Definitions

  • the present invention relates to a process for recognising electric wires forming a first cable in order to weld, connect, grip said wires to corresponding wires forming a second cable, or to printed circuits, connectors, terminals etc.
  • the invention further relates to systems and/or apparatuses used for carry out the process.
  • a cable is an electric line consisting of more wires covered by insulating material in the entire development, and housed inside protecting coating.
  • In the denomination of electric cable are comprised all types of cables, wires, cords, conductors and leads used in the electric systems and equipments of telecommunication.
  • a cable comprises a sheath or circular protecting or continuous coating applied on the wires; these consist of a metal conductor coated by an insulator suitable for standing to the voltage; the insulator is also used for obtaining the cores; therefore, a core is a wire coated by an insulator, when it is a part of a cable.
  • the main purpose of the present invention is to obviate these disadvantages.
  • the invention, as claimed, solves the problem of defining a process for recognising and/or connecting electric wires of a cable.
  • a second purpose of the present invention is to create systems and/or apparatuses for carry out the process.
  • Each phase is carried out according to particular protocols which can be replied for each working cycle in order to obtain end-items with controlled quality.
  • the phase A is carried out by means of a separating device capable of separating the electric wires belonging to a first cable to begin the subsequent recognising phase B; in fact, before the phase A the sheaths of the electric wires, which are at an end of said cable, are removed and separated to each other so that it is possible to separately recognise each wire of the cable.
  • the phase B is carried out by maintaining the separating device in the position of separation of the electric wires and by examining at least one physical feature of each wire of the cable by means of a device suitable for the exam; during the phase B, the wire having the required physical feature is disposed in a sequence suitable for the welding, connection or gripping, forming the subsequent phase C, the last of the working cycle.
  • the examined physical feature is the colour of the insulating coating of each wire; an other physical feature characterising each wire is the inductance which can be quantified by means of a tester during the phase B.
  • the apparatuses for carrying out the process according to the present invention comprise:
  • a device for the connection of the cables capable of displacing the end of each wire, until it is moved into the position suitable for the welding, connection or gripping.
  • the device shown in Figures 1 to 3 is used for separating the wires without the sheath of a cable.
  • This device essentially consists of a self-centring vice 1 supporting an end of a cable 2; from the end a plurality of wires 3a, 3b protrudes, the wires 3a, 3b being coated by coloured insulating material; the vice 1 consists of three wheels 4, 5, 6 adhering to the external surface of the end of the cable 2 for loading it with a torsional stress.
  • the wheels 4, 5, 6 are rotated by a motor 7 feed by a source of electric energy 8 and controlled by a central control unit 9; a plurality of emitters 10 is provided each emitting a beam of polychrome light towards a respective wire 3a, 3b; the mirrored light presenting the colour of the coating of the wire 3a, 3b comes back towards the sender 10 (used as receiver) connected to the central control unit 9 through an amplifier 11 of the signal of the sender - receiver 10.
  • Each sender 10 is sensitive only to a colour so that it changes the level its signal when receives the mirrored light of said colour; therefore, each sender 10 sends to the central control unit 9, through the amplifier 11, an electric signal the first level of which shows that the mirrored light has the colour to which the sender 10 is sensitive, while the second level shows that the mirrored light has not the colour to which the sender 10 is sensitive, respectively.
  • a wedge-shaped push rod 12 is near the end of the cable 2; the push rod 12 is supported, for example, by a sliding guide (not shown) to move from the position of Fig.1 to the position of Fig.3 et vice versa.
  • the second level of the signal of the sender 10 enables the central control unit 9 to set at work the motor 7 until the wires 3a, 3b are disposed in the sequence suitable for welding, connection or gripping, considering the reference sequence A, B, C, D of the wires of the cable 2.
  • the device shown in Figures 4, 5 is identical to that of previous Figures except for the fact that the recognising sensor consists of a sensor 14 of a electrical characteristic of the wires (impudence, tension, current, frequency and the like).
  • the wires 3a, 3b are not separated; vice versa, when the configuration of Fig.5 is reached the wires 3a, 3b coming out from the cable 2 are separated by the push rod 12 to allow that each sensor 14 to contact the metal of a wire; if the sensor 14 in contact with the wire 3a measures that the value of the examined electrical characteristic is suitable for the cable, the connection to the printed circuit, the connector, the terminal and the like, to which the wire 3a has to be connected, the central control unit 9 receives from the sensor 14 a signal the first level of which enables it to maintain the motor 7 still so that the wire 3a is maintained in the original sequence.
  • the central control unit 9 receives from the sensor 14 the signal at the second level enabling it to set at work the motor 7 until the wires 3a, 3b (and the other not shown) are moved into the sequence suitable for the welding, connection or gripping, considering the reference sequence A, B, C, D of the cable 2.
  • Fig.6 represents schematically a perspective of a welding device comprising a supporting structure 15 for two actuators 16, 17 manoeuvred by a central control unit (not shown).
  • the actuators 16, 17 are specular; therefore, the description of the components and functions of the first actuator 16, is also sufficient for the components and functions of the second actuator 17.
