Description

Method and device for manufacturing electrical harnesses

The present invention relates to a method and its implementation device for manufacturing electrical harnesses. The technical field of the invention is that of the manufacture of electrical harnesses.

Electrical harnesses are already used to equip many domestic or industrial electrical devices such as, for example, washing machines, automobiles, etc. Electrical harnesses consist of a plurality of conductive electrical wires which are grouped, for example, at the using plastic collar or adhesive tape, to form a set of electrical connections ready to connect and fix on a support. Each of the wires is previously cut to the desired length, then stripped, and its ends can be crimped onto a terminal or inserted on a component (connector, socket, etc.) as required.

The manufacture of the bundles then consists in grouping together the wires thus prepared and inserting their ends into components, and then in ensuring the cohesion of the bundle thus formed by connecting means such as collar or adhesive tape.

Methods and devices are already known for automatically manufacturing wires which are cut to the desired length, stripped and crimped, which are for example described in patent applications FR 88/16702 and FR 87/11392.

The general problem posed is to automatically make bundles of electric wires, which electric wires are supplied by known machines which generally comprise a linear conveyor on which transfer clamps move, each of these clamps holding one end of an electric wire. . Each of the electrical wires is thus held by two adjacent transfer clamps which follow one another on the conveyor.

There is generally downstream of this conveyor an insertion station where an insertion device can insert the ends of the wires into the receptacles for the components, starting with the first wire which appears at the outlet of the conveyor, then continuing with the following threads. The problem which arises here is to be able to insert ends of wires on components which have already received ends of other wires; in fact, the density of the receptor cells of the connectors means that in many cases. an automatic insertion device will not be able to insert the ends of the last wires to be inserted on this component, because it will be hampered by the presence of the wires whose ends are already inserted in this component.

Another problem is to be able to have in the immediate vicinity of the insertion station, previously prepared wires, when the bundles to be manufactured comprise very many wires and many components.

These problems are even more serious when the wires are numerous and the length of the beam is relatively short. According to the invention, the problem posed is answered by providing a method for manufacturing bundles of electric wires (1, 2. 3,

4) provided at their ends ^" with terminations which are intended to be inserted in receivers provided in components, each of said wires being held near its ends by two adjacent transfer clamps of a file conveyor, such that it involves the following operations: in a preparation phase:

- said components are placed on an insertion station,

a series of temporary storage pliers for the ends of said wires is provided near said insertion station and said file conveyor,

- we choose to insert these terminations in said receivers of said components, in a predetermined insertion order,

- said wires are ordered on said transfer clamps of said linear conveyor, so that the first wire (1), going up said line of said conveyor, includes the termination which must be inserted first according to said order of insertion into said receivers, and so that each of said next son (2), (3). (4). going up said line of said conveyor, comprises at least one termination which must be inserted, according to said order of insertion into said receivers, after at least one termination of each of said preceding wires, ie respectively after at least one termination of said wire (1), respectively after at least one termination of said wires (1), (2). and respectively after at least one termination of said wires (1), (2), (3). and in a storage-insertion phase, - the first wire located in said line of said conveyor is extracted by raising said line, from said transfer clamps, and at least one of said ends carrying said terminations of said first wire is inserted into one of said receivers, according to said insertion order, which end constitutes the last inserted end, and the non-inserted end of said first wire is placed in one of said storage clips, then successively for each non-inserted end:

- if the end which must be inserted after said last end inserted according to said order of insertion, is stored in one of said storage clips, one grasps and inserts into said receiver provided for this purpose said end which must be inserted , which end constitutes the last inserted end, or,

- if the end which must be inserted after said last end inserted according to said insertion order, is located on one of said wires held by said transfer clips, said wire is extracted from said transfer clips and at least one of said ends is inserted carrying said terminations of said wire in one of said receivers, according to said order of insertion, which end constitutes the last inserted end, and the non-inserted end of said wire is placed in one of said storage clips.

Advantageously, in the insertion storage phase, after having extracted said wire from said transfer clips and inserted at least one of said ends of said wire into said receiver, the non-inserted end of said wire is placed in said series of said temporary storage clips, according to an increasing order of the lengths of said wires while going up said series of said temporary storage clips.

Advantageously. said temporary storage clips of said ends are located on said linear conveyor, downstream of said transfer clips, between said transfer clips and said insertion station, and said temporary storage clips have a large storage capacity for said ends.

Advantageously, the ratio between said capacity of said temporary storage clips and the storage capacity of said transfer clips is greater than two and preferably greater than five, and preferably, said storage capacity of the ends of said temporary storage clips is at less equal to 50 ends per linear meter of said conveyor.

