A method for the exact three-dimensional micropositioning of bodies of different geometry and / or dimensions in the space

摘要

The invention relates to a method for the exact three-dimensional micropositioning of bodies of different geometry and / or dimensions in the cream and includes a device for the controlled motor moving the body in the x -, y - and z - the axial direction, wherein this device at the same time a highly accurate position determination in the aforementioned axes allows. With the aid of the device may be any desired target points of a predeterminable starting point can be controlled or. The body is to be positioned according to the invention in the beam - or scanning region is in the x - and y - the axial direction of the preliminary point sensors with a known predetermined distance in the given coordinate system at the respective target point axes selectively moved as far as - or. By recourse to the means for moving and for determining the position, the coordinates of the inlet and the exit of the body to be positioned, based on the beam - or scanning region, determined. The process is repeated for the further axes, so that as a result, the actual geometry and the dimensions of the body as well as tolerances of the device be taken into account correction - data set can be made available, in order to the theoretical distance value between the moving body and the starting point of the real distance value for the purpose of the highly accurate positioning of the body, in relation to the destination to be adapted to.
