Definitions

  • the present invention relates to a method of winding several turns of wire on a core, in particular for winding deflection rings for cathode ray tubes. It also relates to a machine for implementing the method according to the invention and a winding specially obtained using the method of the invention.
  • electrical wire windings coated with insulation comprising several turns of wire wound on a magnetic core.
  • deflection rings which are constituted by a magnetic ferrite core having substantially the shape of a truncated cone flared in a bowl, on which core are wound a bundle of turns.
  • the ferrite ring is initially divided into two parts, and each half-core thus having an open structure can be wound on automatic winders, each half-ring being able to be held on the machine. wind by one of its side edges.
  • the turns are wound substantially along radial planes, that is to say, passing through the axis of the truncated cone of the ring.
  • Such an orientation of the turns is not advantageous on the electromagnetic level, not corresponding to the best deflection efficiency of the cathode beam.
  • the object of the invention is to allow, without reducing the working speed of the winders of a machine, to obtain wound parts, in particular as deflection rings for cathode ray tubes, in which each wound turn has been according to the optimal orientation calculated for the function that the wound piece must fulfill.
  • said turns may be inclined on radial planes symmetrically on either side of the median plane of each half-ring with two bundles of symmetrical turns clearly spaced from the median plane on the small edge of the bowl and on the contrary substantially contiguous on the large edge.
  • the method of the invention making it possible to reach these objects is characterized in particular in that the winding plane of each turn is determined by the position in rotation ⁇ of the segment to be wound around a first axis X and by the rotational position d of the reel around a second axis Y which obliquely intersects the first axis X in the vicinity of the segment to be wound, the reel rotating around a third axis Z directed obliquely to the axis Z and also passing through the segment to be wound, which is fixed by its median plane, and the rotational positions ⁇ , ⁇ of the support and of the reel being controlled in order to obtain the desired successive planes of winding the turns around the core .
  • the axes X and Y are chosen to be fixed relative to one another and directed substantially orthogonally, as are the axes Z and Y.
  • each core to be wound is fixed, such as a substantially frustoconical ferrite half-ring, on its support, substantially in its median plane and on its small edge, and a perfectly symmetrical winding of turns inclined with respect to this median plane by choosing winding programs with symmetrical angles ⁇ and ⁇ .
  • conjugation means are advantageously constituted by a microprocessor or computer memorizing the numbers of turns to be wound around the core for each value of the angles ⁇ and ⁇ determined conjugate above.
  • winding program thus established then controls by any known means existing in the art and within the reach of the technician the various motors of the machine, namely the winding motors and the stepping motors for determining the angle ⁇ of rotation of the support around the X axis and the stepper motors for determining the angle of rotation of the column around the Y axis.
  • the machine comprises a frame 1 with a base 2 supporting an upright 3 in which are mounted two supports 4 1 , 4 2 orientable at an angle a respectively around axes X 1 and X 2 substantially horizontal like the plane of the base 2 in the example illustrated.
  • the supports 4 1 , 4 2 are driven by an electric motor with stepping control 5 whose output shaft 6 drives two pulleys 7 1 , 7 2 connected by a belt 8.
  • the pulleys 7 1 , 7 2 are wedged on the shafts 9 1 , 9 2 for driving the support arms 4 i , 4 2 .
  • the machine further comprises a column 11 which supports, in the example illustrated, two conventional reels whose arms marked 12 1 , 12 2 are driven in rotation and simultaneously around the two parallel axes Z i , Z 2 , horizontal in the illustrated embodiment.
  • the arms 12 1 , 12 2 are driven by a motor, the cover of which can be seen at 13.
  • the whole of the column 11 is mounted rotating at an angle ⁇ around a fixed axis Y relative to the frame and substantially vertical, that is to say perpendicular to the base 2 in the example illustrated .
  • the rotation of the entire column around the Y axis is obtained by means of an electric motor with stepping drive visible at 14 in FIG. 2.
  • the Y axis passes substantially at the locations where the parts 4 1 , 4 2 can be presented at the end of the supports to be wound such as the frustoconical ferrite half-ring illustrated at 15 and mounted fixed on the support 4 2 .
  • the winding arms 12 1 , 12 2 are also positioned on the column 11 so that the winding plane cuts the piece to be wound, allowing the winding.
  • the circle described by the winding end of the arm 12 1 rotating around its axis of rotation Z i has materialized , this circle 16 obviously being contained in the winding plane.
  • Fig. 8 shows, seen from the X axis, the angle a of rotation of the arm 4 supporting the part 15.
  • the angle ⁇ for ease of reference can be identified with respect to a straight line A 'A vertical, parallel to the Y axis and passing through the X 1 and X 2 axes.
  • fig. 9 represents, seen from the axis Y the angular orientation d of the column 11 around said axis Y.
  • the angle ⁇ can be located from the line B 'B which is none other in the example illustrated as the projection on the plane of the base 2 of the axes X I , X 2 .
  • the half-ring 15 will be supported at the end of the support 4 1 , 4 2 substantially in its median plane and on its small edge.
  • the fixing can be done by means of a comb 17 made of plastic material, bonded to the frustoconical ferrite half-ring 15 and comprising teeth 18 in which the coiled turns 19 will be housed, thus ensuring good positioning. and avoiding any further slipping.
  • the support arm 4 2 may be provided at its end with a clamp which will receive the middle part of the comb.
  • the core constituted by a ferrite half-ring 21 was held by a lug 22, for example glued in the vicinity of an end edge of the half-ring 21, and on the half-ring thus held, coils were wound by means of winding arms such as 12 1 , 12 2 in radial planes passing through the axis 24 of the half-ring 21. These different radial winding planes were obtained by pivoting the arms reels around the axis 24 of the ring held fixed.
