6.6 HEAD OFFSET (GET BOTH IMAGE) Display

• This display enables you to teach the head position offset for the simulta-

neous image capture operation, indicating where the head rotational center

of the subordinate head is located in comparison with the center of the con-

fronting camera when the component recognition function (simultaneous

recognition function) is implemented with components being picked up by

the right and left heads.

Calculate the offset value by recognizing the pattern of the printing to the

teaching jig component plate (component recognition offset jig) which picked

up with the nozzle with the component recognition camera.

Note: Follow the teaching procedures in the specified order. Otherwise, some

trouble (such as inaccurate component placement, frequent mechani-

cal errors, etc.) will arise.

When the [HEAD OFFSET (GET BOTH IMAGE)] key is pressed at the

“TEACH OFFSET” display, the following display appears on the screen.

Note: Handle this fragile jig very carefully.

• Two types of patterns are printed through vapor deposition on the glass for

positional calculation.

*1 [ALL BEAM] Key

The machine performs the teaching operation of the head

position offset for simultaneous image capture operations

at both Beams A and B.

When this key is selected and the [MOVE] button is pressed,

the machine starts the teaching operation.

Note: Before performing the teaching operations, zero

both beams.

It is calculated through the procedures similar to the teach-

ing operation of the head rotational center offset data where

the head rotational center is located when viewed from the

camera center in comparison with the camera positioned as

the subordinate head during simultaneous recognition for

each individual heads.

*2 [BEAM-A] and [BEAM-B] Keys

The machine performs the teaching operation of the head

position offset for simultaneous image capture operations

at Beam A or B.

When the [BEAM-A] or the [BEAM-B] key is selected and

the [MOVE] button is pressed, the machine starts the teach-

ing operation.

Note: Before performing the teaching operations, zero

both beams.

*3 [HEAD #1] and [HEAD #2] Keys in “BEAM-A” Group

Box and [HEAD #2] and [HEAD #1] Keys in “BEAM-B”

Group Box

When one of the above-described keys is selected and the

[MOVE] button is pressed, the machine starts teaching the

offset data related to the selected head #.

Note: Before performing the teaching operations, zero

both beams.

Reference

Subordinate Head:

When two steps are paired through the simultaneous pick-up or the pick-up priority function

designated in the placement data, this head handles the component related to the step No. larger

than the other. On the other hand, the head which handles the component related to the smaller

step No. is called "Guide Head".

The simultaneous recognition is automatically prohibited and images are captured individually

when;

• components which require BGA lighting are picked up.

• a value other than "0" (zero) is set (designation of eccentric pick-up) in the "X" and "Y" data

boxes of the label "PICK-UP LOCATION CORRECTION" at the "CMPNT LIBRARY"

display.

• the visual field of the confronting camera cannot cover the components picked up by the right

and left heads.

In these cases, the beams must be moved such that the rotational centers of the heads are located

at the camera centers before the images are captured.

Compared with this, in the case of the simultaneous recognition, the guide head (for the smaller

step) moves normally but the subordinate head faces the other one at the position where the head

rotational center does not match the camera center due to the relation between the head-to-head

and camera-to-camera pitches. Therefore, this offset data is required for recognition processing

and correction calculation.

*4 [ALL BEAM HEADS ZERO [MOVE]] Key

Both Beams A and B are zeroed.

When this key is selected and the [MOVE] button is pressed,

the zeroing operation starts.

*5 [GAIN･LEVEL] Key

When this key is pressed, the “GAIN･LEVEL” display (Fig.

4C70) appears on the screen.

These parameters are used to set amplifications at which

the image signals of the image taken by the component rec-

ognition camera is converted into the picture information

representing brightness.

Parameters are set as the offset values for camera reference

gain and level.

Normal Fixed Value: ± 0

• When “ENABLE” is set in the “DESIGNATE” data box,

be sure to set parameters in the “GAIN” and “LEVEL”

data boxes.

The set parameters are used for P.E.C. recognition.

When “DISABLE” is set in the data box, the standard

parameters are set in the “GAIN” and “LEVEL” data

boxes.

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

• The lower the level is, the brighter the whole view be-

comes.

Note: Teaching operations are performed through com-

ponent recognition.

Incorrect gain and level parameters lead to the ad-

verse result of teaching operations, causing some

trouble.

*6 [MANUAL NOZZLE CHANGE OPE] Key

When this key is pressed, the “MANUAL NOZZLE

CHANGE OPERATION” display (Fig. 4C85) appears on

the screen.

Designate the head and the nozzle and attach either “MF01”-

, “MF02”- or “MA06”-type nozzle.

Refer to “9. Manual Nozzle Change Operation of Section

4 in Volume 1” for details.

*7 RECOG. COMM.

When “DISABLE” is set in the “P.E.C.” and “COMPO-

NENT RECOGNITION” data boxes at the “TEST MODE”

display, the background color of “P.E.C. RECOG.” and

“COMP. RECOG.” becomes light red. (No background

color in normal cases)

In this case, the recognition processing is not made even if

the teaching operations are performed. Therefore, the re-

sults of various teaching operations are not reflected on the

offset data.

*8 ALL BEAM ZERO

When all beams are zeroed completely, the background

color turns green. Otherwise, the background has no color.
