    Description

    BRIEF DESCRIPTION OF THE DRAWING

    [0030] The FIGURE of the drawing is a diagrammatic, perspective view of a conductor being laid on a main body of a cell contacting system according to the invention.

    DETAILED DESCRIPTION OF THE INVENTION

    [0031] Referring now to the FIGURE of the drawings in detail, there is shown the production of a cell contacting system 2, of which the FIGURE shows an extract merely symbolically and which has a main body 4. A start node 6 is stationarily arranged and eight guide elements 8a-h, in this case pins or laying pins, are temporarily or fixedly arranged on the main body 4.

    [0032] Two low-voltage paths 10a,b of the cell contacting system 2 are to be produced on the main body 4. A guide head 12 in the form of a laying head with a wire guide nozzle is provided for this purpose. The head can be moved in all three spatial directions x, y and z. The guide head 12 or the wire guide nozzle has a discharge opening 14 for discharging an electrical conductor 16 in the direction of the arrow 18.

    [0033] In order to create the low-voltage paths 10a,b, the guide head 12 is guided by machine in the direction of arrow 22 along a path 20, which is predefined by program technology and is only indicated here, by a robot arm that is not illustrated. As a result of this, the guide head 12 moves relative to the main body 4. The conductor 16 is discharged from the guide head 12 in the direction of the arrow 18 and laid on the main body 4 to form the low-voltage paths 10a,b.

    [0034] In the example the entire conductor 16 including an intermediate piece 24, illustrated using dashed lines, is laid.

    [0035] Overall, therefore, the conductor 16, in this case a wire, is fixed to the starting point 26 of the first low-voltage path 10a by way of an auxiliary device, the guide head 12 or laying head or—as in this case—by way of a geometry suitable for connection, in this case the start node 6 in the form of a welding fork. The conductor 16 is then guided by the tool suitable for this purpose, in this case the guide head 12 or the wire guide nozzle. The path 20 can be determined freely in all degrees of freedom. The movement of the guide head 12 and the discharging of the conductor 16 from the guide head 12 or the discharge opening 14 are carried out automatically by means of a programmable control program. During the laying process, the wire tension is kept at an approximately constant value by way of a wire tension brake that is arranged upstream of the guide head 12 counter to the direction of the arrow 18 and is not illustrated. The tension is held in relation to the conductor section 7 that is already fixed to the start node 6. The start node 6 is therefore a winding fork in this case.

    [0036] The guide elements 8a-c serve to guide or fix the low-voltage path 10a along a desired course. At the end 28 of the low-voltage path 10a, the conductor 16 is in turn fixed by a suitable connection, in this case a fixing winding around the guide element 8d. The latter thus forms an end node 30 for the low-voltage path 10a. In the case of a “point-to-point” operation, the conductor 16 would be cut at this point and the first low-voltage path 10a would be created. The guide element 8d (like the guide element 8e, see below) can therefore also be a guide element and/or contacting element in an alternative embodiment.

    [0037] In the present example, however, there is an endless laying process; the conductor 16 is therefore guided further to the guide element 8e without interruption and without losing the wire tension, and—again by way of a fixing winding on the guide element 8e—is fixed there. The guide element 8e forms the starting point 26 of the second low-voltage path 10b. The low-voltage path 10b is then along the guide elements 8f-h, etc.; in the FIGURE the creation of the low-voltage path 10b has not yet concluded, further guide elements and another end node are not illustrated.

    [0038] In order to ensure the electrical connection in the case of the endless laying process shown in the example, i.e. to ultimately create the two low-voltage paths 10a,b, the endless wire in the form of the conductor 16 is separated at the corresponding places, i.e. between the two low-voltage paths 10a,b, and the remaining parts of the wire—i.e. the intermediate piece 24, which is illustrated using dashed lines and is no longer necessary, of the conductor 16—are then removed.

    [0039] Additionally, at the start node 6 and at the guide elements 8d,e, the conductor 16 makes electrical contact with the relevant component as counterpart 34. The guide head 12 thus simultaneously forms a contacting head 32.

    [0040] In a manner not illustrated in the FIGURE, at the end of the low-voltage path 10b the conductor 16 is welded to, and as a result makes electrical contact with, a counterpart 34, namely a contact plate, by way of an alternative contacting head 32, namely a welding head.
