7.1.2 View on Recognition Monitor

When the “P.E.C. RECOG TEST” display is opened, a recognition range (win-

dow size) appears on the recognition monitor.

Note: When a window size is changed, the captured image also changes on

the recognition monitor.

●

OK Result of Recognition

The X/Y beam moves to the place where a fiducial mark is located at the

camera center and the outline of the mark shape and crosslines are displayed.

The positional deviation (X and Y) of the fiducial mark from the camera

center and the recognition time (TIME) are displayed in the A-marked area

of the window.

(The displayed positional deviation shows the deviation detected before test-

ing.)

Note: The point of intersection of the crosslines is the camera center.

• NG (No Good) Result of Recognition

The outline of mark shape and crosslines are not displayed and the “RE-

SULT OF P.E.C. RECOGNITION” display appears on the touch screen,

showing the result of recognition as “NO GOOD”.

Ref.: Pressing the [RESULT OF RECOG.] key at the “P.E.C. RECOG TEST”

display (Fig. 4C250) also opens the “RESULT OF P.E.C. RECOGNI-

TION” display.

7.1.3 Procedure for P.E.C. Recognition Test

(1) Position the P.C.B. to be tested on the P.C.B. positioning section (P Con-

veyor).

• Open the “MANUAL TRANSFER OPERATION” display and posi-

tion the P.C.B. manually. (Hierarchical Sequence: “MANUAL MODE”

Display → “MANUAL TRANSFER OPERATION” Display)

• Confirm that each device is located at its origin.

(2) Set “CAM-A3” (Beam A) or “CAM-B3” (Beam B) in the “P.E.C. RECOG

CAMERA” data box at the “P.E.C. RECOG TEST” display.

When the camera is selected, the P.E.C. recognition lamp illuminates and

the specified camera captures the real image.

(3) Open the “X/Y BEAM MOVE”display (Fig. 4C258) and follow the steps

in “X/Y Beam Movement to Designated Position” to move the P.E.C.

recognition camera to the position of the P.E.C. recognition mark cap-

tured on the recognition monitor.

The parameters to be set here for “X AXIS POSITION” and “Y-AXIS

POSITION” must be the coordinates originated from the P.C.B. position-

ing reference point.

When the fiducial mark (recognition mark) to be recognized does not

enter into the window, open the “X/Y BEAM MOVE” (MANUAL

ALIGNMENT) display and move the camera (the X/Y beam) to the posi-

tion where the mark stays inside the window or open the “P.E.C. RECOG

TEST” display and enlarge the window size.

Note: The maximum size of the window is “10 × 10 mm”.

(4) Set various parameters for the P.C.B. recognition test.

(MARK TYPE, MARK SIZE, WINDOW SIZE, etc.)

• Select the key for which a parameter should be set.

The background color of the selected key becomes “Blue”.

• Use option keys or the ten-key pad to enter a parameter and press the

[SET] key. Option keys or the ten-key pad appears depending on which

data box is selected.

(Every time the [+] or [−] key beside the labels “GAIN” and “LEVEL”

is pressed, the set parameter increases or decreases one by one. It is not

necessary to press the [SET] key.)

(5) Select the [P.E.C. RECOG. TEST [MOVE]] key at the “P.E.C. RECOG

TEST” display and press the [MOVE] button. The P.E.C. recognition test

starts.

Check whether the recognition is normally completed or not.

Case: Recognition has completed normally.

• Display on Recognition Monitor

The camera (the X/Y beam) moves automatically until the fiducial mark

lies over the center of the crosslines while the result of the recognition

is being displayed at the bottom of the recognition monitor.
