  • a grommet assembly apparatus for assembling grommets on leads, the apparatus comprising a grommet receiving device comprising a hollow sleeve having a cavity extending therethrough for receiving a lead or wire therein, an outer surface of the tube for receiving a grommet elastically compressed thereagainst for assembly onto the lead, the apparatus further comprising a pin insertable in the wire receiving cavity of the hollow sleeve for assisting assembly of the grommet onto the outer surface of the hollow sleeve, the pin having a tapered leading end in order to guide insertion of the pin through the grommet, wherein the pin leading end is insertable into the sleeve from the wire receiving end thereof.
  • air may be blown out of the sleeve cavity in order to assist pushing of the grommet over the pin until abutment of the grommet against a stop, and subsequent insertion of the sleeve into the grommet central cavity causing resilient expansion thereof.
  • the pin device may be provided in alignment with an end of a grommet supply device, such as a grommet supply channel, such that the pin device can pick the grommet directly from the supply device and insert it directly onto the grommet expansion sleeve.
  • a grommet supply device such as a grommet supply channel
  • a grommet assembly apparatus 2 is shown mounted on a base 4 and upstanding vertically (along the Y axis). The horizontal axis is defined as the axis X.
  • a conveyor apparatus 6 is also fixed to the base 4 of a harness making machine via the support 8.
  • the conveyor system 6 has a plurality of grippers 10 for gripping and conveying leads or wires 12 of electrical or optical cables.
  • the grippers 10 are conveyed in a direction Z perpendicular to the X and Y directions, for transporting the wires 12 to various wire processing stations of the harness making machine, such as stations for cutting the wires ends, stations for crimping terminals to the wires ends, stations for inserting the wires ends into connectors housings etc.
  • One of the wire processing stations is the grommet assembly apparatus 2 for positioning grommet seals on the wire ends for the purpose of sealing the wires in corresponding cavities of a connector housing.
  • a grommet 14 is shown assembled onto an end 15 of the wire 12.
  • the grommet assembly apparatus 2 comprises a fixed structure 16 mounted on the base 4. Fixed to the structure 16 is a primary motor 18 that drives a piston or rod 20 in the horizontal direction X. A slide 22 is also mounted in a fixed manner to the structure 16. A gripper device 24 comprising a support structure 25 and movable jaws 26,27 is fixed to the primary piston 20. The gripper device 24 is therefore movable in the X direction by means of the motor 18. The movable jaws 26,27 are movable in a vertical direction towards and away from each other by means of a motor (not shown) mounted on the gripper support 25.
  • the upper jaw 26 is shown separated from the gripper device, but in fact it is mounted within a portion of the support 25 that forms a single assembled structure movably fixed to the rod 20.
  • the gripper support 25 is slidably mounted on a slide 30 extending in the X direction and rigidly fixed to the apparatus support 16.
  • a grommet mounting device 32 comprises a mounting device support 35 that is slidably mounted in the X direction on the fixed slide 22, the device further comprising a grommet receiving member 36 rotatably mounted about a Z axis to the device support 34 as indicated by the mounting portion 38.
  • a secondary motor 40 is mounted in a fixed manner to the grommet mounting device support 34, and drives a secondary piston or rod 42 in the X direction.
  • the secondary rod 42 is secured to the gripper support 25 such that the gripper device 24 and the grommet mounting device 32 are relatively slidable in the X direction with respect to each other and with respect to the apparatus fixed structure 16.
  • the grommet assembly apparatus further comprises a grommet transport device having a grommet supply of feed channel 44 that feeds grommets 14 to an end 46 of the channel 44 for mounting on the grommet receiving member 36.
  • the grommets 14 are positioned vertically in the feed channel 44 proximite the end 46, such that central channels 48 traversing the grommets 14 extend in the Y direction.
  • the apparatus further comprises a grommet transfer device 50 for transferring and loading grommets 14 on to the mounting device 32.
  • the transfer device 50 comprises a motor 52 that drives a grommet transfer element 54 in the vertical direction Y.
  • the transfer element 54 is provided in alignment with a grommet 14 at the end portion 46 of the feed channel 44.
