Definitions

  • the present invention relates to an automatic wiring station adapted for incorporation to machines used to prepare electrical wire leads cut to size and fit them with electrical terminals which may be provided with some insulating protections.
  • That machine which is computer controlled, enables electrical wire leads to be cut to size, whilst removing an insulator segment from both ends thereof, and fitted with electrical terminals for connection purposes, which terminals may be enclosed, if necessary, within an insulating protection.
  • the machine produces wire lead segments or sections which are ready for wiring bases or boards equipped with complementary connectors t the connectors associated with the bases or boards being of the "male” type,whereas the connectors fitted to the lead ends are of the "female” type.
  • Wiring is a time-consuming and expensive manual operation, in the course of which an operator must pay great attention not to erroneously exchange and incorrectly apply the connectors to the multiple base.
  • Another object of the invention is to provide a station for incorporation to a machine which prepares the electrical cable segments and fits them with electrical connectors, so as to complete automation of the operations for preparing prefabricated elements for mass production electrical systems.
  • a further object is to provide a machine which is programmable, thereby it can select in each case, a lead of suitable cross-sectional area according to whether the line is a power one or a duty or signal line.
  • Still another object is to provide a machine equipped with grip means adaptable to a variety of bases to be wired, said means being operative to position the base for a multiple or otherwise complex wiring operation.
  • a not unimportant object is to provide a wiring station comprising simple, strong members, adapted to allow fast and accurate working sequences.
  • an automatic wiring station particularly for machines for preparing cut-to-size electrical wire leads fitted with insulatable electrical terminals, characterized in that it comprises:
  • the wiring station of this invention is particularly adapted for co-operation with a machine for stripping insulating sheath from an end of a piece of wire and clinching a terminal thereto which comprises two clinching stations formed of two presses 1 and 2, respectively, as shown in Figure 1.
  • This machine is programmed to cut an electrical wire lead to size and strip its end of the insulator over an appropriate length, that stripped area is then fitted with an electrical terminal by the intervention of two presses indicated in Figure 1 by the reference numerals 1 and 2.
  • the invention relates to a farther station, particularly for co-operation with that machine, which effects the automatic and programmed wiring of a multiple connector base indicated at 4 in Figure 1 and belonging, for example, to a timer 5 for a domestic appliance.
  • a rotatable base 6 which may be rotated by conventional actuation means such as motor or an appropriately mounted hydraulic piston, the base 6 carries a turret generally indicated at 7 which has a supporting plate 8 extending substantially in a vertical plane and supporting all of the turret members.
  • these members comprise a shoulder 18 associated with the supporting plate 8 and including a seat 18a adapted for accommodating a portion of the circumference of a wire to be gripped thereon by a gripper 9, including a mouth 9a, shaped to substantially envelop the shoulder 18 to grip a wire therebetween.
  • the gripper 9, is journalled by a pin 10 to a bracket 10a rigidly associated with the supporting plate 8 and defining a double lug or yoke 11, penetrated by a second pin 12 which fits slideably into a seat 13 on an enlarged head 14 rigid with the free end or piston rod 15 of a small pneumatic control cylinder 16, mounted on the supporting plate 8.
  • the station mounted on the turret 7 is also provided with a deflector 19 which, when in its closed position, guides the head of the wire fitted with the terminal 20 into the gripper 9, which would be open, and when the latter is closed, pivots on a hinge 21 under control by a second small double-acting pneumatic cylinder 22 to let the wire 3 run therethrough without interfering.
  • the deflector 19 has a curved advancement face, indicated at 24 and lying rectlinearly in the zone 19 wherealong the wire can be easily advanced and deviated or deflected in its course towards the means present on the turret 7. upon the wire being advanced, the tqrret 7 occupies the position indicated at A in dash lines.
  • That end of the wire 23 which is provided with the terminal 20 projects by a suitable length from the gripper 9 and is inserted into a guide channel 25 journalled in the proximity of the gripper 9 and being held at an aligned position by a spring, not shown.
  • the guide channel 25 serves the purpose of orienting the electrical terminal 20 in a correct position.
  • the electrical connector is now positioned at the area of the insertion pusher, generally indicated at 28.
  • Said insertion pusher assembly 28 comprises a vertical plate 29 made fast with the machine frame 100 which supports two side frames 30 and 31 between which are two cylindrical guides 32 and 33 which function as supports for a slide 34 which carries a vertical rod 35 formed, at its bottom portion, with a yoke 36 which is adapted to grip the lead 26 at the clinching area of the terminal 20.
  • a further air-operated piston 38 translates the slide 34 horizontally between two end positions between the two side frames 30 and 31.
  • a conventional adjustable travel end stop 39 enables the full forward position of the slide 34 to be adjusted.
  • the terminal 20 With the turret at the position B, the terminal 20 is located within a guide channel 40 formed by a bearing base 41 and a cover 42 journalled at 43 to be opened and closed by the yoke 36 whose shank 44 is passed through a slot 45 formed in the cover 42.
  • the slot 45 extends over a length equal to the full stroke excursion of the slide 34 so as to allow the cable 26 to be held firmly while the terminal 20 is being moved forward during the slide translatory movement.
  • the guide channel 25 by interfering with the base 41, assumes a position indicated at 46 in Figure 2, releasing the terminal 20 after guiding it to the correct position within the second guide channel 40.
  • a side slot insulating caps 46 which are gravity fed from an inclined feed-in chute 47, in co-operative communication with a vibrating orientator device which may, for example, comprise a helically hollowed ramp wherealong the caps are caused to advance by vibrating the same.
