- the present invention is also based on the object of providing a system for assembling an electrical cable, which has a device for applying an adhesive strip to a lateral surface of the electrical cable, by means of which the adhesive strip can be applied at least partially automatically and with preferably high process reliability and accuracy .
- the object of the invention is to provide a method by means of which an adhesive strip can be applied to a lateral surface of an object, at least partially automatically and with preferably high process reliability and accuracy. It is also an object of the invention to provide a computer program to carry out an advantageous method for applying an adhesive strip to a lateral surface of an object.
- the object is achieved for the device with the features listed in claim 1. With regard to the system, the object is achieved by the features of claim 30. Regarding the method, the object is achieved by claim 31 and for the computer program by claim 36.
- a device for applying an adhesive strip or fixing tape to a lateral surface of an object.
- the adhesive strip can be, for example, a fabric tape, ie in particular an adhesive strip with a reinforcement made of a fabric, preferably a plastic fabric. Such an adhesive strip can be particularly tear-resistant or robust.
- a PET fabric adhesive tape can be provided particularly advantageously.
- the width of the adhesive strip can be, for example, 1 mm to 20 mm, preferably 2 mm to 10 mm, particularly preferably 3 mm to 7 mm, very particularly preferably 5 mm or less. In principle, however, adhesive strips of any width can be provided.
- the thickness of the adhesive strip can be, for example, 0.1 mm to 5 mm, preferably 0.5 mm to 3 mm, particularly preferably 1 mm to 2 mm. In principle, however, adhesive strips of any thickness can be provided.
- the adhesive strip preferably has only a single adhesive surface or adhesive side. In principle, however, the adhesive strip can also have adhesive surfaces on both sides.
- the adhesive strip (possibly also the supply of adhesive strips mentioned below or the adhesive tape mentioned below) can be understood as part of the device according to the invention when the adhesive strip is inserted into the device.
- the adhesive strip is not necessarily part of the device, particularly not if the adhesive strip is not located in the device.
- the object (and possibly its components) can be understood as part of the device according to the invention when the object is introduced into the device.
- the object is not necessarily part of the device, particularly not if the object is not located in the device.
- the invention is essentially described here for use in exactly one object, it should be emphasized that this does not exclude the invention being used for the simultaneous application of the adhesive strip to two or more objects.
- two or more objects can be placed in the holder mentioned below (or in several holders arranged next to one another).
- the invention can then be used advantageously, for example, to bundle a number of individual objects by applying a common adhesive strip, for example to produce a cable harness from a number of individual cables.
- the following statements can therefore relate to use with more than one object, even if this is not explicitly stated.
- the device according to the invention has a holder for the object.
- the holder can be designed to receive, support and/or guide the object partially or completely.
- the holder can be set up to ensure the correct positioning and orientation of the object in the device.
- the mount can optionally be set up to fix the object axially and/or radially, as a result of which the object can be accommodated in the mount so that it cannot be pulled out and/or cannot be twisted.
- the holder can support a user and/or a delivery device of the device in correctly inserting or aligning and/or positioning the object in the device.
- the holder can only have passive components, but can also be set up to actively guide, position and/or align the object in the device.
- the device has a mounting assembly with a primary mounting means.
- the primary assembly means can be brought along a delivery direction into a working position delivered to the object.
- the fact that the primary assembly means can be brought from the rest position into the working position is to be understood in particular as meaning a relative positioning between the primary assembly means and the object. It can thus be provided that the primary assembly means is actively delivered to the object, that the object is actively delivered to the primary assembly means, or that the primary assembly means and the object are each moved towards one another. This also applies to the delivery of the secondary assembly means described below to the object.
- the primary mounting means can preferably be positioned freely or steplessly between the rest position and the working position. If necessary, however, it can also be provided that the rest position and the working position represent the only stable end positions of the primary assembly center Is. This also applies to the secondary assembly means.
- the device also has a rotation device that is set up to initiate a rotation between the lateral surface of the object accommodated in the holder and the primary assembly center Is.
