle data and verify the format and naming of the vehicle data to verify whether there are any calling errors in the vehicle data;

[0039] When there is no call error in the whole vehicle data, the whole vehicle data is split to obtain multiple vehicle parts.

[0040] Considering that vehicle assembly plants currently usually provide three-dimensional vehicle data to guide operators to establish assembly plans, the method for determining the assembly plan of vehicle parts can verify the format and naming of the vehicle data after receiving the vehicle data, so as to verify whether there is a call error in the vehicle data. When there is no call error in the vehicle data, the vehicle data can be split to form multiple vehicle parts, or an assembly composed of multiple vehicle parts. By subsequently matching the vehicle parts and the assembly with the assembly plan, the formed assembly plan can be used by the operator for selection or comparison with the original plan to optimize the assembly process of the vehicle parts, so as to eliminate the assembly problems of the vehicle in advance and facilitate the operator to assemble the vehicle and perform subsequent maintenance.

[0041] The assembly scheme determination system according to the second embodiment of the present invention is applied to the assembly of vehicle parts, and includes:

[0042] A network database containing publicly available vehicle parts assembly plans;

[0043] Internal database, including vehicle parts assembly plans within the enterprise;

[0044] The algorithm module is configured to extract the first characteristic element and the second characteristic element of the vehicle parts, perform matching in the network database according to the first characteristic element, obtain at least one network matching scheme and a first matching degree corresponding to the network matching scheme, perform matching in the internal database according to the second characteristic element, obtain at least one internal matching scheme and a second matching degree corresponding to the internal matching scheme, select the network matching scheme with the highest first matching degree as the first alternative scheme, select the internal matching scheme with the highest second matching degree as the second alternative scheme, and select the one with the highest matching degree between the first alternative scheme and the second alternative scheme as the assembly scheme of the vehicle parts.

[0045] The assembly scheme determination system according to the embodiment of the present invention has at least the following beneficial effects: the assembly scheme determination system includes a network database and an internal database, the network database contains the assembly schemes of vehicle parts disclosed by the industry, and the internal database contains the assembly schemes of vehicle parts within the enterprise. For vehicle parts, the assembly scheme determination system can extract the first characteristic element and the second characteristic element of the vehicle parts through the algorithm module, and perform network matching in the network database according to the first characteristic element to obtain at least one network matching scheme and a first matching degree corresponding to the network matching scheme, that is, through network search, to obtain a network matching scheme for horizontal comparison and reference. The assembly scheme determination system can perform internal matching in the internal database according to the second characteristic element through the algorithm module to obtain at least one internal matching scheme and a second matching degree corresponding to the internal matching scheme, that is, through enterprise internal information search, to obtain an internal matching scheme for vertical comparison and reference. Then, the assembly scheme determination system selects the one with the highest matching degree from the first alternative scheme and the second alternative scheme as the assembly scheme, that is, to form an assembly scheme corresponding to the vehicle parts. The formed assembly scheme can be selected by the operator or compared with the original scheme to optimize the assembly process of the vehicle parts, so as to eliminate the assembly problems of the vehicle in advance, so as to facilitate the operator to perform assembly operations and subsequent maintenance on the vehicle.

[0046] According to the computer-readable storage medium of the embodiment of the third aspect of the present invention, the computer-readable storage medium stores computer-executable instructions, and the computer-executable instructions are used to enable a computer to execute the method for determining the assembly plan of vehicle parts as shown in any one of the first aspects.

[0047] According to the assembly scheme determination system of the embodiment of the present invention, there are at least the following beneficial effects: the computer executable instructions are used to enable the computer to execute the assembly scheme determination method for vehicle parts as shown in any one of the first aspects, for vehicle parts, the assembly scheme determination method for vehicle parts can extract the first characteristic element and the second characteristic element for the vehicle parts, and perform network matching in a preset network database according to the first characteristic element to obtain at least one network matching scheme and a first matching degree corresponding to the network matching scheme, that is, to obtain a network matching scheme for horizontal comparison reference by network search, the assembly scheme determination method for vehicle parts performs internal matching in a preset internal database according to the second characteristic element to obtain at least one internal matching scheme and a second matching degree corresponding to the internal matching scheme, that is, to obtain an internal matching scheme for vertical comparison reference by enterprise internal information search, and then the assembly scheme determination method for vehicle parts selects the one with the highest matching degree from the first alternative scheme and the second alternative scheme as the assembly scheme, that is, to form an assembly scheme for the corresponding vehicle parts, and the formed assembly scheme can be selected by the operator or compared with the original scheme to optimize the assembly process of the vehicle parts, so as to eliminate the assembly problems of the vehicle in advance, so as to facilitate the operator to perform assembly operations and subsequent maintenance on the vehicle.

