Quality Inspection

For our quality inspection stations we design the software separately for each customer: the program, operator interface and system software are shaped by that line's product, defect types and way of working. PIROBOTIK Quality Check, PIROBOTIK Measure, OcrVision and Pi-Vision are separate programs we have developed with this approach.

On surfaces such as textile, glass and metal, defects are hard to define with rules, and different colors, patterns and surfaces require many of them. PIROBOTIK Quality Check therefore combines classical methods such as advanced filtering, segmentation and measurement with deep learning in the same application, and users can introduce a new defect type with a few examples.

The vision decision is passed to the PLC instantly; a faulty product is pushed off the line by a pneumatic pusher (piston) triggered by the NOK decision and drops into the reject bin. The image and result of every product are saved, and production, OK and NOK counters, reports and charts are shown on the operator screen.

Some of our quality inspection stations running on the shop floor: deep-learning inspection of automotive headrests, shape, notch and grille checks on plastic parts, hole position measurement on car doors and inspection of blood group gel cards.