- the rotation device can be set up to rotate the object and/or the device or its relevant components (e.g. the mounting assembly and the adhesive tape bearing mentioned below, the guide units mentioned below and the holding device mentioned below) jointly rotate around the object or around the holder of the object.
- the device or its relevant components e.g. the mounting assembly and the adhesive tape bearing mentioned below, the guide units mentioned below and the holding device mentioned below
- the primary mounting means is set up to press an adhesive surface of the adhesive strip against the lateral surface of the object held in the holder in the working position.
- the rotation means is configured to initiate rotation while the primary mounting means is in the operative position.
- the adhesive strip can be securely applied to the lateral surface in the pressing area.
- the rotation can then bring further sections of the adhesive strip into the area of influence or pressing of the primary assembly means, which are also securely applied to the lateral surface as a result.
- the proposed device can be automated to a large extent. Due to the high precision of the device or the method, it is also advantageously possible to process adhesive strips of any width and thickness.
- the adhesive strip is positioned between the object held in the holder and the primary installation means when the primary mounting means is in the rest position or runs between the object held in the holder and the primary mounting means.
- the primary mounting means is able to mechanically contact the adhesive strip during delivery from the rest position to the working position and to carry it along on the way in the direction of the object.
- the adhesive strip is then already in contact between the primary assembly means and the lateral surface.
- the adhesive strip can run along a feed direction, starting from a supply of adhesive strips.
- the adhesive strip preferably extends essentially in a straight line along the feed direction, starting from the supply of adhesive strips.
- curved profiles for example curved profiles in sections, can also be provided. Starting from the supply of adhesive strips, the adhesive strip can in principle follow any desired path.
- the adhesive strip preferably runs through the device as an endless band.
- the device has one or more guide units for guiding the adhesive strip.
- the guide units can be designed to keep the adhesive strip taut or to guide it taut as required, particularly in the case of "endless" feeding.
- the guide units can also be designed to predetermine the course of the adhesive strip through the device (in particular along the feed direction) in the first place and/or to prevent it from “running”, i.e. laterally or laterally breaking out of the guide (orthogonal to the feed direction). block and thus always guide the adhesive strip in the intended path.
- the device has a non-driven, freely rotatable adhesive tape mount for receiving an adhesive tape, starting from which the adhesive strip runs.
- the adhesive tape can advantageously form the adhesive strip supply.
- any diameter of the adhesive tape can be used within the scope of the invention.
- any coil size can be provided.
- the use of adhesive tapes with large overall lengths of adhesive strips or large diameters and therefore large stocks can be advantageous in order to increase user-friendliness and reduce the maintenance intervals of the device.
- the adhesive tape bearing can have a brake and/or be mounted with corresponding resistance to move, in order to provide the most taut course of the adhesive strip, starting from the adhesive tape and extending to the object.
- the adhesive tape support can also be designed to provide a constant restoring force in the opposite direction to the dispensing direction in order to keep the adhesive tape taut.
- the adhesive tape storage can also have a drive, for example to tighten or loosen the adhesive strip as required.
- the holder for the object has a receptacle for a front, free end of the object and/or a stop for the front, free end of the object and/or a support for the object.
- the holder for the object can be designed, for example, as a receiving sleeve or bore for receiving the object in order to receive the front, free end of the object.
- An end stop for the free end of the object can optionally be provided within the receiving sleeve or the bore; the bore can thus be designed as a blind hole, for example.
- the object can protrude or be guided completely through the receiving sleeve or the bore; the bore can thus also be formed as a through bore.
- the holder in particular the receiving sleeve, the bore or the support, is preferably positioned close to the processing position of the object by the primary mounting means, ie close to the position at which the adhesive strip is to be applied.
- the bracket is located as close to this position as is technically feasible.
- the rotation device is set up to initiate the rotation in a first direction of rotation and/or in a second direction of rotation opposite to the first direction of rotation.
- the rotation device can also be set up to initiate the rotation in only one direction of rotation. This direction of rotation is then preferably the direction of rotation that leads to the winding of the adhesive strip on the lateral surface.
