Description

[0001] The invention relates to a method for applying at least one identification number for at least one component to a body-in-white product and / or to an intermediate product. Furthermore, the invention relates to a manufacturing system and a component manufactured by such a manufacturing system.

[0002] In production facilities, especially in press shops, components, especially sheet metal components, are provided with serial numbers (also known as identification numbers, code markings, or serial codes) for serialization. These serial numbers are applied during the first step of production on a coiling line. These are primarily identification numbers or codes, usually consisting of letters and numbers, that are printed onto the coil or flat sheet metal plates. This makes every assembly, even semi-finished products, easily identifiable, for example, through coding using laser marking.

[0003] The positioning of these identification numbers on the coil or blanks must be selected in such a way that, after the blanks have been formed and the component has been manufactured, the respective code is always located in the same location or in the same area of ​​each component with repeatable accuracy. Furthermore, other essential boundary conditions must be considered that complicate positioning or position finding. This positioning is usually performed in a very time-consuming and cost-intensive iterative process during manufacturing or production.

[0004] The object of the invention is to create a method and a manufacturing system by which an efficient, sustainable or environmentally friendly and at least partially automated serialization of components is enabled in order to enable the most reliable and informative traceability of the components.

[0005] This object is achieved according to the invention by a method having the features of patent claim 1 and by means of a manufacturing system according to the invention according to patent claim 9 or a component according to patent claim 10. Advantageous embodiments of the invention are the subject of the dependent patent claims and the description.

[0006] One aspect of the invention relates to a method for applying at least one identification number (or a coding or a code) for at least one component to at least one body-in-white product and / or to at least one intermediate product for producing the at least one component in a manufacturing process using a manufacturing system. Furthermore, a method for positioning identification numbers is also possible, using the same method steps through which the positioning is carried out, but the application is not mandatory.

[0007] The manufacturing system comprises at least one, in particular central, electronic computing device for processing data and at least one application device for applying the identification number to the bodyshell product and / or to the intermediate product, wherein further characters and markings can also be applied.

[0008] The manufacturing process exemplified in the present invention, with the corresponding manufacturing process steps, is presented as follows. However, this is by no means binding and may vary depending on the manufacturing process and include fewer manufacturing process steps or a multitude of additional manufacturing process steps. - The term "body-in-white product" refers in particular to a sheet metal coil or semi-finished product which is manufactured and provided for the production of the components. - Various intermediate products can be manufactured from the bodyshell product, from which the components are later manufactured after a number of manufacturing process steps. - As an intermediate product, a cut coil can be provided which has been cut or separated along an elongated direction of extension into at least two coil parts. - The intermediate product can also be blanks or sheet metal blanks or a stack of blanks that have been cut out of the bodyshell product. - Drawn parts can be produced from the blanks by drawing these blanks into a trough-shaped configuration, for example, using a drawing press. - The drawn parts can be cut into blanks by cutting, punching or removing all unnecessary material from the drawn parts. - The components are then manufactured from the cut parts as final products, although further refinement of the manufacturing process may be necessary in between. - The component should therefore represent a finished product. In particular, the component can be, for example, a front flap produced by forming and trimming, or a front flap outer skin or front flap inner panel made from a blank of a circuit board.

[0009] This component requires a unique assignment option during and / or after the manufacturing process, which is where the identification number comes into play, with a predefined positioning (location for the identification number) and predefined dimensions (size of the identification number). The term "identification number" is used here for a standard variant; the term "identification" or "ID" could also be used. Thus, an identification number can simply be an ID, which, as previously discussed, can also be a machine-readable code, such as a QR code.

[0010] For serialization, the identification, which is referred to throughout this invention as an identification number, is to be applied to the respective body-in-white products and / or intermediate products (depending on the design of the manufacturing process). This allows various information and / or values, such as the dimensions or origin of the body-in-white products and / or intermediate products and / or other properties, such as material properties and / or process or manufacturing parameters, to be recorded, and the components to be uniquely assigned accordingly. The information specified in the identification number as a coding or code can be represented, in particular, alphanumerically or using other numbering or counting systems.

[0011] This makes it possible for the identification number to be provided by stringing values ​​together to form an array, the contents of which represent the respective information about the component. For example, such an identification number can be generated as an 11-digit alphanumeric array ("H125-646214-5"), where the combination of the eleven digits represents the respective information. Accordingly, it is also intended that the identification number is read by a detection system that knows an algorithm to decipher the identification number and thus read the information.

[0012] In addition, the identification number may also contain unencrypted information, which can be extracted directly from the identification number, i.e., without the application of an algorithm. A combination of coded and uncoded, or encrypted and unencrypted, information within the identification number is also possible.

[0013] In particular, the beginning (the first digit or digits) of the identification number must be detectable and readable, for example, to understand a sequence of identification numbers and to divide them into them (for example, all identification numbers begin with the semi-finished product supplier, so "H" is always the first digit, ...354H1256485617H 125364... →...354-H1256485617-H125364...). This identification number must therefore also be particularly visible and detectable, for example, by sensors (by a detection device or an optical detection device) and the human eye.

[0014] With regard to the identification number, it is also possible to provide the identification number with a unique identification or code, for example, which distinguishes the respective component from all others. It is also possible to provide each identification number with its own identification or code, which distinguishes this identification number from all other identification numbers. This is important, for example, if at least two identification numbers are to be applied to a component that would otherwise be indistinguishable from one another because they are on the same component. This means that before the identification number is created and applied, corresponding information can be provided. This information is later necessary, for example, for component traceability and the allocation of components to body-in-white products.

[0015] Furthermore, it is possible to initially provide only a specific first part of the identification number and, during the application of the identification number to the body-in-white and / or intermediate product, to create a further second part to complete the identification number before it is applied immediately afterwards. This would allow information that only becomes known immediately before application to be integrated into the identification number. For example, a timestamp or an assignment to the meter of the body-in-white product on which the identification number is immediately printed. It would also be possible to transmit the identification number incompletely to the application device and only complete it with an incremental code during application, thus enabling a clear distinction, for example, between the respective components.

[0016] Alternatively or additionally, information can also be subsequently assigned or linked to the applied identification number. For example, an identification number or serial code can be applied without any special logic and only subsequently assigned / linked to relevant information from a database of the manufacturing system or even an external database. The identification number does not directly disclose any information. Instead, a database is accessed via a link represented by the identification number to retrieve the relevant information or to store or save it in the database for this identification number.

[0017] In a particularly simple embodiment, the identification number could also be simply an incremental value, which is used only as a unique link to information from a database, for example, as a unique key or "primary key." In one example, it is known that a unique digit ("1m") is required for the identification number every 1 meter (e.g., based on the well-known Eurofer barcode). Thus, an incremental encoder is used to measure when the next meter-dependent digit for the identification numbers needs to be changed. A meter of tape X is then taken in real time from an exemplary production line, and during the manufacturing process, for example, a higher tape meter, such as 1365.5 meters ("1365m"), is used to generate the identification number.In other words, these meter-dependent digits for the identification numbers and thus also the identification numbers are provided incrementally.

[0018] Furthermore, in addition to the alphanumeric design, it is also possible to use binary codes, barcodes, QR codes, etc., for example, an endless band of codes, in particular machine-readable codes, as identification numbers, depending on the design of the invention. Furthermore, other identification devices (RFID tags) could also be glued or otherwise attached, which require a unique positioning, which in turn would be detectable by this invention. This means that the identification numbers do not necessarily have to contain numbers; they only need to enable a unique assignment.

[0019] As mentioned previously, the dimensions of the identification number must also be considered, which includes, for example, the length, size, shape, and other dimensional properties of the identification number itself. For example, if the identification number has a certain length, this can affect its positioning / placement on the component.

[0020] As previously mentioned, the positioning of the identification number must also be precisely determined to ensure the desired readability and legibility, but also to keep this identification number ideally untouched or undamaged, or at least legible, throughout the manufacturing process. If, for example, the identification number is incorrectly positioned, the identification number could be pulled along during the component drawing process, rendering it illegible and unrecognizable. Alternatively, it could be cut off during the cutting or punching process, which would not only render the number illegible but also incomplete. Furthermore, the unique assignment would be lost, which could have fatal consequences.

