Procedure and system for inspecting a component (1) with leads to determine its fitness for assembly before the component is placed on a circuit board. A narrow illuminating beam (10) is directed from a light source (9) at a light-sensitive detector (11). The component (1) is moved in relation to the illuminating beam so that at least one of the leads (4) of the component passes through the illuminating beam and so that the position of the gripper (7) holding the component as a function of time is known. The position data of the gripper is registered. The signal produced by the light-sensitive detector as a result of the illuminating beam being intercepted and shadowed by the lead is registered. Based on the position data of the gripper and the signal produced by the light-sensitive detector position coordinates of a specified lead in relation to the gripper are determined in order to determine the position error, and, if a position error occurs, the position coordinates of said lead of the component are corrected to eliminate said error for making the insertion of the component possible. |
