RU189074U1 - PLAZA FOR MANUFACTURING HARNESS WIRES WITH MAGNETIC WIRE HOLDERS - Google Patents

Abstract

The invention relates to technological equipment for the production of electrical products, in particular to equipment for the manufacture of wiring harnesses. The plazas for the manufacture of wiring harnesses are made in the form of an assembly table with magnetic wire holders attached to it, designed for clamping and branching the wires. The working surface of the plaza is alternating strips of magnetic and non-magnetic material, which makes it possible to adjust the force of detachment (fastening) of the holder during preparation or readjustment of the plaza for harness assembly.

Description

The technical field to which the utility model belongs.

The invention relates to technological equipment for the production of electrical installation products, in particular, to equipment for the manufacture of wiring harnesses.

The level of technology.

Nowadays, plazas with non-standard pins or forks are commonly used in the wiring industry. The disadvantages of this solution include the complexity of the preparation of the plaza, i.e. its changeover at release of new products. As a result, after applying such a plasma, it is necessary to store, and for a new product to prepare a new plasma. The use of the type clamps, for example, of the Panduit company, for the layout of the bundles, accelerates the layout process, but, as before, the laboriousness of the preparation of the plaza remains high, because Typical clamps have to be fixed with screws or screws, and, in addition, it is necessary to align clamps of various sizes with height.

Perforated plazas, whose clips are mounted on screws, are used. The manufacture of a perforated panel is very laborious, and to increase the rigidity of the panel it is necessary to install and fasten it to the crate. The manufacture of such a plaza is quite long compared to, for example, plywood plasom. The complexity of the preparation of perforated plaza is somewhat reduced due to the existing holes. However, if you lay on the plaza drawing, then access to the holes will be difficult.

A device for the manufacture of wiring harnesses, containing a panel with holes, pneumatic cylinders with pistons and studs rods mounted coaxially with the holes of the panel and connected pneumatic channels with a pneumatic system. Depending on the required configuration of the harness, on command from the control unit, the corresponding studs-rods move upwards relative to the panel surface. (SU 928688, publ. 05/15/1982). The disadvantage of this device is the complexity of its manufacture, and, accordingly, the high cost.

Another comprehensive, but extremely expensive solution is the assembly table with an interactive assembly panel. This is a fully computerized equipment that displays a prepared drawing and a harness layout program on a large screen. The advantage of the system is that it practically does not allow the operator to make a mistake. The program provides step-by-step maintenance of the operator when assembling the harness with the control of incoming wires on the bar code. This equipment also uses typical clamps, turns and splitters from Panduit, which are installed on the assembly table by means of vacuum suction cups (https: //www.youtube.corn/watch? V = UCgg-HnsWsU from 11/23/2014).

The disadvantages of the system used include the high cost, bulkiness and high cost of manufacturing vacuum fixings for clamps, as well as the need to use an absolutely smooth surface (glass) for installing vacuum fixings. But even in this case, after a few days, the vacuum depth gradually decreases and the heavy vacuum support spontaneously “sticks off” from the place intended for it.

The closest to the proposed utility model is a plaz for the manufacture of wiring harnesses with magnetic holders (RU 167361, publ. 10.01.2017). The plaza is made in the form of an assembly table, covered with a sheet of magnetic material, on the surface of which magnetic wire holders are fixed. The advantages of magnetic holders of wires over known structures are:

Quick preparation of the plaza for the layout of the new tow;

Fastening at any point of the assembly table;

No cost for the development and manufacture of improvised fasteners;

Reducing the cost of additional new plazas and their storage;

The possibility of using inexpensive and rigid materials for the assembly table without peripherals;

Lower price compared to vacuum holders;

The absence of the effect of spontaneous “sticking” of the magnetic holders of wires even on inclined assembly tables;

Universality practically for any plaits.

The number, type of magnetic holders and their position on the mounting table is determined by the required configuration of the wiring harness, and the number of permanent magnets on the magnetic holder is determined by the necessary effort to detach the holder from the magnetic material of the mounting table, the shearing force and the unwinding moment. The disadvantage of this plaza design is that the pull-off force of the magnetic holder can be adjusted from the mounting table only by replacing it with another holder with a different tearing force. This significantly increases the duration of the plaza changeover when starting a new template for assembling wiring harnesses, and also creates the need for a set of magnetic holders with different tearing forces.

Disclosure of the utility model.

The task of the utility model is the creation of equipment for the manufacture of wiring harnesses, in particular, a plaza, which provides quick and accurate preparation of the plaza for the layout of the harnesses, the ability to quickly and reliably fasten the wire holders at any point of the assembly table, as well as a quick changeover of the plaza wires.

The task is solved by making sheet magnetic material in the form of strips separated from each other by strips of non-magnetic material across the entire width and length of the mounting table, while for more accurate and reliable installation of the holder on the template position under the strips of sheets of magnetic material are fixed lines magnets.

Brief description of the drawings.

The utility model is illustrated by drawings, in which:

in fig. 1 shows a general view of a plaza for making wiring harnesses with magnetic wire holders;

in fig. 2 - magnetic wire holder with clip.

Implementation of the utility model.

As shown in FIG. 1, the workplace (plaz) for the manufacture of wiring harnesses consists of a mounting table 1, magnetic holders 2, wires 3, a working surface formed by strips 4 of magnetic material and strips 5 of nonmagnetic material, lines of permanent magnets 6.

Mounting the plaza is the following process. On a plywood, wooden or other non-magnetic base of the assembly table, bars (strips) 5 of non-magnetic material, such as wood, plexiglass or plastic, are mounted parallel to each other at a distance equal to the width of the holder 2. In the space between the strips 5, the rulers of permanent magnets are placed the width of the mounting table 1, which are then closed with strips 4 of magnetic material, for example, carbon steel, so that the strips 4 and 5 form a single working surface.

FIG. 2 shows the design of the magnetic wire holder, which is the base 7, inside which the permanent magnet 8 is placed, and the clamp 9 for holding the wires fastens from above.

The installation of the magnetic holders 2 on the positions of the assembly table 1 is carried out in the following order:

1. Fixing the sheet (template) with a drawing of the harness to a scale of 1: 1 by fixing it with magnetic holders 2;

2. Pre-installation according to the drawing of each magnetic holder 2 on the strip 5 near the place of its installation on the strip 4;

3. The final installation of each magnetic holder 2 on the strip 4 by turning it with a shift into place.

The removal of the magnetic holders 2 when the assembly table is retooled to a new harness assembly scheme is carried out in the reverse order.

Thus, the use of alternating strips of magnetic and non-magnetic material on the working surface of the mounting table allows you to adjust the pull-off force of the magnetic holders at the start and changeover of any harness assembly schemes.

The proposed design of the plaza for the manufacture of wiring harnesses solves the following production tasks:

Universality of equipment for any types of harnesses;

Reducing the cost of equipment for the assembly of wiring harnesses;

Reducing the cost of manufacturing new plazov and their storage;

Reducing the duration of the preparation of the assembly table for the layout of harnesses;

Reducing the complexity and increasing the reliability of the assembly process of the harnesses.
