The present invention relates to a method for documenting anomalies of an industrially manufactured product, in particular in the course of performing a quality check, a product being provided and checked by a user for anomalies, in particular for defects in and / or on the product. The invention is characterized in that a digital three-dimensional data model of the product is provided and at least partially displayed to the user on a two-dimensional display area, the user an anomaly found in the product via an input device on the digital three-dimensional data model of the product which is at least partially displayed on the display area detected in such a way that when the anomaly is detected, these spatial coordinates are assigned and at least one further parameter is assigned, the spatial coordinates and the at least one further parameter of the detected anomaly forming a data record, and the data record being transmitted to a data memory and stored. The present invention also relates to a system for documenting anomalies in an industrially manufactured product, in particular in the course of performing a quality check.

Description

The present invention relates to a method for documenting anomalies in an industrially manufactured product according to the preamble of claim 1 and a system for documenting anomalies in an industrially manufactured product according to claim 14.

As part of quality checks, products are primarily checked for compliance with certain technical documents, in particular by means of specifications, drawings, checklists, with regard to specified quality features. Every visible type of error should be recorded in order to identify the main areas of error and to derive long-term quality trends.

The defects found on a product usually do not affect the entire product, but are often limited locally to a small area at a specific location on the product and can therefore be localized very easily. The defects on a product are therefore location-specific, since their location on the product can be precisely determined and assigned to a point or at least a narrowly restricted area.

For recording errors in the context of a quality inspection for a product 1 like this in 1 is shown, it is known side views 2 , 3 , 4th of the product to be tested 1 into a grid sheet 5 to be transferred and on the grid sheet 5 to document. An exemplary grid sheet 5 with the side views 2 , 3 , 4th of the in 1 represented product 1 is in 2 shown. The grid sheet 5 is a flat two-dimensional coordinate system, the axes of which are labeled with numbers or letters for the unambiguous determination of individual coordinates. The different side views 2 , 3 , 4th of the product 1 are across the entire grid sheet 5 distributed so that specific points or areas on the side views 2 , 3 , 4th can be clearly assigned to certain grid coordinates. The size of the grid and thus the number of subdivisions on the two axes of the grid sheet 5 depends on the desired level of detail. The finer the grid, the more precise individual errors can be on the page views 2 , 3 , 4th of the product are recorded. The user who carried out the quality inspection on the product to be examined 1 now, if an error is detected, this can be done in the grid sheet 5 on the corresponding side view 2 , 3 , 4th document.

However, this has the disadvantage that the errors recorded are only ever shown in one of the page views 2 , 3 , 4th of the product 1 projected representation can be recorded and thus information on the actual location of the defect, especially if it is inside the product 1 lies or spans multiple page views 2 , 3 , 4th extends, cannot be recorded correctly or at least not completely. Furthermore, any errors found can also be displayed on several side views 2 , 3 , 4th of the product 1 projected, so that a single detected defect in the product 1 is distributed over several, non-contiguous grid coordinates and a later assignment of the individual grid coordinates to the one error is often difficult. The individual defects in the product can also be 1 can only be recorded with the accuracy of the grid coordinates. In addition, it is up to the user's imagination if a defect is found in the product 1 correctly on the side views 2 , 3 , 4th of the product 1 on the grid sheet 5 project and capture accordingly. This gives rise to the problem that the individual defects in the product to be examined 1 not clearly of a specific location on the product 1 can be assigned and, in particular, the evaluation is made more difficult, since an error can be distributed over several views and thus assigned to several, non-related grid coordinates.

In addition, the individual errors in a product can be identified by different users on the grid sheet 5 different grid coordinates are assigned, since the assignment of non-superficial errors to the individual grid coordinates depends on the spatial imagination of the respective user. There can also be errors in the product 1 which is not clearly a side view 2 , 3 , 4th of the product 1 can only be recorded on a side view2, 3, 4 by the user, so that further information about the defects in the product 1 get lost.

From the DE 10 2017 107 224 A1 a method for displaying component documentation is known, planning, manufacturing, model and maintenance data being provided from a digital data memory, from which a display of the component is generated and displayed in data glasses. In this case, data from component documentation that have already been recorded are provided and displayed on a display surface, in this case data glasses. However, nothing can be inferred from this document about the component documentation itself, in particular the type of documentation and the recording of defects in a product.

