Study On The Design Of Automatic Production Lines And Flexible Production Scheduling For Bioreagent Cards

The Biological reagent card is a kind of canister container containing liquid reagents,which is commonly used in laboratories,hospitals,and other places.Reagent cards are filled with different reagents and different doses,forming many types of reagent cards.At the present stage,the production of biological reagent cards is mainly done through workers operating the equipment,which is inefficient.Therefore,this paper designs a fully automatic filling production line for biological reagent cards,which can realize the processes of card feeding,filling,heat sealing,cooling,cutting,and card receiving of reagent cards.It also proposes a multi-product mixed production solution for the diversity of reagent types of biological reagent cards,which solves the production sequence with a scheduling algorithm so that the production line can complete the multi-product production task in a shorter time.The main work of this paper is as follows.1.The production process of filling biological reagent cards is modularised according to its design,which is divided into card feeding module,filling module,heat sealing module,cooling and cutting module,and card receiving module in turn,and then the 3D modeling design of each production module is completed using Solidworks,while the layout of the production line is completed linearly according to the production process.2.To address the problem of film deformation on the surface of the reagent card package during the production process,the main factors for film deformation were analyzed through simulation.The thermal unit module of ANSYS was used to simulate the thermal encapsulation process of biological reagent cards,and the deformation of the film was obtained by taking the heat sealing temperature and the heat sealing time as variables.Then the fuzzy PID algorithm is used to control the temperature to achieve a fast response to the temperature change,and the simulation results show that the fuzzy PID algorithm has a better control effect than the traditional PID.3.To address the problem of idle time of equipment due to the different processing times of each process in reagent card production,a mixed production scheduling method is proposed to reduce the idle time of equipment.It is verified that the improved genetic algorithm can find a better solution and the larger the size of the solution scheduling,the shorter the time required to complete the production when producing the same batch of products;finally,the reagent card filling production scheduling is optimized by combining the variable neighborhood search algorithm with the improved genetic algorithm.The algorithm is used in the production of biological reagent cards,and the results show that the use of the production scheduling algorithm can significantly improve the efficiency of production.
