Description

technical field

Various examples of the invention relate to techniques for storing components, and more particularly to techniques for a cradle for storing components in a process chamber.

background

3D printing processes are additive manufacturing processes in which a component is built up in layers, in particular using a plastic. Such additive manufacturing processes have the disadvantage that the components produced with them usually do not have a closed surface, i.e. a production-related rough surface, which in many cases can have a negative effect on the haptic impression of the user of the component. In addition, a rough surface of such a component tends to get dirty relatively quickly, with cleaning of the surface only being possible with considerable effort. In addition, the surface of such components has a large number of pores due to the production process.

In order to smooth the surfaces of the components produced using a 3D printing process, the surfaces can be machined, for example ground and/or blasted. The disadvantage here, however, is that material is removed from the surface of the component, albeit small, which is usually above predetermined tolerance values to achieve the desired surface smoothness, so that smoothing the surface is accompanied by an undesirable change in the geometry of the component. In addition, areas of the surface that are concave or have undercuts, in particular with small radii of curvature, can only be mechanically smoothed with great effort or not at all. In the case of very filigree surface structures, there is also a risk of damage during grinding or blasting. Furthermore, pores present on the surface are only insufficiently closed even when grinding or blasting.

Various methods for smoothing components are known. In addition to thermal smoothing, for example explosion smoothing, methods for chemically smoothing components are also known. Here, the surface of the component is partially dissolved by suitable solvents and then hardens again by removing the solvent. Particularly relevant is the smoothing by vaporization of plastic components, in which a solvent vapor is applied to the surface of the plastic part for a predetermined period of time. A process chamber and the support frame (also a mount or rack) on which the components are placed are each brought to a predetermined temperature between -100 °C +250 °C. In this case, the carrier frame can already be in the process chamber or can be brought up to temperature outside before it is introduced into the process chamber. A solvent is then introduced into the process chamber as a vapor, with the solvent condensing on the surface of the components due to the lower temperature of the components. The solvent condensate forming on the surface of the component can be controlled with the aid of a negative pressure in the process chamber and a temperature difference between the components and the solvent vapor and the duration of the solvent supply, whereby partial dissolution of the surface of the components can be controlled. As a result, surfaces of the components can be smoothed without there being any significant changes in the geometry of the components.

Existing smoothing systems with comparatively high temperatures use wires or metal hooks to thread the components. It is also known to design and print additional hooks or eyes for attachment to the components. Then the parts can be hung on it, and the hooks/eyelets can be broken off after the process, for example, or remain on the part if placed in an inconspicuous place.

By dissolving the surface of the components, the process can sometimes leave clear traces on the components, which can be caused by mechanical pressure or stress on the components and shielding effects from the solvent vapor due to the storage of the components. In addition, the different thermal capacities of the component and the support frame can mean that the amount of solvent condensate that forms on the components can be difficult to control. Condensed solvent on the support frame can drip onto the components in the form of hot drops, which can be detrimental to a homogeneous smoothing result.

Brief Summary of the Invention

Therefore, there is a need for improved techniques for supporting components in a process chamber that overcome or mitigate at least some of the limitations and disadvantages noted.

This object is solved by the features of the independent patent claims. The features of the dependent claims define further advantageous embodiments.

A support frame for storing, or holding, or fixing components comprises a base frame and at least one storage device which is attached to the base frame or is detachably attached to store components.

The support frame can be of modular design, with various modular storage devices being able to be attached to the base frame. For example, a first bearing device can be attached to the base frame, which corresponds to a first component type, wherein the first bearing device can be exchanged for a second bearing device which is different from the first bearing device and corresponds to a second component type. For example, two or more different storage devices can be attached to the base frame at the same time, which correspond to different types of components. In some examples, the support frame may comprise 2, or 3, or 4 different storage devices that have a different shape and/or at least one different component. For example, the storage devices can have the same components which are detachably connected to the base frame.

In some examples, the support devices may differ in that they have different shapes, or in that one support device has rigid, optionally rod-shaped, components for supporting the components and no flexible elements, and that another support device has flexible, elastic or inelastic, components has for storing the components.

The base frame can define or comprise an outer shape of the support frame, in particular the outer surfaces or outer edges of the support frame. For example, the elements that make up the base frame, such as rod-shaped or elongated elements, cannot be used to store components. In general, the support frame, the basic structure, and the storage devices can each comprise a large number of elements connected to one another, or can each be constructed integrally from one element. In some examples, the base frame and/or one or more storage devices and/or individual elements connected, in other words fastened or attached, to the base frame can be permanently or detachably attached, for example laid on, clamped or pushed in.

