Development of flexible positioning system for assembly line of body-in-white

摘要

A new flexible positioning system is developed to fulfill the mixed model production in a car body in white (BIW) welding production line, which is able to respond quickly market needs and shorten the cycle time of auto model update and improve productivity. The system architecture is researched and developed, and the execution unit and motion control unit is discussed. System motion control is realized by means of industrial Ethernet network and SERCOS communication protocol.
