By means of a crimping tool can be done by manual operation of hand levers pressing or crimping a workpiece. Here, a crimping tool is used in particular to produce a permanent mechanical connection and electrical contacting. This is preferably done by crimping a plug with a cable or an electrical conductor of any type. Depending on the profile of the dies used, different crimping processes can be carried out with the crimping tool. For example, it may be a closed crimp in which the conductor is inserted into a closed crimping zone of a plug or into a closed sleeve and crimped by plastic deformation of the crimping zone or sleeve. But it is also possible that an open crimp is generated, in which the plug has an open crimping zone, in which the conductor can be inserted from above.

u. ä.

• der Umgebung der Crimpzange,
• eines mit der Crimpzange zu bearbeitenden Werkstücks oder eines Teils desselben,
• des Benutzers der Crimpzange und/oder
• des in der Crimpzange verwendeten Gesenks

erfolgen. Um lediglich einige nicht beschränkende Beispiele zu nennen, kann die Crimpzange von dem Benutzer in eine nicht einsehbare Umgebung oder nur durch eine kleine Öffnung zugänglichen Raum eingeführt werden und mittels der Kamera (und einer etwaigen durch die Crimpzange bereitgestellten Beleuchtung) und der dadurch erzeugten Aufnahme, die dann vorzugsweise außerhalb der Kamera für den Benutzer angezeigt wird, kann dann ein Kabel gesucht werden, welches mit der Crimpzange in der Umgebung oder in dem Raum vercrimpt werden soll. Möglich ist beispielsweise auch, dass mittels der Kamera eine Überwachung oder eine Dokumentation des Einführens eines Kabels in einen Stecker und/oder des mit Kabel und Stecker gebildeten Werkstücks in eine von Gesenken der Crimpzange gebildete Aufnahme überwacht und/oder dokumentiert wird. Möglich ist des Weiteren auch, dass mit der Kamera vor, während oder nach dem Durchlaufen eines Crimpprozesses eine Aufnahme des Werkstücks erzeugt wird, die dann zwecks Dokumentation gespeichert wird oder auf Grundlage welcher dann eine automatisierte Prüfung erfolgt, ob der Crimpprozess ordnungsgemäß durchlaufen ist, was insbesondere auf Grundlage einer automatischen Bilderkennung erfolgen kann. Möglich ist beispielsweise des Weiteren, dass mit der Kamera vor dem Durchlaufen des Crimpprozesses eine Aufnahme des Werkstücks erzeugt wird, aus welcher dann (insbesondere auf Grundlage einer automatischen Bilderkennung) eine Geometrie des Werkstücks ermittelt wird, um einen Zustand oder Typ des Werkstücks zu ermitteln. Möglich ist auch, dass in dieser Weise eine (sich u. U. verändernde) Geometrie des Werkstücks während oder nach des Vercrimpens ermittelt wird.By means of the camera of the crimping tool can in particular a recording

• the environment of the crimping tool,
• a workpiece to be machined with the crimping tool or a part thereof,
• the user of the crimping tool and / or
• of the die used in the crimping tool

respectively. To cite but a few non-limiting examples, the crimping tool may be inserted by the user into an unobservable environment or space accessible only through a small opening, and by the camera (and any illumination provided by the crimping tool) and the shot produced thereby, which is then preferably displayed outside the camera for the user, then a cable can be searched, which is to be crimped with the crimping tool in the environment or in the room. It is also possible, for example, to monitor and / or document a monitoring or documentation of the insertion of a cable into a plug and / or the workpiece formed with cable and plug into a receptacle formed by dies of the crimping tool. Furthermore, it is also possible that with the camera before, during or after passing through a crimping process a recording of the workpiece is generated, which is then stored for documentation or on the basis of which an automated check is made, if the crimping process is properly completed, which in particular based on automatic image recognition. It is furthermore possible, for example, for the camera to be used to record the workpiece before it passes through the crimping process, from which a geometry of the workpiece is then determined (in particular based on automatic image recognition) in order to determine a state or type of the workpiece. It is also possible that in this way a (possibly changing) geometry of the workpiece during or after crimping is determined.

It is also important in the crimping process with a crimping tool to ensure that a workpiece has a defined position and orientation with respect to the receptacle formed by the dies. It is possible within the scope of the invention for the camera (before, during or after passing through the crimping process) to produce a receptacle from which the position and / or orientation of the workpiece relative to the receptacle can be determined.

In principle, the camera can be arranged in any area of the crimping tool, wherein the camera can be an integral part of the crimping tool or can be detachable from it, whereby the camera is simply connected to the crimping tool as needed and thus inserted. It is possible, for example, that the camera (possibly together with an electronic control unit and / or an associated battery) forms a module which via a magnetic connection, a snap-in connection, a lock, a screw, a bond u. Ä. Can be attached to a pliers head of the crimping tool, the aforementioned module can then be supplied and used as an additional module to a conventional crimping tool. The recording of the camera can be processed by the control unit of the module, the result generated by the processing or the recording itself can be transmitted via a provided with the connection of the module with the pliers head electrical connection to a control unit of the electronic unit of the crimping tool or wirelessly the control unit of the crimping tool or an external control unit are transmitted.

Preferably, the camera is arranged in the region of a pliers head. This arrangement has the advantage, for example, that the camera is arranged adjacent to the dies and the receptacle formed by them and / or is able to detect the immediate vicinity of the pliers head.

In principle, it is possible that the position and / or orientation of the camera in the crimping tool is fixed. For a particular proposal of the invention, the position and / or orientation of the camera can be changed, wherein by means of a change, a change of the object of the recording generated with the camera can be made possible. Here, the change in the position and / or orientation of the camera can be done with multiple discrete positions or this is done continuously. It is possible, for example, that the camera is arranged in a pivot bearing, whereby the orientation of the camera is changeable. To mention just a few more non-limiting examples, the camera may be held on a pivotable, deployable or telescopable arm or cantilever, or on a multi-stable, flexible arm.

For a further proposal of the invention, the camera is used in connection with a special structural design of the crimping tool. In this case, the crimping tool has a mechanical pliers part. The mechanical pliers part has two pivotable relative to each other, manually operated by the user hand lever (wherein the mechanical pliers part may also have a third hand lever, as this subject of the non-prepublished patent application EP 18 190 465.7 is). Furthermore, the mechanical pliers part has two relatively movable pliers jaws. The jaws are so via any drive mechanism (for example, a toggle lever drive) coupled with the hand levers that can be moved via a pivoting stroke of the hand lever, the jaws on a Crimphub. The drive mechanism may have any gear ratio. The use of the invention is not limited to a specific drive mechanism with respect to the specific embodiment of the mechanical pliers part. To name just a few non-limiting examples of the invention, the drive mechanism according to the not pre-published European patent application EP 18 166 739.5 or according to the pamphlets DE 10 2008 005 472 B3 . DE 4 023 337 C1 . DE 40 26 332 C2 . DE 19 713 580 C2 . DE 19 753 436 C2 . DE 19 807 737 C2 . DE 10 2005 003 615 B3 . DE 20 2008 003 703 U1 be formed, in which case the degrees of freedom of the jaws can be designed according to these embodiments and the arrangement of the jaws and hand lever can be done relative to each other and viewed in the case of the formation of the crimping tool as a multi-mandrel crimping tool as a "jaw" also relatively twisted actuation rings or actuation discs can be. Furthermore, for this proposal of the invention, the forceps jaws can be moved translationally over the crimping stroke (cf., for example, the crimping pliers CS 30, CS 10, CSV 10 of the Applicant) or pivoted (cf., for example, the crimping pliers CK 100 of the Applicant). For this proposal of the invention, an electronics assembly is present. The electronics assembly is disposed in a pliers head portion of the mechanical pliers portion disposed between the hand levers and the pliers jaws.

For this embodiment, the invention proposes that the electronic assembly is formed independently of the mechanical pliers part. This means that the mechanical function of the crimping tool can also be provided if the electronics assembly is or is not present. This has the consequence, for example, that it is possible that the crimping tool can be produced in two variants, wherein one variant of the crimping tool is equipped without electronic assembly, while the other variant is equipped with electronic assembly. For both variants then the same mechanical pliers part can be used or this is only slightly adapted to the variants. Under certain circumstances, the formation of the electronic assembly separately from the mechanical pliers part also leads to a simplification of the production and / or assembly, since the mechanical pliers part on the one hand and the electronics module can be manufactured at different manufacturing sites and possibly pre-assembled and / or different Materials can be made. Furthermore, the invention proposes that an arrangement of the electronic component takes place in a special area of the crimping tool. According to the invention, the electronic component is arranged in a pliers head part of the mechanical pliers part. This pliers head part is the part of the pliers head, which is arranged between the hand levers and the jaws. In the region of this pliers head part may be at least a part of the drive mechanism with drive elements such as a toggle lever drive. If the pliers head part has a housing or cover plates, the housing or the cover plates are suitable for fastening the electronics module to the pliers head part and thus to the crimping tool.

This embodiment thus utilizes the already existing pliers head part, which results in a compact design of the crimping tool. In the context of the invention, the electronic assembly is attached directly to the pliers head part, which u by any solvable or unsolvable mounting options, in particular screwing, welding, gluing, latching and / or locking u. Ä., Can be done.

With regard to exemplary possibilities of the design of the electronic module whose electrical or electronic connection with other components of the crimping tool or the environment, the guaranteed with the electronic unit functions and the structural or electrical design of the electronic module and connection possibilities of the same with the mechanical pliers part to the non-prepublished European patent application EP 18 173 803.0-1019 which is the subject of the present patent application.

According to the invention, the camera is also part of the electronic component. In particular, the camera is integrated in a housing of the electronic module, wherein then an opening of a housing of the electronic module or a transparent portion of the electronic module, the generation of a recording of an environment of the electronic module can take place.

For the type of triggering a recording of the camera, there are many possibilities within the scope of the invention. Thus, the recording can be done by the operation of a manual release by the user, with such a trigger preferably in the range of a hand lever or is arranged in one of a hand lever easily accessible with a finger portion of the pliers head. It is also possible that the recording can be triggered automatically by a control unit, which, for example, by reaching a condition for the amount and / or the course of a crimping force and / or a Crimpwegs (in particular a threshold value of the crimping force and / or Crimpweges) can.

For a particular proposal of the invention, a triggering of the camera takes place by a movement of a hand lever or a component driven therefrom, for example a component of the drive mechanism or a jaw. For this purpose, a switch actuated by the movement can be present which triggers the recording, or a sensor can detect the movement and carry out an evaluation by the control unit. For example, this can be triggered the recording of the camera at the beginning of the movement of a hand lever, so with the commissioning of the crimping tool. It is also possible that the receptacle is triggered for the achievement of any Crimpwegs the hand lever or a component driven therefrom, and this can also be done preferably with the achievement of the closed position.

For a further proposal of the invention, the crimping tool has a sensor. By means of the sensor, the crimping force (or a force correlating therewith in the drive mechanism) is detected. In this case, a recording of the camera in response to the crimping force can be triggered, for example, if the course and / or the amount of the crimping force meets an evaluation criterion. To mention only a simple example which does not limit the invention, the camera can be triggered when the crimping force exceeds a threshold value.

The crimping tool equipped with the camera can only be operated "partially" or partially. In this case, the image of the camera can be displayed on a suitable output of the crimping tool, or information or test results generated by means of an image recognition from the image can be displayed on a display of the crimping tool. It is also possible that only by means of a control unit recording, for example, for monitoring, is evaluated and the control unit interrupts the Crimphub upon detection of an evaluation or error criterion, locks the crimping tool or, for example by means of a warning light or LED indicates whether the crimping process has passed properly or not.

For a particular proposal of the invention, however, the crimping tool has an interface. Control logic is then present in a control unit of the crimping tool. By means of the control logic and the interface can then transfer from the crimping tool to external devices such as a smartphone, a PC, via the Internet u. Ä.

For a suggestion in this case a transmission of the recording takes place itself by the crimping tool.

• einen auf Grundlage der Aufnahme erkannten Typ des Werkstücks und/oder
• einen auf Grundlage der Aufnahme oder über eine Erfassungseinrichtung erkannten Typ eines Gesenks, mit welchem die Crimpzange ausgestattet ist und mittels dessen der Crimpprozess durchgeführt wird und/oder
• eine Spezifikation des Benutzers der Crimpzange und/oder
• ein Datum und/oder eine Uhrzeit der Durchführung des Crimpprozesses und/oder
• ein Crimpkraftsignal und/oder
• ein Crimpwegsignal.

Alternatively or additionally, process data can be transmitted from the crimping tool via the interface. These are for example

• a recognized on the basis of the recording type of workpiece and / or
• a type of a die recognized on the basis of the receptacle or via a detection device, with which the crimping tool is equipped and by means of which the crimping process is carried out and / or
• a specification of the user of the crimping tool and / or
• a date and / or time of performing the crimping process and / or
• a crimp force signal and / or
• a crimp signal.

The information thus transmitted from the interface can be stored in the external device for documentation or further analyzed and evaluated here.