[0021] In addition to applying identification numbers, it is also possible to apply other symbols, shapes, classes of markings (drilling and cutting marks), reference symbols or reference markings, etc., using the application device and a virtual positioning on the component. All of these examples can be applied to the body-in-white product or coil using the application device on a production line. For example, circles, lines, and shapes for analyzing forming behavior can also be applied to the body-in-white products and / or intermediate products.

[0022] In particular, it is possible to use one application device, for example with multiple laser beams for application, or multiple application devices with respective laser beams that operate synchronously, depending on the design. Furthermore, respective application devices can also process a top and / or a bottom of the coil. This means that identification numbers and / or other markings can be applied to the top and / or bottom by means of the application device. It would also be possible to arrange printing devices on the application device by means of which the identification numbers can be printed. When printing identification numbers, there is also the advantageous option of providing different colors to differentiate between identification numbers. Furthermore, this differentiation can also be provided for the different tracks, so that each track has its own color (e.g. red / blue).This allows, for example, a plant operator or a person in the manufacturing process or later on, to immediately identify which component is being processed based on its color. These colors can thus detect traces or mark the top and / or bottom of the coil, or identify the unit from which the components originate. Different printing facilities can print different colors, or a printing facility can use different colors.

[0023] The invention is based on the idea of ​​affixing or applying the identification number to the body-in-white and / or intermediate product at the earliest possible point in the entire manufacturing process. This enables continuous assignment of the component throughout the entire manufacturing process, regardless of the manufacturing stage or manufacturing process step the component in question is in. To achieve this, it is necessary to determine an advantageous positioning that ensures that the identification number is not damaged, interrupted, or rendered illegible during the manufacturing process. For example, the identification number is applied to particularly flat and large areas of the component. Accordingly, a positioning must be found and determined that, ideally, remains untouched or unprocessed during the manufacturing process.For particularly small components, this can be a particularly challenging task, as the dimensions of the identification number play an even greater role than with an identification number where the dimensions are particularly small relative to the component. Therefore, the process now aims to simplify positioning so that the identification number is particularly easy to read and understand throughout the entire manufacturing process and thereafter.

[0024] It is also possible to encode the identification numbers using a different number system and thus change the length, for example a base 36 or base 62 number system. This means that the alphanumeric codes represent fewer values ​​and are therefore shorter. Base 36 is a number system which, in contrast to the decimal number system (base 10), consists of 36 different characters, including the digits 0 to 9 and the letters A to Z. By expanding to include letters, larger numbers can be represented with fewer digits or characters. Using a base 36 number system to encode identification numbers makes it possible to reduce the digit / number length because larger numbers or more information can be represented with fewer characters, which improves the summary when labeling components.Base 62, on the other hand, is structured similarly to base 36, but with a larger selection of characters. While base 36 has exactly 36 characters, base 62 has exactly 62 characters. These characters include the numbers 0-9, the uppercase letters AZ and the lowercase letters az. By expanding to include uppercase and lowercase letters of the alphabet as well as numbers, larger numbers can be represented with fewer characters than in base 36. This enables an even more compact representation of large numerical values ​​and contributes to a further reduction in the number length for the identification numbers. The resulting shorter length of the respective identification numbers also makes it possible to represent smaller, defined areas on the bodyshell product for the respective components. Furthermore, any other number systems or coding systems are equally possible. .

[0025] Thus, according to the invention, the following repetitive process steps are carried out: - Positioning the at least one identification number on the at least one corresponding component represented by a simulation of the manufacturing process. According to the invention, it is therefore provided that the positioning of the identification number on the component represented by a simulation of the manufacturing process is carried out in particular as a function of specifications for the positioning, in particular in an electronic computing device of the manufacturing system. This means that a simulation is first provided or already exists that can be applied for this method. For example, a finite element simulation, in particular a forming simulation, can be used that has already been used during a design and / or development process, in order to save resources and working time in particular.

[0026] For example, an area can be defined in which the identification numbers can be applied. This area is determined by specific parameters and specifications, which are stored, for example, in an electronic computing device of the manufacturing system. The identification numbers are positioned within this defined area, taking into account component-specific requirements and production conditions, and then subsequently applied. The dimensions of the area are designed in particular to ensure that the identification numbers and a specified tolerance fit within it. In other words, it is not the identification number that is positioned in the simulation, but a corresponding area, for example, a rectangular or elongated area.

[0027] The simulation therefore makes it possible to represent the component as a finished product and to analyze it in the simulation. For example, the component can be moved and adjusted in all degrees of freedom to view it from different angles. The simulation interface is user-friendly and offers functions such as zooming and navigation to enable detailed investigations of individual areas of the component. Furthermore, various analyses can be performed to examine properties such as strength and durability. These virtual possibilities allow the component to be examined accordingly.

[0028] In this example, this could be a representation of the pulled front flap, shown on a display device with a corresponding user interface (UI), which in turn is electronically coupled to the electronic computing device. The UI application thus shows a 3D representation of the component on which the identification number is to be placed. A preview allows the result to be checked in advance. Functions for saving and exporting are also available, for example, as are tools to provide support. This gives the user the opportunity to view the entire component in all degrees of freedom in order to decide in which area or directly at which location the identification number could be particularly advantageously positioned in order to make it particularly visible or detectable at the end of the manufacturing process.

[0029] Therefore, a positioning is selected that remains as unaffected as possible during the manufacturing process. In particular, an area that undergoes only minor changes, such as slight bends, deformations, or similar, can be selected. This makes it particularly easy to define the positioning of the identification number along the component in the simulation, allowing different areas to be tested. Furthermore, multiple identification numbers could be applied, or even additional information could be integrated.

[0030] Simulation is used to determine the positioning of the identification number. By analyzing the simulated component, it enables a retrospective determination of the positioning to the original form, for example a circuit board as the intermediate product or a coil as the body of the product. In the simulation, the circuit board is represented as a flat surface with a specified size and thickness. The calculation steps used for the simulation are then back-calculated to determine the original shape of the component or circuit board. This means that the virtual positioning of the identification number on the surface of the simulated component is traced back to the actual positioning on the circuit board. This process allows the exact position of the identification number on the circuit board to be determined, which is important information for the further manufacturing process. - Acquisition of initial position parameters for positioning on the component relative to a specific reference point. Accordingly, the acquisition of initial position parameters on the component is performed relative to the reference point (or zero point). After determining a well-positioned identification number, the user can now specify that this positioning is the desired one. The simulation verifies this positioning and acquires the corresponding position parameters, particularly the X, Y, and Z parameters, which are defined relative to a given reference point. These parameters are therefore also determined in such a way that the dimensions of the identification number and its contact with the component are defined. If, for example, the identification number is resting on an uneven surface, not only the length and width but also the curvature – concave, convex, or wavy – are recorded.All these position parameters are important for determining the precise positioning of the identification number and thus the corresponding position parameters. In particular, the identification number is considered as a surface that rests on another surface on the component. The reference point can be defined depending on the simulation; for example, it can be a central reference point of the entire component from which the entire design or simulation is based. The relationship between the identification number and the reference point thus provides the initial position parameters for further steps in the method according to the invention.

[0031] A reference point is usually defined by geometric features or specific coordinates. This can, for example, be a specific point on the surface of the component that is uniquely defined by its spatial coordinates. Alternatively, reference points can also be defined by geometric properties such as intersections of lines or surfaces, centers of circles, or other distinctive features. In a finite element simulation, reference points can also be nodes in the network of elements that model the component.

[0032] In other words, the identification number is defined relative to the reference point by specifying its position in relation to the coordinates or geometric properties of the reference point. This can be done by specifying offsets along the X, Y, and Z axes, which determine the exact position of the identification number on the component relative to the reference point. Additionally, other parameters such as angles or curvatures can be considered to determine the precise orientation of the identification number.

