A maximum of twelve components can be picked up from the feeders (X feeders). This value also

depends on the component spectrum.

The component sensor checks the pickup/place positions, to see whether a component has been taken

by the nozzle or placed on a board. On the way to the placement position, the components are rotated

into the correct placement position and optically centered. This is performed with the digital component

camera on the head or, for medium/sized and large components, via a stationary camera. Before

placement is performed, the angle and X/Y position correction, determined by the Vision system, is

applied. The X/Y position correction is calculated into the placement position, while the angle correction

is applied separately to each segment. This is possible as each segment can be rotated independently

of the star position. The components are then carefully and accurately placed down on the board, with

an air blast.

Features:

▪ Each segment has its own DP drive for rotating of the components into the correct position. The

segments are therefore no longer rotated into the correct angle in one single star position but can

now be rotated separately from one another.

▪ Each segment has its own vacuum generator.

▪ The so/called valve terminal is used to switch the supply pressure on and off for each segment. This

reduces the compressed air consumption by up to 40-50%.

▪ In addition, each DP drive has a light barrier Z down. There is no moving cable during the upwards

and downwards movement of the Z axis.

▪ The Z drive for the segments is realized via a linear motor with linear position measuring system.

The secondary part is now integrated into the Y axis, meaning that there is no moving cable during

the upwards and downwards movement of the Z axis.

Nozzle Changer (NC)

Nozzle changer for X machine

Legend

▪ In X series machines, a maximum of twelve nozzle changers are possible for each location,

depending on the machine configuration.

▪ The nozzle changer for the X machines has been extended to include the following functions:

– Magazine ID

(1) Nozzle changer carrier (2) Microswitch 1, 2 and 3 for magazine query

(3) Actuator for opening and closing the NC

magazine

(4) Unlocking lever for NC magazine

(5) Fixture clips for NC magazines

– Height query

▪ The nozzle changer carrier can accommodate the various magazine types for the C&P20A and CPP

heads.

▪ The machine recognizes the configured magazines via the magazine query (microswitch).

If the wrong magazines are configured for the head, a warning will be issued to prevent a head crash.

– 10xx magazine: Switch 2 (center) pressed

– 20xx magazine: Switches 1 and 3 pressed

– 28xx magazine: Switches 1, 2 and 3 pressed
