3.10 Back-up Plate Height and Flatness Adjustment

1. After zero-setting the Z-axis, raise the table to 5000 pulses. Place the height

adjustment jig on the backup plate.

2. Adjust the 4 bolts so the top surface of the jig and clamper base are equal.

3. Note: When changing the Z-axis position, the spring force to the plate changes

and the jig’s height will slightly differ. Please pay attention when adjusting.

(Adjust it within range so that the Z-axis and backup plate are synchronized.)

4. Flatness tolerance ----- less than 0.1mm

(There are 4 adjustment bolts. It is better to set one height as reference and measure with a

dial gauge.)

3.11 Back-up Pin Interference Prevention Sensor Adjustment

1. Adjust the 4 flags so the sensors will turn ON, when the clearance between the Y-table and the

backup plate is 2mm. (Set the flags so the 4 sensors activate within 50 pulses of each other.)

2. Check the sensor reaction in I/O.

3.12 PCB Set Check Sensor Adjustment

1. Adjust the sensor BKT so that the light axis comes to the center of the reference pin

and secondary pin block hole.

2. Set the sensor so it turns OFF when both the reference and adjustable pins move down

1.0 to 1.5mm.

3. As for the adjustable pin, the sensor should react at maximum, mid and minimum

pitches. Make sure that the green LED is always on.

4. Check the sensor reaction in I/O

3.13 Main Conveyor PCB Clamping Claw Check and Adjustment

3.13.1 (Part 1) Claw Positioning Adjustment

1. Check that the reference pin switch valve is set to “Mark Ref”.

2. Lock the rail-clamping claw at the closed position by solenoid valve.

3. Check that all the individual claws are loose.

4. There is some play in the position of the rail-clamping claw center bracket, so check that this is set

at the center of the play.

5. The next step is to lock all the individual claws. When these are locked, the clearance between the

tip of the claw and the guide rail should be in the range of 0.03 – 0.10 mm. (A) Each claw should be

locked using a 4Nm torque wrench. However, before proceeding to lock each claw, there are some

other considerations to bear in mind. Refer to figure 25.

6. Proceed to lock each claw making sure that the clearance values are within the ranges shown

above. It may be useful to lock the two center claws and the two claws at both ends of the rail first,

then proceed to lock the claws in between. Remember that clearance between the tip of the claw

and the guide rail should be in the range 0.03 to 0.10 mm. The claw is attached to the rail by two

3mm bolts. Tightening the top bolt will increase the clearance, tightening the bottom bolt will

decrease the clearance.

3.13.2 (Part 2) Claw Float Adjustment

1. Set the reference pin switch valve to “Pin Ref”.

2. Place a 4mm thick PCB in the main conveyor clamper.

3. Activate but do not lock the adjustable rail clamping solenoid.

4. At this position, there should be 0.5mm clearance between the clamper claw tips and the PCB.

5. Use the adjusting bolt on the claw float cylinder to set the clearance at 0.5mm. Note that the

clearance will vary slightly at different points on the clamper rail. Set the 0.5mm clearance at the

narrowest point.

6. On the fixed rail side, set the position of the clamping claw float sensor flag so that the sensor LED

is OFF when a 4mm thick PCB is clamped and ON when a 4.5mm PCB is clamped. Note that the

clamping solenoid should be activated but not locked for this adjustment. I.e. In this case “clamped”

means press the clamping solenoid once but do not lock it. Note: the sensor is Dark-On so when the

LED is Off the I/O input is ON, and vice versa. I/O: (X032 PCB Set CLP OK).

* Note that 0.5mm clearance on both sides is the ideal. However, this may be difficult to

achieve. In such cases a rough balance between the two is acceptable.
