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…

Optical optoCONTROL micrometers detect the required edge position of electrode and separator films. Due to their high measuring rate, optoCONTROL micrometers are also suitable for monitoring dynamic production processes.

In order to measure the thickness of electrode coatings, optoNCDT laser sensors are attached opposite the strip material. Based on synchronization combined with the precise sensor alignment, high measurement accuracy and measuring rates are achieved.

In order to maintain tight manufacturing tolerances, laser scanners from Micro-Epsilon inspect the coating profile on the strip edge. This is how anomalies and undulations are detected. Modern interfaces allow for the scanCONTROL SMART sensors to be directly integrated into the control system.

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

Confocal chromatic sensors from Micro-Epsilon monitor the coating thickness of wet materials. Their high resolution enables them to reliably detect any minor deviations.

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 while regulating the distance control of the dispenser. Their high resolution also enables to reliably detect even the finest of beads.

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…

A high-resolution thermal imaging camera, thermoIMAGER TIM QVGA from Micro-Epsilon, monitors the thermal properties of the drive batteries either during unstacking or on a conveyor belt. For this measurement task, the camera is mounted stationary…
