Description

[0001] Network-capable riveting tool

[0002] The present disclosure relates to a riveting device.

[0003] Riveting tools are typically used to create a riveted joint between two or more materials, such as sheet metal, at a junction where the materials lie against one another. To create the riveted joint, a plastically deformable, usually cylindrical connecting element, generally referred to as a rivet, is used. The rivet usually has a prefabricated setting head at one end. To create the riveted joint, the rivet is inserted into a connecting hole provided at the joint up to the setting head and then the other end of the rivet is plastically deformed into a closing head.

[0004] Riveting tools can also be used to add threads to thin-walled components. Rivet nuts or rivet bolts are used for this purpose, combining a rivet with a threaded element. The rivet nuts or rivet bolts are inserted into a pre-made rivet hole in the component, and then a portion of the rivet is plastically formed into a closing head.

[0005] Conventional riveting tools usually comprise a riveting tool which is designed to effect a plastic deformation which forms the closing head. To actuate the riveting tool, the riveting tools have a drive device which is often electromechanical and comprises, for example, an electric motor and a spindle gear designed as a ball screw drive. Such a riveting tool is described, for example, in EP 0 670 199 A1, which is referred to therein as a setting tool. The riveting tool is designed to set blind rivet nuts and is designed to subject the blind rivet nut to a compression which produces a closing head by exerting a pulling movement on a threaded rivet mandrel.

[0006] Riveting tools of the type discussed here allow rivets to be set quickly, which is useful when large quantities of fasteners have to be installed. The rivets themselves are comparatively light compared to other fasteners, which favors their use in weight-critical applications. This is one of the reasons why riveting tools are often found in industrial applications, such as the assembly of land vehicles and aircraft. In such applications, the riveting tools are subject to high continuous loads, as a large number of riveting operations are usually carried out in a relatively short space of time. However, this continuous load promotes signs of wear on the riveting tool, which can lead to device failure. These signs must therefore be detected at an early stage, particularly to avoid interruptions in the production chain.

[0007] Against this backdrop, there is a need to make riveting tools accessible for data monitoring. This is based on the expectation that data monitoring will enable early detection of wear on the riveting tool and / or early conclusions regarding any wear-related quality deterioration of the riveted joint. This is also based on the expectation that data monitoring will enable fundamental monitoring of the riveting tool, for example, to verify compliance with maintenance cycles.

[0008] In this regard, a riveting device is proposed which comprises a communication device, in particular an electrical communication device, for wirelessly communicating with an external interface and a control device, in particular an electrical control device, for controlling the communication device. This makes it possible for the riveting device to communicate with an external interface of an external unit via the communication device and in this way to set up a monitoring system. In order to enable wireless communication, a radio module, in particular an electrical radio module, is assigned to the communication device, for example, or the communication device has such a radio module, for example.

[0009] The term "control device" in the present disclosure is to be understood in particular as an electronic unit of computer hardware which controls certain processes and / or sequences with regard to the communication device. The control device can have a digital processing unit which, for example, comprises a microprocessor unit (CPU). The CPU can be data- and / or signal-connected to a memory system and / or bus system. The control device can have one or more programs or program modules. The digital processing unit can be designed such that commands which are implemented as a program stored in a memory system are processed, input signals are received from a data bus system and / or output signals are sent to a data bus system. A memory system can have one or more, in particular different, storage media.The storage media can in particular be optical, magnetic, solid-state storage media and / or other, preferably non-volatile storage media.

[0010] The term "communication device" in the present disclosure is to be understood in particular as an electronic unit of computer hardware which is suitable or designed for data transmission and / or data exchange with the external interface. The communication device can have a digital processing unit which, for example, comprises a microprocessor unit (CPU). The CPU can be data- and / or signal-connected to a memory system and / or bus system. The communication device can have one or more programs or program modules. The digital processing unit can be designed such that commands which are implemented as a program stored in a memory system are processed, input signals are received from a data bus system and / or output signals are sent to a data bus system.A storage system may comprise one or more, in particular different, storage media. The storage media may, in particular, be optical, magnetic, solid-state storage media and / or other, preferably non-volatile, storage media.

