- the amplitude and the frequency of the deflection application to the coating medium beam S1 generated by means of the deflection device 20 can be changed as needed during an application and deflection process.
- more complicated deflection patterns corresponding to the pattern, the icon or the logo to be generated can be generated.
- the generated patterns, pictograms and company logos and / or detail / design applications are characterized in particular by their edge sharpness, which have a maximum deviation from a predetermined edge profile, which can no longer be perceived by the naked eye.
- the exit velocity of the coating agent is such that it does not rebound when hitting the component B and thus could lead to coating agent splashes.
- the deflection device 20 is designed for the pneumatic deflection of the coating agent beam Sl, z. B. by means of an air or gas stream.
- the application device 10 is designed for dispensing individual drops that produce a coating agent droplet jet Sl.
- FIG. 16 shows a schematic view of a deflection device 20, the z. B. in a coating device 1 shown in Figure 11 is applicable.
- FIG. 17 shows a schematic view of a deflection application curve for the deflection device 20 shown in FIG. 16, an applicator path for the associated application device 10 guided by the movement unit 30 and a resulting application.
- the application device 10 applies the coating agent beam S1 to the component B, while no deflection of the coating agent beam S1 occurs. As a result, a rectilinear strip application is generated.
- the application device 10 applies the coating agent beam S1 to the component B, while the
- Deflection device 20 is activated to deflect the coating agent beam Sl to the side outside by means of such an amplitude variation that a deflected part of the coating agent beam Sl with an undeflected part of the coating agent beam Sl on the component B to a unit. This will create a stripe application he testifies ⁇ which is wider than in the period tO to tl.
- the application device 10 applies the coating agent beam S1 to the component B, while no deflection of the coating agent beam S1 occurs. As a result, a rectilinear strip application as in the period t0 to t1 is generated.
- the application device 10 applies the coating agent beam Sl to the component B, while the deflection device 20 is activated to deflect the coating agent beam Sl laterally outward by means of such an amplitude variation that on the component B separated three from each other, parallel to each other extending
- Strip applications are generated.
- FIG. 18 shows a schematic view of a coating device 1 according to another embodiment of the invention.
- a continuous coating agent jet after leaving the application device 10 until reaching a decay length initially has a region which is connected in the beam direction. After the disintegration length, the coating agent jet disintegrates into droplets separated from each other in the jet direction. If the distance between the application device and the component is less than the disintegration length, the coherent coating agent beam reaches the component.
- the application device 10 shown in FIG. 18 is designed such that it outputs the coating agent in the form of a coherent coating agent jet S2 from the outlet opening 11, which still reaches the component B before reaching its decay length and thus in a coherent form incident.
- the coating agent jet can thus be a beam which is coherent at least in sections and / or at least in sections can be a droplet jet.
- the invention thus encompasses embodiments in which a coating droplet beam S1 comprising a single droplet impinges on the component B, and embodiments in which a coherent coating agent beam S2 impinges on the component B.
- the coating device 1, a handling unit, not shown, for. B. a multi-axis robot, for moving the component B relative to the application device 10 include.
- the application device 10, the deflector ⁇ device 20 and the management unit may be configured so that the component B during application and Ablenkvorgangs is moved at least temporarily by the handling unit along a predefined path relative to the application device 10 and alternatively or additionally, the component B is held static or stationary at least temporarily by the handling unit during an application and deflection process.
- the application device 10 and the handling unit can be configured such that the dispensing of the coating agent is temporarily interrupted while the handling unit moves the component B relative to the application apparatus 10, and subsequently the dispensing of the coating agent is resumed to another component position.
- the deflection device 20 can also comprise a deflection nozzle which is preferably integrated in the application device 10 and whose coating agent output direction can be adjusted relative to the application device 10 in order to be able to deflect the coating agent beam S1, S2.
- the invention thus also includes deflection devices 20 which are designed for the physical-mechanical action on the coating agent.
- the invention is not limited to the preferred embodiments described above. Rather, a variety of variants and modifications is possible, which also make use of the concept of the invention and therefore fall within the scope.
- the invention also claims protection for the subject matter and the features of the subclaims, independently of the features and claims referred to.