It is also possible that the result of an evaluation made by a control unit of the crimping tool can be transmitted from the crimping tool to the external device via the interface.

For the aforementioned examples, the interface is thus responsible for a transmission of information from the crimping tool to the external device.

• Hierbei kann es sich beispielsweise um eine Soll-Aufnahme handeln. Die Soll-Aufnahme ist dabei für ein spezifisches Werkstück, welches mit der Crimpzange vercrimpt werden soll, und/oder ein spezifisches Gesenk, welches während des Crimpprozesses Einsatz findet, spezifisch. Eine Beurteilung eines Crimpprozesses kann dann durch eine Steuereinheit der Crimpzange dadurch erfolgen, dass die vor, während oder nach dem Crimpprozess von der Kamera der Crimpzange erzeugte Aufnahme verglichen wird mit der Soll-Aufnahme. Stimmt die Aufnahme (innerhalb vorgegebener Toleranzschwellen) mit der Soll-Aufnahme überein, kann hieraus geschlossen werden, dass der Crimpprozess ordnungsgemäß durchlaufen ist - andernfalls liegt ein nicht ordnungsgemäßer Crimpprozess vor. Möglich ist aber alternativ oder kumulativ auch, dass auf Grundlage eines Vergleichs der Aufnahme mit der Soll-Aufnahme geprüft wird, ob das Werkstück in richtiger Position und/oder Orientierung in die Gesenkaufnahme eingelegt worden ist. Alternativ oder kumulativ möglich ist, dass anhand eines Vergleichs einer Aufnahme des Werkstücks und/oder eines Gesenk (insbesondere bei Erzeugung der Aufnahme in in die Crimpzange eingelegtem Zustand des Werkstücks und/oder des Gesenks oder bei einem Halten des Werkstücks und/oder des Gesenks im Aufnahmebereich der Kamera bspw. vor oder neben dem Crimpkopf) mit der Soll-Aufnahme der Typ des Gesenk und/oder der Typ des Werkstücks identifiziert wird und/oder geprüft wird, ob eine zulässige Kombination eines Typs eines Werkstücks mit einem Typ eines Gesenks vorliegt.
• Anstelle der Übertragung einer Soll-Aufnahme und des Vergleichs der Soll-Aufnahme mit der Aufnahme können auch charakteristische Größen der Soll-Aufnahme übertragen werden, die dann verglichen werden mit entsprechenden charakteristischen Größen, die mittels einer automatischen Bildverarbeitung aus der von der Kamera erzeugten Aufnahme erzeugt werden.
• Ebenfalls möglich ist, dass ein Auswertekriterium, insbesondere ein Soll-Crimpkraftverlauf und/oder ein Soll-Crimpwegverlauf, Toleranzschwellen derselben, ein Auslöseweg und/oder eine Auslösekraft für das Auslösen einer Aufnahme mit der Kamera über die Schnittstelle an die Crimpzange übertragen werden. Hierbei ist das Auswertekriterium insbesondere spezifisch für ein spezifisches Werkstück, welches mit der Crimpzange vercrimpt werden soll, und/oder ein spezifisches Gesenk, welches während des Crimpprozesses Einsatz findet.

Alternatively or additionally, a transmission from an external device via the interface to the crimping tool.

• This may be, for example, a nominal recording. The target receptacle is for a specific workpiece, which is to be crimped with the crimping tool, and / or a specific die, which is used during the crimping process finds, specifically. An assessment of a crimping process can then be carried out by a control unit of the crimping tool by comparing the recording produced before, during or after the crimping process by the camera of the crimping tool with the setpoint acquisition. If the recording agrees (within predefined tolerance thresholds) with the target recording, it can be concluded from this that the crimping process has been carried out correctly - otherwise there is an incorrect crimping process. Alternatively or cumulatively, however, it is also possible to check whether the workpiece has been inserted in the correct position and / or orientation into the die receptacle on the basis of a comparison of the receptacle with the desired receptacle. Alternatively or cumulatively, it is possible that by comparison of a receptacle of the workpiece and / or a die (in particular when the receptacle is inserted in the crimping tool in the state of the workpiece and / or the die or when holding the workpiece and / or the die in Receiving area of the camera, for example, in front of or next to the crimping head) is identified with the target recording the type of die and / or the type of workpiece and / or checked whether there is an allowable combination of a type of workpiece with a type of die.
• Instead of transmitting a nominal image and comparing the nominal image with the image, it is also possible to transmit characteristic quantities of the nominal image, which are then compared with corresponding characteristic quantities which are generated from the image produced by the camera by means of automatic image processing become.
• It is also possible that an evaluation criterion, in particular a desired crimp force profile and / or a desired Crimpwegverlauf, tolerance thresholds thereof, a triggering path and / or a triggering force for triggering a recording with the camera are transmitted via the interface to the crimping tool. In this case, the evaluation criterion is in particular specific for a specific workpiece which is to be crimped with the crimping tool, and / or a specific die which is used during the crimping process.

• Diese Auswertung kann darin bestehen, dass eine Ermittlung eines Typs eines Werkstücks erfolgt. Möglich ist beispielsweise, dass die Crimpzange von dem Benutzer so ausgerichtet wird, dass die Kamera der Crimpzange eine Aufnahme des Werkstücks erzeugt. Auf Grundlage einer automatischen Bilderkennung, die durch die Steuerlogik gewährleistet wird, wird dann der Typ des Werkstücks ermittelt. Dies kann durch Auswertung charakteristischer Punkte des Werkstücks oder der Außengeometrie des Werkstücks erfolgen, um lediglich einige die Erfindung nicht beschränkende Beispiele zu nennen.
• Alternativ oder zusätzlich möglich ist, dass die Kamera eine Aufnahme des in der Crimpzange eingesetzten Gesenks erzeugt. Auf Grundlage der Aufnahme ermittelt dann die Steuerlogik einen Typ des Gesenks. Möglich ist beispielsweise, dass die Aufnahme einen Barcode erfasst, wobei in diesem Fall die Kamera auch als Scanner des Barcodes ausgebildet sein kann. Entsprechend kann auch die Aufnahme einen QR-Code erfassen. Möglich ist, dass die Aufnahme eine anderweitige Kennzeichnung des Gesenks erfasst, insbesondere eine Ziffernfolge. Schließlich ist möglich, dass die Aufnahme die Geometrie des Gesenks erfasst.
• Möglich ist alternativ oder kumulativ, dass auf Grundlage der von der Kamera aufgenommenen Aufnahme eine Dokumentation des Crimpprozesses erfolgt, wobei die Dokumentation darin bestehen kann, dass ein oder mehrere Bilder der Aufnahmen, ggf. an charakteristischen Prozesspunkten des Crimpprozesses, dokumentiert werden, indem eine Speicherung erfolgt. Hierbei kann die Speicherung in einem Speicher der Crimpzange erfolgen oder nach Übertragung über die vorgenannte Schnittstelle über das externe Gerät.
• Möglich ist auch, dass auf Grundlage der von der Kamera aufgenommenen Aufnahme eine Bewertung des Ergebnisses des Crimpprozesses erfolgt.
• Schließlich ist auch möglich, dass mittels der Aufnahme der Crimpzange eine Ermittlung der Position und/oder Orientierung des Werkstücks relativ zu einer Aufnahme der Crimpzange erfolgt. Dies kann während oder nach dem Durchlaufen des Crimpprozesses der Fall sein. Vorzugsweise erfolgt dies aber bereits vor Beginn des Crimpprozesses, so dass eine Kontrolle erfolgt, ob das Werkstück richtig in die Aufnahme der Crimpzange eingelegt worden ist.

For a proposal of the invention, an evaluation unit is present in the crimping tool, which is preferably an electronic control unit. The evaluation unit has control logic which carries out an evaluation on the basis of the image taken by the camera.

• This evaluation can consist in that a determination of a type of a workpiece takes place. It is possible, for example, that the crimping tool is aligned by the user so that the camera of the crimping tool produces a receptacle of the workpiece. Based on an automatic image recognition, which is ensured by the control logic, then the type of the workpiece is determined. This can be done by evaluating characteristic points of the workpiece or the outer geometry of the workpiece, to name just a few non-limiting examples.
• Alternatively or additionally, it is possible for the camera to produce a receptacle of the die used in the crimping tool. Based on the shot, the control logic then determines a type of die. It is possible, for example, that the recording detects a barcode, in which case the camera can also be designed as a scanner of the barcode. Accordingly, the recording can capture a QR code. It is possible that the recording detects another marking of the die, in particular a sequence of numbers. Finally, it is possible that the recording captures the geometry of the die.
• Alternatively or cumulatively, it is possible to document the crimping process on the basis of the image recorded by the camera, the documentation being that one or more images of the images, possibly at characteristic process points of the crimping process, are documented by storing he follows. Here, the storage can be done in a memory of the crimping tool or after transmission via the aforementioned interface via the external device.
• It is also possible that an evaluation of the result of the crimping process takes place on the basis of the picture taken by the camera.
• Finally, it is also possible that by means of the recording of the crimping tool, a determination of the position and / or orientation of the workpiece takes place relative to a recording of the crimping tool. This may be the case during or after the crimping process. However, this is preferably done before the start of the crimping process, so that a check is made as to whether the workpiece has been correctly inserted into the receptacle of the crimping tool.

According to a further proposal of the invention, an evaluation unit has control logic which determines a characteristic parameter of the workpiece from a photograph taken by the camera by means of automatic image recognition or image processing. On Based on the determined characteristic parameter, an evaluation of a continuous crimping process and / or the position and / or the orientation of the workpiece relative to a pickup of the crimping tool is then carried out. For example, in order to name an example which does not limit the invention, the evaluation unit can determine from the reception of the workpiece whether the workpiece is a type 1, type 2 or type 3 workpiece. In a memory of the crimping tool different threshold values of a crimping force or different Crimpkraftverläufe can then be stored for the different types of the workpiece. During the crimping process, the detection of a Crimpkraftverlaufs then takes place by a sensor. From the crimping force stored or stored Crimpkraftverlauf for the recognized type of workpiece then the assessment of the crimping process can be done by checking whether a threshold value of the crimping force for this type of workpiece (at the right time) is reached or the actual Crimpkraftverlauf for the recognized Type of workpiece stored nominal crimp force curve (within specified tolerance thresholds) corresponds.

It is possible that only a pair of dies can be used in the crimping tool, wherein within the scope of the invention a die can also have several die halves for crimping different workpieces next to each other. It is also possible, however, that replaceable different dies can be held on the pliers jaws. In this case, the crimping tool can have at least one die receptacle for an exchangeable die. To mention only one example, the die receptacle and the replaceable die may be formed as in the patent DE 19 802 287 C1 the applicant is described. In this case, the crimping tool may comprise a (preferably electronic) detection device which is adapted to detect a marking of the die. According to the state of the art, it must be ensured during the supply of the die for the swaging of the crimping tool by the user or by an automatic feeder that the correct die for the respective workpiece for the pressing of the workpiece is inserted into the swage holder of the crimping tool. Any documentation and an evaluation, for example, of pressing forces of the crimping tool during pressing of the workpiece must then trust that the correct die is arranged in the die receptacle. By contrast, the crimping tool for the embodiment according to the invention is capable of automatically detecting information in the form of a marking relative to the die arranged in the die receptacle. This leads to an increase of the process security, since it can be recognized, whether the correct die or the right type of die is arranged from a group of acceptable types of dies in the die receptacle. The die identified by the label can also be documented in a process documentation. On the basis of the detected marking of the die, a process control during crimping of the workpiece can also take place and / or specific evaluation parameters such as, for example, desired crimp force profiles or crimp force threshold values can be used for the die.

The detection device can in principle be arranged at any point of the crimping tool. Preferably, the detection device and / or an electronic control unit is arranged in the region of a pliers head of the crimping tool, wherein the detection device can also be integrated into the aforementioned electronics module. It is possible that the detection device is arranged in the region or adjacent to the Gesenkaufnahme, wherein the detection device can also be arranged in the region of the pliers head or a pliers jaw. The distance of the detection device from the Gesenkaufnahme can be less than 10 cm, less than 5 cm, less than 4 cm, less than 3 cm, less than 2 cm or even less than 1.5 cm. The detection device can even extend even into the region of the Gesenkaufnahme itself.

