Description

Technical Field

[0001] The present application relates to the technical field of vehicle production and manufacturing, and specifically to a method, device and equipment for constructing data of a special pickup truck compartment and circulating data in multiple systems. Background Art

[0002] For the conventional process of light truck body engineering and packing: the body is a separate assembly, and the chassis front engineering is completed and then transferred to the body for delivery after the body assembly is completed; for the light truck manufacturing process planning: the body floor is a stamping part, which is produced in the stamping workshop and supplied for welding. The body floor is connected to the frame and is equipped with BIW (body in white) for joint painting. The side and rear panels are rolled and welded and painted in the body operation department, and then supplied to the general assembly workshop, and finally the general assembly workshop completes the body assembly and delivers it.

[0003] Due to the particularity of the light truck process, the in-carriage manufacturing target set has been exceeded but not reached compared to the PD target (referring to achieving project success through detailed project planning, project control and teamwork). After data synchronization engineering analysis and benchmarking the manufacturing process of light trucks and micro truck series of competing products in the industry, the manufacturing cost target must reach the PD target and control the in-carriage manufacturing cost within the limit. Through analysis to reduce the cost of the entire value chain of car manufacturing, the strategy of loading the entire box with BIW through the second painting line is analyzed as one of the most important directions, with the aim of reducing the kinetic energy of the separate painting of the side and rear panel assembly and the consumption of process logistics.

[0041] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0043] In a first aspect, an embodiment of the present application provides a method for constructing and transferring data of a special pickup truck compartment and multiple systems.

[0044] In one embodiment, referring to Figure 1 , Figure 1 This is a flowchart of the special truck compartment data construction and multi-system flow method of this application. Figure 1 As shown, the special truck compartment data construction and multi-system circulation method includes:

[0045] S1: The whole box of BIW passes the VAN car painting production line, and improves the manufacturing process and process of the small truck compartment; VAN car, also known as a van or a small passenger van, is a car mainly used for carrying cargo and transporting multiple people.

[0046] In this application, the whole box loaded with BIW passes through the VAN vehicle painting production line, wherein, as for the process flow, it specifically includes: carrying out the pre-painting assembly of the vehicle body, spot welding the vehicle body floor to the BIW chassis, and completing the assembly of the side and rear panels before painting in the welding workshop.

[0047] In this application, the manufacturing process and process of the pickup truck compartment are improved, wherein the improved process planning specifically includes:

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

[0049] S102: The side and rear panel assembly (before painting) is supplied to welding, and the whole box of welding and assembly is loaded with BIW for painting;

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

[0051] S2: EBOM re-plans and builds the structure of the carriage in the product BOM structure data, and constructs the carriage assembly before and after painting;

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

[0053] Furthermore, in one embodiment, the EBOM re-plans and builds the structure of the carriage in the product BOM structure data, and constructs the carriage assembly after and before painting, wherein the re-planning and building of the carriage structure specifically includes:

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

[0055] S202: Grouping the welding 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, EBOM re-plans and builds the structure of the car body in the product BOM structural data, and constructs the car body assembly before and after painting. For example, in the vehicle model V0D1-101-002A, a virtual structure of the car body is built in the BOM, and virtual part numbers 8500014-VV0101 (indicating car body assembly-painted) and 8500016-VV0101 (indicating car body assembly-unpainted) are assigned, and the car body welding parts are grouped under the 8500016-VV0101 structure, which fully reflects the process flow of sub-assembly welding, painting and assembly of the pickup truck car body.

[0058] S3: MBOM expands and allocates the process route, adds the hierarchy and part number in the BOM, and simultaneously adds the production line code in the SCF system;

[0059] Furthermore, in one embodiment, 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 the MBOM and assign a paint-assembly mark to the first virtual part number;

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

[0062] Specifically, MBOM expands and distributes the process route: In the implementation of car body parts manufacturing, the process route of MBOM is assigned through the extended summary logic of the process route. For example, 8500014-VV0101 (car body assembly-painted) is assigned YQ (paint)-ZP (assembly). For the parts of the car body in welding production, the process route is also reassigned, and all assembly routes become HZ (welding) and passed to the SCF system. In actual applications, both MBOM and SCF systems have been verified, and the extended summary logic is feasible and can be applied to the production interface. The SCF system can arrange the production plan of the car body according to the expanded BOM data.

[0063] For the MBOM process route summary logic, it can be: the automobile branch assembly site 8500016* is summarized under 8500014*; all parts with process routes (purchased parts, carriages, self-made parts) are summarized under 8500016* at the automobile branch assembly site; self-made sub-assembly parts are summarized under 8500016*, the same as 5000016* self-made sub-assembly parts.

[0064] Furthermore, in one embodiment, a hierarchy and part number are added to the BOM, and a production line code is added to the SCF system simultaneously, specifically including:

[0065] Add the hierarchical structure and part numbers of the first virtual part number and the second virtual part number in the BOM, and simultaneously add two production line codes in the SCF system (order plan), namely the painting delivery line and the welding VAN vehicle delivery line, to ensure that the part plans at all levels of the car body can be opened and transmitted smoothly.