The present invention is therefore based on the object of specifying a method and a system for documenting anomalies in an industrially manufactured product with which the aforementioned disadvantages are avoided.

The present invention is further based on the object of specifying a method and a system for documenting anomalies in an industrially manufactured product which enables anomalies to be recorded in a location-specific manner.

The present invention is also based on the object of specifying a method and a system for documenting anomalies in an industrially manufactured product which enables the recorded data to be evaluated quickly.

These and other objects are achieved by a method for documenting anomalies of an industrially manufactured product according to claim 1 and by a system for documenting anomalies of an industrially manufactured product according to claim 14. Advantageous embodiments of the method can be found in claims 2 to 13 Advantageous refinements of the system can be found in claims 15 to 20.

An anomaly is, in particular, a deviation from an optimal standard or ideal product. This can involve faulty locations, damage, abnormalities, additional deposits and / or objects, for example sensors, on the product and the like. in particular, it can be a matter of a defect in and / or in the product. All of these deviations represent different types of anomalies. There can also be a fixed limit value above which a deviation from a standard product is an anomaly. Furthermore, there can be a second limit value from which an anomaly by a user should even be detected. The limit value can depend on the type of anomaly or on your location. For example, the limit value of a certain anomaly on a structurally relevant element of the product, for example on a connecting element or load-bearing element of the product, can be significantly lower than for the same type of anomaly on a non-structurally relevant element of the product, which for example only serves as a cover .

In the method according to the invention for documenting anomalies of an industrially manufactured product, in particular in the course of performing a quality check, a product is first provided and checked by a user for anomalies, in particular for defects in and / or on the product.

The method according to the invention is characterized in that a digital three-dimensional data model of the product is provided and presented to the user on a two-dimensional display surface, so that the user records an anomaly found on the product via an input device on the digital three-dimensional data model of the product shown on the display surface in such a way that When the anomaly is detected, these spatial coordinates are assigned and at least one further parameter is assigned, the spatial coordinates and the at least one further parameter of the detected anomaly forming a data record, and the data record being transmitted to a data memory and stored.

By providing a three-dimensional data model, the anomalies are no longer recorded on specific views on a raster sheet. Rather, the anomalies can be recorded by the data model in a location-specific manner with the corresponding spatial coordinates. The data model also enables the respective anomaly to be recorded more precisely, since the user no longer has to assign the anomaly to one or more views, but can record them directly on the data model. As a result, an explicitly pronounced spatial imagination of the individual user is also no longer absolutely necessary, since the position of the anomaly on the real object can be compared directly with the three-dimensional data model shown on the display surface. The user therefore no longer has to assign the anomaly found on the product to one or more side views of the product.

In particular, the three-dimensional representation can be a 1: 1 representation of the product, so that there are no different scales for the user between the real product and the three-dimensional representation of the product on the display surface.

By forming a data record comprising the spatial coordinates and at least one further parameter, the anomaly is clearly determined and can thus also be distinguished from further recorded anomalies of the same product or other products of the same shape. In addition, by recording all anomalies on the product using the recorded data records, a three-dimensional digital twin of the real product can be generated. With the digital twin, all information about a product is brought together and recorded in a three-dimensional representation. The information on a product is thus permanently stored and can also be called up and analyzed again at a later point in time without the real product still having to be available for this purpose.

Only part of the three-dimensional data model of the product on the is preferred Display area shown, in particular a component of the product. Particularly in the case of assembled products, the individual components or parts of the product can first be checked and the anomalies detected in the representations of the individual components or parts can be recorded. After the inspection of the entire product has been completed, the entire data model of the product with all components or parts can be shown on the display area.

Areas of the three-dimensional data model are preferably combined to form object zones, with identical specific requirements applying in an object zone. For example, an object zone can be formed by a uniform limit value in the event of a deviation. For example, a detected anomaly in one object zone can definitely be relevant, whereas in another object zone with a different limit value, an identical anomaly would not be able to be detected. In the representation of the three-dimensional data model, the object zones can be represented in an optically distinguishable manner, for example by means of different colors. In this way, particularly relevant areas of the product can already be made clear to the user during detection, so that the user takes particular care when detecting an anomaly in this area.

