Description

[0001] The present invention relates to a method and a device for aligning pre-assembled cable ends of a cable harness, in particular a twisted cable harness comprising several or at least two cables, in the correct rotational orientation. The invention further relates to a cable assembly device for mounting connector housings with pre-assembled cable ends of a cable harness consisting of several cables, wherein the cable assembly device includes such an alignment device for aligning the pre-assembled cable ends in the correct rotational orientation relative to the connector housings to be mounted.

[0002] Wiring harnesses, such as those used in automobiles or aircraft, consist of several cables whose pre-assembled cable ends are fitted with so-called connector housings, a process generally referred to as connector assembly. For this, the previously assembled cable ends – i.e., cut to length, stripped, and fitted with contacts – are inserted into the chambers or receptacles of the connector housings.

[0003] Typically, the cables of a wiring harness, including the cable ends to be fitted, are supplied individually and are inserted into the compartments of the connector housings using appropriate machinery. Increasingly, wiring harnesses are now also being used with twisted cable strands consisting of several individual cables – primarily twisted pairs – which also require fitting the free, especially untwisted or straightened, cable ends of the strand. Twisted pairs are manufactured on cable processing machines – for example, as described in EP 1 032 095 A1 – by twisting the two cables of the pair together after assembly, i.e., after cutting to length, stripping, and crimping the contacts. In principle, such twisted pairs can also be manufactured by fitting the free cable ends of an already twisted pair.For this purpose, the cable pair is deflected on a suitable cable processing machine, the cable ends are untwisted at the ends of the cable pair, stretched and then fully assembled (stripping and crimping of contact parts).

[0004] However, when subsequently populating a connector housing with multiple pre-assembled, free cable ends at one end of the cable harness, a problem arises: it cannot be guaranteed that the contacts at the cable ends are in the required rotational / angular position relative to the chambers of the connector housing. This problem occurs particularly with twisted cable harnesses, but also with other cable harnesses consisting of multiple cables that are bundled together in some way. Incorrect positioning of the cable ends or contacts at the cable ends is detrimental to the assembly process, for example, when a contact with a rectangular cross-section is supposed to fit into a connector housing with a rectangular chamber. Ideally, the cable ends must be aligned as precisely as possible in terms of rotation to ensure successful assembly.

[0005] From EP 1 429 430 A2, a device is known which can transfer pre-assembled cable ends of a single cable into the correct angular position with respect to a housing chamber to be populated. However, this solution described therein for single cables cannot be technically applied to cable strands, in particular twisted cable strands, with several cables in order to individually correct the rotation of the contacts relative to each other at the cable ends.

[0006] The object of the present invention is therefore to provide a method and a device with which the assembled cable ends of a cable strand, in particular a twisted one, consisting of at least two or more cables, can each be individually aligned in a specific desired rotational position.

[0007] This problem is solved by the method according to claim 1 and the apparatus according to claim 5. Advantageous embodiments of the invention are the subject of the dependent claims.

[0008] The inventive method for aligning the assembled cable ends of a cable strand, in particular a twisted one consisting of at least two cables, in the correct rotational position is characterized by the following steps: a. Rotating the entire cable bundle consisting of at least two cables at a section of the cable bundle adjoining the cable ends, in particular a twisted section, to align the free, in particular untwisted, cable end of one of the at least two cables to be aligned into a predetermined desired rotational position with respect to its longitudinal axis, wherein at least the cable end of the cable to be aligned is freely rotatable during the rotation of the cable bundle; b. Holding the aligned cable in its desired rotational position at a section of its free, in particular untwisted, cable end; c. Repeating steps a. and b. for each further cable of the cable bundle to be aligned, wherein each already aligned cable remains held in its desired rotational position at a section of its free, in particular untwisted, cable end.

[0009] The core of the invention thus consists in aligning the assembled free, in particular untwisted, cable ends at one end of the cable bundle in the correct rotational position by rotating the entire cable bundle at a section adjacent to the cable ends for each cable or cable end to be aligned individually and successively until the respective cable or cable end to be aligned has reached its desired rotational position, and then fixing or holding the aligned cable or cable end at a section of its cable end after reaching its desired rotational position, whereby each already aligned cable remains held in its desired rotational position at a section of its free, in particular untwisted, cable end.

