3D Inspection

2D Profilers can measure width, height, and volume of sealant beads inline, regardless of surface finish or color.

Unlike triangulation sensors, interferometers can measure small parts in confined spaces without blind spots or unstable data.

Measure small part dimensions inline with pattern projection measurement heads. Projection from both sides reduces dead zones.

Detect burrs arising on terminals after electrode slitting. With ultra-high-resolution 3200 points/profile measurement, the LJ-X8000 Series produces stable detection even for minute burrs.

Profile measurement can be continuously performed on captured 3D shapes. This allows pass/fail criteria to be applied to maximum and minimum values over an area or period of time, making it possible to catch small defects in continuous processes.

Free-form planes allow the system to pick up on deviations from the typical contour of a surface.This makes stable defect detection possible, even for targets with complex shapes.

Highly accurate measurements can be made even when measuring targets with height differences or where the distance from the target to the camera could vary.

Detect chipping or dents in laser welded beads using 3D laser profilers. The measurement is unaffected by color or gloss of the weld, making inspection results stable through glare or bead shape variation.

Targets with multiple materials can be captured in a single profile, allowing measurements to be made between glass and metal surfaces. The LJ-X Series is equipped to handle reflectances ten times higher than conventional products.

For targets with different diameters, conventional vision systems often have a hard time focusing on the larger and smaller diameter areas at the same time. Measuring the height of the dents with a laser profiler makes it possible to inspect the whole surface at once.

3D inspection allows users to accurately detect whether components are properly seated in the assembly or if elements are tilted. Using a KEYENCE 2D/3D laser profiler with a blue laser ensures stable measurement, even for targets with varying materials.

A displacement sensor with an extremely small beam spot of just 3.5 µm can be used for accurate profile measurements of roughness and subtle shapes. 3D shape measurements are also possible through detailed scanning synchronized with the X-Y stage. Measurements with impressive angle characteristics are possible not only for opaque targets but also transparent targets and 3D shapes with mirrored surfaces.

The laser profiler's wide field of view makes it possible to inspect multiple targets traveling on a conveyor belt together. 3D position correction can be used to identify and inspect each cookie within the measurement range, enabling accurate sorting to improve quality and eliminate waste.