The method is preferably used when carrying out paint audits on the surfaces of a product, for example a vehicle. Furthermore, the method can preferably also be used in the documentation of rental objects, in particular rental vehicles, for documenting the condition of the rental object, for example showing dents or scratches on the rental vehicle.

A preferred embodiment of the method is characterized in that the at least one further parameter comprises a type, a size, an orientation and / or a point in time at which the anomaly was detected. The anomaly is recorded more precisely by means of the further parameters, so that there is always a clear assignment of the recorded data record to the anomaly. Furthermore, by recording further parameters, a broad database can be achieved, which later allows a more precise evaluation of the data set.

A subgroup of a specific further parameter, in particular the type of anomaly detected, is preferably shown on the display area and can be selected. As a result, the respective anomaly can be detected more quickly. In particular, by forming a group of a specific parameter, different designations, for example for the type of anomaly detected, are avoided by different users. This further improves the unambiguous determination of anomalies.

An advantageous embodiment of the method provides that further product data, in particular production data of the industrially manufactured product, are added manually to the data record using the input device on the display area and / or via an interface or linked to the data record. In this way, the detected anomaly can also be assigned to a specific product. Adding the product data to the data record or linking the product data with the data record also enables complete recording of all relevant data for the respective product. When anomalies are detected in the product at a later point in time, this allows conclusions to be drawn about how these occurred in the manufacturing process.

A preferred embodiment of the method is characterized in that the representation of the three-dimensional data model on the display area is rotated, shifted, enlarged and / or reduced by the user in order to generate a specific view of the three-dimensional data model on the display area. In this way, the user can change the view to the corresponding needs and views on the display area in order to enable a correspondingly precise detection of the anomaly in the three-dimensional data model displayed on the display area. This means that all anomalies in the product can be precisely recorded.

Advantageously, the representation of the three-dimensional data model on the display area can be cut continuously by the user in order to generate a sectional view of the three-dimensional data model on the display area. Thanks to the stepless cutting to generate the cut view, the anomalies can also be detected in the case of geometrically complex products, for example products with an undercut or a branched internal structure. The representation of the three-dimensional data model can be cut in any plane so that the desired sectional views are generated in each case. Furthermore, through the individual setting of the view and the stepless cutting of the view of the three-dimensional data model of the product, internal anomalies on the product, for example an anomaly inside a hollow body, can be precisely recorded with their specific position.

Alternatively or in combination, anomalies of one or more products that have already been recorded are shown in the data model, with in particular the detected anomalies are grouped, in particular according to their type, and displayed differently, preferably differently in color, so that each type of anomaly is preferably assigned to a color. The representation of anomalies of a product that has already been recorded ensures that all anomalies on a product are recorded without a multiple recording of an anomaly taking place. By visually comparing the product with the three-dimensional data model shown on the display area, the user always has an overview of all the anomalies recorded. In particular, this avoids multiple detection of an anomaly on the product.

The spatial coordinates of the detected anomaly are preferably assigned by selecting a specific point or area on the three-dimensional data model shown on the display area. In particular, the three-dimensional data model is embedded in a coordinate system, in particular a three-dimensional Cartesian coordinate system, as a result of which unique spatial coordinates are assigned to each point. By correspondingly selecting the view of the three-dimensional data model shown on the display area, the anomaly can be detected in particular at every point on the product. In this way, in particular through the use of a coordinate system in which the three-dimensional data model is embedded, a comparability of a large number of detected anomalies of products of one or more batches is made possible.

The anomaly and / or a change in the representation of the three-dimensional data model is advantageously detected using a touch-sensitive screen as an input device. The touch-sensitive screen can in particular be controlled by means of one or more fingers of the user, and allows intuitive and user-friendly control of the view and input of the desired parameters.

Alternatively or in addition, an input pen can also be used for input. In particular, the anomaly can be positioned more precisely on the three-dimensional data model using the input pen, as a result of which an error tolerance during input can be further reduced.

