Device for marking a group of electrical components

Description

-2- Markings are applied instead of separately for each component.5 For this purpose, devices of the relevant type are equipped with a receiving device for holding the group of electrical components in an array direction, in which the respective electrical components of the group are arranged in a holding state for the application of a marking to the receiving device.10 Such a receiving device has the advantage that the handling of the electrical components for the application of a marking is simplified. Thus, it is possible to assemble the electrical components into a group and hold them in this assembly by means of the receiving device. A holding state is defined by the fact that the electrical components are arranged for the application of a marking to the receiving device.Group handling of electrical components is advantageous, among other reasons, because the process of applying a marking to the electrical components can be carried out more quickly than applying markings to individual electrical components separately. For holding, clamping devices can be provided, for example, which achieve a force-fit hold. Furthermore, it is possible to hold the group of electrical components by positive locking, material locking, or any combination of positive, force, and material locking. Such a holding device ensures that the group of electrical components is held securely in a intended position so that marking can be carried out in the desired manner. Furthermore, devices of the type in question are equipped with a marking device that has a laser head for emitting a laser beam to apply a marking to the group of electrical components held by the holding device.The use of a laser beam enables very precise application of markings to electrical components. This is particularly advantageous in applications where the marking must be applied directly to the electrical component. BE2024 / 5919 -3- By directly applying a marking to the respective electrical component, it is avoided that a marking plate or label with a marking already applied to it must first be created and then mounted or attached to the respective electrical component. Consequently, it is possible to save processing / handling operations, thus facilitating cost-effective marking. Moreover, it is possible to minimize the errors and problems that may arise from the aforementioned processes. By using a laser beam, precise marking can be applied.For applying a marking to various locations of the group of electrical components, devices of the type in question are equipped with a 15 movement device for generating relative movements between the laser head and the receiving device in order to position them relative to each other for the purpose of applying the marking. To apply a marking, the device moves the laser head into a corresponding marking position in order to direct the laser beam at the desired location of the group or the relevant electrical 20 component. The marking position is one in which the distance between the laser head and the electrical component to be marked is reached or set for applying a marking to it. Within the scope of the invention, it is particularly provided that the distance between the laser head and the electrical components to which a 25 marking is to be applied is the same, and so that the laser beam is always kept essentially the same length until it strikes the electrical component.This ensures that the focus position is maintained at the same distance from the laser head in various marking positions. The known motion devices include drives, which can be implemented as electric, pneumatic, and / or hydraulic drives, as well as drives with any combination of these drive types. Furthermore, such motion devices regularly include gears that are operatively connected to the drive in such a way that they convert the drive movement into a relative movement between the laser head and the receiving device. The implementation of such motion devices is known and therefore requires no further explanation. BE2024 / 5919 -4- To control the motion sequences between the laser head and the receiving device, devices of the relevant type are equipped with a control device for controlling the motion device to execute a relative movement between the laser head and the receiving device.The control device is technically connected to the motion control device, which can be implemented electrically, as well as signal- or data-technically.10 Such a control device can perform further tasks, for example, and in particular, the control of the marking device or the laser head, thereby simplifying the coordination of the necessary actions for handling and applying a marking.15 Devices of the type in question are known, for example, from WO2017125364 A1, EP3405941A1, WO2010 / 057768A1, and also EP3946961B1. The known devices of the type in question serve to apply a marking to a group of electrical components, whereby this is associated with a correspondingly high control effort20 for coordinating the components involved in applying the marking in both known devices of the type in question.Against this background, the invention is tasked with reducing the control effort while maintaining or increasing the precision of marking at least at the same level. 25 To solve this task, the invention departs from the approach of using more easily controllable components to realize such a device. Furthermore, the invention departs from the approach of reducing the usability of such a device and limiting it to specific electrical components through specialization. 30 Moreover, the invention departs from the approach of reducing such a device to specific markings in order to reduce the control effort. Finally, the invention departs from the approach of applying markings to the group of electrical components in a uniform, identical, predetermined orientation or of marking only a portion of the 35 electrical components.BE2024 / 5919 -5- The invention solves the problem set out in it in a surprisingly simple way5 by the fact that the motion device is set up and designed in such a way that the laser head is guided along a path of movement for positioning the marking, by which it performs an orbital movement around the group of electrical components held by the receiving device. According to the invention, it is provided that the motion device has at least 10 a first guide element which is set up and designed for guiding the laser head along an orbital path of movement around the receiving device. This moves the laser head around the receiving device to assume a marking position, in which the laser head is positioned for applying the marking. As mentioned previously, this allows the laser head to be moved into various marking positions, in which it is positioned for applying the marking.the group of electrical components arranged therein is aligned for the application of a marking. 20 According to the invention, this has the advantage that the device can be precisely tuned to the orbital movement of the laser head, which, unlike a movement of a group of electrical components, does not form unknown masses or mass distributions, but rather the device can be precisely tuned to a corresponding movement of the laser head based on a previously known mass distribution. 25 This also makes it easier to coordinate the necessary movement sequences with each other. This results in the further advantage that the risk of under- or over-dimensioning the moving components and the affected parts of a device is minimized or avoided. 