2.4.5 Placement Head Section
Fig. 1A22
The machine is provided with a rotary turret that has several heads.
Each head is rotated by a direct-drive motor and several vacuum nozzles
can be attached to one head. The attached vacuum nozzles are used to
pick up components and place them on a P.C.B.
The turret has 12 placement heads.
Each head has 5 fitting holes for nozzles. Up to 5 types of vacuum
nozzles can be attached to each head.

2.4.6 Component Recognition Section
Fig. 1A24
The machine is provided with a mechanism that inspects (recognizes)
the components picked up by vacuum nozzles, using two component
recognition cameras and three light sources.
The following three operations are performed in the component
recognition system.
•
Component Detection
•
Component Inspection based on Component Library Data
•
Measurement of Positional and Angular Deviations

2.4.7 P.E.C. Recognition Section
Fig. 1A25
The P.E.C. recognition camera is used to detect the fiducial marks on a
P.C.B. and the amount of the positional deviation from the fiducial mark
coordinate data is calculated to automatically correct the position of a
placed component.
