Description

Technical Field

[0001] The present invention relates to a method and a mobile terminal for identifying the material of an additive manufacturing component. The present invention also relates to an additive manufacturing component and a production method thereof. Background Art

[0002] Using additive manufacturing to supply replacement or wear parts to customers on-site has the potential to significantly reduce facility downtime and storage costs. For example, when a part is needed, the customer can additively manufacture the corresponding replacement or wear parts for the facility directly on-site.

[0003] However, supplying spare parts or wear parts to a customer site using additive manufacturing also carries certain risks. For example, when inserting a material filament reel into an additive manufacturing device, a customer may mix up the material filament reel and use an incorrect material filament reel, e.g. one with an incorrect material. This may result in the additive manufacturing device itself not working, since different filaments may require different temperatures etc. in order to be fully printable. On the other hand, it may happen that a customer installs an apparently suitable component or spare part into a machine after additive manufacturing, but that the component cannot withstand the corresponding effects in the machine because it is made of the wrong material.

[0004] In order to prevent an additive manufacturing device from producing components from incorrect materials, DE 10 2022 107 007 A1, for example, discloses a method for operating an additive manufacturing device.

[0005] DE 10 2010 007 566 A1 describes an anti-counterfeiting system with a security element for unique marking of all types of products. The security element comprises a covert or overt security feature to distinguish pirated copies or imitations of a product from the original. The security feature consists of at least one inorganic luminescent pigment.

[0006] For further prior art, see DE 10 2016 125 471 A1, DE 10 2017 118 601 A1 and WO 2021 / 176097 A1.

[0007] The invention is based on the object of creating an improved technology for testing and ensuring the desired component quality of additively manufactured components, preferably for container handling systems. Summary of the invention

[0008] This object is achieved by the features of the independent claim. Advantageous developments are specified in the dependent claims and in the description.

[0009] One aspect of the present disclosure relates to a method for identifying a material of a component, preferably a container processing device. The method comprises providing a component manufactured (e.g. completely) by means of an additive manufacturing device. The method further comprises irradiating the component with electromagnetic radiation by means of a radiation source. The method further comprises recording a spectrum, preferably an emission spectrum and / or an absorption spectrum, of the irradiated component by means of a recording device (e.g. comprising a camera, a spectrometer and / or a hyperspectral camera). The method further comprises evaluating, by means of an evaluation device, a (e.g. complete, partial or predominant) match of the recorded spectrum with at least one predetermined spectrum (spectral characteristic) associated with a predetermined material, the predetermined material having at least one nanoparticle marker (a marker made of nanoparticles) for (e.g. uniquely) identifying the predetermined material. The method further comprises outputting the evaluation result by means of an output device (e.g. a visual, auditory and / or tactile output device).

[0010] Advantageously, the method makes it possible to detect whether the additively manufactured component is actually additively manufactured from the desired material. For this purpose, nanoparticles are used as markers, with which the material can be clearly and reliably identified by spectral analysis. This can advantageously ensure that the correct material is used for the additively manufactured component, which can have a positive effect on component, product and / or production reliability (e.g. storage, correct component in a machine, etc.). Advantageously, the nanoparticles used as markers do not change the properties of the (base material of) the predetermined material. The method also allows batch tracking and unique identification of materials marked with at least one nanoparticle marker for individual identification.

[0011] Preferably, UV radiation, VIS radiation or infrared radiation can be used as electromagnetic radiation.

[0012] Preferably, any radiation source for emitting electromagnetic radiation in the ultraviolet, visible or infrared range can be used as the radiation source. The radiation source can be, for example, an LED, a laser, a gas discharge lamp, a halogen lamp or an incandescent lamp.

[0013] Preferably, when evaluating the match with the spectrum of at least one predetermined material, it can be checked in particular whether at least one nanoparticle marker can be identified in the recorded spectrum (preferably emission spectrum and / or absorption spectrum). This can be identified in the recorded spectrum by means of selective absorption and / or emission peaks, bands, signal attenuation or signal absence, intensity maxima or intensity minima, or other characteristic signal shapes of at least one nanoparticle marker.

