[0002] The document DE 10 2004 007 828 A1 describes a system for inspecting surfaces.

[0003] A device for inspecting surface defects is described in JP 2000 / 193601 A.

[0004] A method for surface inspection is known from the document US 5 625 197 A.

[0005] Against this background, the task was to suitably synchronize an arrangement with a conveyor system.

[0006] This object is achieved by an arrangement and a method having the features of the independent patent claims. Embodiments of the arrangement and method are evident from the dependent patent claims and the description.

[0007] The arrangement according to the invention is designed for the automatic synchronization of an action zone with a conveyor system, e.g. a conveyor belt, for a vehicle, e.g. a motor vehicle, wherein the conveyor system has a plurality of conveyor links. The arrangement has the action zone and a synchronization zone with a synchronization device for the action zone, e.g. measuring zone, assembly zone and / or processing zone, for synchronizing the arrangement and / or action zone with the conveyor system. The action zone is designed for the vehicle, e.g. for an outer surface of an outer wall of the vehicle and / or for an inner surface of an interior of the vehicle, usually for the automatic measurement, assembly and / or processing of the vehicle as at least one action that can be carried out or is to be carried out or performed automatically in and / or on the vehicle or on at least one surface.The synchronization device in the synchronization zone has at least one magnetic signal generator, which, for example, has a permanent magnet and / or electromagnet and is assigned to the at least one conveyor link. It also comprises at least one, usually stationary, magnetostrictive sensor, i.e., only one magnetic signal generator or multiple magnetic signal generators, which is designed to detect and / or determine at least one kinematic parameter or at least one kinematic variable, e.g., a position, a movement, a distance traveled, a speed, and / or acceleration, of the at least one magnetic signal generator, which moves relative to the at least one magnetostrictive sensor during operation of the conveyor system, and thus of the at least one conveyor link and of the vehicle conveyed by the conveyor system, e.g., its at least one surface.The synchronization device is designed to derive, for example calculate, at least one kinematic parameter of the vehicle from the at least one kinematic parameter of the at least one conveyor member, and to synchronize the at least one action of the action zone to be or can be carried out by the vehicle, usually in the action zone, with a movement of the vehicle, taking into account the at least one kinematic parameter of the vehicle.

[0008] The synchronization zone is usually arranged at least partially in front of the action zone, e.g., the measurement zone, assembly zone, and / or processing zone, for the vehicle, e.g., for its at least one surface, i.e., its outer wall and / or its interior, or connected upstream thereof, along a designated direction, e.g., the conveying direction and / or travel direction, of the vehicle to be conveyed, conveyable, or conveyed by the conveyor elements. It is possible for the synchronization zone and the action zone to overlap or intersect along the conveying direction. The at least one magnetostrictive sensor is arranged within a spatial detection range of a magnetic field generated by the at least one magnetic signal generator, e.g., a permanent magnet, e.g., next to and / or below the conveyor system, usually parallel to the conveyor system and / or the designated direction.

[0009] The magnetostrictive sensor can be designed and / or referred to as an extended magnetostrictive displacement transducer having two ends and configured to detect a distance between at least two points parallel to the intended direction. The sensor, e.g., displacement transducer, is arranged in a stationary manner next to the conveyor system and has, for example, a stationary base, a soft magnetic waveguide, an electrical and / or mechanical damper at a first end, and a signal converter at a second end. The signal converter is configured to convert a movement, usually mechanical, e.g., vibration, of the at least one movable magnetic signal generator and thus a movement of the magnetic field generated by it, usually inductively, into an electrical signal and to magnetostrictively determine a position of the at least one signal generator in a respective conveyor member parallel to the intended direction.The sensor or a corresponding magnetostrictive measuring element is, for example, an elongated waveguide made of a magnetostrictive material, e.g. a nickel-iron alloy, arranged parallel to the direction, wherein this, for example, tubular and / or cylindrical waveguide encloses an interior space, usually coaxially, wherein an elongated current conductor, e.g. wire, made of an electrically conductive material, e.g. copper or nickel, is arranged in the interior space.

