Operation Procedure

Basically, a component must be picked up when the nozzle is located at the

center of the component.

Therefore, “AUTOMATIC FEEDER AXIS ADJUSTMENT MODE” is

prepared to feed back and correct the positional deviation between the com-

ponent and nozzle center positions (the deviation calculated through compo-

nent recognition processing), using the statistical processing. However, there

may be some components which have a groove, a protrusion, etc., at their

centers, causing some hindrance to the component picks at the centers. To

cope with such components, the “PICK-UP LOCATION ADJUSTMENT”

function is prepared in the component library and can be selected to shift the

pick-up position intentionally from the component center.

The menus for pick-up location teaching are prepared to cope with each

case described before.

• Teaching Operation for Alignment of Component Center with Nozzle

Center

(1) Follow the teaching flow in Fig. 4C188 and perform the teaching opera-

tion on the component center position.

When no regulation is given to the shape of components and positioning

should be made simply to the component center, use the [TEACH PICK-

UP POS. [COMP. CENTER POS.]] key.

Note: The teaching operation must be performed while “ALL BEAM

ZERO” is displayed.

Teaching Procedure

Designate the objective feeder No. for teaching.

Select the [TEACH PICK-UP POS. [COMP. CENTER POS.]] key.

Select the [CENTER 1-PT.] key or perform the “DIAGONAL

2-PT” operation.

Press the [MOVE] button.

The placement head moves to the objective

feeder position for teaching and the image of

the pick-up location is captured by the P.E.C.

recognition camera.

When the [CENTER 1-PT.] key is selected,

the registration of the designated nozzle is made

together for graphic teaching to facilitate the

manual alignment operation with the trackball.

Positioning Operation with Trackball

Refer to “Trackball Operation” (described

later) for details.

• Teaching Operation for Setting of Eccentric Pick-Up against Hindrance

to Component Picks at Center

(1) Follow the teaching flow in Fig. 4C188 and perform the teaching opera-

tion on the component center position.

(2) Follow the teaching flow in Fig. 4C189 and perform the teaching opera-

tion on the pick-up location correction position.

When a component has a groove, a protrusion, etc., and cannot be picked

up at the center without any hindrance, use the [TEACH ECC. PICKUP

POS [PICKUP LOC. ADJ] key.

Before teaching the data for “PICKUP LOCATION ADJUSTMENT” in

the component library data to intentionally shift the pick-up location from

the component center, it is premised that the component center position

should be grasped first. Therefore, be sure to select the [TEACH PICK-

UP POS. [COMP. CENTER POS.]] key and perform the teaching op-

eration on the component center position. After that, select the [TEACH

ECC. PICKUP POS [PICKUP LOC. ADJ]] key to adjust the pick-up

location.

Note: When the center position is not grasped correctly and the teaching

operation is performed on the eccentric pick-up location, improper

values are fed back to “PICKUP LOCATION ADJUSTMENT

X, Y”, causing the component library data to lose its generality.

Teaching Procedure

Designate the objective feeder No. for teaching.

Select the [TEACH ECC. PICKUP POS [PICKUP LOC. ADJ] key.

Press the [MOVE] button.

An image is captured by the P.E.C. camera at

the pick-up location correction position of the

objective feeder for teaching.

The pick-up location adjustment data set up at

teaching execution is reflected.

Positioning Operation with Trackball

Refer to “Trackball Operation” (described

later) for details.

• Trackball Operation

[CENTER 1-PT.] Key

The cross hairs appear on the recognition monitor.

Adjust the cross hairs to the pick-up point, using the trackball.

(1) When the [CENTER 1-PT.] key is selected and the [MOVE] button is

pressed, the P.E.C. recognition camera moves to the designated feeder

No. position.

(2) Manipulate the trackball as shown in the following figure.

“DIAGONAL 2-PT.”

Specify the two edges of the component to be picked up or the embossed

mounting hole.

Specify the edge two points of the component in embossed.

Or, specify two corners (points) of the embossed mounting hole.

(1) When the [1POINT] key is selected and the [MOVE] button is pressed,

the P.E.C. recognition camera moves to the designated feeder No. posi-

tion.

“ (first point)” appears on the recognition monitor.

(2) Make an alignment with the trackball and press the right and left buttons

simultaneously.
