Definitions

  • the invention relates to the field of winding machines to make a winding of a conductive wire (coil) on a core.
  • the invention addresses the technical field of toroidal coils.
  • Toroidal coils are used in several applications and are generally considered to perform better than coils with differently shaped cores.
  • One of the advantages of toroidal coils is the low leakage of flux due to the closed-loop shape of the core.
  • winding a conductive wire on a toroidal core is a laborious operation.
  • the winding process is complicated by the closed shape of the core which does not allow the wire to turn rapidly around the core, as occurs with known "flyer" winding machines.
  • the realization of the winding is more demanding when the wire has a relatively large section and is difficult to bend and/or when the core has a small size.
  • the winding is carried out with the aid of a machine that facilitates the work but the process remains manual. More specifically, the following winding techniques are known, using semi-automatic machines.
  • a piece of wire is prepared, pre-cut to size i.e. to a length suitable for the extension expected from the toroid core, and said piece of wire is loaded onto a rotating magazine.
  • a length of pre-cut wire is prepared to size, as above, which is loaded onto a fixed winding station.
  • Said fixed station essentially comprises a hook with a rapid vertical up-and-down movement.
  • the core or ring intended to receive the winding is positioned so that the vertical trajectory of the hook passes through the central opening of the ring.
  • the winding procedure with said semi-automatic fixed station is as follows.
  • the operator positions the ring in place, then fixes one end of the metal wire (usually copper) to a suitable anchoring point, manually places the wire over the center of the ring, and operates the hook.
  • the hook grabs the wire and drags it under the ring; at this point, the operator manually releases the wire from the hook to reposition the wire over the ring thus completing a coil around the ring.
  • the operator can activate the hook again to start making a second coil and so on.
  • the winding is performed by hand with the only aid of the hook to pass the wire through the central opening of the ring.
  • CN 213 935 949 U and CN 107 424 839 A disclose machines for winding a conductor wire around a toroidal core.
  • an object of the invention is to automate the winding operation of toroidal coils.
  • a further aspect of the invention is a method for making a toroidal winding according to the claims.
  • a machine comprises a hook arranged to translate along a vertical axis Z and configured to grab the conductor wire, and further comprises a forming arm which is controllable in position on three axes in the space around the toroidal core (or ring) being processed.
  • the forming arm has a controllable and programmable position in the space around a housing area of the core being processed.
  • the invention provides for the making of a toroidal winding in a completely automated manner by means of the cooperation between said hook, said forming arm, and the core support.
  • the latter is arranged to rotate by an appropriate angular pitch following the formation of the coils.
  • the main advantage of the invention is the provision of a machine which allows automating a process carried out until now in an essentially manual way, with consequent advantages in terms of productivity, cost reduction and winding precision.
  • the forming arm movable in space, controlled on three axes substantially replaces the manual work so far carried out by the operator.
  • toroidal core as known identifies a closed-loop core, also simply referred to as "donut-shaped”.
  • a machine according to the invention can comprise a control system configured to control the hook, the arm, and the rotating support with the following coil winding procedure:
  • running end indicates the wire portion which is actively guided to form the coils in analogy with the terminology used in the field of knots.
  • the forming arm can be provided with a bearing or wire guide roller to obtain the desired dragging effect on the conductor wire.
  • a bearing or wire guide roller to obtain the desired dragging effect on the conductor wire.
  • said bearing is rotatable with respect to the arm and has a central groove adapted to receive the conductor wire so that, when the wire is accommodated in the groove, the arm can move the wire in space and bend it around the core.
  • the forming arm comprises two wire guide bearings located on opposite sides of the arm itself.
  • the bearing or bearings is/are at the end of the arm.
  • the hook has a head which is shaped to grab the conductor wire, preferably with a down facing slot.
  • the forming arm is controllable and programmable in position on three axes, i.e., along the vertical axis Z and along a further pair of axes X, Y which define a horizontal plane. More precisely, the axes X, Y, and Z identify a system of orthogonal axes in the space.
  • the position of the forming arm is controllable independently on each of said three axes. The control is preferably obtained by combining the translation on suitable guides arranged along the axes.
  • the machine comprises a first column-shaped structure which contains the hook and which comprises, at the top, the rotating support for the core; a second structure which carries the forming arm, said structure comprising three linear guides oriented according to orthogonal axes X, Y and Z which allow the control of the forming arm in the space.
  • the machine can comprise, in a first embodiment:
  • the machine comprises, for controlling the forming arm on three axes:
  • the machine comprises a pair of grippers located close to the housing of the core.
  • Each one of said gripper is adapted to clamp one end of a piece of conductor wire, to define an anchoring and a starting winding point.
  • a pair of such grippers is provided, which are arranged above and on opposite sides, i.e. respectively right and left, with respect to the housing for the core.
  • Said grippers preferably have controlled opening and closing, for example by means of a pneumatic control.
  • clockwise winding or counterclockwise winding refers to the direction of rotation of the core as the winding proceeds, conventionally seen from above.
  • the two grippers are advantageously movable according to at least one horizontal axis perpendicular to the forming arm, to allow the grippers to be moved away from the winding area, if required, and to adjust the position of the anchoring point.
