5.16 IN and OUT Conveyor PCB Lifter

1. Lower the PCB lifter for the IN/OUT conveyor and adjust the lifter plate (after

loosening the mounting screws) to align with the center of the conveyor belt.

2. Adjust the clearance between the PCB detection sensor bracket and the plate shown below

between 0.5 to 1.0mm, by adjusting the cylinder rod end.

3. Move the IN and OUT carriers to the backward end position. Loosen the lifter plate mounting

screws and adjust so the clearance between the carrier claws and lifter plate is uniform.

at both ends of the lifter plate.

4. To set the lifter height, place a board on the In conveyor, open the carrier claws, raise the lifter,

close the carrier claws and lower the lifter. (The Pcb is now held by the carrier)

5. Raise the lifter when the carrier claw clamps the board.

6. Set a dial gauge on the board as illustrated (two gauges are recommended) Since the dial gauge

cannot normally read 1.2mm, use a 1mm feeler gauge when setting up the dial gauge before

raising the lifter. (Set 1 end first, then the other)

7. When the lifter is raised, the dial gauge should read 0.2 +/-0.1mm. If out of tolerance, adjust the

four bolts as indicated.

8. After adjustment, the lifter should raise the PCB off the carrier claws by 1.2mm.

9. For the lifter cylinder sensors, turn both the up and down end sensors ON first. Set the sensors

at a position 0.5mm further in towards the ON position.

10. Check sensor reaction in I/O
