| Since ancient times,military strength has always been an important guarantee for maintaining the political,economic and cultural development of a country.Now,the standard for measuring a country’s military strength is no longer a simple superposition of the number of garrison troops,and owning advanced weapons and equipment has become the goal pursued by all countries.Nowadays,military weapons are not only launching and detonating weapons.With the development of intelligence and informatization,weapons have also changed with the information revolution.With the development of intelligence and informatization,weapons have also changed with the information revolution.As a kind of disposable energy reserve,thermal battery has been widely used in artillery fuze due to its fast activation speed,long storage time,compact structure,high specific energy and specific power,low production cost and other advantages,thus thermal battery began to develop rapidly.With the expansion of the application scope of thermal battery and the increase of its usage,the traditional assembly method,namely manual assembly method,is difficult to meet the increasing supply demand because of its low efficiency.Therefore,based on the existing domestic assembly process,combined with the research on the manual assembly process of thermal battery,this dissertation designs a set of equipment that can realize the automatic assembly of thermal battery electric stack,artificial mica enclosure,and external ignition rod,to realize the automatic assembly of thermal battery,and improve the assembly precision and assembly efficiency.First of all,this dissertation introduces the development of thermal battery,and summarizes the technical difficulties of automatic assembly by understanding the research status at home and abroad,as well as the manual assembly process.According to the requirements of thermal battery assembly,the automatic assembly process plan is formulated,and the process design,structure design and control principle design are completed.Secondly,verify the feasibility of the design scheme.The dynamic analysis and impact load calculation of the wrapping mechanism are carried out,and the elastic deformation of the mica sheet wrapping is calculated and verified.The static analysis is carried out for the main components and components with large load.At the same time,in order to ensure the positioning accuracy and assembly reliability of the assembly mechanism,PLC is used as the control core of the assembly system,and the time delay module is used to control the system and make the system closed-loop through sensors.Finally,the system is debugged to complete the physical construction of the assembly system,adjust the layout of the assembly system and the motion parameters of each motion mechanism,and conduct experimental debugging for each assembly action in the assembly system.After debugging,the overall process assembly is carried out to obtain the system assembly efficiency and verify the assembly effect.The realization of automatic assembly of thermal batteries can fully release manpower,reduce human risk,reduce human damage,improve assembly accuracy and assembly efficiency,and then fill the gap that may appear in China’s demand for thermal batteries.It is of positive and important significance to China’s national defense industry and military field. |