[0033] In addition to the X, Y, and Z axes or coordinates, angles such as alpha, beta, and gamma could also be taken into account to provide further degrees of freedom and thus enable additional positioning options in the simulations. These angles describe a rotation of the identification number relative to the component, providing further options for aligning the identification number. For example, angle alpha describes rotation around the X axis, beta describes rotation around the Y axis, and gamma describes rotation around the Z axis. By including these angles, more complex positioning and orientation of the identification numbers can be achieved. This is particularly important in cases where the component has irregular or curved surfaces, as the precise placement of the identification numbers could otherwise be difficult. - Carrying out a backward simulation, corresponding to the simulation, of the manufacturing process of the at least one component up to the at least one body-in-white product and / or up to the at least one intermediate product. Thus, it is provided that the backward simulation of the manufacturing process of the component up to the body-in-white product and / or up to the intermediate product is carried out. The backward simulation or forming simulation, as it is called in this invention, refers to the process in which the results of the already known simulation or forward simulation, which represents the finished product, are used to reconstruct the original shape or original form of the component or the circuit board. A key difference between backward and forward simulation is that in a forward simulation the input is given, whereas in a backward simulation the output is fixed.This process begins with the identification of a positioned identification number on the simulated component. The corresponding positional parameters, such as the X, Y, and Z coordinates, are then recorded relative to a defined reference point. Reverse simulation traces the identified positional parameters and other relevant data to reconstruct the original shape of the component or board, namely the in-white product and / or the intermediate product. This means that the virtual positioning of the identification number on the simulated component is reversed with respect to the actual positioning on the board. This process determines the dimensions and exact location of the identification number on the board.

[0034] The simulation already in use thus already enables the adjustment of the position parameters and the display of the identification number at the specified location / position. In other words, the component is to be processed backwards to restore or display the original state, namely the body-in-white and / or the intermediate product, and to provide or display the body-in-white and / or the intermediate product in the simulation. The 3D simulation, in particular, thus enables a step-by-step backward process through the backward simulation, which, depending on the specifications, can be carried out step by step or can lead directly from the component to the body-in-white and / or the intermediate product. - Detecting the second position parameters corresponding to the first position parameters on the at least one body-in-white product and / or on the at least one intermediate product after the backward simulation. Following this backward simulation, it is thus provided to detect the second position parameters corresponding to the first position parameters on the body-in-white product and / or on the intermediate product. This means that the already known position parameters of the identification number on the component are tracked using the backward simulation in order to determine which corresponding points or areas or second position parameters on the body-in-white product and / or on the intermediate product can be assigned to the later first position parameters on the component.In other words, this process step enables a precise assignment of the position parameters on the body-in-white product and / or on the intermediate product to the later position parameters on the finished component, whereby a precise placement of the identification number on the body-in-white product and / or on the intermediate product can be determined. - Determining the positioning of the identification number on the at least one body-in-white product and / or on the at least one intermediate product depending on the second positioning parameter. Accordingly, the respective positioning is now also determined according to the specifications.

[0035] In other words, the first position parameters on the component should be traced back relative to a predetermined reference point until the second position parameters of the body-in-white and / or intermediate product are reached. In particular, it is possible to represent not just one blank or intermediate product with an identification number for the component to be manufactured on the body-in-white and / or intermediate product and thus on the original mold. A body-in-white can also have intermediate products and thus a multitude of blanks or drawn parts, which in turn can contain a multitude of identification numbers. By positioning an identification number on a component, the positioning of the identification number is traced back by means of simulation analysis and thus by backward simulation.If multiple components are manufactured from a single body-in-white and / or intermediate product, especially identical components, the identification numbers are transferred to all components and traced. This allows multiple identification numbers for different components to be placed on the body-in-white and / or intermediate products.

[0036] The same applies when intermediate products are manufactured into further intermediate products. This means that the positioning of the identification numbers is tracked along the entire production chain through simulation analysis and reverse simulation. For example, if an intermediate product contains multiple subassemblies or parts, the identification numbers are transferred to all of these elements and traced. This allows the corresponding identification numbers or ranges for identification numbers for the parts or subassemblies it contains to be positioned on each intermediate product.

[0037] From a technical perspective, reverse simulation in this case is performed by analyzing the position parameters along the production chain of the manufacturing process. First, the position of the identification number on the drawn front flap is recorded. This position is then transferred to the intermediate product (e.g., individual blanks for drawing) by transferring the positioning of the identification number to the intermediate product. The identification number is then transferred to the next intermediate product (e.g., large blank / half coil). The position of the identification number relative to the first intermediate product is taken into account and adjusted accordingly. Finally, the position of the identification number is transferred to the body-in-white (coil). The positions of the identification numbers of all previous intermediate products are taken into account and transferred to the body-in-white accordingly.This process of reverse simulation makes it possible to determine the exact positioning of the identification number along the entire manufacturing chain and to ensure that each component or intermediate product can be uniquely identified.

[0038] At the end of the process, the body-in-white product, in this case the coil, is represented, for example, in a 2D CAD drawing. The position of all identification numbers is represented, particularly on a representative area of ​​a coil based on the results of the reverse simulation, or a repeating logic is defined for this purpose, or a repeating section of the entire coil is defined. The positions of the identification numbers are precisely specified in the 2D CAD drawing to ensure that they are consistently visible / capturable for the component manufacturing process. A representative area therefore refers to only a portion of the coil, since an entire coil would not be representable in its entirety due to potential lengths of several hundred meters.

[0039] Thus, the second position parameters are recorded as position data for positioning the identification numbers on the body-in-white and / or intermediate product. These second position parameters are specified relative to a defined reference point in the example CAD drawing. The defined reference point in the CAD drawing serves as a reference point from which the positions of the identification numbers are precisely determined. The second position parameters, such as the X, Y, and Z coordinates or other geometric properties, are specified relative to this reference point. Recording the second position parameters on the drawing ensures that the identification numbers can be applied at the appropriate locations on the body-in-white or intermediate product. - Transmission of the second position parameters from the electronic computing device to the application device of the production system, by means of which the identification number is applied to the at least one body-in-white product and / or to the at least one intermediate product depending on the second position parameters. Thus, finally, it is provided that the transmission of the second position parameters is carried out from the electronic computing device to the application device of the production system, by means of which the identification number is applied to the body-in-white product depending on the second position parameters. This means that the second position parameters have been recorded and determined, for example, after several iterations for the most advantageous positioning.Once determined, for example, by a user of the manufacturing system, the information about this positioning and thus the second position parameters can be transmitted to the application device manually, semi-automatically, or fully automatically, preferably electronically. This transmission can occur either via cable or wirelessly. This allows the design of the manufacturing system to vary. For example, the electronic computing device, acting as the central unit, can transmit the second position parameters to remote application devices in a production hall.

[0040] Using the second positioning parameters, the application device can now apply the correct identification numbers to the correct positions on the body-in-white and / or the intermediate product. This offers the advantage that the body-in-white and / or the intermediate product can be labeled by the manufacturing system, and that the identification numbers are already applied to the individual intermediate products or components after they have been cut. Thus, the identification number should be essentially continuously readable or detectable at every subsequent manufacturing process step up to the finished component, since the positioning was selected for this purpose, thus also providing the advantages of good readability.If, for example, an identification number is unreadable due to a static detection device or due to a movement sequence during a production step, additional identification numbers can be applied, for example, in different positions, rotated, enlarged / reduced, mirrored, or applied in some other way. In particular, this enables the traceability and assignment of each individual component already manufactured, regardless of the manufacturing process step of the unfinished component. In the finished state, the identification number is recognizable at the position specified in the simulation, which is particularly advantageous for both humans and machines.

[0041] The identification number therefore enables, for example, comprehensive documentation and management of manufacturing data, and the described method is particularly advantageous from a very early stage in the overall process. Furthermore, service and maintenance processes can be improved by enabling rapid identification of components that may require repair or replacement. This minimizes downtime and increases productivity. In summary, a particularly clear and legible identification number not only promotes quality in manufacturing but also leads to increased safety, traceability, and overall performance of the respective components.