The base frame can have at least one fastening arrangement, which is optionally attached to an inside of the base frame. The at least one storage device can be designed as an insert or slide-in unit and can be attached to the attachment arrangement within the base frame in a non-destructive, detachable manner.

In some examples, the mounting arrangement comprises at least one horizontal guide rail, or a pair of guide rails, and the storage device is designed as a slide-in unit that can be slid into the base frame along the at least one guide rail.

In some examples, a storage device may include rigid components configured to store components. In some examples, a storage device may include flexible components configured to store components. In some examples, the storage device may comprise rigid components which form a frame in a horizontal plane, and in which frame is mounted a flexible, optionally inelastic, mesh fabric, preferably of glass fibre, carbon fiber or plastic fibre, on which components can be supported, more preferably an elastic mesh fabric.

The support frame can at least partially have a surface coating. The base frame and/or rigid components and/or flexible components can have a surface coating partially or completely.

A technical system, for example a processing system or a vapor deposition system, in particular for smoothing components, includes a housing, a process chamber that is formed in the housing, and a support frame for storing components in the process chamber according to the present disclosure.

The techniques described herein provide an improved component fixture that is simultaneously modular and allows loading of a variety of different types of components of different sizes, shapes or materials. The support frame thus provides a modular, flexible system with solvent- and temperature-resistant rigid and flexible components, with optional coating for a large number of component geometries, which can be adjusted to different components with simple operation, with deformations and imprints on the components being minimized will. In addition, the different thermal capacities of the component and the support frame make it difficult to control the amount of solvent condensate that forms on the components.

The features set out above and features described below can be used not only in the corresponding combinations explicitly set out, but also in further combinations or in isolation without departing from the protective scope of the present invention.

Detailed Description of Embodiments

The properties, features and advantages of this invention described above, and the manner in which they are achieved, will become clearer and more clearly understood in connection with the following description of the exemplary embodiments, which are explained in more detail in connection with the drawings.

In the figures, the same reference symbols designate the same or similar elements. The figures are schematic representations of various embodiments of the invention. Elements depicted in the figures are not necessarily drawn to scale. Rather, the various elements shown in the figures are presented in such a way that their function and general purpose can be understood by those skilled in the art.

In the following, techniques are described in connection with a support frame, in other words a frame or a storage or holding device, for storing or holding components, in particular for storing additively manufactured molded parts (e.g. 3D-printed plastic molded parts) in a process chamber of a technical Systems, such as a vapor deposition system. The techniques described can be used in particular for smoothing components, for example thermal smoothing of components, for example explosion smoothing, or for chemical smoothing of components. It is to be understood that the method according to the invention is not limited to these methods, but can be used for a large number of methods or processes for processing components in a process chamber, in particular with precise control of a temperature profile and/or condensation on components in the process chamber can be critical to the quality of the process.

3D printing processes are additive manufacturing processes in which a component is built up in layers, in particular using a plastic. Such additive manufacturing processes have the disadvantage that the components produced with them usually do not have a closed surface, i.e. a production-related rough surface, which in many cases can have a negative effect on the haptic impression of the user of the component. In addition, a rough surface of such a component tends to get dirty relatively quickly, with cleaning of the surface only being possible with considerable effort. In addition, the surface of such components has a large number of pores due to the production process.

In order to smooth the surfaces of the components produced using a 3D printing process, the surfaces can be machined, for example ground and/or blasted. The disadvantage here, however, is that material is removed from the surface of the component, albeit small, which is usually above predetermined tolerance values to achieve the desired surface smoothness, so that smoothing the surface is accompanied by an undesirable change in the geometry of the component. In addition, areas of the surface that are concave or have undercuts, in particular with small radii of curvature, can only be mechanically smoothed with great effort or not at all. In the case of very filigree surface structures, there is also a risk of damage during grinding or blasting. Furthermore, pores present on the surface are only insufficiently closed even when grinding or blasting.

Methods for smoothing plastic components by vapor deposition are also known, in which a solvent vapor is applied to the surface of the plastic component for a predetermined period of time. A process chamber with a support frame (also called a holder or rack) on which the components are placed is brought to a predetermined temperature between -100 °C +250 °C. A solvent is introduced into the process chamber as a vapor, with the solvent being able to condense on the surface of the components due to the lower temperature of the components. The solvent condensate forming on the surface of the component can be controlled with the aid of a negative pressure in the process chamber and a temperature difference between the components and the solvent vapor and the duration of the solvent supply, whereby partial dissolution of the surface of the components can be controlled. As a result, surfaces of the components can be smoothed without there being any significant changes in the geometry of the components.

