Abstract
Abstract An automatic SMD equipping unit utilizes a rotatable and displaceable multiple equipping head (1) with plural suction pipettes (2) and a device carrier (7) that contains processing stations (8). The multiple equipping head (1) executes a collecting event via delivery units (4) whereby it picks up components. The equipping of the printed circuit board (5) from the equipping head occurs in a second procedure, whereby the multiple equipping head (1) need not move back and forth between delivery unit (4) and printed circuit board (5) after every placement of a component (3) onto the printed circuit board (5). The components that were picked up by the suction pipettes (2) are processed by processing stations (8) after the collecting and before the equipping. Here, the components are centered, contacted, measured and tested.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
168 words
A method for equipping printed circuit boards (5) with components (3) using an equipping apparatus having a rotatable equpping head with a plurality of pickup tools, comprising the steps of: collecting components (3) from delivery units (4) by means of said equipping head; subsequently equipping a printed circuit board (5) with these components (3); said delivery units (4) and said printed circuit board (5) being stationary at different locations; moving said equipping head to locations adjacent said delivery units and adjacent said circuit board at the time of collecting or equipping, respectively; providing at least one processing station adjacent said equipping head; rotating said head to provide a clocked passage of said components past said at least one processing station; and processing said components which are collected while they are in position on said multiple equipping head by use of said at least one processing station when said multiple equipping head has been rotated to bring said components into association with said one or more processing stations 8.
Claim 2
Independent Claim
168 words
A method for equipping printed circuit boards (5) with components (3) using an equipping apparatus having a rotatable equpping head with a plurality of pickup tools, comprising the steps of: collecting components (3) from delivery units (4) by means of said equipping head; subsequently equipping a printed circuit board (5) with these components (3); said delivery units (4) and said printed circuit board (5) being stationary at different locations; moving said equipping head to locations adjacent said delivery units and adjacent said circuit board at the time of collecting or equipping, respectively; providing at least one processing station adjacent said equipping head; rotating said head to provide a clocked passage of said components past said at least one processing station; and processing said components which are collected while they are in position on said multiple equipping head by use of said at least one processing station when said multiple equipping head has been rotated to bring said components into association with said one or more processing stations 8.
Claim 3
Dependent Claim
25 words
The method according to claim 1, including the step of simultaneously executing the collecting of components (3) and the equipping of said printed circuit board.
Claim 4
Dependent Claim
27 words
The method accoding to one of the claim 1, including the step of coding the components so that they are identifiable at every location of the apparatus.
Claim 5
Dependent Claim
25 words
