6.5 HEAD OFFSET Display

• This display allows teaching the head offset data.

The head offset data is used to correct the deviation between the component

recognition position and the placement position caused due to the deviation

of straightness (skew) of the up/down axis.

The offset values are calculated by recognizing the printed pattern on the jig

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

up by a nozzle with both component recognition and P.E.C. recognition cam-

eras.

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] key is pressed at the “TEACH OFFSET” display,

the following display appears on the screen.

Teaching Plate (Component Recognition Offset Jig: JG0085)

(Standard Accessory Part)

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

offset data for both heads on Beams A and B in the se-

quential order.

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

the machine starts the teaching operation.

The keys with a red frame can not be selected because the

head skip setting has been performed for such keys.

Note: Before performing the teaching operations, zero

both beams.

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

The machine performs the teaching operations of the head

offset data of both heads on Beam A or B.

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

and the [MOVE] button is pressed, the machine performs

the teaching operations.

The keys with a red frame can not be selected because the

head skip setting has been performed for such keys.

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

The machine performs the teaching operation of the head

offset data.

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 #.

The keys with a red frame can not be selected because the

head skip setting has been performed for such keys.

Note: Before performing the teaching operations, zero

both beams.

*4 Offset Data

Shown is the head offset data of each head on Beams A and

*5 TEACH CAMERA

A camera can be designated for teaching operations.

“AUTOMATIC”, “CAMERA-A1”, “CAMERA-A2”,

“CAMERA-B1”, or “CAMERA-B2” can be selected.

When “AUTOMATIC” is selected, a camera is automati-

cally selected for teaching operations.

When one of the above-described options except for “AU-

TOMATIC” is selected, the machine performs the teach-

ing operations with the designated camera.

*6 [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 refer-

ence 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.

*7 [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.

*8 [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.

*9 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).

Note: In this case, the recognition processing is not made

even if the teaching operations are performed.

Therefore, the results of various teaching opera-

tions are not reflected on the offset data.

*10 ALL BEAM ZERO

When all beams are zeroed completely, the background

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