- the first direction of rotation is preferably a direction of rotation which leads to the adhesive strip, which is initially already partially applied by the primary mounting means, being unwound from the lateral surface.
- the second direction of rotation is preferably a direction of rotation that leads to a further winding of the adhesive strip onto the lateral surface.
- the first direction of rotation is towards the feed direction of the adhesive strip when the mounting means is rotated relative to the object while the object is stationary.
- the second direction of rotation is opposite to the feeding direction of the adhesive strip when the mounting means is rotated relative to the object while the object is stationary. If, on the other hand, the object is rotated while the mounting means is stationary, the directions of rotation are preferably reversed in relation to the feed direction.
- the rotation device is set up to allow rotation initially in the first direction of rotation and then in the second direction of rotation. In this way, when the rotation is first initiated in the first direction of rotation for unwinding the adhesive strip, a free end piece and/or an end region of the adhesive strip can be applied or pressed precisely onto the lateral surface, after which it is then rotated in the second direction of rotation for winding up of the adhesive strip the adhesive strip is wound onto the lateral surface in the intended length.
- the device has a holding device for at least one free end of the adhesive strip adjoining the primary mounting means.
- the holding device can advantageously be used to ensure that the adhesive strip runs from the supply of adhesive strips along the feed direction, in particular in such a way that the adhesive strip runs between the object and the primary mounting means when the primary mounting means is in its rest position.
- the adhesive strip is under tensile stress, starting from the supply of adhesive strips.
- the holding force with which the free end of the adhesive strip is attached to the holding device can be dimensioned in such a way that the free end detaches from the holding device when the primary assembly means is fed into the working position while advancing the adhesive strip in front of it.
- the adhesive strip of the holding device can preferably be removed automatically by the delivery of the primary assembly means into the working position.
- the holding device has a first holding body on which the free end of the adhesive strip rests.
- the free end of the adhesive strip with the adhesive surface preferably rests on the first holding body.
- the first holding body can have a contact surface on which the adhesive strip can advantageously rest, in particular with the adhesive surface.
- the contact surface of the first holding body preferably points away from the object or from the holder for the object.
- the Contact surface of the first holding body facing the primary mounting means when the primary mounting means is in the rest position.
- the first holding body is also moved in the infeed direction during the infeed of the primary assembly means into the working position, preferably synchronously with the primary assembly means.
- the first holding body can contribute to depositing or stripping off the end section of the adhesive strip in a defined manner on the lateral surface of the object.
- the detachment of the adhesive strip from the contact surface of the first holding body can be supported by the movement of the first holding body in the infeed direction.
- the holding device has a second holding body.
- the holding bodies are preferably arranged opposite one another.
- the first holding body and the second holding body can be advanced against one another in order to fix the free end of the adhesive strip between the two holding bodies.
- Fixing the free end of the adhesive strip between the two holding bodies can further increase the holding force within the holding device and thus ensure that the free end of the adhesive strip is not accidentally lost.
- the process reliability and user-friendliness can thus be increased.
- Both holding bodies are preferably deliverable. In principle, however, only the first holding body can be advanced onto the second holding body or the second holding body onto the first holding body.
- first holding body and/or the second holding body have a pressure regulator in order to regulate the contact pressure of the two holding bodies in their state in which they are placed against one another.
- Regulating the contact pressure of the two holding bodies can be advantageous in order to ensure that the free end of the adhesive strip is not fixed too strongly in the holding device or sticks to the first holding body. In particular, it can be ensured that the free end of the adhesive strip can be pulled out of the holding device in a non-destructive manner as part of the delivery of the primary assembly means into the working position.
- the first holding body and/or the second holding body have a structured contact surface (in particular the first holding body) in order to reduce the adhesive effect of the adhesive surface on the contact surface when the adhesive surface of the adhesive strip is on the contact surface rests.
- a structured contact surface for example a jagged contact surface or a contact surface with grooves, can reduce the effective contact surface in connection with the adhesive surface of the adhesive strip, which reduces the adhesive effect of the adhesive strip on the contact surface and thus enables the adhesive effect to be adjusted.
