Description

La présente invention a pour objet un procédé et une machine de bobinage permettant de réaliser un bobinage amélioré notamment des bagues de déviation pour tubes cathodiques.The subject of the present invention is a method and a winding machine making it possible to produce an improved winding, in particular deflection rings for cathode ray tubes.

Pour de nombreux appareils électromagnétiques, on utilise des bobinages de fils électriques revêtus d'isolant comprenant plusieurs spires de fil enroulé sur un noyau magnétique.For many electromagnetic devices, windings of electrical wires coated with insulation are used comprising several turns of wire wound on a magnetic core.

Ainsi, pour les tubes cathodiques, on utilise des bagues de déviation qui sont constituées par un noyau magnétique en ferrite ayant sensiblement la forme d'un tronc de cône évasé en cuvette, sur lequel noyau sont enroulées serrées un faisceau de spires. Pour permettre le bobinage sur des machines à bobiner, la bague en ferrite est initialement divisée en deux parties, et chaque demi-noyau présentant ainsi une structure ouverte peut être bobiné sur des bobineuses automatiques, chaque demi-bague pouvant être tenue sur la machine à bobiner par une de ses tranches latérales.Thus, for cathode ray tubes, deflection rings are used 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 tightly a bundle of turns. To allow winding on winding machines, 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.

Dans les bobinages actuellement réalisés à la machine, les spires sont enroulées sensiblement suivant des plans radiaux, c'est-à-dire en passant par l'axe du tronc de cône de la bague. Une telle orientation des spires n'est pas avantageuse sur le plan électromagnétique, ne correspondant pas au meilleur rendement de déviation du faisceau cathodique.In the windings currently produced by machine, 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.

Bien sûr, on peut chercher à améliorer les performances des bagues de déviation en bobinant chaque spire sur chaque demi bague sous les meilleures orientations, et par exemple en exécutant un tel bobinage à la main. Il s'agirait cependant là d'opérations extrêmement longues et coûteuses peu applicables industriellement.Of course, one can seek to improve the performance of the deflection rings by winding each turn on each half ring under the best orientations, and for example by performing such winding by hand. However, these are extremely long and costly operations which are not industrially applicable.

L'objet de l'invention est de permettre sans réduire la vitesse de travail des enrouleurs d'une machine d'obtenir des pièces bobinées, telles notamment que des bagues de déviation pour tubes cathodiques, dans lesquelles chaque spire bobinée l'a été suivant l'orientation optimale calculée pour la fonction que la pièce bobinée doit remplir.The object of the invention is to allow without reducing the working speed of the reels of a machine to obtain wound parts, such as in particular deflection rings for cathode ray tubes, in which each wound turn has been in the optimal orientation calculated for the function that the wound piece must fulfill.

Ainsi, par exemple, s'agissant de bobinages de déflexion pour tubes cathodiques présentant des spires enroulées sur chaque demi-bague en forme de tronc de cône évasé en cuvette, lesdites spires pourront être inclinées sur des plans radiaux symétriquement de part et d'autre du plan médian de chaque demi-bague avec deux faisceaux de spires symétriques nettement écartés du plan médian sur la petite tranche de la cuvette et au contraire sensiblement jointifs sur la grande tranche.Thus, for example, in the case of deflection windings for cathode ray tubes having turns wound on each half-ring in the form of a truncated cone flared in a bowl, 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.

Le procédé de l'invention permettant d'atteindre ces objets se caractérise notamment en ce qu'on maintient le noyau à recouvrir du bobinage sur un support orientable à chaque instant autour d'un axe X, on monte chaque enrouleur de façon que son bras d'enroulement puisse tourner autour dudit noyau et autour d'un axe Z dirigé obliquement par rapport à un axe Y, lui-même dirigé obliquement par rapport audit axe X, et l'on choisit et pilote à chaque instant la position en rotation α dudit support autour dudit axe X et la position en rotation β de l'axe Z autour dudit axe Y pour obtenir les différents plans successifs voulus d'enroulement des spires autour du noyau.The method of the invention making it possible to achieve these objects is characterized in particular in that the core to be covered with the coil is kept on a support that can be oriented at all times around an X axis, each reel is mounted so that its arm winding can rotate around said core and around an axis Z directed obliquely with respect to an axis Y, itself directed obliquely with respect to said axis X, and the rotational position α is chosen and controlled at all times of said support around said axis X and the rotational position β of the axis Z around said axis Y in order to obtain the various desired successive planes of winding of the turns around the core.

