Targeting Zero Overlook of Defects Down to 0.02 mm

Our Lulimo C automated visual inspection system can inspect rotational components in 7 seconds cycle time. Manual inspections of these components are often affected by operator skill levels.

Automated visual inspection system for rotational components

Lulimo C

  • Our proprietary All Angle Multi Shot system enables complete inspection for microscopic defects in a cycle time of just 7 seconds with zero overlook.

  • An integrated transfer system allows continuous high-speed processing of components from loading to inspection and finally unloading.

  • Surface irregularities of lubricant or bonderizing marks are removed by our proprietary image processing, enabling to reduce excess detection.

Examples of targeted components

Defects detectable with a depth of
0.02 mm or more

Issues including ironing marks, scrubbing marks, dents, pits, underfills, die attributable defects and surface roughness/unevenness with a depth of 0.02 mm or more can all be detected at high speed on rotational components.

Vertical scratch
Horizontal scratch
Surface roughness

Advantages of introduction

Solve labor shortage

Prevent overlook

Reduce excess detection

Improve quality & reliability



All inspection processes are performed automatically inside the system.



Registration of master images

Master images of approved components can be created in just a few minutes. Comparison with these masters enables even components with large tolerances to be inspected with great accuracy.





We are able to design automatic loaders that can handle a wide range of components as optional units.




Components loaded into the system are automatically transferred to the prealignment unit. Correction of the rotational axis is then executed to improve inspection accuracy.




After prealignment, components are automatically transferred to the inspection unit. This unit is equipped with 7 line cameras that are used to capture images for inspection. The images are then compared with the masters using our proprietary image processing technologies, enabling the detection of defects.



Separation and unloading

Once inspection is completed, accepted and rejected components are judged and sent to their respective unloaders for discharge.