[0014] Preferably, nanoparticle labels (labels made of nanoparticles) may have a nanoparticle size between 1 nm and 100 nm.

[0015] Preferably, the nanoparticle mark can be selected from any optical and spectrally identifiable material. These materials can be chemically and physically stable in the base material of the predetermined material, and have little or no adverse effect on material properties. The very suitable material that can be used as the nanoparticle mark is organic dye and / or complex compound, organic luminescent agent and / or inorganic luminescent agent. These luminescent agents have been widely used in the identification of objects, for example, in the case of banknotes and other valuable documents. Organic dye and / or complex compound and / or luminescent agent can be selected from organic conjugated systems, such as fluorescein derivatives, coumarin derivatives, oxazine derivatives, rhodamine derivatives, luminophores, pyrromethene dye derivatives etc. For the use of complex compounds, rare earth complexes complexed with Eu3+, Tb3+, Sm2+, Sm3+, Nd3+, Ce3+, Pr3+, Pr4+, Dy3+, Ho3+, Er3+, Tm3+, Yb2+ or Yb3+ are used, and complex compounds complexed with Ru3+, Cr3+, Mn2+, Mn3+, Mn4+, Fe3+, Fe4+, Fe5+, Co3+, Co4+, Ni2+ or Cu+ and organic conjugated ligands such as acetylacetone (ACAC), dibenzoylmethane (DBM), 4,4,4-trifluoro-1-(2-naphthyl)-1,3-butanedione (TFNB), thenoyltrifluoroacetone (TTFA), bipyridine derivatives, phenanthroline derivatives or other organic complexing ligands are also used. The inorganic luminescent agent can be a selected solid compound containing one or more luminescent ions selected from the following: In+, Sn2+, Pb2+, Sb3+, Bi3+, Ce3+, Ce4+, Pr3+, Nd3+, Sm2+, Sm3+, Eu2+, Eu3+, Gd3+, Tb3+, Dy3+, Ho3+, Er3+, Tm2+, Tm3+, Yb2+, Yb3+, Ti3+, V2+, V3+, V4+, Cr3+, Mn2+, Mn3+, Mn4+, Fe3+, Fe4+, Fe5+, Co3+, Co4+, Ni2+, Cu+, Ru2+, Ru3+, Pd2+, Ag+, Ir3+, Pt2+ and Au+. Preferred inorganic luminescent pigments are binary, ternary or quaternary halides, oxides, oxyhalides, sulfides, oxysulfides, sulfates, oxysulfates, selenides, nitrides, oxynitrides, nitrates, oxynitrates, phosphides, phosphates, carbonates, silicates, oxysilicates, vanadates, molybdates, tungstates, germanates or oxygermanates of the elements Li, Na, K, Rb, Mg, Ca, Sr, Sc, Y, La, Ti, Zr, Hf, Nb, Ta, Zn, Gd, Lu, Al, Ga and In.

[0016] Particularly preferably, the predetermined material is a plastic material having at least one nanoparticle marker, preferably PA CF, PA, TPU, PLA or Tough PLA.

[0017] In an exemplary embodiment, the radiation source, the recording device and the output device and optionally the evaluation device are integrated in a mobile (portable) terminal, preferably in a handheld terminal. The method can thus advantageously be implemented particularly ergonomically and, for example, directly on the machine where the component is installed or to be installed or at any other desired location.

[0018] In another exemplary embodiment, the method further comprises retrieving additional information associated with the predetermined material from a data storage device (e.g., an evaluation device, a mobile terminal, or a server device) when a match with a predetermined spectrum associated with the predetermined material is determined during the evaluation. The method may further comprise outputting the retrieved additional information by means of an output device. Preferably, the additional information may comprise at least one of the following: material number, material name, batch number, material production time, digital reference (link) to an electronic file (e.g., a document), a data sheet, an instruction manual, and a material composition. Advantageously, this means that in addition to merely identifying the material, other information about the component and / or material may be output to the user, whereby the use of the component and optionally the user's knowledge may be further improved.