[0058] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0059] In the description of the present invention, it should be understood that descriptions involving orientation, such as orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0060] In the description of the present invention, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0061] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0062] In the related technology, vehicle assembly plants are gradually using digital tools such as three-dimensional data to guide operators to establish assembly plans. Operators often obtain matching assembly process plans by disassembling three-dimensional data from the outside to the inside. However, in the actual assembly process, many data cannot be displayed. That is, the assembly process plan directly formed by three-dimensional data has the defect of being too idealistic.

[0063] For example, two parts can ideally fit together in a 3D model, but in actual assembly, they cannot be assembled due to limitations such as thermal expansion and contraction, assembly errors, and deformation. For another example, the assembly process scheme obtained by disassembling the 3D model from the outside to the inside in the related art often has the defect that some connectors are assembled in the wrong direction, which can easily lead to the problem of wrong assembly by the operator.

[0064] Reference Figures 1 to 8 As shown, a method for determining an assembly scheme of vehicle parts according to an embodiment of the present invention is applied to the assembly of vehicle parts. The method for determining an assembly scheme of vehicle parts comprises the following steps:

[0065] Step S100, extracting a first characteristic element of a vehicle component, and matching it in a preset network database according to the first characteristic element to obtain at least one network matching solution and a first matching degree corresponding to the network matching solution;

[0066] Step S200, extracting the second characteristic element of the vehicle component, and matching in a preset internal database according to the second characteristic element to obtain at least one internal matching solution and a second matching degree corresponding to the internal matching solution;

[0067] Step S300, selecting the network matching solution with the highest first matching degree as the first alternative solution, selecting the internal matching solution with the highest second matching degree as the second alternative solution, and selecting the solution with the highest matching degree between the first alternative solution and the second alternative solution as the assembly solution for vehicle parts.

[0068] Reference Figure 1 and Figure 2 As shown, in step S100 and step S200, the preset network database contains the vehicle parts assembly scheme disclosed by the industry, and the preset internal database contains the vehicle parts assembly scheme within the enterprise, so as to facilitate matching in the network database and the internal database according to the vehicle parts.

[0069] Reference Figure 1 and Figure 2 As shown in Figure 1, the online database mainly includes publicly available vehicle models, characteristic shapes of parts, assembly process methods and cases in the industry. The internal database mainly includes the vehicle models previously developed within the enterprise and the predecessor products of the vehicle models.

[0070] Reference Figure 1 and Figure 2As shown, in step S100, for vehicle parts, the method for determining the assembly scheme of vehicle parts can extract a first characteristic element from the vehicle parts, and perform network matching in a network database according to the first characteristic element to obtain at least one network matching scheme and a first matching degree corresponding to the network matching scheme, that is, to obtain a network matching scheme for horizontal comparison and reference through network search.

[0071] Reference Figure 1 and Figure 2 As shown, the method for determining the assembly plan of vehicle parts can compare the assembly methods and operation difficulty coefficients of other vehicle models on the network, thereby forming a network matching plan for the operator to refer to.

[0072] Reference Figure 1 and Figure 2 As shown in step S200, for vehicle parts, the method for determining the assembly scheme of vehicle parts can extract second characteristic elements from the vehicle parts, and perform internal matching in the internal database based on the second characteristic elements to obtain at least one internal matching scheme and a second matching degree corresponding to the internal matching scheme, that is, to obtain an internal matching scheme for vertical comparison and reference by searching internal information of the enterprise.

