2) Determining whether the PCB photoelectric sensor works normally
The equipment is equipped with a photoelectric sensor at the rail inlet end, the left
baffle cylinder, the right baffle cylinder and the outlet end respectively. Under normal
conditions, when a PCB passes through the rail, the signal lamp color will changes.
3) Determining whether the mechanical limit switch works normally
There is a mechanical limit switch at the end of the X axis and Y axis of this equipment,
which can be checked and confirmed by multimeter. Under normal conditions, both
ends of the connecting line are in conducting state. When the axis runs to the end, the
mechanical limit is pressed to disconnect both ends of the connecting line. If the
mechanical limit switch is damaged, a spare part installed in the side-by-side position
can be used for replacement.
4) Lubrication and maintenance of screw rod and guide rail parts
Screw rod and guide rail are the main transmission components of the equipment
operation. Their maintenance is the most important part to ensure the transmission and
positioning accuracy of the equipment. During the annual major maintenance, special
attention should be paid to removal of old oil and dust and application of new oil. It is
recommended to use the German super lubricating grease OKS-422. The specific
operation steps are as follows:
Step 1: use cloth strips to wipe off the old oil on the screw rod/guide rail.