• Die Crimpzange kann mit einem Gesenk verwendet werden, welches eine optische Codierung aufweist, welche die Kennzeichnung beinhaltet. Als eine Möglichkeit für eine derartige optische Codierung kann ein Barcode oder eine Ziffernfolge oder ein QR-Code genannt werden. In diesem Fall kann die Erfassungseinrichtung der Crimpzange über eine Leseeinrichtung verfügen, über welche die optische Codierung erfasst werden kann. Diese Leseeinrichtung kann hierbei auch von der Kamera ausgebildet sein.
• Möglich ist auch, dass in der Crimpzange ein Gesenk Einsatz findet, welches eine mechanische Kontaktkontur aufweist, die die Kennzeichnung bereitstellt. In diesem Fall weist die Erfassungseinrichtung eine mechanische Abtasteinrichtung für die mechanische Kontaktkontur auf. Um lediglich ein nicht beschränkendes Beispiel zu nennen, kann die mechanische Abtasteinrichtung einen Abtaststift oder eine Abtastrolle aufweisen, der oder die entlang der mechanischen Kontaktkontur bewegt wird. Das sensierte Signal der Verschiebung des Abtaststifts beinhaltet dann die Kennzeichnung. Möglich ist aber auch, dass eine Reihe oder ein Feld von Abtaststiften gegen eine mechanische Kontaktkontur gedrückt wird, womit die Abtaststifte dann unterschiedlich entsprechend der mechanischen Kontaktkontur ausgelenkt werden und anhand der Auslenkungen der Abtaststifte die mit der Kontaktkontur codierte Kennzeichnung erfasst werden kann.
• Möglich ist des Weiteren, dass das Gesenk eine RFID-Einheit aufweist, über welche die Kennzeichnung bereitgestellt wird. Die RFID-Einheit sendet ein insbesondere hochfrequentes Signal aus, welches die Kennzeichnung beinhaltet. Für den Fall, dass die RFID-Einheit als passive Einheit ausgebildet ist, kann diese ohne eigene Leistungsversorgung ausgebildet sein und infolge einer Anregung durch eine Anregungseinheit, welche ebenfalls Bestandteil der Crimpzange sein kann, in an sich bekannter Weise mit elektrischer Leistung versorgt wird, womit dann das Aussenden des die Kennzeichnung aufweisenden Signals ermöglicht ist. Die Erfassungseinrichtung verfügt über eine Empfangseinrichtung, mittels welcher das von der RFID-Einheit ausgesendete Signal empfangen werden kann. Als Sonderform für diese Art der Kennzeichnung und/oder Übertragung der Kennzeichnung zwischen Gesenk und Crimpzange kann eine Technologie Einsatz finden, die als Nahfeldkommunikation (oder "Near Field Communication", abgekürzt "NFC") bezeichnet wird. Hierbei handelt es sich um einen auf der RFID-Technik basierenden internationalen Übertragungsstandard zum kontaktlosen Austausch von Daten per elektromagnetischer Induktion mittels loser gekoppelter Spulen über kurze Strecken von wenigen Zentimetern, wobei eine Datenübertragungsrate maximal 424 kBit/s betragen kann. Hierbei kann eine verbindungslose Übertragung mittels passiven HF-RFID-Tags nach ISO/IEC 14443 oder ISO/IEC 1563 erfolgen oder eine verbindungsbehaftete Übertragung zwischen gleichwertigen aktiven Transmittern.
  Hinsichtlich weiterer Informationen zu RFID und NFC, die im Rahmen der Erfindung einsetzbar sind, wird auf den Eintrag zu "NFC" sowie "RFID" unter Wikipedia (Datum der Einsichtnahme 11.10.2018) und die hier angegebenen Literaturstellen sowie RFID und NFC betreffende Standardwerke und Veröffentlichungen (insbesondere Klaus Finkenzeller: "RFID-Handbuch: Grundlagen und praktische Anwendungen von Transpondern, kontaktlosen Chipkarten und NFC", Carl Hanser Verlag GmbH + Co. KG, 7. Auflage, ISBN: 9783446439436 ) verwiesen.
• Möglich ist auch, dass die Crimpzange einen Strahlungs- oder Lichtsender aufweist, welcher die Kennzeichnung codiert in einem Strahlungs- oder Lichtsignal versendet. In diesem Fall kann die Erfassungseinrichtung einen Empfänger für ein Strahlungs- oder Lichtsignal aufweisen. Für die Art der Strahlung oder des Lichts, den in dem Gesenk eingesetzten Sender und/oder den in der Erfassungseinrichtung der Crimpzange eingesetzten Empfänger gibt es vielfältige Möglichkeiten. Beispielsweise kann es sich bei dem Sender um einen Infrarotsensor, eine Lichtzelle oder eine Diode handeln. Möglich ist, dass eine Codierung der Kennzeichnung in Form der Frequenz und/oder der Amplitude des ausgesendeten Strahlungs- oder Lichtsignals erfolgt, wobei auch andere, aus der Übertragungs- oder Nachrichtentechnik bekannte Übertragungs- und Codierungsformen genutzt werden können.
• Möglich ist des Weiteren, dass eine Übertragung der Kennzeichnung über eine induktive Kopplung zwischen dem Gesenk und der Erfassungseinrichtung erfolgt. Hierbei erfolgt eine Übertragung der Kennzeichnung über eine elektromagnetische Induktion, wozu beispielsweise eine Signalübertragung zwischen einer Abfrageeinheit und einem zugeordneten Transponder durch Ein- und Ausschalten eines hochfrequenten Magnetfelds erfolgen kann, was einer Amplitudenmodulation entsprechen kann. In dem Transponder wird hierdurch eine elektrische Spannung in der Spule indiziert, die dann über eine Diode gleichgerichtet werden kann. Andere Ausgestaltungsformen sind aber durchaus auch möglich.

There are many possibilities for the type of marking transmitted between the die and the detection device and the design of the detection device, of which only a few possibilities are mentioned below by way of example:

• The crimping tool can be used with a die having an optical coding that includes the marking. As a possibility for such optical coding, a bar code or a digit string or a QR code may be mentioned. In this case, the detection device of the crimping tool can have a reading device, via which the optical coding can be detected. This reading device can also be formed by the camera.
• It is also possible that a die is used in the crimping tool, which has a mechanical contact contour that provides the marking. In this case, the detection device has a mechanical scanning device for the mechanical contact contour. By way of non-limiting example, the mechanical scanning device may include a sensing pin or cam follower, which may be one or more of a scanning stylus is moved along the mechanical contact contour. The sensed signal of displacement of the stylus then includes the tag. It is also possible that a row or a field of scanning pins is pressed against a mechanical contact contour, whereby the scanning pins are then deflected differently according to the mechanical contact contour and based on the deflections of the Abtaststifte encoded with the contact contour marking can be detected.
• It is also possible that the die has an RFID unit, via which the marking is provided. The RFID unit transmits a particular high-frequency signal, which includes the label. In the event that the RFID unit is formed as a passive unit, it may be formed without its own power supply and as a result of excitation by an excitation unit, which may also be part of the crimping tool, is supplied in a conventional manner with electrical power, which then the emission of the signal having the marking is possible. The detection device has a receiving device, by means of which the signal emitted by the RFID unit can be received. As a special form for this type of marking and / or transmission of the marking between die and crimping pliers, a technology can be used, which is referred to as near field communication (or "near field communication", abbreviated to "NFC"). This is an RFID-based international transmission standard for the contactless exchange of data by electromagnetic induction using loosely coupled coils over short distances of a few centimeters, with a maximum data transfer rate of 424 kBit / s. This can be a connectionless transmission by means of passive RF-RFID tags according to ISO / IEC 14443 or ISO / IEC 1563 or a connection-based transmission between equivalent active transmitters.
  For further information on RFID and NFC, which can be used within the scope of the invention, reference is made to the entry for "NFC" and "RFID" at Wikipedia (date of inspection 11.10.2018) and the references cited here, as well as RFID and NFC standard works and Publications (in particular Klaus Finkenzeller: "RFID Handbook: Basics and practical applications of transponders, contactless chip cards and NFC", Carl Hanser Verlag GmbH + Co. KG, 7th edition, ISBN: 9783446439436 ).
• It is also possible that the crimping tool has a radiation or light emitter which transmits the coding in a radiation or light signal. In In this case, the detection device may have a receiver for a radiation or light signal. There are many possibilities for the type of radiation or light, the transmitter used in the die and / or the receiver used in the detection device of the crimping tool. For example, the transmitter may be an infrared sensor, a light cell or a diode. It is possible that an encoding of the marking takes place in the form of the frequency and / or the amplitude of the emitted radiation or light signal, wherein other, known from transmission or telecommunications transmission and coding forms can be used.
• It is also possible that a transmission of the marking takes place via an inductive coupling between the die and the detection device. In this case, a transmission of the label via an electromagnetic induction, including, for example, a signal transmission between an interrogation unit and an associated transponder by switching on and off of a high-frequency magnetic field can take place, which may correspond to an amplitude modulation. In the transponder thereby an electrical voltage in the coil is indexed, which can then be rectified by a diode. Other embodiments are quite possible.

• Möglich ist, dass es sich bei der Kennzeichnung um eine Kennzeichnung des Typs des Gesenks handelt, so dass mehrere baugleiche Gesenke oder auch Gesenke unterschiedlicher Bauart mit einem verbindenden charakteristischen Merkmal oder Einsatzzweck dieselbe Kennzeichnung aufweisen können.
• Möglich ist, aber (alternativ oder kumulativ) auch, dass die Kennzeichnung eindeutig und spezifisch für das jeweilige Gesenk ist, so dass diese ein-eindeutig ist und beispielsweise dem spezifischen Gesenk zugeordnete Kalibrierdaten, Soll-Presskraftverläufe verwendet werden können und in einer Prozessdokumentation exakt dokumentiert werden kann, welches Gesenk für das Verpressen eines Werkstücks eingesetzt worden ist.
• Schließlich ist auch möglich, dass die Kennzeichnung eine Authentifizierung des Gesenks ist, auf Grundlage welcher beispielsweise eine Prüfung möglich ist, ob ein Original-Gesenk und nicht ein nicht authentifiziertes Plagiat eingesetzt ist.

For the embodiment of the marking of the die, which is detected by the detection device, there are many possibilities within the scope of the invention, of which a few examples are given below:

• It is possible that the marking is an identification of the type of die, so that a plurality of identical dies or dies of different design with a connecting characteristic feature or intended use may have the same marking.
• It is possible, but (alternatively or cumulatively) also, that the marking is unique and specific to the respective die, so that it is one-unique and, for example, calibration data associated with the specific die, desired press force profiles can be used and precisely documented in a process documentation can be used, which die has been used for the pressing of a workpiece.
• Finally, it is also possible that the tag is an authentication of the die, based on which, for example, a check is possible as to whether an original die and not an unauthenticated plagiarism is used.

The invention includes embodiments in which the crimping tool has a non-replaceable or an exchangeable die. Preferably, in the crimping tool, the at least one replaceable die has a recess or an inner space. In the recess or the interior, a transmitting unit, in particular an RFID unit, can then be arranged, which emits the identification. Alternatively or cumulatively, a transmission unit for a position signal (in particular a GPS signal) can be arranged in the recess or the interior, which can be integrated, for example, by a GPS unit, which can also be integrated into the interior, the recess or another recess of the die , is generated. The interior or the recess may be open to the outside or closed by a cover or a lacquer layer or other cover, whereby a passage of moisture or dirt to the transmitter unit can be avoided and / or mechanical damage to the transmitter unit can be avoided. Here, the cover, the lid or the lacquer layer is preferably made of a material which has a good radiation transmission for the signal emitted by the transmitting unit. Preferably, the radiation transmission of the cover, lid or lacquer layer is at least 20%, at least 50%, at least 100% or even at least 200 greater than the radiopacity of a base material of the die, in particular in a frequency range from 1.5 GHz to 3 GHz (preferably in a frequency range of 2.0 to 2.8 GHz or 2.2 to 2.6 GHz) or in a frequency range of 500 MHz ± 5%, ± 10% or ± 20%, 1800 MHz ± 5%, ± 10% or ± 20% or 1900 MHz ± 5%, ± 10% or ± 20%. Specifically, the radiopacity may be defined according to one of the standards ASTM D4935-10, IEEE Std 299-2006, IEEEE Std 1128-1998 and ASTM A698 / A698M-07.

For further information on the identification of the die, the detection device, the communication between the die and the detection device and any external devices and the functions provided on the basis of the recognition and transmission of the marking, reference is made to the non-prepublished European patent application EP 18 207 344.5 the Applicant, which is the subject of this European patent application in this regard.

For a further proposal of the invention, the crimping tool on a control unit with control logic, via a recording of a Gesenk by the camera, in particular based on an automatic image recognition based on the geometry of the die or on the basis of a recorded by the recording marking, or on the of Detection device determined identification of the die determines a type of Gesenk. In addition, a type of the workpiece is determined by a recording of the workpiece by the camera. Thus, the control unit with the control logic is able to recognize which type of die and which type of workpiece are to be used in common for an upcoming crimping process. The invention then proposes that an evaluation be carried out by means of the control logic of the control unit on the basis of on the one hand of the determined type of the die and on the other hand of the determined type of the workpiece. In this case, any evaluations are possible, which require that both the type of die and the type of the workpiece are known. For example, an evaluation can be made as to whether the workpiece has been inserted in the correct position and / or position in the die, so that the determined types are taken into account in the evaluation of the recording of the camera from the inserted into the die workpiece. For a particular proposal of the invention, the control unit has control logic which makes an evaluation as to whether the determined type of die and the determined type of workpiece represent a permissible combination. In other words, by the evaluation, it can be recognized if the crimping tool with the die held thereon is to be used for a workpiece which can not be properly crimped with the type of the die.

