Lion Systems, your partner in research, development, process optimization and quality control.

A smart combination of different highly specialized optical sensors and software solutions enables Lion Systems to help you during the development and during your process optimization by increasing the production volumes by means of optical analysis. This allows you a fast and simple defect analysis in manufacturing, development and quality control.

Using long wave infrared cameras enables Lion Systems to perform thermal analysis on your manufacturing tools, machines and products.
By combining above cameras to MSC and PROTrack software creates optical systems for synchronous measurement and analysis of complex development, manufacturing and quality control processes.

In industrial applications infrared cameras are used in the fields of:

• Building thermographs for identifying insulation problems, water damage and localization of hidden pipes and cables.
• R&D for thermal optimization, spectral thermographs and material testing.
• Process optimization, quality control and lifetime analysis in the stamping, molding and injection molding tools, in electronics.
• Predictive maintenance in mechanical and electrical assembly.

Quality assurance in photovoltaic manufacturing

The photovoltaic industry experienced huge growth during the last several years. As renewable energy plays an increasing role in our daily lives, photovoltaic energy has become an important part in renewable energy.

Warranties from supplier on photovoltaic modules are significant and are expected to last 20 years or longer. Right now no test equipment was available to verify the cell and module quality online in the manufacturing process. 

Lion System has developed a new quality assurance test tool based on the electroluminescence imaging technology. The electroluminescence imaging is possible when applying some electrical current on the photovoltaic cells or modules. The PV modules immediately start shining in the near infrared light range, not visible for the human eye. By means of new high resolution near infrared InGaAs cameras cell damages or manufacturing defects are becoming visible due to variations in the homogeneity of the cell brightness. Defect cells in a module are shining different and visualize silicon defects, diffusion faults, micro cracks or defect conductive paths.

In PV module manufacturing electroluminescence imaging is now available as a non destructive optical quality assurance test in cell sorting directly at the beginning of the assembly line. It helps sorting the incoming PV cells according to homogeneity and defects to build up modules with defined cell performance.

A second electroluminescent test station is useful after the stringer, where the manufacturing process applies some mechanical stress on the cells. It is the last place where reparation of defect cells is still  possible before being assembled into a module.

A third electroluminescent test is of interest in the flasher module. Measuring the module quality directly with the flasher results gives you a unique end of line quality document in combination with the flasher result for the customers. The document certificates that the module is mechanical fine. The document is of help to encounter warranty claims from customers having problems with the module performance.

Plastic sorting 

Our daily consumption and industrial production is constantly increasing the amount of waist. In order to minimize the influence on the environment intelligent recycling practices are needed. Integrating a NIR camera with a spectrograph lens into a waste sorting machine allows a fast wavelength analysis from the different plastic materials passing on the belt. The spectral resolution of the plastic materials enables the machine to easily sort the different PP, HDPE, PE, PVC, PET, PS materials in the plastic recycling process. The sorted materials will then easily be integrated into the recycled material flow.

Quality surveillance in the steel industry

Lion Systems is working for the steel industry on a monitoring system in quality surveillance of some processes in the steel mill.  The system is designed to automatically detect defects on steel beams. The defect observation system is working with a high dynamic range camera positioned on top of the beam guidance combined to an industrial LED lighting.
