Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, specifically to a method, apparatus, and equipment for constructing and transferring data of a special small truck compartment across multiple systems. Background Technology

[0002] For the conventional process of light truck body engineering and packing: the body is a separate assembly. After the chassis front engineering is completed and production is completed, it is transferred to the body for assembly and then delivered. For the light truck manufacturing process planning: the body floor is a stamped part, produced in the stamping workshop and supplied for welding. The body floor is connected to the frame and painted together with BIW (body in white). The side and rear panels are rolled and welded as an assembly and painted in the body operation department, and then supplied to the final assembly workshop. Finally, the final assembly workshop completes the body assembly and delivers the vehicle.

[0003] Given the unique characteristics of small truck manufacturing, the interior manufacturing targets set by the Product Development (PD) goals (which refer to achieving project success through detailed project planning, project control, and teamwork) have been exceeded but not met. Through data-driven engineering analysis and benchmarking against the manufacturing processes of competing small and micro-truck series truck bodies in the industry, the manufacturing cost target must be achieved to meet the PD targets and keep the interior manufacturing costs within acceptable limits. By analyzing and reducing the overall value chain cost of truck body manufacturing, the strategy of integrating BIW (Body-Integrated Welding) into the entire truck body, with the second painting line as one of the most important directions, aims to reduce the energy consumption and process logistics losses associated with separately painting the side and rear panel assemblies.

[0004] However, due to significant changes in the process flow, the existing BOM (Bill of Materials) data structure is unresponsive, the SCF (Supply Chain Finance) production system cannot receive data to develop production and parts plans, and SAP (an enterprise resource planning system) also experiences data errors. Therefore, for the carriage business, the development and manufacturing data and flow processes need to be redesigned and implemented. Summary of the Invention

[0041] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0043] In a first aspect, embodiments of this application provide a method for constructing and transferring data from a special small truck compartment to multiple systems.

[0044] In one embodiment, reference is made to Figure 1 , Figure 1 This is a flowchart illustrating the method for constructing and transferring data across multiple systems for the special small truck compartments described in this application. Figure 1 As shown, the methods for constructing and transferring data across multiple systems for special small truck compartments include:

[0045] S1: The entire container is equipped with BIW through the VAN painting production line, and the manufacturing process and procedures of the small truck body are improved; VAN, also known as a van or minivan, is a type of vehicle mainly used for carrying goods and transporting multiple people.

[0046] In this application, the entire container is equipped with BIW through the VAN vehicle painting production line. The specific process includes: pre-painting assembly of the vehicle body, spot welding the vehicle body floor to the BIW chassis, and pre-painting assembly of the side and rear panels in the welding workshop.

[0047] This application improves the manufacturing process and procedures for the small truck body, specifically including the following improvements to the process planning:

[0048] S101: The carriage floor is a stamped part, produced in the stamping workshop and supplied for welding.

[0049] S102: Side and rear panel assembly (before painting) supplies welding equipment, welding equipment assembly is loaded into the whole box and then painted;

[0050] S103: The final assembly car is delivered after the accessories are assembled.

[0051] S2: EBOM re-plans and builds the structure of the carriage in the product BOM structural data, constructing the pre-painted and post-painted carriage assemblies;

[0052] EBOM is the data generated by the design department. Product designers design products based on customer orders or design requirements, generating information including product name, product structure, details, summary table, product instruction manual, packing list, etc. Most of this information is included in EBOM.

[0053] Furthermore, in one embodiment, the EBOM re-plans and reassembles the structure of the carriage in the product BOM structural data to construct the pre-painted and post-painted carriage assemblies. Specifically, the re-planning and reassembly of the carriage structure includes:

[0054] S201: For the current light truck model, build a virtual structure of the cargo box in the BOM and assign a virtual part number;

[0055] S202: Group the welded parts of the carriage under the second virtual part number structure;

[0056] The virtual part number includes a first virtual part number and a second virtual part number. The first virtual part number indicates that the carriage assembly has been painted, and the second virtual part number indicates that the carriage assembly has not been painted.

[0057] Specifically, the EBOM re-plans and rebuilds the structure of the cargo box in the product BOM structure data, constructing the pre-painted and pre-painted cargo box assemblies. For example, in model V0D1-101-002A, a virtual structure of the cargo box is built in the BOM, and virtual part numbers 8500014-VV0101 (indicating cargo box assembly - painted) and 8500016-VV0101 (indicating cargo box assembly - unpainted) are assigned. The welded parts of the cargo box are grouped under the 8500016-VV0101 structure, which fully reflects the process flow of welding, painting and assembly of the sub-assemblies of the small truck cargo box.

