Definitions

  • the present invention relates to a method for machine processing of at least one electrical line.
  • the invention also relates to a device for machine processing of electrical lines.
  • the invention relates to the machine processing of electrical lines using a joining aid.
  • a contact part housing can be, for example, a plug housing or the like.
  • one end of the electrical line has an electrical contact part attached to it, which is then received in the contact part housing.
  • the end of the electrical line has a desired alignment, orientation and / or position in order to be able to be introduced into the contact part housing.
  • the object of the invention is therefore to create an improved possibility for machine processing of electrical lines using means that are structurally as simple as possible.
  • the method can be carried out, for example, with a device for machine processing of electrical lines according to the second aspect below.
  • the method can preferably be carried out in an automated manner, i.e. by a machine.
  • An electrical line can be understood as a strand-like element that consequently has two ends.
  • An electrical contact part can be attached to the first and / or second ends, for example by crimping, etc.
  • it can be a plug-in contact part or the like, with several, i.e. at least two, of these contact parts being a connector with, for example, several pins, or can train something similar.
  • the method can also be applied to the second side in at least a similar or identical manner.
  • the type, configuration, etc. of the contact parts, the joining aid and / or the contact part housing differs from side to side.
  • the joining aid can, for example, have a base body, such as a cuboid, etc., which is open on both sides along a longitudinal axis that is defined by a longitudinal extension of the electrical lines.
  • the joining aid can have two opposite open sides.
  • Two or more cavities, such as contact chambers, etc. can be formed within the base body, which cavities can be designed to accommodate the first end or contact parts attached to it.
  • the cavities can preferably be shaped so that there is a fit, preferably a loose fit, between an inner wall of the respective cavity and the respective first end of the electrical lines in order to prevent the electrical line from rotating about its own longitudinal axis, which, for example, to a change in position, untwisting of previously twisted electrical lines, etc.
  • transferring the first end of the electrical line can be understood to mean that the first end of the electrical line is brought out over the second side of the joining aid and reinserted into the contact part housing, the outfeed and reinsertion overlapping.
  • the electrical line is held by the joining aid, by the contact part housing or by both the joining aid and the contact part housing.
  • the respective electrical line is held during the entire transfer by at least one of the above components, so that the respective electrical line does not change in its position and / or orientation, e.g. does not untwist again after being twisted.
  • the method makes it possible to keep one end of the electrical line in a desired orientation and / or position while the contact part housing is being fitted.
  • the method enables a number of electrical lines to be twisted with one another before the contact part housing is fitted, this twist is maintained and only then the contact part housing can be fitted with the first ends of the electrical lines.
  • electrical lines that are twisted with one another and also untwisted electrical lines that run parallel to them can be attached to a single contact sub-housing.
  • the procedure can be full or automate at least to a comparatively high degree.
  • the joining aid can be reused, which means that the method can be carried out inexpensively.
  • the method can also include: twisting together a first and a second electrical line while the first ends of the electrical lines are held in the joining aid. Accordingly, the first ends of two or more electrical lines can be processed according to the method described here with the aid of the joining aid. The method thus enables the twisting of the lines to be maintained during the transfer into the contact part housing.
  • the first end can be held in the joining aid so that it cannot rotate. This can be achieved, for example, by means of a fit, in particular a clearance fit.
  • the first ends are preferably held in a form-fitting manner, possibly also in a force-fitting manner. This enables the position and / or alignment of the first end to be maintained, in particular in the case of a previously performed twist.
  • the first end can be held in the contact part housing so that it cannot rotate. This can be achieved, for example, by means of a fit, in particular a clearance fit.
  • the first end is preferably held in a form-fitting manner, possibly also in a force-fitting manner. This enables the position and / or alignment of the first end to be maintained, in particular in the case of a previously performed twist.
  • the first end of the electrical line can be held in the joining aid via a fixing device which is set up such that the first end of the electrical line can be moved in a first direction from the first side to the second side of the joining aid and in the opposite, second direction is fixed.