[0011] The proposed riveting device is based, for example, on a basic riveting device which comprises a riveting tool, a motor, in particular an electric motor, for actuating the riveting tool and preferably a motor control device, in particular an electric motor control device, for controlling the motor. Such a riveting device is described in more detail, for example, in the document EP 2 910 321 A1, to which reference is hereby made for the purpose of completing and supplementing the present disclosure, with the note that the document may assign a meaning to identical terms which differs from the present meaning. For example, the basic riveting device, in particular the riveting tool, is suitable for blind riveting, in which the riveting process is carried out from one side of a material to be provided with a blind rivet by means of a rivet mandrel.Instead of a blind rivet, a blind rivet nut or a blind rivet screw can also be used.

[0012] For example, the riveting tool comprises a mouthpiece and a mandrel holder movable relative to the mouthpiece along or in the direction of an effective axis. For example, the mandrel holder has a chuck housing movable relative to the mouthpiece along or in the direction of the effective axis and, for example, at least one clamping element, in particular a clamping jaw, movable in the chuck housing along a clamping path.

[0013] For example, the motor is a component of a drive device. For example, the drive device comprises at least one gear, such as a spindle gear, in particular a ball screw drive, which is interposed between the motor and the riveting tool, in particular the mandrel holder.

[0014] In the present disclosure, the term "motor control device" is to be understood in particular as an electronic unit of computer hardware which controls certain processes and / or sequences with respect to the motor. For example, the motor control device is configured to control the motor to execute a setting stroke. This can be triggered manually, for example by a switch.

[0015] The engine control device can have a digital processing unit which, for example, comprises a microprocessor unit (CPU). The CPU can be connected to a memory system and / or bus system for data and / or signals. The communication device can have one or more programs or program modules. The digital processing unit can be designed such that commands which are implemented as a program stored in a memory system are processed, input signals are received from a data bus system and / or output signals are sent to a data bus system. A memory system can have one or more, in particular different, storage media. The storage media can be in particular optical, magnetic, solid-state storage media and / or other, preferably non-volatile storage media.

[0016] In the proposed riveting device, the communication device is provided for communicating with the external interface in order to send data of the motor control device and / or other data of the riveting device and / or to receive data from the external interface.

[0017] Data sent by the communication device can contain information on the total number of setting operations carried out and / or information on the number of setting operations carried out since a reset and / or information on the fill level of a collecting container for residual mandrels and / or information on a tilted position of the riveting device and / or information on upcoming maintenance, such as oiling and / or changing the clamping jaws, and / or information on the charge level of any electrical energy storage device provided for supplying electrical energy to the motor and / or information on an applied setting force and / or information on the applied setting force in the event of a rivet mandrel breakage and / or information on a stroke traveled by the mandrel holder in the event of a rivet mandrel breakage.

[0018] Data received from the external interface may contain instructions for locking riveting operation and / or instructions for unlocking an existing locking of riveting operation and / or status information in response to requests from the riveting device. The data received from the external interface may also relate to firmware updates, for example, for the motor control device and / or the communication device and / or the control device.

[0019] It is advisable for communication between the proposed riveting device and the external interface to be carried out via a wireless network of the external interface. This is particularly advantageous if several or a large number of devices of the proposed riveting device are used, for example in a shared assembly hall. By using the wireless network of the external interface for communication, any interference with the wireless network, for example caused by signal interference from other networks within physical range, is counteracted, particularly if several or some of the riveting devices used share the wireless network of the external interface.Interference from other networks within physical range is minimized because only a few wireless networks are active or only the one wireless network of the external interface is active.

[0020] In order for the proposed riveting device to be able to use the wireless network of the external interface, it requires access. Therefore, according to one embodiment, the communication device is set up to be operated in a coupling mode in which a wireless network of the riveting device is activated in order to receive access data to the wireless network of the external interface. The communication device is therefore set up in particular to set up its own wireless network, which is used to receive the access data to the wireless network of the external interface. This makes it easier for a user to handle the riveting device in order to establish a coupling of the riveting device with the external interface. The user does not need to enter the access data on the riveting device.

[0021] The access data for the wireless network of the external interface can be an access key or can include an access key if the wireless network of the external interface is a closed wireless network. In the pairing mode of the communication device, it is then possible to obtain the access key to the closed wireless network of the external interface. This also makes handling the riveting device easier for the user, since the user does not need to know the access key.