We also respond to the problem posed by providing a device for manufacturing bundles of electric wires provided at their ends with terminations which are intended to be inserted into receivers provided in components, each of said wires being held near its ends by two clamps. adjacent transfer of a linear conveyor, such that it has temporary storage clamps of said ends of said wires having a large storage capacity and such that said temporary storage clamps are located on said linear conveyor between said transfer clamps and a insertion station.

Advantageously, said temporary storage clamps comprise a base which can cooperate with said conveyor, so that the latter can drive said clamps, and said base is surmounted by a clamp body which has notches separated by walls, and said walls have at least one retaining projection which extends substantially along the opening of said notches. Advantageously, the device according to the invention comprises sections of flexible tubes which are liable to flatten and penetrate into said notches, the axis of said tube sections remaining substantially parallel to the longitudinal axis x * £ of said notches, so that when said tube sections are located in said notches, they can flatten, roll or deform, in order to allow the passage of said wires in said notches, and said tube sections can act as a stop which maintains said ends of said wire in said notch, and the ratio between the outside diameter of said tube and the width of said notches is between 1 and 2, and preferably between 1.1 and 1.4.

Advantageously, said flexible tube sections are hollow tube sections, and the ratio between the thickness E ^ of said tube flexible and its outside diameter is between 0.4 and 0.1.

Advantageously, said notches comprise at least one hollow groove arranged in one of said walls bordering said notch, and said groove extends substantially along said longitudinal axis xxj of said notch, and the free end of said walls is provided with inclined faces which facilitate guiding and introducing said flexible tube sections and / or said wires into said notches of said temporary storage clips, and at least one of said walls has at least one longitudinal stop which prevents said tube section from coming out of said cavity by a longitudinal displacement along said axis.

Advantageously, the device according to the invention comprises a manipulator device provided with means for gripping said ends of wires, which can introduce said wires into said notches, and said notches are superimposed at regular intervals along a substantially vertical axis, so that the it is possible to temporarily store in said temporary storage clamps more than fifty, preferably at least two hundred ends of said wires per meter of length of said conveyor. Advantageously, said manipulator device comprises at least one carriage which can move above said temporary storage clamps along an axis yy2 substantially parallel to the longitudinal axis of said conveyor, which manipulator device comprises means for placing said wire gripping means opposite the opening of one of said notches, so that said manipulator device can introduce and / or extract from said notches, said ends of said wires.

The methods according to the invention and their implementation device provide numerous advantages and in particular allow the manufacture of electrical harnesses having a high density of connections, and of ramifications.

The numerous advantages of the invention will be better understood through the following description which refers to the appended drawings which represent without any limiting character the devices according to the invention and steps of the methods according to the invention.

Figure 7 is a sectional view along VII-VII of Figure 6. We see in Figure 1A that we have on an insertion station 13 of four components 6] _, 62. 63. 64; said component 6χ has three receptor necks) 8 ^* ^ 0 • 8ll • ^ 12 into which must be inserted the ends of electrical wires; said component 62 comprises cells 820- 821-22- 823; the third component 63 comprises cells 830, 831, 832; the fourth component 64 comprises cells 840 and 8 1.

We see that in addition we have at the end of a conveyor

12 on which transfer tongs 9 can move in the direction of arrow S, electrical wires which are each held by two adjacent transfer tongs, each clamp holding one end of the wire. each wire being thus represented in the form of a pin.

The wires arranged on said transfer clamps have preferably been previously cut to the desired length, stripped and possibly crimped on lugs. In FIG. 1A, the arrow 01 represents the order of insertion which has been chosen to insert the ends 7 of said wires in said receivers of said components; indeed, provision has been made to insert said ends of said wires successively into the cells 8κ). 8. 8 ₁₂ . 8 ₂ o- 8 ₂ ι. 8 ₂ 2- 823. 8 ₃₀ . 8 ₃₁ . 832. 8 0 and 841- It can be seen that according to the invention, said wires 7 were made in an order such that the ends 7 of the wires held by said transfer clamps 9 on said conveyor 12 appear in an order where they are marked 7, 72. 3, 7 7 ^* ^ 2 • Indeed, we also know that the end of the first collector 6, that the end 7 of the second wire must be inserted in the cell 8-Q, that the end 75 must be inserted in the cell 812 • 1-- the end 72 must be inserted in the cell 820- the end 74 in the cell 821. the end lη in the cell 822 _* the end 79 in the cell 823. the end 7g in the cell 830. the end 7g in the cell 831, the end 7-Q in the cell 832. the end 7χ2 in the cell in 849. the end 7 * Q in the cell 8 1-

It can be seen in FIG. 1B that, in accordance with the invention, provision has been made for a series of temporary storage clips 11 of said ends of said wires.