[0019] In one embodiment, the method further comprises at least one of the following:

[0020] - enabling operation of the machine (e.g. installing or to be installed a component in the machine) if a match is determined during the evaluation to be with a predetermined spectrum associated with a predetermined material that is desired for the machine and has at least one nanoparticle signature, and / or

[0021] - sending the evaluation result to a server device, preferably a cloud server device; and / or

[0022] - adjusting the operation of the machine based on the evaluation results (e.g. installing or to be installed the component in the machine).

[0023] Advantageously, this allows other actions to be performed beyond simply identifying the material, such as preventing damage to the machine or objects processed by the machine due to incorrect component materials.

[0024] In another embodiment, the component is formed entirely of a plurality of adjacent additively manufactured (e.g., plastic) material layers (e.g., PA CF, PA, TPU, PLA, or Tough PLA material layers), and all of the material layers include one or more different nanoparticle markers. Alternatively or in addition, providing the component includes:

[0025] - mixing base material particles, preferably plastic particles (e.g. PA CF, PA, TPU, PLA or Tough PLA particles) with one nanoparticle marker or a plurality of different nanoparticle markers to form a mixture;

[0026] - extruding the mixture to form filaments; and

[0027] -Production of components from filaments using an additive manufacturing device.

[0028] This has the advantage that the component can be inspected from either side, even when it is worn or damaged, so that the method can also be used, for example, to analyze why a machine, a product (eg a container) or a component has become defective.

[0029] Another aspect of the present disclosure relates to a system configured to implement the method for identifying as disclosed herein.

[0030] Another aspect of the present disclosure relates to a mobile terminal, preferably a handheld terminal, for identifying the material of an additively manufactured component. The mobile terminal comprises a radiation source for irradiating the component with electromagnetic radiation. The mobile terminal comprises a recording device (e.g., comprising a camera, a spectrometer and / or a hyperspectral camera) for recording a spectrum of the irradiated component, preferably an emission spectrum and / or an absorption spectrum. The mobile terminal comprises an output device (e.g., visual, auditory and / or tactile) for outputting information to a user. The mobile terminal comprises an evaluation device configured to evaluate a match (e.g. complete, partial or predominant) of the spectrum of the component irradiated by the radiation source recorded by the recording device with at least one predetermined spectrum associated with a predetermined material having at least one nanoparticle marking (marking made of nanoparticles) for (e.g. uniquely) identifying the predetermined material, and / or for the purpose of evaluating a match with at least one predetermined spectrum (spectral characteristic) associated with a predetermined material having at least one nanoparticle marking for (uniquely) identifying the predetermined material, by means of a (e.g. wireless) communication interface (e.g. radio, WLAN, Bluetooth, NFC and / or infrared communication interface), sending the recorded spectrum to a server device, and optionally receiving an evaluation result from the server device by means of the communication interface. The evaluation device is also configured to operate an output device to output the evaluation result. Advantageously, the same advantages can be achieved with the mobile terminal already described herein with reference to the method.

[0031] In an exemplary embodiment, the evaluation device is further configured to operate a (e.g. wireless) communication interface (e.g. radio, WLAN, Bluetooth, NFC and / or infrared communication interface) of the evaluation device to send the evaluation results to the machine and / or server device.

[0032] In another exemplary embodiment, the evaluation device is further configured to operate an output device to output additional information associated with the predetermined material if a match with a predetermined spectrum associated with the predetermined material is determined during the evaluation, wherein the additional information preferably includes at least one of the following: material number, material name, batch number, material production time, a digital reference (link) to an electronic file (e.g., a document), a data sheet, operating instructions, and material composition.

[0033] In one embodiment, at least one of the following is met:

[0034] - when outputting results, if a mismatch is determined during evaluation, information about the lack of a match is output;

[0035] - When outputting results, if a match was determined during the evaluation, information about the existing match is output;

[0036] - When outputting the results, if a match with a predetermined spectrum associated with the predetermined material is determined during the evaluation, information about the predetermined material is output.