[0022] The action to be carried out by the user can be reduced to causing the coupling mode to be activated. In this regard, the proposed riveting device can be provided with an actuating element, in particular a manual actuating element, and the control device is set up, for example, to control the communication device to activate the coupling mode when actuation of the actuating element is detected. It is advisable for the control device to be set up to control the communication device to deactivate the coupling mode when the access data for the wireless network of the external interface is available. This measure also makes it easier for the user to handle the riveting device in connection with setting up a communication connection with the external interface, since the user does not have to take any action to deactivate the coupling mode.This happens automatically through the control device.

[0023] It is also advisable for the control device to be configured to trigger the communication device to log into the wireless network of the external interface if the access data for the wireless network of the external interface is available and, in particular, if the pairing mode is deactivated. This counteracts any interference with the riveting device and / or the communication between the riveting device and the external interface that could be caused by unintentional access by third parties to the wireless network of the riveting device.

[0024] For example, another external interface located in physical proximity could attempt to connect to the riveting tool's wireless network, thereby causing an interference situation that would interrupt the riveting tool's workflow. Disabling the riveting tool's wireless network prevents such an interference situation. In particular, disabling pairing mode turns off or deactivates the riveting tool's wireless network early, preferably before the riveting tool connects to the external interface's wireless network.

[0025] In order to prevent unauthorized access by a third party to the wireless network of the proposed riveting device, the communication device has an enabling function which can be controlled by the control device. For example, in this regard, the control device is configured to control the communication device to enable access to the wireless network of the proposed riveting device when an access request is detected after activation of the coupling mode. Additionally or alternatively, the control device can be configured to control the communication device to enable access to the wireless network of the proposed riveting device when an access request is detected as the x-th access request after activation of the coupling mode, where x is an integer between 1 and 20 and where x can also be the integer 1 or the integer 20.

[0026] For example, the control device is configured to control the communication device to release access to the wireless network of the proposed riveting device if an access request is detected as the first access request after activation of the pairing mode. In this case, the integer counter x is equal to 1. This provides a further measure to prevent unauthorized access by a third party by allowing only a single participant to access the wireless network of the riveting device.

[0027] According to one embodiment, the wireless network of the proposed riveting device is a closed network. For example, in this case, the control device is configured to control the communication device to enable access to the wireless network of the proposed riveting device when an access request with a valid access key is detected after activation of the pairing mode. This also provides a measure to prevent unwanted access by a third party. Access to the wireless network of the proposed riveting device is only granted if an access key is present and this access key is suitable.

[0028] The proposed riveting device can be configured such that the wireless network of the riveting device is a local area network, in particular a local radio network (also referred to as WLAN). Furthermore, it is advisable for the wireless network of the proposed riveting device to be a WiFi network. This utilizes a common network technology, thus promoting a high degree of compatibility, allowing the proposed riveting device to be coupled with other external interfaces.

[0029] Furthermore, the proposed riveting device can be configured such that the communication device is configured to establish a socket connection with the external interface in coupling mode. For example, in this case, the control device is configured to control the communication device to establish the socket connection when a request to do so is detected and, in particular, when the coupling mode is activated.

[0030] According to a further aspect, a method for controlling the communication device of the riveting device described above is proposed. The advantages described above for the riveting device can be achieved by the proposed method. In one embodiment of the proposed method, the control device controls the communication device to deactivate the coupling mode when the access data for the wireless network of the external interface is available.

[0031] In a further or alternative embodiment of the proposed method, the communication device is controlled by means of the control device to log on to the wireless network of the external interface if the access data to the wireless network of the external interface are available and, in particular, the coupling mode is deactivated.

[0032] In particular, the control device controls the communication device to activate the coupling mode when actuation of the actuating element is detected. In particular, the control device controls the communication device to enable access to the wireless network of the riveting device when an access request is detected after activation of the coupling mode.

[0033] In particular, the control device is used to control the communication device to release access to the wireless network of the riveting device if an access request is detected as the x-th access request after activation of the pairing mode, where x is an integer between 1 and 20 and where x can also be the integer 1 or the integer 20. For example, the control device is used to control the communication device to release access to the wireless network of the riveting device if an access request is detected as the first access request after activation of the pairing mode. If the wireless network of the riveting device is a closed network, the control device can be used to control the communication device to release access to the wireless network of the riveting device if an access request with a valid access key is detected after activation of the pairing mode.The control device can also be used to control the communication device to establish a socket connection with the external interface if a request for this is detected and, in particular, if the coupling mode is activated.

