HALO uses a simple hang-by-the-head gravity track to feed parts through a series of inspection sensors; multiple cameras, lasers and eddy-current to provide 360o dimensional inspection, 360o visual defect detection, crack detection, heat-treatment verification and recess inspection/measurement all at inspection rates up to 400 parts per minute. No more complicated bowl feeder changeover, only a quick width adjustment for shank diameter. No dial plates, no conveyors, HALO has a simple, single point track adjustment providing the fastest changeover in the industry. HALO ensures defect free product with the most advanced (patent pending) feature measurement and defect detection capability.

The standard HALO inspection system is equipped with 4 cameras with 4 backlights and 2 surface illuminating lights (one from the top and one from the bottom) for 360o profile measurements and 360o visual defect detection. A patented light sequence process generates 8 images from 4 cameras.

The 4 backlit images provide 360o dimensional inspection to part print specifications. Easy to use, menu-driven software allows for fast set-up as each part feature is clearly defined print specifications entered, saved and recalled from memory.

In addition to the incomparable 360o dimensional measurement capabilities, HALO has a patented process of light sequencing. Milliseconds after backlighting the parts, front lights from above and below illuminate the parts surface to provide 360o surface inspection. This provides detection of thread nicks, knurl damage, coating inspection, thread patch analysis, dents, scratches and other surface defects.

Uniquely, the top front light is utilized by Gi’s Axial View lens to detect small cracks that are typically undetected by other inspection means; like standard vision or eddy-current. The bottom front light is utilized by a set of cameras to inspection the bearing surface for cracks and other visual defects. These defects cannot be detected by dial table sorting machines. A dedicated standard lens camera is used to measure recess and recess features and eddy-current can be added to detect the presence of heat-treatment.

The Gi-HALO sorting machine provides the ultimate inspection for bolts. Its’ unique, simplified part handling lends itself to inspecting the entire part: Top, side and bottom as well as metallurgical properties. If you’re looking for unmatched defect detection without complex part to part changeover, HALO is the high-speed inspection system you need.
