3 Product description
Link arm
The link arm is the assembly located between the arm and the rotating column.
It consists of the link arm body with the buffers for axis 2. In combination with
the arm, there are three different lengths of link arm available to obtain the
specified reach.
Rotating column
The rotating column houses the motors of axes 1 and 2. The rotational motion
of axis 1 is performed by the rotating column. This is screwed to the base
frame via the gear unit of axis 1 and is driven by a motor in the rotating column.
The link arm is also mounted in the rotating column.
Base frame
The base frame is the base of the robot. It is screwed to the mounting base.
The flexible tube for the electrical installations is fastened to the base frame.
Also located on the base frame is the interface for the motor and data cable
and the energy supply system.
Counterbal-
ancing system
The counterbalancing system is installed between the rotating column and the
link arm and serves to minimize the moments generated about axis 2 when the
robot is in motion and at rest. A closed, hydropneumatic system is used. The
system consists of two accumulators, a hydraulic cylinder with associated hos-
es, a pressure gauge and a bursting disc as a safety element to protect against
overload. The accumulators are classified below category I, fluid group 2, of
the Pressure Equipment Directive. Different variants of the counterbalancing
system are used for floor and ceiling-mounted robots and for the F variants.
The mode of operation is reversed for ceiling-mounted robots, i.e. the piston
rod pushes against the link arm.
Electrical
installations
The electrical installations include all the motor and data cables for the motors
of axes 1 to 6. All connections are implemented as connectors in order to en-
able the motors to be exchanged quickly and reliably. The electrical installa-
tions also include the RDC box and the multi-function housing (MFH). The
RDC box is located in the rotating column. The MFH and the connector for the
data cables are mounted on the robot base frame. The connecting cables from
the robot controller are connected here by means of connectors. The electrical
installations also include a protective circuit .
Options
The robot can be fitted and operated with various options, such as energy sup-
ply systems for axes 1 to 3, energy supply systems for axes 3 to 6, or working
range limitation systems for A1. The options are described in separate docu-
mentation.