[0073] Reference Figure 1 and Figure 2 As shown, the method for determining the assembly plan of vehicle parts can compare the vehicle model assembly plan and the operation difficulty coefficient within the company, so as to form an internal matching plan for the operator to refer to.

[0074] Reference Figure 1 and Figure 2 As shown in step S300, the method for determining the assembly scheme of vehicle parts obtains several network matching schemes and internal matching schemes after matching the first characteristic element and the second characteristic element. In order to enhance the guidance effect on the operator, the method for determining the assembly scheme of vehicle parts selects the network matching scheme with the highest first matching degree as the first alternative scheme, selects the internal matching scheme with the highest second matching degree as the second alternative scheme, and selects the one with the highest matching degree between the first alternative scheme and the second alternative scheme as the assembly scheme of the vehicle parts, thereby forming an assembly scheme for the corresponding vehicle parts.

[0075] Reference Figure 1 and Figure 2The assembly scheme formed by the assembly scheme determination method for the vehicle parts shown in the figure can be directly selected by the operator. By drawing on the existing assembly methods, it is helpful to reduce the defects caused by over-idealization of data, that is, to eliminate the defects of the vehicle in the assembly process, so as to avoid the problem of wrong assembly or low assembly efficiency by the operator. The operator can also compare the formed assembly scheme with the original scheme to optimize the original scheme, that is, to provide data support for the optimization and improvement of the original scheme, so as to eliminate the assembly problems of the vehicle in advance and facilitate the operator to perform assembly operations and subsequent maintenance on the vehicle.

[0076] Reference Figure 1 and Figure 8 As shown, it is understandable that, considering that the current vehicle assembly plant usually provides three-dimensional data of the whole vehicle to guide the operator to establish an assembly plan; the method for determining the assembly plan of vehicle parts also includes the following steps:

[0077] Step S510, receiving vehicle data, and verifying the format and naming of the vehicle data to verify whether there is a call error in the vehicle data;

[0078] Step S520, when there is no call error in the whole vehicle data, the whole vehicle data is split to obtain multiple vehicle parts.

[0079] Reference Figure 1 and Figure 8 As shown, after receiving the whole vehicle data, the method for determining the assembly scheme of vehicle parts can verify the format and naming of the whole vehicle data, so as to verify whether there is a calling error in the whole vehicle data. If it is verified that the whole vehicle data has a calling error defect, a prompt signal is sent to the user, such as a text prompt, a sound prompt, etc., to prompt the user that there is a problem with the whole vehicle data called in. The method for determining the assembly scheme of vehicle parts can quickly verify data errors or data mismatches by verifying the whole vehicle data, thereby quickly checking whether the parts list or the parts assembly is correct.

[0080] Reference Figure 1 and Figure 8 As shown, when there is no call error in the whole vehicle data, the method for determining the assembly scheme of the vehicle parts can split the whole vehicle data to form multiple vehicle parts, or an assembly composed of multiple vehicle parts, and then match the vehicle parts and the assembly with the assembly scheme. The formed assembly scheme can be used by the operator for selection or comparison with the original scheme to optimize the assembly process of the vehicle parts, so as to eliminate the assembly problems of the vehicle in advance and facilitate the operator to assemble the vehicle and perform subsequent maintenance.

[0081] Reference Figure 1 and Figure 3As shown, it is understandable that the method for determining the assembly scheme of vehicle parts in step S100 further includes the following steps:

[0082] Step S110, extracting a plurality of non-repetitive first characteristic elements of vehicle parts, wherein the first characteristic elements include at least one of the part name, assembly position, matching connector, shape and assembly fixing point;

[0083] Step S120, matching a network matching solution in a network database according to the plurality of first characteristic elements, wherein the network matching solution has at least one first matching element that matches the first characteristic element;

[0084] Step S130, calculating the ratio of the number of first matching elements to the number of first characteristic elements to obtain a first matching degree of the network matching solution.

[0085] Reference Figure 1 and Figure 3 As shown, specifically, when extracting the first characteristic element, the method for determining the assembly scheme of vehicle parts can extract multiple non-repetitive first characteristic elements of vehicle parts, and the first characteristic element includes at least one of the part name, assembly position, matching connectors, appearance and assembly fixing points.

