Introducing Optoband:

Advanced Quality Control for Flat Metal Components

Optoband presents a sophisticated yet straightforward solution for inspecting bearing rings, flanges, and lamellae. Our system is designed to ensure each part meets strict quality standards for surface, dimensions, and flatness.

Operating at speeds up to 1000 mm/s and maximum part size up to 250mm, Optoband efficiently scans parts moving on a belt conveyor. The inspection process includes two consecutive stations, each equipped with similar camera configurations. Between these stations, a flipping mechanism ensures both sides of each part are thoroughly inspected, maintaining the flow of production without delay. 

Post-inspection, Optoband sorts parts into multiple categories based on the type of detected defects, either surface or dimensional, streamlining the process of identifying and addressing imperfections. Only OK parts continue to following operations. 

Optoband can also be configured to inspect vertically pressed parts for cracks and other mechanical damages. This adaptability makes Optoband an invaluable tool in maintaining the highest standards of quality in manufacturing assembly processes.

Typical Optoband installations has following main components:
  • Input of part
  • Inspection Station 1 
  • Flipping conveyor 
  • Inspection Station 2 
  • Output sorting conveyor 
  • Control cabinet

HIM and visualization
screens are installed either on the control cabinet, or on one of the inspection stations. Connection to previous and following operations is easily done through other conveyor systems.
