 Center X

Refers to the coordinate in the X direction of the Black area based on the

part center. (Refers to the figure in the dialog box)

 Center Y

Refers to the coordinate in the Y direction of the Black area based on the

part center. (Refers to the figure in the dialog box)

 Size X

Size of the tetragonal area in the X direction (mm)

 Size Y

Size of the tetragonal area in the Y direction (mm)

 Brightness

Refers to the reference value of the White area. The White area with a

value greater than the reference value can be considered normal.

 Difference

Input the minimum difference in the brightness between <Area 1> and

<Area 2>. Generally, input 40.

 Shape

Select a shape according to the mark or concavo-convex on the bottom surface

of the LED. If the concavo-convex shape is selected, the brightness of the

selected area as well as the direction of a protrusion are checked. This,

therefore, prevents the part from being placed upside down.

 : There is no shape.

 : Triangle mark in the 0° direction.

 : Triangle mark in the 90° direction.

Part Registration

 : Triangle mark in the 180° direction.

 : Triangle mark in the 270° direction.

 : There is a recess or protrusion at the bottom surface of the part

in the left direction. (concavo-convex)

 : There is a recess or protrusion at the bottom surface of the part

in the right direction. (concavo-convex)

 : Selected when recognizing the shape of a part rotated by 90

degrees. This is not used currently.

 : When performing work by recognizing an FCOM (LED chip) in

4 directions

 Select the option function used when recognizing the LED using the vision

system in the <Data Setting> group.

 <Auto> check box

When there is a black area on the LED bottom surface (surface to be

recognized by the vision system) without specific marks such as a

tetragon or triangle on it, if this check box is selected, this image is

considered to be one of the images shown below.

 <4-Way Placing> check box

When recognizing an LED part, if it was picked up being turned 180°, this

function allows the part to be placed by turning it 180° without dumping

it. Mainly, this function is enabled when using a bowl feeder.

In order to use this function, the characteristics, position and size of the

LED mark must be inputted correctly. When there is a symmetrical mark

on the bottom surface of the part, exercise care not to use this function.

- : OK –Considered to be picked up normally.

- : NG –Considered to be picked up upside down.

 <Load default data> button

Shows examples for inputting an LED mark, and indicates the default

value saved in the system regardless of the part actually picked up.

This function is a guide for inputting certain types of value. Since this data

has nothing to do with the part to be actually placed, use the data for

reference only.

In addition, when it is desired to return all values inputted back to the

default value, this function can be used.

It is possible to judge whether inputted values for ‘Area 1’ and ‘Area 2’ are

appropriate by clicking the <Outline> button.

Whether to recognize the polarity must be checked by clicking the <Test>

button. If the recognition result is ‘OK’, when the <Test> button is clicked

again, with the part being turned 180° manually using the jog box, check

whether the recognition result is ‘NG’.

If the setup has been performed properly, click the <Close> button to save the

set value.

 <Rough Check> check box

When recognizing a part, if a recognition error occurs because the shape of the

part to be recognized does not match with the vision algorithm data, select this

check box.

If this check box is selected, even if a certain shape of the part to be recognized is

more or less incorrect when compared with the vision algorithm data, the part is

recognized correctly in case it is identical when checking the layout of the entire

parts.

As a part whose leads are slightly bent, it uses a crystal or aluminum capacitor.

This is applied only to Chip-rect, Chip-aluminum, etc.

 <Use Chip R flip auto check> check box

This is used only in the Part Edit Screen for Chip R part. It is selected to use the

function that checks the turnover of the Chip R part.
