When the [COMP. RECOG CAMERA OFFSET] key is pressed at the “OFF-

SET DATA” display, the following display appears on the screen.

Every time the [NEXT PAGE] or the [PREV. PAGE] key is pressed, the next or

MAGNIFICATION 0.01µm/pixel X (Horizontal), Y (Vertical):

Used commonly for each camera

These parameters are used to set the magnification of the com-

ponent recognition camera in the increments of 0.01 µm per

pixel.

Parameters must be entered for both X and Y directions.

This offset data is automatically calculated through teaching

operation which is performed, using a jig component for mag-

nification measurement.

GAIN/LEVEL: Used commonly for each camera

These parameters are used to set amplifications at which the

signals of the image taken by the component recognition cam-

era is converted into the picture information representing bright-

ness.

Parameters are set as the offset values for camera reference

gain and level.

Normal Fixed Value: ±0

• The lower the gain is, the bigger the contrast becomes.

• The lower the level is, the brighter the whole view becomes.

SHUTTER SPEED 0.1msec

The set parameter represents the exposure time of the camera.

Up to 110 (= 11 ms) can be set in the case of the component

recognition camera.

Set parameters such that the same brightness is obtained for

“CAM-A1”, “CAM-A2”, “CAM-B1”, and “CAM-B2”.

• The bigger the value (shutter speed data) is, the longer the ex-

posure time becomes, making the captured image brighter.

When the [CAM-A1], the [CAM-A2], the [CAM-B1], or the

[CAM-B2] key (CAMERA POSITION) is pressed at the “COM-

PONENT RECOG CAMERA OFFSET” display, the following

display appears on the screen.

Every time the [NEXT PAGE] or the [PREV. PAGE] key is

pressed, the next or the previous page appears, enabling you to

set parameters for different cameras.

Common Items on Pages 1 to 4

BEAM A HEAD#1 X (Horizontal), Y (Vertical), Z (Angle):

Used commonly for each camera

The set offset data is used to adjust the positional and angular

deviations based on the design dimensions representing the

center (scanning coordinate center) of the component recog-

nition camera viewed from the P.C.B. positioning X/Y coordi-

nates (PL-XY: Origin P0). The values based on the PL-XY

coordinate system must be entered in the data boxes.

When the teaching operation is performed, the values calcu-

lated automatically using Head #1 on Beam A are saved and

used to figure out the placement correction values for Head #1

on Beam A.

• Design Values

CAM-A1

X: + 425.000 mm, Y: +496.000 mm

CAM-A2

X: + 317.000 mm, Y: +496.000 mm

CAM-B1

X: + 35.000 mm, Y: -130.000 mm

CAM-B2

X: + 143.000 mm, Y: -130.000 mm

When the camera scanning coordinate system deviates coun-

terclockwise from the P.C.B. positioning X/Y coordinate (PL-

XY) system, a plus value must be entered as “Z” (camera angle).

BEAM A HEAD#2 X (Horizontal), Y (Vertical), Z (Angle):

Used commonly for each camera

The set offset data is used to adjust the positional and angular

deviations based on the design dimensions representing the

center (scanning coordinate center) of the component recog-

nition camera viewed from the P.C.B. positioning X/Y coordi-

nates (PL-XY: Origin P0). The values based on the PL-XY

coordinate system must be entered in the data boxes.

When the teaching operation is performed, the values calcu-

lated automatically using Head #2 on Beam A are saved and

used to figure out the placement correction values for Head #2

on Beam A.

(PL-XY) system, a plus value must be entered as “Z” (cam-

era angle).
