01 · Missing component

A missing part that made it past manual inspection.

Checking assembly completeness and the presence of required components — one of the most common enquiries, because a missing component is easy to miss at line speed and easy to show unambiguously in an image.

A missing component — a screw, a gasket, a clip, an electronic sub-assembly — is a defect that's easy to miss visually at high line speed, even though it is obvious in a calm, still image. That gap between operator pace and inspection pace is exactly why assembly completeness is usually one of the first candidates for automation.

In AIVQC Trainer, the model learns to recognise a complete, correct assembly from representative OK images, then detects the deviation from that pattern — a missing element at a specific point in the assembly. Controlled product positioning matters most here: the more repeatable the position in frame, the more reliable the detection.

The OK/NOK decision is made locally at the AIVQC Production station, in step with the line, and passed on to the process over Modbus TCP — with no image sent externally.

When this scenario usually works well

01 The product reaches the camera in a repeatable, controlled position
02 The missing element is visible in the image — not hidden under another part
03 OK and NOK examples exist from real production, not only from a lab setup
04 The number of assembly variants is limited, or can be split into separate recipes

What the pilot report shows

Validation measures not only whether the model detects a missing component, but also how often it wrongly rejects a complete product (false accepts and false rejects) — both values go into the qualification report alongside decision time on the target hardware.

How this works in practice

AIVQC Trainer → AIVQC Server → AIVQC Production

FAQ

Missing component

What if the missing element is sometimes partly obscured?+

That is exactly what the pilot assesses — qualification includes checking whether the camera angle and position show the assembly point clearly enough. If not, the report states that as a limitation.

Will one model handle several product variants?+

It depends on how similar the variants are. AIVQC Production uses recipes, so different variants can have a separately configured inspection on the same station.

Other applications

Incorrect assembly

Detecting reversed, displaced or incorrectly seated parts — a defect that differs from a missing component in that the part is present, just in the wrong orientation or position.

↗03

Flash and deformation

Identifying moulding, geometry and product-edge defects — a classic example of an irregular defect, where classic geometric rules quickly stop being enough.

↗04

Cracks and damage

Visually detecting scratches, cracks and surface damage — a defect where the stakes can be high, since damage may affect both function and visual appearance.

↗05

Labels and print

Verifying the presence, orientation and legibility of markings — a scenario that combines a completeness check (is the label there at all) with a print-quality check (is it legible and correctly placed).

↗06

Contamination

Detecting foreign objects, dirt and surface deviations — inherently the most unpredictable scenario, since contamination can take almost any shape.