[0010] In the context of the present invention, the cable ends of the cable harness to be aligned are those cable ends located at one end of the cable harness. Furthermore, in the context of the present invention, the cable ends to be aligned at one end of the cable harness should be free, i.e., the connection of the cable harness, such as a twist, is released in the region of the cable ends to be aligned, so that, for example, in the case of an otherwise twisted cable harness, the cable ends or the cable harness in the region of the cable ends are untwisted and preferably also straightened. In the context of the present invention, however, the cable ends should in any case be "free" to the extent that they are substantially separated from one another, can be grasped independently of one another, and can be moved relative to each other, at least within a certain range, and in particular twisted relative to each other.If the cable ends to be aligned according to the invention are not yet free from each other, an advantageous embodiment of the invention may provide for "freeing" the cable ends accordingly before alignment, for example by untwisting them, or by dissolving the cable bundle (the connection of the cable bundle, for example by twisting the cable bundle) in the area of ​​the cable ends to be aligned, for example by untwisting them.

[0011] According to an advantageous embodiment of the invention, each unaligned cable can be held at a section of its free, particularly untwisted, cable end while the cable bundle is rotated to align the assembled cable end of another cable. This advantageously ensures that the free, particularly untwisted, cable ends of the unaligned cables do not impede the alignment process or the rotation of the entire cable bundle. Likewise, rotating the entire cable bundle is facilitated, since it is now held in a stabilizing manner at two spaced-apart sections: the "bound" section of the cable bundle and, at its ends, the sections of the free, particularly untwisted, cable ends of the unaligned cables.

[0012] According to a further advantageous embodiment of the invention, the actual rotational position of the cable end of at least one, in particular each, cable to be aligned is detected before and / or during the rotation of the cable bundle. This makes it possible, on the one hand, to determine the angle and direction of rotation before rotating the entire cable bundle to align a specific cable end. Furthermore, by detecting the actual rotational position during the rotation of the cable bundle, the alignment process can be controlled.

[0013] Furthermore, according to a further embodiment of the invention, the free, in particular untwisted, cable end of at least one, in particular each, cable to be aligned is rotatably guided while the cable bundle is rotated to align the respective cable end. This advantageously ensures that the axis of rotation of the cable end to be aligned is clearly defined by a preferably positive-locking guide or at least partial radial enclosure, thereby further stabilizing the rotation of the cable bundle or the alignment of the cable end in question. Moreover, a precisely defined axis of rotation for the rotation or alignment of the cable end significantly improves the detection of the actual rotational position.

[0014] The object of the present invention is further achieved by the following device for aligning pre-assembled cable ends of a cable bundle, particularly a twisted one with at least two cables, in the correct rotational position. This device is particularly suitable for carrying out the previously described inventive method. The inventive device comprises a rotary gripping device for gripping the entire cable bundle at a section of the cable bundle adjoining the cable ends and for rotating the entire cable bundle about its longitudinal axis. The rotary gripping device can, for example, be designed like the rotary gripping device disclosed in EP 1 429 430 A2, in order to grip and rotate the entire cable bundle instead of a single cable – as in EP 1 429 430 A2 – with the aim of rotating each cable or cable end to be aligned individually one after the other until the respective cable or cable end to be aligned is in the correct position.The cable end has reached its intended rotational position.

[0015] To subsequently hold each aligned cable or cable end after reaching its target rotation position, or each already aligned cable or cable end, the device according to the invention has a separate cable gripper for each of the at least two cables for releasable gripping, in particular holding the cable to a section of its free, especially untwisted, cable end. For cable strands with more than two cable ends to be processed, correspondingly more than two cable grippers are provided, i.e., one cable gripper for each cable end.

[0016] According to an advantageous embodiment of the invention, it can be provided that at least one of the cable grippers, preferably all cable grippers, has at least one pair of gripping jaws that are adjustable relative to each other and correspond to each other, which can be moved into a closed position for clamping and holding a cable end, into an open position for picking up and releasing a cable end and preferably also into an intermediate position for at least partially radially enclosing and guiding a cable end along its longitudinal cable axis.

