5. Algorithm: Special 4 (Component consisting of multiple sections)
Finds the center of each side and finds the component tilt from the lines joining those side centers.
Algorithm can be used when there are leads on the bottom only, left only, right only, top and
bottom, left and right, top and lower left, top and lower right, upper left and right, lower left and
right, top bottom left and right.
Several methods can be selected to find the component center.
When Option 2 is 0, the center of a circumscribed rectangle is taken as the component center.
When Option 2 is 1, the rectangle center found from lines running from the center of each side is
taken as the component center.
When Option 2 is 2, the average center point of the detected leads is taken as the component
center.

Vision Option 1 Set to 0.
Vision Option 2 Set to 0.
Vision Option 3 Set to 0.
Vision Option 4 Specify a numeric value representing the Cut Inner Noise
and Cut Outer Noise levels, and also the sequence to
execute them. For example, when the Cut Outer Noise
level is set as n1 and the Cut Inner Noise level is set as n2,
set a value of "n2 × 8 + n1" here. When executing in the
sequence from Cut Outer Noise to Cut Inner Noise, set a
value obtained by subtracting 128 from "n2 × 8 + n1".
Lead Group N Set the number of lead groups (1 or 2).
Lead Number N1 Set the number of leads.
ReflectLL N1, Lead Width N1 Set the size (surface area) of the upper lead section. If a
rectangle, specify a value of the lead length multiplied by
the lead width. If a circle, specify the diameter of the circle
with the lead width and a lead length equal to 0.
Lead Pitch N1 Set the pitch of the upper lead section.
Find PosX N1, Find PosY N1 Set the center-of-gravity position of the upper left lead
section.
Lead Number N2 to Find PosY N2 Set the group 2 data when the number of lead groups is 2.
Set 0 when the number of lead groups is 1.
Lead Group S Set the number of lead groups (1 or 2).

2.2.5 Special rectangle (Sp. Quad) recognition mode
Rectangular and square shaped components can be recognized with this algorithm.
1. Contour edge detection
Extracts the contour of the component.
2. Detection range setting
Sets the respective detection range on the top, bottom, left, right on the detected contour. Which
edge (top, bottom, left or right) to detect can be selected by making a parameter setting.)
3. Application of line
Applies a line to the edge coordinates within the range that was set. This process is run for all 4
directions. (Finds a line according to which edge (top, bottom, left or right) is being detected.
4. Component center and tilt detection
The tilt of the 4 lines that were found is averaged and taken as the component tilt. The center-of-
gravity of the edge being measured is the component center. (The tilt is found with the correspond-
ing method for whichever edge is being measured {top, bottom, left, right}.