[0010] To measure a position and / or movement of the at least one signal generator, an electric current formed from short, successive pulses is passed through the current conductor, generating a circular magnetic field that is focused in the waveguide due to the soft magnetic properties of the latter. In addition, magnetic field lines of a magnetic field of the at least one signal generator run perpendicular to the magnetic field of the current that is passed through the current conductor and thus through the sensor, wherein the magnetic field lines are or are focused in the waveguide. In a region of the waveguide in which the magnetic fields of the sensor and of the at least one signal generator overlap,The waveguide and / or the current conductor are elastically deformed by magnetostriction parallel to the intended direction, whereby a corresponding deformation of the waveguide and / or the current conductor generates mechanical waves that propagate in one direction and in the opposite direction. A first wave traveling toward one end of the waveguide is damped, e.g., damped away, by the damper at that end, whereby a second wave traveling opposite to the signal converter at the second end generates an electrical signal by reversing a magnetostrictive effect, from which the position and / or movement of the at least one signal generator is determined.

[0011] In one embodiment, the arrangement comprises a central processing unit and, in the action zone, usually at least one action device, generally an automated measuring device, i.e. only one measuring device or several measuring devices, and / or at least one automated processing and / or assembly device, i.e. only one processing and / or assembly device or several processing and / or assembly devices, which can also be combined, e.g. at least one robot, possibly with at least one tool, and / or at least one sensor, e.g. a surface sensor, for the automatic processing, assembly and / or measurement of the vehicle or its at least one surface as an action that can be carried out or is to be carried out for this purpose.

[0012] The at least one magnetostrictive sensor of the synchronization device is designed to magnetically detect and / or receive signals, usually of the generated magnetic field, of the at least one signal generator or from the at least one signal generator without contact or contactlessly, wherein the central processing unit is designed to evaluate the signals and further to control, for example to control and / or regulate the at least one action device, for example measuring device, assembly device and / or processing device, taking the signals into account, for example to provide the at least one action device with information about the at least one current kinematic parameter, at least the current position, of the at least one conveyor member and / or the vehicle conveyed thereby via signals. In an embodiment, the at least one magnetostrictive sensor, if applicable.several magnetostrictive sensors, and the central processing unit can also be arranged in one unit and / or device.

[0013] If the at least one signal generator has at least one electromagnet, it can be controlled with an electric current that has a defined temporal profile, wherein a magnetic field generated by the at least one electromagnet has a resulting, usually temporal, profile as a signal that is detected by the at least one sensor. If the arrangement has multiple signal generators assigned to multiple conveyor elements, each signal generator can generate a magnetic field with an individual temporal profile that differs from the magnetic field profiles generated by other signal generators. This means that each signal generator can be identified, usually uniquely, on the basis of its individual profile and can be distinguished from the other signal generators.This also makes it possible to clearly identify a respective conveyor element to which a signal transmitter is assigned and thus the at least one kinematic parameter of the same.

[0014] In one embodiment, the arrangement comprises m magnetic signal transmitters for a conveyor system with n conveyor links, where n and m are natural numbers, where m in one embodiment is at most as large as, for example equal to or smaller than, n. The at least one signal transmitter is arranged, attached and / or fastened to the at least one conveyor link of the conveyor system as a conveyor device and is conveyed by the conveyor system. As a rule, k*m = n, where k is greater than or equal to 1. If k is greater than 1, only each kth conveyor link is assigned a magnetic signal transmitter.

[0015] In a further embodiment, the arrangement has a position determination unit which is designed to determine and / or ascertain the at least one kinematic parameter of the at least one conveyor member of the conveyor system, i.e. its usually current position and / or speed, relative to the action zone, for example to the measuring zone with the at least one measuring device, to the processing zone with the at least one processing device and / or to the assembly zone with the at least one assembly device, and / or relative to the at least one magnetostrictive sensor. This position determination unit comprises the at least one signal generator and the at least one sensor. In addition,the position determination unit, the synchronization device and / or the central processing unit are designed to determine a distance traveled by the at least one conveyor member within a period of time depending on the relative position, speed and / or acceleration thereof.

