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.
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.
