Design and implementation of error proofing system for tightening power battery bolts
Power batteries are usually fixed in the battery box by bolts.Due to the small installation space,some bolts still need to be manually assembled,which inevitably leads to quality problems such as bolt omission,over tightening,and failure to follow the assembly process sequence.Therefore,a bolt er-ror proofing tightening method to address the above issues was proposed.By combining ultrasonic positio-ning system with electric tightening system,the torque and position of bolt installation process are moni-tored in real-time.The sequence of bolt installation positions is controlled through software,and the correctness of the installation process is reminded through sound and light methods.Explain the princi-ples,methods,development,error analysis,and correction of error proofing systems.The experimental results show that the first pass rate of error proofing reaches 100％,which meets the needs of manual as-sembly operations.