Alternatively or additionally, based on the determined types of the die and the workpiece, use of specific evaluation criteria can be carried out in order to evaluate whether a proper crimping process has been carried out. For example, different desired pressing forces or Sollpresskraftverläufe or threshold values of the same for a combination of the type of die and the type of workpiece, possibly with different tolerance ranges, be given, which are then used as a basis to make an assessment of the crimping process. In this case, the different specific evaluation criteria can be stored in a memory of the crimping tool. It is also possible that the crimping tool communicates with an external device via an interface, transfers the determined type of die and / or the determined type of workpiece to the external device, and then from the external device the evaluation criteria for the determined types via the interface transmitted to the crimping tool.

In the context of the invention, in a crimping tool network, the control logic of the electronic control unit arranged externally by the crimping tool can fulfill a variety of functions:

1. a) it is possible that the control logic of the external control unit transmits a recording and / or process data (user, date, time, type of die, type of workpiece, crimp force thresholds or gradients, crimp stroke thresholds or gradients) from the crimping tool to the externally controlled by the crimping electronic control unit controls, in which case based on the information transmitted by the external control unit can carry out an evaluation and / or a documentation of this information.
2. b) It is possible that the control logic of the external control unit, a transmission of a target image, which is recognized for a specific workpiece, which is preferably based on the camera, and / or for a specific die, which preferably based on a shot of the camera or Basis of the detection device has been recognized, is controlled by the externally arranged by the crimping electronic control unit to the crimping tool. In the control unit of the crimping tool, the target receptacle can then be used for an evaluation, which is preferably done by comparing the desired recording with the recorded by the camera of the crimping tool receiving the workpiece and / or the die.
3. c) It is possible that the control logic of the external control unit is a transmission of an evaluation criterion which is specific to a specific workpiece and / or a specific die of the crimping tool, which can be detected on the basis of the detection device or based on a recording of the camera the externally controlled by the crimping pliers electronic control unit controls the crimping tool. The control unit of the crimping tool can then base the further evaluation of the crimping process on the transmitted evaluation criterion.
4. d) It is also possible that the control logic of the external control unit transmits a result from the crimping tool to the external control unit. In this case, it is a result of an evaluation made by the control unit of the crimping tool. For example, the control unit of the crimping tool can make an evaluation as to whether the crimping process has been completed properly. This result can then be transmitted to the external control unit, in particular for further documentation.
5. e) Furthermore, the control logic of the external control unit can ensure that a determination of a type of workpiece can be made based on the photograph taken by the camera of the crimping tool and transmitted to the electronic control unit located externally of the crimping tool , For example, the control logic of the external control unit may have an image recognition software that decide on the basis characteristic characteristics of recording and / or by comparison with a priori shots on the one hand for proper crimping processes and on the other hand for improper crimping processes, whether a proper crimping process has been completed.
6. f) It is also possible that by means of the control logic of the external control unit (in a fundamentally corresponding manner) a determination of a type of a die takes place.
7. g) Furthermore, the invention proposes that the control logic of the external control unit based on the recording, which was taken by the camera of the crimping tool and has been transmitted to the externally of the crimping electronic control unit, performs a documentation of a crimping process.
8. h) It is further possible that the control logic of the external control unit based on the recording makes an evaluation of the result of the crimping process, the result of the evaluation then being documented by the external control unit, for example by storage, or transmitted to the crimping tool then it can be displayed whether the crimping process has been properly completed or not.

10. j) For an embodiment of the crimping tool network, a characteristic parameter of the workpiece can be determined by means of the control logic of the external control unit on the basis of the recording by means of automatic image recognition or image processing. On the basis of the thus automatically determined characteristic parameter, an evaluation of the crimping process carried out and / or the position and / or orientation of the workpiece relative to a die receptacle of the crimping tool can then take place.

It is possible that the external electronic control unit communicating with the crimping tool has its own data memory or communicates this with any other control units and / or data memories. The electronic control unit arranged externally by the crimping tool preferably communicates with an external data memory, wherein this communication can take place via a public network, which, however, in turn can take place with a suitable encryption. For example, the external data storage can be configured as cloud storage. It is possible here that different users of crimping tools access a common data memory (in particular cloud memory), the then provided by a central person or a central enterprise, for example the manufacturer of the crimping tool.

In a crimping tool network according to the invention, the electronic control unit arranged externally by the crimping tool can comprise a transmission, an evaluation and / or of a recording received from the camera of the crimping tool and transmitted by the crimping tool to the electronic control unit arranged externally by the crimping tool Process data from the external electronic control unit to the external data memory controls. It is then possible to store and document this transmitted information in the external data memory.

Alternatively or cumulatively, the control logic may control a transmission of a target shot. This target shot is specific to a specific workpiece or type of workpiece and / or a specific die or type of die and stored in the external data memory. This target image is then transmitted from the external data memory to the electronic control unit arranged externally from the crimping tool and can subsequently be used by the electronic control unit arranged externally by the crimping tool for further evaluation or transmitted to the crimping tool, in order to be read by the control unit To be used crimping tool for further evaluation.

Alternatively or cumulatively, it is possible that by means of the control unit a transmission of an evaluation criterion from the external data memory to the electronic control unit arranged externally by the crimping tool is controlled. The evaluation criterion may then be used directly by the external electronic control unit or transmitted to the crimping tool for use by it. The evaluation criterion is specific for a specific workpiece (or a type of workpiece) and / or a die of the crimping tool (or a type of die of the crimping tool) and stored in the external data memory.

Alternatively or cumulatively, it is also possible that the control logic of the external control unit controls a transmission of a result of an evaluation from the electronic control unit arranged externally from the crimping tool to the external data memory in order to be able to document and store the result. Here is the result Result of an evaluation carried out by a control unit of the crimping tool or the electronic control unit arranged externally by the crimping tool.

It is also possible that the control logic of the external control unit based on the recorded from the camera of the crimping tool and transmitted to the externally arranged by the crimping electronic control unit recording a documentation of a crimping process by storing the recording or based on the recording generated data in the external data memory performs. Thus, it is possible, for example, for the user to hold a workpiece in the receiving area of the camera before the crimping process is carried out, for the camera of the crimping tool to record the workpiece, and then for the workpiece or for characteristic features derived therefrom, or for a valuation based on this the crimping tool is transmitted to the external control unit and the control logic of the external control unit ensures that the recording of the workpiece, the characteristics derived therefrom or the evaluation based thereon is stored in the external data memory or in the cloud. In this case, processing, derivation of the characteristic features and / or the evaluation in the control unit of the crimping tool or the external control unit can take place.

A further solution to the problem underlying the invention is a method for crimping a workpiece with a crimping tool, as has been explained above, or with a crimping tool network according to the preceding explanations. In such a method, the following method steps come alternatively or cumulatively for use:
First, a die is inserted into a die holder of the crimping tool. This is followed by a detection of the die via the camera or the detection device of the crimping tool. Subsequently, data that includes information specific to the detected tag of the die, which at least one type of workpiece can be crimped with the die inserted into the die receptacle of the crimping tool, is loaded. This data is loaded from a data memory of the crimping tool, a data memory of the external memory unit or the external data memory. Following this, information about at least one type of workpiece, which can be crimped with the detected die, is output via an output device. This output device may be associated with the crimping tool or the external control unit.

Alternatively or cumulatively, after the insertion of the die into the die receptacle of the crimping tool and the detection of a marking of the die via the detection device of the crimping tool, charging of characteristic data to a desired crimp force course and / or a desired crimping path progression takes place Labeling is / are specific to a data store, which may be a data store of the crimping tool, the external control unit or the external data storage. During a crimping process, that is, during the passage of a crimping stroke, a detection of an actual crimping force signal and / or an actual crimping travel signal then takes place by means of a sensor. This is followed by an evaluation of the crimping process taking into account, on the one hand, the data of the desired crimp force curve and / or the desired Crimpwegverlaufs and on the other hand, the actual Crimpkraftsignals and / or the actual Crimpwegsignals.

Alternatively or additionally, a recording of a workpiece which is to be crimped with the crimping tool is generated by means of the control logic. The control logic then determines the type of workpiece from the shot. An analysis is then made as to whether the die, which has been determined by the camera based on a shot of the die, is suitable for the identified type of workpiece, and finally the generation of an output and / or a documentation entry is then performed depending on the result the analysis. For example, it can be displayed on the crimping tool or the external control unit by means of the output whether the detected die may be used for crimping the recognized workpiece.

Alternatively or additionally, a recording of the workpiece with the camera of the crimping tool can be generated by means of the control unit, which may be the case before, during or after passing through the crimping process.

DESCRIPTION OF THE FIGURES

While Fig. 1 shows a crimping tool 2 in a closed position in the fully assembled state show Fig. 2 and 3 the crimping tool 2 in different partially dismantled states. According to Fig. 3 is due to dismantling only a mechanical pliers part 3 remained (although, however, the mechanical pliers part 3 deviating from Fig. 3 also about the in Fig. 3 disassembled handles 4, 5 can have). The mechanical pliers part 3 represents a principle fully functional crimping pliers, by means of which the desired mechanical processing of the workpiece and the execution of the crimping process can take place. The further components, in particular an electronic component 6, removed from the mechanical tong part 3 merely provide further functions which are not involved in the actual mechanical crimping of the workpiece.

The mechanical pliers part 3 has a pliers head 7 and hand lever 8, 9 (which with the in Fig. 3 not shown handles 4, 5 may be formed). The pliers head 7 extends parallel to a pliers head plane 10. The pliers head plane 10 is at a very small acute angle with respect to the plane of the drawing according to the Fig. 1 to 3 inclined.

The hand lever 8, 9 and jaws 11, 12 move over the Crimphub the crimping tool 2 in the pliers head plane 10, which is done for the illustrated embodiment by pivoting about a pivot axis which is oriented vertically to the pliers head plane 10. The crimping tool 2 has a longitudinal axis 13, which corresponds to the main extension direction of the crimping tool 2 and the bisector of the hand lever 8, 9 corresponds or is parallel to a fixed hand lever 8 and / or oriented parallel to a fixed jaw 11.

The pliers head 7 has a first pliers head part 14, in the region of which the pliers jaws 11, 12 are arranged, as well as a second pliers head part 15, which is arranged between the first pliers head part 14 and the hand levers 8, 9.

In the region of the pliers head part 15, the crimping tool 2 has a housing 16 which has not moved over the working stroke. For the illustrated embodiment, the crimping tool 2 is produced in a plate construction. In this case, the housing 16 is formed with cover plates 17, 18.

For the illustrated embodiment, the housing 16 and the cover plates 17, 18 fixedly connected to a fixed hand lever 8 and a fixed jaw 11, so that the jaw 11 performs no relative movement relative to the hand lever 8 over the working stroke of the crimping tool 2. In the region of the pliers head part 15, the coupling of the hand lever 8, 9 via a drive mechanism 19 with the jaws 11, 12, wherein this for the illustrated embodiment, only for the coupling of the movable hand lever 9 with the movable jaw is valid. Here, any drive mechanism 19 can be used, this preferably has a toggle lever drive with a pressure lever 20. The drive elements of the drive mechanism 19 can in this case be arranged between the cover plates 17, 18 and / or on the outside of these.

In Fig. 3 It can be seen that the pressure lever 20 of the drive mechanism 19 is located outside of a cover plate 17, but this is not necessarily the case. About the Crimphub takes place a relative movement of the pressure lever 20 relative to the fixed pliers part 21, which is formed with the hand lever 8, the housing 16, here the cover plates 17, 18 and the fixed jaw 11.

With regard to the further design of the drive mechanism 19, the drive elements used here, the coupling of the drive elements with each other and with the hand levers 8, 9 and the jaws 11, 12 and the design of the drive elements and the pivot bearing for the drive elements, the hand lever 8, 9 and Pliers jaws 11, 12 is on the non-prepublished European patent application EP 18 166 739.5 directed. In the context of the invention, however, any other crimping tool can be used, in which the jaws are not pivoted relative to each other, but for example, a translational movement of the jaws to each other and / or the hand lever are coupled via another drive mechanism with the jaws. It is also possible that the crimping tool is designed as a so-called multi-mandrel crimping tool, in which more than two mandrels or punches act simultaneously on the peripheral surface of a workpiece for crimping (see, for example, the four-mandrel crimping tool "CS 8" marketed by the applicant. ).

The hand lever 8, 9 each have plate-shaped hand lever struts 22, 23, to which the handles 4, 5 can be pushed from the end of the pliers head 7 remote end and can be attached thereto, which can be done, for example, by a press connection and / or gluing. On the hand lever strut 22, which is part of the fixed pliers part 21, a holder 24 for a battery or an accumulator 25 is attached.

The electronics assembly 6 has a housing 26. The housing 26 has two half-shell-like housing parts 27, 28 and a further housing part 29, which forms a kind of cover 30, on.

