Definitions
- the invention relates to a perforated plate for an application device for applying a coating agent, such as a paint, a sealant, a functional layer or an adhesive or a release agent. Furthermore, the invention relates to an application method in which such a perforated plate is used. In addition, the invention also encompasses a novel production method for such a perforated plate.
- a coating agent such as a paint, a sealant, a functional layer or an adhesive or a release agent.
- rotary atomizers are usually used, which atomize the paint to be applied by means of a rotating bell cup.
- these conventional rotary atomizers are well suited for full-surface component painting, the application of strips or other patterns and also the coating of partial surfaces is hereby problematic.
- drop generators for coating components, as described, for example, in DE 10 2010 019 612 A1.
- the coating agent to be applied is passed through a perforated plate having numerous through-holes, wherein from the individual through-holes of the perforated plate in each case emerges a coating agent beam which disintegrates into droplets which then impinge on the component surface to be coated and form a continuous coating agent film there.
- the problem with this known drop generator is the fact that the perforated plate has wetting surfaces at the hole openings which, during operation, are wetted in part by the exiting coating agent, which impedes detachment of the coating agent jet from the perforated plate.
- DE 691 23 224 T2 discloses a nozzle plate for an inkjet printer, although this known nozzle plate can not be used in the field of application technology.
- the invention includes the general technical teaching, the perforated plate on the upstream side and / or on the downstream side to provide a three-dimensional structuring, which reduces the annoying wetting tendency and / or reduces the pressure loss when flowing through the through hole.
- the invention initially comprises a perforated plate which is suitable for an application device for applying a coating agent, as described, for example, in DE 10 2010 019 612 A1.
- the invention is not limited to perforated plates for a particular type of application device, but also includes perforated plates that are suitable for other types of application devices.
- the perforated plate according to the invention is suitable for an application device which applies a paint, a sealant, an adhesive or a release agent to a component, for example to a motor vehicle body component.
- the invention is not limited to the above-mentioned examples of coating agents in terms of the type of the coating agent, but is also feasible with other types of coating agents. Under the category
- Functional layer fall layers that result in a surface functionalization, such as adhesion promoters, primers or layers to reduce the transmission.
- coating agent jet used in the context of the invention encompasses both continuous coating medium jets and droplet jets.
- the perforated plate according to the invention has, in accordance with the prior art, at least one through-hole which serves to pass the coating agent, wherein a coating agent jet preferably emerges from the through-hole emerges, which then impinges on the component surface to be coated and forms a coherent coating film there.
- the perforated plate according to the invention preferably has on at least one of its sides a three-dimensional structure which reduces the pressure loss of the fluid flowing through and / or reduces the wetting area on the downstream side of the perforated plate.
- the downstream side of the perforated plate at the border of the through-hole forms a wetting surface which is wetted during operation by the coating agent, which makes detachment of the coating medium more difficult.
- the through hole on the downstream side of the perforated plate be transitioned to a pipe stub protruding from the downstream side of the perforated plate so that only the end face this pipe stub forms a disturbing wetting surface.
- the disturbing wetting tendency can also be reduced by the fact that the peripheral edge of the hole opening on the downstream side of the perforated plate has a structuring which reduces the wetting tendency.
- Such structurings are known per se from the prior art under the keyword "lotus effect" and can consist for example of a microstructuring or a nanostructuring. Such structuring can also improve the flushability of the component.
- the pipe stub can be provided to further reduce the disturbing wetting surface, that the pipe stub has an outer circumferential surface which tapers towards the free end of the pipe stub, in particular conical.
- the wall thickness of the pipe stub thus decreases towards the free end of the pipe stub, so that the end face of the pipe stub at the mouth of the pipe stub is extremely small, resulting in a correspondingly small wetting surface.
- the wall thickness of the pipe stub at its free end may be smaller than ⁇ , 50 ⁇ , ⁇ or 5 ⁇ .
- the pipe stub has at its downstream free end an orifice, which is inclined relative to the longitudinal axis of the pipe stub.
- the pipe stub has a wall thickness which is smaller than the inner diameter of the through hole.
- the wall thickness of the pipe stub is in the range of 50% to 75% of the inside diameter of the through-hole.
- the pipe stub has a
- the through hole on the upstream side of the perforated plate has a Locheinmündung, which is aerodynamically optimized.
- this fluidic optimization in a nozzle Form the Locheinmündung exist.
- the Locheinmündung is only rounded to provide the lowest possible flow resistance.
- the hole opening of the through-hole on the downstream side of the perforated plate can be optimized in terms of flow, for example in the form of a nozzle or by rounding off to reduce the flow resistance.
- the through-hole preferably forms a Laval nozzle, but other nozzle types are possible.
- the through hole itself preferably has an inner cross section that is constant along the longitudinal axis of the through hole, wherein the inner cross section in the preferred embodiment of the invention is circular.
- the inner cross section may also be similar to a rectangle or an oval.
- the inner cross section of the through hole it is alternatively also possible for the inner cross section of the through hole to change along its longitudinal axis in order, for example, to form a nozzle shape.
- Such a change of the inner cross section of the through hole along its longitudinal axis is limited or possible with certain restrictions in conventional production methods (eg drilling, milling).
- the pipe stub protrudes only slightly from the downstream surface of the perforated plate, for example with a length in the range of 25% -100%, 50% -100%, 25% -50% or 25% -75% of Thickness of the perforated plate.
- Such a projection length of the pipe stub is sufficient to limit the wetting on the end face at the free end of the pipe stub.