It can be seen in the state shown in this figure that, in accordance with the invention, the first five wires have been extracted from said transfer clamps 9 from said conveyor 12. so that only the last wire remains in said transfer clamps having said ends read and 7 ^* [2-

It can be seen that at least one of said ends of said wires extracted from said transfer clamps has been inserted, more precisely said extremities 7χ, 73. 75, 72- 74, 7 ₇ have been inserted. 79 respectively in said cells 810 • 812- 812. 820- 821. 822.

823-

It can be seen that said non-inserted ends of said wires which have been grasped have been stored in said clips 11 for temporary storage; in the steps following the stage shown in this figure, we will. in accordance with the invention:

- grasp said end 7g stored in one of said temporary storage pliers and insert it into said cell 839. - grasp said end 7g stored in one of said temporary storage pliers, and insert it into said cell 8 1,

- extract said last wire from said transfer clips and insert said ends 7-Q and 7 * ^ 2 of said last wire respectively into said cells 832 and 840. - and finally, grasp said end IQ stored in one of said temporary storage clips and insert it into said cell 8 1- At this stage, the beam will be formed.

In FIGS. 2A to 2J, the main steps of a method of manufacturing beams according to the invention are shown.

It can be seen in FIG. 2A that there are wires marked 1, 2. 3, 4, each of these wires being held by two adjacent transfer clips 9 _] _, 92: it can be seen in this figure that said transfer clips are arranged on a file conveyor 12, which can advance said transfer clamps in a direction of movement represented by the arrow S. It can be seen that connectors are also available on an insertion station 13 located downstream of said conveyor 12 marked ^ l • 62- * 63 comprising cells (or receptors) 8. We see that in accordance with the invention, there are downstream of said transfer clamps, on said conveyor, temporary storage clamps 11, which are located near said insertion station 13. We see that said wire 1 has two ends 7j and 72. that said wire 2 has two ends labeled 73 and 74, that said wire 3 has two ends labeled 75 and ^' 7g, and that said wire has two ends labeled 7- and 7g. It can be seen that each of said wires is held close to each of said ends by said adjacent transfer clamps 9χ. 92-

In the example of implementation of the method according to the invention shown in FIGS. 2A to 2J, said wires are provided at their ends with connections which are schematically drawn by a thick line, or a cross, or a triangle, or a circle. It can be seen, in fact, that said ends 7 ^* [, 73, 75 are drawn using a thick line, that said ends 72-7g. 7η are drawn with said cross, that said end 74 is drawn with said triangle, and that said end 7g is drawn with said circle. Said thick line, said cross, said triangle and said circle indeed represent different types of connection which correspond to different types of cells in said connectors 6; it can be seen in FIG. 2B that said connector 6 comprises said cells 8 o “811 and -12 • 1-- said connector 62 comprises said cells 820” 821. 822 - 823. that said connector 63 comprises said cells 830 and 831: it can be seen in FIG. 2J which represents the bundle manufactured according to the method of the invention, that said connector 6 comprises cells which can receive said ends 7 of said thick line type son; it can be seen in this figure that said connector 62 comprises said cells 8 which are designed to receive cross-type connections; we see that the connector 63 includes said cells 8 which are designed to receive said triangle type connections; it can also be seen that one end of said wire 4 which is provided with said connection of the circle type is left free.

In the example shown in Figures 2A to 2J. it has been chosen to insert said ends of said wires into said components in the following order: 820. 8 - 822- 820. 82. 822. 83Q. Consequently, the order of insertion of said ends into said connectors is as follows: 72, 73, 75, 72. 7η, 7g, 7. the end 7g not being inserted in one of said connector.

