This paper describes a new application for servopneumatic drives. In a battery module for automotive applications the pouch cells are clamped between frames. During the assembly the frames needs to be clamped permanently. So a clamping system comprising two drives was developed, which moves four clamp fingers each alternating. In the first chapter the application is described in detail. The second chapter includes a comparison of servoelectric and servopneumatic drives for this application with respect to energy consumption, installation space and purchase cost. The developed clamping unit is described in chapter three as well as a verification of the influence of the preload force on the straightness of the stack. At the end of this paper the conclusions are summed up.

This thesis investigates the opportunities and challenges in battery assembly technology for tool manufacturers in the sectors of e-mobility and energy storage systems in the Nordics. The research aims to understand how equipment manufacturers can contribute to the advancements of batteries and their assembly, ultimately fostering innovation and sustainability in these industries. The background and context of the study highlight the rising importance of battery technology in the Nordics, driven by the growing demand for e-mobility and energy storage solutions. The objectives of the thesis focus on identifying the current battery assembly methods, factors driving the choice of assembly methods, and the challenges and opportunities for innovation in assembly technology. A mixed-methods approach was employed, combining a literature review, surveys, and interviews with key industry players and experts. The collected data were analysed to identify patterns, trends, and relationships related to the research questions utilizing Thematic analysis on interview results and data visualization on survey results. The findings reveal that tightening, adhesives, and laser welding are the most common battery assembly methods in the Nordics, with automation being favoured for high-volume production. Factors such as production volume, product complexity, cost considerations, quality requirements, and available expertise drive the choice of assembly methods. The study also highlights challenges related to adaptability to new tech, cost and flexibility, safety, and environmental sustainability in terms of serviceability, recyclability, and reusability, while opportunities lie in advanced automation, modular assembly approaches, and improved recyclability. The conclusion emphasizes the role of equipment manufacturers in contributing to battery advancements through compliance with regulations, collaboration with industry stakeholders, and leveraging competition for innovation and quality improvement. The study's significance lies in providing valuable insights and guidance for battery assembly equipment manufacturers, promoting market growth, and facilitating sustainable development in the e-mobility and energy storage sectors. / Denna avhandling undersöker möjligheterna och utmaningarna inom batterimonteringsteknik för verktygstillverkare inom områdena e-mobilitet och energilagringssystem i Norden. Forskningen syftar till att förstå hur utrustningstillverkare kan bidra till framstegen inom batterier och deras montering, vilket i slutändan främjar innovation och hållbarhet inom dessa branscher. Bakgrunden och sammanhanget i studien belyser den stigande betydelsen av batteriteknik i Norden, driven av den ökande efterfrågan på e-mobilitet och energilagringssystem. Avhandlingens mål fokuserar på att identifiera nuvarande batterimonteringsmetoder, faktorer som driver valet av monteringsmetoder samt utmaningar och möjligheter för innovation inom monteringsteknik. En blandad metod användes, vilket kombinerade litteraturgenomgång, enkäter och intervjuer med ledande branschaktörer och experter. De insamlade data analyserades för att identifiera mönster, trender och relationer relaterade till forskningsfrågorna, genom tematisk analys av intervjuresultat och datavisualisering av enkätresultat. Resultaten visar att åtdragning, limning och laserplåtsvetsning är de vanligaste batterimonteringsmetoderna i Norden, där automatisering föredras för produktion i stora volymer. Faktorer som produktionsvolym, produktkomplexitet, kostnadshänsyn, kvalitetskrav och tillgänglig expertis påverkar valet av monteringsmetoder. Studien belyser också utmaningar relaterade till anpassningsförmåga till ny teknik, kostnad och flexibilitet, säkerhet samt miljömässig hållbarhet avseende serviceförmåga, återvinningsbarhet och återanvändbarhet. Samtidigt finns det möjligheter inom avancerad automation, modulära monteringsmetoder och förbättrad återvinningsbarhet. Slutsatsen betonar verktygstillverkarnas roll i att bidra till batteriframsteg genom att följa föreskrifter, samarbeta med intressenter inom branschen samt utnyttja konkurrensen för innovation och förbättring av kvalitet. Studiens betydelse ligger i att ge värdefulla insikter och vägledning för tillverkare av batterimonteringsutrustning, främja marknadstillväxt och underlätta hållbar utveckling inom e-mobilitets- och energilagringssektorerna.