  • the transfer element 54 is shown comprising a pin 56 extending to a free end 58, and a stop 60 concentrically surrounding the pin 56 at a certain distance remote from the free end 58 for providing an abutment surface to limit insertion of the grommet 14 along the pin 56.
  • the free end 58 is pointed and extends towards the stop 60 in a tapered or conical manner, thereby providing a smooth guide or insertion tip 62 for smoothly inserting and locating in the central cavity 48 of the grommet 14.
  • the rotatable grommet receiving mounting device 36 comprises a chamber 64 positioned centrally within a housing 66, the device further comprising a grommet expansion sleeve 68 attached to the housing 66 and forming a cavity 70 extending therethrough in communication with the chamber 64.
  • the cavity 70 is a wire receiving cavity which is also adapted to receive the transfer pin 56 therein as shown in figures 9 and 10, during mounting of the grommet 14 on the expansion sleeve 68.
  • the chamber 64 is supplied with compressed air through a supply channel 72 which is connected to a flexible tube (not shown) for supplying the compressed air into the chamber 64.
  • the compressed air may be supplied intermittently during operation by automatically regulated control valves.
  • a grommet 14 in abutment against the end 46 of the feed channel 44 is in alignment with the transfer element 54.
  • the transfer element 54 is driven in the Y direction towards to the grommet 14 whereby the tip 58, 62 of the pin 56 is inserted partially into the grommet central cavity 48.
  • the movement of the pin 56 and partial engagement in the grommet cavity 48 pushes the grommet 14 through the exit cut-out 78 in the bottom wall 80 of the feed channel 44.
  • the grommet outer diameter is slightly larger than the cut-out 78 such that the grommet remains within the feed channel 44 until pushed by the transfer element.
  • the transfer element 54 is driven along the Y axis until the grommet 14 abuts the stop 60 and the expansion sleeve 68 is subsequently inserted between the grommet and the pin 56.
  • the grommet is thereby elastically expanded over the outer surface 84 of the expansion sleeve 68.
  • a recess 90 extends into the transfer element 54 between the pin 56 and a concentric wall 88 that forms the abutment shoulder 60 in order to allow extension of the expansion sleeve 68 therein.
  • the concentric wall 88 may be provided with a cavity 89 to allow air to escape from the recess or cavity 90 if necessary.
  • the primary rod 20 and the secondary rod 42 are both in retracted positions, and the grommet receiving member 36 is in the vertical position in alignment with the transfer element 54.
  • a grommet 14 is then mounted on the expansion sleeve 68 as previously described with reference to figure 9 and 10, and as depicted in figure 2.
  • the grommet receiving member 36 is rotated 90 degrees to the horizontal position in alignment with a wire 12 carried by the conveying system to the grommet assembly apparatus.
  • the expansion sleeve 68 is received within a U-shaped recess 92 of a retention wall 94 (see figure 8a) that serves to retain the seal in an axial position along the X axis with respect to the gripper device 24.
  • the U-shaped recess 92 of the retention wall 94 has a smaller radius than the grommet 14, such that when the expansion sleeve 68 is retracted with respect to the retention wall 94, the grommet slides off the expansion tube.
  • the jaws 26,27 are closed towards to each other.
  • the jaws 26,27 are provided with a funnel shaped wire guide surface 96 that serves to guide the end 15 of the wire 12 into the expansion sleeve cavity 70 as shown in figure 5. Insertion of the wire end 15 into the cavity 70 is effected by activating the motor 18 and driving the primary road 20 to an extended position. Both the gripper device 24 and the mounting device 32 slide on their slides 30,22 respectively.
  • the secondary rod 42 is driven into the extended position by the secondary motor 40 such that the mounting device 32 is retracted relative to the gripper device 24, such that the retention wall 94 of the gripper pulls the grommet 14 off the expansion sleeve and onto the wire 12.
  • the jaws 26,27 are moved to the open position as shown in figure 6, and the primary motor 18 subsequently driving the primary rod 20 to the initial retracted position such that the wire end 15 is freed.
  • the wire end can then be moved by the conveyor system and a new wire presented before the grommet assembly apparatus.
  • the secondary rod 42 is also driven to the retracted position by the secondary motor 40, and the grommet receiving member 36 rotated to the vertical position such a new cycle may commence.