[0086] Reference Figure 1 and Figure 3 As shown, the method for determining the assembly scheme of vehicle parts matches multiple first characteristic elements in a network database to obtain a network matching scheme having at least one first matching element that matches the first characteristic element, so that the operator can refer to the previous assembly scheme to reduce the defects of vehicle assembly. The first matching degree is obtained by the ratio of the number of first matching elements to the number of first characteristic elements. The calculation of the first matching degree is conducive to selecting the scheme with the highest matching degree from multiple network matching schemes and internal matching schemes, which plays a role of screening and helps the operator to obtain the preferred assembly scheme to realize the assembly and subsequent maintenance of vehicle parts.

[0087] Reference Figure 1 and Figure 3 As shown, for example, the method for determining the assembly scheme of vehicle parts extracts five first characteristic elements from the vehicle parts, and the five first characteristic elements are the name of the part, the assembly position, the matching connector, the shape and the assembly fixing point. The method for determining the assembly scheme of vehicle parts performs matching in the network database according to the five characteristic elements. If one network matching scheme has four first matching features that match the first characteristic elements, the matching degree of the network matching scheme is calculated to be 80%.

[0088] The following description takes the door handle as an example of the part to be assembled. The five first characteristic elements extracted from the door handle are the name keywords of the door handle, being assembled on the door, being movably connected to the door through elastic parts, being curved, and being assembled in the middle area of ​​the outer side of the door.

[0089] It should be understood that after extracting the first characteristic elements from the vehicle parts, the method for determining the assembly scheme of the vehicle parts can match them in the network database according to semantic recognition or algorithm matching, and output the matching degree of the network matching scheme according to the semantic recognition method.

[0090] Reference Figure 1 and Figure 4 As shown, it is understandable that the method for determining the assembly scheme of vehicle parts in step S200 further includes the following steps:

[0091] Step S210, extracting a plurality of non-repeating second characteristic elements of vehicle parts, the second characteristic elements including at least one of a part name, an internal project number, a vehicle model, borrowing information, and a matching connector;

[0092] Step S220, matching an internal matching solution in an internal database according to the plurality of second characteristic elements, wherein the internal matching solution has at least one second matching element that matches the second characteristic element;

[0093] Step S220 , calculating the ratio of the number of second matching elements to the number of second characteristic elements, and obtaining a second matching degree of the internal matching solution.

[0094] Reference Figure 1 and Figure 4 As shown, specifically, when extracting the second characteristic element, the method for determining the assembly scheme of vehicle parts can extract multiple non-repeating second characteristic elements of vehicle parts, and the second characteristic element includes at least one of the part name, internal project number, vehicle model, borrowing information and matching connectors. The borrowing information is whether to borrow other design schemes within the enterprise.

[0095] Reference Figure 1 and Figure 4As shown, the method for determining the assembly scheme of vehicle parts matches multiple second characteristic elements in an internal database to obtain an internal matching scheme having at least one second matching element that matches the second characteristic element, so that the operator can refer to the previous assembly scheme within the enterprise to reduce the defects of vehicle assembly. The second matching degree is obtained by calculating the ratio of the number of second matching elements to the number of second characteristic elements. The calculation of the second matching degree is conducive to selecting the scheme with the highest matching degree from multiple internal matching schemes and internal matching schemes, which plays a role of screening and helps the operator to obtain the preferred assembly scheme to realize the assembly and subsequent maintenance of vehicle parts.

[0096] Reference Figure 1 and Figure 4 As shown, for example, the method for determining the assembly scheme of vehicle parts extracts five second characteristic elements from the vehicle parts, and the five second characteristic elements are the part name, internal project number, vehicle model, borrowing information and matching connectors. The method for determining the assembly scheme of vehicle parts performs matching in the internal database according to the five characteristic elements. If one internal matching scheme has three second matching elements that match the second characteristic elements, the matching degree of the internal matching scheme is calculated to be 60%.

[0097] Reference Figure 1 and Figure 4 As shown, the following explanation is given by taking the part to be assembled as a door handle as an example. The five second characteristic elements extracted from the door handle are the name of the door handle, the project number, the model number of the door handle that has been used in the past, the borrowing information of the door handle, and the active connection with the door through the elastic part.