In combination with the dissolving of the surface of the components, the process sometimes leaves clear marks on the components at the points of contact of recording and components, which are caused by mechanical pressure on the components. Other irregularities may arise from solvent vapor shielding effects caused by the support structure. In addition, the amount of solvent condensate forming on the components is difficult to control due to additional condensates on the support frame. Condensed solvent on the support frame can drip onto the components in the form of hot drops, which can be detrimental to a homogeneous smoothing result.

As a general rule, different devices can be processed using the techniques described herein. In one example, additively manufactured components could be processed from a metal or a plastic. It would also be conceivable to treat plastic parts that are obtained in an injection molding process. It would also be conceivable to treat plastic components that were produced using a 3D printing process, for example a powder bed process. The components, which are produced in a powder-based manufacturing or printing process, can be made from a material selected from the group comprising polyamide, in particular polyamide 6, polyamide 11 and polyamide 12, thermoplastic polyurethane, aluminium-filled polyamide, in particular aluminium-filled polyamide 12 , glass-filled polyamide, carbon-reinforced polyamide, polypropylene, sand, gypsum, metal, composite, and combinations thereof. An example of a powder bed process would be a selective laser sintering (LS) process, in which the body of the plastic component is built up step by step. After completing such a 3D printing process, it is then necessary to separate the plastic components from a powder cake. It would also be conceivable to treat plastic components that have been produced by a fusion-lamination 3D printing process, for example by means of fused deposition modeling (FDM) or fused filament fabrication (FFF).

1 FIG. 12 schematically illustrates a carrier frame 10 with various storage devices 30 according to some exemplary embodiments.

As in 1 1, a modular storage system is provided with a plurality of different storage devices 30 (in other words, storage tiers, trays, or drawers, for storing components) integrated into a basket-like base 20. The storage planes 30 run essentially horizontally in the horizontal direction and can be pushed into the base frame 20 and pulled out. Components can thus be easily placed on the storage levels 30. It is also conceivable to design storage levels and corresponding fastening devices in the base frame for vertical insertion.

The storage levels 30 mechanically engage in fastening devices 40 which are fastened, for example, on an inside of the base frame 20 . In the example of 1 the fastening devices 40 each comprise rod-shaped fastening or guide elements, in other words guide rails, which are attached internally on two opposite sides of the base frame. Thus, the storage planes 30 can rest on the guide elements 40 and can be displaced on them. In some examples, the storage devices 30 can be detachably connected to the fastening devices 40, for example by means of rigid locking elements which fix the storage device in a tilt-proof manner in the fully inserted state or in an extended state. In one embodiment of the invention, the fastening devices 40 could also be made from less material, for example from three or four pieces, for example from short pieces of wire, for example about 10 mm long. In this case, the storage planes would only rest on the fastening devices 40 on the base frame 20 at three or four points.

For example, it is conceivable that individual storage levels 30 are designed in such a way that they correspond to the components to be processed, with the components being able to be placed outside of the base frame 20 on a corresponding storage level 30 that fits, and can be inserted into the base frame together with the components. These include the storage devices in the 1 different rigid elements. Instead of being laid on, components can also be hung, clamped or wedged in other configurations of the storage levels.

The top in 1 The storage device 30 illustrated comprises rod-shaped rigid components which thus form a frame which engages the fastening device 40 and within which are fixed rod-shaped rigid components 31 which have hooks onto which components can be fastened.

The middle in 1 The storage device 30 shown also includes a frame which can be connected to the fastening devices 40 . Bushings are attached to the frame through which flexible components can be passed and tensioned. In the 1 flexible hoses were fed through two passages each and fastened in the passages using small elements. The flexible elements can have different tensions, so that components can be stored on them.

the lower in 1 The storage device 30 shown also comprises a rigid frame, a flexible mesh fabric having been further fixed within the frame, which in the example fills the entire inner surface of the frame. It is also conceivable that a flexible mesh fabric only fills part of the frame, or is supported by other flexible or rigid elements. In the example of 1 the flexible mesh has a surface coating of non-stick and thermally insulating material. The camp operations 1 can be interchanged or removed at will.

