⑤ Gripper nozzle data

Grip position:

Enter a negative value (“-a”) into the “Y” field as the offset from the center of a component to

the side against which a component is pushed (“a”). Do not enter any value other than “0”

into the “X” field.

Horizontal Clearance:

Enter a negative value as the clearance between the side against which the arm on the

gripper nozzle fixed side is pushed and a component (“b”).

Usually, set the default value that is automatically input.

Nozzle direction at picking:

Specify the nozzle direction when the nozzle picks up a component that is supplied at 0

degrees. Specify one of the directions: 0, 90, 180 and 270 degrees.

Height adjustment:

Correction value (clearance between c and the top surface of the component) Normally, set

“- 0.5 mm” to keep a component horizontal.

③ Recog. Offset

The system moves the pick-up center position of a component (normally the center of a

component) to the center position of the VCS to center the component with the VCS.

However, since the system cannot pick up the center of a component such as an MCM

(Multi Chip Module) and the component position may be located outside the VCS field view

range, it may not be able to center the component with the VCS. In this case, enter offset

values (a, b) as shown below to ensure normal recognition.

④ Gripper nozzle data

Set this item as described in “1) Laser centering.”

⑤ S-VCS

Specify whether to recognize a component with an S-VCS or not.
