Definitions

  • the invention relates to an assembly head and a method for automated, in particular fully automatic, banding of a wiring harness.
  • a cable harness is generally understood to mean a strand-shaped, preferably flexible structure, in particular a preferably electrical cable bundle, which is composed of one or more (electrical) (line) elements (individual cables).
  • line electrical
  • the individual elements are often combined using banding.
  • a band for example an adhesive tape and/or a textile band, is wrapped around the wiring harness.
  • the invention is based on the object of enabling automated banding.
  • the object is achieved according to the invention by a mounting head according to claim 1 and by a method using such a mounting head according to claim 24.
  • the assembly head is generally used for automated, in particular fully automatic, banding of a cable harness extending in a transverse direction with a band.
  • the mounting head itself also extends in a longitudinal direction and in a vertical direction. It has a winding module with a winding head that can be rotated about a rotation axis extending in the transverse direction.
  • the winding module preferably has a drive via which the winding head can be set in a rotational movement.
  • the winding head itself preferably has a ring segment with a central winding space.
  • the ring segment has a lateral insertion opening for the lateral (transverse to the transverse direction) insertion of the cable harness into the winding space.
  • the drive is designed in particular in the manner of a belt drive, with a drive belt engaging in particular in an external toothing of the winding head and thereby causing it to rotate.
  • the assembly head also has a banding unit for providing and guiding the band.
  • the wiring harness and the mounting head are moved relative to one another in or against the longitudinal direction, so that the wiring harness is inserted laterally into the winding head.
  • the tape is then applied to the wiring harness and then the tape is wrapped around the wiring harness.
  • the conduction band is finally separated and cut off. A movement preferably follows to securely adhere the end of the band to the cable harness.
  • a suitably designed control unit is generally arranged to control the movement sequence of the assembly head, with the help of which the individual steps and movements during banding, as will be explained in detail below, are initiated.
  • the cable harness usually consists of several individual cables. These are preferably single-core or multi-core electrical sheathed cables. Alternatively, the line elements are also busbars that are wrapped with the tape. In principle, other types of individual cables or different types of individual cables can also be combined in the cable harness. In one embodiment variant, at least some of the individual lines are designed as fluid lines, such as hoses.
  • the wiring harness is preferably a purely electrical wiring harness.
  • a first preferred aspect can be seen in the design and control of a cutting element, especially in combination with a (further) pressing element according to claims 2-10.
  • This configuration means that at the end of the banding process a fully automatic separation of the band and preferably further pressing of the band end onto the cable harness is achieved.
  • the cutting element is in particular attached to the banding unit and is therefore part of the banding unit.
  • the cutting element is designed in the manner of a blade which is oriented in particular in the transverse direction.
  • the banding unit is generally attached to the winding head, regardless of the arrangement of the cutting elements on the banding unit.
  • the winding head rotates around the axis of rotation and therefore the banding unit attached to the winding head also rotates.
  • the cutting element In the embodiment in which the cutting element is attached to the banding unit and so that it is part of it, the cutting element also rotates during the banding process.
  • the banding unit is preferably controlled in such a way that it is moved into a cutting position, in particular counter to the longitudinal direction, at the end of the banding process. This movement brings the cutting element into a defined cutting position. By retracting the banding unit, it is moved away from the wiring harness. In particular, the band is tensioned so that it can be separated more easily.
  • the banding unit is therefore generally movable and adjustable, in particular on or with the winding head.
  • An actuating mechanism with an actuator is therefore designed, via which the desired actuating movement of the banding unit can be carried out.
  • the banding unit has a band dispenser to which the band, specifically a band roll, is attached.
  • the band supply is generally dimensioned such that it is sufficient for several bandings. If the tape supply on the tape roll is used up, a new tape roll is fixed on the tape dispenser. Alternatively, the tape is wound directly on the tape dispenser.
  • the cutting element can be moved in the direction of the band to cut through the band.
  • the cutting element is, for example, movably arranged on the banding unit.
