P.C.B. Positioning Section:

P.E.C. Recognition (Recognition of Placement Position)

• The P.E.C. camera is used to detect through P.E.C. recognition if

the placed components are shifted from the correct position or not.

Note: This will be performed only when specified in the pattern

program.

Nozzle Stocker: Nozzle Change

• A vacuum nozzle is selected for components and the attached

nozzle is replaced with the proper one.

The vacuum nozzle on the placement head is stored in the nozzle

stocker and the required one is taken out of the stocker.

1.2.2 Component Supply and Pick-Up

Each Feeder: Component Supply

• Each feeder (the tape, the vibratory stick, or the multi-layer tray

feeder) specified in the pattern program sends out the components

to the supply position, using the tape feed mechanism.

Feeder Base: Component Pick-Up

• The heads move to the supply position of each feeder and the

vacuum nozzles pick up the components.

Movable and Fixed Cameras:

Image Capture for Component Recognition and Component

Recognition

• The movable or the fixed camera captures an image of the compo-

nent for recognition.

The component recognition camera is automatically selected ac-

cording to the component library data.

• The machine is provided with two component recognition systems

- "Back Lighting Recognition System" and "Front Lighting Recogni-

tion System". The lighting method specified in the component li-

brary is automatically selected.

The following component recognition takes place.

(1) Component Detection

All components can be detected.

(2) Component Inspection

Each inspection is made according to the component library.

(3) Measurement of Positional Deviation (X, Y) and Angular

Deviation (θ) between Component Recognition Camera
