[0116] Figure 2 is a flow chart of a vehicle assembly method provided by one or more embodiments of the present invention.

[0117] like Figure 2 The vehicle assembly method shown is based on a vehicle assembly process system, and the vehicle assembly method includes: a production preparation step A1 and a block BOP compilation step A2;

[0118] The production preparation step A1 includes the steps of maintaining process resources, building a factory structure tree, maintaining process knowledge, and maintaining a material library.

[0119] Step A2 of compiling block BOP includes the steps of generating process task orders, compiling tasks, compiling processes, reviewing processes, synchronizing process data, adjusting procedures, maintaining parameters, and supporting materials.

[0120] Specifically, in the step of maintaining process resources, resource management specialists maintain the process resource library, which includes confirming process resources such as equipment, tools, jigs, measuring tools, etc. through database data, and also includes on-site sampling of data on process resources such as equipment, tools, jigs, measuring tools, etc. to ensure the completeness of process resources.

[0121] In the step of building a factory structure tree, the process engineer builds the factory structure tree based on the factory, including factories, workshops, production lines, workstations, process resources, etc., that is, the production capacity and production capacity characteristics of each factory are mapped in the vehicle assembly process system.

[0122] In the step of maintaining process knowledge, the resource management specialist maintains the process knowledge base, including process knowledge such as product characteristics and process characteristics, that is, a process knowledge base based on the production capacity and production capacity characteristics of the factory; if it is found that the factory cannot complete the process knowledge required for the current product, other factories are screened based on the process knowledge, and information on transferring or starting other factory processes is proposed.

[0123] In the step of maintaining the material library, the resource management specialist maintains the material library, including oils, adhesives and sealing materials, etc.; that is, the production capacity and production capacity characteristics of the supporting factories and the process knowledge base required for the current products, and prepares the corresponding consumables, etc.

[0124] After all the steps in the production preparation process are completed, a process approval notice will be generated.

[0125] In the step of generating a process task list, the vehicle assembly process system automatically filters and parses the production tasks of multiple models based on the process standard notice to generate a block process task list shared by multiple models, including new and changed tasks.

[0126] During the task preparation step, the process engineer can view and review the block process task sheet in the vehicle assembly process system to clarify the process preparation tasks.

[0127] In the process preparation step, the process engineer can prepare the block BOP, including query, process route information, block-block BOP-production line association information, process creation information, associated workstation information, material allocation information and process resource information, and feature addition information, so as to define working hours, tightening torque and other tasks.

[0128] In the process review step, after the block BOP is completed, the process engineer initiates the review process, and the system automatically generates process documents. The process supervisor can review the block process tasks. After the review is passed, the process resource opening authority is realized and production is started.

[0129] In the process data synchronization step, the process operator automatically synchronizes the process under the block BOP to the platform BOP through the function in the vehicle assembly process system.

[0130] During the process adjustment step, the technician will further adjust the platform BOP sequence, that is, make necessary adjustments to the sequence of processes that are automatically synchronized to the platform BOP. It is possible that there is a deviation between the actual process environment and the data record, and fine-tuning can be done within the allowable range to better adapt to actual production requirements.

[0131] In the parameter maintenance step, the process technician performs single-vehicle filling parameter maintenance and performs semi-automatic maintenance on the planned single vehicle on the maintenance panel of the vehicle assembly process system. That is, the vehicle assembly process system automatically maintains one part and manually maintains the other part according to the preset division of labor rules.

[0132] In the material support step, the vehicle assembly process system transmits process master data to the MOM and ERP systems, thereby supporting downstream production operations.

[0133] In this embodiment, it also includes:

[0134] Taking Block BOP as the unit, carry out the steps of compiling Block BOP;

[0135] The production preparation steps are carried out based on the association between the block BOP and the production line.

[0136] Specifically, in this embodiment, the so-called basic modules that constitute the vehicle platform and can be used in multiple vehicle platforms are deconstructed, and process design is carried out based on the blocks. The blocks are associated with the production lines, and each block is produced on a different production line. Based on the above scheme, the information associated with the blocks and the production lines is compiled into different block BOPs.

[0137] The platform BOP can be built as a factory unit, and the processes of all block BOPs under the factory production line can be gathered according to the workstation rules. The platform BOP is used as the factory's process master data, and finally the single vehicle process data can be extracted according to the order requirements. Corresponding to the single vehicle process data, it can be realized on the same production line to meet the production requirements of multiple varieties, small batches, and customization.

[0138] In this embodiment, the impact of local vehicle personalization requirements on the entire production line is reduced, and rapid identification and response to product changes can be achieved, which is highly consistent with the multi-variety, small batch, customized production model.

[0139] In this embodiment, a modular process design is adopted to deduplicate the compilation tasks of the vehicle model process, which greatly reduces the process compilation tasks, improves the reusability of the modular process, and improves the efficiency of process compilation.

[0140] In this embodiment, the process preparation is transformed from production-pull type to forward process preparation synchronized with product development, and the process design work is carried out in advance, effectively shortening the process preparation time.

[0141] In this embodiment, a set of process data is generated for each single vehicle to achieve accurate control of the single vehicle, improve product manufacturing quality, and ensure the continuous flow of the production line.

[0142] Figure 3 is a structural diagram of a vehicle assembly device provided by one or more embodiments of the present invention.

[0143] like Figure 3 The vehicle assembly device shown includes: a production preparation module and a compilation block BOP module;

[0144] Production preparation module, used to maintain process resources, build factory structure tree, maintain process knowledge and maintain material library;

[0145] The compilation block BOP module is used to generate process task orders, compile tasks, process compilation, process review, process data synchronization, process adjustment, parameter maintenance and material support.

[0146] It is worth noting that although the system only discloses the production preparation module and the compilation block BOP module, it does not mean that the device is limited to the above-mentioned basic functional modules. Rather, what the present invention wants to express is that, based on the above-mentioned basic functional modules, those skilled in the art can arbitrarily add one or more functional modules in combination with the prior art to form an infinite number of embodiments or technical solutions. In other words, the system is open rather than closed. Just because the present embodiment only discloses individual basic functional modules, it cannot be considered that the scope of protection of the claims of the present invention is limited to the above-mentioned basic functional modules.

[0147] Through the above scheme, the following beneficial technical effects are obtained:

[0148] This application carries out process design by taking blocks as units. Blocks are associated with production lines. Each block is produced on different production lines, so that different block BOPs can be compiled, so that the production process can better cope with complex production needs.

[0149] This application builds a platform BOP in each factory, aggregates the processes from all blocks under the factory's production line according to the workstation rules, realizes the platform BOP as the factory's process master data, and extracts single-vehicle process data according to order requirements.

[0150] The modular block BOP compilation concept of this application greatly reduces the process compilation tasks by deduplicating the compilation tasks of the vehicle model process, improves the reusability of the modular process, and improves the efficiency of process compilation.

[0151] This application constructs a master process data source for factory production by forming a platform BOP from a block BOP, and can form a set of process data for each single vehicle, thereby achieving accurate control of the single vehicle and improving product manufacturing quality.

[0152] This application synchronizes the preparation time of modular block BOP with product development, advances process design work, and effectively shortens process preparation time.