It is conceivable that the storage levels 30 have different, optionally at least two different, vertical distances from one another, so that enough space is reserved in the base frame 20 for different component sizes. Correspondingly, different horizontal distances between the levels can be realized in the case of vertically inserted storage levels. It could be possible, for example, to provide between two and ten fastening elements, between three and five have proven to be advantageous. Between two and ten or between three and five storage levels can then be used during a process.

Optionally, the entire system or individual storage devices 30 are provided with an insulating and/or non-stick coating. A combination with coated hooks or suspension with cords/wires etc. made of a material with low heat capacity/thermal conductivity/high insulating ability/low adhesion can be advantageous, as will be described in more detail below.

In addition, several vertically running struts are attached to the side surfaces on which the fastening devices 40 are attached, which take up the weight of the storage planes 30 used and, if necessary, the components placed on them. The number and design of the struts can be varied depending on the desired stability of the basic structure.

It can be advantageous to minimize a number of components of the base frame, so that a heat capacity of the carrier frame 10 is minimized overall. A base frame can be designed in such a way that it defines an outer shape of the support frame, for example the outer shape can have the shape of a cuboid or a cylinder. In other words, the base frame 20 can define all of the outer surfaces of the support frame. In this regard, a base frame 20 may be configured such that it is configured only to support the storage tiers 30 , with components not being placed directly on the base frame 20 . It can be advantageous here that the base frame 20 only contains elements which run in an outer contour, and therefore in the outer surfaces of the base frame 20 . It can be particularly advantageous if these elements run exclusively along the outer edges of the base frame 20 and/or, for example, only connect outer edges or corners of the base frame.

In addition to reducing the components to reduce the heat capacity (and the weight) of the base frame 20 and the storage levels 30, this can also be done by selecting the semi-finished products. The diameter of the wires can be selected accordingly, for example between 2 mm and 6 mm, preferably between 3 mm and 4 mm, or hollow tubes or profiles, for example U-profiles, can also be selected instead of solid wires.

When selecting the semi-finished products and designing the components, care can be taken to avoid horizontal surfaces because puddles of solvent can accumulate on the surfaces during the process, which can make suction and drying more difficult.

2 schematically illustrates the base frame 20 of FIG 1 , according to some embodiments.

As in 2 to see, the base frame 20 consists of several elements. The base frame 20 has accommodation options, ie attachment arrangements 40, for storage levels and/or other components.

These other components can have different shapes and configurations. For example, other rigid and/or flexible components may be releasably attached to the base frame, i.e., inserted or slid in, and one or more storage devices 30 may be attached to the base frame 20.

The storage devices 30 can, for example, have a rigid frame, which essentially corresponds to a base area of the base frame 20, and can also include other rigid and/or flexible components, which can be arranged in the frame, and of which some regarding 3 until 7 be described in more detail.

Examples of rigid components may be a (storage) plane (or generally insert or drawer) of wire mesh, a plane of glass fiber mesh, or carbon fiber mesh, or synthetic fiber mesh, or (glass) fiber plastic composite, or carbon fiber reinforced plastic, a level with hooks, rods that can be placed, for example, curved levels (to make full use of the space in a round process chamber), individual hooks that can be hung in the base frame, clamps, rods, needles or nail beds, rod-shaped elements with a round or curved bearing surfaces.

3 12 schematically illustrates a support frame 10 with a storage device 30 with rigid components 31 and hooks, according to some embodiments.

As in 3 to see, the base frame 20 of the support frame 10 corresponds essentially to the base frame 20 of FIG 1 with the fastening devices 40. A storage device 30 with rigid components 31 and hooks is fixed in the base frame 20 by inserting or fixing the frame of the storage device to fixing elements on the fastening devices 40.

4 schematically illustrates the support frame 10 of FIG 3 with storage device 30 extended, according to some embodiments.

In 4 the storage device 30 is at least partially pulled out of the base frame 20, the frame of the storage device 30 being securely fixed by hook-shaped fixing elements on the fastening elements 40. In this way, the storage device 30 is fixed in the extended state on the basic structure so that it cannot tilt and is thus held in a stable manner, so that components can be easily attached to the rigid components 31 with hooks.

How further in 4 As can be seen, several rod-shaped rigid components 31, as elements of a storage level 30, extend from a front side to a rear side of the storage level 30. Several hooks are attached to the rod-shaped components 31, from which components can be hung.