De préférence, de façon pratique, les axes X et Y sont choisis fixes l'un par rapport à l'autre et dirigés sensiblement orthogonalement, de même que les axes Z et Y.Preferably, in practice, the axes X and Y are chosen to be fixed relative to each other and directed substantially orthogonally, as are the axes Z and Y.

Selon une autre caractéristique du procédé de l'invention, on fixe chaque noyau à bobiner, tel qu'une demi-bague ferrite sensiblement tronconique, sur son support, sensiblement dans son plan médian et sur sa petite tranche, et l'on réalise un bobinage parfaitement symétrique de spires inclinées par rapport à ce plan médian en choisissant des programmes d'enroulement à angles α et β symétriques.According to another characteristic of the method of the invention, 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 angles α and β symmetrical.

L'invention se rapporte également à une machine permettant la mise en oeuvre du procédé mentionné, cette machine se caractérisant en ce qu'elle comporte :

  • - un bâti,
  • - au moins un support de noyau orientable selon un angle α autour d'un axe X fixe par rapport au bâti,
  • - au moins une colonne supportant au moins un enrouleur monté tournant sur ladite colonne autour d'un axe Z fixe par rapport à ladite colonne,
  • - ladite colonne étant montée tournant selon un angle β dans ledit bâti autour d'un axe Y fixe par rapport audit bâti.
  • - lesdits axes X, Y et Z étant dirigés obliquement les uns par rapport aux autres. De façon pratique et avantageusement, les axes X et Y d'une part, et Y et Z d'autre part, sont disposés sensiblement orthogonalement.
The invention also relates to a machine allowing the implementation of the mentioned process, this machine being characterized in that it comprises:
  • - a frame,
  • at least one core support which can be oriented at an angle α around an axis X which is fixed relative to the frame,
  • at least one column supporting at least one reel mounted rotating on said column around a fixed axis Z relative to said column,
  • - Said column being mounted rotating at an angle β in said frame around a fixed Y axis relative to said frame.
  • - Said axes X, Y and Z being directed obliquely with respect to each other. Conveniently and advantageously, the axes X and Y on the one hand, and Y and Z on the other hand, are arranged substantially orthogonally.

Selon une autre caractéristique de la machine objet de l'invention, elle comprend en outre :

  • - des premiers moyens de commande permettant de choisir à chaque instant la position angulaire α et de faire tourner pas à pas ledit support de noyau autour de l'axe X,
  • - des seconds moyens de commande permettant de choisir à chaque instant la position angulaire β et de faire tourner pas à pas ladite colonne autour dudit axe Y,
  • - et des moyens de conjugaison desdits premier et second moyens de commande pour obtenir les différents plans successifs voulus d'enroulement des spires autour du noyau.
According to another characteristic of the machine which is the subject of the invention, it further comprises:
  • - first control means making it possible to choose the angular position α at all times and to rotate said core support step by step around the axis X,
  • second control means making it possible to choose the angular position β at each instant and to rotate said column step by step about said axis Y,
  • - And conjugation means of said first and second control means to obtain the various successive desired planes of winding the turns around the core.

Ces moyens de conjugaison sont avantageusement constitués par un micro-processeur ou ordinateur mémorisant les nombres de spires à enrouler autour du noyau pour chaque valeur des angles o( et β déterminés conjugués précités. Le programme d'enroulement ainsi établi commande alors selon tout moyen connu existant dans la technique et à la portée du technicien les différents moteurs de la machine, à savoir les moteurs d'enrouleurs -et les moteurs pas à pas de déterminatoins de l'angle α de rotation du support autour de l'axe X et les moteurs pas à pas de détermination de l'angle β de rotation de la colonne autour de l'axe'Y.These 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 o (and β determined conjugate above. The winding program thus established then controls by any known means existing in the technique and within the reach of the technician the different motors of the machine, namely the reel motors -and the stepper motors of determinatoins of the angle α of rotation of the support around the X axis and the stepper motors for determining the angle β of rotation of the column around the Y axis.

  • - L'invention apparaîtra plus clairement à l'aide de la description qui va suivre faite en référence aux dessins annexés dans lesquels :- The invention will appear more clearly with the aid of the description which follows, made with reference to the appended drawings in which:

  • - La figure 6 montre comme la figure 4 une demi-bague ferrite bobinée selon l'art antérieur.- Figure 6 shows like Figure 4 a ferrite half-ring wound according to the prior art.
  • - La figure 7 montre comme la figure 5 la demi-bague de la figure 6.- Figure 7 shows like Figure 5 the half-ring of Figure 6.
  • - Les figures 8 et 9 sont deux schémas angulaires illustrant comment peuvent être mesurés les angles α et β de rotation respectivement du bras support de la machine et de la colonne support des enrouleurs.- Figures 8 and 9 are two angular diagrams illustrating how the angles α and β of rotation can be measured respectively of the support arm of the machine and the support column of the reels.