[0098] Reference Figure 1 and Figure 5 As shown, it can be understood that the method for determining the assembly scheme of vehicle parts further includes:

[0099] Step S410, matching tooling in a preset tooling database according to the type and appearance characteristics of vehicle parts;

[0100] Step S420: extracting connectors required for assembling vehicle parts from the assembly plan, and matching tooling in a tooling database according to the types and appearance features of the connectors.

[0101] Reference Figure 1 and Figure 5 As shown, after the method for determining the assembly scheme of vehicle parts outputs the assembly scheme in the network database and the internal database, in order to assist the operator in selecting the corresponding tooling, so as to enhance the guidance effect on the operator and improve the assembly and maintenance efficiency of the vehicle, the method for determining the assembly scheme of vehicle parts needs to match the tooling from the tooling database containing multiple toolings.

[0102] Reference Figure 1 and Figure 5 As shown, the method for determining the assembly scheme of vehicle parts can match the tooling in the tooling database according to the type and appearance characteristics of the vehicle parts, extract the connectors required for assembling the vehicle parts in the selected assembly scheme, and then automatically match the corresponding tooling in the tooling database according to the type and appearance characteristics of the connectors, so that the operator can intuitively know the tooling corresponding to the vehicle parts and the tooling corresponding to the connectors used in the assembly scheme, so as to improve the operator's efficiency in actual assembly. The method for determining the assembly scheme of vehicle parts automatically matches the connectors according to the vehicle parts and the connectors, which is conducive to enhancing the guidance effect on the operator.

[0103] Reference Figure 1 and Figure 5 As shown, vehicle parts that are larger in size (air springs, control arms, etc.) or smaller in size (certain special position gaskets, window sound insulation cotton, etc.) require special tooling. The method for determining the assembly plan of the vehicle parts is through matching the assembly plan, matching through software algorithms or designing tooling suitable for the tooling to be assembled.

[0104] Reference Figure 1 and Figure 6 As shown, it is understandable that, considering that the tooling dimensions existing in the tooling database may be difficult to meet the assembly requirements of the connector, the method for determining the assembly plan of the vehicle parts further includes:

[0105] Step S430, after the tooling is matched, the tooling is modified according to the shape and size of the vehicle parts or connectors to obtain a trial tooling;

[0106] Step S440, decomposing the assembly plan into multiple steps, and integrating the tooling or trial-production tooling into the corresponding steps to obtain the assembly process flow.

[0107] Reference Figure 1 and Figure 6 As shown, after matching the tooling according to the connector, the method for determining the assembly scheme of vehicle parts can modify the tooling according to the shape and size of the vehicle parts to obtain a trial-produced tooling corresponding to the vehicle parts, and modify the tooling according to the shape or size of the connector to obtain a trial-produced tooling corresponding to the connector, that is, when the type of tooling remains unchanged, the tooling is modified according to the size of the vehicle parts or connectors to obtain a trial-produced tooling that is compatible with the vehicle parts and connectors, and the assembly scheme is disassembled into multiple steps, and the trial-produced tooling is combined with the corresponding steps to obtain the assembly process flow, thereby clarifying the assembly sequence of each connector, which is conducive to enhancing the guidance effect on the operator, so as to improve the operator's assembly efficiency of vehicle parts.

[0108] Reference Figure 1 and Figure 6 As shown, for example, when the vehicle parts are tires, the tooling is selected according to the name keywords and appearance characteristics of the tires. The corresponding tooling can be a tooling for holding up the tires. Then the connecting piece connecting the wheel to the vehicle is a screw, and the corresponding screwdriver is matched according to the screw as the tooling. Assuming that the screw is a special specification, that is, the size of the screw is unique compared to the previously applied threaded parts, the original screwdriver can be modified according to the size of the screw, so that the modified trial tooling can be suitable for the connection of the screw.

[0109] It should be noted that the method for determining the assembly plan of vehicle parts only requires the modification of tooling for special connectors and vehicle parts. For the connection of connectors and vehicle parts of ordinary specifications, the tooling in the tooling database can be directly called.

