3. RECOGNITION ERROR IMAGE SAVE SET-UP Display

When the [RECOG ERR IMAGE SAVE SET-UP] key is pressed at the “AUTO

OPERATION SET-UP” display, the following display appears on the screen.

Set a parameter for each label (MODE, CMPNT RECOG SEL, IMAGE NO)

to analyze the cause of a recognition error in comparison with the error image

on the monitor.

When “SAVE” is set in the “FUNCTION” data box, the image which matches

the save mode (parameters set for “MODE” and “CMPNT RECOG SEL” dur-

ing operation) is stored in memory.

• Error images stored in memory can be saved on a floppy disk and sent to us

for error analysis.

Refer to “4.1 Error Image Save Function of Section 3 in Volume 4” for

details.

FUNCTION : “SAVE” or “DON’T SAVE”

MODE : “ALL”, “CMPNT RECOG”, “P.E.C. RECOG”

CMPNT RECOG SEL:

“OFF”, “CAMERA NO”, “COMPONENT ID”, “FEEDER NO”,

“HEAD NO”, or “NOZZLE NO”

CAMERA NO : The camera No. must be specified.

COMPONENT ID : The component ID must be specified.

FEEDER NO : The feeder No. must be specified.

HEAD NO : The head No. must be specified.

NOZZLE NO : The nozzle ID must be specified.

Note: As for “CMPNT RECOG SEL”, the set parameter is valid only

for those related to component recognition errors.

Setting of “RECOGNITION ERROR IMAGE SAVE” for “P.E.C.

RECOG.2 is unconditional.

3. RECOGNITION ERROR IMAGE SAVE SET-UP Display

IMAGE NO: [16] (25% Resolution)

[ 4] (50% Resolution)

[ 1] (100% Resolution)

Notes: (a) The image data stored in memory is cleared when the parameter in

the “IMAGE NO” data box is changed, the recalled recognition

error data is deleted, or the power switch of the machine is turned

off.

(b) When “16” or “4” is set in the “IMAGE NO” data box in the case

of the divided recognition, only the error-caused image data is

stored in memory.

(For example, when an error is caused in the component during

the fifth recognition operation (out of nine recognition operations),

only the data of the image captured during the fifth recognition

operation is stored in memory at a resolution of 25% or 50%.)

When “1” is set in the “IMAGE NO” data box, up to three images

are stored in memory at a resolution of 100%.

(For example, when an error is caused in the component during

the fifth recognition operation (out of nine recognition operations),

the data of the images captured during the third, fourth, and fifth

recognition operations is stored in memory at a resolution of

100%.)

analysis (investigation and analysis on maker side) of recognition

errors. That is, “1” must be set in the “IMAGE NO” data box at

the “RECOGNITION ERROR IMAGE SAVE SET-UP” display.

4. AUTOMATIC TUNING Display

When the [AUTOMATIC TUNING] key is pressed at the “AUTO OPERA-

TION SET-UP” display, the following display appears on the screen.

The following parameters are used to periodically adjust minute deviation

(caused due to the thermal expansion of the ball screw) in the position of each

section during automatic operation.

COMP. CAMERA POSITION

MODE: “ON” or “OFF”

“ON” or “OFF” can be selected to determine whether or not the compo-

nent recognition camera position should be corrected periodically ac-

cording to the number of components to be placed.

In normal cases, it is recommended that “ON” should be set in the data

box.

Note: When no checker marks are used, set “OFF” in the data box.

COMPONENTS

[0] : No automatic correction operation is performed for each

number of components to be placed.

[1 to 250] : Correction is made according to the specified number of

components to be placed. (Beam-Based Management)

When “ON” is set in the “MODE” data box, the correc-

tive actions take place automatically before component

recognition operation after the P.C.B. is transferred to the

P.C.B. positioning section.

When the number of components (components to be placed

on a production P.C.B.) per beam is smaller than the set

number of components, the corrective actions do not take

place in the middle of placement operation.

Because the internal counter for interval monitoring is

cleared through the above-described corrective actions (the

actions which take place during P.C.B. positioning), no

corrective actions take place in compliance with the num-

ber of components to be placed on several P.C.B.’s.
