Description

The invention relates to a device for masking a component and a device for coating a component, the component being in particular a body part.

If components are only to be partially coated, different techniques are available: selective coating processes or masking of the areas that are not to be coated.

The selective coating processes include, for example, micro-dosing technology, which can be carried out either stationary in the inkjet process or with the help of robots (Dürr, 2021) (ABB, 2021). The challenge with this method lies in the sharpness of the contours in the case of curved or circular surfaces and in the accessibility of the surface to be painted, especially in the case of components with overhanging structures. In addition, web connections (overlapping areas) are clearly visible, depending on the paint system. Particularly in the case of robot-assisted methods, it is very difficult to achieve a high level of path or contour accuracy combined with high positioning accuracy.

When painting geometrically demanding components, selective painting is usually done by covering the areas that are not to be coated. The more complex the geometry, the more care is required for the masking, since even the smallest error can lead to costly corrective measures.

The masking processes must meet the following criteria in particular: easy to use, easy removal of the masking material without residues, ideally suitability for very small to very large areas and complex geometries, chemical resistance to the process and coating materials, physical resistance to all process parameters, and/or cost-effective in terms of material and labor costs.

Conventional masking is usually done with tape ( US5464692 ), self-adhesive films ( US5203944 ), tin or solid metal covers ( US6645299 ), preformed plastic moldings ( WO2010031370A1 ) or the application of “sacrificial materials” in layers (Bachmann AG, 2021). A special form, for example, is the "paste process" ( WO2017081098A1 ).

These masks are generally applied manually. They require concentrated work, but even when used optimally, their accuracy and repeatability is limited.

Handling foil and adhesive tape is very labor-intensive and error-prone. Adhesive tape has to be sticky enough to withstand mechanical stress and at the same time be removable in one piece. Adhesive tape masks and paint-like materials can be used universally, but can only be removed again with great effort, and residue-free removal can only be achieved with certain mask/component material combinations. If adhesive residues remain, these usually have to be removed in a complex manner using mechanical or chemical cleaning processes. The resulting high technical and time expenditure also harbors the risk that the component surfaces will be damaged.

In the case of preformed covers, there are usually high costs, since precisely fitting masks have to be created that have to be replaced or cleaned after a certain number of cycles. Such maskings have the disadvantage that suitable receiving devices for attachment to the component must be present and that the component may be damaged by the attachment and removal of the masking before or after the coating process.

Unmasking is time-consuming and usually contaminates the painted component with paint dust when the mask is removed by hand.

The object of the invention is to provide a device for masking a component and a device for coating a component, the masking of the component to be coated being simplified.

The objects are achieved according to the invention by a device for masking a component according to claim 1 and a device for coating a component according to claim 19.

After the component has been fed in, the component is preferably coated, in particular painted.

In a preferred embodiment, the step of removing the component from the component holder also takes place. If the component is coated after the component has been supplied, for example as part of the method for coating a component described below, then it is preferable for the coated component to be removed during the step of removing the component. The removal results in particular in the unmasking of the component, since the connection between the component and the film is released. After the component has been removed from the component holder, the film is preferably removed, in particular partially, from the holder area. In this case, in particular, a foil section of the foil is removed. Particularly preferred is the film section that is in the optional Coating step, e.g. as part of the method described below for coating a component, was removed. The foil section used in this coating step, which was used at least partially for masking, is usually contaminated with coating agent and is therefore in particular removed. After the component has been removed, in particular after the film has been removed, the film is in particular arranged again over the receiving area.

In a preferred embodiment, when the film is arranged again over the receiving area, a further film section, preferably different from the first, is arranged over the receiving area.

In a preferred embodiment, the film is arranged over the receiving area and/or the film is arranged again over the receiving area and/or the film is removed from the receiving area by advancing the film. The film is particularly preferably carried on by a rolling process.

1 shows an embodiment of the device 10 according to the invention for masking a component 100.

The device 10 has a component receptacle 12 with a cavity, the cavity shown forming a receptacle area 16 for a component 100 to be masked and preferably coated. The component holder 12 is connected to a base plate 54 by means of feet 52 .

The component receptacle 12 has a contact region 30 on which the component 100 to be masked and preferably coated, in particular with an outer area of the component 100, is arranged. The component receptacle 12 has a fixing device 32 opposite the contact region 30 .

When the component 100 is received in the component receptacle 12 , the contact region 30 is arranged on one side of the component 100 and the fixing device 32 is arranged on the other side of the component 100 . The fixing device 32 fixes the component 100 in the component holder 12. For fixing, the fixing device preferably presses the component against the receiving area 30. It is preferred that the fixing device 32 is designed to be expandable, e.g exert on the component 100.

Projections 34′, 34″ are shown arranged within the receiving area 16 of the component holder 12. The projections 34′, 34″ are designed in particular to fill openings 106′, 106″ and/or depressions in the component 100. The projection 34′ is shown. in particular expandable, e.g. can be filled with air, in order to define the contour of the opening 106' (see 2 ) to be filled in tightly. Projection 34" is shown to fill opening 106" (see Fig 2 ) of the component. Preferably, the projection 34" is rigid. It is preferable for the projection 34" to be movable. For example, it is possible for the projection 34'' to be designed such that it can be moved up and down.

A film 14 is stretched over the component holder 12, which covers the receiving area 16, the entire component holder 12 shown (the stretched section of the film 14 is hidden in the figure; cf. dashed lines). The film 14 is a film strip that is partially rolled up. In the embodiment shown, the foil section 20 with the length L is stretched over the component holder 12 . The foil 14 is in particular an adhesion foil.

