Description:

The invention is based on the object of providing an optically improved symbol and/or character formation by coating removal using a laser. This object is achieved by a method for producing and/or processing a plastic component having the features of claim 1 and by a component arrangement having a plastic part according to the features of claim 7. Preferred or advantageous embodiments of the invention result from the dependent claims, the following description and/or the attached figures.

A method for producing and/or processing a plastic component is proposed. The plastic component is preferably designed for a vehicle exterior, in particular for arrangement on the vehicle exterior.

A plastic base component is provided as part of the method. It is possible for the plastic component to be primary formed from a plastic raw material and optionally additionally formed as part of the process. The basic plastic component is preferably initially uncoated, with it being coated and further processed as part of the method in order to produce the plastic component as the end product.

For example, the plastic base component is translucent and/or has translucent properties. In particular, the plastic base component can be formed from a polycarbonate light scattering material as the plastic starting raw material.

A first base layer with a first layer thickness is applied to the plastic base component. The first base layer is preferably in the form of a first base lacquer layer. The first base layer is preferably colored. It is particularly preferred that the first base layer is translucent and/or has light-transmitting properties.

A second cover layer with a second layer thickness, in particular a second original layer thickness, is applied to the first base layer. The second top layer is preferably in the form of a second top coat layer. The second cover layer is preferably applied to the first base layer at least over part of the area, preferably over the entire area. The application takes place in particular after drying and curing of the first base layer.

The second cover layer is preferably designed to be opaque. The second cover layer is preferably of a different color than the first lacquer layer. In particular, the first lacquer layer and the second lacquer layer have different colors and/or colorings. The second cover layer preferably forms a visible side of the plastic component.

According to the invention, the second cover layer is partially removed in at least one functional area. Alternatively or additionally, the second layer thickness is reduced in the at least one functional area. A partial removal of the second cover layer and/or a reduction in the second layer thickness preferably takes place after curing of the second cover layer in the at least one functional area. The at least one functional area forms in particular at least a partial area of the second cover layer and/or the visible side.

In a preferred embodiment of the invention, the second cover layer is partially removed and/or the second layer thickness is reduced in the at least one functional area by laser processing, in particular by laser removal. For example, a laser, such as a pulsed fiber laser, with a wattage between 60 and 120 watts, in particular with a Wavelengths of 1055 to 1070 nanometers and/or with a focusing lens of 180 to 254 millimeters are used in the process. The partial removal of the second cover layer and/or the reduction of the layer thickness in the at least one functional area is carried out in particular in a nominal power range of 5 to 20 watts. A beam path width is preferably at least 1 micrometer and/or at most 5 micrometers.

The multicolored selective coating of plastic basic components often poses a challenge, especially in the automotive sector, since there is usually a triangle of tension between optical quality, process duration, the associated costs and durability requirements. Furthermore, there is often a demand for the highest possible degree of process individualization. A highly individualized production process without time-consuming machine conversions can be guaranteed in particular by processing the paintwork using the laser.

In a further preferred embodiment of the invention, the second cover layer is completely removed in at least one removal area, in particular down to the first base layer arranged underneath. The first base layer preferably remains in its first layer thickness or essentially remains in its first layer thickness. It is possible that the laser, when removing the second cover layer, attacks and/or stresses the underlying first base layer to a small extent. In particular, the goal is to keep this attack as low as possible.

The complete ablation of the second cover layer in the ablation area is preferably carried out by the laser as part of the laser ablation. It is carried out in particular in a nominal power range from 20 to 45 watts. For this it is advantageous that the second cover layer is thinner than the first base layer, preferably as thin as possible, so that the complete removal can take place productively. The first base layer is preferably visible in a plan view of the visible side in the area that has been removed. It is particularly preferred within the scope of the invention that the ablation area is adjacent to the functional area. In particular, the functional area surrounds the ablation area at least in sections, preferably completely. Alternatively or optionally in addition, the ablation area surrounds the functional area at least in sections, preferably completely.

In a preferred method step, it is provided that a shadow is cast for the ablation area by means of the functional area and/or a three-dimensional effect (3D effect) of the ablation area is generated. In particular, the ablation area is optically widened at least in sections, preferably completely, by the functional area. In particular, an optical depth and/or three-dimensionality of the ablation area is particularly emphasized and/or emphasized.

The functional area is preferably roughened and/or matted, in particular during and/or as a result of the laser processing. The formation of shadows and/or the 3D effect can be implemented particularly well through the matting. It is advantageous that particularly decorative selective coatings with 3D effects and/or shadows can be realized through the production of the functional area and the ablation area.

