The automatic machine for preparing wires for installation contains a wire feeding mechanism, which includes a drum 1, a torque device 2, a guide tip 3 and a conveyor 4 (FIG. 1-3), kinematically connected with the drive 5. On the conveyor 4 chain with the help of holders 6 (FIG. 5) placed spring-loaded pulling the grip 7 (figure 2, 5-7). The gripper 7 contains plates 8 and 9 o On each of the plates placed on roller 10 and 11, the spring 12 connects the plates 8 and 9. The rollers 10 and 11 have the opportunity to interact with the wedges 13 and 14 (Fig, 2). The wedge stop 13 is fixed motionless relative to the conveyor 4, and the wedge stop 14 has the ability to move along the conveyor.

Tray 15 consists of plates 16 (Fig. 1, 8 and 9), which are assembled on rod 17 connected with lever 18. Plates 16 are mounted on rod 17 in such a way that there are transverse slots 19 and 20 between them, the distance between which corresponds to the specified wire length.

Cutting mechanism: includes pneumatic cylinder 21 with knives (Figs 12 and 13).

The knife 22 is fixed on the bracket 23 connected to the body of the pneumatic cylinder 21, and the knife 24 is connected to the rod ... of the pneumatic cylinder 21, The mezanisms of stripping, twisting, fluxing and tinning are placed at the two ends of the cut wire.

The isolation removal mechanism (Fig. 14) includes a paired pneumatic cylinder 25 and flat grippers 26 with notch attached to holders 27 connected to the piston 28 of the pneumatic cylinder 25, the rod 29 of the pneumatic cylinder 25 is fixed. On the casing of the pneumatic cylinder 25 fixed cone guides 30, The twisting mechanism of the current-carrying cores (Fig.15) contains a paired pneumatic cylinder 31 and flat grippers 32 on the holders .33. The holders 33 are connected with the screw 34, on which a thread with a large pitch is cut. The screw 34 is pivotally connected to the rod 35 of the cylinder cylinder 31. The nut 36 is placed on the screw 34 and is stationary relative to the body of the pneumatic cylinder 31. In addition, the twisting mechanism of the core is provided with taper guides 37, whose bearing is made in the form of a bearing 38. The second rod 39 of the pneumatic cylinder 31 is fixed .

The mechanism of fluxing (figure 1) is a bath 40, heated by a spiral, One of the gear

(d rollers 41 are placed in the bath 40, and the second toothed roller 42 is spring-loaded.

The mechanism of tinning, similar to the mechanism of fluxing, contains a heated bath 43 and 43 and toothed rollers 44 and 45.

The rotary conveyor includes wheels 46 and 47 mounted on shaft 48. Wheel 47 can move along

20 to shaft 48. The shaft 48 is kinematically using a Maltese cross 49 connected to a drive shaft 50. Wheels 46 and 47 are provided with spring-loaded grippers 51 (figures 10 and 11). Spring loaded

25, the gripper 51 comprises a roller 52, on the axis 53 of which two lugs 54 are placed, each of which is connected to the shaft 55, on which the spring 56 is placed. The rods 55 are rigidly connected to the spring bar 57, and the spring bar 58 is fixed on the wheel 46 (47 ).

On the wheel 46 is placed the stop 59 (figure 1) to deflect the tray 15. In addition, the wheels 46 and 47 are equipped with stops 60 and 61 to interact with the grippers 51,

The mechanism for removing wires consists of hooks 62 located on wa40 lu 63 connected by a pulley 64 to shaft 48.

The device works as follows.

The wheel 47 is mounted relative to the cruise 46 at a distance corresponding to a predetermined length of the conductors. The wedge stop 14 is installed at the same distance from the wedge stop 13, the Plates 16 of the tray 15 are mounted on the rod 17 in such a way that the distance between the slots 19 and 20 also corresponds to the length of the conductors (and the distance between the wheels 46 and 47). Baths 40 and

55 43 are filled with flux and solder, respectively, the heating of these baths is activated.

The wire from the drum 1 through the trimming device 2 is fed to the direction 1485306

lug tip 3. When the spring-loaded pulling grip 7 attached to the chain of the conveyor 4 finds

on the wedge νπου 13, the plates 8 and 9 of the gripper 7 are divorced (figure 4), then under the action of the spring 12 they close and seize the wire. With further movement of the conveyor chain 4, the gripper 7 pulls the wire until it reaches the wedge stop 14 At this moment, under the action of the wedge stop 14, the gripping plates 8 and 9 are again set apart and the wire is released. Then the cutting mechanism is triggered and the knives 22 and 24 cut the wire of the desired length, which is located in the tray 15. The wheels 46 and 47 of the rotary conveyor through the Maltese cross 49, connected to the drive 50, are driven. When moving, the wheel 46 with its stop 59 acts on the lever 18 of the tray 15 and deflects the tray 15, the roller 52 of the spring-loaded gripper 51 slides against the stop 60, and the bar 57 is pressed and the gripper 51 removes the cut wire from the tray. Then, under the action of the spring 56, the strips 57 and 58 of the claw 51 clamp the ends of the wire. When turning the wheels 46 and 47 konve10

One step wire, fixed in the grippers 51, is fed to the mechanism for removing the insulation. When the isolation isolation mechanism is turned on, air is supplied to the first and then to the second chamber of the pneumatic cylinder 25. At the same time, the piston 28 moves and the holders 27, passing through the tapered guides 30, are compressed, gripping the ends of the wire with the clamps 26. Since the insulation stripping mechanisms are located on both sides of the cut wire, the wire is simultaneously clamped on both sides by the claws 26. As the rod 29 is fixed still when air is supplied to the second chamber.

Пнев pneumatic cylinder 25 25 grippers 26 begin to move along with the body of pneumatic cylinder 25, removing insulation from the ends of the wire.

Then the wheels 46 and 47 are moved one more step and feed the wire to the twisting mechanisms. When turned on

At the next position, the fluxing of the ends of the wire occurs. Wires pass between toothed rollers 41 and 42 made of copper. At the same time, flux from the bath 40 is applied to the ends of the wire. The tinning operation is performed by the next movement of the wheels 46 and 47 by one step and proceeds in the same way as the fluxing operation.
