(2) Teaching with an HMS

1) Device Select

These buttons switch a device used to perform teaching to another one.

2) Select HMS

These buttons specify an HMS to be used to perform teaching.

3) Teaching Point

Any of these buttons cannot be used with the HMS to perform teaching.

4) Light value setting

Any of these buttons cannot be used with the HMS to perform teaching.

5) Move Speed

Operate these buttons in the same manner as teaching with a camera.

6) Feed pitch

Set a value when you want to change the feed pitch of the electric feeder.

When you select an HMS device, the selected HMS lights up. When you press one of eight

arrow keys on the left side of the screen, the XY axes move, and the axes continue to move

while you are touching the button. The current coordinates X, Y and Z (values measured

with the HMS) to which the HMS has moved are displayed in the text boxes displayed on the

upper section of the screen.

CAUTION

To avoid a risk of injury, do not put your hands inside the machine

or move your face or head close the machine while the system is

teaching data.

When you use the HMS to teach the height of a component, a laser beam is

reflected due to the surface condition (such as a gloss and roughness) of the top

side (to be measured) of a component, and the system may not be able to measure

the height of the component.

In such a case, move the laser beam onto the tape carrier as shown in the figure

below, and use that point alternately to teach the Z-axis.

When you use the HMS to perform a teaching operation of a feeder RF04AS, a

tape, which is a surface to be measured, transmits the laser beam if the tape is

transparent or translucent. Therefore, the system cannot obtain any correct

measured value, and then the component pick-

up ratio may be made worse in

some cases. In such a case, move the laser beam to the tape travelling surface as

shown in the figure below, and then perform a teaching operation of the Z-axis at

this point. In addition, measure the thickness of the carrier tape (except the cover

tape), and then enter a value to the menu item for the picking stroke displayed on

the screen for the component pick-

up conditions invoked from the “Component”

data screen as described below.

(Example: when the tape thickness is 0.3 mm, 0.05 - 0.3 = - 0.25 mm)

Using this value as the default value, make fine adjustments of the picking stroke

when necessary.

(3) Teaching with a head device

The head device teaches the XY-axes, the Z-axis and the θ-axis respectively.

1) Device Select

These buttons switch a device to be used to perform teaching to another one.

2) Set Head

Specify a head nozzle to be used to perform teaching.

3) Move Axis Select

These buttons change the axis to be moved.

4) Light value setting

You cannot set this item by teaching with a head device.

5) Feed pitch

Set a value when you want to change the feed pitch of the electric feeder.
