4.1 Placement of Snap-In Components (from R16-2)

64 Bedienungsanleitung OSC Package User Guide OSC-Paket 05/2019

After the first board has been completely produced, it will be transferred to the output section or the

configured inspection station and marked for manual inspection. The operator has to inspect every

snap-in placement position and confirm whether the placement is correct or not. If correct, the cor-

responding Z-axis position will be stored as reference position and used as placement position for

all subsequent boards. If not correct, the measured height will be ignored and the operator must

confirm it again for the next board. The snap-in check is active now. If the Z-axis position deviates

more than the snap-in threshold value from the reference position in a subsequent placement, an

error is reported.

The height reference values are not uploaded to SIPLACE Pro. Up to R18-2, the height reference

values have to be taught again when the job is changed at the placement machine or the machine

is shut down. As of R19-1 they are stored locally on the machine and do not need to be taught

again.

NOTICE

Using SIPLACE Smart Pin Support

For reliable snap-in detection it is recommended to set support pins close to the snap-in

placement positions. Detailed information on Smart Pin Support can be found in the

SIPLACE Smart Pin Support Operation and Configuration User Manual, item no.

[00197001-xx].

4.1.1 Procedure

The following overview lists the single work steps that have to be performed in the specified order

to place snap-in components.

4.1.2 Application Example

Step 1: SIPLACE Pro

► In the Station Editor under Placement Station,

enable the OSC Package option under Installed

options.

Step 2: SIPLACE Pro

► In the Component Shape Editor, select the Snap

In feature as placement process for the compo-

nent shape.

Step 3 and Step 4: SIPLACE Pro

► In the Handling tab, enable the Snap In Z-

threshold option in the Placement group for the

component shape.

► Define a Z-threshold value in mm.

The threshold value must be > 0.

Default value: 0.500 mm

The first board has to be inspected and confirmed as described in Step 5 and Step 6 below. After

this, the machine uses the Z-threshold value to determine whether the snap-in component is com-

pletely locked in the subsequent boards or not.

Setting Z-threshold value

The Z-threshold value is used to evaluate whether the snap-in component is locked or not. The cur-

rent Z-axis position of every snap-in placement will be compared with its corresponding height ref-

erence position. If the difference between the two values is <= the set Z-threshold value in

SIPLACE Pro, the snap-in component is considered to be locked. If the difference is greater, the

snap-in component is considered not to be locked and an error message is displayed.

If the Z-value is too large, the machine can not detect an erroneous locking. If the Z-threshold value

is too small, the machine may stop often.

Depending on the component, you can start with the default value of 0.500 mm for the Z-threshold

and change this value successively in small steps.

Correct locking after a correct Z-threshold value has been set

1. Z-axis position = 0

2. Z-axis = reference position

3. Segment

4. Gripper

5. Snap-in component

6. Board

7. Locking mechanism

8. Support pin

Step 5: Station software

► If necessary, configure the inspection station

under Machine options – Inspection – If snap-in/

pin-in-paste confirmation is needed.

(Default: Inspect in output area.

When the board enters the output section, a detailed message is displayed.

The message contains:

●

The position of the board in the machine.

●

A list including all placement positions on the board which have to be confirmed.

●

A graphical board overview in which the selected items in the list are highlighted.

There are two options for each row in the list:

●

Component was placed correctly

The Z-height will be set as good for the snap-in detection.

●

Repeat measurement

The measured height will be ignored and the user has to confirm the height whenever the next

component is placed. The board keeps marked for inspection.

After setting the results for all placement positions, the settings have to be confirmed.
