Automatic Optical Inspection / [aoi]

Automatic Optical Inspection


Quality control by means of image processing

Automatic optical inspection [aoi] is one of the most effective and important factors in ensuring quality in the manufacturing industry.

With manual assembly, there is a possibility that components are missing, twisted or mounted offset. It is therefore important to identify and correct these errors before the next step in the process.

In the [aoi] module, each work step is compared to a reference image using image processing. If an assembled component is incorrectly installed, this is detected by the system and the assembly force is notified of the error. If a component is correctly installed, the system switches to the next work step autosynchronously. And that in a fraction of a second.

Test variants available include edge comparison, NCC, color comparison or barcode recognition.

The automatic optical inspection in use

Depending on the size of the component or the size of the objects to be detected, a wide portfolio of cameras and lenses can be selected. The perfect constellation of these components is calculated using a formula and tested with your component under test. This ensures that the right hardware is used for each application.

The lighting of the workplace plays a decisive role for process-safe [aoi]. External influences, such as changing solar radiation, must be excluded as far as possible. We accomplish this with a dimmable lighting unit developed in-house. Here we have various standard sizes on offer and can construct the exact size to suit your workplace if required. Of course, these are power-saving LED lights.
