8-1 Before Teaching
8-1-1 Recognition
This machine has the function to recognize by the number registered to the recognition device as a
reference number. The shape data recognition and the block match recognition are available for
the recognition, depending on the shapes to be recognized.
1. Shape data recognition (board recognition)
When the object to be recognized has following shapes and each size is known, use this.
• Reference No.125 : Lamp value is automatically set.
• Reference No.126 : Lamp value is manually set.
∗ When the color contrast of the mark and the
background of it is not so clear as the paper
phenol board, it is used. (When the contrast is
not clear and the lamp cannot be automatically
decided, use this.)
2. Block match recognition (chip recognition)
For the recognition mark with a complex shape and an unclear outline, or when it is too large to be
in the recognition screen, use this.
• 4-point block
Reference Nos. 1 to 30 (chip recognition)
8-1-2 Lamp Value Adjustment Setting
To set the key rate, press the lamp value adjustment button. Each time the button is pressed, the
key rate is changed by +1 or -1. It is also possible to change the key rate by +10 or -10 each time
the button is pressed.
The teaching targets : PCB recognition, Bad Mark detect, Mount position and Vacuum
position learning.
a. Image inching
• Inching keys :
These inch an image by the inching rate
indicated on the button.
When the button indicates Direct, the center
moves to the point you pressed on the
image.
• Image inching rate button:
This changes the inching rate.
b. Lamp value adjustment
• Lamp value buttons:
These change the lamp value by the key
rate indicated on the button.
• Key rate button :
This changes the key rate.

8-2 Board Recognition Teaching
8-2-1 Board Recognition
This machine has the function to correct the deviation between the board and the print pattern
before mounting. This function obtains that position by recognizing the mark set on the print pattern
and is carried out by comparing it with original position.
8-2-2 Flowchart of Board Recognition Teaching
Board recognition teaching checks the mark positions and performs the recognition test.
If the mark position runs off extremely, look the coordinates data over again.

Board Recognition Teaching
8-2-3 Teaching Procedures
Before the board recognition teaching, ensure that the function switch “PCB Recognition” of the
created data is set ON on PT.
1. Display the main menu screen and
transmit the board data to change the
production board from PT.
2. Press
Data modify
.
• The data modification menu screen appears.
3. Press Production data teach .
• The production data teaching screen appears.
