Note 1: When the back light is used to recognize a lead, the lead looks thinner because completely
parallel light is not used.
For some area of the field view, the light illumination from the bottom is used as the back light
with being reflected onto the background plate of the head. Therefore, the lead looks further
narrower when it is positioned in the area lighted with the light from the bottom because the light
is reflected to the lead surface. In some case, the lead cannot be seen at all. As a result,
recognition of a lead with the back light is not guaranteed.
Note 2: The area to be recognized of the maximum-sized component shall be within the field view of □52
mm of a VCS including the component placement position error and a teaching error caused
when the component is picked up.
For the maximum size of the image recognition, the pick-up XY error shall be ±1 mm or less and
the angle error shall be ±3°or less.
When the image recognition applies to components with a size of more than □7 mm, the
components cannot be allocated to adjacent heads.
When a component is recognized with the back light, and the position 1.3 mm or less far from the
edge of the component is picked up, the shadow of a nozzle may prevent the component from
being recognized stably.
Note 3: The pitch of a general-purpose vision component type of lead component (multi connector, etc.)
and ball component that can be recognized in the follows.

not displayed normally), use a VCS (10-mm field of view camera) (optional).

(2) Component height
The component height specifications of the RS-1/1R differ from those of the conventional
machine.
The height of the placeable component is changed by controlling the LNC120-8 unit position in
the Z-direction.
This shortens the distance between the pickup/placement position and LA surface and achieves
the improvement of the pickup-LA recognition-placement tact.
The position and movement axis of the LNC120 unit are determined to the ZA height and
ZA-axis, respectively.
The ZA height reference is the bottom surface of the LNC120-8 unit.
Additionally, the ZA height is not stepless and is set to several classes as shown below according
to the applicable component height.
Table ZA height classes
Class
Height of applicable component
1 [mm]
More than 0 [mm] and 1 [mm] or less
3 [mm]
3 [mm] or less
6 [mm]
6 [mm] or less
12 [mm]
12 [mm] or less
20 [mm]
20 [mm] or less
25 [mm]
25 [mm] or less
The XY-axis movable height has a margin of 3 [mm] in a class other than 1 [mm] class.
Components applicable to 1mm-class has a margin of 2 [mm].
Additionally, the distance between the bottom of the LNC120-8 unit and the LA surface is 5 [mm]
in each class.