[0017] Furthermore, it can be provided that the gripping jaws of the at least one cable gripper are designed in such a way as to additionally receive the cable end of at least one further cable and, in the closed position and preferably also in the intermediate position, to at least partially enclose it radially and guide it along its longitudinal cable axis.

[0018] To grip, partially encircle, or guide the respective cable ends, the gripping jaws can each have corresponding gripping and / or receiving recesses. For example, the gripping jaws could be designed similarly to the jaws of pliers. To hold a cable end in the closed position, the gripping or receiving recesses can have a roughened or serrated surface. In contrast, the recesses or those areas of the gripping jaws that serve only to radially encircle and guide an additional cable end can have a smooth surface.

[0019] In order to achieve a particularly compact design of the alignment device, it can also be provided that the rotary gripping device and the at least two cable grippers are arranged one behind the other in the longitudinal direction of a cable strand to be aligned by means of the alignment device, in such a way that the at least two cable grippers can each grip one behind the other in the axial direction of the cable strand on a free, in particular untwisted or stretched end region of the cable strand and the rotary gripping device on a section of the cable strand adjoining the free end region, in particular a twisted section.

[0020] To equip the alignment device with a cable bundle to be aligned or processed, an advantageous embodiment of the invention provides that the cable bundle is first inserted into the rotary gripping device. Depending on the feed direction of the cable bundle into the rotary gripping device, particularly if this occurs transversely, and especially perpendicularly to the longitudinal direction of the cable bundle, it can be provided that at least one of the at least two, preferably all, cable grippers can be fed transversely, and especially perpendicularly to the longitudinal direction of a cable bundle to be aligned, to the respective cable end. The feeding of the at least one or all cable grippers can be effected by a suitable, preferably actuator-driven, feeding device.

[0021] Analogous to the method, the device according to the invention may further include a detection device for capturing the current rotational position of the assembled cable ends. According to an advantageous embodiment of the invention, the detection device for capturing and determining the current rotational position of the assembled cable ends may comprise a digital camera or an optical projection sensor. Furthermore, the detection device may include a lighting device for illuminating or generating a projection image. In addition, the detection device may also include an image evaluation device, such as a computer-based image evaluation device in which corresponding image evaluation software is implemented, which serves to determine the current rotational position of the assembled cable end from the captured image of the cable end or the projection image of the cable end.Such detection devices are generally known from the prior art, for example from EP 1 429 430 A2.

[0022] According to a further advantageous embodiment of the invention, at least parts of the detection device, in particular the digital camera or the projection sensor, can be arranged on the front face or radially laterally in the area of ​​the cable ends to be aligned. Such an arrangement allows for a particularly reliable and accurate detection and determination of the respective actual rotational position of the assembled cable ends.

[0023] To control, preferably regulate, the alignment process, the device may further have a control unit which is preferably operatively connected to the rotary gripping device, the at least two cable grippers and the detection device for the controlled, in particular regulated, alignment of the assembled cable ends into the respective target rotation position.

[0024] The invention further relates to a cable assembly device for fitting connector housings with pre-assembled cable ends of a cable strand, in particular a twisted strand of several cables, wherein the cable assembly device has at least one alignment device according to the invention for aligning the pre-assembled cable ends in the correct rotational position with respect to the connector housings to be fitted.

[0025] Further objectives, advantages and possible applications of the present invention will become apparent from the following description of an exemplary embodiment of the invention and from the accompanying figures.

[0026] They show: Fig. 1a-b Perspective view of a possible embodiment of the alignment device according to the invention; Fig. 2a-b Detail view of the rotary gripping device of the exemplary alignment device according to Fig. 1a ; Fig. 3a-d Detail front view of the cable grippers of the exemplary alignment device according to Fig. 1a ; Fig. 4a-c Illustration of a possible embodiment of the method according to the invention using the exemplary alignment device according to Fig. 1a .