Fig. 5 shows the assembly of the two housing parts 27, 28 with each other, while Fig. 6 the lid 30 shows. The housing parts 27, 28 are joined together in a joining direction 31, which is oriented vertically to a parting plane of the housing parts 27, 28 (which here corresponds to the pliers head plane 10). For this purpose, pins or projections of a housing part 27, 28 or pins formed separately from the housing parts 27, 28 (see the connecting pin 55) in the joining direction 31 into corresponding recesses of the housing parts 27, 28, which preferably takes place to form a press connection.

The two housing parts 27, 28 form a guided in the direction of the longitudinal axis through recess 32 with a front opening 33 which faces the pliers head portion 14, and a rear opening 34, which faces the hand levers 8, 9.

For complete assembly of the housing 26, the lid 30 is brought into a joining direction 35, which is oriented parallel to the longitudinal axis 13, in conjunction with the mounted housing parts 27, 28. The cover 30 has in the joining direction 35 protruding pin 36, which occur, in particular with a press fit, in recesses or holes 37 of the housing parts 27, 28th

The housing 26 is formed in the direction of the pliers head plane 10 in the area of the hand levers 8, 9 facing end face approximately V-shaped with legs 38, 39 of the V. In the region of the legs 38, 39 pass over the rear opening 34, the hand lever 8, 9 out of the housing 26 of the electronics assembly 6 out.

Inside the housing 16, the electrical and electronic components of the electronics assembly 6 and in particular a camera 1 are arranged, in an interior which is bounded outwardly by the housing parts 27, 28, 29 and inwardly through the housing 16 of the mechanical Pliers part 3, here the cover plates 17, 18, is limited.

The electronic assembly 6 has two boards 40, 41. The board 41 is supplied via a cable 42 from the battery or the accumulator 25 with electrical energy. The boards 40, 41 are connected to each other via a flexible cable 43. The cable 43 ensures on the one hand the power supply of the board 40 through the board 41 (and thus by the battery or the accumulator 25). On the other hand, an exchange of data takes place via the cable 43 between the two boards 40, 41. The boards are each provided with screws 44 associated housing part 27, 28 screwed. If the electronic assembly 6 is mounted on the mechanical pliers part 3, the boards 40, 41 extend outside of the housing 16, here the cover plates 17, 18, respectively on an outer side of the housing 16 and the cover plates 17, 18, preferably no electrical contact between the housing 16 and the boards 40, 41 takes place. In this assembled state, the cable 43 extends in a cross-section of the mechanical pliers part 3 U-shaped around an end face 45 of the mechanical pliers part 3 from a front side of the mechanical pliers part 3 to a back of the mechanical pliers part 3 (see Fig. 2 ).

In the area of the board 40, an input element 46 is arranged, which here is a button 47. In the area of the board 41, a display or a display 48 is arranged. The board 40 serves to process the input made by the user via the input element 46, while the board 41 serves to drive the display 48.

The housing part 48 has a tongue-like gate, under which the button 47 is arranged. If the user exerts pressure forces on the tongue-like gate 49 of the housing part 28 with the finger, an actuation of the button 47 can take place.

The housing part 27 has a window-like cutout 50. In and behind the cutout 50 is a cover plate 51 which protects the display 48 arranged behind it. As in particular in Fig. 8 can be seen, the board 40 has a here formed by a slot recess 52. A connection cable 53 is passed through the recess 52 of the display 48 to the other side of the board 40 where the connection cable 53 is connected to an electrical connection element 54 via which the board 40 controls the display 48.

In the exploded view according to Fig. 9 it can be seen that the lid 30 is U-shaped. The base leg of the U is located on the top of the mechanical pliers part 3 on the front side 45, which takes place in the region of the fixed pliers part 21. On the other hand, the side legs of the U extend along the housing 16, here along the cover plates 17, 18. The cover 30 is open on the side of the movable jaw 12 and the movable hand lever 9, so that under circumstances for large opening angle of the jaws 11, 12th the movable jaw 12 can come down from the lid 30. In certain circumstances also have the housing parts 27, 28 on the bottom of a corresponding slot, which allows a large opening angle of the movable jaw 12.

In Fig. 3 and 9 is also a connecting pin 55 can be seen, which enters the joining direction 31 in the recesses or holes 56 of the housing parts 27, 28th

By way of the boards 40, 41, there is an activation of luminaires 58. For example, the luminaires 58 are a white LED and / or an RGB LED.

The board 40 carries the camera 1. By means of the board 40 and arranged on the board electronic control unit 57 with associated control logic, the camera 1 is controlled, a recording of the camera 1 generated, evaluated by the camera 1 shot and / or a recording store in a storage unit, not shown, of the crimping tool 2. The circuit board 40 can also form an interface 75, via which a communication with an external electronic control unit 62 can take place (see below).

The housing parts 27, 28 are not transparent to light. On the other hand, the housing part 29 is transparent or has a region completely or in an area assigned to the luminaires 58 and the camera 1, or has a window through which the camera 1 can produce a receptacle.

At least one circuit board 40, 41 has an electronic control unit 57, wherein the two circuit boards 40, 41 together can form a control unit 57.

Within the scope of the invention, an electronic unit 6 of the crimping tool 2 can be equipped with any desired electrical and electronic components, cf. this also includes electronic assemblies according to the prior art. For one embodiment, the electronic component has an electronic control unit, which can also be understood as meaning a plurality of mutually networked partial control units. By way of non-limiting example, the control unit may be a "NXP Kinetis KW41Z, ARM Cortex-MO +, 48MHz" CPU, with the CPU also including a memory (in particular with up to 512KB Flash and up to to 128 kB SRAM). Alternatively or additionally, it is possible for the electronic component to have an input element. There are many possibilities for the design of such an input element. Thus, the input element may serve to directly input a desire or signal of the user. In this case, that can Input element eg. Be a switch, a knob or even a keyboard. But it is also possible that an input element for communication with neighboring components in the electronics module is present. Thus, for example, the input element can be a wired interface (for example a USB interface) or a wireless interface (for example WLAN or Bluetooth). Accordingly, a wireless or wired output element can be present, via which then (wireless or wired), the electronic assembly with an external device for transmission of manual specifications by the user and / or output of operating variables, measurements or other signals by the electronics Unit can communicate. Alternatively or additionally, it is possible that the electronic component has a display element, in particular a (single-line or multi-line) display. Alternatively or additionally, it is possible for the electronic component to have a luminaire which, for example, can be used as an indicator for an operating state, as an indication of an improper working process, as a signal device for a state of charge of a battery or the like. Such a luminaire may, for example, be an LED in any desired color or else an RBG LED. But it is also possible that the lamp is used to illuminate a component of the crimping tool, in particular a locator or the receptacle for the workpiece and / or the environment of the crimping tool in the manner of a flashlight. Finally, it is also possible that a basic lighting of the crimping tool takes place via the lamp in order to make it visually visible, for example in darkened rooms or a toolbox and / or to signal readiness for operation of the crimping tool and / or the electronic component via the lamp. Alternatively or additionally, it is possible for the electronic component to have an acoustic output element. The acoustic output element can be used to communicate with the user in order, for example, to signal operational readiness, to signal complete passage of a power stroke with the achievement of the end position of the jaws, a signal regarding the evaluation of measured force force profiles and / or measured deflections of the jaws and jaws / or to signal from courses of the same. Alternatively or cumulatively, it is possible for the electronic component to have a sensor. Such a sensor may, for example, be an acceleration sensor. For purposes of example only, an example of the invention, the acceleration sensor may be a NXP sensor "MMA8652FC". About such an acceleration sensor can be distinguished whether the crimping tool is stored or moved in the hand of a user. If a recording of the crimping tool detected by a detected after prolonged rest occurring acceleration above the acceleration sensor, a "waking" of the electronic assembly can be done by a change is made from a standby state optimized in terms of power consumption to a standby mode. To mention only other, non-limiting examples of the embodiment of a sensor, it may be the sensor to a force sensor, via which a forceps force or crimping force is measured, or a displacement sensor, which the working stroke of the jaws or any Drive element of the drive mechanism detected. It is possible that for wireless communication with the crimping tool a 2.4 GHz wireless technology according to the IEEE 802.15.4 standard is used, whereby a technique "Bluetooth Low Energy 4.2" can be used. It is possible that the sensor is a counter, which may be designed in particular as an IR proximity sensor, which is marketed under the "AMS TCS 73327". For example, an OLED display can be used as the display element, here, for example, a product which is marketed under the designation "VGM 096064 A5W01 and has a white monochrome resolution of 96 × 64 pixels.

Assuming that the mechanical pliers part 3 in the pliers head part 15, in the region of which the electronic component 6 is arranged, has a rectangular cross section, in which opposite sides are formed by cover plates of the pliers head 7, the electronics assembly 6 extend in a portion of a page in the cross section, extend "around a corner" in the region of two sides of the rectangle around the mechanical pliers part 3 or, for example, U-shaped around two corners along three adjacent sides of the rectangle. It is also possible that the electronic assembly has 6 subunits, which are arranged in the region of one side of the rectangular cross section or in the region of different sides of the rectangular cross section are attached to this cross section. For a particular embodiment of the invention, the electronic assembly 6 extends on two opposite sides of the pliers head part 15, wherein these opposite sides in the above-described rectangular cross-section of the mechanical pliers part 3 are the longer sides of the rectangle, which of the cover plates of the mechanical pliers part 3 may be formed. This embodiment has the advantage that, on the one hand, a good fastening of the electronic component 6, in particular on the mentioned cover plates of the pliers head 7, is ensured. On the other hand, the pliers head part 15 has an enlarged extent in the region of these opposite sides, so that a larger number of components of the electronic component 6 or even larger such components can be arranged in the region of these sides.

The camera 1 is preferably arranged and aligned in the electronic module 6 so that the camera 1 (through a window of the housing of the electronic component 6 or a transparent portion of the housing of the electronic module 6) is a receptacle from the vicinity of the crimping tool 2, of the pliers head 7, dies 66, 67 of the crimping tool 2 and / or a workpiece arranged in the dies of the crimping tool 2. The camera 1 preferably generates a recording in a direction oriented away from the hand levers 8, 9.

It is possible for a particular proposal that the electronics assembly 6 has a continuous edge-closed recess. The mechanical gripper part 3 then extends through the edge-closed recess. In other words, the electronic component 6 for this embodiment extends around the mechanical pliers part 3 in the circumferential direction throughout. It is possible, for example, that for this embodiment, the electronic assembly 6 is formed as a kind of ring. As a result of the continuous edge-closed recess, the electronics assembly 6 has a front opening and a rear opening. In the region of the front opening extend from the electronic assembly 6, the jaws 11, 12 out, while extending from the rear opening of the edge-closed recess of the electronic assembly 6, the hand lever 8, 9 out. But it is also possible that the jaws 11, 12 and the hand lever 8, 9 of the associated opening before or. are downstream, in which case a drive element of the drive mechanism 19 or a housing of the pliers head 7 may extend out of the opening.

For the choice of the material of the housing of the electronic assembly 6 and the same configuration there are many possibilities. For example, the housing may be made with any number of housing parts made of plastic. For a proposal of the invention, the housing of the electronic module 6, the half-shell-like housing parts 27, 28. The two half-shell-like housing parts 27, 28 are closed in a mounted state in the circumferential direction, whereby they form a kind of ring. The two housing parts 27, 28 then extend around the mechanical pliers part 3 in the assembled state. Inwardly of these two half-shell-like housing parts 27, 28, the mechanical pliers part 3 is then arranged, so that an interior of the electronics assembly 6, in which the components of the electronics assembly 6 are accommodated, is bounded by the two outer shell-like housing parts 27, 28 on the outside while this interior is then inboard is limited by the mechanical pliers part 3, in particular with cover plates. Preferably, close the two half-shell-like housing parts 27, 28 inside tight and possibly even with a seal to the mechanical pliers part 3 at. The connection of the two housing parts 27, 28 may be arbitrary with each other and / or with the mechanical pliers part. Thus, for example, it is possible that the two housing parts 27, 28 are clipped together, glued, latched, locked, pressed and / or screwed together and / or with the mechanical pliers part 3.

The electronics assembly 6 preferably has the boards 40, 41, which carry the electrical and electronic components of the electronic assembly 6, in particular the camera 1, and / or an electronic control unit or are connected thereto. It is possible that in each case arranged on one side of the pliers head part a circuit board 40, 41, wherein the boards can be screwed to the housing parts 27, 28, so that they do not have to be connected to the mechanical pliers part 3. For one embodiment, all components of the electronics package 6 are attached to the housing, which in turn is then secured to the mechanical tong 3.

