exact placement angle

 Pickup/placement station: Place component 6

 Component sensor: during the next star step,

the component presence/component height is

checked at segment 8.

Star position 180°

 Vision system: Optically centers a component

for another gantry (optical recognition of

individual gantries is no longer synchronized

against one another).

 DP station: Rotates component 11 into its

exact placement angle.

 Pickup/placement station: Places component

 Component sensor option: During the next

star cycle, the component presence/

component height check is performed for

segment 9.

6.2.16 Placing Component 12

6.2.17 Pickup and Placement Cycle For the Next Components

 After all the components of the first head cycle have been placed on the board, the gantry axes move

the placement head to the pickup position of the next pickup cycle.

 The next pickup cycle is performed for components 13 - 24 (7 - 12 for C&P6).

 The subsequent pickup cycles follow the same procedure. If necessary the machine performs repair

cycles.

6.2.18 Segment with a "Defect Component"

If the optical centering of a component (ident. error) or the pre-placement vacuum check (alternatively,

component recognition before placement) fails, the component will not be placed and will remain on the

nozzle.

 The turning station still rotates this nozzle into the pickup angle for the new component, if this

segment is in the rotary position.

If this segment is in the pickup position:

 The reject procedure is activated and

 The X/Y gantry axes move to the reject position for that gantry,

 The star rotates the segment into the reject position,

 The component is rejected with an air blast,

 The new component is taken up.

The rejected component is then placed during a repair cycle, performed after all the set placement cycles

for this placement head have been completed.

6-26: Placing component 12

Star position 330°

 Vision system: optical centering of component

6 on other gantry

 DP station rotation of nozzle 4 into the pickup

angle for the next placement cycle.

 Pickup/placement station: Place component

 Component sensor option: during the next star

step, the nozzle length is measured at

segment 2.

6.2.19 Completing Board Placement

 The SIPLACE placement station activates the conveyor system and moves the board into the output

conveyor.

 Finally, the SIPLACE placement station reports the number of components consumed (placed and

rejected) to the line control computer (LC) SIPLACE Pro.

 The OIS (Operator Information System) compiles the placement statistics which relate to the data

set at the station, the programed panels or the last reset time. This data is used for optimizing the

process.

 The machine is now ready for the next board.

6.2.20 Detailed Rotation of DP Station 1. Swivel In

6.2.21 Positioning into Pickup Angle

6-27: Detailed rotation of DP station, 1. Swivel in

 Diagram 1 shows the initial position (state after

reference run).

 From the initial position, the stepping motor

rotates by 90° for swivel-in.

 The DP station swivels in and contacts the

sleeve (incremental disk).

 The stepping motor is monitored by the light

barrier on the cam disk.

 Diagram 2 shows the status after swiveling in.

 This is the start command for the DP axis

drive.

6-28: Detailed rotation of DP station, positioning into pickup angle

 The DP axis positions the segment to the

relevant zero pulse and checks the signal level

at a distance of 3 digits.

 An end position signal is emitted if the actual

position deviation is within the permitted

tolerance.

 There is no difference between the 0° and

180° or 90° and 90° pickup angle.