[0016] The at least one measuring, assembly, and / or processing device as an action device in the action zone is designed to automatically traverse, measure, and / or process the outer and / or inner surface or given actual surface, usually at and / or at a predetermined distance from the respective surface of the vehicle, according to a trajectory predetermined depending on a predetermined target surface of the outer wall and / or the interior of the vehicle, when performing a respective action. A spatial position and / or orientation of the at least one surface of the vehicle can be determined based on the at least one kinematic parameter detected by a sensor. The distance to the respective surface is greater than or equal to zero.If the distance is greater than zero, the surface can be measured contactlessly and / or indirectly by a measuring device and / or processed and / or mounted by a processing device in a contactless and / or indirect manner, e.g. by coating and / or painting with a medium applied by the processing device from a distance, or e.g. by heating and / or laser welding using electromagnetic waves generated by the processing device. If the distance is zero, the surface can be directly measured, mounted and / or processed, e.g. by mechanically subjecting it to contact between the measuring, assembly and / or processing device and the surface, e.g. by mechanical interaction. It is possible to mount at least one further component on and / or for the surface when assembly is carried out. During assembly, the surface can be joined, e.g.Screwing, welding, gluing, soldering, clipping, at least one further component is arranged, usually fastened or fixed, on the surface.

[0017] The method according to the invention is designed for the automatic synchronization of an action zone with a conveyor system, e.g., a conveyor belt, for a vehicle, e.g., with an embodiment of the arrangement presented above. The conveyor system comprises a plurality of conveyor links. A synchronization zone assigned to the conveyor system comprises a synchronization device for the action zone, e.g., a measuring zone, processing zone, and / or assembly zone. The action zone may comprise at least one automatic action device, i.e., a measuring device, processing device, and / or assembly device, e.g., a robot. With this at least one action device, at least one action is automatically executed or carried out, typically in the action zone, on the vehicle, in the vehicle, and / or for the vehicle.At least one such possible action is automatic measurement, processing and / or assembly of the vehicle, wherein usually at least one outer and / or inner surface of the vehicle is automatically measured, processed and / or assembled. In this case, the synchronization device has at least one magnetic signal generator in the synchronization zone, which is assigned to at least one conveyor member, and at least one, usually stationary, magnetostrictive sensor, with which at least one kinematic parameter, e.g. a distance traveled or a speed, of the at least one magnetic signal generator and thus of the at least one conveyor member which moves relative to the at least one magnetostrictive sensor during operation of the conveyor system, is determined, recorded and / or ascertained.at least one kinematic parameter of the vehicle is derived, for example calculated, by the synchronization device from the at least one kinematic parameter of the at least one conveyor member, and the at least one action to be carried out or carried out or can be carried out for the vehicle in the action zone is synchronized with a movement of the vehicle, taking into account the at least one kinematic parameter of the vehicle, wherein the at least one action is adapted by the at least one action device to the movement and thus also to a respective position of the vehicle.

[0018] In the method, the action zone or the at least one automatic action device is synchronized relative to the vehicle or its at least one surface, which is moved and positioned by the conveyor system, wherein a movement to be performed and / or a position to be assumed by the at least one action device is adapted to a respective movement and / or position of the at least one conveyor member and the resulting movement and / or position of the vehicle conveyed thereby. The action zone can also be synchronized with the conveyor system or its conveyor members. The action zone and the synchronization zone are designed as components of the arrangement.

[0019] Typically, the vehicle conveyed by the at least one conveyor member has the same at least one kinematic parameter parallel to the direction along which the at least one conveyor member moves and the vehicle moves along with it. Taking into account this at least one parameter and a commonly known shape of the vehicle, e.g., at least one surface of the vehicle, a movement of the at least one action device relative to the vehicle is adapted and synchronized to the at least one kinematic parameter of the conveyed vehicle.

