Verify Every Primer Band, from the First Stroke to the Urethane Bead
Add a real-time inspection layer to every windshield with Roboflow Vision AI for windshield primer inspection. Built for glazing lines and glass plants where the primer band is what lets the urethane hold the glass in place, and a skip, a thin spot, or a drip on the vision area is hard to see once the next step begins.
Coverage on every glass:
- Confirm primer is present and continuous around the full perimeter of every windshield, backlite, and fixed side glass, with a model trained on your own glass and primer.
- Measure primer width and its offset from the glass edge, and flag any section outside your spec.
- Detect skips, gaps, thin spots, and streaks where the applicator lifted or ran dry.
Low contrast and changing light:
- Find black primer on black ceramic frit, where the contrast is low, by training on images from your own line and lighting.
- Keep results steady across glossy glass, reflections, and shifts in ambient light, and add images of new conditions to the dataset as they appear.
- Detect overspray, drips, and primer on the vision area of the glass, where it will show after the glass is installed.
Before the bead and after:
- Pass or fail each glass before the urethane bead is applied, so a reject never reaches the body.
- Check the urethane bead itself with adhesive and glue bead inspection on the same station.
- Save an image and result per glass, tied to the part or VIN, alongside glass defect detection for the glass itself.
Bring intelligence to every primer band today. Stop a missed stroke from becoming a weak bond, a water leak, or a warranty claim.
Frequently asked questions
What is windshield primer inspection with Vision AI?
Windshield primer inspection with Vision AI uses cameras over the glazing cell or primer station with a trained computer vision model to check that primer covers the full bonding area of each glass, measure its width and position, and flag skips, thin spots, and overspray before the urethane bead is applied. It works with adhesive and glue bead inspection and glass defect detection.
Why does primer coverage matter?
Glass primer promotes adhesion of the urethane that bonds the windshield to the body and helps protect it from UV, working together with the ceramic frit band. A gap or thin spot in the primer is hidden under the trim once the glass is installed, so the time to catch it is before the bead goes on.
Does windshield primer inspection support FMVSS 212 and IATF 16949?
Windshield primer inspection supports the bond quality behind FMVSS 212 (the US standard for windshield retention in crashes) and the error-proofing and traceability expectations of IATF 16949 (the automotive quality management system standard), with an image and result for every primed glass.
Roboflow serves as the inspection engine, and your quality and manufacturing engineering teams own the primer spec, acceptance criteria, and validation.
Can it integrate with our glazing cell, PLC, and MES?
Yes. Roboflow writes pass/fail and primer measurements to a PLC tag over OPC UA, Modbus TCP, or MQTT, so the glazing cell can hold or reject a glass before the urethane bead, and sends results and images over REST or to a database for MES and SCADA platforms such as Ignition.