For the use of two arranged on opposite sides of the pliers head part 15 boards 40, 41, the two boards 40, 41 may be connected to each other via the cable 43. It is possible that the cable 43 extends through a recess of the mechanical pliers part 3 therethrough. For a further proposal, however, the two boards 40, 41 are connected to each other via a cable 43 which extends in the circumferential direction about the mechanical pliers part 3 from one board 40 to the other board 41. For the aforementioned example, according to which the mechanical pliers part 3 has a rectangular cross-section in the region of the electronic component 6 whose longer sides are formed by cover plates, the two circuit boards 40, 41 are each arranged in the region of an outer side of a cover plate and the cable 43 then extends from these longer sides of the rectangular cross-section around the corners of the rectangle and along a shorter side of the rectangular cross-section from one board 40 to the other board 41. The cable 43 may be, for example, a flexible ribbon cable. The cable 43 extends in this case in an annular interior, which is bounded on the inside of the mechanical pliers part 3 and externally of a housing of the electronics assembly 6. For an embodiment of the crimping tool 2, the housing 26 of the electronic component 6 has a light-permeable or partially transparent portion 60. For example, this portion of the further housing part 29 may be formed, which forms the the jaws 11, 12 facing the front side of the electronic component 6. For this embodiment, the light 58 and / or the camera 1 is / is arranged inside the housing 26 of the electronic component 6. This camera 1 is arranged and aligned in such a way that the camera 1 can take a picture through the transmissive partial area 60. By means of the light 58, a lighting of the surrounding area of the electronic unit 6, that is, for example, a locator of the crimping tool 2 or a receptacle for the workpiece, can possibly take place. It is also possible that the light of the lamp 58 passes through the permeable portion 60 and allows use in the manner of a flashlight function over which an environment of the crimping tool 2 can be illuminated. On the other hand, if the light emitted by the light 58 strikes a partially transmissive partial region 60, a reflection of the partial region 60 can take place in the region wherewith, for example, a type of colored ring can be produced on the electronic component 6. Different operating states of the electronic component 6 can be made visible depending on the illumination via this backlit portion 60. For example, it can be signaled via a flashing subarea that contact is attempted via a wireless connection, while it can be signaled with permanent backlighting that contact has been established via the wireless connection. Alternatively or additionally, it is possible that the backlighting of the partial area 60, possibly with a different color, signals that the electronic unit 6 is ready for operation. With regard to further possibilities of using the light emitted by the light 58, the orientation of the light 58 and the integration in the crimping tool 2 is exemplified in the publications US 2011/0235312 A1 such as EP 3 312 949 A1 directed.

Another proposal is dedicated to detecting a movement of the drive mechanism 19 and thus the movement of the jaws 11, 12. It is proposed that the drive mechanism 19 has a drive element, which is arranged on the mechanical pincer part 3 outboard. To mention only a non-limiting example, it may be the pressure lever 20 of the crimping tool 2, which according to the non-prepublished European patent application EP 18 166 739.5 may be formed and in which the pressure lever is arranged outside of cover plates of the pliers head. This drive element can then move (possibly with a small distance) relative to a sensor of the electronic component 6. The sensor can then control the movement of the drive element and so that the drive mechanism 19 and the jaws 11, 12 detect. In this case, the sensor can detect a path. But it is also possible that the sensor merely signals a changeover for the achievement of a predetermined partial stroke of the working stroke, for example the exceeding of 15% of the working stroke or the reaching of the closed position. For example, a sensor of the type "IR proximity sensor" with a counter can be used for this purpose (compare the commercially sold product "AMS TCS 73327").

Die Bewertung des mit der Crimpzange 2 durchgeführten Bearbeitungsvorgangs kann aber auch auf Grundlage einer von der Kamera 1 erzeugten Aufnahme des Werkstücks erfolgen.
• Möglich ist, dass die Steuerlogik der elektronischen Steuereinheit 57 eine Speicherung von Daten vornimmt, insbesondere die Zahl der durchlaufenden Arbeitshübe, diskrete Werte oder Verläufe der Zangenkraft und/oder des Weges der Zangenbacken, eine Aufnahme der Kamera 1 u. ä. Die derart gespeicherten Daten können dann später ausgelesen werden und zur Dokumentation des mit der Crimpzange 2 erzeugten Arbeitsergebnisses verwendet werden.
• Die Erfindung umfasst auch Ausführungsformen, bei welcher Daten gespeichert werden wie bspw. die Zahl der durchlaufenden Arbeitshübe oder eine Aufnahme der Kamera 1, wobei ein Auslesen der derart gespeicherten Daten aber lediglich durch den Hersteller erfolgen kann, womit der Hersteller auf Grundlage dieser Daten dann eine Beurteilung eines etwaigen Versagens der Crimpzange vornehmen kann.
• Möglich ist, dass durch die Steuerlogik der elektronischen Steuereinheit 57 ein Energiemanagement derart erfolgt, dass vermieden wird, dass die Elektronik-Baueinheit zu viel elektrische Energie verbraucht, wenn die Crimpzange überhaupt nicht genutzt wird und bspw. in einer Werkzeugkiste oder auf einem Tisch ruht. Für diese Ausgestaltung nimmt die Crimpzange grundsätzlich einen Standby-Modus ein, in welchem die elektrische Leistungsaufnahme minimiert wird. In diesem Fall wird dennoch in dem Standby-Modus ein Signal eines Beschleunigungssensors derart ausgewertet, dass eine Bewegung der Crimpzange erkannt wird insbesondere durch eine auftretende gemessene Beschleunigung. Wird eine derartige Bewegung der Crimpzange durch die Aufnahme der Crimpzange durch den Benutzer erkannt, aktiviert die Steuerlogik der elektronischen Steuereinheit einen Bereitschaftsmodus, so dass der Standby-Modus verlassen wird. In dem Bereitschaftsmodus kann dann eine erweiterte Funktionalität der Elektronik-Baueinheit gewährleistet werden, so dass die Elektronik-Baueinheit "aufgeweckt" wird. Für eine Ausgestaltung der Erfindung wird in dem Bereitschaftsmodus bspw. über einen Sensor erfasst, ob eine Betätigung der Crimpzange erfolgt. Der Sensor kann bspw. erfassen, ob ein Durchlaufen des Arbeitshubs erfolgt, was über einen Wegsensor oder einen Endlagenschalter erfolgen kann. Eine derartige Überwachung, ob eine Betätigung der Crimpzange erfolgt, kann bspw. für einen vorgegebenen Zeitraum (insbesondere 10 Sekunden) nach dem Wechsel in den Bereitschaftsmodus erfolgen. Erfolgt innerhalb dieses Zeitraums keine Betätigung der Crimpzange, erfolgt eine automatische Rückkehr in den Standby-Modus. Auch möglich ist, dass eine Rückkehr in den Standby-Modus durch die Steuerlogik herbeigeführt wird, wenn nach Aktivierung des Bereitschaftsmodus über den Beschleunigungssensor erkannt wird, dass sich die Crimpzange für eine vorgegebene Zeitspanne in einem Ruhezustand ohne auftretende Bewegung befindet.
• Möglich ist, dass für den Fall, dass (ggf. nach einem Wechsel von dem Standby-Modus in den Bereitschaftsmodus wie zuvor erläutert) eine Betätigung der Crimpzange 2 über einen Sensor erfasst wird, mittels der Steuerlogik der elektronischen Steuereinheit ein Display und/oder eine Leuchte aktiviert wird. Für die Leuchte kann bspw. dem Benutzer die Betriebsbereitschaft der Crimpzange signalisiert werden. Des Weiteren kann mittels der Aktivierung des Displays die Anzeige der für den Benutzer relevanten Informationen an dem Display initiiert werden.
• Wird mittels der Steuerlogik erfasst, dass für eine vorgegebene erste Zeitspanne keine Betätigung der Crimpzange erfolgt ist oder aber für eine vorgegebene zweite Zeitspanne keine Bewegung der Crimpzange erfolgt ist, kann ein Display und/oder eine Leuchte deaktiviert werden. Für diese Ausgestaltung ist vorzugsweise die erste Zeitspanne länger als die zweite Zeitspanne.
• Die Steuerlogik der elektronischen Steuereinheit 57 kann zuständig sein für das Betreiben einer drahtlosen Sende- und/oder Empfangseinrichtung. Über die Empfangseinrichtung kann bspw. eine Konfiguration der Crimpzange und/oder der Elektronik-Baueinheit erfolgen. Hingegen kann über die drahtlose Sendeeinrichtung bspw. ein Übertragen von Daten hinsichtlich des durchgeführten Arbeitsprozesses an eine externe Auswerteeinrichtung erfolgen.
• Möglich ist, dass die Steuerlogik der elektronischen Steuereinheit 57 eine Ansteuerung mindestens einer Leuchte (bspw. einer LED) vornimmt. Diese Ansteuerung kann in dem Aktivieren und Deaktivieren der Leuchte, der Veränderung der Farbe der Leuchte, dem Wechsel von einem permanenten zu einem blinkenden Betrieb der Leuchte u. ä. bestehen.
• Möglich ist, dass die Steuerlogik der elektronischen Steuereinheit 57 eine Leuchte oder eine Anzeige dimmt, wenn erkannt wird, dass ein Ladezustand einer Batterie oder eines Akkumulators einen Schwellwert unterschreitet, wodurch der Energieverbrauch der Crimpzange reduziert wird.
• Möglich ist, dass die Steuerlogik der elektronischen Steuereinheit 57 die Vorgabe eines Tasters, der von einem Benutzer betätigt werden kann, auswertet, indem bei einem Betätigen des Tasters für eine erste Zeitspanne eine Leuchte aktiviert wird, während bei einem Betätigen des Tasters für eine zweite Zeitspanne eine drahtlose Verbindung aktiviert wird. So kann bspw. bei einem Betätigen des Tasters für die erste Zeitspanne die Leuchte aktiviert werden, um die Beleuchtung der Umgebung der Crimpzange, also eine Funktion ähnlich einer Taschenlampe, zu aktivieren, während für die Betätigung des Tasters für die zweite Zeitspanne ein Verbindungsaufbau (bspw. über Bluetooths) ermöglicht wird.
• Möglich ist, dass die Steuerlogik eine (Um-) Konfiguration der Crimpzange ermöglicht, was mittels einer drahtlosen oder kabelgebundenen Kommunikation erfolgen kann oder sogar durch direkte Eingabe an einem Eingabefeld der Crimpzange. Um lediglich einige nicht beschränkende Beispiele zu nennen, kann die Konfiguration darin bestehen, dass ein Name des Benutzers oder des Unternehmens, in welchem die Crimpzange verwendet wird, oder ein Name oder eine Kennzeichnung des Herstellers auf die Crimpzange "aufgespielt" wird. Möglich ist aber auch, dass die Konfiguration darin besteht, dass Kalibrierfaktoren für in der Crimpzange eingesetzte Sensoren übermittelt werden oder auch der Crimpzange zur Kenntnis gebracht wird, welche Art von Werkstück mit der Crimpzange bearbeitet werden soll, wobei dann unter Umständen auch unterschiedliche Betriebsweisen der Crimpzange von der Steuerlogik ausgesteuert werden können.
• Möglich ist, dass die Steuerlogik erfasst, ob eine Schließstellung des Handhebels erreicht worden ist. Dies kann durch Auswertung des Signals eines einen kontinuierlichen Weg erfassenden Sensors oder auch eines Endlagenschalters erfolgen. Dies kann einerseits genutzt werden für ein Zählen der Arbeitshübe der Crimpzange und andererseits für die Auswertung, ob der Arbeitshub der Crimpzange ordnungsgemäß durchlaufen worden ist. Des Weiteren kann auch weggesteuert, insbesondere mit Erreichen der Schließstellung des Handhebels, automatisch die Erzeugung einer Aufnahme durch die Kamera 1 ausgelöst werden.
• Möglich ist, dass die Steuerlogik der elektronischen Steuereinheit 57 eine Ortungsfunktion steuert, über welche eine Ortung der Crimpzange möglich ist. Alternativ oder zusätzlich möglich ist, dass die Steuerlogik eine Diebstahlsicherung der Crimpzange steuert. Verfügt bspw. die Crimpzange über ein GPS und eine Sende- und/oder Empfangseinrichtung, bspw. mit einer Mobilkarte, kann bei der Suche nach der Crimpzange bspw. an ein Smartphone eine aktuelle Position der Crimpzange übertragen werden. Möglich ist aber auch, dass die Ortungsfunktion lediglich darin besteht, dass über ein externes Gerät wie ein Smartphone aktiviert wird, dass die Crimpzange Licht aussendet oder auch ein akustisches Signal aussendet, auf Grundlage dessen das Auffinden der Crimpzange vereinfacht ist. Möglich ist des Weiteren, dass für eine Diebstahlsicherung ein Signal für die Aktivierung der Diebstahlsicherung an die Crimpzange übertragen wird, womit dann die Crimpzange durch eine durch einen Aktuator gesteuerte Verriegelung blockiert werden kann oder eine Kupplung des Antriebsmechanismus in einen geöffneten Zustand überführt wird.
• Möglich ist des Weiteren, dass die Steuerlogik der elektronischen Steuereinheit 57 eine elektronische Einlegekontrolle gewährleistet, über die eine Kontrolle erfolgt, ob ein bestimmungsgemäßes Einlegen eines Werkstücks in die Zangenbacken erfolgt ist. Dies kann bspw. durch einen Kontakt im Bereich der Aufnahme der Crimpzange für das Werkstück erfolgen. Je nach Kontaktkraft oder Betätigen des Kontakts kann dann mittels der Steuerlogik darauf geschlossen werden, ob das Werkstück korrekt in die Aufnahme eingelegt worden ist oder nicht. Ebenfalls möglich ist, dass die elektronische Einlegekontrolle darauf basiert, dass mittels der Kamera 1 eine Aufnahme des Werkstücks in der von den Gesenken 66, 67 gebildeten Aufnahme erzeugt wird, die dann ausgewertet wird durch Vergleich mit einer Soll-Aufnahme oder mittels einer Bilderkennung und dem Vergleich charakteristischer Merkmale mit charakteristischen Soll-Merkmalen.
• Des Weiteren kann die Steuerlogik zuständig sein für die Steuerung einer Anzeige, die bspw. einen Namen oder eine Kennzeichnung eines Herstellers, eines Besitzers oder eines Benutzers, einen Ladezustand einer Batterie oder eines Akkumulators, eine gemessene Zangenbackenkraft oder einen gemessenen Zangenbackenweg oder einen Verlauf derselben, eine Zahl der durchlaufenden Arbeitshübe oder eine Zahl der noch verbleibenden Arbeitshübe, das Ergebnis einer Bewertung eines mit der Crimpzange durchgeführten Bearbeitungsvorgangs, das Ergebnis eines Vergleichs einer ermittelten Zahl von durchlaufenden Arbeitshüben mit einem Schwellwert, eine Aufnahme der Kamera 1, aus der Aufnahme der Kamera 1 abgeleitete Informationen oder Auswerteergebnisse und/oder einen Hinweis hinsichtlich einer erforderlichen Wartung der Crimpzange anzeigt.