A preferred embodiment of the method is characterized in that when the anomaly is detected, at least one further file, in particular an image of the anomaly, is stored in the data memory together with the data record and is linked to the data record. The further file can also be a video of the product to be checked, measurement protocols, recorded measurement signals, data sheets and / or audio files, in particular voice recordings. The at least one further file can be in any file format. An image or a video also allows the anomaly detected to be viewed at a later date, without the product still having to be present. In particular, the additional files recorded allow the comparison of similar anomalies in different products, for example after a batch with several products has been recorded.

In an advantageous manner, the recorded data records for each recorded product are read out individually or for several recorded products together, for example the products of a batch or a test series, from the data memory and displayed on the display area on the three-dimensional data model and / or output as a list. This gives the user an overview of all the anomalies recorded and can identify agglomerations of anomalies or anomalies that limit the function, which limit the use of the product or make it impossible in the first place. From this, measures to remedy the anomalies can finally be derived.

Alternatively or in combination, the recorded data records for each recorded product are read out individually or for several recorded products together, for example the products of a batch or a test series, from the data memory and on a further display surface, in particular in data glasses, on the three-dimensional data model displayed and / or output as a list. The representation of the detected anomalies on a further display surface, in particular data glasses, enables the user to move freely around the room and additionally bring a real product into his field of vision, so that the representation of the three-dimensional data model of the product in the data glasses can be superimposed on the real product. In particular, anomalies that have already been recorded can be checked again for their specific location and correct detection.

A preferred embodiment of the method further provides that the recorded data records are read out from the data memory and evaluated according to spatial coordinates and / or at least one parameter and / or production data. By means of an evaluation, the recorded anomalies and / or the complete data sets can be displayed in a summarized manner and appropriate measures to avoid such anomalies can be derived. In particular, regions with a high number of anomalies can be identified and viewed more precisely by the user or further analyzed.

An anomaly density is preferably determined during the evaluation. In this way, problem areas on the product with an accumulation of anomalies can be identified. The user can then take another closer look at the identified problem areas and / or derive measures to remedy the anomalies. The anomaly density can refer to all types of anomalies or just a subset of the types of anomalies.

During the evaluation, the data records are advantageously selected and selectively displayed according to the type, size and / or position of the detected anomaly and / or the further parameters and / or a characteristic of the production data. In this way, the development of anomalies in a large number of events can be evaluated using individual parameters and their individual influence on the development of anomalies can be determined. In particular, this allows measures to be taken to avoid anomalies in the product. In particular, the knowledge gained can flow back into the design, whereby the design of the product can be improved to avoid design-related anomalies.

An evaluation of the data sets of the recorded anomalies of products, during the production of which different parameters were varied, according to individual or several production data also enables the influence of the production process on the development of anomalies to be determined. In this way, a manufacturing process that is optimized with regard to avoiding anomalies can be derived.

Overall, by evaluating a large number of data records on recorded anomalies of products, both the data on which the production of the product is based, in particular the design, and the production process of the product itself can be improved.

Alternatively or in combination, individual parameters and / or parameters are weighted differently in the evaluation. As a result, certain parameters can be assigned a greater influence in the evaluation.

The recorded data sets, in particular the spatial coordinates of the recorded anomalies, are preferably extracted from the data memory and transferred to a further system environment, in particular to a system for simulating and / or calculating properties of the product. As a result, the recorded data can be better evaluated in the further system environment. By transferring the data records to a system for simulating and / or calculating properties of the product, the influence of the recorded anomalies on the product can be analyzed further and, in particular, the quality of the calculation and / or simulation can be assessed and further improved. For example, the calculations and / or simulation can be used to analyze whether a product still fulfills all relevant specifications and can thus be used and sold despite the anomalies recorded. Furthermore, the objects are achieved by a system according to the invention for documenting anomalies of an industrially manufactured product, in particular in the course of performing a quality check, with a data memory in which a digital three-dimensional data model of the product is stored, and with a display means with a two-dimensional display area for Representation of at least part of the digital three-dimensional data model of the product.

Furthermore, the system comprises a control device which is connected to the data memory and the display means in such a way that a three-dimensional data model stored digitally in the data memory can be selected and displayed on the two-dimensional display surface, and an input device for detecting anomalies of the product to be checked on the digital three-dimensional one Data model of the product by a user, with spatial coordinates being assignable and at least one further parameter being assignable to the detected anomaly when the anomaly is detected on the three-dimensional data model, the spatial coordinates and the at least one further parameter of the detected anomaly forming a data set, and the data set an a data memory is transferable and storable.

