Figure 15: Z-Axis Rack Gear Assembly
Adjusting the heater head height (figures
13 and 14):
The Z-Axis adjust handle (1) is attached
to the heater head. It is used to select the
rough position of the heater head (7).
This position is either UP or DOWN.
Squeezing the adjust handle disengages a
pin from the Z-Axis fine adjust rack gear
assembly (3), allowing the head to be
lifted or lowered to the top (4) or bottom
(5) travel stop. There is a slot in the rack
assembly at either end of travel in which
the pin engages when the adjust handle is
released. The Z-Axis Fine Adjust Knob
(2) rotates a pinion gear (6), which moves
the rack assembly up or down. This
provides additional up and down
adjustment of the head when it is in either
the UP or DOWN rough position.
During general use the rack assembly
should always be adjusted UP using the
knob, unless the operator is in the process
of picking, placing or soldering a
component. This ensures that there will
be adequate clearance between the heater
nozzle and the board or nest when a rapid
move is made between the UP and
DOWN rough positions.