5 FIG. 12 schematically illustrates a carrier frame 10 with two storage devices 30 with a surface coating, according to some exemplary embodiments.

The base frame 20 in 5 essentially corresponds to the base frame 20 of the previous one 1-4 , wherein the base frame 20 provides a plurality of fastening devices 40 for different storage levels 30.

In 5 two storage devices 30 are mounted in the base structure 20, which have a surface coating. The upper storage device corresponds to the storage device 3 and 4 with rigid components 31 and hooks. A lower storage device 30 has a rigid frame, within which frame is mounted a rigid grid, ie rigid rod-shaped components, on which components can be stored.

The bearing devices 30 additionally have a surface coating that thermally insulates the material of the bearing device 30 from the process chamber and has an anti-adhesive property with respect to a solvent and the components in the process chamber.

6 12 schematically illustrates a support frame 10 having a flexible tube storage device 30, according to some embodiments.

The positioning device 30 has a rigid frame which is detachably attached to the base frame 20 . Flexible hoses are stretched within the frame, on which or to which components can be attached.

For example, it is conceivable that larger components are placed on the hoses, with individual pressure points with high pressure on the components being able to be avoided due to the flexibility of the hoses. Due to the flexibility or elasticity of the hoses, a solvent can better wet all areas of the component. Due to a cavity in the hose, the hose has a lower heat capacity than, for example, a cord with the same diameter. In addition, the hose has improved flexibility and elasticity due to the hollow space, since, for example, the hollow space can be at least partially deformed when a component rests on it, and thus can contribute to improved elasticity flexibility.

Two bushings are attached to the frame in order to fasten or tension a hose within the frame. In each case, the tube is passed through a passage and clamped by clamping elements within the passage. For example, such clamping elements can be wedge-shaped elements or screws, in particular grub screws, which are screwed into a passage and thereby reduce a diameter of the bushing.

7 12 schematically illustrates a carrier frame 10 with rigid components 31 for storing components, according to some exemplary embodiments.

On the top mounting assembly 40 of the base frame 7 two wavy rigid components 31 are attached to which components can be placed. example of 7 individual rigid components 31 can therefore also be placed or fastened to the fastening devices 40 instead of position arrangements with frames.

8th FIG. 12 schematically illustrates a carrier frame 10 with different storage levels with rigid and flexible components 31 on which components are stored, according to some exemplary embodiments.

The support frame 10 in the 8th has a lower storage level 30, the surface of which is formed from a flexible fabric on which components are placed. A second storage level with rigid components 31 is also shown, which have hooks on which a component is suspended. The right-hand component is suspended from a flexible PTFE tube 32 which is attached to the framework.

In general, components can have printed hooks or eyes, for example. For example, a foot or floor plate can be printed on to be able to put parts down, since impressions on the underside can be irrelevant.

In general, storage levels may have surfaces and/or components along the storage surface extending within the base that are non-horizontal, e.g., domed upwards, or sloping to one side or from a center to multiple sides. For example, at least one element that runs along a support surface can slope outwards in the direction of the base frame, or in the direction of a center or another predetermined location. It can thus be avoided that, during a smoothing process, solvent condensate on the storage levels on or above the surface of a storage level below it drips onto components and impairs the quality of the smoothing of the components.

For example, a large number of components can be manufactured in a cohesive manner, for example printed together. An area formed by the connected parts can correspond to the base area of the base frame or correspond to an area of a storage level. Further elements can be envisaged which are removed (i.e. broken off or cut off) after the process or a suspension can be provided which does not interfere with traces of the suspension.

It should be understood that any specific feature described and shown for a support structure in relation to a particular embodiment, such as a bearing assembly or rigid or flexible component, can be combined with features of any other support structure, such as a bearing assembly or rigid component or flexible components described or shown in relation to another embodiment, for example another figure.

• Materialien des Trägergestells, des Grundgestells, der starren Komponenten und der flexiblen Komponenten können eine Steifigkeit aufweisen, so dass das Gewicht eines oder mehrerer Bauteile getragen werden kann, beispielsweise im Fall eines metallischen Gestells das Material ein Elastizitätsmodul von größer 50 GPa, vorzugsweise größer 100 GPa, beispielsweise etwa 210 GPa aufweisen. So kann beispielsweise im Fall eines Kunststoffgestells, und/oder flexiblen/elastischen Materialien, ein Material ein Elastizitätsmodul von größer 0,1 GPa, vorzugsweise größer 1 GPa, weiter vorzugsweise größer 10 GPa, beispielsweise etwa 420 GPa (PTFE) aufweisen.