30 According to the invention, this enables quick and precise application of a marking, since the inertia of the moving masses can be specifically taken into account or compensated for, thus avoiding positioning or marking errors.Furthermore, this makes it possible to relieve the load on the corresponding drives and adjust their performance accordingly 35 BE2024 / 5919 -6- or to use less powerful drives. This allows the costs to be reduced accordingly. Therefore, the invention also offers the advantage that the movement sequences for applying the marking can be more precisely coordinated and implemented. The movement guidance of the laser head can be implemented in 10 different ways within the scope of the invention. Thus, it is possible for the first guidance element to comprise various actuators that interact with each other in the manner of a gearbox to enable movement guidance. Furthermore, according to the invention, as a supplementary or alternative option for controlling the movement sequence, it is possible to realize a predetermined guide path, for example by means of a guide rail and a corresponding rail layout, by means of individual actuators which are arranged to be movable relative to each other.This makes it possible to mechanically define or determine the orbital motion path. Furthermore, within the scope of the invention, it is possible to use coupling and cam gears to define 20 motion sequences and paths. In an advantageous further development of the invention, it is therefore provided that the first guide element has at least one guide body on which a guide path for the motion guidance of the laser head is set up and formed. 25 The invention thus realizes the advantage that the motion guidance is simplified by defining the guide path through a design or shaping of a guide body. This significantly reduces the control effort and the number of necessary guide elements, their coordination, and also the maintenance effort. 30 This can be achieved, for example, and in particular, by a guide rail that rigidly defines the orbital motion guidance of the laser head through its shape.The invention allows the orbital motion path to be realized in a variety of ways, in that its course can be designed, for example, and in particular, with a constant or variable curve radius(s). Thus, within the scope of BE 2024 / 5919 -7-, it is possible, for example, and in particular, to design the orbital motion path as elliptical or circular. Within the scope of the invention, it has been shown that the control effort for guiding the movement of the laser head can be further simplified by designing the orbital motion path as a circular motion guide. In a further advantageous embodiment of the invention, it is provided that the first guide element guides the movement of the laser head at least section by section at a substantially equal distance to an axis of rotation. In addition to reducing control effort, the invention also enables a simple and cost-effective production of an orbital motion guidance system.The invention allows the axis of rotation to be aligned in different orientations. For example, it can be aligned at an angle to the receiving device or the alignment direction in which the group of electrical components can be arranged in an operating state or in a holding state. Within the scope of the invention, an operating state is characterized by the fact that the device for applying a marking to one or more of the components is ready for operation and is set up and designed accordingly. According to the invention, a holding state is one in which the group of electrical components is held on the receiving device for applying a marking, for example, and in particular, by means of a carrier, preferably a mounting rail. To further simplify the coordination of the individual processes, it has proven advantageous within the scope of the invention that the axis of rotation is aligned parallel to the alignment direction of the electrical components.In a further advantageous embodiment of the invention, it is provided that the 30 receiving device is configured and designed such that, in a holding state in which the group of electrical components is held by the receiving device for the application of the marking, the alignment direction of the electrical components is parallel to the axis of rotation. According to the invention, this simplifies the movement sequences and their coordination. Furthermore, it further reduces the control effort. BE2024 / 5919 -8- Electrical components can have different dimensions, so that 5 a group of electrical components can be formed by differently shaped electrical components. Within the scope of the invention, the term parallel also includes a coaxial arrangement, which, within the scope of the invention, can result at least temporarily from a corresponding arrangement of the axes relative to each other.10 This results in high demands on the flexibility of a corresponding device if a broad spectrum of electrical components, especially groups of them, is to be marked. According to the invention, various implementation options can be used to meet these requirements. 15 For example, it is possible to arrange the laser head with sufficient distance to the receiving device for the group of electrical components and to adjust the laser power according to the distance of the laser head to the receiving device. The invention departs from the approach of providing a fixed, predetermined design or arrangement of electrical components through a further advantageous development. 20 This allows for a high degree of variance in the designs and dimensions of electrical components for use with a device according to the invention.The invention achieves maximum flexibility for use with various groups of electrical components by providing the movement device with a lifting element that is designed and configured for a lifting movement of the receiving device relative to the laser head. The advantage achieved within the scope of the invention is that a correspondingly designed device can flexibly mark various shapes and deviations in shape of electrical components or assemblies of such groups of electrical components. Furthermore, this avoids the risk of collision between the laser head and the electrical component. BE2024 / 5919 -9- Furthermore, the invention opens up the possibility of precisely marking the group of electrical components at various locations.The invention thus realizes the advantage that the laser power can be kept at a constant level while the arrangement of the group of electrical components relative to the laser head is adapted with respect to the location where a marking 10 is to be applied, in order to apply the relevant marking to the relevant electrical component in a given marking position. Accordingly, a marking position within the scope of the invention is, in particular, one in which the laser head is arranged relative to the group of electrical components for marking 15 on at least one of the electrical components. This makes it possible to adjust the laser power to a correspondingly low level, so that, in addition to the realization, the operation of an invention-related device can also be cost-effective and energy-efficient. 