Design Of Power Battery Module Automation Equipment And System

In the assembly and manufacturing process of automotive power battery module,it is necessary to strictly control the size,performance index,stability and safety of the module to ensure that the power battery system can run stably in the operating environment of the automobile.At present,in major factories,the above indicators of power battery modules and assembly production can not be completed by manual measurement or fixture production.The development of a power battery module automation equipment has become an important engineering problem to be solved urgently in automotive power battery system enterprises.In this paper,after fully understanding and discussing the composition and characteristics of the power battery module,this paper analyzes the structure of the soft package power battery,the cylindrical power battery and the square aluminum shell power battery,and chooses the assembly process of the 21700 cylindrical power battery module to design the automatic equipment system.Firstly,the composition and technological process of 21700 cylindrical power battery module are summarized.The main technologies include battery treatment,module assembly and final module assembly.The core processing section includes OCV test and core sorting.Module assembly includes plug-in core,side board and PC chip installation,upper and lower bracket installation,upper and lower bracket UV curing,point AB glue,assembly manifold and circuit board,AB glue pressure curing,laser cleaning,aluminum wire welding.Final module assembly,including module stacking,module EOL testing,module box and component installation,communication testing,pressure and airtightness testing.Then,after fully understanding the product structure and its characteristics,the production and assembly process is combed and the module assembly hardware is designed.In the battery processing section,artificial feeding is used,and the high precision HIOKI tester is used to test the performance of the battery,and the battery is sorted according to the test results.In the module assembly section,the collector and four-axis robot are used to insert the core into the bracket,and then the six-axis robot is used to cooperate with a series of equipment to complete the side board,cold water pipe,spot UV glue,UV curing,spot AB glue assembly manifold and collector circuit board,AB glue pressure-holding curing,laser cleaning,aluminum wire welding and other processes.In the final module assembly section,the modules are stacked and tested by EOL.Then the modules are loaded into the box and installed.Finally,the cabinet is tested for communication pressure and air tightness,and the upper cover is installed to complete the assembly and test of the whole module.Then,the software of the system is designed,and the high-precision intelligent scanning code is effectively used to bind the product's two-dimensional code and run through the whole system,and bind the test data,sensing data and machine data to ensure the effective traceability of the product.Finally,this paper has carried on the software and hardware debugging and verification of the data fusion system,through information,physical mass customization manufacturing system,highly flexible,as the power battery module,high flexibility,large-scale mass production to conduct a comprehensive exploration and verification.The automation equipment of the whole power battery module has been completed successfully,and all the planning and design of the system have been realized.
