  • the shape of the DVD and the shape of the individual halves correspond to the well-known compact disc.
  • two 0.6 mm thick data carrier halves are combined to form a 1.2 mm thick DVD.
  • a data carrier half is coated with adhesive or an adhesive figure, such as a ring-shaped adhesive track, is applied. Then this half is put together with the other half in a precisely defined manner. The entire gluing process is carried out under clean room conditions and free of static charges.
  • EP 443 797 proposed to coat two data carrier halves with adhesive and first to spherically bend one half of the data carrier and then to bring it into contact with the other.
  • the contact surface thus moves as an annular surface from the center to the outside.
  • the invention is therefore based on the object of further developing a generic method in such a way that air pockets between the data carrier halves are avoided when the data carrier halves are glued.
  • a tool for carrying out the method according to the invention is also proposed.
  • the object is achieved in that a data medium half is bent about an axis parallel to the data medium half before touching the data carrier halves.
  • the bending of the elastic data carrier half allows a precisely defined temporal and local contact sequence and thus a connection of the two data carrier halves with the complete exclusion of air bubbles. While in the case of flat data carrier halves coated with contact, the contact takes place on a line, by bending two data carrier halves and feeding the data carrier halves at an angle to one another, a selective contact can be achieved which, when the elastic data carrier halves relax, changes into a contact surface.
  • An initially selective contact can, however, also be achieved by applying the adhesive as a trace of the adhesive.
  • the curved disk half then only touches the unbent disk half at certain points and then on curved lines.
  • the adhesive track is preferably applied to the unbent data medium half, since the mechanism for bending the other data medium half can also be used as a feed device.
  • a preferred method variant provides that a flat data carrier half is moved towards the curved data carrier half. This allows a simple construction. A particularly advantageous, relative movement between the data carrier halves results from the fact that the curved data carrier half is held elastically and is being bent straight by the unbent data carrier half. This allows the adhesive surface to spread evenly with little technical effort.
  • the data carrier halves be moved relatively slowly towards one another when the data carrier half touches the adhesive of the other data carrier half. Since this point of contact tends to form bubbles, a Slowing down of the process at this point, facilitating the escape of air.
  • the two data carrier halves are connected via an adhesive track, they are advantageously held for a period of time in order to allow the adhesive ring to spread out due to capillary forces.
  • This period of time is preferably adjusted so that the adhesive ring has run inwards up to a so-called stacked bead on the data carrier plate.
  • the data carrier halves connected by an adhesive track are rotated for a period of time around an axis perpendicular to the data carrier halves.
  • the capillary force is superimposed by a centrifugal force which increases the flow rate in the outer edge area of the adhesive surface and reduces or stops the flow rate in the inner edge area of the adhesive area.
  • the tool for performing the method according to the invention has grippers for gripping at least one half of the data carrier and is characterized in that the grippers are movably arranged to bend the half of the data carrier about an axis parallel to one half of the data carrier.
  • the inventive, preferably on the outer edge of the data carrier half attacking grippers are thus not arranged on a circular line, but opposite each other, so that these grippers can be used to bend the data carrier half in accordance with the method according to the invention. It is not necessary that the bend of the disk half corresponds to exactly one circular arc. Understandably, any convex bend is possible, the curve of which is preferably precisely matched to a pre-calculated contact sequence between the data carrier halves.
  • the grippers be arranged elastically. When bending the data carrier half, this enables the grippers to be inclined relative to a perpendicular to the data carrier half.
  • the tool In order to avoid a displacement of the lower disk plate half relative to the upper disk half when the disk is being transported more quickly, it is proposed that the tool have a projecting element which can be inserted into an opening in the disk or in a disk half. This above element comes into contact with the data carrier during rapid, horizontal displacements and counteracts the inertia force of the data carrier.
  • the protruding element has a depression which cooperates with an elevation opposite it for centering. This facilitates the exact centering between opposing data carrier halves. Damage-free bending of a data carrier half is facilitated in that the tool has a support opposite the grippers with a surface that is angled to a data carrier half.

  • This process can be carried out at a higher speed, such as 7.4 x 10 -3 m / sec.

  • the DVD half 5 When using the touchpad 20, the DVD half 5 initially lies on angled surfaces 40, 41 of a support 42.

  • the data carrier half 5 While the data carrier half 5 rests on the angled surfaces 40, 41, the data carrier half 5 is centered by the chuck 45 (cf. FIG. 10). Even when the touchpad with its inner and outer suction heads 36, 37, 29, 43 is placed on the surface of the data carrier half 5, the data carrier half 5 remains positioned by the chuck 45, so that the data carrier half 5 does not slip when the touchpad 20 is placed on it (cf. Figure 11). Only when the data carrier half 5 is firmly gripped, the touchpaid 20 with the above gripper chuck 49 moves upward, so that the gripper chuck 49 no longer experiences any counterforce through the contact chuck 45 and penetrates into the opening 3 of the data carrier half 5. As a result, the gripped data carrier half 5 can also be moved horizontally very quickly without a change in position of the data carrier half 5 relative to the touchpad 20 due to inertial forces.

Abstract

Selon l'invention, pour coller des moitiés (1) de vidéodisque numérique, on applique une bande de colle (2) circulaire sur une de ces moitiés et l'autre moitié (5) est ensuite cintrée autour d'un axe parallèle à la moitié de support de données puis placée sur la première moitié de support de données, de telle sorte que des surfaces de contact ponctuelles se forment. Lorsque l'on soulève la première moitié de support de données, la moitié (5) de support de données cintrée est pressée de façon alignée, de sorte qu'il se forme une surface de contact annulaire. Cette surface de contact annulaire est alors agrandie de façon contrôlée grâce à des forces capillaires et centrifuges. Pour le maintien et la mise en place de la moitié de support de données cintrée, on utilise un outil de prise comportant des éléments preneurs de conception spéciale.
