Damage that arrives late
A flat blank leaves the laser clean. By the time it has been bent, welded, deburred, and carried to the paint line, it may have picked up a dozen marks. Many are cosmetic, and many are what the customer sees first. A scratch that goes under paint is cheap to fix before coating and costly after.
That is why the check at the end matters. If the last look before paint or shipping is quick and tired, marks get through. A camera station gives that last look a steady light and a steady eye, and passes the odd ones to a person.
What VZSOR checks
VZSOR learns what good parts look like from photos of good parts only. It then flags parts that differ, which can include scratches, dents and nicks on visible faces. A part with a missing feature, such as a hole or a pressed-in nut, may also stand out as different. A heatmap shows where.
It is an operator assist. A person looks at the flagged parts and decides. If the person overrides a FAIL, they write a reason, and the station's verdict is kept next to it. Each part gets a photo, a result, an operator, and a lot or serial number you can export.
Wrong or missing hardware
Because VZSOR compares a part to what a good one looks like, a missing fastener or a clearly different component can be flagged along with surface marks. That is a side effect of how it works, not a promise for every part.
We have not validated this on sheet metal. The one part we have tested is a flat aluminum bracket. Whether it reliably spots a wrong insert or a missing nut on your assemblies is something the pilot would measure. Do not assume it before then.
Size is the main limit
The camera sees an area of about 100 to 120 mm. A bracket, a small enclosure panel or a clip fits. A full cabinet door does not. Large parts would need several views, and VZSOR is not set up today to stitch them together.
Finish matters too. VZSOR has been validated only on mill-finish aluminum, not on brushed stainless, painted, powder-coated or anodized surfaces. If your parts are small to mid-size and plain metal, a pilot is worth a look. If they are large, it is probably not the right tool.
Good fit, poor fit
Good fit
- Small and mid-size bent or stamped parts that fit in one camera view
- Parts where scratches and handling marks cause finish complaints
- A last check before paint, plating or shipping done by eye today
- A single part number that runs often enough to be piloted
Poor fit
- Large panels, doors and enclosures that exceed the field of view
- Painted, powder-coated or anodized surfaces, which are not yet validated
- Judging bend angles or flatness, which are dimensional
- Highly reflective polished surfaces that are hard to light evenly
Limits, stated plainly
- Validated on one part only: a 2 inch by 2 inch mill-finish aluminum L-bracket.
- Large parts may exceed the field of view of about 100 to 120 mm.
- Painted, coated, brushed and anodized finishes are not yet validated.
- Missing or wrong hardware detection is untested on sheet metal.
- It flags suspect parts for a person and does not measure dimensions.