[0066] Since the previous car body business only involved the production of whole boxes in the car body factory, the chassis plan matched the car body plan to complete the box unloading work in the car body factory. Based on the changes 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 car body is produced (across factories and production lines). The real-time production plans of the side panel assembly and the rear panel assembly corresponding to the car body can also be queried in the car body production planning system, realizing the real-time linkage of the car body assembly plan-the side panel (rear panel) sub-assembly plan.

[0067] S4: MBOM identifies the model development code mark to keep the model unchanged when the chassis number is converted and pass the data to SAP.

[0068] For the business problem of reporting the whole vehicle, for example, the EBOM of a conventional light truck only needs to publish the engineering data of model A. After the preparation data of model A is released, the MBOM system automatically forms a "comparison between the whole vehicle and the second-class chassis" and transmits it to the relevant system. The second-class chassis **J (for light commercial production) and 85000* (dumping and unloading of the car body) structure. The whole vehicle is completed only after both actions are completed.

[0069] Unlike light trucks, light trucks do not need to drop the box when reporting the production of the whole vehicle, so the light commercial vehicle is completed when the whole vehicle is completed. The solution for the completion of model A is that the chassis number is the same as the whole vehicle number A, so there is no J data; there are problems: 1. Light trucks have no J model data; 2. The chassis number of 4 vehicles is J, and the data has been transferred, which affects the completion of the whole vehicle. In view of this situation, in the present invention, MBOM identifies the model development code mark to keep the model unchanged when the chassis number is converted, and transfer data to SAP. Specifically, MBOM identifies the model development code mark and model tail number of the current model, and keeps the model tail number of the current model unchanged when the chassis number is converted, and summarizes the data and transfers it to SAP according to the current model tail number.

[0070] For example, for small truck flatbed models, MBOM uses the system background to identify the model development code B91 as "V5" and the model number suffix "A" (indicating that it needs to be packed). When the chassis number is converted, the vehicle model remains unchanged, and the summary data is transmitted to SAP according to the A model. There is no need to publish the J model EBOM data separately.

[0071] For the special pickup truck body data construction and multi-system circulation method of this application, based on the balance between cost and processability, the processing route and R&D and manufacturing data construction rules of the pickup truck body are replanned to open up the transmission path between SCF and SAP. A unified process flow for the assembly of pickup truck bodies has been established, and the smooth flow of BOM data flow, production plan and work report has been realized through digital technology; the data information flow under the new body process route planning has been reconstructed and connected: 1. New virtual parts and body structure tree BOM are introduced into EBOM data, and different blocks are grouped; 2. The collection rules of process routes are expanded in MBOM data, and process routes of parts at different structural levels are assigned according to the actual planned process routes and transmitted to SCF; 3. The SCF system can develop rules according to the existing vehicle system to drive production plans and parts plans. Due to the introduction of body structure, two production line codes for virtual body welding and body assembly are added to SCF, and the body assembly plan and sub-assembly plan are linked at the same time, which can be checked in real time; 4. Based on the changes in body structure and process route, the previous SAP data transmission rules are broken, and the MBOM to SAP transmission rules are modified. MBOM identifies the model development code mark and model tail number through the system background, keeps the model unchanged when the chassis number is converted, and transmits data to SAP to ensure that the work report is completed.

[0072] The special pickup truck compartment data construction and multi-system circulation method of the embodiment of the present application adopts a new process solution and data circulation solution, which can save the manufacturing cost of compartments of different models, save kinetic energy and consumption, and at the same time open up the data flow, ensure that all data flows automatically online, realize the integration of the digital platform, save manpower and material resources, and tailor-made data adaptation processes for special process flows, which embodies the high consistency of business and data, as well as the high level of data serving the business.

Figure 2 As shown, the special pickup truck compartment data construction and multi-system circulation device includes: an improvement module, a construction module, an addition module, and an execution module.

[0075] The improvement module is used to drive the whole box of BIW to pass the VAN car painting production line and improve the manufacturing process and process of the pickup truck body; the construction module is used to drive EBOM to re-plan and build the structure of the body in the product BOM structure data, and build the body assembly after and before painting; the addition module is used to drive MBOM to expand and allocate the process route, add the hierarchy and part number in the BOM, and simultaneously add the production line code in the SCF system; the execution module is used to drive MBOM to identify the model development code mark, so as to keep the model unchanged when the chassis number is converted, and pass the data to SAP.

[0076] In this application, the whole box of BIW passes through the VAN car painting production line, among which, the process flow specifically includes:

[0077] Carry out the car body pre-painting assembly, spot weld the car body floor to the BIW chassis, and complete the assembly of the side and rear panels before painting in the welding workshop.

[0080] The side and rear panel assembly is supplied for welding, and the whole box of welding and assembly is loaded with BIW for painting;

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

[0083] For the current light truck models, a virtual structure of the vehicle compartment is built in the BOM and a virtual part number is assigned;

[0084] The welding 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.

[0088] For the parts of the carriage during welding production, the corresponding process routes are assigned, and the entire assembly route is converted into welding marks and transmitted to the SCF system.