  • the cutting element is preferably moved by moving the banding unit, and in particular also the winding head to which the banding unit is attached, in particular without relative movement to the banding unit.
  • the cutting element is moved in the direction of the belt by a pivoting movement. This in turn is done in particular by a pivoting and thus rotary movement of the banding unit and thus in particular also of the winding head.
  • the particular advantage here is that there is a rotary drive for the rotary movement of the winding head at the same time is also used to cut the tape with the cutting element.
  • a tape end is formed on the separated partial tape, which is wrapped around the wiring harness.
  • a pressing element is provided, which can be moved in the direction of the wiring harness, such that the end of the tape is pressed against the wiring harness during operation during the banding process.
  • the press-in element is also referred to below as a further or second press-on element.
  • This further pressing element is preferably also attached to the banding unit.
  • the further pressing element is preferably moved by a rotary movement. In a preferred embodiment, this is again done by the rotational movement of the banding unit and in particular of the winding head.
  • both the cutting element and the further pressing element are attached to the banding unit. Since this in turn is connected in a rotationally fixed manner to the rotatable winding head/banding unit, at the end of the banding process the band is cut and the end of the band is pressed onto the cable harness by at least one suitable pivoting movement of the winding head.
  • a common pivoting movement is sufficient for cutting the band and for pressing the end of the band against the cable harness, so that first the cutting element cuts the band and then the further pressing element presses the band end against the cable harness.
  • the cutting element and the further pressing elements are therefore arranged one behind the other in a preferred embodiment against a pivoting direction. They are therefore arranged rotationally offset from one another.
  • the further pressing element is designed in a preferred embodiment as a flexible tab or a brush.
  • the other, second band end which still remains on the band supply provided by the band dispenser and thus represents a beginning of the band for the next banding process, also forms a band end.
  • a holding element is arranged for the second band end, which acts in particular as a supporting and/or fixing element for the band end.
  • the holding element is arranged adjacent, and preferably directly adjacent, to the cutting element.
  • the holding element holds the second band end in a defined position, for example, supports and/or fixes it, so that it can be moved back to the cable harness in a controlled manner during a subsequent banding process and attached there.
  • the problem when cutting off the tape is that the second tape end protrudes into an undefined position, from which reliable attachment for the following banding process cannot be reliably guaranteed.
  • the holding element is further preferably formed by a plurality of individual pins, in particular needle-shaped pins, which preferably extend from a base upwards in the direction of a central winding space and thus to the band.
  • these pins pierce the band so that it is perforated by the pins, and the band is fixed in the desired position at the points where the pins pass through.
  • the banding unit preferably has a band dispenser on which the band is stored.
  • the banding unit together with the band dispenser is attached to the winding head and therefore rotates with it during the banding process.
  • a balancing mass is attached to the winding head and in particular to the banding unit.
  • This is an additional mass element that otherwise has no additional function.
  • the mass element is formed in particular by a solid, for example cylindrical or cuboid body made of solid material.
  • the additional balancing mass achieves a suitable mass distribution in such a way that imbalance is avoided when the winding head rotates.
  • the mounting head generally has a support frame to which the individual elements of the mounting head are attached.
  • the winding module can be moved in the longitudinal direction relative to the support frame, in particular together with the banding unit.
  • suitable drive and adjustment elements are provided in particular, for example a suitable linear guide with a drive.
  • the winding head and with it the banding unit are moved in the longitudinal direction relative to the support frame and are thus advanced in the direction of the conductor band and moved back again. This allows an efficient banding process to be implemented because the entire assembly head does not have to be moved. This also serves to avoid collisions with other components that are intended to hold the wiring harness.
  • the cable harness is generally routed onto a holding device, for example a so-called cable board, i.e. it is laid and held in accordance with a predetermined laying geometry, for example with suitable support elements.
  • the banding is then carried out on this holding device using the assembly head.
  • a fully automatic fixing of the beginning of the band on the wiring harness is generally possible with the help of the banding unit. There is therefore no need to manually attach the beginning of the band.
  • the subsequent banding is also fully automatic.
