Project Details

Problem Statement: The customer required an automated machine that could load, unload, and quarantine out-of-spec roller bearings. Inspection focused on the inner cage of roller bearings ranging from 30mm to 150mm OD. The inspection criteria required 3D laser inspection of both sides of the bearing and controlled rotation to scan the entire cage. The cycle rate was proven at less than 6 seconds per piece, with the following defects detected:

  • Cage rivet presence
  • Cage rivet height
  • Missing ball
  • Double cage

Automation Equipment

  • Keyence LJV-7080 3D laser
  • Four-position rotary index dial with quick-change tooling
  • Servo motor and pneumatically engaged spindle for controlled turning of the bearings
  • Siemens controls
  • Lockable reject bin with Poke Yoke features
  • Load and unload mechanism for interface with the customer-supplied Flexlink-style conveyor

Machine Performance

  • Capacity Requirement: Less than 6 seconds per piece
  • Bearing Diameter Range: 30mm – 150mm
  • Poke Yoke Features: Locked reject drawer with sensor detection
  • Expected Utilization Rate: 24 hours / 7 days
  • Equipment Availability: Greater than 85%