- the pipe stub has a length between the upstream side of the perforated plate and the free end of the pipe stub, which is preferably greater than 10 .mu.m, 20 .mu.m, 50 .mu.m or 100 .mu.m and / or less than 1 mm, 500 .mu.m, 200 .mu.m or 100 ⁇ is.
- the orifice plate has a plurality of through holes, for example more than, 20, 50 or even more than 500 through holes.
- the area density of the through-holes, the distance between the immediately adjacent through-holes and the inner cross-section of the through-holes are in this case preferably dimensioned such that the coating agent beams emerging from the individual through-holes form a coherent coating agent film after impacting the component.
- the coating agent jets do not flow with other jets after they hit the component.
- the spacing of the through-holes from each other must be selected according to the coating agent properties and the required volumetric flow rate.
- the through holes of the perforated plate can optionally have the same inner cross section or different inner cross sections. The same applies to the diameter of the through hole at the outlet. The exit cross-section (diameter) determines the diameter of the coating agent jet (the drop) and is therefore much more important than the inside diameter.
- the individual through-holes are arranged at different distances from one another or are arranged in regions within which the distances between the through-holes are the same, but differ from region to region.
- the distance between the immediately adjacent through holes is at least equal to three times, four times or six times the inside diameter of the through holes.
- the through-holes can be arranged at the corners of a polyhedron, for example at the corners of a triangle, a trapezoid or a rectangle.
- the inner diameter of the individual through holes is preferably less than 0.2 mm, 100 m, 50 ⁇ or even less than 20 ⁇ , which is hardly achievable with cutting manufacturing process.
- the problem with the known drop generators is the production of the perforated plate, since, for example, machining processes (eg drilling) only allow relatively large through-holes with a diameter of at least 50 ⁇ m.
- the aspect ratio of the inner diameter of the through holes on the one hand and the thickness of the perforated plate on the other hand limited to an aspect ratio of 1:10, so that with a plate thickness of 0.5 mm, an inner diameter of only at least 50 ⁇ can be achieved.
- a disadvantage of the known perforated plates for application devices is therefore the problematic production, in particular of very small through-holes and very small three-dimensional structures.
- the invention preferably provides that the perforated plate is produced by etching, in particular by dry etching or wet etching.
- the through-holes can be produced by an etching attack on the perforated plate, the other regions of the perforated plate between the through-holes being protected by an etching stop and therefore not being removed.
- Etching technology production methods are known per se, for example from the field of semiconductor technology and therefore need not be described in more detail.
- the term used in the context of the invention for etching-producing the perforated plate thus means that at least the through-holes are etched-in while the perforated plate itself (i.e., initially without the through-holes) can be provided as a blank.
- An advantage of the etching-technical production of the perforated plate is the possibility of economical production of a perforated plate with a plurality of through-holes, since the manufacturing costs are independent of the number of through-holes.
- Another advantage of the etching-technical production of the perforated plate is that due to the production no burrs arise, so that can be dispensed with an elaborate post-processing to remove the burrs.
- etching production of the perforated plate enables exact parallelism of the through-holes, because all the through-holes are produced simultaneously with the same process and because, unlike drilling the through-holes, no drill can run. If, for example, in a first process step the etching-technical production is exposed completely vertically, all geometries are etched the same, since the etching attack can be controlled extremely uniformly, for example with gas.
- the orifice plate is at least partially made of a semiconductor material, such as silicon, silicon dioxide, silicon carbide, gallium, gallium arsenide or indium phosphide.
- a semiconductor material such as silicon, silicon dioxide, silicon carbide, gallium, gallium arsenide or indium phosphide.
- the invention is in terms of the semiconductor material not limited to the above examples of semiconductor materials.
- the perforated plate in the context of the invention may also consist of a different material, which allows an etching-technical production.
- iron metals eg steels, stainless steels and other alloys
- non-ferrous metals eg aluminum, molybdenum, tungsten, gold, silver, tin, zinc, titanium, copper and copper alloys
- semi-metals eg tellurium, boron
- Transition metals eg nickel and cobalt materials
- ceramics eg zirconium oxide, aluminum oxide
- the etching-technical production of the perforated plate offers the advantage that the through-bores can be aligned exactly parallel.
- the through holes with their longitudinal axes therefore have an extremely small angular deviation from one another or relative to the surface normal of the perforated plate, this angular deviation preferably being smaller than 1 °, 0.5 °, 0.01 ° or even smaller than 0.001 °.
- the invention is not limited to etch-technical production methods with regard to the production of the perforated plate, but can also be realized using conventional production methods. For example, machining methods (e.g., drilling, milling), punching or laser drilling may also be used.
- machining methods e.g., drilling, milling

- the coating may also be part of a sensor or a logic circuit.
- the perforated plate has a substantially constant thickness over its entire surface.
- the perforated plate has an outer edge with a greater thickness and a central region with the through-holes, wherein the thickness of the perforated plate in the region with the through-holes is less than at the edge.
- This reduction in the thickness in the area of the through-holes is advantageous because it reduces the flow resistance of the through-holes.
- the thickness of the perforated plate in the region of the through holes is therefore preferably less than 1 mm,
- the perforated plate for mechanical reinforcement has at least one reinforcing strip, wherein the perforated plate in the region of the through holes has a smaller thickness than in the region of the reinforcing strip.
- the perforated plate at the edge or on the reinforcing strip have a thickness of less than 2 mm, 1 mm or 0.7 mm.

- the invention also claims protection for an application method that uses an application device with such a perforated plate.