[0110] Reference Figure 1 and Figure 7 As shown, it can be understood that the method for determining the assembly scheme of vehicle parts further includes:

[0111] Step S450, obtaining three-dimensional models of vehicle parts and connectors, and performing three-dimensional simulation tests according to the assembly process;

[0112] Step S460, in the simulation test, determining whether there is a fault in the simulation test, the fault including at least one of interference between two three-dimensional models, lack of assembly route in the three-dimensional model, lack of assembly space in the three-dimensional model, and inability of the three-dimensional model to use matching tooling or trial-production tooling;

[0113] Step S470: When there is a fault in the simulation test, the assembly process is determined to be unqualified.

[0114] Reference Figure 1 and Figure 7 As shown, specifically, in order to screen out unreasonable assembly process flows and reduce the risk of operator misoperation, the method for determining the assembly plan of vehicle parts can call or construct three-dimensional models of vehicle parts and connectors, and conduct three-dimensional simulation tests according to the assembly process flow. In the simulation test, it is determined whether there is a fault in the simulation test, such as interference between two three-dimensional models, lack of assembly routes in the three-dimensional model, lack of assembly space in the three-dimensional model, or inability to use matching tooling for the three-dimensional model.

[0115] Reference Figure 1 and Figure 7As shown, when the method for determining the assembly scheme of vehicle parts determines that there is a fault in the simulation test, the assembly process is determined to be unqualified, that is, there is an unreasonableness in the assembly process. That is, the method for determining the assembly scheme of vehicle parts can verify the assembly process through a simulation test, thereby removing the unreasonable assembly process, so as to eliminate defects formed during vehicle assembly in advance, so as to facilitate the operator to perform assembly operations and subsequent maintenance on the vehicle.

[0116] Reference Figure 1 and Figure 7 As shown, the method for determining the assembly scheme of vehicle parts can adopt a secondary verification method when conducting a simulation test on the assembly process flow, that is, repeating the simulation test on the assembly process flow that is judged to be unqualified. When both simulation tests are judged to be unqualified, it is determined that the original assembly scheme is unreasonable and needs to be eliminated.

[0117] Reference Figure 1 and Figure 7 As shown, it can be understood that the method for determining the assembly scheme of vehicle parts further includes the following steps:

[0118] Step S480, when the assembly process flow is unqualified, the assembly scheme corresponding to the unqualified assembly process flow is excluded, and re-matching is performed in the network database according to the first characteristic element, and re-matching is performed in the internal database according to the second characteristic element.

[0119] Reference Figure 1 and Figure 7 As shown, specifically, when the assembly process flow is determined to be unqualified, the method for determining the assembly scheme of the vehicle parts should exclude the assembly scheme corresponding to the unqualified assembly process flow, and then re-match in the network database according to the first characteristic element, and re-match in the internal database according to the second characteristic element, that is, after excluding the old assembly scheme, a new assembly scheme is re-formed to ensure that the corresponding vehicle parts have a guided assembly scheme.

[0120] Reference Figure 1 and Figure 7 As shown, the method for determining the assembly scheme of vehicle parts can verify the formed assembly process flow through simulation tests, thereby removing unreasonable assembly process flows and eliminating defects formed during vehicle assembly in advance, so as to facilitate operators to perform assembly operations and subsequent maintenance on the vehicle.

[0121] Reference Figure 1 and Figure 7As shown, after the assembly scheme is re-matched, the re-matched assembly scheme can be disassembled into an assembly process flow, and a simulation test is performed on the assembly process flow. If the same vehicle part has two unqualified assembly schemes matched, a prompt is issued to the user, and the vehicle part is skipped and the next vehicle part is matched. For an assembly with multiple assembly parts, it can ensure that most vehicle parts can be matched automatically.