[0042] In an advantageous embodiment of the invention, it is provided that the specifications for the positioning of the identification number are determined depending on material properties and / or geometric properties and / or manufacturing process steps and / or the dimensioning of the identification number and / or process specifications. Furthermore, a labeling type can also be defined. Accordingly, it is provided that the positioning of the identification number is determined according to the material properties, taking into account, in particular, the properties of the material used in the bodyshell product and / or the intermediate product as well as the surface finish to ensure that the identification number is applied permanently and legibly.However, it should also be noted that different materials react differently to manufacturing process steps, which means that these manufacturing steps must be closely monitored to account for, for example, the effects of cutting, drawing and other manufacturing process steps. It is also important how the material reacts to the application method when applying the identification number. This means that the application method, such as printing, on certain materials must be designed in such a way that the print is retained until the end of the manufacturing process. Furthermore, the dimensions of the identification number must be taken into account according to the material properties in order to provide a suitable, readable size. For certain application methods, such as embossing, the dimensions must not result in the embossing being compressed and thus becoming illegible.Thus, the positioning of the identification number also depends on the geometric properties. The shape and structure of the component are taken into account to ensure the identification number is applied in a suitable location that is easily accessible and clearly visible, yet not affected during the machining process. Furthermore, additional constraints can be considered when positioning the identification numbers. One example is the minimum distance between the identification number on the body-in-white and / or intermediate product or circuit boards, since a certain installation space is required for application using laser heads, for example.Additionally, a minimum distance to edges or deformations or deformation areas can also be considered to ensure that the identification numbers are not placed too close to these edges / areas, which could compromise the readability or integrity of the codes. Accordingly, the identification numbers are to be applied sufficiently far apart to avoid interference or damage during the application process. Furthermore, areas for subsequent process steps can be considered, such as the positions of suction cups for component transport or welding points. The identification numbers should be positioned in such a way that they do not impair or disrupt these areas, in order to ensure the smooth running of subsequent processes.In summary, the size and font of the identification number are determined according to the requirements or specifications in order to enable optimal readability and comprehensibility without compromising the functional or aesthetic properties of the component.

[0043] In an advantageous embodiment of the invention, it is provided that the backward simulation is applied as a post-processing step of the simulation. Backward simulation as post-processing refers to the fact that, after a simulation has been performed, the data or results of this simulation are used in a subsequent step to simulate backward step by step or to perform backward calculations step by step. In the context of simulations, this can mean that the results of a forward simulation, in which certain input parameters were used, are used to identify the origin or influencing factors of certain results, without having to create a new simulation or perform complex calculations.Specifically, this could mean that after a simulation has been performed, the results of that simulation are used to step backward through the model and identify the positional parameters that led to those specific results. In particular, this allows for the reapplication of a previously created simulation to save resources and time. Furthermore, this backward simulation can be implemented more easily, allowing the already known manufacturing process steps to be traced individually.

[0044] In another advantageous embodiment of the invention, it is provided that the identification number is also positioned on an unfinished component in a selected manufacturing process step. Thus, different manufacturing process steps can be represented individually in the backward simulation, whereby a manufacturing process step can be selected as an intermediate step to position the identification number. This makes it possible to enable positioning not only in the finished component, but also in other intermediate steps, in order to provide a comprehensive range of possible applications for the simulation. For example, the simulation can extend up to the finished painting process of the component, which would make it possible for a user to specify the identification number before this painting process, for example to also provide protection for the identification number during the painting process.In particular, this is intended to enable flexible design of the determination.

[0045] In another advantageous embodiment of the invention, it is provided that an automatic or manual adjustment of the positioning is carried out virtually. For this purpose, a display device with the user interface is provided, and software is configured to detect and implement the respective manual adjustments by the user via commands, cursors, or other means. Furthermore, it is also provided that these adjustments are carried out largely semi-automatically, but above all automatically, in order to simplify the process of determining the identification number. For example, dedicated software, optimization algorithms, or artificial intelligence can know and use the minimum specifications for the identification number as well as specified tolerances for dimensioning and curvature.Adjustments or optimizations in the positioning process can thus be performed either automatically or manually by experienced specialists. Potential improvement opportunities can also be identified and implemented accordingly to achieve improved positioning of the identification number. This adjustment can, for example, include fine-tuning the positioning depending on specific production specifications or taking additional constraints into account. This allows the system to automatically search for an area that meets these specifications.

[0046] In another advantageous embodiment of the invention, at least one favorable area for positioning the identification number on the component is suggested. An automatic search for an area for the identification number is carried out depending on the dimensions and tolerances across the entire area or surface of the component. All areas or areas that would be suitable for applying the identification number could thus be suggested. In particular, the simulation could be presented to a user on the display device in such a way that all suggested areas or areas are highlighted in one color to provide visual contrast and thus simplify positioning.For example, all suggested surfaces or areas could be displayed in green, allowing the user to search for and specify a position within the green area or area that meets their specifications or preferences. In particular, a simplified, ergonomic user interface should be provided to enable particularly easy positioning of the identification number on the component for later application to the body-in-white and / or intermediate product.

[0047] In another advantageous embodiment of the invention, at least one unfavorable area for positioning the identification number on the component is suggested. This allows the user to identify and avoid potentially unfavorable areas on the surface of the component in order to determine an advantageous placement of the identification number. By visually highlighting the unfavorable area in red, for example, the user is clearly signaled that this area is not suitable for positioning the identification number. This improves the accuracy of the positioning process, as the user can quickly identify potential problem areas.

[0048] In an advantageous embodiment of the invention, the identification number is applied to the bodyshell and / or the intermediate product by a printing process, an engraving process, or a laser device. Adhesive elements, stickers, or labels with the identification number can also be printed and affixed according to the positioning. Good legibility and ease of application are particularly important here. In particular, the application method and thus the application of the identification number must also be selected depending on the material properties and the dimensions of the identification number.

[0049] A further aspect of the invention relates to a manufacturing system for applying at least one identification number for at least one component to a body-in-white product and / or to an intermediate product in a manufacturing process. The manufacturing system is designed to determine respective identification numbers for all components and to determine respective virtual positions of these identification numbers on the body-in-white product and / or on the intermediate product in an electronic computing device. Depending on these positions, the identification numbers can be applied to the body-in-white product and / or to the intermediate product by means of an application device of a production system of the manufacturing system for producing the body-in-white product and / or the intermediate product. Furthermore, the components can be produced from the body-in-white product and / or on the intermediate product by means of a production system of the manufacturing system.It is intended that for these positionings, relative distances between adjacent identification numbers can be determined based on the geometric dimensions of the adjacent components, and that the identification numbers can be used as reference symbols for the respective manufacturing process steps of the respective components by means of a manufacturing facility for producing the components. This means that for these positionings, relative distances between adjacent identification numbers can be determined based on the geometric dimensions of the adjacent components. This means that component-specific parameters are calculated and defined taking into account the geometric differences between adjacent areas of the body-in-white product.

[0050] In other words, the manufacturing system comprises, for example, a central electronic computing device, the application device in the production plant for the body-in-white products and / or intermediate products, possibly with its own electronic computing device, and a manufacturing plant for producing the components.

[0051] For example, the identification numbers are applied in the production facility at a semi-finished product supplier, while the intermediate products (e.g., cutting blanks on coil lines) and the components (on press lines) are produced by a manufacturer. Thus, the manufacturing system encompasses the entire process from the steel manufacturer or semi-finished product supplier to component production at the in-house manufacturer.

[0052] In addition, the manufacturing system can, for example, have at least one data acquisition system with a data acquisition device or optical data acquisition device for capturing the identification numbers, as well as one or more databases for providing data that is both linked by an identification number and applicable for uploading and downloading parameters for the positioning of identification numbers on body-in-white products and / or intermediate products. It is also possible for the manufacturing process to be used exclusively for traceability from the finished component to the body-in-white product, and no further data is captured. Thus, in this case, no additional data acquisition system would be required. Furthermore, the data acquisition system can also be carried out by a human, for example, the plant operator who manually references.

[0053] It is also possible for the manufacturing process to be used exclusively for traceability from the finished component to the body-in-white product, with no further data being recorded. Thus, no additional data recording system would be required. Furthermore, the data recording system can also be operated by a human, for example, by a plant operator who manually references.

[0054] The manufacturing system is designed to determine respective identification numbers for all components, even partially in the central electronic computing device, and to later expand these with the application device. Furthermore, the respective virtual positions on the body-in-white and / or the intermediate product are determined in an electronic computing device. Alternatively, the determination / positioning can also be done manually, in particular the specification of the relative distances. These positions can then be transmitted to the application device or to the system's own electronic computing device, for example, via the database or an intermediary ("man in between").