- This can also ensure that the adhesive strip can be removed easily and non-destructively from the holding device as part of the delivery of the primary assembly means into the working position.
- it can be ensured that the adhesive effect of the adhesive surface is not already too prestressed and that the free end of the adhesive strip still provides sufficient adhesive effect for subsequent attachment to the lateral surface.
- the second holding body is fastened to the mounting assembly together with the primary mounting means and is arranged downstream of the primary mounting means along the feed direction of the adhesive strip.
- the first holding body can be designed, for example, in the manner of a web extending from the mounting assembly.
- the second holding body can optionally also be designed in the manner of a web.
- the device has a cutting device.
- the cutting device can be set up to divide the adhesive strip at a defined axial position.
- the cutting device is preferably set up to cut the adhesive strip at the defined axial position in a non-cutting manner. In this way, no particles are introduced during the cutting process that could negatively affect the processing quality or process reliability.
- the cutting device is preferably set up to carry out a pulling cut.
- a cutting device can be particularly advantageous if the adhesive strip is in the form of an endless tape and not already in individual pieces that have already been cut to length.
- the adhesive strip can be automatically cut to length using the cutting device.
- the cutting device has a blade or two blades that can be moved relative to one another.
- the use of two blades that can be moved in opposite directions can be advantageous.
- the two blades can be arranged in the manner of the arms of a pair of scissors in order to shear the adhesive strip between them.
- a cleaning unit can optionally be provided in order to clean the at least one blade of the cutting device upon contact or after contact with the adhesive surface.
- the cleaning unit can have one or more brushes or cleaning belts, for example.
- Thermal cleaning of the blades, for example heating the blades, can also be provided. Cleaning can be performed after each cutting operation, at regular time intervals, after a predetermined number of cutting operations, or as needed.
- the cutting device is set up to score the adhesive strip only starting from one surface or from both surfaces (possibly also from one or both side surfaces) or to weaken its mechanical strength at the cutting position, after which the adhesive strip then or previously initiated tensile stress breaks off at the cutting position. In this way, contact of the blade(s) with the adhesive surface can also be avoided or at least reduced.
- the cutting device can also be set up to thermally and/or chemically cut through the adhesive strip or to thermally and/or chemically weaken its mechanical resilience at the cutting position, after which the adhesive strip tears off at the cutting position as a result of subsequent or previously introduced tensile stress.
- the cutting device may include one or more heated blades, dies, or coils.
- a supply device for chemical substances for example an acid or base, can also be provided.
- Even a targeted cold treatment, for example with liquid nitrogen, can be provided in order to reduce the brittleness and mechanical strength at the cutting position.
- At least one of the blades of the cutting device is arranged on one of the holding bodies of the holding device.
- One of the blades is preferably assigned to each of the holding bodies.
- the cutting device can be advanced on the adhesive strip in order to divide the adhesive strip at the defined axial position.
- the cutting device can preferably be feedable orthogonally or at least substantially orthogonally to the feed direction of the adhesive strip and/or to the feed direction of the primary assembly means.
- the cutting device can preferably be adjusted orthogonally to the feed direction of the adhesive strip and to the infeed direction of the primary assembly center Is, in particular parallel to the course of the longitudinal axis of the object accommodated in the holder.
- the device has a secondary assembly means which, starting from a rest position at a distance from the object accommodated in the holder, can be brought into a working position delivered to the object.
- the secondary mounting means is preferably identical in design to the primary mounting means, although this does not necessarily have to be the case.
- the secondary assembly means as a supplement to the primary assembly means can increase flexibility when processing the object or when applying the adhesive strip. Furthermore, the course of the method can be optimized overall and self-contained as a result, which will also appear below.
- the secondary mounting means is preferably arranged downstream of the primary assembly means along the feed direction.
- the second holding body is fastened to the mounting assembly along the feed direction of the adhesive strip between the primary mounting means and the secondary mounting means.