20 Furthermore, the invention thus makes it possible to adjust the distance of the laser head to the respective electrical component orto keep the group of electrical components constant so that the focus position can be maintained at a constant distance from the laser head in the marked positions. The receiving device is adjustable or movable by means of the lifting mechanism and the lifting movement of the receiving device thereby enabled, in particular between a near position, in which the receiving device is close to the laser head, and a far position, in which the receiving device is arranged far from the laser head. Within the scope of the invention, it is possible for the lifting movement to occur in various directions. It has been shown within the scope of the invention that this can be advantageously guided along an axis of movement. This has the advantage that a preferred direction is predetermined and thus a precise alignment of the movement guidance is realized. Within the scope of the invention, the lifting movement can thus be aligned in a radial direction to the axis of rotation or in a direction parallel to it.BE2024 / 5919 -10- The lifting movement within the scope of the invention is preferably translational, 5 in particular rectilinear, so that it can be, for example, and especially in an embodiment as a linear guide for rectilinear motion guidance for the receiving device. The lifting movement within the scope of the invention is not limited to an exclusively vertical or exclusively horizontal direction of movement. 10 In a further advantageous embodiment of the invention, it is therefore provided that the lifting movement is guided along a movement axis directed towards the laser head. The invention thus achieves the advantage that the distance between the group of electrical components or one of the electrical components on which a marking is to be applied can be adjusted very easily and 15 yet precisely by means of the lifting element. Furthermore, the control device can thus keep the lifting movement to a minimum. This makes it possible to quickly and precisely adjust the focus of the laser radiation emitted by the laser head.to precisely adapt to the respective requirements or to adjust the length of the laser beam until it strikes the relevant electrical component. To increase the service life, the invention includes the option that the laser beam is formed by a solid-state laser, in particular a diode laser. Furthermore, the invention includes the option that the laser beam is formed by a fiber laser. The invention has the advantage of guiding the laser beam to the laser head by means of an optical fiber, in particular a glass fiber, and emitting it accordingly. Within the scope of the invention, an optical fiber is one that guides the laser radiation. To simplify the arrangement of the laser head relative to the receiving device, the invention includes the option of using a fiber optic cable.In a further advantageous embodiment of the invention, the motion device is provided such that it moves the lifting element in a coupled manner, in particular synchronously, for motion guidance along the orbital path of the laser head, in particular in such a way that it moves the lifting element in a path parallel to the orbital path of the laser head. BE2024 / 5919 -11- The invention thus succeeds in keeping the receiving device in a predetermined position while the further motion elements or the laser head are moved / are moved or are arranged relative to the receiving device or the group of electrical components arranged thereon. The invention thus achieves the advantage that the motion control is simplified, since unnecessary positions between the laser head and the receiving device for the application of a marking are avoided.Furthermore, due to the kinematics considered by the invention, it is possible to improve the precision for applying a marking to a group of electrical components. This is made possible, among other things, by the fact that the inertia of the masses is known through the known weights of the individual components moved according to 15, whereas in practice, for the realization of a wide range of applications, the weight of the group of electrical components is different and therefore undefined. Thus, the invention succeeds in matching the individual components of a device to the individual movement options 20 very precisely and with minimal effort. In the industrial sector, the application of markings to electrical components is subject to a wide range of high requirements. Another criterion of great importance in the industrial sector is the economical operation of a device. The invention meets these requirements, among other things, due to the 25 previously mentioned previously known moving masses, which also reduce the implementation effort.However, in the course of the invention, it has become apparent that, among other things, the space or footprint required for setting up and operating such devices is very large.30 Furthermore, it has become apparent that the control effort increases with a smaller space requirement. Due to the reduced movement spaces, however, a device designed within the scope of the invention requires only a smaller footprint. This is achieved by not only moving the group of electrical components relative to the laser head for the purpose of attaching a marking or moving it to assume a desired marking position, but also by guiding the laser head along the group of components in a translational movement. Thus, the invention succeeds in keeping the space requirement small or minimal, at least in the translational direction of movement.Moreover, the invention succeeds in reducing space requirements and the risk of incorrect application of a marking by reducing the degrees of freedom of movement, which, with known implementation approaches, leads to deviations and risks of marking errors due to a plurality of distributed mass inertias or freedoms of movement. Within the scope of the invention, electrical components are in particular those which have a housing for enclosing electrical components. Within the scope of the invention, an electrical component also includes a housing for enclosing electrical components. Electrical components are, for example, those which are set up and configured for the realization of an electrical circuit. Within the scope of the invention, these can be individual electrical components, such as resistors, capacitors, relays or other switching elements, which are or can be arranged individually or in an electrically functional group in such a housing.Electrical components can be arranged together in such a housing, particularly in an electrical assembly. Furthermore, electrical components are electrically interconnected to implement an electrical circuit and can, for example, be components of a printed circuit board or a circuit carrier. Thus, within the scope of the invention, electrical components also include circuit carriers or printed circuit boards arranged in a housing. Typical and widespread examples of such electrical components are established under the term terminal block. Within the scope of the invention, such electrical components also include electrical assemblies, which are formed, for example, from circuit modules, printed circuit boards populated with electrical modules, or populated or unpopulated printed circuit boards with conductor tracks formed on them.35 BE2024 / 5919 -13- Therefore, electrical components of the type in question are particularly sensitive5 to external influences, such