Some general conclusions can be drawn from the above:

• Materials of the support frame, the base frame, the rigid components and the flexible components can have a stiffness so that the weight of one or more components can be carried, for example in the case of a metallic frame the material has a modulus of elasticity of greater than 50 GPa, preferably greater than 100 GPa , for example about 210 GPa. For example, in the case of a plastic frame and/or flexible/elastic materials, a material can have a modulus of elasticity greater than 0.1 GPa, preferably greater than 1 GPa, more preferably greater than 10 GPa, for example about 420 GPa (PTFE).

Furthermore, the material or materials of the support frame and/or the base frame and/or the rigid components and/or flexible components of a storage device can exhibit temperature resistance at least in a specific temperature range.

In some examples, the temperature range may have an upper limit of at least 50°C, at least +100°C, preferably at least +140°C, or at least +160°C, or more preferably at least +300°C.

In some examples, the material may exhibit solvent resistance, optionally in any of the above temperature ranges. In some examples, a thermal conductivity and/or a heat capacity of the material may be lower compared to steel.

However, depending on the temperatures that prevail during the process, materials with lower temperature resistance can also be used.

In some examples, at least one or more of the base frame, the storage device, the rigid components, and the flexible components may include at least one element made of one of the materials described, or made of a combination of the materials described.

For example, the support frame and/or the base frame and/or the rigid components and/or the flexible components could not all be made from the same material, but rather from different materials from the materials described. For example, the base frame could be made of stainless steel and the bearing devices that could be used could be made of one of the composite materials mentioned, and the rigid and/or flexible materials that come into contact with components could be made at least partially of PTFE. Thus, a material of the base frame can have a higher strength than a material of a storage device, and this higher strength than a material of a fixed or flexible component for the storage of components. It is also conceivable that the elements mentioned have greater flexibility or elasticity in this order.

In some examples, one of the base frame and the rigid components and the flexible components can be made of at least two specific materials from those described forming a composite material.

In some examples, one of the base frame and a component and a flexible component can be combined from a specific combination of one or more materials with one of the surface coatings.

A fixation of the storage level can also be omitted or achieved by other features, for example by hooks, stops, clamps or increased friction.

It is understood that the techniques according to the present disclosure may be limited to any subset of the described materials. It is further understood that a list of materials is not exhaustive, and other materials that meet the stated requirements are possible.

The base frame can be designed in such a way that it only has components which are designed to support the at least one storage device and are not designed to store components, the components of the base frame preferably only running along the outer surfaces and/or the outer edges of the base frame .

For example, it is conceivable that at least one or more of the base frame and the rigid components and the flexible components contain at least one element that is hollow. In other words, having at least one cavity extending at least partially in an interior of the element. Optionally, the cavity is connected to the atmosphere of the process chamber through at least one opening.

For example, it is conceivable that a material with a large number of cavities, for example a honeycomb structure or with a number of partitions between individual cavities, is used, as a result of which mechanical stability can be increased and thermal conductivity and thermal capacity can be reduced. For example, rod-shaped elements with one or more cavities can have increased stability with a lower heat capacity.

In one embodiment of the invention, cavities could also be used to connect elements in a modular manner, for example via a plug-in mechanism. A flexible element, for example a PTFE hose, could optionally be fixed in a hollow space, for example a piece of pipe, for example with a further rigid element such as a threaded pin (grub screw).

The support frame and/or the base frame and/or the rigid components and/or the flexible components can have, for example, a surface coating, i.e. a non-stick layer and/or with a heat-insulating layer, optionally at least partially, i.e. at least one element or one surface with a have such a coating.

The surface coating or surface layer can be applied in various ways. e.g. as shrink tubing or as a coating, for example by fluidized bed coating, spray coating or dip coating.

Ranges from 1 μm to 2 mm, 50 μm to 2 mm, 50 μm to 500 μm, 200 μm to 2 mm, more preferably 500 μm to 2 mm, are also possible as layer thicknesses, for example. Where higher layer thickness results in better insulation (i.e. ther mixing leads to insulation) of the coated element, thus enabling lower thermal conductivity and reduced solvent condensate on the element. The thickness of the coating should be selected according to the thermal capacity of the support frame and can also be less than 1 µm for thermally insulating materials. In some examples, with suitable base materials, eg, core materials having a thermal conductivity or heat capacity comparable to surface coating materials, no further coating may be required.