[0027] The Fig. 1a-b , 2a-b as well as 3a-d Figure 1 shows a possible embodiment of an alignment device 1 according to the invention for aligning pre-assembled cable ends 111, 121 of a twisted cable bundle 100, consisting of two cables 110, 210, in the correct rotational position. The device 1 is particularly suitable for carrying out the method according to the invention. The device 1 consists of a rotary gripping device 30 in the form of a swivel gripper, which can grip and swivel the twisted cable pair 100. Furthermore, the alignment device 1 comprises two separate cable grippers 10, 20 for releasable gripping, in particular holding the stretched or untwisted cable ends 111, 121 of the cable pair 100. To detect and determine the respective actual rotational position of the assembled cable ends 111, 121, the device 1 also comprises a digital camera 40 with an associated lighting device and an image evaluation device (not shown here).

[0028] The Fig. 2a and b Figure 1 shows details of the embodiment of the rotary gripping device 30, which is implemented in the present form of a swivel gripper 30, as known, for example, from EP 1 429 430 A2. The housing 31 of the swivel gripper 30 has a toothed section 31.1 on its circumference, by means of which it can be continuously rotated by means of a pinion 32. The pinion 32 is driven by a toothed belt 33 by means of a swivel motor 34 (see Figure 1). Fig. 1a and 1bThe housing 31 rests on two support rollers 35, 36 at both its front and rear sides and is held by a counter roller 37 such that only a guided pivoting movement about the central axis of the toothed housing 31 is possible. Integrated into the housing 31 is a pneumatic drive / actuator that can close two gripping jaws 38, 39 centrally. To allow the cable pair to be inserted into the pivoting gripper or rotary gripping device, the circumferentially toothed housing 31 has a wedge-shaped cutout at one point. Fig. 2a shows a possible rotary gripping position in which the cable pair 100 can be inserted horizontally into the rotary gripping device 30. In contrast, shows Fig. 2b The rotary gripping device 30 or the swivel gripper 30, after it has been swivelled 90° clockwise and the gripping jaws 38, 39 have been closed. Further details of the rotary gripping device 30 can be found in the aforementioned EP 1 429 430 A2.

[0029] The two cable grippers 10, 20 are arranged one behind the other in front of the rotary gripper device 30 or the swivel gripper 30, as is shown in particular Fig. 1a and 1b This can be seen from the following. In the event that the cable pair 100 is inserted horizontally into the alignment device 1 (see below). Fig. 2a ), the cable grippers 10, 20 can additionally be lowered together transversely to the longitudinal axis L of the cable string or cable pair 100.

[0030] The Fig. 3a-d further details of the two cable grippers 10, 20 are shown. Each of the cable grippers 10, 20 has two gripping jaws 11, 12; 21, 22, which are designed such that in a closed position (closing position) of the cable gripper 10, 20 they clamp one cable end 111, 121 and merely enclose the second cable end 121, 111 and guide it positively along its longitudinal cable axis L. Fig. 3a Figure 1 shows the first cable gripper 10 in the closed position (closing position), whereby the lower cable end 111 is clamped, while the upper cable end 121 is merely guided axially. Fig. 3b shows the second cable gripper 20, whose gripping jaws 21, 22 are designed such that the upper cable end 121 is clamped, while the lower cable end 111 is only guided axially. Fig. 3d Figure 1 shows, by way of example, the second cable gripper 20 in the open position, which serves to pick up and release the two cable ends 111, 121. In addition to the open and closed positions, the two cable grippers 10, 20 can also be moved into a third position, the so-called intermediate position, in which the gripping jaws 11, 12; 21, 22 are only slightly open in order to at least partially enclose the cable ends 111, 121 radially and guide them along the longitudinal axis of the cable. Fig. 3c Figure 1 shows, by way of example, the second cable gripper 20 in this intermediate position, in which neither of the cables 110, 120 or cable ends 111, 121 is clamped, but rather guided in an enclosing manner, so that both cable ends 111, 121 can be rotated about their respective longitudinal axis L, while simultaneously remaining trapped between the gripping jaws 21, 22. The embodiment of the two cable grippers 10, 20 shown here can be implemented, for example, with a pneumatically actuated three-position gripper or a hybrid gripper such as that known from EP 2 317 613 A1.

