The

Y axis

essentially consists of the following main modules:

– Y-axis linear motor (primary part) (1)

– Permanent magnet (secondary part of the Y-axis linear motor) (2)

– Linear distance measuring system (3)

– Guide system (4)

– Cable and hose carrier (5)

The Y axis is driven by a linear motor. The secondary part of the drive is made up of permanent

magnets and is mounted on the machine frame. The primary part is bolted to the gantry.

3.11 Vision cameras

A component camera is integrated into each Collect&Place head (see Fig. 3.7 - 5 on page 121,

Fig. 3.7 - 8

on page 129 and Fig. 3.7 - 11 on page 134). The stationary P&P component vision

camera (type 33) 55 x 45 digital for the TwinHead is permanently fixed to the machine frame.

WARNING

RISK OF HEAD CRASH 3

When the placement head is changed from the TwinHead to the Collect&Place head, the Twin-

Head's stationary component vision camera, P&P (type 33) 55 x 45, and stationary P&P compo-

nent vision camera (type 25) 16 x 16 digital must be removed, otherwise the Collect&Place head

will collide with the camera housings.

The

component vision module

is used to determine:

– the precise position of the components at the nozzle and

– the geometry of the package form.

The

PCB vision module

uses fiducials on the PCBs to determine:

– the position of the PCB,

– its rotation angle

– and the PCB skew.

The PCB cameras are fixed to the bottom of the gantries. They use fiducials on the

feeder mod-

ules

to determine the exact pick-up position of components, which is particularly important for

small components.
