ABSTRACT:
A confocal spacer switch for a fast, non-contacting determination of the spacing includes a point-shaped element that simultaneously transmits and receives light, imaging optics that form an image of the light-emitting element on a switching range and a light detection device that is coupled to the light-receiving element and emits a signal if an at least partially reflecting object enters the switching range and reflected light falls onto on the light-receiving element. The light-emitting and the light-receiving element preferably is realized with an optical waveguide end. As a result, the optical spacer switch can be divided into two modules that are connected via the optical waveguide, wherein a purely optical module can be realized in a compact and lightweight manner. A method for inserting components on substrates, uses the spacer switch, for which the insertion speed of the components is reduced immediately prior to inserting them. Thus, the impact of the component with the substrate is reduced, for an on the whole fast insertion operation.
