The concept of traceability in manual assembly is pretty straightforward: When a customer calls about a product, whether it’s because of a perceived defect or a question about a part, you can find that exact unit and follow it all the way through the assembly cycle.
On most factory floors, traceability is much less straightforward. An MES shows you what the details about the line on which a product was assembled. And if you check past schedules, you can figure out who worked on that line when the unit was built — even who worked each station.
So you’re starting to cobble together traceability from the factory, but you’re still lacking a great deal of information about that unit’s progression down the line and what might have occurred during the assembly process to compromise its integrity.
In most cases, the best you can do now is ask the line associates who worked that shift what they remember. And if the unit wasn’t assembled yesterday (or even better, a few minutes ago), memory distortion is likely to impact the accuracy of recall.
Traceability: Video doesn’t forget over time
Traceability doesn’t have to rely on imperfect human memories to be accurate. And video cameras in a factory aren’t new. But here are three ways Drishti makes traceability better than anything else in the market today:
- Our video cameras see the entire line AND every station: We hang a camera on every station so each process being performed is captured on camera. But we also give users an easy way to watch multiple videos at once — even an entire line — to watch an item travel down the assembly line in real time or in the past.
- We make our videos searchable in less than a second: You’re used to using YouTube at home. That same functionality powers Drishti. Type in a serial number and boom, every video with that unit appears. Or you can filter by date, time, shift, line and station.
- We back those videos with data, powered by AI: Video produced by a Drishti camera is annotated, either by you, or with our neural networks. So instead of just watching live or past video, you can see critical information at the same time. How long did the unit stay in station? Was every critical step performed?
Essentially, we’ve taken the guesswork out of traceability. You no longer have to build a case from disparate sources, some more reliable than others. You can literally release your brain from having to hold onto past assembly memories and free that space for more critical work, confident that if a customer calls, you can have an answer in short order.
