Apparatus for wiring connection places of components of electrical devices or installations

The invention relates to an apparatus for wiring electrical connection points of components Plant or equipment, according to the preamble of the Claim 1.

according to a known device DE 44 31 254 A1, from which the invention proceeds is especially provided for this purpose, complex wired Lights like fluorescent lamps to be wired automatically.

In the known device the contact each stripped conductor pin ends near the end region of the line-laying means associated conductor laying head the device side of this from to are detected before the outlet opening of a gripper to. Is a first, 'front' conductor insertion end housed in a connection point, and retained therein, moves along the conductor laying head the corresponding traverse its shared conductor length to the next connection point until the gripper the second, 'rear' conductor insertion end in the way has detected that it is in this second connection point can be placed.

For this purpose, the entire device can also the Longitudinal axis of the gripper about an axis of the grasped Conductor insertion end vertical axis are rotated. The following 'third' conductor terminal end, which comprises 'First' of the second made-conductor length, is inside the head of the laying head near the head of the outlet mouth kept to later, after a small feed path, to be able to be detected by the gripper.

According to the mentioned in DE 44 31 254 A1 Intended use, thus the conductor pin ends in Principle within the X / Y-plane (which at a Light, for example, to the bottom of the lamp housing lie parallel) can be plugged into any direction. In other words, there are all the wire insertion directions parallel to a main plane of the the (narrow) end face of the head of the laying head parallel.

It follows that the insertion of conductors shanks in directions oblique or perpendicular illustrated in the DE 44 31 254 A1 be run plug-in directions, only effected could be that the conductor laying head, which is preferably at the Arm of arranged up to six-axis robot, is pivoted correspondingly inclined or up to 90 °. This will basically there existing possibility However, their significant limitation due to the predetermined spatial relationships that exist in all not allow rule that the conductor laying head covering ground is pivoted into the wiring box.

The present invention is derived therefrom in essentially the task from an apparatus for wiring electrical connection points of components to provide equipment or systems, with a simple Art, especially without complicated control or movement of the head of the laying head, pipe connections can be executed automatically without any problems, in which the conductor-insertion not exclusively only substantially parallel to the mounting plane the component runs.

The invention solves this problem with the features of claim 1 and is accordingly substantially characterized in that the outlet mouth for leading end side of the conductor laying head arranged and assigned to a manager turning device is, by means of which the insertion direction of each conductor insertion end regardless of the position of the head of the laying head is required, orientable.

A very important advantage of the invention is firstly that the conductor laying head the Line or the stripped conductor end not for a (Wide) side gives out, but little of its Space-demanding face. To nevertheless without costly Control movements of the head of the laying head held ready conductor insertion end in different be able to position directions, according the invention, the state reversing device is provided.

Of particular importance is the state reversing device in connection with the provision of each second or 'back' conductor insertion end of an on Length made-conductor for connecting two successive connection points to. Because of Invention underlying pipe laying technique accordingly DE 44 31 254 A1 generated after severing the line in the region of a previously stripped Section except for the 'third', with the stripped End of the exit orifice pointing conductor insertion end and the 'second' stripped end of the previously prefabricated conductor specific length. This conductor insertion end but has initially quasi into Inside the head of the laying head and can now by simply Adjusting or turning the state reversing device inside the conductor laying head and independently of its position or control in a new Insertion are oriented. Thus, in a simple Manner also after disconnecting the line still located in the head of laying head second conductor insertion end the next to be equipped junction in the conditions adapted insertion be assigned.

In particular, it is by the means of the invention, easily possible to approach succession terminals, which the conductor shanks all from the same Direction are supplied. Such conditions are present for example when wiring Terminals in electrical cabinet. This date in elaborate manner carried out manually wirings can now according to the present invention are made automatically.

Of course, the invention is not limited to a Turning printed circuit shanks in terms of wire reversal limited by 180 °; Rather it is also thought that the state reversing device each Conductor insertion end in accordance with the present circumstances can orient, so depending on the requirements of the respective connection point, and taking into account a possible tax and Movement optimization of the conductor laying head.

