2.10.1. Flying Vision
2.10.1.1. Overview
The flying vision system is a vision system attached on the head that recognizes a
component when it moves from the pickups position to the placement position. 6 CCD
cameras attached on the head recognize components on 6 heads simultaneously. 3 types
of multiple step digital lights can be selected for each head.

2.10.1.2. Light Path Control
The flying vision system has a mirror on the light path. To avoid a collision with the Z
axis, it rotates during pickups, recognition, and placement.

Figure 2-12. Light path control
During component pickups, the mirror attached on the head rotates and moves to the front
of the head. When the component is on the move to the placement position after it has
been picked up, the mirror rotates and moves to the bottom of the head, and the image of
the component is formed through the mirror on the CCD camera attached on the head.
The image is vision treated and the position and angle of the component is recognized. By
using the recognized position and angle of the component, the coordinates of placement
position are adjusted. When the component is placed on the adjusted position, the mirror
rotates and moves to the front of the head again.

2.10.1.3. Illumination
The flying vision system provides 3 types of lights for each head.
Figure 2-13 Illumination
2.10.1.3.1. Side Light
The side light is a light illuminating from the side of the component. This light is installed
on a lighting system that moves to the Z axis. When it is not in use, it stays up, and when
a component is recognized, the device comes down and illuminates the component. This
light is used to illuminate the ball during BGA component recognition, and it is also used
to emphasize the outline of Chip and IC components. It is possible to control steps
between 0 - 15.
2.10.1.3.2. Outer Light
The outer light is a light illuminating obliquely from the front of the component. This
light exists between the lens and the mirror of the CCD camera and it illuminates the
entire component. It is used for most components and it is possible to control steps
between 0-15.
2.10.1.3.3. Inner Light
The inner light is a light illuminating straightly from the front of the component. It exists
right in front of the CCD camera lens, it is used for components that cause a lot of
reflection. It is used for odd type components such as connector and it is possible to select
