Travelling crane pre-judging, scheduling and controlling method for electroplating production line

Abstract

The invention discloses a travelling crane pre-judging, scheduling and controlling method for an electroplating production line. The method comprises the steps that a process flow diagram is compiled according to each process requirement; a unique procedure code is distributed to each procedure according to the process flow diagram; a complete control sequence of each process product is calculated and generated; whether each process product conflicts with an on-line product during on-line production or not is judged; products capable of being subjected to an on-line production process are locked, the complete control sequences of the products are updated to an execution area, and the transporting task of the takt is executed according to the control sequences; scheduling and transporting of the takt are executed, meanwhile, the production task of the next takt is prepared, and transporting of the next takt is directly started after the scheduling and transporting task of the takt is executed; and a travelling crane executes carrying tasks according to the process paths and process time of all the products, and the products are carried to procedures specified by the control sequences to complete the transporting task of the takt. According to the method, multiple process products can be produced in a mixed manner at the same time, the production efficiency is improved, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to the field of traffic scheduling control of an electroplating production line, in particular to a predictive dispatch control method for electroplating production line traffic. Background technique [0002] Electroplating production belongs to process control, which requires that the sequence of different processes of the same process cannot be changed, and the processing time of each process and the time interval of different processes must not exceed the range of process requirements, otherwise it will not meet the production process and cause the product to be scrapped. In general, an electroplating production line can process products of several different processes, but it will be very difficult for the traffic dispatching control system to ensure that the processing time of different processes of all process products on the production line is within the allowable range of the process. At present, the scheduling method of fi...

[0002] Electroplating production belongs to process control, which requires that the sequence of different processes of the same process cannot be changed, and the processing time of each process and the time interval of different processes must not exceed the range of process requirements, otherwise it will not meet the production process and cause the product to be scrapped

In general, an electroplating production line can process products of several different processes, but it will be very difficult for the traffic scheduling control system to ensure that the processing time of different processes of all processes on the production line is within the allowable range of the process

At present, the scheduling method of fixed driving schedule and cycle cycle is adopted, but this method can only produce one kind of craft product at the same time. For multi-batch and small-batch products with different production processes, it is necessary to complete the production of a kind of craft products. After that, shut down and switch the production mode of another process product, not only the efficiency is too low, but also the product quality cannot be guaranteed
