Abstract: The article studied the design method of integrating finished industrial robots into intelligent manufacturing production lines as workstations and designed a packaging system based on KUKA six-axis industrial robots for the intelligent manufacturing production line of cultural and creative pen holders. The system used industrial robots as the core equipment，paired with PLC，sensing components，etc. ，to jointly complete the commercial packaging of pen holder products. The structural composition，operation process，control mode，and program framework of the KUKA robot in the packaging system could be widely applied to developing packaging automation systems on production lines. In addition，the study effectively solved the interference problem of low-stiffness packaging boxes， increased the success rate of packaging from 50% to 96%，and did not change the packaging type or increase packaging costs. It has good reference value for similar packaging operations.

Key words: industrial robots, PLC；control mode, signal perception, process flow