as vibrations and other environmental influences. Furthermore, as already mentioned, high demands are placed on the marking of electrical components, so that it must be ensured that these markings are, for example, and in particular, precisely positioned, clearly recognizable, and permanently affixed to them.10 Against this background, the invention also aims to expose the electrical components to as few vibrations as possible, or only to minimal vibrations. The invention provides for reducing the number of movement processes for marking the group of electrical components to a minimum. A marking also comprises a plurality of markings that are to be applied to one, a plurality, or all electrical components. According to the invention, this can be applied to the group of electrical components in various ways.Within the scope of the invention, it is provided that all electrical components of the group, as well as just one or a plurality of electrical components of the group in question, are provided with a marking. Thus, within the scope of the invention, it is possible to provide a selection of electrical components with a marking. Furthermore, within the scope of the invention, it is possible to apply various markings to the electrical components. Therefore, the invention includes the option that the group of electrical components, with respect to each individual component, can be provided with different or even identical markings by means of a corresponding device or method. Markings can be very different and in a wide range of design possibilities. Markings can be – as mentioned at the outset – for example, and in particular by means of signs, symbols, lines, areas, colors / contrasts, patterns and the like, as well as any combination thereof.The composition of the aforementioned components is formed. 35 BE2024 / 5919 -14- Within the scope of the invention, it is provided, for example and in particular, that the 5 laser head emits a laser beam which, upon striking a marking surface of one of the electrical components, causes a color or contrast change. For this purpose, it is generally known to provide marking surfaces on electrical components that allow the application of a corresponding marking. 10 Such a marking surface can also be formed directly on the housing of an electrical component, so that the beam emitted by the laser head is directed accordingly onto these marking surfaces. Such marking surfaces can be formed, for example, by separate marking or identification plates, as well as marking labels and the like, 15 which are or can be detachably or permanently mounted on an electrical component.Under the influence of the laser radiation emitted by the laser head on such a marking surface, a marking is generated and thus applied to the respective electrical component. 20 The design of a marking surface can be carried out in a variety of ways. Corresponding implementation options are known from the prior art, to which reference is made here. Within the scope of the invention, it is also possible, against this background, to direct the laser beam directly onto one or more electrical components of the group 25 in order to apply a marking in an alignment of the laser head to the receiving device. Within the scope of the invention, it is possible to directly provide or determine a marking surface provided on the respective electrical components by directing the laser beam onto this marking surface 30. For this purpose, the laser head is brought into a suitable position by the kinematics provided within the scope of the invention in order to assume a corresponding marking position.Therefore, the motion sequences and their coordination are of high importance and have a significant influence on the quality of the marking of the electrical component(s). Within the scope of the invention, the term control also includes a regulation by which, for example, and in particular, the motion sequences can be initialized or controlled and also corrected with regard to their execution. To perform the control tasks, within the scope of the invention, a control device is technically connected to the drives or actuators for the realization and coordination of the motion sequence control. In particular, current, signal and data lines can be used to connect the drives or actuators with the direction of motion. Furthermore, such a connection can be wireless. Therefore, in addition to the motion device, the marking device or the laser head for applying a marking can also be controlled or regulated by the control device.Within the scope of the invention, the receiving device is configured and designed in one embodiment such that the components are provided as a group of electrical components, for example, and in particular, by means of a carrier of the device, and the carrier holds the group of electrical components. Furthermore, within the scope of the invention, the option is also considered that the receiving device holds the electrical components as a group, which are supplied to it individually, in a plurality, or as a group of individual and / or subgrouped electrical components, which are then held accordingly as a group or in a composite for marking purposes. According to the arrangement, the electrical components are grouped in a row and held together in such a combination.An advantage of the invention is that the application of a marking with the advantages of the invention can be carried out in such a way that a carrier realized by a mounting rail with the electrical components arranged or snapped onto it can be installed directly, for example and in particular, in a control cabinet. 35 BE2024 / 5919 -16- This results in numerous advantages, including the reduction of the handling operations for the group of electrical components marked with a marking. Furthermore, errors caused by an erroneous arrangement or grouping of electrical components are avoided. Within the scope of the invention, it is preferably provided that its receiving device is configured and designed in such a way that it holds a group of electrical components arranged on a support, in particular on a support rail, preferably on a DIN rail. This advantageously makes it possible to achieve a simple form of support or...The holding body securely holds the electrical components in a series arrangement relative to one another.15 Therefore, these components are designed individually and / or as a group such that they can be snapped onto a support rail. A further advantageous option of the invention provides that the receiving device is configured and designed such that it securely holds the group of electrical components arranged thereon in a series arrangement by using a support rail to arrange the group of electrical components in a direction of alignment thereby predetermined. In a further advantageous embodiment of the invention, the receiving device is configured and designed to receive a support, in particular a support rail, onto which the group of electrical components can be arranged or is arranged in a holding state.With this option, the invention offers the advantage that the arrangement of electrical components can be carried out at an early stage and independently of any specific device by means of a mounting rail. Advantageously, the invention thus enables the group of electrical components to be transported to different processing stations by means of a mounting rail, since this rail can be removed from the receiving