In a possible constructive process step, the plastic component is backlit. In particular, the plastic component is backlit on a rear side of the plastic component, which is opposite the visible side. For example, a lighting device for generating light is assigned to the plastic component for its backlighting. The lighting device can, for example, comprise at least one light-emitting diode as a light source and optionally additionally or alternatively at least one light guide. Other suitable light sources are also possible within the scope of the invention.

Preferably, the light passes through the first base layer where the ablation area is located. In particular, the light generates a luminous area in the ablation area. This can be ensured in particular by the first base layer being translucent and/or translucent.

It is particularly preferred within the scope of the method that the functional area is not illuminated and/or is not transilluminated. This can preferably be ensured in that the second cover layer is designed to be opaque. In particular, the light cannot shine through the reduced second layer thickness in the functional area. It can thus be ensured in an advantageous manner that during the backlighting of the plastic component only the removal area is illuminated on the visible side. In particular, in a plan view of the visible side, only the removal area of the plastic component can be perceived as the illuminated area. It is advantageous that the plastic component through the possibility of backlighting and in particular is visually particularly appealing due to the formation of the luminous area.

In a further preferred process step, only the first base layer and the second cover layer are applied to the plastic base component as a coating. In particular, no further layer, for example no clear lacquer, no finish, etc., is applied to the second cover layer and/or in the functional area and/or in the removal area. The further layer is dispensed with in particular against the background that the functional area is matted and this would be changed or eliminated by the further layer. In particular, the shadowing effect of the functional area would be prevented by the application of the further, in particular transparent, layer of lacquer. Optionally, the 3D effect of the functional area could be impaired by the application of the additional layer.

Another object of the invention is a component arrangement with a plastic component. The plastic component is formed from a plastic base component, which is primary formed and/or reshaped from a plastic starting raw material, the plastic base component being coated with a first base layer and a second cover layer.

The first base layer has a first layer thickness, being embodied, for example, as a first base lacquer layer. In particular, the first base layer is applied directly to a surface of the plastic base component, at least in regions. The first base layer preferably has a first color or first coloring. In particular, the first base layer is translucent and/or translucent. The first layer thickness is optionally at least 18 micrometers, preferably at least 20 micrometers, in particular at least 30 micrometers and/or at most 35 micrometers.

The second cover layer has a second layer thickness, in particular a second original layer thickness, being embodied, for example, as a second top coat layer. In particular, the second cover layer is applied to the first base layer at least in regions, preferably over the entire surface. The second cover layer preferably has a second color or second coloring, which is different from the first color and/or first coloring. In particular, the second cover layer is impermeable to light and/or opaque. The second original layer thickness is optionally at least 5 micrometers and/or at most 20 micrometers, preferably at most 15 micrometers, in particular at most 10 micrometers.

Provision is made for the second cover layer to have at least one functional area in which the second, in particular the second original, layer thickness is reduced. In particular, the second cover layer is not completely removed and/or removed in the functional area. A reduced second layer thickness in the functional area is, for example, at least 2 microns and/or a maximum of 10 microns, in particular a maximum of 6 microns, in particular a maximum of 3 microns. The plastic component is preferably produced and/or processed within the scope of the method according to one of Claims 1 to 6 and/or according to the previous description.

In a preferred embodiment of the invention, the second cover layer is matted in the functional area. Matting in the functional area is produced in particular by the partial laser ablation of the second cover layer.

In a further preferred embodiment of the invention, the plastic component has at least one area that has been removed. The two top layers are preferably completely removed in the removal area. As a result, the first base layer is visibly arranged in the removal area, in particular in a plan view of the visible side of the plastic component.

A possible constructive configuration of the invention provides that the ablation area is arranged adjacent to the functional area. It is particularly preferred within the scope of the invention that the functional area forms a shadow of the ablation area. Alternatively or optionally in addition, the functional area creates a 3D effect for the removal area.

In a further possible constructive implementation of the invention, the ablation area is designed as a sign. In particular, the area removed represents the sign in the plan view of the visible side of the plastic component. For example, the sign can be a symbol, a graphic, a letter or a number. In principle, it is possible within the scope of the invention for the plastic component to have a plurality of ablation areas and/or a plurality of functional areas, in which case one, several or all ablation areas and/or functional areas can match in terms of their shape, their progression, their shape, etc., or can be designed differently .

It is particularly preferred within the scope of the invention that the functional area partially or completely surrounds the character or that the sign partially or completely surrounds the functional area. The functional area is preferably arranged adjacent to one, two, three or even all sides of the sign when viewed from above on the visible side. For example, the functional area is arranged to the right and/or left of the character in the top view of the visible side and optionally additionally above and/or below the character and/or between components of the character. In particular, the functional area forms the shadow cast by the character through suitable positioning relative to the character. In particular, the functional area creates the 3D effect for the character by the appropriate positioning relative to the character.