[0031] The in Fig. 1a The detection device 40 shown comprises a digital camera 41 with integrated illumination and an image evaluation unit. The digital camera sends its images to the image evaluation unit, which communicates with a controller (not shown here) of the alignment device 1. The image evaluation unit is responsible for determining the angular position of the two assembled cable ends 111, 121, in particular the contacts 113, 123 attached thereto, relative to a reference direction, for example, the horizontal. From this angular position, it is then possible to determine by what amount and in which direction the two contacts 113, 123 must be rotated to achieve the desired target rotation position for assembly. Preferably, the control unit determines the direction of rotation and the amount of rotation.

[0032] Depending on the design, it may be possible to use a simpler optical projection sensor instead of the digital camera 40 for some contacts. For example, with a flat contact with a rectangular cross-section, the angular position of the contact could be determined from the width of the shadow image on the sensor using a line sensor. For this purpose, the line sensor can preferably be arranged transversely to the longitudinal axis L of the cable. However, the digital camera 40 shown in the present embodiment represents the most flexible solution, which can be used universally for different contacts. Preferably, the digital camera 40 is arranged – as shown in the present embodiment – ​​at the end faces of the cable ends 111, 121 to be aligned.

[0033] The following will be used as an example to illustrate the Fig. 4a-c A possible embodiment of the alignment method according to the invention is explained using the previously described embodiment of the alignment device 1 according to the invention. First, the cable pair 100 with the cable ends 111, 121 to be aligned is inserted into the rotary gripper 30 or the swivel gripper 30 in the area of ​​the twisted section adjacent to the cable ends 111, 121 (see figure). Fig. 2a ) and then rotated 90° into the starting position ( Fig. 2b After the cable pair 100 is inserted, an alignment process is carried out separately with each of the two cables 110, 120, if necessary. In the embodiment shown here, however, the contact 113 at the cable end 111 of cable 110 already has a sufficiently accurate angular position, so that only the rotation of the contacts 113, 123 relative to each other needs to be corrected. For this purpose, it is sufficient to carry out the alignment process according to the invention only with the other cable end 121 of cable 120, which is not yet oriented in the correct rotational position.

[0034] Preferably, the process is controlled or regulated. The control or regulation of the alignment process is carried out – as described above – based on the angular position of contacts 113, 123, as captured by the digital camera 40 and determined by the image processing unit. For this purpose, a comparison is made with stored target values ​​for the position of contacts 113, 123, their permissible deviation, and the permissible rotation. Based on this comparison, the control unit determines the angular correction to be performed for each cable end 111, 121, or in this case, only for the single cable end 121.

[0035] In the Fig. 4a-c The alignment process for the cable end 121 located at the top is shown. The cable end 111 located at the bottom remains clamped in the first cable gripper 20, since the cable end 111 at the bottom, or rather the contact element 113, 123 attached to it, is already in a sufficiently precise angular position with respect to its target rotational position, as explained above. Accordingly, in the first step (see Figure 1) Fig. 4a ) the first cable gripper 10 and the rotary gripping device 30 are closed. Then the second cable gripper 20 is moved at least to the intermediate position ( Fig. 4b ) opened to allow free rotation of the upper cable end 121. Alternatively, the second cable gripper 20 could also be opened to the open position, since the upper cable end 121 to be aligned is already guided freely rotatably in the closed position of the first cable gripper 10 ( Fig. 3a and Fig. 4a ).

[0036] To align the upper cable end 121, the twisted cable pair 100 is rotated in the next step using the swivel gripper 30, causing the free, upper cable end 121 to also rotate. Since the cable end 121 does not necessarily rotate by the same angle as the swivel gripper 30 or the rotary gripper 30, the final position of the upper cable end 121 must be checked by the control system using the detection device 40 and corrected if necessary. Ideally, this can be performed during the rotation of the rotary gripper 30 as part of a control process. Once the correct actual rotational position is reached, the second cable gripper 20 is also closed to fix the upper cable end 121 in the desired actual rotational position. This completes the alignment process for both cable ends 111 and 121.