[0055] Depending on these positionings, the identification numbers are applied using the application device of the production plant to manufacture or complete the body-in-white product and / or the intermediate product. The production plant continuously produces the body-in-white product or a coil, to which the identification numbers are subsequently or during production using the application device, each time according to the positioning of the future components.

[0056] The production plant also comprises a detection system with a detection device, for example an optical detection device or an increment encoder for the correct positioning of the identification numbers, wherein, for example, a laser system and / or inkjet printer applies the identification numbers to the coil with the aid of the detection device.

[0057] For these positionings, relative distances between adjacent identification numbers can be determined based on the geometric dimensions of the adjacent components. This means that component-specific parameters are calculated and / or defined taking into account the geometric differences between adjacent areas of the body-in-white product.

[0058] The identification numbers can then be used as reference symbols for the respective manufacturing process steps of the intermediate products and / or components that are also manufactured using the manufacturing plant. This means that the body-in-white product or the body-in-white product provided with the identification numbers is transferred to the manufacturing plant, e.g. a press shop, from which the intermediate products and / or components are then manufactured. The identification numbers serve as reference points / reference symbols for calibrations, referencing, or other process steps during the manufacture of the components. The manufacturing plant also includes a recording system with a recording device or optical recording device for recording the identification numbers and for calibrating or referencing the tools or the production plant. Alternatively, orIn addition, reference symbols may also be applied, which can also be used for referencing or calibration.

[0059] Further designs and integration of additional components are also possible.

[0060] The manufacturing system is designed to determine a unique identification or an identification number for the at least one component and to virtually string these identifications or these identification numbers together to form a sequence of identifications or identification numbers, maintaining a predetermined relative distance between consecutive identifications or identification numbers. The manufacturing system is then designed to apply this virtual sequence as an actual track of identification numbers to the at least one body-in-white product and / or to the at least one intermediate product by means of an application device of the manufacturing system. This means that a virtual creation of the sequence is first provided, followed by an actual application of the track.

[0061] The manufacturing system comprises an electronic computing device for providing identification numbers or other identifications, for virtually positioning identification numbers on virtual components and for detecting position parameters / information by means of which an actual application of the identification numbers is possible.

[0062] For this application, the production system comprises the application device, which manually, semi-automatically, or fully automatically records and processes all the information required for the precise application of identification numbers. In particular, it is possible for the electronic computing device and the application device to be coupled to one another, or for the electronic computing device to be integrated into the application device. Furthermore, respective application devices can also process a top side and / or a bottom side of the coil. This means that identification numbers and / or other markings can be applied to the top side and / or bottom side using the application device. When printing identification numbers using a corresponding printing device of the application device, there is also the advantageous option of using different colors to distinguish one identification number from another.

[0063] Furthermore, the manufacturing system also comprises production systems for coils, which are designed to carry out the manufacturing process steps depending on the identification number and / or depending on reference symbols or references or the identification numbers as reference symbols.

[0064] The production system for producing a coil or for applying the identification numbers to the coil, on which the identification numbers or identifications and, if applicable, reference symbols are to be applied or printed in a predetermined arrangement, thus comprises at least the application device and preferably a corresponding electronic computing device for controlling the application device. This electronic computing device arranged on the production system can also be configured to perform possible virtual representations, adjustments, and / or simulations in order to display and adjust the respective identification numbers on the virtual components.Alternatively, for example, a simpler design of an electronic computing device can be arranged, which is designed only to process position information or similar data and transmit it to the application device or thereby control it. Accordingly, in addition to the production system, the manufacturing system would have to include at least one additional, preferably central, electronic computing device that performs these virtual tasks and has the appropriate processor, power, hardware, and software resources for this purpose.

[0065] The relationship between this powerful electronic computing device and the production facility within the manufacturing system may be designed in such a way that a physical and / or spatial separation of the two components is intended.

[0066] The production facility, which is located at the supplier's site, for example, handles the direct production of the coils. This production facility is designed to apply the identification numbers and, if applicable, reference marks to the coils according to the customer's specifications. Various application methods can be used to transfer or apply the desired information to the coils.

[0067] The other (central) electronic processing unit, however, is located at the customer's site. Its main task is to generate, manage, and, if necessary, adapt the identification numbers and / or the position data of the identification numbers and / or the position data and / or relative distances for the identification numbers and / or areas. This electronic processing unit enables flexible handling of the identification and positioning data and can also be used, for example, for inventory management or product traceability. Communication between the processing unit and the production facility takes place via a data transmission connection (wireless / internet) or manually via an intermediary, enabling the transmission of the information required for coil labeling.

[0068] This division of tasks between supplier and customer enables a clear structuring of the manufacturing process. The supplier concentrates on the physical production of the coils, while the customer retains control over the identification numbers and their relative position data and, if applicable, reference symbols. They can adapt these according to the relevant specifications and transmit them to the supplier for application of the identification numbers. On the other hand, the customer can also transmit information about the structure and / or logic and / or composition of the identification numbers, but the identification numbers are only fully created by the supplier. For example, the first digit is "H" and is specified by the customer for the manufacturer (H = manufacturer XY); the remaining information / code components are then generated by the manufacturer itself, in particular according to a predefined logic.

[0069] Furthermore, the manufacturing system also includes, for example, a recording device, which is arranged, for example, on the production line. This device serves to record the identification number and / or the reference symbols applicable to the manufacturing process steps.

[0070] The identification number can also be read from the body-in-white product and / or intermediate product and / or finished component and / or coil by the internal electronic computing device or by another electronic computing device, for example, the production plant in combination with the recording device, such as an optical recording device. In addition, the information contained in the identification number and / or linked to this identification number can be verified by extracting it from a database or by storing further information about this identification number in the database or linking it to it.

[0071] The positioning of the identification number on the component is based on positioning specifications, which are stored, for example, in the external electronic computing device or supplied to it. First position parameters on the component relative to a reference point can thus be virtually captured in order to capture second position parameters on the body-in-white and / or intermediate product corresponding to the first position parameters on the component, for example, by means of a feasible backward simulation of the component's manufacturing process up to the body-in-white product and / or intermediate product. The positioning of the identification number on the body-in-white and / or intermediate product is determined depending on the second position parameters.In other words, a backward simulation of the components is preferably carried out in order to determine the respective position parameters of the identification numbers and their relative distances to each other on the body-in-white product.

[0072] The second positioning parameters can then be transmitted to the application device (or to the internal electronic computing device) of the manufacturing system in order to apply the identification number to the body-in-white product and / or the intermediate product. This transmission can be automated directly via the electronic computing device or can be derived by a specialist as a "man-in-between", an external entity, or from a database. The manufacturing system also includes, for example, a display device (for example on the production system or on the electronic computing device or on the application device) with a corresponding user interface and software to virtually display the results of the simulation and the positioning process of the identification number, as well as to enable it, in particular manually, by a user.In addition, the manufacturing system also includes, for example, communication modules for data transmission for wired and / or wireless communications and / or for remote data transmission between all components.

[0073] The production system may further comprise a holding device configured to hold the body shell products and / or intermediate products relative to a reference point during the application process. The application device may either comprise the holding device or be coupled to it to enable holding and application relative to the same reference point.

[0074] This holding device is thus used to enable the precise positioning or placement of the identification numbers and / or reference marks on the body-in-white products or intermediate products. The alignment provided by the holding device allows the application device to work efficiently and apply the identification numbers exactly where they are needed. In particular, it is possible to apply the identification numbers or codes, for example, in the production facility, such as a rolling mill or coil line, while the strip is moving. This is made possible by the continuous movement of the body-in-white product or coil as it moves through the production facility.

[0075] In a production facility, such as a rolling mill or coiling line, the application device can be configured to precisely and quickly apply the identification numbers or codes to the surface of the moving coils or raw product. The application device can be synchronized with the movement of the coil to ensure that the markings are placed precisely in the desired positions. In other words, the movement and positioning of the coil during the application of the identification numbers or codes is enabled by the holding device. This holding device is therefore designed to stably guide the coil as it moves through the manufacturing or production line.