  • a degree of freedom can be achieved by mounting each gripper on a pneumatic slide.
  • a variant including a single gripper can also be suitable for making both clockwise and counterclockwise windings by providing the single gripper with mobility on two axes or preferably on three axes so that the gripper can be positioned on both sides of the core housing and forming arm.
  • the winding procedure can comprise the following initial steps:
  • a notable feature is the starting of the winding from within the toroidal core.
  • a winding method according to the invention can generally comprise the following steps:
  • the steps listed above are automatically carried out in sequence by the machine until the completion of a preset number of winding coils. Moreover, the steps listed above can be carried out after the winding starting step described at a) and b) above.
  • a machine according to the invention can be further configured to automatically load and cut to programmable size the piece of wire required for the winding, and/or to automatically load the toroidal core.
  • the machine of the invention can be configured to integrally produce and eject a toroidal coil formed in a fully automatic manner.
  • the machine can be configured to eject a coil which is ready for assembly and for the subsequent steps of the production process.
  • the further process steps may comprise electrical testing and mounting in an electromechanical device, e.g. hosting a toroidal transformer with winding created according to the invention.
  • Fig. 1 shows an embodiment of a machine, not part of the invention, in which the essential details are as follows:
  • the forming arm 8 is controllable on the three axes X, Y, and Z by combining suitable translations of base 2, head 4, and carriage 6, respectively along the guides 3, 5, and 7.
  • Fig. 1 indicates, in addition to the orthogonal axes, the ascent and descent direction Z1 of hook 11.
  • the double arrow W indicates the possibility of rotation around axis Z of the core-holder flange 10.
  • Motor 14 imparts a rotation to the drive flange 13; the upper flange 10 is made integral with said drive flange 13 by means of tubes 16.
  • FIG. 2 The conductor wire F and a core represented by a toroidal ring T anchored to flange 10 by means of two jaws 17 are shown.
  • the wire portion F1 located under the core T can be defined as a "running end" of the wire, in the sense that it is the part of wire actively participating in the formation of the coils, being spatially guided by the forming arm 8 and the hook 11 as explained below.
  • the forming arm 8 is provided with two rollers 19 at one end thereof, arranged on opposite sides of the arm itself. Said rollers 19 are rotatable and provided with a central groove 51 ( Fig. 4 ) adapted to accommodate the wire F.
  • Flange 10 is rotatable around axis Z being guided by bearings 20 on a circular guide profile 21.
  • Said profile 21 has a front discontinuity to allow the passage of the forming arm 8.
  • the drive flange 13 has a central hole 22 which allows the passage of hook 11.
  • the figures indicate the oriented axes X, Y, and Z.
  • a displacement will be referred to as positive or negative in accordance with the direction shown in the figures.
  • the forming arm 8 retracts in the direction Y (Y-negative displacement), raises itself above the ring T, and moves forward in the direction Y (Y-positive displacement) substantially turning around the core T.
  • the running end F1 of the conductor wire follows the forming arm 8 resting on roller 19.
  • the forming arm 8 essentially bends the wire against the outer surface of ring T ( Figs. 3-5 ).
  • roller 19 in Fig. 2 is in front of the wire F (with respect to the oriented direction Y), which allows the forming arm 8 to "pull" the wire in the Y-negative direction.
  • the roller 19 is located behind the wire, so that the forming arm 8 can "push" the wire in the Y-positive direction to reach the condition shown in Fig. 5 .
  • the arm proceeds in the Y-positive direction bringing the running wire end above the center of ring T and reaching the configuration in Fig. 5 . From this position, the running wire end can be grabbed by hook 11 as in Fig. 6 and dragged downwards passing through the core T as shown in Figs. 7 and 8 .
  • the forming arm 8 From the position in Fig. 8 , the forming arm 8 returns under the ring T, moves with roller 19 in front of the wire, and picks up the wire F, all due to a three-axis control ( Figs. 8-9 ).
  • the system can start the formation of a new turn ( Figs. 10 , 11 ).
  • Flange 10 rotates and angularly positions the core T for the formation of the new coil.
  • the forming arm 8 substantially performs a "forth-and-back" winding cycle synchronized with the hook 11 and with the rotation of the flange 10, thus obtaining the desired winding of the coils.
  • FIGs. 12 to 23 and the respective details in Figures 12A to 23A represent an embodiment of the invention.
  • Machine 100 comprises, similarly to the version described above, a forming arm 8 which is movable and programmable on 3 axes X, Y, Z and carries at its end a roller 19 or other device adapted to accommodate the conductor wire F.
  • the control on the 3 axes X, Y, and Z is obtained by different means but is conceptually equivalent to that in Figs. 1-11 .
  • the machine 100 comprises a head 30 translating along guides 34 according to the axis Y.
  • the forming arm 8 is mounted inside a carriage 31 which is associated with head 30 and is controlled according to the axis Z with a fixed screw - movable nut screw mechanism.
  • the control along the axis X is given by a system which extracts or retracts the forming arm 8 with respect to carriage 31, for example with a rack.
