1.2.4 Head-related unit: parts identification
The head unit consists of the laser align sensor used to detect placement and angle
offsets of the component, and the Z slide shaft which can be moved up and down, or
be turned.
The Z slide shaft and the Z slide bracket of the Z axis are driven with rotations of the
ball screw.
The θ-axis encoder located on the upper section of the θ-axis motor detects the angle
of a component.
The machine is equipped with two units of FMLA head (L) and FMLA head (R) as
standard parts.

1.2.6 Nozzle
(1) Select the nozzle from No.501 through No.508, according to the shape and size
of the components to be mounted.

(2) Nozzle selection
The nozzle can be automatically recognized if you follow the explanation of "3.4.1
ATC Nozzle Selection". If you manually select the nozzle, select the nozzle with
extreme care to prevent poor pickup and placement of a compornent.
The nozzle numbers for major types of components to placed be are shown in
Table 1.2.6.2. However, to keep accuracy of pickup and placement, select the
appropriate nozzle No. by referring to the minimum size of the suction area of
each component.
See the item (3) for the minimum width (D) of the sucked area of each
component.
