In the field of mechanical equipment manufacturing, the sealing ring on the joint is a key sealing component, and its assembly quality directly affects the safety and reliability of the equipment. Therefore, the automatic assembly technology of the sealing ring came into being and became a research hotspot in the field of industrial manufacturing.
