Research On Intelligent Assembly Technology Of Fire Valve

Fires have been one of the frequent disasters in recent years.As far as 2020,a total of252,000 fires have been reported nationwide,with 1,183 deaths and 775 injuries caused by fires,resulting in a property loss of 4.009 billion yuan.The number of reports received has decreased,but the impact of the fire cannot be underestimated.Fire fighting has become a relief medicine in the event of a fire,which can limit the occurrence of fires.The fire extinguisher is the main method of extinguishing fires,and the fire valve is the key component of the fire extinguisher.The fire valve is assembled from eight parts.The traditional assembly method of fire valve is mainly completed by manual assembly.This assembly method not only wastes human resources,but also cannot well identify valve body defects through visual observation during the assembly process,causing hidden product quality hazards.This article aims at the problems of high work intensity and insufficient defect identification in the assembly process of most fire valves at home and abroad.Under the premise of ensuring the safety,feasibility and adaptability of the equipment,the intelligent assembly equipment for fire valves is carried out.Design and research.The specific content is as follows:First,the overall design of the fire valve intelligent assembly equipment is outlined,the necessity and feasibility of the fire valve intelligent assembly equipment in the assembly process of fire equipment are outlined,and the domestic and foreign automation technology,fire protection electrical and valve body recognition defect algorithms are analyzed.Insufficient and lessons to be learned.Conceive the work flow of the intelligent assembly equipment of fire valve in the process of automatic transportation and assembly,divide each station module,and design a plan that can meet the requirements of the intelligent assembly equipment of fire valve as a whole and each functional module.Secondly,the mechanical structure of the intelligent assembly equipment for fire valves is designed.According to the analysis and design of the overall functional requirements and schemes of the fire valve intelligent assembly equipment,the four parts of the automatic clamping device structure design of the fire valve intelligent assembly equipment,the support bearing capacity planning,the vibrating plate structure design and the O-ring seal planning are analyzed and designed in detail.Design its mechanical structure.And on this basis,the key components are selected and analyzed.Third,analyze the control system of the fire valve intelligent assembly equipment,and introduce the software and hardware.On this basis,the control system is designed,the structure and function of the control system are determined,the assembly process is designed,and the hardware is selected.This chapter also introduces the design and development of the human-machine interface(HMI),the overall design and interface development,to ensure that the entire equipment can be completed smoothly.From time to time,the valve body defect recognition based on convolutional neural network is introduced,model design and experimental results are analyzed.Avoiding the traditional manual operation of valve body defect recognition,the convolutional neural network only needs to simply process the collected pictures to complete the valve body defect rate recognition,and the cross-layer convolutional neural network is added in the recognition process to increase the defect rate Recognition accuracy,which allows fire-fighting equipment to avoid quality problems in the automated equipment process.Finally,in order to ensure the feasibility of intelligent assembly equipment for fire valves,a feasibility system was developed and an information database was established through SQL SERVER 2003.The entire feasibility system mainly includes four modules: information management,information statistics,feasibility evaluation,and online users.It can display the information in the assembly process on an interface,which is convenient for future reference at any time,and is also useful for companies to use this automation equipment in the future.Assert the assessment.The fire-fighting valve intelligent assembly equipment designed in this paper meets the needs of the production and assembly process of fire-fighting valves,and addresses the problems of high labor costs,low manual operation safety,low valve body defect identification efficiency,and difficulty in operation in the current production and assembly process.The effective solution will greatly improve the production and assembly operation process of the fire valve body in the future.In addition,the intelligent assembly equipment for fire-fighting valves designed and developed in this project aims to achieve continuous and stable operation.Its innovation lies in:(1)Fully automated material fetching and delivery is used to complete automatic material fetching and delivery operations;(2)valve body defect identification is introduced,Ensure that the quality of the produced valve body meets the standard;(3)Introduce a feasibility system to record the number of materials used and the number of faults and defects every day to facilitate regular comparison and analysis,and to improve and optimize the equipment in time based on the data.
