Outline
To address the requirements for flexible transportation and precise assembly of multi-size battery packs of new energy vehicles during the final assembly process, a flexible transfer solution for battery packs based on a double-layer roller bed conveyor system has been researched and developed. This solution adopts a skid design with adjustable limiting blocks, and combines a T-type transfer machine, automated guided vehicles, and an overhead buffer system to establish a full-process conveying system covering battery pack loading, buffering, offline assembly, and empty skid return. By integrating Radio Frequency Identification technology and a Manufacturing Execution System through a PLC control system, accurate synchronization between battery pack information tracking and production queues is achieved. Implementation results show that the system can realize overhead buffering of 40 battery packs, improve the workshop space utilization rate by more than 30%, and achieve a battery pack loading accuracy rate of 99.5%. It can ensure continuous supply for 40 min under a production rhythm of 60 JPH (Jobs Per Hour). This conveying solution provides effective technical support for the mixed-model production of new energy vehicles.