  • the mechanism which moves carriage 31 comprises, in more detail, a screw 32 which is moved by a motor mounted to the rear of the head 30, and which drives the screw 32 by means of a transmission, for example a belt transmission housed in the upper casing 33.
  • Screw 32 engages a nut screw which is integral with the carriage 31 so that the rotation of screw 32 precisely controls the elevation with respect to the axis Z of carriage 31, and therewith, of the forming arm 8.
  • the forming arm 8, in this second example, comprises a single end roller 19 instead of a pair of rollers as in the previous version.
  • Figs. 12-23 The peculiarity of the version in Figs. 12-23 is given by the presence of two grippers 28, 29 which are placed on the sides of the housing of the toroidal core T and therefore on the sides of the working area of the forming arm 8. Said grippers 28, 29 are adapted to clamp one end of a piece of conductive wire F to define a fixed wire anchoring and a winding starting point.
  • Each of the two grippers 28, 29 is associated respective with a pneumatic slide 40, 41 capable of moving the gripper according to the axis Y ( Fig. 12 ).
  • each gripper is mounted on an actuator 42, 43 which controls the opening and closing thereof ( Fig. 12A ). The movement along the axis Y, given by the pneumatic slides 40 and 41, allows the grippers 28, 29 to be moved away from the winding area when required.
  • the grippers 28 and 29 can be defined to be right and left by looking at them from the top and in the positive direction X (extension direction of the forming arm 8).
  • a variant with a single gripper could equally make clockwise and counterclockwise windings, providing a single gripper capable of selective positioning in the place of the gripper 28 or in the place of the gripper 29.
  • the single gripper can be provided with a programmable position on at least the axes Y and Z and preferably on all three axes X, Y, Z. It is noted that the vertical degree of freedom (axis Z) allows the gripper to overcome forming arm 8, i.e. to move on the right or left thereof without interfering with the winding cycle.
  • rotating flange 10 for supporting the toroidal core T
  • hook 11 with a shaped head 15 for grabbing the conductor wire F
  • jaws 17 for clamping the core T.
  • Said jaws 17 define the housing which accommodates the toroidal core T.
  • Fig. 12A shows the end E of the conductor wire F which is engaged in the right gripper 28.
  • the conductor wire F is engaged in the recess 50 of the shaped head 15 of hook 11.
  • the right clamp 28 is used to anchor the end of the conductor wire since the winding is counterclockwise as indicated by arrow W in the figure.
  • the left gripper 29 would be used in an analogous manner.
  • the portion of conductor wire F which is spatially dragged or guided from time to time by the forming arm 8 and hook 11 can be referred to as the running end F1 of the wire.
  • Fig. 13 the hook 11 is lowered by dragging the wire F therewith and starting the formation of a first coil around the core T. Note the coil forming process starts from within the core T.
  • Fig. 14 the forming arm 8 moves into position to engage the wire F under the core T. Note the lowering of the carriage 31 along the axis Z (controlled by the screw 32) and the extension of the forming arm 8 outside said carriage 31. By means of a combination of movements along the axes X and Y, the forming arm 8 moves with the head roller 19 in front of the wire F. The conductor wire F is engaged in the circumferential groove 51 of roller 19.
  • Fig. 15 the forming arm 8 retracts into carriage 31 in the negative direction X; the roller 19 drags and bends the wire F backwards, bringing it towards the exterior of the core T.
  • Fig. 16 the forming arm 8 rises along Z and forms the outer part of the coil around the core T.
  • Fig. 17 the forming arm 8 extends out of carriage 31 in the X-positive direction and pushes the wire F over the central hole of the core T into a position which is reachable by the hook 11.
  • the symbol S indicates the coil being formed around the toroidal core T.
  • Fig. 18 the wire F is hooked and dragged downwards by hook 11 thus completing the formation of a coil around the core T.
  • the forming arm 8 remains extended to define a sliding point of the wire F in front of the core T.
  • Fig. 19 the forming arm 8 moves back and the hook 11 descends thus substantially completing the coil S1.
  • the wire F passing through the opening of the core T, remains bent in a U-shape around the head of the hook due to its rigidity (being quite thick).
  • flange 10 performs a rotation to prepare the core T for the formation of another coil.
  • the rotation of the flange 10 is counterclockwise when viewed from the top.
  • the gripper 28 opens (controlled by the actuator 42) releasing the end E of the conductor wire. This is possible because the conductor wire is now hooked to the core T by the coil S1 wound around the core.
  • Figs. 21-23 the forming arm 8 generates a second coil S2 on the core T after the rotation thereof.
  • the forming arm 8 is arranged to engage the wire F under the core T.
  • the forming arm then pushes the wire F forward to allow the engagement by the hook 11 (similar condition to Fig. 18 ) and to continue the sequence.
  • Fig. 22 shows that the gripper 28 leaves the winding area due to the slide 40. This is possible because the wire is held by the coils already wound around the core T.
  • the process is repeated until the formation of a desired number of coils, i.e. until the winding is completed.
  • the core T can be repositioned to carry out another winding on a different portion of the core itself, again with the forming arm 8, or the core T can be moved to another point of the machine for finishing operations of the terminals, if needed.