  • the fully automatic fixing takes place in particular by moving the banding unit forward the wiring harness. For this purpose, in particular, the previously described relative movement of the winding module relative to the support frame is provided.
  • the banding unit has a (first) pressing element which can be moved in the direction of the cable harness.
  • the pressing element is, for example, movable on the banding unit and is specifically held in a pivotable manner. Alternatively, it is fixed in place on the banding unit and the approach to the line band is carried out by a feed movement of the banding unit, which in particular also includes a pivoting movement.
  • the first pressing element is designed, for example, in the manner of a strip-shaped element or alternatively in the manner of a pressure roller, which is moved against the cable harness and thereby presses the beginning of the band against the cable harness.
  • a further preferred aspect can be seen in the design and control of a gripping unit, which has gripping elements that serve to compress the cable harness consisting of the plurality of individual lines or individual strands.
  • two gripping units are arranged on both sides of the winding head.
  • only one gripping unit is arranged on one side, so that the mounting head is designed to be as compact as possible.
  • the gripping unit is arranged in particular on the side opposite the banding unit next to the winding module.
  • the gripping unit of the banding unit is preferably arranged “leading” so that the loose individual lines in the section to be banded next are compressed by the gripping unit.
  • the gripping elements In a closed end position, the gripping elements completely enclose the cable harness in the circumferential direction, at least in connection with a further gripper holder, on which they are preferably mounted in a pivotable manner.
  • the individual, in particular loose, lines of the cable harness are first pressed against each other in the end position and press them together in a first, compressed end position.
  • the individual lines are preferably subsequently replaced by a further auxiliary element, kept compressed, in particular by the guide rollers described in more detail below, during the banding process.
  • the gripping unit is preferably transferred to a further, second end position or gripping position, in which the gripping elements release the cable harness again somewhat, in such a way that the cable harness is preferably only held loosely in this gripping position.
  • This means that the cable harness can be guided through the gripping unit in the transverse direction or that the assembly head can be moved along the preferably fixed cable harness during the banding process.
  • the gripping elements are curved.
  • the desired compression of the individual lines of the cable harness takes place by means of a pivoting movement.
  • the cable harness is pressed together in particular between these two arcuate gripping elements and the previously mentioned gripping holder.
  • a suitable drive is designed to carry out the pivoting movement.
  • An actuating element is specifically designed which acts on a foot area of the gripping element and pivots it about a pivot axis.
  • the gripping unit is also arranged to be linearly movable in and against the longitudinal direction, preferably relative to the winding module.
  • the gripping unit is in particular attached directly next to the winding module. Specifically, it is attached to the winding module, for example via linear guides, so that it can be adjusted in the longitudinal direction relative to the winding module.
  • a suitable drive is arranged for the adjustment movement.
  • the wiring harness is generally held at least on one side, preferably on two opposite sides, between which the assembly head is located, and in particular is kept tensioned.
  • the assembly head is moved in the transverse direction, in particular along the cable harness.
  • guide rollers which are preferably arranged in pairs on both sides of the winding head.
  • the guide rollers of a respective pair can be adjusted in the direction of the cable harness, in particular can be moved in the longitudinal direction and can also be pivoted in such a way that they are pressed against the cable harness during operation and in particular also press it at least somewhat together and, for example, deform it.
  • the cable harness has a flat cross-sectional geometry in the area of the guide rollers. Overall, this prevents the wiring harness from twisting around its own axis (twisting). During the banding process, the cable harness is therefore held between the two guide rollers of a respective pair.
  • the guide rollers are preferably without their own drive and are loosely mounted so that they can be rotated about a roller axis.
  • the assembly head preferably moves in the transverse direction along the cable harness. This is made possible by the guide rollers in that they roll on the cable harness so that it can run through the two guide rollers.
  • the respective pair of guide rollers can preferably be adjusted in the longitudinal direction.
  • at least one of the pairs is attached to the gripping unit and can be advanced together with it in the longitudinal direction.
  • the at least one pair of guide rollers is preferably arranged within a free space of the winding module.
