STU Adjustment & Operation Check

[10-1] Prior to Adjusting the STU

STU-1 Specifications

Number of part types : 1 type per unit

Tray size : 100 x 150 mm ~ 150 x 330 mm

Tray stacking height : 4 ~ 50 mm

Max Empty Tray Weight : 240 g/tray

Occupied devices : 9 devices

Number of units that can be loaded: MFU-5 1 (0) MFU-58 2 (1)

- The values in parentheses indicate the number of STUs that can

be loaded on an MFU when a 2-camera system is used.

STU-2 Specifications

Number of part types : 1 type per unit

Tray size : 50 x 50 mm ~ 102 x 102 mm

Tray stacking height : 4 ~ 50 mm

Max Empty Tray Weight : 240 g/tray

Occupied devices : 7 devices

Number of units that can be loaded: MFU-5 2 MFU-58 4

- There are no restrictions when a 2-camera system is used.

- The STU able to stack trays and for this purpose is equipped with a unit to raise trays and a tray

remover.

- Trays are always positioned with a top surface reference using the positioning sensor. As a result

part pickup using the pickup nozzle does not have to take into account such things as the part

height, tray thickness, and number of trays depending on the pickup nozzle.

- Since STU units can be loaded on an MFU it is possible for a mix of STU and IP-type feeders to be

loaded on a module. However, it is not possible to load two different types of STUs on the same

module since this would create two STU mechanical standards.

- Since there is spacing (3 device positions) on both sides of the STU to avoid interference with IP

feeders, it is recommended that the STU be loaded on the left side of the MFU and that an

accompanying reject parts conveyor be loaded on the right side of the STU.

- An independent air source is required on the STU.

[10-2] STU Loading

1) Cut the power to the machine.

2) After checking the STU type and module specified for loading in the specification manual, set the

STU in the MFU (D9). Also connect the STU coupler connector part request cable to the device

number 9 connector and the tray out cable to device number 8.

3) Load the MFU in the machine being careful of the cables. After the MFU is loaded, connect the

STU power cable and air tubing.

4) Once the cables are connected turn the power to the machine on and verify that the [POWER ON]

lamp on the rear of the STU is lit

[10-3]

Proper Data Check

After checking the following Proper data items transmit the Proper data to the machine and

then reboot the machine.

Module Proper data

* PLM? Device Type

0: Recognize IP type feeders

* PLM? STU_Type

0: Compatible with a Y-direction length of up to 250 mm (STU2)

1: Compatible with a Y-direction length of up to 330 mm (STU1)

* PLM? IPDO_X, Y, Z

Go to section [6-24& 25] and enter the measured values.

When entering the Proper data items above, if Package_Type in the Package_Edit data of the

placement part is set to “0”, the machine will recognize parts supplied from an STU.

[10-4]

Tray Positioning Side Plate Parallel Measurement

1) Set a dial gauge on the placement head, move in the Y-direction and measure the side steel plate.

Tolerance: Within 0.5 mm

2) Set the dial gauge in the same way, move in the X-direction and measure the front steel plate.

Tolerance: Within 0.3 mm

[10-5] Tray Position Check Sensor & Add Check Sensor Adjustment

1) After connecting the STU cable and air tubing, the STU power will come on when the machine

power is booted up.

2) Adjust the tray position check sensor and add check sensor light beams so they are aligned at the

provisional heights by loosening the sensor mount hollow bolts and moving the sensors up and

down. Check the servo amps while doing this. Temporarily adjust the sensors so that the height

of the add check sensor is higher than the tray position check sensor.

3) Load a standard 100-pin size empty tray (used when acquiring data) on the STU tray holder and

then load the device jig used for Proper data measurement next to the STU at device position

number 11.

4) When the I/O Y02D SEND PART D9 of the loaded module is turned on, the tray holder rises, the

top of the empty tray set in the previous step is detected by the tray position check sensor and the

holder then stops.

5) Move the sensor up and down to adjust it so that the height at which the holder stops is the same

height as the Proper data IPD0_Z height measured in section 7.22. Use the adjacent jig and a

scale to check the height as it is adjusted.

6) After the height of the tray position check sensor is adjusted, load a 2 mm thick board on the top

of the empty tray. Adjust the sensor height so that this board is detected by the add check sensor

but so that the Fuji standard 1.6 mm thick board is not detected.

[10-6] Tray Existence Check Sensor Adjustment

1) Lower the empty tray that was loaded in the previous section and then load a 2 mm thick board

on the tray holder.

2) Loosen the tray check sensor dog attached to the bottom of the STU and then move the dog to a

position where the sensor will not come on even if raised when there is no tray.

3) Turn the I/O Y02D SEND PART D9 on and raise until the top of the 2 mm board is detected by

the tray position check sensor.

4) At the position where the top of the board is detected, use the dog that was loosened earlier to

adjust the tray check sensor so that it comes on at the same time.

5) After adjustment is completed, remove the board, set the I/O SEND PART D9 on with no tray on

the holder and then raise the holder.

- After the tray holder rises to the tray position check sensor, if the sensor determines that no tray

exists and then descends this completes adjustment of the sensor.

- If the tray holder does not descend but stops at the tray position check sensor position then the

tray check sensor must be adjusted again.