Selon le mode de réalisation illustré aux dessins, la machine comprend un bâti 1 avec un socle 2 supportant un montant 3 dans lequel sont montés deux supports 41 , 42 orientables selon un angle α respectivement autour d'un axe X1 et X2 sensiblement horizontaux comme le plan du socle 2 dans l'ex- emple illustré. Pour leur rotation autour des axes X1 et X2, les supports 41 , 42 sont entraînés par un moteur électrique à commande pas à pas 5 dont l'arbre de sortie 6 entraîne deux poulies 71, 72 reliées par une courroie'8. Les poulies 71, 72 sont calées sur les arbres 91, 92 d'entraînement des bras supports 41, 42.According to the embodiment illustrated in the drawings, 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 α respectively around an axis X 1 and X 2 substantially horizontal as the plane of the base 2 in the former e mple shown. For their rotation around the axes X 1 and X 2 , 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 fixed on the shafts 9 1 , 9 2 for driving the support arms 4 1 , 4 2 .

En 10, on a repéré un volant permettant le calage manuel de l'angle α et monté en bout d'axe du moteur 5.At 10, a flywheel was identified allowing manual setting of the angle α and mounted at the end of the axis of the motor 5.

La machine comporte d'autre part une colonne Il qui supporte dans l'exemple illustré.deux enrouleurs classiques dont les bras repérés 121, 122 sont entraînés en rotation et simultanément autour des deux axes parallèles Z1, Z2, horizontaux dans l'exemple de réalisation illustré. Les enrouleurs 121, 122 sont entraînés par un moteur dont on aperçoit le capot en 13.The machine further comprises a column II 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 1 , Z 2 , horizontal in the illustrated embodiment. The reels 12 1 , 12 2 are driven by a motor, the cover of which can be seen at 13.

D'autre part, l'ensemble de la colonne 11 est monté tournant selon un angle β autour d'un axe Y fixe par rapport au bâti et sensiblement vertical, c'est-à-dire perpendiculaire au socle 2 dans l'exemple illustré. La rotation de l'ensemble de la colonne autour de l'axe Y est obtenue grâce à un moteur électrique à entraînement pas à pas visible en 14 à la figure 2.On the other hand, the whole of the column 11 is mounted rotating at an angle β 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.

On notera que l'axe Y passe sensiblement à l'endroit où peut être présentée en bout des supports 41, 42 la pièce à bobiner telle que la demi-bague ferrite tronconique illustrée en 15 montée fixée -sur le support 42.It will be noted that the axis Y passes substantially at the point where the piece to be wound at the end of the supports 4 1 , 4 2 can be presented such as the frustoconical ferrite half-ring illustrated in mounted mounting -on the support 4 2 .

Evidemment, les bras bobineurs 121, 122 sont également positionnés sur la colonne 11 de façon que le plan d'enroulement coupe la pièce à bobiner, permettant le bobinage. En 16, on a matérialisé le cercle décrit par l'extrémité d'enroulement du bras 121 tournant autour de son axe de rotation Z1, ce cercle 16 étant évidemment contenu dans le plan d'enroulement.Obviously, 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. At 16, the circle described by the winding end of the arm 12 1 rotating around its axis of rotation Z 1 has materialized , this circle 16 obviously being contained in the winding plane.

La comparaison des figures et plus particulièrement celle des figures 1, 8 et 9 permet de comprendre le processus de bobinage réalisé selon l'invention.The comparison of the figures and more particularly that of Figures 1, 8 and 9 makes it possible to understand the winding process carried out according to the invention.

La figure 8 matérialise vu de l'axe X l'angle α de rotation du bras 4 supportant la pièce 15. L'angle α pour des questions de facilité peut être repéré par rapport à la droite A' A verticale, parallèle à l'axe Y et passant par les axes X1 et X2.Figure 8 materializes seen from the X axis the angle α of rotation of the arm 4 supporting the part 15. The angle α for ease of reference can be identified relative to the straight line A 'A vertical, parallel to the Y axis and passing through the X 1 and X 2 axes.