[0034] According to a further aspect, a computer program product is proposed with a program code stored on a computer-readable medium for carrying out at least one embodiment of the method described above. For example, the control device of the riveting device described above contains the computer program product and / or the program code of the computer program product is implemented in the control device.

[0035] According to a further aspect, a control device for the riveting device described above is proposed, comprising the computer program product described above. The control device can be the control device described above.

[0036] According to a further aspect, an environment is proposed which comprises the riveting device described above and an external interface, such as the external interface described above. For example, the riveting device has the control device described above. For example, the external interface is configured to communicate with the communication device of the riveting device.

[0037] Further details and features will become apparent from the following description of at least one embodiment with reference to the drawing.

[0038] Fig. 1 shows an exemplary embodiment of a riveting device in a schematic sectional view, wherein the riveting device comprises a communication device for wireless communication with an external interface, and Fig. 2 shows possible sequences in the communication between the riveting device of Figure 1 and the external interface in a coupling mode and in a standby mode, shown in a flow diagram.

[0039] Figure 1 shows the structure of an exemplary embodiment of a riveting device 1. The exemplary riveting device 1 is suitable for attaching or setting rivets using the blind riveting method and is therefore designed for use with blind rivets.

[0040] The exemplary riveting device 1 comprises, for example, a riveting tool 10 and a drive device 20 for actuating the riveting tool 10. The riveting tool 10 is preferably assigned to a preferably elongated and / or tubular tool housing 3, in particular at least partially received therein. The drive device 20 is preferably assigned to a device housing 2, in particular received therein. The tool housing 3 is preferably supported on the device housing 2 and / or is held thereon. For example, the device housing 2 is a plastic housing. For example, the tool housing 3 is a metal housing.

[0041] The exemplary riveting tool 1 can be a hand-held riveting tool. The hand-held riveting tool 1 has, for example, a gripping surface 4.1, which can be at least partially formed on the tool housing 2. For example, the hand-held riveting tool 1 has a gripping part 4, which is at least partially formed by the tool housing 2. The gripping surface 4.1 or the gripping part 4 enables the exemplary riveting tool 1 to be held in the hand when it is applied to a workpiece to set a rivet, in particular a blind rivet. The riveting process as such then takes place by actuating the riveting tool 10 via the drive device 20.

[0042] The riveting tool 10 preferably has a mouthpiece 11 and a mandrel holder 12 movable relative to the mouthpiece 11 in the direction of an effective axis W or along the effective axis W. For example, the mandrel holder 12 has a chuck housing 13 and at least one, preferably several, clamping elements 14, 14', in particular clamping jaws, movable in the chuck housing 13 along a clamping path. Preferably, the mouthpiece 11 and / or the mandrel holder 12 and / or the chuck housing 13 and / or the clamping elements 14, 14' are a metal part.

[0043] The mouthpiece 11 serves, for example, to receive a rivet (not shown in Figure 1) to be set, in particular a blind rivet, and preferably has a through-hole 11.1 for inserting the rivet mandrel of the rivet therein. The mouthpiece 11 also serves, in particular, for positioning on a workpiece to be provided with the rivet. Preferably, the mouthpiece 11 is fastened to the tool housing 3, for example, screwed thereto. For example, the mouthpiece 11 is fastened to one end of the tool housing 3 and the opposite end faces the device housing 2.

[0044] The mandrel holder 12 serves, for example, to fix the rivet mandrel, so that a displacement-resistant connection is created between the received rivet mandrel and the mandrel holder 12. This can be done, for example, via the chuck housing 13 with the clamping elements 14, 14' movably arranged therein, by which the rivet mandrel is fixed, in particular clamped, in the chuck housing 13.

[0045] The drive device 20 comprises at least one motor 21. The motor 21 is preferably a rotary motor which, for example, has a rotatable output shaft 21. 1. The motor 21 can be an electric motor. In this case, a preferably replaceable and preferably rechargeable electrical energy store, such as an accumulator 7, can be provided to supply electrical energy to the motor 21. In this respect, the exemplary riveting tool 1 can be a battery-powered tool. For example, the electrical energy store is arranged in the region of an end of the handle part 4 facing away from the riveting tool 10.

