PCB alignment unit

These instructions describe how to install the following PCB alignment units: 2

00118526-01 / 00118525-01 / 00119426-01 / 00119425-01 / 00119678-01 / 00119677-01 /

2.1 Overview

This option is an additional mechanical stopper that may be needed for: 2

– PCB’s with a aspect ratio of 1:2 (length/width) or shorter

If PCB’s in landscape format (with the short side in moving direction) runs through the machine,

they

have too little lateral guidance and so they can twist a little. 2

This option aligns all PCB’s so that PCB fiducials are always

visible in the search window of the

PCB vision camera. 2

– For PCBs with cut-outs in moving direction:

On PCB conveyors for the existing machine platform, the mechanical stopper (HS-50 / S-25 HM

/ F

5 HM) stops the PCB in a different position than on the new conveyor with laser light barrier

(HS-60 / S-27 HM / HF-series / X-series / D-series). 2

This option ensures that PCB with recesses in moving

direction are always stopped exactly on the

same position on different PCB conveyor systems. 2

2.2 Description of the functions

The PCB is transported into the placement area until the laser light barrier is activated and the

PCB stops. As the first PCB moves in, the lifting table performs a reference run that determines

the PCB thickness. The lifting table then moves up until the PCB is still able to move with the

conveyor belt, and the ‘stopper PCB adjustment’ is level with the PCB. The PCB is then moved

with the conveyor belts against the PCB alignment unit, where it is aligned. Finally, the lifting table

is moved up so that the PCB is clamped and not in contact with the PCB alignment unit. 2

Once the placement process is complete, the lifting table moves the PCB alignment unit and the

PCB

down until the PCB can be moved onwards without interruption. 2

This operation extends the travel time by 0.5 seconds. This option is not taken into account by the

time optimization function.

An electrical switch signals the PCB alignment option to the conveyor control. The station software

outputs a warning message to the operator during the width adjustment process. 2

: The PCB alignment unit must be set manually by the operator.

The maximum component height on the underside of the PCB is still 40 mm. 2