De même, la figure 9 représente, vue de l'axe Y l'orientation angulaire β de la colonne 11 autour dudit axe'Y. Pour des questions de facilité, l'angle β peut être repéré à partir de la droite B' B qui n'est autre dans l'exemple illustré que la trace sur le plan du socle 2 des axes X1, X2'.Likewise, FIG. 9 represents, seen from the Y axis the angular orientation β of the column 11 around said axis ' Y. For reasons of convenience, the angle β can be identified from the line B' B which is none other in the example illustrated than the trace on the plane of the base 2 of the axes X 1 , X 2 '.

D'autre part, selon un mode de mise en oeuvre avanta- geux de l'invention, la demi-bague 15 sera supportée en bout du support 41, 42 sensiblement dans son plan médian et sur sa petite tranche. De façon pratique, la fixation pourra se faire en venant coller sur la demi-bague tronconique en ferrite 15 un peigne 17 en matériau plastique qui comprendra des dents 18 dans lesquelles viendront se loger les spires 19 enroulées assurant un bon positionnement et évitant tout glissement ultérieur. Le bras support 42 pourra être pourvu à son extrémité d'une pince qui recevra la partie médiane du peigne.On the other hand, according to an embodiment advantageous g e ux of the invention, the half-ring 15 is supported at the end of the support 4 1, 4 2 substantially in its median plane and on its small slice. Conveniently, the fixing can be done by coming to stick on the frustoconical half-ferrite ring 15 a comb 17 of plastic material which will include teeth 18 in which will be housed the coiled turns 19 ensuring good positioning and avoiding any subsequent sliding . The support arm 4 2 may be provided at its end with a clamp which will receive the middle part of the comb.

Avec une telle fixation de la demi-bague 15 dans son plan médian et par sa petite tranche, il est alors possible de réaliser un bobinage parfaitement symétrique de spires inclinées 19, 19' (voir figures 4 et 5) par rapport au plan médian 20, l'angle d'inclinaison des spires pouvant être choisi à chaque moment en choisissant le programme d'enroulement, c'est-à-dire les angles α et conjugués utilisés à chaque instant, et le nombre de spires devant être réalisé pour chaque valeur des angles α et β déterminés conjugués précitésWith such a fixing of the half-ring 15 in its median plane and by its small edge, it is then possible to produce a perfectly symmetrical winding of inclined turns 19, 19 '(see FIGS. 4 and 5) relative to the median plane 20 , the angle of inclination of the turns can be chosen at each moment by choosing the winding program, i.e. the angles α and conjugate used at each instant, and the number of turns to be produced for each value of the angles α and β determined conjugate above

D'autre part, il apparaît immédiatement que compte tenu de la fixation en position médiane de la bague, on obtiendra des spires 19, 19' parfaitement symétriques si on prend simplement soin de choisir des programmes d'enroulement identiques pour des angles α et β symétriques.On the other hand, it immediately appears that, given the fixing in the middle position of the ring, we will obtain perfectly symmetrical turns 19, 19 'if we simply take care to choose identical winding programs for angles α and β symmetrical.

Si l'on se reporte maintenant aux figures 6 et 7, on voit que selon l'art antérieur, le noyau constitué par une demi-bague ferrite 21 était tenu par une patte 22, par exemple collée au voisinage d'une tranche d'extrémité de la demi-bague 21, et sur la demi-bague ainsi tenue, on enroulait au moyen de bras enrouleurs tels que 121, 122 des spires dans des plans radiaux passant par l'axe 24 de la demi-bague 21'. Ces différents plans d'enroulement radiaux étaient obtenus en faisant pivoter les bras d'enrouleurs autour de l'axe 24 de la bague tenue fixe.If we now refer to Figures 6 and 7, we see that according to the prior art, the core constituted by a ferrite half-ring 21 was held by a lug 22, for example glued in the vicinity of a wafer end 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 winding arms around the axis 24 of the ring held fixed.

Au point de vue électromagnétique,.les bobinages ainsi obtenus sont bien moins efficaces que lorsque les spires sont disposées dans des plans inclinés comme selon l'invention.From an electromagnetic point of view, the windings thus obtained are much less effective than when the turns are arranged in inclined planes as according to the invention.

Bien entendu, l'invention n'est nullement limitée aux mode de réalisation illustré et décrit qui n'a été donné qu'à titre d'exemple, l'invention comprenant au contraire tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont réalisées suivant son esprit et mises en oeuvre dans le cadre des revendications qui suivent.Of course, the invention is in no way limited to the illustrated and described embodiment which has been given only by way of example, the invention on the contrary comprising all the technical equivalents of the means described as well as their combinations if these are carried out according to its spirit and implemented within the framework of the claims which follow.