[0046] The drive device 20 comprises, for example, a spindle gear 22 which can be driven by the motor 21. The spindle gear 22 is preferably designed to convert a rotary drive movement emanating from the output shaft 21.1 into a translatory drive movement acting along the effective axis W for actuating the riveting tool 10 or the mandrel holder 12. The spindle gear 22 can be a ball screw drive. In the exemplary riveting tool 1, at least one, for example two, reduction stages 24, 25 are preferably interposed between the motor 21 and the spindle gear 22. For example, the reduction stages 24, 25 have a first gear element 24.1 or 25.1 and a second gear element 24.2 or 25.2. For example, the reduction stages 24, 25 are connected one behind the other in the power flow. For example, the reduction stages 24, 25 use a common intermediate shaft 26.For example, the intermediate shaft 26 is rotatably mounted in the radial direction via at least one, preferably two bearings 27, 27' in the device housing 2. For example, at least one of the reduction stages 24, 25 is a spur gear stage, and the associated gear elements 24.1, 24.2, 25.1, 25.2 are spur gears.

[0047] The drive device 20 can actuate the riveting tool 10 such that the mandrel holder 12 or the chuck housing 13 with the rivet mandrel fixed therein is moved away from the mouthpiece 11 in the direction of the effective axis W. This occurs, for example, in that the drive device 20 pulls the mandrel holder 12 or the chuck housing 13 away from the mouthpiece 11. This known mode of operation and the blind riveting that can be carried out with it are described in more detail in the document EP 0 116 954 A2, to which reference is hereby made for the purpose of completing and supplementing the present disclosure, with the note that the document may assign a meaning to identical terms that differs from the present meaning.

[0048] The spindle gear 22 is preferably arranged in the device housing 2. The spindle gear 22 preferably comprises a threaded spindle 22.1 and a spindle nut 22.2. The threaded spindle 22.1 preferably has a front end facing the mandrel holder 12, in particular the chuck housing 13, and an opposite rear end. The threaded spindle 22.1 and the spindle nut 22.2 are preferably arranged concentrically to one another with respect to a gear axis. The spindle axis of the threaded spindle 22.1 preferably lies on the gear axis. The output shaft 21.1 of the motor 21 is preferably arranged axially parallel to the gear axis. The gear axis or the spindle axis preferably lies on the effective axis W. For example, the threaded spindle 22.1 and the spindle nut 22.2 are designed such that the spindle nut 22.2 drives the spindle driven by the motor 21 or drivable gear element and the threaded spindle 22 .1 is used to carry out the translational drive movement in order to actuate the riveting tool 10. For example, the threaded spindle 22. 1 is connected at its front end directly or indirectly, for example via an intermediate piece, to the mandrel holder 12 or the chuck housing 13 in a displacement-proof manner. For example, the spindle nut 22. 2 is furthermore rotatably mounted in the device housing 2 in the radial direction with respect to the gear axis or the effective axis W via at least one, preferably two radial bearings 23, 23'. In the exemplary riveting device 1, for example, a torque arm (not shown in Figure 1) is provided in order to secure the threaded spindle 22. 1 against rotation relative to the device housing 2.

[0049] The threaded spindle 22.1 is preferably designed as a hollow spindle with a passage 28 running in the direction of its longitudinal extent. The passage 28 makes it possible to remove a remainder of a rivet mandrel remaining from a riveting process from the riveting tool 10. For example, the passage 28 opens at the rear end of the threaded spindle 22.1 into a tubular element 5, which in turn opens into a collecting container 6. For example, a mandrel disposal path is realized in this way via the threaded spindle 22.1, wherein the collecting container 6 can serve as a collector for mandrel residues. The tubular element 5 and the collecting container 6 are only indicated by way of example and are shown incompletely in Figure 1.

[0050] The exemplary riveting device 1 has, for example, a motor control device 30, in particular an electronic motor control device, which is signal-connected to the motor 21 via at least one first line 71 and serves to control the motor 21. The motor control device 30 is preferably accommodated in the device housing 2. The motor control device 30 can be signal-connected to a switch (not shown in Figure 1). This enables, for example, the motor control device 30 to start a setting process when actuation of the switch is detected. Further details on the functioning of the motor control device 30 and its possible functions are described in more detail, for example, in the document EP 2 910 321 A1, to which reference is already made.The exemplary riveting device 1 has, for example, a communication device 40, in particular an electronic communication device, which is suitable for wireless communication with an external interface (not shown in Figure 1). For example, the communication device 40 is accommodated in the device housing 2. The communication device 40 is set up, for example, to wirelessly transmit data from the motor control device 30 and / or other data from the exemplary riveting device 1 to the external interface. For this purpose, the communication device 40 is, for example, signal-connected to the motor control device 30 via at least one second line 72. The communication device 40 can also be signal-connected to a detection device or sensor system, if present (not shown in Figure 1), of the exemplary riveting device 1.