For example, the functional area is designed to be uninterrupted and/or continuous. In particular, the functional area surrounds the respective sides and/or components of the sign without interruption. Optionally, the functional area continuously borders on several sides of the sign, e.g. at least one of the sides is horizontal and the other side is vertical or inclined or curved. This can be the case, for example, if the character is one of the numbers 2, 4, 7 or one of the letters K, L, T.

It is also possible within the scope of the invention that the functional area is partially surrounded by sides of the character, e.g. if the character is one of the letters E, F, H, M, N, U, V, Y or one of the numbers 3, 5. Alternatively, the functional area can be completely enclosed by the character, e.g. if the character is the number zero or one of the letters O or Q. Optionally, the functional area can extend without interruption and/or continuously between several consecutive characters. Several consecutive characters can also be at least partially surrounded by the functional area.

It is also possible within the scope of the invention for the character or components of the character to border on several unconnected and/or independent functional areas. For example, the functional areas are arranged one after the other or next to one another, in particular at a distance from one another. Several or all functional areas can be oriented in the same direction or differently.

Preferably, the character borders on one, some or all functional areas at least in sections or the character surrounds one, some or all functional areas at least in sections. A combination of two or more functional areas of which at least one is surrounded by parts of the sign and of which at least one other functional area is adjacent to another part of the sign can be used, for example, with the letters A, B, P, R or with the numbers 4, 6, 9 as signs to be the case.

A possible constructive realization of the invention provides that the component arrangement comprises an illumination device which is designed to generate and/or emit light. The lighting device is preferably assigned to the plastic component for its backlighting. For example, the lighting device can be attached to the plastic component or connected to it. However, it can also be arranged on the vehicle exterior or on neighboring or adjoining parts of the plastic component if this is attached to the vehicle exterior.

Within the scope of the invention, it is preferred that a lighting area is formed in the ablation area when the lighting device emits the light. In a plan view of the coated visible side, the luminous area is preferably formed exclusively in the ablation area in which the second cover layer has been completely removed. The exclusive transillumination of the ablation area is ensured in particular by the fact that the second cover layer is impermeable to light and/or opaque, whereas the plastic base component and the first base layer are designed to be transparent and/or translucent.

In a preferred constructional embodiment of the invention, the plastic component is designed to be arranged on the outside of a vehicle, e.g. a car or truck. For example, the plastic component is a decorative strip or a section of a radiator grille of the vehicle. In particular, the plastic component can be a radiator protection frame or a radiator protection grille of the vehicle.

Corresponding or identical parts are each provided with the same reference symbols in the figures.

the 1 shows a cross section through a plastic component 1. The plastic component 1 consists of a plastic base component 2, a first base layer 3 and a second cover layer 4. The plastic base component 2 is formed from a translucent and/or transparent plastic raw material, e.g. from a polycarbonate scattering light material. The first base layer and the second top layer are designed as differently colored lacquer layers.

The first base layer 3 is applied directly to the plastic base component 2 over the entire surface. It is designed to be impermeable to light and/or opaque. The first base layer 3 has a first layer thickness D1 of at least 18 micrometers, preferably at least 20 micrometers, in particular at least 30 micrometers and/or at most 35 micrometers.

The second cover layer 4 is applied directly to the first base layer 3 . It forms the visible side of the plastic component 1. The second cover layer 4 is impermeable to light and/or opaque. It has a second layer thickness D2, which is thinner than the first layer thickness D1. The second layer thickness D2 is at least 5 micrometers and/or at most 20 micrometers, preferably at most 15 micrometers and in particular at most 10 micrometers.

An ablation area 5 is introduced into the second cover layer 4 by laser processing, in particular by laser ablation. The second cover layer 4 has been completely removed and/or removed in the removal area 5 so that the first base layer 3 is visible in the removal area 5 in a plan view of the visible side.

As part of a method for producing and processing the plastic component 1, the plastic base component 2 is provided, this being e.g. formed and/or reshaped from the plastic starting raw material. First the first base layer 3 is applied to the plastic base component 2 . After the first base layer 3 has dried and cured, the second cover layer 4 is applied to the first base layer 3, and is then dried and/or cured.

The plastic component 1 is processed in particular such that the ablation region 5 is introduced into the second cover layer 4, in particular by means of a laser. The complete ablation to form the ablation area 5 in the second cover layer 4 is carried out, for example, in a nominal power range of 20 to 30 watts.

the 2 shows the plastic component 1, the plastic component 1 in particular compared to the 1 is further processed. A functional area 6 adjoining the ablation area 5 is introduced into the second cover layer 4 by means of laser processing and/or laser ablation. In the functional area 6, the second cover layer 4 has a reduced layer thickness D3 of a maximum of 10 micrometers, in particular a maximum of 6 micrometers, in particular a maximum of 3 micrometers and/or at least 2 micrometers. The second cover layer 4 is matted in the functional area 6 .