Examples of flexible components can be cords, hoses, nets or braids, woven mesh or more generally lattice structures, ie with regular openings that can be permeable to solvents and, for example, have a size of >2 mm ² , or >5 mm ² , or >10 mm ² can have. For example, flexible fiberglass mesh or carbon fiber mesh or synthetic fiber mesh can be used. For example, flexible webs may be in tension (pre-tension) between attachment points, or may be placed without tension. Furthermore, the flexible components mentioned can be constructed from hoses which have at least one hollow space in their interior, similar to that described for the rigid components. Band structures, ie bands made of one of the materials with a (possibly cuboid cross-section) with a width that can be greater than their thickness by a factor of at least 2, 5, 10 or 20, can be particularly advantageous. Furthermore, the flexible components mentioned can be constructed from coated wires, for example from a metallic core and an anti-adhesive or insulating (enveloping) layer, ie coating. Flexibility with simultaneous dimensional stability would be advantageous in this configuration. Dimensional stability in the sense that a wire remains in the bent shape after being deformed or bent.

It is conceivable that the flexible, as well as the rigid, components on which components are supported include spacers. The spacers may be connected to the flexible components, or may have openings through which the flexible components pass. The spacers can be fixed to a flexible component, or they can be moved. As a result, the components that rest on the rigid or flexible components can be better separated from one another and, in some cases, can be fixed more stably on the carrier frame. In particular, spacers can prevent the components from touching one another and thus prevent components from sticking together during the machining process.

Flexible components (such as cords) may have features to attach to rigid components, e.g., loops, eyes, hooks of various materials.

In addition, features may be implemented on the rigid components that allow attachment of the flexible components, e.g. hooks, holes, pins, magnets, clamping possibilities (such as between the coils of a spiral spring.

Flexible components to which multiple components are to be attached may have separators or spacers included or added during loading of the basket to prevent components from touching, such as discs, nodes, spacers.

The support frame itself can be 3D printed, for example using a material that is resistant to the solvent and temperature stable (e.g. PEEK).

The support frame could be made of PTFE core reinforced with carbon fiber or glass fibre, i.e. a carbon/glass fiber composite material with non-stick or thermally insulating properties, or with an appropriate surface coating. For example, the support frame can be made without carbon fibre, i.e. as a pure plastic frame, optionally with supporting carbon (cross) struts, whereby in some examples a surface coating can be dispensed with.

Within an insert, cords/hoses could be fixed by means of sleeves + grub screws, for example made of plastic with a wing nut, generally by means of a fastening element which provides clamping. Any two components or elements can be connected by means of a press-fit or snap-fit.

The support frame and/or the rigid components and/or the flexible components could be made from tubes, which could be injection molded or milled, for example, or made from semi-finished products, for example rods or tubes, e.g. made of PTFE, with the low thermal capacity of PTFE Even with a large contact surface, there are no imprints on the components. The tubes could be reinforced with internal rods (e.g. CFRP).

The techniques described are based on the knowledge that the fact that the surface of the components that are processed in the process chamber is partially dissolved means that the components should not touch or should have a small contact surface on the carrier frame. However, if the contact surface is too small, more pressure and/or heat can act on the components, which can result in imprints on the components. It is therefore desirable, based on a component-specific consideration, to be able to flexibly adapt a mounting of the components, in particular a number and area of contact points with a carrier frame, to the components. Mounting components on flexible components that have a low heat capacity can be particularly advantageous. For example, components can be mounted particularly advantageously on a mesh fabric or a net made of PTFE, PTFE tubing or a fabric made of glass fibers or carbon fibers or plastic fibers, hollow fibers, which are coated with a non-stick coating made of PTFE, for example.

Some examples may include rigid and/or flexible components, which may have an air cavity, and/or be made of a material comprising glass fibers or carbon fibers, and/or have a non-stick and/or thermally insulating surface coating.

For example, it is conceivable that the support frame and/or its components are made at least partially from a profile that can be produced in an extrusion process.

A heat capacity in the process chamber, which is provided by the support frame, can thus be minimized, as a result of which less solvent unintentionally condenses in the process chamber.

In some examples, it is envisaged that attachment assemblies for inserts will be attached directly to walls of the process chamber, in other words not using a base frame that is inserted into the process chamber to insert inserts or drawers into the process chamber. In such examples, the support frame consists only of an insert, or insert and corresponding fastening element, which can have the shapes described and which can be made of the advantageous materials described.

