2-2-2 Teach Entry

Teach entry allows for teaching coordinate data to the mounter.

Teach Entry using the Mouse

Teach entry in use of the mouse allows the driving axes to move according to the mouse

movement. When teaching, do not stick head, hands, or other parts of the body inside the

mounter. Serious injury can result. Also make sure non-operators are a safe distance from

the machine.

Before starting teach, make sure no foreign obstacles are left in the mounter or the tray feeder.

Otherwise, costly machine damage can occur.

Window:

1. Origin: Indicates the origin relative to which the obtained coordinates are

defined. The origin’s coordinates from the machine origin are shown

on the title bar.

3. Axis: Specify axis/axes whose coordinate to teach (XY axes/Z axis/T axis).

4. Head: Select a head to use for teaching.

For “XY axes”, select one from Head1 to Head4 (or Head1 to Head6), or

Main Teach Camera .

For “Z axis”, select one from Head1 to Head4 (or Head1-Head6).

5. Axis Speed/Head Travel:

Specify head movement speed (Smooth mode) or head inching

increment (Inching mode).

* Increment: 1% (maximum=100%)

6. Current Coordinates: Indicates the current teach coordinates. Displayed items vary

depending on the specified axis/axes.

Axis Coordinates

XY axes X and Y

Z axis Z

T axis T

7. <Rel/Abs>, <Reset>buttons:

First click [Rel] button, then [Reset] button to initialize current

coordinates as a customized origin to teach. Click [Abs] button to be

back to the original coordinates referenced from a programmed origin.

8. Navigator Matrix - Outer Arrow Buttons:

Press down an arrow button so the head moves to the direction of the

arrow with the axis speed specified at “Axis Speed”.

9. Navigator Matrix - Inner Arrow Buttons:

Press down an arrow button so the head moves to the direction of the

arrow. Head travels for the distance specified at “Head Travel” by a

click action, and the head movement gradually becomes fast as you

keep pressing an arrow button. To stop the head, release the mouse.

10. Teach Coordinates: After aligning the teach camera to the desired coordinates, click this

button to acquire the coordinates (one-point teach). Use this button also

to acquire coordinates after scanning a programmed step with

Trace>Move and adjusting the coordinates. When [Fiducial Correction]

option is selected, coordinates with fiducial offset appended are

acquired.

One

11. Fiducial Lamp: This lamp turns yellow when the fiducial compensation is applied to

the current coordinates.

12. <CLR> button: Clears all the acquired fiducial offsets.

13. [Trace] tab: Allows the specified head to trace the specified

(placement/pickup/fiducial) program steps. When the main/aux.

teach camera is specified, each traced step can be monitored on the

Vision Window. Click an X/Y/Z/T field of the program step and

right-click the mouse. The Teach dialog box opens. Then specify what

to trace.

14. Fiducial Correction: With this option selected, before the mounter traces the specified step,

the mounter scans fiducials to compensate the specified step.

Current Step

: Traces only the current step. Click <Move> button to execute. Z

coordinate can be traced also. Select an axis/axes under [Axis].

Step Type

: Traces specified type of steps from the current step to the end of the

program. Click <Step Type> button and select a type of steps from the

below choices:

<PCB>: Traces placement steps.

<Feeder>: Traces pickup points (only for ST-F/R).

<Fiducial>: Traces fiducial steps.

After specifying what to trace, click <Move> button at each step. Z

coordinate can be traced also. Select an axis/axes under [Axis].

15. <Move> button: Allows the specified head/camera to move to the coordinates on

specified program step under the conditions of [Trace] tab.

16. Fiducial Center Teach When < Fiducial Center Teach > in the teach window is clicked while

you are at a fiducial mark line, the center coordinates of the mark will

be detected. A message 「Do you want to teach coordinates?」 appears

when the center coordinates are detected, so click <Yes> if you want to

reflect the detected center coordinates to the program. If not, click

<No>.

17. Guide Window: When “XY axes” is specified for [Axis] and “Main Teach Camera” is

specified for [Head], pressing <Guide Window> button provides the

Chapter 2 Creating and Editing a Program

guide window outlining the component on the Vision Window. This

component outline is based on the component image data. The guide

window is available only when the component is processed with

single-view process and at the same time the component’s placement

angle T is either 0, 90, or 180.

18. Cross Hairs: Displays cross hairs on the Vision Window. The intersection of the

cross hairs corresponds to the teach point.

19. Search Line: See Chapter 9 Running a Job > Line Search (ASJ).

20. Fiducial Offset: Shows the current fiducial offset in performing <Fiducial Move>

operation (Y, Y, and T).

21. Fid No.: Shows [Fiducial] setting of the current program step (Placement &

Mark Data).

22. Set Illumi.: Enter the illumination setting for teach entry in the Illumination dialog

box (Teach>SetIllumi.). You can register up to seven illumination

settings for different purposes (teaching the PCB, feeder stations, tray,

and others). Enter the illumination setting as follows: Click a button

under [Group] and type in any name for identifying the setting. Drag

the sliders appropriately and click <Execute> button to activate the

setting. Check the Vision Window to see if the video image is clearly

monitored. If not, adjust the sliders and re-click <Execute> button.

When the adjustment is complete, under [Group], click the next button

and enter the setting the same way.

23. Wide View: Allows the teach camera to capture nine views and display the

assembled view as one picture in the monitor so that you can observe

wider area of a PCB.

Nine views are assembled from the standard center view and the eight

surrounding views which can be seen by the inner arrow buttons.

The wide view will be cancelled when you operate an axis, press the

<Move> button, or press the zoom buttons.

24. [2/4 Points] tab: When “XY axes” is specified for [Axis], specify the number of teach

points.

Four points (lines)

Two

The system calculates the center coordinates P. See the following Action

section for the procedure to use this feature.

Note: When performing the two-/four-point teach, do not use <Teach

Coordinates> button.

Action: The following shows how to teach X, Y coordinates on a PCB using the main teach camera

(two-point teach):

① In the program editor, click the X/Y field of the program step for which to perform teach.

② Click Tool>Teach or right-click in a cell you want to teach. The Teach dialog box appears.

③ Under [Axis], select “XY axes”.

④ Under [Head], select “Main Teach Camera”. The camera lighting is turned on.

⑤ Click [2/4 Points] tab. Select <Two>.

⑥ Click in the navigator matrix (Outer Arrow buttons) to assign head moving direction. The

head starts to move. While keep pressing the left button of the mouse, the head keeps

moving.

⑦ While watching both the actual head movement and the Vision Window, adjust head moving

direction by moving the mouse. Continue until the head comes close to the specified step.
