9.1.1 Adjustment of Squeegee Head Height

••

• Rubber Squeegees

Adjustment Procedure

(1) Loosen the wing and stopper nuts.

Fig. 5A37-1

(2) Adjust the pushing distance by changing Dimension L (the dis-

tance between the upper end plane of the ball bushing and the

lower end plane of the stopper nut).

The pushing distance of the squeegee against the screen is set

to “1.0 mm”. (Factory-Adjusted upon Shipment)

When the stopper nut is turned once clockwise, the pushing

distance becomes shorter by 1.0 mm.

Turning the stopper nut once counterclockwise makes the push-

ing distance longer by 1.0 mm.

Pushing Distances Dimension L during Upward

Movement of Cylinder

0.5 mm 58.5 mm

1.0 mm 59.0 mm (Standard Setting)

1.5 mm 59.5 mm

(3) Open the “SEMI-AUTO OPN.” window (submenu) or the “Print

Block” tab sheet of the “MAN. SUB-SYS” window (submenu)

and push the squeegee against the P.C.B. located in the print-

ing section.

Refer to the above table and check the relation between Di-

mension L and the pushing distances.

9.1 Replacement of Squeegees

(a) When the rubber squeegees are worn out, the push-

ing distance becomes as short as they are worn out.

Therefore, it is required to change the rubber squee-

gees before the pushing distance is changed greatly

(in the range of 0.5 mm or less).

(b) The rubber squeegees can be ground to be re-used.

In this case, the total of the dimension (grinding) is

limited to “1.5 mm” (when the maximum pushing dis-

tance is “0.5 mm”).

When the total of the dimension (grinding) has be-

come “1.5 mm”, be sure to replace the rubber squee-

gees with new ones.

lower the location of the stopper nuts according to

the dimensions of the ground rubber squeegees (the

squeegees that have become shorter after grinding)

so that the same pushing distances can be kept.

9.1 Replacement of Squeegees

• Metal Squeegees with Holders (Incorporated with Holders)

Example : Permalex: PLX-A3060-270, PLX-A3060-350

When the metal squeegees are attached with the same

settings as the rubber squeegees, the clearances be-

tween the squeegees and the screen are changed in

the height direction because the blades are located at

the center of the holder thickness, making the push-

ing distances insufficient. Therefore, it is required to

adjust the pushing distances.

Adjustment Procedure for Spacer Use

(1) When spacers (thickness: 1.5 mm) are inserted as shown be-

low before the metal squeegees are attached to the squeegee

holders, the pushing distances can be kept to “1.0 mm” (same

as the rubber squeegees). (Squeegee Angle: 60°, Squeegee

Height: 30 mm)