[0020] In the method, the vehicle is conveyed or transported by the conveyor links in one direction, e.g., conveying and / or travel direction, first to and through the synchronization zone and then to and through the action zone, e.g., measuring zone, assembly zone and / or processing zone. The vehicle is arranged on some of the conveyor links and is conveyed with or by them. The conveyor links are arranged on a closed belt, e.g., a conveyor belt, or along this belt or a closed chain, which is moved by a drive of the conveyor system, usually in an endless rotation, whereby the conveyor links are also moved. The vehicle, usually arranged on several conveyor links, or at least one of its surfaces, is extended along the direction, e.g., the conveying direction of the conveyor links and / or the travel direction of the vehicle.In an embodiment of the method, a position of at least one reference point of the vehicle and / or its at least one surface relative to the at least one signal generator is first determined. Furthermore, the at least one kinematic parameter, at least the position of the at least one reference point and thus of the vehicle and / or its at least one surface, is derived from the at least one parameter, at least the position of the at least one signal generator.

[0021] The method and arrangement enable synchronization with the conveyor system and / or action zone for the typically automatic measurement, assembly, and / or processing of the vehicle or its at least one surface. The vehicle conveyed by the conveyor elements is automatically moved into the synchronization zone and the action zone in the specified direction, e.g., direction of travel, generally first into the synchronization zone and then into the action zone. Furthermore, the distance traveled and / or the speed of the at least one conveyor element is automatically determined and / or ascertained using a synchronization device and the signal transmitters attached to the conveyor elements.

[0022] In a further embodiment of the method, a movement of the at least one measuring device, processing device and / or assembly device as an action device of or in the action zone relative to the vehicle, which movement is usually carried out by the robot, is monitored, for example controlled and / or regulated by a central processing unit, taking into account the at least one kinematic parameter. The movement of the at least one action device relative to the vehicle, which is usually moved by the conveyor elements or by the conveyor elements, or to its at least one outer and / or inner surface, is spatially and / or temporally correlated, taking into account the at least one kinematic parameter, it being possible for the at least one action device and / or its movement relative to the vehicle orits at least one surface, i.e. relative to the current position and / or relative to the current movement of the vehicle or its at least one surface. In this case, the specified framework conditions for synchronization can be observed.

[0023] It is provided that there is a gap and / or a hollow space between immediately adjacent conveyor links, the length of which can vary along the direction in which the vehicle is conveyed. With the method and the arrangement, synchronization with the conveyor system is possible regardless of the hollow spaces and / or jumps between the conveyor links and regardless of the length and / or elongation or change in the length of the flexible and / or elastic belt or chain to which the conveyor links are attached. The synchronization of the conveyor system is suitable and / or designed for a start / stop operation of the conveyor system. It is possible for both the signal generators and the at least one magnetostrictive sensor to be arranged in a plastic housing.The arrangement for synchronization with the conveyor system is low-maintenance because, in conjunction with magnets as signal transmitters, it is protected from contamination and / or moisture. It is typically provided that an automated measuring system, assembly and / or processing system for the vehicle has at least one automated action device in the action zone. The conveyor system, the at least one action device and the arrangement are employed or used in the production of the vehicle. The at least one action device for measuring, assembling and / or processing the vehicle can be designed as a robot or robot cell and / or arranged at the end of an assembly line and / or the conveyor system.

[0024] Taking into account the at least one kinematic parameter, the at least one action device for carrying out a measuring process when measuring the vehicle or its at least one surface and / or for carrying out a processing and / or assembly step during the processing and / or assembly of the vehicle or its at least one surface is synchronized with the conveyor system, e.g., the conveyor belt with or on which the vehicle is currently being conveyed. To determine a kinematic parameter, a mechanical encoder and / or friction wheel resting on a closed conveyor belt consisting of skids has previously been used. Since the gaps in the conveyor system exist between the conveyor elements, such a friction wheel is unsuitable for detecting a movement of the conveyor system.

