6.1.3.2 Basic adjustment

(1) Adjustment of the distance between the transfer rails (Figure 6.1.3.1)

1) Mount the hand knob

to the handle shaft and turn the handle to set the

distance between the rails to the width of a PC board to be transferred +1

mm.

2) Move the PC board to be produced fully from one end of the rails to the other

end and make sure that the PC board can move smoothly on the rails.

3) When completing the adjustment, remove the handle knob and keep it on the

storage tray on the side of the machine.

WARNING

Before starting to work, turn off the power of the machine to avoid a risk

of injury caused by unpredictable activation of the machine.

(2) Adjustment of the centering pin (Omitted when the board outline is used for

reference) (Figure 6.1.3.2, Figure 6.1.3.3)

1) Turn off the power, and also turn off the air valve.

2) Loosen the M4 hexagon socket head bolts

used to fix the guide block

1 with the ball driver (supplied tool).

3) Move the stopper

⑪

by hand, and push the produced board (avoid the

center of the board and any cutouts of the board to contact the stopper)

against the stopper (as far as it goes).

4) Slide the guide block

in the X direction, and fit the centering pins

⑭

with the reference holes of the board. Allow a space of 0.5 mm between the

stopper

⑪

and the board. If the space is too small, the board may not be

set with ease.

5) While holding the guide block pushed to the guide rail

, tighten the M4

hexagon socket head bolts

to lock the guide block.

Notes:

①

Adjustment procedures 1) through 5) under (2) above can also be

adjusted manually by turning on the power and the air valve, and

using the independent control in the conveyor system of the manual

control and the automatic control.

②

When the centering pin is moved, be sure to reenter the position of

the reference pin for the machine setup. If it is not reentered, the

reference position of the data is made differently.

③

There is no need of adjustment for the board of same specifications.

④

Adjustment items 1) through 5) under item (2) above can be

performed by turning on the machine and using independent control

of transportation system, manual control or automatic control.

(See Chapter 9 " MANUAL CONTROL ".)

WARNING

Before starting to work, turn off the power of the machine to avoid a risk

of injury caused by unpredictable activation of the machine.
