Three-dimensional dynamic control system and method for cross-platform mixed-flow production

Abstract

The invention discloses a three-dimensional dynamic control system and a method for cross-platform mixed-flow production. The system comprises an order production plan input module (1), a system operation module (2), a vehicle type process data input module (3), an equipment operation data input module (4), a data operation module (5) and a schedule output module (6). The output ends of the orderproduction plan input module, the vehicle type process data input module and the equipment operation data input module are connected with the input end of the system operation module. The output end of the system operation module is connected with the input end of the data operation module. The output end of the data operation module is connected with the input end of the schedule output module. The system operation module is externally connected with a vehicle manufacturing execution system. According to the three-dimensional dynamic control system and the method for cross-platform mixed-flowproduction, the mixed-line production time of different platform vehicle types can be controlled and the personnel workload at different moments can be balanced, the phenomenon of uneven idleness iseffectively improved, the conveying waiting waste of the line edge material grabbing equipment is avoided, the bottleneck work time is reduced, and the production efficiency of the production personnel and equipment are greatly improved.

Description

technical field [0001] The invention relates to an automobile manufacturing equipment and a production control method thereof, in particular to a three-dimensional dynamic control system and method for cross-platform mixed-flow production.

[0002] For automobile manufacturers, the needs of customers are diversified and personalized, and the product types and configuration requirements are more abundant. Considering the optimal use of enterprise resources, the mixed production of cross-platform and multi-variety models has become the mainstream method of current automobile manufacturing scheduling. Waste of resources caused by differences Relying on traditional manual experience scheduling and simple model matching scheduling methods can no longer meet the needs of cross-platform multi-variety mixed flow balance. The main reasons are as follows:

[0003] 1. Different from ordinary passenger car companies, in the assembly workshop of a certain car company, nearly a hundred models of multiple platforms are currently in mixed production. The process operation of the same model used in each station is fixed, resulting in the balance of any model cannot effectively balance the difference in working hours of each model, resulting in low efficiency of on-site personnel

[0004] 2. On the other hand, because fixed equipment such as the material grabbing robot arm of the production line cannot accept the production model scheduling input and demand time, they only wait for the model to be in place, and manually operate the robot arm to pick up materials and assemble materials, resulting in a large number of equipment The time is in a waiting state, and the working hours of picking and assembling work for different models are different. There are too many idles during the use of equipment, and the waiting results in low equipment utilization, and the initial position setting is single. For the assembly of models with too long working hours The process is easy to cause collision and interference, which greatly affects the utilization rate of equipment resources, causes a great waste of production capacity, brings production quality risks, and brings incalculable cost losses to the enterprise