[0025] Different conditions are provided for the synchronization of the conveyor system under which it should function. The synchronization of the conveyor system can be carried out with the method as precisely as possible. This works even despite the jumps and / or cavities between the conveyor links. Furthermore, the arrangement also works if the length of the belt to which the conveyor links are attached changes, or if the width of a gap between conveyor links changes over the running time of the moving conveyor links. Furthermore, the synchronization is suitable for a start / stop operation of the conveyor system. With the arrangement and the method, the synchronization with the conveyor system, usually with the belt, e.g. conveyor belt, and the conveyor links can be achieved in a stable and sufficiently precise manner. Accuracy can be ensured due to the jumps between the conveyor links or cavities.In addition, the signal transmitters and at least one sensor are not affected by any contamination over the running time, which means that there is no additional effort for regular cleaning work.

[0026] It is understood that the features mentioned above and those to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the present invention.

[0027] The invention is illustrated schematically in the drawing using embodiments and is described schematically and in detail with reference to the drawing. Fig. 1 shows a schematic representation of an embodiment of the arrangement according to the invention for a conveyor system for carrying out an embodiment of the method according to the invention.

[0028] Fig. Figure 1 shows a schematic representation of an example of a conveyor system 2 for conveying or transporting a vehicle 3, in this case a motor vehicle, during the production and / or manufacture thereof. The conveyor system 2 comprises an endlessly circulating conveyor belt (not shown in detail here), on which several conveyor links 4a, 4b are arranged. The conveyor belt is moved by a drive (not shown in detail) of the conveyor system 2, whereby the conveyor links 4a, 4b are also moved. A top side 6 and a broad side 8 of each cuboid conveyor link 4a, 4b are indicated. Furthermore, a gap 5 is located between each two immediately adjacent conveyor links 4a, 4b.

[0029] The vehicle 3 is arranged here on several conveyor links 4a, 4b and is moved along the conveyor system 2 in a direction 30, e.g. conveying and / or travel direction, which is indicated here by an arrow. Fig. 1 also shows a front flap 22, two side doors 24, a tailgate 26, and wheels 28 as components of the vehicle 3, with the vehicle 3 being moved via the wheels 28 during travel. These components form an outer surface of the vehicle 3.

[0030] Fig.1 also shows several, here two, robots 20, which serve as action devices, here for example measuring devices, assembly devices and / or processing devices, arranged on both sides of the conveyor system 2 and are designed to automatically measure, detect and scan at least the outer surface, for example an outer wall, a body, a window pane or an underbody, of the vehicle 3, but also an inner surface, for example in an interior, of the vehicle 3, to mount at least one further component on the surface and / or to process the surface. The action devices form an action zone 34, for example a measuring zone, assembly zone and / or processing zone, which are assigned to a second section of the conveyor system 2 and are provided for performing an action on and / or for the vehicle 3, for example its at least one surface.

[0031] The arrangement according to the invention comprises a synchronization zone 32 with a magnetostrictive sensor 12, which here is elongated and arranged parallel to the intended direction 30 along which the vehicle 3 is conveyed. The synchronization zone 32 is assigned to a first section of the conveyor system 2 and is arranged along the direction 30 in front of the action zone 34. A length of the sensor 12 corresponds to a width of several, here, for example, eight, conveyor members 4a, 4b parallel to the intended direction 30. Furthermore, the arrangement has several magnets integrated into the conveyor members 4a, 4b, i.e., permanent magnets or electromagnets, as magnetic signal transmitters 10, which are arranged next to one another parallel to the intended direction 30 and, during operation of the conveyor system 2 when it is conveying the vehicle 3, move parallel to the direction 30 next to the magnetostrictive sensor 12.In this case, only every third, here primary, conveyor link 4a is assigned a signal transmitter 10, for example, arranged in, on and / or on it, for example, on and / or on the broad side 8 of the respective primary conveyor link 4a and further facing the sensor 12 next to the conveyor system 2. In contrast, secondary conveyor links 4b do not have such a signal transmitter 10. Between each two primary conveyor links 4a with signal transmitters 10, two secondary conveyor links 4b without signal transmitters 10 are arranged here.

