Component Storage Box: Component Discharge

• When a recognition error occurs during the component recogni-

tion, the head moves to the component storage box and discharges

the error-caused component.

1.2.4 Component Placement

P.C.B. Positioning Section: Component Placement

• The heads move to the area over the placement coordinates on the

P.C.B. specified in the pattern program.

The deviation (X, Y) of the pick-up position (measured through the

component recognition) is also corrected at this time.

Fig. 2B16 Movement to Area over Placement Coordinates

• When a component is placed, the lowest limit of the required nozzle

is controlled according to the component library data.

• The vacuum valve closes, air blows out from the nozzle, and the

component is placed on the P.C.B.

1.3 Discharge of P.C.B.

(1) The components-placed P.C.B. is carried out to the R conveyor.

At the same time, a new P.C.B. is carried to the P.C.B. positioning

section from the L conveyor.

(2) The components-placed P.C.B. on the R conveyor is transferred to

the output machine by the R conveyor.
