Description

The invention relates to process equipment for preparing wires for installation, in particular for removing insulation from optical fibers, and can be used in the manufacture of communications equipment, as well as in instrument-making and electronic engineering.

A machine for measuring wire cutting and stripping their ends from isolation is known, which includes a marking mechanism and wire segments, a burning mechanism, and a carriage with wire grippers Tljj.

However, the known device does not provide high-quality processing of wiring, for example, optical light guides, since it is impossible to remove insulation from the insulation on the treated surface {wires. The purpose of the invention is to improve the quality of processing of mounting wires, for example, optical fibers, by eliminating insulation voltages on the treated surface of the wire.

The goal is achieved. The device contains a system for supplying air to the firing zone, equipped with two nozzles located on either side of the firing mechanism of the insulation, and the firing mechanism

The insulation contains two elements for limiting the burning zone, each of which is provided with a groove located at an angle to the axis of the wire, with the nozzles and the grooves arranged respectively axially.

FIG. 1 shows the proposed device, top view; in fig. 2 shows section A-A in FIG. 1, on

10 of FIG. 3 shows a section BB in FIG. FIG. 4 - moment of firing of insulation from the wire; in fig. 5 is a view of B in FIG. 4 (firing mechanism cover with on-groove isometric).

The device contains electromagnets 18, kinematically connected with 30 grippers 2 and 10. The device also includes an insulation firing mechanism consisting of an electric motor 19 connected to a floor 20, on which a housing 21 with covers 22 is attached. heating elements 23. Nozzles 3 and 4 are located on either side of the insulation firing mechanism. 1 ьн 22 are elements for limiting the burning zone IB of the lids 22 are made | grooves at an angle to the axis of the wire. 24. The nozzles and grooves are respectively axial. The device works as follows. The electromagnets 18 are turned off and the heating elements 23 are turned on. When the shaft of the electric motor rotates, the screw 7 moves the movable carriage 9 until the microswitch 11 operates. A signal is given to stop the electric motor 6 and turn on the electric motor 19. The yoke 20, moves, interacts with the axis 14, which is in contact with the mic switch 16. In accordance with the sequence diagram of operation, the electromagnet of the air distributor 13 is triggered after a certain timing, the motor 19 and the beam 20 are reversed, moving interacts with the axis 15 which contacts the microswitch 17. A signal is given to stop the motor 19, turn on the electromagnets 18, reverse the motor 6 When the shaft of the electric motor rotates, the screw 7 moves the movable carriage 9 until the microswitch 12 triggers. If the wire 24 is inserted into the device, then when the electromagnets 18 are disconnected, it is clamped by the grippers 2 and 10. When the electric motor 6 is turned on, the moving carriage 9 moves to the final position and, drawing the wire 24 for a predetermined length. The motor 19, the koromyslo 20 with the housing 21, in which the heating elements 23 are located, is switched on, lowers and produces a metered firing of the insulation of the wire 24. Through the determined one. time according to the cyclogram of operation through the nozzles 3 and 4 of the air duct 5 along the inclined grooves of the caps 22 air is supplied under pressure, which removes buildup of insulation from the wire 24. The motor 19 is reversed, the rocker arm 20 rises, electromagnets 18 are turned on, the clamps open 2 and 10. The wire 24 is removed from the burning zone and the moving carriage 9 is in its original position. The device will increase the production of optical conductors and improve the quality of their surface. Testing of the layout of the device showed that with the air supply directed along the inclined grooves to the melted insulation of the optical conductor, the percentage of usable conductors increased from 48 to 98%. Apparatus of the invention for preparing wires for installation, comprising a carriage with a wire grip, an insulation firing mechanism, characterized in that, in order to improve the processing quality of the installation wires, for example, optical fibers, to eliminate insulation sag on the treated surface of the wire, it contains an air supply system in the burning zone, equipped with two nozzles located on both sides of the insulation burning mechanism, and the insulation burning mechanism contains two elements to limit the burning zone Each of which is provided with a groove situated at an angle to the wire axis, the nozzles and the grooves are arranged axially, respectively. .