[0037] Advantageously, a user can thus easily be informed whether the component he is testing is actually additively manufactured with the material desired for the intended use.

[0038] In another embodiment, the total volume and / or weight proportion of at least one nanoparticle marker in the predetermined material is ≥0.5% and / or ≤3% (e.g. ≥0.6% and / or ≤1%). It is particularly advantageous that this does not substantially cause any changes in the material properties, but still enables safe and reliable detection of the nanoparticle marker.

[0039] In one embodiment variant, at least one nanoparticle label is a luminescent organic and / or inorganic and / or organometallic dye, pigment and / or complex compound.

[0040] In another embodiment variant, a plurality of spectra are predetermined, the plurality of spectra being associated with different predetermined materials, each predetermined material having at least one nanoparticle marker for (e.g. uniquely) identifying the respective predetermined material (e.g. a plastic material, preferably PACF, PA, TPU, PLA or Tough PLA), and a match with one of the plurality of predetermined spectra is evaluated. Advantageously, the method / terminal can thus be applied to different components made of different materials in order to determine in each case whether the respective component is made of the material desired for the intended use.

[0041] Preferably, a plurality of predetermined spectra can be stored on a data storage device (e.g. an evaluation device, a mobile terminal and / or a server device) and / or received via a (e.g. wireless) communication interface (e.g. a radio, WLAN, Bluetooth, NFC and / or an infrared communication interface) (e.g. of a mobile terminal).

[0042] In an exemplary embodiment, different predetermined materials used to (e.g., uniquely) identify the respective predetermined materials differ in at least one of the following:

[0043] - The same nanoparticle labeling in different weight and / or volume ratios;

[0044] - Different nanoparticle labeling;

[0045] - in each case of a plurality of different nanoparticle labels, a mixture of different nanoparticle labels; and

[0046] - In each case of a plurality of different nanoparticle labels, different weight and / or volume proportions.

[0047] Advantageously, a unique code may be provided by the respective at least one nanoparticle marking of the respective predetermined material for unique identification of the predetermined material.

[0048] Another aspect of the present disclosure relates to a method for producing a component for a container handling device. The method includes mixing base material particles, preferably plastic particles (e.g., PA CF, PA, TPU, PLA or Tough PLA particles) with a nanoparticle marker (a marker made of nanoparticles) or a plurality of different nanoparticle markers (markers made of nanoparticles) to form a mixture. The method also includes extruding the mixture to form a filament. The method also includes producing (e.g., the entire) component from the filament by means of an additive manufacturing device. Advantageously, the method can achieve the same advantages as those described herein with reference to the method for identifying a material.

[0049] In an exemplary embodiment, the component is formed entirely from multiple adjacent additively manufactured (e.g., plastic) material layers (e.g., PACF, PA, TPU, PLA, or Tough PLA material layers), and all of the material layers include one or more different nanoparticle markers.

[0050] In another exemplary embodiment, the component is a wear part, a spare part, a chain, a sprocket or a gear. Alternatively or in addition, the total volume and / or weight proportion of the at least one nanoparticle marker in the component is ≥0.5% and / or ≤3% (e.g. ≥0.6% and / or ≤1%). Alternatively or in addition, the at least one nanoparticle marker is a luminescent organic and / or inorganic and / or organometallic dye, pigment and / or complex compound.

[0051] Another aspect of the present disclosure relates to a container processing device having the component and / or the mobile terminal.

[0052] Preferably, the container handling device can be designed for temperature controlling, producing, cleaning, coating, testing, filling, closing, pasteurizing, labeling, printing, marking, laser marking and / or packaging containers for liquid or pasty media, preferably beverages, liquid foods or products from the pharmaceutical industry or the healthcare industry.

[0053] For example, the container may be realized as a bottle, a jar, a cartridge, a carton, a vial, a tube, or the like.

[0054] Preferably, the term "evaluation device" may refer to an electronic system (e.g., which is designed as a drive circuit or has a microprocessor and a data memory), which, depending on the design, can perform control tasks and / or regulation tasks and / or processing tasks. Although the term "control" is used herein, this may also include or be understood as "regulation" or "feedback control" and / or "processing".

