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.

2. Various Functions

2.1 Equivalent Repetitive Pattern Function

Pattern program data for unit P.C.B.’s (same repetitive patterns) can

easily be created through a combination of coordinate data of repetitive

placement patterns and each placement pattern origin.

• The equivalent repetitive pattern function can be used when four pieces

of unit P.C.B.’s are arranged, forming constant patterns as shown

below and the same types of components are placed on each unit

P.C.B.
