Design And Research Of Flexible Automation Production Line For Biological Detection Card

The biometric card is a column agglutination detection card,which is mainly used for blood type detection and auxiliary diagnosis of diseases.With the development of diagnostic technology and the increasing demand for individualization,enterprises are required to produce various types of biometric cards.Since the traditional assembly line cannot meet the requirements of making multi-variety and small batch productions,new assembly lines need to be designed.Using modular designs,the flexible automatic production line of biometric card selects different production modules to form production lines according to production requirements.Mixed flow production is realized through production scheduling,which enables the production line to complete the production tasks of multiple varieties and small batches in a short time.Firstly,according to the production technology and production characteristics of biological detection card the overall plan was determined,and according to the modular design theory,the flexible automatic production line is divided into different production modules,such as automatic card sending module,filling module,powder filling module and the packaging module.Based on modular design theory and the variation design theory,the mechanical structure of each module is designed.Secondly,the hardware system of flexible automatic production line of biological detection card is designed and the relevant components are selected.Then,the software system of the flexible automatic production line of the biometric card is designed.According to the technological process flow draw a program flow chart and using the sequential control method to write the program of the production unit.Finally,the mathematical model of production scheduling for flexible automated production lines is established.The improved genetic algorithm(IGA)is used to solve the production scheduling problem,and the design process of the improved genetic algorithm is introduced.In order to improve the solving ability of the improved genetic algorithm,the improved genetic algorithm and the variable neighborhood search algorithm are combined to obtain the improved genetic algorithm and the variable neighborhood hybrid algorithm(IGA-VNS).Numerical simulation experiments show that IGA-VNS can obtain a better solution than IGA.The application of IGA-VNS in the production scheduling of Bio-Detection card shows that the production efficiency of Bio-Detection card can be significantly improved.
