DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a process and a device for the production of a transponder unit comprising a coil and at least one electronic component, such as a chip or the like. The invention further relates to a transponder unit.
BACKGROUND OF THE PRIOR ART
U.S. Pat. No. 5,281,855 has disclosed a transponder unit which is insertable into a glass tube, with a coil which is arranged on a winding carrier and the winding wire ends of which are connected to the terminal surfaces of a chip. The chip is arranged on a substrate which itself is adhesively connected to the end face of the winding carrier.
WO 92/15105 has disclosed a process for the production of a transponder unit comprising a coil and a chip, wherein the component is directly connected to the coil, with a plurality of process stages in which the equipping of a winding tool with the component, winding of the coil in the winding tool, and connection of winding wire ends of the coil to terminal surfaces of the component in the winding tool are carried out. In the known process the winding of the coil takes place in so-called "flyer" processes in which a winding head rotates about the stationary coil.
U.S. Pat. No. 5,025,550 has likewise disclosed a process wherein the coil is wound by means of a "flyer" rotating about the stationary winding carrier. A similar process is also disclosed in NL-A-8 503 166. Further processes for the production of transponders are known from U.S. Pat. No. 5,050,292.
BACKGROUND OF THE INVENTION
For the production of the known transponder unit, the winding wire ends of the previously manufactured coil are connected to the terminal surfaces of the chip. For this purpose the previously manufactured coil must be brought into the position for the subsequent connection of the winding wire ends to the chip terminal surfaces. This necessitates gripping of the winding wire ends during the coil transport and subsequent placing of the winding wire ends onto the chip terminal surfaces for the following connection. As in particular the alignment of the winding wire ends on the terminal surfaces proves extremely difficult due to the micro-dimensions, in the above mentioned patent it is proposed that the terminal surfaces be enlarged in size.
OBJECT OF THE INVENTION
The object of the invention is to propose a process and a device which simplify the production of a transponder unit. It is a further object of the invention to propose a transponder unit in a design which simplifies the production of the transponder unit.
SUMMARY OF THE INVENTION
The process according to the invention for the production of a transponder unit with a coil and at least one electronic component, such as a chip or the like, wherein the component is connected to the coil directly or via a substrate, comprises a plurality of process phases in which the equipping of a winding tool with the component or substrate, winding of the coil in the winding tool, and connection of wire ends of the coil to terminal surfaces of the component or substrate in the winding tool take place in such manner that the winding tool serves as operating platform in all of the aforementioned process phases.
Thus in the process according to the invention both the production of the coil and its subsequent connection to the terminal surfaces of the component or substrate take place in the winding tool. The relative position of the components, which together form the transponder unit, is thus maintained during the whole of the production process. Transfer of the coil to the component or substrate for the establishment of the connection, and the re-positioning which is required due to the transfer, are thus unnecessary in the process according to the invention. This substantially simplifies the production of a transponder unit.
It proves particularly advantageous if, for the production of transponder units, the winding tool is moved in clocked fashion into operating positions assigned to the individual process phases. In this way it is possible for function
