Chapter XII Repair and Maintenance of
Equipment
12.1 To ensure the normal operation of the equipment and prolong its service life, please perform
the following regular maintenance work:
a) At the end of the day, turn off the power supply of the computer and equipment, and suck
the dust on the equipment table surface with a vacuum cleaner. If there is no vacuum
cleaner, dry towel can be used to wipe off the board dust and the like from the bench
surface. Note: do not blow the surface with an air gun. The dust and debris will be blown
into the top of the equipment and will attach to the screw rod, guide rail or lens, which will
affect the accuracy and service life of the equipment. If metal debris is blown into the
electrical appliance, there may be short circuit and fire.
b) Wipe the dirt on the equipment surface with towel. Note: do not use organic solvent
(such as board washing water) to wipe the surface of the equipment, otherwise the paint on
the surface of the equipment will be damaged.
c) Maintain the screw rod and guide rail every month. Clean the old oil with clean white
cloth, and then evenly brush the oil on the surface of the screw rod and guide rail with No.
10 or No.11 oil brush. Note: grease and lubricating oil must be of good quality. Otherwise,
the surface friction on the screw rod or guide rail will be increased, thus shortening the
service life of the screw rod and guide rail and affecting the accurate positioning of the
machine. Recommended: Germany OKS Super Grease OKS422, or referring to the grease
used in mounter maintenance.
d) Clean the filter cotton on the left side of the industrial computer panel every 1 month.
Note: filter cotton should be dried after cleaning and then put back in place.
e) Check the light source every 3 months. Since the brightness of LED lamps may change
slightly after half a year, the light source needs to be inspected once to ensure normal
inspection.
f) Calibrate the camera every three months. Since the camera keeps moving every day, it is
necessary to check whether the camera screws and lens screw are fixed properly and
whether the calibration value is within the acceptable range.
12.2 Detailed inspection process of each component
1) Determining whether each groove-shaped photoelectric sensor works normally
There is one X-axis and one Y-axis on this equipment, and there are two groove-shaped
photoelectric sensors in the width direction of the track. If paper is put into or taken out
of the groove, the signal lights will normally be on or off.
