Valve term inal

8.2.7.10 Valve terminal

The valve terminal consists of 12 valves (1), one for each segment.

The compressed air from the holding circuit (2) is distributed over 12 channels for the 12 segments. Each

of these channels has a valve. This enables the compressed air to be switched on or off for each

segment (3).

This means, after a component has been placed, the compressed air can be switched off for this

segment.

Before picking up a component, the compressed air is switched on again and vacuum is present at the

nozzle via the holding circuit with venturi nozzles. The disconnection of compressed air after placement

reduces the compressed air per placement head by approx. 40-50%.

The outer channels (4) are used to measure the holding circuit and supply the air blast or vacuum for the

pickup/placement circuit via the pressure control valve.

The SCS has two main tasks:

1. Controlling the DP drives

2. Evaluating the Z down light barrier.

The assembly consists of a carrier plate and two boards

(control module and power module).

The power and data supply is via the head CAN bus from

the intermediate distributor, E/D transformer to the SCS.

The SCS features 12 connectors, which establish the

connection for the power and data supply to the DP

drives.

E/D Transformer (for CPP Heads < Version 05)

8.2.7.11 E/D Transformer (for CPP Heads < Version 05)

▪ The energy and data transformer consists of a stationary and a rotating part.

▪ The three sliding contacts transmit the direct current voltage (24V/4A).

▪ Communication (the transmission of CAN Bus signals) is contactless. The transmitter is located on

the rear cover of the CPP head and the receiver module on the valve terminal.

▪ The connector (4) supplies power from the intermediate distributor.

▪ The centering pin fixes the stationary part in place via the rear cover of the CPP head.

▪ The rotating part is fixed with five screws to the valve terminal.

▪ The valve terminal consists of 12 holding circuit

valves, which can be switched independently at any

time and in any star position.

▪ Switching on the valves means “throughput”:

Compressed air is present at the venturi nozzles

(voltage = 0V). If a valve should fail or if it is without a

voltage supply, vacuum is always present at the

holding circuit.

▪ Switching off the valves means “valve closed”: There

is no compressed air present at the venturi nozzle

(24 V voltage is present). This saves compressed air!

Energy Transmission

▪ Two transmission leads are needed to transmit the energy supply: P24V (1) and GND (2).

▪ Another lead (3) (sliding contact) forms the connection between the rotating part and the housing

ground (ESD protection).

Contactless Energy Transformer (for CPP Heads from Version 05)

8.2.7.12 Contactless Energy Transformer (for CPP Heads from Version 05)

▪ The contactless energy transformer consists of two parts, a stator (1) and a rotor (2).

▪ Activating is done via an additional board that is located on the intermediate distributor 2 as a

piggyback board.

▪ The stator is fixed at the rear cover of the placement head, the rotating part, rotor, (2) is fixed to the

star frame via the terminal board.

▪ In the middle of the contactless energy transformer the transformer for contactless data transmission

is located.