A further embodiment has the guarantee of further functions by a control logic of the electronic control unit 57 to the object:

• It is possible that by means of the control logic of the electronic control unit 57, an evaluation of a state of charge of a battery or a rechargeable battery takes place. It is possible, for example, that when a low state of charge is detected, an indication is made via an LED or a display. It is also possible that falls below a threshold value of a state of charge of the battery, an energy saving mode is activated, in which, for example, a lamp or a display is dimmed or even disabled.
• It is possible that the control logic of the electronic control unit 57 evaluates a forceps jaw force determined by a sensor or a jaw path (or a path of a component of the drive mechanism correlating therewith) and / or a recording generated by the camera 1, taking into account a calibration factor, a Evaluation criterion, image recognition or image processing, storage for later further processing, a comparison with a threshold or a target recording, a comparison with a setpoint curve or characteristic points u. a can take place.
• It is possible that the control logic of the electronic control unit 57 determines the number of continuous working strokes, which may be, for example, a total of the crimping pliers since manufacture or a last maintenance working strokes or the continuous on a day or within a predetermined period strokes , It is possible that the number of continuous working strokes is compared with a threshold, in which case the user can be signaled when the threshold value is exceeded that the crimping tool 2 has to be serviced immediately or after a certain number of further working strokes or even becomes unusable. It is also conceivable that when exceeding a specification for the maximum continuous working strokes, a deactivation of the crimping tool 2 from the electronic Control unit is brought about what can be done, for example, by means of a locking of the moving parts of the crimping tool 2 or the release of an integrated clutch in the drive mechanism. For further details on the determination and evaluation of a number of continuous working strokes is exemplified in the European patent application EP 2 995 424 A1 directed.
• It is also possible that the control logic of the electronic control unit 57 carries out an evaluation of a machining operation carried out with the crimping tool 2. This evaluation can for example take place in that a detected force of the force (for example a maximum of the crimping force or the crimping force for reaching a predetermined partial stroke of the working stroke) is within a predetermined range of the force of the forceps or a course of the forceps within specified tolerances for an ideal course of the forceps Forceps lies. However, the evaluation of the machining process performed with the crimping tool 2 can also be based on a recording of the workpiece generated by the camera 1.
• It is possible that the control logic of the electronic control unit 57 carries out a storage of data, in particular the number of continuous working strokes, discrete values or courses of the forceps and / or the path of the jaws, a recording of the camera 1 u. Ä. The data stored in this way can then be read out later and used to document the work result generated with the crimping tool 2.
• The invention also encompasses embodiments in which data is stored, such as the number of continuous strokes or a shot of the camera 1, whereby a readout of the data stored in this way can only be done by the manufacturer, with which the manufacturer then uses a Assessment of any failure of the crimping tool can make.
• It is possible that by the control logic of the electronic control unit 57, an energy management takes place such that it is avoided that the electronic unit consumes too much electrical energy when the crimping tool is not used at all and, for example, rests in a tool box or on a table. For this embodiment, the crimping tool basically assumes a standby mode, in which the electrical power consumption is minimized. In this case, nevertheless, in the standby mode, a signal of an acceleration sensor is evaluated in such a way that a movement of the crimping tool is detected, in particular by an occurring measured acceleration. If such a movement of the crimping tool is detected by the user receiving the crimping tool, the control logic of the electronic control unit activates a standby mode, so that the standby mode is exited. In the standby mode, an extended functionality of the electronic module can then be ensured, so that the electronic module is "woken up". For an embodiment of the invention, in the standby mode, for example, via a sensor detects whether an operation of the crimping tool takes place. The sensor can, for example, detect whether there is a passage through the working stroke, which can take place via a displacement sensor or a limit switch. Such monitoring, whether an operation of the crimping tool takes place, can, for example, for a predetermined period (in particular 10 seconds) after switching to the standby mode. If no operation of the crimping pliers occurs within this period, an automatic return to standby mode takes place. It is also possible that a return to the standby mode is brought about by the control logic if, after activation of the standby mode via the acceleration sensor, it is detected that the crimping tool is in an idle state for a predetermined period without any movement occurring.
• It is possible that in the event that (if necessary after switching from the standby mode to the standby mode as explained above) an operation of the crimping tool 2 is detected by a sensor, by means of the control logic of the electronic control unit, a display and / or a Lamp is activated. For example, the user can be signaled that the crimping tool is ready for operation. Furthermore, by means of the activation of the display, the display of the information relevant for the user can be initiated on the display.
• If it is detected by means of the control logic that no operation of the crimping tool has taken place for a predetermined first period of time or no movement of the crimping tool has taken place for a predetermined second time period, a display and / or a luminaire can be deactivated. For this embodiment, preferably, the first time period is longer than the second time period.
• The control logic of the electronic control unit 57 may be responsible for operating a wireless transmitting and / or receiving device. For example, a configuration of the crimping tool and / or the electronic component can take place via the receiving device. On the other hand, via the wireless transmitting device, for example, a transfer of data concerning the work process carried out to an external evaluation device can take place.
• It is possible for the control logic of the electronic control unit 57 to control at least one light (for example an LED). This control can be in the activation and deactivation of the lamp, the change in the color of the lamp, the change from a permanent to a flashing operation of the lamp u. Ä. exist.
• It is possible that the control logic of the electronic control unit 57 dims a lamp or a display when it is detected that a state of charge of a battery or a battery is below a threshold value, whereby the power consumption of the crimping tool is reduced.
• It is possible that the control logic of the electronic control unit 57, the default of a button that can be operated by a user evaluates by a light on the push button for a first time period is activated, while pressing the button for a second period a wireless connection is activated. Thus, for example, upon actuation of the button for the first time period, the light can be activated to activate the lighting of the environment of the crimping tool, ie a function similar to a flashlight, while for the operation of the button for the second time period a connection setup (eg via Bluetooth).
• It is possible that the control logic allows (re) configuration of the crimping tool, which can be done by means of wireless or wired communication or even by direct input to an input field of the crimping tool. To name just a few non-limiting examples, the configuration may be that a name of the user or the company in which the crimping tool is used, or a name or label of the manufacturer, is "applied" to the crimping tool. However, it is also possible that the configuration consists in that calibration factors are transmitted for sensors used in the crimping tool or the crimping tool is made aware of which type of workpiece is to be processed with the crimping tool, in which case also different modes of operation of the crimping tool can be controlled by the control logic.
• It is possible that the control logic detects whether a closed position of the hand lever has been reached. This can be done by evaluating the signal of a continuous path detecting sensor or a limit switch. On the one hand, this can be used for counting the working strokes of the crimping tool and, on the other hand, for evaluating whether the working stroke of the crimping tool has been properly completed. Furthermore, it can also be controlled away, in particular when the closed position is reached of the hand lever, automatically trigger the generation of a recording by the camera 1.
• It is possible that the control logic of the electronic control unit 57 controls a locating function, via which a location of the crimping tool is possible. Alternatively or additionally, it is possible that the control logic controls an anti-theft device of the crimping tool. If, for example, the crimping tool has a GPS and a transmitting and / or receiving device, for example with a mobile card, a current position of the crimping tool can be transmitted to a smartphone when searching for the crimping tool, for example. However, it is also possible that the locating function merely consists in activating via an external device such as a smartphone that the crimping tool emits light or emits an acoustic signal on the basis of which the finding of the crimping tool is simplified. It is also possible that a signal for the activation of the anti-theft device is transmitted to the crimping tool for an anti-theft device, whereby then the crimping tool can be blocked by a controlled by an actuator locking or a clutch of the drive mechanism is transferred to an open state.
• It is further possible that the control logic of the electronic control unit 57 ensures an electronic insertion control, via which a check is made as to whether an intended insertion of a workpiece into the forceps jaws has taken place. This can be done, for example, by a contact in the area of the recording of the crimping tool for the workpiece. Depending on the contact force or pressing the contact can then be closed by means of the control logic, whether the workpiece has been correctly inserted into the receptacle or not. It is also possible that the electronic insertion control is based on the fact that by means of the camera 1 a recording of the workpiece in the recording formed by the dies 66, 67 is generated, which is then evaluated by comparison with a target shot or by means of an image recognition and the Comparison of characteristic features with characteristic target features.
• Furthermore, the control logic may be responsible for controlling a display, for example, a name or a label of a manufacturer, an owner or a user, a state of charge of a battery or a rechargeable battery, a measured forceps jaw force or a measured forceps jaw travel or a course of the same, a number of continuous working strokes or a number of remaining strokes, the result of an evaluation of a performed with the crimping tool Processing operation, the result of a comparison of a determined number of continuous work strokes with a threshold, a recording of the camera 1, from the recording of the camera 1 derived information or evaluation results and / or an indication of a required maintenance of the crimping tool displays.

Fig. 10 shows a crimping tool network 61 with a crimping tool (which is a crimping tool 2 according to FIG Fig. 1 to 9 can act, or any other crimping tool), with an external electronic control unit 62 and with an external data memory 63. The crimping tool 2 has formed by the jaws 11, 12 female retainers 64, 65. The electronics assembly 6 is adjacent to the Gesenkaufnahmen 64, 65 arranged. The electronic assembly 6 is held on the mechanical pliers part 3, wherein preferably the electronic assembly 6 is arranged on both sides of the mechanical pliers part 3 and the electronics assembly 6 extends partially or completely around the mechanical pliers part 3.

In the swivel receptacles 64, 65 exchangeable dies 66, 67 are held. The force flow of the crimping force acting on a die 66, 67 extends at least partially via a sensor 68, which detects the crimping force acting on the die 66, 67. With regard to possibilities of the design of the sensor 68 and its integration into a crimping tool 2, here with a division of the crimping force on a Teilcrimpkraft which acts on the sensor 68, and another Teilcrimpkraft, which is guided in mechanical parallel connection to the sensor 68, is on the European Patent Application EP 3 396 796 A1 referred to, which is the subject of the present patent application.

The dies 66, 67 each have a tag 69, 70 that is specific to the associated die 66, 67 or type of die 66, 67.

The electronic component 6 has an identification processing unit 71, which has a detection device 72, an electronic control unit 73, an output device 74 and an interface 75. Here, the camera 1 is integrated into the electronic package 6 or the tag processing unit 71.

The identification processing unit 71 communicates on the one hand with the sensor 68 in order to transmit an actual crimping force signal 76 measured by the sensor 68 during the crimping stroke. It is possible that the sensor 68 or another sensor also determines an actual crimping signal 77 during the crimping stroke. The identification processing unit 71, here the detection device 72, detects the markings 69, 70 of the dies 66, 67, this also by detecting the marking 69, 70 in the form of an optical coding by the camera 1 or a reading device of the detection device 72 Detection of a marking in the form of a mechanical contact contour by a mechanical scanning device, by an RFID unit 78, 79 of the dies 66, 67, which emits the marking 69, 70, which is then detected by the detection device 72, a Nahfeldkommunikation or a radiation or light emitters 80, 81 of the dies 66, 67, whose emitted light or transmitted radiation encodes the identification 69, 70 and is detected by the detection device 72, or can be made by an inductive coupling between a die 66, 67 and the detection device 72, merely to name a few non-limiting examples.

