Abstract

The present invention refers to a working assembly for a painting system, containing a mobile platform and a crank and slider-type oscillating mechanism, which reproduces movements transmitted to a shaft and that guides a paint gun, mimicking the process performed by painters. Thus, the mobile platform and the oscillating mechanism were designed to move unidirectionally over the surface, being able to move in two orthogonal directions and also to rotate in order to keep the platform level.

First claim

The invention claimed is:

1. A mobile platform and oscillating mechanism for coating flat surfaces, the platform comprising:
four movable pivots,
two adjustable arms,
a platform counterweight,
a suspension system of mecanum wheels and a compartment; and

the oscillating mechanism, comprising:
a flywheel,
an arm and a forearm with an arm counterweight and a forearm counterweight, respectively
a shaft,
a paint gun,
a pedestal, comprising:
an electric motor,
a flanged connection,
a lever,
an annular of an epicyclic gear train,
four gears and an epicyclic sun,

a first oscillating mechanism pivot located on the arm comprising two toothed pulleys, and connecting an inertia coupling belt with a forearm belt, and
a second oscillating mechanism pivot located on the forearm, comprising a toothed pulley that interconnects the shaft with the forearm belt.

2. The mobile platform and oscillating mechanism of claim 1 , wherein one of the two adjustable arms receives the platform counterweight that supports a purge sink and a purge reservoir.

3. The mobile platform and oscillating mechanism of claim 1 , wherein the pedestal is an integral part of the oscillating mechanism.

4. The mobile platform and oscillating mechanism of claim 1 , wherein one of the two adjustable arms receives a cable carrier.

5. The mobile platform and oscillating mechanism of claim 1 , wherein the forearm with the forearm counterweight contains the forearm belt.

6. The mobile platform and oscillating mechanism of claim 1 , wherein the arm with the arm counterweight is located on an axis of the pedestal.
