Problems solved by technology

[0005] This transmission method increases the interval angle and reduces the positioning accuracy
[0006] Additionally, maintaining these systems is dangerous due to the risk of becoming trapped in the chain and transmission
[0007] Another, but not final, disadvantage is that these normally grease-lubricated transmissions generate a lot of fouling when in use

Embodiment Construction

[0022] With reference to said drawings, reference numeral 1 is used to designate the painting robot as a whole.

[0023] The painting robot 1 comprises a frame 2 which can be positioned on the floor of a work area. The frame can be equipped with legs 2A and feet 2B with height adjustment to position the height of the robot.

[0024] The frame can support a rotating workpiece holding carousel 50, which in the solution shown is equipped with three arms 51 characterized by bending.

[0025] In this specification, the term "curved" means that the length of the arm extends along a trajectory different from that of the straight segments connecting the operative ends of each individual arm.

[0026] An example of a "bent" arm can be created by connecting two or more rectilinear elements (e.g. box members) in positions at an angle to each other.

[0027] In another example, the "bend" arm is a unit shaped in a similar manner to a circular segment (as shown) or an elliptical segment....

Abstract

The invention relates to a spraying unit. The spraying unit includes a spraying robot having a frame supporting a base rotating around a first axis; and a workpiece holding rotary disc, wherein the base supports a first arm hinged around a second axis, the first arm supports a second arm hinged around a third axis, a wrist-shaped member which can move around at least a fourth axis, a fifth axis and an optionally sixth axis is restrained at an end portion of the second arm, the workpiece holding rotary disc includes at least two arms one end of which is provided with a workpiece holding table,and the workpiece holding table rotates around the axis (P) in a driven manner. The at least two arms are bent, and a movement transmitting line from the only engine-driven rotation assembly of the workpiece holding table to the workpiece holding table includes flexible shafts accommodated in the bent arms.

Description

technical field [0001] The invention relates to a painting unit formed by at least one robot and a workpiece holding carousel. In particular, the invention relates to painting units with robots having five or six axes. Background technique [0002] Useful painting robot accessories include a rotating turntable that feeds the parts to the painting station and rotates these parts to ensure that the painting is done in front of the robot (usually with five or six axes). The turntable arm according to known technology is configured so as to allow the operator to hold the test piece precisely in front of it while programming the first spray. [0003] One disadvantage encountered relates to the transfer of rotational motion from the main electric motor to the peripheral workpiece holding table. [0004] In the prior art, the motion is transmitted from the central body of the robot to the arm located on the arm by means of a belt / chain with the same profile as the arm of the turn...
