5 Save the data.

Select <B2 SAVE DATA> or <B0 SAVE & QUIT> and press the [ENTER]

key. (To quit without saving, select <B3 RECOVER ADJUST> or <B7

QUIT> and press the [ENTER] key.)

Reference

The marker offset values adjusted here are stored in “Precision” - “MultiCam Marker” in

MCH_DATA mode. (See “6.1” in Chapter 3.)

6 Check the data.

Enter the Adjust Assistant mode in DATA Manager and run the VISION

TEST command for the marker using any component data (not necessary to

actually pick up acomponent with the nozzle) and check that the [Marker

2] XY data values displayed on the lower part the Adjust Assistant screen

are within ±0.005.

3.6 R-axis accuracy offset

This is the angular offset for the R-axis that rotates each nozzle shaft to

mount a component. When you select <3/2/A1 SELECT TARGET > - ”R

Axis Accuracy” and press the [ENTER] key, the current offset settings for

mounting angles of 0, 180, 90 and -90 degrees are displayed as shown

below.

When the multi-vision camera with the reference mounting angle specified

at 0 degrees is used, mountings at 90, 180 and -90 degrees might deviate

slightly. This deviation or offset can be corrected with the R Axis Accuracy

command in the MCH_ADJUST mode, in which the multi-vision camera

recognizes an SOP component at each mounting angle to obtain the offset

with respect to the recognition result at 0 degrees. Since the parameter at 0

degrees is used as a reference, it is always set to 0.00 degrees.

Machine adjust mode

To determine these offset settings, use the R Axis Accuracy command in

the Maintenance Manager. The machine automatically evaluates these

offset settings by recognizing the component that a head picks up while

rotating the nozzle shaft at the four angles of 0, 180, 90 and -90 degrees.

NOTE

If the reference mounting angle itself has deviated, the camera angle (R coordinate in the

CameraCoordinate parameters) must be corrected.

1 Prepare a component to be used as a reference.

Use a relatively large, popular component of known size which is

registered in the component database.

Reference

SOP components such as “No.704; SOP16-P1.27-6.4W” are recommended. If you are

going to use tape feeder components, install the tape feeder on the feeder plate in

advance.

2 Press the emergency stop button, then attach the nozzle

that matches the component.

You can skip this step for FNC heads.

3 Cancel emergency stop.

Check safety, then release the emergency stop button and press the

[READY] button.

4 Run the R Axis Accuracy command.

1. Select <3/3/B1 ADJUST TARGET> - "R Axis Accuracy" and press the

[ENTER] key.

2. Select the conveyor table, head No. and camera No. by pressing the

[ENTER] key.

The A-table multi-vision camera is designated “Cam. 5” and the B-table

multi-vision camera “Cam. 6”.