In addition to the recorded anomaly, the data record advantageously includes, as at least one further parameter, a type, a size, an orientation and / or a point in time when the anomaly was recorded on the three-dimensional data model.

During the detection, a subgroup of a specific further parameter, in particular the type of the detected anomaly, can preferably be displayed on the display area and can be selected when the anomaly is detected. This allows the entry to be made quickly. In particular, the recorded anomalies, especially when anomalies on products are recorded by several users, are always designated the same, so that a different and individual description by individual users is largely prevented or even completely avoided by specifying a subgroup or a complete group of a specific parameter becomes. This also makes it easier to evaluate the recorded data records.

The input device is advantageously formed by a touch-sensitive surface of the display area. The user can only use his fingers to record the anomaly detected on the three-dimensional data model via the display area.

Alternatively or in combination, the input device further comprises an input pen for inputting and / or selecting specific points on the display area. The anomalies on the three-dimensional data model displayed on the display area can be precisely recorded using the input pen.

In a preferred embodiment, the control device can be controlled via the input device in such a way that the three-dimensional data model shown on the display surface can be rotated, shifted, enlarged, reduced and / or cut continuously to generate a sectional view. In this way, the user can use the corresponding view of the three-dimensional data model to precisely record the anomaly.

The data records stored in the data memory can preferably be read out and displayed on the display area or a further display area, the data records being selectable and selectively displayable according to the type, size and / or location of the detected anomaly and / or the further parameters and / or a characteristic of the production data are. The joint representation of all recorded anomalies of an individual product ensures that all anomalies of a product are recorded and multiple recording of an anomaly is avoided. A common display of all detected anomalies of several detected products allows the rapid identification of accumulations of anomalies, in particular when identical or at least similar types of anomalies are displayed in groups.

The data records stored in the data memory can advantageously be evaluated according to spatial coordinates and / or at least one parameter and / or characteristic of the production data, the evaluation being able to be displayed on the display area or the further display area. In particular, a statistical evaluation of the anomalies can be carried out according to their type, their size or a further parameter. Depending on the type of anomaly or its location on the object, limit values can be assigned to the group of the type of anomaly, and the recorded anomalies can only be displayed selectively if the limit value is exceeded.

Individual parameters and / or characteristics are preferably weighted differently in the evaluation.

In 3 is the representation 10 the three-dimensional data model of a product 1 on a display area 11 shown. In the present case, it is the representation 10 of a cast component as a product 1 , which is examined for anomalies as part of a quality check.

The display area 11 is part of a tablet that the user carries with him during the quality check. The use of a tablet means that the quality check is not tied to a fixed location. Rather, the quality can be checked at various stations along the manufacturing process of the cast component and not just on an end product.

The display area 11 The tablet is touch sensitive, so the user can touch the display surface 11 the representation 10 of the three-dimensional data model of the cast component can change. Changing the view of the representation 10 the three-dimensional data model is carried out in the same way as other devices with a touch-sensitive display surface 11 , for example smartphones or tablets, depending on the gesture, for example moving a finger in one direction or moving two fingers apart, the touch-sensitive display surface 11 touching fingers, the view becomes the representation 10 moved, rotated, reduced and / or enlarged. Alternatively or in addition, input areas 12th on the display area 11 arranged by means of which the representation 10 moved, rotated, can be reduced and / or enlarged or the desired sectional view can be generated. The user can use the input areas 12th thus the representation 10 set in such a way that this enables anomalies in the display to be recorded as precisely as possible 10 enables.

An anomaly detected on the real cast component is also detected via the touch-sensitive display surface 11 like this in 4th is shown. To do this, the user selects a point or an area on the display with his finger 10 of the cast component, which essentially corresponds to the position of the anomaly found on the cast component. In order to enable precise recording, the user provides the representation 10 in such a way that an optimal view for the user for detecting the anomaly found is given. Alternatively, the user can also use an input pen to record the anomaly, which enables him to record the specific position of the detected anomaly on the cast component even more precisely in the three-dimensional representation of the data model of the cast component.