device without damage and preferably without tools. Furthermore, the invention advantageously enables a group or arrangement of electrical components in the respective arrangement configuration BE2024 / 5919 -17- to be marked and this group of electrical components to be made available with the mounting rail, for example, for installation in a control cabinet. Against this background, the invention succeeds in reducing the number of defects orThe risk of errors for the proper application of a marking to the electrical components is significantly reduced compared to the application of markings to 10 individual electrical components – among other reasons, due to the fewer handling operations. Finally, the invention also allows for meeting high economic demands for the application of a marking to a group of electrical components.15 Within the scope of the invention, holding a support rail with a group of electrical components arranged on it can be achieved in many ways. For example, and in particular, a mechanical connection can be provided to keep the support rail or the group of electrical components arranged on it free from damage.20 The range of implementation options is not limited within the scope of the invention and is known to a person skilled in the art. In the context of industrial application, however, it is necessary that the holding is ensured and, in particular, that an unintended change of position or damage is prevented when applying a marking.a change in the position or orientation of the electrical components is reliably prevented. This places corresponding demands on the holding means. According to the invention, it is possible to enable holding even under the influence of a magnetic force on the support rail. This is because the support rails, which enable an arrangement of electrical components, are often made of metal, and thus a magnet can achieve a holding effect in conjunction with the support rail. Mounting rails of the type in question are also known as so-called DIN rails or top-hat rails and are established in the context of control cabinet construction or in the context of control cabinet assembly with electrical components. 35 BE2024 / 5919 -18- In a further advantageous embodiment of the invention, it is provided that the 5 movement device has a second guide element which is set up and designed in such a way that the receiving device is held rotationally fixed at least during the relative movement between the laser head and the receiving device.The invention thus succeeds in reducing the effects of inertia on the precision of applying a marking to the group of electrical components 10. This facilitates the application of a marking that meets requirements. Furthermore, the invention succeeds in reducing the control effort. The rotationally fixed mounting contributes significantly to this, whereby tolerances or deviations in positioning can be eliminated. In a particular embodiment of this further development, it is optionally provided that the receiving device is arranged rotationally fixed to the device and thus the degree of freedom of movement of the receiving devices is correspondingly reduced. An implementation option is also considered within the scope of the invention in that the receiving device is mechanically fixed with respect to a rotational movement about its longitudinal axis.The longitudinal axis is extended, in particular, in the direction of the alignment direction specified by the device, along which the electrical components can be arranged or are arranged on the receiving device. 25 To increase flexibility, a further advantageous embodiment of the invention is provided, characterized in that the movement device has a third guide element, which is designed and configured for translational movement guidance of the laser head, wherein the translational movement guidance is directed parallel to the alignment direction. 30 This allows markings to be applied flexibly and quickly to the individual electrical components of the group by means of a device according to the invention. Furthermore, this enables precise movement guidance of the laser head. According to the invention, the movement guidance of the laser head is, for example, and in particular, linear, so that the third guidance element can be set up and designed in a BE2024 / 5919-19 realization of an optional linear guidance for the laser head.To implement various movement options, a further advantageous embodiment of the invention provides that the control device is configured and designed to prioritize the movement paths with respect to the orientation of the laser head for the application of markings, 10 by giving priority to a translational movement over an orbital movement. Within the scope of the invention, the term control – as explained above – also includes regulation. A control device therefore serves in particular to monitor the movement sequences as required with regard to their execution 15 or to adapt and correct them. According to the invention, with this option a translational motion is given preference over an orbital motion, whereby the invention achieves the advantage of precise and at the same time motion guidance by cleverly minimizing the effect of mass inertias on the motion accuracy or positioning accuracy.Within the scope of the invention, it has been shown that unfavorable mass distributions and movements, caused by corresponding mass inertia, lead to undesirably strong vibrations of a device and jeopardize the precision of marking or slow it down due to the necessary measures for vibration reduction. In this respect, the invention succeeds in optimizing and concentrating the mass distribution in such a way that the vibration excitation can be kept very low, and thus corresponding measures for vibration reduction can also be kept to a minimum and designed efficiently. Optionally, within the scope of the invention, it is provided that the corresponding steps for executing the prioritization of the directions of movement are precisely determined within the control device, for example, and in particular, by an algorithm or program sequence.According to the invention, it is also considered as an option that the 35 control device has a computing unit to execute the necessary instructions for initiating the necessary steps for the 5 marking application. Against this background, a further advantageous development of the invention provides that the control device is configured and designed in such a way that it processes data provided via data storage and / or a network connection for controlling the motion device. Thus, within the scope of the 10 invention, a correspondingly designed device offers the advantage that the necessary program steps can be provided and adapted very flexibly. Furthermore, it is thus possible to provide data from a data storage device of the control device remotely via a network connection.Accordingly, it is also possible to perform remote maintenance by means of such a device design in order to react quickly to malfunctions or unusual operating events. Furthermore, it is possible to remotely control the processes of such a device by designing the data or signal connection bidirectionally. Special stresses as well as wear phenomena lead to deviations arising during the operation of such a device, which contribute to an impairment of the processing result. Therefore, within the scope of the invention, it is provided to counteract such impairments by