[0058] S3: MBOM expands and allocates the process route, adds hierarchical structure and part number to BOM, and synchronously adds production line code to SCF system;

[0059] Furthermore, in one embodiment, the MBOM expands and allocates the process route, specifically including:

[0060] S301: Based on the extended summary logic of the process route, assign the process route of MBOM and assign the paint-assembly mark to the first virtual part number.

[0061] S302: For parts of the carriage that are being welded, the corresponding process route is assigned, and all assembly routes are converted into welding marks and transmitted to the SCF system.

[0062] Specifically, MBOM expands and allocates process routes: In the implementation scheme of carriage component manufacturing, the process routes are assigned to MBOM through the summary logic of process route expansion. For example, 8500014-VV0101 (carriage assembly - already painted) is assigned YQ (paint)-ZP (assembly). For parts of the carriage undergoing welding production, the process routes are also reassigned, and all assembly routes become HZ (welding) and are transmitted to the SCF system. In practical applications, both MBOM and the SCF system have been verified, the expanded summary logic is feasible and can be applied to the production interface, and the SCF system can arrange the carriage production plan according to the expanded BOM data.

[0063] The MBOM process route summary logic can be as follows: the assembly site of the automotive branch 8500016* is summarized under 8500014*; all parts with process routes (purchased parts, body panels, self-made parts) are summarized under the assembly site of the automotive branch 8500016*; self-made sub-assemblies are summarized under 8500016*, the same as self-made sub-assemblies under 5000016*.

[0064] Furthermore, in one embodiment, a hierarchical structure and part numbers are added to the BOM, and production line codes are simultaneously added to the SCF system, specifically including:

[0065] Add a hierarchical structure and part number of the first virtual part number and the second virtual part number to the BOM, and simultaneously add two production line codes to the SCF system (order plan), namely the painting delivery line and the welding VAN delivery line, to ensure that the parts plan of each level of the vehicle can be opened and smoothly transferred.

[0066] Previously, the carriage business only involved the production of complete carriages at the carriage factory. The chassis plan was matched with the carriage plan to complete the unloading work at the carriage factory. Based on the change in the process flow in this application, the side panel assembly and the rear panel assembly are sent to the new body welding line for welding after the carriage is produced (cross factory and cross production line). The production planning system of the carriage can also query the real-time production plans of the side panel assembly and the rear panel assembly corresponding to the carriage, realizing the real-time linkage between the carriage assembly plan and the side panel (rear panel) sub-assembly plan.

[0067] S4: MBOM identifies the vehicle development code identifier to keep the vehicle model unchanged during chassis number conversion and transmits data to SAP.

[0068] For vehicle reporting, for example, for regular light trucks, the EBOM only needs to publish the engineering data for model A. For model J, after the data for model A is published, the MBOM system automatically forms a "vehicle and Class II chassis comparison relationship" and transmits it to the relevant systems for Class II chassis **J (for light commercial vehicle production scheduling) and 85000* (for transfer and loading into the truck bed). The vehicle is only completed when both actions are completed.

[0069] Unlike light trucks, mini-trucks do not require unloading the cargo box when reporting production. Therefore, the completion of a light commercial vehicle is considered complete upon completion. For model A, the solution is that the chassis number and the vehicle number are both A, hence there is no J data. Problems exist: 1. Mini-trucks lack J model data; 2. Four vehicles have chassis numbers of J, and the data has already been transmitted, affecting the completion of the entire vehicle. To address this, in this invention, the MBOM identifies the model development code identifier to maintain the model number during chassis number conversion and transmits the data to SAP. Specifically, the MBOM identifies the current model's model development code identifier and model number suffix. During chassis number conversion, the current model's model number suffix remains unchanged, and the data is aggregated and transmitted to SAP according to the current model number suffix.

[0070] For example, for small truck flatbed trailer models, MBOM identifies models with the development code B91 as "V5" and the model number ending in "A" (indicating that a box needs to be packed) through the system backend. When the chassis number is converted, the vehicle model remains unchanged, and the aggregated data is transmitted to SAP as model A, without the need to publish EBOM data for model J separately.

[0071] For the special small truck box data construction and multi-system flow method of this application, based on the balance of cost and manufacturability, the processing technology route of the small truck box and the rules for R&D and manufacturing data construction are re-planned, and the transmission path between SCF and SAP is opened up. A unified small truck body assembly process was established, and digital technology was used to achieve smooth flow of BOM data, production plans, and work reporting. The data information flow was reconstructed and integrated based on a new body process route plan: 1. New virtual parts and body structure tree BOMs were introduced into the EBOM data, and different blocks were grouped; 2. The process route aggregation rules in the MBOM data were expanded, assigning process routes to parts at different structural levels according to the actual planned process routes and transmitting them to the SCF; 3. The SCF system can drive production plans and parts plans according to the existing vehicle system deployment rules. Due to the introduction of the body structure, two virtual body welding and body assembly production line codes were added to the SCF, and the body assembly plan and sub-assembly plans were linked and interconnected in real time; 4. Based on the changes in body structure and process routes, the previous SAP data transmission rules were broken, and the MBOM to SAP transmission rules were modified. The MBOM identifies the vehicle development code and vehicle tail number through the system backend, keeping the vehicle model unchanged during chassis number conversion, and transmitting data to SAP to ensure work reporting is completed.