The representation 10 of the three-dimensional data model, a Cartesian three-dimensional coordinate system is stored, so that each selected point of the representation 10 of the data model can be assigned unique spatial coordinates. As a result, the anomaly to be recorded is recorded in a location-specific manner. The zero point of the coordinate system is fixed at any arbitrary, but always the same point in space, so that the representation 10 is always oriented in the same way in the coordinate system.

As in 4th shown, the user has to record the anomaly 14th the representation 10 of the cast component cut at a desired point, so that the anomaly is recorded with its specific location on the three-dimensional data model and spatial coordinates are thus assigned to this point. Via the input area 12th it is possible for the user to continue displaying 10 on the screen 11 to enlarge or reduce accordingly in order to enable a more precise detection of the anomaly.

In addition to detecting the location of the anomaly on the display 10 of the cast component on the display area 11 are via another input area 12 ' further parameters of the anomaly to be detected 14th queried. Via the further input area 12 ' the type of anomaly detected 14th , for example whether the detected anomaly is 14th a cold flow point, oxide adhesion, pore, suction point or a crack is recorded. In the present case it is the detected anomaly 14th around a pore or a suction point on the cast component. Next is via the further input area 12 ' also records the size of the anomaly detected. Thus, the user initially only selects one position on the display 10 and can use the input area to determine the size of the anomaly to be recorded 12 ' without having to mark a larger area on the display. To simplify the detection, it is assumed here that the anomaly found is round and that the number is on the input area 12 ' relates to the diameter of the detected anomaly.

After entering all further parameters for the anomaly to be recorded 14th a data record with the specific location of the anomaly and the further parameters for this specific anomaly is created and stored in a data memory. Furthermore, further parameters of the production of the cast component are assigned or linked to the created data record or, after completion of the review of a cast component, all data records of this one cast component data records of recorded anomalies, so that for each cast component checked, its production parameters are known in addition to the anomalies found. This enables a better evaluation of the recorded data sets later, from which an improved manufacturing process or an improved design can be derived.

In addition, the record of the detected anomaly 14th an image of the real object with the anomaly over the input area 12 ' added. Via the input area 12 ' there is access to a camera which, when a tablet is used as a display means for the display area, is identical to the camera of the tablet. Alternatively, an external camera can also be used, which is in operative connection with the system for detecting anomalies. After the image of the recorded anomaly has been created on the real cast component, it is directly linked to the data record of the recorded anomaly 14th linked and stored accordingly in the data memory.

When anomalies are detected from a cast component, anomalies that have already been detected are detected 14 ' of the same cast component also on the display area 11 shown. This prevents anomalies that have already been recorded 14th , 14 ' , ... can be recorded again and at the same time it can be ensured that all visible anomalies on the cast component are also recorded. The user has by displaying the anomalies already recorded 14 ' constant overview of which anomalies have already been recorded and which he has not yet recorded.

In a further step, all cast components to be checked, for example the cast components of a certain batch, are checked and the anomalies detected have been recorded, all anomalies detected 14th , 14 ' , ... on the display area 11 shown. As in 5 all detected anomalies are shown 14th , 14 ' , ... with their specific position in the representation 10 of the three-dimensional data model, the different types of anomalies being shown differently in terms of color or appearance. The display of the detected anomalies 14th , 14 ' , .. . at the representation 10 can take place selectively via an input area, not shown, so that only detected anomalies of a certain type, size or another criterion with their specific location are displayed on the data model. The selection of the display of certain recorded anomalies takes place here according to all parameters of the recorded data records. So can on the display area 11 only the recorded anomalies of a certain type or all anomalies of a certain size are displayed. A selection can also be displayed based on further parameters from the manufacture of the cast components, for example the temperature or the composition of the material.

In addition to the selection of the display of certain data records, there is also an evaluation of the ones displayed on the display area 11 displayed or over all stored data sets and thus all recorded anomalies 14th , 14 ' , .... The evaluation of the data records can in turn be started via an input area, not shown, on the display area, the results of the evaluation also being shown on the display area in a specific evaluation area 13th being represented. As in 5 The evaluation was carried out across all types of anomalies recorded 14th , 14 ' , ... according to their frequency. The evaluation is also stored in a data memory and can be compared at a later point in time, for example, with the evaluation of a further batch of the same component.
