BST CELLInspection precisely measures all the quality-related geometry of a cell during the notching process, directly after lamination or before stacking. Precise, high-resolution matrix camera technologies are used in all applications. In addition, different lighting concepts are used for different applications, allowing all 4 layers of a mono-cell to be measured directly after lamination, for example. The image processing system is easy to connect to any other BST web guiding system. The closed loop used here adds value to the production process previously mentioned. The intuitive, web-based user interface also provides a live image of the cell currently being measured, and its open interfaces make it easy for any machine manufacturer to integrate into existing systems.
