Abstract: A system for mounting electronic components on a substrate includes component holders each configured to hold an electronic components to be mounted on the substrate. A revolving device is configured to revolve the component holders along a pre-determined path so that each one of the component holders is moveable into a component receiving location for receiving a respective electronic component and/or a component mounting location for mounting the respective electronic component on the substrate. An actuator is configured to actuate a respective component holder in the component receiving location and/or the component mounting location. A safety device is configured to determine whether the respective component holder to be actuated by the actuator is properly placed in an operative position on the revolving device. The safety device is arranged separately from the actuator and is spaced apart from the actuator along the pre-determined path.

Abstract: The present invention relates to a control method in the feeding of plate shaped workpieces to a work station, comprising feeding of the workpiece (8) to a control station (1) at which control station (1) it is controlled that the desired number of workpieces (8) are fed to the work station (7), whereby weighing is performed at said control station (1) by at least one electronic weighing unit (3) that transmits signals to a control unit (6) arranged to signal for the feeding of the workpiece (8) to the work station (7) when the transmitted weight signal lies within a predetermined set point range, wherein said weighing unit (3) is kept fixed on top of a fixing structure (4) and in that control takes place directly at the control station (1) before initiating moving of the workpiece (8) to the work station (7), in order to give reliable moving of a single workpiece (8) at the time in the work station (7).
