C&P12 Placement Head - Special Features

When retrofitting the vacuum pump option, the Venturi vacuum generator for the C&P6/12 head is re-

placed with the retrofit kit vacuum pump C+P6/12 [00119796-xx].

The holding circuit is therefore operated permanently via the vacuum pump.

The placement circuit continues to generate its vacuum with compressed air according to the Venturi

principle.

When the placement head is in waiting position, the star is between two star positions (half-cycle). In this

intermediate position, the holding and pickup cycles are interconnected via the cross-section, leading to

an increased vacuum consumption.

The "vacuum consumption" of the placement machine depends only on the number of placement heads

and the size of the nozzles.

The more C&P12 heads are connected to the vacuum pump, the lower the vacuum level will be at the

nozzles.

When the placement operation begins, the vacuum increases with each component picked up. An aver-

age vacuum value will soon form, based on the number of nozzles closed at the same time (with picked

up components) and number of nozzles open (components placed).

Installation Location

The vacuum pump is installed at location 1 and the connection unit in location 2.

3.2 Pneumatic and Vacuum Supply

Pneumatic and Vacuum Supply

The following diagram shows the conversion of a machine with two C&P20 A/P heads to vacuum pump

operation.

A maximum of two C&P20 A/P heads can be connected to one vacuum pump.

Preconditions (according to machine configuration) see "2.8 C&P20A/P Placement Head - Special Fea-

tures" [ ➙ 85].

The machine monitors when the vacuum pump is switched on and off e.g. after longer production stand-

still times.

CAUTION

Safety instructions and manufacturer's instructions

In addition to the safety instructions in the introductory chapter, the manufacturer's safety in-

structions, installation and setup instructions apply to the vacuum pump and must be observed.

Avoid switching the placement machine and vacuum pump on and off multiple times within a

short period. This can have a negative influence on the service life of the pump.

The placement machine monitors when the vacuum pump is switched on and off e.g. after long-

er production standstill times.

CAUTION

Switching the compressed air off

Never turn the compressed air on during the conversion, as this could lead to placement head

damage, depending on the installation status.

CAUTION

Gantry with TwinHead or CPP

When using a TwinHead or CPP placement head, never convert the pneumatic supply, gantry

distributor or trailing cable! If you do, there is no guaranty that the TwinHead or CPP will function

properly.

Consequences

CAUTION

Switching the machine on and off

Avoid switching the machine and vacuum pump on and off multiple times within a short period.

This can have a negative influence on the service life of the pump.
