GENERAL PRESENTATION
The arm consists of segments or members interconnected by joints
(figure 1.1).
Each joint comprises an axis around which two members pivot.
The movements of the robot’s joints are generated by brushless motors coupled to resolvers. Each of these
motors is equipped with a parking break.
This reliable and robust assembly associated with an innovative counting system allows the absolute
position of the robot to be known at all times.
The arm assembly is sufficiently flexible and is able to perform a great variety of applications.
Example: Handling of loads, assembly, process, application of adhesive beads, control/check and clean
room applications. This list is not restrictive: for further information, please consult us.
The various elements of the robot’s arm are: the base
(A)
, the shoulder
(B)
, the arm
(C)
, the elbow
(D)
, the
forearm
(E)
and the wrist
(F)
(figure 1.1).
The robot arm assembly thus contains the motorization, brakes, motion transmission mechanisms, cable
bundles, pneumatic and electric circuits for the user and the counterbalance system.
Of simple construction, the RX90B arm assembly consists of a rigid and encased structure (protection IP65
to standard NF EN 60529) to protect it against external aggressions. Its design is based on transmission
modules: JCS (STÄUBLI Combined Joint) used on joints 1, 2, 3 and 4
(figure 1.1).
The wrist consists of joints 5 and 6
(figure 1.1).
Arm balance is performed by an integrated spring system. The arm has a built-in spring counterbalance
system giving an attractive low weight system.
