DESCRIPTION:
BRIEF SUMMARY
The invention relates to an apparatus for wiring a connector according to the preamble of claim 1.
An apparatus of the above-mentioned type is for example disclosed in EP-A-0 390 080. For identifying a wire of a number of wires, for example, combined in a cable, the known apparatus requires that on the one hand each wire of the bundle must be connected to a connecting unit in a predetermined manner and a second physical electric contact must be made with each wire. Thereby, the known apparatus is rather complicated and the use of the apparatus is cumbersome.
The invention aims to provide an apparatus of the above-mentioned type which is made in a relatively simple manner and by means of which a connector can be wired with high speed.
To this end the apparatus according to the invention is characterized by the characterizing features of claim 1.
In this manner an apparatus is obtained by means of which a connector can be wired fully automatically in a very reliable manner and with a high speed.
Preferably, the apparatus is characterized by a colour camera for observing a separated wire, wherein the processing unit determines the colour code of the observed wire from the picture signal of the colour camera and retrieves the position of the corresponding contact in the connector to be wired from a table, whereafter the processing unit controls the shutter of the wire selection means for delivering the wire, controls the gripper moving means for feeding the delivered wire to the corresponding wire guiding means and controls the tool moving means for aligning the tool with the corresponding contact.
The invention will be further explained by reference to the drawings in which an embodiment of the apparatus according to the invention is schematically shown.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows schematically a perspective view of the main part of an embodiment of the apparatus according to the invention.
FIG. 2 shows a very schematical perspective view of some important/components of the apparatus of FIG. 1.
FIG. 3 shows very schematically a side view of the part
FIG. 4 shows very schematically a top view of a part of the apparat s of FIG. 1.
FIG. 5 is a block diagram of the apparatus of FIG. 1.
FIG. 6 is a front view of an alternative embodiment of the wire selection means for use in the apparatus of FIG. 1.
FIG. 7 shows a flow diagram for the explanation of the method used in the apparatus of FIG. 1.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
FIGS. 1-5 schematically show an apparatus for wiring a connector 1 having a plurality of contacts 2 of the IDC-type. FIG. 1 partially shows a perspective view of the main part of the apparatus and FIGS. 2-4 very schematically shows different views to further explain the basic elements of this apparatus.
The apparatus comprises a holder 3 in which the connector 1 to be wired is placed, wherein a wire insertion head 4 is located at each side of the holder 3, said wire insertion head having a tool 5 movable back and forth transverse to the longitudinal direction of the holder 3. Each wire insertion head 4 further comprises a wire guiding means 6 into which a wire to be connected to a contact 2, can be brought. The wire insertion heads 4 are movable in the longitudinal direction of the holder 3 by a driving means 7 indicated in the block diagram of FIG. 5, so that the tools 5 can be aligned with each contact 2 of the connector 1 located in the holder 3.
The apparatus further comprises wire selection means which are mounted in a predetermined fixed position. The wires are generally part of a cable 8 which is clamped in a cable clamp 9 schematically shown. The wires 10 are inserted into an insertion opening 11 of a stationary located wire selection plate 12 which is part of the wire selection means. A selection slot 13 is provided in the wire selection plate 12, said slot 13 joining the insertion opening 11 at one side and at the other side debouching with an outlet in an edge of the wire selection plate 12 lying below the insertion opening 11. The wires 10
