Auto Width Adjust Conveyor Setup
Conveyor Edge Clearance Adjustment
If the conveyor edge clearance is greater than the SMEMA
standard of 4.75 mm or it is to be set to something other than
the SMEMA standard, follow the procedure below to adjust it.
Note that the preferred fixed position of the linear rails is at
3.5 mm but the clearance can be increased to up to 3.75 mm.
Also note that the maximum clearance is 4.75 mm (this includes
1 mm for the clamp). If trying to reduce the edge clearance any
further, consider carefully how much of the belt is left to carry
the PCB. Care should also be taken to set the top and bottom
side edge clearances such that they do not hinder board transfer
and clamping.
3.5 mm
Clamp
Belt
It is assumed that the clamp is 1 mm thick. When taking measurements
N O T E
the fixed straight edge of the conveyor rail is used for accuracy. When
re-checking the set distance, the clamp thickness is taken into account to
verify that the edge clearance conforms to the SMEMA standard.
The following procedure illustrates how to set a clearance of 3.5 mm. The
steps are the same when setting other clearances.
