The Smart Identification of Bolt Assembly System is equipped with intelligent 3D imaging technology and advanced AI algorithm, which can detect three-dimensional information through non-contact, single-lens, and single-shot methods accurately by >30fps recognition rate. The system significantly enhance the capacity of identification, positioning and guidance in production line, which reduces the quality risk caused by missing bolts and mistaked assembly widely existing in industrial manufacturing. It can be widely used in different bolt assembly lines of such as vehicle assembly and equipment assembly.