  • the ramp element being cylindrical, and at a predetermined point, the caps may be caused to fall therefrom, before recommencing their advancement until they assume correct orientation.
  • an insulating cap 48 would be inserted, into the foremost portion of the second guide channel 40, thereby as the terminal 20 moves forward under the thrust applied by the piston 38 or by translation of the slide 34, there first occurs the insertion of the terminal into the insulating cap and then, with a further forward movement, the terminal is inserted into a male connector 49 on a base 4 belonging, for example, to a timer 5 which is previously positioned as a direct continuation of said second guide channel 40, which is mounted on the rotatable table 52, positionable in combination with two motors 56,58, adapted for causing movement of the table 52 in vertical and horizontal planes respectively, according to instructions programmed into a computer or processor for piloting the machine.
  • a double clamping holder respectively indicated at 50 and 51 in Figure 1, mounted on the rotary table 52 which enables securement of two devices to be wired, respectively indicated at 53 and 54.
  • the rotary table 52 is mounted on a vertical translating support 55 which is driven by a step motor 56 which allows for the vertical displacements for proper positioning in this direction of the base with respect to the second guide channel for the terminal.
  • That vertical translating support 55 in conjunction with its motor 56 is mounted on a horizontal translating support 57, also equipped with a step driving motor 58.
  • the combination of this device allows, therefore, the progressive positioning of the male connectors present on the devices to be wired in front of the insertion device.
  • the whole assembly is mounted on the machine frame.
  • Figures 6 and 7 illustrate the device which performs the feeding and selection of a wire cross-section sought.
  • the device for feeding and selecting the type of wire to be employed shown in Figure 6 consists of four feeding rollers of which two are indicated and visible in the figure which shows a section through the device itself where they are indicated at 59 and 60.
  • the feeding rollers which are disposed in two consecutive pairs are driven through a pair of gears 61 and 62, respectively, which are in mesh engagement with a single middle pinion gear 63.
  • the pinion 63 is actuated by the gears 61,62, which in turn actuate two other gears, not indicated in the drawings.
  • the advancement device is leaflet No TSA2E of INARCA S.p.A. of Padova, Italy.
  • Said monolithic element 68 can translate vertically owing to the driving effect of a small piston 69 and the stroke length of that piston 69 is such that only one of the two grooves, either 66 or 67, will be aligned to the feeding rollers 59 and 60 thereby only one of the two wires, either 64 or 65, will be moved forward.
  • the wires are in all cases and always picked up from two coils of wire and have the same colour or may have therefore at the most two colours.
  • an encoding station indicated at 70 which utilises an ink writing device where ink is injected through two slots 71 and 72 formed at the passage area of the wires 65 and 64, respectively.
  • That encoding station also programmed by the processor which controls said machine enables the writing of one code on the head and tail of the lead at a suitable distance from the end point where the terminal is connected.
  • the wires 64 and 65 are guided into flexible conduits 73 and 74, respectively, which are formed from metal coils.
  • the wires are guided, as mentioned, by the flexible conduits 74 and 73, to a double movable head generally indicated at 76, composed of a first movable clamping device 77 comprising a small piston 78 which locks the wire 65, if necessary, within the conduit by means of a presser not shown in the figure.
  • An identical second clamping device 79 is arranged below the first and also comprises a pneumatic plunger indicated at 80 which by acting on the wire 64 locks it when necessary.
  • the first clamping device is provided with a lug with-a rack 81 which meshes with a toothed pinion 82 which is engaged by a second rack 83 made fast with the second clamping device 79.
  • the pinion 82 is mounted on a fixed axis relatively to the machine frame, thereby the translational displacement of one of the two clamping devices results in a simultaneous and oppositely directed displacement of the other clamping device.
  • the translation takes place by means of a pneumatic piston 84 whose rod 85 is made fast with the first clamping device 77.
  • the translation of the clamping devices is also allowed by that the flexible conduits 73 and 74 can extend because formed from a metal coil.
  • This first section is followed by a printing and encoding section where the wire is marked with a code which identifies it.
  • This second section is then followed by a switch-over section which enables the leading end of the selected wire to be taken into the cutting and clenching station without the second wire interfering with this operation.
  • the lead head On completion of the stripping, cutting and clenching operation, the lead head is taken into the turret which is equipped with the grip and guide devices which allow the lead now provided with the terminal into the station which carries out mechanically the insertion of the terminal on the base to be wired.
  • the base is mounted on a movable support system which affords the possibility of mounting a base with multiple connectors by progressively taking each of them to a wiring position.
  • the machine is operatively fully dependent on a control and setting processor, on which all the operations and sequence of operations which the machine is to perform are preset, and as also illustrated in the explanatory leaflet No. TSA2E of INARCA S.p.A., of Padova, Italy.
  • the machine can carry out of its own account the whole operation of cutting to size, clenching the end electrical connectors, insulating the same, inserting one end of each lead on a multiple connection base.
  • the machine once it is set, can do without the attendance of an operator excepting for intervention is the event of the machine jamming.
  • the machine is most suitable for repeatitive wiring of multiple bases in large mass production environments.
  • control and actuation systems are formed, in the example shown, from mechanical means and pneumatic actuators which are particularly reliable and fast in operation.
  • control and command means may also be any ones, so long as they are capable of performing the machine programming, controlling, and commanding functions.
  • the materials used may be any ones, as may be the dimensions.
