Abstract

Laser adjustment allows a new process chain for fast, cost- efficient and highly precise assembly. It can be done without the usually very elaborate exact positioning of the jointing parts since after joining the components are adjusted into the desired position by laser forming. In order to make this new process chain possible an actuator can be joined between the bearer and the relevant functional element. This actuator enable the functional element to be moved into the desired position by conversion of laser energy. After the adjustment it remains in the assembly. For simple adjustment tasks an intuitively controlled design process can lead to solutions to an actuator design. As far as more complex tasks are concerned, like e.g. adjusting the 7 relevant degrees of freedom of all optics in electro- optical transducers, new design principles are necessary. After elucidating the process principle this paper presents the demands imposed on such actuators. Founded on the basic actuators, the integral approach to the actuator design is presented with its complete mathematical description being the basis of the computer-aided procession of all actuator- specific data. Thus it becomes possible to solve the inverse problem of the requirements made on geometry.