[0076] Other possible features of the manufacturing system include data storage, input and output devices, and warning devices for warning signals to an environment or to a user in the event of a possible emergency.

[0077] Finally, the manufacturing system comprises a manufacturing plant designed to produce components as end products from the body-in-white and / or intermediate product. The production of these components takes place in particular depending on the applied identification numbers and / or reference symbols. This means that the manufacturing plant is now designed to produce the intermediate products and / or components step by step, wherein in particular the identification numbers and / or reference symbols are used as a reference point for manufacturing process steps such as blank production and / or cutting and / or drawing. These reference symbols are applied along the elongated extent of the body-in-white during production of the body-in-white and can be used by the manufacturing plant to carry out precise steps in the production of the intermediate products and / or components as the end products.In particular, referencing is particularly important during blank production and during blank cutting from the coil. Referencing is already applied in subsequent process steps, for example, a blank outline and / or blank geometry. These can also be used as such referencing here.

[0078] However, the reference marks are not the only marks or reference points by which the manufacturing facility can orient itself. It is also possible to use the identification numbers or their dimensions or imprint on the application surface and the points contained therein as reference points. This eliminates the need for constant recalibration of the body-in-white product. Instead, only the recording of the reference marks or identification numbers and the calibration and / or referencing of the tool and / or manufacturing process step relative to them are required.

[0079] The use of reference marks on the body shell or coil enables calibration and / or referencing of the manufacturing process steps, such as cutting the blanks or sheets from the coil into intermediate products and / or components. By detecting the reference marks using a detection device, in particular an optical detection device in the manufacturing system, very precise positioning information can be recorded, which is used for calibrating and / or referencing or aligning the machines. These reference marks serve as reference points for various manufacturing process steps to ensure that the material is processed or processed precisely. The use of reference marks also allows deviations in positioning to be detected and corrected.Furthermore, the identification number can be used as a reference mark, which can be used to calculate all other positions of all other identification numbers. After the identification number has been applied, all further processing steps, such as cutting or machining, are carried out according to the determined positions. From a technical perspective, the identification number is thus used as a central component or marker, enabling information capture and, through its precise positioning, enabling the precise processing of the body-in-white product down to the final components.

[0080] The manufacturing system therefore preferably works as follows: A component is represented virtually in the external electronic computing device. The positioning of the identification number for this component is determined. Subsequently, the positioning of the next identification number for the next component on a virtual body-in-white is determined, taking into account at least individual manufacturing process steps, thereby determining the initial position and the distances between the identification numbers of adjacent components on this body-in-white or coil.

[0081] This information is transmitted to the production facility for manufacturing the coil or body-in-white. The first identification number is then applied to the body-in-white / coil using the application device and the holding device, according to the previously determined position. With the distances now known for positioning the second identification number, this can also be positioned. This can be repeated along the length of the coil / body-in-white while the coil is being manufactured. Reference symbols or other markings can also be applied.

[0082] It is also possible for several tracks of identification numbers to be applied one after the other on the body-in-white product and / or on the intermediate product, for example by means of the electronic computing device. In this case, it is provided that in addition to the one track, another track, or even a plurality of tracks, is / are applied to the body-in-white product and / or on the intermediate product. In particular, the application method and thus the application of the track is possible in multiple ways. A plurality of tracks can be applied, for example, one above the other or relative to a specific reference point. Through this flexible arrangement or through such flexible application, different information can be displayed on the body-in-white product and / or intermediate product without impairing readability.For example, multiple identification numbers or other markings can be applied at different levels or positions, or on different tracks, to enable additional details. In particular, multiple components from different production tracks can be created from a single body-in-white and / or an intermediate product, with at least one track of identification numbers being applied to each production track. This allows components to be assigned to their specific production tracks. Accordingly, at least one track with identification numbers should be applied to each production track. For this, defined areas would have to be established in which the corresponding identification numbers can be applied.

[0083] The identification numbers applied do not need to be known from the outset, but can be redefined during the coil / body-in-white manufacturing process. Finally, the finished body-in-white is transferred to the manufacturing facility with identification numbers and / or reference marks. The facility uses the identification numbers and reference marks to enable the calibration and / or referencing of all necessary tools and / or process parameters.

[0084] The final result is a trimmed drawn part as a component and thus as a finished product, which has an identification number. This number was already applied to the body-in-white and remained untouched, legible, or machine-readable throughout the entire manufacturing process, making it easy to capture, for example, by an optical scanning device. This identification number can already contain all the information or serve as a link to a database in which further information about the corresponding component is stored or can be added later in the component's life cycle.

[0085] In summary, a manufacturing system is proposed that processes the body-in-white products through to the finished component as the final product. This enables particularly resource-saving, efficient, and trustworthy traceability of the components and all process steps through the applied identification numbers. The components / final products themselves can actually only be further intermediate products that are then joined with other components in a later process step, for example, welded to form a finished body.

[0086] A further aspect of the invention relates to a component produced by a method according to the first aspect and / or produced by means of a production system according to the second aspect, with or without all possible embodiments mentioned.

[0087] Further features of the invention emerge from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures, can be used not only in the respective specified combination, but also in other combinations or on their own.

[0088] The invention will now be explained in more detail using a preferred embodiment and with reference to the drawings. They show: Fig. 1 is a pictorial diagram illustrating a manufacturing system for applying at least one identification number to at least one component during a manufacturing process; Fig. 2 a schematic plan view of a first component in a simulation, on which an identification number is to be applied; Fig. 3 a schematic plan view of a second component in a further simulation, on which a further identification number is to be applied; Fig. 4 a schematic plan view of a circuit board with the components; and Fig. 5 a technical drawing of a body-in-white product on which the respective identification numbers for the components are applied.

[0089] In the figures, identical and functionally identical elements are provided with the same reference numerals.

[0090] The Fig. 1, Fig. 2, Fig. The examples shown in Figure 3 are intended to represent only embodiments and are by no means to be applied exclusively in this form or carried out in this chronological sequence of process steps.

[0091] Fig. 1 shows an image diagram illustrating a manufacturing system 1 for applying at least one identification number ID to at least one component 10 in a manufacturing process with a plurality of manufacturing process steps. The manufacturing system 1 comprises at least one central electronic computing device 2, an application device 3 in a production facility 6, and a manufacturing facility 8 for producing the components 10.

[0092] The production facility 8 comprises various production devices 8a, 8b, 8c, through which the raw product 12 is first cut into blanks 13 by the first production device 8a. The blanks 13 are then drawn into drawn parts 13a, 13b by the second production device 8b. There is, in particular, a spatial and temporal separation between the process steps or production devices 8a and 8b. For example, the blank stacks are stored for several months before they are further processed into components 10. The drawn parts 13a, 13b are then cut into blanks 14 by the third production device 8c, which either already represent the components 10 or can be further refined into the components 10.

[0093] The manufacturing system 1 is designed to determine the respective identification numbers (ID) and their positions for all components 10 and to make them available to the application device 3. This information can then be transmitted to the application device 3, for example, electronically, automatically, or through an intermediary ("man in between").

[0094] Depending on these positions, the identification numbers ID are applied using the application device 3 of the production plant 6. The production plant 6 continuously produces a body-in-white product 12 or a coil, onto which the identification numbers ID are subsequently applied "on a continuous basis" using the application device 3.

[0095] The labeled, finished body-in-white product 12 is transferred or delivered from the production facility 6 to a manufacturing facility 8, wherein the production facility 6 and the manufacturing facility 8 may be spatially separated from one another, for example, even operated by different companies. This facility guides the body-in-white product 12 or coil through several manufacturing process steps, which may also be spatially and temporally separated or decoupled from one another, to the components 10 as the final products. The identification numbers ID remain untouched or at least legible and / or machine-readable and are visible. They also serve, for example, as reference symbols for the respective manufacturing process steps of the components 10. This means that the body-in-white product 12 provided with the identification numbers ID is transferred to the manufacturing facility 8, for example, a press shop, from which the components 10 are then manufactured.The identification numbers ID can thus be used as reference points for calibrations and / or referencing or other process steps during the manufacture of the components 10.

