Abstract
A component placement device is provided. The component placement device includes a machine frame, a subframe supported by the machine frame, and a component pickup unit. The component pickup unit is movable relative to the subframe. The component pickup unit is movable by a first drive at least in a direction of movement. The component placement device includes a movable counter-mass being movable relative to the subframe by a second drive in a direction opposite to the direction of movement of the component pickup unit to at least partially counteract a reactive force exerted on the subframe by the component pickup unit during movement of the component pickup unit in the direction of movement relative to the subframe.
Claims13
A component placement device comprising:
- a machine frame;
- a subframe supported by the machine frame;
- a component pickup unit that is movable relative to the subframe, the component pickup unit being movable by a first drive at least in a direction of movement;
- and
- a movable counter-mass being movable relative to the subframe by a second drive in a direction opposite to the direction of movement of the component pickup unit to at least partially counteract a reactive force exerted on the subframe by the component pickup unit during movement of the component pickup unit in the direction of movement relative to the subframe, wherein a mass of the moveable counter-mass is different from a mass of the component pickup unit, wherein the component placement device includes a control unit for delivering a control signal for controlling the movement of the component pickup unit in the direction of movement, wherein the control unit is provided with an actual position of the component pickup unit as a setpoint for calculating a desired position of the counter-mass.
A method for driving a component placement device comprising at least a machine frame and a component pickup unit which is movable relative to a subframe supported by the machine frame, the component pickup unit being movable at least in a direction of movement by a first drive, wherein the component placement device includes a movable counter-mass being movable relative to the subframe by a second drive in a direction opposite to the direction of movement of the component pickup unit to at least partially counteract a reactive force exerted on the subframe by the component pickup unit whilst moving the component pickup unit in the direction of movement relative to the subframe, wherein a mass of the movable counter-mass is different from a mass of the component pickup unit, wherein the component placement device includes a control unit for delivering a control signal for controlling the movement of the component pickup unit in the direction of movement, wherein the control unit is provided with an actual position of the component pickup unit as a setpoint for calculating a desired position of the counter-mass.