- the mounting assembly can be adjusted orthogonally to the infeed direction by means of an actuator device in order to selectively position the primary mounting means or the secondary mounting means in the infeed direction above the object accommodated in the holder.
- the primary mounting center Is or the secondary mounting means is positioned such that the mounting means is aligned with the longitudinal axis of the object.
- the adhesive strip can be brought up to the object with particular precision when the assembly means is brought into the working position.
- the mounting assembly can be adjusted by means of the actuator device, in particular along the feed direction or counter to the feed direction of the adhesive strip.
- the actuator device is designed to also adjust the first holding body in a manner that is synchronized or mechanically coupled to the adjustment of the assembly assembly.
- the mounting assembly and the first holding body (together with their respective actuators, eg the linear actuators mentioned below) can be fastened to a common holding plate, for example, which is then adjusted by the actuator device.
- the assembly assembly has a first linear actuator in order to adjust the primary assembly means, the secondary assembly means and/or the second holding body in the infeed direction.
- the entire mounting assembly can preferably be adjusted by means of the first linear actuator, with the primary mounting means, the secondary mounting means and/or the second holding body being correspondingly fastened on the mounting assembly.
- a mechanically coupled delivery of all necessary components can thus take place in an advantageous manner.
- the device has a second linear actuator in order to adjust the first holding body in the infeed direction.
- the first holding body can also advantageously be deliverable.
- rotating drives or other drives can also be provided instead of linear actuators.
- the assembly assembly or the primary assembly means, the secondary assembly means, the first holding body and/or the second holding body can also be delivered along predetermined paths, for example using a magnetic drive and/or a link control.

- a transport device 42 can be provided for transporting the cable 4 between the individual processing modules 38, 39, 40, 41, in particular a transport device 42 with a workpiece carrier 43 which can be moved along a line transport direction T.
- the line transport direction can, for example, correspond to the feed direction x of the adhesive strip.
- a line carrier or cable carrier can be attached to the workpiece carrier 43, on which the cable 4 is held for transport and for processing.
- the line carrier can be moved on the workpiece carrier 43 along a cable feed direction, for example using a rail system (not shown), in order to attach the cable 4 for processing to at least one of the processing tools and/or to at least one of the processing modules 38, 39, 40, 41 or to the device 1.
- the processing tools or the processing modules 38, 39, 40, 41 or the device 1 can also be advanced to the cable 4.
- the system 37 can have, for example, a first processing module 38 for aligning and positioning and optionally for measuring the cable 4 .
- a stripping station (not shown) can then be provided in order to strip a section of the cable jacket 24 and, if necessary, a cable foil arranged under the cable jacket 24 .
- connector components of the connector can optionally already be pushed onto the cable jacket 24 of the cable 4, for example a retaining cap, a cable seal, a housing assembly or a shielding plate, preferably in the sequence required later.
- the support sleeve 25 is preferably crimped onto the cable jacket 24 and/or onto the braided cable shield 23 .
- a third processing module 40 shown as an example, can be provided for folding the free end of the braided cable shield 23 over the support sleeve 25 .
- the braided cable shield 23 can be shortened beforehand or during folding.
- the individual strands of the braided cable shield 23 usually end in different lengths and in a disorderly manner on the cable jacket 24, behind the support sleeve 25.
- a cleaning can in principle be provided at any point in time within the framework of the system 37—possibly also several times.
- the device 1 according to the invention can be advantageously suitable for this purpose.
- a fourth processing module 41 of the device 1 according to the invention is shown below by way of example, which is set up to release the inner conductors from their common filling layer 22 .
- the inner conductors 20 can then be stripped and provided with inner conductor contact elements of the subsequent connector.
- the inner conductor contact elements can preferably be crimped onto the inner conductors 20 . It can then be provided that the inner conductor contact elements are inserted into a contact part carrier and latched to it. Then, for example, a shielding sleeve can be pushed onto the contact part carrier and pressed. Finally, housing assemblies, seals and end caps or other final assembly can be provided for the final assembly of the connector.