[0032] The arrangement also comprises a central processing unit 16 for monitoring, e.g., for controlling and / or regulating, the embodiment of the method according to the invention and / or the conveyor system 2. The processing unit 16 here comprises at least one computing unit for processing signals 14 from the signal transmitters 10.

[0033] During the method and operation of the conveyor system 2, the conveyor links 4a, 4b are moved along the direction 30, whereby the vehicle 3 located thereon is also moved, conveyed and / or transported along the direction 30. The magnetic signal transmitters 10 moving with the primary conveyor links 4a and the magnetic fields generated by them are detected by the sensor 12, which is arranged stationary relative to the moving conveyor links 4a, 4b. Several signal transmitters 10 arranged one behind the other along the direction 30 can be detected simultaneously by the sensor 12. In an alternative embodiment, the arrangement can have several magnetostrictive sensors arranged next to or behind one another parallel to the magnetostrictive sensor 12 and to the direction 30 or parallel to the conveyor system 2.

[0034] At least one signal 14 is generated by the sensor 12 from at least one signal generator 10 or on the basis of its magnetic field, which is detected by the sensor 12, and transmitted to the processing unit 16.

[0035] This determines, for example calculates, taking into account the at least one signal 14, at least one kinematic parameter, i.e. a current position, a current speed and / or a current acceleration, of at least one signal transmitter 10 and furthermore at least one primary conveyor element 4a with the respective signal transmitter 10. Furthermore, the processing unit 16 determines at least one kinematic parameter, i.e. for example a position, speed and / or acceleration, of the vehicle 3 conveyed or transported parallel to the direction 30 or its at least one surface, relative to the at least one measuring device, assembly device and / or processing device in and / or in the action zone 34. For this purpose, a position of at least one reference point of the vehicle 3 orits at least one surface to the at least one signal generator 10, wherein the at least one kinematic parameter of the at least one reference point and thus of the vehicle 3 and the at least one surface is determined and / or derived, e.g. calculated, from the at least one kinematic parameter of the at least one signal generator 10, for example by the at least one computing unit. In addition, the at least one measuring, assembly and / or processing device or its position and / or movement is adapted and synchronized to the at least one kinematic parameter of the at least one signal generator 10 and / or of the vehicle 3 during or for carrying out a respective action.

[0036] Furthermore, the action devices embodied here as robots 20 are monitored, e.g., controlled and / or regulated, by the processing unit 16 via signals 18. The action devices embodied as robots 20 and / or the movements to be performed by the robots 20 as action devices are synchronized relative to the at least one surface of the vehicle 3 to be measured and / or processed, which is conveyed by the conveyor system 2, via the signals 18 provided by the processing unit 16, which are based on the at least one kinematic parameter and / or signals 14 of the signal transmitters 10, when the vehicle 3 or its at least one surface is or is to be measured, e.g., scanned, assembled and / or processed, by the action devices embodied as measuring, assembly and / or processing devices.

[0037] In one embodiment, it is conceivable that each signal generator 10 has an individual magnetic field with a specific temporal, possibly periodically repeating, profile, wherein the respective signal generator can be uniquely recognized or identified based on this magnetic field and distinguished from other magnetic fields of the other signal generators 10. In this case, a respective primary conveyor element 4a, which has the signal generator 10 that can be uniquely identified based on the respective magnetic field, and / or its relative movement can also be uniquely identified. Within the scope of the method, it can be determined and / or recorded at the beginning on which uniquely identifiable primary conveyor elements 4a the vehicle 3 with the at least one surface is arranged, wherein the at least one kinematic parameter of the vehicle 3 relative to the action devices can be uniquely determined.
