Battery production

The production of lithium-ion batteries requires maximum precision. In this ultra-modern manufacturing process, carrier films are combined with an anode and a cathode to form an energy cell. The anode consists of a copper film coated with a…

During the production of battery cells, electrode and separator films must be guided reliably. Optical optoCONTROL micrometers detect the required edge position for web edge control. Operating several micrometers enables the concurrent detection…

Laser sensors from Micro-Epsilon are used to measure the thickness of electrode materials. They are attached opposite the strip material. Based on synchronization combined with the precise sensor alignment, high measurement accuracy and measuring…

Electrodes must be coated with extreme precision in order to maintain tight manufacturing tolerances. This is why laser scanners from Micro-Epsilon inspect the coating profile on the strip edge which enables the detection of anomalies and…

Films may have curvatures and deformations after longitudinal cutting. In order to detect these deviations reliably, laser profile sensors from Micro-Epsilon are used. Laser scanners measure the profile of the film on the edge in order to…

Confocal chromatic sensors from Micro-Epsilon monitor the coating thickness of wet materials. Installing several sensors next to each other enables concurrent determination of the homogeneity of the coating over the complete strip width. Their…

After the battery cells have been assembled, laser scanners from Micro-Epsilon inspect their completeness and position. Therefore, a 3D image is generated which is then compared with the CAD data. As well as profile information in high…

scanCONTROL laser scanners inspect the presence and dimension of adhesive beading. They are mounted on the dispenser in order to control the quantity applied and the distance from the dispenser. Their high resolution enables them to reliably…

Thermal imaging cameras monitor the first charging process of batteries. These provide an insight into the temperature distribution and possible short circuits. The hot-spot detection feature automatically recognizes and outputs deviations from…
