7.13 SIEMENS interface

The conveyor interface on the placement machines from the HF series is configured to the

SMEMA standard. It is, however, still possible to use this interface in accordance with the SIE-

MENS standard. This is a significant benefit when an HF series machine is to be integrated into

older SIPLACE lines, in which case it would not be necessary to retrofit the older machines to con-

form to the SMEMA standard.

Simply configure the conveyor interface of the HF series machines to the SIEMENS standard and

connect the machines using the associated interface cable.

You can order this cable as an option with the retrofit instructions.

7.14 "Long board" option

The following PCB formats can be placed on the HF series of machines:

We can supply the "Long board" option as a retrofit kit for placing PCBs that are over 450 mm long.

If the "Long board" option is installed, then the following PCB formats can be processed:

The retrofit kit consists of the following parts:

– Complete mechanism: stopper, sensors, cables and assembly parts

– Optional CD for enabling the function on the SIPLACE Pro computer

– Retrofit instructions

7.15 Magnetic pin support

Wide PCBs tend to deflect during placement such that, under certain circumstances, the compo-

nents can no longer be placed with the desired accuracy. Highly curved PCBs also affect the

placement accuracy. This problem can be easily rectified by fitting magnetic pin supports on the

lifting table.

7.16 Vacuum pump

Every Collect&Place head has a separate vacuum generator that supplies the holding and place-

ment circuit with the vacuum that it needs. The vacuum generator works on the Venturi principle.

The HF/3 machine's compressed air consumption is approximately 550 Nl/min, which means that

the compressed air supply must be dimensioned accordingly. If the owner does not have sufficient

capacity locally, the associated investment costs would be high, so we supply a vacuum pump that

will provide the necessary vacuum.

Other advantages of using the vacuum pump are:

– It roughly halves the machine's compressed air consumption.

– It reduces the input pressure.

– The placement machine can be easily integrated into existing lines.

– The ongoing operating costs reduce according to the energy costs.

The vacuum pump is maintenance-free and 100% oil-free. They have sufficient capacity to supply

the holding circuits of the Collect&Place heads.