[0096] Furthermore, it is also possible that relative distances between adjacent identification numbers ID can be determined for the positioning as a function of geometric sizes of the adjacent components 10.

[0097] In addition, it is possible to apply virtually positioned reference symbols such as lines, markings or other geometric symbols to the bodyshell product 12 and / or to the intermediate product by means of the application device 3.

[0098] It is also possible to use the identification numbers ID by means of the manufacturing facility 8 as the reference symbols for respective manufacturing process steps of the respective components 10.

[0099] For example, a reverse simulation implemented by the electronic computing device 2 for the respective components 10 could be used for the virtual positioning.

[0100] In order to provide particularly advantageous intercommunication of the main components, the electronic computing device 2, the production plant 6 and the manufacturing plant 8 have, for example, wireless communication, which is developed, for example, via the Internet or via other telecommunication networks.

[0101] In this case, it would be advantageous if a data storage device were provided from which data, in particular about the bodyshell products 12, intermediate products and / or components 10, can be acquired and / or in which data can be stored by means of the electronic computing device 2 and / or by means of the production plant 6 and / or by means of the manufacturing plant 8. This means that data as well as data about the components 10 and data that can be linked to the respective identification numbers ID are made available in the data storage device, whereby in particular the manufacturing plant 8 and the production plant 6 can extract data and from which data can be acquired via the electronic computing device 2. For example, a user can enter data into the electronic computing device 2; the data is transmitted to the data storage device and made available to the manufacturing plant 8 and the production plant 6.For example, such a data storage could be designed as a cloud with a corresponding backend.

[0102] The production facility 6 and / or the manufacturing facility 8 can each comprise a detection system for detecting the identification numbers ID. Such a detection system of the production facility 6 comprises at least one detection device, for example an optical detection device, by means of which the identification numbers ID can be detected, as well as the body-in-white product in order to apply the identification numbers ID thereto. Such a detection system of the manufacturing facility 8 comprises at least one detection device, for example an optical detection device, by means of which the identification numbers ID and / or reference symbols can be detected, as well as the body-in-white product in order to orient or adapt respective tools, manufacturing parameters and / or holding devices and / or other components relative to the identification number ID or relative to reference symbols.

[0103] Furthermore, it is possible to virtually define defined areas in which the identification numbers (ID) can be applied. These areas have dimensions in terms of width, length, and height, in which the identification number can be completely applied, particularly with a certain tolerance. The defined areas can also be used by the production system 8 as reference symbols for the respective manufacturing process steps of the respective components 10.

[0104] The application device 3 can be configured to apply an endless band of identification numbers ID (a sequence of identification numbers ID) such that at least one identification number ID can be applied to one of the regions. Thus, it is provided to determine such a region for each component 10 and to pull the endless band through at the same height using the application device 3, with at least one identification number falling entirely within the region.

[0105] Fig. Fig. 2 shows a plan view of a first component 10a to illustrate a method according to the invention for applying a corresponding identification number ID1 for the component 10a on a Fig. 2 not shown intermediate product for the production of respective components 10a and 10b, whereby the second component 10b is only in the Fig. 3. A body shell product 12 for the production of the intermediate products, also not shown, is shown later in Fig. 5. Furthermore, in the Fig. 2 to 4, such a body-in-white product 12 is provided as the starting point for the production of these components 10a, 10b. These components 10a, 10b are manufactured in particular in a manufacturing process by means of a corresponding manufacturing system 1. It is provided that the positioning of the corresponding identification numbers ID1 and ID2 (in Fig. 3) for components 10a and 10b (in Fig. 3) in a simulation of the manufacturing process and depending on the specifications for positioning, whereby in particular an electronic computing device 2 of the manufacturing system 1 can be used for this purpose.

[0106] The Fig. The simulation of the first component 10a shown in Figure 2 is thus shown as a top view. The identification number ID1 associated with the component 10a is intended to be positioned in such a way that it is particularly easy to read and understand. This is achieved by a user or a specialist placing the identification number ID relative to a reference point 0 on a surface or area of ​​the component 10a, in particular on its surface, in the simulation. This enables the first component 10a to remain continuously recognizable and traceable during the assembly processes.

[0107] To make this possible, the first position parameters x1, y1, z1 of the component 10a are first recorded relative to the reference point 0. These position parameters x1, y1, z1 define the distances or other features of the component 10a to the reference point 0, in particular in a simulation (e.g., FEM simulation), in order to define the ranges for this identification number ID1.

[0108] The identification numbers generally include a specific dimensioning, which is defined by length, width and, if applicable, depth in the shell product 12 (not in Fig. 2) and must be applied to the surface of the corresponding components 10a. Therefore, the position parameters x1, y1, z1 are first recorded to be used as starting points later in the process.

[0109] The method provides for and executes a backward simulation of the manufacturing process of component 10a down to the body-in-white product 12 and / or intermediate product. The shapes of component 10a represented in the simulation are not only used to represent and position the identification number ID1, but the entire manufacturing process chain is performed in reverse order. The simulation is thus analyzed to determine specific points so that the positioning of the identification number ID1 can also be identified on the original shape or on the body-in-white product 12 and / or intermediate product.

[0110] The goal is to use the first position parameters x1, y1, z1 to determine the Fig. 5 corresponding second position parameters x1*, y1*, z1* of the component 10a on the body-in-white product 12 and / or intermediate product after the reverse simulation. Since the body-in-white product 12 and / or intermediate product can be assumed to be a planar surface, e.g., a coil, the position parameter z1* could approach 0 (also applies to z2* from Fig. 3) and are therefore eliminated. Thus, the selected area in which the identification number ID1 must be applied is no longer on the component 10a (or component 10b in Fig. 3), but rather on the bodyshell product 12 and / or intermediate product or the corresponding selected area is localized.

[0111] By determining the positioning of the identification number ID1 on the bodyshell product 12 and / or intermediate product and thus the detection of the second position parameters x1*, y1*, z1*, it is provided that the application device 3 (not shown but Fig. 1 known) of the manufacturing system 1 with these second position parameters x1*, y1*, z1*, not shown, applies the identification number ID1 accordingly to the bodyshell product 12 and / or intermediate product.

[0112] In other words, the second position parameters x1*, y1*, z1*, which were determined by the backward simulation, are to be forwarded to the application device 3 in order to apply the identification number ID1 to the body-in-white product 12 and / or intermediate product. The application can be carried out, for example, by laser technology or printing processes, wherein the application device 3 comprises corresponding components that enable this process. The application device 3 is arranged or installed in particular where the coil is or was already clamped. No additional time should be required for application or labeling, since the coil is already clamped. The application should not involve any additional clamping of the coil and should not require any special process step.

[0113] For example, an identification number ID1 of 5 mm by 14 mm is positioned on a surface of the first component 10a and then determined by the backward simulation of second position parameters x1*, y1*, z1*, whereby various specifications, such as material properties or geometric properties or process specifications, can be taken into account.

[0114] Ultimately, this method is intended to enable particularly simple and ergonomic positioning of the identification number ID1 on the component 10a, whereby the corresponding positioning of the identification number ID1 on the body-in-white 12 and / or intermediate product is transferred via the reverse simulation. This avoids inaccuracies in the positioning directly on the body-in-white 12 and / or intermediate product, so that the application of the identification number ID1 could, for example, be carried out directly by a manufacturer. Subsequently, the body-in-white 12 and / or intermediate product is cut, and the respective cut parts are processed, with the identification number ID1 of the component 10a remaining particularly or ideally continuously untouched, so that it is particularly easy to read or understand later.

[0115] Furthermore, it is possible for favorable areas 16 and unfavorable areas 18 to be automatically suggested for positioning the identification number ID1 on the component 10a. This is based on an automatic analysis of the dimensions and tolerances over the entire area or surface of the respective components 10a (also 10b). Favorable areas 16 suitable for applying the identification number ID1 could be marked in a display device visible to the user by a visual change, e.g., color highlighting in green, for example, to enable easy and precise positioning. At the same time, unfavorable areas 18, which are less suitable for positioning the identification number ID1, could be highlighted in a contrasting color, e.g., red, to provide the user with a visual warning and avoid selecting problematic positions.

