Vision solutions for EV battery production
Intelligent vision systems provide the key to higher productivity, greater efficiency and total quality assurance and help manufacturers achieve highest product quality, consistency in the production and minimizing waste.
Machine vision solutions can be used in several steps of the lithium battery production such as battery module assembly, Cell stack assembly; gap filler applications, tightening of modules, cover sealing and cover to tray assembly.
Pick & Place
The final step of battery assembly is the mounting of the cover onto the battery tray. When joining a battery cover to its tray, more than 100 fasteners can be needed. This requires a fast application to achieve a short cycle time.
Precise positioning of the joining tool is crucial for the assembly process step to deliver the highest quality standards. MONO 3D performs pick-and-place of battery covers precisely and enables fast and reliable robot guidance which is the key driver for high-volume production. Fast image processing algorithms during computing increase the speed and accuracy of the tightening process. The MONOxD Software calculates the 3D coordinate transformation and sends the offset to the robot controller to optimize the tool path.
