5.4 Adjusting the waste tape cutter

Warning: The Waste tape cutter plate is an extremely heavy item. Please handle with

care. Also, take extreme care when handling (or working in the vicinity of) the cutter

blade. It may cause damage or personal injury.

1. Remove the MFU, and the waste tape cutter cover.

2. For the waste tape cutter cylinder air valve speed controller adjustments please refer to

the following table:

Speed Controller Air Tube Line Number of turns from fully closed

Cutter close valve U5 7.5

Cutter open valve U6 8

Cutter engagement adjustment

1. Ensure the gap between the movable cutter and the fixed cutter is within 0 ~ 0.03 mm,

when both cutters are engaged.

2. Ensure there are no nicks or cracks in the cutter blade.

Stopper position adjustment

1. Position the stopper just at the end of the cylinder stroke.

2. Lock the stopper 1.5 ~ 2.0mm in from this position.

Retract limit sensor adjustment

1. With the stopper positioned, adjust the sensor so that when the cutter is moved to its

retract limit the I/O X031 Side1TpCutOrgPos comes on 1.5 mm in from the cylinder

stoke end.

Lubrication

1. Lubricate the sliding parts of the link arm (cutter) and LM rail.

Waste tape duct height adjustment

1. Attach the waste tape duct and temporarily tighten it.

2. Load a feeder on the device table and set the Y direction clearance between the feeder

and the waste tape duct to 12.5mm. Please see the diagram below:

3. Set the height of the waste tape duct so that it is around 1mm higher than the feeder

upper surface. There should be sufficient clearance for the waste tape to feed down the

duct into the waste tape box without getting stuck.

4. To confirm that the waste tape duct is not skewed, check that the clearance and height

are the same at slot numbers 1 and 40.

5.5 Adjusting the nozzle/parts vacuum pressure sensor

Jig: Nozzle jig (Z9531DEPJ0070)

Measuring equipment: Manometer, (PG-100-02VH).

1. Refer to the picture above and turn the nozzle air blow speed controller 5 times from fully

closed and lock.

2. Enter I/O Y021 NozzleUnhold and adjust the blow time throttle so that the air blow is ON

for 2 seconds and then cuts out. Once the blow time is adjusted correctly, lock the

throttle.

Vacuum sensor setting

1. Switch both vacuum sensors from [MEAS] to [SET].

2. Adjust the “set” volume dial on the side of the sensor until the sensor displays the

following values:

Sensor Position Value

Nozzle Vacuum Sensor Top Sensor -20

Parts Vacuum Sensor Bottom Sensor -35

3. Once the values have been set switch both vacuum sensors from [SET] to [MEAS].

4. Turn I/O Y021 NozzleUnhold OFF when the nozzle jig is attached. The nozzle vacuum

sensor should show a value of –70Mpa or more negative.

5. Turn I/O Y020 PartsPickUp ON. The parts vacuum sensor should show –70Mpa or more

negative, when a part is vacuumed.

6. Attach the manometer to the nozzle jig. Turn Y021 NozzleUnhold OFF, and attach the

nozzle jig to the placing head. Turn I/O Y020 PartsPickUp ON. Under these conditions

the manometer should indicate the vaccuum pressure is –600mmHg (-79.99kPa) or more

negative.

7. Finally adjust the parts air blow speed controller. Turn Y01D PartsPickUpDes ON, and

Y020 PartsPickUp OFF, then adjust the speed controller until the manometer indicates

the air blow pressure is +50 mmHg (6.67kPa).
