ABSTRACT:
A device for fitting printed circuit boards (5) with contact pins (7), comprising at least one insertion device (1) for inserting at least one contact pin (7) into a printed circuit board (5), at least one measuring device (3) for measuring the angle of insertion (θ) between the at least one inserted contact pin (7) and the printed circuit board (5), wherein the measuring device (3) comprises a sensor assembly (9) having at least two sensors (11) arranged at different heights above the printed circuit board (5) in such a way that the contact pins (7) can be detected by the sensors (11). At least one of the sensor assemblies (9) and the printed circuit board (5) are capable of being displaced in a plane parallel to the printed circuit board (5). The angle of insertion (θ), between the contact pin (7) and the printed circuit board (5), is determined using the relative speed between the printed circuit board (5) and the sensor assembly (9) and from the time difference for the sensors (11) to detect the contact pins (7). The measuring device (3) may connect to the insertion device (1) in such a way that a resulting measurement, taken by the measuring device (3), may be transmitted to the insertion device (1), which is capable of readjustment in response to the transmitted resulting measurement.