an adapted laser beam guidance or positioning of the laser head relative to the group of electrical components.Accordingly, the invention also includes an implementation option in which the control device comprises a detection element for optical detection of a marking area (30) on which the laser beam is directed for applying the marking in an irradiation position, which is configured and designed such that, following optical detection of the marking area (107) (schematically symbolized by a dot), an evaluation of actual marking parameters is carried out based on stored target marking parameters (35), wherein, in the event of a deviation from the BE2024 / 5919-21 marking parameters, the control device activates the movement device to adjust the irradiation position (5). Regarding the deviations, the invention also includes the option that these are determined based on preset tolerance values ​​between target and actual values. Marking parameters are, in particular, geometric quantities such as distances or dimensions, as well as such as those that align the laser head to the electrical component or...the 10 group of electrical components. The aforementioned implementation option offers the advantage that the device in question can react to deviations in the movement sequence, in particular automatically. As a result, it is possible to apply the desired markings to the 15 individual electrical components even under exceptional stress. The invention thus achieves a high reliability for applying a marking. Furthermore, this option also offers the advantage that the device according to the invention is capable of performing calibration processes, in particular to carry them out automatically. Thus, the invention 20 advantageously achieves a rapid and, in particular, autonomous adaptation of the movement sequences to occurring deviations. The implementation of this option is possible within wide limits. For example, sensors, especially optical sensors, such as camera or...Video equipment is intended to help detect corresponding deviations, which can then be evaluated by the control unit. This makes it possible for the control units to take the necessary action. Furthermore, it is possible to evaluate the detected deviations at a later time in order to make targeted adjustments to a device according to the invention. It is also provided that the device, in an operating state, comprises a mounting rail with a group of electrical components arranged thereon, in order to provide at least one of these electrical components with a marking. The provision or use of a mounting rail offers the advantage that the 35 electrical components arranged on it can be installed directly in a control cabinet after affixing a marking BE2024 / 5919 -22-. This leads to handling and logistical advantages, as already mentioned.----Operating Method for the Device---- The invention also comprised a method that is usable for operating a device according to the invention. This makes it possible to put a device according to the invention into different operating states.10 A method according to the invention for operating a device therefore comprises the following steps: - Providing a group of electrical components which are arranged one after the other in a series on a support rail - Holding the group of electrical components by means of a receiving device15 into a holding position for marking the electrical components - Moving a laser head by means of a movement device into a first irradiation position for applying at least one marking to at least one of the components by means of a laser beam20 emitted by the laser head, wherein for the irradiation position at least the laser head moves along the group of electrical components and / or in an orbital The movement path is moved around the group of electrical components.-Moving laser head by means of the movement device into a second irradiation position for further marking of the group of electrical components. According to the invention, advantageous control possibilities for the necessary movement sequences arise through an inventive method, which thereby ensures a targeted, precise and also rapid application of markings or a marking on the group of electrical components.30 Furthermore, it is possible to specifically adapt the individual steps and thus ensure a quality of execution for the operation of a device according to the invention. BE2024 / 5919 -23- Within the scope of the invention, it is also possible for the control device5 to fully and autonomously execute the individual steps without requiring further, in particular manual, intervention. Furthermore, it is possible to adapt the steps in a timely manner to changed requirements by means of the aforementioned network connection.As further options, the invention provides a further step in which the 10 receiving device is moved by means of the lifting mechanism by a, in particular translational, preferably linear, lifting movement towards or away from the laser head in order to adjust the distance of the receiving device to the laser head. According to the invention, this advantageously achieves that, for the purpose of attaching 15 a marking to the group of electrical components, the distance and the alignment between the laser head and the respective component with regard to the focus of the laser beam can be adjusted reliably, quickly and precisely. This ensures that the device according to the invention can be operated in such a way as to be able to react flexibly to different arrangements of electrical components. 20 This ensures that both the method and a device according to the invention meet a wide range of requirements.The receiving device is thus – as already explained elsewhere – adjustable or movable between a near position, in which the receiving device is close to the laser head, and a far position, in which the receiving device is arranged far from the laser head. The invention is further described with reference to the figures, whereby the explanations of the device and the method are mutually transferable. Accordingly, the features of a device can characterize a method, just as the features of a method can characterize your device. In the figures, an embodiment of the invention is shown to illustrate a relevant device as well as a relevant method. However, the invention is not limited to the constellation used therein. The representations in the figures are not necessarily to scale – especially in relation to each other – 35 BE2024 / 5919 -24 – and are concentrated particularly on the components to illustrate the 5 invention.Accordingly, all claimed, described, and depicted features, both individually and in any combination, constitute the subject matter of the invention, irrespective of the constellations and dependencies shown in the description or depiction in the drawing. Therefore, the features are not bound to the constellation explained below, but can also form an object recognition method according to the invention in isolation from one another, as well as in a different combination or constellation. The figures in the drawing show the aforementioned embodiment of the invention by means of schematic representations. The representations in the figures are therefore not necessarily to scale, so that, among other things, the scales chosen in the figures may differ from one another. Furthermore, identical or corresponding components / parts or elements in the figures are provided with the same reference symbols.For clarity, not all elements / components / parts in the figures are always labelled with reference symbols, the assignment being clear from the identical representation or a representation adapted to the view.

