Suction frame
The present invention relates to a suction frame for conveying flat workpieces (e.g. circuit boards), a manipulator for equipping the suction frame, and a system for handling flat workpieces, e.g. circuit boards. A method for adjusting a suction frame is also claimed. Overall, the present invention allows suction frames to be equipped in a fully automatic, freely programmable manner for the production of different components within a production line.
1. A system for handling planar workpieces that have dissimilar contours, said system comprising a manipulator, an adapter, a multiplicity of suction units, a transfer station, and a magazine,
wherein the manipulator is connected to the adapter;
wherein the adapter comprises a fluid connector and a line network;
wherein the adapter comprises a multiplicity of coupling receptacles that by way of the line network are connected to the fluid connector;
wherein the coupling receptacles and the coupling heads are mutually adapted in such a manner that each suction unit is in each case coupleable in a latching manner to the adapter, and is decoupleable in an unlatching manner from the adapter; and
wherein at least one suction element of each suction unit in the coupled state is connected through the coupling head to the line network of the adapter.
2. The system as claimed in claim 1 , wherein the transfer station for dispensing one of the suction units to the adapter that is connected to the manipulator provides a suction unit in such a manner that
either the manipulator by way of a linear repositioning movement drives the adapter by way of a free coupling receptacle in the coupling direction toward the coupling head until the latter latches into the free coupling receptacle; or
the transfer station by way of a linear repositioning movement drives the suction unit in the direction of a free coupling receptacle of the adapter that is positioned toward the transfer station in such a manner that the coupling head of said transfer station latches into the coupling receptacle.
3. The system as claimed in claim 1 , wherein the transfer station for removing one of the suction units from the adapter that is connected to the manipulator stands by in such a manner that the manipulator and the transfer station by at least one of a movement of the manipulator and a movement of the transfer station for removing a suction unit that is held in the adapter are mutually positioned in such a manner that an activation means of the transfer station unlocks a latching mechanism of the suction unit, and the coupling head of the suction unit and the coupling receptacle of the adapter are subsequently separated from one another by a relative movement between the transfer station and the adapter.
