Counting and sorting parts by hand is slow, costly and inconsistent — and it depends entirely on people staying alert. Over a shift, fatigue, lapses in concentration and simple human error are unavoidable, and every miscount or missed defect has a cost. 3HLE removes that variable: our Retina A.I. vision counts and sorts your parts automatically — the same way, every time.
Our aim is to give you the best of both worlds: the accuracy, speed and tirelessness of a machine — while keeping the flexibility and judgement of a skilled human. The machine takes the repetitive, error-prone work; your people stay free for what only people do well.
Built for the parts that defeat other systems
These are tiny gear wheels on a vibratory feeder — small, reflective and scattered across a scene that shades from bright to dark, with a loose pile in the corner. It is exactly the high-variation, low-contrast situation where ordinary vision gives up. Retina A.I. vision finds and counts every one.
Every part, every time — without the human factor
A camera never gets tired, distracted or bored. Retina A.I. vision checks every part at full line speed, with the same accuracy on the first part of the day and the last. No fatigue, no end-of-shift mistakes, no lost concentration — just a reliable count and a consistent sort, around the clock.
Reflective parts, any orientation
Shiny metal parts in random orientations stop many systems cold. 3HLE handles them exactly as they arrive — no special fixturing, no careful presentation, no operator arranging parts on a tray.
Parts that touch and overlap
Parts rarely arrive neatly spaced. Retina A.I. vision counts them even when they touch, overlap or pile against each other — straight from the bin or tray, with no manual separating.
Intricate parts like coil springs
Coil springs, with their repeating helical shape, are another classic headache for ordinary vision. Retina A.I. vision counts each one individually, even where they cross or touch end to end.
Beyond counting: sorting and handling
The same Retina A.I. vision does more than count. It can sort parts — good versus defective, or by type, size or model — and guide a robot to pick, place and palletise them. You automate the whole step, not just the tally: counting, quality sorting and handling in one reliable system.
What it means for your line
- Consistent quality — every part checked the same way, every shift.
- Fewer errors and less scrap — no miscounts or missed defects from human fatigue.
- Higher throughput — counting and sorting at line speed, around the clock.
- Free up your skilled people — move them off repetitive counting onto higher-value work.
- Full traceability — every count and decision is recorded.