Furthermore, a third irradiation position is illustrated in Fig. 8. Fig. 9 of an inventive method for operating the device from Fig. 1. Fig. 1 showed an embodiment of a device 10 according to the invention for 5 marking a group of electrical components (in Fig. 1 to Fig. 1).4 (not shown) in a perspective view, in an operating state. The embodiment of a device 10 according to the invention is hereinafter also referred to as device 10 for short. Within the scope of the invention, such an operating state is characterized 10 by the fact that the device 10 is ready for operation to apply a marking to one or more of the components and is accordingly set up and designed. Furthermore, a holding state results in which the group of electrical components is held on a receiving device 15. For this purpose, in particular the electrical components are snapped onto the support rail. Therefore, 15 a device 10 shown in the figures comprises at least in a holding state a aforementioned carrier with a group of electrical components arranged on it, in particular a group of electrical components snapped onto a support rail. This is illustrated with reference to Fig. 5 to Fig. 8.The device 10 is therefore equipped with a receiving device 15 for holding a group of electrical components in an arrangement direction 20, which is defined by the receiving device 15 of the device 10 and in which the electrical components are arranged in a holding state relative to one another. The invention includes the options that a group of electrical components is supplied to the device 10 in a group arrangement and / or that the group is formed or supplemented by arranging individual or a plurality of electrical components on the receiving device 15, as well as being adapted or can be adapted. For the purpose of applying a marking to at least one of the electrical components, the device 10 is provided with a marking device 2530, which has a laser head 30 for emitting a laser beam 35 (symbolized in Fig. 1 by BE2024 / 5919 -27- by a dashed line) for applying a marking to the group of electrical components held by the receiving device 15.The laser beam 35 is to be aligned accordingly for the application of a marking to the relevant electrical component or aligned in a marking position (see Fig. 5 to Fig. 8). In order to align the laser beam 35 accordingly, the device 10 is equipped with a movement device 40 for generating relative movements between the laser head 30 and the receiving device 15 in order to position them in a marking position relative to each other for the application of the marking. Furthermore, the device 10 is equipped with a control device 45 for controlling the movement device 40 for the relative movement between the laser head and the receiving device 15 in order to move them into a marking position for the application of markings to the group of electrical components. For this purpose, the control device 45 (symbolized by a rectangle) is technically connected to the respective components to be controlled. This is shown in Fig.1. Dashed lines between some of the depicted drive motors 46 (equated with the same reference numeral), which serve to generate the necessary drive movements, and the control device 45 symbolize this. Furthermore, the control device 45 is configured and designed to control the marking device 25 or the laser head 30, thereby simplifying the coordination of the necessary actions for handling and applying a marking according to the invention. The relevant control-technical connection is symbolically illustrated in Fig. 130 by a dashed line between the control device 45 and the marking device 25. In this embodiment, the control device 45 is configured and designed to prioritize the movement paths relating to the orientation of the laser head 30 for applying markings such that a translational movement takes precedence over an orbital movement 35.Furthermore, the control unit 45 is configured and designed in such a way as to process data provided via a data storage device 47 (symbolized by a cylinder) 5 and / or a network connection 49 (symbolized by a circle) for controlling the motion device 40. For this purpose, the data storage device 47 or the network connection 49 is connected to the control unit 45 (symbolized by lines in Fig. 1). The control unit with the network connection and the data storage device 49 10 or the network connection 49 are not shown in the following figures for clarity, but are illustrated only in Fig. 1 as a representative example. The motion device 40 has at least one first guidance element 50, which is designed and configured for guiding the movement of the laser head 30 along an orbital motion path 55 (symbolized by a dashed circular double arrow in Fig. 115) around the receiving device 15.This makes it possible to apply a marking to different locations on an electrical component, or to make these locations accessible by the laser beam 35. To realize the orbital motion guidance of the laser head 30 around the 20 receiving device 15, the device 10 provides that the first guide element 50 has at least one guide body 60, on which a guide track 65 for the motion guidance of the laser head (30) is set up and formed. In this embodiment, two guide bodies 60 are present, which are uniformly marked with the reference numeral 60. Furthermore, the respective guide tracks 65 located on them are marked with the same reference numeral 65. The guide bodies 60 are spaced apart from each other in the direction of the alignment direction 20. In this embodiment, they are identically designed and connected to each other for synchronizing the orbital motion guidance.To support motion control, the device 10 has a counterweight 7030 to compensate for the weight of the marking device 25 guided by the guide body. This makes it possible to design the drive train 75 for motion generation with correspondingly less powerful components compared to a solution without a counterweight 70 and to implement the motion control more simply. In this embodiment, the counterweight 7035 is distributed in the direction of alignment into two components, which are provided with the same reference numeral 70. BE2024 / 5919 -29- The device, through the two first guide bodies 60, ensures that the first 5 guide element 50 guides the movement of the laser head 30 at least sectionally at a substantially equal distance to a rotation axis 80 (symbolized in Fig. 1 by a dashed-dotted line). In this embodiment, the orbital path of motion is circular and at the same distance to the rotation axis 80.The first guide element 50 is configured and designed such that the orbital 10 movement takes place in a partial circle, since 360-degree movement guidance is not necessary. This allows the device 10, or rather the first guide element 50, to be designed accordingly more simply. Furthermore, the device is characterized in that the receiving device 15 is configured and designed such that, in a 15 holding state (illustrated with reference to Fig. 5 to Fig. 8), in which the group of electrical components is held on the receiving device 15 for the application of the marking, the alignment direction 20 of the electrical components is aligned parallel to the axis of rotation 80. In order for the application of the