A method for managing and controlling an empty card and a computer-readable medium

Abstract

The invention discloses an empty card management and control method and a computer-readable medium. At a first set interval, the number and priority of empty cards for each storage area included in the production plant is calculated, so as to determine the storage level quantity control limit of each storage area according to the empty card quantity demand of each storage area and the required empty card type, and when the number of empty cards of the storage area reaches the corresponding storage level quantity control limit, the empty cards of the required type are directly obtained from thestorage area with low priority. According to the currently determined priority level, when there is a demand for a free card, the balance movement of the empty stuck in the production plant is driven. The invention solves the problem of congestion and ensures the smoothness of logistics transportation, maximizes the storage space of each storage area in the production plant, effectively ensures the demand quantity of empty cards in each storage area, minimizes the occurrence of empty card secondary transportation, is conducive to the improvement of equipment crop mobility rate and transportation resource utilization rate, and reduces the equipment idle time.

Description

technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to a method for managing and controlling an empty card and a computer-readable medium. Background technique [0002] In the display panel manufacturing process, it is necessary to use card slots to transport substrates between various manufacturing equipment in the production plant (Cell), and after completing the production of different types of substrates in the production factory, it is necessary to use card slots to transport the substrates to modules The factory (Module) performs assembly and other processes, and then returns the blank cards (that is, the card case without any substrate) applicable to different models to the production factory for subsequent production. The following problems are likely to occur during the handling of empty cards: [0003] 1. In the actual operation process of the production plant, due to the long distance of empty card trans...

AI Technical Summary

Problems solved by technology

[0003] 1. In the actual operation process of the production plant, due to the long transport distance of the empty card, the resource occupation and the reduction of transport efficiency caused by the problem

[0004] 2. Due to the different product structures of the Cell factory and the different demands for empty cards, the empty card type without demand occupies storage resources, or the empty card with demand cannot be accurately moved to the corresponding location

[0005] 3. In the case of a lot of storage space and a single logistics path, the location of the empty card to be transported is not accurate, resulting in waste of secondary transport, or problems such as reverse logistics