  • the actuator 16 (17) consists of a bracket 18 (19) rotating around a pin 20 (21) supported by the structure 15 (or by the structure, not shown, specular to the structure 15); a cursor 22 (23) slides in the horizontal part of the bracket 18 (19) supporting the cursor 22 (23) and grips a wire 3a (3b).
  • Devices are provided controlled by the central control unit to rotate the bracket 18 (19) around the pin 20 (21) and to slide the cursor 22 (23) in the horizontal part of the bracket 18 (19); these devices are known, therefore they are not shown.
  • Figs 7, 8 represent schematically a third embodiment of the separating device before having squashed an end of a cable 2; the wires A, C, B, D come out from the cable 2 being placed in a erroneous sequence.
  • a vice 25 consists of a fixed structure 26; the wires A, C, B, D of the cable 2 and a movable structure 28 rest on a lower jaw 27 of the fixed structure 26, the jaw 27 sliding on a supporting structure 29 so that the upper jaw 30 can squash the wires A, C, B, D resting on the lower jaw 27 to separate them in a common plane.
  • Figs 9, 10 show the separating device of Figs 7, 8 squashing the end of the cable 2 with both jaws 27, 30 of the vice 25 in contact.
  • each wire 3a, 3b, 3c, 3d is firmly supported by a pincer 32, each pincer presenting an elongated body 33, a supporting basis 34 and a clamping zone 35 for a wire A, B, C, D.
  • the supporting basis 34 of each pincer is housed in a panel 36 presenting four parallel guides 37, 38, 39, 40 and two guides 41, 42 perpendicular to the previous. All guides are coplanar allowing the displacement of the supporting basis 34 of the pincers 32.
  • the numbers concerning the pincers 32 were replaced with the letters of the relevant wires located in erroneous sequence A, C, B, D to better understand the functioning of the panel 36 in Figs 14, 15, 16.
  • the central control unit 31 If the receiver 10 of each wire connected to the central control unit 31 recognises that the colours of the coatings of the wires A, B, C, D (or other physical characteristics, as specified above) are not in the right sequence, the central control unit 31 enables four actuators (not shown) to move the basis 34 of the relevant pincers 32 until the wires A, C, B, D are disposed in the sequence A, B, C, D, suitable for the welding, connection or gripping.
  • the central control unit 31 recognises, in every instant, the positions of the basis 34 relevant to the wires A, C, B, D to avoid impacts during the movement towards the right sequence.
  • the basis 34 in panel 36 are disposed in erroneous sequence A, C, B, D; that is demonstrated by the fact that said sequence is shown in the lower part of the panel 36 illustrating the initial situation.
  • the central control unit 31 recognises the erroneous position of the wire C and, considering this information, enables the actuator of the base relevant to the wire C to move it in the guide 38 until the guide 41 is reached.
  • the central control unit 31 stops the actuator of the base relevant to the wire C in the guide 41, since said unit is informed that the guides 37, 39, 40 are engaged by other basis, and cannot be covered. Therefore, the central control unit 31, by recognising the erroneous position of the wire B, enables the actuator of the base of the wire B to move said base in the guide 39 to reach the guide 42, but not the guide 41 since the unit is informed that the last is engaged by the base of the wire C.
  • the basis of the wires B, C are found in the positions of Fig.14 and replayed in the subsequent Fig.15.
  • the subsequent movements imposed by the central control unit 31 comply with said logic consisting in acting so that the basis of the pincers of the wires displace only in the free guides until the sequence A, B, C, D, suitable for the welding, connection or gripping (Fig.16), is reached.
  • the wedge-shaped push rod 12 shown in Figs 17 to 21 presents four longitudinal grooves 44, 45, 46, 47 each capable of housing the end of a relevant wire to maintain the adherence of the wires to the push rod 12 after the recognising phase; in addition, a vice 48 is provided gripping the wires on the longitudinal groves 44, 45, 46, 47 to increase the adherence and opportunely form the wires.
  • the vice 48 (Figs 18 to 23) comprises two jaws 49, 50 which wind the body of the wedge-shaped push rod 12 and grip the wires on the longitudinal groves 44, 45, 46, 47 and two levers 51, 52, respectively, integral with the jaws 49, 50 and articulated around a pin 53. Both jaws 49, 50 are shaped to adhere to the external surface of the wedge-shaped push rod 12 when both levers 51, 52 are gripped by opposite stresses F1, F2; when both levers 51, 52 are separated the wedge-shaped push rod 12 is free.
  • the vice 48 is gripped on the push rod 12 before the recognising phase and open again after the same phase.
  • Figs 22, 23 show both jaws set free by the wedge-shaped push rod 12.
  • Figs 24, 25 show a fourth embodiment of the separating device being very similar to that of Figs 7 to 11.
  • a fixed structure 54 supports a lower jaw 55, on which the end of the cable 2 leans.
  • a movable structure 56 slides with respect to the fixed structure 54 in directions E1, E2 and supports a upper jaw 57.
  • the jaws 55, 57 present inclined planes allowing to squash the wires of the cable 2 to separate them in a common plane.
