15.2Cleaning the Fluorescent Disk (Once a Month)

If dust or other fine particles build up on the fluorescent disk, the

percentage of UV light reflection from the station 4 UV lamp will be

reduced. If this reflected light is insufficient, a proper image can not be

captured during vision processing. Vision processing errors thus occur

and placing performance drops. If a certain nozzle consistently causes

pickup errors, clean its fluorescent disk with a soft brush (the type of

brush used for cleaning a camera lens is best). Do not rub the fluorescent

disk with a rag. Rubbing the fluorescent disk makes grime cohere to the

sheet, which causes vision processing problems.

If grime cannot be removed, replace the fluorescent disk.

15.3Cleaning the Shaft (Once a Month)

Shaft movement slows if grime and lubricant collects on it. If the shaft

does not move fast enough, vertical movement during the placing

operation is adversely affected and placing performance drops. Clean the

shaft and holder with a dry cloth. Refer to figure 15-2 below.

Note: Do not use kerosene, thinner or alcohol based solvents as these will damage

the holder.

15.4Cleaning Out the Waste Tape Box (Every 8 Hours)

Tape cut by the waste tape cutter travels through a tube to the waste tape

box. Empty the waste tape box every eight hours, as a large amount of

waste tape collects after eight hours of production. When cleaning out the

waste tape box, check the filter above it, and, if necessary, clean the filter

with a vacuum cleaner.

15.5Cleaning the Tape Suction Path (Every 8 Hours)

After the end of the tape is cut off by the cutter, it is drawn into the

suction path in the course indicated by the arrows. If this area becomes

blocked by waste tape, tape feed will be impeded and part pick-up will be

unreliable. Inspect this area for blockage if tape feed abnormalities cause

pick-up errors during automatic production.

Under normal operation the tape suction path should be cleaned out

every eight hours.

15.6Cleaning the Prism Surfaces (When Replacing Tape)

Oil or dirt on the surfaces of the prisms can lead to problems such as

reduced light strength and distortion of the image. Wipe the prism

surfaces clean with clean gauze once a week.