marking by the device 10 to a high 20 marking quality, it is provided according to the invention that the length of the laser beam 35 between the laser head 30 and the electrical component to be marked accordingly isThe distance between the marking surface (not shown in the figures) of the correspondingly marking electrical component is kept as small as possible, and the distance 25 for all marking surfaces is adjusted accordingly. For this purpose, the movement device 40 has a lifting element 85 which is designed and configured for a lifting movement 90 (symbolized by a double arrow in Fig. 1) of the receiving device 15 relative to the laser head 30. This ensures that the receiving device or the electrical components arranged on it in the holding state 30 can be moved relative to or away from the laser head 30, and thus the distance between the receiving device 15 or the electrical components arranged on it and the laser head 30 can be changed or adjusted. As a result, the length of the laser beam 35 until it hits the aforementioned marking surfaces of the respective electrical components 35 can also be adjusted and, in particular, kept essentially the same length.For this purpose, the receiving device 15 to the laser head 30 BE2024 / 5919 -30- can be moved between a near and a far position by the lifting mechanism 85. In Fig. 5 1 it is evident that the lifting movement 90 is directed in a direction parallel to a radial direction of the axis of rotation 80. The device 10 provides that the lifting movement 90 is guided along a movement axis 95 directed towards the laser head (symbolized by a dashed line in Fig. 1). This option also enables the device 10 to mark 10 electrical components of different sizes with a desired marking quality by adjusting the distance of the relevant marking surface from the laser head 30 to set the focus position. This ensures that the distance of the laser head 30 to the marking surface, and thus the path of the laser beam 35, can be kept constant. Fig. 1 shows that the lifting movement 85 is guided in a straight line or linearly along the movement axis 95.Furthermore, it is provided that the motion device 40 is configured and designed such that it moves the lifting element 85 coupled, in particular synchronously, to the 20 motion guidance along the orbital motion path 55 of the laser head 30, in particular such that it moves the lifting element 85 in a motion path parallel to the orbital motion path 55 of the laser head 30. This advantageously achieves that the distance of the laser head 30 to a side surface of the respective electrical components or a side surface of the 25 receiving device 15 can be set and adapted accordingly. Thus, the device 10 is very flexible for use with electrical components of different sizes and can be adjusted accordingly to a marking surface on the respective electrical component. With reference to Fig. 5 to Fig.Figure 8 clarifies that the receiving device 15 is designed and configured for receiving a support rail on which the group of electrical components can be arranged or is arranged in a holding state. The movement device 40 has a second guide element 100, which is designed and configured such that the receiving device 15 is held rotationally fixed at least during the relative movement between the laser head (30) and the receiving device 35. BE2024 / 5919 -31- The movement device 40 also has a third guide element 105, which is designed and configured for translational movement guidance of the laser head 30, the translational movement guidance being directed parallel to the alignment direction 20 in which the electrical components are arranged in the holding state (see Figures 5 to 8). The control device 45 has a detection element 106 for optical detection 10 of a marking area 107, on which the laser beam 35 is directed for the application of the marking in an irradiation position.The detection device 106 is configured and designed such that, following optical detection of the marking area 107, an evaluation of actual marking parameters is carried out based on stored target marking parameters, whereby, in the event of a deviation from the marking parameters, the control device 45 controls the movement device 40 to adjust the irradiation position. Fig. 2A shows the device 10 from Fig. 1 in a first operating state, in which the laser head is arranged in a first position, in which the receiving device 20 15 is located in a position remote from the laser head 30. Fig. 2B shows the embodiment from Fig. 1 in a second operating state, in which the laser head 30 is arranged in a second position and has been moved along an orbital path around the receiving device 10. The receiving device 15 is held rotationally and orientably fixed by the second guide element 100, so that its orientation remains unchanged. Fig. 3A shows the device 10 from Fig. 2A in a second perspective view.Fig. 3B shows the embodiment from Fig. 2 in the second perspective view according to Fig. 3A. Fig. 4A shows the device 10 from Fig. 1 in the same perspective view, the illustration focusing on the receiving device 15 and the second guide element 100 for the receiving device 15, by means of which the receiving device 15 is held in a rotationally fixed orientation. Fig. 4B shows the device 10 from Fig. 4A in the same perspective view, the illustration focusing on the receiving device 15 for receiving a support, in particular a support rail (not shown in Fig. 4A / B). Metal support rails are known from the prior art, such that they can be held on the receiving device 15 by means of a magnetic force (e.g., due to the use of permanent magnets). In addition, it is possible to provide 10 mechanical holding means (not shown) by which the support rail is held on the receiving device 15. Fig. 5A shows the device 10 in the same view as in Fig.1 and in an operating state in which the group 110 of electrical components 115 (representing the others, one is designated with the reference numeral 115) is arranged on the 15 device 10 or, for the identification of which, the receiving device 15 is arranged in a position remote from the laser head 30, in this case a remote position from the laser head. This also clarifies a holding state in which the group 110 of electrical components 115 is arranged on the receiving device 15. The electrical components are arranged on a carrier 116, which 20 here forms a support rail 117, by being snapped onto the support rail. Fig. 5A illustrates that the receiving device 15 is configured and designed such that, in the holding state shown, in which the group 110 of the electrical components 115 is held on the receiving device 15 for the application of the 25 marking, the alignment direction 20 of the electrical components 115 is aligned parallel to the axis of rotation 80. Fig. 5B shows the embodiment of a device according to the invention from Fig.Fig. 5A shows the embodiment of a device according to the invention from Fig. 5A in the same perspective, wherein the group 110 of electrical components 115 are in a position in which they are approached by means of a lifting element 85 to the laser head 30. The group 110 of electrical components is thus in a close position to the laser head 30. Fig. 6 shows the embodiment of a device according to the invention from Fig. 5A in the same perspective, wherein the laser head is arranged to pivot about the axis of rotation to the receiving device as a result of a pivoting movement 35 about the axis of rotation.