[0051] The data to be transmitted can contain information on the total number of setting operations carried out and / or information on the number of setting operations carried out, for example since a reset and / or information on the fill level of the collecting container 6 and / or information on a tilted position of the exemplary riveting device 1 and / or information on upcoming maintenance, such as oiling and / or changing the clamping elements 14, 14', and / or information on the charge state of a possibly provided electrical energy storage device 7 for supplying electrical energy to the motor 21 and / or information on an applied setting force and / or information on the applied setting force in the event of a rivet mandrel breakage and / or information on a stroke traveled by the mandrel holder 12 in the event of a rivet mandrel breakage.

[0052] The exemplary riveting device 1 has, for example, a control device 50 for controlling the communication device 40. For example, the control device 50 is housed in the device housing 2. For example, the control device 50 is signal-connected to the communication device 40 via at least one third line 73. For example, the control device 50 is configured to control the communication device 40 to deactivate the coupling mode when the access data for the wireless network of the external interface are present.

[0053] In the exemplary riveting device 1, the communication device 40 is also configured, for example, to receive data from the external interface. The data to be received can contain instructions, for example, for the motor control device 30. These can be instructions for blocking the riveting operation of the exemplary riveting device 1 and / or instructions for unlocking an existing block on the riveting operation. Additionally or alternatively, the data to be received can relate to software, such as firmware updates, in particular for the motor control device 30 and / or the communication device 40 and / or the control device 50. Additionally or alternatively, the data to be received can contain information on the status of requests from the exemplary riveting device 1.

[0054] For wireless communication with the external interface, the communication device 40 has, for example, a radio module 41. Preferably, the radio module 41 is configured to communicate with the external interface via a wireless network of the external interface. The wireless network of the external interface can be a local area network, such as a Wi-Fi network.

[0055] In the exemplary riveting device 1, the radio module 41 or the communication device 40 is also configured, in particular, to establish a wireless network itself. The wireless network of the exemplary riveting device 1 can be a local network, such as a WiFi network. Preferably, the communication device 40 is configured to receive access data to the wireless network of the external interface via its own wireless network. For this purpose, the communication device 40 can be operated in a coupling mode in which the own wireless network of the exemplary riveting device 1 is activated.

[0056] For example, the exemplary riveting tool 1 has an actuating element 60, in particular a manual actuating element 60. For example, the actuating element 60 is assigned to the tool housing 2, in particular arranged thereon. For example, the control device 50 is signal-connected to the actuating element 60 via at least one fourth line 74 and is configured, for example, to control the communication device 40 to activate the coupling mode when actuation of the actuating element 60 is detected. For example, the control device 50 is configured to control the communication device 40 to release access to its own wireless network when an access request from the external interface is detected as the first access request after activation of the coupling mode.For example, the control device 50 is further configured to control the communication device 40 to log in to the wireless network of the external interface when the access data to the wireless network of the external interface are available and the pairing mode is deactivated.

[0057] In addition, the control device 50 can be signal-connected to the motor control device 30, for example via at least one further line (not shown in Figure 1). In this case, the control device 50 can be set up to control the motor control device 30 to block operation of the motor 6 if activation of the coupling mode is detected. The control device 50 can also be set up to control the motor control device 30 to unlock this block if deactivation of the coupling mode is detected. This counteracts the situation in which the exemplary riveting device 1 carries out setting processes while data is not yet being exchanged between the exemplary riveting device 1 and the external interface. In this respect, a measure is taken to be able to carry out continuous data monitoring with regard to the exemplary riveting device 1.

[0058] In the exemplary riveting device 1, the communication device 40 is configured, in particular, to establish a socket connection with the external interface in coupling mode. Accordingly, the control device 50 is configured, for example, to control the communication device 40 to establish the socket connection when a request for this is detected and the coupling mode is activated.

[0059] In the exemplary riveting device 1, it can be provided that the device's own wireless network is a closed network, and the communication device 40 or the radio module 41 is configured accordingly. In this case, the control device 50 is configured, for example, to control the communication device 40 to enable access to the device's own wireless network when an access request coming from the external interface with a valid access key is detected after activation of the coupling mode.