A carrier frame may have a door which is arranged on a front side of the carrier frame and which is pivotally connected to the carrier frame and can be pivoted between an open position and a closed position, the drawers being retained by the door in the carrier frame when the door is in the closed position and can be inserted into the rack when the door is in the open position. In one embodiment of the invention, the door is arranged in the support frame in such a way that it cannot be detached from the support frame without being destroyed.

The support frame can be made of pure stainless steel, for example, with a surface coating being advantageous due to the high heat capacity of the stainless steel.

A surface coating of the carrier frame, of rigid or flexible components, can provide thermal insulation from the process chamber or from hot solvents in liquid or vapor form. provide. Furthermore, the surface coating can provide an anti-adhesive effect, so that the surface coating reduces condensation of the solvent on the coated components.

Cords can be stretched in an insert, or in other words in a plane, of the support frame. Hoses can be stretched particularly advantageously, for example PTFE hoses. The use of hoses is particularly advantageous because the hollow space, which can be filled with air, for example, means that the heat capacity of the hoses is lower.

The storage devices can be mounted horizontally in the base frame or can be moved so that components can be easily inserted and removed from different levels. The storage devices can be arranged vertically one above the other. Components can be placed on the storage devices, i.e. they can rest on the storage device on their underside, or they can be hung on hooks or other geometric elements. It should be understood that the present disclosure allows for any mounting or storage of the components by providing a modular, flexibly adaptable system. Various storage devices can be inserted into and removed from the base frame as needed to minimize the thermal capacity of the support frame in each process run of the process chamber. Cords or hoses can be made of an elastic material that has an elasticity such that the hoses deform under the weight of a component, e.g. by lengthening by at least 1%, 5% or 10% in length. In this way, pressure points on the components can be avoided.

Tubular spacers (eg, sleeves) can be threaded onto cords or hoses, so that components lying on the cords or hoses can be separated from one another. Components can rest at least partially or completely on the spacers.

The support frame can have a number of fastening arrangements, so that a number of inserts can be inserted into the support frame one above the other and/or next to one another. As a result, greater flexibility can be provided for a larger number of different components in a carrier frame. For example, different inserts can be used in the support frame, and an insert can be designed for a specific type of component.

For example, an insert can have rods bent in a serpentine shape on two opposite outer sides of the support frame or on a storage plane, onto which the support rods can be placed.

For example, grids, cords, or mesh fabrics or nets can run in an insert between two opposite outer sides of the support frame or the storage plane.

Some examples are based on the knowledge that the solvent can be shielded from the component by points of contact between components and the carrier frame. This means that less or no solvent can act on the surface of the component at a point of contact. Due to flexible materials on which a component rests, solvents can also act to a small extent below the points of contact.

An insert can be made of PTFE struts, which are optionally reinforced with carbon or glass fibers. An insert can be made of struts which have a cavity, in other words which have a tubular shape, in other words individual struts can be made of tubes.

In general, at least one flexible or rigid component, or a component of the base frame or a storage device, can comprise a cavity, i.e. be formed as a tubular component, or tube.

Belts that are used to store components can run or be stretched in an insert. A band can provide a larger contact surface than a cord. A band can be made of a flexible material, for example a fabric made of glass fibers and/or carbon fibers or another suitable plastic fiber. The fabric can be permeable to solvents. For example, the fabric may be a loose mesh fabric in which a plurality of openings or passages are formed.

A flexible band or tube can be reinforced with a rod or wire, if necessary, by passing it through a cavity in the flexible material. Such a reinforcing bar may be made from any of the materials described.

The bearing devices can each define an area through their outer edges, which essentially corresponds to a base area of the base frame.

The components can be placed loosely on the planes or inserts, or they can be fixed or held in a specific position by one or more flexible or rigid components.

A storage device, which is arranged uppermost in the framework, can have an upwardly curved semicircular shape. This allows the support frame to make better use of the space available in a round process chamber. A semicircular shape bent upwards has the advantage that condensed solvent runs down the side of the element. This minimizes the risk of solvent dripping onto components during the process.

In summary, a modular system is provided with rigid and flexible inserts that can be flexibly integrated into a basket-like base frame, resulting in improved component pick-up that is modular at the same time and loading with a variety of different types of components (size, shape, material... .) can be loaded for different variations of a smoothing process. Deformations and imprints on the components can be minimized and the amount of solvent condensate on the components can be efficiently controlled by a material selection of carrier materials and surface coating according to the invention.