As part of the method, the plastic base component 2 is further processed in particular to the effect that the second cover layer 4 adjacent to the ablation area 5 is partially removed by means of the laser and, for example, in a nominal power range of 15 to 20 watts, in order to form the functional area 6. The second cover layer is roughened and matted in the functional area by the laser processing and/or the laser ablation.

A method step that includes the complete removal of the second cover layer to form the removal area 5 and another method step that includes the partial removal of the second cover layer to form the functional area 6 can also be carried out in reverse order.

In the 3 is the plastic component 1 from the 2 shown as part of a component assembly 10. The plastic component 1 and/or the component arrangement 10 is designed to be arranged on the outside of a vehicle, for example a car. For example, the plastic component 1 as a decorative strip or as an inventory part of a radiator grille of the vehicle, in particular as a radiator protection frame or as a radiator protection grille.

The component arrangement 10 has an illumination device 7 which can generate and emit light 9 . The lighting device 7 is designed, for example, as at least one light-emitting diode. The lighting device 7 is assigned to the plastic component 1 in such a way, e.g. operatively connected to it or attached to it, that the emitted light 9 shines through the translucent plastic base component 2 and through the translucent first base layer 3 and illuminates the ablation area 5, so that a luminous area 8 is formed in the ablation area 5 .

In contrast, the light 9 does not radiate through the second cover layer 4 due to its opaque properties. Functional area 6 is unlit for the same reason.

In the 4a is a plan view of the visible side of the plastic component 1 of the component arrangement 10 from FIG 3 shown. In the second cover layer 4 of the plastic component 1 forming the visible side, the area 5 has been removed, so that the first base layer 3 is visible in the area 5 removed. The ablation area 5 forms a character 11, which in the exemplary embodiment is a rhombus with four sides, in particular with one in the image plane of FIG 4a right, left, top and bottom side is. The ablation area 5 as the sign 11 is in line with that formed by the plastic base component 2 (see 1-3 ) and light 9 passing through the first base layer 3 is illuminated.

The functional area 6 is arranged adjacent to the character 11 on the right and upper side. The functional area 6 is designed to be continuous and/or uninterrupted and partially surrounds the character 11 . It extends almost completely along the right and upper side of the character 11. The functional area 6 forms a shadow 13 of the character 11 in the functional area 6 due to its positioning and in particular due to the matting 12 of the second cover layer 4 and/or creates a three-dimensional effect ( 3D effect) 14 for the character 11. The character 11 is given an optical depth by the functional area 6. In an alternative exemplary embodiment, the functional area 6 can also completely surround the character 11 .

the 4b shows a top view of the visible side of an alternative plastic component 1a of the component arrangement 10. In the second cover layer 4 of the plastic component 1 forming the visible side, several, e.g Functional area 6a, 6b, 6c, 6d, 6e adjacent. The removal areas 5a, 5b, 5c are arranged one after the other in the second cover layer 4 at a distance from one another.

A first ablation area 5a forms the letter P as character 11. Adjacent to sides and/or parts of the first ablation area 5a are a first functional area 6a and a second functional area 6b arranged at a distance therefrom. The first functional area 6a is completely surrounded by a curved section and a vertical section of the P, so that the frosted first functional area 6a in the first completely fills the enclosed area. The second functional area 6b runs along a right side of the P that runs vertically in the image plane and extends continuously along a lower side of the P that runs horizontally in the image plane.

A second ablation area 5b forms the letter O or the number zero as character 11 . The second removal area 5b borders on two further functional areas 6c, 6d in the second cover layer 4, which are independent of one another, namely on a third and fourth functional area 6c, 6d. The third functional area 6c runs in the image plane in relation to the O on the left along a curved inner side of the O and the fourth functional area 6d runs on the right along a curved outer side of the O.

A third ablation area 5c forms the number 7 as character 11. The third ablation area 5c borders on a fifth functional area 6e, which is designed to be continuous and/or uninterrupted. It partially surrounds the character 11 as the number 7 on a right and upper side in the image plane. Each of the functional areas 6a, 6b, 6c, 6d forms a shadow 13 of the respective character 11. Alternatively or additionally, each of the functional areas 6a, 6b, 6c, 6d generates the 3D effect 14 for the respective character 11.

In an alternative exemplary embodiment, a functional area 6 can extend between two of the characters 11, adjoining each of the characters 11 at least in sections.

The ablation areas 5a, 5b, 5c are optionally illuminated by the light 9 of the illumination device 7 (see 3 and 4a) illuminated and form luminous areas 11, which improve the visibility of the characters 11 formed by the ablation areas 5a, 5b, 5c and in particular can intensify the shadow cast 13 and/or the 3D effect.
