Description
- The invention relates to a wire coiling device, particularly a coiling device of a wire cutting machine or an automatic assembly machine for assembling connectors with long wires attached. The wire coiling device guides the provided wire in a circular movement into a wire container. Furthermore, the invention relates to a method for coiling an electrical wire employing the wire coiling device.
- In today's automatic assembly machines (transfer lines) for assembling connectors with long wires attached (e.g. SRS pigtails or antenna cables), the wires hanging down from the work piece carrier and running along the assembly process for the connector. Therefore the lines are realized as transfer lines with a floor conveyor moving the long wires, placed on the conveyor, parallel to the assembly process.
- If the wires becoming up to 8m long, they laying down on the conveyor and it is rather difficult to unload them manual or automated after the assembly from the conveyor, as they interloop to each other. This becomes even worse, if a connector gets a pair of single wires connected (e.g. SRS pigtail with single wires). Another disadvantage is the layout of the transfer lines in regards to their flexibility. If there are many versions of the connector to be produced, the line becomes longer and longer, because additional process steps have to be queued up into the transfer line.
- There is a need in the art to provide a solution for the above mentioned problems with long wires processed on transfer lines.
- The objective technical problem to be solved could be seen in providing a device that improves the handling of long wires that are processed with cutting machines and especially transfer lines for wire harnesses.
- A wire coiling device according claim1 and the method for coiling an electrical wire according claim 15 solve these and other objects, which become apparent upon reading the following description.
- The present application relates to a wire coiling device comprising, a round cylindrical wire storage container and a wire guiding device. The wire guiding device comprising an universal joint comprising a first joint part, a second joint part and a pivot cross that movable links the first joint part and the second joint part. The first joint part is attached to a first end portion of a straight tube. The first joint part comprises a first wire opening, the second joint part comprises a second wire opening, the pivot cross comprises a third wire opening and the first end portion of the straight tube comprises a fourth wire opening. The center of the first wire opening, the second wire opening, third wire opening and the fourth wire opening are centered along a vertical axis. The guiding device comprises a turning means that moves a second end portion of the straight tube circular around the vertical axis.
- The disclosed invention solves the problems of long electrical wires processed with transfer lines by coiling up the electrical wires into round cylindrical wire storage containers attached onto work piece carriers. In this case the electrical wires disappear into a round box, mounted to the work piece carrier and do not hang down from the work piece carrier. For this reason the line layout can be designed as optimal as possible in regards to flexibility and size, e.g. by designing indexing table solutions for different processes or version. A special fixation (universal joint) keeps the electrical wire path until the entry into the guiding tube in the center point of the rotation (along the vertical axis Y) so that torsion forces act on the electrical wire get reduced. The straight tube also does not apply torsion forces on the electrical wire when passing the straight tube. If necessary the straight tube can comprise a separating wall, arranged inside the straight tube, continuing along the length of the straight tube, defining two channels extending along length of the straight tube. This design allows to coil two electrical wires in parallel at the same time, into the round cylindrical wire storage container. When the electrical wire exits the straight tube, the electrical wire has still its preferred shape as had in the package as delivered to the cutting machine. That's why the electrical wire forms itself in its preferred position into the round cylindrical wire storage container.

If the wire coiling device should be used standalone, the first plate at the second plate can be linked by arms or walls surrounding the movable parts.
- Advantageously, the first plate comprises a fifth wire opening and wherein the second plate comprises a sixth opening, wherein the fifth wire opening and the sixth opening are centered along the vertical axis. Due to this design the wire can be guided along the vertical axis, along the center of rotation. The fifth opening can be shaped in any shape as long as the electrical wire can be guided through. The sixth opening is shaped circular or oval, dependent on the requested shape of the wire loops. The sixth opening could be even rectangular shaped, as long as the second end portion of the straight tube can be moved around the vertical axis.
- Preferably, the sixth opening is sized to enable pivoting movement of the straight tube of at least 5° in relation to the vertical axis. To be able to form wire loops, the straight tube must be angled in a minimum angle to the vertical axis. A bigger angle results in wire loops with a bigger diameter.
- Advantageously, a second end portion of the straight tube protrudes trough the sixth opening. The electrical wire leaving the straight tube is not in danger to collide with the second plate. The straight tube cannot be moved to a range outside the predefined fixed opening. That protects the straight tube from damage.