  • the fixing device can form a type of stop or latching in the second direction and thus limit the movement in this direction.
  • the first end of the electrical line can be moved further through the joining aid, but at the same time it can also be prevented from getting out in the other direction.
  • the fixing device can have a locking device on which the first end slide when moving in the first direction and come into engagement with the locking device when moving in the second direction.
  • a locking device on which the first end slide when moving in the first direction and come into engagement with the locking device when moving in the second direction.
  • This can be achieved, for example, by a recess, groove or the like on an inside of the joining aid.
  • the first end of the electrical line, possibly also the contact part optionally attached to it, can have a projection, a nose or the like.
  • the joining aid can form an undercut with the first end of the electrical line and form a clearance fit with the electrical lines adjacent to the first ends. This enables movement along the length of the electrical line. At the same time, this prevents rotation around the longitudinal axis, so that the position and / or alignment, e.g. also a twisting of several lines, is maintained.
  • a gripping device for transferring the first end of the electrical line, can move the electrical lines individually or together along an axis common to the joining aid and the contact part housing.
  • the gripping device can, for example, be designed in the form of tongs and can be controlled electronically. The movement can in particular be translational.
  • the axis can at least substantially correspond to the longitudinal axis of the electrical lines. From a functional point of view, the gripping device can push the first end through the joining aid or out of the joining aid into the contact part housing. This enables a high degree of automation to be achieved.
  • the method can further include: Removal of the joining aid from the electrical line after transferring the first end of the electrical lines into the contact part housing.
  • the joining aid can be slotted on at least one side in order to form an undercut with the first end of the electrical lines, but not with an adjacent section, for example a simple line section.
  • the joining aid can fall off the respective electrical line or be removed manually in a simple manner. This means that the joining aid can be reused.
  • the joining aid can be removed from the electrical line by a gripping device after the first end of the electrical line has been transferred into the contact part housing.
  • the joining aid can be slotted on at least one side in order to form an undercut with the first end of the electrical lines, but not with an adjacent section, e.g. a simple line section.
  • the joining aid can be removed from the respective electrical line by the gripping device. This enables a high degree of automation to be achieved.
  • the joining aid can be reused.
  • the method according to the first aspect can be carried out with the device.
  • the device can be an automatic machine and, if necessary, also part of a tool assembly for cable assembly.
  • the holding devices can be a type of chuck or the like.
  • the twisting device can optionally use the first holding device as a fixing point or for rotation. Twisting devices are otherwise known to the person skilled in the art, so that this is not explained further here.
  • the gripping device can be part of a robot, a linear drive or the like.
  • the device temporarily uses the joining aid to first fix the line end for twisting and then transfer the line ends directly from the joining aid into the contact part housing.
  • Figure 1 shows a schematic side view of a device 100 which is particularly suitable for machine processing of electrical lines.
  • the device 100 is an automatic machine and comprises, for example, a first holding device 110 and a second holding device 120, which are designed here as a type of chuck by way of example.
  • the device 100 has an optional twisting device 130, which is shown here by way of example by two rotatable rotating / clamping devices that are spaced apart from one another.
  • the device 100 has a gripping device 140 which can be moved linearly, for example, by a linear drive or the like, multi-axis, etc.
  • the device 100 can, for example, be operated at least partially automatically by an electronic controller (not shown).
  • two electrical lines 200 are arranged here by way of example, which are intended to be twisted with one another, for example, this being shown in FIG Figure 1 has already taken place and is indicated on the right with a shown stroke of the two lines 200.
  • the device 100 is, however, also suitable for three, four, five or more lines 200.
  • One of the lines 200 is held, for example, by the gripping device 140.
  • Each line 200 has at its first end, which is exemplified in FIG Figure 1
  • the end shown is an electrical contact part 210, which is attached to the respective line 200, for example by means of crimping.
  • the second end of the line 200 can have a similar or identical structure.
  • the contact part 210 is designed here, for example, as a plug contact or pin.
