Method for producing sub-assemblies

Abstract

A method for producing sub-assemblies such as wiring harnesses/cable ducts includes multiple work steps that are carried out in a common work area. The production process is simplified and sources of error are avoided as far as possible, in that the work steps are displayed optically in the work area.

Claims

1. A method for producing rail vehicle sub-assemblies that are linked by electrical connections, the method comprising: a plurality of work steps being carried out in a common working area designated for assembling a rail vehicle; optically visualizing the work steps in the working area by illuminating a cable, to be taken up, of one electrical connection, and thereby: visually indicating a cutting length next to the cable in the working area and/or illuminating a cutting point on the cable; illuminating a routing path for the electrical connections by a light source; and subsequently assembling the electrical connection in the routing path.

2. The method according to claim 1, which comprises performing an assembly at least partly manually.

3. The method according to claim 1, which comprises providing components for assembly with an identifier or fixed storage location, and wherein the visualizing step comprises visualizing according to the identifier or storage location.

Description

BRIEF DESCRIPTION OF THE DRAWING

(1) FIGURE shows an exemplary embodiment of the method according to the invention.

DESCRIPTION OF THE INVENTION

(2) The FIGURE shows an exemplary embodiment of the method. according to the invention in which the method steps are indicated by boxes. According to the method 1, in the first step 2 the respective identification labeling of the components to be installed is carried out. The storage location is communicated to a central control unit in step 3. In step 4, this central control unit computes the mounting location and triggers, in step 5, an optical unit of a light source to project the light beam produced by the light source into the working area in such a way that the routing path of the cable identified in step 2 is illuminated in step 6, wherein this can also be subdivided into a plurality of sections. If the work step is complete, the method 1 proceeds to the next work step until the component, i.e. the cable duct or wiring harness, is completely installed.

(3) In this system it is immaterial whether individual work steps are machine aided or mechanized. These would be the marking, drawing or inserting of cables. For ergonomic or technically necessary workplace configuration, the working area can likewise be rotated. This is advantageously performed e.g. by a tilt/turn table or similar devices. The position of said table can be both indicated and adjusted directly via a control system.
