SolarModule EL-quickline 4.0

The Quickline 4.0 is a fast electroluminescence test system for reliable 24/7 use in any PV production line. With the internal transport system and an automatic electrical connection of the PV module it provides images with high pixel resolution for excelent EL image quality. An neural network finds defects automatic, fast and reliable. 

The Quickline supports modules up to 2700 mm in size. To meet the needs of your production line, it is available in 3 different size versions.

Automatic and fast inspection

The SolarModule EL-quickline is a fully automated electroluminescence test system for the PV module production. It is fast, to match todays requirements of high throughput with a cycle time well below 20 seconds.

It is reliable, using high resolution images with 180 µm per pixel and neural networks with deep learning to detect and classify defects. 2 or 4 cooled 12 MPixel CMOS cameras, depending on your cycle time requirements, provide excellent EL image quality.

It is safe, as it uses an integrated transport system with an additional support for thin glass modules and an automatic electrical connection to the module. When needed a centering unit can be added for even better cell positioning over the cameras.

MBJ offers the EL-quickline 4.0 in three different size variants: Standard, WIDE-ECO and MAX.

Automatic image evaluation with deep learning

The system offers fully automatic image evaluation using AI with deep learning approach, visualizing typical production problems like micro cracks, dark areas and stringing issues in high image resolution.

Our neural network-based defect detection is fast, reliable and robust. Each inline system comes with a pre-trained network that already includes microcrack detection.

It can easily be trained with individual defect types matching your production requirements. Defects are shown in the intuitive user interface which, when shown at a repair station, aids a quick repair bevor lamination.

The defect data, including an image of the module, is stored and can be used for your statistic reports when needed.

Cell distance measurement and others functions

We offer addons for even better control of your process, so you can save money and avoid wasting valuable materials.

The cell distance measurement uses an independent illumination / camera setup to accurately measure cell-to-cell and cell-to-glass edges or distances in the inter connection area. It also detects cell edge chips or missing ribbons. The good thing: it has as good as no effect on the cycle time! Ideally used before and after lamination.

The visual inspection can high light lamination issues like bubbles or dirt specs when used in the backend or directly after lamination.

Other options like diode testing or dark current measurement give even more information about your process.

The repair stations visualize errors and error locations directly in front of the workstation where the repair is being carried out.
