Method and apparatus for active wedge error compensation between the two objects which can be positioned substantially parallel to each other

摘要

This invention regards the method and the device in order to expand the migration length namely control displacement of the available linear actuator in stroke of imprint or embossing finish. The wedge error compensating head (2) has, the moving element (4) and the stationary section (3) and, three linear actuators (8) with at least. Each linear actuator (8), the stationary section (3) or the moving element (4) it is connected on the one hand in one end, the moving element (4) or the stationary section (3) it is connected on the other hand the wedge (9) by in the other edge. The wedge (9) with, it is possible to compensate with wedge error and each sub component of the system roughly. The linear actuator (8), it is used for the precise compensation of wedge error only is. This way, because in the imprint stroke which uses the linear actuator, it is possible to utilize sufficient control displacement.