[0116] Fig. 3 shows a further plan view of the additional second component 10b, which is analogous to Fig. 2, was manufactured using the same process to apply the identification number ID2 for this second component 10b to the bodyshell product 12 and / or intermediate product, which is also not shown here. Furthermore, a manufacturing system 1 and an electronic computing device 2 for the simulation are also shown.

[0117] A special feature of this second component 10b in this example shown here is that both the first component 10a and this second component 10b both originate from the same body-in-white product 12 and / or intermediate product. Therefore, the respective identification numbers ID1 and ID2 are to be applied to the body-in-white product 12 for both components 10a and 10b. For this purpose, it is also provided that the identification number ID2 of the second component 10b is positioned in a defined favorable area 16. An unfavorable area 18 is also displayed. For this purpose, corresponding further first position parameters x2, y2, z2 are also recorded here and converted into corresponding further second position parameters x2*, y2*, z2* (in Fig. 5) on the body-in-white product 12 and / or intermediate product by the backward simulation.

[0118] In order to determine the positioning of the second identification number ID2 on the body-in-white product 12 and / or intermediate product depending on these second position parameters x2*, y2*, z2*, it is provided that the second component 10b is arranged, for example, directly next to or in an immediate area next to the first component 10a on a blank of the body-in-white product 12 and / or intermediate product. In a specific example, the body-in-white product 12 could be designed as a coil having a board nesting, wherein each board 13 (not in Fig. 2 and Fig. 3) is cut to size so that both components 10a, 10b can be removed from this circuit board 13. Thus, the shell product 12 contains at least one circuit board 13, which is later processed into the components 10a, 10b, in particular through steps such as cutting and drawing in the manufacturing process. Any other circuit board / component combinations are also possible for the circuit board nesting; the examples shown in the figures are not to be understood as exclusive.

[0119] However, in order to apply the identification numbers ID1, ID2 of the respective components 10a, 10b to the body-in-white product 12 and / or intermediate products right from the start, it is provided that the corresponding position parameters x1, y1, z1 and x2, y2, z2 of the respective identification numbers ID1, ID2 on the respective components 10a, 10b are calculated back to the corresponding second position parameters x1*, y1*, z1* and x2*, y2*, z2* through the backward simulation. This allows the identification numbers ID1, ID2 to be applied precisely and relative to the reference point 0 on the body-in-white product 12.

[0120] In this way, it is possible to apply a plurality of identification numbers ID, ID1, ID2 to the body shell product 12 and / or intermediate product, from which a plurality of components 10a, 10b can later be manufactured. In particular, it is provided that the specifications for the positioning of the identification numbers ID (not in the Fig. 2 and Fig. 3), ID1, ID2 are defined depending on the material properties, geometric properties, manufacturing process steps and the respective dimensioning of the identification numbers ID, ID1, ID2.

[0121] Fig. 4 shows a plan view of a board 13, from which the drawn parts 13a and 13b are drawn or manufactured for the production of the components 10a and 10b and are subsequently manufactured to form the components 10a, 10b (see Fig. 2 and Fig. 3). It is intended that the blank 13 is provided as a part of the body-in-white product 12 and / or intermediate product (not shown), which means that such a part is already pre-cut. It is thus intended that at least one blank as the blank 13 for further drawn parts 13a, 13b is defined and cut out of the body-in-white product 12 and / or intermediate product. This is particularly shown in Fig. 5. The corresponding position parameters x1, y1, z1 and x2, y2, z2 of the respective identification numbers ID1, ID2 on the respective components 10a, 10b are also shown.

[0122] The goal is therefore to manufacture the specific components 10a and 10b from these blanks 13 and drawn parts 13a, 13b. The identification numbers ID1 and ID2 for components 10a and 10b are intended to be applied directly to the drawn parts 13a, 13b, even better to the blank 13, but above all directly to the body shell 12 and / or intermediate product, in order to enable the traceability of the corresponding components 10a and 10b.

[0123] It is particularly advantageous if all identification numbers ID1, ID2 can be inserted in each manufacturing process step, so that the identification numbers ID1 and ID2 are not only used in the finished simulation of the components 10a and 10b as in Fig. 2 and Fig. 3, but also in an intermediate step, as here in Fig. 4, which offers an additional positioning option. This is also relative to a given and in Fig. 4 but not shown reference point 0 and is used to define the second positioning in an earlier manufacturing process step or to calculate it back using the backward simulation.

[0124] Furthermore, it is also possible to apply multiple identification numbers ID1, ID2 to a body-in-white product 12 and / or intermediate product, even though only one component 10a, 10b is removed or manufactured from it. Thus, a component 10a or 10b is assigned a plurality of identification numbers ID1 or ID2, which are found in various areas during the manufacturing process. For example, with so-called circuit boards 13 as intermediate products that are susceptible to twisting, for example rectangular circuit boards, it can happen that these pass the code detection stations or cameras or an optical detection device rotated by 180° during the process. For this reason, it is advantageous to apply two identification numbers ID1 or ID2 in order to ensure that one of them is always located in the field of view or in the detection range of the code detection station or the optical detection device.

[0125] Finally, the backward simulation is also applied, for example, as post-processing of the simulation, whereby the existing simulation of the components 10a, 10b is utilized. The manufacturing process steps are arranged backward in order to carry out the positioning of the identification numbers ID1, ID2 up to the body-in-white product 12 and / or intermediate product as simply and resource-efficiently as possible. Through such a backward simulation, the identification numbers ID1, ID2 can also be positioned on an unfinished component 10a, 10b in a selected manufacturing process step, so that not only the final manufacturing process steps can be used to position the identification numbers ID1, ID2, but also other manufacturing process steps.

[0126] Fig. 5 shows a top view of a planar surface that can be represented as a CAD drawing and shows the overall representation of the body-in-white product 12 or a representative extract of the body-in-white product 12 (the body-in-white product 12 or a coil can, for example, be up to 4500 m long), including the blanks 13, from which the respective drawn parts 13a, 13b (not shown) for a plurality of components 10a and 10b are later removed.

[0127] Furthermore, a manufacturing system 1 and an electronic computing device 2 for the simulation are also shown.

[0128] The aim of this procedure is to define the identification numbers ID1, ID2 on the simulation of the components 10a and 10b, so that after the backward simulation on the Fig. 5. It is intended that the positioning with the position parameters x1*, y1*, z1* and x2*, y2*, z2* in relation to the Fig. 5, the reference point 0 (also not shown) is calculated and the positioning is displayed or shown accordingly so that the relevant data can be transmitted to the application device 3 (not shown). Fig. 5 also a different reference point 0 than the one in the Fig.2 and / or 3. These known reference points 0 can then be converted to the new reference point 0, a process that can be carried out, for example, by the application device. This makes it possible to apply the identification numbers ID1, ID2 to the planar surface of the body-in-white product 12 and make them available for the entire manufacturing process. Thus, it is possible to apply a plurality of identification numbers ID1, ID2 to a plurality of circuit boards 13, which enables the traceability of a larger number of components 10a, 10b through their respective identification number ID1, ID2. Thus, the body-in-white product 12 and / or intermediate product is provided with the identification numbers ID1, ID2 in the correct places or positions or positionings, which ensures the constant availability of the identification numbers ID1, ID2 for later treatments and processing in the manufacturing process.

[0129] In other words, a possibility is proposed for carrying out the forming of sheet metal components. This forming is an extremely complex process that cannot simply be controlled by geometric assignments or functions such as component unfolding. This is because a large part of the deformations, such as stresses and strains, result directly from the material itself during deep drawing. Therefore, the determination and optimization of the positioning of the identification number ID1, ID2 on the completely formed components 10a, 10b takes place, rather than through iterative, i.e. complex, adjustment as in the current state of the art. In the state of the art, for example, a "trial & error" approach is also used, which is therefore possible with the automated procedure proposed here.

[0130] In summary, the invention proposes an efficient positioning or position finding of serial codes or identification numbers ID1, ID2 for individual parts or components 10a, 10b on semi-finished products or body-in-white products 12 and / or intermediate products or blanks 13, drawn parts 13a, 13b and cut parts.
