Description

The invention relates to a technology for the manufacture of CEA and, in particular, to a technology for automating processes for the manufacture of wire harnesses.

The purpose of the invention is to speed up and simplify the process and improve the quality of the harnesses. The drawing schematically shows the proposed device for implementing the proposed method.

The device comprises a base 1, a heat transfer agent 2, a shuttle 3, threaded by a reel 4, with a wire 5 passing through the hole 6 in the needle plate 7, a frame template with the base (for example, a fabric) 9 installed and fixed on it, a needle 10 with a thread 11 and collectively implements the functions of the sewing mechanism 12, shown by the dotted line. .....

The manufacture of wire harnesses is carried out as follows.

On the basis of 1 sewing mechanism 12, a frame template 8 is installed with the base (for example, fabric) 9 mounted and fixed on it 9 under the needle 10 with thread 11. Previously, the shuttle 3 is loaded with a coil 4 with a wire 5 wound on it, from which the bundle is made, and the thread 11 and the 5-wire is drawn to a certain length, leaving loose ends, as is usually done with a sewing machine. In this case, the wire 5 passes through the hole 6 in the needle plate-7. After this, an injection is made with a needle 10, a well-known standard cycle of the sewing machine is carried out, as a result of which the wire 5 is attracted by a thread 1.1 with a thread giver 2 and fixed to the underside of the base 9, and the needle 10 is raised above the surface of the base 9. Then moving the template 8 with the first 9 to a new position (in accordance with the alignment path of wire 5) relative to the base 1 of the sewing machine 12. In this case, the wire 5 is pulled out of the hole 6, located along the portion of the alignment path under the base 9. Afterto make the following needle stick 10, carried a new cycle of the sewing machine 1.2. As a result, the stretched section of wire 5 is again attracted to the bottom side of the base 9, and the thread 11 forms a stitch on the upper surface of the base 9. Continuing to move the pattern 8 with the base 9 along the alignment path of the wire 5, similarly, the continuous wire 5 is laid and fixed simultaneously. to the base 9. Having completed these operations along the entire route, make a tourniquet by simultaneously laying and securing the continuous wire 5. to the base 9.

At the end of the simultaneous laying and fixing operations of the continuous wire 5 to the base 9 with the sequential movement of the template 8 over all sections of the route, the finished harness from the wire 8 is located and fixed (sewn) to the base 9 with a thread 11. After that, the thread 11 and wire 5 cut off. c, and the bundle itself is cut from the base 9 along the contour in accordance with the configuration of the bundle.

This method can be implemented both by manually moving the pattern and controlling the sewing mechanism, and using program-controlled movement of the pattern and the drive of the sewing machine.

Using the proposed method for the manufacture of wire harnesses and a device for implementing the method allowed to increase the productivity of the manufacturing process, to simplify the process itself and the equipment used, in particular the template. An increase in productivity and simplification of the technology is achieved by combining the operations of laying and securing the expanded wires in a single, simultaneously executed process. In addition, a number of technological operations (in comparison with the prototype), for example, heating, evacuation, cooling, are generally excluded. The proposed method for making harnesses and a device for its implementation significantly simplified the template, turning it into a simple frame with the main one installed (for example, a stretched and fixed fabric on it). The use of a shuttle tucked with wire from which the harness is made made it possible to combine in one device and one process the layout and fixation of the wire in the harness. Thus, the need for a separate tool or layout device has disappeared

5 wires on the surface of the template. The quality of the harness increased, i.e. the wire of the manufactured bundle is attached to the base along the entire length during laying, which ensures the density of the wires in the bundle in all sections, the relative displacement of the wires is excluded, which, in turn, provides better preservation of the shape and size of the bundle. The proposed methods and device expanded the range of manufactured harnesses. Their use allows the manufacture of flat bundles with wires laid in one layer, next to each other. A separate operation in vis-uk has lost its meaning. An opportunity has appeared to produce bundles with low sectional height

high-performance, easy way on standard equipment (sewing machine) and high quality. The manufacturing process can be easily automated.