[0072] The method for constructing and transferring special small truck compartment data across multiple systems in this application adopts a new process and data transfer scheme, which can save manufacturing costs for different truck compartment models, conserve energy and energy consumption, and at the same time streamline the data flow to ensure that all data flows automatically online, realize the integration of the digital platform, save manpower and material resources, and specially design data-adapted processes for special processes, reflecting a high degree of consistency between business and data, as well as a high level of data service to business.

[0080] The side and rear panel assembly is supplied with welding equipment, and the welding equipment is assembled into a whole box and then painted with BIW (Biological Welding).

[0081] The final assembly carriage is delivered after the accessories are assembled.

[0082] In this application, the EBOM re-plans and reassembles the structure of the cargo box in the product BOM structural data, constructing both pre-painted and post-painted cargo box assemblies. Specifically, the re-planning and reassembly of the cargo box structure includes:

[0083] For the current light truck model, a virtual structure of the cargo box is built in the BOM and assigned a virtual part number;

[0084] The welded parts of the carriage are grouped under the second virtual part number structure;

[0085] The virtual part number includes a first virtual part number and a second virtual part number. The first virtual part number indicates that the carriage assembly has been painted, and the second virtual part number indicates that the carriage assembly has not been painted.

[0087] Based on the summary logic of the process route extension, the process route of MBOM is assigned, and the first virtual part number is assigned a paint-assembly mark.

[0088] For the parts of the carriage that are being welded, the corresponding process route is assigned, and all assembly routes are converted into welding marks and transmitted to the SCF system.

[0089] In this application, a hierarchical structure and part numbers are added to the BOM, and production line codes are added synchronously in the SCF system, specifically including:

An additional module is added to drive the MBOM to expand and allocate process routes, add hierarchical structures and part numbers to the BOM, and simultaneously add production line codes to the SCF system. The execution module is used to drive MBOM to recognize the vehicle development code mark so as to keep the vehicle model unchanged when the chassis number is changed, and to pass the data to SAP. The entire container carrying the BIW (Branded Container Wrap) is manufactured via a VAN (Van) painting production line. The specific process flow includes: Before painting the cargo box, the floor plate of the cargo box is spot-welded to the BIW chassis, and the side and rear plate pre-painting assembly is completed in the welding workshop. The improved manufacturing process and procedures for the small truck body include, specifically, the improved process planning as follows: The carriage floor is a stamped part, produced in the stamping workshop and supplied for welding. The side and rear panel assembly is supplied with welding equipment, and the welding equipment is assembled into a whole box and then painted with BIW (Biological Welding). The final assembly carriage is delivered after accessories are assembled. Specifically, the EBOM re-plans and reassembles the structure of the cargo box in the product BOM structural data, constructing the pre-painted and post-painted cargo box assemblies. This re-planning and reassembly of the cargo box structure specifically includes: For the current light truck model, a virtual structure of the cargo box is built in the BOM and assigned a virtual part number; The welded parts of the carriage are grouped under the second virtual part number structure; The virtual part number includes a first virtual part number and a second virtual part number. The first virtual part number indicates that the carriage assembly has been painted, and the second virtual part number indicates that the carriage assembly has not been painted. The MBOM expands and allocates the process route, specifically including: Based on the summary logic of the process route extension, the process route of MBOM is assigned, and the first virtual part number is assigned a paint-assembly mark. For the parts of the carriage that are being welded, the corresponding process route is assigned, and all assembly routes are converted into welding marks and transmitted to the SCF system; Specifically, adding hierarchical structures and part numbers to the BOM and synchronously adding production line codes to the SCF system includes: Add a hierarchical structure and part number of the first virtual part number and the second virtual part number to the BOM, and simultaneously add two production line codes in the SCF system, namely the painting delivery line and the welding VAN delivery line. Specifically, the MBOM identifies the vehicle development code identifier to maintain the vehicle model during chassis number conversion and transmits data to SAP, including: MBOM identifies the vehicle development code and vehicle number suffix of the current vehicle model. When the chassis number is converted, the vehicle number suffix of the current vehicle model remains unchanged. The data is then aggregated and transmitted to SAP according to the current vehicle number suffix.