[0122] Reference Figure 1 As shown, an embodiment of the present invention further provides an assembly scheme determination system, which is applied to the assembly of vehicle parts, and includes:

[0123] A network database containing publicly available vehicle parts assembly plans;

[0124] Internal database, including vehicle parts assembly plans within the enterprise;

[0125] The algorithm module is configured to extract the first characteristic element and the second characteristic element of the vehicle parts, perform matching in the network database according to the first characteristic element, obtain at least one network matching scheme and a first matching degree corresponding to the network matching scheme, perform matching in the internal database according to the second characteristic element, obtain at least one internal matching scheme and a second matching degree corresponding to the internal matching scheme, select the network matching scheme with the highest first matching degree as the first alternative scheme, select the internal matching scheme with the highest second matching degree as the second alternative scheme, and select the one with the highest matching degree between the first alternative scheme and the second alternative scheme as the assembly scheme of the vehicle parts.

[0126] Reference Figure 1As shown, the assembly scheme determination system includes a network database and an internal database, the network database contains the assembly schemes of vehicle parts disclosed by the industry, and the internal database contains the assembly schemes of vehicle parts within the enterprise. For vehicle parts, the assembly scheme determination system can extract the first characteristic element and the second characteristic element of the vehicle parts through the algorithm module, and perform network matching in the network database according to the first characteristic element to obtain at least one network matching scheme and a first matching degree corresponding to the network matching scheme, that is, through network search, to obtain a network matching scheme for horizontal comparison reference. The assembly scheme determination system can perform internal matching in the internal database according to the second characteristic element through the algorithm module to obtain at least one internal matching scheme and a second matching degree corresponding to the internal matching scheme, that is, through enterprise internal information search, to obtain an internal matching scheme for vertical comparison reference. Then, the assembly scheme determination system selects the one with the highest matching degree from the first alternative scheme and the second alternative scheme as the assembly scheme, that is, to form an assembly scheme corresponding to the vehicle parts. The formed assembly scheme can be selected by the operator or compared with the original scheme to optimize the assembly process of the vehicle parts, so as to eliminate the assembly problems of the vehicle in advance, so as to facilitate the operator to perform assembly operations and subsequent maintenance on the vehicle.

[0127] Reference Figure 1 As shown, it is understandable that the assembly solution determination system includes a monitoring mechanism processing subsystem and a database subsystem, and the monitoring mechanism processing subsystem interacts with the database subsystem. The assembly solution determination system can use two controllers to control the monitoring mechanism processing subsystem and the database subsystem respectively.

[0128] Reference Figure 1 As shown, the database subsystem includes a network database, an internal database, a tooling database, and an assembly process flow database. The network database and the internal database are constructed according to the requirements of step S100 and step S200 in the above embodiment. The tooling database is constructed according to the requirements of step S410 in the above embodiment. Step S440 in the above embodiment can disassemble the assembly plan according to the content of the assembly process flow database. The assembly process flow database contains the disassembly plan of the corresponding vehicle parts.

[0129] Reference Figure 1 As shown, the assembly plan determination system can implement steps S510 and S520 shown in the above embodiment according to the monitoring management module to verify the format and naming of the whole vehicle data, so as to verify whether there is a calling error in the whole vehicle data. If it is verified that the whole vehicle data has a calling error defect, a prompt signal is sent to the user, such as a text prompt, a sound prompt, etc., to prompt the user that the whole vehicle data called in has a defect.

[0130] Reference Figure 1 As shown, the assembly scheme determination system can match, merge and output the network database, internal database, tooling database and assembly process flow database according to the algorithm module, thereby implementing steps S110, step S120, step S130, step S210, step S220, step S230, step S410, step S420, step S430 and step S440 shown in the above embodiment.

[0131] Reference Figure 1 As shown, the assembly scheme determination system can implement steps S450, S460 and S470 shown in the above embodiment according to the fault diagnosis module, and verify the formed assembly process flow through simulation tests, so as to remove unreasonable assembly process flows, so as to eliminate defects formed during vehicle assembly in advance, so as to facilitate the operator to perform assembly operations and subsequent maintenance on the vehicle.

[0132] Reference Figure 1 As shown, the assembly scheme determination system can implement step S480 shown in the above embodiment according to the reset module, and verify the formed assembly process flow through simulation tests, so as to remove unreasonable assembly process flows, so as to eliminate defects formed during vehicle assembly in advance, so as to facilitate the operator to perform assembly operations and subsequent maintenance on the vehicle.
