Definitions

  • the present invention relates to a device for producing a coil winding from winding wire on a winding support with a winding head having a wire guide device and movable relative to the winding support. Furthermore, the invention relates to a method which can be carried out by means of this device for producing an electrically conductive connection.
  • Devices of the type mentioned above can be used in the manufacture of coil arrangements in which a wire conductor is wound around the winding support by means of a winding head to form a coil winding and wire ends of the winding wire are connected to connection surfaces of the winding support or those of adjacent components.
  • other devices namely a connecting device and a wire separating device, are required in addition to the winding head.
  • the procedure can be such that first a wire end is connected to a connecting surface by means of the connecting device, then the actual coil winding is formed around the winding support by means of the winding head, and finally the running wire end of the winding wire is carried out by means of the connecting device is connected to a further connection surface and is severed by means of the wire cutting device.
  • the present invention has for its object to provide a generic device or a method that enables the most compact possible construction and a reduction in manufacturing times.
  • the wire guide device, the connecting device and the wire separating device are integral devices of the winding head.
  • Such a device virtually creates a highly integrated winding head which, in addition to the actual wire guiding function when winding a wire conductor on a winding support, also simultaneously performs the functions of connecting the wire ends to the winding support or a separate connection surface support separate therefrom and the final wire cutting function.
  • Due to the combination in a structural unit the entire device is a compact arrangement, so that both in one and the same relative position with respect to the connection surface of the connection surface carrier Connection of the wire conductor to the pad as well as cutting the wire conductor can be done.
  • there are no intermediate routes during the establishment of the connection which arise from the fact that, in devices according to the prior art, the wire guide device must be guided from a connecting device to a separating device.
  • the device according to the invention is particularly suitable for producing coil arrangements, that is to say both for carrying out a winding process and for carrying out the connection technology
  • the device according to the invention can equally advantageously be used in general where it matters, at certain points To create connections between a wire conductor and a connection surface and to guide the wire conductor in the intermediate area with the winding / connecting device according to the invention, referred to here as the winding head, on a predetermined movement path from one connection point to the other connection point.
  • a winding process does not have to be carried out in every case, but also with a corresponding axis control of the winding / connecting device, a meandering course in one plane or any other wire course between two connection points can be generated.
  • the wire guide device, the connecting device and the wire separating device are combined in one tool head, the actuating or delivery elements necessary for the individual devices being arranged outside the tool head.
  • This structure means a miniaturization which enables the use of the device according to the invention even with the smallest connection areas, such as the connection areas of a chip which are only 100 micrometers x 100 micrometers as standard.
  • a wire deflection device is preferably assigned to the wire guide device, which enables a wire conductor which is supplied approximately parallel to the connecting device to be deflected transversely to the feed axis of the connecting device so that the wire conductor comes to rest between the connecting device and the connecting surface when the connection is made.
  • connection device is not limited to a particular type, but rather that any of the range of connection devices available, such as a thermode, a thermosonic connection device, a laser welding device etc., or a combination thereof , can be selected.

  • a laser welding device has proven to be advantageous, in which the laser power emitted by a laser source is conducted directly to the connection point by means of a glass fiber conductor.
  • the winding head itself does not have to be loaded by the device device forming the laser source, but can be arranged in a stationary manner from the winding head.
  • the fiber optic cable can then be used as a connecting device be integrated into the winding head. This makes it possible to use a high-performance laser welding device in the device according to the invention without disadvantageously increasing its mass due to the device device mentioned above.
  • the wire guide device can be combined with the connecting device, for example in the case of a thermosonic bonding head as the connecting device, the wire is fed through a capillary in the bonding head.
  • the separating device in a functional unit which is then composed of a wire guide device, connecting device and wire separating device.
  • An example of this would be a thermosonic bonding head provided with a wire guide capillary, which also has a separating edge formed in the wire contact area. This would allow a high level of integration to be achieved.
  • the wire deflection device is preferably formed from a suction device acting transversely to the feed axis of the wire guide device.
  • a suction air connection is required in the area of the connecting device for its implementation, which causes the wire conductor fed through the wire guide device approximately parallel to the feed axis of the connecting device to be deflected transversely to the feed axis of the connecting device as a result of the suction force, so that the connecting device can act on the wire conductor, for example by applying heat and pressure in the case of a thermode.
  • Another possibility is to provide a gripping device which can be pivoted transversely to the feed axis of the connecting device for the wire deflection device.
  • a possible embodiment of a wire deflection device which is similar in principle, but still preferable in terms of the achievable compactness, consists in making the wire guide device itself pivotable transversely to the feed axis of the connecting device, in order then to cooperate with the connection surface of the connection surface carrier which the wire conductor strikes, to cause such a deflection of the wire conductor that the wire conductor comes to rest between the connecting device and the connection surface.
  • the device according to the invention is constructed in such a way that the actuating or feed elements assigned to the individual devices are arranged in a tool head carrier which can be coupled to the tool head.
  • a connecting device of a certain type For example, the thermocompression method for a connection on a connection surface of a Kapton film and for a chip connection surface have been found the Thermosonic process as advantageous, and a combination of these processes is also conceivable.
  • the connecting device however, one and the same actuating or delivery element can always be used. Apart from a simple and quick tool head change, this has a favorable effect on the tool preparation costs.
  • actuating or delivery elements There are various options for executing the actuating or delivery elements. For example, they can be designed as compressed air actuators, such as piston / cylinder units, or as solenoid actuators.
  • This further wire guide device can be integrated in the connecting device.
  • a further advantageous measure for example to establish or increase the connection compatibility between the wire conductor material and the pad material, can consist in providing a protective gas supply device in the area of the connection device.
  • Another possible alternative is to provide a vacuum device in the area of the connecting device, for example by surrounding the entire tool head with a vacuum bell.
  • the protective gas supply device can also be assigned a coating device which enables an application of a protective layer to the connection point, for example the application of a passivation layer as corrosion protection, preferably while the protective gas is being applied to the connection point.
  • a camera in particular a CCD camera equipped with CCD (charge-coupled device) image sensors, which is attached to the tool head itself or also to the tool head carrier can.
  • CCD charge-coupled device