[0055] The preferred embodiments and features of the present invention described above may be combined with one another as desired. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] Further details and advantages of the present invention are described below with reference to the accompanying drawings. In the accompanying drawings:

[0057] Figure 1 A schematic diagram of a method for testing a component according to an exemplary embodiment of the present disclosure is shown. DETAILED DESCRIPTION

[0058] Figure 1 The method for testing a component 10 is shown only schematically. The method is preferably used in a container processing plant.

[0059] Preferably, the component 10 is a wear part or a spare part. Particularly preferably, the component 10 is a sprocket, such as Figure 1 As shown, or a gear or a chain (eg a drive chain or a conveyor chain). Preferably, the component 10 can / is to be used in a container processing plant, for example in a machine 26 of a container processing plant.

[0060] The component 10 is produced by means of an additive manufacturing device 12 , such as a 3D printer.

[0061] The component 10 is irradiated with electromagnetic radiation by means of a radiation source 14. The radiation source 14 may be integrated into a mobile terminal 16, for example.

[0062] The spectrum of the irradiated component 10 is recorded by means of a recording device 18. This spectrum can be, for example, an emission spectrum and / or an absorption spectrum of the irradiated component 10. Preferably, the recording device 18 can also be integrated in the mobile terminal 16.

[0063] The recorded spectra are evaluated by means of an evaluation device 20. The evaluation device 20 can preferably also be integrated in the mobile terminal 16. However, the recorded spectra can also be transmitted by means of a communication interface 24 of the mobile terminal 16 to a server device 28 with its own evaluation device for evaluation (e.g. via a local area network or a global network, such as the Internet).

[0064] During the evaluation, the recorded spectrum is checked for a match with a predetermined spectrum. The predetermined spectrum is associated with or identifies a predetermined material having at least one nanoparticle marker. The predetermined spectrum can thus clearly identify the predetermined material. The predetermined spectrum can, for example, be stored in a data memory of the evaluation device 20 or can be received, for example, from a server device 28 by means of the communication interface 24 of the mobile terminal 16. The predetermined spectrum or its characteristic properties can, for example, be predetermined in a test of a predetermined material having at least one nanoparticle marker.

[0065] Preferably, the communication interface 24 may be a wireless communication interface, for example, a radio, WLAN, Bluetooth, NFC and / or infrared communication interface 24 .

[0066] This evaluation can be used to check whether the component 10 was actually produced from the desired (correct) predetermined material by means of the additive manufacturing device 12. The component 10 can be produced as required, for example, as described below.

[0067] First, base material particles may be mixed with one or more nanoparticle markers to form a mixture.

[0068] The base material particles are preferably plastic particles, for example PA CF particles (carbon fiber reinforced polyamide particles), PA particles (polyamide particles), TPU particles (thermoplastic polyurethane particles) or PLA particles (polylactide particles), for example Tough PLA particles.

[0069] The at least one nanoparticle label may preferably be a luminescent organic and / or inorganic and / or organometallic dye, pigment and / or complex compound.

[0070] The mixture with the base material particles and at least one nanoparticle marker can then be extruded by an extruder to form a (3D printer) filament. The filament can be extruded from the nozzle of the extruder at a predetermined pressure and temperature. The filament can be wound on a spool for the additive manufacturing device 12, for example.

[0071] The component 10 can then be additively manufactured from the filaments by means of the additive manufacturing device 12. Preferably, the component 10 can be made entirely from the filaments. For example, the component 10 can be completely formed from a plurality of adjacent additive manufacturing material layers, and all material layers can include at least one nanoparticle marker.

[0072] Preferably, the total volume and / or weight proportion of the at least one nanoparticle marker in the component 10 or filament is ≥ 0.5% and / or ≤ 3%.

[0073] In the following, reference is again made to the evaluation of the match between the recorded spectrum and the predetermined spectrum. According to the evaluation, the evaluation result can be output after the evaluation by means of the output device 22. The output device 22 preferably has a visual display and / or a loudspeaker. Preferably, the output device 22 can also be integrated in the mobile terminal 16.

