Quality control

Machine vision inspection systems

Turn defined quality criteria into repeatable fixed-camera, in-line automated optical inspection (AOI) and automated quality control checks. We integrate cameras, lenses, lighting, inspection software, production controls and reject handling around the defect, line speed and evidence your process requires.

Direct answer

What is an automated optical inspection system?

A fixed in-line automated optical inspection system uses controlled cameras, lighting and decision software to check visible product features at production speed. It can measure, verify presence or assembly, detect surface or packaging defects and trigger a confirmed pass, reject, alarm or review response.

01 / Engineering focus

Inspection starts with an objective rule

The best systems begin with an observable, measurable difference between an acceptable product and a reject. We define the inspection window, tolerances and decision logic before selecting resolution or software tools.

Component presence and correct assembly
Position, alignment and orientation checks
Dimensional and geometric measurement
Surface defect, print, label and packaging inspection
Colour, fill level and closure verification

02 / Engineering focus

A reject path that protects the process

Detection only creates value when the affected item is reliably contained and defect escape risk is addressed by the line response. Reject timing, part tracking, full-bin detection, confirmation sensors and fault response are included in the system design.

Positive reject confirmation
Locked or controlled reject collection where required
Fail-safe response to missing confirmation
Production totals and reject reason reporting

System sequence

Engineer the complete decision loop.

Every stage is tested against the product, timing, interfaces and agreed response.

Define

Agree the defect catalogue, tolerance and decision boundary.

Image

Select optics and lighting that reveal the required feature.

Prove

Challenge the inspection with representative variation and rejects.

Contain

Remove or stop affected product and confirm the response.

Typical applications

Application questions

What manufacturers ask.

These answers provide a starting point. Product trials and line data determine the project specification.

Can a camera inspect every product at production speed?

Potentially, but exposure time, image transfer, processing time, product spacing and reject response all have to fit within the available cycle. We calculate the complete timing budget rather than considering the camera alone.

Can inspection results be recorded?

Yes. The required result records, counters, timestamps and image-retention policy can be defined around your quality and traceability needs, subject to agreed storage and system interfaces.

Do you need samples of real defects?

Yes wherever possible. Representative acceptable parts, known rejects and natural process variation give a much stronger basis for trials and acceptance than ideal samples alone.