  • the pair can preferably be moved into the free space, specifically in the transverse direction.
  • this pair is arranged within the free space.
  • this pair can preferably be moved in the transverse direction relative to the winding module.
  • the gripping unit can be moved overall in the transverse direction relative to the winding module.

  • the winding head 18 and with it the banding unit 20 rotates around the axis of rotation, so that the band 14 is unrolled from the band dispenser 22 and wound around the cable harness 10.
  • the tape 14 is preferably first wound several times around the wiring harness 10 at the starting position, so that the beginning of the tape is reliably fixed.
  • the cable harness 10 is wrapped in a spiral shape with the tape 14.
  • the gripping unit 26 preferably holds the wiring harness 10 firmly enclosed until the start of this spiral wrap. In general, before the start of the spiral wrapping, the gripping elements 30 are opened again slightly, so that the cable harness 10 is still completely encompassed, but is only held loosely.
  • the entire assembly head 2 is moved specifically with the help of the industrial robot 8 in or against the transverse direction Q, so that the tape 14 is successively wrapped around the cable harness 10 either as a spiral banding or as a full banding.
  • the assembly head 2 also enables spot banding, in which the tape 14 is only wrapped around the cable harness 10 in one position.
  • the band is automatically cut off.
  • the banding unit 20 (together with the winding head 18) initially moves back a little in the opposite direction to the longitudinal direction L.
  • a section of the band protrudes from the cable harness 10 in the radial direction.
  • the band 14 is tightened and is therefore taut.
  • the band 14 is severed using the cutting element 23.
  • a pivoting movement of the banding unit 20 is provided, for example around the axis of rotation of the winding module 16.
  • the cutting element 23 is guided from below against the tensioned band 14.
  • the cutting element 23 cuts the band 14.
  • the banding unit 20 (together with the winding head 18) initially moves back a little in the opposite direction to the longitudinal direction L, so that the band 14 is tensioned. The banding unit 20 then moves forward a little in the longitudinal direction again, so that the band 14 is relaxed and is no longer elastically tensioned, but there is sufficient space for the cutting element 23 to cut. This prevents the band 14 from rolling back/pulling back due to the elasticity after cutting and no loose beginning of the band would be available for the subsequent banding process.
  • the loose end of the band generated in the process is preferably also pressed against the cable harness 10 by the further pressing element 25.
  • an end band end remains on the band 14 located on the band dispenser 22, which defines the beginning of the band for the next banding process.
  • This band end is held in a defined manner by the arrangement of the holding element 27.
  • the holding element 27 - as can be seen in particular in FIG. 3 - is formed by several pins, in particular needle-shaped ones, which even pierce the band.
  • the piercing occurs in particular when cutting when the cutting element 23 is pivoted from below against the band 14.
  • the holding element 27 is preferably pivoted with the cutting element 23.
  • the needle-shaped pins pierce the end of the band. This means that the pins hold the band end firmly in position for the next bandaging.
  • the pins only protrude slightly beyond band 14 (shown exaggerated in the figures).
  • the fire end is held in position by the pins.
  • the first pressing element 24 guides the band 14 to the cable harness 10 by pivoting movement, so that the band 14 is pressed against the cable harness 10 and can adhere there.
  • the end of the band is then automatically released from the pins.
  • the band 14 is generally held in position by the first pressing element 24.
  • the pins hold the end of the band downwards after cutting, in particular, until the next banding process.
  • the holding element 27 is arranged directly adjacent to the cutting element 23. This is understood in particular to mean that the holding element 27 and thus the support location for the band end is at most a few centimeters, for example a maximum of 2 cm or a maximum of 1 cm, away from the cutting element 23.
  • either another cable harness 10 is brought into a desired banding position in which it is held and/or the assembly head 2 is moved to a next cable harness 10.
  • FIG. 5 An alternative variant of the mounting head 2 is shown in Figures 5 and 6.
  • the holding element 27 is omitted.
  • a respective pair of guide rollers 32 is preferably each attached to a respective gripping unit 26.