[0074] Depending on the result of the evaluation, different information can be output by means of the output device 22 .

[0075] For example, if a mismatch is determined during the evaluation, information about the lack of match can be output, preferably visual information and / or acoustic information. The visual information can be output, for example, in the form of a colored, preferably red, symbol, for example in the shape of a cross. Alternatively or in addition, an acoustic warning tone can be output. The user then knows that, for example, the component 10 is made of the wrong material and is therefore unsuitable or only insufficiently suitable for the intended use.

[0076] Alternatively, if a match is determined during the evaluation, for example, information about the existing match can be output, preferably visual information and / or acoustic information. Visual information can be output, for example, in the form of a colored, preferably green symbol, for example in the form of a check mark. Alternatively or in addition, for example, an acoustic confirmation tone can be output. The user then knows, for example, that the component 10 is made of the correct / desired material and is therefore suitable for the intended use.

[0077] For example, if a match with a predetermined spectrum associated with the predetermined material is determined during the evaluation, information about the predetermined material may also be output.

[0078] For example, if a match with a predetermined spectrum associated with the predetermined material is determined during the evaluation, additional information associated with the predetermined material may also be retrieved from the data storage. Preferably, the additional information may include at least one of the following: material number, material name, batch number, material production time, digital reference (link) to an electronic file (e.g., document), data sheet, instruction manual, and material composition. The additional information may, for example, be stored in a database. Finally, the retrieved additional information may be outputted by means of the output device 22, preferably visually and / or audibly.

[0079] It is also possible to enable operation of the machine 26 in which the component 10 is installed or to be installed only if a match with a predetermined spectrum associated with a predetermined material is determined during the evaluation, the predetermined material being desired by the machine 26 and having at least one nanoparticle signature. For example, the evaluation device 20 may communicate with a machine controller of the machine 26 in order to enable the machine 26.

[0080] It is also possible to adjust the operation of the machine 26 based on the evaluation results. For example, the machine 26 can only be operated at its full power or speed if a match with a predetermined spectrum associated with a predetermined material that is desired by the machine 26 and has at least one nanoparticle signature is determined during the evaluation.

[0081] The machine 26 is particularly preferably a container conveyor or container handling machine, for example for tempering, producing, cleaning, coating, testing, filling, sealing, pasteurizing, labeling, printing, marking, laser marking and / or packaging containers.

[0082] It is also possible to send the evaluation result to a server device 28 , preferably a cloud server device. For example, the server device 28 may be a server device of the manufacturer of the machine 26 .

[0083] An example is explained above, in which during the evaluation the recorded spectrum is checked for a match with only one predetermined spectrum. However, it is also possible to predetermine a plurality of spectra. The plurality of spectra are associated with different predetermined materials, each predetermined material having at least one nanoparticle marker. In this way, a match with one of the plurality of predetermined spectra can be evaluated. In other words, it can be evaluated whether there is a match with one of the predetermined spectra, and if so, with which of the predetermined spectra a match exists.

[0084] Different predetermined materials can be clearly identified or distinguished from each other by, for example, different weight and / or volume proportions of the same nanoparticle marker, different nanoparticle markers, mixtures of different nanoparticle markers (in each case of multiple different nanoparticle markers) and / or different weight and / or volume proportions (in each case of multiple different nanoparticle markers).

[0085] The present invention is not limited to the preferred exemplary embodiments described above. On the contrary, there may be a variety of variants and modifications, which also utilize the inventive concept and therefore fall within the scope of protection. In particular, the present invention also claims protection for the subject matter and features of the dependent claims, regardless of the claims to which they refer. In particular, the individual features of independent claim 1 are each disclosed independently of one another. In addition, the features of the dependent claims are also disclosed independently of all the features of independent claim 1. All ranges specified herein are to be understood as being disclosed in such a way that all values ​​falling within the respective ranges are disclosed individually, for example also as respective preferred narrower outer limits of the respective ranges.
