3.7 Automatic Offsetting of Pickup Position

For reasons such as variation in part position and nozzle bend, a part may not be

centered on the nozzle when picked up. The machine has a function that can be used to

automatically offset X- and Y- pickup positions to stabilize pickup.

If the part data item [Pick-up Auto Offset] is set to [0: Yes], then pickup position offsets

are calculated based on vision processing results, and subsequent pickups of the same

part are automatically offset.

Pickup Auto Offset Edit

The offset distance can been seen and edited at the [Pickup Auto Offset Edit] screen.

At the [Production] screen, select [Pickup Auto Offset] to open the [Pickup Auto Offset

Edit] screen. The commands at this screen can be used to see and edit the offsets.

[Close] button

Select this button to exit the [Pickup Auto Offset Edit] screen. A dialog will then appear

reminding you that the offsets will be saved.

[Previous Page] button

Select this button to return the display to the previous page.

[Next Page] button

Select this button to advance the display to the next page.

[Save to File] button

Select this button to save all pickup offset data to an MS Excel format file.

Notes:

• If a pickup offset data file already exists on the floppy disk, an overwrite confirmation dialog

appears.

• If a pickup offset data file already exists on the floppy disk and the file is protected, an error

message will appear.

[Offset Clear] button

Selecting this button will reset all of the offsets to 0.

When this button is selected, a confirmation dialog appears before the offsets are reset.