It is seen in Figure 2B that in accordance with the invention, one begins by entering the first wire in said queue of said transfer clips, in the sense that one goes said queue of said transfer clips on ^'said conveyor, in the opposite direction to said direction of advance of said conveyor, in this case the wire marked 1; said end 72 of said wire 1 is placed in said cell 820 of said connector 62, and said second end 72 of said wire 1 is placed in one of said temporary storage clips 11, in this case said clip marked ll: we see in FIG. 2C that in the following operation, the second wire located in said line of said transfer clamps is grasped, going up said line in the direction opposite to said direction of advance, in this case the wire identified 2; it can be seen that in this phase, said end 73 of said wire 2 is inserted into said cell 8 of said connector 6. and said second end 74 of said wire 2 is placed in a temporary storage clip II3. It can be seen that said second end 74 of said wire 2 has been placed in said temporary storage clip II3. that is to say upstream with respect to said temporary storage clip 112. in which said end 72 of said wire 1 has been stored: in fact, said end 74 of said wire 2 must be inserted after said end 72 of said wire 1. according to said order of insertion. We see that in the next phase shown in Figure 2D. said third wire located in said line of said transfer clamps of said conveyor was gripped, while raising said line of said transfer clamps in the opposite direction to said direction of travel, in this case the wire marked 3. said end 75 of said wire 3 has been inserted into said cell 822 of said connector 62. and said end 7g of said wire 3 has been temporarily stored in said clamp II2. that is to say upstream of said end 72 of said wire 1 and downstream of said end 74 of said wire 2; in fact, according to said insertion order, said end 7g must be inserted after said end 72 and before said end 7. It can therefore be seen that said ends are placed in said storage clips, according to at least part of said insertion order.

It can be seen in FIG. 2E that in the next phase of the method according to the invention, said end 72 of said wire 1 is inserted into said cell 820 - second connector 62-

In figure 2F, it is seen that in the following phase, one grasps the fourth wire (item 4) located in said line of transfer grippers, and said available end 77 in said recess 82 of the connector 62 and range ^'said end 7g in said temporary storage clip II4. upstream of said temporary storage clips II3. H2. H 1-- contain respectively said ends 7 and 7g; in this way, going up said series of said temporary storage clamps in the opposite direction to the direction of advancement of said conveyor, we find said ends 7g. 74. 7g. that is to say that said ends are found according to at least part of said insertion order. In FIG. 2G, it can be seen that in the next phase, said end 7g of said wire 3 is inserted into said cell 822 of said connector 62: in FIG. 2H, said end 74 of said wire 2 is inserted into said cell 830 of said connector 63; in FIG. 21, it can be seen that said end 7g of said wire 4 is then grasped and which is removed from said temporary storage clip II4 in order to arrange it near said connectors; at the end of the operations represented in FIG. 21, said bundle was manufactured in accordance with the method according to the invention.

It can be seen in FIG. 2J, where said bundle has been represented at the end of the operations represented in FIG. 21. in another mode of representation, that said connector 6 receives said ends of wires 1, 3. 2 which are drawn by a thick line, that said connector 62 receives said ends 7 of said wires 1, 3, 4, which are represented by said crosses and that said connector 63 receives one end of said wire 2 represented by said triangle; and it can be seen that one end 7 of said wire 4 represented by a circle remains not inserted.

We see in Figure 3, which shows in side view an embodiment of a temporary storage clamp according to the invention, that said clamp 11 has a base 14 which can cooperate with said conveyor so that said conveyor can cause the displacement of said storage clamp 11. It can be seen that said clamp comprises above said base, a connector 15 which has notches 16 separated by walls 17. and said walls have a retaining projection 21 which extends substantially along the opening of said notches; it can be seen in FIG. 3 that sections of flexible tubes 18 which are liable to flatten and penetrate into said notches have been inserted into said notches, and that wires 19 have been inserted into said notches and are retained by said sections of flexible tubes.

In Figure 4, there is shown another embodiment of said temporary storage clips 11, wherein said notches 16 are superimposed at regular intervals along a substantially vertical axis zz; it can be seen that said body 15 of said temporary storage clamp which includes said notches, overcomes said base 14 of said temporary storage clamp, which base cooperates with said conveyor 12.

In Figure 4, there is shown schematically a manipulator device 24 which is provided with gripping means 25 of wire ends, which manipulator device can introduce said wires into said notches of said temporary storage clips. Said gripping means 25 comprise in particular a first jaw 29 and a second jaw 28 which can slide relative to said first jaw 29 in a direction substantially parallel to said axis zz \, for example under the action of a clamping cylinder 30; in this way, when said cylinder brings said ends closer to said jaws 28 and 29. a wire 19 can be clamped between said jaws so that it is held by said gripping means; it can be seen that, advantageously, said gripping means comprise a jack 31 for pivoting of said jaws 28 and 29 ; it can be seen that said jack 31 allows said jaws to pivot relative to an axis XX2-

Advantageously, said cylinder 31 and said axis XX2 are linked to a vertical carriage 32 which can slide substantially along said axis zz2 thanks to a vertical displacement cylinder 34 and a screw 35; said screw 35 makes it possible to position a nut 36 which serves as end of travel and limits the movement of said vertical carriage downwards due to the action of said vertical displacement cylinder; vertical guide means 33 can advantageously be provided to guide said movement of said vertical carriage, relative to a main carriage 26: it can be seen that a vertical stroke motor 37 makes it possible to drive said screw 35; we also see that under the action of said jack 31, which causes said jaws to pivot relative to said axis x 2- the end of said jaws which can hold said wire 19 will perform a movement in an arc of a circle represented by the arrow R. also sees that said main carriage 26 can move on a movement guide in translation 38 along an axis yy2 which. advantageously, is parallel to the axis of movement of said linear conveyor 12.