  • the contact part 210 has a fixing element 211 which is designed, for example, for a latching connection with a counter-element.
  • the fixing element 211 is exemplarily designed as a latching projection.
  • the respective contact part 210 is received in a joining aid 300, which is held here by the first holding device 110.
  • the joining aid 300 here has, by way of example, a cuboid body 310 which has an opening 320, 330 on each of two opposite sides.
  • the cuboid body 310 has a number of cavities 340, of which in FIG Figure 1 two are shown as examples.
  • the joining aid 300 can be adapted to the number of lines 200.
  • the Cavity 340 is shaped and / or dimensioned in such a way that there is a fit between an inner side of the same and the contact part 210, which prevents rotation about a longitudinal axis of the contact part 210 or the line 200, but allows movement along the longitudinal axis.
  • This can also be understood as a type of form fit, which holds the contact part 210 so that it cannot rotate but is displaceable.
  • the joining aid 300 has a fixing device 350 in the respective cavity 340, which is designed here as a latching device with a latching projection.
  • the locking projection is aligned such that the first ends of the lines 200 can be moved in a first direction, here the direction from opening 320 to opening 330, and in the opposite, second direction, here the direction from opening 330 to opening 320, are fixed.
  • first direction here the direction from opening 320 to opening 330
  • second direction here the direction from opening 330 to opening 320
  • a contact sub-housing 400 is arranged in the device 100 and is held here by the second holding device 120. In relation to the first direction defined above, the contact sub-housing 400 is arranged downstream of the joining aid 300.
  • the contact part housing 400 has a number of cavities 410 for receiving the first ends of the lines 200, in particular the contact part 210 arranged thereon, each of which has an opening 420 on the side facing the joining aid 300.
  • the respective cavity 410 is preferably aligned with the associated cavity 340 of the joining aid 300.
  • the contact part 210 can likewise be fastened via its fixing element 211, for example.
  • twisting device 130 is set up in particular to be attached directly to the joining aid 300.
  • FIG 1 the contact part housing 400 between the joining aid 300 and the (in Figure 1 left) twisting device 130 is shown.
  • the first end of the line 200 is first introduced into the joining aid 300 from a first side of the joining aid 300, that is to say here via the opening 320.
  • the contact part 210 is already attached to the line 200.
  • the line 200 can be moved, for example, by the gripping device 140.
  • the joining aid 300 can be held in position by the first holding device 110.
  • the fixing element 211 of the contact part 210 is latched onto the fixing device 350 and is thus held in the joining aid 300.
  • the lines 200 held in the joining aid 300 are then twisted with one another by the twisting device 130.
  • the twisting device 130 can be attached directly or indirectly to the joining aid 300, encompassing it, if necessary, or the like. Due to the latching between the fixing element 211 and the fixing device 350, the lines 200 are fixed on both sides and can be twisted together by the twisting device.
  • the first ends of the twisted-together lines 200 are then transferred from a second side of the joining aid 300 that is different from the first side, that is to say via the opening 330, into the contact part housing 400.
  • the joining aid 300 is held, for example, by the first holding device 110.
  • the contact sub-housing 400 is held, for example, by the second holding device 120.
  • the line 200 to be transferred is moved, for example, by the gripping device 140 in the direction of the contact part housing 400.
  • the contact part 210 is still in the joining aid 300 and is transferred from there.
  • FIG. 5 now shows the first end of the line 200 transferred into the contact part housing 400.
  • the contact part 210 is only received in the corresponding cavity 410 of the contact part housing 400 and latches there, for example.
  • the lines 200 are therefore always held in a rotationally secure manner by the joining aid 300 and / or the contact part housing 400, so that the twisting of the lines 200 is maintained.
  • the joining aid 300 can be removed since the first ends of the lines 200 form an undercut and, adjacent to the first ends, form a loose fit with the electrical lines 200.
  • the joining aid 300 can be removed by automatically falling off, manually removing it, or by removing it by means of the gripping device 140.