[0060] The wireless network of the external interface can also be a closed network. In this case, the access data to be requested by the exemplary riveting device 1 then concerns, for example, an access key or includes an access key to the wireless network of the external interface.

[0061] Figure 2 shows an example of the communication between the exemplary riveting device 1 and the external interface in the coupling mode of the exemplary riveting device 1 and in a subsequent standby mode, wherein for the sake of simplicity only the initial phase of the standby mode is shown. In Figure 2, the external interface is shown as an example and provided with the reference symbol 100. For the purpose of illustration, the exemplary riveting device 1 and the external interface 100 are shown side by side and a possible communication between the exemplary riveting device 1 and the external interface 100 is schematically indicated along a shown time axis t. The time period for the coupling mode is marked A and the initial phase of the time period for the standby mode is marked B.

[0062] The wireless network of the external interface 100 is provided with the reference symbol NI, for example. The wireless network NI can be a closed network, as described above. The wireless network NI is preferably continuously active, for example, during the period of coupling mode A and during the period of standby mode B. In a temporal view along the time axis t, the following communication, illustrated by various arrows S1 to S14, can take place between the external interface 100 and the exemplary riveting device 1:

[0063] The wireless network NI of the external interface 100 scans the network environment for possible other networks, which is illustrated by the arrow S1. In the exemplary riveting device 1, the actuating element 60 is actuated manually, for example, and the communication device 40 is then controlled by the control device 50 to activate the coupling mode, whereupon the exemplary riveting device 1 activates its own wireless network, which is designated by the reference symbol N2 in Figure 2.

[0064] The wireless network NI of the external interface 100 finds the activated wireless network N2 of the exemplary riveting device 1. For example, the external interface 100 provides a user P with information about this, for example acoustically and / or visually and / or haptically. The user P then selects the exemplary riveting device 1 as a communication partner, which is illustrated by the arrow S2. If the wireless network N2 of the exemplary riveting device 1 is a closed network, it is provided, for example, that the user P specifies or enters an access password K2 to the exemplary riveting device 1 at the external interface 100, which is illustrated by the arrow S3.

[0065] The external interface 100 then initiates an access request to the exemplary riveting device 1 according to the arrow S4. The exemplary riveting device 1 recognizes the access request from the external interface 100, and the control device 50 controls the communication device 40 to release access to its wireless network N2. Before the release, a check may have taken place to determine whether the access request is, for example, a first access request after activation of the pairing mode. Before the release, a check may also have taken place to determine whether the access password K2 is valid. If the exemplary riveting device 1 has released access to its wireless network N2, the external interface 100 is informed thereof, which is illustrated by the arrow S5.

[0066] Subsequently, the external interface 100 initiates a request to establish a socket connection to the exemplary riveting device 1 according to arrow S6. The exemplary riveting device 1 recognizes the request, and the control device 50 controls the communication device 40 to establish the socket connection. The exemplary riveting device 1 then informs the external interface 100 according to arrow S7 that the establishment of the socket connection has been accepted.

[0067] The external interface 100 then sends its access data Kl to the exemplary riveting device 1, as illustrated by the arrow S8. The exemplary riveting device 1 then informs the external interface 100 about the receipt of the access data Kl according to the arrow S9. The exemplary riveting device 1 preferably stores the received access data Kl (arrow S10). Subsequently, the communication device 40 is controlled by the control device 50 to deactivate the coupling mode, whereupon the coupling mode is deactivated.

[0068] By deactivating the pairing mode, the wireless network N2 of the exemplary riveting device 1 is now switched off. The exemplary riveting device 1 now logs into the wireless network NI of the external interface 100, for example, using the received access data K1 (arrow S11). The external interface 100 then grants the exemplary riveting device 1 access to the wireless network NI and informs the exemplary riveting device 1 of this via its communication device 40, as illustrated by the arrow S12.

[0069] The exemplary riveting device 1 then initiates a request to establish a socket connection to the external interface 100 via its communication device 40, as indicated by arrow S13. The external interface 100 recognizes the request, enables the establishment of the socket connection, and informs the exemplary riveting device 1 that the establishment of the socket connection has been accepted (arrow S14). The desired communication connection between the exemplary riveting device 1 and the external interface 100 is now established. Data from the exemplary riveting device 1 can now be sent to the external interface 100, or data can be received from the external interface 100.
