g) If the placement accuracy results exceed the allowable tolerance ranges then carry out

calibration (Center_Offset, Final_Offset).

h) Add the Center_Offset X and Y and Final_Offset X and Y values to the original value and

then directly enter the values at the machine using the following command operation.

[PROPER], [CAMERA], [ETC], [ETC], select [Center_Offset] or [Final_Offset] for input, use

the arrow keys to select X or Y, input the value and then hit return.

<<How to obtain the input values>>

A total of eight 60-pin glass parts are placed as shown in the figure above.

The glass board and parts form a vernier scale (1 graduation is 0.005 mm).

Measure how many graduations the conforming location (location where the 4 leaded

sides of a part match the pattern) deviates from the pattern center.

Center_Offset X and Y are obtained by (0 degree’s value – 180degrees’ value) / 2.

Final_Offset X and Y are obtained from the average value of all placed parts.

The sign of the input values for Center_Offset X and Y as well as Final_Offset X and

Y are obtained from the previous input value sign table.

i) After the values are input, place the parts again in automatic operation (step 5), and carry

out measurement to obtain accuracy within the allowable tolerances.

j ) If the placement accuracy falls within the allowable tolerance ranges then input the data

into a QP242E Camera 6 Placement Accuracy Table (Excel file: QP242E camera6placement

accuracytable.xls) and obtain a printout of the table.

4) Results Tabulation

Once the placement accuracy of each camera type falls within the allowable tolerance

ranges, use the DT to carry out placement accuracy measurement six times (total of 24

points) in succession without changing the Proper data.

From the results enter the Measuring point deviation {X, Y, Ang (Q)} data in the

placement accuracy table (Excel file: Cameraaccuracystatisticstable.xls).

・ For camera type 1 since 32 points can be measured at one time, measurement does not

have to be repeated six times. One measurement (total of 32 points) completes the process.

・

For camera type 6 since eight points can be measured at one time, measurement is

completed after three rounds of measurement. For camera type 6 two glass parts are used

for each angle of the part.

Does not have to be input since the

values are entered automatically.

Be sure to record the control number.

Results of measurement

using the DT for camera type

2, 3, 4, and 7

Input the deviation (number of

graduations). All other items are

calculated automatically and thus

do not need to be input.

Input the module No.

Enter this value in the placement

accuracy table created in the next

step 4).

Note: The Q value must be

converted into 1/1000 deg.

[CHAPTER 8]

MTU6 Adjustment

Note: Cut the power to the machine before connecting the MTU. If the by-pass key is

inserted in the mechanical switch of the MFU specifications safety door, remove

the key and put it in the MTU cover. If the key is left inserted in the MFU

specifications switch this will disable the MTU front safety door by-pass key

which can lead to damage.

[8-1] Prior to Adjusting the MTU6

- Since layered stacking of trays is not possible on the MTU6, the number of part types that can be

loaded increases to between 50 and 100 types in comparison to the MTU7 (MTU7 can handle from

10 to 20 part types).

- On modules that use the MTU6 it is possible to switch from an MTU6 to MFU and vice versa.

When changing from an MTU6 to an MFU, safety fence replacement work is also included. Check

the specification manual and be aware that if this option is included a spare fence will also be

shipped. When an MTU6 is installed on an MFU module, in some instances Proper data

measurement will be necessary.

- When an MTU6 unit is connected to the machine, it must be connected with the machine in the

zero set complete status. Also verify that the shuttle jaw and tray holder do not interfere with each

other.

- When disengaging an MTU6 unit from the machine, separate the shuttle jaw and tray holder and

also verify that the shuttle is advanced forward before beginning work. The shuttle may be

damaged if it is at the retract limit. (Remove after carrying out the magazine replacement

command operation [POSITION], [MTU], [EXCHG MAG.], and press START.)