In FIG. 5, it can be seen that a beam manufacturing device according to the invention comprises said temporary storage clamps 11 which are located on said conveyor 12 downstream of said transfer clamps 9; it can be seen that, advantageously, the storage capacity for ends provided by said temporary storage clips which, in the example shown in FIG. 5, can each receive eight ends of said wires, is large compared with the storage capacity of said wires transfer clips 9 which can only receive one end of said wires; advantageously, said base 14 of said temporary storage clips is similar to the base 9A of said transfer clips 9. so that said temporary storage clips can be transported by said conveyor 9 initially provided for said transfer clips 9 without significant modification.

It can be seen that, in accordance with the invention, said temporary storage clips are located downstream of said transfer clips on said conveyor 12, that is to say between said line of said transfer clips 9 and an insertion station 13 in the direction of displacement

S of said conveyor 12. In Figure 5, there is shown a variant of a device according to the invention in which said gripping means comprise means 40 for removing at least one of said temporary storage pliers from said line of said temporary storage pliers and raising said clamp in a translational movement along a substantially vertical axis zz2, and comprises means 25 for gripping wires 19 which allows movement of said jaws 28. 29 according to an arc of circle R. Said means 40 may in particular comprise a motor 39 for vertical displacement which can cause the vertical displacement of a temporary storage clamp 11a by means of a screw 41. so as to position a notch 16a in which it is desired to insert said wire 19 at a height h corresponding to the height of one end of said jaws 28, 29.

In Figure 6, there is shown in partial section on a different scale a temporary storage clip according to the invention. We see that said clamp has a succession of notches 16 identified

16a. 16b, 16c. 16d, 16th and 16f. ^' We see that each of said notches is limited by walls 17 which separate two adjacent notches.

It can be seen that each of said walls has a retaining projection 21 which extends substantially along the opening 162 of said notches. We see that the first notch 16a, on the left in the figure

, is empty and that a flexible tube section 18a is available near said notch, which is intended to be introduced into said notch; we see that in the second notch 16b from the left in the figure, said flexible tube section 18b is being introduced into said notch; it can be seen that in the third notch 16c, starting from the left of the figure, said flexible tube section 18c has been introduced into said notch and is retained by said projection 21; we see that in the fourth notch 16d starting from the left, we begin to introduce the end of a wire

19d in said notch; we see that in the fifth notch 16th. a 19th wire is being introduced; and in the sixth notch

16f said wire 19f has been introduced into said notch. We see that in this embodiment, said flexible tube section 18a is hollow, of diameter Dl and has a wall of thickness El; advantageously. the diameter D1 of said flexible tube is greater than the width E2 of said notches; we see that said tube sections 18b, 18d, 18th, 18f, can deform to be introduced into said notches 16b. 16d, 16e, 16f due to the flexibility of said tube sections and the fact that said tube sections are hollow. We see that in said notch 16c, said flexible tube section 18c has been introduced and is substantially flattened because its diameter is greater than the width E2 of said notch. In said notch 16d it can be seen that, thanks to an insertion force F3, a wire 19d can be introduced by deforming said section of tube 18d. We see that in the 16th notch. said tube section 18e can roll and / or deform and / or slide to allow passage according to arrow F4 of said wire 19e. It can be seen that in the notch 16f, said wire 19f has been introduced and is wedged in a hollow groove I62 arranged in a wall of said notch, and said section of tube 18f prevents said wire 19f from coming out of said notch. We see that the free end 17a of said walls 17 which limit said notches are provided with inclined faces 22 and 23 which facilitate the introduction of said flexible tube sections and desditeε ends of wire.

It can be seen in FIG. 7 that said end of said wire 19f which extends substantially along said longitudinal axis X of said notch 16f is held in said hollow groove I62 of said wall 17 by said section of tube 18f; it can be seen that one of said wall 17 comprises two longitudinal stops I63 which prevents said tube section from leaving said cavity by a longitudinal movement along said axis -
