Titel
Self-optimization of robot-based resistance soldering for the assembly of optical elements in solid-state laser systems
Abstract
During the assembly of customized miniaturized solid-state lasers, robot based operations can significantly reduce cycle times and improve performance and quality. Automation of the resistance soldering technique for optical components based on planar technology described in the previous work of Dolkemeyer et. al can be self-optimized to compensate component and process tolerances, cope with different element geometries and therefore reduce planning efforts and facilitate the operator's work.solder pads. Planar adjustment of an optical element and exemplary resistance measurement during soldering process For the automation of the soldering process itself the modification of the system's electrical resistance is measured since this value can be calculated by evaluating the process parameters without supplementary equipment. In addition, it can be used as a documented quality control. The increase of the resistance at the solder's melting point is related to the length of the molten zone and is always continuous even if current and voltage are discontinuous. Presented are the technique for planar adjustment and current results of the automation and self-optimization process.
