(3) Checking of Attached Vacuum Nozzle

• After the vacuum nozzle is attached, rotate the rotary turret with the

cam hand-rotating wheel to let the nozzle pass over the dropped nozzle

detection plate. Check that the end of the nozzle does not touch the

plate. If it touches the plate, re-attach the vacuum nozzle.

The vacuum nozzle should be set in the descending mode

when it passes over the dropped nozzle detection plate.

(4) Nozzle Offset Teaching

Refer to “5.4 “Head/Nozzle” Tab” in “Section 6” of “Volume 2: Opera-

tion (Supervisor)” for details and perform teaching operations.

Wipe off dirt and dust on the end of a nozzle which was detected as

defective through teaching operation and then re-perform the teaching

operation.

Refer to “5.4 “Head/Nozzle” Tab” in “Section 6” of “Volume 2:

Operation (Supervisor)” for the items to be checked when a

nozzle is detected as a defective one through teaching opera-

tion.

When the machine operation is started with a defective

nozzle (detected by teaching operation) attached, the nozzle

is bypassed and not used.

1.4.5 Disassembly, Cleaning, and Lubrication of Miniature Stroke

Bearing

Note: Since the disassembly and reassembly work of the miniature

stroke bearings requires highly sophisticated technique, consult

our nearby service station for details.

• Cleaning Stage

Perform the cleaning when dirt has accumulated on the sliding part of

the shaft and the movement is hampered.

Perform the cleaning when dirt has accumulated on the hollow portion

of the shaft and the suction force has deteriorated.

Ref.: Clean the shafts once a year or so.

• Disassembly of Miniature Stroke Bearing

Disassembly Procedure

(1) Detachment of Head Assembly

(1-1) Loosen two M4L12 bolts (upper ones) and

two M4L16 bolts (lower ones) fastening

the head and detach the head assembly.

(1-2) Pull out the air hose.

(1-3) Pull the head forward to detach.

(2) Loosen three setscrews fastening the

diffusion plate and detach the plate from the

head.

Do not apply a wrench, etc., to the

magnet for head origin detection.

Otherwise, the magnet will be demag-

netized.

1.4 Maintenance Method

(3) Loosen two setscrews fastening the upper

part of the head and detach the holder from

the head.

Carefully loosen two setscrews be-

cause the holder pops out upward.

(4) Detach the miniature stroke bearing (MSB).

(4-1) Loosen and remove the setbolt and

detach the MSB plate.

(4-2) Detach the MSB shaft and the MSB outer

cylinder.

Pull out the MSB shaft from the upper

side. Use a pair of tweezers to pull out the

outer cylinder from the lower side.