Further advantageous embodiments and expedient Further developments of the invention are defined in the subclaims indicated.

The invention is concerned with using particular robot-controlled wire transfer means 10 Pads 11, 11 'of electrical components to wire devices or systems automatically.

The pipe-laying means 10 is not of a Line stock shown an electrical line 12 is supplied, which is also not shown in a stripped stripping station in precalculated distances Portions received. 13 The prepared Line 12 is by means of a carriage 14, eg a conveyor belt drive, a ladder laying head 15 fed to a certain extent the outer and free marked the end of the line-laying means 10th

The head laying head 15 or more generally the Pipe-laying means 10 is later to descriptive separator 16 for the line 12 assigned. The end face of the head of the laying head 15 has this an opening 17 as a conductor outlet opening on. From this line exit opening 17 donate Placement means 10 or the conductor laying head 15 a designated 18-conductor insertion end which a stripped free end portion 19 and a still having insulation covering 20 provided section. For automatic wiring of terminals 11, the junction 11 and the line-laying means 10 is positioned to one another such that: - As FIG. 1 shows this - the conductor insertion end 18 in the terminal 11 - in longitudinal direction of the conductor insertion end 18 - can be introduced.

The connection point 11 is in the described here Embodiment of the terminal contact 21 of an electric Component, referred to herein as terminal 22 is executed.

Starting from Fig. 1, corresponding to the conductor laying head 15 a to be connected to a connection point 11 Conductor insertion end 18 holds, is this by advancing the head of the laying head 15 to Connection point 11 electrically and mechanically by plugging the conductor end 18 into the screwless terminal contact 21 of the terminal 22 is made.

Thereafter, the line-laying means 10 process with the conductor laying head 15 along a by arrow 23 in Fig. 2 schematically indicated traverse to a further connection point 11 ', located at a distance away from a the first connection point 11 is located (see FIG. Fig. 3). This distance a corresponds substantially the length of the conductor section 24, of the Pipe-laying means 10 will be donated, while the Placement means to the conductor laying head to the next junction 11 'drive.

Around the same time of the distance a corresponding the first conductor insertion end 18 away stripped Section 13 in the region of the line separator 16 passes. The line separator 16 cut line 12 in the middle of this stripped Section 13, thus creating the 'second' stripped end 19 'of the first made-conductor 24 as well as the 'first' stripped end 19 '' of the following, still completely in the line-laying means located 10, initially only partially prefabricated conductor 24 '.

This state is shown in FIG. 3, which is remarkable is that the 'second' stripped end portion 19 ' the line 24 into the interior of the line-laying means or the head of the laying head 15 has and in this Position not easily to be plugged into a is connection point available.

According to the invention, is now the head of the outlet mouth designated part of a 17 to 25 State reversing device. This described in detail hereinafter State reversing device yet described 25 can, as shown by the rotation arrow in Fig. 4, the previously still publishing head internal conductor portion as rotate, that the stripped end 19 'of a second in the Junction 11 'to be inserted conductor insertion end 18 'is released (Fig. 4).

Once in the second connecting point 11 ' Housed conductor insertion end 18 'of the ready-made Conductor 24 is housed, the conductor may be 24 - as described below - from the state reversing device 25 released, so that now successively the next two junctions (Again, corresponding to 11 and 11 ') wired analog can be.

As much it should be noted first that the in each case one connection point 11 or 11 'einzusteckende Conductor insertion end 18 or 18 'from the slim front side of the head of the laying head 15, when Illustrated embodiment, therefore longitudinally the wire transfer means 10 of the overall device exit and not, as in the prior art, the side on the wide side of the device 10. To establish furthermore, that the state reversing device 15 not - As explained with reference to Figs 1-4 -. A complete must perform "turn" of 180 °, but that it is of course also possible, the rotating movement according to arrow 26 to other angular dimensions set so that the conductor insertion end 18 ', for example, obliquely or with respect to the drawing horizontally could be oriented.

