Definitions
- the invention relates to a joint device (e.g. a robot hand), in particular for carrying an application device and preferably for mounting on an application robot.
- a joint device e.g. a robot hand
- the application device and/or the application robot preferably serves to paint motor vehicle body components.
- Robot-guided atomizers for painting motor vehicle body components are usually mounted on an actuator referred to as a robot hand or robot hand axis, which usually comprises a plurality of joints coupled to one another, for precise path guidance.
- a robot hand robot hand axis
- An example of such a robot hand (robot hand axis) and such an atomizer is z. B. disclosed in EP 1 632 320 A1.
- atomizers have the disadvantage of a limited application efficiency, because usually only part of the applied paint is deposited on the components to be coated, while the rest of the applied paint has to be disposed of as so-called overspray.
- print heads as application devices, as are known, for example, from DE 10 2013002412 A1 and DE 102010019612 A1.
- print heads do not emit any spray mist of the paint to be applied, so that essentially no undesirable overspray is produced either.
- z. B. In addition to supplying the atomizer or print heads with z. B. electricity, paint, air, etc. is a wiring z. B. the electrical drive systems for the robot hand necessary. Also z. B. a supply of the drive systems, in particular their motors, with air for cooling purposes and / or flushing of robot housings with air may be necessary, z.

- the cable routing poses central requirements for the fulfillment of which two different philosophies in particular have prevailed on the market, namely internal cable routing and external cable routing.
- internal cable routing the media hoses and cables are guided centrally by a robot hand.
- This transfer requires, in particular, hollow shaft gears and motors arranged offset to the gear.
- the lines e.g. cables, hoses, etc.
- care must be taken to ensure that the lines are long enough. Care must also be taken to ensure that the leads do not come into contact with sharp edges or rough surfaces as this could damage them.
- the media hoses and cables are routed along the outside of the robot, in particular. This routing does not place any great demands on the design of the gearbox and the mounting of the motors.
- the lines e.g. cables, hoses, etc.
- the external line routing requires a relatively large amount of space and thus increases the interfering contour of the robot and/or the robot hand. Furthermore, external lines are unprotected and susceptible to contamination.
