5.1 Introduction

5.1.1 Safety Instructions

This section provides a description of servicing work on the gantries of the SIPLACE 80S-20/F4.

5.1.3 General Comments

The SIPLACE 80S placement machine is equipped with a pair of x-gantry and y-gantry axes which are

mechanically independent of each other. The SIPLACE 80F placement machine as well as the adhesive

application machine possess one x- and one y-gantry axis.

The SIPLACE 80F/G gantries are of identical design. For this reason all of the servicing work which is

described in the following section will be presented on the basis of just one gantry.

The x and y axes are powered by direct current servo motors.

The position measurement system uses linear scales. For the x and y directions these are fixed directly to the

gantry axes. A read head scans the linear scales and in this way determines the position of the axis. This pro-

cedure is referred to as direct position measurement.

Power is transmitted from the direct current motors to the gantries via toothed belts and deflection.

5.1.4 Preparatory Work

We recommend that you always remove the components table before working on the gantry (see Section

12.1 “Removing and Installing the Component Change-over Table“). This will make your servicing work much

easier to perform.

5.1.4.1 Removing and Installing the Changeover Table

●

Disconnect the changeover table’s electrical and pneumatic connections.

●

Open the locking lever.

●

With a lift truck lift the components table over the taper pins and move the changeover table out of the

machine.

●

To re-install the changeover table proceed in the reverse sequence of operations.