The foil 14 is provided by a foil supply device 18 . The foil supply device 18 is shown as having a feed roller 22 and a discharge roller 24 . The film 14 , in particular the film section 20 , is clamped between the feed roller 22 and the discharge roller 24 . The film 14 can be continued (shown in the direction of arrow 56). The film 14 is fed on by driving the discharge roller 24 by means of a motor 26 , the film 14 being rolled onto the discharge roller 24 and unrolled from the feed roller 22 . The feed roller is braked in particular by means of a braking device 50 . By means of a motor 26 and a braking device 50, it is preferably implemented that the film 14 is kept under tension. In particular, the braking device is adjustable in order to set a predefined tension of the film 14 .

It is preferable for the device 10 to have a sensor system (not shown) and/or an automatic system in order to advance the film 14 in a defined length. It is particularly preferred that the sensor system and/or automatic system is designed to continue the film by the length L, i.e. in particular by a film section 20 of the film 14. After the film 14 has been advanced, a new film section 20 is thus in particular over the component receptacle 12 stretched.

The sensor system preferably has at least one sensor. The at least one sensor is designed in particular to detect the film 14 that has already been fed in and/or to detect the remaining amount of film 14 .

The feed roller 22 is movably mounted in feet 46 . The discharge roller 24 is movably mounted in feet 48 . The feet 46, 48 are connected to a base plate 54.

The component holder 12 and the film supply device 18 are shown arranged on a base plate 54 . On the other hand, for example, an arrangement directly on a floor is also possible.

In 1 a component 100 to be coated is also shown before it is placed in the component holder 12 . The component 100 is preferably a body part for a passenger car, particularly preferably a front panel.

The component 100 is preferably supplied by means of a component guide (not shown) having a robot arm.

The component 100 has a first side 102 to be coated and an opposite side 104 (see FIG 3 ) that should not be coated. The first side 102 to be coated is connected to the side 104 not to be coated via a connecting area, in particular a connecting surface.

When the component 100 is inserted into the component receptacle 12, the side 104 of the component 100 comes into contact with the foil section 20 of the foil 14, as a result of which the side 104 of the component 100 is masked. In this case, the film 14 nestles against the component contour and connects, preferably adhesively, to the component. When component 100 is inserted, component 100 is thus automatically masked.

The film 14 is preferably arranged between the component receptacle 12 and the side 104 not to be coated. In particular, the foil 14 is arranged in such a way that the foil 14, preferably in the case of the component 100 arranged in the component receptacle 12, is in contact with at least a partial area of the side 104 not to be coated and/or in contact with at least a partial area of the connection area of the component 100 .

Furthermore, when the component 100 is inserted into the component holder 12, part of the film 14 is arranged between the component 100 and the component holder 12, in particular clamped between them. In particular, part of the film 14 protrudes beyond the component receptacle 12 .

This arrangement of the film 14 in the device 10 thus results on the one hand in the component 100 being masked, so that parts of the component 100, in particular the side 104, are not coated (see FIG 4 ). On the other hand, the component holder 12 is at least partially, in particular completely, shielded from an applied coating agent 60 by the film 14 (see FIG 4 ). In particular, the base plate 54 and/or the base on which the device 10 is arranged is also shielded. Thus, there is no contamination or soiling of the component holder 12 and/or the base with coating agent.

2 FIG. 12 shows a side view of the device 10. FIG 1 .

3 Fig. 12 shows a sectional view of the section plane A1-A1 2 .

The component 100 is placed in the component holder 12 (see arrow 56) so that it comes into contact with the side 104 with the film section 20 (shown as a dashed line) of the film 14 and is thus masked. The openings 106', 106" of the component 100 (cf. 1 ) are taken up by the projections 34', 34".

4 10 shows a device 11 for coating a component 100 with the device 10 1 with inserted component 100 during a coating process. The side 102 of the component 100 to be coated can be seen, with the masked side 104 not to be coated being opposite (cf. 3 ).

An outer area 62 of the component 100 lies with the side 104 on the contact area 30 (in 4 not shown; please refer 1 ) of the component holder 12. After insertion, the expandable fixation device 32 is filled with air, for example, and thus expands. The expansion of the fixing device 32 results in a positive fit of the component 100 in the receiving area 16 of the component holder, with the outer area 62 of the component 100 on the side 102 being pressed by the fixing device 32 with the side 104 against the contact area 30. This results in the component being fixed and in particular in a sealed connection between component 100 and film 14, so that no coating agent 60 can reach the masked side 104 of the component that is not to be coated. The fixing device 32 is designed in particular as a hose element, preferably as an elastomer hose.

A film section 20 of the film 14 is arranged between the component 100 and the component receptacle 12 (cf. dashed lines).

In addition to the device 10 for masking a component 100 , the device 11 for coating a component 100 has 4 also a coating device 44 shown schematically. A coating agent 60 is applied to the side 102 of the component 100 by the coating device 44 , which has a robot arm 42 . The coating agent 60 is, in particular, paint.

By masking page 104 (cf. 3 ) of the component 100 with the film 14 no coating agent reaches the side 104. Furthermore, the arrangement of the film 14 shields the component holder 12 from the coating agent 60, so that the component holder 12 is not exposed to the coating agent 60.

The 1-4 an embodiment of the method according to the invention can also be found accordingly.

1 shows, for example, the arrangement of the film 14 over the receiving area 16 of the component holder 12. 3 shows, for example, the feeding of component 100. 4 shows, for example, the coating of component 100. After the coating of component 100 (see e.g. 4 ) In particular, the component 100 is removed from the device 10. Then, in particular, the film 14 is conveyed further (see arrow 56 in 1 ), it being preferred that the foil is extended by the length L (see 1 ) is continued, so that a new film section 20 is arranged over the receiving area 16 . The process can then be repeated once or several times with other components to be coated. It is also possible to repeat the method, at least once, with the component that has already been coated, for example in order to apply a further layer of coating agent.