The further Figs. 5 to 10 also show schematically further details of construction of the ladder laying head 15. In Fig. 5, the line 12 is omitted and only 'symbolized by its longitudinal central axis 12th One recognizes the better a guide channel 27 within the separator 16. The outlet opening 27 'of this channel 27 forms a movable cutting edge and cooperates with a fixed counter-knife 28 together when the channel 27 by means of a pneumatic Cylinder 29 pivotally in the direction of arrow 30 is actuated.

Respect to the conveying direction (arrow 12 '' in Fig. 5) the line 12 located downstream the already mentioned conductor outlet opening 17 as part of the State reversing direction 25th

As shown in FIGS. 7 to 10 illustrate in greater detail comprises the state reversing device 25 a in the conductor laying head 15 mounted rotating piece 31, whose axis of rotation with designated 32nd This axis of rotation 32 passes visible 5 perpendicular with 12 '' referred to in FIG. Line feed direction within the line-laying means 10, but on the other hand parallel to the through the conductor outlet opening 17 defined plane.

With 33 schematically a gear train, in particular Gear type transmission, to which the schematically designated 34 rotary drive to the rotary motion the rotary part is transmitted 31st

The rotating piece 31 has a to its axis of rotation 32 vertically extending wire management channel 35, which, as Fig. 10 this shows a prismatic cross-section and whose depth is dimensioned such that Usually the dates recorded in his line 12 with its insulation covering 20 or from the prismatic Groove 35 protrudes.

The wire management channel 35 of the rotary part 31 is a clamp body assigned 36 or upstream, of the the embodiment of a fixed cheek Head of the laying head 15 is. As shown in Fig. 6 by dotted indicated lines, the leaves the Rotary piece 31, the gear 33 and the drive 34 comprehensive state reversing device 25 about a horizontal Axis 37 by means of a particular pneumatic Drive 38 pivot. This allows the distance of the Rotary piece 31 of the ladder-publishing head-fixed clamp body-cheek learn 36 different settings.

A first position, the clamping position, characterized in that the ladder turning device 25 at the shortest distance from the clamp body 36 having, so that the line 12 in the prismatic guide groove 35 is held clamped. A second position by an increased distance approximately in the in Fig. 10 in the configuration illustrated, in which the Line 12, of the prismatic guide 35 performed in the latter is displaced longitudinally. A third significant position is the furthest distance by Rotary part 31 given by the clamp body 36, such that the line from the area between these parts 31 and 36 can come free.

The first of the three mentioned positions which Clamping position, is set when - as in FIG. 1 is shown - the first conductor insertion end 18 a Junction 11 is supplied, during turning by means of the turning device 25, or even if, as shown in Fig. 9, the second shank 18 ' after turning a 'second' junction 11 ' to be supplied.

The second, so-called head of leadership, is then taken when the conductor laying head 15 after accommodating the first stripped conductor insertion end 18 in the first connection point 11 with simultaneous donation of the corresponding line length proceed to the second connection point 11 ' (Fig. 2 and 3), while the third, the release position, is then switched and adjusted when the conductors 24 in the respective second connecting point 11 ' (Fig. 4) is housed, and it comes to this now with his two stripped ends in Pads 11, 11 'accommodated release manager and again take the starting position.

It should again be noted that on the basis of Embodiment, a turning process with respect to the illustrated second stripped conductor insertion end 180 ° is, namely in connection with the actual Apply the second or rear conductor insertion end the conductor 24. By derogation, of course, the turning device to be used, already the 'first' conductor insertion end 18 by an angle from the front of the head of the laying head for discharging 15 that the rotating piece 31 with its conductor outlet opening 17 is tilted, as it is equally possible to use a skew the second conductor insertion end 18 'to make. All this can be especially useful if the pads 11 and 11 'so ready that such an inclined - or horizontal - positioning of the conductor insertion end 18 or 18 'as particularly suitable question comes.