The tag processing unit 71 (or the electronics package 6) communicates via the interface 75 with the external electronic control unit 62, which may be formed as a PC, tablet, laptop or smartphone. The electronic control unit 62 has an output device 82, a data memory 83 and a workpiece specification device 84. Preferably, the communication 85 between the interface 75 and the electronic control unit 62 is bidirectional. The electronic control unit 62 is further connected via suitable interfaces in communication 86 with the data memory 63 (located externally of the control unit 62 and the crimping tool 2), which is preferably a cloud memory 87.

The crimping tool 2 communicates by means of the communication 85 with the control unit 62, which in turn communicates by means of the communication 86 with the data memory 63, with which the crimping tool network 61 is formed.

Fig. 11 shows a method for crimping a workpiece, in particular with a crimping tool according to Fig. 1 to 9 or a crimping tool network 61 according to Fig. 10 :
In a method step 88, a user selects dies 66, 67 of a specific type from a plurality of pairs of dies and inserts them into die receptacles 64, 65 of a crimping tool 2.

In a method step 89, the markings 69, 70 of the dies 66, 67 are detected by the detection device 72 or the camera 1. As explained above, this can be achieved by detecting an optical marking such as a bar code or QR code by means of a reading device mechanical scanning of a scanning contour, by receiving a signal of an RFID unit 78, 79, by inductive coupling u. Ä.

In a method step 90, the detected identifiers 69, 70 are processed by the control unit 73. It is possible that an output is produced at the output device 74 on the basis of this processing. For example, output device 74 may display which specific die 66, 67 (for example, a current die number) or what type of die is involved. It is also possible that the type of recognized Gesenk is displayed on the output device 74 and / or types of workpieces, in particular workpiece numbers or type numbers are displayed, which can be edited with the identified type of dies 66, 67. It is also possible that the number of crimping strokes is displayed on the output device 74, which have already passed through the dies 66, 67, wherein with the exceeding of a threshold value for the number of crimping strokes also at the output device 74, a request for replacement of the dies 66, 67 can be displayed. It is possible that information required for this evaluation, such as the number of working strokes swept by the dies 66, 67, which are counted via a suitable counting device of the crimping tool 2, an assignment of the different markings 69, 70 of different pairs of dies to a type of the workpiece u. Ä. Are stored in a memory unit of the identification processing unit 71 or the electronics assembly 6. However, this is not the case for the exemplary embodiment described here.

Rather, in a method step 91, a transmission of the marking 69, 70 (or an information thereof determined as a result of the processing by the control unit 73) via the interface 75 by means of the communication 85 to the control unit 62, which is for example a smartphone or a Tablet is trading. In this case, the transmission preferably takes place wirelessly by means of WLAN or Bluetooth or by cable.

In a method step 92, the control unit 62 in turn transmits the identifiers 69, 70 (or the information determined therefrom, possibly also with further processing by the control unit 62) by means of the communication 86 to the data memory 63, which is designed in particular as a cloud memory 87 , In the data memory 63, an assignment of the marking 69, 70 or the information determined therefrom to types or components of workpieces that can be processed with the dies 66, 67 assigned to the markings 69, 70 is stored.

In view of this assignment and a communication of the data memory 63 to the control unit 62 and / or the control unit 73, in a method step 93, information about the output device 74 and / or 82 can be brought to the attention of the user. Thus, for example, in the method step 93, the user can be shown via the display of the smartphone with which plugs, which cable and / or which seals can be crimped with the dies 66, 67 inserted in the crimping tool 2.

For example, it is also possible for the user to enter a product or type number of the workpiece or components via the workpiece specification device 84 of the control unit 62, and the control unit 62 indicates to the user that the crimping of that workpiece or its component with the dies 66, 67 is allowed or not. It is also possible for the workpiece specification device 84 to be formed with the camera 1 or a further camera, with a product or type number of the workpiece being identified on the basis of the image generated by the camera 1 by means of the control unit and suitable control logic, or based on the geometry of the workpiece, the type of the workpiece is detected. On this basis, an indication can then also be generated as to whether the detected die 66, 67 is suitable for the type of workpiece recognized.

Optionally and alternatively or cumulatively, it is possible that in a method step 94 of the control unit 62 specific data 98 are provided from the data memory 63 for the detected identifications 69, 70, which are a desired crimp force course 99 and / or a desired value Crimping path 100, slopes thereof, maxima, minima and the like. Ä. Can act. If crimping of a workpiece is then carried out with the crimping tool 2, the actual crimping force signal 76 detected by means of the sensor 68 and / or the actual crimping signal 77 is transmitted from the control unit 73 to the control unit 62 by means of the communication 85. By means of the control unit 62, an evaluation of the crimping process then takes place in a method step 95 Consideration and comparison of the desired Crimpkraftverlaufs 99 and / or the desired Crimpwegverlaufs 100 on the one hand and the actual Crimpkraftsignals 76 and / or the actual Crimpwegsignals 77 on the other. On the one hand, such an evaluation can be used for checking whether there is any permissible use of the inserted dies 66, 67 for the workpiece pressed therein, since a pressing of an unsuitable workpiece (in particular with a non-matching diameter, an inappropriate stiffness and / or or a mismatched geometry) to a deviation of the actual Crimpkraftsignals 76 from the desired Crimpkraftverlauf 99 out of a tolerance range (which can also be provided by the data memory 83 via the communication 86 of the control unit 62). However, even if a permissible workpiece can be crimped with the dies 66, 67, by means of the comparison, a process monitoring can be carried out as to whether the workpiece has been correctly inserted into the dies 66, 67 and the crimping stroke has been carried out properly. If this is not the case, the actual crimp force signal 76 likewise lies outside the tolerance range of the desired crimp force profile 99. A corresponding output can then be generated via the output device 82, that is, for example, an output such that the workpiece for crimping with the dies 66 , 67 was or may not be, the crimp stroke was or has not properly passed, or even an indication of the actual crimp force signal 76 over time or over the desired crimp force profile 99 and / or the actual crimp travel signal 77 over time or over the target -Crimpwegverlauf 100 (possibly also with the representation of the tolerance range), whereby the user is also brought to the knowledge where the actual Crimpkraftsignal 76 has been within the tolerance range and whether under certain circumstances, the tolerance range has been left.

In a method step 96, documentation can then take place in that an entry into a data memory of the crimping tool 2, in particular the electronic component 6 or the identification processing unit 71, into the data memory 83 and / or the data memory 63 takes place. For example, in order to give an example not limiting the invention, the entry in the date of execution of the crimping stroke, the detected marking 69, 70, any information about the workpiece inserted or input via the workpiece specification device 84 or the camera 1 may include data to the result of the evaluation of the crimping process such as the actual Crimpkraftsignal 76 and / or the actual Crimpwegsignal 77 exist. Optionally, by means of the workpiece specification device 84, which is based on the image of a workpiece to be pressed with an image recognition for recognizing the workpiece or the components thereof on the basis of the image of the camera 1 or can be based on a manual digit input, a specification of the workpiece, which is to be crimped with the crimping tool 2 done. This can then also be documented in method step 96 by an entry. It is also possible to then check in the control unit 62 whether the specified workpiece and the dies 66, 67 are an admissible combination, and the result can then be displayed via the output device 82. Alternatively or cumulatively, it is possible for the specified workpiece from the data memory 63 then to be specific for the specific workpiece characteristic data of the control unit 62 (as for the combination dies 66, 67 / specific workpiece specific desired crimping force curves 19 and target Crimpwegverläufe 100) Be made available, which can then be based on the evaluation described above. It is also possible that on the basis of the detected or specified by the workpiece specification device 84 specification of the workpiece to be crimped or on the basis of the recorded on the basis of the camera 1 shot detected workpiece to the user on a display device, which suitable die in the Gesenkaufnahme must be used.

Fig. 12 shows by way of example and schematically a method for crimping a workpiece with a crimping tool network 61:
In a method step 101, a crimping tool 2 is equipped with dies 66, 67 of a designated type.

In a method step 102, the specific die 66, 67 (in particular a unique product number and / or a type of the die 66, 67) is detected, which can be done by the identification processing unit 71 of the crimping tool 2. It is also possible that this is done by means of the camera 1, which detects a corresponding marking of the dies 66, 67 (for example barcode, product number) or the geometry of the die 66, 67 in the die receptacle or outside thereof before being introduced into the die receptacle 64 , 65 recorded. Based on an image recognition can then be determined from the detected geometry of the type of Gesenk 66, 67. This image recognition can be carried out by the electronic control unit 73 of the crimping tool 2 or by the external electronic control unit 62, whereby the control unit 62, 73 can also rely on data (for example geometries of different types, assignment tables, characteristic features of the different types of dies), which are stored in a memory unit of the crimping tool 2, the data memory 83 of the external control unit 62 or the external data memory 63.

In a method step 103, the workpiece to be crimped is brought into the receiving area of the camera 1 and a photograph of the workpiece with the camera 1 is generated.

Based on the recording, the workpiece is then identified in a method step 104. This can be done by means of an image recognition by evaluation of a barcode, a product number of the workpiece or the like by the control unit 73 of the crimping tool 2 or (after transmission of the recording or characteristic characteristics thereof) by the external control unit 62, to which the control unit 62, 73 data which can be stored in a memory unit of the crimping tool 2, the data memory 83 or the external data memory 63. It is also possible that the identification of the workpiece or the type thereof from the recording of the camera 1 by evaluating the geometry by means of image recognition by the control unit 62, 73 can be done, which also by a comparison with in the data memory 83, a data memory of the crimping tool 2 or the external data storage 63 stored geometries or characteristic features can be done.

In a method step 105, the workpiece is inserted into the receptacle formed by the dies 66, 67.

In a method step 106, a check is made as to whether the workpiece has been inserted in the correct position and orientation into the receptacle formed by the dies 66, 67. This can be done by means of a arranged in the region of the dies 66, 67 locators or a contact switch u. Ä. Preferably, this is done by means of a recording generated with the camera 1, wherein also a comparison of the recording with a target recording for the correct position and orientation of the detected type of Gesenk 66, 67 and the recognized type of workpiece can be done and / or a Comparison of the geometry of the recording with the desired recording or characteristic features can be done.

Following this, the crimping process is carried out in a method step 107.

Before or preferably during or after passing through the crimping process, in a method step 108, a photograph is taken by the camera 1 from the workpiece in the of the Dies 66, 67 formed recording. In this case, the recording can be triggered manually by the user via an actuator such as a button or switch, be triggered controlled example. With reaching a closed position of the hand lever 8, 9 or a component driven therefrom, exceeding a threshold value of the measured crimping force or crimping or be triggered automatically upon reaching a characteristic feature of the Crimpkraftverlaufs and / or Crimpwegverlaufs.

In a method step 109, the crimping process is evaluated by evaluating the recording produced by the camera 1. Again, an assessment based on a comparison of the generated by the camera 1 with a nominal recording (or based on derived therefrom characteristic features), wherein the evaluation and / or the provision of the desired recording or the characteristic features by means of Crimping tool 2 with associated control unit 57 and memory unit, the external control unit 62 with associated memory and / or the external data memory 63 can be done.

It is understood that in Fig. 12 specified process steps 101 to 109 can all be passed through or individual of the mentioned process steps can be omitted.

Furthermore, the following method steps can optionally be carried out:
It is possible that it is checked in a method step 110 whether there is an admissible combination with the type of the die 66, 67 identified in the method step 102 and the type of workpiece identified in the method step 104. For this purpose, combinations of permissible types of dies with permissible types of workpieces (and / or non-permissible combinations) can be stored and used in a memory unit of the crimping tool 2, the external control unit 62 and / or the external data memory 63, the evaluation then being carried out by the Control unit of the crimping tool 2 or the external control unit 62 can take place.

It is possible for data to be stored (in particular for documentation purposes) in a method step 111, the storage being able to take place in a memory of the crimping tool 2, a memory assigned to the external control unit 62 or the external data memory 63. In this case, for example, the storage of the die or type of the die identified in the method step 102 can take place, a storage of the in the method step 104 identified workpiece or type of workpiece or storing the result of the test in the method step 110, whether a permissible combination thereof, a storage of the recording of the die and / or the recording of the workpiece, a storage of recording of the inserted into the die workpiece for checking the correct insertion and / or storage of a recording taken during or after the crimping process, a storage of the result of the evaluation of the crimping process in the method step 109, a storage of the result of the correct insertion in the method step 106 u. Ä.

It is also possible that, in a method step 112, data is communicated via the crimping tool network 61 between the crimping tool 2 and / or the external control unit 62 and / or the external data memory 63, which, for example, provides the information, for documentation and to enable the execution of processing steps by control logic of another control unit at a different location.

It is also possible that in a method step 113 an output device 74 of the crimping tool 2 or an external output device 82 generates an output for the user, which is preferably an acoustic and / or optical output. It is possible, for example, for the output in the die 66, 67 or type of die identified in the method step 102, in the workpiece or type of the workpiece identified in the method step 104, in an information determined in the method step 106, to determine whether the workpiece is correctly in the die has been inserted, as a result of the evaluation in the process step 109, whether the crimping process has been properly completed, in a result of the evaluation in the process step 110, if there is an allowable combination of a type of die with a type of a workpiece, and / or in a shot produced by the camera 1.
