AOI module for mounting processes and THT assembly

THT assembly and many other mounting processes are still not fully automated due to economical reasons. As a result, such work is usually carried out manually by appropriately qualified employees. Compared to automated processes, however, the risk of faults in manual assembly, such as THT printed circuit boards, is much higher. Monotonous work in particular can easily lead to fatigue and the resulting careless mistakes.

The ideal solution for direct and immediate fault detection in such manual processes would be a high-resolution, automatic optical inspection system directly at the assembly station. At the same time, the system should be completely subordinate to the conditions of the assembly process.

The problems for the realization of such a system are obvious. High resolutions with large image areas are usually achieved by scanning or stop-and-go camera systems.

The open mounting environment results in changing lighting conditions. This poses an extreme challenge to the image processing algorithms, which must provide reliable inspection with reproducible results despite the unfavorable conditions.


MultiEyeS plus

With the MultiEyeS plus, GÖPEL electronic offers a smart automatic optical inspection module for integration into mounting and THT assembly stations. It fully meets the requirements through the consistent use of the latest technologies.

The system concept based on a 47 megapixel image acquisition unit combined with a flexible LED illumination system enables capturing images with outstanding image quality and detail resolution. Real-time monitoring of mounting and placement processes directly at the assembly station is now a reality.

Optionally, by integrating a powerful laser projector, the system offers user-guided assistance during placement by projecting information into the operator's field of view.

A wide range of applications

The MultiEyeS plus assists you with your tasks.

Here is a selection of applications:

  • Assembly of components in casings
  • Assembly of plastic parts
  • Battery cell assembly
  • Manual assembly processes in the automotive sector
  • Incoming and outgoing goods inspection
