Painting system having a wall-mounted robot
View Patent ↗A painting system having a painting robot with a stationary base mounted to a wall of a paint booth in cantilever fashion. A stand is mounted to the stationary base and is rotatable around a first axis that is disposed substantially horizontal. A first arm is rotatably mounted to the stand around a second axis, and a second arm is rotatably mounted to the first arm around a third axis. The second arm is operable to rotate around the third axis 180 degrees relative to the first arm. An end effector is connected between the second arm and a painting tool. The end effector is operable to orient the painting tool.
1. A painting system for painting large objects, comprising:
a paint booth comprising a first wall; and
a painting robot comprising:
a stationary base mounted to the first wall and positioned so that a first axis of said painting robot is arranged at a non-perpendicular angle relative to said painting booth first wall;
a stand mounted to the stationary base, and rotatable around said non-perpendicular first axis;
a first arm rotatably mounted to the stand around a second axis; a second arm rotatably mounted to the first arm around a third axis, the second arm being operable to rotate around the third axis 180 degrees relative to the first arm and wherein the third axis is parallel to the second axis;
a painting tool; and
an end effector connected between the second arm and the painting tool, the end effector being operable to orient the painting tool.
2. The painting system according to claim 1 , wherein the end effector has three degrees of freedom of movement.
3. The painting system according to claim 1 , wherein the stationary base of the painting robot is mounted at a level above the object to be painted.
4. The painting system of claim 3 , wherein the stationary base of the painting robot is mounted on the first wall in a cantilever manner such that the first axis of the painting robot is spaced inwardly from the first wall.
5. The painting system of claim 1 , wherein the second arm is operable to rotate around the third axis 360 degrees relative to the first arm.
6. The painting system of claim 5 , wherein the first and second arms are each bent.
7. The painting system according to claim 1 , wherein the second axis is perpendicular to the first axis.
8. The painting system according to claim 1 , wherein an interior of the stationary base is accessible from outside the paint booth, through the first wall.
9. The painting system according to claim 1 , wherein the first axis extends in the direction of the length of the paint booth.
10. The painting system according to claim 1 , wherein the paint booth further comprises a second wall disposed opposite of the first wall, and wherein the painting system further comprises:
a second painting robot comprising:
a stationary base mounted to the second wall;
a stand mounted to the stationary base and rotatable around a substantially horizontal first axis;
a first arm rotatably mounted to the stand around a second axis;
a second arm rotatably mounted to the first arm around a third axis, the second arm being operable to rotate around the third axis 180 degrees relative to the first arm;
a painting tool; and
an end effector connected between the second arm and the painting tool, the end effector being operable to orient the painting tool.
11. A painting system for painting large objects, comprising:
a paint booth comprising a first wall and a floor; and
a painting robot comprising:
a stationary base mounted in a cantilever fashion to the first wall and positioned so that a first axis of said painting robot is arranged at a non-perpendicular angle relative to the painting booth floor;
a stand mounted to the stationary base and rotatable around said non-perpendicular first axis;
a first arm rotatably mounted to the stand around a second axis;
a second arm rotatably mounted to the first arm around a third axis, the second arm being operable to rotate around the third axis 180 degrees relative to the first arm and wherein the third axis is parallel to the second axis;
a painting tool; and
an end effector connected between the second arm and the painting tool, the end effector being operable to orient the painting tool.
12. The painting system of claim 11 , wherein the second arm is operable to rotate around the third axis 360 degrees relative to the first arm.
13. The painting system of claim 11 , wherein the stationary base is mounted to the first wall, above the object.
14. The painting system of claim 11 , wherein the painting robot comprises a plurality of connected cavities enclosing equipment arranged to move the painting robot, the cavities containing a non-ignitable gas.
15. The painting system according to claim 11 , wherein an interior of the stationary base is accessible from outside the paint booth, through the first wall.
